AI Technical Summary

Problems solved by technology

However, in the LTE-Advanced system, the downlink bandwidth is composed of multiple carriers. If the UE monitors the PDCCH channels of all the carriers to receive paging messages or monitor system messages, the UE needs to consume a lot of power, which increases the UE power consumption, reducing standby time

Abstract

The embodiment of the invention discloses a carrier sensing method, a terminal device, a base station and a mobility management entity, belonging to the technical field of mobile communication. The invention solves the problems in the prior art that the UE power consumption is high and the standby time is short. The carrier sensing method provided by the embodiment of the invention comprises thata composition carrier is determined and is used as a sensing carrier; and the determined sensing carrier is sensed when user equipment is in idle state. By adopting the invention, the power consumption of the user equipment is reduced and the standby time is increased.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a carrier sensing method, terminal equipment, base station and mobility management entity. Background technique [0002] LTE-Advanced (Long Term Evolution Advanced, further enhancement of the long-term evolution system) is a further enhancement of the LTE (Long Term Evolution, long-term evolution) technology. The requirements of the current LTE-Advanced system require that: LTE UE (User Equipment, user equipment) can normally run on the LTE-Advanced system; meanwhile, the LTE-Advanced UE also needs to be able to run on the LTE system. In addition, in order to meet the requirements of IMT-Advanced (International Mobile Telecommunication Advanced, a further enhancement of the international mobile communication system), support up to 1G peak data rate, 3GPP (3rd Generation Partnership Program, third generation partnership program) LTE-Advanced system At present...
