摘要： Wireless devices, methods, and computer readable media are disclosed. A high-efficiency wireless local-area network (HEW) master station is disclosed. The HEW master station may include circuitry. The circuitry may be configured to generate one or more resource allocations of a bandwidth for one or more HEW stations. Each resource allocation for a first portion of the bandwidth may be a multiple of a basic resource allocation or the entire first portion of the bandwidth. There may be only one resource allocation for a second portion of the bandwidth that is at least as large as the first portion of the bandwidth. In some embodiments, each resource allocation for the second portion of the bandwidth may be a multiple of the basic resource allocation or the entire second portion of the bandwidth.

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： 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 station may perform random access contention with other HEW stations for uplink resources for data transmission to the HEW AP. The HEW station may determine transmission activity during a first portion of a channel sensing period, and may select a sub-channel on which transmission activity is not determined. The HEW station may transmit an announcement signal on the selected sub-channel during a second portion of the channel sensing period. The announcement signal transmission may indicate, to other contending HEW stations, an intention by the HEW station to transmit on the same selected sub-channel during a subsequent access period.

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 channel resources for uplink transmissions by one or more HEW stations. The channel resources may include multiple channels, each of which may include multiple sub-channels and an extra portion of channel resources. The resource allocation message may include multiple sub-channel allocation blocks to indicate an allocation for a particular HEW station. A length of the sub-channel allocation blocks may be based on various factors, such as a number of channels included in the channel resources and a sub-carrier bandwidth.

摘要： Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.

摘要： Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

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： Computing readable media, apparatuses, and methods for signaling for uplink sounding are disclosed. An apparatus is disclosed comprising processing circuitry. The processing circuitry may be configured to: decode a trigger frame comprising a resource unit (RU) allocation, and a spatial stream (SS) allocation for the first wireless device to transmit an uplink (UL) sounding signal, where the trigger frame include an indication that the trigger frame is for the UL sounding signal. The processing circuitry may be further configured to: determine a path loss based on the indication of the transmit power and a received power of the trigger frame at the first wireless device. The processing circuitry may be configured to: determine a transmit power for the UL sounding signal based on the path loss, and transmit the UL sounding signal in accordance with the RU allocation, the SS allocation, and the transmit power.
