Abstract

Methods, apparatuses, and computer readable media for MU-RTS and CTS are disclosed. An apparatus of a high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master station including processing circuitry configured to generate a packet to indicate a multi-user request-to-send (MU-RTS) and to indicate channels on which one or more HEW stations are to transmit a clear-to-send (CTS). The HEW master station further including a transceiver configured to transmit the packet to the one or more HEW stations, and receive clear-to-send responses to the packet on the one or more channels. An apparatus of a HEW station is also disclosed. The HEW station including circuitry configured to receive a packet that indicates a MU-RTS that indicates channels on which the HEW station is to transmit a CTS, and to determine whether to send the CTS.

Dependent claims

An apparatus of a high-efficiency (HE) station (STA), the apparatus comprising:

memory;
and processing circuitry coupled to the memory, the processing circuitry configured to:
decode a trigger frame (TF) from an access point, the TF comprising an uplink (UL) resource allocation for the HE STA to transmit a bandwidth query report (BQR) to the access point, wherein the TF comprises an indication that the TF is of type bandwidth query report poll (BQRP);
in response to the TF, determine whether each 20 MHz subchannel of a plurality of 20 MHz subchannels is busy, and set a corresponding bit of the BQR to indicate whether a corresponding 20 MHz subchannel is busy;
generate signaling to configure the HE STA to transmit the BQR to the access point in accordance with the UL resource allocation.
