The terminal involved in the embodiments of the present disclosure may be a device that provides voice and/or data connectivity to a user, a handheld device with a radio connection function, or other processing devices connected to a radio modem or the like. In different systems, the names of terminal devices may be different. For example, in a 5G system, a terminal device may be called user equipment (UE). Wireless terminal device can communicate with one or more core networks (CNs) via a radio access network (RAN), and wireless terminal device may be mobile terminal device, such as mobile phones (or called “cellular” phones) and computers with mobile terminal device, such as portable, pocket-sized, hand-held, computer built-in or vehicle-mounted mobile apparatuses, which exchange voice and/or data with the radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistant (PDA), Redcap terminal and other devices. The wireless terminal device may also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, and user device, which are not limited in the embodiments of the present disclosure.
The network device involved in the embodiments of the present disclosure may be a base station. The base station may include multiple cells that provide services to terminals. Depending on the specific application scenario, the base station may be called access point, or may be a device in the access network that communicates over an air interface with wireless terminal devices through one or more sectors, or may be called other name. The network device may be used for converting the received radio frames into Internet protocol (IP) packets or vice versa, and serves as a router between the wireless terminal devices and the rest of the access network. The rest of the access network may include an IP communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the global system for mobile communications (GSM) or code division multiple access (CDMA), a NodeB in the wide-band code division multiple access (WCDMA), an evolved Node B (eNB or e-NodeB) in Long Term Evolution (LTE) system, a 5G base station (gNB) in 5G network architecture (next generation system), a base station in 6G, a home evolved Node B (HeNB), a relay node, a femto, a pico, or the like, which is not limited herein. In some network architectures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, which may be located geographically separated.
The network device and the terminal device may each perform multi-input multi-output (MIMO) transmission with each other by using one or more antennas. The MIMO transmission may be single user MIMO (SU-MIMO) or multiple user MIMO (MU-MIMO). According to the configuration and quantity of antenna combinations, the MIMO transmission may be two dimensional-MIMO (2D-MIMO), three dimensional-MIMO (3D-MIMO), full dimensional-MIMO (FD-MIMO) or massive-MIMO, and may be diversity transmission, precoded transmission, beam forming transmission, or the like.
The first information and the second information may be transmitted simultaneously, or may be transmitted at different timings, for example, the first information is transmitted first, and then the second information is transmitted, alternatively, the first information and the second information may be transmitted in cascade, the present disclosure is not limited thereto.
The first partial user information and the second partial user information are two parts of the same information. For example, the first p bits ωp of one piece of information are taken as the first partial user information, and the remaining c (the total bit count minus p) bits ωc are taken as the second partial user information, p>0.
The first processing may be coding, e.g., a first joint coding, such as compressive sensing coding, ZC sequence mapping or linear block coding. With the compressive sensing coding, excellent decoding performance can be achieved, and it can be used for assisting the decoding of other user information, for example, assisting the decoding of other user information with a code rate of 0.1 or encoded with a newer linear block coding.
The first processing is not limited in the embodiments of the present disclosure, for example, the first processing may be coding the control information of the second partial user information and the first partial user information respectively, and concatenating the coding results, or the first processing may be other processing such as compressing the control information of the second partial user information and the first partial user information.
The second processing may be coding, e.g., channel coding, specifically, the second processing may be coding such as low density parity check code (LDPC) coding or Polar coding. The second processing is not limited in the embodiments of the present disclosure, for example, the second processing may be other processing such as compressing.
That the parameter of the second information is determined according to the control information of the second partial user information and/or the first partial user information may refer to that the parameter of the second information is determined according to at least one of: the control information of the second partial user information, or the first partial user information. For example, a processing is performed on at least one of: the control information of the second partial user information, or the first partial user information, and then the parameter of the second information is determined according to information derived from the processing, e.g., a result of the processing and the first information have a corresponding relationship, and thus the parameter of the second information can be determined according to the corresponding relationship.
In embodiment of the present disclosure, it can be achieved through the aforementioned steps that the second information is information obtained by performing the second processing on the second partial user information, and the parameter of the second information is determined according to the control information of the second partial user information and the first partial user information. In this way, there is no need to configure the parameter of the second information for each terminal individually, thereby resource consumption is reduced.
As an optional implementation, the first partial user information is first partial information in an information combination, and the information combination is a combination of user identity information and user data.
The information combination may be a combination of bits of user identity information and user data.
In this implementation, since the first partial user information is the first partial information in the information combination, a probability that the first partial information of one terminal coincides with the first partial information of another terminal may be reduced, or the first partial user information of different terminals may be prevented from coinciding with one another, such that the parameters of the second information of different terminals differ from one another, thereby effectively reducing inter-terminal interference.
In addition, the length of the first partial user information may correspond to the maximum quantity of active users that the system is capable of accommodate. For example, the first p bits ωp of the information combination (identity information+data) are taken as the first partial user information, and the remaining c (the total bit count minus p) bits ωc are taken as the second partial user information, wherein the value of p (which is greater than 0) is determined by the maximum quantity of active users that the system is capable of accommodate. When the quantity of users is enormous, the value of p should be large, whereby the diversity of transmitting occasions can be achieved through a processing on ωp, and the possibility that different users use identical transmitting occasions is minimized; when the quantity of users is small, the value of p should be small, so as to ensure that the target performance of ωp may be achieved with less resources.
As an optional implementation, the control information of the second partial user information includes at least one of: a quantity of repeated transmissions K, resources for repeated transmissions, or a data format of repeated transmissions.
The control information may be configured by the network side for the terminal, or may be determined by the terminal by itself. For example, the terminal determines the control information according to a result of measuring a reference signal. Specifically, the terminal may measure a synchronization signal block (SSB) or channel state information reference signal (CSI-RS) to obtain synchronization signal reference signal received power (SS-RSRP), synchronization signal reference signal received quality (SS-RSRQ), synchronization signal signal to interference plus noise ratio (SS-SINR), channel state information (CSI) or the like, and determine the control information according to these measurement results.
As an optional implementation, the parameter of the second information includes at least one of: the data format of repeated transmissions, an interleaving mode or K data transmitting occasions, K being equal to the quantity of repeated transmissions.
In this implementation, it may be achieved that at least one of the interleaving mode or the K data transmitting occasions is determined according to the data format of repeated transmissions of the first information. Thus, there is no need to configure the data format of repeated transmissions, the interleaving mode and the K data transmitting occasions for terminals, thereby resource consumption is reduced.
In addition, in this implementation, at least one of the interleaving mode or the K data transmitting occasions may be determined using some or all contents of the control information of the second partial user information and the first partial user information. For example, a through-coding (e.g., linear block coding) is performed on all or some information of the control information of the second partial user information and the first partial user information, and the information derived from the coding represents the interleaving mode. For example, a value of the information derived from the coding (e.g., a codeword outputted by a linear block coding) is equivalent to an index, and the index corresponds to an interleaving mode, e.g., the initial read-out position of an interleaver inputting row-wise and outputting column-wise is determined by the index.
For another example, a through-coding is performed on all or some information of the control information of the second partial user information and the first partial user information, the output of the coding is greater than K bits, and these bits indicate K data transmitting occasions.
In addition, in this implementation, one or more interleaving modes may be encompassed. The coding of the K data transmitting occasions may adopt the same interleaving mode, or different interleaving modes.
As an optional implementation, the second partial user information is second partial information in an information combination, and the information combination is a combination of user identity information and user data.
The information combination may be a combination of bits of user identity information and user data. Additionally, the second partial user information may be information bits other than the first partial user information in the information combination.
In this implementation, since the second partial user information is the second partial information in the information combination, user identity information and user data may be transmitted through the first information and second information to the network device effectively, thereby improving transmission performance of the terminal.
As an optional implementation, the first processing includes a first joint coding; and the first processing further includes at least one of: scrambling prior to the first joint coding, adding a cyclic redundancy check (CRC) code prior to the first joint coding, puncturing prior to the first joint coding, or setting a redundancy version (RV) subsequent to the first joint coding.
In this implementation, it may be achieved that the control information of the second partial user information and the first partial user information are scrambled and further added with a CRC code before the first joint coding. In this way, the transmission reliability of the first information is improved.
Further, since puncturing and RV setting may be performed after the first joint coding, the transmission performance of the first information may be further improved.
As an optional implementation, coding control information of the second partial user information is determined according to third information, and the third information is obtained by performing a third processing on the control information of the second partial user information and/or the first partial user information.
The coding control information of the second partial user information may be related information for controlling the coding of the second partial information, e.g., control information such as interleaving mode or code rate.
The third processing may be coding, e.g., a second joint coding. The second joint coding may be different from the aforementioned first joint coding, e.g., the first joint coding and the second joint coding utilize different encoders. Of course, the second joint coding may be the same as the first joint coding in some scenarios. For example, the second joint coding may be compressive sensing coding, ZC sequence mapping, linear block coding, or the like.
That the coding control information of the second partial user information is determined according to third information may refer to that the third information and the coding control information have a corresponding relationship, and the coding control information is determined according to the corresponding relationship.
Optionally, the K data transmitting occasions are determined according to fourth information, and the fourth information is obtained by performing a fourth processing on the control information of the second partial user information and/or the first partial user information.
The fourth processing may be coding, e.g., a third joint coding. The third joint coding may be different from the aforementioned first joint coding and second joint coding, e.g., the first joint coding, the second joint coding and the third joint coding utilize different encoders. Of course, the third joint coding may be identical to the first joint coding and/or the second joint coding in some scenarios. For example, the third joint coding may be compressive sensing coding, ZC sequence mapping, linear block coding, or the like.
That the K data transmitting occasions are determined according to fourth information may refer to that the K data transmitting occasions are indicated by the fourth information.
Optionally, the fourth information is a quantity J of resources used by the terminal for transmission, J being greater than or equal to K, and the fourth information is used for indicating that K resources in the J resources are the K data transmitting occasions.
Through values of bits, the fourth information may indicate that K resources in the J resources are the K data transmitting occasions. For example, the fourth information includes J bits, and each bit corresponds to one resource. Thus, through the values of the J bits, K resources are indicated as K data transmitting occasions. Additionally, the J resources may be pre-configured.
For example, there are J slots in total for the terminal to transmit data, the length of the codeword outputted by the third joint coding is J, and J bits are used for indicating whether each transmitting occasion is used, wherein 1 indicates the transmitting occasion is used, and 0 indicates the transmitting occasion is not used. Then K bits in the J bits of the fourth information are 1, while the remaining bits are 0. Exactly which K bits are 1 is determined by the control information of the second partial user information and the first partial user information, so as to achieve the randomization of transmitting occasions, thereby reducing inter-terminal interference.
As an optional implementation, the transmitting, by the terminal, the second information to the network device includes: transmitting, by the terminal, the second information to the network device once or K times.
The transmitting the second information once may refer to transmitting the second information once in the case that K repeated transmissions are not configured. Of course, in some scenarios, even if K repeated transmissions are configured, K pieces of second information may be concatenated to be transmitted once, wherein the single transmission includes the K pieces of second information.
The transmitting the second information K times may refer to transmitting second information in K data transmitting occasions respectively.
It is noted, in the case that the second information is transmitted K times, the first information may be transmitted once or K times.
As an optional implementation, the method further includes: receiving, by the terminal, access configuration information transmitted by the network device, wherein the access configuration information is used for transmitting at least one of the first information or the second information.
The access configuration information may be massive access configuration information of a cell. The access configuration information may specifically include at least one of: cell configuration information, broadcast information, multicast information, access frame location information, resource location, starting location, resource length, or the like.
In this implementation, since the access configuration information is received, the first information and the second information may be transmitted according to the access configuration information, such that the network device may rapidly receive the first information and the second information.
It is noted, the access configuration information may also be pre-configured.
In the embodiments of the present disclosure, the terminal transmits first information and second information to the network device; wherein the first information is obtained by performing a first processing on control information of second partial user information and first partial user information; the second information is information obtained by performing a second processing on the second partial user information, and a parameter of the second information is determined according to the control information of the second partial user information and/or the first partial user information. In this way, since the second information is information obtained by performing the second processing on the second partial user information, and the parameter of the second information is determined according to the control information of the second partial user information and the first partial user information, resource consumption can be reduced.
The obtaining, according to the first information, the control information of second partial user information and the first partial user information may be performing an inverse operation of the first processing on the first information, e.g., performing decoding to obtain the control information of second partial user information and the first partial user information.
The receiving, according to the control information of the second partial user information and the first partial user information, second information transmitted by the terminal may be determining the parameter of the second information according to the control information of the second partial user information and the first partial user information, receiving, according to the parameter, the second information transmitted by the terminal, and then obtaining the second partial information through an inverse operation of the second processing.
Optionally, the first partial user information is first partial information in an information combination, the information combination being a combination of user identity information and user data.
Optionally, the control information of the second partial user information includes at least one of: a quantity of repeated transmissions K, resources for repeated transmissions, or a data format of repeated transmissions;
Optionally, the second partial user information is second partial information in an information combination, the information combination being a combination of user identity information and user data.
Optionally, the first processing includes a first joint coding; and the first processing further includes at least one of: scrambling prior to the first joint coding, adding a cyclic redundancy check (CRC) code prior to the first joint coding, puncturing prior to the first joint coding, or setting a redundancy version (RV) subsequent to the first joint coding.
Optionally, coding control information of the second partial user information is determined according to third information, and the third information is obtained by performing a third processing on the control information of the second partial user information and/or the first partial user information.

Optionally, the fourth information is a quantity J of resources used by the terminal for transmission, J being greater than or equal to K, and the fourth information is used for indicating that K resources in the J resources are the K data transmitting occasions.
Optionally, the method further includes: transmitting, by the network device, access configuration information to the terminal, wherein the access configuration information is used for transmitting at least one of the first information or the second information.
It is noted, this embodiment is an implementation of the corresponding network device in the embodiment shown in
The method provided in the embodiments of the present disclosure is described by way of example through the following embodiments.
The terminal side behavior is described in this embodiment, and may specifically include the following steps 1 to 12.
Step 1: through a cell search process, downlink synchronization of the terminal is achieved, and the terminal obtains access configuration information.
Step 2: if uplink time synchronization information such as timing advance (TA) can be obtained, the terminal records or updates TA information.
Step 3: the terminal measures SSB/CSI-RS to obtain SS-RSRP/SS-RSRQ/SS-SINR/CSI or the like, and determines a quantity of repeated transmissions K.
If taking determining K based on SS-RSRQ measurements as an example, the step may include:
Step 4: the terminal takes the first p bits ωp of the user information (identity information+data) as the first partial user information, and takes the remaining c (the total bit count minus p) bits ωc as the second partial user information, wherein the value of p (which is greater than 0) is determined by the maximum quantity of active users that the system is capable of accommodate. When the quantity of users is enormous, the value of p should be large, whereby the diversity of transmitting occasions can be achieved through the coding of ωp and the possibility that different users use identical transmitting occasions is minimized; when the quantity of users is small, the value of p should be small, so as to ensure that the target performance of ωp may be achieved with less resources.
Step 5: the terminal performs channel coding (e.g., LDPC coding, Polar coding, etc.) on the ωc second partial user information.
Step 6: the terminal performs joint coding 1 on the quantity of repeated transmissions K and the ωp first partial user information, to determine the interleaving mode of channel coding, and performs interleaving on the output of the channel coding of oc.
Step 7: the terminal performs joint coding 2 on the quantity of repeated transmissions K and the ωp first partial user information, to determine K data transmitting occasions in one time interval (e.g., one frame) configured by the network.
Step 8: the terminal performs joint coding 3 on the quantity of repeated transmissions K and the ωp first partial user information, to obtain the first information. The step may utilize compressive sensing coding, ZC sequence mapping, linear block coding or the like.
Step 9: the terminal performs pre-processing such as modulation on the encoded (or interleaved) data obtained in the step 5 and step 8; the pre-processing includes at least one of MIMO pre-coding, beam forming, power adjustment or the like.
Step 10: the terminal maps the pre-process data of the quantity of repeated transmissions K and the ωp first partial user information to a starting position (according to TA) in one time interval for transmission.
Step 11: the terminal maps the pre-process data of the ωc second partial user information to the K data transmitting occasions determined in the step 7 for transmission.
Step 12: the terminal waits for the base station's response; if an acknowledgement message is not received within a predetermined time window, the terminal retransmits, and if the acknowledgement message is received, the transmission process ends.
It is noted, the steps 1, 2, 3, 6, 7 and 9 are optional in this embodiment.
The network device side behavior is described in this embodiment, and may specifically include the following steps 1 to 9.
Step 1: the network device broadcasts/unicasts access configuration information in the cell.
Step 2: the network device detects, at the access resource positions corresponding to the configured access configuration information, the first information resulting from the joint coding 3 of the quantity of repeated transmissions K and the ωp first partial user information. Specifically, a non-coherence detection may be performed; the detection of joint coding 3 through non-coherence detection may be performing correlation operation on all possible coding sequences one by one, and the information sequence corresponding to Ka coding sequences with the largest correlation values is the K and ωp.
Step 3: the network device obtains the quantity of repeated transmissions K and the ωp first partial user information according to the decoded output of the step 2.
Step 4: the network device performs joint coding 1 on the quantity of repeated transmissions K and the ωp first partial user information, to obtain K data transmitting occasions in one time interval.
Step 5: the network device performs joint coding 2 on the quantity of repeated transmissions K and the ωp first partial user information, to obtain the interleaving mode of channel coding of the ωc second partial information.
Step 6: the network device obtains, using the information of step 4 and step 5 and through iterative decoding and the like, a certain terminal's ωc second partial information.
The LDPC decoding may be joint decoding of K repeated transmissions.
Step 7: the network device performs a joint CRC check on the ωp first partial user information and the ωc second partial information; if the CRC check is passed, the network device may perform an interference cancellation operation. As shown in
The CRC check may be performed on ωc, ω=(ωp, ωc), (K, ω), or other combination of K, ωp, ωc.
Step 8: the network device performs the steps 6 and 7 cyclically, to obtain user information of all terminals.
Step 9: the network device transmits an acknowledgement message within a predetermined time window (which is the same as the window on the terminal side) to the terminal passing the CRC check.
It is noted, the steps 1, 4, 5, 7, 8 and 9 are optional in this embodiment.
In the embodiments of the present disclosure, the following may be achieved.
When multiple terminals share a channel, with the introduction of different occupancy time lengths and different occupancy time positions, wherein the occupancy time lengths and different occupancy time positions may be through the control information of the second partial user information and the first partial user information, inter-terminal interference can be reduced effectively, and the detection performance of individual terminal may be improved effectively, while the performance of interference cancellation receiver is improved, that is, the joint detection performance of multiple terminals may be improved. The improvement of interference cancellation performance refers to that different terminals occupy different transmitting occasions, and if the quantity of terminals transmitting simultaneously is small on some transmitting occasions, the detection succeeds relatively easily, then the data of the terminal detected successfully may be deleted from other transmitting occasions, thereby reducing its interference. The solution of contributing transmitting occasions in a possibly staggered manner improves the effect of interference cancellation. If the detection succeeds, the interference cancellation is achieved.
