Control signal design based on a downlink control information format
Methods and apparatuses for preconfigured uplink resource are disclosed. A method at a remote unit comprises transmitting a data in a predefined resource based on a resource configuration; and receiving a control signal in a first search space, wherein the control signal includes at least one of (1) a response to the data; (2) an updated TA; (3) an updated power; (4) an updated data transmission repetition; (5) a flag of retransmission based on dynamic grant or the predefined resource; (6) a fallback indication; and (7) a predefined resource release indication.
1. A method at a user equipment (UE) remote unit, the method comprising:
transmitting a data in a predefined resource based on a resource configuration; and
receiving a control signal in a first search space, wherein the control signal includes a downlink control information (DCI) format that includes:
a first DCI field comprising a response to the data or a fallback indication; and
a second DCI field comprising an updated data transmission repetition.
2. The method of claim 1 , wherein the response to the data is comprises an acknowledgement (ACK) or a negative ACK (NACK).
3. The method of claim 1 , wherein the updated data transmission repetition is an index of a data transmission repetition set or an index offset to an index corresponding to previously adopted data transmission repetition.
4. The method of claim 1 , further comprising receiving multiple sets of scheduling delay, and determining a set of scheduling delay based on a coverage mode, wherein the control signal further includes an indication of a scheduling delay based on the set of scheduling delay.
5. The method of claim 1 , further comprising receiving multiple reference scheduling delays, and determining a reference scheduling delay based on a coverage mode, wherein the control signal further includes an indication of scheduling delay based on the reference scheduling delay.
6. The method of claim 1 , further comprising receiving multiple sets of repetition number, and determining a set of repetition number based on a coverage mode, wherein the control signal further includes an indication of repetition number based on the set of repetition number.
7. The method of claim 1 , further comprising receiving multiple reference repetition numbers, and determining a reference repetition number based on a coverage mode, wherein the control signal further includes an indication of repetition number based on the reference repetition number.
8. The method of claim 1 , wherein the resource configuration includes at least one of a scheduling delay set, a repetition number set, a reference scheduling delay and a reference repetition number.
9. The method of claim 8 , wherein the control signal further includes an indication of scheduling delay based on the scheduling delay set or the reference scheduling delay.
10. The method of claim 8 , wherein the control signal further includes an indication of repetition number based on the repetition number set or the reference repetition number.
11. The method of claim 1 , further comprising monitoring a second search space for paging message or random access, wherein the second search space is partially or fully overlapped with the first search space in a time or frequency resource.
12. A user equipment (UE), comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
transmit a data in a predefined resource based on a resource configuration; and
receive a control signal in a first search space, wherein the control signal includes a downlink control information (DCI) format that includes:
a first DCI field comprising_a response to the data or a fallback indication; and
a second DCI field comprising an updated data transmission repetition.
13. The UE of claim 12 , wherein the response to the data is comprises an acknowledgement (ACK) or a negative ACK (NACK).
14. The UE of claim 12 , wherein the updated data transmission repetition is an index of a data transmission repetition set or an index offset to an index corresponding to previously adopted data transmission repetition.
15. The UE of claim 12 , wherein the at least one processor is configured to cause the UE to monitor a second search space for paging message or random access, wherein the second search space is partially or fully overlapped with the first search space in a time or frequency resource.
16. A base station, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the base station to:
receive a data in a predefined resource based on a resource configuration; and
transmit a control signal, wherein the control signal includes a downlink control information (DCI) format that includes:
a first DCI field comprising a response to the data or a fallback indication; and
a second DCI field comprising_an updated data transmission repetition.
17. The base unit station of claim 16 , wherein the response to the data is comprises an acknowledgement (ACK) or a negative ACK (NACK).
18. A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
transmit a data in a predefined resource based on a resource configuration; and
receive a control signal in a first search space, wherein the control signal includes a downlink control information (DCI) format that includes:
a first DCI field comprising a response to the data or a fallback indication; and
a second DCI field comprising an updated data transmission repetition.
