Configured chase-combining reception for new radio (NR) sidelink mode 1

A method of wireless communication, the method comprising:

• receiving, by a first user equipment (UE) from a base station, a transmission grant to transmit a sidelink transmission to a second UE, wherein the transmission grant specifies resources in which the first UE is to transmit the sidelink transmission, and wherein the sidelink transmission includes a data transmission and a sidelink control information (SCI) message;
• transmitting, by the first UE, the sidelink transmission to the second UE over a sidelink based on the transmission grant, the sidelink transmission transmitted during at least one reception occasion of the second UE, wherein each reception occasion of the at least one reception occasion includes a plurality of reception opportunities for the second UE, and wherein transmitting the sidelink transmission includes:
• repeating the SCI message in each reception opportunity of the plurality of reception opportunities of the at least one reception occasion, wherein the second UE is configured to:
• combine the repetition of the SCI message transmitted in one or more reception opportunities of the plurality of reception opportunities to decode the SCI message, wherein, to combine the repetition of the SCI message, the second UE is configured to combine a log-likelihood ration (LLR) calculated for each repetition of the SCI message;
• and
• decode the data transmission using the decoded SCI message.
