Description

Method, device and terminal for identifying operator identification on unlicensed frequency bands

This application claims priority to Chinese Patent Application No. 201510344767.0, entitled "Methods, Devices and Terminals for Identifying Operator Identification on Unlicensed Frequency Bands", submitted to the Chinese Patent Office on June 19, 2015. The content is incorporated herein by reference.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for identifying an operator identifier on an unlicensed frequency band, an apparatus for identifying an operator identifier on an unlicensed frequency band, and a terminal.

Background technique

At present, with the rapid development of the mobile service, the capacity of the existing wireless spectrum allocated to the mobile service cannot meet the requirements. In the 3GPP Rel-13 phase, a mechanism called LAA (Licensed-Assisted Access) is introduced. In the LAA mechanism, the transmission of mobile communication can be carried on the unlicensed spectrum, such as the 5 GHz band. Currently, these unlicensed spectrums are mainly used by Wi-Fi, Bluetooth, radar, medical and other systems.

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 licensed spectrum is used to assist access on the unlicensed spectrum through a CA (Carrier Aggregation) mechanism. Currently, if LTE is used on the unlicensed spectrum, the system can work in the following two modes: one is SDL (Supplemental Downlink), that is, only downlink transmission subframes; the other is TDD (Time Division Duplex). Duplex mode, which includes both downlink subframes and uplink subframes.

In the scenario of traditional LTE network deployment, the terminal needs to know the cell ID of the serving cell for subsequent demodulation control. The terminal can obtain the cell ID of the serving cell by detecting a PSS (Primary Synchronization Signal) and an SSS (Secondary Synchronization Signal) broadcasted by the serving cell. Similarly, the terminal is detecting the RSRP (Reference Signal Receiving Power) of the neighboring cell or the RSRQ. (Reference Signal Receiving Quality), in the process of reporting, the result of RSRP or RSRQ is also reported to the serving cell together with the corresponding cell ID.

In addition, a fair de-shared resource is required on the unlicensed frequency band. Therefore, before occupying the channel resource, it is necessary to monitor the idleness of the channel resource before the resource can be occupied. After the resources are occupied, the terminal needs to perform RRM (Radio Resource Management) measurement of the serving cell and the neighboring cell. Since the working state of the cell on the unlicensed band is uncertain, measurement can be considered by DRS (Discovery Reference Signal) introduced in the 3GPP Rel-12 stage. The time-frequency position of the transmission of the DRS of the neighboring cell and the serving cell may be different.

In the case of the existing LTE network deployment, different operators will occupy different licensed frequency bands, and a certain licensed frequency band is allocated to an operator for independent use. Therefore, the operator can solve the neighboring cell through reasonable network deployment. The problem of cell ID conflicts between. On the unlicensed spectrum, since the frequency band may be shared by multiple operators, and the network deployment may not be coordinated among multiple operators, the cell ID between adjacent cells may be in conflict. In this case, it may cause confusion in the terminal when reporting the measurement results.

Therefore, how to accurately identify the cells of different operators on the unlicensed spectrum, and avoid the confusion caused by the cell ID collision when the terminal reports the measurement becomes a technical problem to be solved.

Summary of the invention

The present invention is based on at least one of the above technical problems, and proposes a new scheme for identifying an operator identifier on an unlicensed frequency band, which can ensure that the terminal accurately identifies a cell of a different operator in an unlicensed frequency band, and avoids the terminal.

The present invention also proposes a terminal (not shown) comprising: means 200 for identifying an operator identification on an unlicensed frequency band as shown in FIG.

The technical solution of the present invention will be described in detail below with reference to FIGS. 3A to 4.

The present invention mainly proposes a method for identifying a carrier identifier by a terminal applied to an unlicensed frequency band, which can effectively avoid the confusion caused by the collision of the cell ID when the terminal reports the measurement information. In response to this problem, the present invention mainly proposes three methods for solving the problem, and the following ones are explained:

method one:

It is identified by the signaling of DRS. Under this method, different operators can identify by different signaling design of DRS. The following is an example of the deployment scenario of two operators. The specific method can be:

The transmission format of the signaling transmitted in the DRS of the operator 1 and the operator 2 is differentiated. As shown in FIG. 3A, the transmission format of the signaling in the DRS of the operator 1 is shown in FIG. 3B, and the DRS in the operator 2 is shown in FIG. 3B. The transmission format of the signaling. The location of the PSS and SSS transmission in the DRS is different for the operator 1 and the operator 2, so the terminal can distinguish between the locations where the PSS and the SSS are detected.

However, the terminal needs the serving cell to notify the sequence of the DRS used by different operators, which can be through RRC signaling, MAC (Medium Access Control), CE (Control Element) or physical layer. Order to achieve. It should be noted by those skilled in the art that the transmission format of the DRS in one embodiment of the present invention is shown in FIG. 3A and FIG. 3B, in which the transmission position of the PSS and the SSS are different, and the specific implementation is implemented. It can also be distinguished by the transmission location of other signaling of the DRS.

Method Two:

It is identified by the configuration of the DRS that the configuration of the DRS between different operators may be different under this method. Take the scenario of two operators as an example:

As shown in Figure 4, different operators can allocate different DMTCs, such as configuring offset values of different DMTCs. In this case, assuming that different operators are synchronized based on GPS, the terminal can blindly check the location of the DRS transmission to learn the indications of different operators, or the serving base station notifies the terminal of the DRS of other operators. The location of the transmission so that the terminal performs a DRS search at the corresponding location to know if there are other operators' cells present. The serving base station needs to notify the terminal to search at the corresponding location through RRC signaling, MAC CE or physical layer signaling.

Method three:

The transmission of the initial signal indicates that it is necessary to introduce an initial signal for resource reservation and other functions before data transmission on the unlicensed band. Therefore, it is considered to introduce operation in the initial signal. Business instructions.

Specifically, it can be implemented by different operators using different sequences of initial signals. In this case, the sequence pools that need to be coordinated between different operators may be used. This coordination may be non- Often static, for example, two sequence pools can be pre-defined. Two different operators only occupy one of the sequence pools so that the sequences used by different operators are different, so that the terminal can detect the sequence of the initial signal. Values are learned to distinguish between different operators.

The technical solution of the foregoing embodiment of the present invention can effectively realize that two or more cells with the same cell ID can be correctly identified by the terminal during detection. Therefore, when performing measurement reporting, the base station can know whether the measured cell is in the end or not. The cell under this operator for subsequent operations.

As shown in FIG. 5, the terminal may include: at least one processor 51, such as a CPU, at least one communication bus 52 and a memory 53; a communication bus 52 for implementing connection communication between these components; and the memory 53 may be a high speed RAM The memory may also be a non-volatile memory such as at least one disk storage. A set of program codes is stored in the memory 53, and the processor 51 is configured to call the program code stored in the memory 53, and performs the following operations:

Detecting, by the different cells, an identification signal that is sent on an unlicensed frequency band that can identify the carrier to which the carrier belongs;

Determining an operator to which the identification signal belongs according to characteristics of the identification signal sent by the different cell.

Wherein the identification signal comprises a discovery reference signal;

The step of determining, by the processor 51, the operator to which the identification signal belongs according to the feature of the identification signal sent by the different cell, specifically includes:

Identifying a transmission format of the signaling in the discovery reference signal sent by the different cell;

Determining an operator to which the discovery reference signal belongs according to a transmission format of signaling in the discovery reference signal.

The processor 51 is further configured to perform the following operations before the step of determining the operator to which the discovery reference signal belongs according to the transmission format of the signaling in the discovery reference signal:

Receiving a sequence used by the different cell notified by the serving cell to send the discovery reference signal;

The step of determining, by the processor 51, the operator to which the discovery reference signal belongs according to the transmission format of the signaling in the discovery reference signal includes:

And comparing a transmission format of the signaling in the discovery reference signal with a sequence used by the different cell to send the discovery reference signal to determine an operator to which the discovery reference signal belongs.

Wherein the identification signal comprises a discovery reference signal;

Identifying a configuration format of the discovery reference signal sent by the different cell;

Determining an operator to which the discovery reference signal belongs according to a configuration format of the discovery reference signal sent by the different cell.

The processor 51 is further configured to perform the following operations:

Receiving, by the different cell notified by the serving cell, a time-frequency location of the discovery reference signal, to detect, by the first detecting unit, the discovery reference signal sent by the different cell at a corresponding time-frequency location; or

The discovery reference signal sent by the different cell is detected by means of blind detection.

Wherein the identification signal includes a start signal;

Detecting a sequence value of a start signal sent by the different cell;

Determining an operator to which the start signal belongs according to the detected sequence value of the start signal sent by the different cell.

The technical solution of the present invention is described in detail above with reference to the accompanying drawings. Considering that in the unlicensed spectrum, since the frequency band may be shared by multiple operators, and the network deployment may not be coordinated among multiple operators, it may be In the case where the cell ID between adjacent cells is a conflict, in this case, the terminal may be confused when reporting the measurement result. Therefore, the present invention proposes a new scheme for identifying an operator identifier on an unlicensed frequency band, which can ensure that the terminal accurately identifies a cell of a different operator in an unlicensed frequency band, and avoids the cell ID when the terminal reports the measurement information. Collisions lead to confusion.
