- the priority can be indicated in DL assignment or as part of DL SPS configuration.
- the priority can be indicated in UL grant or as part of UL configured grant Type 1 or Type 2 configuration.
- the priority can either be derived from DL assignment or UL grant triggering dynamic PUCCH/UCI transmission or be a part of PUCCH resource configuration.
- the UE applies the priorities to decide on whether to transmit/process each of them in case of overlap: In case of PDSCH reception scheduled in overlapped resources, a UE can be expected to process the PDSCH with higher associated priority; in accordance with certain specifications, the UE cannot expect to be scheduled with multiple unicast PDSCH reception if the
- PDSCHs are scheduled with same priority levels, where the overlap in resources imply either time and frequency domain resources or resources only in the time domain; in case of PUSCH transmission scheduled in overlapped resources, a UE can be expected to transmit the PUSCH with higher associated priority and drop at least overlapped part of the lower priority PUSCH. In case of equal priority, the UE can follow its existing behavior; in case of PUxCH (either PUSCH or PUCCH) transmission scheduled in overlapped resources, the UE can be expected to transmit the higher priority PUxCH and drop the lower priority PUxCH. In case of equal priorities, the UE does multiplexing or dropping according to its existing behavior.

- a twenty-second example can include the twenty-first example, wherein the prioritization rule differentiates handling of different service types / priorities of uplink control information (UCI) based on different service requirements that correspond to UCIs, respectively, or different data resources and UCIs with the different service types / priorities.
- UCI uplink control information
- a twenty-third example can include the twenty-first or twenty-second example, wherein the one or more indications activate the prioritization rule by indicating to drop a first transmission of a first service type / priority over a second transmission of a second service type / priority based on the prioritization rule, wherein the first service type / priority comprises an enhanced Mobile Broadband (eMBB) communication and the second service type / priority comprises an Ultra-Reliable Low- Latency Communication (URLLC).
- eMBB enhanced Mobile Broadband
- URLLC Ultra-Reliable Low- Latency Communication
- various aspects or features described herein can be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques.

- Communications media embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media.
- modulated data signal or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals.
- communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.
- An exemplary storage medium can be coupled to processor, such that processor can read information from, and write information to, storage medium.
- storage medium can be integral to processor.
- processor and storage medium can reside in an ASIC.
- ASIC can reside in a user terminal.
- processor and storage medium can reside as discrete components in a user terminal.
- the processes and/or actions of a method or algorithm can reside as one or any combination or set of codes and/or instructions on a machine-readable medium and/or computer readable medium, which can be incorporated into a computer program product.
