    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.

    Abstract: A transmission apparatus of the present disclosure comprises a transmission signal generator which, in operation, generates a transmission signal that includes a legacy preamble, a non-legacy preamble and a data field, wherein the non-legacy preamble comprises a first signal field and a second signal field, the second signal field comprising a first channel field for a first subband channel and, when the transmission signal occupies more than one subband channel, the second signal field further comprising a second channel field for a second subband channel different from the first subband channel, each of the first channel field and the second channel field comprising a user-specific field that includes a plurality of user fields, each user field carrying per-user allocation information for corresponding one of one or more terminal stations, and wherein the plurality of user fields are split equitably between the first channel field and the second channel field when a full bandwidth that covers the first subband channel and the second subband channel is allocated for multi-user (MU) MIMO transmission; and a transmitter which, in operation, transmits the generated transmission signal.

    Abstract: A transmission apparatus of the present disclosure comprises a transmitter that transmits a Trigger Frame for allocating resources for Uplink Multi User (UL MU) transmission, the Trigger Frame comprising a common information field that includes a type subfield indicating one of a plurality of trigger types, wherein the plurality of trigger types includes a first trigger type indicating a basic trigger used for soliciting any type of response frame from a recipient terminal station a second trigger type indicating a specific trigger used for soliciting a specific type of UL MU response frame from a plurality of terminal stations; and a receiver that receives the specific type of UL MU response frame from the plurality of terminal stations when the type subfield indicates the second trigger type.

    IPC: H04W52/02

    Abstract: A communication apparatus comprises primary connectivity radio (PCR) circuitry which, in operation, exchanges a wake up radio (WUR) mode setup frame with a communication partner apparatus in awake state; and wake up radio (WUR) circuitry which, in operation, receives a wake-up frame from the communication partner apparatus, wherein upon successful completion of the WUR mode setup frame exchange in mode other than WUR mode, the communication apparatus enters the WUR mode in which the WUR circuitry is in state to receive a WUR frame, and wherein upon receiving the wake-up frame by the WUR circuitry in the WUR mode, the PCR circuitry changes current state to the awake state.
