Scheduled clear to send (CTS) for multiple user, multiple access, and/or MIMO wireless communications

摘要

Scheduled clear to send (CTS) for multiple user, multiple access, and/or MIMO wireless communications. Before sending transmissions, a request to send (RTS)/clear to send (CTS) exchange takes place between a transmitting wireless communication device and multiple receiving wireless communication devices may take place therein. The transmitting wireless communication device (e.g., an AP) may generate and transmit a multi-user request to send (mRTS) frame to a number of receiving wireless communication devices (e.g., STAs). The mRTS frame can include information and instructions therein to direct the manner by which all or a subset of the receiving wireless communication devices are to provide CTS responses back to the transmitting wireless communication device. The mRTS frame may be an OFDMA frame, a MU-MIMO frame, or a combination thereof. The CTS responses may be received in accordance with any one or combination of OFDM signaling, OFDMA signaling, and MU-MIMO signaling.

1. A wireless communication device, comprising:
a baseband processing module; and memory coupled to the baseband processing module to store operational instructions that, when executed, cause the baseband processing module to:
receive a multi-user request to send (mRTS) frame that is operable to effectuate multiple clear to send (CTS) response transmissions to a subset of a plurality of wireless communication devices including the wireless communication device, the mRTS frame including a plurality of CTS response instructions with operational parameters to govern a manner by which the multiple CTS response transmissions are to be transmitted, each of the plurality of CTS response instructions directed to a corresponding one the subset of the plurality of the wireless communication devices, the operational parameters including scheduling information for a CTS response order based at least in part on a receive capability of each of the subset of the plurality of wireless communication devices; andtransmit, in response to a respective CTS response instruction of the mRTS frame, a clear to send (CTS) response.
