Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of buffer status report report method and equipment.
Background technology
(LTE Advanced, LTE-A) peak rate of system is compared with Long Term Evolution (LTE) system huge raising to long-term evolution upgrading, requires to reach descending 1Gbps, up 500Mbps.Simultaneously, LTE-A system requirements and LTE system are compatible well, the maximum bandwidth 20MHz of LTE system.Based on improve peak rate, with the LTE system compatible with take full advantage of the needs of frequency resource, the LTE-A system has introduced carrier aggregation (Carrier Aggregation, CA) technology.
Carrier aggregation technology refer in a residential quarter up-downgoing respectively comprise a plurality of member carriers (ComponentCarrier, CC), rather than LTE and before wireless communication system in have only the pattern of a cover carrier wave.Base station (eNB) is to the unified management of the member carrier of the many covers in the residential quarter and scheduling.Member carrier can be continuous or discrete, for the LTE system compatible, the maximum bandwidth of each member carrier is 20MHz.
From terminal (UE) angle, UE is downlink data receiving and schedule information on a plurality of downlink member carriers simultaneously, sends upstream datas and to the feedback information of downlink data in a plurality of uplink member carrier.
The something in common of LTE-A system and LTE system is under the CA mechanism:
The first, the structure of packet data polymerized agreement (PDCP) layer, Radio Link control (RLC) layer is identical; The second, medium access control (MAC) layer function is identical, mainly UE is dispatched, and comprises priority and resource distribution etc.
In the LTE system, upstream priority is handled and data are multiplexing is finished by multiplexing polymerization (multiplexing andassembly) entity.
The difference of LTE-A system and LTE system is:
The first, there is one independently to mix automatic repeat requests (HARQ) entity at each member carrier; The second, the corresponding transmission channel independently of each member carrier; The 3rd, (Transport Block TB), cannot exchange member carrier during re-transmission to each member carrier independent body transmission block.
LTE and LTE-A system all are based on the system of scheduling, are the required running time-frequency resource of UE distribute data transmission by the base station, and terminal is carried out downlink data reception or upstream data transmission according to the dispatch of base station.
Transmitting uplink data is by base station scheduling, and base station dispatcher is determined can to permit (UL grant) notice terminal by uplink scheduling after the ascending resource distribution condition.The foundation that base station dispatcher carries out the ascending resource distribution is the upstream data amount that terminal will send, the i.e. buffer status of terminal.The base station wants to know the buffer status of terminal, just need terminal carry out to the base station reporting cached state (Buffer state report, BSR).The related mechanism of BSR is as follows:
Radio Resource control (RRC) layer parameter configuration that the first, BSR is relevant.
Rrc layer comprises following two timers at the parameter of BSR configuration in the LTE system:
RetxBSR-Timer: forbid the timer that BSR reports;
PeriodicBSR-Timer: periodically carry out the timer that BSR reports,
In the LTE system, have only a uplink member carrier, BSR be one at the process of UE, so the timer of rrc layer configuration is based on the UE configuration.
The second, BSR classification and trigger mechanism.
BSR is divided into conventional BSR (Regular BSR), periodically BSR (Periodic BSR) and three kinds of BSR (Padding BSR) incidentally, wherein:
Conventional BSR, trigger in following two kinds of situations: the first, the data that the priority of the data in the current buffering area of priority ratio (buffer) is higher arrive or script arrives for data are arranged among the empty buffer; Among the overtime and buffer of second, retxBSR-Timer data are arranged.
Periodically BSR triggers when periodicBSR-Timer is overtime.
Incidentally BSR if UE in organizing media access control protocol data cell (MAC PDU), also has surplus resources can use (padding), can trigger Padding BSR except the required resource of service data transmission.
The 3rd: BSR reports mechanism.
For Regular BSR and Periodic BSR, if (logicalchannel group LCG) has data to use to a unnecessary logic channel group, then reports long BSR (long BSR), otherwise reports short BSR (short BSR);
For padding BSR, if available bits (padding bit) number is more than or equal to (bit number of the bit number of shortBSR+MAC head (MAC subheader)), but less than (bit number of the bit number of long BSR+MAC subheader), if then UE has a unnecessary LCG to have data to use, then report the BSR (truncated BSR) of brachymemma, otherwise report short BSR; If padding bit number then reports long BSR more than or equal to (bit number of the bit number of long BSR+MAC subheader).
After triggering BSR, but Periodic BSR and Padding BSR will have the ascending resource time spent just can report, (the request base station is that UE distributes ascending resource for SchedulingRequest, SR) process but Regular BSR is not there being the ascending resource time spent then can trigger dispatch request.
The base station is after UE distributes ascending resource, if this resource has just enough sent all upstream datas, then can not send out BSR, only sends upstream data; If this resource sends all upstream datas inadequately, then preferentially report Regular BSR or Periodic BSR, the subsequent transmission scheduling is carried out according to the required upstream data amount of UE that reports BSR again in the base station.
A MAC PDU comprises a BSR at most.BSR priority is: Regular BSR=PeriodicBSR＞padding BSR, if a plurality of BSR trigger simultaneously, only report priority the highest, for Regular BSR and Periodic BSR owing to report content identical, all comprise whole available data amount informations among the UE buffer, report form identical, optional one reports and gets final product.The MAC layer is preferentially placed the MAC Control Element that comprises Regular BSR or Periodic BSR information when organizing MACPDU (Control Element CE), just places the service data unit (MACSDU) that comprises business datum thereafter.The priority of padding BSR is lower than business datum.
Processing after the 4th, BSR reports.
As long as BSR is triggered and can reports, then start or restart periodicBSR-Timer and retxBSR-Timer, but for the BSR of brachymemma, can not start or restart periodicBSR-Timer, can only start or restart retxBSR-Timer.
The 5th, BSR reports form.
BSR reports with the form of MAC CE, and the message format that reports comprises MAC head and MAC CE two parts, and the MAC CE of BSR comprises long BSR and two kinds of forms of short BSR again, and the BSR of brachymemma (truncated BSR) is identical with short BSR form.MAC form lacked the MAC CE of BSR or truncated BSR as shown in Figure 2 as shown in Figure 1 in the LTE system, and the MAC CE of long BSR as shown in figure 33.Wherein the implication in each territory is as follows:
LCID (Logical Channel ID) is Logic Channel Identifier, is used for the logical channel number of the corresponding load part of sign, and long BSR, short BSR, truncated BSR respectively have a LCID.
E is extended bit, and being used to indicate next byte (byte) is MAC head or MAC load.
R is reserved bit.
LCG ID is the logic channel group #, gives the correct time on the BSR in the LTE system to have divided 4 logic channel groups.
Buffer Size is the data buffer memory in the counterlogic channel group.
In realizing process of the present invention, the inventor finds to exist in the prior art following technical problem:
Also do not adopt at present the mechanism that reports of BSR in the system of CA technology, it is to need the problem that solves that the BSR that how to carry out UE in the CA system reports.

Embodiment
For UE in the system that solves employing CA technology can't report the problem of BSR, the embodiment of the invention provides the method for the reporting cached state in a kind of carrier aggregation system, in this method, terminal is after being self current data allocations uplink transmission resource waiting for transmission, if also exist surplus resources can with and satisfy and to trigger the incidentally condition of BSR, then report incidentally BSR to network side.
Referring to Fig. 4, the reporting cached state method in the carrier aggregation system that the embodiment of the invention provides specifically may further comprise the steps:
Step 40: terminal receives the uplink transmission resource information that network side distributes for the uplink member carrier of this terminal support, and this uplink member carrier can be one or more; The uplink transmission resource information that network side distributes for certain uplink member carrier can be carried in the UL grant message that sends at this uplink member carrier;
Step 41: terminal is determined the summation of available uplink transmission resource size on one or more uplink member carrier according to the uplink transmission resource information that receives, and is the current upstream data distribution uplink transmission resource waiting for transmission of terminal according to definite result;
Step 42: terminal is after uplink transmission resource is distributed end, determine whether remaining available uplink transmission resource can carry padding BSR, namely judge the data volume sum whether remaining available uplink transmission resource can the data carried by data amount comprises more than or equal to BSR MAC CE and MAC subheader, if, then definite remaining available uplink transmission resource can be carried padding BSR, otherwise, determine that remaining available uplink transmission resource can not carry padding BSR;
Step 43: when terminal can be carried padding BSR in definite remaining available uplink transmission resource, triggering reports padding BSR, and choose part or all of member carrier in one or more uplink member carrier, utilize the uplink member carrier of choosing to report padding BSR to network side.
As a kind of execution mode, before step 41, terminal can judge whether to satisfy the condition that reports conventional buffer status report (Regular BSR) or periodicity buffer status report (Periodic BSR) that triggers; And when judging that not satisfying triggering reports the condition of Regular BSR or Periodic BSR, summation according to available uplink transmission resource size on one or more uplink member carrier, be self current upstream data distribution uplink transmission resource waiting for transmission, and carry out subsequent step.Satisfy when reporting the condition of RegularBSR or Periodic BSR in terminal judges, terminal can be chosen a member carrier in one or more uplink member carrier, and utilizes the uplink member carrier of choosing to report Regular BSR or PeriodicBSR to network side.
In the present embodiment, a member carrier of choosing in one or more uplink member carrier is used for reporting incidentally BSR.
As another kind of execution mode, before step 41, terminal can judge whether to satisfy the condition that reports Regular BSR or Periodic BSR that triggers; If terminal judges satisfies the condition that reports Regular BSR or Periodic BSR that triggers, then terminal is being the current uplink business data waiting for transmission of terminal when distributing uplink transmission resource in the step 41, and also needing is that Regular BSR or Periodic BSR distribute uplink transmission resource.Accordingly, terminal is being chosen when reporting the uplink member carrier of padding BSR in the step 43, according to being that uplink business data and Regular BSR or Periodic BSR distribute after the uplink transmission resource the remaining available uplink transmission resource can the data carried by data amount, definite number that can carry the uplink member carrier of padding BSR, and from one or more uplink member carrier, choose this number member carrier, be used for reporting padding BSR; For example, network side is that 5 uplink member carrier have been distributed uplink transmission resource, terminal is being after uplink business data and Regular BSR or Periodic BSR distribute uplink transmission resource, remaining uplink transmission resource can the data carried by data amount be 20bit, the data volume that padding BSR comprises is 5bit, then from 5 uplink member carrier, choose 20/5=4 member carrier and be used for carrying padding BSR, should be noted that the member carrier that to have selected to carry regular/periodic BSR.
If terminal judges does not satisfy the condition that reports Regular BSR or Periodic BSR that triggers, then terminal is being chosen when reporting the uplink member carrier of padding BSR in the step 43, according to distribute after the uplink transmission resource the remaining available uplink transmission resource can the data carried by data amount for uplink business data, determine to carry the incidentally number of the uplink member carrier of BSR, and from one or more uplink member carrier, choose this number member carrier, be used for reporting padding BSR.For example, network side is that 5 uplink member carrier have been distributed uplink transmission resource, terminal is after distributing uplink transmission resource for uplink business data, remaining uplink transmission resource can the data carried by data amount be 25bit, the data volume that padding BSR comprises is 5bit, then chooses 25/5=5 member carrier and be used for carrying padding BSR from 5 uplink member carrier.
In the present embodiment, terminal is after judging that satisfying triggering reports the condition of regular BSR or periodic BSR, at first total resource is carried out the resource distribution according to the data volume of regular BSR or periodic BSR and the uplink business data amount of this UE, judge then whether surplus resources can carry BSR and BSRMAC CE, if can, then trigger padding BSR and determine the number of padding BSR according to surplus resources, be mapped to MAC PDU then, mapping MAC is the uplink member carrier that regular BSR or periodicBSR select carrying during PDU.Should be noted that when being mapped as MAC PDU the uplink member carrier of selecting carrying for padding BSR, the uplink member carrier of selecting for padding BSR is not included as the carrier wave that regular BSR or periodic BSR have taken.
In step 42, if determining remaining available uplink transmission resource, terminal can not carry incidentally BSR, if terminal has been judged the satisfied condition that reports Regular BSR or Periodic BSR that triggers before, then choose a member carrier in one or more uplink member carrier, and utilize the uplink member carrier of choosing to report Regular BSR or Periodic BSR to network side.
Among the present invention, from one or more uplink member carrier, choose when reporting the member carrier of BSR, it chooses mode: according to channel quality information and/or the Inter-Cell Interference Coordination ICIC information of each member carrier in one or more uplink member carrier, choose from one or more uplink member carrier be used to the member carrier that reports BSR; Perhaps, the picked at random member carrier is used for reporting BSR from one or more uplink member carrier.
When choosing according to the channel quality information of each uplink member carrier, can be from the uplink member carrier that can be used for reporting BSR the top-quality uplink member carrier of selective channel, for example can select the highest grade of MCS UL CC, UL CC carries in UL grant message;
When choosing according to the ICIC information of each uplink member carrier, can from the uplink member carrier that can be used for reporting BSR, select the minimum uplink member carrier of annoyance level, at this moment, need the base station in advance the ICIC information on each UL CC of UE to be sent to UE;
When choosing according to the channel quality information of each uplink member carrier and ICIC information, can be from can be used for reporting the uplink member carrier that selective channel is best in quality, annoyance level is minimum the uplink member carrier of BSR.
Below the present invention is specifically described:
Among the present invention, be that the one or more UL CC of the UE resource sum of distributing is as total resource with the base station, be the upstream data Resources allocation then, finish to also have afterwards remaining available resources and available resources to satisfy the overhead requirements of BSRMAC CE and MAC head if resource is distributed, then trigger reporting of padding BSR.
Can also report mechanism further to optimize to the BSR triggering based on this trigger mechanism, namely consider that according to the factors such as number of padding size, UL CC same UE can transmit one or more BSR at synchronization, the purpose of transmitting a plurality of BSR is exactly in order to reduce different UL CC channel circumstance differences to the influence of BSR propagation delay time.The present invention allows same UE can report one or more BSR at synchronization, and a plurality of BSR can be distributed on the UL CC, also can be distributed on a plurality of UL CC, is distributed in to be conducive to reduce channel quality on a plurality of UL CC to the influence of BSR propagation delay time.
One: one moment of scheme only reports a BSR.
The parameter that rrc layer need dispose comprises following two timer parameters:
RetxBSR-Timer: forbid the timer that BSR reports;
PeriodicBSR-Timer: periodically carry out the timer that BSR reports.
The BSR trigger mechanism is as follows:
Conventional BSR (Regular BSR), trigger in following two kinds of situations: the first, the data that the priority of the data in the current buffering area of priority ratio (buffer) is higher arrive or script arrives for data are arranged among the empty buffer; Among the overtime and buffer of second, retxBSR-Timer data are arranged.Above-mentioned two kinds of situations are the condition that reports Regular BSR that triggers;
Periodically BSR (Periodic BSR) triggers when periodicBSR-Timer is overtime, and namely periodicBSR-Timer is overtime for triggering the condition that reports Periodic BSR.
Incidentally (Padding BSR), each UL grant of the uplink transmission resource information of distributing for UL CC according to carrying of sending of base station dispatcher, the total amount of data that all resources of dispensed can be carried, for carrying out resource successively according to priority, distributes upstream data waiting for transmission then, if distributing, resource finishes to also have resource can use (padding) afterwards, and resource satisfies the demand of BSR MAC CE and MAC subheader expense, then triggers reporting Padding BSR.
BSR reports mechanism as follows:
For Regular BSR and Periodic BSR, if (logicalchannel group LCG) has data to use to a unnecessary logic channel group, then reports long BSR (long BSR), otherwise reports short BSR (short BSR);
For padding BSR, if available bits (padding bit) number is more than or equal to (bit number of the bit number of shortBSR+MAC head (MAC subheader)), but less than (bit number of the bit number of long BSR+MAC subheader), if then UE has a unnecessary LCG to have data to use, then report the BSR (truncated BSR) of brachymemma, otherwise report short BSR; If padding bit number then reports long BSR more than or equal to (bit number of the bit number of long BSR+MAC subheader).
After triggering BSR reports, Periodic BSR and Padding BSR will just can report when available uplink transmission resource is arranged, Regular BSR then can trigger SR (Scheduling Request when not having available uplink transmission resource, dispatch request) process, ascending resource is distributed to UE in the request base station;
The base station is after UE distributes uplink transmission resource, if this resource is only enough carried all uplink business datas, then can not send out BSR, directly sends uplink business data; If this resource is carried all uplink business datas inadequately, preferentially report Regular BSR or Periodic BSR, the BSR that the base station reports according to UE again determines to carry out the subsequent transmission scheduling after the required ascending resource amount.
An interior UE at most only reports a BSR clock cycle (TTI) in this programme.
BSR priority: Regular BSR=Periodic BSR＞padding BSR, if a plurality of BSR trigger simultaneously, only report priority the highest, because Regular BSR reports content identical with Periodic BSR, all comprise whole available data amount informations among the UE buffer, report form identical, optional one of them report and get final product.
BSR reports the carrier wave selection mode as follows:
Distributed uplink transmission resource if network side only is a uplink member carrier, then used this carrier wave to report BSR, otherwise needed to select to report the uplink member carrier of BSR, selection principle can adopt following three kinds:
First kind, can be used for reporting the channel quality of the uplink member carrier of BSR to select according to each, such as the top-quality uplink member carrier of selective channel from the uplink member carrier that can be used for reporting BSR, for example can select the highest grade of MCS UL CC among the UL grant;
First kind, can be used for reporting the disturbed condition of the uplink member carrier of BSR to select according to each, disturb minimum uplink member carrier such as from the uplink member carrier that can be used for reporting BSR, selecting, at this moment, need the base station in advance the ICIC information on each UL CC of UE to be sent to UE;
The third selects one at random from the uplink member carrier that can be used for reporting BSR.
Processing after BSR reports is as follows:
As long as BSR is triggered and can reports, then start/restart periodicBSR-Timer and retxBSR-Timer, but should be noted that the BSR for brachymemma, can not start/restart periodicBSR-Timer, only start or restart retxBSR-Timer.
The structure that BSR MAC CE adopts is shown in Fig. 1～3.
Two: one moment of scheme can report a plurality of BSR, regular/periodic BSR reports does not influence reporting of padding BSR, and a UE at most only reports a BSR in the TTI on a UL CC, but can report BSR at a plurality of UL CC simultaneously.
The parameter that rrc layer need dispose comprises following two timer parameters:
RetxBSR-Timer: forbid the timer that BSR reports;
PeriodicBSR-Timer: periodically carry out the timer that BSR reports.
The BSR trigger mechanism is as follows:
Conventional BSR (Regular BSR), trigger in following two kinds of situations: the first, the data that the priority of the data in the current buffering area of priority ratio (buffer) is higher arrive or script arrives for data are arranged among the empty buffer; Among the overtime and buffer of second, retxBSR-Timer data are arranged.
Periodically BSR (Periodic BSR) triggers when periodicBSR-Timer is overtime.
Incidentally (Padding BSR), each UL grant of the uplink transmission resource information of distributing for UL CC according to carrying of sending of base station dispatcher, the total amount of data that all resources of dispensed can be carried, for carrying out resource successively according to priority, distributes upstream data waiting for transmission then, if distributing, resource finishes to also have resource can use (padding) afterwards, and resource satisfies the demand of BSR MAC CE and MAC subheader expense, then triggers reporting Padding BSR.
BSR reports mechanism as follows:
For Regular BSR and Periodic BSR, if a unnecessary LCG has data to use, then report long BSR, otherwise report short BSR.
For padding BSR, suppose that network side is that N UL CC distributed resource, then:
When N=i:
If available bits (padding bit) number is more than or equal to (bit number of the bit number of short BSR+MAC head (MAC subheader)), but less than (bit number of bit number+MACsubheader of long BSR), if then UE has a unnecessary LCG to have data to use, then report the BSR (truncated BSR) of brachymemma, otherwise report short BSR; If padding bit number then reports long BSR more than or equal to (bit number of the bit number of longBSR+MAC subheader).
In N＞1 o'clock:
If padding bit is more than or equal to (bit number of the bit number of short BSR+MAC subheader) but less than 2* (bit number of the bit number of short BSR+MAC subheader), if then UE has a unnecessary LCG to have data to use, then report the BSR of a brachymemma, otherwise report a short BSR;
If padding bit is more than or equal to 2* (bit number of the bit number of short BSR+MAC subheader) but less than (bit number of the bit number of long BSR+MAC subheader), if then UE has a unnecessary LCG to have data to use, then can report the BSR of a plurality of brachymemmas, otherwise can report a plurality of short BSR, the triggering that the number of the BSR that specifically reports depends on padding bit size, distributed the number of the ULCC of resource, whether had regular BSR or periodic BSR to report;
If padding bit is more than or equal to (bit number of the bit number of long BSR+MAC subheader) but less than 2* (bit number of the bit number of long BSR+MAC subheader), then can report 1 long BSR, if padding bit is more than or equal to 2* (bit number of the bit number of long BSR+MAC subheader) then can report a plurality of long BSR, the triggering that the BSR number that specifically reports depends on padding bit size, distributed the number of the UL CC of resource, whether had regular BSR or periodic BSR to report.
After triggering reports BSR, but Periodic BSR and Padding BSR will have the ascending resource time spent just can report, but Regular BSR is not having the ascending resource time spent then can trigger the SR process, and ascending resource is distributed to UE in the request base station;
The base station is after UE distributes uplink transmission resource, if this resource is only enough carried all uplink business datas, then can not send out BSR, directly sends uplink business data; If this resource is carried all uplink business datas inadequately, preferentially report Regular BSR or Periodic BSR, the BSR that the base station reports according to UE again determines to carry out the subsequent transmission scheduling after the required ascending resource amount.
A UE can report a plurality of BSR in the TTI.
BSR priority: Regular BSR=Periodic BSR＞padding BSR.Regular BSR and Periodic BSR report does not influence padding BSR.Regular BSR and Periodic BSR be because it reports content identical, all comprises among the UE buffer all available data amount informations, reports form identical, and optional one reports and gets final product.If MAC layer this PDU when organizing MAC PDU comprises Regular BSR or Periodic BSR, then do not comprise padding BSR among this MAC PDU.
BSR reports the carrier wave selection mode as follows:
Distributed uplink transmission resource if network side only is a uplink member carrier, then used this carrier wave to report BSR, otherwise needed to select to report the uplink member carrier of BSR, selection principle can adopt following three kinds:
First kind, can be used for reporting the channel quality of the uplink member carrier of BSR to select according to each, such as the uplink member carrier of the top-quality required number of selective channel from the uplink member carrier that can be used for reporting BSR, for example can select the highest grade of MCS UL CC among the UL grant;
First kind, can be used for reporting the disturbed condition of the uplink member carrier of BSR to select according to each, such as the uplink member carrier of from the uplink member carrier that can be used for reporting BSR, selecting to disturb minimum required number, at this moment, need the base station in advance the ICIC information on each UL CC of UE to be sent to UE;
The third selects the uplink member carrier of required number at random from the uplink member carrier that can be used for reporting BSR.
Processing after BSR reports is as follows:
As long as BSR is triggered and can reports, then start/restart periodicBSR-Timer and retxBSR-Timer, but should be noted that the BSR for brachymemma, can not start/restart periodicB SR-Timer, only start or restart retxBSR-Timer.
The structure that BSR MAC CE adopts is shown in Fig. 1～3.
The present invention will be described with specific embodiment below:
Embodiment 1:
In the present embodiment, synchronization UE only reports a BSR, BSR trigger and the flow process that reports shown in Fig. 5 A:
Step 601:UE judges whether to satisfy the condition that reports Regular BSR/Periodic BSR; If then arrive step 608; Otherwise, to step 602;
Step 602: determine to be used for to report the number of the UL CC of BSR, and network side total resource of distributing can the data carried by data amount; Concrete, be the resource information that N_CC UL CC distributes if comprise network side in the UL grant message that UE receives, then determine to be N_CC for the number of the UL CC that reports BSR; It is that all resources of N_CC UL CC distribution can data carried by data amount sum that total resource that network side distributes can the data carried by data amount equals network side;
Step 603: distribute uplink transmission resource for the current business datum waiting for transmission of UE, divide timing to distribute successively according to the priority of each business datum;
Step 604: after resource is distributed end, judged whether remaining available resources, if then arrive step 605; Otherwise, process ends;
Step 605: judge whether to satisfy the trigger condition report padding BSR, namely judge the data volume sum whether remaining available resources can the data carried by data amount comprise more than or equal to BSR MAC CE and MAC subheader; If then arrive step 606; Otherwise, process ends;
