Abstract: A configuration to determine a starting bit for PUSCH repetition with TBS scaling. The apparatus determines a TBS of a PUSCH transmission based at least in part on a set of PUSCH resources corresponding to a set of PUSCH repetitions for transmission over a repetition unit comprising a plurality of slots. The apparatus determines a starting bit location of each code block of the PUSCH transmission for a first slot of the plurality of slots. The apparatus determines a different starting bit location of each code block of the PUSCH transmission for each slot of the plurality of slots following the first slot, wherein each of the different starting bit locations for each slot following the first slot is based on a two level RV cycling. The apparatus transmits the PUSCH repetitions, each slot comprising encoded data based on respective starting bit locations.

Abstract: Aspects of the present disclosure provide techniques for determining frequency hopping for physical uplink shared channel (PUSCH) repetitions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least first and second part frequency domain resource allocations (FDRAs) for a first physical uplink shared channel (PUSCH) transmission occasion, transmits a transport block (TB) via at least first and second parts of a physical uplink shared channel (PUSCH) on the first and second part FDRAs with first and second precoders during the first PUSCH transmission occasion, determines at least first and second part FDRAs for a second PUSCH transmission occasion based on a frequency hopping scheme, and transmits the same TB via first and second parts of the PUSCH on the determined first and second part FDRAs with first and second precoders during the second PUSCH transmission occasion.

Abstract: Methods, systems, and devices for wireless communication are described for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a set of random access opportunities over which to transmit a preamble associated with a random access procedure, each random access opportunity associated with a set of one or more uplink data opportunities. The UE may identify a repetition parameter for an uplink message. The UE may select a random access opportunity from the set of configured random access opportunities for transmitting the preamble based at least in part on the repetition parameter. The UE may transmit the preamble on the selected random access opportunity. The UE may transmit one or more repetitions of the uplink message based at least in part on the set of one or more uplink data opportunities associated with the selected random access opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.
