1. A method for wireless communications performed by a user equipment (UE), comprising:
determining that a configured transmission overlaps in time with a dynamically scheduled transmission; and
deciding, when a time between an end of a downlink control information (DCI) that scheduled the dynamically scheduled transmission and a start of the configured transmission is greater than a threshold processing time, whether to cancel or maintain the configured transmission based on a priority of at least one of the configured transmission or an uplink transmission associated with the dynamically scheduled transmission, wherein:
the priority of the configured transmission and the priority of the uplink transmission associated with the dynamically scheduled transmission are based on associated service types of the configured transmission and uplink transmission associated with the dynamically scheduled transmission;
the configured transmission comprises a configured uplink transmission;
the dynamically scheduled transmission comprises a dynamically scheduled downlink transmission;
the configured uplink transmission comprises at least one of a periodic or semi-persistently scheduled (SPS) sounding reference signal (SRS);
the dynamically scheduled downlink transmission comprises at least one of a semi-persistent or aperiodic channel state information reference signal (CSI-RS) or semi-persistent or aperiodic position reference signal (PRS);
the priority of the configured transmission is determined via at least one of a radio resource control (RRC) message, downlink control information (DCI) activating the configured transmission, or a type of information carried in the configured transmission;
the priority of the uplink transmission associated with the dynamically scheduled transmission is determined by at least one of DCI scheduling the dynamically scheduled transmission or a type of information carried in the uplink transmission associated with the dynamically scheduled transmission; and
the type of information includes at least one of acknowledgement feedback, a serving request, a layer-1 (L1) metric feedback including L1-reference signal received power (RSRP) and L1-signal to interference and noise ratio (SINR), or channel state feedback, wherein the channel state feedback includes at least one of a channel quality indicator (CQI), a precoding matrix indicator (PMI), or a rank indicator (RI).
