Title:
COMMUNICATION SYSTEM TO HANDLE MULTIPLE USER EQUIPMENT UPLINK FREQUENCY RETUNNING CAPABILITIES
Document Type and Number:
WIPO Patent Application WO/2018/025893
Kind Code:
A3
Abstract:
A communication system is disclosed in which a base station communicates with machine-type-communication (MTC) devices by dividing the base station's cell bandwidth into (non-overlapping) narrowbands. The base station identifies, based on a communication received from a communication device, a capability of that communication device to retune between narrowbands, and provides, to that communication device, control information for controlling how that communication device retunes between different narrowbands, wherein the control information is based on the identified capability of that communication device to retune between narrowbands.
