US 2026/0304305 A1 · METHODS, ARCHITECTURES, APPARATUSES AND SYSTEMS FOR RADIO AND NON-RADIO MEASUREMENT BASED CONTROL OF LAYER 1/LAYER 2 (L1/L2) MOBILITY

Abstract

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for wireless transmit/receive unit (WTRU) controlled layer 1/layer 2 triggered mobility (LTM). For example, the WTRU may receive information indicating a set of layer 1/layer 2 triggered mobility (LTM) configurations. The set of LTM configurations may be associated with and/or may include a set of events for triggering LTM switching to a set of candidate cells (and/or beams). The WTRU may perform a first set of non-radio measurements to determine a zone. A subset of the LTM configurations may be activated based on the determined zone. The WTRU may perform an LTM switch to one of the candidate cells based on one of the activated LTM configurations. The activated LTM configuration used for the LTM switch may be associated with an event that is triggered (e.g., jointly) using a second set of radio and non-radio measurements.

Dependent claims

A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:

receiving deployment and/or coverage zone information;
receiving configuration information indicating a L1/L2 Triggered Mobility (LTM) configuration associated with an intra-distributed unit (intra-DU) switch or an inter-DU switch, wherein the LTM configuration is associated with a joint triggering event based on (i) one or more radio measurement quantities and (ii) one or more non-radio measurement quantities;
performing one or more radio measurements and one or more non-radio measurements;
performing one of the intra-DU switch or the inter-DU switch which is associated with the LTM configuration based on the joint triggering event being satisfied using (i) the one or more radio measurement quantities obtained from the radio measurements and (ii) the one or more non-radio measurement quantities obtained from the non-radio measurements and the deployment and/or coverage zone information;
and
after performing the one of the intra-DU switch or the inter-DU switch, sending an uplink indication of the one of the intra-DU switch or the inter-DU switch.
