Abstract: Embodiments describe mechanisms for an Access Point (AP) to aggregate multiple devices (e.g., stations (STA)) across frequency during a single time period. STAs will be considered for frequency aggregation only if they have a measured SNR at the AP below a threshold. Methods are described that select STAs for aggregation based on associated SNR and other criteria and then assign frequency slots to the selected STAs. Selection for aggregation and assignment to frequency slots can also be balanced across time, so that different STAs are selected for aggregation over time. Mechanisms are also described that increase the opportunities for frequency aggregation.
Abstract translation: 实施例描述了在单个时间段期间跨越频率聚合多个设备（例如，站（STA））的接入点（AP）的机制。 只有在AP处的测量SNR低于阈值时，才考虑STA的频率聚合。 描述了基于相关联的SNR和其他标准选择用于聚合的STA的方法，然后将频率隙分配给所选择的STA。 对频段进行聚合和分配的选择也可以跨时间进行平衡，以便随着时间的推移选择不同的STA进行聚合。 还描述了增加频率聚合的机会的机制。

Abstract: For example, an apparatus may include a segment parser to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits, the PPDU to be transmitted in an OFDM transmission over an aggregated bandwidth comprising a first channel in a first frequency band and a second channel in a second frequency band; a first baseband processing block to encode and modulate the first plurality of data bits according to a first OFDM MCS for transmission over the first channel in the first frequency band; and a second baseband block to encode and modulate the second plurality of data bits according to a second OFDM MCS for transmission over the second channel in the second frequency band.

Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.

Abstract: Embodiments of an access point (AP) may comprise memory and processing circuitry coupled to the memory, and transceiver circuitry coupled to the processing circuitry. The processing circuitry of the AP may be configured to encode a trigger frame to allocate a center 26 tone RU of an 80 MHz channel for an HE-trigger-based PPDU, the center 26 tone RU having an adjacent upper 20 MHz subchannel and an adjacent lower 20 MHz subchannel. In an embodiment, the center 26 tone RU is for a station (STA) and wherein the trigger frame indicates to the STA to transmit a pre-HE-STF preamble on one of the adjacent upper 20 MHz subchannel, the adjacent lower 20 MHz subchannel, or both the adjacent upper and lower 20 MHz subchannels, and configure the wireless device to transmit the trigger frame to the station.

Abstract: Described are methods and devices for increasing the efficiency of Wi-Fi networks by increased spatial reuse, which refers to sharing the same wireless spectral resources over different spatial regions. A described technique for doing this is for a Wi-Fi device to increase the threshold of the clear channel assessment (CCA) so as to ignore and regard as interference the transmissions from other devices. The sensing range of the Wi-Fi device then decreases, and the spatial resource can be reused by different Wi-Fi devices in different spatial locations.

Abstract: Some embodiments relate to methods, computer readable media, and apparatus for resolving acknowledgements between associated and unassociated stations. An apparatus is disclosed including processing circuitry configured to decode responses to a random-access trigger frame, wherein one of the responses is a response from an unassociated station. The processing circuitry may be further configured to: encode an acknowledgement to acknowledge receipt of the response from the unassociated station, where the acknowledgement comprises an indication that the acknowledgement is for the unassociated station, and where the acknowledgement further comprises a media access control (MAC) address of the unassociated station in a field of the acknowledgement other than a field in a MAC header portion of the acknowledgement. The processing circuitry may configure the HE access point to transmit the acknowledgement.

Abstract: Embodiments of fast steering timing and resource allocation are generally described herein. In some embodiments, a non-access point station (STA) decodes a fast steering timing signaling element (STSE) at a Narrow Band Control sub-Channel (NB-C-CH) and from an allocator device, the STSE indicating at least fast steering timing information, an identified Narrow Band Service sub-Channel (NB-S-CH), resource allocation information for the identified NB-S-CH, and connectivity information for the identified NB-S-CH, the identified NB-S-CH being selected from a plurality of NB-S-CHs. The STA exchanges packets in the NB-S-CH according to the resource allocation information and the connectivity information and based on the fast steering timing information. The STA encodes or decodes data associated with the exchanged packets.

Abstract: Methods and apparatus are described by which a wireless station transmits information to an access point in response to a short feedback request. The response to the short feedback request is transmitted as either energy or lack thereof in one or more long training fields transmitted in a preamble of a physical layer packet. Short feedback trigger frames for requesting the short feedback are also described.

Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.
