Abstract
A communication apparatus of the present disclosure comprises a first receiver which, in operation, receives a downlink data frame from a base station; a decoder which, in operation, decodes data included in the received downlink data frame; a signal generator which, when the decoded data indicates that there is no buffered traffic for the communication apparatus, generates an uplink frame that includes acknowledgement information and a wake-up radio (WUR) mode request indicating a request to transit to the WUR mode from a primary connectivity radio (PCR) mode; and a transmitter which, in operation, transmits the uplink frame to the base station.
Claims5
An integrated circuit for a station, the integrated circuit comprising:
- at least one input, which, in operation, receives an input;
- and
- control circuitry, which is coupled to the at least one input and, which, in operation, performs:
- controlling an operation of the station in a wake-up radio (WUR) mode to alternate between a WUR awake state and a WUR doze state;
- receiving a WUR wake-up frame when the station is in the WUR awake state, and not receiving the WUR wake-up frame when the station is in the WUR doze state;
- in response to receiving the WUR wake-up frame, finishing the operation of the station in the WUR mode and controlling a power save (PS) operation of the station;
- without receiving the WUR wake-up frame, finishing the operation of the station in the WUR mode by transmitting a management frame indicating a finish of the operation;
- generating a PS poll frame which elicits a transmission of buffered data from an access point (AP) in the PS operation after the WUR wake-up frame is received;
- and
- eliciting the transmission of buffered data from the AP in the PS operation.
