Description
Technical field
The present invention relates to fields of communication technology, in particular to a kind of industry of LTE system in unauthorized band operation
Service detection system, a kind of terminal and a kind of base station of the detection method, a kind of LTE system of being engaged in unauthorized band operation.
Background technique
Currently, the capacity of the existing wireless frequency spectrum for distributing to mobile service is with the fast development of mobile service
It is unable to satisfy requirement.In 3GPP (The 3rdGeneration Partnership Project, 3G (Third Generation) Moblie partner
With tissue) the Rel-13 stage, the mechanism of one kind referred to as LAA (Licensed Assisted Access, the access technology of auxiliary)
It is introduced into.In LAA mechanism, the transmission of mobile communication can carry in unlicensed spectrum, such as the frequency range of 5GHz.These are non-
Frequency spectrum is authorized, the systems such as presently mainly WIFI, bluetooth, radar, medical treatment are using.
Due to the diversity and complexity of system in unlicensed spectrum, directly LTE (Long Term Evolution, length
Phase evolution) mechanism for being the stability that not can guarantee the safety and connection of user in unlicensed spectrum.Therefore, exist
It is unauthorized to help using authorization frequency spectrum by CA (Carrier Aggregation, carrier wave polymerization) mechanism in the mechanism of LAA
Access on frequency spectrum.Currently, using LTE there are two types of working method in unlicensed spectrum, one is supplement downlink (SDL,
Supplemental Downlink), i.e. only downlink transfer subframe；Another kind is tdd mode, both includes downlink transfer subframe,
It also include uplink subframe, as shown in Figure 1.
In unlicensed spectrum, need to compete between multiple systems using resource, in order to guarantee the Fairshare between system, one
The mechanism (LBT, Listen Before Talk) that kind is known as " listem-before-talk " is introduced into.That is competition uses resource
Whether system needs monitor channel occupied by other system before busy channel.If channel is the free time,
So the system can remove busy channel.If channel is busy, which can not busy channel.Currently, LBT machine
System there are two types of, one is FBE (Frame based equipment, the equipment based on frame structure), and one is LBE (Load
Based equipment, the equipment based on load).In the case where FBE, whether needing to carry out channel idle by predetermined period
Detection；In the case where LBE, detection whether channel idle can be initiated at any time according to the demand of business.
Currently, the energy conservation of terminal becomes a urgent problem to be solved.In view of at small cell (small base station)
Scene under, since the switch state of small cell more may frequently change, serviced by small cell
Terminal if being constantly in connection status, need to go the transmission of detection data in each frame, thus can bring higher
Energy consumption.
To solve the above problems, the scheme of some terminal detections is proposed, for example, can depositing by detection pilot signal
Whether judge whether terminal needs to do Data Detection on the frame, however, in unlicensed spectrum, especially LBE's
In the case of, pilot signal presence or absence depends on Channel Detection success on which position, i.e., when detect channel idle, because
This, may will affect the accuracy that terminal carries out Data Detection；Alternatively, can be notified by serving BS via physical layer signaling
The sub-frame set that the terminal serving BS is opened, however can not equally be applied in unauthorized frequency range under this method, equally
Also in that base station can not learn whether Channel Detection can succeed.
Therefore, it is necessary to a kind of methods that the wake-up terminal applied to unauthorized frequency range is detected, effectively to avoid end
Dispatcher meeting is missed at end, and avoids consuming more energy, reaches energy-efficient purpose.
Summary of the invention
The present invention is based on the above problems, proposes a kind of new technical solution, in the LBT mechanism for having used LBE,
The energy consumption that terminal can be effectively reduced can accurately know that base station successfully occupies while reaching energy-efficient purpose
The position of channel, so that being effectively prevented from terminal misses dispatcher meeting.
In view of this, the first aspect of the present invention proposes a kind of business inspection of LTE system in unauthorized band operation
Survey method is used for terminal, comprising: receives the instruction information from the base station for providing service for the terminal；According to the instruction
It whether there is target detection signal at least one aiming symbol of the current subframe of unauthorized frequency range described in infomation detection, with true
Recognize whether the base station has occupied idle channel；When detecting the target detection signal, confirm that the base station has occupied
To idle channel, so that the base station executes traffic scheduling in the unauthorized frequency range.
In the technical scheme, by according to the instruction information from the base station for providing service for terminal received, inspection
Survey with the presence or absence of target detection signal at least one aiming symbol of the current subframe of unauthorized frequency range, whether to confirm base station
Idle channel has been occupied, if detecting target detection signal, has illustrated that base station has occupied idle channel, can have been awarded non-
Traffic scheduling is executed in power frequency range, in the present solution, do not need to detect entire subframe, and is only to prenotice
It is detected on aiming symbol (for example, the 1st of current subframe the, 5 and 11 symbol), in this way, terminal can be effectively reduced
Energy consumption can accurately know the position of base station success busy channel, thus effectively while reaching energy-efficient purpose
Ground avoids terminal from missing dispatcher meeting.
