Abstract: Method and apparatus for transmission and reception with polar codes are provided to support up to 16 permutations or transformation mappings. For example, 16 versions of copies able to be soft-combined for PBCH or any other data channel or control channel are suggested if the mother code length is 256 or 512 or 1024. With the new design, up to 16 different versions can be used to soft combined to improve the performance. Some sequences are provided as examples to support 16 different permutation patterns. The inverse of these sequences also have the feature to support 16 different permutation patterns.

Abstract: A communication method and a communication apparatus. A terminal device obtains a first SSB. The terminal device sends a random access preamble corresponding to the first SSB. The random access preamble is carried at a first time domain position. The first time domain position is associated with a timing offset value. The timing offset value is determined based on a round-trip delay between the network device and a first position in an area covered by the network device.
