摘要： Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for random access contention in a wireless network are generally described herein. In some embodiments, the HEW station may receive a beacon frame that indicates a number of trigger frames (TFs) included in a beacon interval. The beacon frame may be received from an HEW access point (AP) in channel resources that include multiple sub-channels. The HEW station may receive a random access TF that indicates a random access portion of the sub-channels that are allocated for random access contention during an uplink transmission period. The HEW station may select a candidate sub-channel from the channel resources. When the candidate sub-channel is included in the random access portion, the HEW station may transmit an association request (AR) frame on the candidate sub-channel during the uplink transmission period.

摘要： A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

摘要： Logic to manage synch frame transmissions in a synch network via helper stations (STAs) synched to the network. Logic may coordinate actions of helper STAs via a transmission window (TW) provided by a master clock STA. Logic may distribute synch frame transmissions within a TW via synch logic in the helper STAs. Logic in helper STAs of a synch network may determine discovery periods in which to transmit synch frames between synch frame transmissions by the master clock STA. Logic in helper STAs to determine a discovery period in which to transmit synch frames to share workload with the master clock STA and to extend the coverage area of the synch network. Logic of the master clock STA may establish a fixed TW based upon the number of helper STAs and a time constraint for discovering the synch network. Or logic of the master clock STA may establish a dynamic TW in which the master clock STA can adjust the TW based upon a number of synch frame transmissions during a TW.

摘要： Examples are disclosed for multi-level service discovery. In some examples, a first level of information indicating a service type for a service provided by a first wireless device may be transmitted by the first wireless device to another wireless device. The first level may enable the other wireless device to determine whether the indicated service type at least partially matches a service interest. A second level may then be transmitted by the first wireless device that includes a service identification to enable the other wireless device to determine whether the service substantially matches a service interest for the other wireless device. A third level may then be transmitted from the first wireless device that includes service content information. The third level may be transmitted responsive to the other wireless device requesting the service content information. Other examples are described and claimed.

摘要： For example, a wireless communication station (STA) may be configured to set a Message Integrity Code (MIC) in a MIC field to protect contents of a control frame according to a Galois Message Authentication Code with 256-bit cipher-key (GMAC-256) protection mechanism. For example, the MIC may be based on a Packet Number (PN). For example, a size of the MIC field may be less than 16 bytes. For example, the STA may be configured to set a PN field based on the PN. For example, a size of the PN field may be less than 6 bytes. For example, the STA may be configured to transmit the control frame including the MIC field and the PN field.
