Embodiment 1

[0038] Step S102, the serving cell base station configures measurement frequency points, and sends these measurement frequency points to the mobile station;

[0039] Step S104, after receiving the measurement frequency point, the mobile station distributes the measurement bandwidth to each measurement frequency point;

[0040] Step S106, the mobile station performs measurement according to the measurement frequency points and the measurement bandwidth on each measurement frequency point.

[0041] In engineering practice, the base station preferably sends the frequency point of the adjacent cell as the measurement frequency point to the mobile station. The measurement frequency point includes the frequency point of the serving cell in addition to the frequency point of the adjacent cell, but since the frequency point of the serving cell is known to the mobile station, it does not need to be sent.

[0042] There are many ways for the base station to obtain the frequency points ...

Embodiment 2

[0061] In the first embodiment above, the base station needs to send all the measurement frequency points to the mobile station, and the overhead of the air interface is relatively large. This embodiment can be regarded as a further optimization of the above embodiment. Especially for the scenario where the measurement frequency points are evenly distributed in the system bandwidth, but it is also applicable to other scenarios.

[0062] refer to Figure 4 As shown, the measurement frequency point is the center frequency point of the serving cell and the center frequency points of two neighboring cells, and the distance between the frequency points of the two neighboring cells and the frequency points of the serving cell is the same. Therefore, the base station may send the offset value between the frequency point of the adjacent cell and the frequency point of the serving cell to the mobile station. The optimized steps are as follows:

[0063] Step S202, the serving cell bas...

Embodiment 3

[0077] The mobile station provided by the present invention will be described below with reference to the accompanying drawings. The mobile station according to the embodiment of the present invention may include a cell measurement device, and the cell measurement is performed by the device. Such as Figure 5 As shown, the cell measurement device includes: a receiving module 60, configured to receive the measurement frequency points indicated by the base station of the serving cell accessed by the mobile station; a measurement module 62, used to measure frequency points and each frequency point The measurement bandwidth is used for cell measurement.

[0078] Further, in addition to receiving the measurement frequency point, the receiving module 60 also needs to receive the total measurement bandwidth. If the measurement bandwidth parameter is not received, the measurement module 62 uses 6 radio resource blocks as the default for each measurement frequency point. Measurement b...

Abstract

The invention discloses a method and a device for measuring a cell reference signal. The method comprises the following steps that: a base station of a service cell in which a mobile station is located sends measuring frequency points to the mobile station; and the mobile station disperses a total measurement bandwidth to the measurement frequency points according to an instruction of the base station, and carries out measurement. According to the method and the device provided by the invention, the measurement frequency points measured by the mobile station are dispersed, so that a disturbed condition in the entire system bandwidth is sufficiently reflected by a measurement result. Therefore, the problem of inaccurate measurement results caused by that the measurement only can be carried out on six wireless resource blocks in the center of a frequency band of the service cell in the prior art can be solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for a mobile station in a wireless long-term evolution (LTE) system to perform cell reference signal measurement and the corresponding mobile station. The problem of inaccurate physical layer measurement in the prior art is solved. Background technique [0002] With the vigorous development of mobile communication technology, the wireless communication system presents a trend of mobility, broadband and IP, and the competition in the mobile communication market is becoming increasingly fierce. LTE (Long Term Evolution, long-term evolution) is a wireless evolution project carried out by 3GPP, which improves and enhances 3G air access technology and is a technical standard for the transition to the 4G era. LTE-A further expands the performance and functions of LTE and meets the ITU 4G standard; its key technologies include carrier aggregation, relay and hetero...
