Abstract: Systems and techniques for random access to a wireless network are described herein. Components of a wireless station may obtain a back-off value. The components may also decode random access resource units from a frame transmitted to the wireless station from an access point of the wireless network. The components may decrement the back-off for each decoded random access frame. The wireless station may select this frame from a sequence of frames when the back-off reaches zero while decoding the random access resource units of this frame. The wireless station then selects the random access resource unit with a more favorable transmission metric than another random access resource unit of the frame and uses the selected random access resource unit to communicate with the access point.

Abstract: Devices and techniques for dynamic patterned resource allocation in a wireless network are described herein. Components of a wireless station may obtain a set of dynamic patterns, where members of the set define a sequence of resource units for the wireless network. The components may receive a data unit from an access point of the wireless network, the data unit including a group designation for the wireless station. The components may select one of the set of dynamic patterns based on the received group designation and communicate on the wireless network using resource units specified by the selected dynamic pattern.

Abstract: Methods, apparatuses, and computer readable media are disclosed to signal a packet configuration. A HEW device to signal a packet configuration may include circuitry. The circuitry may be configured to generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields and include in the L-SIG the packet configuration of the HE packet to signal to a second HEW device. The circuitry may configure a length field of the L-SIG to be a one or two modulo of three (MOD 3) to indicate the HE packet. The length field of the L-SIG may indicate that the HE packet includes a portion that has a one-quarter size subcarrier. The circuitry may set the length field of the L-SIG to be 1 mod 3 to indicate a first type of HE packet and to be 2 mod 3 to indicate a second type of HE packet.

Abstract: Embodiments of an access point and method for high-efficiency WLAN (HEW) communication are generally described herein. In some embodiments, the access point may be configured to operate as a master station and may configure an HEW frame to include a legacy signal field (L-SIG), an HEW signal field (HEW SIG-A) following the L-SIG, and one or more HEW fields following the HEW SIG-A. The L-SIG may be configured for transmission using a legacy number of data subcarriers, a legacy number of pilot subcarriers and a number of additional reference subcarriers modulated with a known reference sequence. At least one symbol of the HEW SIG-A and the one or more HEW fields following the HEW SIG-A of the HEW frame may be configured for transmission using additional data subcarriers. The additional data subcarriers may correspond to the additional reference subcarriers of the L-SIG.

Abstract: Embodiments of a transmission signaling structure for HEW are defined to carry packet information to configure OFDMA receivers for demodulation of a specific portion of the packet and/or to configure receivers for transmission using specific OFDMA and MU-MIMO resources. In some embodiments, the specific portion of the packet comprises one or more minimum bandwidth units of one or more 20 MHz channels. Each 20 MHz bandwidth structure may comprise several minimum bandwidth units to allow each 20 MHz channel to have a have smaller granularity than 20 MHz.

Abstract: Embodiments of a system and methods for distinguishing high-efficiency Wi-Fi (HEW) packets from legacy packets are generally described herein. In some embodiments, an access point may select a value for the length field of a legacy signal field (L-SIG) that is non-divisible by three for communicating with HEW stations and may select a value for the length field that is divisible by three for communicating with legacy stations. In some embodiments, the access point may select a phase rotation for application to the BPSK modulation of at least one of the first and second symbols of a subsequent signal field to distinguish a high-throughput (HT) PPDU, a very-high throughput (VHT) PPDU and an HEW PPDU.
