Abstract
Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to group transmissions into one or more groups, e.g., of various priority levels and/or types of transmissions. The UE may resolve collisions, e.g., according to one or more procedures described herein. The UE may transmit the transmissions according to the resolutions.
Claims20
A method, comprising:
- at a user equipment device (UE):
- connecting to a base station;
- receiving, from the base station, first downlink control information (DCI), scheduling a first transmission, the first DCI indicating a first priority for the first transmission using a priority field of one or more bits;
- receiving, from the base station, second DCI scheduling a second transmission, the second DCI indicating a second priority for the second transmission using the priority field;
- detecting a collision during a symbol of a first slot between the first transmission and the second transmission;
- applying one or more rules to resolve the collision based at least in part on the first priority and the second priority;
- and
- performing a transmission during the first slot according to the resolution;
- and
- receiving, from the base station, third DCI scheduling a third transmission, the third DCI not including the priority field.
