摘要： Methods, apparatuses, computer readable media for setting spatial reuse field for uplink trigger-based PPDU are disclosed. An apparatus of a wireless device can include processing circuitry configured to decode a high efficiency (HE) physical-layer convergence procedure (PLCP) protocol data unit (PPDU) comprising a high-throughput (HT) control field in a media access control (MAC) portion of the HE PPDU. The processing circuitry is further configured to determine whether the HT control field of the HE PPDU contains uplink (UL) multi-user (MU) response scheduling information soliciting a response. in response to determining the HT control field contains the UL MU response scheduling information, the processing circuitry can encode, for transmission, the response PPDU to include a spatial reuse (SR) field set to a default entry.

摘要： An apparatus for a station (STA) is generally described herein. The STA includes a low-power WUR (LP-WUR), a local timing synchronization function (TSF) timer, and processing circuitry. The processing circuitry can decode a signal received from an access point (AP) at the LP-WUR, the signal including a TSF value, the TSF value including a subset of octets of a TSF timer associated with the AP. The STA can synchronize the local TSF timer of the STA with the TSF timer associated with the AP by adjusting a local TSF timer based on a count of a number of octets included in the subset of octets. The LP-WUR can wake up a wireless local area network (WLAN) radio of the STA at a wake-up time based on the local TSF timer. Other methods, apparatuses and systems are also described.

摘要： An access-point station (AP) configured for communicating multi-user (MU) physical layer protocol data units (PPDUs) (MU-PPDUs) with plurality of non-AP stations (STAs) using dynamic channel switching may acquire a transmission opportunity (TXOP) on a channel comprising a primary channel and one or more non-primary channels. The AP may encode a channel switching indication frame that may request that at least some of the STAs temporarily switch from operating on the primary channel to operating on one of the non-primary channels. The AP may decode a response frame from each of the STAs that are indicated to switch. Each response frame may be received on the non-primary channel that an indicated STA is requested to switch to. For a downlink (DL) transmission, the AP may encode a DL MU-PPDU comprised of a plurality of PPDUs of different physical layer (PHY) types including at least a first PPDU for transmission on the primary channel to a first STA that had not been instructed to switch to a non-primary channel, and at least a second PPDU for transmission on one of the non-primary channels to a second STA that had been instructed to switch to one of the non-primary channels.

摘要： Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.
