Abstract: This disclosure provides methods, devices and systems for providing energy detection based resolution in radio access technologies. In one aspect, a wireless communication device may include a first energy detection threshold (EDT) to identify a transmission opportunity in an unlicensed frequency band. The wireless communication device may detect a second wireless communication device having a second EDT to identify the transmission opportunity, the second EDT being greater than the first EDT. The wireless communication device may, based on detection of the second wireless communication device having the second EDT, modify a transmission configuration of the first wireless communication device.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for increasing local area network (LAN) device privacy. One aspect provides a method for wireless communications at an access point (AP). The method generally includes: determining a mapping between a first distribution system (DS) medium access control (MAC) address and a second DS MAC address; obtaining, from a source access terminal, a frame having the second DS MAC address; and sending at least a portion of the frame to a target access terminal based on the mapping between the first MAC address and the second MAC address.

Abstract: This disclosure provides systems and methods for requesting wireless resources for peer-to-peer (P2P) communications. In some implementations, a wireless communication device transmits a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header carrying a request for the AP to allocate part of a transmission opportunity (TXOP) for P2P communications between the wireless communication device and a client device. The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QoS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.

Abstract: Certain aspects of the present disclosure provide techniques for handling direct link communications in multi-link systems. An example method generally includes transmitting, to a first wireless station via a direct link between the first wireless station and one or more second wireless stations affiliated with a multi-link device (MLD), a data frame comprising a transmitter address field set to an address of the MLD, which is one of a plurality of addresses associated with the MLD and the second wireless stations being affiliated with the MLD for multi-link operations. The method also includes communicating with the first wireless station via the direct link.

Abstract: In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

Abstract: This disclosure provides methods, devices and systems for communicating over multiple links, for example, indicating buffered units (BUs) per traffic identifier (TID) for transmission to multi-link devices (MLDs). One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method can be performed, for example, by a non-access point (non-AP) MLD. The non-AP MLD can receive an indication of an association identifier (AID) associated with the non-AP MLD, wherein the indication of the AID indicates whether an AP has BUs for the non-AP MLD, determine one or more links associated with one or more TIDs based on a mapping of a plurality of TIDs, including the one or more TIDs, to a plurality of links, including the one or more links, receive the BUs associated with the one or more TIDs from the AP on the determined links.

Abstract: This disclosure provides systems, methods, apparatus and wireless nodes as well as computer programs encoded on computer-readable mediums for providing synchronized start times of backoff windows in a given or particular physical area. In some implementations, a schedule of synchronized start times may be determined and an indication that the first schedule is active may be signaled. In some other implementations, signaling indicating a first schedule of synchronized start times is active may be detected and channel access may be performed according to the first schedule.

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. In some other implementations, for each of the frames, the wireless device may signal at least a portion of the unique sequence number using bit locations unassociated with a sequence number field of the frame header.
