Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a plurality of communication module coexistence methods and communication equipment in the communication equipment.
Background technology
Along with the development of mobile communication technology, adjacent frequency module can occur and coexist as the situation in the communication equipment, adjacent frequency module wherein is meant the module that works in adjacent or near frequency band.Be example with Long Term Evolution (LTE) system below, the adjacent frequency module coexistence method in the communication equipment is introduced.
Fig. 1 is the working frequency range and the ISM band sketch map of LTE system.
As shown in Figure 1, the working frequency range of LTE system (being called for short the LTE frequency range) comprises Band 40 (2300-2400MHz) and Band 7 (2500-2570/2620-2690MHz), and (2400-2483.5MHz) is adjacent with ISM band.
Therefore, if in same communication equipment the existing module that works in the LTE frequency range (being called for short the LTE communication module), the wireless communication module of the ISM band of working in is arranged again, then the interference between these two modules is bigger.Typically; Communication module in the present LTE terminal works in the LTE frequency range; WiFi in this LTE terminal or bluetooth (BT) module (WiFi/BT module) then work in ISM band; Because the antenna isolation very little (about 12dB) between two modules, there are comparatively serious disturbance in the communication module in the LTE terminal and WiFi/BT module, similar LTE communication module and WiFi/BT module be this work between the module (being called for short adjacent frequency module) of different frequency range the coexistence problems ten minutes seriously.
Carry out exemplary illustration in the face of the coexistence problems of adjacent frequency module down:
In the wireless communication system of adjacent work frequently, because two kinds of typical interference will appear in the imperfection of transmitter and receiver usually: the imperfect victim receiver decreased performance that causes of victim receiver decreased performance that transmitter strap external leakage (unwanted emission) causes and receiver band outside inhibitory.Two kinds of interference exist simultaneously.
Usually with terminal loss of sensitivity 3dB as the index that allows maximum spur to disturb, but because extensively there is and the outer spuious index of band relatively poor (adjacent band can only reach-more than the 1GHz of the ITU regulation of 30dBm/MHz general spuious index) in ISM equipment.The transmitting power of supposing WiFi is 15dBm; Stray radiant power in the 2380-2400MHz frequency range is-30dBm/MHz; Be isolated into 15dBi in same terminal between LTE and WiFi antenna; The 2380-2400MHz radiant power that then receives at the LTE terminal antenna is-45dBm/MHz, and make an uproar at the bottom of the receiver of LTE UE power for-92dBm (174+60+13+9), then because WiFi disturbs the quick 47dB of being about that falls that causes; Fall quick criterion considerably beyond common used 3dB, must adopt certain measure just can guarantee the operate as normal of LTE.
Fig. 2 is LTE frequency range and WiFi module frequency range sketch map commonly used.
As shown in Figure 2; The most frequently used channel configuration of WiFi is Channel 1 (CN1); Channel 6 (CN6) and Channel 11 (CN11), the LTE to Band 40 when WiFi uses CN1 disturbs maximum (clutter interference & barrage jamming), wherein; Clutter interference will reduce along with the reduction of LTE operating frequency, but barrage jamming is almost equal at the diverse location of 2300-2400MHz frequency.
During according to LTE communication module and the coexistence of WiFi/BT module; The WiFi/BT module is fallen quick analysis result to the LTE terminal receiver when the different operating frequency; When the WiFi/BT module is operated in CN1; To cause and fall in the 2345-2400MHz scope quickly greater than 50dB, fall quick between 10dB to 50dB in the 2300-2345MHz.If the LTE communication module is worked, will receive very large disturbance in this frequency range.Because the WiFi/BT module selects frequency to be likely at random, if the WiFi/BT module is operated in Channel 1, will cause the LTE communication module in whole frequency by saturated, can't operate as normal.So, must utilize the time domain coordination approach, guarantee that the LTE terminal also can operate as normal under the poorest situation.
At present, existing LTE communication module in the LTE terminal, when the WiFi/BT module is arranged again, adopt following method to make LTE communication module and WiFi/BT module coexist:
The LTE system is LTE communication module configuration uplink and downlink timeslot, and the WiFi/BT module is according to the uplink and downlink timeslot proportioning of LTE module, stops transmission information at the descending time slot of LTE module, and only the ascending time slot in the LTE module sends information.
Yet owing to all descending time slots in the LTE communication module, the WiFi/BT module all can not be sent information, so usage factor of system resource is lower.For example, if two ascending time slots in the 5ms radio frames, three descending time slots, then the WiFi/BT module all can not be sent information in 60% time, with operating efficiency that has a strong impact on the WiFi/BT module and usage factor of system resource.
