Background
In the initial stage of mobile communication network construction, all cells are equal in size and same in capacity, and with the increase of city construction and the number of users, the user density is not equal any more. In order to adapt to the situation, in a high-user-density area, the area of a cell is divided into small areas, or the omni-directional coverage of a base station in the cell is changed into directional coverage, so that the number of channels allocated to each cell is increased, and the requirement of increasing the traffic volume is met. In the prior art, in a cell splitting manner, different splitting cells are usually distinguished by Carrier Aggregation (CA) configuration on different antennas, the splitting cells are configured based on the number of cells that can be supported by a current frequency band, and each splitting cell needs to occupy a whole set of independent intermediate frequency signal resources, where an intermediate frequency signal is a signal form of an intermediate frequency, the intermediate frequency is relative to a baseband signal and a radio frequency signal, and the intermediate frequency may have one or more stages and is a bridge for transition between the baseband signal and the radio frequency signal.
When intermediate frequency resources are allocated at a Radio Remote Unit (RRU) side, a common cell or a split cell is not distinguished, and processing is performed uniformly according to the common cell. The RRU corresponds to the intermediate frequency channel through the cell carrier number, each split cell is treated as an independent common cell, and each split cell occupies a whole set of independent intermediate frequency resources, resulting in waste of intermediate frequency resources. And because the number of the split cells supported by the RRU is limited by the number of the common cells that the RRU can support, the frequency band resource of the RRU cannot be fully utilized, and the RRU cannot adapt to complex application scenarios such as an external field.

Thus, the appearances of the phrase "in an embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
Fig. 1 shows a flowchart of an intermediate frequency resource allocation method according to an embodiment of the present invention.
As shown in fig. 1, the method for configuring intermediate frequency resources provided in the embodiment of the present invention specifically includes the following steps:
The target cell may be a normal cell or a split cell. The intermediate frequency resources used by the two paired split cells and the corresponding common cell are the same, so that the two paired split cells can be merged to the same intermediate frequency channel for processing, the intermediate frequency resources are saved, and the split cells are expanded.
The preset operation instruction may be an activation operation instruction or a deactivation operation instruction.
When a preset operation instruction is received, firstly, determining a target carrier number of a target cell; the carrier number is the carrier number allocated when the cell is established. The corresponding relation between the carrier numbers and the central frequency points is recorded in a preset carrier table; and after the target carrier number is determined, searching a target central frequency point corresponding to the target carrier number according to a preset carrier table.
As a first example, the form of the preset carrier table may be as shown in fig. 2, where, taking RRU devices of 8 radio frequency channels as an example, fig. 2 records all cell information on 8 radio frequency channels, and each channel has at most 24 carriers; optionally, the preset carrier table may further record parameter information such as an effective carrier, a center frequency point and a radio frequency channel corresponding to the carrier, a cell bandwidth, and a cell power.
For a common cell, the carrier number, the center frequency point and the intermediate frequency channel number have a one-to-one correspondence relationship, and each carrier fixedly corresponds to 4 radio frequency channels, so that the intermediate frequency channel number can be directly indexed by the carrier number, and the implementation is also simpler, for example, if the target carrier number of the target cell is 2, the corresponding center frequency point number is 2, and the intermediate frequency channel number is 2.
For a pair of split cells, in the splitting process, the original carrier numbers are the same, but the selected center frequency points may not be the same, for example, for the split cells a and B, the radio frequency channel of the cell a is (1, 3), and the radio frequency channel of the cell B is (2, 4); in the splitting process, the cell A, B may select one carrier number from the carrier numbers 1-3, so that the carrier numbers finally selected by the two may not be consistent, resulting in inconsistent center frequency points finally selected.
Therefore, if the processing is performed according to the flow of the common cell, the finally selected center frequency points of the two split cells may be inconsistent, and the two split cells respectively select different intermediate frequency channels. Therefore, the intermediate frequency channel number cannot be indexed only by the carrier number, and the center frequency point number needs to be determined according to the carrier number and then indexed by the center frequency points on different radio frequency channels.
The RRU device is further provided with a preset intermediate frequency resource table (i.e., the intermediate frequency table shown in fig. 2), where the preset intermediate frequency resource table records a corresponding relationship from a central frequency point to an intermediate frequency channel; and the two carrier numbers respectively used as a pair of split cells have the same corresponding central frequency point.
For a pair of split cells, although the numbers of the radio frequency channels are different, the same central frequency point is respectively used, and the central frequency point and the intermediate frequency channel have a one-to-one correspondence relationship, so that after the central frequency point is determined, a target intermediate frequency channel corresponding to the target central frequency point can be determined according to a preset intermediate frequency resource table.
As a second example, referring to fig. 3, fig. 3 shows a form of a preset intermediate frequency resource table. Fig. 3 records the correspondence between the center frequency point of the established cell and the intermediate frequency channel number. Taking an activation operation as an example, when a cell is activated, all intermediate frequency information of a Field-Programmable Gate Array (FPGA), including parameters such as CA, bandwidth, and compression mode, needs to be configured, and when the parameters are configured, a preset intermediate frequency resource table needs to be searched, a channel number of a corresponding target intermediate frequency channel is obtained, and then configuration is performed.
For example, a pair of split cells a and B, the radio frequency channel of cell a is 1 or 3, and the radio frequency channel of cell B is 2 or 4; determining a target central frequency point corresponding to the target carrier number according to a preset carrier table, and locking the target central frequency point; and determining a target intermediate frequency channel according to the target central frequency point.
The preset intermediate frequency table is updated synchronously with the carrier table, and the basic function of the two tables is to combine two split cells with the same frequency point and different radio frequency channels into one intermediate frequency channel for processing.
And 103, configuring the target intermediate frequency channel according to the preset operation instruction.
After a target intermediate frequency channel is determined, configuring the target intermediate frequency channel according to a preset operation instruction; if the preset operation instruction is activation operation, configuring the target intermediate frequency channel for the target cell; and if the preset operation instruction is the deactivation operation, deactivating the target cell.
As a third example, fig. 4 shows the entire intermediate frequency resource configuration process of a split cell. Still taking RRU devices of 8 radio frequency channels as an example, the carrier table in fig. 4 is the preset carrier table shown, and the intermediate frequency table is the intermediate frequency resource table.
Taking the splitting cell 1 and the splitting cell 2 as an example, the corresponding center frequency points of the two cells are the same, and finally the two cells are combined to the same intermediate frequency channel (i.e. the intermediate frequency 1) for processing, so that each pair of splitting cells are processed in this way, and more intermediate frequency resources can be saved. Because four radio frequency channels of different frequency bands can be combined to 4 antenna ports through the antenna filter, the antenna ports [1 and 3] are linked by the same group of phase shifters, but the polarization is opposite, two orthogonal wave beams can be generated, and the same group of antennas is designed. The antenna ports [2, 4] are linked by another set of phase shifters, but with opposite polarization, can produce two orthogonal beams, designed as another set of antennas. Correspondingly, in the cell distribution, two split cells with the same frequency point need to be distributed to the radio frequency channels [1, 3] or [5, 7] according to the frequency band, and distributed to the radio frequency channels [2, 4] or [6, 8] by one.
The embodiment of the invention is preferably applied to RRU equipment, such as RRU equipment with 8 radio frequency channels, which is installed on a street lamp post of a main road in a city, wireless signals need to cover the road surface and an opposite high building at the same time, and six LTE (long term evolution) cells with 4T4R (a base station has 4 transmitting antennas and 4 receiving antennas) can be established at the same time. In order to accommodate more users, provide system capacity, and meet bursty traffic demands, directional coverage needs to be supported in beam configuration, that is, one 4T4R cell is split into two 2T2R cells, one 2T2R cell covers the road surface, and the other 2T2R cell covers the opposite tall building.
Six intermediate frequency channels are provided by an FPGA of the device, each intermediate frequency channel is processed according to 4T4R, six common cells can be simultaneously supported in distribution, the processing limit of the FPGA has been reached in the design of the existing RRU, in order to save resources and reduce the design complexity, the TRX is also processed according to 4T4R, if 2T2R is required to be supported, except that the resources of the FPGA and a Transceiver (TRX) are increased, no expansion space exists in hardware, the occupation ratio of the FPGA and the TRX in the hardware cost of the RRU is higher, and the cost performance of the RRU is reduced by increasing the two resources.
In the above embodiment of the present invention, when a preset operation instruction for a target cell is received, a target center frequency point corresponding to the target carrier number is determined according to the target carrier number of the target cell and a preset carrier table of a radio remote unit RRU to which the target cell belongs; acquiring a preset intermediate frequency resource table of the RRU, and determining a target intermediate frequency channel corresponding to the target central frequency point according to the preset intermediate frequency resource table; according to the preset operation instruction, the target intermediate frequency channel is configured, so that two paired split cells are merged to the same path of intermediate frequency channel for processing, intermediate frequency resources are saved, and the split cells are expanded; on the premise of keeping the existing TRX and FPGA processing architecture unchanged, by utilizing the characteristics of the same frequency point and the same bandwidth of the split cell and through the preset carrier table and the preset intermediate frequency resource table, intermediate frequency resources are fully utilized, the TRX configuration and FPGA intermediate frequency channel processing complexity is reduced, and the capacity of the RRU equipment for supporting the split cell is improved.
