Device and method for acquiring RSRQ (Reference Signal Receiving Quality)

Abstract

The invention provides a device and a method for acquiring RSRQ (Reference Signal Receiving Quality). The device for acquiring the RSRQ comprises a radio frequency antenna, a signal processor, at least one data selector and a measurer, wherein the radio frequency antenna is used for acquiring a receiving signal of a cell; the receiving signal comprises at least one reference signal; the signal processor is used for processing the receiving signal to acquire a plurality of candidate signals; the plurality of candidate signals have different bandwidths; the at least one data selector is connected with the signal processor; each of the at least one data selector is respectively used for selecting one to-be-measured signal from the lurality of candidate signals; and the measurer is used for acquiring the RSRQ on the basis of the to-be-measured signal. According to the device and the method which are provided by the invention, for different cases, different bandwidths of candidate signals can be selected, and in a suitable environment, a small bandwidth can be selected to measure the RSRQ and good measurement performance can be ensured, and thus, compared with an existing WB-RSRQ measurement method, the method is low in hardware cost and low in power consumption and has adjustable flexibility.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a device and method for obtaining the receiving quality of a reference signal. Background technique [0002] Reference Signal Receiving Quality (Reference Signal Receiving Quality, RSRQ) is mainly used to measure the receiving quality of a cell reference signal. The reference signal reception quality depends on a reference signal received power (Reference Signal Receiving Power, RSRP) and a received signal strength indication (Received Signal Strength Indication, RSSI). [0003] In the Long Term Evolution (Long Term Evolution, LTE or Long Term Evolution Advanced, LTE-A) system, when the bandwidth of the neighboring cell is different from the bandwidth of the serving cell, or there is interference from other systems in the bandwidth of the serving cell, if the middle six Resource block (Resource Block, RB), that is, on the middle 1.4MHz bandwidth, RSRQ measurement ...

[0003] In the Long Term Evolution (Long Term Evolution, LTE or Long Term Evolution Advanced, LTE-A) system, when the bandwidth of the neighboring cell is different from the bandwidth of the serving cell, or there is interference from other systems in the bandwidth of the serving cell, if the middle six Resource block (Resource Block, RB), that is, on the middle 1.4MHz bandwidth, RSRQ measurement will lead to low RSSI and high RSRQ, because the reference signal reception quality measured on the middle 6RB cannot represent the quality of the cell in some cases Signal reception quality, for example, the 6RB in the middle of the received signal receives relatively little interference and the bandwidth at both ends of the received signal receives relatively large interference
