摘要： This disclosure provides methods, devices and systems for transmitting and receiving physical protocol data units (PPDUs) over multiple links. In some aspects, a wireless communication device may determine that first random back off (RBO) for a first channel of a first link has counted down to zero. A wireless communication device may determine, when the first RBO has counted down to zero, that a second RBO for a second channel of a second link has a count down remaining. A wireless communication device may optionally transmit a medium reservation message on the first link reserving a transmission opportunity (TXOP). A wireless communication device may determine whether to wait for the second RBO before transmitting on the first link. A wireless communication device may transmit at least a first PPDU on the first link during the TXOP.

摘要： The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

摘要： Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.

摘要： Various aspects of the disclosure relate to communication using a data unit that includes a payload with synchronization information. In some aspects, a first apparatus may transmit a data unit that includes at least one synchronization symbol in the payload. A second apparatus that receives the data unit may thereby recover synchronization information from the data unit even if interference at the second apparatus prevents the second apparatus from recovering synchronization information in a preamble of the data unit. In some aspects, the second apparatus may determine, based on information in the at least one synchronization symbol, whether and/or when to conduct a spatial reuse transmission. In some aspects, the second apparatus may determine, based on information in the at least one synchronization symbol, an amount of time to defer transmission.

摘要： Certain aspects of the present disclosure relate to communicating acknowledgements to multiple un-associated stations simultaneously. Certain aspects of the present disclosure provide a method for wireless communications by an access point (AP). The method includes receiving a first message from a first station (STA) that is not associated with the AP. The method further includes receiving a second message from a second STA that is not associated with the AP. The method further includes generating an aggregated acknowledgement message. The aggregated acknowledgement message includes a first acknowledgement (ACK) for the first message and a second ACK for the second message. The method further includes broadcasting the aggregated acknowledgement message for reception by the first STA and the second STA.

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： Aspects of the present disclosure provide techniques for high efficiency (HE) basic service set (BSS) operations. In an implementation, a wireless station (STA) can identify a set including one or more modulation coding scheme (MCS) and number of spatial streams (NSS) tuples for HE communications in wireless local area networks (WLANs). The STA can determine whether the set is supported by a BSS and also determine that the STA is to attempt to join the BSS in response to a determination that the set is supported by the BSS. In another implementation, the STA can set a channel width capability for high throughout (HT) communications and very high throughput (VHT) communications in WLANs to be the same as a channel width capability for HE communications in WLANs, and can transmit information that indicates that the STA has the same channel width capability for HT, VHT, and HE communications in WLANs.
