Abstract
Aspects of the disclosure relate to wireless communication systems configured to provide techniques for multiplexing dedicated control information for a plurality of users in a single information block and polar coding the information block to produce a polar code block of dedicated control information for transmission over a wireless air interface. The information block may further include group cyclic redundancy check (CRC) information for the information block and individual CRC information for each dedicated control information.
Claims20
A method of wireless communication operable at a scheduled entity, comprising:
- receiving a polar code block comprising multiplexed control information for a plurality of scheduled entities, including the scheduled entity;
- decoding the polar code block utilizing polar decoding;
- locating dedicated control information for the scheduled entity from within the multiplexed control information;
- and
- verifying an integrity of the dedicated control information.
An apparatus configured for polar decoding, the apparatus comprising:
- a processor;
- a memory communicatively coupled to the processor;
- and
- a transceiver communicatively coupled to the processor, wherein the processor and the memory are configured to:
- receive a polar code block comprising multiplexed control information for a plurality of scheduled entities, including the apparatus;
- decode the polar code block utilizing polar decoding;
- locate dedicated control information for the apparatus from within the multiplexed control information;
- and
- verify an integrity of the dedicated control information.
An apparatus configured for polar decoding, the apparatus comprising:
