摘要： Disclosed are an apparatus and a method for retransmitting a failing RLP frame assigned with a new unique identifier agreed to between the transmitting and receiving RLP processors instead of the original sequence number. The receiving RLP processor requests the transmitting RLP processor to retransmit a failing RLP frame assigned with a new identifier determined by the receiving RLP processor. Responding to the request, the transmitting RLP processor retransmits the failing RLP frame assigned with the requested new identifier instead of the original sequence number.

摘要： Disclosed is a method for handing-off a mobile station receiving packet data over a second channel from a first base station system (BSS) to a second BSS by a base station controller (BSC) in a system in which the mobile station communicates with the first BSS and the second BSS adjacent to the first BSS through a first channel for transmitting a control message, and the mobile station communicates with the first BSS through the second channel for transmitting the packet data. In the method the mobile station measures receiving strengths of pilot channels transmitted from the first BSS and the second BSS, and transmits the measured receiving strengths to the BSC through the first BSS and the second BSS. The first and second BSSs each calculate available transmission power allocable to the second channel and transmits the calculated available transmission power to the BSC. The BSC calculates a sum of the available transmission power and the measured receiving strength of the pilot channel from the first BSS and a sum of the available transmission power and the measured receiving strength of the pilot channel from the second BSS. The BSC transmits a handoff indication message to the second BSS, when the sum of the available transmission power and the measured receiving strength of the pilot channel from the second BSS is higher than the sum of the available transmission power and the measured receiving strength of the pilot channel from the first BSS.

摘要： A method for generating sequence numbers for an RLP frame in a mobile communication system is provided. The method includes the steps of generating a sequence number tree having a plurality of nodes each associated with frame information and a data rate; upon receipt of a sequence number request from an RLP controller, reading, at an RLP sequence number generator, frame information for a designated node from the sequence number tree and providing the read frame information to the RLP controller; and upon receipt of the frame information in response to the sequence number request, transmitting and receiving a frame at the RLP controller.
