Description

Method and apparatus for multi-transmission receiving point transmission

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for multi-transmission and multi-reception point transmission.

Background

In a Transmission Reception Point (TRP) Transmission technology, multiple TRPs may transmit the same data stream to the same terminal device to improve Transmission reliability, or multiple TRPs may transmit different data streams to the same terminal device to improve Transmission effectiveness.

Currently, multiple TRP transmission schemes are mainly classified into a single Physical Downlink Control Channel (PDCCH) and multiple PDCCHs. For a single PDCCH, multiple TRPs transmit the same or different data streams to the same terminal device on the same time-frequency resource. For multiple PDCCHs, multiple TRPs may transmit the same or different data streams to the same terminal device on the same or different time-frequency resources.

When multiple TRPs transmitting TRPs belong to the same cell, Synchronization Signal Blocks (SSBs) of the TRPs occupy the same frequency resources in a time-division multiplexing manner. When multiple TRPs for multiple TRP transmission belong to different cells, the SSB of each TRP typically occupies different video resources. Each TRP performing multiple TRP transmission performs rate matching of data streams according to the SSB sent by itself, which may cause the SSB of one TRP and a Physical Downlink Shared Channel (PDSCH) of another TRP to occupy the same time-frequency resource, affecting the synchronization performance of the TRP and the reliability of PDSCH transmission.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a method for multiple transmit receive points TRP transmission according to one embodiment of the present invention. The method shown in fig. 1 may be performed by a first TRP. As shown in fig. 1, the method comprises:

s110, shared information is determined, wherein the shared information is used for determining a target rate matching pattern used for performing rate matching on a Physical Downlink Shared Channel (PDSCH), the target rate matching pattern is related to a first rate matching pattern and a second rate matching pattern, the first rate matching pattern corresponds to first non-data information of a first TRP, the second rate matching pattern corresponds to second non-data information of a second TRP, and the second TRP and the first TRP respectively send the PDSCH to a target terminal device.

The first non-data information and the second non-data information in S110 may be understood as information other than data information. For example, the Reference Signal may be a Synchronization Signal Block (SSB), a Channel State Information Reference Signal (CSI-RS), or a Demodulation Reference Signal (DMRS).

S120, sending the shared information to the second TRP.

It is to be appreciated that, after the second TRP receives the shared information, a target rate matching pattern for rate matching the PDSCH may be determined according to the shared information.

In S120, the way for the first TRP to send the shared information to the second TRP may be: (1) when the first TRP and the second TRP belong to the same cell, transmitting through an air interface between the first TRP and the second TRP; (2) when the first TRP belongs to cell 1, the second TRP belongs to cell 2, and cell 1 and cell 2 belong to the same network device, transmitting through an interface between cell 1 and cell 2 (e.g., an Xn interface); (3) when the first TRP belongs to cell 1, the second TRP belongs to cell 2, and cell 1 belongs to network device 1, and cell 2 belongs to network device 2, the TRP is transmitted through an interface between network device 1 and network device 2 (it can be understood that the TRP is transmitted through an interface between cell 1 and a higher-level network element of cell 2).

Optionally, in some embodiments, the first non-data information in S110 includes a first synchronization signal block SSB, and the second non-data information includes a second SSB. Here, the first SSB may be a partial or full SSB transmitted by the first TRP, and the second SSB may be a partial or full SSB transmitted by the second TRP.

As an example, in the case that the first non-data information includes a first SSB and the second non-data information includes a second SSB, the first rate matching pattern includes time-frequency resources where the first SSB is located; the shared information comprises first indication information, and the first indication information is used for indicating the time frequency resource where the first SSB is located.

It can be understood that, if the first TRP and the second TRP belong to the same cell, the SSBs of the first TRP and the second TRP occupy the same frequency resource in a time division multiplexing manner, and therefore the first indication information may indicate the time-frequency resource of the first SSB by indicating the relative position (SSB-position in Burst) of the first SSB in its corresponding Synchronization Signal Burst Set (SSBs). Or the first indication information indicates the time-frequency resources of the first SSB by indicating the relative position of the first SSB in its corresponding SSBs and the corresponding frequency resources.

As another example, in the case where the first non-data information includes a first SSB and the second non-data information includes a second SSB, the target rate matching pattern includes a union of a first time-frequency resource in which the first SSB is located and a second time-frequency resource in which the second SSB is located; the shared information includes second indication information, and the second indication information is used for indicating a union of the first time-frequency resource and the second time-frequency resource.

That is, the first TRP determines a union of time-frequency resources occupied by the first SSB and the second SSB, and informs the union to the second TRP through the second indication information.

It is to be understood that, if there are overlapping time-frequency resources for the first time-frequency resource and the second time-frequency resource, the second indication information indicates the overlapping time-frequency resources and the non-overlapping time-frequency resources. For example, the first time-frequency resource includes time-frequency resource 1, time-frequency resource 2, and time-frequency resource 3, the second time-frequency resource includes time-frequency resource 2, time-frequency resource 3, and time-frequency resource 5, and the second indication information indicates time-frequency resource 1, time-frequency resource 2, time-frequency resource 3, and time-frequency resource 5. The second indication information indicates the first time frequency resource and the second time frequency resource if there is no overlap between the first time frequency resource and the second time frequency resource. For example, the first time-frequency resource includes time-frequency resource 1, time-frequency resource 2, and time-frequency resource 3, the second time-frequency resource includes time-frequency resource 4, time-frequency resource 5, and time-frequency resource 6, and the second indication information indicates time-frequency resource 1, time-frequency resource 2, time-frequency resource 3, time-frequency resource 4, time-frequency resource 5, and time-frequency resource 6.

Optionally, as an example, when the frequency domain resources where the first SSB and the second SSB are located are the same, the second indication information specifically indicates a union of the first time-frequency resource and the second time-frequency resource, and may indicate a relative position of the first SSB and the second SSB in the SSSB. For example, if the relative position of the first SSB in its corresponding SSSB is represented by "1" in [ 10010010010 ] and the relative position of the second SSB in its corresponding SSSB is represented by "1" in [01001001], the second indication information indicates that the union of the first time-frequency resource and the second time-frequency resource is in the form of [11011011 ].

Further, when the frequency domain resources where the first SSB and the second SSB are located are the same or different, the second indication information indicates, in addition to the relative positions of the first SSB and the second SSB in the SSSB, the frequency domain resources corresponding to the first SSB and the second SSB.

On the basis of all the above embodiments, the shared information further includes at least one of identification information of the first TRP and identification information of the target terminal device. Here, the identification information of the first TRP may be, for example, an identification of a Control Resource Set (CORESET) corresponding to the first TRP, and the identification information of the target terminal device may be an identification (Identifier, ID) of the target terminal device or a Cell Radio network temporary Identifier (C-RNTI).

Optionally, in some embodiments, the method shown in fig. 1 further includes: and carrying out rate matching on the PDSCH sent to the target terminal equipment according to the target rate matching pattern.

In order for the target terminal device to successfully receive the PDSCH from the first TRP, the first TRP needs to send information related to a target rate matching pattern of the PDSCH to the target terminal device, so that the target terminal device can determine the target rate matching pattern of the PDSCH from the first TRP and perform de-rate matching on the PDSCH from the first TRP based on the target rate matching pattern.

Optionally, in some embodiments, in a case that the first non-data information includes a first SSB, the second non-data information includes a second SSB, the first rate matching pattern includes time-frequency resources where the first SSB is located, and the second rate matching pattern includes time-frequency resources where the second SSB is located, the method shown in fig. 1 further includes:

sending a System Information Block (SIB) 1 to a target terminal device, where the SIB1 includes third indication Information, and the third indication Information is used to indicate a time-frequency resource where the first SSB is located;

and sending a first Radio Resource Control (RRC) signaling to a target terminal device, wherein the first RRC signaling comprises fourth indication information, and the fourth indication information is used for indicating the time-frequency Resource where the second SSB is located.

It is to be appreciated that the third indication information may be carried in the SSB-positioninginburst field in SIB1, the third indication information indicating the relative position of the first SSB in its corresponding SSSB. The fourth indication Information may be carried in a ServingCellConfigCommon cell (IE) in RRC signaling, and the fourth indication Information indicates a relative position of the second SSB in its corresponding SSSB and corresponding frequency domain resources. The first RRC signaling may be considered as a new RRC signaling different from the RRC signaling in the existing protocol for indicating a rate matching pattern of non-data information of other TRPs, and a format of a specific rate matching pattern is configured by the RRC signaling.

Alternatively, the method shown in fig. 1 further includes:

sending a second RRC signaling to a target terminal device, wherein the second RRC signaling comprises fifth indication information, and the fifth indication information is used for indicating the time-frequency resource where the first SSB is located;

and sending a third RRC signaling to the target terminal equipment, wherein the third RRC signaling comprises sixth indication information, and the sixth indication information is used for indicating the time-frequency resource where the second SSB is located.

It is to be understood that the fifth indication information may be carried in servingcellconfigcommon in the third RRC signaling, the fifth indication information indicates a relative position of the first SSB in its corresponding SSSB or further indicates frequency-domain resources corresponding to the first SSB, and the sixth indication information may indicate a relative position of the second SSB in its corresponding SSSB or further indicates frequency-domain resources corresponding to the second SSB.

For example, as shown in fig. 2, in an inter-cell multi-TRP transmission scenario, a terminal device receives pdsch from TRP #1 and TRP #2, respectively, wherein TRP #1 belongs to cell 1, TRP #2 belongs to cell 2. TRP #1 periodically transmits three SSBs SSB #0, SSB #3, and SSB #6, respectively corresponding to three beams, TRP #2 periodically transmits two SSBs SSB #0 and SSB #2, respectively corresponding to two beams, TRP #1 shares C-TRP #1 frequency information (e.g., frequenecyinfd L field in servingcellconfigcommon) of the terminal device and a time domain position SSB-posisionburst-TRP #1 [10010 ] (or understood as a rate matching pattern of the SSB) in the SSB of TRP #1 and a time domain-posisionsilnfe [10010 ] (or a rate matching pattern of the SSB) shares TRP #2 with TRP #2, TRP #2 share frequency information [ e.g. in the frequency domain of TRP #1, TRP #2, TRP #1, TRP # 2.

Further, the TRP #1 notifies the terminal device of the time-frequency resource (the rate matching pattern of the SSB of TRP #1) in which the SSB of TRP #1 is located and the time-frequency resource (the rate matching pattern of TRP # 2) in which the SSB of TRP #2 is located, and the specific notification method includes:

the first method is as follows:

TRP #1 indicates the rate matching pattern of the SSB of TRP #1 by SSB-positioninsburst in SIB1, [10010010] and the rate matching pattern of the SSB of TRP #2 by servingcellconfigcommon ie in RRC signaling corresponding to TRP # 2. The format of the ServingCellConfigCommon IE corresponding to TRP #2 may be, for example:

ServingCellConfigCommon#2＝{

…

physCellId(Cell#2ID)

downlinkConfigCommon(for TRP#2)

ssb-PositionsInBurst(ssb-PositionsInBurst-TRP#2＝[10100000])

…

}

phySCellId in ServinCellConfigCommon IE corresponding to TRP #2 indicates the ID of cell 2, SSB-PositionInBurst indicates the relative position of the SSB of TRP #2 in its corresponding SSSB.

Correspondingly, when determining the target rate matching pattern corresponding to the PDSCH, the terminal device not only follows the rate matching pattern of the SSB of TRP #1 indicated in SIB1, but also follows the rate matching pattern of the SSB of TRP #2 indicated in ServingCellConfigCommon #2 in RRC signaling.

The second method comprises the following steps:

the rate matching pattern of the SSB of TRP #1 is indicated by a ServingCellConfigCommon IE corresponding to TRP #1 in one RRC signaling. The rate matching pattern of the SSB of TRP #2 is indicated by another ServingCellConfigCommon IE in the RRC signaling that corresponds to TRP # 2.

The format of the ServingCellConfigCommon IE corresponding to TRP #1 may be, for example:

ServingCellConfigCommon#1＝{

…

physCellId(Cell#1ID)

downlinkConfigCommon(for TRP#1)

ssb-PositionsInBurst(ssb-PositionsInBurst-TRP#1＝[10010010])

…

}

the format of the ServingCellConfigCommon IE corresponding to TRP #2 may be, for example:

ServingCellConfigCommon#2＝{

…

physCellId(Cell#2ID)

downlinkConfigCommon(for TRP#2)

ssb-PositionsInBurst(ssb-PositionsInBurst-TRP#2＝[10100000])

…

}

correspondingly, the terminal device, when determining the target rate matching pattern corresponding to the PDSCH, not only follows the rate matching pattern of the SSB of TRP #1 indicated in ServingCellConfigCommon #1, but also follows the rate matching pattern of the SSB of TRP #2 indicated in ServingCellConfigCommon # 2.

Optionally, in some embodiments, in a case that the first non-data information includes a first SSB, the second non-data information includes a second SSB, and the target rate matching pattern includes a union of a first time-frequency resource in which the first SSB is located and a second time-frequency resource in which the second SSB is located, the method shown in fig. 1 further includes:

and sending a fourth RRC signaling to the target terminal device, wherein the fourth RRC signaling comprises seventh indication information, and the seventh indication information is used for indicating the union of the first time-frequency resource and the second time-frequency resource.

For example, as shown in fig. 3, one terminal device receives PDSCH from TRP #1 and TRP #2, respectively. Wherein, TRP #1 and TRP #2 belong to the same Cell (Cell #1) and are respectively provided with CORESET #1 and CORESET #2, TRP #1 periodically transmits three SSBs SSB #0, SSB #3 and SSB # 6; TRP #2 periodically transmits three SSBs SSB #1, SSB #4 and SSB # 7. The TRP #1 shares the C-RNTI of the terminal equipment and the union of the time-frequency resources where the SSBs of the TRP #1 and the TRP #2 are located to the TRP #2, for example, the TRP #1 indicates the union of the time-frequency resources where the SSBs of the TRP #1 and the TRP #2 are located by indicating the relative positions (denoted as SSB-PositionsInburst-sum) of the SSBs of the TRP #1 and the TRP #2 in the SSSB. Wherein the content of the first and second substances,

SSB-PositionsInBurst-TRP #1 indicates the relative position of the SSB of TRP #1 in SSSB, SSB-PositionsInBurst-TRP #2 indicates the relative position of the SSB of TRP #2 in SSSB, ∪ indicates the gather and gather operation,

representing a binary modulo-binary addition operation.

TRP #1 and TRP #2 rate-match PDSCH addressed to a terminal device according to a rate matching pattern indicated by ssb-PositionsInBurst-sum. Meanwhile, the ssb-PositionsInBurst-sum is notified to the terminal equipment through the ssb-PositionsInBurst domain in the RRC signaling servingCellConfigCommon IE. Correspondingly, the terminal equipment receives the PDSCH according to the rate matching pattern indicated by the ssb-PositionInBurst-sum in the ssb-PositionInBurst domain in the RRC signaling servingCellConfigCommon IE.

Optionally, in some embodiments, the method shown in fig. 1 further includes:

and sending Downlink Control Information (DCI) to the target terminal device, where the DCI includes eighth indication Information and ninth indication Information, the eighth indication Information is used to indicate the first rate matching pattern, and the ninth indication Information is used to indicate the second rate matching pattern.

That is, the first TRP may notify the target terminal device of a first rate matching pattern corresponding to the first non-data information of the first TRP and a second rate matching pattern corresponding to the second non-data information of the second TRP through the DCI.

As an example, the rate matching indication field of the DCI carries the eighth indication information and the ninth indication information. That is, the Rate Matching Indicator (Rate Matching Indicator) field in the existing DCI (e.g., Format 1-1) may be extended, for example, to 4 bits, which correspond to the high-layer parameters ratemacchpattern group1, ratemacchpattern group2, ratemacchpattern group3, and ratemacchpattern group4 from high to low, respectively. Wherein, ratematchpatterntgroup 3 and ratematchpatterntgroup 4 are used for indicating rate matching patterns of other TRPs except the first TRP, and the rate matching patterns indicated by ratematchpatterntgroup 3 and ratematchpatterntgroup 4 are specifically configured by RRC signaling.

For example, a Rate Matching Indicator2 field is newly introduced, and the field may contain 2 bits, wherein the Most Significant Bit (MSB) of the 2 bits is used to indicate a ratematchpatternbroup 3, and the least Significant Bit (L east signfighter Bit, L SB) is used to indicate a ratematchpatternbroup 4, wherein, the Rate matchpatternbroup 3 and the Rate matchpatternbroup 4 are used to indicate the Rate Matching patterns of other TRPs than the first TRP, and the

RRC signaling patterns

3 and 4 indicate the RRC Rate Matching patterns of RRC groupcroup.

For example, as shown in fig. 4, one terminal device receives PDSCH from TRP #1 and TRP #2, respectively. The TRP #1 shares two rate matching patterns, namely a rate matching pattern (ratemacchpattern group)1-1 and a rate matching pattern (ratemacchpattern group)1-2, with the TRP #2 shares two rate matching patterns, namely a rate matching pattern (ratemacchpattern group)2-1 and a rate matching pattern (ratemacchpattern group)2-2, with the TRP # 1. Wherein, the specific rate matching pattern of the rateMatchPattern group1-1, the rateMatchPattern group1-2, the rateMatchPattern group2-1 and the rateMatchPattern group2-2 is configured by RRC signaling.

The terminal equipment is configured to perform Rate matching on a PDSCH addressed to the terminal equipment according to the TRP #1 and the TREMATCHPatterGroup 1-1 and the RATEMATCHPatterGroup 1-2 of the Rate matching pattern of the TRP #2, and the RATEMATCHPatterGroup 2-1 and the RATEMATCHPatterGroup 2-2. meanwhile, the terminal equipment is dynamically indicated by DCI (containing a Rate matching indicator field of 2bit and a Rate matching indicator2 field of 2 bit) with the Rate matching pattern according to which the terminal equipment performs Rate matching on the PDSCH.

Correspondingly, the terminal equipment receives the PDSCH according to the Rate matching patterns indicated by the Rate matching indicator and the Rate matching indicator2 in the DCI.

The method of multi-TRP transmission according to one embodiment of the present invention is described in detail above from the first TRP side in conjunction with fig. 1 to 4, and the method of multi-TRP transmission according to another embodiment of the present invention is described in detail below from the second TRP side in conjunction with fig. 5. It should be noted that the interaction of the second TRP described from the second TRP side with the first TRP and the terminal device is the same as that described from the first TRP side, and the related description is appropriately omitted to avoid redundancy.

Fig. 5 is a schematic flow diagram of a method of multiple TRP transmission according to another embodiment of the present invention. The method of fig. 5 may be performed by a second TRP, as illustrated in fig. 5, the method comprising:

s210, receiving shared information from a first TRP, where the shared information is used to determine a target rate matching pattern used for performing rate matching on a PDSCH, where the target rate matching pattern is related to a first rate matching pattern and a second rate matching pattern, the first rate matching pattern corresponds to first non-data information of the first TRP, the second rate matching pattern corresponds to second non-data information of the second TRP, and the first TRP and the second TRP respectively send the PDSCH to a target terminal device;

s220, determining the target rate matching pattern according to the shared information.

The first non-data information and the second non-data information in S210 may be understood as information other than data information.
