Description

Uplink communication method, device and storage medium

Technical Field

Background

With the development of communication technology, in order to support higher transmission rate and throughput rate for uplink, a method of increasing the number of transmission antennas is adopted. For example, current protocol version studies enhance the number of transmit antennas to 8 antennas for the uplink.

In the related art, a fixed transport block to codeword mapping is employed. For the case where the number of layers (rank) is less than or equal to 4, one codeword is used. For the case that rank exceeds 4, two codewords are used. Currently, in physical uplink shared channel (physical uplink shared channel, PUSCH) transmission, the number of transmit antennas is considered to be increased to 8 antennas. Thus, PUSCH transmissions support uplink transmissions of a maximum of 8 layers, i.e. support the use of multiple codeword to layer mappings.

Among them, an implementation of uplink communication using a multi-codeword to layer mapping method is being studied to improve transmission quality. However, the configuration of multiple codewords in uplink PUSCH transmission for multiple codewords is still under study.

The wireless communication system may employ different communication techniques such as code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency-Division Multiple Access, OFDMA), single Carrier frequency division multiple access (SC-FDMA), carrier sense multiple access/collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). Networks may be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as a fifth Generation wireless communication system (The 5th Generation Wireless Communication System,5G) network, and 5G networks may also be referred to as New Radio (NR) networks, according to factors such as capacity, rate, delay, etc. of different networks. For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved Node B (eNB), a home base station, an Access Point (AP) in a wireless fidelity (Wireless Fidelity, WIFI) system, a wireless relay Node, a wireless backhaul Node, or a transmission Point (Transmission Point, TP), etc., or may be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. In the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited.

Further, a Terminal referred to in the present disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and may be a device that provides voice and/or data connectivity to a User, for example, a handheld device, an in-vehicle device, or the like that has a wireless connection function.

In the embodiment of the disclosure, any feasible wireless communication technology can be adopted by the network device and the terminal to realize mutual data transmission. The transmission channel corresponding to the data sent by the network device to the terminal is called a Downlink (DL) channel, and the transmission channel corresponding to the data sent by the terminal to the network device is called an Uplink (UL) channel. It is to be appreciated that the network devices involved in embodiments of the present disclosure may be base stations. Of course, the network device may be any other possible network device, and the terminal may be any possible terminal, which is not limited by the present disclosure.

Wherein, the related art terminal and the network device perform transmission and perform codeword-to-layer (rank) mapping by adopting a fixed mapping sequence of transmission blocks to codewords. For the case where rank is less than or equal to 4, one codeword is used. For the case that rank exceeds 4, two codewords are used. Currently, the downlink can support a maximum of 2 codewords, while the uplink supports 1 codeword.

Fig. 2 illustrates a codeword to layer mapping scheme in accordance with an exemplary embodiment.

As shown in fig. 2, the mapping manner of CodeWord (CW) to layer in the current physical downlink control channel (physical downlink shared channel, PDSCH) transmission is shown. Where CW0 represents a first codeword and CW1 represents a second codeword. When the number of layers (rank) is less than or equal to 4, one codeword CW0 is correspondingly used. When rank exceeds 4, two codewords are correspondingly used, CW0 and CW1, respectively. For the case of transmission using two codewords, the codeword-to-layer mapping adopts a mapping mode which is as balanced as possible, when the rank is odd, the number of layers of the CW0 mapping is one layer less than that of the CW1 mapping, and when the rank is even, the number of layers of the CW0 mapping is consistent with that of the CW1 mapping.

Wherein table 1 shows a codeword to layer mapping scheme.

TABLE 1

Table 1 shows a mapping scheme of space division multiplexing codewords to layers, with different complex-valued modulation symbols mapped to different data layers for different layers, respectively. Wherein layer represents a data layer, symbol represents a symbol,

It can be seen from table 1 that there is only one codeword, and that when the first codeword CW0 is mapped to 4 layers,

complex-valued modulation symbols are equally distributed to 4 layers; when two codewords exist and are mapped to 8 layers, the complex-valued modulation symbols of the first codeword CW0 and the second codeword CW1 are equal, i.e. +. >

Are all equal.

In order to support higher transmission rate and throughput rate for the uplink, a manner of increasing the number of transmit antennas is adopted. For example, current protocol version studies enhance the number of transmit antennas to 8 antennas for the uplink.

Currently, the physical uplink shared channel (physical uplink shared channel, PUSCH) transmission supports a transmission with a maximum rank equal to 4, and the number of corresponding supported maximum codewords is one. When the number of the transmitting antennas is increased to 8, the PUSCH transmission can support uplink transmission of 8 layers at maximum, support the adoption of multi-codeword to layer mapping, and correspondingly, a plurality of codewords can be introduced to the PUSCH. Among them, an implementation of uplink communication using a multi-codeword to layer mapping method is being studied to improve transmission quality. However, the configuration of multiple codewords in uplink PUSCH transmission for multiple codewords is still under study.

Therefore, the present disclosure provides an uplink communication method, by configuring multiple codewords in PUSCH transmission, so as to solve the problem of configuration of multiple codewords introduced in supporting maximum 8-layer uplink PUSCH transmission, so that PUSCH transmission supports higher transmission rate and throughput rate.

The codeword used for uplink PUSCH transmission may be indicated based on a control information indication field in downlink control indication information (downlink controlinformation, DCI).

The control information indication field includes a modulation and coding scheme (Modulation and Coding Scheme, MCS) indication field, a redundancy version (Redundancy Version, RV) indication field, a new data (New Data Indicator, NDI) indication field, and the like.

In the uplink transmission method provided by the embodiment of the disclosure, the network device configures the maximum number of codewords supported by the terminal for uplink communication based on the PUSCH, and sends indication information to the terminal, so that the terminal determines the number of control information corresponding to the number of codewords actually contained in the DCI.

Fig. 3 is a flow chart illustrating an upstream communication method, as shown in fig. 3, performed by a terminal, according to an exemplary embodiment, including the following steps.

In step S11, indication information sent by the network device is received, where the indication information is used to instruct the terminal to determine the number of control information based on the configuration information.

In the embodiment of the disclosure, the configuration information is used for configuring the maximum number of codewords supported by the terminal for communication based on the PUSCH. The configuration information may be determined by the terminal according to a protocol convention or by the terminal receiving configuration information sent by the network device. The configuration information may be carried in radio resource control (Radio Resource Control, RRC) signaling, where the terminal is configured to perform the maximum number of codewords supported by uplink communication based on PUSCH through the RRC signaling.

In the embodiment of the present disclosure, the number of control information is used to determine the number of codewords actually contained in DCI, which is used to schedule PUSCH.

In the embodiment of the disclosure, the indication information is sent by the network device. The indication information may include DCI, or media access control element (Medium Access Control Control Element, MAC CE) information.

In the uplink communication method provided by the embodiment of the disclosure, the control information of the same codeword corresponds to a group of control information indication fields, and the control information of different codewords corresponds to different groups of control information indication fields.

Wherein the control information of the same codeword corresponds to a set of control information indicator fields.

The set of control information indication fields may include one or more of MCS indication fields, RV indication fields, and NDI indication fields. For example, the set of control information indication fields may include an MCS indication field, an RV indication field, and an NDI indication field. Or the set of control information indication fields may include a combination of MCS indication fields, RV indication fields, and NDI indication fields. For example, the set of control information indication fields may include MCS indication and RV indication fields, or MCS indication fields and NDI indication fields, or RV indication fields and NDI indication fields. Or the set of control information indication fields may include one of MCS indication fields, RV indication fields, and NDI indication fields. For example, the set of control information indication fields may include an MCS indication field, or include an RV indication field, or include an NDI indication field.

Wherein, the control information indication domains included in the different sets of control information indication domains are the same or different. For example, in an uplink communication method provided in the embodiments of the present disclosure, two codewords CW0 and CW1 are used for uplink PUSCH transmission. For example, a set of control information for configuring CW0 indicates that the field includes MCS, NDI and RV. A set of control information configuring CW1 indicates that only MCS and NDI may be configured in the domain and RV of CW0 is used.

In the uplink communication method provided by the embodiment of the present disclosure, PUSCH may include PUSCH of different types.

In the embodiment of the present disclosure, the PUSCH scene may include a PUSCH of a Configured Grant (CG), or the PUSCH may include a PUSCH of a scheduling grant (DG).

Wherein, CG PUSCH is denoted as unlicensed PUSCH, and uplink PUSCH grant is provided by RRC signaling configuration in CG PUSCH, including activation of grant. The terminal configures all transmission parameters through RRC signaling, including the maximum number of codewords supported by CG PUSCH. DG PUSCH is denoted dynamically granted PUSCH, in which all transmission parameters are configured by dynamic RRC signaling, including the maximum number of codewords supported by DG PUSCH. The terminal takes effect immediately upon correct reception of the RRC signaling configuration and starts transmitting with dynamically configured grants.

The RRC signaling configuration may include RRC signaling added in PUSCH configuration (PUSCH-Config) of the terminal, and the terminal configures the maximum number of codewords supported by DG PUSCH through parameter maxnrofcodewordsschedule bydci in the RRC signaling configuration. Alternatively, the configuration information may include RRC signaling added in higher layer signaling (configurable grant configuration) of the terminal, and the maximum number of codewords supported by the CG PUSCH is configured through a configuration parameter maxnrofcodewordsschedule bydci. Wherein, maxnrofcodewordsschedule bydci may represent the maximum number of codewords configured for different types of PUSCH scenarios.

In the embodiment of the present disclosure, the terminal may determine, by receiving the indication information sent by the network device, the number of control information actually including the number of codewords in the DCI for scheduling PUSCH in uplink communication, and further determine the number of codewords actually used.

In the uplink communication method provided by the embodiment of the present disclosure, two codewords are adopted for uplink PUSCH transmission, which may be respectively represented as a first codeword and a second codeword. The first codeword may be understood as codeword CW0 used in uplink PUSCH transmission with rank less than or equal to 4. The second codeword can be understood as a codeword CW1 that is newly added to support the maximum 8-layer uplink PUSCH transmission. The second codeword is configured in embodiments of the present disclosure.

In the embodiment of the disclosure, the terminal may determine configuration information corresponding to uplink communication. The configuration information is used for configuring the maximum number of codewords supported by the terminal for uplink communication based on the PUSCH.

In an example, the terminal determines, by determining the configuration information, the maximum number of codewords supported by the terminal for uplink communication based on PUSCH, and if the maximum number of codewords supported by the terminal is two, that is, the terminal supports two codewords for uplink PUSCH transmission, the maximum number of codewords may be represented as a first codeword CW0 and a second codeword CW1, respectively. A set of control information indication fields indicated in the second codeword CW1 in the DCI corresponding to the scheduled PUSCH is configured by the configuration information.

In an example, when the terminal determines that the maximum number of codewords supported by the terminal for uplink communication based on PUSCH in the configuration information is 1, that is, in RRC signaling configuration, the parameter maxnrofcodewordsschedule bydci is configured to be n1, the maximum number of codewords supported by PUSCH is indicated as one, and the codeword may be the first codeword CW0. If the terminal determines that the number of control information corresponding to the number of actually included codewords is two in the DCI for scheduling PUSCH by receiving the instruction information, the control information instruction field corresponding to the second codeword CW1 in the DCI for scheduling PUSCH, that is, the set of control instruction information fields indicated in the second codeword CW1 in the DCI in which the configuration information does not include the PUSCH is not enabled because the number of supported maximum codewords configured by the terminal is one at this time. At this time, only one set of control information indication fields indicated in the first codeword CW0 in the DCI capable of scheduling PUSCH can be enabled.

In an example, when the terminal determines that the maximum number of codewords supported by the terminal for uplink communication based on PUSCH in the configuration information is 2, that is, in RRC signaling configuration, the parameter maxnrofcodewordsschedule bydci is configured to be n2, the maximum number of codewords supported by PUSCH is two, and the two codewords may be the first codeword CW0 and the second codeword CW1 respectively. If the terminal determines that the number of control information corresponding to the number of actually included codewords in the DCI for scheduling PUSCH is two by receiving the indication information, the control information indication field corresponding to the second codeword CW1 in the DCI for scheduling PUSCH is enabled by the indication information, that is, the configuration information includes a set of control indication information fields indicated in the second codeword CW1 in the DCI for scheduling PUSCH. At this time, a set of control information indication fields indicated in the second codeword CW1 in DCI capable of scheduling PUSCH can be enabled.

In the embodiment of the present disclosure, when the terminal determines that the maximum number of codewords supported in the configuration information is two, a set of control information indication fields indicated in the second codeword CW1 in the DCI enabling the corresponding scheduling PUSCH is configured based on the configuration information.

In the embodiment of the disclosure, in PUSCH scenes of different types, the terminal receives different indication information to determine the number of control information corresponding to the number of codewords actually included in DCI for scheduling PUSCH.

In an example, when the PUSCH scene type is DG PUSCH and the maximum number of codewords supported by the terminal for uplink communication based on PUSCH is 1, that is, the RRC signaling configuration parameter maxnrofcodewordsschedule bydci is n1, it indicates that the maximum number of codewords supported by DG PUSCH is one, and the codeword may be the first codeword CW0. Further, when the terminal receives the indication information and determines that the number of the control information actually including the number of the code words is one, a group of control information indication fields corresponding to the first code word CW0 in the DCI of the scheduling DG PUSCH is enabled.

In an example, when the PUSCH scene type is DG PUSCH and the maximum number of codewords supported by the terminal for uplink communication based on PUSCH is 1, that is, the RRC signaling configuration parameter maxnrofcodewordsschedule bydci is n1, it indicates that the maximum number of codewords supported by DG PUSCH is one, and the codeword may be the first codeword CW0. If the terminal receives the indication information and determines that the number of control information actually including the number of codewords is two, the terminal configures the maximum number of codewords supported at this time, so that a group of control information indication fields corresponding to the second codeword CW1 in the DCI for scheduling DG PUSCH, that is, a group of control indication information fields indicating the second codeword CW1 in the DCI for scheduling DG PUSCH are not included in the configuration information. At this time, only one set of control information indication fields indicating the first codeword CW0 in DCI capable of scheduling DG PUSCH can be enabled.

In an example, when the PUSCH scene type is DG PUSCH and the maximum number of codewords supported by the terminal for uplink communication based on PUSCH is 2, that is, the RRC signaling configuration parameter maxnrofcodewordsschedule bydci is n2, it indicates that the maximum number of codewords supported by DG PUSCH is two, and the two codewords may be the first codeword CW0 and the second codeword CW1 respectively. If the terminal receives the indication information and determines that the number of the control information actually including the number of the codewords is two, enabling a group of control information indication fields corresponding to the second codeword CW1 in the DCI for scheduling DG PUSCH by the indication information, that is, a group of control information indication fields indicated in the second codeword CW1 in the DCI for scheduling DG PUSCH in the configuration information.

In an example, the PUSCH scene type may also be CG PUSCH.

In the embodiment of the disclosure, the terminal can determine the maximum number of codewords supported by the terminal in uplink communication in different types of PUSCH scenes by determining parameters included in the configuration information.

In the uplink communication method provided by the embodiment of the present disclosure, the maximum number of codewords configured by the configuration information may be one or more.

In an example, the terminal may add RRC signaling configuration to PUSCH-Config, add parameter maxnrofcodewordsschedule bydci to RRC signaling, and configure to 1, which indicates that the maximum number of codewords supported by DG PUSCH is one. Or, the terminal may add RRC signaling configuration in configurable grantconfig, add parameter maxnrofcodewordsschedule bydci in RRC signaling, and configure to 1, which indicates that the maximum number of codewords supported by CG PUSCH is one.

In an example, the terminal may add RRC signaling configuration to PUSCH-Config, add parameter maxnrofcodewordsschedule bydci to RRC signaling, and configure to 2, which indicates that the maximum number of codewords supported by DG PUSCH is two. Or, the terminal may add RRC signaling configuration in configurable grantconfig, add parameter maxnrofcodewordsschedule bydci in RRC signaling, and configure to 2, which indicates that the maximum number of codewords supported by CG PUSCH is two.

In the embodiment of the present disclosure, in PUSCH scenarios of different types, the terminal may determine the value of parameter maxnrofcodewordsschedule bydci included in the configuration information, and the terminal may perform the maximum number of codewords supported by uplink communication.

In the uplink communication method provided by the embodiment of the present disclosure, when the number of control information corresponding to the number of actually included codewords in DCI is a plurality of, the indication information includes first indication information.

In the embodiment of the disclosure, the first indication information includes a plurality of sets of different control information indication fields corresponding to a plurality of different codewords, that is, one codeword corresponds to one set of control information indication fields. The first indication information comprises a control information indication domain corresponding to the maximum code word number. I.e. the number of groups of control information indication fields in the first indication information corresponds to the configured maximum number of codewords.

Wherein, the first indication information may include DCI.

In an example, when the configured maximum number of codewords is two and the number of control information actually including the number of codewords is also two, the first indication information includes two different sets of control information indication fields. When the number of the configured maximum code words is two and the number of the control information actually containing the number of the code words is one, two groups of different control information indication fields are still included in the first indication information.

In an example, in the configuration information, the maximum codeword number of the RRC signaling configuration in PUSCH-Config or configurable grant Config is configured as one in advance. If the number of actually included codewords is determined to be two by the first indication information, only one set of control indication information fields corresponding to one codeword is still included in the first indication information.

In an example, in the configuration information, the maximum codeword number of RRC signaling configuration in PUSCH-Config or configurable grant Config is configured in advance as two. If the number of actually included codewords is determined to be one by the first indication information, two sets of different control indication information fields corresponding to two different codewords are still included in the first indication information.

In the embodiment of the disclosure, the terminal can determine the number of the control information in the first indication information based on the configuration information to determine different groups of control information indication fields corresponding to different codewords contained in the first indication information.

In the uplink communication method provided by the embodiment of the disclosure, the terminal can receive the second indication information sent by the network device, and determine the actual maximum code word number when the terminal performs uplink communication based on the PUSCH.

The second indication information is used for indicating the actual maximum code word number when the terminal performs uplink communication based on the PUSCH, namely the number of the control information in the second indication information is consistent with the actual maximum code word number.

Wherein the second indication information may include a MAC CE. For example, the terminal may determine that the number of actual maximum codewords is two when the terminal performs uplink communication based on PUSCH by receiving MAC CE.

In an example, in the configuration information, the maximum number of codewords in the RRC signaling configuration in PUSCH-Config or configurable grant Config is configured as one in advance. If the number of control information actually including the number of codewords is determined to be two by the second indication information, the maximum number of codewords is updated to be two based on the second indication information.

In an example, in the configuration information, the maximum codeword number of RRC signaling configuration in PUSCH-Config or configurable grant Config is configured in advance as two. If the number of control information actually including the number of codewords is determined to be one by the second indication information, the maximum number of codewords is updated to be one based on the second indication information.

In the embodiment of the disclosure, the terminal can dynamically configure the maximum number of codewords in the configuration information through the second indication information so as to realize dynamic switching between the single codeword and the double codeword.

When it is determined that the second indication information indicates that the actual maximum number of codewords is a plurality, a new control information indication field for indicating a new codeword is added based on the second indication information, and the indication information including the new control information indication field is referred to as third indication information.

Fig. 4 is a flow chart of a method of upstream communication, as shown in fig. 4, according to an exemplary embodiment, including the following steps.

In step S21, it is determined that the maximum number of codewords indicated by the second indication information is a plurality and/or that the configured maximum number of codewords is a plurality.

In step S22, it is determined that the indication information includes third indication information, where the third indication information includes a plurality of sets of different control information indication fields corresponding to a plurality of different codewords, and the different sets of control information indication fields in the plurality of sets of control information indication fields are used to indicate the different codewords actually used by the terminal for uplink communication based on PUSCH.

Wherein, the third indication information may include DCI.

In an example, the terminal indicates that the actual maximum number of codewords is multiple in response to receiving the second indication information, that is, indicates that the terminal performs uplink communication based on PUSCH is multiple in the actual maximum number of codewords, and/or determines that the maximum number of codewords configured by the configuration information is multiple. For example, the terminal receives the MAC CE to instruct the terminal to perform uplink communication based on the PUSCH by two maximum numbers of codewords, and/or the terminal determines that the parameter maxnrofcodewordsschedule bydci in the RRC signaling is configured to be 2 in the PUSCH-Config or configured grant Config.

In an example, in determining the configuration information, in response to receiving the second indication information indicating that the actual maximum number of codewords is a plurality of, the terminal may add a new control information indication field for a second different codeword to DCI 0_1 or DCI 0_2, respectively, to obtain third indication information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords. For example, when the number of actual maximum codewords is two in the second indication information received by the terminal, a new control information indication field for the second codeword may be added to DCI 0_1 or DCI 0_2, respectively.

In one example, the DCI includes DCI0_1 or DCI 0_2. When the number of the actual maximum code words in the second indication information received by the terminal is multiple and the configured maximum code word number is configured to be multiple, multiple groups of new control information indication fields for multiple different code words can be added in DCI0_1 or DCI 0_2 respectively, so as to obtain third indication information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords. For example, when the number of actual maximum codewords is two in the second indication information received by the terminal and the configured maximum number of codewords is two, a new control information indication field for the second codeword may be added in DCI0_1 or DCI 0_2, respectively.

In an example, in the receiving instruction information of the terminal, in response to receiving the second instruction information that the actual maximum number of codewords is plural, and when the configured maximum number of codewords is configured as one, a new control information instruction field for a second different codeword may be added to DCI0_1 or DCI 0_2, respectively, to obtain third instruction information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords. For example, when the number of actual maximum codewords is two in the second indication information received by the terminal and the configured maximum number of codewords is configured as one, a new control information indication field for the second codeword may be added in DCI0_1 or DCI 0_2, respectively.

In the embodiment of the present disclosure, when the second indication information indicates that the actual maximum number of codewords is multiple and/or the configured maximum number of codewords is multiple, the terminal enables a new set of control information indication fields indicated in the newly added codeword in the DCI for scheduling PUSCH through the third indication information.

In the uplink communication method provided by the embodiment of the present disclosure, when the number of codewords configured by the configuration information is a plurality of codewords, the indication information includes fourth indication information and fifth indication information.

In an embodiment of the present disclosure, the fourth indication information includes a plurality of sets of different control information indication fields for respectively indicating a plurality of different codewords. The fifth indication information is used for indicating a group of control information indication fields corresponding to the enabled code word among the groups of different control information indication fields included in the enabled fourth indication information.

For example, the fourth indication information may include two sets of control information indication fields for indicating two codewords. The fifth indication information is used for enabling one set of control information indication fields or two sets of control information indication fields in the fourth indication information.

The set of control information indication fields of the codeword in the fourth indication information is enabled in the embodiments of the present disclosure, which may be understood as a set of control information indication fields corresponding to the codeword in the fourth indication information. The set of control information indication fields of the codeword in the fourth indication information is not enabled in the embodiments of the present disclosure, and may be understood as a set of control information indication fields corresponding to the codeword in the fourth indication information is not used.

In an example, the maximum number of codewords supported by the terminal for uplink communication based on PUSCH is determined to be two, i.e., the RRC signaling configuration parameter maxnrofcodewordsschedule bydci is n2. At this time, the fourth indication information includes two sets of control information indication fields. I.e. two different sets of control information indication fields comprising two different code words in the fourth indication information, may comprise a set of control information indication fields of the first code word CW0 and a set of control information indication fields of the second code word CW1. Further, the terminal enables two different sets of control information indication fields of two different codewords in the fourth indication information through the fifth indication information sent by the network device, namely, a set of control information indication fields of a first codeword CW0 and a set of control information indication fields of a second codeword CW1 in the fourth indication information are used, and the number of actually used codewords is determined to be two, namely, the first codeword CW0 and the first codeword CW1.

For example, the enabled codeword may be a first codeword. When the number of the transmitting antennas is increased to 8, the PUSCH transmission can support uplink transmission of the maximum 8 layers, if the terminal responds that the fifth indication information is not received, the terminal is instructed to apply the first codeword CW0 to carry out uplink communication through the fourth indication information when the rank is less than or equal to 4, and the terminal is instructed to apply the second codeword CW1 to carry out uplink communication through the fourth indication information when the rank is less than or equal to 4 and less than or equal to 8. If the terminal responds to the receiving of the fifth indication information, enabling the control information indication field corresponding to the first codeword in the fourth indication information, wherein the number of codewords used by the terminal in uplink communication is one at the moment, namely, when 1 is less than or equal to rank is less than or equal to 8, the terminal is indicated to only apply the first codeword CW0 to carry out uplink communication through the fifth indication information.

For example, the enabled codeword may be a second codeword. When the number of the transmitting antennas is increased to 8, the PUSCH transmission can support uplink transmission of the maximum 8 layers, if the terminal responds that the fifth indication information is not received, the terminal is instructed to apply the first codeword CW0 to carry out uplink communication through the fourth indication information when the rank is less than or equal to 4, and the terminal is instructed to apply the second codeword CW1 to carry out uplink communication through the fourth indication information when the rank is less than or equal to 4 and less than or equal to 8. If the terminal responds to the receiving of the fifth indication information, enabling the control information indication field corresponding to the second codeword in the fourth indication information, wherein the number of codewords used by the terminal in uplink communication is one at the moment, namely, when 1 is less than or equal to rank is less than or equal to 8, the terminal is indicated to only apply the second codeword CW1 to carry out uplink communication through the fifth indication information.

In the uplink communication method provided by the embodiment of the disclosure, the fourth indication information includes DCI, the fifth indication information includes DCI, and the fourth indication information and the fifth indication information correspond to different code points of the same newly defined control information indication domain.

In the embodiment of the disclosure, the code point may include an indication field added to 1bit, or the code point may include a special code point.

In some embodiments, the 1bit indication field is added to be used for indicating that the corresponding codeword is enabled when the terminal performs PUSCH transmission. For example, the indication field added with 1bit is 0, and may be used to indicate that the codeword used by the terminal for PUSCH transmission is the first codeword CW0. The indication field added with 1bit is 1, and can be used for indicating the codeword used by the terminal for PUSCH transmission to be the second codeword CW1. For another example, the code word used to instruct the terminal to perform PUSCH transmission may be the first code word CW0, using a special code point of 0. The special code point is 1, and the code word used for instructing the terminal to perform PUSCH transmission is the first code word CW1.

In the embodiment of the disclosure, the terminal determines, through the code point, a codeword for instructing the terminal to perform PUSCH transmission.

In an uplink communication method provided by an embodiment of the present disclosure, each set of control information indication fields in a plurality of sets of control information indication fields includes at least one of the following control information indication fields: MCS indication field, RV indication field and new data NDI indication field.

In the disclosed embodiment, the DCI includes DCI 0_1 or DCI 0_2. When the maximum number of codewords supported by the terminal for performing layer mapping in uplink communication is configured into a plurality of configuration information, multiple groups of new control information indication fields for a plurality of different codewords can be respectively added in DCI 0_1 or DCI 0_2.

In the embodiment of the present disclosure, each control information indication field included in any one set of control information indication fields may be defined separately, that is, each control information indication field is defined separately to indicate a corresponding codeword. Alternatively, each control information indication field included in any one set of control information indication fields may be defined jointly, i.e. each control information indication field is defined to jointly indicate a corresponding one of the codewords.

In the uplink communication method provided by the embodiment of the present disclosure, a terminal solves a series of standardized problems caused by introducing multiple codewords in uplink PUSCH transmission by configuring the multiple codewords in uplink PUSCH transmission, so as to implement switching between a single codeword and multiple codewords, so that uplink PUSCH transmission supports higher transmission rate and throughput rate.

Fig. 5 is a flow chart illustrating another upstream communication method, as shown in fig. 5, performed by a network device, according to an exemplary embodiment, including the following steps.

In step S31, instruction information for instructing the terminal to determine the number of control information based on the configuration information is transmitted to the terminal.

In the embodiment of the disclosure, the configuration information is used for configuring the maximum number of codewords supported by the terminal for communication based on the PUSCH. The configuration information may be determined by the terminal according to a protocol convention or by configuration information sent by the network device to the terminal. The configuration information may be carried in radio resource control (Radio Resource Control, RRC) signaling, where the terminal is configured to perform the maximum number of codewords supported by uplink communication based on PUSCH through the RRC signaling.

In an example, the PUSCH scene type may also be CG PUSCH.

Wherein, the first indication information may include DCI.

In an example, when the maximum number of codewords configured by the terminal is two and the number of control information actually including the number of codewords is also two, the second indication information includes two different sets of control information indication fields. When the maximum number of codewords configured by the terminal is two and the number of control information corresponding to the number of codewords actually contained in the DCI for scheduling PUSCH is one, only one set of control information indication fields is included in the second indication information.

In an example, in the configuration information, the maximum number of codewords in the RRC signaling configuration in PUSCH-Config or configurable grant Config is configured as one in advance. And if the number of the control information actually containing the number of the code words is determined to be two through the second indication information, updating the RRC signaling configuration and the control information indication domain configuration in the configuration information based on the second indication information. I.e. increasing the maximum number of codewords in the RRC signaling configuration and increasing the new control information indication field for the second codeword.

In an example, in the configuration information, the maximum codeword number of RRC signaling configuration in PUSCH-Config or configurable grant Config is configured in advance as two. If the number of the control information actually including the number of the code words is determined to be one through the second indication information, in order to reduce signaling overhead, the RRC signaling configuration and the control information indication domain configuration in the configuration information are updated based on the second indication information. I.e. reducing the maximum number of codewords configured in the RRC signaling configuration and reducing the control information indication field for the second codeword.

Fig. 6 is a flow chart of a method of upstream communication, as shown in fig. 6, according to an exemplary embodiment, including the following steps.

In step S41, it is determined that the maximum number of codewords indicated by the second indication information is a plurality and/or that the configured maximum number of codewords is a plurality. In step S42, it is determined that the indication information includes third indication information, where the third indication information includes a plurality of sets of different control information indication fields corresponding to a plurality of different codewords, and the different sets of control information indication fields in the plurality of sets of control information indication fields are used to indicate the different codewords actually used by the terminal for uplink communication based on PUSCH.

Wherein, the third indication information may include DCI.

In the disclosed embodiment, the DCI includes DCI 0_1 or DCI 0_2. When the second indication information received by the terminal indicates that the number of maximum codewords actually used by the terminal for uplink communication based on the PUSCH is multiple, or the number of maximum codewords supported by the terminal for uplink communication is multiple in the configuration information, multiple groups of new control information indication fields for multiple different codewords can be added in the DCI 0_1 or the DCI 0_2 respectively. For example, when the second indication information received by the terminal indicates that the maximum number of codewords actually used for uplink communication by the terminal based on PUSCH is two, a new control information indication field for the second codeword may be added to DCI 0_1 or DCI 0_2, respectively. Alternatively, when the maximum number of codewords supported by the terminal for uplink communication is configured as two in the configuration information, a new control information indication field for the second codeword may be added to DCI 0_1 or DCI 0_2, respectively.

In an example, in receiving the indication information by the terminal, in response to receiving the second indication information to indicate that the actual maximum number of codewords is two, a new control information indication field for a second different codeword may be added to DCI 0_1 or DCI 0_2, respectively, to obtain third indication information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords.

In an example, in determining the configuration information by the terminal, in response to the maximum number of codewords configured being two, a new control information indication field for a second different codeword may be added to DCI 0_1 or DCI 0_2, respectively, to obtain third indication information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords.

In an example, in the terminal receiving the indication information, in response to receiving the maximum number of codewords indicated in the second indication information, and in the terminal determining the configuration information, in response to the configuration information, the maximum number of codewords configured is also two, new control information indication fields for the second different codewords may be added in DCI 0_1 or DCI 0_2, respectively, to obtain third indication information. The third indication information includes two sets of different control information indication fields corresponding to two different codewords.

In an embodiment of the disclosure, the fourth indication information includes a plurality of sets of different control information indication fields for respectively indicating a plurality of different codewords. The fifth indication information is used for indicating a group of control information indication fields corresponding to the enabled code word among the groups of different control information indication fields included in the enabled fourth indication information.

For example, the fourth indication information may include two sets of control information indication fields.

In an example, the maximum number of codewords supported by the terminal for uplink communication based on PUSCH is determined to be two, i.e., the RRC signaling configuration parameter maxnrofcodewordsschedule bydci is n2. The fourth indication information indicates the terminal to determine the number of the control information based on the configuration information so as to determine different groups of control information indication fields corresponding to different codewords contained in the fourth indication information. At this time, the fourth indication information includes two sets of control information indication fields. I.e. the fourth indication information comprises two different sets of control information indication fields for two different code words, a set of control information indication fields for the first code word CW0 and a set of control information indication fields for the second code word CW 1. Further, the terminal determines the number of codewords used when the terminal performs uplink communication according to the fifth indication information sent by the network device and in response to receiving the control information indication field corresponding to the enabled codeword in the fourth indication information.
