Description

Method and device for transmitting signals in a communication system

[0001] The present disclosure relates to a method and device for transmitting a signal in a communication system.

[0002] In a communications system, communication occurs between a base station and a terminal, and various signals can be transmitted. To facilitate communication between the base station and the terminal, a repeater may be included. The repeater can communicate with the base station and the terminal using analog and digital signals.

[0003] In conventional analog signal transmission devices such as base stations or repeaters, analog signals were transmitted alone, or two or more signals were transmitted using various multiplexing methods (for example, frequency division multiplexing (FDM)). However, in the case of an out-band management channel for providing status management or updates of remotely installed equipment, it is more convenient to perform communication using a digital signal rather than an analog signal, so a method of maintaining the management channel as a separate medium rather than the same medium as the analog signal is used. Alternatively, in repeaters, communication was performed using a method such as Zigbee or FSK (frequency shift keying) by utilizing the guard band or edge band between available bands.

[0004] However, these methods require wired communication, which increases transmission line installation and rental costs, making them expensive and difficult to manage. The slow communication speed makes them unsuitable for rapid firmware updates or real-time control to receive alarm reports. Furthermore, analog signals require separate channels for up / down conversion and for various frequency / phase / time synchronization of the radiation.

[0005] The technical idea of ​​the present disclosure is to solve the problem of increased costs and management difficulties caused by digital signals transmitted separately from analog signals.

[0006] The technical problems to be solved by the technical idea of ​​the present disclosure are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0007] A method performed by a transmitting device in a communication system according to an aspect of the technical idea of ​​the present disclosure may include: a step of obtaining synchronization information; a step of generating an Ethernet frame including synchronization information based on the synchronization information; a step of generating an analog signal based on the synchronization information; a step of combining the Ethernet frame and the analog signal; and a step of transmitting the combined signal to a receiving device via a wired cable.

[0008] According to one embodiment, the step of generating an Ethernet frame including synchronization information based on the synchronization information may include a step of generating the Ethernet frame by including time stamp information in a header of the Ethernet frame.

[0011] According to one embodiment, the method may further include: generating management information; further combining the management information with the combined signal to generate a combined signal; and transmitting the generated combined signal to a receiving device via the wired cable.

[0012] In another aspect of the technical idea of ​​the present disclosure, a method performed by a receiving device in a communication system may include: receiving a signal through a wired cable; separating the received signal to identify an Ethernet frame and an analog signal; obtaining synchronization information from the Ethernet frame; and performing synchronization based on the synchronization information.

[0014] According to one embodiment, the synchronization information may include at least one of a time clock and a frequency clock.

[0015] In one embodiment, the analog signal may be comprised of an intermediate frequency (IF) signal or a radio frequency (RF) signal.

[0016] According to one embodiment, the Ethernet frame may further include management information, and may further include a step of managing and updating an entity of the receiving device based on the management information.

[0017] In another aspect of a communication system according to the technical idea of ​​the present disclosure, a transmitting device comprises a transceiver; and at least one processor, wherein the at least one processor is configured to: obtain synchronization information, generate an Ethernet frame including synchronization information based on the synchronization information, generate an analog signal based on the synchronization information, combine the Ethernet frame and the analog signal, and transmit the combined signal to a receiving device via a wired cable.

[0019] According to the communication method according to the present disclosure, there is no need to establish a management channel and a separate channel for signal synchronization when transmitting an analog signal, so that the cost of laying communication lines can be reduced and their management can be facilitated.

[0020] The effects that can be obtained by embodiments according to the technical idea of ​​the present disclosure are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the technical idea of ​​the present disclosure belongs from the description below.

[0036] Hereinafter, various embodiments according to the technical idea of ​​the present disclosure will be described in detail.

[0037] FIG. 1 illustrates a communication system according to various embodiments of the present disclosure.

[0038] FIG. 1 illustrates a base station (110), a first terminal (120), and a second terminal (130) as some of the nodes utilizing a wireless channel in a communication system. Although FIG. 1 illustrates only one base station, one or more other base stations (or repeaters) identical to or similar to the base station (110) may be further included.

[0039] A base station (110) (or repeater) is a network infrastructure that provides wireless access to terminals (120, 130). The base station (110) has coverage defined as a certain geographical area based on the distance at which a signal can be transmitted. The base station (110) may be referred to as an 'access point (AP),' 'eNodeB (eNB),' '5th generation node,' 'next generation nodeB (gNB),' 'wireless point,' 'transmission / reception point (TRP),' or other terms having an equivalent technical meaning.

[0040] Each of the terminals (120, 130) is a device used by a user and communicates with the base station (110) via a wireless channel. The link from the base station (110) to the first terminal (120) or the second terminal (130) is referred to as a downlink (DL), and the link from the first terminal (120) or the second terminal (130) to the base station (110) is referred to as an uplink (UL). In addition, the first terminal (120) and the second terminal (130) may communicate with each other via a wireless channel. In some cases, at least one of the first terminal (120) and the second terminal (130) may be operated without the intervention of the user. That is, at least one of the first terminal (120) and the second terminal (130) is a device that performs machine type communication (MTC) and may not be carried by the user. Each of the first terminal (120) and the second terminal (130) may be referred to as a terminal, 'user equipment (UE),' 'customer premises equipment (CPE),' 'mobile station,' 'subscriber station,' 'remote terminal,' 'wireless terminal,' 'electronic device,' 'user device,' or other terms having equivalent technical meanings.

[0041] FIG. 2 is a diagram showing the frequency and bandwidth of various signals according to one embodiment of the present disclosure.

[0042] Referring to Figure 2, it can be seen that digital and analog signals are distributed according to frequency bands. The bandwidth of the signal can largely include a digital bandwidth (210), an intermediate frequency (IF) frequency bandwidth (220), and a radio frequency (RF) frequency bandwidth (230).

[0043] RF stands for high frequency or radiated frequency, and refers to signals that use bandwidths from several hundred megahertz to several gigahertz.

[0044] Digital bandwidth is a concept that utilizes short-distance communication to transmit digital signals transmitted over wires and typically includes the baseband.

[0045] IF is an intermediate frequency signal located in the middle frequency band of RF, a wireless transmission / reception signal, and digital signals, and is used for circuit stability and cost savings.

[0046] Analog signals used in repeaters, etc. can be transmitted by down-converting (D / C) (240) an RF band signal (230) into an IF band signal (220). Here, the IF frequency bandwidth (220) to be D / C'd can generally use a band of several tens of MHz to several hundred MHz.

[0047] In the case of digital signals used in repeaters, etc., most of them use a digital bandwidth (210) as a baseband band signal that does not perform modulation, and do not overlap with the IF frequency bandwidth (220). Therefore, it may be possible to transmit one or more IF signals and a digital signal for management without interference based on a single communication medium.

[0048] FIG. 3 is a block diagram showing a communication method between communication devices according to one embodiment of the present invention.

[0049] The transmitting device (310) and receiving device (320) of FIG. 3 may be the base station (110), repeater, or terminal (120, 130) of FIGS. 1 and 2. FIG. 3 may be a drawing showing a communication method between conventional electronic devices.

[0050] Referring to FIG. 3, the transmitting device (310) and the receiving device (320) can communicate via an analog signal (330). For example, the transmitting device (310) and the receiving device (320) can communicate in an analog manner via an IF signal or an RF signal. A digital management channel (350) for management can be connected between the transmitting device (310) and the receiving device (320). In addition, a synchronization channel (340) for synchronization can be connected between the transmitting device (310) and the receiving device (320). The digital channel (350) and the synchronization channel (340) can be connected via a wired cable (e.g., an Unshielded Twisted Pair (UTP) cable).

[0051] A digital management channel (350) can be used to transmit signals for management and updates of remote devices. A transmitting device (310) can transmit signals for firmware updates of a receiving device (320), management of units, etc., through the digital management channel (350).

[0052] A synchronization channel (340) can be used to transmit a synchronization signal to ensure synchronization between remote devices.

[0053] Conventionally, it was necessary to configure a communication medium for analog signals, a digital management channel (350) for transmitting signals for managing and updating remote devices, and a synchronization channel (340) for transmitting synchronization signals for synchronization. This method was problematic because it increased the cost of laying or renting transmission lines for each channel and required direct management of wired cables. Therefore, a solution to these problems was required.

[0054] FIG. 4 is a diagram illustrating a signal medium sharing method of an electronic device according to one embodiment of the present disclosure.

[0055] The transmitting device (450) and the receiving device (460) of FIG. 4 may be identical or similar to the transmitting device (310) and the receiving device (320) described in FIG. 3, respectively.

[0056] Referring to FIG. 4, the transmitter (450) may include a microcontroller unit (MCU) (402), an Ethernet physical layer (Ethernet PHY) (404), a low pass filter (LPF) (406), a reference clock (Ref Clk) (408), a phase locked loop (PLL) (410), an analog circuit (412), a transformer (414), a connector (e.g., RJ-45) (416), and optionally, a time stamp function (418).

[0057] The receiving device (460) may include a microcontroller unit (MCU) (422), an Ethernet physical layer (Ethernet PHY) (424), a low pass filter (LPF) (426), a phase locked loop (PLL) (430), an analog circuit (432), a transformer (434), a connector (e.g., RJ-45) (436), and optionally a time stamp function (438).

[0058] The MCU (402, 422) can determine the overall control and execution of operations for each of the transmitting device (450) and the receiving device (460). For example, it can be expressed as a processor or a control unit.

[0059] The Ethernet PHY (404, 424) is used to physically connect devices and can be used as a network for fast and reliable Ethernet data communication. The Ethernet PHY (404, 424) can be used as a direct interface to a MAC (medium access controller) device in the digital domain. Communication can be achieved by utilizing various MII layer interfaces such as MCU (402, 422) and MII (media independent interface) or reduced MII (RMII). The Ethernet PHY (404, 424) can transmit an Ethernet signal to the LPF (406). The Ethernet signal can include synchronization information. The Ethernet signal can include time stamp information.

[0060] The LPF (406, 426) can perform the function of passing only the low frequency band. In other words, it can be used to remove signals in the high frequency band. The signals that pass through the LPF (406, 426) can only remain as IF signals and digital band signals. The LPF (406) can perform filtering on the digital signal received from the Ethernet PHY (404) and the IF signal received from the analog circuit (412).

[0061] Ref Clk (408) can serve to provide a timing reference signal to the device. In the case of a time generator, it can provide an accurate time reference, and in the case of a frequency generator, it can provide a frequency reference for frequency synchronization.

[0062] The PLL (410, 430) can play a role in fixing the phase of a periodic signal to a desired, precise frequency without fluctuation through a reference frequency. It can generally be used to convert an RF signal into an IF signal. The PLL (410, 430) can determine and transmit a clock for an IF signal based on synchronization information received from Ref Clk (408) to an analog circuit (412, 432). The PLL (410, 430) can transmit the synchronization information received from Ref Clk (408) to an Ethernet PHY (404, 424).

[0063] The analog circuit (412, 432) can control and perform overall operations for performing analog communication. The analog circuit (412, 432) can manipulate electronic signals, such as the size, shape, or frequency of a wave, in a non-digital manner. The analog circuit (412, 432) refers to a circuit that receives a continuous input signal and sends a continuous output signal, and can recognize the signal as a continuous voltage amount. The analog circuit (412, 432) can generate an IF signal based on an IF clock received from a PLL and transmit it to the LPF (406, 426). The IF signal can include synchronization information.

[0064] Transformers (414, 434) can be used to combine signals.

[0065] Connectors (416, 436) may represent modular interconnect devices for data communication. Typically, they may include eight contacts and eight wire positions. They may serve as connectors for using UTP cables.

[0066] The timestamp function (418, 438) can be utilized for synchronization by indicating the exact date and time of a specific event. For example, the date can be expressed as a calendar date and the time as a time of day. The transmitter (450) and receiver (460) may optionally include the timestamp function (418, 438). The MCU (402, 422) can generate a timestamp by sending a signal to the timestamp function (418, 438).

[0067] According to one embodiment, an Ethernet frame generated in an MCU (402) of a transmitting device (450) may be transmitted to an LPF (406) via an Ethernet PHY (404). A Ref Clk (408) may generate a time or frequency clock and transmit it to a PLL (410). The PLL (410) may transmit the generated clock to the Ethernet PHY (404) and an analog circuit (412). The analog circuit (412) may generate an IF signal based on the received clock information and transmit it to the LPF (406). The LPF (406) may receive an Ethernet signal and an IF signal including clock information and generate a combined signal. The combined signal may be transmitted as a single signal to a receiving device (460) via a cable (e.g., a UTP cable) (420) through a transformer (414) and a connector (416). The transmission device (450) can generate synchronization information and utilize synchronization information included in a signal received from another external device. The MCU (402) can add time stamp information to the header by transmitting an Ethernet signal to the time stamp function (418). The time stamp information can include transmission time information and frequency synchronization information.

[0068] According to one embodiment, the receiving device (460) can receive a signal that combines an analog signal and an Ethernet signal through a cable (420). The received signal passes through a connector (436) and a transformer (434) to an LPF (426), and can be separated into an Ethernet signal and an analog signal. There can be one or more analog signals and can be transmitted to an analog circuit (432). The analog signal can include synchronization information. The LPF (426) can transmit the Ethernet signal to an Ethernet PHY (424). The Ethernet signal can include synchronization information. The Ethernet signal can include time stamp information. If the Ethernet signal includes time stamp information, the Ethernet PHY (424) can identify the time stamp information by transmitting a signal to a time stamp function (438). If the Ethernet signal does not include time stamp information, the Ethernet PHY (424) can transmit a signal to an MCU (422). The Ethernet PHY (424) can transmit synchronization information included in an Ethernet signal to the PLL (430). The PLL (430) can receive and interpret the synchronization information, generate an IF clock, and transmit it to the analog circuit (432). The LPF (426) can transmit a signal including analog clock information to the analog circuit (432). The receiving device (460) can perform synchronization based on the received synchronization information.

[0069] Here, the combined signal may be a combination of an analog signal (e.g., an IF signal) and an Ethernet signal containing synchronization information. In another embodiment, the combined signal may be a combination of an analog signal (e.g., an IF signal) and an Ethernet signal containing synchronization information and information for device management. In addition, the transmitting device (450) may perform synchronization based on the synchronization information of a signal received from an external source and generate a synchronization signal using the synchronized information.

[0070] The transmitter (450) and receiver (460) do not necessarily have to include each entity illustrated in the drawing and may optionally include entities. Furthermore, it should be understood that the transmitter (450) and receiver (460) may not utilize individual functions of entities even if they include them.

[0071] Through the communication system of Fig. 4, separate communication lines for a channel for signal synchronization of a remote analog signal transmission device and a channel for management can be saved.

In addition, the transceiver (520) can receive signals via a wireless path or a wired path such as a fiber and transmit them to the processor (510), and transmit a signal determined and output from the processor (510) via the channel.
