Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of data buffer storage state reporting and uplink scheduling method and equipment.
Background technology
In downlink data transmission process, scheduling sends and is all completed by base station (eNB) with data, the scheduler that is positioned at base station has understanding accurately for the data volume of the data buffer zone of each terminal (UE), therefore can carry out reasonably scheduling according to the state of terminal data buffering area and distribute with resource.
And at up direction, data buffer storage state reporting (Buffer Status Report, BSR) be usually used in data communication system and support up-bag dispatching judgement, as for adopting high speed uplink bag access (High Speed Uplink Packet Access, HSUPA technology) universal mobile telecommunications system land radio access web (UMTS Terrestrial Radio Access Network, UTRAN).Ascending grouping scheduling function is positioned at media access control (MAC) layer of base station, if base station dispatcher can not be known the data buffer storage state of terminal, has no idea to carry out rational resource distribution, thereby can greatly reduce resource utilization ratio.Therefore need UE to carry out data buffer storage state reporting.
The content of BSR is the buffer area data volume in the logic channel group (Logical Channel Group, LCG) of the MAC layer of UE, and by MAC signaling, BSR MAC control information unit (CE) completes.A LCG comprises multiple logic channel sequences, and the maximum number of the logic channel sequence that the LCG supporting in Long Term Evolution (LTE) system comprises is 4.
In specific implementation, in LCG, data cached data volume is by the buffer size in BSR MAC CE (Buffer Size) domain representation.Concrete, pre-defined 64 buffer size grades, the corresponding BSR index value of each buffer size grade, the corresponding buffer data weight range interval of each BSR index value, this buffer data weight range interval is made up of a buffer area data volume lower limit and a buffer area data volume higher limit; In the time that data cached data volume size is in some buffer data weight ranges interval, Buffer Size territory is just encapsulated as the interval corresponding BSR index value of this buffer data weight range; ENB end is to estimate the required data volume reporting of UE according to the BSR index value in the Buffer Size territory in BSR MAC CE.3GPP 36.321 agreements specify that the Buffer Size territory in BSR MAC CE takies 6bit.
The form of BSR MAC CE is divided into following several:
Short BSR and block BSR form: as shown in Figure 1A, comprise logic channel group mark (LCGID) territory and corresponding buffer size territory.ENB receives after this BSR MAC CE, the up logic channel group of correspondence of just knowing corresponding UE has how many business datums to send, because eNB is to a logic channel group Resources allocation, so just mean that these resources can be shared by the logic channel of this logic channel group, each logic channel can obtain the scheduling how many resources depend on UE, therefore UE must carry out Resources allocation according to service attribute, otherwise cannot ensure the service quality (QoS) of corresponding business;
Long BSR form: comprise four buffer size territories, corresponding LCG ID is respectively #0, #1, #2, #3, as shown in Figure 1B.
Base station side judges the required data volume reporting of UE by the BSR index value in Buffer Size territory, generally there are two kinds of modes: get the buffer area data volume higher limit in the buffer data weight range interval that this BSR index value is corresponding as the required data volume reporting of UE, or get the buffer area data volume lower limit in buffer data weight range interval that this BSR index value is corresponding and the mean value of buffer area data volume higher limit as the required data volume reporting of UE.Therefore, there are some deviations in the up data volume meeting to be sent of UE and actual conditions that base station dispatcher obtains, has affected the precision that resource is distributed.
Realizing in process of the present invention, inventor finds to exist in prior art following technical problem:
In BSR index value (index) table from 3GPP 36.321 agreements, can find out, the interval of the buffer area data volume bound that each BSR index value is corresponding is approximately 15% left and right of the mean value that BSR index value is corresponding.That is to say, enough distribute in resource under the prerequisite of use, carry out resource distribution according to the buffer area data volume higher limit in buffer data weight range interval corresponding to BSR index value, can cause approximately 15% the wasting of resources; Carry out resource distribution according to the buffer area data volume lower limit in buffer data weight range interval corresponding to BSR index value and the mean value of buffer area data volume higher limit, conference causes approximately 8% the wasting of resources.Because UE can not, by accurately reported data amount information of current BSR mechanism, therefore, may cause Physical Resource Block (PRB) utilance not high, the situation that Radio Resource is wasted.
