CN-122029864-A - Random access for sensing

Abstract

Aspects of the present disclosure relate to UEs for association and mapping between beam sets, processors for wireless communications, network entities, methods, and computer-readable media. The UE sends a random access preamble associated with the sensing trigger to the network entity. The UE also receives a sensing signal configuration from a network entity. The UE also receives a sensing signal from the network entity based on the sensing signal configuration. In this way, the UE in the idle/inactive state may request a sensing signal from the network during random access without transitioning to the connected state.

Background A wireless communication system may include one or more network communication devices, such as base stations, which may also be referred to as enodebs (enbs), next generation nodebs (gnbs), or other suitable terminology. Each network communication device, such as a base station, may support wireless communication for one or more user communication devices, which may also be referred to as User Equipment (UE) or other suitable terminology. A wireless communication system may support wireless communication with one or more user communication devices by utilizing resources (e.g., time resources (e.g., symbols, slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) of the wireless communication system.
