AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in supporting efficient mobility transitions due to longer latency, higher overhead, and disruption times during serving cell changes, particularly in next-generation networks like 5G, which require more complex access requirements and flexibility.

Method used

Implementing Layer 1/Layer 2 (L1/L2) mobility techniques through transmission configuration indication (TCI) states, including methods for configuring and activating TCI state pools/sets using RRC and MAC CE signaling to reduce latency and disruption during cell changes.

Benefits of technology

Enables low-latency, low-overhead serving cell changes by optimizing TCI state indication procedures, reducing disruption times and enhancing mobility performance in wireless networks.

Abstract

Techniques for enabling Layer 1 / Layer 2 (L1 / L2) mobility for wireless devices, such as user equipment (UE), are disclosed. Methods, systems, and apparatuses for wireless communication are described. One example method includes receiving, by the wireless device, from a network device, a first signal indicating one or more Transmission Configuration Indication (TCI) states or sets of TCI states, and conducting communication between the wireless device and the network device according to the indicated TCI states.
