Background technology
(1) coexistence in the ICO(In-device Coexistence, equipment) introduces
The intelligent terminal market demands that increase rapidly are supported multiple wireless technology simultaneously in an equipment, for example, LTE(Long Term Evolution, Long Term Evolution) and ISM(Industrial Scientific and Medical), LTE and GPS(Global Positioning System, global positioning system) be integrated on the same equipment.Wherein, the former frequency range of distributing to industry, science and medicine that means of ISM, the unauthorized frequency range that is used for scientific research, refer to use the technology of this frequency range at this, comprise WLAN(Wireless Local Area Networks, WLAN (wireless local area network)) and Blue tooth(bluetooth) etc. the typical radio technology on the wireless terminal.
Concrete, in frequency planning, the uplink band of a part of TD-LTE frequency range and FD-LTE and the adjacent frequency bands of ISM, the frequency range schematic diagram that LTE as shown in Figure 1 and ISM are adjacent, a part of LTE frequency range of while also with the GPS adjacent frequency bands.Wherein, Band(frequency range) 40(2300MHz-2400MHz) and ISM(e.g. 2.4GHz-2.4835GHz for WLAN) adjacent; Band 7(2500 ~ 2570MHz), FDD(Frequency Division Duplexing, Frequency Division Duplexing (FDD)) UL(is up) adjacent with ISM; Band 13(777-787 MHz, 746-756 MHz)/Band 14(788-798 MHz, 758-768 MHz) adjacent with GPS frequency range (e.g. 1575.42MHz).
In addition, when different wireless technology adjacent frequency bands, the transmit operation meeting of a system causes interference to the reception operation of another system, the interference schematic diagram of coexistence in the equipment as shown in Figure 2, tight adjacent frequency range, high frequency 20MHz(2380-2400MHz as LTE band40) can cause strong jamming to ISM, the low frequency 20MHz(2400-2420MHz of ISM) can cause strong jamming to LTE, LTE band 7 low frequency 20MHz(2500-2520MHz) can cause strong jamming to ISM.
Non-close frequency range also has Harmonic Interference, for example, if Bluetooth technology is when the low side band transmission, to the leakage power on the TD-LTE frequency band be-50dBm, the TD-LTE received signal power is designed to-70dBm, then before considering that thermal noise and multipath disturb, and the SIR(Signal to Interference Ratio of LTE system, signal-to-jamming ratio) reaches-20dB, obviously can not satisfy transmission requirement.
In order to solve interference problem, the coodination modes that disturbs in the equipment comprises non-collaborative (Uncoordinated mode), UE(User Equipment, subscriber equipment) the auxiliary UE interior collaborative (Coordinated within UE and with network) of collaborative (Coordinated within UE only) and network side in, different patterns has different equipment influences and signaling influence.
In addition, the coexistence interference coordination can have FDM(Frequency Division Multiplexing, frequency division multiplexing in the equipment) and TDM(Time Division Multiplex, time division multiplexing) both direction.FDM is meant LTE adjusted on the mutually non-interfering frequency range with other wireless systems and works, and comprises and adjusts the LTE frequency range and adjust the ISM band dual mode; TDM is meant that LTE system and other system work on interference band in the mode of time-division, has only a wireless system carrying out data transmit-receive in a period of time.
Concrete, under FDM, the LTE system of UE and other wireless systems are operated in non-interfering frequency range, and the scheduling of LTE system, measurement, switching and other wireless system work are independent fully.Under TDM, LTE system and other wireless systems adopt the mode of time-division to work, the period of LTE work is called dispatching cycle (scheduling period) or unlatching cycle (ON duration), and the period of other wireless system work is called the non-dispatching cycle (unscheduled period) of LTE system or closes the cycle (OFF period) or the working clearance (gap).
Under the TDM interference coordination mode, can reach 60 ~ 100ms the non-dispatching cycle of LTE system; For the LTE system, static TDM pattern (be dispatching cycle and non-dispatching cycle length fix) have following problem: UE to detect the link-quality variation, when needing reporting measurement reports to switch, may send measurement report because resource can not be in time obtained in non-dispatching cycle of restriction to trigger; And since non-dispatching cycle of restriction, the eNB(base station) may not in time send switching command to UE, cause the LTE link-quality to worsen, even handoff failure; And because professional variation, original TDM pattern may can not satisfy the time delay and the rate requirement of newly-established LTE business.
(2) ICO TDM introduces
Under the current I CO TDM mode, adopt LTE DRX(Discontinuous Reception, discontinuous reception) mechanism, use the active time(activationary time of LTE DRX) and the non-activationary time of non active time() as dispatching cycle in the TDM scheme and non-dispatching cycle, other technologies on the ISM band are transmitted and the coexistence of LTE system transmissions thereby reach.
Concrete, consider that dispatching cycle and non-dispatching cycle are well-regulated fixedly pattern(patterns in the current TDM business model), in the LTE DRX mechanism, active time is half dynamic pattern, the fixedly pattern(that is subjected to network side configuration is onDurationTimer and DRX cycle), the influence of dynamic data transmission, data re-transmission, transmitting uplink data request (SR and RACH process), therefore current LTE TDM scheme is a kind of DRX mechanism of enhancing.
(3) configuration mode of LTE DRX mechanism
In the existing protocol, DRX mechanism is optional mechanism, promptly by RRC(Radio Resource Control, Radio Resource control) the signaling configuration opens or closes this function, and concrete signaling method is as follows:
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
Because the ICO TDM mechanism DRX mechanism for strengthening, so subscriber equipment can't be distinguished the configuration of traditional LTE DRX mechanism and be used for the configuration of the enhancing DRX mechanism of TDM pattern by current RRC signaling.
