Abstract

A user equipment (UE) is configured to communicate with one or more transmission and reception points (TRPs). The UE receives a sounding reference signal (SRS) resource set configuration including a first resource set corresponding to a first transmission and reception point (TRP) and a second resource set corresponding to a second TRP, receives a downlink control information (DCI) transmission including an SRS resource indicator (SRI) indicating (i) which resource from the first resource set should be selected for a first physical uplink shared channel (PUSCH) transmission to a first TRP, and (ii) which resource from the second resource set should be selected for a second PUSCH transmission to a second TRP and transmits the first PUSCH transmission to the first TRP and the second PUSCH transmission to the second TRP.

Claims (26)

1 . A processor of a user equipment (UE) configured to:

receive a first downlink control information (DCI) transmission scheduling a first physical uplink shared channel (PUSCH) transmission to be transmitted to a first transmission and reception point (TRP);

receive a second DCI transmission scheduling a second PUSCH transmission to be transmitted to a second TRP; and

receive configuration information from a base station of a wireless network related to a multi-TRP PUSCH transmission to the first TRP and the second TRP, wherein the configuration information configures the UE to partially cancel a portion of the second PUSCH transmission that overlaps with the first PUSCH transmission when a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

2 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to process the second DCI transmission and transmit the second PUSCH transmission if the second DCI is received after the transmission of the first PUSCH transmission.

3 . The processor of claim 1 , wherein the configuration information further comprises and out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to process the second DCI transmission and transmit the second PUSCH transmission if the second PUSCH transmission is scheduled after the transmission of the first PUSCH transmission.

4 . The processor of claim 1 , wherein the out of order configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to process the second DCI transmission and transmit the second PUSCH transmission regardless of when the second DCI is received or when the second PUSCH transmission is scheduled.

5 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to determine a transport block (TB) size for all PUSCH transmissions based on a first PUSCH transmission TB size.

6 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to determine a TB size for all PUSCH transmissions based on a last PUSCH transmission TB size.

7 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to interleave multiple PUSCH transmissions, and wherein the multiple PUSCH transmissions are non-overlapping.

8 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to cancel the second PUSCH transmission if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

9 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to cancel the first PUSCH transmission if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

10 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to partially cancel a portion of the first PUSCH transmission that overlaps with the second PUSCH transmission if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

11 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to partially cancel (i) a first portion of the first PUSCH transmission that overlaps with the second PUSCH transmission and (ii) a second portion of the second PUSCH transmission that overlaps with the first PUSCH transmission if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

12 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to cancel the first and second PUSCH transmissions if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.

13 . The processor of claim 1 , wherein the second PUSCH transmission is one of (i) a retransmission of the first PUSCH transmission or (2) not a retransmission of the first PUSCH transmission.

14 . The processor of claim 1 , wherein the configuration information further comprises an out of order configuration related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to interleave multiple PUSCH transmissions, and wherein the multiple PUSCH transmissions are non-overlapping.

15 . A processor of a base station configured to:

transmit, to a user equipment (UE), a first downlink control information (DCI) transmission scheduling a first physical uplink shared channel (PUSCH) transmission to be sent to a first transmission and reception point (TRP);

transmit, to the UE, a second DCI transmission scheduling a second PUSCH transmission to be transmitted to a second TRP; and

transmit an out of order configuration to the UE related to at least one of an out of order DCI transmission and an out of order PUSCH transmission, wherein the out of order configuration configures the UE to partially cancel a portion of the second PUSCH transmission that overlaps with the first PUSCH transmission if a collision occurs between the second PUSCH transmission and the first PUSCH transmission.
