Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of a wireless communication system according to an embodiment of the present application. The wireless communication system provided in this embodiment includes a UE 101 and a network device 102 .

Optionally, UE101 may refer to various forms of user equipment, access terminals, subscriber units, subscriber stations, mobile stations, mobile stations (mobile stations, MS for short), remote stations, remote terminals, mobile equipment, terminal equipment ( terminal equipment), wireless communication equipment, user agent or user equipment.

Optionally, the network device 102 is a public mobile communication network device, which is an interface device for the UE 101 to access the Internet, and is also a form of a radio station. A radio transceiver station, including a Base Station (BS for short), also known as base station equipment, is a device deployed in a Radio Access Network (RAN) to provide wireless communication functions.

Wireless communication networks have many application scenarios, such as macrocells with wide coverage and a large number of users, microcells with small coverage and few users, and picocells with smaller coverages Wait.

Among them, many cell parameters of the wireless communication network, such as Cell-RadioNetworkTemporaryIdentifier (C-RNTI for short), MAC CE, Backoff Indicator (BI for short), etc., are related to the coverage of the cell, cell users numbers are related.

However, at present, when determining how much bit width to use for cell parameters, it is determined with reference to the coverage of the macro cell and the number of users. In other words, there will be some redundancy in the corresponding cell parameters. For example, the C-RNTI of LTE and NR are both 16 bits, and the maximum number of users in the corresponding cell is 65536. This maximum value applies to macro cells, but the maximum number of users in micro cells or pico cells is usually much lower than this maximum value. Therefore, if the C-RNTI of the micro cell or the pico cell is still represented by 16 bits, there will be more bit redundancy, resulting in a low utilization rate of wireless spectrum resources.

In order to solve the above technical problems, the embodiments of the present application provide a method for determining cell parameters. The network device and the UE can determine the cell parameter bit width of the cell according to the cell type of the cell, and then determine the cell parameter bit width of the cell according to the cell type. The determined cell parameter bit width is used to determine the cell parameter of the cell, wherein the cell parameter bit widths corresponding to different types of cells are different. That is, for a cell with a small coverage and a small number of users, such as a micro cell or a pico cell, a smaller bit width can be used to represent its cell parameters, reducing the redundancy in its cell parameters, thereby reducing the wireless spectrum resource overhead of signaling. , to improve the utilization of wireless spectrum resources. Please refer to the following examples of this application for details:

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a method for determining a cell parameter provided by an embodiment of the present application, and the execution body of this embodiment is the UE in the embodiment shown in FIG. 1 . As shown in Figure 2, the method includes:

S201. Receive the cell type of the cell where the UE is currently located and sent by the network device.

In a feasible implementation manner, the network device may determine the cell type of the current cell according to the cell coverage and/or the number of users of the current cell. And after the cell type of the current cell is determined, the cell type of the current cell is sent to the UE.

S202. Determine the target cell parameter bit width of the cell where the UE is currently located according to the cell type of the cell where the UE is currently located, wherein the cell parameter bit widths corresponding to different cell types are different.

In a feasible implementation manner, the UE may acquire the pre-configured correspondence between the cell type and the cell parameter bit width, and then determine the target cell of the cell where the UE is currently located according to the cell type of the cell where the UE is currently located and the above-mentioned correspondence Parameter bit width.

Exemplarily, it is assumed that the pre-configured cell parameter bit width for type A cells is 16 bits, the pre-configured cell parameter bit width for type B cells is 8 bits, and the pre-configured cell parameter bit width for type C cells is 4 bits, Then, when the cell type of the cell where the UE is currently located is type A, the bit width of the target cell parameter of the cell where the UE is currently located is determined to be 16 bits; when the cell type of the cell where the UE is currently located is type B, the target cell of the cell where the UE is currently located is determined. The parameter bit width is 8 bits; when the cell type of the cell where the UE is currently located is type C, it is determined that the target cell parameter bit width of the cell where the UE is currently located is 4 bits.

S203: Determine the cell parameters of the cell where the UE is currently located according to the parameter configuration information of the cell where the UE is currently located and the above-mentioned parameter bit width of the target cell.

In the embodiment of the present application, after determining the target cell parameter bit width of the cell where the UE is currently located, the cell parameters of the cell where the UE is currently located may be determined according to the parameter configuration information of the cell where the UE is currently located. For example, assuming that the value of a certain cell parameter of the cell where the UE is currently located is configured as "3", then when the target cell parameter bit width of the cell is 4 bits, the cell parameter is determined to be "0011"; When the target cell parameter bit width is 8 bits, the cell parameter is determined to be "00000011"; when the target cell parameter bit width of the cell is 16 bits, the cell parameter is determined to be "00000000000000011".

It can be understood that since the UE needs to carry the cell parameters of the cell when performing signaling interaction with the network device, reducing the bit width of the cell parameters can effectively reduce the wireless spectrum resource overhead of signaling, thereby improving the wireless spectrum. resource utilization.

In the method for determining cell parameters provided by the embodiments of the present application, the UE may determine the cell parameter bit width of the cell according to the cell type of the cell, and then determine the cell parameter of the cell according to the parameter configuration information of the cell and the determined cell parameter bit width. , that is, the cell parameters corresponding to different types of cells can use different bit widths, so for cells with small coverage and small number of users, such as micro cells or pico cells, a smaller bit width can be used to represent their cell parameters, reducing the Redundancy in cell parameters reduces signaling overhead of wireless spectrum resources and improves utilization of wireless spectrum resources.

Based on the content described in the above embodiment, in a feasible implementation manner of the present application, after determining the cell type of the current cell, the network device may add the cell type indication information of the current cell to the system message, and broadcast the system information.

The UE monitors the system message broadcast by the network device, and can obtain the cell type of the cell where the UE is currently located by parsing the cell type indication information in the received system message.

Optionally, the above cell types may include macro cells, micro cells, and pico cells, wherein, in this embodiment of the present application, the values of the cell parameter bit widths corresponding to the macro cells, micro cells, and pico cells decrease sequentially.

Exemplarily, in the LTE and NR systems, the bit width of the C-RNTI is 16 bits, and the maximum number of users in the corresponding cell is 65536. This maximum value is applicable to the macro cell, and because the number of users in the micro cell or pico cell is far Much lower than this maximum value, therefore, for micro or pico cells, fewer bits can be used to represent the C-RNTI.

Exemplarily, in the NR system, the TA value of the MAC CE is 6 bits, and the value range of the TA is related to the cell radius. The larger the cell radius, the larger the TA range that needs to be supported. The smaller the TA range supported. That is, for a micro cell or a pico cell, the TA can also be represented by a smaller number of bits.

Exemplarily, the Backoff Indicator (BI for short) is used to indicate the congestion state of the cell. If a large number of users need to access the network at the same time, the network needs to indicate a larger backoff parameter. The UE receives the BI and checks the table to determine the fallback time for subsequent accesses. The number of users in a macro cell may vary within a large range, and more BI needs to be supported, while for a micro cell or pico cell, the number of users fluctuates in a small range, and the network congestion may be completely different from that of a macro cell. The scope can also be completely different, so less BI is needed to meet the needs. That is, for a micro cell or a pico cell, the BI can also be represented by a smaller number of bits.

Exemplarily, when the UE in the IDLE state competes for access, the MSG3 contains the UE-Identity, and the subsequent network sends the Contention Resolution Identity. If it can successfully match the UE-identity of MSG3, then Completion of competition resolution. In the LTE and NR systems, the contention resolution identifier is ⁴⁸ bits, which means that at most 248 IDLE UEs that may access the network can be identified. Considering the micro cell or pico cell, the number of users may be much lower than this number, so fewer IDLE UEs can be used. bit to represent the contention resolution flag.

It can be understood that the above are just a few examples, the purpose is to illustrate that some cell parameters corresponding to different types of cells can use different bit widths. In addition to some parameters listed above, there should be more similar cell parameters. The bit width thereof may also be determined according to the cell type of the cell, which is not repeated in this embodiment of the present application.

S301. Determine the cell type of the current cell.

In a feasible implementation manner, the network device may determine the cell type of the current cell according to the cell coverage and/or the number of users of the current cell.
