Abstract: Methods, apparatuses and systems for using at least one sub-channel of a physical channel for uplink communication, the physical channel including a set of resources within first and second channel boundaries such that the physical channel includes a plurality of sub-channels, each sub-channel comprising a subset of the resources of the physical channel and having at least one sub-channel boundary which is not coincident with the first or the second channel boundaries, are provided. One representative apparatus includes a Station (STA) including: a processor, and a transmit/receive unit configured to: transmit, via an uplink, control information including a sub-channel SIG field indicating an identity of the STA, receive a trigger frame indicating one or more sub-channels available form among a plurality of sub-channels, determine which of the one or more sub-channels to acquire, and transmit data, via the uplink, using the one or more acquired sub-channels.

Abstract: Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported are determined based on the request for the aperiodic report. When a CQI/PMI/RI report and a HARQ ACK/NACK report coincide in a subframe, the HARQ ACK/NACK report is transmitted on PUCCH, and the CQI/PMI/RI report is transmitted on PUSCH.

Abstract: Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.

Abstract: Systems, methods, and instrumentalities are provided to implement a method of communicating a feedback in a wireless local area network (WLAN). A WLAN device may receive a data frame with a hybrid automatic repeat request (HARQ) data indicator in a frame header. The WLAN device may send an acknowledgement frame when the data frame is correctly received and decoded. The WLAN device may send a negative acknowledgement frame when the data frame is not correctly received and decoded.
