This disclosure relates to the field of communication technologies.
The multiple-input multiple-output (MIMO) technology is one of key technologies for 5G mobile communications. MIMO is able to provide higher channel capacities, but realization of the benefits is dependent on whether accurate channel state information is able to be acquired. In the MIMO technology, a terminal equipment measures spatial channels and feeds back channel state information (CSI) to a network device. The network devices may select a precoding matrix appropriate for downlink transmission of the terminal equipment according to the channel state information reported by the terminal equipment, thereby minimizing a probability of error in receiving bits by the terminal equipment as much as possible.
A process for generating and feeding back channel state information may be summarized as follows. The network device transmits channel state information reference signals (CSI-RSs) to terminal equipments, and the terminal equipments estimate channels based on the received CSI-RSs to obtain estimation of spatial channel matrices. The terminal equipments further acquire CSI by utilizing the estimated spatial channels. In the New Radio (NR) technology, a mode for feeding back the CSI is implicit feedback, that is, the terminal equipments feed back the CSI by recommending transmission parameters to the network device, wherein the transmission parameters include a channel state indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a synchronization signal block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI) and physical layer RSRP (L1-RSRP). A base station may perform downlink transmission by directly using the parameters recommended by the terminal equipments, or it may not use the recommended parameters.
In a frequency division duplex (FDD) system, for a downlink, when a network device performs precoding by using information of a downlink channel, a terminal equipment is needed to feed back downlink channel state information to the network device via an uplink. However, as the information of the downlink channel is directly proportional to the number of antennas of the network device, in s scenario of massive MIMO, a huge number of antennas of the network device will lead to a very large amount of feedback of channel state information of the downlink channel. The Third generation portionnership Project (3GPP) has designed enhanced codebooks (such as Type II codebook) for downlink feedback, in which the amount of feedback of the channel state information is reduced through frequency domain compression. However, for valuable uplink resources, there is still a need to further reduce an amount of uplink feedback.
With the development of artificial intelligence/machine learning (AI/ML) technologies, applying the artificial intelligence/machine learning technologies to physical layers of wireless communication to solve difficulties of related methods has become a current technological direction.
It should be noted that the above description of the background is merely provided for clear and complete explanation of this disclosure and for easy understanding by those skilled in the art. And it should not be understood that the above technical solution is known to those skilled in the art as it is described in the background of this disclosure.
In performing CSI feedback by using codebooks, priorities may be set for the CSI, and a terminal equipment may feed back the CSI in an order of high priority levels (priority reporting levels) (for example, numeral values thereof are small) to low priority levels (for example, numeral values thereof are large). In addition, in a case where a portion of CSI needs to be omitted, the terminal equipment may omit CSI in a priority order, wherein the priority order is an order set according to the priority levels. For example, an order of numeral values of the priority levels from high to low is the priority order, that is, the higher a numeral value of a priority level, the earlier CSI is omitted.
It was found by the inventors of this disclosure that a technology of how to omit CSI generated based on AI/ML is not concerned in the related art. Hence, when a terminal equipment omits at least some information in the CSI generated based on AI/ML, an ambiguity may arise when the network device reads the received CSI. Furthermore, for the CSI generated based on AI/ML, how to set priority orders of the CSI is also not concerned in the related art.
In order to solve at least one of the above problems or other similar problems, embodiments of this disclosure provides a method and apparatus for transmitting and receiving channel state information and a communication system, in which first information of CSI generated based on AI/ML is omitted according to a priority order of the CSI and/or first configuration information, thereby omitting the CSI generated based on AI/ML, and avoiding an ambiguity possibly generated when a network device reads the CSI.

An advantage of the embodiments of this disclosure exists in that the terminal equipment is able to omit the CSI generated based on AI/ML, thereby avoiding an ambiguity possibly generated when the network device reads the CSI.

In the following embodiments of this disclosure, there exists a pairing relationship between an AI/ML-based CSI generation portion and an AI/ML-based CSI reconstruction portion, the former being applicable to a terminal equipment side, and the latter being applicable to a network device side. If the terminal equipment uses an AI/ML-based CSI generation portion, the network device must use an AI/ML-based CSI reconstruction portion paired with the AI/ML-based CSI generation portion to successfully reconstruct channel information. If the network device uses an AI/ML-based CSI reconstruction portion, the terminal equipment must use an AI/ML-based CSI generation portion paired with the AI/ML-based CSI reconstruction portion to successfully reconstruct channel information at the network device side.
The AI/ML-based CSI generation portion includes an AI/ML model, which may be used to generate more than one of precoding matrix information, a rank indicator (RI), a layer indicator (LI), a channel resource indicator (CRI) and a channel quality indicator (CQI). In addition, the RI, LI, CRI and CQI may not be generated by the AI/ML model. For example, the AI/ML-based CSI generation portion may further include more than one of a module for generating an RI, a module for generating an LI, a module for generating a CRI, and a module for generating a CQI. The AI/ML-based CSI generation portion may further include other modules, such as a module for truncating a bit sequence.
The information of the AI/ML-based CSI generation portion may be composed of AI/ML model information and/or information of a module for generating an RI and/or information of a module for generating an LI and/or information of a module for generating a CRI and/or information of a module for generating a CQI and/or information of a module for truncating a bit sequence and/or information of modules for implementing other functions (if any).
The AI/ML model may include three parts, a preprocessing module, an AI/ML encoder and a quantizer. Hence, the AI/ML model information may include preprocessing module information, AI/ML encoder information, and quantizer information. For example, a piece of AI/ML model information may be described by using “preprocessing module #2,AI/ML encoder #4,quantizer #A”. In addition, the preprocessing module, AI/ML encoder and quantizer may also be regarded as a whole to annotate the AI/ML model information, that is, AI/ML model information may also be denoted as, for example, AI/ML model information #4,etc.
The AI/ML reconstruction model of the AI/ML-based CSI reconstruction portion paired with the AI/ML model in the AI/ML-based CSI generation portion may also include three parts, a de-quantizer, an AI/ML decoder and a post-processing module. Hence, the AI/ML reconstruction model information may include de-quantizer information, AI/ML decoder information and post-processing module information. For example, a piece of AI/ML reconstruction model information may be described by “de-quantizer #B, AI/ML decoder #1, post-processing module #2”. In addition, the AI/ML reconstruction model information may also be expressed as, for example, AI/ML reconstruction model #1, or may be simply referred to as AI/ML model #1, so as to express a pairing relationship between it and AI/ML model #1 in the AI/ML-based CSI generation portion.
The AI/ML model may also be composed of two parts (for example, it does not include the preprocessing module, or the preprocessing module is included in the AI/ML encoder, and is regarded as a whole with the AI/ML encoder), that is, the AI/ML model includes an AI/ML encoder and a quantizer. At this time, the AI/ML model information may be composed of AI/ML encoder information and quantizer information. The AI/ML reconstruction model of the AI/ML-based CSI reconstruction portion paired with the AI/ML model may also also be composed of two parts, a de-quantizer and an AI/ML decoder. At this time, the AI/ML reconstruction model information is composed of de-quantizer information and AI/ML decoder information. The preprocessing module may be contained in the AI/ML encoder, or may not be included in the AI/ML encoder. The post-processing module may be contained in the AI/ML decoder, or may not be included in the AI/ML decoder.
The AI/ML model may also be composed of one part, that is, the AI/ML encoder and the quantizer are regarded as a whole (for example, the AI/ML encoder and the quantizer are inseparable and cannot be freely combined), and the AI/ML encoder may or may not include a preprocessing module. At this time, the AI/ML model information is only composed of one part, for example, the AI/ML model information is AI/ML model #5. The AI/ML reconstruction model may also be composed of one part, that is, the de-quantizer and the AI/ML decoder are regarded as a whole (for example, the AI/ML decoder and the de-quantizer are inseparable and cannot be freely combined), and the AI/ML decoder may or may not include a post-processing module. At this time, the AI/ML reconstruction model information is only composed of one part. For example, the AI/ML reconstruction model information is AI/ML reconstruction model #5, or is simply referred to as AI/ML model #5, so as to express a pairing relationship between it and AI/ML model #5 in the AI/ML-based CSI generation portion.
In the embodiments of this disclosure, report may refer to an action of transmitting information by a terminal equipment to a network device. For example, reporting CSI by the equipment may refer to transmitting the CSI by the terminal equipment to the network device.
The embodiments of the first aspect provides a method for transmitting channel state information (CSI), applicable to a terminal equipment, such as the terminal equipment 202 in
In at least one embodiment, the terminal equipment may execute operation 302 for such cases as occurrence of CSI conflicts, limited uplink resources, or conservation of uplink resources, etc., wherein the uplink resources include physical uplink shared channels (PUSCHs) and/or physical uplink control channels (PUCCHs), etc. For example, the omitting the first information of the CSI in operation 302 may occur in CSI report carried by a physical uplink shared channel (PUSCH) and/or CSI report carried by a physical uplink control channel (PUCCH).
With the embodiments of the first aspect, the terminal equipment may omit the CSI generated based on the AI/ML model, thereby avoiding possible ambiguities that may arise when the network device reads the CSI.
In at least one embodiment, in operation 301, at least a portion of the CSI generated by the terminal equipment includes two parts, a first part (part 1) and a second part (part 2), wherein the first part of the CSI includes a rank indicator (RI) and/or at least a portion of a channel quality indicator (CQI) and/or a channel state information reference signal resource indicator (CRI), and the second part of the CSI includes information on a precoding matrix and/or at least a portion of a channel quality indicator (CQI) and/or a layer indicator (LI), wherein at least the information on the precoding matrix is generated based on the artificial intelligence model. However, this disclosure is not limited thereto, and other information in the CSI may also be generated based on the artificial intelligence model. For example, at least a portion of the channel quality indicator (CQI) and/or the layer indicator (LI) in the second part of the CSI may be generated based on the artificial intelligence model.
The first information of the CSI omitted in operation 302 may be at least a portion of information in the second part of the CSI, such as a portion of part 2 information of the CSI omitted in operation 302, or all information of part 2 of CSI omitted in operation 302. When the terminal equipment omits all the information of part 2 of the CSI, the network device may take an identity matrix as a precoding matrix used in downlink transmission.
In at least one embodiments of operation 302, the terminal equipment may omit the first information of the CSI according to the priority orders of the CSI. For example, the first information of the CSI may be omitted in a priority order from low to high, wherein information with lower priority orders (e.g. numbers to which the priority orders correspond are smaller) is omitted first, and information with higher priority orders (e.g. numbers to which the priority orders correspond are larger) is omitted later.
In at least one piece of CSI report, the priority orders of the CSI may be set according to information on a layer of part 2 and/or information on predetermined bits in the layer. For example, the priority orders are set according only to the information on a layer, or, the priority orders are set according to the information on a layer and the information on predetermined bits, or, the priority orders are set according only to the information on predetermined bits. For example, in a case where the CSI has only one layer, the priority orders are set according only to the information on predetermined bits.
In at least one embodiment, mapping relationships may be formed between the priority orders and the information a layer and/or the information on predetermined bits in the layer, and there may be one or at least two groups of mapping relationships. The priority orders of the CSI may be determined according to the mapping relationships.
In the case where there are at least two groups of mapping relationships, the priority orders of the CSI may be set based on one of the at least two groups of mapping relationships. The group of mapping relationships may be preset, or may be selected by the terminal equipment (e.g. terminal equipment 202), or may be configured by the network device (e.g. network device 201), wherein in the case where the group of mapping relationships is selected by the terminal equipment, the terminal equipment may receive information transmitted by the network device, the information instructing the terminal equipment to transmit information on the group of mapping relationships to the network device, and the terminal equipment may transmit the information on the group of mapping relationships to the network device according to the information. Hence, the network device may learn a mode for setting the priority orders of the CSI. The information on the group of mapping relationships may include such information as indices of the group of mapping relationships, etc.
In at least one embodiment, in CSI report, part 2 has one layer or at least two layers. In the case where part 2 has at least two layers, each layer may be generated based on identical artificial intelligence models, or the at least two layers are generated based on different artificial intelligence models.
In at least one embodiment, the information on a layer includes an order of the layer, wherein the order of the layer may be set according to an arrangement order of an eigenvalue or singular value of a spatial channel matrix to which the layer corresponds. For example, the larger the eigenvalue or singular value to which the layer corresponds, the higher the order of the layer, and the higher the priority order of the CSI to which the layer corresponds, that is, the more backward the CSI of the layer, the more possible it is omitted.
In at least one embodiment, the information on predetermined bits may include a proportion of the predetermined bits in a bit sequence to which the layer corresponds.
In the case where part 2 of the CSI report has at least two layers, for different layers, the proportion is equal; or, for the at least two layers, the proportion is not equal.
The number of the predetermined bits, i.e. the number of bits, may be determined according to the proportion. For example, a total number of bits in the bit sequence to which the layer corresponds may be multiplied by this proportion, and the obtained result is rounded up (such as rounding up, rounding down, rounding off), and the resulting number is the number of the bits.
In at least another embodiment, the information on predetermined bits may include the number of the predetermined bits, that is, the proportion is replaced by the number of the predetermined bits. Thus, the number of the predetermined bits may be determined more directly.
In the case where part 2 of the CSI report has at least two layers, for different layers, the numbers of the predetermined bits are identical; or, for the at least two layers, the numbers of the predetermined bits are different.
In at least one further embodiment, the information on predetermined bits further includes positions of the predetermined bits in the bit sequence to which the layer corresponds. For example, a certain number or proportion of the predetermined bits are located at front, or back, or odd or even positions of the bit sequence.
In at least one embodiments of this disclosure, the information on predetermined bits may be preset information, or, the information on predetermined bits is configured by the network device, or, the information on predetermined bits is determined by the terminal equipment, and the terminal equipment further reports the information on predetermined bits to the network device.
It should be noted that in tables and words of this application, “a priority order N (N is a non-negative integer, for example, N is 1, 2, and 3, etc.)” may be referred to as a priority level N, or may be referred to as “a priority order level N”, or may be referred to as “a priority reporting level N”, or may be referred to as “a priority order value N”, etc.
A specific mode for omitting the first information of the CSI according to the priority order of the CSI in operation 302 shall be described below by way of several examples.
In the following examples, it is assumed that there total M (M is a natural number) pieces of CSI report, meanings of priorities of the M pieces of CSI report being different from a meaning of the priority order of the CSI. The priorities of the CSI report may be determined based on relevant techniques. In the following examples, it is assumed that the CSI report has 4 layers respectively and M=3. In the CSI report, the priority order of part 2 of the CSI may be according to the information on a layer and regulations, as shown in tables 1˜4 below.
Tables 1˜4 are two examples of the priority order of the CSI. In Tables 1 and 2, the order of layers is arranged in a descending order of eigenvalues or singular values of the spatial channel matrix, wherein a rank of the spatial channel matrix is equal to the number of matrix eigenvalues or singular values. The total number of the layers is identical to that of RIs, and an RI is less than or equal to the rank.
In Table 1, the terminal equipment may omit the first information of the CSI in a descending order of values of the priority orders.
In Table 1, #1˜ #4 denote different mapping relationships. In the mapping relationship shown in #1, the priority order of the CSI is set based on the information on a layer. In the mapping relationships shown in #2, #3 and #4, the priority order of the CSI is set based on the information on a layer and the information on predetermined bits in the layer, wherein the information on predetermined bits includes a proportion of the predetermined bits.
In Table 1, for the mapping relationship shown in #2, “a certain proportion of bits” may be identical for all priority orders, or, proportions of at least two priority orders are different.

In Table 1, for the mapping relationship shown in #4, “a certain proportion of bits” may be identical for all priority orders, or, proportions of at least two priority orders are different.
In Table 1, the method for calculating the number of bits based on a “a certain proportion of bits” may be predetermined, or may be configured by the network device. For example, the number of bits in the bit sequence to which the layer corresponds may be multiplied by the proportion, and the result is rounded in a certain manner, such as rounding up, rounding down, and rounding off, etc.
In Table 1, “a certain proportion of bits” and/or positions of the certain proportion of bits in the bit sequence may be predetermined, or may be configured by the network device, or may be determined by the terminal equipment. For example, the certain proportion of bits and their positions may correspond to: former K bits in the bit sequence, or, latter K bits in the bit sequence, or, K bits, wherein priority orders of odd bits are lower than those of even bits, or, K bits, wherein priority orders of even bits are lower than those of odd bits; however, it is not limited thereto. In the case where it is/they are configured by the network device, the network device may transmit index 1 to the terminal equipment, index 1 being used to indicate the certain proportion of bits and/or positions of the certain proportion of bits in the bit sequence. For the case where it is/they are configured by the terminal equipment, the terminal equipment may report index 2 to the network device, index 2 being used to indicate such information as the certain proportion of bits and/or positions of the certain proportion of bits in the bit sequence determined by the terminal equipment, etc. Positions of index 1 and index 2 in a feedback bit sequence may be specified in standards or agreed upon in advance by the network device and the terminal equipment.
In some implementations, the priority order of the CSI may only have one specification, such as a mapping relationship to which a column in Table 1 corresponds. The terminal equipment may omit the first information in the CSI according to the priority order of the CSI.
In some implementations, the priority order of the CSI may have at least two specifications, such as mapping relationships to which at least two columns in Table 1 correspond. According to configuration of the network device, the terminal equipment may determine which group of mapping relationships is used to set the priority order of the CSI and omit the CSI; or, the terminal equipment may determine by itself which group of mapping relationships is used to set the priority order of the CSI, omit the CSI, and feed back indices of the group of mapping relationships to the network device. Positions of the indices of the mapping relationships in the feedback bit sequence may be provided in standards or agreed upon in advance by the network device and the terminal equipment.
In the examples shown in tables 2 and 3, it is assumed that M=3 and there are 3 pieces of CSI report. As marked in tables 2 and 3, the number of bits of part 2 of the CSI of priority order k is marked as nk, then ak≤nk, by <nk, Ck≤nk and k=1, 2, . . . 12. nk, k=1,2,3,4, which may be equal, or more than two nks are not equal.nk>k=5,6,7,8, which may be equal, or more than two nks are not equal.nk, k=9,10,11,12, which may be equal, or more than two nks are not equal. The 12 aks may be equal, or more than two aks are not equal. The 12 bks may be equal, or more than two bks are not equal. The 12 cks may be equal, or more than two cks are not equal.
In table 2 or table 3, the terminal equipment may omit the first information of the CSI in a descending order of values of the priority orders.
In table 2 or table 3, #1˜ #3 denote different mapping relationships. In the mapping relationships shown in #1, #2 and #3, the priority order of the CSI is set according to the information on a layer and the information on predetermined bits in the layer, wherein the information on predetermined bits includes the number of predetermined bits, i.e. the number of bits, such as the numbers of bits ak, bk, and ck, etc., in table 2 or table 3. For the same priority order, ak, bk and bk may be identical, or at least two thereof are different.
In table 2 or table 3, the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence may be predetermined, or may be configured by the network device, or may be determined by the terminal equipment. For example, the number of the predetermined bits and their positions may correspond to: former K bits in the bit sequence, or, latter K bits in the bit sequence, or, K bits, wherein priority orders of odd bits are lower than those of even bits, or, K bits, wherein priority orders of even bits are lower than those of odd bits; however, it is not limited thereto. In the case where they are configured by the network device, the network device may transmit index 3 to the terminal equipment, index 3 being used to indicate the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence. For the case where they are determined by the terminal equipment, the terminal equipment may report index 4 to the network device, index 4 being used to indicate such information as the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence determined by the terminal equipment, etc. Positions of index 3 and index 4 in a feedback bit sequence may be specified in standards or agreed upon in advance by the network device and the terminal equipment.
In some implementations, the priority order of the CSI may only have one specification, such as a mapping relationship to which a column in table 2 or table 3 corresponds. The terminal equipment may omit the first information in the CSI according to the priority order of the CSI.
In some implementations, the priority order of the CSI may have at least two specifications, such as mapping relationships to which at least two columns in table 2 or table 3 correspond. According to configuration of the network device, the terminal equipment may determine which group of mapping relationships is used to set the priority order of the CSI and omit the CSI; or, the terminal equipment may determine by itself which group of mapping relationships is used to set the priority order of the CSI, omit the CSI, and feed back indices of the group of mapping relationships to the network device. Positions of the indices of the mapping relationships in the feedback bit sequence may be provided in standards or agreed upon in advance by the network device and the terminal equipment.
In an example to which table 4 corresponds, it is assumed that M=3 and there are 3 pieces of CSI report. In the example to which table 4 corresponds, the CSI report has only one layer of downlink transmission, i.e. there is only one layer. As marked in table 4, the number of bits of part 2 of the CSI of priority order k is marked as mk, then xk≤mk, yk≤mk, zk≤mk and k=1,2,3,4. nk, k=1,2,3,4, which may be equal, or more than two nks are not equal. The 4 xkS may be equal, or more than two xks are not equal. The 4 yks may be equal, or more than two yks are not equal. The 4 zks may be equal, or more than two zks are not equal.
In table 4, #1˜#3 denote different mapping relationships. As the example of table 4 has only one layer, in the mapping relationships shown in #1, #2 and #3, the priority order of the CSI is set according to the information on predetermined bits in the layer, wherein the information on predetermined bits includes the number of predetermined bits, i.e. the number of bits, such as the numbers of bits xk, yk, and zk, etc., in table 4. For the same priority order, xk, yk and zk may be identical, or at least two thereof are different.
In table 4, the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence may be predetermined, or may be configured by the network device, or may be determined by the terminal equipment. For example, the number of the predetermined bits and their positions may correspond to: former K bits in the bit sequence, or, latter K bits in the bit sequence, or, K bits, wherein priority orders of odd bits are lower than those of even bits, or, K bits, wherein priority orders of even bits are lower than those of odd bits; however, it is not limited thereto. In the case where they are configured by the network device, the network device may transmit index 5 to the terminal equipment, index 5 being used to indicate the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence. For the case where they are determined by the terminal equipment, the terminal equipment may report index 6 to the network device, index 6 being used to indicate such information as the number of predetermined bits and/or the positions of the predetermined bits in the bit sequence determined by the terminal equipment, etc. Positions of index 5 and index 6 in a feedback bit sequence may be specified in standards or agreed upon in advance by the network device and the terminal equipment.
In some implementations, the priority order of the CSI may only have one specification, such as a mapping relationship to which a column in table 4 corresponds. The terminal equipment may omit the first information in the CSI according to the priority order of the CSI.
In some implementations, the priority order of the CSI may have at least two specifications, such as mapping relationships to which at least two columns in table 4 correspond. According to configuration of the network device, the terminal equipment may determine which group of mapping relationships is used to set the priority order of the CSI and omit the CSI; or, the terminal equipment may determine by itself which group of mapping relationships is used to set the priority order of the CSI, omit the CSI, and feed back indices of the group of mapping relationships to the network device. Positions of the indices of the mapping relationships in the feedback bit sequence may be provided in standards or agreed upon in advance by the network device and the terminal equipment.
In some embodiments of operation 302, in the case where the terminal equipment omits the first information of the CSI according to the priority order of the CSI, the omitted first information may be all or a part of the CSI to which at least one priority reporting level in the priority order corresponds. “A priority reporting level N” may correspond to “a priority order N (N is a non-negative integer, for example, N is 1, 2, and 3, etc.)” in tables 1-4 or other tables, and may be referred to as a priority level N, or may be referred to as “a priority order level N”, or may be referred to as “a priority order value N”, etc.
In some examples, for a certain piece of CSI report, starting from a certain CSI priority reporting level in the used CSI priority order, if there are no enough uplink resources, the terminal equipment drops or omits information on CSI report to which the priority reporting level and a priority reporting level with a larger value correspond.
For example, for the case in table 1, there are four transport layers, and bitwidths of second information (for example, the second information refers to information output by AI/ML models used by the transport layers) of a first, second, third and fourth transport layers are 120 bits, 100 bits, 80 bits and 80 bits, respectively, that is, a sum of the bitwidths of the second information of all the layers is 380 bits. The CSI priority order given in column #2 of table 1 is used for the CSI report. For CSI report 3, numbers of “a certain proportion of bits” in the priority reporting levels 16, 17 and 19 of the CSI is a result obtained by multiplying the bitwidth of part 2 of the CSI in the transport layer in a value of the priority order respectively by 80%, 70% and 60% and rounding down. The uplink resources of the second information of all layers available for CSI report 3 are less than 380 bits, assuming that they are 340 bits, they are 40 bits less than the sum of the bitwidths of the second information of all layers. In this embodiment, there are 32 bits in CSI priority reporting level 21 and 24 bits in CSI priority reporting level 20. Even if there are 16 bits in the uplink resources (340 bits) available for transmitting bits in CSI priority order 20, according to the method in this example, all bits in CSI priority reporting level 20 and CSI priority reporting level 21 are omitted.
In addition, in this example, after receiving the CSI report from the terminal equipment, according to regulations in standards, the network device adds 24 “0” after a last bit of the received CSI of the third layer, and adds 32 “0” after adding bits to a last bit of the received CSI of the fourth layer. Hence, the network device recovers channel information.
In other examples, for a certain piece of CSI report, starting from a certain CSI priority reporting level in the used priority order of the CSI, there are insufficient uplink resources. The terminal equipment transmits information on bits of the number of bits that the uplink resources in information on the CSI report to which the CSI reporting level corresponds are sufficient to transmit, wherein the bits may traverse various possibilities (such as former K bits, latter K bits, a total K bits with even bits first and odd bits later, and a total K bits with odd bits first and even bits later, etc.). The terminal equipment drops/omits information on other bits of the information on the CSI report to which the CSI reporting level corresponds and information on all CSI report to which values larger than the priority reporting level correspond.
For example, the standards specify that the optional CSI priority orders are the three possibilities given in table 2. The terminal equipment has four transport layers. The bitwidths of the second information of the first, second, third and fourth transport layers are 120 bits, 100 bits, 80 bits and 80 bits, respectively. That is, the sum of the bitwidths of the second information of all the layers is 380 bits. For CSI report 3, a_9=120, a_10=80, a_11=60, a_12=40. The uplink resources of the second information of all layers available for CSI report 3 are less than 380 bits, assuming that they are 330 bits, they are 50 bits less than the sum of the bitwidths of the second information of all layers. The terminal equipment selects the CSI priority order given in column #1 of table 32 for CSI report, and reports information on the CSI priority order to a base station, which needs 2 bits. So there are still 330−2=328 bits of uplink resources available for the second information of all layers of CSI report 3. Uplink resources in the information on CSI report to which the priority reporting level corresponds transmitted by the terminal equipment are sufficient for transmitting bits of former K bits. According to the method in this example, CSI priority reporting level 24 (40 bits) is unable to be reported, and last 12 bits in CSI priority reporting level 23 are unable to be reported. In other words, former 8 bits in CSI priority reporting level 23 are reported, and remaining bits in CSI priority reporting level 23 and all bits in CSI priority reporting level 24 are omitted.
In this example, after receiving the report from the terminal equipment, according to contents in the report, the network device learns that the CSI priority order given in #1 column of table 2 is used for the CSI report. According to regulations in standards, the network device adds 12 “1” after a last bit of the received CSI of the third layer, and adds 40 “1” after a last bit of the received CSI of the fourth layer. Hence, the network device recovers channel information.
In this example, compared to the scheme of omitting all CSI in the third layer, in the scheme of omitting a part of CSI in the third layer, the part of information in the priority reporting level of the CSI where uplink resources are sufficient to report is reported. Therefore, all available uplink resources may be fully utilized.
In at least another embodiment of operation 302, the terminal equipment omits the first information of the CSI based on an omit criterion to which the first configuration information transmitted by the network device corresponds.
The omit criterion may include at least one parameter, the at least one parameter may include: the number of bits to which the omitted first information corresponds and/or positions of bits to which the omitted first information corresponds, and/or the number and/or positions of bits to which information reserved in the channel state information corresponds. The reserved information refers to information that needs to be reserved but not omitted in the operation of omitting the first information of the CSI by the terminal equipment.
The parameters in the omit criterion are predetermined parameters, or are obtained by configuring by the network device through parameter configuration information.
In at least one embodiment, the omit criterion may include at least one of the following:
Table 5 shows an example of the omit criterion.
In the example to which table 5 corresponds, the network device may transmit the first configuration information to instruct the terminal equipment to omit the first information of the CSI based on an omit criterion to which any configuration in configuration 0 to configuration 5 corresponds.
In table 5, positions of the omitted bits and/or positions of the reserved bits may be agreed upon or configured by the network device. For example, they may be former K bits in a bit sequence, or may be latter K bits, or may be K bits after odd bits are omitted first and then even bits are omitted, or may be K bits after even bits are omitted first and then odd bits are omitted; however, it is not limited thereto. The positions of the omitted bits and/or positions of the reserved bits may be one of one or at least two agreed upon between the terminal equipment and the network device, or may be agreed upon in advance. For the case where they are configured by the network device, they may be indicated by index 7 configured by the network device, wherein a position of index 7 in the feedback bit sequence may be specified by standards or agreed upon in advance by the network device and the terminal equipment.
According to the embodiments of the first aspect of this disclosure, the first information of the CSI may be omitted according to the priority order of the CSI generated based on the artificial intelligence model and/or the first configuration information, thereby omitting the CSI generated based on the artificial intelligence model, and avoiding an ambiguity possibly generated when the network device reads the CSI.
The embodiments of the second aspect provide a method for transmitting channel state information (CSI), applicable to a terminal equipment, such as the terminal equipment 202 in
Furthermore, as shown in
In some embodiments of operation 401, the at least a portion of CSI includes two parts: a first part and a second part, wherein the first part includes a rank indicator (RI) and/or at least a portion of a channel quality indicator (CQI) and/or a channel state information reference signal resource indicator (CRI), and the second part includes information on a precoding matrix and/or at least a portion of channel quality indicator (CQI) and/or a layer indicator (LI), wherein at least the information on the precoding matrix is generated based on the artificial intelligence model.
In at least one piece of channel state information report, the priority orders may be set according to information on a layer of the second part and/or information on predetermined bits in the layer.
In at least one embodiment, there may be one or at least two groups of mapping relationships between the priority orders and the information a layer and/or the information on predetermined bits in the layer. In the case where there are at least two groups of mapping relationships, the priority orders of the CSI may be set based on one of the at least two groups of mapping relationships.
The group of mapping relationships may be preset, or may be selected by the terminal equipment, or may be configured by the network device, wherein in the case where the group of mapping relationships is selected by the terminal equipment, the terminal equipment may transmit information on the selected group of mapping relationships to the network device.
In at least one embodiment, the information on a layer includes an order of the layer, wherein the order of the layer may be set according to an arrangement order of an eigenvalue or singular value of a spatial channel matrix to which the layer corresponds. For example, the larger the eigenvalue or singular value to which the layer corresponds, the higher the order of the layer.
In the CSI report, part 2 has one or at least two layers, and in the case where part 2 has at least two layers, the layers are generated based on identical artificial intelligence models, or, the at least two layers are generated based on different artificial intelligence models.
In at least another embodiment, the information on predetermined bits may include proportions of the predetermined bits in a bit sequence of the layer, and/or positions of the predetermined bits in the bit sequence. In the case where part 2 of the CSI report has at least two layers, for different layers, the proportions are identical, or, for the at least two layers, the proportions are different.
By multiplying a total number of bits in the bit sequence of the layer by the above proportions and rounding the result, the number of predetermined bits may be obtained.
In at least one further embodiment, the information on predetermined bits includes the number of the predetermined bits and/or positions of the predetermined bits in the bit sequence. In the case where part 2 of the CSI report has at least two layers, for different layers, the numbers of the predetermined bits are identical, or, for the at least two layers, the numbers of the predetermined bits are different.
In at least one embodiment, the information on predetermined bits may be preset information, or, the information on predetermined bits is configured by the network device, or, the information on predetermined bits is determined by the terminal equipment. In the case where the information on predetermined bits is determined by the terminal equipment, the terminal equipment further reports the information on predetermined bits to the network device.
According to the embodiments of the second aspect, for the CSI generated based on the artificial intelligence model, the priority order of the CSI may be set. Hence, the terminal equipment and the network device may perform corresponding processing and operations based on the priority order.
Properties of a spatial channel between a terminal equipment and a network device will change due to different positions of the terminal equipment or other reasons, and important bits of a bit sequence of channel state information (CSI) obtained by the terminal equipment side based on an AI/ML model or other means are also different.
When uplink channel resources are insufficient, the terminal equipment may omit unimportant bits in the CSI. However, as important bits of the CDI may possibly be more than one groups, the network device is sometimes difficult to determine information on bits omitted by the terminal equipment.
The embodiments of the third aspect provides a method for transmitting channel state information (CSI), applicable to a terminal equipment, such as the terminal equipment 202 in
In operation 501, the at least a portion of information of the first CSI may be, for example, a CSI payload, that is, the CSI payload may be all information of the first CSI, or may be a portion of information of the first CSI.
In the embodiments of the third aspect, the terminal equipment transmits indication information to the network device, so that the network device may expand the received CSI according to the received indication information, thereby facilitating subsequent processing of the terminal equipment.
As shown in
operation 503: the terminal equipment performs omitting processing on second channel state information corresponding to the expanding mode, to form the at least a portion of information of the first channel state information.
In operation 503, the omitting processing is, for example, omitting some bits in the second channel state information (CSI), etc. The second CSI is, for example, output by an AI/ML model at the terminal equipment side, or is generated based on related codebook. A method for generating the second CSI is not limited in this disclosure.
In the embodiments of the third aspect, the terminal equipment performs omitting processing on the second CSI, transmits at least a portion of information of the first CSI obtained by the omitting processing to the network device, and transmits the indication information of the expanding mode to which the omitting processing corresponds to the network device. Hence, the network device may perform expanding processing on the received at least a portion of information of the first CSI (such as padding the bits omitted by the terminal equipment with 0 or 1 or a predetermined bit sequence, such as 10011, etc.), thereby obtaining expanded CSI.
In at least one embodiment, the expanding mode indicated by the indication information includes:
The number and/or positions of the expanded bits may be at least one.
For example, the expanded bits may be located at foremost positions of the at least a portion of information of the first CSI, or may be located at rearmost positions thereof, or may be expanded between two bits (such as being expanded by ai≥0 bits between a pi-th bit and a (pi+1)-th bit, where, i is a positive integer; and these a; may all be identical, or at least two of them are different).
The contents the expanded bits may be at least one.
For example, 0 may be added to all the expanded bits, or 1 may be added to all the expanded bits, or a pre-agreed group of bit sequences may be added to the expanded bits, for example, y=10011 . . . ; however, it is not limited thereto. A length of the added bit sequence is dependent on a sum of all the above ai. For one i, ai bits of sequence y are added to corresponding positions of the at least a portion of information of the first CSI in an order of the sequence y from left to right.
Correspondingly, contents of the omitting processing corresponding to the expanding mode may include:
In at least one embodiment, the expanding mode may be at least one of at least two candidate expanding modes, and the indication information may include an index of the candidate expanding mode, thereby indicating the expanding mode. The at least two candidate expanding modes are predefined, or are configured by the network device.
In at least one embodiment, in at least one piece of channel state information report, the at least a portion of the first channel state information has one layer or at least two layers. In the case where the at least a portion of the first CSI has at least two layers, expanding modes of the layers may be identical, or expanding modes of the at least two layers are different. For example, in the case where it has at least two layers, the layers may have respective indication information indicating expanding modes of the layers, that is, the number of pieces of the indication information may be identical to the number of the layers. For another example, in the case where it has at least two layers, layers with identical expanding modes may share indication information used to indicate an expanding mode.
In at least one embodiments of operation 502, the number and/or positions of bits of resources used to transmit the indication information is/are predefined, or configured by the network device. For example, 3 bits may be used to transmit the indication information, and the bits used to transmit the indication information may be located at the front or rear of the at least a portion of information of the first CSI, or may be located at other predetermined positions.
The method for transmitting channel state information of the third aspect shall be described below by way of examples. In the following embodiments, the number and/or positions of the bits of the resources used to transmit the indication information is/are predefined, or configured by the network device.
Assuming that a CSI uplink channel PUSCH resource configured by the network device is 80 bits, in which 77 bits are used for the CSI payload (i.e. the at least a portion of information of the first CSI), and 3 bits are used for transmitting the indication information, the indication information being used to indicate an expanding mode of the CSI payload. The 3 bits used to indicate the expanding mode are located at last three bits of the 80 bits.
A CSI encoder based on an AI/ML model at the terminal equipment side and a CSI decoder based on an AI/ML model at the network device side have been jointly trained, and output of the encoder and input of the decoder are both 100 bits.
N is a value obtained by subtracting the number of output bits of the encoder by the number of bits of the CSI payload. There are 8 candidate expanding modes for expanding the CSI payload, corresponding to indication information of 3 bits:
In example 1, 0<n<m.
The indication information of 3 bits to which the first to eighth candidate expanding modes respectively correspond may be 000, 001, 010, 011, 100, 101, 110, 111, respectively.
As the uplink resource is 80 bits, in this example, n=23. Before transmitting the CSI payload to the network device via the uplink channel, the terminal equipment selects one of the eight candidate expanding modes as the expanding mode, such as selecting the eighth mode. Hence, according to the selected expanding mode, the terminal equipment omits a 2nd, 4th, 6th, 8th, . . . , 44th and 46th bits for a bit sequence with a length of 100 bits output by the encoder (the bit sequence with a length of 100 bits corresponds to the second CSI), thereby obtaining a bit sequence with a length of 77 bits. The terminal equipment takes “111” as the indication information to indicate the expanding mode, and attaches the bit sequence of 3 bits after the previously obtained bit sequence of 77 bits to obtain a bit sequence of 80 bits. The terminal equipment uploads the bit sequence of 80 bits via an uplink channel (e.g. a PUSCH).
The network device receives the bit sequence of 80 bits, and may learn according to its own specifications that a bit sequence indicating an expanding format exists. The bit sequence is 3 bits in length and is located at the last 3 bits of the 80 bits received by the network device. The network device reads the last 3 bits and obtains 111, hence, the network device learns to use the above candidate expanding mode 8 to extend a sequence of former 77 bits received by the network device. Through the expansion, the network device obtains a bit sequence with a length of 100, and the bit sequence with a length of 100 is input to the decoder, thus, information output by the decoder is recovery of information input to the encoder.
In Implementation 2, as shown in table 6, the indication information used to indicate n expanding mode may be combined with the priority order of the CSI. For example, the information on predetermined bits in the embodiments of the first aspect may be set based on the expanding mode, that is, there may exist a mapping relationship between the priority order and the information on a layer and/or information on bits set according to the expanding mode.
It is assumed that there are three pieces of CSI report, each corresponding to 2 layers. However, this embodiment is not limited thereto, for example, numbers of layers to which at least two pieces of CSI report correspond may be different.
One of the eight candidate expanding modes in Implementation 1 may be selected as a mode for extending the CSI payload (i.e. the at least a portion of information of the first CSI) for each layer. Identical expanding modes may be selected for the layers, or different expanding modes may be selected for at least two layers.
In table 6, the bits reserved according to the selected mode for “expanding a CSI payload” refer to bits reserved in the CSI payload after performing omitting processing by the terminal equipment based on the selected expanding mode.
In table 6, the bits omitted according to the selected mode for “expanding a CSI payload” refer to bits omitted from the second CSI when the terminal equipment performs omitting processing based on the selected expanding mode.
In table 6, indication information used to indicate “a mode for expanding a CSI payload” in the three pieces of CSI reports is set to have a highest priority order, i.e. priority order 0.
In some implementations, the priority order of the CSI may only have one specification, and there exists only one column of mapping relationship in table 6, such as corresponding to #1 or #2.
In some other implementations, the priority order of the CSI may have two specifications, and there exist at least two columns of mapping relationships in table 6, such as corresponding to #1 and #2. The terminal equipment may determine according to configuration of the network device which group of mapping relationships is used to set the priority order of the CSI and omit the CSI; or, the terminal equipment may determine by itself which group of mapping relationships is used to set the priority order of the CSI, omit the CSI, and feed back indices of the group of mapping relationships to the network device. Positions of the indices of the mapping relationships in the feedback bit sequence may be provided in standards or agreed upon in advance by the network device and the terminal equipment.
Implementation 3 is similar to implementation 2.
In implementation 3, all layers in the same CSI report use identical “modes for expanding a CSI payload”.
In implementation 2, each CSI report has 2 layers, and each layer has separate indication information to indicate “a mode for extending a CSI payload”. The indication information is 3 bits, hence, each CSI report needs 6 bits to indicate “a mode for extending a CSI payload”.
In implementation 3, each CSI report has 2 layers, and the two layers may share a piece of indication information to indicate “a mode for extending a CSI payload”. The indication information is 3 bits, hence, each CSI report needs 3 bits to indicate “a mode for extending a CSI payload”. Positions of the 3-bit indication information may be predefined, or may be configured by the network device. For example, the 3 bits may be located after the CSI payload of the first layer or may be located at other positions.
Implementation 4 is similar to implementation 3, with an exception that in implementation 4, different pieces of CSI report may have different numbers of layers.
In implementation 4, as shown in table 7, all layers in the same CSI report use identical “modes for expanding a CSI payload”.
In implementation 4, the indication information of the three pieces of CSI report used to indicate “a mode for extending a CSI payload” is not set to have a highest priority order.
At least a portion of contents of the priority sequence shown in column #1 in table 7 are adjusted, and may be taken as the mapping relationship of #2.
In some implementations, the priority order of the CSI may only have one specification, for example, there exists only one column of mapping relationship in table 7, such as corresponding to #1 or #2.
In some other implementations, the priority order of the CSI may have at least two specifications, for example, there exist at least two columns of mapping relationships in table 7, such as corresponding to #1 and #2. The terminal equipment may determine according to configuration of the network device which group of mapping relationships is used to set the priority order of the CSI and omit the CSI; or, the terminal equipment may determine by itself which group of mapping relationships is used to set the priority order of the CSI, omit the CSI, and feed back indices of the group of mapping relationships to the network device. Positions of the indices of the mapping relationships in the feedback bit sequence may be provided in standards or agreed upon in advance by the network device and the terminal equipment.
