Abstract
A method and apparatus are disclosed from the perspective of a network. In one embodiment, the method includes the network configuring a first serving cell and a second serving cell to a UE, wherein a first PDCCH scheduling a first PDSCH on the first serving cell and a second PDCCH scheduling a second PDSCH on the second serving cell are transmitted via a CORESET of the second serving cell. The method further includes the network not configuring a CORESET configuration for the first serving cell. Furthermore, the method includes the network indicating the UE to receive and/or monitor the first PDCCH based on CORESET configuration of the second serving cell.
Claims20
A method for a network, comprising:
- the network configures a first serving cell and a second serving cell to a UE (User Equipment), wherein a first PDCCH (Physical Downlink Control Channel) scheduling a first PDSCH (Physical Downlink Shared Channel) on the first serving cell and a second PDCCH scheduling a second PDSCH on the second serving cell are transmitted via a CORESET (Control Resource Set) of the second serving cell;
- the network does not configure a CORESET configuration for the first serving cell;
- the network indicates the UE to receive and/or monitor the first PDCCH based on CORESET configuration of the second serving cell.
A method for a UE (User Equipment), comprising:
- the UE receives a configuration of a first serving cell and a second serving cell from a network;
- the UE receives and/or monitors a first PDCCH (Physical Download Control Channel) transmitted on a scheduling CORESET (Control Resource Set) of the second serving cell, wherein the first PDCCH schedules a first PDSCH (Physical Downlink Shared Channel) transmitted on the first serving cell;
- the UE receives and/or monitors a second PDCCH transmitted on the scheduling CORESET of the second serving cell, wherein the second PDCCH schedules a second PDSCH transmitted on the second serving cell;
- the UE receives the second PDSCH via a first TCI (Transmission Configuration Indication) state applied for the scheduling CORESET, if TCI-PresentInDCI is not set as “Enabled” for the scheduling CORESET or if the second PDSCH is scheduled by a first fallback DCI (Downlink Control Information);
- and
- the UE receives the first PDSCH via a second TCI state, wherein the second TCI state is not applied for the scheduling CORESET, if TCI-PresentInDCI is not set as “Enabled” for the scheduling CORESET or if the first PDSCH is scheduled by a second fallback DCI.
A network, comprising:
- a control circuit;
- a processor installed in the control circuit;
- and
- a memory installed in the control circuit and coupled to the processor;
- wherein the processor is configured to execute a program code stored in the memory to:
- configure a first serving cell and a second serving cell to a UE, wherein a first PDCCH scheduling a first PDSCH on the first serving cell and a second PDCCH scheduling a second PDSCH on the second serving cell are transmitted via a CORESET of the second serving cell;
- not configure a CORESET configuration for the first serving cell;
- indicate the UE to receive and/or monitor the first PDCCH based on CORESET configuration of the second serving cell.
