TL;DR: In this paper, a method for handover in a mobile station includes sending a scan request message for scanning a downlink (DL) beam with respect to a serving base station (BS) and a neighboring BS, to the serving BS, and receiving a scan response message; determining the DL beam for the MS by performing scanning with the BS and the neighboring BS based on the scan response messages.

TL;DR: In this paper, the authors propose a method for controlling the operational state of a medium access control layer in a broadband wireless access communication system, which includes the steps of performing an uplink access of a contention-based scheme to an access point using resources required to perform the uplink accessing according to the contentionbased scheme when data to be transmitted in an access state is detected.

TL;DR: In this paper, an apparatus and method for transmitting a signal in a communication system using a low density parity check (LDPC) code is provided for transmitting an information word at a coding rate, where an additional pattern is generated when the HARQ scheme to be applied to the LDPC codeword is a partial chase combining (CC) scheme.

TL;DR: In this article, a handover request message from the mobile station to the serving base station is transmitted when it is detected that a performance of a handoff is necessary; and transmitting an handover indication message containing handover cancel information to the base station when the mobile stations determines a cancel of the handover while the mobile unit is being handed over to one or more target base stations by the service provider.

TL;DR: In this paper, the authors propose a method for recognizing whether a BS retains connection information in a mobile communication system including the serving BS for providing a service to the MSS and a target BS adjacent to the BS.
