Claim of US Patent No. 10,219,286

1. An apparatus for an enhanced directional multi-gigabit (EDMG) station (STA), the apparatus comprising: memory; and processing circuitry coupled to the memory, the EDMG STA configurable to operate on multiples of a 2.16 GHz channel, the processing circuitry to, when the STA is configured to operate as a source STA (SSTA):encode a grant frame for transmission to indicate a transmission to a destination EDMG station (DSTA), the DSTA being a peer EDMG STA, the grant frame to indicate intent to transmit data by the SSTA to the DSTA,
wherein the grant frame is encoded for transmission, the grant frame to include:
a dynamic allocation information field;
control signaling that includes a bitmap indicating a channel to be used for transmission of the data, wherein the channel is indicated by the bitmap, the bitmap being configurable to indicate one or more multiples of a 2.16 GHz channel, and configurable to indicate a 2.16 GHz bandwidth channel and a 4.32 GHz bandwidth channel, the bitmap occurring after a start of the dynamic allocation information field;
wherein the channels comprise a primary channel for transmission of the grant frame and the non-primary channel for transmission of the data, the primary channel being a 2.16 GHz channel, the non-primary channel being one or more multiples of a 2.16 GHz channel;
wherein the grant frame is further encoded to include a source association identifier (AID) for the SSTA, and a destination AID for the DSTA; and
wherein the processing circuitry is further configured to:
process a grant acknowledgement frame received from the DSTA, the grant acknowledgment frame acknowledging receipt of the grant frame by the DSTA; and
encode the data for transmission to the DSTA on the non-primary channel when the bitmap of the grant frame indicates that the data is to be transmitted on the non-primary channel, and
encode the data for transmission to the DSTA on the primary channel when the bitmap of the grant frame indicates that the data is to be transmitted on the primary channel.
