In this embodiment, the terminal 100 includes a first baseband processor 110, a second baseband processor 120, a first radio frequency chip 130, a second radio frequency chip 140, a first antenna 151, a second antenna 152, and a third antenna 153. The four antennas 154, the first card slot 160 connected to the first baseband processor 110, and the second card slot 170 connected to the second baseband processor 120. The first card slot 160 and the second card slot 170 are both used for placing a SIM card. The first baseband processor 110, the second baseband processor 120, the first radio frequency chip 130, and the second radio frequency chip 140 all support the third generation or higher mobile communication technology access capability.

Advanced International Mobile Communications) technology.

The first baseband processor 110 is connected to the first antenna 151 through the first radio frequency chip 130. The first baseband processor 110 is connected to the second antenna 152 through the first radio frequency chip 130, and the second baseband processor 120 passes the second radio frequency. The chip 140 is connected to the third antenna 153, and the second baseband processor 120 is connected to the fourth antenna 154 through the second RF chip 140;

The first RF chip 130 is connected to the first antenna 151 to form a first path; the first RF chip 130 is connected to the second antenna 152 to form a second path; the second RF chip 140 is connected to the third antenna 153 to form a third path; The radio frequency chip 140 is connected to the fourth antenna 154 to form a fourth path.

The first path, the second path, the third path, and the fourth path are used to transmit data between the terminal 100 and an external device. The external device may be various devices on the network side, such as a base station, or other terminals.

The first baseband processor 110 can be selectively connected to the third path or the fourth path. For example, a switch 180 may be disposed between the first baseband processor 110 and the second radio frequency chip 140. By controlling the switch 180, the first baseband processor may be connected or disconnected from the third path or the fourth path. Specifically, as shown in FIG. 1 , the first baseband processor 110 can be connected to the second radio frequency chip 140 through the switch 180 . When the first baseband processor 110 needs to transmit data through the third path, the control switch 180 turns on the connection between the third path and the third path.

It should be noted that the switch 180 may be a switch having a function of connecting or disconnecting a plurality of paths; or, the switch 180 may be a plurality of switches, and one switch is respectively disposed in each path.

In an embodiment of the present embodiment, the first antenna 151 and the third antenna 153 may be a main set antenna for transmitting uplink data and downlink data, and correspondingly, the first path and the third path are also used for transmission. Uplink data and downlink data; the second antenna 152 and the fourth antenna 154 may be diversity antennas for transmitting downlink data, and correspondingly, the second path and the fourth path are also used for transmitting downlink data. It is to be understood that the above-mentioned antennas are not limited to the above-mentioned types, that is, in other embodiments, the antennas may be set to antennas of corresponding types according to actual requirements, for example, the antennas are antennas capable of transmitting uplink data and downlink data, or One antenna and the third antenna are antennas that can transmit uplink data, and the second antenna and the fourth antenna are antennas that can transmit downlink data. The uplink data refers to data sent by the terminal to the network side, and the downlink data refers to data sent by the network side to the terminal.

Based on the terminal structure, the first baseband processor 110 can perform the third generation or more mobile communication (ie, 3G or more) with the external device through the first path and the second path after detecting the SIM card inserted in the first card slot 160. The second baseband processor 120 can perform the third generation or more mobile communication with the external device through the third path and the fourth path after detecting the SIM card inserted in the second card slot 170 connected thereto.

Further, in order to improve the antenna utilization rate and the data transmission rate, when the first baseband processor 110 performs data transmission with the external device, the path connected by the second baseband processor 120 may also be used for data transmission. For example, when the first baseband processor 110 transmits data through the first path, if the third path is idle, the first baseband processor 110 can jointly transmit data through the first path and the third path. For another example, the first baseband processor 110 passes the first pass And when the second path and the fourth path are both idle, the first baseband processor 110 passes the first path, the second path, and the The third path and the fourth path jointly transmit data; or, when the first baseband processor 110 transmits data through the first path and the second path, if the third path is idle, then The first baseband processor 110 collectively transmits data through the first path, the second path, and the third path. The third path is idle or the fourth path is idle, that is, the second baseband processor 120 does not currently transmit data through the third path or the fourth path.

It should be noted that both baseband processors (ie, the first baseband processor and the second baseband processor) support 2G, 3G, and 4G access capabilities. That is, the first baseband processor can support the 4G access capability in addition to the first path and the second path connection, and between the first baseband processor, the first radio frequency chip, and the first antenna, there may be support for 2G and/or Or a path of the 3G access capability; the second baseband processor can be connected to the third path and the fourth path to support the 4G access capability, and between the second baseband processor, the second RF chip, and the second antenna, There may be paths that support 2G and/or 3G access capabilities. When both the first path and the second path are idle (ie, when the first baseband processor does not perform 4G services), the first path and the second path may be used by the second baseband processor, ie, the second baseband processor may 4G services are performed through four paths of the first path, the second path, the third path, and the fourth path; at this time, the first baseband processor can support 2G/3G access capability through other paths, that is, the first baseband processor At this time, 2G/3G services can be performed. Among them, the antenna supporting 2G and 3G can be shared with the antenna supporting 4G, and the antenna duplexer can be shared by the antenna duplexer.

The baseband processor in the embodiments of the present invention may include a Modem (modem) chip, a Modem chip and a CPU, or a Modem chip and a Digital Signal Processor (DSP). The baseband processor may be composed of a circuit or an integrated circuit (IC), for example, may be composed of a single package IC, or may be composed of a plurality of package ICs that have the same function or different functions. In the terminal device, the baseband processor and the application processor can be independent devices or integrated in one device.

The following describes the communication working principle of the terminal 100 in combination with specific examples:

When the terminal 100 is powered on, the first baseband processor 110 and the second baseband processor 120 respectively search for the camped cell supported by the SIM card connected thereto, and according to the identity of the SIM card connected thereto. The different information is respectively connected to the communication network corresponding to the resident cell. For example, the first baseband processor 110 is connected to the 4G SIM card of the mobile operator (an operator) through the first card slot 160, and the second baseband processor 120 is connected to the Unicom carrier through the second card slot 170 (an operation) a 4G SIM card, the first baseband processor 110 establishes a connection with the mobile network of the camping cell through the first path and the second path, and the second baseband processor 120 passes the third path and the fourth path with the camping cell The Unicom network establishes a connection.

In this example, the first antenna 151 and the third antenna 153 of the terminal are main set antennas, and the second antenna 152 and the fourth antenna 154 are diversity antennas. When the first baseband processor 110 receives the processing request of the uplink service, such as the data upload service request, the first baseband processor 110 sends the uplink data through the first path, and at this time, the first baseband processor 110 determines the connection thereof. After the mobile network can support the multi-path transmission, it is determined whether the third path of the second baseband processor 120 connected for transmitting the uplink data is idle, and if idle, the first path and the third path are jointly connected to the mobile network. And transmitting the uplink data to the mobile network through the first path and the third path. When the uplink data transmission is completed, the first baseband processor 110 may release the third path.

When the first baseband processor 110 receives the processing request of the downlink service, such as the data download service request, the first baseband processor 110 receives the downlink data through the first path and the second path, and at this time, the first baseband processor 110 is After determining that the connected mobile network can support multi-path transmission, it is determined whether the third path and the fourth path that are connected to the second baseband processor 120 for transmitting downlink data are idle, and if idle, the third path and the third path may be used. At least one of the four paths cooperates with the first path and the second path to access the mobile network, and receives the downlink of the mobile network transmission through the at least one of the third path and the fourth path together with the first path and the second path. data. When the downlink data transmission is completed, the first baseband processor may release the occupied third channel and/or the fourth path.

The first baseband processor 110 can select any one or two of the third path and the fourth path to transmit data according to the network to which it is connected or the needs of the service to be processed. The requirements of the service include the amount of data to be transmitted by the service, requirements for communication rate and quality, and the like. For example, if the network connected by the first baseband processor 110 supports only three channels of data transmission, or the current service does not require high communication quality, and the amount of transmitted data is not large, the first baseband processor 110 may select only the third path and The first path and the second path transmit data, and if the connected network can support four channels of data transmission, or the current task has high communication quality or a large amount of transmitted data, the first baseband processing The device 110 can select the third path, the fourth path, and the first path and the second path to transmit data.

Among them, when multiple antennas are used for transmitting or receiving data, a MIMO (Multiple-Input Multiple-Output) technique can be used. When the first baseband processor 110 and its communication network support MIMO, the first baseband processor 110 may form an MIMO antenna on the path on the corresponding path and the antenna on the path corresponding to the second baseband processor. The transmitting end and the receiving end respectively use a plurality of transmitting antennas and receiving antennas, so that signals are transmitted and received through multiple antennas at the transmitting end and the receiving end to improve data transmission quality. For example, the first baseband processor 110 transmits uplink data through the first path, and when the third path is idle, the first antenna and the third antenna form a MIMO antenna to transmit uplink data; for example, the first baseband processor 110 passes the first The path and the second path receive downlink data, and when the third path is idle, the first antenna, the second antenna, and the third antenna are combined to form a MIMO antenna to receive downlink data.

It can be understood that when the first baseband processor 110 transmits data through the path connected by the second baseband processor 120, if it is detected that the second baseband processor 120 has a data transmission requirement, the second baseband processor 120 is connected. At least one path for the second baseband processor 120 to transmit data through the yielded path.

In the terminal 100, the second baseband processor 120 can be similar to the first baseband processor 110. When data is transmitted with an external device, the path connected by the first baseband processor 110 can also be used for data transmission. For example, the second baseband processor 120 is coupled to the first radio frequency chip 130 via a switch 180. By controlling the switch 180, the second baseband processor 120 can be connected or disconnected from the first or second path. When the second baseband processor 120 transmits data through the third path, if the first path is idle, the second baseband processor 120 transmits data through the first path and the third path. For another example, when the second baseband processor 120 transmits data through the third path and the fourth path, if the first path and the second path are both idle, the second baseband processor 120 passes through The first path, the second path, the third path, and the fourth path jointly transmit data; or, when the second baseband processor 120 transmits data through the third path and the fourth path And if the first path is idle, the second baseband processor 120 jointly transmits data through the first path, the third path, and the fourth path. For a detailed description, refer to the specific description of the communication manner of the first baseband processor, which is not described herein.

It should be noted that, in this embodiment, the second antenna 152 and the fourth antenna 154 are independently disposed in the terminal 100, and the first baseband processor 110 and the second baseband processor 120 are independently disposed in the terminal 100. In the terminal 100, the first radio frequency chip 130 and the second radio frequency chip 140 are independently disposed in the terminal 100. In other embodiments, the second antenna 152 and the fourth antenna 154 may be the same antenna, and the first baseband processor 110 and the second baseband processor 120 may also be integrated in one processor 192, the first radio frequency chip 130 and The second RF chip 140 can also be disposed in the same RF chip 191, as shown in FIG. The second antenna 152 and the fourth antenna 154 are the same antenna, for example, a diversity antenna. That is, the first baseband processor 110 and the second baseband processor 120 can share one diversity antenna.

For example, if the network connected by the first baseband processor supports only three channels of data transmission, or the current service does not require high communication quality, and the amount of transmitted data is not large, the first baseband processor may select only the third path and the first. The path and the second path transmit data. If the connected network can support four channels of data transmission, or the current task has high communication quality or a large amount of transmission data, the first baseband processor can select the third path and the fourth path.

Or the first baseband processor combines the first antenna, the second antenna, the third antenna, and the fourth antenna when receiving downlink data through the first path and the second path, and the third path and the fourth path are both idle. The MIMO antenna receives downlink data.
