Abstract
Systems, methods, and instrumentalities are disclosed for a user equipment (UE) to provide feedback in a multi-site scheduling system (e.g., a system where multiple entities may schedule and/or send data to the UE). For example, the UE may receive a first data from a first network entity and a second data from a second network entity. A network entity may include entities that transmit data and/or control information to the UE, e.g., an eNodeB (eNB). The UE may generate feedback relating to received data, such as ACK/NACK information or channel state information (CSI). The UE may send a first feedback relating to the first data in a first subframe and a second feedback relating to the second data in a second subframe.

Claim
1. A method for a user equipment (UE) to provide feedback, the method comprising:
receiving a payload of data, wherein the payload of data comprises a first data from a first network entity via a first MAC instance and a second data from a second network entity via a second MAC instance, the first data being received in accordance with a first downlink assignment from the first network entity, the second data being received in accordance with a second downlink assignment from the second network entity;
sending a first feedback relating to at least the first data in a first subframe to the first network entity via the first MAC instance; and
sending a second feedback relating to at least the second data in a second subframe to the second network entity via the second MAC instance, wherein the first subframe associated with the first feedback sent to the first network entity and the second subframe associated with the second feedback sent to the second network entity are staggered in time, and wherein the first feedback and the second feedback are sent on one or more of a physical shared uplink channel (PUSCH) or a physical uplink control channel (PUCCH).
2. The method of claim 1, wherein the first network entity is a primary eNodeB (eNB) and the second network entity is a secondary eNB.
3. The method of claim 1, wherein the first feedback comprises one or more of a HARQ feedback, a scheduling request (SR), or a channel state information (CSI) feedback.
4. The method of claim 1, wherein the first subframe is comprised in a first set of subframes and the second subframe is comprised in a second set of subframes.
5. The method of claim 1, wherein the first feedback and the second feedback are sent on PUCCH, when simultaneous use of PUCCH and PUSCH is configured.
6. The method of claim 1, wherein the first feedback and the second feedback are sent on the PUCCH, if a PUSCH transmission is not scheduled.
7. The method of claim 1, further comprising monitoring a grant relating to PUSCH transmissions from the first network entity limited to a period during which reception results in sending the first feedback relating to the first data in the first subframe.
8. A user equipment (UE) configured to provide feedback, the UE comprising:
a receiver configured to:
receive payload of data, wherein the payload of data comprises a first data from a first network entity via a first MAC instance and a second data from a second network entity via a second MAC instance, the first data being received in accordance with a first downlink assignment from the first network entity, the second data being received in accordance with a second downlink assignment from the second network entity; and
a transmitter configured to:
send a first feedback relating to at least the first data in a first subframe to the first network entity via the first MAC instance, and
send a second feedback relating to at least the second data in a second subframe to the second network entity via the second MAC instance, wherein the first subframe associated with the first feedback sent to the first network entity and the second subframe associated with the second feedback sent to the second network entity are staggered in time, and wherein the first feedback and the second feedback are sent on one or more of a physical shared uplink channel (PUSCH) or a physical uplink control channel (PUCCH).
9. The UE of claim 8, wherein the first network entity is a primary eNodeB (eNB) and the second network entity is a secondary eNB.
10. The UE of claim 8, wherein the first feedback comprises one or more of a HARQ feedback, a scheduling request (SR), or a channel state information (CSI) feedback.
11. The UE of claim 8, wherein the first subframe is comprised in a first set of subframes and the second subframe is comprised in a second set of subframes.
12. The UE of claim 8, wherein the first feedback and the second feedback are sent on PUCCH, when simultaneous use of PUCCH and PUSCH is configured.
13. The UE of claim 8, wherein the first feedback and the second feedback are sent on the PUCCH, if a PUSCH transmission is not scheduled.
14. The UE of claim 8, further comprising a processor configured to monitor a grant relating to PUSCH transmissions from the first network entity limited to a period during which reception results in sending the first feedback relating to the first data in the first subframe.
15. The method of claim 1, wherein a format and a resource index of a PUCCH transmission carrying feedback for a PDSCH transmission in the first subframe or the second subframe may be determined from one or more of a property of the PDSCH transmission or its corresponding PDCCH assignment.
16. The UE of claim 9, wherein a format and a resource index of a PUCCH transmission carrying feedback for a PDSCH transmission in the first subframe or the second subframe may be determined from one or more of a property of the PDSCH transmission or its corresponding PDCCH assignment.
17. A user equipment (UE) comprising:
a receiver configured to:
receive payload of data, wherein the payload of data comprises a first data from a first network entity via a first MAC instance and a second data from a second network entity via a second MAC instance, the first data being received in accordance with a first downlink assignment from the first network entity, the second data being received in accordance with a second downlink assignment from the second network entity; and
a transmitter configured to:

18. The UE of claim 17, wherein the first data and the second data are received substantially simultaneously.
19. The method of claim 1, wherein each of the first downlink assignment and the second downlink assignment are each a PDSCH assignments.
20. The UE of claim 1, wherein each of the first downlink assignment and the second downlink assignment are each a PDSCH assignments.
