摘要： This disclosure provides methods, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), an indication of a puncturing event. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the puncturing event. In certain aspects, the disclosure provides methods for transmitting and receiving, between the AP and one or more STAs, an indication of an operating band switch. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the operating band switch.

摘要： 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.

摘要： This disclosure provides methods, devices and systems for enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information.

摘要： 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.

摘要： This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

摘要： An access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field, one or more secondary change sequence fields, and a critical update flag subfield. The first change sequence field carries a value of the most-recent critical update for the first AP. The one or more secondary change sequence fields carry values of the most-recent critical updates for the one or more respective secondary APs. The critical update flag subfield carries an indication of a change in value of at least one of the secondary change sequence fields. The first AP transmits the frame over the first communication link of the AP MLD.

摘要： 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.

摘要： This disclosure provides methods, devices and systems for non-simultaneous transmit and receive (STR) station (STA) transmissions using multiple links. In one aspect, a medium synchronization delay timer associated with a second link of the non- STR STA can be initiated in response to completing transmission of the data on the first link to delay triggering of a clear channel assessment (CCA) associated with the second link. Data can be transmitted on the second link in response to expiration of the medium synchronization delay timer. In another aspect, an energy detect (ED) threshold level on a second link may be decreased from a first ED threshold level to a second ED threshold level after transmitting the data on the first link.

摘要： This disclosure provides systems, methods, and apparatus for wireless communications. In one aspect, an apparatus may obtain, for a first access point (AP), a first service set identifier (SSID) associated with single-link communications and obtain, for a second AP, a second SSID associated with multi-link communications. The apparatus may obtain, from a wireless communication device, a management frame include a multi-link operation information field that carries a first SSID and obtain a multi-link indication for the wireless communication device based, at least in part, on the first SSID, the multi-link indication indicating whether the wireless communication device includes AP capable of link aggregation, and selectively associate with the wireless communication device based on the multi-link indication.
