According to one embodiment, when the first communication control module 451 and the second communication control module 453 share at least some ports, the switch module 460 may be configured inside the communication control module 450. Additional information regarding how the communication control module 450 processes the signal of the first communication network or the signal of the second communication network is described below with reference to Figs.
5 shows a signal flow when an electronic device (e.g., the electronic device 400) according to various embodiments communicates with a first communication network (e.g., a CS network). The electronic device 400 can transmit and receive signals of the first communication network. According to one embodiment, the first communication control module 451 can control the transmission / reception module 410 to transmit and receive signals of the first communication network. For example, the first communication control module 451 may be connected to the transmission module 411 through the switch module 460 to transmit a signal corresponding to the first communication network to the transmission module 411. In addition, a signal transmitted to the transmission module 411 may be transmitted to the first communication network through the duplexer 490 or the first antenna 473.
The first communication control module 451 is connected to the receiving module 415 through the switch module 460 and can receive the signal of the first communication network transmitted through the first antenna 473. In this case, for example, the first communication control module 451 can receive the signal of the first communication network through the first receiver port (e.g., Rx1). Also, the first communication control module 451 may control the first receiving module 430 to receive the signal of the first communication network. A signal of the first communication network received by the first receiving module 430 through the second antenna 475 may be received by the first communication control module 451. In this case, for example, the signal of the first communication network received at the first receiving module 430 may be transmitted to the second receiver port (e.g., Rx2) of the first communication control module 451. [
According to one embodiment, the first communication control module 451 may receive the signal of the first communication network through the receiving module 415 and the first receiving module 430. For example, the first communication control module 451 may receive the signal of the first communication network using both the first antenna 473 and the second antenna 475. This makes it possible for the first communication control module 451 to obtain a diversity gain for the signal of the first communication network. When the receiving module 415 and the first receiving module 430 receive the signal of the first communication network, the second communication control module 453 may be in an idle or OOS (Out of Service) state .
If the electronic device 400 does not communicate with the first communication network (e.g., the CS network), for example, when the user ends a voice call, the communication control module 450 transmits the voice call to the second communication network : PS network) can be transmitted or received and processed.
According to one embodiment, when the communication control module 450 desires to receive a paging signal of the second communication network (e.g., PS network), the first receiving module 430 transmits the paging signal of the second communication network So that the paging signal can be received. For example, Rx1 or Rx2 of the second communication control module 453 may be connected to the first receiving module 430 through the switch module 460. [ In this case, the second communication control module 453 can receive the paging signal of the second communication network received by the first receiving module 430 through the second antenna 475. According to one embodiment, even when the electronic device 400 communicates with the first communication network, the first receiving module 430 may receive a signal (e.g., a broadcasting signal or a paging signal) of the second communication network.
FIG. 6 illustrates a signal flow when an electronic device (e.g., the electronic device 400) according to various embodiments communicates with a second network (e.g., a PS network). The electronic device 400 can transmit and receive signals of the second communication network. According to one embodiment, the second communication control module 453 can control the transmission / reception module 410 to transmit and receive signals of the second communication network. For example, the second communication control module 453 may be connected to the transmission module 411 through the switch module 460 to transmit a signal corresponding to the second communication network to the transmission module 411. The signal transmitted to the transmission module 411 may be transmitted to the second communication network through the duplexer 490 or the first antenna 473. [
The second communication control module 453 is connected to the receiving module 415 through the switch module 460 and can receive a signal of the second communication network (for example, a PS network signal) transmitted through the first antenna 473. Here, the signal of the PS network includes at least one of a data communication signal (e.g., unicast) transmitted to a specific person and a broadcast signal (e.g., a broadcast signal such as a signal received through a BCH (broadcast channel) of LTE) can do. Also, the signal of the PS network may include a multicast signal transmitted to a designated plurality. For example, the second communication control module 453 may receive the signal of the second communication network through a first receiver port (e.g., Rx1). Also, the second communication control module 453 can control the first receiving module 430 to receive the signal of the second communication network. A signal of the second communication network received by the first receiving module 430 through the second antenna 475 may be received by the second communication control module 453. In this case, for example, the signal of the second communication network received at the first receiving module 430 may be transmitted to a second receiver port (e.g., Rx2) of the second communication control module 453. [
According to one embodiment, the second communication control module 453 can receive a signal of the second communication network through the receiving module 415 and the first receiving module 430. For example, the second communication control module 453 may receive signals of the second communication network using both the first antenna 473 and the second antenna 475. This enables the second communication control module 453 to perform multiple input multiple output (MIMO), for example, which is required in the signal of the second communication network (e.g. PS network). When the receiving module 415 and the first receiving module 430 receive the signal of the second communication network, the first communication control module 453 may be in an idle state, for example. Additional information on how the communication control module 450 controls the first receiving module 430 to receive the paging signal of the first communication network is described below with reference to FIG.
FIG. 7 shows a signal flow when an electronic device (the electronic device 400) according to various embodiments receives a paging signal of a first communication network (e.g., a CS network). The electronic device 400 can communicate with, for example, the second communication network. For example, the communication control module 450 may control the transmission / reception module 410 to transmit and receive signals of the second communication network. This is the same as or similar to the portion described in FIG. 6, and thus the description thereof will be omitted.
When the communication control module 450 desires to receive the paging signal of the first communication network (e.g., the CS network), the communication control module 450 may control the first receiving module 430 to receive the paging signal of the first communication network. For example, the first communication control module 451 may be connected to the first receiving module 430 through the switch module 460. The first communication control module 451 may receive the paging signal of the first communication network received by the first receiving module 430 through the second antenna 475. According to one embodiment, a paging signal (e.g., a call signal received via a paging channel in CDMA) of a first communication network (e.g., a CS network) and a paging signal (e.g., For example, the paging signal sent from the Mobile Mobility Entity of the LTE) overlap each other, the communication control module 450 may give priority to the paging signal of the first communication network. Accordingly, even if the user uses a packet service using the second communication network, the voice communication transmitted through the first communication network can be used. When the first receiving module 430 receives the paging signal of the first communication network, the additional information about the signal processing method for the communication control module 450 to transmit and receive the signal of the second communication network is shown in Figs. 9, 13, Is described below with reference to Fig. According to one embodiment, when a high-priority service (VoIP service, for example) is provided through the second communication network, a signal (e.g., a signal for receiving SMS / MSM) (E.g., a paging signal for VoLTE reception) overlap each other, the communication control module 450 may give priority to the signal of the second communication network.
Hereinafter, with reference to FIG. 8, an electronic device 800 according to various embodiments will be described. The same or similar parts as those of the electronic device 400 described in Fig. 4 among the descriptions related to the electronic device 800 of Fig. 8 are omitted. FIG. 8 shows a block diagram of an electronic device 800 (e.g., an electronic device including the hardware 200) according to various embodiments. According to one embodiment, the electronic device 800 may include a first transmission / reception module 810, a second transmission / reception module 830, a communication control module 850, a switch module 860, an antenna 870, and a duplexer 890. According to one embodiment, the first transmission / reception module 810 may include a first transmission module 811 and a first reception module 815, and the second transmission / reception module 830 may include a second transmission module 831 and a second reception module 835 can do. According to one embodiment, the communication control module 850 may include a first communication control module 851 and a second communication control module 853. According to one embodiment, the antenna 870 may include a first antenna 873 and a second antenna 875, and the duplexer 890 may include a first duplexer 891 and a second duplexer 895.
According to one embodiment, the first communication control module 851 and the second communication control module 853 can share the first receiving module 815 and the second receiving module 835 with each other. According to one embodiment, the first transmission module 811 may be the same as or similar to the transmission module 411, and the first reception module 815 may be the same as or similar to the reception module 415. The second transceiver module (e. G., The RF module 234) 830 can transmit signals to, for example, the first communication network or the second communication network and receive signals of the first communication network or the second communication network can do.
The communication control module 850 (e.g., the communication processor 213) controls the first transmission / reception module 810 or the second transmission / reception module 830 to transmit at least one signal of the first communication network or the second communication network Can be processed. According to one embodiment, the first communication control module 851 and the second communication control module 853 share the first receiving module 815 or the second receiving module 835, for example, Signal or the signal of the second communication network simultaneously or sequentially. The signal of the first communication network of the communication control module 850 or the additional information of the signal processing of the second communication network is described below with reference to Table 1.
According to one embodiment, the switch module 860 may include a plurality of switches. For example, the switch module 860 may be composed of two switches corresponding to the receiving module 815 or the first receiving module 835. The switch module 860 connects the reception module 815 or the first reception module 830 with the first communication control module 851 based on a signal processed by the first reception module 815 or the first reception module 835 (For example, switching) to connect with the second communication control module 853.
Since the first antenna 873 or the second antenna 875 is the same as or similar to the first antenna 473 of the electronic device 400, a description thereof will be omitted. The first duplexer 891 may connect the first antenna 873 and the first transmission / reception module 811. The second duplexer 895 may connect the second antenna 873 and the second transmission / reception module 830.
In FIG. 8, the first communication control module 851 can be connected to the first transmission module 811, or the second communication control module 853 can be connected to the second transmission module 831 for convenience of explanation. According to one embodiment, the first communication control module 851 and the second communication control module 853 can share at least one of the first transmission module 811 or the second transmission module 831 with each other. For example, when a MIMO implementation is required, for example, an uplink MIMO (uplink MIMO) is required, the second communication control module 853 transmits a signal to the second communication network The first transmission control module 815 and the second transmission control module 831.
According to one embodiment, the first communication control module 851 may be connected to the first transmission module 811 and the second transmission module 831. According to one embodiment, when the first communication control module 851 and the second communication control module 853 share at least one of the first transmission module 811 or the second transmission module 831, the switch module 860 is configured The internal circuitry may vary. The first communication control module 851 or the second communication control module 853 may further include at least one transmitter for sharing the first transmission module 811 or the second transmission module 831.
Hereinafter, the signal processing of the first communication control module 851 or the second communication control module 853 will be described with reference to [Table 1]. Table 1 shows the first to fourth states according to whether the electronic device 800 is connected to the first communication network or the second communication network. The first communication network may be, for example, a CS network, and in Table 1, cdma1x in the CS network is shown as an example. The second communication network may be, for example, a PS network. In [Table 1], LTE among the PS networks is shown as an example. Other examples of the CS network and the PS network are as described above.

The "idle" state may indicate, for example, that the electronic device 800 has no radio connection with the communication network (e.g., the first communication network or the second communication network). In the "idle" state, the electronic device 800 may monitor the paging signal of the first communication network or the second communication network.
The "connected" state may indicate, for example, a state in which the electronic device 800 can establish a wireless connection with the communication network and transmit / receive signals to / from each other. In the "connected" state, the electronic device 800 can exchange control messages, for example, with the communication network, and can send and receive user data. For example, in the "connected" state, the electronic device 800 may be a data service, voice call, base station registration (e.g., LTE attach or cdma1x registration) To the base station of the base station (BS).
In the first state of Table 1 above, the first communication control module 851 (e.g. cdma1x system) and the second communication control module 853 (e.g. LTE system) may all be idle. In the first state, the first communication control module 851 (e.g., cdma1x system) or the second communication control module 853 (e.g., LTE system) includes at least one of the first receiving module 813 or the second receiving module 835 Can be used to monitor the paging signal.
According to one embodiment, the first communication control module 851 may be connected to one of the first receiving module 815 or the second receiving module 835 to receive a paging signal of the first communication network (e.g., cdma1x). The second communication control module 853 may be connected to another one of the first receiving module 815 or the second receiving module 835 to receive a paging signal of the second communication network (e.g., LTE). For example, since different communication systems use different paging cycles, each communication system (e.g., the first communication control module 851 or the second communication control module 853) Rx path) may be used to receive the paging signal. Further, each communication system can control on / off for each receiving path.
According to one embodiment, each of the first communication control module 851 and the second communication control module 853 monitors the paging signal or receives a signal using both the first receiving module 815 and the second receiving module 835 . For example, the first communication control module 851 has priority over the second communication control module 853, so that the first communication control module 853 transmits the first The receiving module 815 may be used as the first receiving path, and the second receiving module 835 may be used as the second receiving path. For example, the first communication control module 851 may also have priority over a receiving path (e.g., the second receiving path) allocated to the second communication control module 853. [ In this case, the second communication control module 853 transmits the allocation (for example, the second transmission path) allocated to the second communication control module 853 to the second communication control module 853, The receiving path can be used only when the receiving path is not used. According to another embodiment, the second communication control module 853 has priority over the first communication control module 851, so that the second communication control module 853 can receive the signal of the second communication network The first receiving module 815 may be used as the first receiving path, and the second receiving module 835 may be used as the second receiving path. For example, the second communication control module 853 may also have priority over a receiving path (e.g., the first receiving path) allocated to the first communication control module 851. [
According to one embodiment, the first communication control module 851 (e.g., cdma1x system) may be configured to obtain diversity gain using a plurality of receiving modules (e.g., the first receiving module 815 and the second receiving module 835) , Two receiving modules (for example, two receiving paths) can be used. For example, when the signal intensity of cdma1x is weak (for example, when a BER value that is lower than a predetermined dB or a predetermined BER value is obtained), the first communication control module 851 determines Both receiving paths can be used. According to another embodiment, the second communication control module 853 (e.g., an LTE system) may use two receiving modules (for example, a first receiving module, a second receiving module, and a second receiving module) when obtaining a diversity gain using a plurality of receiving modules, Two receiving paths) can be used.
Also, the first communication control module 851 may be configured such that, for example, when the reception strength of the paging signal of the first communication network is low (e.g., when the first communication control module 851 does not detect the paging signal of the first communication network The first communication control module 851 can receive the paging signal using both of the two receiving paths. For example, if the paging signal strength of the cdma1x is below the threshold, the first communication control module 851 can use both of the two receiving paths. If the paging signal strength of the cdma1x is sufficiently large, for example, If the threshold value is exceeded, the first communication control module 851 can use any one of the two receiving paths. In addition, when the user interrupts the LTE communication due to another cause, for example, the first communication control module 851 can use both of the two receiving paths. The first communication control module 851 can use the two receiving paths dynamically according to various causes (e.g., cdma1x signal strength, diversity requirement, paging signal or LTE network interception).
When the first communication control module 851 (e.g., cdma1x) uses the two receiving paths, the signal of the second communication network (e.g., data service through the LTE network) may not be processed in real time. The data reception of the LTE network may be lower in priority than the reception of the cdma1x signal, and the user may not feel a great inconvenience because the need for real-time processing is relatively low. For example, an email server may send a paging signal to the electronic device 800 indicating that an email has arrived, but the electronic device 800 may not receive the paging signal. In this case, email arrival confirmation may be delayed somewhat, but it is unlikely to be a major issue for users.
According to one embodiment, when the second communication network (e.g., LTE) supports a service having a high priority (e.g., voice service), the second communication control module has priority and transmits the first receiving module and the second receiving module And receive signals of the second communication network using at least one of the receiving modules. When the second communication control module 853 uses both of the two receiving paths, the signal of the first communication network may not be processed in real time.
In the second state of Table 1 above, the first communication control module 851 (e.g. cdma1x system) may be in a "connected" state with a first communication network (e.g. cdma1x network) (E.g., an LTE system) may be in an "idle" state. In the second state, the electronic device 800 can communicate with the first communication network (e.g., cdma1x network), for example, when the user makes a voice call. For example, the first communication control module 851 may receive one of the two receiving paths (e.g., the first receiving path) and two transmission paths (e.g., a first transmitting path corresponding to the first transmitting module 811) Or a second transmission path corresponding to the second transmission module 831). The first transmission path may be used to communicate with the first transmission path. The second communication control module 853 may receive the paging signal of the second communication network (e.g., LTE network) using another receiving path (e.g., the second receiving path) of the two receiving paths.
Even in the second state, the first communication control module 851 may have priority over the second communication control module 853 based on the various causes. For example, the first communication control module 851 may use both of the two receiving paths based on the priority. In this case, according to one embodiment, the second communication control module 853 can use one receiving path only when it can not receive the paging signal of the second communication network or when receiving the paging signal of the second communication network have. According to one embodiment, in the second state, the second communication control module 853 may take precedence over the first communication control module 851. For example, when the second communication control module 853 provides a high priority service (e.g., voice service, VoIP) through the second communication control module 853, the second communication control module 853 transmits at least one of the two receiving paths Can be used. In this case, the first communication control module 851 can not receive the signal of the first communication network or can receive the signal of the first communication network using a receiving path that is not used by the second communication control module 853 .
In the third state of Table 1 above, the first communication control module 851 (e.g. cdma1x system) may be in the "idle" state, and the second communication control module 853 (e.g. LTE system) And may be in a "connected" state with a network (e.g., LTE network). In the third state, the electronic device 800 can communicate with the second communication network, for example, when the user uses a data service. For example, the second communication control module 853 may use one of the two receiving paths (e.g., the second receiving path) and one of the two transmitting paths (e.g., the second transmitting path) To communicate with the second communication network.
The first communication control module 851 may receive the paging signal of the first communication network (e.g., cdma1x network) using another receiving path (e.g., the first receiving path) of the two receiving paths. According to one embodiment, when the paging signal of the first communication network is received, the first communication control module 851 may use both the first receiving path and the second receiving path. For example, the priority of the paging signal of the first communication network (e.g., cdma1x network) may be higher than that of other signals. Accordingly, when the paging signal of the first communication network is received, the first communication control module 851 can use both of the two receiving paths dynamically based on the various causes. In another embodiment, the priority of the signal of the second communication network may be higher than the priority of the other signal. Therefore, when communicating with the second communication network, the paging signal of the first communication network may not be received or may be limitedly received. For example, when the second communication network does not communicate, or when it operates in the rank 1 mode of the second communication network, the paging signal of the first communication network can be received.
According to one embodiment, the second communication control module 853 may implement transmission and reception of signals of the second communication network by MIMO. When the paging signal of the first communication network is received, one of the two receiving paths may be used to receive the paging signal of the first communication network. The second communication control module 853 can change the reception mode of the signal of the second communication network when a signal of the first communication network (e.g., a paging signal of the first communication network) is received. For example, the second communication control module 853 can change the processing mode of the signal received from the second communication network. Additional information on how the second communication control module 853 can receive the signal of the second communication network, even when the signal of the first communication network is received, is described below with reference to FIG. 9, FIG. 13, .
In the fourth state of Table 1 above, the first communication control module 851 (e.g. cdma1x system) may be connected to the first communication network (e.g. cdma1x network), and the second communication control module 853 : LTE system) may be connected to the second communication network (e.g., LTE network). For example, a user may receive a voice call while using a data service, or may use a data service during a voice call. For example, a user may use a data service such as web surfing while making a voice call. In this case, the electronic device 800 may be switched from the second state to the fourth state or from the third state to the fourth state.
In the fourth state, the first communication control module 851 or the second communication control module 853 may not use the two receiving paths. This is because, for example, in the CS system, it is advantageous for the first communication control module 851 to continue the connection with the CS network because one receiving path is continuously allocated to the first communication control module 851. This is because the second communication control module 853 is a PS system, for example, in a case where it is not a connected DRX (discontinuous reception), a physical downlink According to one embodiment, when the second communication control module 853 is operating in a connected non-continuous reception mode, the second communication control module 853 transmits the second downlink control channel (PDCCH) The first communication control module 851 can use the reception path allocated to the second communication control module 853. Accordingly, the second communication control module 853 can obtain the diversity gain .
Referring again to FIG. 4, the electronic device 400 of FIG. 4 differs from the electronic device 800 of FIG. 8 in that it includes, for example, one transmission module. Accordingly, the electronic device 400 can support the first to third states. The electronic device 400 can interrupt the data service and perform the voice call, for example, when a voice call is received in the data service because the voice call has a higher priority than the data service. According to one embodiment, a user can set a priority of a voice call through the CS network, a data service (e.g., data communication via a PS network, or a voice call) through a user interface. Further, for example, the electronic device (for example, the electronic device 400) may be set differently for the service and the operation system for each condition according to the requirements of the service provider.

In the first state of Table 2, the LTE system (e.g., communication control module 450) of the electronic device 400 may be in an "idle state" in which data communication signals of the PS network are not transmitted or received. In addition, the electronic device 400 may be in a state of not receiving a broadcast signal or a multicast signal of the PS network. In this first state, the communication control module 450 may monitor the paging signal of the first communication network (e.g., the CS network) using at least one of the receiving module 415 and the receiving module 430. [
In the second state of [Table 2], the communication control module 450 transmits a data communication signal (e.g., a signal corresponding to voice call or data) of the PS network to a "connected state" Or may not be receiving a multicast signal. In this second state, the communication control module 450 may monitor the paging signal of the CS network using at least one of the receiving module 415 and the receiving module 430. [ In the third state shown in [Table 2], the communication control module 450 may be in an idle state in which data communication signals of the PS network are not transmitted or received, and in a state capable of receiving broadcast signals or multicast signals of the PS network. For example, the third state may indicate a state where there is no data communication signal transmission / reception of the PS network, but a state capable of receiving a broadcast signal or a multicast signal (e.g., eMBMS) of the PS network. In this third state, the communication control module 450 can monitor the paging signal of the CS network using at least one of the receiving module 415 and the receiving module 430. According to one embodiment, in the third state, the communication control module 450 may control at least one of the transmission / reception module 410 and the reception module 430 to receive a broadcast signal or a multicast signal of the PS network. In addition, the communication control module 450 can monitor the paging signal of the CS network periodically by controlling the receiving module 430. [ In the fourth state of Table 2, the communication control module 450 may be in a "connected state" capable of receiving a data communication signal of the PS network and a state capable of receiving a broadcast signal or a multicast signal of the PS network . For example, the fourth state may indicate a state capable of transmitting / receiving a data communication signal of the PS network and receiving a broadcasting signal or a multicast signal (e. G., EMBMS) of the PS network. In this fourth state, the communication control module 450 can monitor the paging signal of the CS network using at least one of the receiving module 415 and the receiving module 430. [ According to one embodiment, in the fourth state, the communication control module 450 controls the receiving module 415 to receive at least one of a data communication signal, a broadcast signal, or a multicast signal of the PS network, and controls the transmitting module 411 The data communication signal of the PS network can be transmitted. In addition, the communication control module 450 can receive at least one of a data communication signal, a broadcasting signal, or a multicast signal of the PS network by controlling the receiving module 430. In addition, the communication control module 450 can monitor the paging signal of the CS network periodically by controlling the receiving module 430. [
9, when the second communication control module (e.g., the second communication control module 453 or 853) uses one receiving path (e.g., the first receiving path or the second receiving path) A signal processing method will be described. 9 is a timing chart showing the data throughput of the second communication network (e.g., PS network) signal when the paging signal of the first communication network (e.g., CS network) is received. A solid line indicates a signal of a communication network currently being received by the second communication control modules 453 and 853 and a dotted line indicates a signal that the second communication control modules 453 and 853 are not currently receiving but can be received.
According to one embodiment, the second communication control modules 453 and 853 can receive signals of the PS network through the first antennas 473 and 873. [ Also, the second communication control modules 453 and 853 may receive the PS network signal through the second antennas 475 and 875, and may receive the paging signal of the CS network, for example, one period 1T . For example, the second antennas 475 and 875 can convert the signal currently received at the first point of time 901 from the signal of the PS network to the paging signal of the CS network, and at the second point of time 903, It is possible to switch from the paging signal of the CS network to the signal of the PS network. When the second antennas 475 and 875 receive the paging signal of the CS network, the first communication control modules 451 and 851 transmit the paging signal of the CS network in advance, To the second communication control modules 453 and 853, respectively. The timing of receiving the paging signal of the CS network may be determined according to a series of procedures defined in the specification of the first communication network. The first communication control modules 451 and 851 may determine the timing of receiving the paging signal of the CS network The receiving time can be known. Therefore, the first communication control modules 451 and 851 can perform the first feedback in advance to the second communication control modules 453 and 853.
The second communication control modules 453 and 853 receiving the first feedback from the first communication control modules 451 and 851 transmit secondary feedback (e.g., Rank (3)) through the PUCCH (Physical Uplink Control Channel) indicator, or communicating relevant information via a data channel). The second feedback time point to the PS network may be a third time point 905 when the second antennas 475 and 875 are before the first time point 901 when receiving the paging signal of the CS network. The PS network that has received the secondary feedback previously converts the data transmission mode from rank2 mode to rank1 mode (eg, diversity mode) so that the first communication control modules 451 and 851 receive the signals of the CS network The second communication control module 453, 853 may receive the data that has not been lost while the second communication control module 453, 853 (e.g., from the first time point 901 to the second time point 903).
The first communication control modules 451 and 851 may transmit the paging signal of the CS network to the second communication control modules 453 and 853 before the second time point 903, Feedback is available. In addition, the second communication control modules 453 and 853 receiving the primary feedback can perform the secondary feedback to the PS network. For example, the second communication control module 453, 853 may provide the second feedback to the PS network at a fourth time point 907 prior to the second time point 903. Accordingly, the PS network can transmit data in a rank 2 mode, for example, in a period in which the reception of the paging signal of the CS network ends. Accordingly, the second communication control modules 453 and 853 can have the data throughput of the PS network of the maximum value by receiving lossless PS network data.
The timing diagram showing the data throughput of the PS network expands the data throughput of the PS network in the displayed portion 1110 of the second antennas 475 and 875. [ The data processing rate of the PS network may be Max when the second antennas 475 and 875 receive signals of the PS network (e.g., the third time point 905). This is because the second communication control modules 453 and 853 operate in, for example, the rank 2 mode and receive signals of the PS network using both the first antennas 471 and 871 and the second antennas 475 and 875 to be. At the third time point 905, the second communication control modules 453 and 853 provide feedback to the PS network, but the second antennas 475 and 875 may still receive the signals of the PS network. The PS network, which has been fed back in advance at the third time point 905, for example, the first antennas 473 and 873 at a first time point 901 at which the second antennas 475 and 875 receive the paging signal of the CS network It is possible to transmit the signal of the PS network in a rank 1 mode so that data can be correctly received. Accordingly, at the first point in time 901, the data processing rate of the PS network does not become Max, but it may have a value higher than Low without data loss. Similarly, the second communication control module 453 and the second communication control module 853, which have been provided feedback in advance, transmit the paging signal of the PS network to the PS network in a rank 2 mode at a point of time The data processing rate of the PS network can be Max from the third time point 903 by transmitting a signal.
In FIG. 9, the second communication control modules 453 and 853 are implemented as MIMO (multi input multi output) for convenience of description. However, the second communication control modules 453 and 853 may have various embodiments. For example, the second communication control modules 453 and 853 may be implemented in a spatial multiplexing MIMO (SM MIMO) or a space-frequency block code (SFBC) mode in order to process signals of the second communication network. The SM MIMO may be classified into a rank 2 mode in which different data are received through a plurality of antennas or a rank 1 mode in which the same data is received through a plurality of antennas. According to various embodiments, the second communication control modules 453 and 853 may operate in the rank 1 mode or operate in the SFBC mode even if two antennas are used, depending on the implementation mode of the second communication control modules 453 and 853. The settings of the second communication control modules 453 and 853 can be adjusted. For example, when the second communication control modules 453 and 853 operate in SFBC mode or SM MIMO rank 1, the second communication control module 453 and 853 are adjusted while the paging signal of the CS network is received It is possible to improve the reception performance of the PS network. Also, the area where the electronic devices 400 and 800 can operate in the SM MIMO rank 2 mode is mostly restricted to the vicinity of the base station of the second communication network. Accordingly, even when the paging signal of the CS network is received, the reception performance of the signal of the PS network is not significantly affected.
According to one embodiment, a time point at which the paging signal of the CS network is received may be fed back to the base station of the PS network from the base station of the CS network. In this case, the base station of the PS network may change the transmission mode according to the time when the paging signal of the CS network is received. For example, when the electronic device 400 or 800 receives the paging signal of the CS network, the PS network can transmit the signal of the PS network in rank 1 mode. In addition, the PS network can transmit a signal of the PS network in the rank 2 mode when the reception of the paging signal of the CS network is completed in the electronic devices 400 and 800. In this case, the electronic devices 400 and 800 may not provide feedback on the paging signal reception time point of the CS network to the PS network, for example. Based on whether the paging signal of the CS network is received, The reception mode of the signal of the PS network can be changed.
Hereinafter, with reference to FIG. 10, an electronic device 1000 according to various embodiments will be described. Description of the same or similar parts to those of the electronic device 400 or the electronic device 800 among the descriptions related to the electronic device 1000 will be omitted. 10 shows a block diagram of an electronic device 1000 (e.g., an electronic organ including the hardware 200) according to various embodiments. The electronic device 1000 may include a transmission / reception module 1010, a communication control module 1050, and an antenna 1070. According to one embodiment, the transmission / reception module 1010 may include a transmission module 1013, a first reception module 1015, and a second reception module 1017. The antenna 1070 may include a first antenna 1073 and a second antenna 1075 .
According to one embodiment, when a signal of the PS network is received through at least one of the first receiving module 1015 or the second receiving module 1017, at least one of the first receiving module 1015 or the second receiving module 1017 One may receive the signal of the CS network for at least a moment (at least temporarily) prior to the signal of the PS network. For example, the communication control module 1050 can control the transmission / reception module 1010 so that the electronic device 1000 can communicate with the PS network and receive the paging signal of the CS network according to the period of the paging signal of the CS network have.
According to one embodiment, when the signal of the CS network is received through at least one of the first receiving module 1015 or the second receiving module 1017, at least one of the first receiving module 1015 or the second receiving module 1017 One can determine whether to receive a signal from the PS network, based on the received strength of the signal received from the CS network. For example, when the signal strength of the CS network corresponds to a first range (for example, when the service of the CS network can be used even if one antenna is used), the communication control module 1050 determines that the first reception Module 1015 or the second receiving module 1017 to receive the signal of the PS network. In addition, for example, the communication control module 1050 can control the receiving module of the first receiving module 1015 or the second receiving module 1017 to receive a signal of the PS network in which the signal strength of the CS network is relatively weak have.
Alternatively, when the signal strength of the CS network received by the first receiving module 1015 and the second receiving module 1017 is within a second range (e.g., when the service of the CS network can not be reliably used when using one antenna) If so, the communication control module 1015 may not receive the signal of the PS network. The first range or the second range may be set based on, for example, a threshold of the signal strength, and may be varied depending on the state of the electronic device, the setting of the user, the area where the electronic device is located, Can be set.
According to one embodiment, the communication control module 1050 receives, from at least one of the first receiving module 1013 or the second receiving module 1017, a signal from the PS network based on the paging signal of the CS network or the PS network Or not. For example, even when the signal of the CS network takes precedence over the signal of the PS network, when the paging signal of the PS network is received, the signal of the PS network precedes the signal of the CS network The priority of the signal of the PS network is higher than that of the signal of the CS network). In addition, the communication control module 1050 may adjust the priority at the same time each time the paging signal is received, or may adjust the priority differently according to the number of times that the paging signal is not received. For example, when the paging signal of the PS network is received at a predetermined interval (e.g., 3.5 seconds), if the priority of the CS network is prioritized and the first paging signal is not received, a second paging signal is received , The priority of the PS network can be given priority over the priority of the CS network.
Also, when the signal strength of the CS network is, for example, equal to or less than a reference value, the signal of the CS network may precede the paging signal of the PS network. For example, even if the first paging signal of the PS network is not received and the second paging signal of the PS network is received, if the signal strength of the CS network is less than or equal to the reference value, The signal of the PS network can be prioritized. In addition, according to one embodiment, when the paging signal of the CS network and the signal of the PS network are superimposed (for example, at the same time or partially overlapped with each other), the communication control module 1050, for example, The paging signal of the PS network can be given a higher priority than the paging signal of the PS network. This is to reduce the inconvenience of the user by giving priority to the paging signal of the CS network because the user can be more sensitive to the signal of the CS network than the signal of the PS network.
According to an exemplary embodiment, a paging signal of the PS network may be given a priority based on a service provided through the PS network. For example, when the PS network provides voice service and the CS network supports other services (e.g., SMS), the paging signal of the PS network may precede the signal of the CS network. Alternatively, when the voice service of the PS network takes precedence over the voice service of the CS network, the paging signal of the PS network may precede the signal of the CS network.
According to one embodiment, when a signal received by at least one of the first receiving module 1015 or the second receiving module 1017 is changed, the communication control module 1050 transmits feedback to the first communication network or the second communication network feedback can be provided. For example, when a signal received by the first receiving module 1015 or the second receiving module 1017 is changed from a signal received from the PS network to a signal received from the CS network or a signal received from the CS network, If the signal is changed to a signal received from the PS network, the communication control module 1050 may provide feedback to the CS network or the PS network. According to one embodiment, when the paging signal of the CS network or the paging signal of another PS network is received, the receiving module composed of the MIMO among the first receiving module 1015 or the second receiving module 1017 sets the mode of MIMO 1) receiving mode (e.g., rank1 mode) or a second receiving mode (e.g., rank2 mode).
According to one embodiment, when the switching of the reception mode for the PS network signal (e.g. rank2 mode in the rank1 mode or rank1 mode in the rank2 mode) is requested, the communication control module 1050 transmits the reception mode Feedback can be provided prior to the switch point of time. For example, when at least one of the first receiving module 1015 or the second receiving module 1017 receives the paging signal of the CS network, the communication control module 1050 may transmit the paging signal of the CS network, The communication control module 1050 may include a first modem (e.g., the first communication control module 451, 851) for processing the signal of the CS network, or a second modem And a second modem (e.g., the second communication control module 453, 853) for processing signals of the PS network. In addition, when a paging signal is received from the CS network, the first modem may provide feedback to the second modem on receipt of the paging signal. According to one embodiment, the transmission / reception module 1010 may further include a third reception module or a fourth reception module when the PS network provides data service through the CA. For example, the first receiving module or the third receiving module may receive a Pcell (Primary cell) signal or a signal of the CS network, and the second receiving module or the fourth receiving module may receive a Scell (Secondary Cell) Signal or a signal of the CS network. For example, when a signal (e.g., a Pcell and a Scell signal) of the PS network is received through at least one of the first to fourth receiving modules, at least one of the first to fourth receiving modules transmits the CS It is possible to receive a signal received from the network at least for a period of time in preference to a signal received from the PS network.

15 illustrates a method of communication of an electronic device, according to various embodiments. In operation 1510, when a broadcast signal or a multicast signal of the PS network is received through a plurality of reception modules (e.g., the first reception module 1015 and the second reception module 1017) of the electronic device (e.g., electronic device 1000) , At least one of the receiving modules of the electronic device (e.g., at least one of the first receiving module 1015 and the second receiving module 1017) may receive the signal of the CS network at least temporarily (e.g., for a specified time). In operation 1520, some of the receiving modules of the electronic device (e.g., the first receiving module 1015) continue to receive broadcast signals or multicast signals of the PS network, while others (e.g., the second receiving module 1017) The reception of the broadcast signal or the multicast signal of the PS network can be stopped and the signal of the CS network can be received.
Hereinafter, referring to Fig. 16, an electronic device 1600 according to various embodiments will be described. Description of the same or similar parts to those of the electronic device 400, the electronic device 800, or the electronic device 1000 among the descriptions related to the electronic device 1600 will be omitted. 16 shows a block diagram of an electronic device 1600 according to various embodiments (e.g., an electronic organ including the hardware 200). The electronic device 1600 may include a transceiver module 1610, a communication control module 1650, and an antenna 1670. According to one embodiment, the transmission / reception module 1610 may include a first transmission module 1611, a first reception module 1613, a second reception module 1615, a third reception module 1617, a fourth reception module 1619, and a second transmission module 1621 have. According to one embodiment, the transmission / reception module 1610 may be composed of a plurality of sub-transmission / reception modules. For example, a first sub-transmission / reception module composed of a first transmission module 1611, a first reception module 1613 and a second reception module 1615, and a second sub-transmission / reception module composed of a second transmission module 1621, a third reception module 1617 and a fourth reception module 1619 The second transmission / reception module 1610 may be configured as a second sub transmission / reception module. The antenna 1670 may include a plurality of antennas. For example, the number of antennas or the configuration of the antenna 1670 may be changed according to a frequency characteristic or design scheme supported by the electronic device 1600.
According to one embodiment, when a signal of a first communication network (e.g., a PS network) is received through at least one of the first receiving module 1613 and the fourth receiving module 1619, 4 receiving module 1619 may at least temporarily receive signals of a second communication network (e.g., a CS network) prior to signals of the first communication network. For example, the communication control module 1650 controls the transmission / reception module 1610 so that the electronic device 1600 can communicate with the first communication network and receive the paging signal of the second communication network according to the period of the paging signal of the second communication network. Can be controlled.
According to one embodiment, when the communication control module 1650 performs communication using the Downlink CA method, the communication control module 1650 determines that the first receiving module 1613 and the second receiving module 1615 transmit the first signal (e.g., Pcell signal) and the third receiving module 1617 and the fourth receiving module 1619 to receive a second signal (e.g., a Scell signal) of the PS network. In this case, the communication control module 1650 can control that at least one of the first receiving module 1613 to the fourth receiving module 1619 receives the signal of the CS network at least temporarily for a time in advance of the signal of the PS network. In this case, the communication control module 1650 may determine at least one receiving module for receiving signals of the CS network, based on the quality or characteristics (e.g., signal strength or reception ratio) of signals received at each receiving module have. Alternatively, the communication control module 1650 may transmit at least one of the third receiving module 1617 or the fourth receiving module 1619 when the second signal of the PS network is not received (for example, when Scell add or activation is not performed) To control the reception of the signal of the CS network.
