Control channel mother code determination for multi-transmission configuration indication communication

A method for wireless communication, comprising:

• receiving a first codeword on a first set of resources of a control channel using a first receive beam and a second codeword on a second set of resources of the control channel using a second receive beam, the second set of resources having a different number of resources than the first set of resources, wherein the first codeword and the second codeword correspond to control information bits encoded using a polar code having at least one parameter value common to the polar code for the first set of resources and the second set of resources;
• decoding the first codeword and the second codeword according to the polar code and a rate matching procedure;
• and
• obtaining the control information bits based at least in part on the decoded first codeword and the decoded second codeword.

An apparatus for wireless communication, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify control information bits to be transmitted using a first transmit beam on a first set of resources of a control channel and transmitted using a second transmit beam on a second set of resources of the control channel, the second set of resources having a different number of resources than the first set of resources;
• determine parameter values for a polar code based at least in part on the first set of resources and the second set of resources, at least one of the parameter values common to the polar code for the first set of resources and the second set of resources;
• encode the control information bits using the polar code having the determined parameter values to generate a codeword;
• rate match the codeword to the first set of resources and the second set of resources;
• and
• transmit the rate matched codeword on the first set of resources using the first transmit beam and the second set of resources using the second transmit beam.
