摘要： Logic may enable reverse direction communication with improved power efficiency. Logic may transmit a packet to a Responder during a transmission opportunity with an indication of a reverse direction grant. Logic may receive a response to the packet indicative of a lack of data packets to transmit by the Responder. Logic may enter a defer transmission mode in which transmissions are deferred during the transmission opportunity for greater than a point coordination function interframe space (PIFS) within the transmission opportunity. Logic may grant data transmission rights of the transmission opportunity during the defer transmission mode to the Responder. Logic may grant a contention-based data transmission rights of the transmission opportunity during the defer transmission mode. Logic may grant data transmission rights of the transmission opportunity during the defer transmission mode to the Granter.

摘要： This disclosure describes systems, methods, and devices related to enhanced feedback for secure mode wireless communications. A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.

摘要： A method and apparatus for reducing power consumed by mobile wireless units, such as personal communications systems or wireless PBX telephones, by reducing the frequency with which various circuits within the units are fully energized. During on-going voice communications between a base station and a wireless unit, the wireless unit reduces the frequency of its references to a control channel and may eliminate such references altogether. In addition, while idle, the wireless units may not attempt to reference the control channel during all occurrences of the control channel, reducing both power consumption and the possibility of collisions with other wireless units in attempting to access the control channel.

摘要： An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.
