Description

The method for parameter configuration and device of discontinuous reception modes

Technical field

The present invention relates to radio network technique fields, in particular to a kind of parameter configuration of discontinuous reception modes The parameter configuration device of method and a kind of discontinuous reception modes.

Background technology

The core of existing network is with the sharp increase of message volume, 3GPP authorizes frequency spectrum to seem less and less adequate To provide higher network capacity.In order to further increase the utilization of frequency spectrum resource, 3GPP is just discussing how to authorize frequency spectrum Unlicensed spectrum is used under helping, such as 2.4GHz and 5GHz frequency ranges.These unlicensed spectrums are presently mainly WiFi, bluetooth, thunder It reaches, the systems such as medical treatment are using.In general, it is the access technology of authorized spectrum band design, such as LTE (Long Term Evolution, the long term evolution of universal mobile communications technology) be not suitable for using in unauthorized frequency range, because of this kind of accesses of LTE The requirement that technology optimizes spectrum efficiency and user experience is very high.However, carrier wave polymerizable functional allow LTE is deployed in it is unauthorized Frequency range becomes possible to.3GPP proposes the concept of LAA (interventional technique of LTE Assisted Access, LTE auxiliary), by LTE authorizes the help of frequency spectrum to use unlicensed spectrum.And unlicensed spectrum can there are two types of working methods, as shown in Figure 1A, One is supplement downlink SDL (Supplemental Downlink, supplement downlink), i.e. only downlink transfer subframe;Such as Figure 1B institutes Show, another kind is TDD (Time Division Duplex, time division duplex) pattern, and downstream transmission subframe all includes.Under supplement Row such case can only be used by carrier aggregation technology.And tdd mode can make by DC (Dual Connectivity) With can also independently use.Compared to WiFi, the LTE for being operated in unauthorized frequency range has the ability to provide higher spectrum efficiency and more Big coverage effect, while allowing data traffic between authorized spectrum band and unauthorized frequency range without seaming and cutting based on the same core net It changes.For users, it means that better broadband experience, higher rate, better stability and mobile convenience.

The existing access technology used in unlicensed spectrum, such as WiFi have weaker anti-interference ability.In order to keep away Exempt to interfere, WiFi system devises many interference and avoids rule, such as CSMA/CA ((Carrier Sense Multiple Access/Collision Avoidance, i.e. csma/method for collision avoidance).As shown in Fig. 2, this side The basic principle of method is that either terminal is wanted before sending signaling or data by the AP (Access Point, access point) of WiFi Whether there are AP or terminal in transmission/reception signaling or data around first Monitor detection, if so, then continuing to monitor, Zhi Daojian It hears without until.If it is not, generating a random number as back off time, in this back off time, if do not examined Signaling or data transmission are measured, then after back off time terminates, AP or terminal can start to send signaling or data.

And due to there is good orthogonality to ensure that interference level in LTE network, so the uplink and downlink of base station and user pass It is defeated not have to consider whether surrounding has base station or user being transmitted.If LTE does not also consider when being used in unauthorized frequency range Whether surrounding has other equipment using unauthorized frequency range, then great interference will be brought to WiFi equipment.As long as because of LTE There is business to be just transmitted, without any monitoring rule, then WiFi equipment cannot just be transmitted when LTE has business transmission, only It can wait until that LTE business is transmitted, can just detect channel clear, can just be transmitted.

So LTE is when using unauthorized frequency range, one of most important key point is to ensure that LAA (licensed- Assisted access, LTE authorize the access technology of frequency spectrum auxiliary) it can be on the basis of fair friendly and existing access Technology (such as WiFi) coexists.And there is no the machine of LBT (Listen Before Talk, listem-before-talk) in traditional LTE system It makes to avoid collision.In order to preferably be coexisted with WiFi, LTE needs a kind of LBT mechanism.

Existing LBT mechanism is all frame based LBT (Listen Before Talk, listem-before-talk) frame structure, As shown in figure 3, the period of LBT is fixed, the time of CCA (Channel Clear Assessment, channel idle detection) It is most starting for each period.For example, in LTE frame structures, using 10ms as the period, CCA occupies 1 of the foremost of #0 subframes Or multiple symbol.Under the structure in this fixed period, only #0 work songs frame can just be CCA, if business is in #1 work songs Frame reaches, it is also necessary to after the #0 work song frames of next cycle carry out CCA, it could judge whether channel can occupy, from And bring prodigious delay.

And the existing LBT mechanism based on load (LBE), cardinal principle are to carry out channel inspection at once when loading arrival It surveys, if detection channel idle, horse back transmission data business;If detecting channel busy, a number N is randomly choosed, is being connect In the Channel Detection Time to get off, if detecting channel busy, N is constant, if detecting the channel spare time, N-1, and when N is kept to 0, It then can be with transmission data.

The LBT mechanism of either FBE or LBE, feature are all that the channel in unlicensed spectrum is sometimes idle Available mode is sometimes busy down state.And it is to be constantly in available mode to authorize the channel on frequency spectrum, then carrying Under wave polymerization, terminal authorize frequency spectrum and unlicensed spectrum using a kind of DRX (discontinuous reception, it is discontinuous Receive) configuration cannot reach best energy-saving effect.

Therefore a kind of new technical solution is needed, terminal can be enable to maximize energy saving, improve frequency spectrum service efficiency, and carry High throughput of system.

In the technical scheme, second discontinuous reception parameters of the terminal on the serving cell of different unlicensed spectrums Configuration can be different.

With reference to Fig. 6 to Figure 12 technical solutions that the present invention will be described in detail.

The present invention mainly proposes under carrier wave flowcollector aggregation scheme FlowCollector that terminal can use different in mandate frequency spectrum and unlicensed spectrum DRX (Discontinuous Reception, discontinuous reception) is configured, and different unauthorized carrier waves can also use not Same DRX configurations.

Specific method is as follows:

(1) base station configures same set of DRX ginsengs when to terminal configuration DRX configurations on multiple carrier waves on authorizing frequency spectrum Number.And it can be configured on the carrier wave in one or more unlicensed spectrums different from the DRX parameters of carrier wave on frequency spectrum are authorized One or more sets parameters.

(2) as shown in fig. 6, what is provided is in LTE, if using FBE (Frame Based Equipment, base is based on In frame structure trigger Channel Detection equipment) LBT (Listen Before Talk, listem-before-talk) mechanism when, frame structure Example.Wherein when the period is 10ms, a period includes CCA (Clear Channel Assessment, channel idle detection) (described CCA detection times and LBT detection times are a meanings in text) channel status detection time, Channel holding time (inspection When measuring channel idle) and the idle times.The Idle times to prevent surrounding primarily to have the desired access of other equipment unauthorized Frequency spectrum so the equipment after occupying channel for a period of time, needs after discharging the idle times, then carries out CCA detections.

As shown in fig. 7, what is provided is in LTE, if using based on LBE (Load Based Equipment, based on load Trigger Channel Detection equipment) LBT mechanism when, frame structure example.In the case of LBE, LBT mechanism does not have the fixed period. When business reaches, CCA Channel Detections are carried out for the first time, are detected channel idle, are then sent.When busy channel is accounted for maximum channel With the time, and when data have not been sent also, needs to use extended CCA, i.e. random value N, be detected in next CCA In, if detecting channel busy, N is constant;If detecting channel idle, N-1, when N is kept to 0, then transmission data.

(3) as follows for the DRX configuration guidelines in unlicensed spectrum:

1, when base station is in Channel Detection Time or idle period times, terminal should be in sleep state;

2, when base station detects channel busy, terminal keeps sleep state, need not wake up.

3, when base station detects channel idle, part or all of terminal is waken up.

According to the criterion provided in (three), and the background that is provided in (two), it can be seen that the LBT mechanism based on FBE Under, the DRX mechanism of terminal is easier to design.As shown in Figure 8:The period of DRX is the period of the LBT mechanism of FBE, what terminal was waken up Start time is after CCA Channel Detection Times terminate, channel idle indication signaling or be directly before dispatch is sent.That There are many situations for the awake time span of terminal:

1, one is base stations to detect that channel busy, terminal find that channel is in busy shape according to channel idle indication signaling State is then gone to sleep.In this case, the time that terminal is waken up is exactly the time for detecting channel idle indication signaling.As shown in Figure 8 The time waken up.

2, one is base stations to detect that channel idle, terminal find that channel is in idle shape according to channel idle indication signaling State is divided into and is operated for two kinds in this case:

1) as shown in figure 9, one is all terminals in the Channel holding time of base station, it is always maintained at wake state, because It is for Channel holding time nor very long, and load will not be too heavy in unlicensed spectrum, may dispatch any one at any time Terminal, so all terminals are all waken up, each subframe monitors PDCCH, judges whether oneself is scheduled.

2) as shown in Figure 10, another kind be terminal is also divided into multiple group in BTS channel holding time, such as The terminal of one of group will be scheduled in the first half of Channel holding time, so waking up in first half;Another The terminal of group will be scheduled in the latter half of Channel holding time, so waking up in latter half.Section further in this way The about energy consumption of terminal, but be restricted in terms of scheduling freedom.Such case can also be user at more than two Group, but the time union that the user of all group wakes up is greater than equal to Channel holding time.

(5) wherein, the case where (four) give FBE, the case where next providing LBE.Firstly, because being based on load LBT mechanism, then base station be difficult determined when load come, when carry out channel status detection.In this feelings Under condition, need that the auxiliary of frequency spectrum is authorized to be in dormant terminal in unlicensed spectrum to wake up.Specific process is as follows (the case where certainly, which is also applied for based on FBE):

1, when not having down load needs to be transmitted in the unlicensed spectrum, terminal is in the unlicensed spectrum sleeps Dormancy state.

2, when there is down load needs to be transmitted in the unlicensed spectrum, base station carries out channel shape in unlicensed spectrum State detects, if detecting channel idle, base station is on the mandate frequency spectrum that terminal is being monitored or other terminals are being supervised It is sent in the unlicensed spectrum listened and wakes up signaling, terminal is waken up in the unlicensed spectrum.

3, be based on above-mentioned 2nd point described in, when detecting channel idle at any time to meet base station, can wake up by (we term it unlicensed spectrums for these terminals as the terminal of auxiliary serving cell (Scell) for cell in the unlicensed spectrum Fn service terminals) this condition, need the DRX by all unlicensed spectrum Fn service terminals on authorizing frequency spectrum to meet centainly Criterion, as described below:

1) wake-up time in DRX cycle of these terminals on authorizing frequency spectrum should be uniformly distributed as far as possible, in this way When base station detects unlicensed spectrum Fn channel idles at any time, wake-up time will directly can be on authorizing frequency spectrum Terminal scheduling to unlicensed spectrum on, improve resource utilization.

2) different if there is in multiple unlicensed spectrums, the terminal in each unlicensed spectrum needs to meet above-mentioned criterion Unlicensed spectrum on terminal between can not have to comprehend above-mentioned criterion.

As shown in figure 11, such as on unlicensed spectrum F3, there is cell addition upper SCell of 15 terminals by F3, that 15 terminals are divided into following 5 UE group, the union of wake-up times of each UE group on authorizing frequency spectrum is necessary It is the entire period.In this way, when base station detects the down channel free time on unlicensed spectrum F3 near t1 the and t6 times, The terminal that UE group1 can be dispatched goes to transmit and receive data in unlicensed spectrum;When base station is detected near t2 the and t7 times When down channel free time on to unlicensed spectrum F3, the terminal that can dispatch UE group2 is gone to send in unlicensed spectrum and is connect Receive data ...

4, waking up signaling can be:

1) Carrier Indicator when cross-carrier dispatch cross carrier scheduling are multiplexed CIF value, is set to point to the value of the unlicensed spectrum by Field (CIF, carrier wave instructions field).

2) MAC activation signalings are multiplexed, the SCell in the unlicensed spectrum is activated.

3) multipling channel free time indication signaling.

4) new wake-up signaling is designed.Indication signaling is such as controlled using new media access control signaling or physical down.

5, the trigger condition from waking up sleep:

1) wake-up time reaches maximum channel holding time.

2) sleep state can be entered by receiving the instruction of base station signaling, such as when the data of the terminal have passed etc..

(6) it is main serving BS that the method for such case based on LBE, which can also be used in LTE, and WLAN is as auxiliary service base The case where when standing or being controlled by LTE by carrier wave polymerization or dual link as auxiliary serving cell.

Wherein, when Figure 12 shows the LBT mechanism of LBE, when the DRX of terminal in frequency spectrum auxiliary unlicensed spectrum being authorized to wake up Between flow chart.

As shown in figure 12, when the LBT mechanism of LBE, the serving cell of frequency spectrum is authorized to assist the serving cell of unlicensed spectrum On the detailed process of DRX wake-up times of terminal include:

Step 1202, when the load increases, judge whether to need to transmit on the serving cell of unlicensed spectrum, judge As a result it is when being, to enter step 1204.

Step 1204, it determines the unlicensed spectrum to be added to ancillary service and in the terminal group of wake state.

Step 1206, the terminal pocket transmission fast wake-up signaling is given.

Step 1208, to the terminal transmission data in the terminal group in unlicensed spectrum.

Technical scheme of the present invention is described in detail above in association with attached drawing, technical solution through the invention, by for eventually The serving cell of mandate frequency spectrum and the serving cell of unlicensed spectrum at end configure different discontinuous reception parameters, can make end End can maximize service efficiency that is energy saving, while improving frequency spectrum, and improve throughput of system.
