Description

Method and device for measuring radio resource management, terminal and base station

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for measuring radio resource management, a device for measuring radio resource management, a terminal, and a base station.

Background technique

At present, with the rapid development of mobile services, the capacity of the existing wireless spectrum allocated to the mobile service cannot meet the needs of users. Therefore, in the Rel-13 stage of 3GPP (The 3rd Generation Partnership Project), the LAA (Licensed Assisted Access) mechanism is introduced. In the LAA mechanism, the transmission of mobile communication can be carried on an unlicensed spectrum, such as the 5 GHz band. On these unlicensed spectrums, systems such as WIFI, Bluetooth, radar, and medical are currently in use.

Due to the diversity and complexity of the system on the unlicensed spectrum, the use of the LTE (Long Term Evolution) mechanism for the unlicensed spectrum cannot guarantee the security of the user and the stability of the connection. Therefore, in the mechanism of the LAA, the CA (Carrier Aggregation) mechanism can be used to implement access to the unlicensed spectrum by granting the spectrum. Currently, if LTE is used on the unlicensed spectrum, the system can work in two ways, as shown in Figure 1.

In the unlicensed spectrum, multiple systems need to compete to use resources. In order to ensure fair sharing between systems, a mechanism called “Let, Listen Before Talk” is introduced. That is to say, the system competing for the resource needs to monitor whether the channel is being occupied by another system before occupying the channel. If the channel is idle, then the system can take up the channel; if the channel is busy, then the system cannot occupy the channel. At present, there are two mechanisms for LBT, one is FBE (Frame based equipment) mechanism, and the other is LBE (Load based equipment) mechanism. In the case of the FBE mechanism, it is necessary to perform channel idle or not detection in a predetermined cycle, In the case of the LBE mechanism, the detection of channel idleness or not can be initiated at any time according to the needs of the service.

In addition, wireless resource management is very important for the terminal. Radio resource management includes measurement of RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), and RSSI (Reference Signal Strength Indicator). The base station can perform operations such as handover and reselection of the serving cell based on the result of the radio resource management. In the traditional radio resource management mechanism, the terminal can perform radio resource management measurement based on the restricted or unrestricted measurement resources, and the terminal reports based on the result of multiple detections.

However, on the unlicensed spectrum, the chance of occupying the channel cannot be determined, so the terminal may not be able to obtain multiple detection opportunities, and the result of multiple detections may result in inaccurate results due to long time intervals.

Therefore, how to improve the accuracy of the measurement points of a single radio resource management measurement by the terminal in unlicensed spectrum acquisition, so as to effectively perform single radio resource management measurement, thereby improving the reliability of measurement results and reducing energy consumption Solved technical problems.
