The HEW master station further including a transceiver configured to transmit the packet to the one or more HEW stations, and receive clear-to-send responses to the packet on the one or more channels. An apparatus of a HEW station is also disclosed. The HEW station including circuitry configured to receive a packet that indicates a MU-RTS that indicates channels on which the HEW station is to transmit a CTS, and to determine whether to send the CTS.

    Abstract: This disclosure describes systems, methods, and devices related to using enhanced high efficiency (HE) frames. A device may determine a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field and a user information field. The device may determine a data portion of the HE frame, wherein the data portion includes one or more resource units (RUs) with a size equal to a number of tones. The device may determine a first resource allocation subfield and a second resource allocation subfield of the common information field based at least in part on the number of tones. The device may cause to send the HE frame.

    Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises one or more baseband processors to decode one or more channel state information reference signals (CSI-RS) received from an evolved Node B (eNB) using open loop full-dimension multiple input, multiple output (FD-MIMO), and to generate feedback to the eNB responsive to the one or more CSI-RS signals, and a memory to store a Class A codebook from which the feedback is generated, wherein the feedback includes an i1 codebook index of the Class A codebook and a channel quality indicator (CQI) determined based at least in part on i2 codebook index cycling across one or more physical resource blocks (PRBs). In some embodiments, Class B feedback using a Class B codebook by be utilized.

    Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field. An apparatus is disclosed comprising processing circuitry configured to: encode a first high efficiency (HE) physical-layer convergence procedure (PLCP) protocol data unit (PPDU) comprising a transmission opportunity (TXOP) duration field in a first physical-layer portion of the first HE PPDU. The processing circuitry may be further configured to set the TXOP duration field value to indicate a largest duration value representable by the TXOP duration field that is equal to or less than a duration value indicated by the first MAC duration field, if the first HE PPDU is to include a first media access control (MAC) duration field in a first MAC-layer portion of the first HE PPDU.

    Abstract: This disclosure describes methods, apparatus, and systems related to an OFDMA uplink resource allocation framework. An access point may determine a first trigger frame including one or more resource block identifications (RBIDs) associated with one or more resource units on a communication channel. The access point may assign at least one of the one or more RBIDs to at least one device of one or more devices. The access point may cause to send the first trigger frame to the least one device The access point may identify a resource request frame including at least in part a resource request indication associated with the at least one of the one or more RBIDs. The access point may assign one of the one or more resource units based at least in part on the resource request indication.

    Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for virtual carrier sensing with two network allocation vectors (NAV). An apparatus of a wireless device is disclosed. The apparatus comprising processing circuitry configured to: determine a duration of a frame, determine whether the frame is an intra basic service set (Intra-BSS) frame, an inter-BSS frame, or an unclassified frame. The processing circuitry may be further configured to set an intra-BSS network allocation vector (NAV) to the duration of the frame, if the frame is determined to be the intra-BSS frame, and if a receiver address is decoded from the frame and the receiver address is not an address of the wireless device. The processing circuitry may be further configured to set a regular NAV to the duration of the frame, if the frame is determined to be the inter BSS frame or the unclassified frame.
