Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made should all belong to the scope of protection of the invention.

In dual link DC technologies, a UE can configure two small district's groups (Cell group, referred to as " CG "), or also be component carrier group (CC group)：One is main plot group (Master Cell group, referred to as " MCG "), and another is secondary cell group (Secondary Cell Group, referred to as " SCG ").

MCG refers to a small district's groups associated with MeNB, is made up of main plot (Primary Cell, PCell) and zero or more secondary cell (Secondary Cell, SCell).

SCG refers to a small district's groups associated with SeNB, is made up of main secondary cell (Primary Secondary Cell, PSCell) and zero or more secondary cell (Secondary Cell, SCell).

Wherein, PCell refers to that UE sets up wireless heterogeneous networks (Radio Resource Control, referred to as " the RRC ") cell of connection, the main plot provides safety-related parameter and is configured with physical uplink control channel (Physical Uplink Control Channel, abbreviation PUCCH) resource.PSCell refers to the secondary cell that PUCCH resource is configured with secondary cell group.In addition to PCell and PSCell, the SCell in MCG and SCG does not configure PUCCH resource.PUCCH channels are mainly used in transmission hybrid automatic repeat-request confirmation (HARQ-ACK), channel condition information (Channel State Information,) and the information such as dispatch request (Scheduling Request, SR) CSI.

For a user equipment (UE), it may be simultaneously present multiple business, or multiple DRB need to be transmitted, then in medium education (Medium Access Control, referred to as " MAC ") layer UE needs the ascending resource distributed according to base station, (sometimes referred to as up to authorize UL grants) Transmitted after multiple DRB data are multiplexed.In LTE, each DRB corresponds to a logic channel and configures a priority of logical channels.In LTE, the process that multiple DRB data are carried out into multiplexing transmission is referred to as priority of logical channels (Logical Channel Prioritization, referred to as " LCP ") process.

Specifically, among existing LCP processes are performed, rrc layer is controlled by controlling following parameter to MAC scheduling, these parameters are priority of logical channels, priority bit rate (Prioritized Bit Rate, abbreviation PBR) and duration parameter (Bucket Size Duration, abbreviation BSD).To each logic channel, UE should safeguard a state variable Bj.When related logic channel is set up, Bj should be initialized to 0, and then each Transmission Time Interval (Transmission Time Interval, abbreviation TTI) increase PBR, i.e., accumulated based on PBR*TTI, that is, each TTI adds a PBR.

PBR is counterlogic channel j PBR.But, Bj value can not always exceed the size of token bucket, and the size of a token bucket is PBR*BSD.And if when Bj value is more than logic channel j token bucket, then the value that should put Bj is PBR*BSD.Wherein, PBR can be configured to infinity, when the PBR of infinity is set in some logic channel, then can ensure this business in the case where resource is nervous, and other business will not being serviced.

Further, the embodiment of the present invention is carried for division, because division carrying sometimes can carry out transmitting uplink data only by an eNB, and sometimes, when the DRB data volume than it is larger when, it is necessary to pass through the transmission that two eNB carry out upstream data simultaneously.When division carrying carries out data transmission only by an eNB, LCP processes of the prior art can be reused completely, and the DRB needs the transmission rate PBR ensured also to be ensured by an eNB.And the division is carried when carrying out uplink by two eNB simultaneously, then division carrying is needed respectively in the independent logic channel of two eNB configurations, and a logic channel is directed to MeNB, and a logic channel is directed to SeNB.The PBR of division carrying is then ensured by two eNB joints, that is, existing LCP processes cannot be reused simply.

Alternatively, in embodiments of the present invention, as shown in figure 3, this method 100 also includes：

S130, when the data volume for the upstream data that the division is carried is more than or equal to the second predetermined threshold value, the first buffer status report is sent to the first base station, and send the second buffer status report to second base station, wherein, first buffer status report and second buffer status report include the total amount of data for the upstream data that the division is carried, or first buffer status report includes the first data volume in the upstream data that the division is carried to first base station transmission, and second buffer status report includes the second data volume in the upstream data that the division is carried to second base station transmission；

S140, when the data volume for the upstream data that the division is carried is less than second predetermined threshold value, the first buffer status report is sent to the first base station, or the second buffer status report is sent to second base station, first buffer status report and second buffer status report include the total amount of data.

In embodiments of the present invention, in buffer status report (the Buffer Status Report for the upstream data that division carrying is sent without triggering UE, abbreviation BSR) before, UE can pass through the S110 in the above method 100 and S120, it is determined that performing the first LCP process corresponding with first base station, and/or the twoth LCP process corresponding with the second base station is performed, also determine to send the upstream data of division carrying to first base station and/or the second base station.Alternatively, when the UE upstream datas for having new division carrying need to send, UE can be triggered and send BSR to base station, in order to base station collocating uplink resource；Or UE can postpone to send the upstream data that the new division is carried, and the upstream data that the division is carried is sent until triggering after the BSR for the upstream data that UE have sent the division carrying new on this, then to base station.When triggering UE transmission BSR, then according to the second predetermined threshold value, UE determines to send the BSR to first base station and/or the second base station.

In embodiments of the present invention, in order to which assisted network side is UE dispatching uplink resources, UE is needed to send BSR to eNB, and eNB is received after BSR, the upstream data amount that UE really needs to send can be approximately obtained, make it that the BSR that eNB is reported according to UE determines scheduling how many uplink transmission resource.Can Selection of land, for each logic channel, eNB can be assigned it in a logic channel group (Logical Channel Group, referred to as " LCG "), introduce LCG purpose, primarily to reduction signaling consumption.Because reporting a BSR if each logic channel, substantial amounts of signaling consumption can be brought.

In embodiments of the present invention, BSR is reported by the BSR MAC controlled entities (MAC Control Element) of MAC layer, and BSR can include two kinds of forms of short BSR (Short BSR) and long BSR (Long BSR).Wherein, as shown in figure 4, short BSR points are short BSR and the BSR (Truncated BSR) blocked, Short BSR or Truncated BSR forms can only report LCG BSR.Its form is made up of a LCG ID domain and corresponding buffer size (Buffer Size) domain；As shown in figure 5, Long BSR forms contain 4 Buffer Size domains, LCG ID 0~3 are corresponded to respectively.All LCG Buffer Size can be reported eNodeB together by the form.

Specifically, LCG ID domains length is generally 2bit, for the corresponding LCG of BSR for indicating to report, its value and IE:Logical Channel Config (logic channel configuration) Logical Channel Group (logic channel group) field correspondence.The a length of 6bit in Buffer Size domains, after indicating that all MAC PDUs of the UE in the TTI for sending this BSR are generated, wireless spread-spectrum technology (the Radio Link Control of correspondence LCG all logic channels, the summation of the remaining valid data that can be used for transmission referred to as " RLC ") in layer and PDCP layers, the data volume can be in units of byte, but PDU portion and MAC header information is not counted.

In embodiments of the present invention, RRC typically controls reporting for BSR by configuring two timers, i.e. periodicity BSR timers (periodic BSR-Timer) and BSR retransmission timers (retxBSR-Timer).Specifically, triggering UE transmissions BSR condition can include following several.The first is, when BSR is sky and has new data arrival, can to trigger UE and send BSR.Specifically, when all not dividing the upstream data of carrying on all LCG all logic channels, if now any one LCG any one logical message has the upstream data of division carrying, UE can be triggered and send BSR.For example, UE sends BSR for the first time.The BSR is properly termed as " Regular BSR ".

Alternatively, as one embodiment, second of trigger condition can be that the data of high priority logic channel are reached.Specifically, when there is data arrival in the logic channel of high priority, and the priority of the high priority logic channel, than currently have the priority of any one logic channel that data can transmit will be high when, UE can also be triggered and send BSR, the BSR is referred to as " Regular BSR ".

Alternatively, as one embodiment, the third trigger condition can according to retransmission time out timer, triggering UE send BSR.Specifically, BSR robustness is improved exemplified by, re-transmission BSR mechanism is provided in LTE, after have sent BSR in order to avoid UE, is not received within a certain period of time The ascending resource distributed to base station, when retransmission timer is overtime, can also trigger UE and send BSR.

Alternatively, as one embodiment, the 4th kind of trigger condition can be periodically transmission BSR.Specifically, according to cycle timer, UE updates BSR according to certain cycle to base station, for example, data reach the time that UE, UE send BSR, it is nonsynchronous that the time of uplink transmission resource (UL grant) is received with UE, while namely UE sends BSR and receives UL grant, data are ceaselessly also being filled into BSR, therefore, UE needs to be updated periodically the upstream data amount of division carrying, is also accomplished by periodically reporting BSR.The BSR is properly termed as " Periodic BSR ".

Alternatively, as one embodiment, the 5th kind of trigger condition can be filling triggering.Specifically, when there is ascending resource on UE, and when needing the upstream data sent to be not enough to fill up the ascending resource, if unnecessary bit bit can accommodate BSR, then these bit can be used to send BSR, the BSR is referred to as " Padding BSR ".

In embodiments of the present invention, above-mentioned five kinds of triggerings UE sends BSR condition, can set one or more of which, when being provided with a variety of conditions, could be arranged to meet one of them and can trigger, it can also be provided that meet it is multiple can just trigger, the present invention is not limited thereto.
