Abstract: Aspects of the present disclosure describe configuring a number of antennas in an antenna array to use in communicating in a wireless network. The number of antennas of the antenna array, less than all available antennas for transmission or reception in the antenna array, can be determined such to achieve a radio frequency (RF) power that results in a certain effective data rate for communicating in the wireless network. The number of antennas can be indicated, over a backhaul, to one or more other access points of the wireless network to coordinate using of the number of antennas at a determined time. One or more devices in the wireless network can be communicated with using the number of antennas.

Abstract: Aspects of the present disclosure are directed to device-to-device (D2D) and, more particularly, vehicle-to-vehicle (V2V) communication in which an efficient ranging protocol allows efficient ranging-assisted vehicle positioning. A vehicle transmits a first slot ID in a first control period, to indicate a first time slot for transmitting a first ranging signal in a ranging cycle including a plurality of time slots. The vehicle transmits the first ranging signal in the first time slot in the ranging cycle. From a second vehicle, the first vehicle receives a second ranging signal in a second time slot that is different from the first time slot in the ranging cycle. The first vehicle determines a first time-of-arrival (ToA) of the second ranging signal when received by the first vehicle, and transmits the first ToA in a second control period.

Abstract: The choice of a transmit (Tx)-Receive (Rx) beam pair out of many available beam pairs between a base station and a millimeter wave (mmW)-capable UE is directly related to the performance of transmission between the base station and the UE. A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) capable of (mmW) communication are disclosed to determine a new serving Tx-Rx beam pair based on priorities of the plurality of Tx-Rx beam pairs. The UE may select a Transmit (Tx)-Receive (Rx) beam pair from a plurality of Tx-Rx beam pairs available at the UE for measurement, based in part on a priority of the Tx-Rx beam pair, and update the priority of the selected Tx-Rx beam pair based in part on a combination of static information and dynamic information of the selected Tx-Rx beam pair.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: Methods and apparatuses are provided which may be used in a base station and/or user equipment (UE) to help determine whether device-to-device (D2D) communications in a shared radio frequency spectrum may be employed between UEs. For example, a base station may send a request to a UE indicating that the UE monitor a wireless signal transmission from another UE, and subsequently receive a report based on a resulting D2D channel measurement. The base station may determine whether the monitoring UE and the monitored UE are D2D communication candidates based, at least in part on the received report.

Abstract: Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity. The scheduling entity may then jointly select uplink and downlink beams based on both the received downlink beam measurement report and uplink beam measurements.
