Abstract: Methods, systems, and devices that support an efficient sequence-based polar code description are described. In some cases, a wireless device (e.g., a user equipment (UE) or a base station) may transmit a codeword including a set of information bits encoded using a polar code or receive a codeword including a set of information bits encoded using a polar code. As described herein, the wireless device may determine the bit locations of the information bits in the polar code based on a partition assignment vector. Specifically, the wireless device may partition bit-channels for one or more stages of polarization and assign information bits to partitions based on the partition assignment vector. Once the bit locations of the information bits are determined, the wireless device may decode a received codeword or transmit an encoded codeword based on the determined bit locations of the information bits.

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: Wireless communications systems and methods are introduced. A wireless communication device may arrange a first encoded information block including a first sub-block having a first bit location and a second sub-block having a second bit location. The second bit location is after the first bit location. The wireless communication device may also position the first location earlier in a decoding order of a receiving second wireless communication than the second bit location. The wireless communication device may transmit the first and second sub-blocks as an encoded information block to the second wireless communication device.

Abstract: Aspects of the disclosure relate to a channel coding and decoding algorithm that provides for generalized polar codes, including the concatenation of a plurality of component codes via one-step polarization. In a further aspect, selection of suitable component codes in this scheme can result in a generalized polar code having a cyclic shift property, such that information can be implicitly communicated according to the magnitude of the cyclic shift. In yet another aspect, a decoding algorithm provides for reliable decoding of such generalized polar codes, including exploitation of time diversity in sequential transmissions. Other aspects, embodiments, and features are also claimed and described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission power for an uplink shared channel communication based at least in part on at least one of a code rate parameter, a block length parameter, or a target block error rate parameter associated with the uplink shared channel communication. In some aspects, the user equipment may transmit the uplink shared channel communication using the transmission power based at least in part on determining the transmission power. Numerous other aspects are provided.

Abstract: In one aspect, a method of wireless communication includes receiving, by a first user equipment (UE), a first transmission from a second UE for a new radio (NR) sidelink channel. The method also includes receiving, by the first UE, a second transmission from a third UE for the sidelink channel. The method further includes transmitting, by the first UE, a feedback transmission based on a medium contention event for the first and second transmissions of the NR sidelink channel and on a range condition. In additional aspects, the feedback transmission is transmitted based on a quality condition, or both a range condition and a quality condition. Other aspects and features are also claimed and described.

The apparatus compares priorities of a first group of transmission signals to determine a first signal from the first group of transmission signals having a highest priority. The first group of transmission signals comprise at least one uplink signal and at least one sidelink transmission signal. The apparatus compares a priority of the first signal from the first group of transmission signals against a reception signal having a highest priority of a second group of reception signals to determine to transmit at least the first signal from the first group of transmission signals or to receive at least one reception signal from the second group of reception signals. The second group of reception signals comprises at least one sidelink reception signal.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.
