Abstract
A transmission apparatus of the present disclosure comprises a signal generator which, in operation, generates a transmission signal that comprises a data field containing a WUR (Wake Up Radio) Mode Setup frame; wherein a field of a WUR Mode element included in the WUR Mode Setup frame contains the information on Group IDs (Identifiers) assigned by an AP (Access Point) to the station comprising the transmission apparatus; and a transmitter which, in operation, transmits the generated transmission signal.
Claims17
A station comprising:
- a receiver, which, in operation, receives a signal that includes a data field, the data field including a Wake Up Radio (WUR) Mode Setup frame, wherein a field of a WUR Mode element included in the WUR Mode Setup frame includes information on group identifiers (IDs) assigned by an Access Point (AP) to the station;
- and
- circuitry, which, in operation, decodes the received signal,
- wherein the field includes a subfield including a group ID bitmap whose size is equal to a number of group IDs that the AP is configured to provide, and in response to bit Y of the group ID bitmap being set to 1 (Y=0, 1, . . . , L−1, and L is the size of the group ID bitmap), the group ID assigned by the AP to the station is equal to a smallest group ID, that the AP is configured to provide, plus Y.
A communication method implemented by a station, the communication method comprising:
- receiving a signal that includes a data field, the data field including a Wake Up Radio (WUR) Mode Setup frame, wherein a field of a WUR Mode element included in the WUR Mode Setup frame includes information on group identifiers (IDs) assigned by an Access Point (AP) to the station;
- and
- decoding the received signal,
- wherein the field includes a subfield including a group ID bitmap whose size is equal to a number of group IDs that the AP is configured to provide, and in response to bit Y of the group ID bitmap being set to 1 (Y=0, 1, . . . , L−1, and L is the size of the group ID bitmap), the group ID assigned by the AP to the station is equal to a smallest group ID, that the AP is configured to provide, plus Y.
An Access Point (AP) comprising:
- circuitry, which, in operation, generates a signal that includes a data field, the data field including a Wake Up Radio (WUR) Mode Setup frame, wherein a field of a WUR Mode element included in the WUR Mode Setup frame includes information on group identifiers (IDs) assigned by the AP to a group of stations;
- and
- a transmitter, which, in operation, transmits the generated signal,
- wherein the field includes a subfield including a group ID bitmap whose size is equal to a number of group IDs that the AP is configured to provide, and in response to bit Y of the group ID bitmap being set to 1 (Y=0, 1, . . . , L−1, and L is the size of the group ID bitmap), the group ID assigned by the AP to the group of stations is equal to a smallest group ID, that the AP is configured to provide, plus Y.
