摘要： Systems and methodologies are described herein that facilitate Hybrid Automatic Repeat Request (H-ARQ) scheduling and coordination in a wireless communication system. As described herein, a network node capable of cooperation with other nodes for communication to respective users can coordinate a cooperation strategy across nodes based on a H-ARQ protocol to be utilized for a given user. In the case of a synchronous H-ARQ protocol, communication can be scheduled as described herein such that initial transmissions to a user are conducted cooperatively and re-transmissions are conducted without inter-node cooperation. In the case of a H-ARQ protocol utilizing persistent assignments, transmission intervals can be calculated and utilized based on application latency requirements, backhaul link latency, or other factors. In the case of an asynchronous H-ARQ protocol, repeat transmissions can be coordinated in a similar manner to initial transmissions or conducted without inter-node cooperation based on latency sensitivity of an associated application.

摘要： Techniques for generalized pilot interference cancellation in a communications receiver. In an exemplary embodiment, a residual pilot is cancelled from a post-traffic cancellation signal following initial first-pass pilot cancellation. Residual pilot cancellation is achieved by adding the first-pass cancelled pilot as earlier stored in memory back to the post-traffic cancellation signal, and pilot filtering the resulting signal to generate an improved pilot interference estimate. In an alternative exemplary embodiment, an arbitrary number of iterations may be applied to generate the pilot interference estimate by successively storing each generated pilot interference estimate in memory.

摘要： A hybrid class B channel state information (CSI) reference signal (CSI-RS) scheme is discussed which configures one cell-common beamformed CSI-RS resource for beam tracking and another UE-specific beamformed CSI-RS resource for CSI feedback. The cell-common beamformed CSI-RS resource may be transmitted at a longer periodicity and shared by user equipments (UEs) in the cell. The beamforming may be cycled over a set of predefined weights transparent to UE. The UE-specific beamformed CSI-RS may be transmitted at a shorter periodicity and can be activated dynamically to allow resource sharing among multiple UEs. The UEs will report a CSI for the cell-common beamformed CSI-RS resource which provides a quality indicator for the associated cell-common beam and is utilized by the base station to determine the precoding weight for the UE-specific beamformed CSI-RS resource. Both resources can be configured with different parameter sets, such as number of ports, codebook type, and CSI reporting parameters.

摘要： Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for dynamic frozen polar codes, for example, for control channels. An exemplary method may be performed at the encoder. The method generally includes encoding a stream of bits using a polar code. The encoding includes selecting a first set of channel indices for encoding information bits. The encoding includes selecting a second set of the channel indices smaller than a channel index for a first information bit for encoding fixed frozen bits. The encoding includes selecting remaining channel indices for dynamic frozen (PCF) bits having values based on one or more of the information bits. The method includes transmitting the encoded stream of bits.

摘要： For communication utilizing polar codes, a hybrid automatic repeat request algorithm utilizing incremental redundancy (HARQ-IR) may provide increased throughput by including new data, not based on an original transmission, in a HARQ retransmission. The number of retransmitted bits and new information bits in each HARQ retransmission may be controlled in order to manage a tradeoff between increased throughput and a decreased block error rate (BLER).
