US 2026/0075640 A1 · POWER CONTROL FOR PHYSICAL RANDOM ACCESS CHANNEL TRANSMISSION AFTER ACTIVATION OF ADDITIONAL RANDOM ACCESS CHANNEL OCCASIONS

Abstract

Methods, systems, and devices for wireless communications are described. A network entity may schedule a first set of random access channel (RACH) occasions (ROs). The network entity may activate one or more additional ROs in addition to the first set of ROs. The one or more additional ROs may be available to some user equipments (UEs) such as network energy savings (NES)-capable UEs and unavailable to other UEs such as non-NES-capable UEs. A UE to which the one or more additional ROs are available may use a different power control parameter for transmission of a physical random access channel in an RO of the original set of ROs after activation of the one or more additional ROs as compared to prior to activation of the one or more additional ROs. The different power control parameter may be a different maximum transmission power level or an offset to the transmission power.

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 first scheduling information for a first set of random access channel occasions;
receive a first control message that indicates a first power control parameter associated with the first set of random access channel occasions;
receive second scheduling information for a set of additional random access channel occasions;
receive a second control message that indicates an availability of an additional random access channel occasion of the set of additional random access channel occasions;
and
transmit a physical random access channel via a random access channel occasion of the first set of random access channel occasions in accordance with a second power control parameter based at least in part on the availability of the additional random access channel occasion, wherein the second power control parameter is associated with a different transmission power than the first power control parameter.
