Method and apparatus for multiplexing UCI
A method for multiplexing UCI performed by a UE is provided. The method includes: receiving, from a BS, an RRC configuration to configure a sequence that is selected from either a first sequence or a second sequence; receiving, from the BS, a DCI message including an indicator; determining a value corresponding to the indicator based on the configured sequence; and multiplexing a UCI message based on the determined value.
1. A user equipment (UE) comprising:
one or more non-transitory computer-readable media containing computer-executable instructions embodied therein; and
at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor configured to execute the computer-executable instructions to:
receive, from a base station (BS), a Radio Resource Control (RRC) configuration to configure a first sequence associated with a first RRC parameter and a second sequence associated with a second RRC parameter;
receive, from the BS, a first downlink control information (DCI) format including a first indicator and a second DCI format including a second indicator;
determine a first value corresponding to the first indicator based on the first sequence and a second value corresponding to the second indicator based on the second sequence; and
multiplex an uplink control information (UCI) message based on one of the first value and the second value.
2. The UE of claim 1 , wherein the first sequence includes a first plurality of beta offset indexes and the second sequence includes a second plurality of beta offset indexes.
3. The UE of claim 2 , wherein the first indicator indicates one of the first plurality of beta offset indexes and the second indicator indicates one of the second plurality of beta offset indexes.
4. The UE of claim 1 , wherein the first DCI format is for scheduling an enhanced mobile broadband (eMBB) transmission corresponding to low priority and the second DCI format is for scheduling an ultra-reliable and low-latency communications (URLLC) transmission corresponding to high priority.
5. The UE of claim 1 , wherein the second DCI format has fewer bits than the first DCI format.
6. The UE of claim 1 , wherein a length of the first sequence is different from a length of the second sequence.
7. The UE of claim 1 , wherein the UCI message is multiplexed in a physical uplink shared channel (PUSCH) transmission scheduled by one of the first DCI format and the second DCI format.
8. The UE of claim 7 , wherein the first value corresponding to the first indicator or the second value corresponding to the second indicator determines a number of resources for multiplexing the UCI message in the PUSCH transmission.
9. A method for multiplexing uplink control information (UCI) performed by a user equipment (UE), the method comprising:
receiving, from a base station (BS), a Radio Resource Control (RRC) configuration to configure a first sequence associated with a first RRC parameter and a second sequence associated with a second RRC parameter;
receiving, from the BS, a first downlink control information (DCI) format including a first indicator and a second DCI format including a second indicator;
determining a first value corresponding to the first indicator based on the first sequence and a second value corresponding to the second indicator based on the second sequence; and
multiplexing an uplink control information (UCI) message based on one of the first value and the second value.
10. The method of claim 9 , wherein the first sequence includes a first plurality of beta offset indexes and the second sequence includes a second plurality of beta offset indexes.
11. The method of claim 10 , wherein the first indicator indicates one of the first plurality of beta offset indexes and the second indicator indicates one of the second plurality of beta offset indexes.
12. The method of claim 9 , wherein the first DCI format is for scheduling an enhanced mobile broadband (eMBB) transmission corresponding to low priority and the second DCI format is for scheduling an ultra-reliable and low-latency communications (URLLC) transmission corresponding to high priority.
13. The method of claim 9 , wherein the second DCI format has fewer bits than the first DCI format.
14. The method of claim 9 , wherein a length of the first sequence is different from a length of the second sequence.
15. The method of claim 9 , wherein the UCI message is multiplexed in a physical uplink shared channel (PUSCH) transmission scheduled by one of the first DCI format and the second DCI format.
16. The method of claim 15 , wherein the first value corresponding to the first indicator or the second value corresponding to the second indicator determines a number of resources for multiplexing the UCI message in the PUSCH transmission.
