摘要: Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing schemes consider punctured bits as unknown bits, and set the log likelihood ratio (LLR) for those bits to zero; while other puncturing schemes consider punctured bits as known bits, and set the LLR for those bits to infinity. Each of these puncturing schemes has been observed to provide benefits over the other under different circumstances, especially corresponding to different coding rates or different signal to noise ratio (SNR). According to aspects of the present disclosure, both puncturing schemes are compared, and the puncturing scheme resulting in the better performance is utilized for transmission.

摘要: Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

摘要: Certain aspects of the present disclosure provide techniques for channel state information acquisition in wireless communication systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a user equipment (UE) generally includes receiving a first beamformed channel state information reference signal (CSI-RS), determining, based on the first beamformed CSI-RS and the beacon reference signal, information regarding an adjustment, preferred by the UE, of a beam-former to be used for a forthcoming second beamformed CSI-RS, transmitting a beamformer adjustment indicator (BAI), periodically, semi-persistently, or aperiodically, that indicates the preferred adjustment, and reporting channel state information feedback (CSF), based on the first beamformed CSI-RS.

摘要: Design of precoding and feedback for user equipment (UE)-specific reference signals (UE-RS)-based open-loop and semi-open-loop multiple input, multiple output (MIMO) systems is discussed. Aspects of the present disclosure provide for sub-resource block (RB) random precoding that allows for greater diversity gain in a lower bandwidth. In addition, the recoding may be performed using resource element (RE)-level layer shifting that provides for a number of precoders to be assigned to a number of layers for every such continuous subcarrier. As such, two codewords may experience the same effective channel quality with channel quality indicators (CQI) being averaged across all of the layers.

摘要: The present disclosure, for example, generally relates to wireless communication systems, and more particularly to techniques for flexible duplexing in such systems. For example, a technique for flexible duplexing provides a reference configuration that determines characteristics for paired frequency division duplexing (FDD) bands when the uplink band is temporarily reconfigured for time division duplexing (TDD) use. A user equipment (UE) may use the reference configuration to determine hybrid automatic repeat request (HARQ) timing, schedule uplink transmissions, manage a soft buffer, and determine signaling formats. In an aspect, the UE may receive a reconfiguration message indicating a change for an FDD uplink band to a temporary TDD band. The UE may then determine a reference configuration for a pair of FDD bands including an FDD downlink band and the temporary TDD band, the reference configuration indicating a pattern of sub-frames associated with the pair of FDD bands.

摘要: 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.

摘要: 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.

摘要: In a TD-SCDMA user equipment (UE) with multiple receive chains, receive diversity may be implemented where multiple receive chains may simultaneously activate to receive downlink signals. Receive diversity may be enabled when single chain reception provides undesired results and when receive diversity will not impact power consumption too much. A state machine controls receive diversity operation based on operating conditions such as control channel activity, successful control channel decoding, signal-to-interference ratio, and other factors.
