Prioritization between uplink and sidelink communications
A method performed by a user equipment (UE) configured with an uplink and a sidelink. The method includes determining that a first set of data is to be transmitted in the uplink, assigning a priority value to the first set of data, determining that a second set of data is to be transmitted in the sidelink, assigning a priority value to the second set of data, determining that the first and second set of data are to be transmitted using a same resource at a same time, selecting one of the first set of data or the second set of data to be transmitted first based on at least the first priority value and the second priority value and when the first set of data that is to be transmitted in the uplink is selected, transmitting the first set of data prior to transmitting the second set of data.
