US 11,606,814 B2 · Uplink collision handling

Abstract

Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).

Dependent claims

A method for wireless communications at a user equipment (UE), comprising:

determining a first priority level associated with first uplink information based at least in part on a type of channel state information report for the first uplink information, wherein the type of channel state information report is classified according to a time-based resource allocation for transmission of the first uplink information;
determining a collision resolution configuration for transmission of the first uplink information based at least in part on the first priority level, wherein the collision resolution configuration comprises resolving collisions across channels associated with a same priority level before resolving collisions across priority levels;
and
transmitting the first uplink information in accordance with the time-based resource allocation and the collision resolution configuration.

1 more element

An apparatus for wireless communications at a user equipment (UE), comprising:

a processor,
memory coupled with the processor;
