    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may report basis subset selection for a set of beams, where the basis vectors are used for frequency domain compression. To reduce reporting overhead, the UE may transmit two reports indicating the basis vectors. The first report may include first information for the basis vectors and is of a known payload size to both the UE and a base station, while the second report may include second information for the basis vectors and may have a payload size dependent on the first information. The base station may decode the first report and may use the decoded first information to decode the second report. Based on the first and second information, the base station may determine the reported set of basis vectors to use for frequency domain compression and may determine non-zero precoding coefficients.

    Abstract: A device may identify that an incremental redundancy hybrid automatic repeat request (IR-HARQ) scheme is used in association with sequential transmissions of an information bit vector to or from another wireless device, where each transmission in the scheme is associated with a resource size. The device may identify a mother code length for a polar code based at least in part on an aggregate resource size associated with the sequential transmissions. The device may identify an adjusted bit index set for the polar code based at least in part on the IR-HARQ scheme. The device may transmit (or receive), for each transmission of the information bit vector, a respective subset of encoded bits generated by mapping the information bit vector to a set of polarized bit channels of the polar code in accordance with the bit index set.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may perform a first polar code encoding process on a first transmission of a hybrid automatic repeat request (HARQ) process; generate a second transmission of the HARQ process by relocating a portion of bits in less reliable positions of the first transmission to more reliable positions of the second transmission of the HARQ process, wherein the less reliable positions and the more reliable positions are evaluated based at least in part on a channel transform, wherein the channel transform is based at least in part on the first transmission, the second transmission, the first polar encoding process and a second polar encoding process associated with the second transmission; and transmit the second transmission of the HARQ process. Numerous other aspects are provided.
