Abstract
The invention relates to the technical field of wireless communication, in particular to a method, a system and equipment for coordinating coexistent interference in equipment. Two schemes such as frequency division multiplexing (FDM) and time division multiplexing (TDM) are performed by coordination. The method for coordinating coexistent interference in equipment comprises the following steps that: a terminal starts a detecting timer which is used for detecting whether a first interference coordinating mode is normal or not; and the terminal determines that the first interference coordinating mode is abnormal under the condition that the terminal does not receive normal interference coordinating executing notification from a network side before the detecting timer is overtime, and transmits auxiliary information of a second interference coordinating mode to the network side for notifying the network side of starting the second interference coordinating mode. As FDM and TDM schemes are performed, the FDM scheme is controlled to avoid interference testing time; the TDM scheme test is instantly performed, and long term evolution (LTE) and industrial scientific and medical (ISM) can better coexist and cooperate.
Description
Technical field

In frequency planning, the adjacent frequency bands (as shown in Figure 1) of the uplink band of a part of TD-LTE frequency range and FD-LTE and ISM, simultaneously a part of LTE frequency range also with the GPS adjacent frequency bands.
1.Band (broadband) 40 (2300MHz-2400MHz) and ISM (e.g.2.4GHz-2.4835GHz for WLAN) are adjacent.
2.Band 7 (2500～2570MHz): FDD UL and ISM are adjacent.
3.Band 13 (777-787MHz, 746-756MHz)/Band 14 (788-798MHz, 758-768MHz) adjacent with GPS frequency range (e.g.1575.42MHz).
When different wireless technology adjacent frequency bands, the transmit operation meeting of a system causes interference to the reception operation of another system.High frequency 20MHz (2380-2400MHz) as LTE band40 can cause strong jamming to ISM, and the low frequency 20MHz (2400-2420MHz) of ISM can cause strong jamming to LTE, and LTEband 7 low frequency 20MHz (2500-2520MHz) can cause strong jamming to ISM.
The interference coordination pattern has collaborative (Coordinated within UE and with network) three kinds in the auxiliary UE of non-collaborative (Uncoordinated mode), UE (terminal) interior collaborative (Coordinated within UE only) and network side in the equipment.Different patterns has different equipment influences and signaling influence.
The coexistence interference coordination can have frequency division multiplexing (FDM) and Time Division Multiplexing both direction in the equipment.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 two kinds of schemes of ISM band; 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.
Under FDM, the LTE system of UE and other wireless systems are operated in non-interfering frequency range, and work separately comprises that scheduling, measurement, switching etc. 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.
How to coordinate to carry out FDM and two kinds of schemes of TDM at present, do not have clear and definite solution.
