Collision handling for multiple transmit receive points
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may receive an indication of a detection of a scheduling collision of a first scheduled communication of a first scheduling message from the first TRP and a second scheduled communication of a second scheduling message from a second TRP. The first TRP may back off from transmitting the first scheduled communication based at least in part on the indication. Numerous other aspects are described.
1 . A first transmit receive point (TRP) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
generate a configuration indicating an assignment of one or more collision sets, wherein the assignment allows for a scheduling collision in which a first communication scheduled by the first TRP overlaps in time with a second communication scheduled by a second TRP, and wherein the assignment is based at least in part on a collision probability and a trunking efficiency; and
transmit the configuration.
2 . The first TRP of claim 1 ,
wherein the one or more collision sets correspond to one or more of a set of resources for which scheduling collisions are allowed.
3 . The first TRP of claim 2 ,
wherein the configuration indicates the set of resources for which scheduling collisions are allowed via one or more of a bitmap, a start slot index, or an end slot index.
4 . The first TRP of claim 2 ,
wherein the configuration indicates one or more collision events for the set of resources for which scheduling collisions are allowed.
5 . The first TRP of claim 1 ,
wherein the configuration indicates a backoff counter that operates during a backoff timer and that delays transmission of the first communication.
6 . A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive a configuration indicating an assignment of one or more collision sets, wherein the assignment allows for a scheduling collision in which a first communication scheduled by a first transmit receive point (TRP) overlaps in time with a second communication scheduled by a second TRP, and wherein the assignment is based at least in part on a collision probability and a trunking efficiency; and
apply the configuration for a set of resources for which scheduling collisions are allowed and not applying the configuration for a set of resources for which scheduling collisions are not allowed.
7 . The UE of claim 6 ,
wherein the configuration indicates the set of resources for which scheduling collisions are allowed via one or more of a bitmap, a start slot index, or an end slot index.
8 . The UE of claim 6 ,
wherein the configuration indicates one or more collision events for the set of resources for which scheduling collisions are allowed.
9 . The UE of claim 6 ,
wherein the configuration indicates a backoff counter that operates during a backoff timer and that delays transmission of the first communication, and wherein the one or more processors are configured to start the backoff timer and the backoff counter upon detection of a scheduling collision.
10 . The UE of claim 6 ,
wherein the configuration indicates slots for one or more collision sets and one or more coordination sets.
11 . The first TRP of claim 1 ,
wherein the configuration further indicates another assignment of one or more coordination sets, wherein the one or more coordination sets correspond to one or more of another set of resources for which scheduling collisions are allowed.
12 . The first TRP of claim 11 ,
wherein the configuration indicates a starting slot and an ending slot for the one or more collision sets and a starting slot and an ending slot for the one or more coordination sets.
13 . The first TRP of claim 5 ,
wherein the one or more processors are configured to start the backoff timer and the backoff counter upon detection of a scheduling collision.
14 . 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 first transmit receive point (TRP), cause the the first TRP to:
generate a configuration indicating an assignment of one or more collision sets, wherein the assignment allows for a scheduling collision in which a first communication scheduled by the first transmit receive point (TRP) overlaps in time with a second communication scheduled by a second TRP, and wherein the assignment is based at least in part on a collision probability and a trunking efficiency; and
transmit the configuration.
15 . The non-transitory computer-readable medium of claim 14 ,
wherein the one or more collision sets correspond to one or more of a set of resources for which scheduling collisions are allowed.
16 . The non-transitory computer-readable medium of claim 15 ,
wherein the configuration indicates the set of resources for which scheduling collisions are allowed via one or more of a bitmap, a start slot index, or an end slot index.
17 . The non-transitory computer-readable medium of claim 15 ,
wherein the configuration indicates one or more collision events for the set of resources for which scheduling collisions are allowed.
18 . The non-transitory computer-readable medium of claim 14 ,
wherein the configuration indicates slots for one or more collision sets and one or more coordination sets.
19 . The non-transitory computer-readable medium of claim 14 ,
wherein the configuration indicates a backoff counter that operates during a backoff timer and that delays transmission of the first communication.
20 . The non-transitory computer-readable medium of claim 19 ,
wherein the one or more instructions further cause the first TRP to start the backoff timer and the backoff counter upon detection of a scheduling collision.
