US 12,757,132 B2 · Automatic gain control designs for sidelink feedback

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment may receive a signal in an automatic gain control resource and may receive a physical sidelink feedback channel message based on a gain for reception of the first physical sidelink feedback channel message, where the gain is based on receiving the signal. In some aspects, the first physical sidelink feedback channel message may be one of a set of physical sidelink feedback channel messages time-division multiplexed over a set of contiguous time resources. Additionally, or alternatively, the user equipment may receive a sidelink message after receiving the physical sidelink feedback channel message using a second gain, where the second gain is based on receiving a second signal in a second automatic gain control resource that occurs before the first automatic gain control resource.

Dependent claims

An apparatus, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and operable to execute the code to cause the one or more processors, individually or collectively, to:
receive a signal in an automatic gain control (AGC) resource;
and
receive a first physical sidelink feedback channel (PSFCH) message based at least in part on a gain for reception of the first PSFCH message, wherein the gain for reception of the first PSFCH message is based at least in part on receiving the signal, wherein the first PSFCH message is one of a plurality of PSFCH messages that are time-division multiplexed over a plurality of contiguous time resources, wherein a starting time resource of the plurality of contiguous time resources is contiguous with the AGC resource, and wherein a first time period spanned by the AGC resource is greater than a second time period spanned by each PSFCH message of the plurality of PSFCH messages.
