    Abstract: A method of wireless communication includes determining how to handle a collision between the first sounding reference signal (SRS) and a second SRS when the second SRS may the same type as the first SRS and when both the first SRS and the second SRS may be transmitted in a same cell.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for performing coordinated multipoint (CoMP) channel state information (CSI) feedback under multiple channel and interference assumptions. One method generally includes receiving signaling indicating at least one or more interference measurement resources (IMRs) from a network and a configuration with one or more non-zero power reference signal (NZP-RS) resources in which one or more base stations transmit a RS, performing separate interference measurements at least on a per-IMR basis in one or more subframes by forming a baseline interference estimate based on the IMR and forming separate interference estimates based on adding interference from selected NZP-RS resources to the baseline interference estimate, and transmitting one or more CSI feedback reports that correspond to the interference measurements.

    Abstract: A method for wireless communication includes allocating overlapping sets of resources to different UEs. The resources may be for channel state information (CSI) measurement and received power measurements. The overlapping resources include a first set of resources, allocated to a first UE, for the CSI measurements and a second set of resources, allocated to a second UE, for the received power measurements. The method also includes receiving a CSI measurement report and a received power measurement report. The reports are based on the first set of resources and the second set or resources, respectively.
