    Abstract: Aspects of the present disclosure relate techniques for transmitter sharing by a user equipment (UE) for simultaneous communications between multiple radio access technology (RAT) networks. Certain aspects of the present disclosure provide a method for wireless communications by a UE. The method generally includes sharing a single transmit chain via time divisional multiplexing (TDM) for concurrent communication by at least first and second RAT, optionally negotiating an autonomous denial rate for the UE to deny uplink transmissions in the second RAT, detecting or predicting conflicts between scheduled uplink transmissions in the first RAT and a scheduled transmission in the second RAT, and denying uplink transmissions in the second RAT, subject to the negotiated autonomous denial rate if available, in response to detected or predicted.

    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: 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 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: Methods and apparatuses for wireless communications are described. In an aspect, a method and apparatus may include determining that a second transmission is decoded incorrectly in response to a first received indication on a communication channel. The method and apparatus may further include transmitting, on the communication channel, a third transmission and a fourth transmission based on a determination that the second transmission is decoded incorrectly, wherein the third transmission corresponds to a coded bit set of the third transmission including a first group of information bits of a coded bit set of a first transmission and a second group of information bits of a coded bit set of the second transmission and the fourth transmission corresponds to a coded bit set of the fourth transmission including a combination of the coded bit sets of the first transmission, the second transmission, and the third transmission.

    Abstract: 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.
