摘要： Certain aspects of the present disclosure relate to methods and apparatus for flexible resource mapping and modulation and coding scheme (MCS) determination in wireless communication systems. According to certain aspects, a method for wireless communications that may be performed by a transmitter is provided. The method generally includes determining MCSs to use for each of multiple portions of a transport block and transmitting the portions of the transport block according to the determined MCSs to a wireless node. Flexible MCS and resource mapping determination may improve demodulation performance for code blocks that are far from pilots.

摘要： Certain aspects of the present disclosure relate to techniques and apparatus for design of hybrid automatic repeat request (HARQ) feedback bits. The method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of blocks, and partitioning each block of the plurality of blocks into a plurality of sections. The method also includes deriving redundancy check information for each section of the plurality of sections, and generating a plurality of codewords, each comprising a block of the plurality of blocks and the redundancy check information for each section of the block, wherein a location of each of the sections in the codewords is determined based on an error rate corresponding to each of the sections.

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： Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching a stream of bits encoded using polar codes. An exemplary method generally includes determining a mother code size (N) for transmitting an encoded stream of bits based, at least in part, on a minimum supported code rate for transmitting the encoded stream of bits (Rmin), a control information size of the encoded stream of bits (K), a number of coded bits for transmission (E), and a maximum mother code size (Nmax), encoding a stream of bits using a polar code of size (N, K) and storing the encoded stream of bits in a circular buffer, and performing rate-matching on the stored encoded stream of bits based, at least in part, on a comparison among the mother code size (N), the control information size of the encoded stream of bits (K), and the number of coded bits for transmission (E).

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.
