detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure more clear, detailed description will be given below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a transmission method provided by an embodiment of the present disclosure. As shown in Figure 1, a transmission method, applied to a terminal, includes the following steps:

Step 101: Send N PUCCHs for repeated transmission; the N is an integer greater than or equal to 2.

In this embodiment, the terminal may send multiple PUCCHs that are repeatedly transmitted to multiple TRPs (Transmission Reception Points, transmission reception points) that are jointly transmitted. The N PUCCHs that are repeatedly transmitted can be understood as the N PUCCHs carrying the same UCI (Uplink Control Information, uplink control information). Among them, according to different formats, UCI information can include HARQ-ACK (Hybrid automatic repeat request acknowledgement, hybrid automatic repeat request acknowledgement), CSI (Channel State Information, channel state information), SR (Scheduling Request, scheduling request) and other information .

As shown in Figure 2, the terminal establishes a connection with the two TRPs that are jointly transmitted. The terminal can receive downlink control information from TRP11 and TRP12 respectively, and the terminal can also send PUCCH to the two TRPs at the same time based on the received downlink control information. The UCIs carried in the two PUCCHs are the same, and the two TRPs can receive the PUCCHs sent by the terminal. The two TRPs in the figure are just examples, and in practical applications, the number of TRPs may be greater than two.

By repeatedly transmitting the PUCCH to a plurality of TRPs that are jointly transmitted, the reliability of the repeated transmission can be improved.

From the perspective of a network-side device, the methods of the embodiments of the present disclosure include:

Partial PUCCHs of the N PUCCHs that are repeatedly transmitted are received; the N is an integer greater than or equal to 2.

In practical applications, the channel environment and spatial relationship parameters of multiple TRPs for repeated transmission are often different. In this case, if the terminal uses the same configuration for the repeated transmission of PUCCHs sent to different TRPs, it is impossible to achieve better transmission effect. In order to further improve the reliability of PUCCH repeated transmission, the embodiments of the present disclosure propose the following manners.

The first way is to improve the reliability of transmission based on the DCI (Downlink Control Information, downlink control information) of the scheduling PUCCH, which is described as follows.

Before transmitting the N PUCCHs of repeated transmissions, also include:

Receive M DCIs, each DCI includes first configuration information corresponding to a part of the PUCCHs in the N PUCCHs, and the CORESET pool indices configured by the CORESETs (Control resource set, control resource set) that carry the M DCIs are different , the M is an integer greater than or equal to 2.

For a network side device, such as a TRP, before receiving the N physical uplink control channels PUCCH repeatedly transmitted, the method according to the embodiment of the present disclosure further includes:

Before receiving part of the PUCCHs in the N physical uplink control channels PUCCHs that are repeatedly transmitted, the method further includes:

Sending a DCI, where the DCI includes first configuration information corresponding to a part of the PUCCHs in the N PUCCHs, the CORESET pool indices configured by the CORESETs carrying the M DCIs are different, and each DCI in the M DCIs corresponds to For the partial PUCCHs in the N PUCCHs, the M is an integer greater than or equal to 2.

That is, in the specific embodiment of the present disclosure, PUCCHs corresponding to different TRPs may be scheduled by different DCIs, and PUCCHs corresponding to the same TRP may be scheduled by the same DCI. The M DCIs may be sent by one of the TRPs, or may be sent by one of the TRPs or multiple TRPs that are jointly transmitted.

In this embodiment, the TRP corresponding to the DCI can be determined through the CORESET pool index configured by the CORESET of the DCI. For example, TRP0 is associated with coresetPoolIndex-r16=0, and TRP1 is associated with coresetPoolIndex-r16=1. Based on the above-mentioned associated resource pool index information, the TRP corresponding to the DCI can be determined. Each DCI can schedule at least one PUCCH in time sequence, and the TRP corresponding to the PUCCH, that is, the sender of the DCI, can be determined according to the above method.

Since the CORESET pool index configured by the CORESET of each DCI is different, the correspondingly configured TRP determined by the CORESET pool index is also different, and each DCI is used to indicate the first configuration information of the PUCCH sent to the corresponding TRP.

Take the terminal shown in FIG. 2 and the two TRPs jointly transmitting for information transmission as an example. The terminal receives two DCIs sent from TRP11 and TRP12, wherein the CORESET pool indices configured by the CORESETs of the two DCIs are different, and according to the CORESET pool indices, it can be determined that the two DCIs correspond to TRP11 and TRP12 respectively. When performing information transmission, the terminal can obtain the TRP11 corresponding to the DCI, and use the DCI to schedule the PUCCH sent to the TRP11; obtain the TRP12 corresponding to the DCI, and use the DCI to schedule the PUCCH of the sent TRP12.

Since PUCCHs on different TRPs are scheduled by different DCIs, transmission resources corresponding to the TRPs can be configured for the DCIs according to the conditions of the TRPs, such as the network environment. For example, the resources of the PUCCH of the TRP with better channel quality may be relatively less allocated, while the resources of the PUCCH of the TRP with the poor channel quality may be relatively more allocated. In this way, the PUCCH on the TRP can be scheduled more reasonably, the flexibility of the scheduling can be improved, and the reliability of the PUCCH transmission can be further improved.

Optionally, the first configuration information includes time-domain configuration information, where the time-domain configuration information is used to configure the N PUCCHs in the following two ways:

The first is continuous transmission of PUCCH corresponding to the same index parameter in the time domain.

This method can also be called sequential mapping. In this mapping method, the PDSCH-to-HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) _feedback timing indicator (PDSCH to HARQ timer) in the DCI determines the The time domain position of the first PUCCH transmission in the PUCCH scheduled by the DCI and the number of times the PUCCH is repeatedly transmitted. When allocated in the time domain, if the index parameters corresponding to multiple PUCCHs are the same, it can be determined that the corresponding TRPs are the same according to the index parameters, and the multiple PUCCHs corresponding to the same TRP can be continuously transmitted in the time domain.

The index parameter is a CORESET pool index configured by the CORESET where the DCI of the PUCCH is scheduled.

The second is that the index parameters corresponding to adjacent PUCCHs in the time domain are different.

This method can also be called cyclic mapping, that is to say, according to the PDSCH-to-HARQ_feedback timing indicator in the DCI, the time slot of the first PUCCH transmission is determined, and the PUCCH transmission is performed every other time slot, and according to the time slot repeated transmissions. When allocating in the time domain, if the index parameters corresponding to the multiple PUCCHs are different, the TRPs determined according to the index parameters are also different, and the multiple PUCCHs corresponding to different TRPs may be distributed in the time domain according to the time slot interval.

From the perspective of the network side device, the first configuration information includes time domain configuration information, and the M DCIs are used to configure the N PUCCHs in the following two ways:

The first is continuous transmission of PUCCH corresponding to the same index parameter in the time domain;

The second is that the index parameters corresponding to adjacent PUCCHs in the time domain are different;

The index parameter is the CORESET pool index configured by the control resource set CORESET where the DCI of the PUCCH is scheduled.

In this embodiment, the PDSCH (Physical downlink shared channel, physical downlink shared channel) scheduled by DCI is counted, and the time domain position of PUCCH transmission can be determined. Resource Control, radio resource control) configuration. As shown in FIG. 3 , in the process that the terminal performs four repeated transmissions, the parameters of the PUCCH for each repeated transmission are the same, and the RRC configures the number of times the PUCCH repeats the time slot.

In order to further understand the above two configuration manners, an example is given below.

For example, as shown in FIG. 4 , the base station sends downlink control information to the terminal, and the PDSCH scheduled by the downlink control information may include the time slot of the PDSCH and the interval k1 between the uplink control channel and the downlink control channel. After the time domain configuration information is configured according to DCI-0 and DCI-1, if the TRP corresponding to PUCCH R0 and PUCCH R2 is different from the TRP corresponding to PUCCH R1 and PUCCH R3, then PUCCH R0 and PUCCH R2 can be in the time domain Spaced distribution, PUCCH R1 and PUCCH R3 are spaced apart in the time domain. If the TRPs corresponding to PUCCH R0 and PUCCH R1 are the same, and the TRPs corresponding to PUCCH R2 and PUCCH R3 are the same, then PUCCH R0 and PUCCH R1 can be continuously distributed in the time domain, and PUCCH R2 and PUCCH R3 can be continuously distributed in the time domain.

Through the above two configuration manners, PUCCHs on different TRPs can be scheduled in an orderly manner, and the reliability of repeated transmission can be improved.

In practical applications, before sending the N PUCCHs that are repeatedly transmitted, the following further steps are included:

Receive M DCIs, each DCI includes first configuration information corresponding to a part of the PUCCHs in the N PUCCHs, the TRPs corresponding to the part of the PUCCHs are the same, the M is an integer greater than or equal to 2, and the N is Integer greater than or equal to 2.

For a network-side device, such as a TRP, before receiving the partial PUCCH in the N physical uplink control channels PUCCH that are repeatedly transmitted, the method according to the embodiment of the present disclosure further includes:

Sending DCI, where the DCI includes first configuration information corresponding to a part of the PUCCHs in the N PUCCHs, the receiving and transmitting reception points TRP corresponding to the part of the PUCCHs are the same, and each of the M DCIs corresponds to the Part of the PUCCHs in the N PUCCHs, the M is an integer greater than or equal to 2.

In this embodiment, N PUCCHs can be grouped to form M PUCCH groups, and the received TRP of each PUCCH group is the same. In this way, for each TRP, the same DCI can be used to schedule the PUCCH group corresponding to the TRP, which can improve the efficiency of information transmission; and for multiple TRPs transmitted repeatedly, since the PUCCH can contain different resources, The PUCCHs of different TRPs can be scheduled through different DCIs, so that the resources acquired by different TRPs can be different, and the flexibility of resource scheduling can be improved.

Further, the first configuration information includes time domain configuration information, which is used to configure the N PUCCHs to be sequentially distributed in units of PUCCH groups in the time domain, or to configure the N PUCCHs to be Adjacent PUCCHs in the time domain belong to different groups. That is to say, in units of PUCCH groups, the PUCCH groups are sequentially distributed in the time domain, or the PUCCH groups are distributed at intervals in the time domain.

In the second manner, from the perspective of the spatial relationship configuration of the PUCCH, the reliability of repeated transmission is improved, and the description is as follows.

Before the sending of the N PUCCHs that are repeatedly transmitted, the method further includes:

Receive 1 MAC CE (Media Access Control Control Element, a control unit of media access control); the MAC CE carries L second configuration information, and each second configuration information is used to indicate a part of the N PUCCHs The spatial relationship parameter of the PUCCH, the L is an integer greater than or equal to 2.

For a network-side device, such as a TRP, in the method according to the embodiment of the present disclosure, before the N physical uplink control channels PUCCH that are repeatedly transmitted, the method further includes:

Send 1 MAC CE; the MAC CE carries L second configuration information, each second configuration information is used to configure the spatial relationship parameters of some PUCCHs in the N PUCCHs, and the L is greater than or equal to 2 Integer.

In this embodiment, one MAC CE may be used to activate spatial relationship parameters of multiple PUCCHs, wherein the spatial relationship parameters may include parameters for controlling beam directions, power control parameters for power control, and the like.

Further, the N PUCCHs activated by the MAC CE can also be configured in the following two ways in the time domain:

The first one is continuous transmission of PUCCHs corresponding to the same second configuration information in the time domain.

This method can also be called sequential mapping, that is to say, the partial spatial relationship parameters activated first and the partial spatial relationship parameters activated later are configured in sequence according to the sequence. , to determine the spatial relationship parameters that are activated first and then activated later.

The second is that in the time domain, the second configuration information corresponding to adjacent PUCCHs is different.

This method can also be called cyclic mapping, that is, the spatial relationship parameters that are activated in sequence can be configured at intervals. For example, alternately configure the spatial relationship parameters for the activation of the MAC CE by mapping the odd-numbered times and the spatial relationship parameters for the activation of the MAC CE for the even-numbered mappings.

From the perspective of the network side device, the MAC CE is used to configure the N PUCCHs as: in the time domain, the PUCCHs corresponding to the same second configuration information are continuously transmitted; or, in the time domain, The second configuration information corresponding to adjacent PUCCHs is different.

In the specific embodiment of the present disclosure, PUCCHs corresponding to different TRPs correspond to different spatial relationship configurations, and PUCCHs corresponding to the same TRP correspond to the same spatial relationship configuration, thereby improving the reliability of information transmission.

In order to facilitate the understanding of the above-mentioned embodiments, examples are given below with reference to the accompanying drawings.

Referring to FIG. 5, FIG. 5 shows a field information table included in a MAC CE scheduling PUCCH, and the MAC CE is used to schedule PUCCHs of two TRPs (two TRPs are taken as an example here). The field information table includes 4 rows of fields, and each row includes 8 bits. The first line includes the reserved bit R, the serving cell ID (Serving Cell ID) and the bandwidth identification (BWP ID); the second line includes the physical uplink control channel resource ID (PUCCH resource ID), and each PUCCH resource ID corresponds to a group of PUCCH IDs. Two spatial relation information identifiers; the third row includes a field for carrying the spatial relation information identifier (Spatial Relation Info ID), and reserved bits R and field C, and the fourth row includes two reserved bits R and is used to carry the spatial relation Fields for information identification.

Using the spatial relationship information carried by the above MAC CE, the spatial relationship information of the PUCCH can be configured. Referring to FIG. 6, FIG. 6 shows a configuration manner of the PUCCH in the time domain.

Among them, as shown in the time slot map corresponding to the first row of the PUCCH transmission, when the spatial relationship parameters of the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot1R1 are the same, the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot1R1 can be in the time domain. Continuous transmission; the spatial relationship parameters of the PUCCH corresponding to slot2R2 and the PUCCH corresponding to slot3R3 are the same, and the PUCCH corresponding to slot2R2 and the PUCCH corresponding to slot3R3 can also be continuously transmitted in the time domain. After the configuration above, the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot1R1 can be configured with the same set of spatial relationship parameters, and can correspond to TRP11; the PUCCH corresponding to slot2R2 and the PUCCH corresponding to slot3R3 can be configured with another set of spatial relationship parameters. and corresponds to TRP12.

As shown in the transmission of PUCCH on the time slot diagram corresponding to the second row, when the spatial relationship parameters of the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot1R1 are different, the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot1R1 can be transmitted at intervals; When the spatial relationship parameters of the PUCCH and the PUCCH corresponding to the slot3R3 are different, the PUCCH corresponding to the slot2R2 and the PUCCH corresponding to the slot3R3 may also be transmitted at intervals in the time domain. After the configuration above, the PUCCH corresponding to slot0R0 and the PUCCH corresponding to slot2R2 can be configured with the same set of spatial relationship parameters, and can correspond to TRP11; the PUCCH corresponding to slot1R1 and the PUCCH corresponding to slot3R3 can be configured with another set of spatial relationship parameters. and corresponds to TRP12.

When considering the DCI and spatial relationship parameters corresponding to the PUCCH at the same time, different PUCCHs may correspond to different DCI and spatial relationship parameters. Taking two DCIs ( DCI0 and DCI1 ) and two sets of spatial relationship parameters (spatial relationship 0 and spatial relationship 1 ) to schedule the PUCCH for four repeated transmissions as an example. The DCI and spatial relationship parameters corresponding to PUCCH0, PUCCH1, PUCCH2, and PUCCH3 can be combined in various ways as shown in Figure 7. Figure 7 is only an example of a partial combination, and other more combinations can be obtained in the above-mentioned way. Exhaustive examples are not given here.

Wherein, in combination 1, the DCI and spatial relationship corresponding to PUCCH0 and PUCCH2 are the same, and the DCI and spatial relationship corresponding to PUCCH1 and PUCCH3 are also the same. This combination mode can adopt the interval transmission of PUCCH in the time domain. In combination 4, the DCI and spatial relationship corresponding to PUCCH0 and PUCCH1 are the same, and the DCI and spatial relationship corresponding to PUCCH2 and PUCCH3 are also the same. This combination mode can adopt continuous transmission of PUCCH in the time domain. For a specific transmission manner, reference may be made to the descriptions in the foregoing embodiments, and details are not repeated here.

In practical applications, this embodiment may also include:

Before the sending the N PUCCHs that are repeatedly transmitted to the N TRPs for joint transmission, the method further includes:

Receive 1 MAC CE; the MAC CE carries L groups of second configuration information, each group of second configuration information corresponds to a PUCCH group composed of some PUCCHs in the N PUCCHs, and each group of second configuration information includes space At least one of configuration information and power control parameters, the L is an integer greater than or equal to 2.

Further, the PUCCH group can also be configured in the following ways:

The first type: in the time domain, adjacent PUCCHs belong to different PUCCH groups;

The second type: in the time domain, the N PUCCHs are sequentially distributed in groups;

The third type: the L is equal to the N, and the received TRPs of the PUCCHs in each PUCCH group are the same.

In the embodiment of the present disclosure, the spatial relationship parameter of the PUCCH is determined by the configuration information carried by the MAC CE, and the terminal can flexibly configure the spatial relationship parameter according to the TRP corresponding to the PUCCH, so that the PUCCH sent to the same TRP can use the same set of configuration information and be sent to different The PUCCH of the TRP uses different configuration information, and can flexibly configure information according to parameters such as the transmission environment of the TRP, thereby improving the reliability of repeated transmission.

When the MAC CE configuration is not used, the terminal can configure the default spatial relationship for the PUCCH in the following two ways:

The first is the CORESET pool index parameter configured according to the CORESET where the DCI of the scheduled PUCCH is located. The spatial relationship of the PUCCH is predefined as follows: according to the QCL (Quasi Co-Location, Quasi-Co-location) assumption or the configured Quasi-Co-location Type D (QCL-TypeD) is determined.

The second is the CORESET pool index parameter configured according to the CORESET where the DCI of the scheduled PUCCH is located. The path loss reference signal of the PUCCH is predefined as: a reference corresponding to the QCL assumption of a CORESET in the CORESET configured with the same index parameter. signal or the reference signal corresponding to the configured QCL-TypeD.

Wherein, one CORESET in the CORESETs configured with the same index parameter is the CORESET with the smallest identification among the CORESETs configured with the same index parameter.

From the perspective of network-side devices, the default spatial relationship can be configured for PUCCH in the following ways:

The first is to predefine the spatial relationship of the physical uplink control channel PUCCH according to the control resource set CORESET pool index parameter configured by the control resource set CORESET where the downlink control information DCI of the physical uplink control channel PUCCH is scheduled as follows: The quasi-co-located QCL assumption or the configured quasi-co-located type D (QCL-TypeD) configuration of a control resource set CORESET in the control resource set CORESET with the same index parameter;

The second is to predefine the path loss reference signal of the physical uplink control channel PUCCH according to the control resource set CORESET pool index parameter configured by the control resource set CORESET where the downlink control information DCI of the physical uplink control channel PUCCH is scheduled as: According to the quasi-co-located QCL of one control resource set CORESET configured with the same index parameter, the corresponding reference signal or the configured reference signal corresponding to the quasi-co-located type D (QCL-TypeD) is assumed.

Wherein, one control resource set CORESET in the control resource sets CORESET configured with the same index parameter is the control resource set CORESET with the smallest identification among the control resource sets CORESET configured with the same index parameter.

In this embodiment, the above parameters may be configured in a sequential or cyclic manner according to the TRP corresponding to the PUCCH. For example, in the part of PUCCH that is transmitted first, the pre-defined spatial relationship of PUCCH and the pre-defined path loss reference signal are associated with the reference signal of QCL-TypeD or QCL hypothesis that identifies the smallest CORESET in coreset Pool Index-r16=0, and the reference signal is transmitted later In the part of PUCCH, the pre-defined spatial relationship of PUCCH and the pre-defined path loss reference signal are associated with the reference signal of QCL-TypeD or QCL hypothesis that identifies the smallest CORESET in coreset Pool Index-r16=1. Or, for the pre-defined spatial relationship and pre-defined path loss reference signal of PUCCH, the PUCCH mapping coresetPoolIndex-r16=0 for odd-numbered transmissions identifies the QCL-TypeD or QCL hypothesis of the smallest CORESET reference signal, and the PUCCH mapping for even-numbered transmissions CoresetPoolIndex-r16=1 identifies the QCL-TypeD of the smallest CORESET or the reference signal of the QCL hypothesis.

When this embodiment is specifically implemented, the terminal can also configure a default spatial relationship for the PUCCH in the following manner:

The N PUCCHs form M PUCCH groups, the receiving TRPs of the PUCCHs in each PUCCH group are the same, and the first configuration information includes time domain configuration information, used to configure the N PUCCHs to be, in the time domain, Distributed sequentially in units of PUCCH groups, and the spatial relationship of the PUCCH groups is configured to be determined according to the QCL-TypeD of the first CORESET corresponding to the received TRP;

or

The N PUCCHs form M PUCCH groups, the receiving TRPs of the PUCCHs in each PUCCH group are the same, and the first configuration information includes time domain configuration information, used to configure the N PUCCHs to be, in the time domain, Distributed sequentially in units of PUCCH groups, and the reference signals used for path loss calculation in the PUCCH groups are configured as reference signals corresponding to the QCL assumption of the received TRP;

or

The N PUCCHs form M PUCCH groups, the receiving TRPs of the PUCCHs in each PUCCH group are the same, and the first configuration information includes time domain configuration information, used to configure the N PUCCHs to be, in the time domain, Adjacent PUCCHs belong to different groups, and the spatial relationship of the PUCCH groups is configured to be determined according to the QCL-TypeD of the first CORESET corresponding to the received TRP;

or

The N PUCCHs form M PUCCH groups, the receiving TRPs of the PUCCHs in each PUCCH group are the same, and the first configuration information includes time domain configuration information, used to configure the N PUCCHs to be, in the time domain, Adjacent PUCCHs belong to different groups, and the reference signals used for path loss calculation corresponding to the PUCCH groups are configured as reference signals for receiving the QCL assumption of the TRP.

In this embodiment, the spatial relationship and the path loss reference signal can be predefined according to various principles, which can improve the flexibility of information configuration and improve the reliability of repeated transmission.

The third way, from the way of determining the transmission power of the PUCCH, improves the reliability of transmission, which is described as follows:

The first configuration information includes a TPC command, which is used to determine the transmission power of the PUCCH scheduled by the DCI where it is located.

In this embodiment, the TPC command indicated in the DCI of the scheduling PUCCH may be used to control the transmission power of the PUCCH. For example, the PUCCH scheduled by the DCI associated with coresetPoolIndex-r16=0 uses the TPC command indicated in the DCI with coresetPoolIndex-r16=0 for power control.

This method can also be understood from the perspective of the network side device that the first configuration information includes a TPC command, which is used to configure the transmission power of the PUCCH scheduled by the DCI.

In a specific embodiment of the present disclosure, PUCCHs corresponding to different TRPs correspond to different TPC commands, and PUCCHs corresponding to the same TRP correspond to the same TPC command.

Determining the transmission power of the PUCCH by the TPC command indicated in the DCI scheduling the PUCCH can control the transmission power more accurately and improve the reliability of repeated transmission.

The reliability of PUCCH transmission can be further improved by any one of the above three manners or a combination of multiple manners.
