US 2026/0020072 A1 · TECHNIQUES FOR RANDOM ACCESS RESOURCE SELECTION IN WIRELESS COMMUNICATIONS

Abstract

Methods, systems, and devices for wireless communications are described in which a UE may be configured with random access resource selection criteria that can steer the UE to use either a first set of random access resources or a second set of additional random access resources that may be dynamically activated or deactivated. The selection criteria may be a probability that is assigned to each set of resources, and the UE may perform random selection based on a weighting that is given by the probability. Additionally, or alternatively, the selection criteria may include a reference signal receive power (RSRP) associated with the different sets of random access resources, and the second set of random access resources may be selectable by a UE only if a RSRP of a reference signal associated with the second set of random access resources is above a threshold value.

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 random access selection information that indicates one or more parameters for selection of a random access channel resource from one of a first set of random access channel resources or a second set of random access channel resources, wherein the first set of random access channel resources have a static time domain configuration over a first time period and the second set of random access channel resources are dynamically adaptable in the time domain over the first time period;
select a first random access channel resource from one of the first set of random access channel resources or the second set of random access channel resources based at least in part on the random-access selection information;
and
transmit a first random access channel message via the first random access channel resource.
