Embodiments of the present invention are described below with reference to the drawings. The PUSCH transmission method, the PUSCH transmission control method and the related equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.
Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal (UE) 11 and a network device 12, where the terminal 11 may be a User terminal or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited. The network device 12 may be a 5G base station, a later version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.
Referring to fig. 2, fig. 2 is a flowchart of a method for transmitting a PUSCH on a physical uplink shared channel according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
step 201, receiving M pieces of downlink control information DCI, where the M pieces of DCI are used to schedule M PUSCHs;
step 202, transmitting the M PUSCHs;
wherein the M DCIs belong to K control resource sets, the K control resource sets are associated with N control resource set group identifiers, M is an integer greater than 1, K is a positive integer less than or equal to N, and N is a positive integer; the M DCIs satisfy: hybrid automatic repeat request (HARQ) process identifiers are the same; and the New Data Indicator (NDI) is the same.
In the embodiment of the present invention, a network device sends M pieces of DCI to a terminal, and the network device may include one or more TRPs. The M DCIs may be from the same TRP or from different TRPs, that is, one or more TRPs transmit M DCIs to a terminal to schedule transmission of M PUSCHs. Wherein, one TRP may transmit one or more DCIs to a terminal to schedule the terminal to transmit one or more PUSCHs.
Take M equal to 2 as an example for explanation. The two received DCIs may belong to the same Control resource set (CORESET) or may belong to different Control resource sets; when two DCIs belong to different control resource sets, the two control resource sets may be associated with the same control resource set group identity (e.g., the higher layer parameter coresetpoieldindex) or may be associated with different control resource set group identities. Optionally, one control resource set group identity corresponds to one TRP. That is, one or more control resource sets of each TRP are associated with the same control resource set group identity and control resource sets of different TRPs are associated with different control resource set group identities.
Optionally, redundancy Versions (RVs) of Transport Blocks (TBs) carried in the PUSCH transmitted by the terminal to one or more TRPs may be the same or different.
In the embodiment of the invention, when N is equal to 1, the same TRP can send M DCIs in a period of time to schedule the terminal to send M PUSCHs without judging whether each PUSCH transmission is correct or not and then to schedule retransmission, so that the situation that the terminal does not detect a certain DCI or PUSCH transmission error and needs to perform DCI scheduling PUSCH retransmission again due to poor channel quality (such as short-time shielding or deep channel fading) in time can be avoided, and the reliability of DCI transmission and PUSCH transmission is improved.
When N is larger than 1, the terminal receives M DCIs sent by a plurality of TRPs, and sends M PUSCHs to the TRPs based on the M DCIs, so that when the terminal is shielded from one of the TRPs, DCIs of other TRPs can be received or PUSCHs can be sent to other TRPs, thereby further effectively improving the reliability of DCI transmission and PUSCH transmission and ensuring the requirement of URLLC service transmission.
For example, each TRP sends a Physical Downlink Control Channel (PDCCH) in its respective control resource set (each control resource set is associated with a different identifier to distinguish the TRP, e.g., a control resource set group identifier), and the PUSCH may schedule one or more PUSCH transmissions including the same Transport Block (TB) according to configuration or indication, where each PUSCH transmission is a different RV version of a TB when multiple PUSCH transmissions are included. And one PUSCH scheduled by each TRP is transmitted by using the power control parameter and the beam space relation corresponding to the TRP according to the configuration or the indication.
The embodiment of the invention receives M pieces of downlink control information DCI, wherein the M pieces of DCI are used for scheduling M PUSCHs; transmitting the M PUSCHs; wherein the M DCIs belong to K control resource sets, the K control resource sets are associated with N control resource set group identifiers, M is an integer greater than 1, K is a positive integer less than or equal to N, and N is a positive integer; the M DCIs satisfy: the HARQ process identifications of the hybrid automatic repeat request are the same; and the new data indication NDI is the same. The terminal can transmit the PUSCH after receiving any one of the M DCIs, so that the reliability of receiving the DCI can be ensured, and the reliability of transmitting the PUSCH is improved. Meanwhile, at least two PUSCHs can be transmitted, so that the reliability of receiving the PUSCHs by the network equipment is improved. Therefore, the embodiment of the invention improves the reliability of PUSCH transmission and reduces the transmission delay of the PUSCH.
Optionally, a time interval between the receiving time of the first DCI and the receiving time of the second DCI is smaller than a first preset value;
and/or the time interval between the receiving time of the first DCI and the receiving time of the second DCI is greater than a second preset value, and the first preset value is greater than the second preset value;
the first DCI and the second DCI are DCIs received twice in the M DCIs, or the first DCI is a DCI received earliest in the M DCIs, and the second DCI is a DCI received latest in the M DCIs.
In this embodiment of the present invention, the M pieces of DCI may be understood as DCI in which a PUSCH received in a period of time and an indication has the same HARQ process identity (HARQ process ID) and the same NDI (that is, is not inverted), where a first DCI is a DCI received earliest in the M pieces of DCI, a second DCI is a DCI received latest in the M pieces of DCI, and a start symbol or an end symbol of a PDCCH where the first DCI is located and a start symbol or an end symbol of a PDCCH where the second DCI is located are separated by a distance smaller than (or less than or equal to) a first preset value (for example, T symbols); another understanding is that: after receiving and detecting the first DCI, the terminal determines a starting symbol or an ending symbol of a PDCCH where the first DCI is located, and can receive DCI which has the same HARQ process identification and the same NDI as the first DCI in the following T symbols; and after the last T symbols, the terminal does not expect to receive the DCI which has the same HARQ process identification and the same NDI as the first DCI, or the terminal does not process the received DCI which has the same HARQ process identification and the same NDI as the first DCI after the last T symbols.
The time interval between the receiving time of the first DCI and the receiving time of the second DCI is smaller than the first preset value, so that the transmitted TB occupies the cache for a long time, therefore, the embodiment of the invention improves the utilization rate of the cache and reduces the complexity of the terminal.
Optionally, the M DCI may satisfy at least one of:
the indicated time frequency resources are the same or different in size;
the indicated Modulation and Coding Scheme (MCS) is the same or different.
In this embodiment, the time-frequency resource sizes indicated by any two pieces of DCI are the same or different, and the modulation and coding schemes MCS indicated by any two pieces of DCI are the same or different. For example, in an embodiment, the time-frequency resource sizes indicated by the M pieces of DCI are the same, and indicate that the modulation and coding schemes MCS are the same.
In an embodiment, the M PUSCHs include a first PUSCH and a second PUSCH, the DCI scheduled for the first PUSCH is attributed to a first set of control resources, and the DCI scheduled for the second PUSCH is attributed to a second set of control resources, where the control resource set group identification associated with the first set of control resources is different from the control resource set group identification associated with the second set of control resources. In other words, in the present embodiment, the first PUSCH and the second PUSCH are transmitted to different TRPs.
Optionally, the start symbol of the first PUSCH precedes the end symbol of the second PUSCH and follows the start symbol of the second PUSCH.
The transmission of one PUSCH may be understood as one PUSCH transmission or multiple PUSCH repeated transmissions, and is not limited herein. As shown in fig. 3, the first PUSCH transmission may include L1 PUSCH transmissions, and the second PUSCH transmission may include L2 PUSCH transmissions. Wherein, the L1 times PUSCH transmission may be continuous, or may have a certain time interval between two adjacent transmissions; the same L2 PUSCH transmissions may be consecutive or may have a certain time interval between two adjacent transmissions. The starting symbol of the first PUSCH may be understood as a starting symbol of a first PUSCH transmission in L1 PUSCH transmissions, the starting symbol of the second PUSCH may be understood as a starting symbol of a first PUSCH transmission in L2 PUSCH transmissions, and the ending symbol of the second PUSCH may be understood as an ending symbol of a last PUSCH transmission in L2 PUSCH transmissions.
In other words, in the embodiment of the present invention, the terminal may schedule another PUSCH of the same HARQ process and NDI by a DCI (format 0_0 or 0_1) scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) or a Modulation and coding scheme Cell Radio Network Temporary Identifier (MCS-C-RNTI) before one PUSCH transmission is ended.
Further, the power control parameter of the PUSCH is determined by a target power control parameter, where the target power control parameter is a power control parameter corresponding to a control resource set group identifier associated with a control resource set to which the target DCI belongs; the target DCI is DCI for scheduling the PUSCH.
The power control parameters comprise open-loop power control parameters and closed-loop power control parameters. It should be appreciated that each control resource set group identification corresponds to the open-loop power control parameter configured by higher layer parameters. In this embodiment, the open-loop power control parameter is a target open-loop power control parameter, and a control resource set group id corresponding to the target open-loop power control parameter is the same as a control resource set group id associated with the DCI home control resource set.
Optionally, in an embodiment, the DCI carries the closed-loop power control parameter, where the closed-loop power control parameter is used to control the transmission power of the PUSCH scheduled by the DCI.
Further, the DCI carries indication information, where the indication information is used to control sending of a PUSCH scheduled by the DCI, and the indication information includes a Sounding Reference Signal Resource Indicator (SRI) and/or a Transmit Precoding Matrix Indicator (TPMI).
The SRI is used for indicating SRS resources of a target SRS resource group, and a control resource set group identifier corresponding to the target SRS resource group is the same as a control resource set group identifier associated with the DCI attributive control resource set.
In this embodiment, the closed-loop power control parameter and the indication information carried in the DCI are used to adjust the sending of the PUSCH scheduled by the DCI.
Optionally, in an embodiment, before the sending the M PUSCHs, the method further includes:
determining a spatial relationship (spatial relationship) of the PUSCH transmission.
In the embodiment of the present invention, the spatial relationship of PUSCH transmission scheduled by each DCI may be determined by the DCI, and specifically, the spatial relationship of PUSCH transmission is determined according to the SRI when the SRI carried in the DCI for PUSCH is scheduled; and under the condition that the SRI not carried in the DCI of the scheduling PUSCH is carried, determining the default spatial relationship as the spatial relationship of the PUSCH transmission.
Optionally, the determination of the default spatial relationship may be set according to actual needs, for example, in an embodiment, the default spatial relationship corresponds to a spatial relationship of a target Physical Uplink Control Channel (PUCCH) resource. In another embodiment, the default spatial relationship corresponds to a Transmission Configuration Indicator (TCI) state or Quasi co-location (QCL) of the smallest indexed control resource set of the target control resource set group identification. The target PUCCH resource is a PUCCH resource with a minimum index in PUCCH resources corresponding to a target control resource set identifier, and the target control resource set identifier is a control resource set identifier associated with a control resource set to which the DCI belongs.
In this embodiment, under the condition that the SRI not carried in the DCI for scheduling the PUSCH is performed, which default spatial relationship the terminal adopts as the spatial relationship for PUSCH transmission may be determined according to a currently satisfied condition.
For example, the default spatial relationship corresponds to a spatial relationship of a target physical uplink control channel PUCCH resource when a first preset condition is satisfied;
the default spatial relationship corresponds to a transmission configuration indication TCI status or quasi co-located QCL of a control resource set of a smallest index in the target control resource set group identity, if a second preset condition is met.
Optionally, the first preset condition includes:
not configuring preset high-level parameters, or not enabling the preset high-level parameters;
activating a PUCCH resource corresponding to the target control resource set identification on an uplink Bandwidth Part (BWP) for the terminal;
and in the PUCCH resources corresponding to the target control resource set identification, a spatial relationship is configured on part or all of the PUCCH resources.
The preset higher layer parameter may be denoted as "enabledeaultbeampforpusch 0_0". The scheme for meeting the first preset condition can be understood as follows: the high-level parameter "enabledefailbetapplforpusch 0_0" or "enabledefailbetapbedforpusch 0_0" is not enabled, and a PUCCH resource (PUCCH resource associated to the target control resource set group identifier) is configured for the UE on the active uplink BWP, and the PUCCH resource is configured with a spatial relationship, then the spatial relationship of the DCI scheduled PUSCH transmission corresponds to the spatial relationship of the PUCCH resource of the minimum index associated to the target control resource set group identifier.
The second preset condition includes:
the preset high level parameter is enabled;
activating PUCCH resources corresponding to the target control resource set identification which are not configured for the terminal on the uplink BWP; or activating the uplink BWP to configure the PUCCH resource corresponding to the target control resource set identifier for the terminal, where the PUCCH resource corresponding to the target control resource set identifier is not configured with a spatial relationship.
Wherein, when the second preset condition includes that a PUCCH resource corresponding to the target control resource set identifier is not configured for the terminal on the uplink BWP, a Path Loss Reference Signal (PL RS) of the power control parameter of the PUSCH is: and the RS corresponding to the TCI state of the control resource set with the smallest index in the target control resource set group identifier or the RS corresponding to the QCL Type D of the QCL (i.e., QCL Type-D RS).
In this embodiment of the present invention, when the second preset condition includes that the PUCCH resource corresponding to the target control resource set identifier is not configured for the terminal on the uplink BWP, a scheme meeting the second preset condition may be understood as: when the uplink BWP is not configured with PUCCH resources (associated with the PUCCH resource corresponding to the target control resource set identifier) and the UE is in the RRC connected state, the spatial relationship for PUSCH transmission refers to an RS of QCL Type-D corresponding to the QCL hypothesis of the control resource set associated with the smallest control resource set index of the target control resource set identifier (i.e., the default spatial relationship corresponds to the TCI state or QCL of the control resource set associated with the smallest control resource set index of the target control resource set identifier of the active downlink BWP of the cell where the PDCCH scheduling the PUSCH is located). The default PL RS (for power control) is the RS corresponding to the TCI state of the control resource set of the smallest control resource set index identified by the target control resource set group or the QCL Type-D RS of QCL.
When the second preset condition includes that the PUCCH resource corresponding to the target control resource set identifier is configured for the terminal on the uplink BWP, and the PUCCH resource corresponding to the target control resource set identifier is not configured with the spatial relationship, a scheme meeting the second preset condition may be understood as: the high-level parameter "enabledeaultbeam for PUSCH0_0" is enabled, and PUCCH resources are configured for the UE on the uplink BWP, but all PUCCH resources are not configured with spatial relationship and the terminal is in RRC connected state, and the spatial relationship and/or PL RS for PUSCH transmission refer to an RS that is an RS of QCL Type-D corresponding to the QCL hypothesis of the control resource set indexed by the smallest control resource set in the control resource set identified by the target control resource set group.
In other words, the spatial relationship of the PUSCH transmission refers to the default spatial relationship and/or PL RS of the PUCCH associated to the target control resource set group identity, i.e. the spatial setting (spatial relationship) of the PUCCH corresponds to the spatial setting (TCI state or QCL) received by the PDCCH transmitted in the control resource set that activates the smallest control resource set index associated to the target control resource set group identity in the downlink BWP on the primary serving cell (PCell).
Specific implementations of the present invention are described in detail below for a better understanding of the invention.
Each TRP sends a Physical Downlink Control Channel (PDCCH) in its respective control resource set (each control resource set is associated with a different identifier to distinguish the TRP, e.g., a control resource set group identifier), which may schedule a PUSCH that may include one or more PUSCH transmissions of a same Transport Block (TB) according to a configuration or indication, each PUSCH transmission being a different RV version of a TB when including multiple PUSCH transmissions. And one PUSCH scheduled by each TRP is transmitted by using the power control parameter and the beam space relation corresponding to the TRP according to the configuration or the indication.
The specific scheme is as follows:
the UE receives at least two DCIs.
Optionally, the two DCIs belong to different control resource sets, and the control resource sets correspond to different control resource set group identifiers (indexes (TRP IDs) for distinguishing TRPs, such as a higher layer parameter coresetpoilndex).
Optionally, the PUSCH scheduled by the at least two DCIs has the same HARQ process identifier, and the NDI is the same (i.e. not flipped).
Optionally, the time interval of the at least two DCIs satisfies a certain threshold, for example, is less than a predefined time (e.g., within one slot), is greater than a predefined time, and the like.
Optionally, the time-frequency resource sizes (RE numbers) indicated by the at least two DCIs are the same, and the MCSs are the same.
Optionally, the UE may schedule PUSCH for another same HARQ process and NDI by DCI scrambled by C-RNTI or MSC-C-RNTI (format 0_0 or 0_1) before one PUSCH transmission ends.
Optionally, the power control of one PUSCH transmission is determined by a power control parameter corresponding to a TRP ID (e.g., control resource set group identity) associated with a control resource set to which DCI scheduling the PUSCH belongs.
The upper layer parameters include open-loop power control parameters (e.g., a higher layer parameter PUSCH-PowerControl) corresponding to two coresetpoilndex. Closed loop power control indication, SRI and TPMI in the DCI only adjust PUSCH scheduled by DCI which belongs to the same TRP ID and is transmitted in the control resource set.
Optionally, default spatial relationship information (spatial relationship) for one PUSCH transmission is determined. For example, when there is no SRI indication in DCI format 0_0 (DCI format 0_0) scheduling, or when SRS is not configured for a higher layer parameter, in a multiple TRP scenario, when multiple DCIs schedule transmits multiple PUSCHs on active BWP, if SRI carried in DCI of PUSCH is scheduled, the spatial relationship of PUSCH transmission is determined by the SRI indication in DCI; if the SRI not carried in the DCI scheduling the PUSCH (e.g. DCI format 0_0), the spatial relationship of PUSCH transmission should satisfy:
1. the higher layer parameter "enabledeaultbeamplforpusch 0_0" or "enabledeaultbeampberpusch 0_0" is not enabled, and a PUCCH resource (PUCCH resource associated to the target control resource set group identifier) is configured for the UE on the active uplink BWP, and the PUCCH resource is configured with a spatial relationship, then the spatial relationship of the PUSCH transmission scheduled by the DCI corresponds to the spatial relationship of the PUCCH resource associated to the minimum index of the target control resource set group identifier.
2. The higher layer parameter "enabledeaultbeam for PUSCH0_0" is enabled, and when no PUCCH resource is configured for the UE on the uplink BWP (PUCCH resource associated with the target control resource set identifier) and the UE is in the RRC connected state, the spatial relationship for PUSCH transmission refers to an RS of QCL Type-D corresponding to the QCL hypothesis of the control resource set associated with the smallest control resource set index of the target control resource set identifier (i.e., the default spatial relationship corresponds to the TCI state or QCL of the control resource set associated with the smallest control resource set index of the target control resource set identifier of the active downlink BWP of the cell in which the PDCCH scheduling the PUSCH is located). The default PL RS (for power control) is the RS corresponding to the TCI state of the control resource set indexed by the smallest control resource set identified by the target control resource set group or the QCL Type-D RS of QCL.
3. The high-level parameter "enabledeaultbeam for PUSCH0_0" is enabled, and PUCCH resources are configured for the UE on the uplink BWP, but all PUCCH resources are not configured with spatial relationship and the terminal is in RRC connected state, and the spatial relationship and/or PL RS for PUSCH transmission refer to an RS that is an RS of QCL Type-D corresponding to the QCL hypothesis of the control resource set indexed by the smallest control resource set in the control resource set identified by the target control resource set group.
In other words, the spatial relationship of the PUSCH transmission refers to the default spatial relationship and/or PL RS of the PUCCH associated to the target control resource set group identity, i.e. the spatial setting of the PUCCH corresponds to the spatial setting (TCI state or QCL) of PDCCH reception sent in the control resource set of the smallest control resource set index associated to the target control resource set group identity in PCell uplink activated downlink BWP.
