US 2026/0095948 A1 · STATE-BASED RANDOM ACCESS RESOURCES FOR WIRELESS COMMUNICATION

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control information that indicates a first pool of random access (RACH) resources for UEs in a global navigation satellite system (GNSS)-available state and a second pool of RACH resources for UEs in a GNSS-less state. The second pool may include longer RACH preambles, longer RACH occasions, or a RACH preamble format associated with a greater quantity of propagation paths compared to the first pool. In response to the transitioning GNSS states during a RACH procedure, a UE may perform RACH failure operations, indicate the transition to a higher layer, get new RACH resources from a same or different pool, or any combination thereof. Additionally, or alternatively, the UE may indicate the transition, the different GNSS state, or both, to a non-terrestrial network entity in a RACH message of the RACH procedure or in dedicated signaling.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
a transceiver;
and
one or more processors coupled with the one or more memories and the transceiver, the one or more processors individually or collectively operable to execute the code to cause the UE to:
receive, via the transceiver, control information that indicates a first pool of random access resources for UEs in a first state with respect to a navigation satellite system and a second pool of random access resources for UEs in a second state with respect to the navigation satellite system, wherein at least one random access resource in the first pool of random access resources is not included in the second pool of random access resources or at least one random access resource in the second pool of random access resources is not included in the first pool of random access resources;
and
transmit, via the transceiver, a first random access message using a first random access resource, wherein whether the first random access resource is from the first pool of random access resources or the second pool of random access resources is based at least in part on a state of the UE with respect to the navigation satellite system.

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

receiving control information that indicates a first pool of random access resources for UEs in a first state with respect to a navigation satellite system and a second pool of random access resources for UEs in a second state with respect to the navigation satellite system;
and
transmitting a first random access message using a first random access resource, wherein whether the first random access resource is from the first pool of random access resources or the second pool of random access resources is based at least in part on a state of the UE with respect to the navigation satellite system.
