The present disclosure relates to a technical field of communications, and in particular to a wireless communication method and a terminal device.
In a release 17 (R17) of the 3rd Generation Partnership Project (3GPP), a transport block (TB) processing over multi-slot (TBoMS) is considered to be introduced in repeat transmission of PUSCH. That is, a transport block size (TBS) is determined based on multiple slots, or in other words, one TB is transmitted on the multiple slots. However, for a rate matching mechanism in R15/R16, a resource allocating process is only considered to be performed for OFDM symbols in one scheduled slot or a first slot when a rate matching process is performed on a TB. Therefore, the rate matching mechanism in the R15/R16 is not applicable to the TBoMS during multi-slot transmission. In addition, a part of the multiple slots may further be multiplexed to transmit data of a control channel. However, until now, there is still no solution in relation to how to map the data of the control channel in a process of performing the rate matching process on a bit sequence after the TB is encoded.
Therefore, how to achieve the rate matching process for the TBoMS is a technical problem urgent to be solved in the related art.
In a first aspect, the present application provides a wireless communication method including encoding a transport block which is transmitted based on a plurality of time domain unit sets and obtaining a first bit sequence, wherein the plurality of time domain unit sets includes at least one time domain unit set; performing a rate matching process on the first bit sequence based on the plurality of time domain unit sets and obtaining a plurality of second bit sequences respectively corresponding to the plurality of time domain unit sets, wherein a second bit sequence corresponding to each of the at least one time domain unit set includes uplink control information (UCI) multiplexed in the each of the at least one time domain unit set to be transmitted; and modulating and transmitting the plurality of second bit sequences, respectively, based on the plurality of time domain unit sets.
In a second aspect, the present disclosure provides a wireless communication method including receiving a plurality of second bit sequences through a plurality of time domain unit sets, respectively, wherein the plurality of time domain unit sets includes at least one time domain unit set, and a second bit sequence corresponding to each of the at least one time domain unit set includes uplink control information (UCI) multiplexed in the each of the at least one time domain unit set to be transmitted; and decoding the plurality of second bit sequences and obtaining a target transport block.
In a third aspect, the present disclosure provides a terminal device. The terminal device includes a processor and a memory. The memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to perform the method in the above first aspect or various implementations of the first aspect.

It should be understood that terms “system” and “network” are often used interchangeably herein. The term “and/or” is merely a description of an association relationship of associated objects, which may indicate that three relationships may exist. For example, A and/or B indicates three cases, i.e., A existing alone, both A and B existing at the same time, and B existing alone. In addition, the character “/” herein generally indicates that an associated object before “/” and an associated object after “/” are in an “or” relationship.
In order to facilitate understanding the solution provided by the present disclosure, an encoding process of Low Density Parity Check Code (LDPC) is depicted briefly in the following.
In the encoding process of the LDPC, after receiving a TB of MAC, a physical layer first adds 16 or 24 bits of Cyclic Redundancy Check (CRC) to the TB. After the TB is added with the CRC, the TB is required to be divided into two or more code blocks having the same length when the number of bits contained in the TB is greater than a value, and each code block is added with the CRC. Each code block added with the CRC then independently performs a LDPC encoding process. Subsequently, each encoded code block performs a rate matching process, HARQ processing, and interleaving, respectively.
The CRC is a channel coding technique which generates short fixed-bit check code based on data such as network data packet or a computer file, etc. The CRC is configured to detect or check an error which may occurs after data is transmitted or saved. The CRC employs a principle of division and remainder for error detection. The CRC adds (n-k) redundancy bits, i.e., a frame check sequence (FCS), to be after to-be-transmitted data D of k bits, thus, a transmission frame T of n bits is formed. The rate matching refers to bits on a transmission channel being repeated, zero filled, or punctured, to match a carrying capability of a physical channel and reach a bit rate required by a transmission format during channel mapping. In the rate matching process, when the number of input bits is less than the number of output bits, it indicates to be repeated or zero-bit filled. When the number of the input bits is greater than the number of the output bits, it indicates to be punctured. To be repeated means that current bits are inserted once between the current bits and bits thereafter. To be zero-bit filled means that zero bits are inserted between the current bits and bits thereafter. To be punctured means that some bits are punctured according to a specific pattern. That is, some bits are removed or punctured from a bit sequence and simultaneously the following bits are shifted forward by one in turn. A de-rate matching algorithm is opposite to the rate matching process, in which punctured bits are recovered, or repeated bits or zero-filled bits are punctured.
In other words, when an encoded bit sequence is denoted as d1, d2, d3, . . . , dN−1 (N is a length of the encoded sequence), which is input into a circular buffer having a length of Ncb. An output sequence after the rate matching process is denoted as ek, k=0, 1, 2, . . . , E−1. Encoded bits obtained in the rate matching process are interleaved and then modulated, i.e., bit-interleaved coding modulation, which is configured to ensure the performance stability of LDPC codes under a high-order modulation and fading channels. An interleaved sequence is denoted as f1, f2, f3, . . . , fE−1.
When the rate matching process is performed on data of the NR, the encoded bit sequence is multiplexed on resource elements (RE) of a data channel based on the calculated number of REs of the data channel available to transmit the encoded bit sequence. One RE may be one subcarrier with one OFDM symbol, which may be determined based on a parameter such as the number of OFDM symbols in one slot indicated in schedule information (e.g., DCI). As an example, a number of REs may be determined in a following formula:
N
RE=min(156, N′RE)·nPRB;
NRE indicates the number of REs, and nPRB indicates the number of scheduled and allocated RBs. N′RE=NscRB·Nsymbsh−NDMRSPRB−NohPRB, NscRB is the number of subcarriers on each RB, Nsymbsh indicates the number of OFDM symbols in one slot, NDMRSPRB indicates the number of REs occupied by DMRS in each RB, and NohPRB indicates an overhead RE parameter which is configured by a high layer or fixed.
In order to enhance reliability of uplink transmission, NR R15 introduces slot aggregation PUSCH repeat transmission. The slot aggregation PUSCH repeat transmission is illustrated firstly in the following.
The slot aggregation PUSCH repeat transmission means that the same transmission block is repeatedly transmitted for K times with different redundancy versions. In other words, the slot aggregation PUSCH repeat transmission means that a bit sequence mapped in a plurality of actually-repeated slots is a repeat of a single transmission block. The base station configures repetition times K for a terminal through a high-level parameter, i.e., pusch-AggregationFactor. The terminal repeatedly transmits the same TB on K continuous slots. Alternatively, PUSCH copies carrying the TB over the K continuous slots occupy the same symbols in time domain. Alternatively, the K continuous slots employ the same DMRS time domain structure. The RV of the first PUSCH copy is indicated by uplink grant signaling, and RVs of remaining PUSCH copies are cycled in an order of {0,2,3,1}. Transmission of RVs is illustrated in combination with table 1.
As shown in Table 1, the terminal may implement the rate matching process on the TB through a circular buffer. That is, the terminal may store the encoded bits in the circular buffer and sequentially read from the circular buffer based on the RV during each transmission, such that the rate matching process is achieved. In other words, for each transmission, a read position of rate matching is determined by the version number of the RV. Alternatively, the version number of the RV may be configured to indicate which position in this buffer is to extract data from. As an example, four RVs are pre-configured in the circular buffer, i.e., RV0, RV1, RV2, and RV3. A selection order of the four RVs is [0, 2, 3, 1]. That is, RV0 is a starting position of the first transmission, RV2 is a starting position of the second transmission, RV3 is a starting position of the third transmission, and RV1 is a starting position of the fourth transmission. The first transmission refers to the first transmission of data, while the second transmission, the third transmission, and the fourth transmission are all retransmission of data. 0, 2, 3, and 1 are a typical selection order of RVs during data transmission in LTE/NR. 0, 2, 3, and 1 are a value corresponding to the first RV (i.e., RV0), a value corresponding to the third RV (i.e., RV2), a value corresponding to the fourth RV (i.e., RV3), and a value corresponding to the second RV (i.e., RV1), respectively.
In a release 17 (R17) of the 3rd Generation Partnership Project (3GPP), a TBoMS is considered to be introduced in repeat transmission of PUSCH. That is, a transport block size (TBS) is determined based on multiple slots, or in other words, one TB is transmitted on the multiple slots. However, for a rate matching mechanism in R15/R16, a resource allocating process is only considered to be performed for OFDM symbols in one scheduled slot or a first slot when a rate matching process is performed on a TB. Therefore, the rate matching mechanism in the R15/R16 is not applicable to the TBoMS during multi-slot transmission. In addition, a part of the multiple slots may further be multiplexed to transmit data of a control channel. However, until now, there is still no solution in relation to how to map the data of the control channel in a process of performing the rate matching process on a bit sequence after the TB is encoded.
The embodiments of the present disclosure provide a wireless communication method, a terminal device, and a network device, which are not only able to achieve the rate matching process for the TBoMS, but also able to improve receiving and modulating performances of the TB and uplink control information.
As shown in
In an operation S210, the method may include encoding a transport block which is transmitted based on a plurality of time domain unit sets and obtaining a first bit sequence.
In an operation S220, the method may include performing a rate matching process on the first bit sequence based on the plurality of time domain unit sets and obtaining a plurality of second bit sequences respectively corresponding to the plurality of time domain unit sets.
The plurality of time domain unit sets includes at least one time domain unit set, a second bit sequence corresponding to each of the at least one time domain unit set includes uplink control information (UCI) multiplexed in the each of the at least one time domain unit set to be transmitted.
In an operation S230, the method includes modulating and transmitting the plurality of second bit sequences, respectively, based on the plurality of time domain unit sets.
In other words, the transport block (TB) which is transmitted based on the plurality of time domain unit sets is encoded and d1, d2, d3, . . . , dN−1 are obtained. The rate matching process is performed on the first bit sequence based on the plurality of time domain unit sets and ek (k=0, 1, 2, . . . , E−1) respectively corresponding to the plurality of time domain unit sets is obtained. ek is intertwined and then modulated, and then f1, f2, f3, . . . , fE−1 are obtained, i.e., modulated f1, f2, f3, . . . , fE−1 through the plurality of time domain unit sets.
In embodiments of the present disclosure, the TB is transmitted based on the plurality of time domain unit sets, and the rate matching process is performed on the first bit sequence based on the plurality of time domain unit sets. That is, resource allocating process is performed for the first bit sequence based on the plurality of time domain unit sets. Namely, the number of REs available to transmit the first bit sequence may be calculated from a perspective of the plurality of time domain unit sets, such that the number of REs available to transmit the first bit sequence is avoided to be calculated based on a single time domain unit set. Thus, the rate matching process may be ensured to be performed continuously on the first bit sequence. That is, the first bit sequence may be continuously allocated on the plurality of time domain unit sets, which may improve both a power spectral density and a coverage area of the first bit sequence. In this way, the receiving and modulating performance of the TB may be improved.
In addition, after the TB is transmitted based on the plurality of time domain unit sets, transmission positions or transmission resources of bits corresponding to the UCI in the time domain unit sets are required to be determined. In some embodiments of the present disclosure, for each of the at least one time domain unit set, the second bit sequence corresponding to the time domain unit set is constructed to include the UCI which is multiplexed in the time domain unit set to be transmitted. That is, for a time domain unit set in which a multiplexed UCI exists, transmission positions or transmission resources of the bits corresponding to the UCI in the time domain unit set are designed. In this way, the receiving and modulating performance of the UCI may be improved.
In short, on one hand, as the TB is transmitted based on the plurality of time domain unit sets, and the rate matching process is performed on the first bit sequence based on the plurality of time domain unit sets, the receiving and modulating performance of the TB may be improved in some embodiments of the present disclosure. On the other hand, as the second bit sequence corresponding to the time domain unit set is constructed to include the UCI which is multiplexed in the time domain unit set to be transmitted, the receiving and modulating performance of the UCI may be improved in some embodiments of the present disclosure.
It is noted that, when the uplink data channel and the uplink control channel are transmitted on the same time domain unit set, the UCI may be multiplexed on REs of the data channel in a manner of rate matching.
In some embodiments, the operation S220 may include: for a xth time domain unit set of the at least one time domain unit set, determining a second bit sequence corresponding to the xth time domain unit set in a following manner: determining a position offset factor corresponding to the xth time domain unit set; performing a first rate matching process on the first bit sequence based on a version number of a redundancy version (RV) and the position offset factor corresponding to the xth time domain unit set, and determining a starting position of the second bit sequence corresponding to the xth time domain unit set in a circular buffer; performing a second rate matching process on the first bit sequence based on a resource of UCI multiplexed in the xth time domain unit set, and determining an ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer; and obtaining the second bit sequence corresponding to the time domain unit set based on the starting position and the ending position.
In other words, the position offset factor corresponding to the xth time domain unit set is configured to determine the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer, and the resource of the UCI multiplexed in the xth time domain unit set is configured to determine the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. After the starting position and the ending position are obtained, the second bit sequence corresponding to the xth time domain unit set may be read from the circular buffer.
In some embodiments, the position offset factor corresponding to the xth time domain unit set may be determined by the terminal device and the network device themselves. Alternatively, the position offset factor corresponding to the xth time domain unit set is indicated by the network device, or the position offset factor corresponding to the xth time domain unit set is predefined.
It is to be noted that, in the embodiments of the present disclosure, the term “preset” may be implemented by pre-saving corresponding codes, tables, or other manners available to indicate relevant information in a device (e.g., including the terminal device and the network device). A specific implementation manner is not limited in embodiments of the present disclosure. For example, the term “preset” may indicate being defined in a protocol. In some embodiments, the term “protocol” may refer to a standard protocol in the communication field, e.g., including a LTE protocol, a NR protocol, and a relevant protocol in a future communication system, which is not limited in the present disclosure. In addition, it should be understood that the term “indicate” involved in some embodiments of the present disclosure may be indicating directly, or may also be indicating indirectly, or may also be indicating having a relevant relationship. For example, A indicating B may present that A directly indicates B, for example, B may be acquired through A. A indicating B may also present that A indirectly indicates B, for example, A indicates C, and B may be acquired through C. A indicating B may also present that a relevant relationship may exist between A and B.
In some embodiments, the terminal device performs the second rate matching process on the first bit sequence based on the number of REs available to transmit the first bit sequence in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. In other words, the number of REs of the multiplexed UCI is not configured for the rate matching process on the first bit sequence. That is, during the rate matching process on the first bit sequence, a transmission resource is reserved for the multiplexed UCI in the xth time domain unit set.
As an example, the terminal device determines the number of REs available to transmit the multiplexed UCI in the xth time domain unit set. The terminal device determines the number of REs available to transmit the first bit sequence based on the number of the REs available to transmit the multiplexed UCI and the number of REs allocated for transmitting the TB in the xth time domain unit set. The terminal device performs the second rate matching process on the first bit sequence based on the number of the REs available to transmit the first bit sequence, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer.
In some embodiments, the number of REs available to transmit the multiplexed UCI is determined in a following formula:
S
1
=S
2
*C;
S1 indicates the number of the REs available to transmit the multiplexed UCI, S2 indicates the number of REs allocated for transmitting the TB, and C indicates a beta coefficient.
As an example, the terminal device determines the number of REs available for data transmission in the xth time domain unit set. The terminal device performs the second rate matching process on the first bit sequence based on the number of REs allocated for transmitting the TB, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. A part of data bits in the second bit sequence corresponding to the xth time domain unit set is replaced with a part or all of information in the UCI multiplexed in the xth time domain unit set to be transmitted.
In some embodiments, the terminal device determines the number of REs allocated for transmitting the TB in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer based on the number of REs allocated for transmitting the TB. In other words, the number of REs of the multiplexed UCI is configured for the rate matching process on the first bit sequence. That is, when the rate matching process is performed on the first bit sequence, no transmission resource is reserved for the multiplexed UCI in the xth time domain unit set. Based on this, after the rate matching process on the first bit sequence is completed, the part of data bits in the second bit sequence corresponding to the xth time domain unit set is replaced with the part or all of information in the UCI multiplexed in the xth time domain unit set to be transmitted.
Of course, the part of data bits in the second bit sequence corresponding to the xth time domain unit set is replaced with the part of information in the UCI multiplexed in the xth time domain unit set to be transmitted, the other part of information in the UCI multiplexed in the xth time domain unit set to be transmitted may be discarded. Alternatively, during the rate matching process on the first bit sequence, a transmission resource is reserved for the other part of information in the xth time domain unit set, which is not limited in some embodiments of the present disclosure.
In other words, the number of bits available to transmit the multiplexed UCI may be determined in a following formula:
S
3
=S
4
*C;
S3 indicates the number of bits available to transmit the multiplexed UCI, S4 indicates the number of transmittable bits in the first bit sequence, and C indicates the beta coefficient. In an embodiment, S3 may be determined based on S2 and a modulation order. In some embodiments, the beta coefficient may be a parameter semi-statically configured by a high-layer parameter, or may also be a dynamically-configured parameter, which is not limited in embodiments of the present disclosure.
In some embodiments, the position offset factor corresponding to the xth time domain unit set is determined based on the version number of the RV and an ending position of a second bit sequence corresponding to a (x−1)th time domain unit set of the plurality of the time domain unit sets in the circular buffer.
In other words, a starting position of a current time domain unit set in the circular buffer is determined based on an ending position of a second bit sequence corresponding to a previous time domain unit set in the circular buffer. That is, the starting position of the current time domain unit set in the circular buffer is influenced by the ending position of the second bit sequence corresponding to the previous time domain unit set in the circular buffer.
In some embodiments, the position offset factor corresponding to the xth time domain unit set is determined as the total number of bits occupied by second bit sequences corresponding to all time domain unit sets prior to the xth time domain unit set in the circular buffer.
In other words, the starting position of the current time domain unit set in the circular buffer is determined based on the total number of bits occupied by the second bit sequence corresponding to the previous time domain unit set in the circular buffer. That is, the starting position of the current time domain unit set in the circular buffer is influenced by the total number of bits occupied by the second bit sequence corresponding to the previous time domain unit set in the circular buffer.
As an example, the position offset factor corresponding to the xth time domain unit set may be determined in a following formula:
Ox indicates the position offset factor corresponding to the xth time domain unit set, and di indicates the number of bits occupied by a second bit sequence corresponding to an ith time domain unit set of the plurality of time domain unit sets in the circular buffer.
In some embodiments, the position offset factor corresponding to the xth time domain unit set is determined as the total number of transmittable bits in all time domain unit sets prior to the xth time domain unit set.
In other words, the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer may be determined based on the version number of the RV and the total number of transmittable bits in all time domain unit sets prior to the xth time domain unit set. That is, the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer is influenced by the number of bits occupied by second bit sequences corresponding to other time domain unit sets in the circular buffer.
As an example, the position offset factor corresponding to the xth time domain unit set is determined in a following formula:
Ox indicates the position offset factor corresponding to the xth time domain unit set, and ti indicates the number of transmittable bits in the ith time domain unit set of the plurality of time domain unit sets.
In some embodiments, the method 200 may further include determining the number of transmittable bits in each time domain unit set of the plurality of time domain unit sets in the following manner: determining a total number of REs available for uplink transmission on the each time domain unit set according to a time-frequency resource corresponding to the each time domain unit set; and determining the number of transmittable bits in the each time domain unit set based on the number of the REs available for the uplink transmission in the each time domain unit set and the modulation order.
In other words, the terminal device first determines the total number of the REs available for the uplink transmission in a time domain unit set according to a time-frequency resource corresponding to the time domain unit set. The terminal device then determines the number of transmittable bits in the time domain unit set based on the number of the REs available for the uplink transmission in the time domain unit set and a modulation order. Subsequently, the total number of the transmittable bits in all time domain unit sets prior to the xth time domain unit set is determined to be the position offset factor corresponding to the xth time domain unit set.
In some embodiments, the time domain unit set only includes one time domain unit, or the time domain unit set includes at least one continuous time domain unit. The time domain unit includes a slot or a symbol.
The solution of the present disclosure is described in combination with some embodiments in the following.
In this embodiment, the terminal device determines the total number of the bits occupied by the second bit sequences corresponding to all time domain unit sets prior to the xth time domain unit set of the plurality of the time domain unit sets in the circular buffer to be the position offset factor corresponding to the xth time domain unit set.
As shown in
In other words, the terminal device processes the first bit sequence to a plurality of second bit sequences based on rate matching.
A processing process may refer to the following steps 1-3.
At step 1, the terminal device first determines the total number of the bits occupied by the second bit sequences corresponding to all time domain unit sets prior to the xth time domain unit set in the circular buffer to be the position offset factor corresponding to the xth time domain unit set. The terminal device then performs the first rate matching process on the first bit sequence based on the version number of the RV and the position offset factor corresponding to the xth time domain unit set, and determines the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer.
As an example, the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer is added by the version number of the RV (e.g., the version number of the RV is equal to 0 in
In some embodiments, when x>1, OFFSET is equal to data bits determined through the first rate matching process and the second data matching process in the (x−1)th time domain unit set. When x=1, OFFSET=0.
At step 2, the terminal device performs the second rate matching process on the first bit sequence based on the resource of the UCI multiplexed in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer.
As an example, the terminal device first determines the number of the REs available to transmit the multiplexed UCI in the xth time domain unit set, and then determines the number of the REs available to transmit the first bit sequence based on the number of the REs available to transmit the multiplexed UCI and the number of the REs allocated for transmitting the TB in the xth time domain unit set. Subsequently, the terminal device performs the second rate matching process on the first bit sequence based on the number of the REs available to transmit the first bit sequence and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. In some embodiments, the terminal device may determine the number of the REs available to transmit the multiplexed UCI based on the number of REs allocated for transmitting the TB and the beta coefficient. For example, the number of the REs available to transmit the multiplexed UCI=the number of the REs configured to transmit the first bit sequence×the beta coefficient. Of course, in other alternative embodiments, the terminal device may perform the second rate matching process on the first bit sequence based on the number of REs allocated for transmitting the TB after determining the number of the REs allocated for transmitting the TB in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. In this case, a part of information of the multiplexed UCI is replaced into the second bit sequence corresponding to the xth time domain unit set through a manner of puncturing a part of data bits of the second bit sequence corresponding to the xth time domain unit set. In other words, the data bits which are punctured and removed are considered into the rate matching. That is, punctured data is counted into the OFFSET.
It is noted that, one TB may include one or more code blocks (CB). When the first rate matching process is performed on the first bit sequence, a scope of the rate matching process is performed on a CB-by-CB basis. That is, each CB uses an independent circular buffer.
At step 3, the plurality of the second bit sequences is modulated and transmitted, respectively, on the plurality of the time domain unit sets.
In this embodiment, the terminal device determines the total number of the transmittable bits in all time domain unit sets prior to the xth time domain unit set to be the position offset factor corresponding to the xth time domain unit set.

In other words, the terminal device processes the first bit sequence to the plurality of second bit sequences based on rate matching.
A processing process may refer to the following steps 1-3.
At Step 1, the terminal device first determines the total number of the bits occupied by the second bit sequences corresponding to all time domain unit sets prior to the xth time domain unit set in the circular buffer to be the position offset factor corresponding to the xth time domain unit set. The terminal device then performs the first rate matching process on the first bit sequence based on the version number of the RV and the position offset factor corresponding to the xth time domain unit set, and determines the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer.
As an example, the starting position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer is added by the version number of the RV (e.g., the version number of the RV is equal to 0 in
In some embodiments, when x>1, OFFSET is equal to the data bits determined through the first rate matching process in the (x−1)th time domain unit set. When x=1, OFFSET=0.
At Step 2, the terminal device performs the second rate matching process on the first bit sequence based on the resource of the UCI multiplexed in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer.
As an example, the terminal device first determines the number of the REs available to transmit the multiplexed UCI in the xth time domain unit set, and then determines the number of the REs available to transmit the first bit sequence based on the number of the REs available to transmit the multiplexed UCI and the number of the REs allocated for transmitting the TB in the xth time domain unit set. Subsequently, the terminal device performs the second rate matching process on the first bit sequence based on the number of the REs available to transmit the first bit sequence and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. In some embodiments, the terminal device may determine the number of the REs available to transmit the multiplexed UCI based on the number of REs allocated for transmitting the TB and the beta coefficient. For example, the number of the REs available to transmit the multiplexed UCI=the number of the REs configured to transmit the first bit sequence×the beta coefficient. Of course, in other alternative embodiments, the terminal device may perform the second rate matching process on the first bit sequence based on the number of REs allocated for transmitting the TB after determining the number of the REs allocated for transmitting the TB in the xth time domain unit set, and determines the ending position of the second bit sequence corresponding to the xth time domain unit set in the circular buffer. In this case, the part of information of the multiplexed UCI is replaced into the second bit sequence corresponding to the xth time domain unit set through the manner of puncturing the part of data bits of the second bit sequence corresponding to the xth time domain unit set. In other words, the data bits which are punctured and removed are considered into the rate matching. That is, the punctured data is counted into the OFFSET.
It is noted that, one TB may include one or more code blocks (CB). When the first rate matching process is performed for the first bit sequence, the scope of the rate matching process is performed on a CB-by-CB basis. That is, each CB uses an independent circular buffer.
At Step 3, the plurality of the second bit sequences is modulated and transmitted, respectively, on the plurality of the time domain unit sets.
It is noted that, a difference between the Embodiment 1 and the Embodiment 2 lies in the step 1. The position offset factor in the Embodiment 1 is influenced by the first rate matching process and the second rate matching process which is performed on the first bit sequence based on all time domain unit sets prior to the Xth time domain unit seton the first bit sequence. The first rate matching process indicates a process of mapping the PUSCH or the first bit sequence to the plurality of time domain unit sets. The second rate matching process indicates a process of mapping the UCI to the plurality of time domain unit sets. In the Embodiment 2, the first rate matching process is firstly preformed on all time domain unit sets, and the second rate matching process is performed on each time domain unit set, respectively. Second rate matching processes for different time domain unit sets are mutually un-influenced.
In addition, it should be understood that the TB involved in embodiments of the present disclosure may be the PUSCH TB, and control information may be the PUCCH. Of course, the TB may be other types of TBs, or the control information may be replaced with other channels, which is not limited in embodiments of the present disclosure. For example, the control information may be also replaced with a pilot frequency signal. Based on this, these channels may be allowed to better repeatedly utilize time domain resources, which further enhances a performance of effective channel coverage.
