Working method and system of enhanced long-term evolution system terminal

Abstract

The invention discloses a working method and a working system of an enhanced long-term evolution system terminal, comprising: the enhanced long-term evolution system terminal in a connected state works independently on a non-backward compatible carrier wave without the information support on a backward compatible carrier wave. The method is simple and effective; when transmitting data on a non-backward compatible composition carrier wave, an LTE-A terminal can work independently on one composition carrier wave of such type, without monitoring other composition carrier waves, thus being capable of providing a flexible work mechanism for the LTE-A terminal and also being conducive to the power saving of the LTE-A terminal; and the LTE-A terminal resides only on the backward compatible carrier wave when in idle state, the working mode simply and effectively resolves the problem that the downlink composition carrier wave is not clear in the process of random access. And the method has smaller effect on protocol modification.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a working method and system for an LTE-A terminal in an enhanced Long Term Evolution-Advanced (LTE-A) system. Background technique [0002] With the development of the mobile industry and the increasing demand of users for mobile data services, people have higher and higher requirements for the speed and quality of service (Qos) of mobile communications. ) before large-scale commercial use, relevant technical personnel have already started the research and development work on the next generation mobile communication system, and the typical one is the long-term project initiated by the 3rd Generation Partnership Project (3GPP). In the Long Term Evolution (LTE for short) project, the highest spectrum bandwidth that the LTE system can provide is 20 MHz (megahertz). With the further evolution of the network, the LTE-A system, as an evolution system of the LTE system, can...

AI Technical Summary

Problems solved by technology

For non-backward compatible camping carriers, when idle LTE-A terminals can also camp on, the problem of unclear downlink component carriers in the initial access process of cell-specific asymmetric carrier aggregation still needs to be resolved. The impact needs to be evaluated; for non-backward compatible non-resident carriers, LTE-A terminals still need backward compatible component carriers to work together in the connected state, which is limited by other backward compatible component carriers
