Background technology
Along with the growth of business demand, cellular network operator assesses the feasibility using the unlicensed frequency spectrum for LTE system. 3GPP has agreed to start a new research item and studies the access (Licensed-AssistedAccess:LAA) of the license auxiliary using LTE system. LAA is based on carrier aggregation structure, and main plot operates in the frequency spectrum of license, and one or more assisted cell (SCell) operates in unlicensed spectrum and support downlink transmission or support downlink and ul transmissions simultaneously.
With simply use the frequency spectrum permitted the difference is that, the frequency spectrum not receiving license is shared by multiple RAT (such as LAA, Wi-Fi and radar system). This transmits making LAA based on current carrier wave condition with carrying out opportunistic. Specifically, such as European and Japanese in some areas, it is necessary to intercept (LBT:Listen-Before-Talk) rule before following call to reduce the negative effect for the neighbouring system coexisted.
Typically, European Union defines the equipment intercepted before two kinds of calls: the equipment based on frame and the equipment based on load, design parameter is as shown in the table.

Accordingly, because the uncertainty of unauthorized band channels state and dynamic service feature, LAA equipment when communication be often chance and discrete. When not having business unloading demand or channel busy, assisted cell is closed; Otherwise, assisted cell is in running order. From user perspective, switch often very frequent between closed mode and the duty of assisted cell. Therefore, the switching time between two states short for a user is most important, and it can not only promote the experience of user, and can improve the capacity of whole system. 3GPP has been defined for finding reference signal (DiscoveryReferenceSignal:DRS), in order to user carries out time-frequency tracking, information feedback and RRM measurement etc. for closed mode community. Such as, authorizing frequency range, base station is to finding that reference signal was broadcasted with the cycle of 40 milliseconds or 80 milliseconds etc. But, in unauthorized frequency range, due to coexisting of multiple systems, periodic broadcast has become impossible, on the contrary, find that reference signal is only capable of the chance when the channel sense free time and is transmitted. And, if limiting the transmission location finding reference signal, owing to unauthorized frequency range is often occupied by other system, the chance that discovery reference signal will be made to lose transmission, unauthorized frequency range cannot be carried out time-frequency tracking, information feedback and Radio Resource and measure by final utilization family equipment.
