Abstract: Embodiments are provided for enabling a coordinated beamforming (CB) mechanism in WLAN scenarios. In an embodiment, an AP sends a Feedback Request (FBR) frame to each one of the STAs in the OBSSs. The OBSSs comprise the STAs and a plurality of APs including the AP. The AP then receives a feedback frame from each STA of the STAs that participate in the CB transmission. The feedback frame includes channel state information (CSI) of the STA. The CSI enables the sending AP of performing CB on downlink. In an embodiment, the AP receives an initiate CB frame from a second AP initiating a CB transmission, and then sends an ACK frame to the second AP before sending the FBR frame to each one of the STAs. The AP starts the CB transmission with each one of the other APs that participate in the CB transmission.

Abstract: An OFDMA subframe carrying different data fields in different time segments may include a separate short training field (STF), and a separate set of long training fields (LTFs), for each of the data fields to accommodate time-reuse scheduling. Communicating a separate STF for each data field may allow receivers to re-adjust automatic gain control (AGC) when the data fields carry different numbers of space-time-streams. Likewise, communicating separate sets of LTFs for each data field may allow different beamforming parameters to be applied to different data fields.

Abstract: Embodiments are provided herein for improving carrier aggregation for wireless networks. A plurality of bandwidth channels are assigned to a basic service set (BSS) for transmissions. Specifically, the bandwidth channels are divided into multiple channel segments corresponding to multiple primary or alternate primary channels. A channel segment possibly further includes one or more additional secondary channels. The locations of the primary or alternate primary channels that correspond to the channel segments of the BSS are then broadcasted in the network. When a station or AP receives this BSS information, it searches for an available primary or alternate primary channel of the BSS to begin transmission. Upon detecting an available primary channel or alternate primary channel that is not used for another transmission, the station or AP transmits data on the channel segment corresponding to the detected primary or alternate primary channel.
