Methods and apparatuses for operating in different bandwidth parts (BWPs). A method includes receiving a first synchronization signal and physical broadcast channel (SS/PBCH) block in a first BWP; determining, based on information provided by the first SS/PBCH block, a first control resource set (CORESET) in the first BWP; and receiving a first physical downlink control channel (PDCCH) in the first CORESET. The PDCCH provides a first downlink control information (DCI) format that schedules a reception of a first physical downlink shared channel (PDSCH) providing a system information block (SIB1). The method further includes receiving the first PDSCH, determining a second BWP based on information provided by the SIB1, and receiving a second SS/PBCH block in the second BWP. The second BWP does not include a bandwidth of the first SS/PBCH block. The second BWP does not include a bandwidth of the first CORESET.

The embodiments of the present invention relate to apparatuses and methods for resource management in a multi-carrier system wherein a plurality of component carriers (CCs) is defined per cell. According to a method in an apparatus corresponding to a radio base station, a message is assembled comprising information on the structure of the cell served by the radio base station; the information including one or more CCs used in the cell that is/are available for a user equipment for performing initial access in the cell. The method also comprises, transmitting the assembled message to the user equipment and indicating to the user equipment to what resources to use for random access in the cell. The exemplary embodiments of the present invention also relates to a method in the user equipment, to a radio base station and to a user equipment.

A communication control method according to a first aspect is a method used in cellular communication system including a relay node for relaying communication between a base station and user equipment.
