Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a device-to-device (D2D) link receives from a base station an indication of an acceptable level of interference that the base station can tolerate on an uplink resource. The uplink resource is allocated to a user equipment (UE) for a wide area network (WAN) transmission. The acceptable level of interference is a level of interference that the base station can tolerate on the uplink resource while the base station receives the WAN transmission from the UE. The apparatus determines a level of interference to the UE's transmission at the base station and performs a D2D communication on the uplink resource allocated to the second UE for the WAN transmission if the determined level of interference is less than the acceptable level.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include transmitting a first synchronization signal in a set of beam directions during a first symbol period of a synchronization subframe and transmitting a second synchronization signal in another set of beam directions during a second symbol period of the synchronization subframe. The second set of beam directions may be spatially interleaved with the first set of beam directions. Additionally, the method may include monitoring a first and second set of beam directions during a first and second symbol period of a random access subframe, respectively. Additionally, the method may include receiving, from a base station, first and second synchronization signals in a synchronization subframe, decoding the first synchronization signal, and transmitting an access request based at least in part on the decoded first synchronization signal.

Abstract: Disclosed are techniques for identifying beams of interest for position estimation. In an aspect, a first node receives, from a second node, a plurality of beams, determines a time of arrival of each beam, identifies one or more beams of interest for determining a position estimate based on the times of arrival, and sends, to the second node, a report identifying each of the one or more beams of interest. A second node transmits, to a first node, a plurality of beams, receives a report identifying one or more beams of interest for determining a position estimate of the first node, wherein the one or more beams of interest are a subset of the plurality of beams, and transmits, in response to receiving the report, at least one beam carrying position reference signals for the second node in a same direction as the one or more beams of interest.

Abstract: Methods, systems, and devices for wireless communications are described for antenna selection and reporting for multiple-input multiple-output (MIMO) communications. One or more grouping parameters may be provided to a wireless node, which may indicate a subset of antennas that are to be used for MIMO communications, may indicate one or more target nodes for MIMO communications, or combinations thereof. The wireless node may measure one or more channel parameters based on the grouping parameters and determine one or more antenna subsets or target nodes that meet MIMO communication parameters (e.g., an antenna group or target node that will support a certain rank of MIMO communications). The wireless node may report an indication of the identified antenna subsets or target nodes to a control entity for scheduling of MIMO communications.
