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.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be included in a plurality of APs affiliated with a multi-link AP logical entity. As part of a multi-link AP logical entity, the plurality of APs may share a common medium access control (MAC) data service interface to an upper layer. The AP may exchange signaling with an STA as part of a multi-link setup process between the multi-link TP logical entity and a multi-link non-AP logical entity. The STA may be included in a plurality of STAs affiliated with the multi-link non-AP logical entity. The multi-link setup process may establish a link between each AP of the plurality of APs and a corresponding STA of the plurality of STAs.

摘要： Logic may generate a wake-up radio packet, wherein the wake-up radio packet comprises an on-off keying (OOK) signal, a sequence of a preamble of the wake-up radio packet to indicate a rate of transmission of one or more OOK orthogonal frequency-division multiplexing (OFDM) symbols of a medium access control (MAC) frame of the wake-up radio packet, wherein a duration of transmission of the preamble is 128 microseconds for a low data rate and a duration of transmission of the preamble is 64 microseconds for a low data rate. Logic may communicate the wake-up radio packet to a physical layer device to transmit OFDM symbols of an IEEE 802.11 preamble on a channel followed by OOK OFDM symbols of the wake-up radio packet on a sub-band of the channel. And logic may generate at least a second wake-up radio packet to transmit on a contiguous channel bandwidth with OOK OFDM symbols.

摘要： Embodiments for an access point (AP) and method for communication in a basic service set (BSS) of a management domain are generally described herein. The AP may be configured to maintain a list of BSSs that belong to the management domain and retrieve, for a station (STA) configured to perform spatial reuse over overlapping basic service set (OBSS) physical layer convergence protocol (PLCP) protocol data units (OBSS PPDUs) belonging to OBSSs from the management domain, at least one parameter for a spatial reuse rule that proportions overlapping basic service set packet detection levels (OBSS_PD) and transmit power (TxPower) levels for the STA. In an embodiment, the AP may retrieve, for a STA configured to perform spatial reuse over OBSS PPDUs not belonging to OBSSs from the management domain, default parameters for a spatial reuse rule that proportions OBSS_PD and TxPower levels for the STA and encode, for transmission to the STA belonging to the OBSSs from the management domain, an indication of the at least one parameters, and encode, for transmission to the STA not belonging to OBSSs from the management domain, an indication of the default parameters.

摘要： Computing readable media, apparatuses, and methods for random access with carrier sensing are disclosed. An apparatus is disclosed including processing circuitry configured to: decode a trigger frame, the trigger frame to indicate resource units (RUs) for random access and to indicate if a carrier sense (CS) is to be performed. The processing circuitry may be further configured to: decrement a value of an orthogonal frequency division multiple-access (OFDMA) backoff (OBO) field based on a number of the RUs indicated for random access. The processing circuitry may be further configured to: when the value of the OBO field reaches a predetermined value, randomly select one of the RUs indicated for random access, and if the CS is to be performed, determine a virtual CS based on one or more network allocation vectors (NAVs) and perform a physical CS on the selected RU, and if the virtual CS and the physical CS both indicate that the selected RU is idle, configure the wireless device to transmit a physical (PHY) layer convergence procedure (PLCP) protocol data units (PPDU) on the selected RU in accordance with OFDMA.

摘要： Devices and methods of providing a NAN schedule update are generally described. NAN devices communicate data on a schedule of repeating time blocks in which transmission in different time blocks are on different channels. A public action frame indicates in a subfield that the frame is a schedule update frame. The schedule update frame provides attributes to have general schedule update for availability time, existing unicast service or existing multicast service. The schedule update frame also contains a schedule update control field that indicates in a subfield that the current time block is cancelled or extended or provides a general schedule update. The schedule update control field also indicates a reason for the schedule update.

摘要： A multicast publisher and method of establishing multicast scheduling are provided. The publisher determines a schedule for a multicast service that is selected from time slots of a schedule candidate. The schedule candidate is set by the publisher that initiates the multicast group. The multicast group is one-to-many or many-to-many. A response to a request for the service is transmitted to a subscriber and contains the multicast schedule. The response indicates whether the service is available for unicast transmission in addition to multicast. A schedule selection policy for other multicast publishers joining the multicast group specifies that the other multicast publishers are to follow the multicast schedule acquired when joining the multicast group, use the multicast schedule candidate to determine a multicast schedule, or are free to choose a multicast schedule.
