Abstract: 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.

Abstract: Apparatus, methods, and computer-readable media for facilitating using of pre-configured UL resources to transmit grant-free data or reference signals are disclosed herein. An example method for wireless communication by a UE includes transmitting, to a base station, a capability of the UE to transmit data in a first message of a random access procedure. The example method also includes receiving pre-configured UL resources from the base station. The example method also includes transmitting data in the first message of the random access procedure using the pre-configured UL resources.

Abstract: 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.

Abstract: Certain aspects of the present disclosure provide techniques for generating and using channel state information reference signals (CSI-RS). In some aspects, a method for generating a Channel State Information-Reference Signal may include: generating a pseudo-random base sequence based on at least a time parameter of the CSI-RS; modifying the pseudo-random base sequence based on at least a frequency parameter of the CSI-RS to form a modified pseudo-random sequence; generating the CSI-RS based on the modified pseudo-random sequence; and transmitting the CSI-RS to a user equipment.

Abstract: 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).

Abstract: Aspects of the disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive an indicator, in a physical downlink control channel (PDCCH) payload, that indicates whether the PDCCH payload includes data or downlink control information (DCI) for obtaining the data, wherein the indicator is an initial state of a cyclic redundancy check that includes a predefined sequence of bits; and obtain at least one of the data or the DCI based at least in part on the indicator. Numerous other aspects are provided.
