Abstract: An apparatus of a wireless network access point (AP) and related method execute a sounding sequence with a station (STA) to obtain channel information. During the sounding sequence, the apparatus decodes an uplink null data packet (UL NDP) transmitted from the STA to the AP and encodes a downlink null data packet (DL NDP) for transmission by the AP to the STA. During a measurement report sequence, the apparatus determines STA transmission time and angle data based on the obtained channel information, and encodes the STA transmission time and angle data in a location measurement report (LMR) transmission to the STA. The AP sends the STA(s) its LMR, and the STA(s) send the AP their LMRs in response to a LMR trigger frame.

Abstract: Disclosed are methods, systems, devices, and computer readable storage medium to manage a received signal strength of sounding frames at a receiving device. If the received signal strengths vary, an automatic gain control parameter may be more highly influenced by those frames having higher received signal strength. A trigger frame indicates a transmission power of the trigger frame, and a target received signal strength at an access point transmitting the trigger frame. Receiving stations may determine a transmit power for a sounding frame based on the trigger frame. For example, a path loss between the access point and receiving station may be determined based on the transmit power and the received power of the trigger frame. A transmit power for the sounding frame may then be determined, in some aspects, by adding the path loss and the target RSSI value.

Abstract: A wireless access point (AP) requests a response from a group of wireless station (STAs) and a STA within the group of STAs provides a response to the request in a resource block (RB). The AP may encode, for transmission, a null data packet (NDP) feedback report poll variant trigger frame including a request and specifying a range of association identifiers (AIDs) associated with STAs scheduled to respond. The STA may decode the trigger frame and determine whether the AID of the STA is within the range of AIDs associated with STAs scheduled to respond to the request. When within the range of scheduled AIDs, the STA may encode an NDP feedback in an RB represented by a resource unit (RU) together with a spatial stream (SS). The AP may receive the NDP feedback report response from the STA and determine the response to the request.

Abstract: Embodiments of a station (STA), an access point (AP) and methods of communication are generally described herein. The AP may select a back-off counter value to be used for contention-based access to a channel in unlicensed spectrum. The AP may monitor the channel to determine whether the channel is idle during a back-off period. A duration of the back-off period may be based on the back-off counter value. The AP may, if it is determined that the channel is idle during the back-οff period, transmit a co-existence reference signal (CRS) during a slot of an active collision resolution (ACR) period to indicate: that the AP determined that the channel was idle during the back-off period, and an intention of the AP to obtain exclusive access to the channel during a data transmission (DT) period after the ACR period.

Abstract: A wireless communication system may use a dual mode sounding reference signal (SRS) scheme to improve both beam tracking and uplink channel measurements. An eNB may transmit control signals directing user equipment (UE) to transmit either a first type of SRS or a second type of SRS.

The UE also may use the first SRS for beamforming calculations, use the second SRS for uplink channel measurements, and transmit data over a physical uplink shared channel (PUSCH) based on the calculations and measurements.
