Title:
RATE-MATCHING SCHEME FOR CONTROL CHANNELS USING POLAR CODES
Document Type and Number:
WIPO Patent Application WO/2018/127172
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching control channels using polar codes. An exemplary method generally includes encoding a stream of bits using a polar code, determining a size of a circular buffer for storing the encoded stream of bits based, at least in part, on a minimum supported code rate and a control information size, and performing rate-matching on stored encoded stream of bits based, at least in part, on a mother code size, N, and a number of coded bits for transmission, E.
