Abstract: Techniques for supporting distributed MIMO are described. For multi-user distributed MIMO, a cell directs its transmit power toward a UE while reducing interference to UE(s) in neighbor cell(s). For single-user distributed MIMO, multiple cells concurrently send transmissions to a UE. In an aspect, a UE sends channel estimates for serving and non-serving cells to support multi-user distributed MIMO. Each cell may use the channel estimates to select UEs for data transmission and determine precoding vectors to use for data transmission to the selected UEs. In another aspect, a UE sends CQI information for serving and non-serving cells to support single-user distributed MIMO. Each cell may use the CQI information to select UEs for data transmission and determine modulation and coding schemes to use for the selected UEs. In yet another aspect, a UE determines CQI information for a serving cell by taking into account interference nulling by non-serving cells.

Abstract: In accordance with a method for distributed beamforming based on carrier to caused interference, a base station may receive channel state information from users. The base station may select a codeword from a codebook. The codeword may be selected so as to maximize a utility function that is based on a signal-to-caused-interference-plus-noise ratio. The base station may use the codeword for beamforming.

Abstract: Methods and corresponding apparatuses for wireless communication are disclosed. The method for wireless communication includes dividing a two-dimensional antenna array to a plurality of sub-arrays, mapping the two-dimensional antenna array into a one-dimensional vertical channel state information reference signal (CSI-RS) port array for receiving elevation CSI feedback and a one-dimensional horizontal CSI-RS port array for receiving azimuth CSI feedback, and transmitting one or more elevation CSI-RS from the one-dimensional vertical CSI-RS port array and one or more azimuth CSI-RS from the one-dimensional horizontal CSI-RS port array. Methods and corresponding apparatuses for CSI feedback mechanism are also disclosed.

Abstract: Methods, systems, and apparatuses are described for flexible transmissions on one or more frequency division duplexing resources. In some aspects, a subset of resources originally allocated for transmissions in a frequency division duplex (FDD) mode of operation associated with a first base station is identified for reallocation, and the identified subset of resources is reallocated to transmissions in a time division duplex (TDD) mode of operation, for example, associated with a second base station.

Abstract: Methods, systems, and devices are described for providing periodic CSI reports and/or aperiodic CSI reports to provide CSI for both anchor and non-anchor TDD subframes in eIMTA. Periodic CSI reports may be provided based on a reference configuration, and aperiodic CSI reports may be provided based on a time of reception of a CSI request and a reference configuration. A UE may determine to report anchor or non-anchor CSI through explicit or implicit signaling. Aperiodic CSI may be used for transmission of anchor subframe CSI reports and periodic CSI may be used for transmission of non-anchor subframe CSI reports, or aperiodic CSI may be used for transmission of non-anchor subframe CSI reports and periodic CSI may be used for transmission of anchor subframe CSI reports. A determination of the reference subframe for aperiodic CSI estimation may be based on a time of receipt of an aperiodic CSI request.

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.
