Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and apparatus avoiding mutual interference in terminal.
Background technology
Along with the development of intelligent terminal technology, support multiple wireless technology in a terminal equipment simultaneously, such as, support LTE (Long Term Evolution simultaneously, Long Term Evolution) and ISM (Industrial Scientificand Medical, industrial scientific medical) technology, or support LTE and GPS (GlobalPositioning System, global positioning system) technology simultaneously.Wherein, ISM band refers to the frequency range distributing to industry, science and medicine, namely, for the unauthorized frequency range of scientific research, the technology of this frequency range is used to comprise typical wireless techniques on the wireless terminals such as WLAN (Wireless Local Area Network, WLAN (wireless local area network)) and Blue tooth (bluetooth).
In frequency planning, part TD (Time Division, time-division)-LTE frequency range and FD (Frequency Division, frequency division) uplink band of-LTE is adjacent with ISM band, as shown in Figure 1, Band 40 (2300MHz-2400MHz) is adjacent with ISM band (2.4GHz-2.4835GHz), the Band7 (2500 ~ 2570MHz) being applicable to FDD UL (Frequency Division Duplex Uplink, time division multiplexing up link) is also adjacent with ISM band.Meanwhile, a part of LTE frequency range also with GPS adjacent frequency bands, such as, Band 13 (777-787MHz, 746-756MHz)/Band 14 (788-798MHz, 758-768MHz) is adjacent with GPS frequency range (such as, 1575.42MHz).
When the adjacent frequency bands of different wireless technologys, the transmit operation of a system can cause interference to the reception operation of another system, as shown in Figure 2.Closely adjacent frequency range, high frequency 30MHz (2370-2400MHz) as LTE Band40 can cause strong jamming to ISM band, the low frequency 20MHz (2400-2420MHz) of ISM can cause strong jamming to LTE frequency range, and the low frequency 20MHz (2500-2520MHz) of LTE Band 7 can cause strong jamming to ISM band.Such as, when Bluetooth technology is in low side band transmission, be-50dBm to the leakage power on TD-LTE frequency band, TD-LTE received signal power is designed to-70dBm, before consideration thermal noise and multi-path jamming, the SIR (Signal-to-interference, signal interference ratio) of LTE system reaches-20dB, obviously can not meet transmission requirement.
In LTE system, terminal, when channel quality declines, can carry out switching or adjudicate RLF (Radio Link Failure, Radio Link Failure), thus trigger the process of RRC (Radio Resource Control, wireless heterogeneous networks) connection reconstruction.
Wherein, handoff procedure comprises base station measurement configuration, terminal measurement report, base station initiation switching and the terminal switch a series of processes to adjacent cell, and after handoff failure, terminal can only carry out RRC connection reconstruction, thus is reliably connected with selected cell recovery.
In addition, Radio Link Failure is the autonomous behavior of terminal, is applicable to terminal and can not carries out the application scenarios of normal information transmission with base station.The mode determination channel quality degrades can monitored by wireless link, thus determine Radio Link Failure, trigger RRC connection reconstruction process, make terminal re-establish reliable connection with selected community.As shown in Figure 3.Wherein, the first stage is the Radio Link Failure judgement stage, and second stage is the RRC connection reconstruction stage.
T310 in Fig. 3 indicates relevant to physical layer synchronization " in-sync " and step-out " out-of-sync ", its specific rules is: when terminal receives N310 " out-of-sync " instruction of sending from bottom continuously and now T300, T301, T304 and T311 timer is invalid, then start timer T310; At T310 run duration, receive N311 " in-sync " instruction from bottom continuously, then terminal stops timer T310; If T310 is overtime, then judge Radio Link Failure.
Correspondingly, terminal physical layer needs to detect quality of down wireless link, to judge whether to need to send out " out-of-sync "/" in-sync " instruction to high level, its measuring object is CRS (Cell-Specific ReferenceSignal, cell reference signals).For non-DRX (Discontinuous Receive, discontinuous reception) pattern, the every radio frames of physical layer (10ms) assessment (assess) radio link quality, according to the magnitude relationship between the result of calculation of assessment cycle (evaluation period) interior radio link quality and thresholding, determine whether to send instruction to high level.If result of calculation is less than Qout, then send step-out instruction out-of-sync; If result of calculation is greater than Qin, then sends and synchronously indicate in-sync.The assessment cycle of step-out instruction correspondence is 200ms, and the assessment cycle of synchronous instruction correspondence is 100ms.
For DRX mode, the at least each DRX cycle of physical layer assesses a radio link quality, according to the magnitude relationship between the result of calculation of assessment cycle (evaluation period) interior radio link quality and thresholding, determine whether to send instruction to high level.If result of calculation is less than Qout, then send step-out instruction out-of-sync; If result of calculation is greater than Qin, then sends and synchronously indicate in-sync.Assessment cycle (T
evaluate_q
out_DRX) and (T
evaluate_q
in_DRX), as shown in table 1.
Assessment cycle table under table 1DRX pattern
Wherein, thresholding Qout and Qin is defined as respectively based under the Parameter Conditions such as the specific bandwidth specified in agreement 36.133, and the BER (Block Error Rate, Block Error Rate) that quality of down wireless link is corresponding is higher than 10% with lower than 2%.Qout and Qin is not the value of configuration, but a kind of stable statistics.
Inventor is realizing in process of the present invention, and at least there are the following problems to find prior art:
Handoff procedure is the Scenario Design for channel quality gradual change, and time delay is comparatively large, and signalling interactive process is more.For the scene of mutual interference in equipment, can not trigger measurement in time and report, and due to the strongly disturbing appearance that happens suddenly, base station and the mutual signaling of terminal room probably can not accurately be transmitted.Therefore, be insecure by the problem of the mutual interference in handoff procedure solution equipment.
Because terminal has the possibility recovering link-quality after of short duration channel degradation, therefore, the cycle of Radio Link Failure judgement is longer.But for the scene of mutual interference in equipment, long Radio Link Failure judgement can cause unnecessary Transmission, and causes the loss of data.
