    Abstract: Aspects of the present disclosure describe receiving, from an access point, an indication of at least one of a beamforming method for beamforming a RS or a normalization method for normalizing power for beamforming the RS. A channel covariance matrix corresponding to interference over a plurality of antenna ports can be generated, as well as a RS beamforming matrix based at least in part on at least one of modifying the channel covariance matrix or on the normalization method. The RS can be generated based on the RS beamforming matrix and the beamforming method. The RS can be transmitted to the access point based on the RS beamforming matrix.

    Abstract: Certain aspects of the present disclosure provide techniques for reference signal monitoring and transmission for remote interference management. In some cases, an aggressor base station decides to monitor for reference signals (RSs) transmitted from at least one victim BS, for example, regardless of an amount of interference from at least one remote BS detected by the first base station and participating in a remote interference mitigation (RIM) process based on the monitored RS. In some cases, a first BS transmits reference signals (RSs) as part of a remote interference mitigation (RIM) process, in response to a determination that it is an aggressor BS whose downlink transmissions possibly interfere with reception of uplink transmissions by at least one remote BS, a victim BS whose reception of uplink transmissions are possibly interfered with by downlink transmissions from the at least one remote BS, or both an aggressor BS and a victim BS.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a configuration message, wherein the configuration message in part configures the UE to communicate coordinated transmissions with a plurality of transmission reception points using a coordinated transmission mode. The method further includes, receiving one or more physical downlink shared channel transmissions from a plurality of transmission reception points in accordance with the coordinated transmission mode. The method further includes, selecting a HARQ-ACK feedback mode based in part on the coordinated transmission mode. The method further includes, transmitting HARQ-ACK feedback to at least one of the plurality of transmission reception points using the selected HARQ-ACK feedback mode.

    Abstract: Disclosed are techniques for transmitting and processing reference signals for positioning estimation over a multipath multiple-input multiple-output (MIMO) channel. In aspects, a first node configures first and second reference signal resource sets for transmission of first and second sets of reference signals, wherein the first and second reference signal resource sets occur on first and second subbands of, and/or during first and second time intervals on, the MIMO channel, wherein each reference signal resource in the first and second reference signal resource sets utilize at least first and second MIMO precoders, and transmits, to a second node over the MIMO channel, the first and second sets of reference signals, wherein the first node transmits the first and second sets of reference signals to assist the second node to perform a positioning measurement based on joint processing of the first and second sets of reference signals.

    Abstract: Systems and methods for determining round trip time (RTT) includes a second node, which receives a first signal from a first node at a first time, determines a timing advance based on a first estimated channel response for the first signal, and transmits at a second time, a second signal to the first node, wherein the second time occurs after the first time by an amount of a pre-specified delay for RTT estimation minus the timing advance. The first node transmits the first signal to the second node at an initial time, receives the second signal from the second node, and determines a timing statistic from a second estimated channel response for the second signal, the timing statistic estimated at a third time. The first node determines the RTT as the third time minus the initial time minus the pre-specified delay for RTT estimation.
