Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a transmission method and a communication device.
Background
Currently, it is determined that the medium-high frequency bands 3.3GHz-3.6GHz and 4.8GHz-5.0GHz can be divided into the working frequency bands of the fifth Generation mobile communication technology (5th-Generation, 5G) system. However, as the frequency band is higher, the coverage capability is worse, and the uplink power of the terminal is limited, the uplink coverage is more likely to become a bottleneck, and how to improve the uplink performance of the 5G system has become an important target for deploying the 5G system.
In order to improve the uplink performance of the 5G system, the current countermeasure is to adopt a 5G uplink and downlink decoupling technology, also called Supplemental UL Link (SUL), to break the limitation that uplink and downlink are bound to the same frequency band, and transmit the 5G uplink signal through a lower frequency spectrum, such as an a frequency band (2010 to 2025MHz) in a Time Division duplex (Time Division duplex) system, while enjoying 3.5GHz downlink large capacity, so as to improve network coverage. Specifically, for the edge user equipment, when the uplink coverage of 3.5GHz is weak, the SUL function can be activated, so that the uplink of the user is converted to the low frequency for transmission, and the downlink still stays in the 3.5GHz band, thereby greatly enhancing the uplink coverage performance and the edge rate, and improving the user experience of the edge user.
An SUL scheme is introduced into an existing frequency band, and generally, 4G devices and 5G devices on a low frequency band are considered to be deployed by the same manufacturer, so that the 4G devices can be multiplexed, including a Radio Remote Unit (RRU) and an antenna, to receive a 5G uplink signal carried on the same low frequency band, thereby implementing a SUL function. For example, for an 8-antenna TD-LTE system supporting the FA band, since the F band is closer to the a band, the corresponding RRU will support the FA dual band at the same time. If the 5G system is deployed in a frequency band of 3.5GHz (i.e., an a frequency band), a large-scale multiple-input multiple-output (Massive-MIMO) Active Antenna processing Unit (AAU) device may be used.
When the SUL scheme is introduced into the frequency band A, most of the RRUs supporting the FA frequency band in the existing TD-LTE system adopt a design framework of an FA broadband transceiver, for example, FA broadband power amplification is adopted, so that stray signals on the frequency band A are not inhibited at all, and the SUL receiving performance of the frequency band A deployed in the same station is influenced. In order to solve this problem, it is necessary to ensure that there is sufficient isolation between the RRU supporting the FA band and the SUL receiving device (which may be an independent device or integrated on the 3.5GHz Massive-MIMO AAU) of the a band. However, in practical applications, when the FA band RRU and the a band SUL receiving devices are deployed in the same station, the requirement of isolation is difficult to be met due to limited spatial isolation.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a communication device 1 for supplementing an uplink, which communication device 1 may also be referred to as a SUL extension device. As shown in fig. 1, the communication device 1 may include a first port 11, a second port 12, a third port 13, at least one splitter (only 2 splitters are shown in fig. 1, but the embodiment of the present invention is not limited thereto, for example, 8 splitters may also be included) 14, and an SUL receiving device 15 for supporting the SUL function.
Wherein, the first port 11 is connected with the multi-channel antenna 2 supporting multiple frequency bands and the at least one splitter 14, the second port 12 is connected with the first RRU3 of the first network and the at least one splitter 14, the third port 13 is connected with the second BBU4 of the second network and the SUL receiving device 15, and the at least one splitter 14 is connected with the SUL receiving device 15.
The first network and the second network have different communication protocols. For example, the first network may be selected as a 4G network, and the second network may be selected as a 5G network, but the embodiment of the present invention is not limited thereto.
Optionally, the first port 11 and the multi-channel antenna 2 supporting multiple frequency bands may be connected by a radio frequency feeder, the second port 12 and the first RRU3 may also be connected by a radio frequency feeder, and the third port 13 and the second BBU4 may also be connected by a radio frequency feeder.
Optionally, referring to fig. 1, a low noise amplifier 16 may be disposed between the at least one splitter 14 and the SUL receiving device 15 for amplifying the signal flowing through. The at least one splitter 14 may also perform filtering while separating signals of different frequency bands.
Specifically, when transmitting in the uplink, the first port 11 can be used to receive uplink signals of multiple frequency bands from the multi-channel antenna 2; the at least one splitter 14 is operable to split the multi-band upstream signal into a first upstream signal and a second upstream signal (wherein each splitter 14 is operable to split upstream signals of different frequency bands); the second port 12 can be configured to output the first uplink signal to the first RRU 3; the SUL receiving device 15 may be configured to process the second uplink signal, and the third port 13 may be configured to output the processed second uplink signal to the second BBU 4.
It should be noted that, when processing the second uplink signal, the SUL receiving device 15 may complete receiving of the second uplink signal (similar to the receiver function of the RRU), and then transmit the baseband signal to the second BBU4 through the optical fiber for processing, for example, complete the SUL function, and may also complete receiving of the second uplink signal and processing of the SUL baseband signal, and then transmit the processed signal to the second BBU4 through the optical fiber. Preferably, in practical applications, the SUL receiving device 15 may only perform radio frequency signal processing functions similar to those of an RRU receiver, and the baseband functions are all performed in the BBU.
When transmitting downlink, the second port 12 may be configured to receive a downlink signal from the first RRU 3; the at least one splitter 14 may be configured to perform filtering processing on the downlink signal, and filter a spurious signal in the downlink signal to obtain a target downlink signal, where a frequency band of the spurious signal is overlapped with a signal frequency band of the second network; the first port 11 can be used for outputting the target downlink signal to the multi-channel antenna 2, so as to transmit the target downlink signal by using the multi-channel antenna 2. It should be noted that the downlink rf signal of the second network is not associated with the communication device 1 in the embodiment of the present invention, and can be directly transmitted to the corresponding network device through the second BBU4, so as to complete the communication process.
In the embodiment of the invention, the communication equipment comprising the first port, the second port, the third port, at least one shunt and the SUL receiving equipment for supporting the SUL function can realize the shunt transmission of multi-band uplink signals and filter the interference caused by stray downlink signals in the network when the SUL receiving equipment and the RRUs supporting different network frequency bands are deployed at the same station, thereby meeting the requirement of isolation, reusing the communication unit in the existing network such as an antenna and reducing the realization difficulty of a network system; when the communication device in the embodiment of the invention is further applied to different network systems (such as a 4G system and a 5G system) deployed by different vendors, the corresponding communication function can still be realized.
In this embodiment of the present invention, optionally, the uplink signals of multiple frequency bands are uplink signals of an FA frequency band, the first uplink signal is an uplink signal of an F frequency band, and the second uplink signal is an uplink signal of an a frequency band.
For example, referring to fig. 2, assuming that the first network is a TD-LTE network, the second network is a 5G network, the first RRU is an eight-channel RRU supporting the FA frequency band, the second BBU is a 5G BBU, and the multi-band multi-channel antenna is an eight-channel antenna supporting the FA frequency band, then: the communication device 1, that is, the first port 11 of the SUL extension device 1 may be connected to the eight-channel antenna 2 supporting the FA frequency band through 8 radio frequency cables, the second port 12 of the SUL extension device 1 may be connected to the eight-channel RRU3 supporting the FA frequency band through 8 radio frequency cables, and the third port 13 of the SUL extension device 1 may be connected to the 5G BBU4 through an optical fiber. Furthermore, the eight-channel RRU3 supporting the FA frequency band can be connected with the 4G TD-LTE BBU 5 through optical fibers to realize a corresponding 4G communication process; the 5G BBU can be connected to an Active Antenna Unit (AAU) 6 of 64T64R 3.5.5 GHz by an optical fiber to implement a corresponding 5G communication process.
Specifically, when receiving an uplink signal of an FA frequency band (including an uplink signal of an F frequency band and an uplink signal of an a frequency band) from the eight-channel antenna 2 supporting the FA frequency band through the first port 11, the SUL extension device 1 may first divide the uplink signal of the FA frequency band into two uplink signals, which are the uplink signal of the F frequency band and the uplink signal of the a frequency band, through at least one splitter; then, the uplink signal of the F frequency band (i.e. the uplink signal of the TD-LTE system of the single F frequency band) is output to the eight-channel RRU3 for receiving and processing through the second port 12, and the eight-channel RRU3 can convert the radio frequency signal into a baseband signal and then send the baseband signal to the 4G TD-LTE BBU 5 for baseband signal processing; meanwhile, the uplink signal of the a frequency band (i.e., the uplink signal of the 5G system of the single a frequency band) after low-noise amplification is processed by the SUL receiving device, for example, a radio frequency signal is converted into a baseband signal, and the baseband signal is sent to the 5G BBU4 through an optical fiber, so that the subsequent SUL related functions are completed.
When a downlink signal of the F band (i.e., an F band radio frequency signal of the TD-LTE system) is received from the eight-channel RRU3 through the second port 12, the SUL extension device 1 may first perform filtering processing on the downlink signal of the F band through at least one splitter, and filter out a spurious signal of the a band; then, the filtered downlink signal of the F band is output to the eight-channel antenna 2 through the first port 11, so that the downlink signal of the F band is transmitted by using the eight-channel antenna 2. It should be noted that, since the splitter can perform a filtering function, that is, only the downlink signal of the F band can pass through the splitter, and the stray signal of the FA band RRU of the TD-LTE on the a band can be filtered by the splitter, the influence on the SUL receiving performance of the a band deployed in the same station can be avoided, thereby satisfying the requirement of isolation.
It should be noted that, for the downlink signal of the 5G system, the 5G BBU4 may be directly transmitted to the 3.5GHz AAU 6 through the optical fiber (i.e., without being associated with the SUL extension device in the embodiment of the present invention), so as to implement the corresponding 5G downlink communication process.
It is understood that, in practical applications, the connection between the SUL extension apparatus 1 and the eight-channel antenna 2, the eight-channel RRU3, etc. is not limited to 8 radio frequency cables, but may also be two physical cables, for example, in the form of bundled cables.
Referring to fig. 3, an embodiment of the present invention further provides a transmission method, which is applied to the communication device shown in fig. 1, where the method may include the following steps:
step 301: receiving uplink signals of multiple frequency bands from a multi-channel antenna through a first port;

step 303: outputting the first path of uplink signal to the first RRU through the second port;
step 304: and processing the second path of uplink signal through the SUL receiving equipment, and outputting the processed second path of uplink signal to the second BBU through the third port.
Optionally, the uplink signals of multiple frequency bands are uplink signals of an FA frequency band, the first uplink signal is an uplink signal of an F frequency band, and the second uplink signal is an uplink signal of an a frequency band.
Optionally, the first network is a 4G network, and the second network is a 5G network.
Referring to fig. 4, an embodiment of the present invention further provides a transmission method, which is applied to the communication device shown in fig. 1, where the method may include the following steps:
step 401: receiving a downlink signal from the first RRU through the second port;
step 402: filtering the downlink signal through at least one branching unit, and filtering stray signals in the downlink signal to obtain a target downlink signal; the frequency band of the stray signal is overlapped with the signal frequency band of the second network;
step 403: and outputting the target downlink signal to the multi-channel antenna through the first port so as to transmit the target downlink signal by using the multi-channel antenna.
Optionally, the downlink signal includes a downlink signal in an F frequency band and a spurious signal in an a frequency band, and the target downlink signal is the downlink signal in the F frequency band.
