Abstract
A method, an apparatus, a base station, a user equipment, and a computer program product for wireless communication are provided. The base station may configure resource allocation for wakeup signaling based at least in part on one or more resource patterns corresponding to different user equipment groups and/or antenna port configurations. The user equipment may receive a wakeup signal based at least in part on the resource allocation, detect the wakeup signal based at least in part on a preamble of the wakeup signal, and receive a subsequent communication based at least in part on the wakeup signal. Numerous other aspects are provided.
Claims40
A method of wireless communication performed by a base station, comprising:
- transmitting a wakeup signal using a resource selected from one of:
- one or more first resources of a first resource pattern corresponding to transmission of the wakeup signal using a first antenna port, or
- one or more second resources of a second resource pattern corresponding to transmission of the wakeup signal using a second antenna port;
- and
- transmitting a communication to a user equipment (UE) based at least in part on the wakeup signal.
A method of wireless communication performed by a user equipment (UE), comprising:
- scanning a particular resource of a resource pattern to identify a wakeup signal associated with the UE;
- receiving the wakeup signal from a base station on the particular resource of the resource pattern, wherein the resource pattern corresponds to an antenna port via which the wakeup signal was transmitted;
- and
- identifying the wakeup signal as associated with the UE based at least in part on a cell identifier associated with the UE, wherein at least a portion of the cell identifier is indicated by the wakeup signal.
A base station for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- transmit a wakeup signal using a resource selected from one of:
- one or more first resources of a first resource pattern corresponding to transmission of the wakeup signal using a first antenna port, or
- one or more second resources of a second resource pattern corresponding to transmission of the wakeup signal using a second antenna port;
- and
- transmit a communication to a user equipment (UE) based at least in part on the wakeup signal.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- scan a particular resource of a resource pattern to identify a wakeup signal associated with the UE;
- receive the wakeup signal from a base station on the particular resource of the resource pattern, wherein the resource pattern corresponds to an antenna port via which the wakeup signal was transmitted;
- and
- identify the wakeup signal as associated with the UE based at least in part on a cell identifier associated with the UE, wherein at least a portion of the cell identifier is indicated by the wakeup signal.
