Claim of US Patent No. 10,602,519

1. A method performed by a user equipment, UE, for switching between an active bandwidth part, BWP, and a target BWP, each of the respective BWPs comprising at least one resource block for use by the UE, the method comprising:receiving a resource allocation field in a downlink control information in the active BWP, the resource allocation field comprising information bits for allocating the at least one resource block in the target BWP;
interpreting the resource allocation information bits based on a target BWP resource allocation type, the target BWP resource allocation type being determined in dependence of a relationship between the at least one resource block for the target BWP and at least one resource block of the active BWP, the relationship corresponding to a difference in a number of information bits in the resource allocation field of the downlink control information in the active BWP compared to a number of information bits in a resource allocation field for the target BWP, the target BWP resource allocation type indicating whether the information bits comprise one of:
a bitmap corresponding to at least one resource block group; and
an integer value corresponding to a starting position and a length of the allocation; and
switching to the target BWP for one of a transmission and reception on the allocated target BWP resource blocks.
