Description

Method and communication device for configuring secondary cell

Technical Field

The present application relates to the field of communications, and more particularly, to a communication apparatus for a method of configuring a secondary cell.

Background

Long Term Evolution (LTE) Licensed Assisted Access (LAA) technology is defined in the 3rd generation partnership project (3 GPP) Release 13(Release 13, R13) standard. The main idea of LAA is to aggregate one primary cell (PCell) and one or more secondary cells (scells) by using Carrier Aggregation (CA) technology. The main cell works in an authorized frequency band, and the auxiliary cell works in an unauthorized frequency band. The SCell operating in the unlicensed frequency band is also referred to as an LAA SCell or an unlicensed cell.

In the process of cell search, the network side needs to add an unlicensed cell for the terminal device. Since the network side does not know which unlicensed cells are near the location of the terminal device, the terminal device is required to perform measurement at a frequency point where the unlicensed cells may exist. In LAA, the unlicensed cell coverage is smaller than the primary cell coverage, and there may be multiple unlicensed cells within one primary cell. And the working frequency point of the authorization-free cell is automatically selected, the frequency point is not fixed, and more candidate frequency points are available. Therefore, under the condition that the measurement capability of the terminal equipment is far smaller than the total number of the frequency points of the unlicensed cell, the network side needs to adopt a method of sending the frequency points of the unlicensed cell in turn in batches to enable the terminal equipment to carry out measurement. For example, there are 12 total unlicensed cell frequency points in the coverage of the primary cell, the 12 frequency points are divided into ABC 3 groups before the network side sends the measurement configuration, each group of 4 frequency points sends 4 frequency points of group a first, and the terminal device continues to send frequency points of the second/third groups if it does not measure the corresponding unlicensed cell.

Based on the above method, any terminal device connected to the primary cell needs to perform the above polling measurement, which results in a long measurement time and low measurement efficiency.

Fig. 1 shows a schematic diagram of a communication system suitable for use in the present application. As shown in fig. 1, the system includes a network device 110 and a terminal device 120. The system may support LAA, for example, the system 100 is specifically LAA-LTE, or other communication systems, which is not limited in this application. When the network device 110 and the terminal device 120 communicate in the LAA manner, not only a licensed spectrum (licensed spectrum) but also an unlicensed spectrum (unlicensed spectrum) or an unlicensed spectrum may be used, where the unlicensed spectrum is integrated into a cellular communication network (e.g., LTE) originally using only a licensed spectrum in the LAA manner and may be used as a secondary component carrier in a carrier aggregation scenario. A carrier on the licensed spectrum is called a licensed carrier (licensed carrier), and a carrier on the unlicensed spectrum is called an unlicensed carrier or an unlicensed carrier (unlicensed carrier). The cell corresponding to the authorized carrier is a primary cell, and the cell corresponding to the unlicensed carrier is a secondary cell, which may be referred to as an unlicensed cell.

In the cell search process, the network device needs to add an unlicensed cell to the terminal device. Since the network device does not know which unlicensed cells are near the location of the terminal device, the terminal device is required to perform measurement at a frequency point where the unlicensed cells may exist. In LAA, the unlicensed cell coverage is smaller than the primary cell coverage, and there may be multiple unlicensed cells within one primary cell. And the working frequency point of the authorization-free cell is automatically selected, the frequency point is not fixed, and more candidate frequency points are available. Therefore, under the condition that the measurement capability of the terminal equipment is far smaller than the total number of the frequency points of the unlicensed cell, the network equipment needs to adopt a method of sending the frequency points of the unlicensed cell in turn in batches to enable the terminal equipment to carry out measurement.

For example, referring to the system shown in fig. 2, the coverage area of the main cell provided by the network device 110 includes 12 unlicensed cells or 12 unlicensed cell frequency points, because the network device 110 does not know the geographic location of the terminal device 120, the network device 110 divides the 12 frequency points into ABC 3 groups, each group of 4 frequency points transmits the 4 frequency points of the group a first, and the terminal device 110 continues to transmit the frequency points of the second group/the third group if the terminal device 110 does not measure the corresponding unlicensed cell. For other terminal devices in the primary cell, such as the terminal device 130, the network device 110 also makes the terminal device 130 perform polling measurement in the manner described above. Obviously, this method will result in a longer measurement time and a lower measurement efficiency for the terminal device.

In view of this, the present application provides a method for configuring a secondary cell, which is beneficial to reduce the measurement time of a terminal device and improve the measurement efficiency. Hereinafter, the method of the present application will be described in detail.

It should be understood that the network device in the present application corresponds to a primary cell, for example, the network device in the present application may be an LTE base station.

Before executing the method of the present application, the network device may establish a mapping relationship between the wireless fingerprint information and the unlicensed cell information based on a plurality of measurement reports reported by a plurality of terminal devices. The details will be described below.

(1) The network device determines a plurality of wireless fingerprint information based on the plurality of measurement reports.

Specifically, after receiving the measurement reports reported by the terminal devices, the network device may determine the wireless fingerprint information according to the measurement result of the primary cell, the measurement result of the co-frequency neighboring cell of the primary cell, and the cell identifier of the co-frequency neighboring cell in each measurement report.

In this application, the measurement result of the primary cell may include signal strength of the primary cell, such as RSRP, RSRQ, and the like. Similarly, the measurement result of the same-frequency neighboring cell may include signal strength of the same-frequency neighboring cell, such as RSRP, RSRQ, and the like. The wireless fingerprint information may include signal characteristics of the main cell, signal characteristics of the same-frequency neighboring cells, and cell identifiers of the same-frequency neighboring cells. The signal characteristic may be a strength of the signal, such as RSRP, RSRQ, etc. At least some of the plurality of terminal devices are located in different geographical locations of the primary cell, i.e. the measurement reports of the at least some terminal devices are different. Generally, the signal characteristics of the primary cell and/or the signal characteristics of the neighboring cells measured by the terminal devices at different geographical locations are different, and the geographical locations can be distinguished by using the difference of the signal characteristics.

For example, if the RSRP of the primary cell in one measurement report is-60 dBm, the RSRPs of the cells with the same frequency are: cell 1: -80dBm, Cell 2: -90dBm, the RSRP of the primary cell in another measurement report is-60 dBm, and the RSRPs of the co-frequency neighbor cells are respectively: cell 1: -81dBm, Cell 2: 90dBm, then the network device can get a wireless fingerprint from the two measurement reports: a primary cell: -60dBm, Cell 1: -80dBm, Cell 2: -90 dBm.

It should also be understood that each wireless fingerprint information may correspond to a virtual grid, that is, the network device may derive a plurality of virtual grids based on the plurality of measurement reports. How to obtain a plurality of virtual grids according to the plurality of measurement reports may specifically refer to the prior art, and details are not described here. However, it should be noted that the virtual grid in the prior art corresponds to an actual geographic location, while the virtual grid of the present application may not correspond to an actual geographic location, and the virtual grid of the present application may represent a difference in geographic location only by a difference in signal characteristics.

Illustratively, table 1 shows an example of a plurality of wireless fingerprint information. Each line of information except the first line in table 1 represents one wireless fingerprint information.

TABLE 1

(2) The network equipment determines the mapping relation between the wireless fingerprint information and the unauthorized cell information.

Specifically, the network device may determine a mapping relationship between the multiple pieces of wireless fingerprint information and the information of the unlicensed cell according to the measurement result of the unlicensed cell and the cell identifier of the unlicensed cell in each measurement report.

In this application, the information of the unlicensed cell may include a frequency point of the unlicensed cell.

Illustratively, table 2 shows a mapping relationship between a plurality of wireless fingerprint information and unlicensed cell information.

TABLE 2

It should be understood that the frequency point of the unlicensed Cell may also be used in table 2 to indicate the unlicensed Cell, for example, if the frequency point corresponding to Cell3 is F3, Cell3 may be replaced by F3.

The mapping relation between the wireless fingerprint information and the information of the authorization-free cell obtained based on the method can be used for predicting the authorization-free cell near any terminal equipment, so that the terminal equipment can be configured with a secondary cell.

Fig. 3 shows a schematic flow diagram of a method for configuring a secondary cell according to the present application. The method shown in fig. 3 will be explained below.

S310, the network equipment determines first wireless fingerprint information of the first terminal equipment.

The first terminal device may be any terminal device. The first wireless fingerprint information is wireless fingerprint information of the first terminal equipment.

In a possible implementation manner, the network device may determine the first wireless fingerprint information according to a common-frequency measurement report reported by the first terminal device. The same-frequency measurement report comprises a measurement result of the main cell, a measurement result of a same-frequency adjacent cell and a cell identifier of the same-frequency adjacent cell. More specifically, the network device may determine the first wireless fingerprint information according to a common-frequency measurement result reported by the first terminal device at a certain time or a measurement result reported within a certain period of time.

For example, in the common-frequency measurement result reported by the first terminal device at a certain time, the RSRP of the main cell is-63 dBm, and the RSRPs of the common-frequency neighboring cells are respectively: cell 1: -80dBm, Cell 2: 91dBm, then the network device may determine the first wireless fingerprint information as: a primary cell: -63dBm, Cell 1: -80dBm, Cell 2: -91dBm, or: a primary cell: -63dBm, Cell 1: -80dBm, Cell 2: -90 dBm.

For another example, when the network device determines the first wireless fingerprint information according to the measurement result reported by the first terminal device within a period of time, the network device may use an average value of RSRPs of the main cell within the period of time as the RSRP of the main cell, and correspondingly, the RSRPs of the same-frequency neighboring cells are respectively averaged and used as the RSRPs of the corresponding same-frequency neighboring cells.

S320, the network equipment determines wireless fingerprint information matched with the first wireless fingerprint information from a plurality of pieces of wireless fingerprint information stored in advance.

It is easy to understand that the wireless fingerprint information matched with the first wireless fingerprint information may be the wireless fingerprint information identical to the first wireless fingerprint information in the plurality of wireless fingerprint information, or the wireless fingerprint information whose difference from the first wireless fingerprint information is within a preset range in the plurality of wireless fingerprint information. For example, if the differences between the RSRP of the master Cell of the first wireless fingerprint information, the RSRP of the Cell1 of the same-frequency neighboring Cell, the RSRP of the Cell2 of the same-frequency neighboring Cell, the RSRP of the master Cell corresponding to the wireless fingerprint information #1 of the plurality of wireless fingerprint information, the RSRP of the Cell1 of the same-frequency neighboring Cell, and the RSRP of the Cell2 of the same-frequency neighboring Cell are all 2, it is determined that the wireless fingerprint information #1 matches the first wireless fingerprint information.

S330, the network device determines, according to the mapping relationship between the wireless fingerprint information and the unlicensed cell information, the unlicensed cell information corresponding to the wireless fingerprint information determined in S320.

Therefore, according to the method of the present application, the network device may determine, according to the wireless fingerprint information of any terminal device, the unlicensed cell information corresponding to the terminal device by pre-establishing a mapping relationship between the wireless fingerprint information and the unlicensed cell information, that is, the network device may determine the unlicensed cell near the terminal device. Therefore, the network equipment does not need to send all the authorization-free cell frequency points in the coverage area of the network equipment to the terminal equipment for measurement, the signaling overhead is reduced, and the measurement efficiency of the terminal equipment is improved.

Optionally, after S330, the method may further include:

s340, the network device configures the auxiliary cell to the first terminal device according to the determined information of the authorization-free cell.

In a possible implementation manner, the network device may send, to the first terminal device, a frequency point corresponding to the determined authorization-free cell according to the determined authorization-free cell information; and the terminal equipment measures the cell corresponding to the frequency point and then sends the obtained pilot frequency measurement report to the network equipment. The network device may configure the secondary cell for the first terminal device according to the inter-frequency measurement report. For example, the network device may configure, as the secondary cell of the first terminal device, the unlicensed cell with the largest cell signal strength, such as RSRP, in the inter-frequency measurement report.

In addition, if the information of the unlicensed cell determined in S330 is only one unlicensed cell or only includes one frequency point, the network device may directly configure the cell or the cell corresponding to the frequency point as the secondary cell of the first terminal device, without the need for the first terminal device to perform measurement.

It should be understood that, in the foregoing embodiments, the sequence numbers of the processes do not imply an execution sequence, and the execution sequence of the processes should be determined by functions and internal logic of the processes, and should not constitute any limitation to the implementation process of the embodiments of the present application.
