摘要： Techniques are described for permitting uplink feedback for downlink transmission over downlink-only RF carriers to occur using uplink control channels belonging to another fully-configured RF carrier herein known as a primary carrier. Uplink feedback channels can be allocated for the downlink-only RF carriers in the uplink control regions of a fully-configured RF carrier immediately following the uplink control channels for the primary carrier are allocated. The uplink feedback channels for downlink-only RF carriers can be allocated based on global or local index number of each downlink-only RF carrier in sequential order based on ascending or descending sorting of the index numbers.

摘要： Techniques are disclosed involving preamble sequences. For instance, an apparatus includes a module to provide a preamble sequence having multiple values, where each of the values corresponds to an orthogonal frequency division multiplexing (OFDM) subcarrier. These multiple values may include multiple blocks of values based on a differentially encoded and scrambled row of a Hadamard matrix. The apparatus may further include a modulation module to produce an OFDM modulated signal from the preamble sequence. Further, techniques for the detection of such preambles are disclosed.

摘要： When scanning for available channels, a wireless mobile device may reduce the number of channels it scans, and therefore reduce the amount of time spent in scanning, by using the information from some of the scanned channels to eliminate the need to scan some of the other channels. In some embodiments in which multiple smaller channels may be combined into larger channels, information gained from one of the smaller channels may show that another smaller channel is associated with it, and thereby eliminate the need to scan that other channel.

摘要： Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

摘要： This disclosure describes systems, methods, and devices related to delay indication. A device may identify a first frame received from a first station device, wherein the first frame comprises a first transition delay field, wherein the first transition delay field comprises a first transition delay value associated with a power state transition. The device may determine a wake up receiver (WUR) frame comprising an indication for waking up the main radio of the first station device. The device may cause to send the WUR frame to the first station device based on the first transition delay value.

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.
