A user equipment maps a high priority hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK) information to one or more resource elements (REs), and maps one or more of a low priority HARQ-ACK/NACK information, channel state information (CSI), or uplink-shared channel (UL-SCH) data to REs while rate matching around the mapped high priority HARQ-ACK/NACK REs. A network entity receives an uplink transmission, including high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data mapped to high and low priority HARQ-ACK/NACK REs, CSI REs, and UL-SCH REs, respectively. The low priority HARQ-ACK/NACK REs, the CSI REs, and the UL-SCH REs are rate matched around the high priority HARQ-ACK/N ACK REs. The network entity demaps and decodes the REs of the high and low priority HARQ-ACK/NACK, the CSI, and UL-SCH to obtain the high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data.

Resource element mapping for high and low priority HARQ-ACK/NACK and channel state information on a physical uplink shared channel

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant that schedules uplink shared channel transmissions of a first length. The UE may then determine the actual lengths of the transmissions, which may differ from each other and the scheduled length (e.g., due to conditions of the communication environment, such as the location of slot boundaries). The UE may also identify uplink control information to be multiplexed on the uplink shared channel (e.g., when the scheduled transmission overlaps with a control channel or based on an uplink grant for the uplink control information). The UE may multiplex the uplink control information on the uplink shared channel so as to maintain the same rate-matching scheme and the same coding scheme for each of the transmissions, and transmit the uplink control information in at least one of the transmissions.

Multiplexing uplink control information on uplink shared channel transmissions

Examples of the disclosure relate to generating a packet for transmission over a sidelink resource pool and transmitting the packet to a second UE on a set of sidelink resources of the sidelink resource pool. The set may be selected based on a resource selection procedure of a plurality of resource selection procedures. The resource selection procedure may be selected based at least in part on one or more utilization parameters corresponding to one or more resources of the sidelink resource pool. Other examples, and features are also claimed and described.
