Abstract: Certain aspects of the present disclosure support demodulation reference signal (DMRS) enhancement for higher order multi-user multiple-input multiple-output (MU-MIMO) communications. An example method generally includes determining a plurality of ports of a multi-dimensional array of transmit antennas and a number of spatial multiplexed layers for transmission to a plurality of user equipments (UEs), configuring a demodulation reference signal (DMRS) pattern by multiplexing the layers or the ports in the DMRS pattern, using an orthogonal cover code (OCC) and one or more code division multiplexing (CDM) groups, and transmitting DMRS symbols based on the configured DMRS pattern using the multiplexed layers and the ports.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a location of a reference subframe based on an A-CSI report uplink subframe, an A-CSI request downlink subframe, a reference delay, and a report delay. In an aspect, the reference delay is a first delay value before the A-CSI report uplink subframe, and the report delay is a second delay value between the A-CSI request downlink subframe and the A-CSI report uplink subframe. The apparatus determines a type of the reference subframe based on the location of the reference subframe and a subframe configuration, the type of the reference subframe being a flexible subframe or a fixed subframe. The apparatus measures at least one of a channel or interference based on the reference subframe and the type of the reference subframe. The apparatus sends, at the A-CSI report uplink subframe, an A-CSI report based on the at least one of the channel or the interference.

Abstract: Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for measuring and mitigating interference. Such interference may include base station to base station (eNB to eNB) interference and/or UE to UE interference. A base station may determine a first subframe configuration for the base station and a second subframe configuration for one or more other base stations, wherein the first and second subframe configurations have different ratios of uplink to downlink portions. The base station may measure interference caused by the one or more other base stations based on reference signals transmitted in downlink portions of the second subframe configuration.
