Title:
INTERLEAVING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029397
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are an interleaving method, deinterleaving method and device for increasing randomness of Polar code interleaving. The method comprises: acquiring a bit sequence for interleaving, the bit sequence for interleaving comprising L sub-sequences, the L sub-sequences comprising S sub-sequence groups, the S sub-sequence groups at least comprising a first sub-sequence group and a second sub-sequence group, the first sub-sequence group at least comprising 2 sub-sequences, the second sub-sequence group at least comprising 1 sub-sequence, where L is a positive integer greater than 1; and interleaving the sub-sequences in the first sub-sequence group using a first interleaving method, and interleaving the sub-sequences in the second sub-sequence group using a second interleaving method or not interleaving the sub-sequences in the second sub-sequence group.
