Abstract: Examples pertaining to additional bit freezing for polar coding are described. An apparatus performs polar coding to encode a plurality of input subblocks of information bits, frozen bits and optional cyclic redundancy check (CRC) bits to generate a plurality of subblocks of coded bits. The apparatus then transmits at least some of the subblocks of coded bits. In performing the polar coding, the apparatus additionally freezes one of the plurality of input subblocks corresponding to one of the interleaved plurality of subblocks of coded bits which decreases polarization gain due to puncturing.

Abstract: Examples pertaining to bit selection for polar coding incremental-redundancy hybrid automatic repeat request (IR-HARQ) are described. An apparatus (e.g., UE) generates a re-transmission polar code block (CB) in a polar incremental redundancy HARQ (IR-HARQ) procedure. The apparatus then transmits the re-transmission polar CB as a re-transmission of an initial transmission of an initial polar code carrying a plurality of information bits. In generating the re-transmission polar CB, the apparatus selects one or more re-transmission information bits from the plurality of information bits.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a configuration specifying an initial aggregated bandwidth W0 carried on C0 component carriers on which a reception unit (RXU) of the UE is to receive signals. The UE determines a total bandwidth WTOT on which the UE is capable of receiving signals. The UE determines, based on WTOT and W0, an initial hardware limit of Q0′ RXUs that the UE is allowed to activate concurrently. The UE determines an adjusted aggregated bandwidth W1 carried on C1 component carriers on which an RXU of the UE is to receive signals based on a channel condition between the UE and the base station.

Abstract: Examples pertaining to re-transmission cyclic redundancy check (CRC) for polar coding incremental-redundancy hybrid automatic repeat request (IR-HARQ) are described. An apparatus (e.g., UE) encodes a plurality of information bits using a polar code to generate a polar code block (CB). The apparatus performs one or more transmissions of the polar CB using hybrid automatic repeat request (HARQ) by performing an initial transmission of the polar CB and performing a re-transmission of the polar CB with a re-transmission cyclic redundancy check (ReTX CRC).
