BIT ALLOCATION FOR ENCODING AND DECODING

Title:

BIT ALLOCATION FOR ENCODING AND DECODING

Document Type and Number:

WIPO Patent Application WO/2018/126840

Kind Code:

A1

Abstract:

Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
