For terminal equipment, the chip size can be reduced and the economic cost can be reduced.

It can be understood that the schematic structural diagram of the terminal device provided in the embodiment of FIG. 1 is to more clearly describe the technical solutions of the embodiments of the present invention, and does not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Personnel know that, with the evolution of the terminal device structure and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

Referring to FIG. 1 , please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a radio frequency module allocation method according to an embodiment of the present invention. Allocating the radio frequency module between the first baseband module and the second baseband module includes but is not limited to the following steps S210-S220:

Step S210: Obtain a request for use of the target operating frequency band by the first baseband module or the second baseband module, where the target operating frequency band is a working frequency band jointly supported by the first baseband module and the second baseband module.

For example, taking the terminal device as a mobile phone as an example, the mobile phone includes a WIFI baseband module or a Modem baseband module, if the first baseband module is a WIFI baseband module and the second baseband module is a Modem baseband module. Among them, the WIFI baseband module can scan the surrounding environment of the mobile phone for wireless access points (Access Point, AP) within a preset period, and the Modem baseband module can make the mobile phone communicate with the base station in the environment where the mobile phone is located. , in order to realize the data network service of the mobile phone. Then, the terminal device obtains the request for the use of the target working frequency band by the first baseband module or the second baseband module, that is, the mobile phone obtains the request for the use of the target working frequency band by the WIFI baseband module or the Modem baseband module, wherein the target working frequency band is the WIFI baseband The working frequency band jointly supported by the module and the Moden baseband module, specifically the working frequency band of 2.4GHz or 5GHz.

Step S220: Allocate the radio frequency module to the first baseband module or the second baseband module based at least on at least one of the following information: whether the target operating frequency band is being used by the first baseband module or the second baseband module, whether it is being used by the first baseband module The module uses the RF module, the request priority of the baseband module that requests the target operating frequency band.

In a possible implementation manner, when the target operating frequency band is not used by the first baseband module or the second baseband module, the radio frequency module is allocated to the baseband module requesting the target operating frequency band.

For example, the terminal device is a mobile phone as an example for illustration, and the mobile phone includes a WIFI baseband module and a Modem baseband module. After the mobile phone obtains the request for using the target working frequency band from the WIFI baseband module or the Modem baseband module, the mobile phone determines whether the target working frequency band (ie, the WIFI band) is used. If the WIFI band is not used, the mobile phone can receive the use request regardless of whether the sender of the use request is the WIFI baseband module or the Modem baseband module. Further, the mobile phone determines the sending end that sends the usage request, wherein the sending end of the usage request is a WIFI baseband module or a Modem baseband module.

In a possible implementation manner, when the target operating frequency band is being used by the first baseband module or the second baseband module, according to whether the baseband module using the target operating frequency band is the first baseband module or the second baseband module, Assign RF modules.

For example, when the mobile phone determines that the WIFI band is being used, it further determines whether the baseband module that is using the WIFI band is a WIFI baseband module or a Modem baseband module. If the WIFI baseband module is using the WIFI band, it means that the mobile phone can download or upload data through the WIFI network service, and there is no need to download or upload data through the LAA function of the Modem baseband module. Therefore, the mobile phone deletes the use request and still assigns the radio frequency module to the WIFI baseband module.

In a possible implementation manner, when the baseband module using the target working frequency band is the second baseband module, obtain the request priority of the first baseband module requesting the target working frequency band, and allocate the radio frequency module according to the request priority .

For example, if the Modem baseband module is using the WIFI band, it can determine the use request for the WIFI band sent by the WIFI baseband module, obtain the request priority of the WIFI baseband module requesting the WIFI band, and allocate the RF module according to the request priority. . Specifically, the WIFI baseband module can periodically detect the APs around the mobile phone. If a request sent by the WIFI baseband module is received at a certain time, it is considered that the request priority of the WIFI baseband module is higher than that of the Modem baseband module, and the radio frequency module is assigned to WIFI baseband module; if the request sent by the WIFI baseband module is received within a certain period of time, it is considered that the request priority of the WIFI baseband module is lower than that of the Modem baseband module, and the radio frequency module is still allocated to the Modem baseband module.

Through the radio frequency module allocation method provided by the embodiment of the present invention, based on the LAA protocol, it is proposed that the Modem baseband module can share the working frequency band supported by the WIFI baseband module, and the WIFI baseband module can share the radio frequency module of the Modem baseband module, that is, the WIFI baseband module can be realized. The module and the Modem baseband module can share the same RF module. For terminal equipment, the chip size can be reduced and the economic cost can be reduced.

In addition, since the WIFI standard uses Orthogonal Frequency Division Multiplexing (OFDM) technology and Multiple Input Multiple Output (MIMO) technology, the LTE/NR standard in the 3GPP protocol also uses Orthogonal Frequency Division (OFDM) technology. Multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) technology and Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) technology, so on the basis of Figure 1, the WIFI baseband module and the Modem baseband module can share a baseband module.

The structure diagram of the terminal device 300 includes: a frequency band arbitration module 301 , a baseband hardware module 302 , a radio frequency module 303 and a power management module 304 . The baseband hardware module 302 supports hardware of the first baseband (WIFI baseband) and the second baseband (Modem baseband). The baseband hardware module 302 is connected to the frequency band arbitration module 301 , which is also connected to the radio frequency module 303 . In addition, the first baseband (WIFI baseband) and the second baseband (Modem baseband) are implemented at the protocol level through the first baseband software and the second baseband software, thereby enabling the first baseband and the second baseband to share the baseband hardware, further reducing Chip size, reduce economic cost.

In a possible implementation manner, after obtaining the use request for the target working frequency band, it is determined whether the target working frequency band is used, and if the target working frequency band is not used, the baseband hardware module 302 of the use request is authorized, so that the baseband The hardware module 302 schedules the target working frequency band through the radio frequency module 303 .

In a possible implementation manner, when the target operating frequency band is being used by the first baseband or the second baseband, the radio frequency is allocated according to whether the baseband module using the target operating frequency band is supported by the first baseband or the second baseband Module 303. Specifically, if the baseband module using the target working frequency band is supported by the first baseband, the radio frequency module 303 is still allocated to the first baseband; if the baseband module using the target working frequency band is supported by the second baseband Then, the baseband module requesting the target working frequency band is supported by the first baseband, and the request priority of the first baseband requesting the target working frequency band is obtained, and the radio frequency module 303 is allocated according to the request priority.
