摘要： Apparatuses, computer readable media, and methods for restricting enhanced distributed coordination access (EDCA) in a high-efficiency wireless local-area network (HEW) are disclosed. The apparatus of a HEW station may include processing circuitry and transceiver circuitry. The processing circuitry and transceiver circuitry may be configured to configure the HEW station for operation in enhanced distributed coordinated access (EDCA) restricted mode, where in EDCA restricted mode the HEW station is configured to refrain from EDCA packet transmission. The processing circuitry and transceiver circuitry may be further configured to configure the HEW station for operation in non-EDCA restricted mode where in non-EDCA restricted mode the HEW station is configured to: increase a EDCA attempt failure counter when acknowledgement of an EDCA-transmitted packet is not received within a predetermined period of time, and enter EDCA restricted mode when the EDCA attempt failure counter equals a EDCA threshold.

摘要： Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for communication in a wireless network are generally described herein. In some embodiments, the HEW AP may transmit a resource allocation message to indicate an allocation of sub-channels to one or more HEW stations for uplink data transmissions. Information included in the resource allocation message may include various indicators related to full or partial allocation of the sub-channels and whether equal allocations are made for each of the HEW stations. A sub-channel mapping block may also be included to indicate how the sub-channels are assigned to the HEW stations. In some cases, the length of the sub-channel mapping block may vary based at least partly on the indicators included in the message.

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 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 first access node of a first network utilizes code sequences, assigned to different user devices, to distinguish at least acknowledgements received in parallel or sequentially from those user devices. The first access node determines from received signaling that a root sequence of the code sequences is in use by a second access node of a second network, then changes that root sequence of the code sequences assigned to the different user devices. In certain examples the access nodes are WLAN access points APs and the acknowledgements are received in response to a group probe/poll. In various embodiments the first AP monitors its neighbors' group probes/polls to learn the root sequences/basic service sets in use in those neighbor networks, or the AP's own stations monitor and send the information in neighbor reports. This latter option can be initiated by the stations themselves, or by the AP.

摘要： A method includes receiving indications of a wake-up interval assigned to a station and a corresponding group to which the station belongs, wherein all stations assigned to the group are assigned the wake-up interval. The method includes waking the station during the wake-up interval and determining, using at least the indication of the group, whether information received by the station during the wake-up interval corresponds to the group. Another method includes assigning stations to one of multiple groups based on wake-up intervals, in which stations assigned to a group all have a same wake-up interval and each group has a different wake-up interval, sending indications of a corresponding wake-up interval and a corresponding group to each of the stations, and during a interval corresponding to the wake-up interval for a selected group, transmitting the indication of the selected group and associated information meant for the group.
