Embodiment Construction

[0050] As mentioned in the background technology, when the number of cells continues to increase, the number of downlink measurement reference signals between cells is also increasing, and the possibility of interfering with each other is also increasing, especially for the LTE-A system, the above The existence of defects affects the stability of system performance.

[0051] In order to prevent interference of downlink measurement reference signals between cells, an embodiment of the present invention proposes a method for controlling interference of downlink measurement reference signals, which is applied to LTE-A systems.

[0052] Such as figure 1 As shown, it is a method for controlling downlink measurement reference signal interference proposed by an embodiment of the present invention, which specifically includes the following steps:

[0053] Step S101, the base station configures sequences, and / or frequency domain resources, and / or time domain resources for downlink measu...

Abstract

The invention discloses a method for controlling the interference of a downstream measurement reference signal and equipment thereof, which are applied to a high-level long-term evolution LTE-A system. The method comprises the following steps of: a base station configures the sequence, and/or the frequency domain resource, and/or the time domain resource to a downstream measurement reference signal; the base station transmits configuration information of the downstream measurement reference signal to a user terminal; the base station transmits the downstream measurement reference signal to the user terminal respectively through the sequence, and/or the frequency domain resource, and/or the time domain resource; and the user terminal receives the downstream measurement reference signal transmitted by the base station according to the configuration information of the downstream measurement reference signal. With the mode, the invention effectively prevents the downstream measurement reference signals of each block from being interfered on the basis that the downstream measurement reference signal is smoothly transmitted and the system performance is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and equipment for controlling interference of downlink measurement reference signals. Background technique [0002] In a wireless communication system, a pilot signal needs to be sent along with data transmission for channel estimation and channel measurement. The pilot technology can effectively improve the success rate of switching between different carrier frequencies. It is widely used in network optimization. [0003] The pilot signal is an unmodulated direct sequence spread spectrum signal continuously transmitted by the base station, so that the user equipment (User Equipment, UE) can obtain the time limit of the forward code division multiple access channel, provide the relevant demodulation phase reference, and provide signal for each base station A strength comparison by which the UE determines when to perform a handover.
