Document Type and Number:
WIPO Patent Application WO/2023/050302
Kind Code:
A1
Abstract:
Methods and apparatuses for handling collision for aperiodic SRS triggering are disclosed. A method at an UE comprises receiving one or multiple DCIs triggering multiple SRS resources to be transmitted in at least one same symbol; determining which SRS resource among the multiple triggered SRS resources that collide in the at least one same symbol has the highest priority according to at least one of the priority rules including priority rule #1: based on the usage of each of the triggered SRS resources that collide, priority rule #2: based on a version of the DCI triggering each of the triggered SRS resources that collide, priority rule #3: based on the triggering time of the DCI triggering each of the triggered SRS resources that collide, priority rule #4: based on the slot offset configured to each of the triggered SRS resources that collide, priority rule #5: based on SRS resource ID of each of the triggered SRS resources that collide, and priority rule #6: based on SRS resource set ID associated with each of the triggered SRS resources that collide; and transmitting, in the at least one same symbol, the SRS resource determined to have the highest priority.
