Description
Technical field
The present embodiments relate to the communications fields, and more particularly, to a kind of method of data transmission, user equipment
And base station.
Background technique
Multiple logic channels of one user equipment (User Equipment, UE) are included into different logic channel groups
The priority of (Logical Channel Group, LCG), base station each logic channel group when dispatching are different.UE reports caching shape
When state reports (Butter Status Report, BSR), the outgoing data amount of each logic channel group is counted, is separately reported, supplied
Do accurate scheduling decision in base station.If UE does not trigger BSR, but after discharging data packet, there are also some vacant wireless
Resource, and data can not be put, UE can send truncated BSR Padding BSR at this time.If UE has multiple logics to believe at this time
Road group has outgoing data, then UE sends truncated BSR to base station, wherein comprising highest priority and having that of outgoing data to patrol
Collect the outgoing data amount of channel group;If only one logic channel group of UE has outgoing data at this time, UE is sent to base station
Padding BSR, the outgoing data amount only comprising this logic channel group for having data.
UE sends BSR itself to base station and is also required to ascending resource, and base station is distributed ascending resource to UE at the time of needing, made
It smoothly reports BSR.For this purpose, long term evolution (Long Term Evolution, LTE) system introduces scheduling request
(Scheduling Request, SR) mechanism configures some SR resources for UE.These SR resources periodically occur, itself
Very little.UE tells the base station side UE to have data to need to send by SR resource, to send as how many specific data, it is also necessary to
BSR is indicated in detail.
The condition of some triggering BSR is defined in existing agreement, as long as meeting these conditions, UE triggers side BSR, triggering
When, UE does not generate specific BSR, and until there is ascending resource, UE just counts the outgoing data amount of sending instant, BSR is generated,
Issue base station.
The increase of development with mobile communication technology and the number using mobile data services, existing macrocellular are born
It carries and increasingly weighs, in order to provide the user with better service, third generation partner program (the 3rd Generation
Partner Project, 3GPP) introduce carrier wave polymerization (Carrier Aggregation, CA) technology.
In CA technology, multiple base stations can be used to provide service for the same UE, for example, by using micro-base station (Small
Cell it) cooperates with macro base station (macro eNB) and provides service for UE.Here micro-base station is referred to as cell, such as can
To be Home eNodeB (home eNB, HeNB), micro-base station (pico eNB), relay station (relay), remote radio (radio
Remote head, referred to as: RRH) etc. transfer points, coverage area and transmission power are smaller, the wide coverage of macro base station
And transmission power is larger.Functionally, macro base station can provide wide covering, be responsible for control signaling, and cell can then provide
User data enhancing, is responsible for all or part of user service data.This mode can also be referred to as across station shunt mode.
It may result in base station hair due to there is multiple websites to provide uplink scheduling for UE across the UE under the shunt mode of station
Uplink scheduling resource is sent, but UE has but needed the case where sending without upstream data, causes the waste of scheduling resource.

204a, UE can send the first BSR to first base station, so that first base station carries out uplink scheduling.
It should be noted that the present invention is not restricted to the execution sequence of step 203a and step 204a, for example, step
203a can also be carried out simultaneously before step 204a after step 204a, or with step 204a.
The uplink scheduling information of 205a, UE reception first base station.
206a, UE send the first upstream data to first base station according to uplink scheduling information, which includes that UE works as
The preceding moment it is data cached.
Optionally, between step 204a corresponding first moment and step 206a corresponding second moment, if UE was once
Through transmitting upstream data to the second base station, then UE, can be in the first upstream data when sending the first upstream data to first base station
The 2nd BSR of middle carrying.2nd BSR is BSR of the UE before the second moment sent data.After first base station receives the 2nd BSR,
Uplink scheduling information can be sent to UE according to the 2nd BSR, provide uplink scheduling for UE.
207a, UE compare all first business of the data cached data volume and UE of current all first business of UE
Data cached corresponding second buffer data size threshold value.
Wherein, the second buffer data size threshold value can be the first buffer data size threshold value, is also possible to one and is greater than
The value of first buffer data size threshold value.Similar with the first buffer data size threshold value, the second buffer data size threshold value is by controlling
Base station configuration processed.Under default situations, if control base station does not configure the second buffer data size threshold value, it may be considered that using
First buffer data size threshold value work judge, in other words, if control base station does not configure the second buffer data size threshold value,
Then the second buffer data size threshold value is equal to the first buffer data size threshold value.
If the data cached data volume of all first business of UE is data cached less than all first business of UE
Corresponding second buffer data size threshold value, thens follow the steps 205a.Meanwhile UE can choose to the second base station and send message,
Also it can choose and do not send message to the second base station.If UE selects to send message to the second base station, UE can be to the second base station
Sending indicates the data cached padding BSR for being 0, or defines a new MACCE, indicates remaining data by first base station
Transmission.
If the data cached data volume of all first business of UE is data cached greater than all first business of UE
Corresponding second buffer data size threshold value, thens follow the steps 208a.
The data cached of the UE of corresponding second buffer data size threshold value is equal to for buffer data size, it is a kind of optional
Scheme can be considered processing the case where greater than corresponding second buffer data size threshold value;Another optional scheme, can be considered small
It is handled in the case where corresponding second buffer data size threshold value.
Further, in step 207a, a timer can be added, for monitoring the slow of current all first business of UE
The data volume of deposit data is greater than the duration of the second buffer data size threshold value.If current all data cached of UE
Data volume is greater than being sustained for longer than or equal to scheduled time value, thening follow the steps for the second buffer data size threshold value
208a, it is no to then follow the steps 205a.If executing step 205a, UE can choose to the second base station and send message, can also be with
Selection does not send message to the second base station.The scheduled time value can be base station according to carrier policy or network environment shape
The time value that the factors such as condition determine, it is specific to determine the method present invention herein and with no restriction.When timer monitor continues
Between when, for buffer data size be equal to corresponding second buffer data size threshold value UE a kind of data cached, optional side
Case can be considered processing the case where greater than corresponding second buffer data size threshold value;Another optional scheme, can be considered and be less than
The case where corresponding second buffer data size threshold value, is handled.By increasing the monitoring of time value, can avoid because of data burst thing
The influence that moment flow wave zone caused by part comes.
Step 207a can be executed periodically, or triggered and executed according to certain event.
208a restores BSR trigger mechanism and/or the second base station to the data distribution transmission mechanism of UE.
Optionally, UE can send scheduling request information to the second base station, provide uplink scheduling to trigger the second base station for UE.
For example, UE, which sends a SR to the second base station, requests the scheduling of the second base station, and current BSR is carried in subsequent ascending resource
To the second base station.
Alternatively, optionally, UE sends instruction information to first base station, so that first base station notifies the according to the instruction information
The uplink scheduling of two base stations participation UE.Wherein, instruction information instruction the data cached of UE is greater than the second buffer data size thresholding
Value.For example, UE is notified the BSR of UE to second by the interface of first base station and the second base station by communicating first base station
Base station.
Alternatively, optionally, UE sends the information that scheduling is assisted in the second base station of request to first base station, in order to first base station
The second base station is notified to participate in the uplink scheduling of UE.
It is of course possible to which the present invention is herein with no restrictions there are also other modes for waking up the second base station.
It should be noted that restoring BSR trigger mechanism, there are many meanings, the first refers to restoring UE for pause data
Second base station of transmission reports the trigger mechanism and its report mechanism of BSR, refers to restoring UE in configuration shunting business second
When the BSR trigger mechanism and its report mechanism for first base station and the second base station, the trigger mechanism of BSR and its report
Mechanism may be diversified, such as UE, only to control base station transmission BSR report, UE is respectively to first base station and the second base station
The BSR of same content is sent, UE sends corresponding BSR of different data etc. to first base station and the second base station respectively, and the present invention exists
This is with no restrictions.
Optionally, in the embodiment of the present invention, UE can be directed toward control base station and send BSR information.Control base station receives BSR
After information, may be selected for BSR information to be transmitted to it is other provide the base station of point streaming service for UE, or provided to other for UE
The base station of streaming service is divided to send the instruction information that control base station is generated according to BSR information.Fig. 2 b is number of the embodiment of the present invention
According to the interaction diagrams of transmission.One embodiment of the present of invention is as shown in Figure 2 b, comprising:
The shunting service that 201b, UE receive first base station and the second base station provides.
In the embodiment of the present invention, first base station and the second base station provide data distribution service for UE, receive the upper line number of UE
According to.Particularly, first base station is the data cached base station being used for transmission lower than the first buffer data size threshold value, or
It says, first base station is used to be less than the data cached corresponding first buffer data size thresholding of UE when the data cached data volume of UE
Uplink scheduling is provided when value for UE.
Optionally, first base station is responsible for the ambulant base station of management UE, and in other words, first base station is control base
It stands.First base station can be macro base station at this time, and the second base station can be the adjacent macro base station or first base station of first base station
Micro-base station (cell).
Alternatively, optionally, the second base station is responsible for the ambulant base station of management UE, i.e. the second base station is control base station.
At this point, the second base station can be macro base station, first base station can be the adjacent macro base station or first base station of the second base station
Micro-base station (cell).
No matter first base station is control base station or the second base station is control base station, UE receives control base station as UE configuration
The first buffer data size threshold value.
In the embodiment of the present invention, the first buffer data size threshold value be in UE each the first LCG it is data cached
The threshold value of amount.Optionally, the first LCG refers to the LCG including shunting business, i.e., the first buffer data size threshold value is just in UE
LCG comprising shunting business, not for the LCG not comprising shunting business.Alternatively, optionally, the first LCG may include comprising shunting
The LCG of business and LCG not comprising the business of shunting, i.e. the first buffer data size threshold value is for all LCG in UE.Control base
It stands when configuring the first buffer data size threshold value for the first LCG of UE, a correspondence can be separately configured for each the first LCG
The first buffer data size threshold value, or be all first LCG configure a first unified buffer data size threshold value.It changes
Sentence is talked about, and the data cached corresponding first buffer data size threshold value of all first LCG in UE can be identical, can also not
Together.
The first targeted LCG's of first buffer data size threshold value is data cached, regardless of data cached in the first LCG
It is the data cached of the data cached or non-shunting business of shunting business, all entire LCG is comprehensively considered, entire LCG
Data cached corresponding the first buffer data size threshold value as a whole make comparisons.First buffer data size thresholding
The first corresponding LCG's of value is data cached, it may include SRB data also may not include SRB data.The of each the first LCG
One buffer data size threshold value may be the same or different.For example, it is assumed that it is respectively a, b and c that UE, which there are 3 LCG, correspond to
The buffer data size threshold value of LCG be respectively a1, b1 and c1.Then buffer data size threshold value a1, b1 and c1 can be equal,
It can not wait.
Optionally, as be used for transmission data volume lower than the first buffer data size threshold value UE data cached base
It stands, first base station is predetermined the base station of the base station that base station control base station determines or UE selection.In advance
Determining base station can be and be previously determined to be macro base station, or is previously determined to be micro-base station.The base station that control base station determines, can
To be the control base station base station specified when configuration shunts transmission, or it is determining according to factors such as channel conditions, network loads
Base station.The base station of UE selection, can be the base station that UE shares according to CQI, QoS and meet the selections such as situation.
202b, UE compare the data cached data volume of the first LCG of each in UE and the first LCG corresponding first one by one
Buffer data size threshold value.
It is data cached corresponding first data cached to compare the data cached data volume of the first LCG and the first LCG by UE
When measuring threshold value, need to compare corresponding first data cached of data cached data volume of each the first LCG of UE
Measure the relationship of threshold value.It is equal to the first LCG of corresponding first buffer data size threshold value for buffer data size, it is a kind of optional
Scheme, can be considered greater than corresponding first buffer data size threshold value the first LCG processing;Another optional scheme, can
The first LCG being considered as less than corresponding first buffer data size threshold value is handled, following to be related to sentencing for buffer data size threshold value
It is disconnected, it is similar.At this point, UE comparison result can be divided into three kinds of situations: the first situation, the first LCG's of each of UE
Data cached data volume is both less than its corresponding first buffer data size threshold value.Second situation, each of UE
The data cached data volume of one LCG is both greater than its corresponding first buffer data size threshold value.The third situation, the portion in UE
The data cached data volume of LCG is divided to be less than its corresponding first buffer data size threshold value.For the first case and third
Kind situation, executes step 203b;It for second situation, is executed referring to original shunt method, details are not described herein by the present invention.
203b sends low buffer data size to the second base station and indicates information.Wherein, which refers to
Show the data cached data volume of at least one LCG of UE lower than the first buffer data size door corresponding at least one LCG
Limit value.
If belonging to the first situation, all LCG's of the low buffer data size instruction information instruction UE is data cached

If belonging to the third situation, the part LCG's of the low buffer data size instruction information instruction UE is data cached
Data volume is lower than the first buffer data size threshold value corresponding to LCG, at this point, since there are also part LCG needs to be transferred in UE
Second base station, therefore the second base station also needs to provide uplink scheduling for UE.After UE receives the uplink scheduling information of the second base station,
Upstream data can be transmitted to the second base station according to the priority of UE itself, the method for transmission is similar with original method, and the present invention exists
This is repeated no more.
In the embodiment of the present invention, the low buffer data size instruction information is without explicitly pointing out part or all LCG
Data cached data volume is lower than the first corresponding buffer data size threshold value, and the second base station is it is only necessary to know that some or all
The data cached data volume of LCG is lower than the first corresponding buffer data size threshold value.
Optionally, if the buffer data size of each LCG of UE is both less than the first buffer data size door of corresponding LCG
Limit value (the first situation), then the low buffer data size instruction information can be only comprising data cached state lower than the first caching number
According to the instruction of amount threshold value.Alternatively, optionally, if there was only the of the buffer data size of part LCG less than corresponding LCG in UE
One buffer data size threshold value (the third situation), which includes buffer data size less than corresponding
The information of the LCG of the first buffer data size threshold value of LCG.For example, it is assumed that it is respectively a, b and c that UE, which has 3 LCG, it is corresponding
The buffer data size threshold value of LCG is respectively a1, b1 and c1, then if the buffer data size of a, b and c to be respectively smaller than its corresponding
First buffer data size threshold value a1, b1 and c1 of LCG, then the low buffer data size instruction information can be only comprising data cached
State is lower than the instruction of the first buffer data size threshold value;If it is corresponding that the buffer data size of only a and b is respectively smaller than its
The first buffer data size threshold value a1 and b1 of LCG, then low buffer data size instruction information includes that buffer data size is less than pair
The information of a and b of the first buffer data size threshold value of the LCG answered.
UE sends UE in the mode and step 203a of low buffer data size instruction information and sends low buffer data size instruction letter
The mode of breath is similar, and details are not described herein by the present invention.
In the embodiment of the present invention, low buffer data size instruction information can also be there are many manifestation mode.For example, sending caching
The BSR that data are 0, the BSR indicate to be somebody's turn to do in UE lower than the buffer data size of the LCG of corresponding first buffer data size threshold value
BSR may include the information of multiple LCG.Or new MACCE is defined, specify new RNTI to identify slow lower than corresponding first in UE

The value of first buffer data size threshold value.Similar with the first buffer data size threshold value, the second buffer data size threshold value is by controlling
Base station configuration processed.Under default situations, if control base station does not configure the second buffer data size threshold value, it may be considered that using
First buffer data size threshold value work judges that in other words, the second buffer data size threshold value is equal to the first buffer data size door
Limit value.It is similar with the first buffer data size threshold value, the data cached corresponding second buffer data size door of each the first LCG
Limit value may be the same or different.
The first LCG for buffer data size equal to corresponding second buffer data size threshold value, a kind of optional scheme,
It can be considered that the first LCG greater than corresponding second buffer data size threshold value is handled;Another optional scheme, can be considered and be less than
First LCG of corresponding second buffer data size threshold value is handled.
If each UE current the first LCG data cached data volume is both less than corresponding second caching of the first LCG
Data amount threshold values then follow the steps 205b.Similar with step 207a, UE can choose to the second base station and send message, can also
To select not send message to the second base station.If UE selects to send message to the second base station, UE can be sent to the second base station
It indicates the data cached padding BSR for being 0, or defines a new MACCE, instruction remaining data is passed by first base station
It is defeated.
If it is corresponding second data cached to be greater than the first LCG for the buffer data size of the first LCG some or all of in UE
Threshold value is measured, then executes 208b.
Further, in step 207b, a timer can be added, it is data cached for monitoring the first current LCG of UE
Data volume be both greater than the first LCG data cached corresponding second buffer data size threshold value duration.If in UE
