Abstract
Apparatus, methods, and computer program products for backscatter communication (BC) are included. An example method may include transmitting an indication of a backscattering radio (BR) capability to a network entity. The example method may also include receiving a first message from the network entity, the first message indicating that the UE is to remain on a main radio (MR) state or transition to a BR state.
Claims29
An apparatus for communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- receive, from a network entity, an announcement indicating a support of backscatter communication (BC) for the UE;
- transmit, based on the announcement, an indication of a backscattering radio (BR) capability to the network entity;
- receive, after transmission of the indication of the BR capability to the network entity, a BC configuration in a BC bandwidth part (BWP) dedicated for the BC communication;
- transmit, after reception of the BC configuration, a request message to the network entity, wherein the request message indicates a request to transition to a BR state from a main radio (MR) state;
- and
- receive a first message from the network entity, the first message indicating that the UE is to remain on the MR state or transition to the BR state.
