Description

Technical Field

[0001] The present invention relates to the technical field of communications.

Background Art

[0002] Compared with conventional 3G (Third Generation Mobile Communication Technology) and 4G (Fourth Generation Mobile Communication Technology) systems, the 5G (Fifth Generation Mobile Communication Technology) system can provide a larger bandwidth and a higher data rate, and can support more types of terminals and vertical services. Therefore, when the 5G system is deployed, the frequency is significantly higher than that of 3G and 4G systems. For example, the 5G system can be deployed in the millimeter wave band.

[0003] However, the higher the carrier frequency, the more severe the fading (attenuation) that the signal encounters during transmission. Therefore, when actually deploying the 5G system, especially how to better enhance the cell coverage in the millimeter wave band has become a problem to be solved.

[0004] It should be noted that the introduction of the above background technology is for clearly and completely explaining the technical solution of the present invention and for easy understanding by those skilled in the art. These technical solutions should not be construed as well-known to those skilled in the art just because they are described in the background art of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0005] To better solve the coverage problem when actually deploying a cellular mobile communication system, it is a commonly used deployment means to amplify and transfer the communication signal between the terminal device and the network device using an RF transfer device (RF Relay / Repeater). The RF transfer device has a wide range of applications when actually deploying 3G and 4G systems. Generally speaking, the RF transfer device is a device that amplifies and transfers the reciprocating signal between the network device and the terminal device in the RF band.

[0006] The inventors have discovered the following. That is, regarding the coverage problem encountered when deploying a 5G system, adopting an RF transmitter to enhance coverage is one of the feasible solutions. However, conventional transmitters do not have the ability to communicate with network devices and cannot directly obtain relevant information on uplink and downlink link settings from network devices. Therefore, if such a transmitter is deployed in a 5G system, it can help enhance the signal strength, but it cannot cope with complex environmental changes, so the same RF transmitter cannot achieve the same effect as when deployed in 3G and 4G systems.

[0007] In view of at least one of the above problems, embodiments of the present invention provide a transmitter, a network device, and a communication method thereof. The transmitter has the ability to communicate with the network device. The transmitter receives the indication information of the network, and communicates with the network device on a specified (predetermined) frequency resource and / or transfers signals between the network device and a third device on the specified frequency resource. Setting the frequency resource for the transmitter according to the actual needs of communication and transfer is beneficial to improving the utilization efficiency of radio resources. The transmitter in the embodiments of the present invention can better enhance the signal coverage under the indication of the network and can cope with environmental changes, so the transmission efficiency of the entire network can be improved.

It should be understood that the present invention is not limited to the described embodiments, that is, the present invention also includes all changes, modifications and substitutions within the scope of the appended patent claims.

[0020] In an embodiment of the present invention, the term "communication network" or "wireless communication network" may refer to a network conforming to any of the following communication standards, for example, LTE (Long Term Evolution), LTE-A (LTE-Advanced), WCDMA (registered trademark) (Wideband Code Division Multiple Access), HSPA (High-Speed Packet Access), and the like.

[0027] FIG. 1 is a diagram showing an application scenario of an embodiment of the present invention. As shown in FIG. 1, for the sake of convenience of explanation, one network device (for example, 5G base station gNB) 101, one repeater 102, and one terminal device (UE) 103 are taken as examples for explanation, but the present invention is not limited thereto.

[0028] As shown in FIG. 1, the network device 101 may have a first cell / carrier, and the network device 101, the repeater 102, and the terminal device 103 perform transfer / communication in the first cell, but the present invention is not limited thereto.

[0029] FIG. 2 is another diagram showing an application scenario of an embodiment of the present invention. As shown in FIG. 2, for the sake of convenience of explanation, one network device (for example, 5G base station gNB) 201, one repeater 202, and one terminal device (UE) 203 are taken as examples for explanation, but the present invention is not limited thereto.

To improve the communication quality, the signal between the terminal device 203 and the network device 201 is transferred via the repeater 202. The signal exchange between the network device 201, the terminal device 203, and the repeater 202 adopts a beam-based transmission and reception method.

[0030] As shown in FIG. 2, the network device 201 may have a first cell / carrier, and the network device 201 may further have other cells / carriers in a frequency band / spectrum other than the first cell. The network device 201, the transmitter 202, and the terminal device 203 may perform transfer / communication in the first cell, or may perform transfer / communication in other cells / carriers.

[0031] In an embodiment of the present invention, an existing service (traffic) or a service that can be implemented in the future can be transmitted between the network device and the terminal device. For example, these services may include, but are not limited to, eMBB, mMTC, URLLC, V2X communication, etc.

[0032] In FIGS. 1 and 2, the description is given by taking as an example that the transmitter can transfer signals between the network device and the terminal device, but the present invention is not limited thereto. For example, the transmitter can transfer signals between the first device and the third device as the second device, and can directly communicate with the first device and / or the third device. The first device to the third device may be any device in the aforementioned network. In the following embodiments, the description is given by taking as an example that the first device is a network device and the third device is a terminal device.

[0033] FIG. 3 is a diagram showing a TDD transmitter. As shown in FIG. 3, a time-division duplex (TDD) transmitter has two paths. The antennas on both sides of the transmitter are respectively directed to areas where the network device and the served terminal device may exist, and transfer signals between the network device and the terminal device in a time-division manner.

[0034] Conventional transceivers do not perform demodulation / decoding on the transfer signal during transfer. The direction of the antenna of a conventional transceiver is fixed and is usually manually installed and adjusted during initial installation. As a result, the antenna on the network device side points in the direction of the incoming wave of the network device, and the antenna on the terminal device side points to the location where deployment needs to be enhanced. When a conventional transceiver is working, the direction of the antenna does not change. In addition, a conventional transceiver does not have a communication function and cannot interact with information with the network device, so it does not support being adapted and / or dynamically set by the network device.

[0035] Compared with 3G and 4G systems, the 5G system deployed in relatively high frequency bands and millimeter wave frequency bands adopts more advanced and complex MIMO (Multiple Input Multiple Output) technology. In the 5G system, directional antennas are basic components of network devices and terminal devices, and signal transmission and reception based on beam forming technology are the basic signal transmission methods in the 5G system.

[0036] In particular, the characteristics of high frequency and small wavelength in the millimeter wave band are advantageous for providing network devices and terminal devices with antenna panels including relatively many arrays. The increase in the number of antenna arrays can help with more accurate beam forming, that is, it is easier to form a narrow beam. By concentrating energy on a narrow beam, it is advantageous to strengthen the signal and reduce interference to other devices. In addition, because the pointing accuracy of a narrow beam is high, the requirements for channel measurement and beam management are very high. Therefore, the 5G system supports relatively complex but accurate channel measurement, antenna calibration, and beam management, and the network device can effectively and accurately control the receiving beam and transmitting beam of the terminal device through these schemes to achieve better communication effects.

[0037] Conventional transceivers do not have the ability to communicate with network devices, and the transceivers themselves need to detect / determine relevant uplink / downlink link settings (TDD UL / DL config) within the network. Subsequently, in the downlink time unit of the network, the transceiver switches to the downlink transfer position, that is, receives a signal from the network device side, and after performing processing such as amplification, sends out a signal from the terminal device side. Also, in the uplink time unit of the network, the transceiver switches to the uplink transfer position, that is, receives a signal from the terminal device side, and after performing processing such as amplification, sends out a signal from the network device side.

[0038] Therefore, although conventional transceivers can assist in enhancing signal strength, they cannot be flexible in the face of complex environmental changes, so they may reduce the throughput of the entire network. In order to enable the transfer of the transceiver to adapt flexibly to the characteristics of the 5G network, the network needs to assist the transceiver and set the transfer of the transceiver based on the real-time situation of the network. Also, the transceiver needs to have the ability to communicate with network devices, that is, receive auxiliary information and / or setting information, etc. (such as TDD UL DL settings, instructions to transmit / receive spatial filters, etc.) from the network device side, and it is also required to be able to perform necessary feedback and reporting. Therefore, how to enable the transceiver to communicate efficiently with network devices has become a problem to be solved.

[0039] Hereinafter, various embodiments of the embodiments of the present invention will be described in conjunction with the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0040] In an embodiment of the present invention, the beam may be referred to as a lobe, a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc. Alternatively, it may be denoted as a beam index, a lobe index, a reference signal index, a transmission configuration indication index, a spatial domain filter index, etc. The above-mentioned reference signal is, for example, a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS for a transmitter, an RS transmitted by a transmitter, etc. The above-mentioned TCI may also be referred to as a TCI state.

[0041] In an embodiment of the present invention, the transmitter may further be referred to as a repeater, an RF transmitter, a relay, an RF relay, or may be referred to as a repeater node, a transmitter node, a relay node, or may be denoted as an intelligent repeater, an intelligent transmitter, an intelligent relay, an intelligent repeater node, an intelligent transmitter node, an intelligent relay node, but the present invention is not limited thereto.

[0042] In an embodiment of the present invention, the network device may be a device of the serving cell of the terminal device, may be a device of the cell where the transmitter is located, may be a device of the serving cell of the transmitter, or may be the parent node of the transmitter. However, in the present invention, the name of the transmitter is not limited, and all devices capable of realizing the above functions belong to the scope of the transmitter of the present invention.

[0043] <Embodiment of the first aspect> In an embodiment of the present invention, a communication method of a transmitter is provided and will be described from the transmitter side.

[0044] FIG. 4 is a diagram showing a communication method of a transmitter in an embodiment of the present invention. As shown in FIG. 4, the method includes the following steps (operations).

[0045] 401: The transmitter receives first instruction information from the network device, and the first instruction information is used to instruct and / or set a first frequency resource and / or a second frequency resource.

[0046] Among them, the first frequency resource is used by the transmitter to transmit a first signal generated by the transmitter to the network device, and the second frequency resource is used by the transmitter to transmit a second signal not generated by the transmitter to the network device.

[0047] In some embodiments, the first instruction information may be set and / or instructed by one or more signaling. It may be set and / or instructed by the network device for the transmitter at a certain point in time, or at multiple points in time, respectively, by the network device using one or more of static signaling, semi-static signaling, and dynamic signaling for the transmitter.

[0048] For example, one piece of first instruction information is used to instruct the first frequency resource, and the second frequency resource is pre-defined or pre-set, or is instructed by a network interface (for example, F1). Alternatively, one piece of first instruction information is used to instruct the second frequency resource, and the first frequency resource is pre-defined or pre-set, or is instructed by a network interface (for example, F1).

[0049] Also, for example, one piece of first instruction information is used to instruct the first frequency resource and the second frequency resource.

[0050] Also, for example, one piece of first instruction information is used to instruct the first frequency resource, and another piece of first instruction information is used to instruct the second frequency resource.

[0051] Also, for example, one piece of first indication information is used to indicate a first frequency resource, and a second frequency resource is indicated or set by OAM (Operation Administration and Maintenance).

[0052] In some embodiments, optionally, as shown in FIG. 4, the method may further include the following steps.

[0053] 402: The transmitter transmits a first signal to the network device, and / or the transmitter transfers a second signal to the network device.

[0054] It should be noted that the above-mentioned FIG. 4 is for illustrative purposes of the embodiments of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or some operations can be increased or decreased. A person skilled in the art can make appropriate modifications to the above-mentioned content without being limited to the description of the above-mentioned FIG. 4.

[0055] In the embodiments of the present invention, by indicating and / or setting the first frequency resource and / or the second frequency resource, the communication bandwidth / frequency band and the transfer bandwidth / frequency band can be distinguished. Therefore, the network device can more effectively perform settings on the transmitter, and the transmitter can more effectively transfer signals between the network device and the user device and communicate with the network device.

[0056] Since the transmitter is not a conventional terminal device, the transmitter generally does not have traffic data (e.g., typical terminal device data traffic such as video, web pages, phone calls, etc.). Therefore, between the transmitter and the network device, information interaction is often carried out, such as controlling instructions for transfer settings and auxiliary information, and reports of measurement information and other necessary control information. In other words, the amount of communication data between the transmitter and the network device may not be very large. The frequency resources for communication set by the network device for the transmitter do not have to be many, or the bandwidth does not have to be wide. Also, for the transmitter, the wider its transfer bandwidth (or the larger its transfer frequency range), the more network deployment scenarios it can be applied to, and it can better support network deployment.

[0057] In an embodiment of the present invention, by setting the communication bandwidth / frequency band and the transfer bandwidth / frequency band respectively, it is advantageous for the network device to perform settings on the transmitter more effectively, and for the transmitter to transfer signals more effectively between the network device and the user device and communicate with the network device. For example, the transfer bandwidth / frequency band may be set relatively wide, and the communication bandwidth / frequency band may be set relatively narrow, but the embodiments of the present invention are not limited thereto.

[0058] Thereby, since the frequency resources of the uplink communication and uplink transfer between the transmitter and the network device can be set by the network device, the transfer of the transmitter can be set according to the real-time / actual situation of the network, the signal coverage can be better enhanced, and it can cope with changes in the environment and the main traffic in the cell, etc., thereby improving the transmission efficiency of the entire network.

[0059] In an embodiment of the present invention, the "signal generated by the transmitter" is also referred to as a communication signal, for example. The transmitter performs modulation / coding of the signal, or the transmitter generates and modulates a sequence of reference signals. The "signal not generated by the transmitter" is also referred to as a transfer signal, for example. The transmitter does not perform demodulation / decoding on the signal, and at most performs processing such as amplification. For specific signals, reference can be made to the embodiments described later.

[0060] In some embodiments, the first indication information is further used to indicate and / or set a third frequency resource and / or a fourth frequency resource. Among them, the third frequency resource is used for the transmitter to receive a third signal transmitted to the transmitter by the network device, and the fourth frequency resource is used for the transmitter to receive a fourth signal of the transmitter transfer from the network device.

[0061] For example, one piece of first indication information is used to indicate a third frequency resource, and the fourth frequency resource is predefined or pre-set, or is indicated by a network interface (for example, F1). Alternatively, one piece of first indication information is used to indicate a fourth frequency resource, and the third frequency resource is predefined or pre-set, or is further indicated by a network interface (for example, F1).

[0062] Also, for example, one piece of first indication information is used to indicate a third frequency resource and a fourth frequency resource.

[0063] Also, for example, one piece of first indication information is used to indicate a third frequency resource, and another piece of first indication information is used to indicate a fourth frequency resource.

[0064] Also, for example, one piece of first indication information is used to indicate a third frequency resource, and the fourth frequency resource is indicated or set by OAM.

[0065] In some embodiments, the first indication information may indicate and / or set one or any combination of the first to fourth frequency resources.

[0066] For example, one piece of first indication information is used to indicate the first frequency resource, another piece of first indication information is used to indicate the third frequency resource, and another piece of first indication information is used to indicate the second frequency resource, and another piece of first indication information is used to indicate the fourth frequency resource.

[0067] Also, for example, one piece of first indication information is used to indicate the first frequency resource, another piece of first indication information is used to indicate the third frequency resource, and the second frequency resource and / or the fourth frequency resource are indicated or set by OAM.

[0068] Also, for example, one piece of first indication information is used to indicate the first frequency resource and the third frequency resource, and another piece of first indication information is used to indicate the second frequency resource and the fourth frequency resource.

[0069] Also, for example, one piece of first indication information is used to indicate the first frequency resource and / or the third frequency resource, and the second frequency resource and / or the fourth frequency resource are indicated or set by OAM.

[0070] Thereby, since the frequency resources for downlink communication and downlink transfer between the transmitter and the network device can also be set by the network device, the transfer of the transmitter can be set based on the real-time situation of the network, the signal coverage can be better enhanced, and it can cope with changes in the environment and the main traffic in the cell, etc., thereby improving the transmission efficiency of the entire network.

[0071] In some embodiments, the second frequency resource (uplink transmission bandwidth / frequency band) and / or the fourth frequency resource (downlink transmission bandwidth / frequency band) may be predefined or preconfigured, and / or may not be further indicated by signaling. For example, the transmission bandwidth / frequency band of the transmitter (uplink transmission bandwidth / frequency band and / or downlink transmission bandwidth / frequency band) may be fixed, for example, determined at the time of transmitter design. Also, for example, the transmission bandwidth / frequency band of the transmitter may be set / configurable, for example, set before the transmitter is shipped, and / or these settings may be made when installing and testing the transmitter.

[0072] For example, the first indication information indicates the first frequency resource, and the second frequency resource may be predefined or preconfigured.

[0073] Also, for example, the first indication information indicates the first frequency resource, and the second frequency resource and / or the fourth frequency resource may be predefined or preconfigured.

[0074] Also, for example, the first indication information indicates the first frequency resource and / or the third frequency resource, and the second frequency resource and / or the fourth frequency resource may be predefined or preconfigured.

[0075] Thereby, the frequency resources for uplink transmission and downlink transmission between the transmitter and the network device can be predefined or preconfigured, so that the transmission function can be realized with a simple operation, thereby reducing the implementation cost of the transmitter and enabling the transmitter to be more widely and better applied when deploying the network, and improving the coverage quality and transmission efficiency of the entire network.

[0076] In some embodiments, the first signal is a signal generated by a transmitter and is transmitted to a network device via a first frequency resource. The second signal is obtained by the transmitter at least by amplifying a signal received by the transmitter on a second frequency resource. The third signal is used to carry information and / or data transmitted by the network device to the transmitter, or the third signal is used to configure the transmitter to perform channel estimation and / or measurement. The fourth signal is a signal received by the transmitter on a fourth frequency resource and is transmitted by the transmitter after at least being amplified by the transmitter.

[0077] For example, the first signal includes at least one of the following, namely, a Physical Uplink Shared Channel (PUSCH), a De-Modulation Reference Signal (DMRS), a Sounding Reference Signal (SRS), a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), and a Scheduling Request (SR), but the present invention is not limited thereto.

[0078] In some embodiments, the network device instructs the transmitter to receive the third signal, and the third signal is associated with the ID or parameters of the transmitter.

[0079] For example, the ID may be a cell ID, or a UE ID, or a transmitter ID, or a Radio Network Temporary Identifier (RNTI), etc. The parameter may be a parameter configured by the network device for the transmitter, for example, a parameter for generating a reference signal sequence, etc.

[0080] In some embodiments, the third signal is used to carry information that the network device transmits to the transfer device, and the transfer device obtains the information it carries by demodulating and decoding the third signal.

[0081] In some embodiments, the third signal is used for the transfer device to perform channel estimation or channel measurement, etc., and the transfer device performs signal processing such as corresponding demodulation on the third signal to obtain channel characteristics or channel measurement information for reporting, etc.

[0082] In some embodiments, the third signal may be exclusively transmitted by the network device to the transfer device, for example, it may be a Physical Downlink Shared Channel (PDSCH), etc.

[0083] In some embodiments, the third signal may be transmitted by the network device to a set of devices, and the transfer device is one of the devices in the set of devices. For example, the third signal may be at least one of the following, namely, group common PDCCH, Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSIRS), Tracking Reference Signal (TRS), etc.

[0084] For convenience, a signal directly communicated between the network device and the transfer device, or between the third device (for example, the terminal device) and the transfer device may be called a communication signal. When transmitting a communication signal, the transfer device needs to perform encoding and / or modulation, and when receiving a communication signal, the transfer device needs to perform decoding and / or demodulation. Also, a signal transferred through the transfer device may be referred to as a transfer signal.
