摘要： Some embodiments include an apparatus, method, and computer program product for access point (AP) power save enhancements. AP power save enhancements reduce power consumption for APs including multi-link device (MLD) APs, mobile APs and mobile AP stations. Some embodiments include an uplink (UL) multi-user (MU)-Request to Send (RTS) power save feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power mode to receive data using a bandwidth greater than 20 MHz. Some embodiments include a Target Wake Time (TWT) UL MU-RTS AP power enhancement feature that allows an AP to operate in the LPR during a TWT service period (SP). Some embodiments allow mobile devices (e.g., a smart phone) to operate in as an AP (e.g., a mobile AP, a mobile AP station) and reduce power consumption.

摘要： Some embodiments include an apparatus, method, and computer program product for access point (AP)-assisted AP transition. Using AP-assisted AP transitions, when the STA is associated with a first access point (AP) and is transitioning to a second AP, a station (STA) can transmit to the second AP a control signal including a first indication for sequence number (SN) maintenance. The STA can receive from the second AP responsive to the first indication for SN maintenance, a first downlink (DL) transmission including a next SN. The next SN can be a continuation of an SN sequence utilized by the first AP for one or more previous DL transmissions.

摘要： This disclosure relates to methods for multi-access point association in a wireless local area network. Multiple access point wireless devices may establish a multi-access point system. Other access point wireless devices may subsequently join the multi-access point system. Non-access point wireless devices may form an association with the multi-access point system, which may include links with multiple different access point wireless devices in the multi-access point system.

摘要： Disclosed are methods, systems, and computer-readable medium to perform operations including detecting a reception opportunity of a physical layer protocol data unit (PPDU) scheduled to be transmitted by a transmitter, where the PPDU includes a preamble and one or more media access control (MAC) PDUs (MPDUs); decoding the preamble of the PPDU; detecting that reception of the one or more MPDUs has failed; and in response to the detecting, preparing a Negative Acknowledgment (NACK) message for transmission to the transmitter.

摘要： This disclosure relates to methods for transmission preemption in a wireless local area network. An access point wireless device may establish a wireless association with another wireless device. A first data transmission may be initiated. The transmitting wireless device may determine to preempt the first data transmission prior to its completion. The transmitting wireless device may transmit signaling indicating that the first data transmission is preempted.

摘要： Multiuser (MU) Multi-TID (multi-traffic-identifier) transmission may be enabled in a resource unit (RU). To transmit an urgent payload as soon as possible, the urgent payload may be injected/included into the ongoing MU physical protocol data unit (MU PPDU), if possible. This may be accomplished by indicating to the latency-sensitive wireless station (STA) the ID of a companion (or buddy) station that has an assigned resource unit (RU) on which the STA may expect to receive the urgent payload, also referred to as the “overloaded RU.” Alternatively, an extra user field in the preamble of the MU PPDU may be used to indicate to the STA its station ID as well as the location of the overloaded RU. A receiver operating on an A-MPDU may select the RU it receives, and may identify (or determine) a wrong transmission based on the transmitter address.

摘要： A second electronic device that receives a frame is described. This second electronic device includes: an antenna node communicatively coupled to an antenna; and a second interface circuit, communicatively coupled to the antenna node, that communicates with an electronic device. During operation the second interface circuit receives, associated with the electronic device, the frame that includes an indication that the electronic device uses a frame-based equipment (FBE) channel access technique and attributes of the FBE channel access technique. The attributes include: a duration of the FBE channel access technique, and a fixed frame period (FFP) for communication during the FBE channel access technique. Moreover, the frame is compatible with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

摘要： This disclosure relates to methods for managing uplink transmit opportunity bursting for wireless local area networking. A wireless device may initiate a transmit opportunity to perform an uplink transmission to an access point. The wireless device may receive an acknowledgement from the access point. The acknowledgement may include an indication that the wireless device can initiate a second transmit opportunity without wireless medium contention. The wireless device may initiate the second transmit opportunity without wireless medium contention based at least in part on the indication received from the access point.
