Abstract
Systems and methods for determining priority of different types of overlapping transmission are provided. When an ACK/NACK PUCCH resource overlaps with a scheduling request PUCCH resource, based on the determined relative priorities of the ACK/NACK and the scheduling request, a wireless device can determine which transmission should be prioritized and transmitted.
Claims24
A method performed by a wireless device, the method comprising:
- determining that an acknowledgement/negative acknowledgement (ACK/NACK) transmission and a scheduling request (SR) transmission will overlap in Physical Uplink Control Channel (PUCCH) resources;
- determining a priority associated with the ACK/NACK transmission, wherein the priority associated with the ACK/NACK transmission is determined at least in part based on a Downlink Control Information (DCI) message transmitted on a Physical Downlink Control Channel (PDCCH) and a priority level associated with a PUCCH resource carrying the ACK/NACK transmission;
- comparing the priority associated with the ACK/NACK transmission with a priority associated with the SR transmission to determine which transmission has a higher relative priority;
- and
- transmitting the transmission with the higher relative priority.

A wireless device comprising a radio interface and processing circuitry configured to:
- determine that an acknowledgement/negative acknowledgement (ACK/NACK) transmission and a scheduling request (SR) transmission will overlap in PUCCH resources;
- determine a priority associated with the ACK/NACK transmission, wherein the priority associated with the ACK/NACK transmission is determined at least in part based on a Downlink Control Information (DCI) message transmitted on a Physical Downlink Control Channel (PDCCH) and a priority level associated with a PUCCH resource carrying the ACK/NACK transmission;
- compare the priority associated with the ACK/NACK transmission with a priority associated with the SR transmission to determine which transmission has a higher relative priority;
- and
- transmit the transmission with the higher relative priority.
