Scheduling collision handling with multiple transmit receive points
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP. The UE may detect a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time. The UE may selectively transmit one or more of the first scheduled communication or the second scheduled communication based at least in part on the detecting the scheduling collision. Numerous other aspects are described.
1 . A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP;
detect a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time;
select an additional transmission resource; and
transmit the first scheduled communication and the second scheduled communication using the additional transmission resource.
2 . The UE of claim 1 , wherein the UE is configured to expect that scheduling collisions can occur between multiple TRPs.
3 . The UE of claim 1 , wherein the one or more processors, to detect the scheduling collision, are configured to detect the scheduling collision further based at least in part on a capability of the UE for handling messages that overlap in time.
4 . The UE of claim 1 , wherein the first scheduling message includes a first downlink control information (DCI), and the second scheduling message includes a second DCI.
5 . The UE of claim 1 , wherein the first scheduling message includes a first radio resource control (RRC) message, and the second scheduling message includes downlink control information (DCI).
6 . The UE of claim 5 , wherein the DCI overrides an earlier RRC message from the second TRP that scheduled a communication.
7 . The UE of claim 1 , wherein the first scheduling message includes a first radio resource control (RRC) message, and the second scheduling message includes a second RRC message.
8 . A method of wireless communication performed by a user equipment (UE), comprising:
receiving a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP;
detecting a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time;
selecting an additional transmission resource; and
transmitting the first scheduled communication and the second scheduled communication using the additional transmission resource.
9 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
receive a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP;
detect a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time;
select an additional transmission resource; and
transmit the first scheduled communication and the second scheduled communication using the additional transmission resource.
10 . An apparatus for wireless communication, comprising:
means for receiving a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP;
means for detecting a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time;
means for selecting an additional transmission resource; and
means for transmitting the first scheduled communication and the second scheduled communication using the additional transmission resource.
