Processing of uplink transmission collisions in the time domain

Abstract

A UE is provided, comprising a processor and one or more non-temporary computer-readable media storing computer-executable instructions for handling uplink transmit collisions in the time domain. The processor is configured to determine several PUSCH iterations for uplink (UL) physical uplink shared channel (PUSCH) transmits of the UE. The processor is configured to group PUSCH iterations into one or more groups, each group having two or more PUSCH iterations carrying UL data for PUSCH transmits. The processor is configured to determine whether at least one PUSCH iteration in a first group of two or more PUSCH iterations overlaps with a UL physical uplink control channel (PUCCH) in the time domain. After determining that at least one PUSCH iteration overlaps with a UL PUCCH at least partially, the processor is configured to stop UL PUSCH transmits for at least the first group of PUSCH iterations.
