Abstract: Apparatuses, computer readable media, and methods for extending a long-training field are disclosed. An apparatus of a high-efficiency (HE) wireless local-area network (HEW) device is disclosed. The apparatus including transceiver circuitry and processing circuitry configure to determine if a HE long training field (HE-LTF) portion of a HE physical layer convergence procedure (PLCP) protocol data unit (HE-PPDU) is to be extended, and if the HE-LTF portion is to be extended, configure the HE-LTF portion to use a longer symbol duration, or one or more additional HE-LTFs. The transceiver circuitry and processing circuitry configure also to transmit the HE-PPDU in accordance with orthogonal frequency division multiple access (OFDMA). An apparatus of a HEW device includes circuitry configured to receive a HE-LTF portion of a HE-PPDU, determine if the HE-LTF portion of the HE-PPDU is extended, and if the HE-PPDU portion is extended, use the extended portion to improve channel estimates.

Abstract: 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.

Abstract: 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.

Abstract: One exemplary embodiment provides an efficient method and architecture that allows the transmission of at least two different data services with different quality of service (QOS) and source encoding for the IEEE 802.11.ax-HEW (and beyond, 802.11ax+) Wi-Fi systems/networks. An exemplary embodiment capitalizes on the behavior of spatial modulation (SM-OFDM) transmission techniques to allow, for example, using different channel encoding rates for each category/service of data.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) device and method for HEW communicating are generally described herein. In some embodiments, an HEW frame is configured with a reduced signal field. The HEW frame may include a HEW signal field (HEW SIG-A1) which may include a single bit to indicate whether the HEW frame is a single user (SU) HEW frame or a multi-user (MU) HEW frame. A legacy signal field (L-SIG) is not included in the HEW frame. Rate information may be included in one or more signal fields that follow the HEW SIG-A1 and length information may be included in either the HEW SIG-A1 or the one or more signal fields that follow the HEW SIG-A1. The HEW frame may improve overall system efficiency, particularly in high-density deployment situations.

Abstract: Embodiments of a HEW device and method for communicating in a high-efficiency Wi-Fi (HEW) network generally described herein. In some embodiments, an HEW frame may be configured to include an HEW long-training field (HEW-LTF) and the HEW-LTF may include an HEW long-training sequence (HEW-LTS) that is orthogonal on a block-by-block basis to a legacy LTS (L-LTS). The HEW frame may be transmitted as part of a data unit for reception by one or more HEW devices. In some embodiments, an HEW device and method for packet classification is provided. A packet classification may be determined from the HEW-LTF by determining which of a plurality of HEW-LTSs are included in the HEW-LTF.
