One kind measurement and its control method and device
Technical field
The application is related to communication technical field, more particularly to a kind of measurement and its control method and device.
Background technology
With the continuous growth of mobile data services amount, frequency spectrum resource is more and more nervous, only using mandate frequency spectrum
Resource carries out network design and business transmission may can not meet traffic needs, therefore Long Term Evolution
(LTE, Long Term Evolution) system can consider the deployment transmission in unlicensed spectrum resource
(Unlicensed LTE, referred to as U-LTE or LTE-U), to improve Consumer's Experience and spread over.
When LTE is deployed in unlicensed spectrum, its unauthorized carrier wave needs to be used cooperatively with carrier wave is authorized, therefore,
Correlation technique also referred to as authorizes photocarrier method to access (LAA:Licensed Assisted Access).
LBT (listen Before Talk) principles and methods in unlicensed spectrum:
Unlicensed spectrum does not plan specific application system, can for various wireless communication system such as bluetooth,
WiFi etc. shares, using shared unlicensed spectrum resource by way of preempting resources between multiple systems.Therefore
Between the LTE-U of different operators deployment and its compossibility of the wireless communication system such as LTE-U and WiFi is to grind
The emphasis studied carefully and difficult point.3GPP requires the justice for ensureing the wireless communication systems such as LTE-U and WiFi
Coexist, unauthorized frequency range is aided in realizing as secondary carrier by the main carrier for authorizing frequency range.LBT is used as LTE-U
The basic means of contention access, obtain the approval of nearly all company.The essence of LBT technologies is remained
802.11 systems adopt carrier sense/conflict avoidance (CSMA/CA) mechanism, and WiFi system is in unlicensed spectrum
On preempting resources mode it is as shown in Figure 1.Channel is monitored first, when the channel is idle between reach
DIFS (Distributed Inter-Frame Space), just judges that present channel is idle channel, then each etc.
The website of channel to be accessed, just into a random back stage, for avoiding multiple websites in identical
Resource collides.Additionally, in order to guarantee fairness, it further provides that each website can not for a long time take frequency spectrum money
Source, when reaching certain hour or the volume of transmitted data upper limit, needs to discharge resource, so that other equipment/system is robbed
Account for resource.
When LTE works on the carrier wave of unauthorized frequency range, in order to ensure and other equipment or system Fairshare
Frequency spectrum resource, it is also desirable to using LBT mechanism competitive resources.
LAA measurements are described below:
In LAA systems, there is hidden node problem.UE is communicated with website primary nodal point (Node),
But there is website secondary nodal point near UE.For downlink transfer, primary nodal point is to UEUE sending signals
Before, whether can first carry out LBT idle to judge unauthorized carrier channel, but due to website primary nodal point with
Website secondary nodal point is apart from each other, and primary nodal point cannot listen to the signal of secondary nodal point transmission, therefore, i.e.,
Make in secondary nodal point transmission signal, primary nodal point carries out LBT detections can also draw channel in sky
The wrong conclusion of not busy state, therefore primary nodal point can do as usual to UE sending signals, but UE may be because of
The interference of the secondary nodal point near it leads to not normally receive the signal of primary nodal point.In these cases,
For primary nodal point, secondary nodal point is concealed nodes.
In order to detect the concealed nodes in unauthorized frequency range, in LTE system, eNB can be configured and is connected to
The signal intensity that its UE is received indicates (RSSI:Received Signal Strength Indication)
Measurement.The measurement configuration of RSSI includes following parameter:
UE carries out the moment and cycle of rssi measurement;
The report cycle of rssi measurement value;
RSSI threshold values.
UE carries out statistical disposition based on the measured value in the cycle, and to eNB following measurement amount is reported:
Percentage ratios of the RSSI for being measured higher than thresholding;
The meansigma methodss of the RSSI for being measured.
Measurement interval (gap).
In order to realize that the cell between alien frequencies or different system switches, system need to configure UE in certain period of time
Stop the data transmit-receive of work at present frequency range, adjust transceiver and go to measure the channel of alien frequencies or different system cell
Quality, this time period referred to as measures gap.
The pattern that gap is measured in existing LTE system is as follows:
The gap pattern configurations that the UE of table 1 is supported
But, during rssi measurement, the measurement moment of network side configuration may be mutual with current measurement gap
Independent, such as when carrier wave is selected, need UE that carrier wave is measured when Serving cell does not send DRS
RSSI, to obtain the signal intensity that the other equipment being operated on the carrier wave is launched.At this moment UE and net
Network side not only will stop the data transmit-receive of work at present frequency range in measurement gap, and also need in RSSI
The measurement moment also stops the data transmit-receive of work at present frequency range, causes service outage duration long.Assume to survey
The repetition period of amount gap is 40ms, and the cycle of rssi measurement is also 40ms (measurement length is also 6ms),
Now, on the serving cell, the time that UE has 12ms in each 40ms cycle is unable to transceiving data.Such as
Traffic load of the fruit now between UE and network side is heavier, then service outage duration can not be allowed long.
In sum, UE of the prior art carries out caused when LAA is measured interruption excessively.

When UE there are major-minor two sets of rssi measurements to configure, referred to according to L1/L2 signalings (i.e. described notice)
Show, change the rssi measurement configuration of activation, if i.e. UE is being currently used main rssi measurement configuration (this
When the measurement configuration that is configured to be activated of main rssi measurement), then after L2/L1 signalings are received, use auxiliary survey instead
Amount configuration (i.e. the main rssi measurement configuration of deexcitation, activate auxiliary rssi measurement configuration);Vice versa;Survey
The activation and deexcitation of amount configuration, can come into force, it is also possible to receiving after L1/L2 signalings are received
Next rssi measurement cycle after L1/L2 signalings (the rssi measurement cycle is the former rssi measurement cycle,
Be not change after the new rssi measurement cycle, below in the same manner) start time come into force;What is come into force is effective
Property can be extended to the signaling for receiving L1/L2 next time with regard to changing rssi measurement configuration, it is also possible to only exist
In preset duration in (such as one main rssi measurement cycle) effectively;
When UE has a rssi measurement to configure:UE is indicated according to L1/L2 signalings, started or stoped
Rssi measurement (is also believed to the configuration of activation/deactivation rssi measurement);The startup of measurement and stop can be with
Come into force after L1/L2 signalings are received, it is also possible to which the next RSSI after L1/L2 signalings are received is surveyed
The start time in amount cycle comes into force;Its effectiveness can be extended to and receive the instruction of L1/L2 signalings next time,
Can be only effective within a rssi measurement cycle;

Step one:UE sides are received two rssi measurements configuration of eNB configurations and (are believed by RRC (i.e. L3)
Order configuration), including a main rssi measurement configuration and an auxiliary rssi measurement configuration;
Step 2:UE sides L1 carries out rssi measurement according to the configuration of main rssi measurement (to be given tacit consent to when receiving configuration
Main rssi measurement allocation activation), while UE stops receiving at the main rssi measurement configuration corresponding measurement moment
Send out data;
Step 3:UE sides receive L2 or L1 signalings, it is desirable to change the rssi measurement configuration (ratio of activation
As network side thinks that traffic load lightens on UE, the data transmit-receive that can receive the longer time interrupts, and passes through
L2 or L1 signalings, trigger UE sides and adjust current rssi measurement configuration, more preferably closeer so as to obtain
The rssi measurement of collection);
Step 4:The auxiliary rssi measurement configuration of UE sides replaces main rssi measurement configuration to carry out rssi measurement,
That is L1 carries out rssi measurement according to the configuration of auxiliary rssi measurement, while UE is in auxiliary rssi measurement configuration correspondence
The measurement moment stop transceiving data;Auxiliary rssi measurement allocation activation, can be after L1/L2 signalings be received
Come into force, it is also possible to the start time life in the next rssi measurement cycle after L1/L2 signalings are received

Newly can come into force after L1/L2 signalings are received, it is also possible to the next one after L1/L2 signalings are received
The start time in rssi measurement cycle comes into force;
For step 4 and five, another implementation for UE sides receive L2 or L1 require activation or
It is only corresponding in this or next main rssi measurement configuration after the signaling of adjustment rssi measurement configuration
In the rssi measurement cycle, main RSSI is replaced with the configuration of auxiliary rssi measurement when UE sides L1 does rssi measurement
Measurement configuration, remaining continues to main rssi measurement configuration, and this mode requires that main rssi measurement configuration cycle is
The multiple of auxiliary rssi measurement configuration cycle.
In addition, in step 2, default activation mode can not be adopted, but:
UE sides L1 receives L1/L2 signalings, corresponding rssi measurement configuration is activated, according to the RSSI of activation
Measurement configuration carries out corresponding rssi measurement, for example, receive the main rssi measurement of L1/L2 signaling requests activation and match somebody with somebody
Put, then the rssi measurement moment during UE sides L1 is configured according to main rssi measurement carries out corresponding RSSI
Measurement.
Embodiment 2:Directly by L1/L2 signalings, stop/starting corresponding rssi measurement, specifically include:
Step one:UE sides rrc layer receives the rssi measurement moment of eNB configurations and measure the cycle;
Step 2:UE sides L1 carries out rssi measurement according to rssi measurement configuration, while UE is in RSSI
The measurement configuration corresponding measurement moment stops transceiving data;
Step 3:UE sides receive the signaling of L1 or L2, it is desirable to stop current rssi measurement (ratio
As UE traffic loads become weight, the shorter interruption moment is needed, the letter that now eNB passes through L1 or L2
Order stops UE carrying out rssi measurement);UE is edge-on i.e. or in the next rssi measurement cycle to be started to stop
Rssi measurement;
Step 4:UE sides receive the signaling of L1 or L2, and rssi measurement is recovered again.
For step three and four, possible implementation also includes:
UE sides receive L1 or L2 with regard to after the signaling for stopping rssi measurement, stopping measurement only at one
In the rssi measurement cycle effectively, i.e. UE stops RSSI surveys immediately or in the next rssi measurement cycle
Amount, subsequently continues rssi measurement;Or
UE sides are received after L1 or L2 signalings, in follow-up rssi measurement, are surveyed every a RSSI
In the amount cycle, stop rssi measurement, the triggering signaling until being received again by L2 or L1, institute before recovery
The rssi measurement (rssi measurement cycle change that will be original is twice) of configuration.
Above-mentioned stopping/startup also is understood as activating or the rssi measurement configuration in the deexcitation section moment.
In step 2, UE sides L1 receiving the rssi measurement of L3 with postponing, the default activation configuration,
Follow-up rssi measurement configuration according to the activation of L1/L2 signalings or in the deexcitation section moment;Step 2 it is another
A kind of outer possible mode is that UE sides L1 is receiving the rssi measurement of L3 with postponing, and is believed by L1/L2
The configuration of (or activation) rssi measurement is just opened in order, during rssi measurement in being configured according to rssi measurement
Quarter carries out corresponding rssi measurement.
