Detailed ways

At present, in the semi-static spectrum sharing scheme of 4G system and 5G system, if based on the PRB utilization information exchanged between the 4G system and the 5G system, it is determined that the 5G system will use the shared frequency band resources in the next cycle, and the 4G users in this frequency band must be used. Migrate to other non-shared 4G system frequency bands. At the same time, in order to avoid the interference of the cell reference signal (CRS) of the 4G system on the 5G service channel, the 4G cell needs to be shut down (deactivated). If it is determined that the 4G system uses the frequency band resource in the next cycle, the 4G cell needs to be reactivated.

Compared with dynamic, the semi-static decision time is on the second level, but frequent activation and deactivation of 4G cells will not only affect the hardware performance of the device, but also bring complexity to the operation and maintenance of the network.

In order to solve the above problems, the embodiments of the present application provide a spectrum resource sharing solution, which can solve the problem of turning off and turning on (activating and deactivating) 4G cells when the 4G system and the 5G system perform semi-static carrier-level spectrum sharing.

It should be understood that the terms “first”, “second”, etc. in the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, for example, it can be implemented in a sequence other than those given in the illustration or description of the embodiments of the present application.

Refer to FIG. 1, which is a schematic flowchart of a spectrum resource sharing method provided by an embodiment of this application. As shown in the figure, the network equipment executes the following process according to this static spectrum sharing period:

S101: In the current cycle, determine whether the shared spectrum resource is used by the 5G system in the next cycle, if yes, go to S102, otherwise end this process.

In this step, the network equipment can determine whether the 5G system uses the shared spectrum resource or the 4G system uses the shared spectrum resource in the next cycle according to the PRB utilization rate of the cell resource usage.

S102: Determine whether the shared spectrum resource is used by the 4G system in the current cycle, if yes, go to S103, otherwise end this process.

S103: Set the 4G cell as an access bar (cell bar), and proceed to S104.

Among them, setting the 4G cell as an access bar (cell bar) can prohibit new users from accessing the 4G cell.

S104: According to the configuration of the Cell-specific Reference Signal (CRS) of the 4G system, it is the non-zero power Channel state information reference signal (non-zero power Channel state information-Reference) that is not configured for spectrum sharing in the 5G system. Signal, ZP-CSI-RS) resources are configured by users of ZP-CSI-RS resources for spectrum sharing.

Optionally, when it is determined that the 5G system uses the shared spectrum resource in the next cycle, and the 4G system uses the shared spectrum resource in the current cycle, the network device also migrates users of the 4G cell to other non-shared 4G frequency bands.

Optionally, if according to the semi-static spectrum sharing period, it is determined in the current period that the shared spectrum resource is used by the 4G system in the next period, and the shared spectrum resource is used by the 5G system in the current period, the 4G cell access barring can be cancelled.

The sequence of steps in the above process is only an example. In some other embodiments, step S102 and step S103 can also be executed in an exchange order or in parallel. In other embodiments, step S103 and step S104 can also be executed in an exchange order. Or execute in parallel.

It should be noted that the 4G system and the 5G system share spectrum resources in the embodiment of this application as an example. According to the principle of this application, the embodiment of this application can be applied to two other types or versions of wireless communication systems that need to share spectrum. The application scenario of the resource.

In the above-mentioned embodiment of the application, according to the semi-static spectrum sharing period, it is determined in the current period that the 5G system uses the shared spectrum resource in the next period, and the 4G system uses the shared spectrum resource in the current period, then the 4G system cell is set In order to prohibit access, and according to the CRS of the 4G system, users in the 5G system who are not configured with ZP-CSI-RS resources for spectrum sharing are configured with ZP-CSI-RS resources for spectrum sharing, but the second radio is not configured. The cell of the communication system is deactivated, so that different wireless communication systems share the use of spectrum resources and solve the problem of resource coordination and mutual interference. Since frequent activation and deactivation of 4G cells are avoided, the embodiments of the present application not only reduce the impact on the hardware performance of the device, but also reduce the complexity of network operation and maintenance.

CSI-RS is a kind of 5G downlink reference signal, including non-zero power CSI-RS (NZP CSI-RS) and zero power CSI-RS (zero power Channel state information-Reference Signal, ZP CSI-RS). Among them, NZP CSI-RS is mainly used for channel state information (Channel state information, CSI) feedback, mobility management, Layer 1 Reference Signal Received Power (Layer 1 Reference Signal Received Power, L1-RSRP) measurement and tracking pilot (Trace Reference Signal, TRS) time-frequency tracking, etc.; ZP CSI-RS is mainly used for rate matching (RM) of the physical downlink shared channel (Physical downlink shared channel, PDSCH).

The embodiments of this application can configure ZP CSI-RS resources for users to perform rate matching based on the method defined by 3GPP 38.331, and the configuration of CSI-RS can distinguish PRBs and symbols.

Taking the LTE system as an example, the 2-port (2port) CRS distribution is shown in Figure 2. As shown in Figure 2, each square represents a resource element (Resource Element, RE), _{the square marked "R 0} "is the RE mapped to CRS port 0, and _{the square marked "R 1} " is CRS The RE to which port 1 is mapped.

For a 5G cell, taking 30kHZ as an example, 1 symbol (symbol) of 4G is equivalent to 2 symbols (symbol) of 5G. Considering the 2-port LTE CRS scenario, configuring a single-port CSI-RS for 5G users is not enough to cover all CRS positions, so a 4-port CSI-RS pattern can be used, as shown in Figure 3. Wherein, each square represents an RE, and the dashed box in the figure exemplarily shows the RE to which a group of 4-port CSI-RS is mapped.

It should be noted that the above configuration only needs to be configured within the spectrum shared bandwidth, and the non-spectrum shared bandwidth does not need to be configured. This principle can be implemented through the PRB configuration in the RateMatchPattern parameter. In addition, if the number of LTE CRS ports is configured in other ways, it can be configured according to the principle of the above solution.

Optionally. In the embodiment of this application, in order to avoid the terminal reconfiguration signaling storm caused by the spectrum sharing decision of the 4G system and the 5G system, considering the semi-static sharing nature, it can be determined when the user initially accesses if there are 4G and 5G If the spectrum resource is shared, and the semi-static spectrum sharing function is turned on, the ZP-CSI-RS resource for spectrum sharing is configured for the user during initial access.
