Abstract: This disclosure provides methods, devices and systems for enhanced bandwidth negotiation. Some implementations more specifically relate to request-to-transmit (RTS) and clear-to-send (CTS) frame designs that support bandwidth negotiations over a range of bandwidths achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, a bandwidth negotiation frame (such as a CTS or RTS frame) may be configurable to support bandwidths greater than 160 MHz. In some aspects, the bandwidth negotiation frame may conform to a legacy control frame format. More specifically, one or more bits of a service field associated with the legacy control frame format may be repurposed to carry enhanced bandwidth information. In some aspects, a recipient of a bandwidth negotiation frame may interpret one or more bits of the service field to carry enhanced bandwidth information when the frame is transmitted by a non-legacy transmitting device.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for identifying frames or packets of data that were received in error (such as incorrectly decoded or not received at all) by a receiving device for purposes of retransmission. In one aspect, a wireless device may form a number of frames for wireless transmission. Each of the frames may include a frame header and may be associated with a unique sequence number. In some implementations, for each of the frames, the wireless device may embed at least a portion of the unique sequence number into a portion of a control field or a delimiter field of the frame header.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support a 20 MHz station (STA) parked on a secondary channel. Without the described techniques, mechanisms to support secondary channel operation may be unable to receive management frames or broadcast traffic from an access point (AP), which may cause the STA to lose synchronization with the AP, miss a channel change or other critical announcement from the AP, etc. Considerations for providing such information to STAs parked on a secondary channel are discussed. In some examples, an AP may restrict resource unit allocation to the secondary channel on which the STA is parked. In some cases, a trigger-based random access mechanism may utilize aspects of the present disclosure to limit access to certain resource units to STAs on a given secondary channel.

Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.

Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.
