Abstract
Certain aspects of the present disclosure provide techniques for utilizing and processing repeated DCI transmissions that schedule common uplink or downlink transmissions. The techniques allow a UE to decide which repeated DCI to use for determining resources for the uplink or downlink transmissions.
Claims19
A method for wireless communications by a user equipment (UE), comprising:
- detecting at least first downlink control information (DCI) and second DCI that both indicate same or similar scheduling information for a common uplink data transmission or a downlink data transmission;
- selecting, based at least in part on determining the second DCI is a repetition of the first DCI, at least one of the first or second DCI to use for determining scheduling parameters to use for the uplink data transmission, or for reception of the downlink data transmission, or for an uplink control information (UCI) transmission to provide feedback for the downlink data transmission;
- and
- utilizing the scheduling parameters to at least one of process the DL data transmission or send the uplink data transmission or UCI transmission.

A method for wireless communications by a network entity, comprising:
- transmitting at least first downlink control information (DCI) and second DCI that both indicate same or similar scheduling information for a common uplink or downlink transmission;
- monitoring the first and second resources for the uplink transmission or UCI transmission;
- and
- selecting transmission parameters and a beam used for the first or second DCI for subsequent transmissions, depending on which of the first or second resources the uplink transmission or UCI transmission is detected.
1 more element
An apparatus for wireless communications by a user equipment (UE), comprising:
- a processor, a memory coupled with the processor, wherein the memory comprises instructions executable by the processor to cause the apparatus to:
- detect at least first downlink control information (DCI) and second DCI that both indicate same or similar scheduling information for a common uplink data transmission or a downlink data transmission;
- select, based at least in part on determining the second DCI is a repetition of the first DCI, at least one of the first or second DCI to use for determining scheduling parameters to use for the uplink data transmission, or for reception of the downlink data transmission, or for an uplink control information (UCI) transmission to provide feedback for the downlink data transmission;
- and
- utilize the scheduling parameters to at least one of process the DL data transmission or send the uplink data transmission or UCI transmission.
