Abstract: Methods, systems, and devices for wireless communication are described. In a new radio (NR) system, a wireless device may identify a candidate codeword for a channel employing polar coding. The wireless device may perform a decoding operation on the candidate codeword to determine candidate decoding paths corresponding to encoded information bits. The decoding operation may include multiple decoding path candidates, each of which is associated with a path metric. The wireless device may evaluate a spread metric to determine if a decoding hypothesis is incorrect or if the received codeword is too corrupted for decoding. The spread metric may be based on the path metrics of the decoding paths or soft metrics of the decoding paths determined based on a subset of bit channels of the polar code. The wireless device may normalize the spread metric to compensate for signal-to-noise ratio (SNR) variation.

Abstract: Methods, systems, and devices for outputting of codeword bits for transmission prior to loading all input bits. An example encoder may have multiple encoding branches. The encoder may divide the encoding branches into first and second encoding branch subsets, outputs of the first encoding branch subset being independent of inputs to the second encoding branch subset. The encoder may generate first and second subsets of output bits of a codeword in first and second encoding operations, the generating comprising inputting information bits of an information bit-vector and at least one frozen bit into respective encoding branches of the plurality of encoding branches and generating the first subset of output bits using the first encoding branch subset prior to generating the second subset of output bits using the second encoding branch subset. The encoder may output the first subset of output bits prior to outputting the second subset of output bits.

Abstract: Methods, systems, and devices for wireless communication are described. In a new radio (NR) system, a wireless device may encode control information into a codeword using a polar code. The device may prioritize certain information within the codeword due to the time criticalness of that information for processing at a receiving device. For example, information related to frequency allocation may be encoded such that the receiving device may decode the frequency allocation information early in the decoding process. The device may include partial parity checks throughout the codeword, so that the receiving device may test whether the decoded bits for the prioritized information pass a parity check, and may then send these decoded bits for processing before completing decoding of the codeword. In some cases, the device may encode the information to be transmitted using multiple evenized codewords, or using a single consolidated codeword.

Abstract: Multicasting resource allocation information per aggregation level is enabled. A device allocates resources to UEs according to aggregation level. At each level, a control message includes a bitmap, where each bit corresponds to a different resource, an array, and an ID field for dynamic mapping to the bitmap. The placement order value of an ID in the field is stored at locations in the array. The index value for those locations in the array identifies which asserted bits in the bitmap correspond to the resource allocation for a UE at the level. The control message is multicast to the UEs specified at the aggregation level. The bitmap may have the same length at each level, or have reducing length at lower levels with the removal of bits already asserted at higher levels. The UE reconstructs the bitmap from the higher level bitmaps and the bitmap for the current level.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for increasing decoding performance and/or reducing decoding complexity. An exemplary method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of payload sections, deriving redundancy check information for each respective payload section of the plurality of payload sections, merging the redundancy check information for each payload section with the plurality of payload sections to form a sequence of bits, and generating a codeword by encoding the sequence of bits using an encoder. Other aspects, embodiments, and features are also claimed and described.

Abstract: The disclosure relates in some aspects to techniques for use in systems where a plurality of devices with different priority levels share a common set of resources for communication (e.g., downlink transmissions). Certain aspects provide a new indication channel and a procedure to signal scheduling information (e.g., priority information). Such information may serve as an indicator for possible new grants. Such information may additionally serve as an indicator for higher-priority scheduling conflicts or include explicit commands that result from conflicts (e.g., conflicts relating to puncturing of resources allocated for transmissions to lower priority devices).
