US 2026/0304235 A1 · TAG FOR C-LTM IN SPLIT NODE ARCHITECTURE

Abstract

Apparatus, methods, and computer program products for wireless communication are provided. An example method may include transmitting, to a candidate network node associated with a user equipment (UE), a preparation request that indicates a set of candidate cells associated with the UE. The example method may further include receiving, from the candidate network node associated with the UE, a preparation response that includes a set of configurations associated with the set of candidate cells associated with the UE. The example method may further include transmitting, to the UE, a RRC message that indicates a mapping between a set of timing advance groups (TAGs) to the set of candidate cells.

Dependent claims

An apparatus for wireless communication at a distributed unit (DU), comprising:

at least one memory;
and
at least one processor coupled to the at least one memory, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
receive, from a central unit (CU), a preparation request that indicates a set of candidate cells associated with a user equipment (UE);
and
transmit, to the CU, a preparation response that indicates a mapping between a set of timing advance groups (TAGs) to the set of candidate cells.
