Abstract: Disclosed is a method for a 1st moving cell base station to control a handover in a wireless communication system supportive of a moving cell. The present invention includes performing measurement on signals of at least one or more neighbor base stations and determining whether to make a handover based on a result of the measurement. Moreover, the 1st moving cell base station controls the handover not to be made into a 2nd moving cell among the at least one or more neighbor base stations using information on a moving cell dedicated cell ID.

Abstract: The present invention relates to a wireless communication system. In detail, the present invention is a method for transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system includes: receiving information on a resource for the scheduling request (SR) from a base station (BS); transmitting the scheduling request (SR) using the scheduling request (SR) resource transmitted over a control channel; and transmitting a first buffer status report (BSR) using uplink (UL) contention-based resources transmitted over a data channel. The UL contention-based resources are determined based on at least one of the resource for the scheduling request (SR) or an identifier (ID) of the UE.
