US 2026/0128935 A1 · SRS ENHANCEMENT FOR INTERFERENCE RANDOMIZATION

Abstract

Apparatuses and methods for SRS enhancement for interference randomization in wireless networks. A method performed by a user equipment (UE) includes receiving a configuration about a sounding reference signal (SRS) resource. The configuration includes information about a cyclic shift offset ∈ { 0 , 1 , … , n SRS CS , max - 1 } and a transmission-comb offset ∈ { 0 , 1 , … , k TC - 1 } · n SRS CS , max is a maximum number of cyclic shifts and KTC is a transmission comb number. The SRS resource is associated with a plurality of antenna ports. The method further includes determining, based on a first pseudo-random sequence, the cyclic shift offset for each of the plurality of antenna ports; determining, based on a second pseudo-random sequence, the transmission-comb offset for each of the plurality of antenna ports; and transmitting, based on the cyclic shift offset and the transmission-comb offset, the SRS resource.

Dependent claims

A user equipment (UE) in a communication system, the UE comprising:

a transceiver configured to receive, via higher layer signaling, a configuration of a sounding reference signal (SRS) resource, wherein the configuration of the SRS resource includes a first higher parameter configuring cyclic shift hopping for the SRS resource;
and
a processor operably coupled with the transceiver, the processor configured to:
determine an SRS sequence based on a cyclic shift hopping parameter for the cyclic shift hopping;
and
map the SRS sequence to resource elements (REs) within the SRS resource,
wherein the transceiver is further configured to perform an SRS transmission based on the REs to which the SRS sequence is mapped.
