Description

Buffer status report reporting method and user device

A kind of Slow rushes the report method and user equipment of zone state report

Technical field is the present invention relates to wireless communication technology field, and Slow rushes the report method and user equipment of zone state report in more particularly to a kind of wireless network（User Equipment, abbreviation UE).

Background technology

The Evolved UTRAN of 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, abbreviation LTE) system（Evolved Universal Terrestrial Radio Access Network, abbreviation E-UTRAN) in, the data of up-link are transmitted by physical uplink link shared channels (Physical Uplink Shared Channel, abbreviation PUSCH).By evolved base station（Evolved NodeB, abbreviation eNB) uplink radio resources are distributed to each user equipment（User Equipment, abbreviation UE).The multiple access technique that E-UTRAN is used is OFDM access（Orthogonal Frequency Division Multiplexing Access, abbreviation OFDMA) technology.The wireless heterogeneous networks of LTE system（Radio Resource Control, abbreviation RRC) layer can send RRC information and rrc layer link, configuration systematic parameter and many processes of transmission UE ability parameters etc. are set up between UE and eNB to realize.Wherein, the RRC message of downlink is in physical down link sharing channel（Physical Downlink shared Channel, abbreviation PDSCH) on send.Some common parameters related to system, the information such as subdistrict frequency point and cell system bandwidth is then the UE transmissions into all cells in broadcast message from eNB, broadcast message is sent on Physical Broadcast Channel (Physical Broadcast Channel, abbreviation PBCH).In order to be able to each UE is according to the demand assignment resource of oneself and provides service, to realize preferable multiplexing performance in uplink, and also to which abundant flexible and efficient utilization system bandwidth, LTE system has formulated special control message for the uplink transmission resource distribution of user.Wherein, the control message for being exclusively used in carrying out PUSCH resource allocation is to be sent to UE by eNB, the resource allocation control message is also known as uplink grant (UpLink Grant, abbreviation UL Grant), UL Grant are sent on physical downlink control channel (Physical Downlink Control Channel, abbreviation PDCCH). In order to ensure to give each UE rational distributing radio resources, LTE system requires that UE reports the data volume state that oneself Slow rushes area's memory storage, and this report is rushed zone state with Slow and reported（Buffer Status Report, abbreviation BSR) form report eNB.In LTE system, wave point logic channel（Logical CHannel, abbreviation LCH) different priority are provided with, these LCH are divided into 4 logic channel groups（Logical Channel Group, abbreviation LCG), what BSR was reported is exactly the information of all LCH data to be transmitted amount in UE each LCG group sequence number and group.Because BSR is the important reference information that eNB carries out rational wireless resource scheduling to UE, therefore LTE system defines a variety of BSR type and transmission rule.According to the difference of triggering BSR event, BSR, which is divided into conventional Slow and rushes zone state report (Regular BSR), cycle Slow, rushes zone state report（Periodic BSR) and filling Slow rush zone state report（ Padding BSR ) .Wherein, Regular B SR trigger condition includes：

>The upper strata for having high priority logic channel, which can be transmitted data to, to be reached, and the priority for the existing LCH data that its priority ratio UE Slow are rushed in area is high；

>Serving cell changes；BSR retransmission timers（RETX-BSR-TIMER) time-out, and UE Slow are rushed in area the data that can be transmitted.

Periodic BSR trigger condition is：If BSR cycle timers（PERIODIC BSR TIMER) time-out, then trigger Periodic BSR.

Padding BSR trigger condition is：It is also to be sent without Periodic BSR if both to be sent without Regular BSR, and the amount of bits for being used to fill in allocated up-link PUSCH resources is more than or equal to BSR MAC control members（Control Element, abbreviation CE) and its MAC heading（Subheader size sum), then trigger Padding BSR.

Padding BSR are the BSR of filled-type, are Regular BSR and Periodic BSR supplement, relative, and Regular BSR and Periodic BSR can be included into the BSR of non-filling type.When up-link does not send Regular BSR and Periodic BSR, Padding BSR can allow eNB to obtain the situation that UE Slow rush area's LCG data variations more in time.

Regular BSR and Periodic BSR are encapsulated as medium access control layer protocol data cell A MAC CE in (Media Access Control Protocol Data Unit, abbreviation MAC PDU).Padding BSR are then the filling bits for being filled in MAC PDU（Padding in).MAC PDU are transmitted on PUSCH.According to the consensus standard of current LTE MAC layers（3GPP TS36.321) definition, foregoing MAC PDU are as shown in figure 1, a MAC PDU is by a MAC header（Header), 0 or multiple MAC CE, 0 or multiple MAC Service Data Units（Service Data Unit, abbreviation SDU) and optional filling bit（Padding) constitute.MAC header is made up of multiple MAC sub-headers, and each MAC sub-headers are corresponding in turn to the MAC CE arranged after MAC header, MAC SDU or Padding, as shown in Figures 2 and 3 according to the sequencing of arrangement.BSR MAC CE MAC sub-headers correspond to Fig. 3, are R/R/E/LCID forms, and wherein R is reserved bit, and E is extension bits, represents there are other sub- headings after the sub- heading.The LCID included in MAC sub-headers is corresponding MAC CE or MAC SDU or Padding type, and such as up LCID's is explained as follows.

, escaped so that A is counterSee, definition be defined in the current standards of LTE release 8, in order to adapt to the demand of the current and following various wireless traffics being skyrocketed through, LTE release 8 next evolution standard also has begun to enter formulation process, namely senior LTE (LTE- Advanced, abbreviation LTE- A) standard.

LTE-A is third generation partner program（The 3rd Generation Partner Project, referred to as 3 GPP) tissue is to meet International Telecommunication Union (International Telecommunication Union, abbreviation ITU) advanced international mobile communication（International Mobile Telecommunication- Advanced, abbreviation IMT-Advanced) requirement and the standard released.Lte-a system is an evolution version in the system-baseds of LTE release 8, it introduces many new technologies to meet IMT-Advanced primary demand, the important technology of one of which is exactly carrier aggregation (Carrier Aggregation, abbreviation CA).Due to the property in short supply of current radio spectrum resources, the frequency spectrum resource that each mobile operator in the world possesses is often more scattered, and IMT-Advanced requires that the index of peak rate is higher（Support to support lGbps under 100Mbps, Hypomobility under high mobility), IMT-Advanced requirements can not be met with current LTE standard maximum 20MHz bandwidth, so needing to extend to more high bandwidth, such as FDD（Frequency Division Duplex, abbreviation FDD) Maximum supports 80MHz, time division duplex（Time Division Duplex, abbreviation TDD) it is maximum support 100MHz, so the data volumes that can transmit of UE for LTE with respect to also increasing several times.In addition to bandwidth increase, in order to reach higher speed, Multiinputoutput (Multi Input Multi Output, abbreviation MIMO) is also the core technology for lifting lte-a system handling capacity.Consider upstream bandwidth increase（With respect to 5 times of LTE bandwidth）With up double-current MIMO (with respect to 2 times of LTE single currents）, in lte-a system, UE upstream rate most senior general rises to 10 times of LTE.

(Rel-10) the system CA of LTE-A versions 10 is descending and/or up respectively by most 5 component carriers（Component Carrier, abbreviation CC) it is aggregating to support maximum 100MHz transmission bandwidths respectively, it is up（UpLink, abbreviation UL) CC sum configuration be less than or equal to it is descending（Downlink, abbreviation DL) CC sum configuration.Each CC corresponds to a mixed automatic retransfer（Hybrid Automatic Repeat Request, abbreviation HARQ) entity and transmission channel.There is an independent PDCCH to indicate the resource allocation on this CC or the resource allocation on other CC respectively on each DL CC, be divided into downlink resource distribution（DL assignment) or uplink authorization (UL grant) situation.When being configured with CC indexes（CIF the CIF for having 3bit in the case of), on PDCCH indicates component carrier identification information.1 downlink main carrier to carry is respectively configured in UE（DL PCC, Downlink Primary CC) and 1 up main carrier（UL PCC, Uplink Primary CC), it can match somebody with somebody and set to 0 ~ 4 descending secondary carriers（DL SCC, Downlink Secondary CC) and/or 0 ~ 4 upstream auxiliary carriers（ UL SCC, Uplink Secondary CC ).DL PCC and UL PCC constitute UE main serving cell（), PCell PCell provides safety and Non-Access Stratum mobility information（Security and NAS mobility Info), synchronization, access, system information, the function such as paging, UE Stochastic accessings can only be carried out by PCell.UL PCC are configured with transmission HARQ ACK/NACK and (confirm/not confirmed）, dispatch request（Scheduling Request, abbreviation SR), channel quality indicate（Channel Quality Indicator, abbreviation CQI) etc. signaling PUCCH resources.UL SCC that DL SCC are associated with it composition time serving cell (SCell), SCell provides higher bandwidth and data throughout as the increased Radio Resource of institute, and SCell may also not include UL SCC and configure.UL PCC and DL PCC pass through the information association indicated by system information block 2 (SIB2)；Information associations of UL SCC and the DL SCC by SIB2 or dedicated signaling as indicated by RRC signaling；UL SCC can also be associated with DL SCC or DL PCC according to the reference DL CC or the reference DL CC of measurement timing advance that measure descending path loss.Whenever, the UE of RRC connections (RRC-CONNECTED) state must keep a DL PCC and a UL PCC configuration.The angle managed from UE power savings and CC, eNB can pass through MAC CE activation/deactivation DL SCC, DL PCC can not be activated/deactivate.UE is not listening to PDCCH on the DL SCC of deactivation status, PDSCH is not received, is adjusted without measurement related CQI, non-reception system information, the measurement for supporting mobility correlation, closing base band and/or radio frequency part module and the corresponding RF frequencies of progress.Whether need to support activation/deactivation function and corresponding UE behaviors for UL SCC for example whether stopping sending the reference signal on correspondence UL SCC（Sounding Reference signal, abbreviation SRS) or PUSCH data etc., current 3GPP is just under discussion.

The better embodiment of the present invention The present invention basic conception be：LTE-A CA support at least two Slow to rush area's data volume table of grading（That is BSR forms), (the first data volume table of grading, is represented the BSR forms that LTE system is used with BT0）With the BSR forms of the support high data rate used for LTE-A systems（Second data volume table of grading, is represented with BT1).UE selects BSR forms according to CC configuring conditions and/or radio condition, and its BSR is reported according to selected BSR forms.

UE can cause eNB is received can unambiguously recognize corresponding BSR forms after BSR by the explicit identification in BSR MAC CE or by preset rules.Scheme one：UE selects BSR forms according to UL CC configuring conditions.Specifically, Ke Yishi：When UE is configured with 1 UL CC, BT0 is selected;When UE is configured with the UL CC of more than 1, BT1 is selected.The program is based on the idea that be：When UE is only configured with a UL CC, it is impossible to reach more than upstream data rate higher under LTE Rel-8 single carrier cases and obtain bigger uplink authorization, therefore still it can calculate BSR using BT0.MIMO situation can also use BT0.When being configured with multiple UL CC, usually UE traffic needs or eNB dispatching requirements and need high data rate to support, bigger uplink authorization may be obtained, therefore can more accurately be dispatched using BT1.

Scheme two：UE selects BSR forms according to radio condition.Radio condition can refer to that descending path loss (DL pathloss) measurement result, or channel quality indicate (CQI) measurement result, or power headroom reporting (PHR) (PHR) value.(1) when radio condition is descending path loss measurement result：Instantly when walking along the street loss measurement result is higher than default descending path loss measurement result thresholding, UE selections BT0;Instantly when walking along the street loss measurement result is less than default descending path loss measurement result thresholding, UE selections BT0.Above-mentioned descending path loss measurement result can be it is following in one kind：The descending path loss measurement result of DL CC associated by the DL CC associated by any one UL CC that the minimum value or maximum or average value, UE of descending path loss measurement result are configured in the DL CC associated by all UL CC that DL PCC descending path loss measurement result, UE are configured descending path loss measurement result, specific UL CC.Incidence relation between UL CC and DL CC can be indicated based on SIB2 or RRC is indicated or descending path loss measurement ginseng Examine or measurement of timing advance reference.

When UE reports the BSR, the descending path loss measurement result can be reported simultaneously.

(2) when radio condition is that channel quality indicates (CQI) measurement result：When CQI measurement is less than default CQI measurement thresholding, UE selections BT0;When CQI measurement is higher than default CQI measurement thresholding, UE selections BT1.Above-mentioned CQI measurement can be it is following in one kind：The CQI measurement of DL CC associated by the DL CC associated by any one UL CC that the minimum value or maximum or average value, UE of CQI measurement are configured in the DL CC associated by all UL CC that DL PCC CQI measurement, UE are configured CQI measurement, specific UL CC.Incidence relation between UL CC and DL CC can be indicated based on SIB2 or RRC is indicated or descending path loss measurement reference or measurement of timing advance reference.

When UE reports the BSR, the CQI measurement can be reported simultaneously.

(3) radio condition is power headroom reporting (PHR)（PHR) during value：When PHR values are less than default PHR thresholdings, UE selections BT0;When PHR values are higher than default PHR thresholdings, UE selections BT1.Above-mentioned PHR values are one kind in following：It is all that UL PCC PHR values, UE are configured

The PHR values for any one UL CC that PHR minimum value or maximum or average value, UE is configured, specific UL CC PHR values, UE PHR values in UL CC.

, can upper 4 blunt PHR values simultaneously during the UE ^ blunt announcement BSR.The program is based on the idea that for when radio condition is bad, it is impossible to reaches more than upstream data rate higher under LTE Rel-8 single carrier cases and obtains bigger uplink authorization, therefore still can calculate BSR using BT0.MIMO situation can also use BT0.When radio condition is good, UE may obtain bigger uplink authorization, therefore can more accurately be dispatched using BT1.

Scheme one can be used in combination with scheme two, such as when UE is configured with multiple CC and radio condition is good, use BT1;Otherwise BT0 is used.Also other various possible combined situations are thought within the scope of the present invention.When triggering reports BSR, and when at least one UL CC has ascending resource, UE is according to selected BTO or BT1 calculate Slow and rush area's quantitative levels, generate BSR MAC CE, the BSR reported in the UL CC for having ascending resource.The present invention is expanded on further with specific embodiment below.Following examples are all with LTE BSR forms（Be named as BT0) on the basis of newly add a kind of BSR forms（It is named as BT1) exemplified by.Description is not repeated for adding the scene of more than one BSR forms, can be completed using 2 kinds of form similar modes.ENB and UE support CA and a variety of BSR forms.BT0 is LTE BSR forms；BT1 supports high data rate, can be with the fine-grained data represented between 150K to 1500K.Following table lists a kind of possible BT1, and wherein Slow rushes area's quantity（Buffer Size, abbreviation BS) the fine-grained Slow for denoting 150K to 1500K or so rushes area's data between class 4 8-62.The table is only used as a possible embodiment, and the present invention, which is not limited, must use the BSR forms.Given the correct time when on UE triggerings BSR, the BSR triggered here can be Regular BSR, Periodic BSR or Padding BSR, and BSR form selections are carried out according to the rule of respective protocol.
