1. A method performed by a user equipment, UE, configured for dynamic bandwidth part, BWP, switching between an active BWP and a target BWP, the method comprising:
receiving, from a network node, an indication of resource blocks, selected by the network node to be used by the UE in the target BWP, in a resource allocation field of a downlink control information in the active BWP, the resource allocation field comprising information bits for allocating one or more resource blocks for the target BWP;
determining a target BWP resource allocation type based on a relationship between the resources allocated for the target BWP and resources allocated for the active BWP, the target BWP resource allocation type indicating whether the information bits of a resource allocation field in a downlink control information comprise a bitmap corresponding to one or more resource block groups or an integer value corresponding to a starting position and a length of the allocation; and
interpreting the information bits based on the determined target bandwidth part resource allocation type.
