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.
Claims30
A method of wireless communication, comprising:
- generating an information block comprising dedicated control information for each of a plurality of scheduled entities, wherein each of the dedicated control information comprises a same size;
- generating individual cyclic redundancy check (CRC) information for each of the respective dedicated control information;
- generating group CRC information for the information block;
- encoding the information block, including the individual CRC information and the group CRC information, utilizing polar coding to generate a polar code block;
- and
- transmitting the polar code block over a wireless air interface.
An apparatus configured for polar coding, the apparatus comprising:
- a processor;
- a memory communicatively coupled to the processor;
- and
- a transceiver communicatively coupled to the processor, wherein the processor is configured to:
- generate an information block comprising dedicated control information for each of a plurality of scheduled entities, wherein each of the dedicated control information comprises a same size;
- generate individual cyclic redundancy check (CRC) information for each of the respective dedicated control information;
- generate group CRC information for the information block;
- encode the information block, including the individual CRC information and the group CRC information, utilizing polar coding to generate a polar code block;
- and
- transmit the polar code block over a wireless air interface.
An apparatus configured for polar coding, the apparatus comprising:
- means for generating an information block comprising dedicated control information for each of a plurality of scheduled entities, wherein each of the dedicated control information comprises a same size;
- means for generating individual cyclic redundancy check (CRC) information for each of the respective dedicated control information;
- means for generating group CRC information for the information block;
- means for encoding the information block, including the individual CRC information and the group CRC information, utilizing polar coding to generate a polar code block;
- and
- means for transmitting the polar code block over a wireless air interface.
