摘要： Logic to “loosely” manage synch frame transmissions in a synch network via the devices synced to the network that implement the logic. Logic may distributedly adjust the frequency of attempting synch frame transmissions without estimating the size of the neighborhood. Logic in devices of a synch network to let each device maintain a Transmission Window (TW). Logic to determine the frequency of attempting synch frame transmissions based upon the TW. Logic to increase TW if the device detects a synch frame transmission. Logic to decrease TW if the device successfully transmits a synch frame. Logic to balance power consumption and discovery timing by adjusting the decrease in TW responsive to a synch transmission in relation to the increase in TW responsive to detection of a synch transmitted by another device.

摘要： An extremely high throughput (EHT) device configured for operation in an EHT network may negotiate a block acknowledge (BA) agreement with another EHT device including negotiate a maximum size of a receive reordering buffer to be up to one-third of sequence number (SN) space The SN space may have a predetermined maximum number of 4096 entries and may be signaled by twelve bits. When a larger reordering buffer is needed, the EHT STA may be configured to negotiate a larger reordering buffer size and additional SN space and may be configured to add additional signalling bits to signal the additional SN space.

摘要： An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

摘要： This disclosure describes systems, methods, and devices related to high throughput (HT) control information. A device may determine a frame comprising HT control information. The device may determine to extend a size of the HT control information. The device may cause to generate a management or data frame for sending to a first station device of one or more station devices, the management or data frame comprising extended high throughput (HT) control information, define a new control identification (ID) associated with the extended HT control information, and cause to send the management or data frame to the first station device.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. An AP may be configurable to operate as a master AP of a multi-AP group comprising the master AP and one or more satellite APs. The master AP may select, from the multi-AP group, a set of APs that is to communicate with a STA in accordance with joint processing. The master AP may allocate one or more spatial streams to each of the APs of the set of APs for a joint transmission of a null data packet (NDP) to the STA for channel sounding. The master AP may transmit an NDP announcement (NDPA) that indicates that the APs of the set of APs are to perform the joint transmission of the NDP.

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.
