Multi-trp transmission

A method implemented at a user equipment (UE), comprising:

• receiving configuration of a first bandwidth part (BWP) and a second BWP for a first Transmission and Reception Point (TRP), wherein the first TRP is one of multiple TRPs in communication with the UE in a multi-TRP operation, and each of the multiple TRPs are in communication with the UE within the first BWP;
• and
• receiving from the first TRP, within the first BWP, a first Physical Downlink Control Channel (PDCCH) comprising a first Downlink Control Information (DCI) format scheduling the UE for the first TRP, wherein,
• a second PDCCH, comprising a second DCI format scheduling the UE for a second TRP of the multiple TRPs, is received from the second TRP within the first BWP,
• the first DCI format comprises a field indicating a BWP switching from the first BWP to the second BWP, and
• the UE is scheduled within the second BWP from the first TRP and the second TRP, after switching from the first BWP to the second BWP.

A method implemented at a network device, comprising:

• transmitting to a User Equipment (UE), configuration of a first bandwidth part (BWP) and a second BWP for a first Transmission and Reception Point (TRP), wherein the first TRP is one of multiple TRPs in communication with the UE in a multi-TRP operation, and each of the multiple TRPs are in communication with the UE within the first BWP;
• and
• transmitting to the UE, within the first BWP, a first Physical Downlink Control Channel (PDCCH) comprising a first DCI format scheduling the UE for the first TRP, wherein,
• a second PDCCH, comprising a second DCI format scheduling the UE for a second TRP of the multiple TRPs, is transmitted to the UE within the first BWP,
• the first DCI format comprises a field indicating a BWP switching from the first BWP to the second BWP, and
• the UE is scheduled within the second BWP from the first TRP and the second TRP, after switching from the first BWP to the second BWP.
