US 2026/0039428 A1 · CROSSLINK INTERFERENCE MEASUREMENT FOR NON-TERRESTRIAL NETWORK SPECTRUM SHARING

Abstract

Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive multiple instances of an SRS from a second UE via consecutive symbols. The second UE may apply a cyclic shift and may add a cyclic prefix to each instance of the SRS such that the second UE periodically transmits the SRS across the symbols. The first UE may monitor the symbols during an observation window to receive a portion of a first instance of the SRS and a portion of a second instance of the SRS. In some examples, the combination of the portion of the first instance of the SRS and the portion of the second instance of the SRS may comprise a full period of an instance of the SRS. Accordingly, the first UE may measure interference using the SRS and transmit a report indicating interference information.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive at least a first portion of a first instance of a sounding reference signal in a first symbol, wherein the first symbol includes a first cyclic prefix;
and
receive at least a second portion of a second instance of the sounding reference signal in a second symbol that includes a second cyclic prefix and is consecutive to the first symbol in time, wherein the second instance of the sounding reference signal is based at least in part on a cyclic shift applied to the first instance of the sounding reference signal, the cyclic shift being based at least in part on a duration of the first cyclic prefix.

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
transmit a first instance of a sounding reference signal in a first symbol, wherein the first symbol includes a first cyclic prefix;
apply a cyclic shift to the first instance of the sounding reference signal, wherein the cyclic shift is based at least in part on a duration of the first cyclic prefix;
and
transmit a second instance of the sounding reference signal in a second symbol in accordance with the cyclic shift, wherein the second symbol includes a second cyclic prefix, and wherein the first symbol and the second symbol are consecutive in time.

4 more elements

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

receiving at least a first portion of a first instance of a sounding reference signal in a first symbol, wherein the first symbol includes a first cyclic prefix;
and
receiving at least a second portion of a second instance of the sounding reference signal in a second symbol that includes a second cyclic prefix and is consecutive to the first symbol in time, wherein the second instance of the sounding reference signal is based at least in part on a cyclic shift applied to the first instance of the sounding reference signal, the cyclic shift being based at least in part on a duration of the first cyclic prefix.
