Embodiment Construction

[0047] In order to solve the problems in the prior art that the total received bandwidth power (RTWP) peak occurs due to the high transmit power of the terminal equipment, the present invention reduces the transmit After the alternate sequence of the power command and the increase transmit power command, the increase transmit power command is added to generate a transmission power control (TPC) command, and the terminal device adjusts the transmit power according to the TPC command to control the increase speed of the transmit power.

[0048] The base station configures the TPC parameter value in advance, and determines the alternate sequence of the transmit power reduction command and the transmit power increase command according to the parameter value.

[0049]Described TPC parameter value is different according to the difference of channel state, as according to channel is the first channel, or is the same frequency switching channel, or different frequency switching channel...

Abstract

A method for controlling power of different frequency hard-switch in base station includes launching different frequency hard-switch by terminal device, sending transmission power control to command to terminal device by base station in cell of terminal device to indicate terminal device to raise emission power, generating said command in mode of adding command to raise emission power after alternative series of decreasing emission power command and increasing emission power command before radio link synchronization, regulating emission power as per said command by terminal device . The communication system utilizing said method is also disclosed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for power control of inter-frequency hard handover in a base station. Background technique [0002] In order to deal with the crossover caused by movement in the connected mode to ensure the continuity of coverage and to adjust the load, the Wideband Code Division Multiple Access (WCDMA) system has handover functions, including softer handover, soft handover, same frequency / Inter-frequency hard handover and handover between systems. [0003] The main differences between soft handover and hard handover are as follows: [0004] Soft handover is added first and then disconnected, that is, the terminal equipment adds a link that is about to enter the new cell while the original link is maintained, and deletes the original link after the quality of the link in the new cell reaches a certain threshold to complete a handover ; hard handover is to br...
