Rules for dropping overlapping uplink shared channel messages

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more control messages from a network entity scheduling a first and second physical uplink shared channel (PUSCH) messages that overlap at least partially in the time domain. For example, the UE may receive a first control message indicating a set of first PUSCH messages associated with a first rank value and a first quantity of ports and a second control message indicating a second PUSCH message associated with a second rank value and a second quantity of ports. In cases that transmitting both the first and second PUSCH messages exceeds a threshold rank value or a threshold quantity of ports, the UE may refrain from transmitting one of the first or second PUSCH messages.
