Method, device and system for realizing identification of carrier wave types

Abstract

This invention discloses a method, a device and a system for realizing identification of carrier wave types. Corresponding type information of carrier waves is configured in the carrier wave and the configured type information of the carrier wave is transmitted by a system side network element according to the deployed carrier wave type. The technology realizing the identification of carrier wave types disclosed by the invention can facilitate the new version UE to effectively identify the carrier wave types, reduce the accessing time of the UE and make the UE save power.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing carrier type identification. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (Qos) of mobile communication. Therefore, before the third generation of mobile communication (3G) has not yet Before large-scale commercial use, the research and development work on the next generation mobile communication system has already started, and the typical one is the Long Term Evolution (LTE, Long Term Evolution) project initiated by the Third Generation Partnership Project (3GPP). With the further evolution of the network, LTE-A (Enhanced LTE), as an evolution system of LTE, can provide up to 100MHz spectrum bandwidth, support more flexible and higher-quality communication, and the...

Problems solved by technology

[0005] In this way, there will be two carrier types in LTE R12, the independently operated NCT and the backward compatible carrier. One is NCT, the other is backward compatible carrier, and the channel configuration / data scheduling transmission / signaling configuration / reference signal transmission in the two carriers are not exactly the same, but when the user equipment (UE) accesses the LTE R12 carrier The carrier type cannot be identified, causing the UE to have the following problems: 1. A new version of UE (such as LTE R12UE, the same below) needs to try to receive system information, reference signals, etc. according to the mechanism of compatible carriers and the new mechanism of NCT, which makes UE consumes electricity and time

2. UEs of old versions (such as UEs before LTE R12) receive system information, reference signals, etc. according to the compatible carrier mechanism. If encountering NCT, the UE may fail to access NCT after some attempts at this time, resulting in UE consumes electricity and time
