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： For communication utilizing polar codes, a hybrid automatic repeat request (HARQ) algorithm is provided that takes advantage of the benefits of chase combining HARQ (HARQ-CC) and incremental redundancy HARQ (HARQ-IR), by selecting one or the other in accordance with a code rate of the first transmission. In some examples, the HARQ algorithm utilizes HARQ-IR when the code rate in the first transmission is greater than a code rate threshold, and utilizes HARQ-CC when the code rate in the first transmission is less than the code rate threshold.

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： Aspects of the present disclosure relate to techniques for wireless communications and more specifically for performing a random access channel (RACH) procedure. According to certain aspects a method for retransmitting a RACH MSG3 message is provided. The method generally includes participating in a random access channel (RACH) procedure with a user equipment (UE), dynamically changing an uplink/downlink subframe configuration from a first uplink/downlink subframe configuration to a second uplink/downlink subframe configuration, during the RACH procedure, detecting a failure to successfully decode a MSG3 message from the UE, and taking action to prevent the UE from re-transmitting the MSG3 message in a subframe that is designated as a downlink subframe after dynamically changing the subframe configuration.

摘要： The present disclosure relates to systems and methods for a two-dimensional discrete Fourier transform (2D-DFT) based codebook for elevation beamforming. The method comprises: determining a two-dimensional discrete Fourier transform (2D-DFT) based codebook for elevation beamforming; generating the 2D-DFT based codebook; selecting a best codebook index from the generated 2D-DFT based codebook; providing the selected codebook index in a CSI report; and transmitting the CSI report to a base station. The use of a 2D-DFT based codebook for elevation beamforming may provide flexibility for joint optimization of elevation and azimuth. The 2D-DFT based codebook may also reduce CSI feedback overhead.
