Adjacent region configuration method and device

Abstract

The invention discloses an adjacent region configuration method and device. The adjacent region configuration method comprises the steps of, by a base station, receiving capability information reported by UE (User Equipment); if the base station judges that the UE supports switching in a single mode of an LTE system based on the capability information reported by the UE, judging whether the UE supports switching of internal modes of the LTE system based on the capability information reported by the UE; and if not, only sending adjacent region configuration information in the current working mode of the UE to the UE. According to the adjacent region configuration method and device, the capability of the UE for switching frequency division duplex and time division duplex can be obtained exactly, only efficient adjacent region configuration information is sent to the UE, the number of adjacent regions measured by the UE is reduced, the time taken for measurement and reporting is shortened, the electric quantity is saved, the switching speed of a user is speeded up, the signaling loads at the UE side and a base station side are reduced, and the user experience perception is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for configuring adjacent cells. Background technique [0002] LTE (Long Term Evolution, long term evolution) can support FDD (Frequency Division Duplexing, frequency division duplexing) and TDD (Time Division Duplexing, time division duplexing) communication. FDD uses two independent channels to transmit information downwards and upwards respectively; in the mobile communication mode of TDD mode, receiving and transmitting are in different time slots of the same frequency channel, and the receiving and transmitting channels are separated by guaranteed time. [0003] According to the 36.331 protocol, the 13th bit of FGI (Feature Group Indicator) indicates the support for handover within the FDD system of the LTE system or the TDD system of the LTE system; the 30th bit indicates the handover between the FDD system and the TDD system within the LTE s...

Problems solved by technology

For example, some user equipment reports to the base station that the 13th bit of the FGI is 1 and the 30th bit is 0, but the base station reads that the 13th bit of the FGI is 1, and considers that the 30th bit of the FGI is also is 1, so the base station cannot accurately read the handover capability of the user equipment between FDD and TDD, so as to deliver the frequency point information of all neighboring cells of FDD and TDD

The user equipment measures and reports neighboring cell information according to the frequency point information delivered by the base station, and also performs measurement and report for the mode types that do not support handover, which wastes signaling resources and does not save power
