Prioritization of services for control and data transmission for new radio systems
Methods, systems, and storage media are described for the prioritization of services for control and data transmission for new radio (NR) systems. In particular, some embodiments may be directed to the prioritization of hybrid automatic repeat request-acknowledgment (HARQ-ACK) transmissions. Other embodiments may be described and/or claimed.
1. An apparatus of a user equipment (UE) comprising:
memory to store uplink (UL) resource information; and
processing circuitry, coupled with the memory, to:
receive first UL resource information that includes an indication of a first UL resource in a serving cell of a first hybrid automatic repeat request-acknowledgement (HARQ-ACK), the first HARQ-ACK associated with a first HARQ codebook;
receive second UL resource information that includes an indication of a second UL resource in a serving cell of a second HARQ-ACK, the second HARQ-ACK associated with a second HARQ codebook;
store the first UL resource information and second UL resource information in the memory;
determine that the first UL resource and the second UL resource overlap, and that the second HARQ-ACK transmission is triggered by a second downlink control information (DCI) message and the first HARQ-ACK transmission is triggered by a first DCI message, wherein the first DCI message is to indicate a first priority of the first codebook and the second DCI message is to indicate a second priority of the second codebook, the second priority higher than the first priority; and
based on the determination, perform the second HARQ-ACK transmission using the second resource, and drop the first HARQ-ACK transmission.
2. The apparatus of claim 1 , wherein the first codebook has a lower priority than the second codebook.
3. The apparatus of claim 2 , wherein the first UL resource and the second UL resource overlap in time.
4. The apparatus of claim 2 , wherein the first UL resource and the second UL resource overlap in frequency.
5. The apparatus of claim 1 , wherein the first codebook is part of a first HARQ-ACK codebook group that supports a single physical uplink control channel (PUCCH) transmission with HARQ-ACK within a slot, or supports multiple PUCCH transmissions with HARQ-ACK.
6. The apparatus of claim 5 , wherein the processing circuitry is further to determine, based on dynamic control information (DCI), that the first HARQ-ACK codebook group has a lower priority than the second HARQ-ACK codebook group.
7. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a user equipment (UE) to:
receive an indication of a first UL resource in a serving cell of a first hybrid automatic repeat request-acknowledgement (HARQ-ACK), the first HARQ-ACK associated with a first HARQ codebook;
receive an indication of a second UL resource in a serving cell of a second HARQ-ACK, the second HARQ-ACK associated with a second HARQ codebook;
determine:
a first priority associated with the first HARQ-ACK codebook and a second priority associated with the second HARQ-ACK codebook, wherein the first priority is lower than the second priority;
that the first UL resource and the second UL resource overlap; and
that the second HARQ-ACK transmission is triggered by a second downlink control information (DCI) message and the first HARQ-ACK transmission is triggered by a first DCI message, wherein the first DCI message is to indicate a first priority of the first codebook and the second DCI message is to indicate a second priority of the second codebook, the second priority higher than the first priority; and
based on the determination, perform the second HARQ-ACK transmission using the second resource, and drop the first HARQ-ACK transmission.
8. The one or more non-transitory computer-readable media of claim 7 , wherein the first HARQ-ACK codebook group has a lower priority than the second HARQ-ACK codebook group.
9. The one or more non-transitory computer-readable media of claim 8 , wherein the first UL resource and the second UL resource overlap in time.
10. The one or more non-transitory computer-readable media of claim 8 , wherein the first UL resource and the second UL resource overlap in frequency.
11. The one or more non-transitory computer-readable media of claim 7 , wherein the first codebook is part of a first HARQ-ACK codebook group that supports a single physical uplink control channel (PUCCH) transmission with HARQ-ACK within a slot, or supports multiple PUCCH transmissions with HARQ-ACK.
12. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a next-generation NodeB (gNB) to:
generate a first message that includes an indication of a first UL resource in a serving cell of a first hybrid automatic repeat request-acknowledgement (HARQ-ACK), the first HARQ-ACK associated with a first HARQ codebook;
encode the first message for transmission to a user equipment (UE);
generate a second message that includes an indication of a second UL resource in a serving cell of a second HARQ-ACK, the second HARQ-ACK associated with a second HARQ codebook;
encode the second message for transmission to the UE;
encode a first downlink control information (DCI) message for transmission to the UE, wherein the first DCI message is to trigger a first HARQ-ACK transmission; and
encode a second DCI message for transmission to the UE, wherein the second DCI message is to trigger a second HARQ-ACK transmission, and wherein the first DCI message is to indicate a first priority of the first codebook and the second DCI message is to indicate a second priority of the second codebook, the second priority higher than the first priority.
13. The one or more non-transitory computer-readable media of claim 12 , wherein the first UL resource and the second UL resource overlap in time.
14. The one or more non-transitory computer-readable media of claim 12 , wherein the first UL resource and the second UL resource overlap in frequency.
15. The one or more non-transitory computer-readable media of claim 12 , wherein the first codebook is part of a first HARQ-ACK codebook group that supports a single physical uplink control channel (PUCCH) transmission with HARQ-ACK within a slot.
16. The one or more non-transitory computer-readable media of claim 12 , wherein the first codebook is part of a first HARQ-ACK codebook group that supports multiple PUCCH transmissions with HARQ-ACK.
17. The one or more non-transitory computer-readable media of claim 15 , wherein the first HARQ-ACK codebook group has a lower priority than the second HARQ-ACK codebook group.
