Description
Technical field
The present invention relates to wireless communication techniques, and in particular, to for passing among the communication equipment of wireless communication system
Discovery reference signal (the Discovery Reference Signal in frequency range that defeated and reception is not permitted
Unlicensed Band:U-DRS) method and apparatus.
Background technique
With the growth of business demand, cellular network operator is being assessed using the unlicensed frequency spectrum for LTE system
Feasibility.3GPP has agreed to one new research item of starting to study the access of the license auxiliary using LTE system
(Licensed-Assisted Access:LAA).LAA is based on carrier wave paradigmatic structure, and main plot operates in the frequency spectrum of license, and one
A or multiple supplementary cells (SCell) operate in unlicensed spectrum and support downlink transmission or support downlink chain simultaneously
Road and uplink transmission.
From the frequency spectrum of not receiving license unlike the frequency spectrum permitted is only used only by multiple RAT (such as LAA, Wi-Fi
And radar system) share.This transmits LAA with carrying out opportunistic based on current carrier wave condition.Specifically, one
(LBT:Listen-Before-Talk) rule is listened to reduce pair in a little areas such as Europe and Japan before needing to follow call
In the negative effect of the system nearby coexisted.
Typically, European Union defines the equipment listened to before two kinds of calls: the equipment based on frame and the equipment based on load,
Design parameter is as shown in the table.
Table 1: the parameter list of the equipment based on frame and the equipment based on load
Therefore, because the uncertainty of unauthorized band channels state and dynamic service feature, LAA equipment is in communication
Often chance and it is discrete.When not having business unloading demand or busy channel, supplementary cell is in close state；
Conversely, supplementary cell is in running order.For user perspective, switch between the closed state and working condition of supplementary cell
Often very frequently.Therefore, the switching time for a user between short two states is most important, can not only be promoted
The experience of user, and can be improved the capacity of whole system.Discovery reference signal (Discovery has been defined in 3GPP
Reference Signal:DRS), so as to user for closed state cell carry out time-frequency tracking, information feedback and
Wireless resource management measurement etc..For example, base station is to discovery reference signal with 40 milliseconds or 80 milliseconds etc. of week in authorized spectrum band
Phase is broadcasted.However, due to coexisting for multiple systems, periodic broadcast has become impossible, on the contrary in unauthorized frequency range
Ground, discovery reference signal are only capable of will do it transmission on channel sense idle opportunity.Moreover, if limiting the biography of discovery reference signal
Defeated position will make the chance for finding that reference signal loses transmission, finally make since unauthorized frequency range is often occupied by other systems
User equipment can not carry out time-frequency tracking, information feedback and radio resource measurement to unauthorized frequency range.Therefore, non-
Authorized spectrum band design is a set of flexible and effectively finding reference signal mechanism is particularly important.
Summary of the invention
Therefore, according to it is above-mentioned to background technique and understanding, consider LBT require in the case where
Come notifying user equipment listens to discovery reference in the corresponding frequency range that do not permitted at which at moment on which carrier wave
Signal is very important.It is intended for configuring at least one in the communication equipment of wireless communication system the invention proposes a kind of
