Description

Method for determining cell, related device and system

This application claims the priority of the Chinese Patent Application filed on Dec. 6, 2016, the Chinese Patent Application No. 2016-1110238.5, the title of the invention is "a method for determining a cell, related equipment and system", the entire contents of which are incorporated by reference. In this application.

Technical field

The present application relates to the field of communications, and in particular, to an interference cancellation method and a base station.

Background technique

With the popularity of mobile devices, the pressure on operators' network capacity has soared, and the shortage of spectrum resources is becoming more and more serious. At present, the global licensed band of 5 GHz (GigaHertz, English abbreviation: GHz) also has a considerable portion of the available spectrum. Operators and equipment manufacturers are seeking ways to use this band to increase the carrier capacity of licensed bands. Therefore, the technology of licensed spectrum assisted access (English name: Licensed-Assisted Access, English abbreviation: LAA) came into being.

In the general carrier management mode, the primary cell (English name: Primary Cell, English abbreviation: PCell) delivers A4 measurement configuration to the user equipment (English name: User Equipment, English abbreviation: UE), and the UE reports candidate frequency points to the base station. The A4 measurement report, the base station selects a candidate cell according to the A4 measurement report. However, the measurement capability of the UE is limited. A single UE supports a maximum of 16 frequency points. Since the number of possible frequency points is greater than the measurement capability of the UE, how to make the UE measure the appropriate cell becomes a problem when the secondary carrier configuration measurement is performed. .

The currently adopted scheme is that the base station selects a partial frequency point for the UE to measure among all the candidate frequency points, and sets a timer. If the UE has not measured the appropriate LAA cell before the timer expires, the base station stops the original. With measurement, new measurement control signaling is issued again.

However, in the actual situation, the UE may not be able to measure the appropriate LAA cell in a certain time, which requires the base station to send new measurement control signaling to the UE multiple times, resulting in more air interface signaling. When the UE is in the mobile state, the signals of some LAA cells may be difficult to detect due to the movement of the UE, which is disadvantageous for the base station to select an appropriate LAA cell.

Summary of the invention

The embodiment of the invention provides a cell configuration method, a related device and a system, and the base station only needs to send a signal measurement instruction to the UE at the target measurement frequency point to determine the best access cell of the target measurement frequency signal. It does not need to send signal measurement commands multiple times, which simplifies signaling. In the above manner, even if the UE is in a mobile state, the base station may determine an appropriate access cell according to the preset cell correspondence, and improve the success rate of the base station to select a suitable access cell.
