The schematic diagram that can be implemented within the example communication network 100 of embodiment of the disclosure is shown in FIG. 1.It is logical
Communication network 100 may include one or more network equipment 101.For example, in this example, the network equipment 101 can embody
For base station, for example, the node B (eNB) or 5GNB (also known as gNB) of node B (NB), evolution.It should be understood that the network
Equipment 101 can also be presented as repeater or RRU etc..The network equipment 101 is multiple terminals within its coverage area
Equipment 111-1,111-2 and 111-3 (hereafter referred to collectively as terminal device 111) provide wireless connection.From the network equipment 101 to terminal
The transmission of equipment 111 can be referred to as downlink (DL) transmission, and the transmission in opposite direction is referred to as uplink (UL) chain
Road transmission.
In wireless communication system 100 in Fig. 1, an important parameter of the performance for characterizing the network equipment 101 is
VSWR.The efficiency of transmission of the value instruction network equipment 101 of the parameter.
Currently, being usually all during communicating downlink business no matter for frequency division duplex (FDD) or TDD system
The detected value of VSWR is obtained by the feedback path of transmitter in the network equipment 101.However, the inventor of the disclosure realizes
Arrive, during communicating downlink business execute VSWR detection normal downlink traffic may be had adverse effect on or
Person's limitation.In addition, this traditional VSWR detection method is some logical due to the application of FDD system and TDD system beam forming
The VSWR detection accuracy that will lead to the network equipment in letter scene reduces, and triggers the VSWR alarm of mistake.
For example, more and more Carrier Requirements are set using the network with beam forming (BF) function in a communications system
Standby (for example, RRU).However, depending on beamforming factor/weight configuration and aerial array under certain Client application scenes
Isolation performance, the VSWR detection accuracy of the network equipment can reduce, and trigger false VSWR alarm, and make operator mistakenly
The network equipment is returned into equipment vendor.
Specifically, for the network equipment (such as RRU), if the BF factor for enabling BF function, and configuring/
Weight changes between 0.2 to 1, then the output power in different channels may have the difference up to 14dB in RRU.Below in Fig. 2
Show with 8 channels and for TDD RRU200 of every channel with the transmission power (being expressed as 8x20W) of 43dBm for
It is bright.In the RRU 200, the data from Base Band Unit (BBU) 201 by the 1-8 of channel one or more is processed,
And it is launched away via aerial array 202.If the channel 1 in RRU200 is configured for the BF factor/weight that value is 0.2,
Channel 2 is configured for the BF factor that value is 1, then in this case, the output power in channel 2 is 20W (43dBm), and channel 1
Output power is only 794mW (29dBm).Therefore, the transmission power in channel 1 and the transmission power in channel 2 have the difference of 14dB.
In this case, if the main alarming threshold of VSWR is arranged to 1.9 (being equivalent to 10dB), and typical antenna
Isolation is 20dB, then the VSWR alarm in channel 1 may be triggered falsely.This is because the jamming power from channel 2 is
23dBm, it is only 6dB lower than the output power in channel 1, cause the VSWR in channel 1 to be detected as lower than main alarming threshold.
For following 5G RRU for example with up to 64 or 128 channels, send that power is unbalanced to be caused
Interference may be more serious, therefore VSWR detect the case where may be even worse.
A kind of possible scheme for solving the above problems is to reduce interference by improving the isolation of interchannel.So
And it is limited to the size of the network equipment, the isolation for improving interchannel is difficult.It is set in addition, will increase to improve isolation
Standby manufacturer and the investment with operator.Moreover, for the network equipment with a large amount of channels, especially for i.e.
For the network equipment of extensive multiple-input and multiple-output (mMIMO) type of arrival, the difficulty of the solution is bigger.
Embodiment of the disclosure proposes the new solution for VSWR detection.It, can using embodiment of the disclosure
To improve VSWR detection accuracy, and therefore reduce or avoid the VSWR alarm of mistake and the equipment of mistake to return.In addition, should
Solution does not need the additional investment of operator.
Some embodiments of the present disclosure propose from the period of transmitting downlink traffic to change VSWR detection to all logical
Road is in the period for being used to send BF calibration of transmission equal-wattage level signal, to reduce from the other of big transmission power
The interference in channel.No matter VSWR detection accuracy can be improved in the BF factor of operator's configuration, embodiment of the disclosure.
In some embodiments, the VSWR detection method proposed in the disclosure can effectively ensure that the RRU with BF function
VSWR detection accuracy, it might even be possible to relax to reach with the channel separation of the comparable VSWR precision of tradition VSWR detection scheme
It is required that.
The VSWR detection scheme herein proposed is especially suitable for needing more inexpensive and smaller size of support multichannel
RRU, such as support the 5G RRU in 64 or more channels.However, it is to be appreciated that embodiment of the disclosure is not limited to this specific
The network equipment in use, but other network equipments and communication scenes there are similar problems can be used for.
Fig. 3 shows the flow chart of exemplary method 300 according to an embodiment of the present disclosure.The exemplary method for example can be by scheming
The network equipment 101 in cordless communication network 100 in 1 is implemented.However the disclosure is not limited to this.Only for the purposes of begging for
By describing method 300 below with reference to network environment 100 described in the network equipment 101 and Fig. 1.
As shown in figure 3, the network equipment 101 determines the period for sending BF calibration for the network equipment in block 310.
In the period, the network equipment 101 sends signal by multiple sendaisles (for example, with identical transmission power).
In one embodiment, TDD system can be located at for period for sending BF calibration of the network equipment 101
Protective time slot (GP) in special subframe.The signal of the frame structure 400 of TDD long term evolution (LTE) system is shown in FIG. 4
Figure.As shown in figure 4, within the system, a radio frame length 10ms, the field for being 5ms including two length.10ms's
Radio frame is divided into 10 subframes, i.e. subframe 0 arrives subframe 9.Each subframe includes time slot 0 and time slot 1.According to tdd frame knot
The different configurations of the DL/UL of structure, each subframe can be correspondingly configured to the downlink subframe for downlink traffic, use
In the uplink subframe or special subframe of uplink service.In the example of fig. 4, subframe 1 and 6 is special subframe.It should
Special subframe includes for the descending pilot frequency time slot (DwPTS) of downlink transmission, for the ascending pilot frequency of uplink transmission
Time slot (UpPTS) and GP.
Under normal conditions, there is no uplink or downlink transmission in GP.However in accordance with an embodiment of the present disclosure,
It can be executed in GP and send BF calibration.In the period for sending BF calibration in GP, the network equipment 101 passes through multiple
Sendaisle sends signal.In some embodiments, the network equipment 101 is sent out by multiple sendaisles with identical transmission power
The number of delivering letters.The schematic diagram for carrying out sending BF calibration during GP is shown in FIG. 5.
BF calibration is sent as shown in figure 5, can execute in multiple time intervals 510 and 520.In some embodiments,
The calibration is to execute in the period.In the example of hgure 5, time interval 510 and 520 can be one in radio frame respectively
TDD special subframe or part of it.As shown in figure 5, include DwPTS 501 and GP 502 in time interval 510 and 520, and
It and include the period 530 calibrated for sending BF in GP 502.In the period 530, the network equipment 101 passes through multiple
Sendaisle (such as with identical transmission power) sends calibration signal.
In some embodiments, it is configurable for sending the period 530 of BF calibration.As example rather than limit
System, the period 530 can be configured by parameters such as vertical shift, field instructions.In further embodiments, in GP 502
It executes in the case where sending BF calibration, predetermined time period 540 can be reserved in GP 502 before calibration, cut for calibrating
It changes.
It should be understood that the present disclosure is not limited to send BF calibration with any specific implementation to execute.Namely
It says, transmission BF calibration can be executed using any of or exploitation in the future method.
It now continues with reference to Fig. 3.In block 320, the network equipment 101 is identified for sending the period of BF calibration
The VSWR of multiple sendaisles of the detection network equipment 101 in (such as period 530 in Fig. 5).
Believe since in the period 530, the network equipment 101 is sent from each channel (such as 8 channels in Fig. 2)
Number, therefore interfere the problem of increasing to be avoided caused by the different BF factors as configuring.This makes dry from other channels
Reduction is disturbed, and the detection accuracy of VSWR is improved.
The exemplary operations 600 that can be executed in the block 320 of Fig. 3 are shown in FIG. 6.As shown in fig. 6, in block 610, net
Network equipment 101, which can be determined, to be carried out sending the school BF in the period (such as period 530 in Fig. 5) for sending BF calibration
Quasi- initial time (such as starting point 531 in Fig. 5)；And in block 620, from the initial time VSWR detect.
For example, the switching that the network equipment can be configured to VSWR detection according to the starting point for sending BF calibration switchs, so that VSWR
The trigger point of detection is located at the starting point of TX beam forming calibration.That is, the network equipment 101 can be existed by switch block
The path for VSWR detection is connected at the initial time and starts VSWR detection.
Alternatively, or additionally, can by according to send BF calibration timing adjustment for VSWR detection timing come
So that detecting the VSWR of multiple sendaisles of the network equipment 101 in the period for sending BF calibration.
The timing diagram for realizing VSWR detection between sending beam forming alignment epoch is schematically shown in Fig. 7.
In the figure, logically high to mean to enable, and logic low means to disable.As seen from Figure 7, during the period 701, transmission unit
Dividing enable signal level is height, i.e., sendaisle is activated, and the baseband board of the network equipment transmits the useful signal in all channels.And
And during the period 702, the enable signal level of a receiving channel for sending BF calibration is also high, that is, the reception
Channel is activated, and enables to receive signal during the period 702.Thereby, it is possible to the weights in time interval 701 and 702
It is executed during closing part (such as during the time interval 703 in Fig. 7) and sends BF calibration operation.
It is calibrated in this example it is assumed that the network equipment 101 is sent in the period 713 in time interval 703 for BF
Signal.It, can be configured with the time for calibrating switching before the signal that the network equipment 101 sends for sending BF calibration
Section 704.In addition, in this example, as shown in fig. 7, the enable signal level during the period 705, for VSWR detection
For height, it is meant that, the network equipment 101 can execute VSWR detection during the period.In some embodiments of the present disclosure,
The network equipment 101 can be enabled in transmitting portion enable signal, VSWR switching switch and for sending the receiving portion that BF is calibrated
Signal is that VSWR detection is executed in the high period.For example, the network equipment 101 can be in the period for sending BF calibration
VSWR detection is executed during 713.
At the moment 706, transmission/reception switching signal level of TDD becomes high, while receiving portion enable signal also becomes
High level, that is, the network equipment 101 is switched to reception state.This means that the network equipment 101 can after executing VSWR detection
Operation is received to execute during UpPTS.
Embodiment of the disclosure is not limited to realize timing control as shown in Figure 7 in any particular manner.As example
Rather than limit, timing as shown in Figure 7 can be realized by the switch of control respective paths.It should be understood that the disclosure is unlimited
Specific switch arrangement in each path.
In some embodiments, the network equipment 101 may be configured to the sampling parameters of VSWR detection (for example, modification net
The register value of digital pre-distortion (DPD) output and feedback power meter in network equipment 101), to guarantee having enough sampling numbers
Mesh is detected for VSWR.Sample length for VSWR detection can be different from linearly excellent for the power amplifier in the network equipment 101
Number is sampled when change used in DPD.In some embodiments, it can be less than or equal to for the sample length of VSWR detection and be used for
Send sample length (such as period 713 in the sample length or Fig. 7 in the period 530 in Fig. 5 of calibration signal
In sample length).
As an example, showing the operation example 800 for VSWR detection that can be executed by the network equipment 101 in Fig. 8.
The operation 800 can execute in the block 320 of Fig. 3.As shown in figure 8, the network equipment 101, which can determine, to be used in block 810
It sends for sending the sampling number of BF calibration in the period of BF calibration, and is less than in 820 use of block or is taken equal to this
The sample of signal of sample number executes VSWR detection.
As an example, not a limit, in some embodiments, the network equipment 101 can be in the time for sending BF calibration
It is detected in a manner of the time-division in section (such as the period 530 in Fig. 5 or sample length in the period in Fig. 7 713) more
The VSWR of each sendaisle in a sendaisle.For each channel VSWR detection can according to existing method into
Row, embodiment of the disclosure are not limited to any specific detection algorithm.Only as an example, in some embodiments, in the block of Fig. 3
320, the network equipment 101 can measure the signal of the signal power and reflection that send by the sendaisle in multiple sendaisles
Power, and detect based on the measurement VSWR of the sendaisle in multiple sendaisles.
In illustrative and not limiting purpose, a channel in the network equipment is shown schematically in Fig. 9
The example signal figure of VSWR detection.It should be understood that component shown in figure and signal are merely illustrative, in other embodiments,
VSWR detection can be related to less or more or different component and signal.
In the example of figure 9, it sends signal 901 and passes through digital pre-distortion (DPD) 910, digital analog converter (DAC) 920, function
The transmitting path that rate amplifier (PA) 930, coupler 940, circulator 950 and filter 960 form is sent out from antenna 970
It goes.Meanwhile the signal returned from antenna-reflected enters VSWR through wave filter 960, circulator 950 and detects path.Into VSWR
The return signal 902 for detecting path receives analog-digital converter (PDRX by digital pre-distortion under the control of switch 980 and 981
ADC) 990 and digital pre-distortion receiver (PDRX) 991.Available signal power 905 is sampled at the output of PDRX 991
(to simplify description, being denoted herein as Ppdrx), the input for sending DPD sample available signal power 903 (for
Simplify description, be denoted herein as Pdpdin), and available signal power 904 is sampled (for letter at the output of DPD
Change description, be denoted herein as Pdpdout).This can be determined based on the measurement of the power to signal 903,904 and 905
The VSWR in channel.
For example, forward signal power P1 and reverse signal power P2 can be obtained by following (1) and (2) formula respectively:
