Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a radio frequency processing device, an operation method of the radio frequency processing device, and a communication device. BACKGROUND

[0002] An Upper 6Gigahertz (U6G) base station system adopts a hybrid beam forming (HBF) architecture in the vertical direction. In an enhanced mobile broad band (eMBB) scenario in a dense urban area, the multi-beam time-sharing scanning in the HBF architecture prolongs the channel estimation period, which easily leads to channel aging, and the incomplete spatial information under a single beam restricts the communication capacity in the dense urban area.

[0003] A dispersion architecture uses a Ture Time Delay (TTD) to construct a delay difference, and realizes frequency division multi-beam dispersion. Thus, the target space domain can be continuously covered, and the beam time-sharing scanning process in the HBF architecture is avoided, so as to improve the channel estimation capability and user access opportunity and duration, and thus improve the overall system communication capacity. Since the TTD needs to realize a larger delay amount by a longer winding method, a larger area needs to be occupied, and thus the size of the radio frequency processing device is large. SUMMARY

[0004] Embodiments of the present application provide a radio frequency processing device, an operation method of the radio frequency processing device, and a communication device, which are used to reduce the size of the radio frequency processing device.

[0005] To achieve the above object, embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a radio frequency processing device is provided. The radio frequency processing device includes a multi-stage delay branching structure, the multi-stage delay branching structure including a first end, a plurality of branching structures, a plurality of delay units, and a plurality of second ends. The first end is connected to the plurality of first-stage delay units through the first-stage branching structures respectively. In adjacent two stages of delay units, each delay unit of an upper stage is connected to the plurality of delay units of a lower stage through a corresponding branching structure of the lower stage respectively. Each delay unit of a last stage is connected to a sub-antenna of an antenna array through a corresponding second end. The delay units of the same stage have the same delay amount, and in adjacent two stages of delay units, the delay amount of the delay unit of the upper stage is greater than the delay amount of the delay unit of the lower stage. The radio frequency processing device is configured to control the delay amounts of the plurality of second ends by controlling the switching states of the different delay units.

[0007] In the embodiment, the delay amount of the upper-stage delay device and the delay amount of the lower-stage delay device connected to the upper-stage delay device can be sequentially superimposed in any two adjacent stages of the multi-stage delay branch structure. The radio frequency processing device controls the delay devices to open or close delay, so as to adjust the final delay amount superimposed at the second end. Since the embodiment does not need to set a large number of delay lines in each delay device, the area occupied by the delay device can be greatly reduced, and thus the size of the radio frequency processing device is reduced.

[0008] In some possible embodiments, each branch structure has two branch ends, and the two branch ends are connected with two delay devices respectively. That is, the branch structure adopted in the embodiment is a two-branch structure. In the two delay devices coupled with the two branch ends of the same branch structure one by one, the embodiment can open one of the delay devices and close the other delay device, so as to build delay differences at the multiple second ends of the multi-stage delay branch structure.

[0009] In some possible embodiments, in the two delay devices coupled with the two branch ends of the same branch structure one by one, the radio frequency processing device is configured to: open one of the delay devices, and the delay device outputs the received signal through the delay amount, so as to superimpose the delay amount; close the other delay device, and the delay device outputs the received signal through the minimum delay amount, which can be zero in some examples, so as to not superimpose the delay amount. Thus, delay differences are built at the multiple second ends of the multi-stage delay branch structure.

[0010] In some possible embodiments, in the adjacent two stages of delay devices, the delay amount of the upper-stage delay device is twice the delay amount of the lower-stage delay device. When the embodiment opens one of the delay devices and closes the other delay device in the two delay devices coupled with the two branch ends of the same branch structure one by one, the same delay difference can be obtained between any two adjacent second ends.

[0011] In some possible embodiments, in the adjacent two stages of delay devices, the upper-stage delay device is connected in series with two lower-stage delay devices.

[0012] In some possible embodiments, the delay device includes a delay unit, a minimum delay unit and a gate. The radio frequency processing device is configured to control the gate to select the delay unit, so as to control the delay device to open. Alternatively, the gate is controlled to select the minimum delay unit, so as to control the delay device to close.

[0013] In some possible embodiments, the delay amount of the delay unit or the minimum delay unit to the signal is linearly related to the frequency of the signal. In the embodiment, the frequency-delay response of the delay unit is a straight line, so that the phase difference between the high-frequency signal and the low-frequency signal can be quickly pulled apart, and thus the requirement of the maximum delay amount by the chromatic dispersion architecture is reduced.

[0014] In some possible embodiments, the plurality of delay units are parallel-coupled line delay units. Embodiments of the present application use parallel-coupled line delay units to achieve a frequency-delay response of the delay units as a straight line, and adjust the slope of the straight line by adjusting the coupling degree of the two delay lines in the parallel-coupled line unit.

[0015] In some possible embodiments, there are a plurality of delay units, and the delay amounts of the plurality of delay units are different. The radio frequency processing device is configured to control the gate to select one delay unit from the plurality of delay units, so as to adjust the delay amount of the delay unit. Embodiments of the present application achieve delay amount switching by switching the delay units with different delay amount gears, so as to adjust the expansion angle and the expansion direction of the dispersive beam.

[0016] In a second aspect, an operation method of a radio frequency processing device is provided. The radio frequency processing device includes a multi-stage delay branching structure, and the multi-stage delay branching structure includes a first end, a plurality of branching structures, a plurality of delay units, and a plurality of second ends. The first end is connected to the plurality of first-stage delay units through the first-stage branching structure respectively. In adjacent two stages of delay units, each delay unit of the upper stage is connected to the plurality of delay units of the lower stage through a corresponding branching structure of the lower stage respectively. Each delay unit of the last stage is connected to a sub-antenna of an antenna array through a corresponding second end. The delay units of the same stage have the same delay amount, and the delay amount of the delay unit of the upper stage is greater than the delay amount of the delay unit of the lower stage in adjacent two stages of delay units. The operation method includes: controlling the delay amount of the plurality of second ends by controlling the switching state of different delay units.

[0017] In some possible embodiments, each branching structure has two branching ends, and the two branching ends are connected to two delay units respectively. The operation method specifically includes: in the two delay units coupled to the two branching ends of the same branching structure one by one, turning on one of the delay units, and the delay unit outputs the received signal through the delay amount; and turning off the other delay unit, and the delay unit outputs the received signal through the minimum delay amount.

[0018] In some possible embodiments, the delay amount of the delay unit of the upper stage is twice the delay amount of the delay unit of the lower stage in adjacent two stages of delay units.

[0019] In some possible embodiments, the delay unit includes a delay unit, a minimum delay unit, and a gate. The operation method of controlling the switching state of different delay units includes: controlling the gate to select the delay unit, so as to control the delay unit to be turned on; or controlling the gate to select the minimum delay unit, so as to control the delay unit to be turned off.

[0020] In some possible embodiments, the delay amount of the signal output by the delay unit or the minimum delay unit is linearly related to the frequency of the signal.

[0021] In some possible implementation manners, the delay unit is multiple, and the multiple delay units have different delay amounts. The operation method further includes: adjusting the delay amount of the delay unit by controlling the gate to select one of the multiple delay units.

[0022] In a third aspect, a communication device is provided. The communication device includes a baseband processing device and the radio frequency processing device in the first aspect, and the baseband processing device is connected to the radio frequency processing device.

[0023] In a fourth aspect, a computer readable storage medium is provided. The computer readable storage medium stores computer executable instructions; and the computer executable instructions, when executed, can implement the method in the second aspect.

[0024] The technical effects of the second aspect to the fourth aspect refer to the technical effects of the first aspect and any one of the implementation manners thereof, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] The embodiments of the present application provide a communication device. As shown in Figure 1 The communication device 120 can be connected to the core network device 110 in a wireless or wired manner, and the user terminal 130 (for example, a mobile phone) can be connected to the communication device 120 in a wireless manner. The core network device 110 and the communication device 120 can be independent and different physical devices, or the functions of the core network device 110 and the logical functions of the communication device 120 can be integrated on the same physical device, or a physical device can integrate part of the functions of the core network device 110 and part of the functions of the communication device 120.

[0049] In some embodiments, the communication device 120 can be a base station Node B, an evolved base station eNode B, a base station in a NR mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system, and the embodiments of the present application do not limit the specific device form of the communication device 120. As shown in Figure 2 The communication device 120 can include a baseband processing device (BBU) 200, a radio frequency processing device (RRU) 300, and an antenna array 400. In some embodiments, the radio frequency processing device 300 can be integrated with the antenna array 400, and the radio frequency processing device 300 and the antenna array 400 can be collectively referred to as an active antenna unit (AAU), and the baseband processing device 200 is connected to the active antenna unit. In other embodiments, the radio frequency processing device 300 and the antenna array 400 are two independent devices, the baseband processing device 200 is connected to the radio frequency processing device 300, and the radio frequency processing device 300 is connected to the antenna array 400 through a feeder.

[0050] The communication device 120 provided by the embodiments of the present application can be applied to various communication systems, for example: a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) communication system, a future 5th generation (5G) mobile communication system or a new radio access technology (NR), and three application scenarios of the 5G mobile communication system, i.e., an enhanced mobile broadband (eMBB), an ultra-reliable and low-latency communication (uRLLC), and a massive machine type communication (mMTC), a device-to-device (D2D) communication system, a satellite communication system, an internet of things (IoT), a narrow band internet of things (NB-IoT) system, a global system for mobile communications (GSM), an enhanced data rate for GSM evolution (EDGE), a wideband code division multiple access (WCDMA), a code division multiple access (CDMA), a time division-synchronization code division multiple access (TD-SCDMA). In some examples, the communication device 120 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons and satellites in the air, and the application scenarios of the communication device 120 are not limited by the present application.

[0051] In dense urban enhanced mobile broadband scenarios, in order to improve the communication capacity of the communication system, the communication device 120 can use a dispersion architecture to implement frequency division multi-beam. Figure 3 and Figure 4 As shown in Figure 3 , compared with hybrid beamforming scanning Figure 4 , the dispersion architecture frequency division multi-beam can continuously cover the target space, eliminating the middle beam time scanning process, thereby improving the channel estimation capability and user terminal 130 access opportunity and duration.

[0052] As shown in Figure 5 , the radio frequency processing device 300 using the dispersion architecture can include a plurality of delay lines 311, a plurality of phase shifters 320, and a plurality of amplifiers 330. In some examples, the first end of each of the plurality of delay lines 311 is connected to the first end of the radio frequency processing device 300, the second end of each delay line 311 is connected to the first end of a one-to-one corresponding phase shifter 320, the second end of each phase shifter 320 is connected to the first end of a one-to-one corresponding amplifier 330, and the second end of each of the plurality of amplifiers 330 is connected to a plurality of second ends of the radio frequency processing device 300. The radio frequency processing device 300 uses each delay line 311 (also referred to as a true time delay line) to construct a delay difference, thereby implementing frequency division multi-beam of the dispersion architecture.

[0053] As shown in Figure 6 , in some embodiments, the delay line 311 can include a first switch 510, a second switch 520, and a capacitor 530. The first end of the first switch 510 serves as the first end of the delay line 311. The second end of the first switch 510 is connected to the first end of the second switch 520 and the first end of the capacitor 530, respectively. The second end of the second switch 520 serves as the second end of the delay line 311, and the second end of the capacitor 530 is grounded. The signal can be sampled through the first switch 510 and saved to the capacitor 530, and then output through the second switch 520 after a time τ Δ , thereby realizing the signal delay function. For the delay line 311 shown in Figure 6 , the typical maximum delay is 1500-2000ps, and the typical operating frequency is 0.1-3GHz, which cannot adapt to the target frequency band of the ultra-6GHz base station.

[0054] As shown in Figure 7 , in other embodiments, the delay line 311 can include a plurality of zero delay lines 550, a plurality of strobes 560, and a plurality of delay lines 540 with binary step delay. That is, in the plurality of delay lines 540 shown in Figure 7 , the delay of the first delay line 540 from left to right is τ ΔThe delay of the second delay line 540 is 2τ Δ The delay of the third delay line 540 is 4τ Δ , the delay of the i-th delay line 540 is 2 i-1 τ Δ By switching the gate 560 to connect to the delay line 540, or to connect to the zero delay 311 corresponding to the delay 311, the delay amount of the delay 311 is adjusted so that a delay difference is established between the delays 311. Figure 7 As shown in the delay device 311, each delay device 311 needs to use a large number of delay lines 540 to meet the delay requirement of the dispersion architecture, resulting in a large area occupied by the delay device 311, which in turn makes the size of the RF processing device 300 larger.

[0055] The present application embodiment provides a radio frequency processing device. Figure 8 As shown, the radio frequency processing device 300 includes a multi-stage delay branch structure 310. Figure 9 As shown, the multi-stage delay shunt structure 310 includes a first end, multiple delay devices 311, multiple shunt structures 312, and multiple second ends. In some embodiments, each shunt structure 312 has two shunt ends, that is, the shunt structure 312 is a two-shunt structure, and the two shunt ends are respectively connected to two delay devices 311. This application exemplifies the multi-stage delay shunt structure 310 as a two-stage delay shunt structure.

[0056] like Figure 8 As shown, the first end of the RF processing device 300 is connected to two first-stage delayers 311 respectively through the first-stage branch structure 312. In two adjacent stages of delayers 311 (i.e., the first-stage delayer 311 and the second-stage delayer 311), each delayer 311 of the previous stage (i.e., the first stage) is connected to two delayers 311 of the next stage (i.e., the second stage) through a corresponding branch structure 312 of the next stage (i.e., the second stage). Each delayer 311 of the last stage (i.e., the second stage) is connected to one end of a phase shifter 320 through a corresponding second end, and the other end of the phase shifter 320 is connected to a sub-antenna 410 of the antenna array 400 through an amplifier 330. As described above, in some embodiments, the RF processing device 300 can be integrated with the antenna array 400 to form an active antenna unit.

[0057] In two adjacent stages of delay devices 311, the delay amount of the delay device 311 of the previous stage is greater than the delay amount of the delay device 311 of the next stage. In some embodiments, in two adjacent stages of delay devices 311, the delay amount of the delay device 311 of the previous stage is twice the delay amount of the delay device 311 of the next stage. In addition, the delay amounts of the delay devices 311 of the same stage are the same.Figure 9 In the example provided, the delay amount of the four delay devices 311 in the second stage is τ Δ The delay of the two delay devices 311 in the first stage is 2τ Δ .

[0058] It should be understood that the multi-stage delay shunt structure 310 can also be as follows Figure 10 The three-stage delay branch structure shown in FIG. 3 is a schematic diagram of a multi-stage delay branch structure 310 . The present application does not impose any limitation on the number of stages of the multi-stage delay branch structure 310 .

[0059] In order to ensure that, in two adjacent stages of delay devices 311, the delay amount of the delay device 311 of the previous stage is twice the delay amount of the delay device 311 of the next stage, in some embodiments, the delay device 311 of the previous stage is composed of two delay devices 311 of the next stage connected in series.

[0060] The radio frequency processing device 300 is used to control the switching states of different delay devices 311. Figure 11 As shown, in some embodiments, the delayer 311 includes a delay unit 580, a minimum delay unit 570, and a gate 560. The RF processing device 300 controls the gate 560 to select the delay unit 580 to turn on the delayer 311; or controls the gate 560 to select the minimum delay unit 570 to turn off the delayer 311. In some examples, when the delayer 311 is turned on, the delayer 311 outputs the received signal after the delay amount; when the delayer 311 is turned off, the delayer 311 outputs the received signal after the minimum delay amount; in some examples, the minimum delay amount can be zero. The delay amount of the first-stage delayer 311 and the delay amount of the second-stage delayer 311 in the multi-stage delay structure 310 are superimposed, thereby controlling the delay amount of multiple second ends.

[0061] like Figure 12 As shown, in some embodiments, there are multiple delay units 580, and the delay amounts of the multiple delay units 580 are different. The RF processing device 300 is used to adjust the delay amount of the delay 311 by controlling the gate 560 to select a delay unit 580 from the multiple delay units 580.

[0062] like Figure 13 and Figure 14 As shown, in some embodiments, in the two delay devices 311 coupled to the two branch ends of the same branch structure 312 in a one-to-one correspondence, the RF processing device 300 controls one of the delay devices 311 to be turned on and the other delay device 311 to be turned off, thereby controlling the delay amount between the multiple second ends to have a delay difference. The second ends of the multi-stage delay branch structure 310 are respectively connected to the antenna array 400, as shown in FIG. Figure 13 As shown, in some examples, the four second ends pass through 0, τΔ , 2τ Δ and 3τ Δ Then the received signal is output, so that the dispersion beam is expanded in the first direction. Figure 14 As shown, in other examples, the four second ends pass through 3τ from top to bottom respectively. Δ , 2τ Δ , τ Δ The received signal is output after the sum of 0, so that the dispersion beam is expanded in a second direction opposite to the first direction. In other words, the embodiment of the present application can also control the dispersion beam to expand in a desired direction by controlling the delay amount of multiple second ends.

[0063] like Figure 15 As shown, in other embodiments, in two delay devices 311 coupled one-to-one with two branch ends of the same branch structure 312, the RF processing device 300 controls the two delay devices 311 to be turned on (or off) at the same time, thereby controlling the delay amounts between multiple second ends to be the same (for example, the delay amounts are all zero) to achieve a dispersion-free beam.

[0064] In the embodiment of the present application, in any two adjacent delay devices 311 of the multi-stage delay shunt structure 310, the delay amount of the delay device 311 of the previous stage and the delay amount of the delay device 311 of the next stage connected thereto can be superimposed in sequence. The RF processing device 300 controls each delay device 311 to turn on or off the delay, thereby adjusting the delay amount ultimately superimposed at the second end. Since the embodiment of the present application does not require a large number of delay lines 540 to be set in each delay device 311, the area occupied by the delay device 311 can be greatly reduced, thereby reducing the size of the RF processing device 300.

[0065] In some embodiments, the delay amount of the signal by the delay unit 580 or the minimum delay unit 570 is linearly related to the frequency of the signal. The frequency-delay response of the delay unit 580 is a slant line, which can quickly increase the phase difference between the high-frequency signal and the low-frequency signal, reducing the maximum delay requirement of the dispersion architecture. Figure 16 As shown, in some examples, the multiple delay units 580 are parallel coupled line delay units 580, in which the two delay lines 540 are arranged in parallel. The slope of the frequency-delay response is adjusted by adjusting the coupling degree of the two delay lines 540 (for example, the spacing between the two delay lines 540). In other embodiments, the delay unit 580 can also achieve a frequency-delay response as a slope using other all-pass network structures.

[0066] In some examples, when the dispersion beam needs an opening angle of 27 degrees and the low frequency signal spreads to the left, the embodiments of the present application can construct a delay unit 580 with a delay amount of 152-125 ps (from low frequency to high frequency), and the frequency-delay response of the delay unit 580 is as shown in the curve Figure 17 . The odd mode impedance Ze of the delay unit 580 is 100 ohms, the even mode impedance Zo is 20 ohms, and the physical line length is 89 unit line lengths. For the same dispersion opening angle requirement, the delay unit 311 with a constant frequency-delay response needs to provide a delay difference of 600 ps, and the physical line length is 6 times that of the delay unit 580 of the present application. That is, the embodiments of the present application can greatly reduce the area occupied by the delay unit 311.

[0067] The embodiments of the present application provide an operating method of a radio frequency processing device. The operating method is applied to a radio frequency processing device 300 as shown in Figure 9 , which includes a multi-stage delay branching structure 310, the multi-stage delay branching structure 310 including a first end, a plurality of branching structures 312, a plurality of delay units 311, and a plurality of second ends. Each branching structure 312 is a two-branch structure and has two branching ends. The first end is connected to two first-stage delay units 311 through a first-stage branching structure 312, respectively. In adjacent two-stage delay units 311, each delay unit 311 of an upper stage is connected to two delay units 311 of a lower stage through a corresponding branching structure 312 of the lower stage, respectively. Each delay unit 311 of a last stage is connected to a sub-antenna 410 of an antenna array 400 through a corresponding second end. The delay units 311 of the same stage have the same delay amount, and the delay amount of a delay unit 311 of an upper stage is twice the delay amount of a delay unit 311 of a lower stage in adjacent two-stage delay units 311.

[0068] The radio frequency processing device 300 controls the delay amount of the plurality of second ends by controlling the switching state of the different delay units 311. As shown in Figure 18 , the operating method includes steps S110-S120, as follows:

[0069] S110, in the two delay units coupled one-to-one with the two branching ends of the same branching structure, one of the two delay units is turned on.

[0070] In some embodiments, the delay unit 311 includes a delay unit 580, a minimum delay unit 570, and a gate 560. The embodiments of the present application control the gate 560 to select the delay unit 580, control the delay unit 311 to be turned on, and make the delay unit 311 output the received signal through the delay amount.

[0071] S120, in the two delay units coupled one-to-one with the two branching ends of the same branching structure, the other of the two delay units is turned off.

[0072] In some embodiments, the minimum delay unit 570 is selected by the gate 560, and the delay 311 is controlled to be closed, so that the delay 311 outputs the received signal with a minimum delay.
