US 12,707,484 B2 · Resource configuration for initial beam pairing for sidelink operation

Abstract

Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit reference signals bursts during an initial beam pairing (IBP) resource. In some examples, each reference signal burst may include an occasion for transmitting a reference signal of a set of reference signals. A second UE may measure the reference signals during the IBP resource and may determine a beam for sidelink communications with the first UE based on measuring the set of reference signals. The second UE may transmit a response message during a response occasion of the IBP resource, where each response occasion within the IBP resource corresponds to a respective reference signal of the set of reference signals. As such, the second UE may transmit a response message during a response occasion that corresponds to the reference signal associated with the selected beam, thereby indicating the selected beam to the first UE.

Dependent claims

A first 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 first UE to:
measure a set of reference signals during a first plurality of time occasions associated with an initial beam pairing resource, each time occasion of the first plurality of time occasions associated with a repetition of the set of reference signals, wherein the initial beam pairing resource is within a first subset of a frequency bandwidth associated with a sidelink bandwidth part or a sidelink resource pool and a second subset of the frequency bandwidth is available for sidelink communications by other UEs, and wherein the initial beam pairing resource comprises the first plurality of time occasions and a second plurality of time occasions for transmission of a response message, each time occasion of the second plurality of time occasions corresponding to a respective reference signal of the set of reference signals;
and
transmit a response message during a first time occasion of the second plurality of time occasions to indicate a beam for sidelink communications with a second UE, wherein the beam is associated with a reference signal corresponding to the first time occasion.
