Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of half-persistence scheduling resources distribution method and base station.
Background technology
In a communications system, LTE (Long Term Evolution, Long Term Evolution) uses shared resource allocation scheduling
System, the scheduling method that current LTE determines is divided into two kinds：Semi-continuous scheduling (Semi-Persistent Scheduling, referred to as
) and dynamic dispatching SPS.
In LTE system, the voice service of whole circuit domains is eliminated, using VOIP (the Voice over of data field
Internet Protocol, the networking telephone) business.In VOIP business, speech coder according to fixed cycle output grouping,
As shown in figure 1, Fig. 1 shows VOIP business data transmission schematic diagrames.In transient state (without the call) stages, do not have
Voice packet needs scheduling, can now carry out the dynamic dispatching of other business；In talk spurt state (call) stages, user
Converse, it will usually a packet is produced per 20ms, in Silent period (call interval) stages, theory only has
160ms background phonemic notations once, do not have speech data to dispatch.VOIP packets are classified according to type of coding, and the most frequently used is：
WB-AMR (Wide Band adaptive Multi-Rate, AMR-WB coding) broadband high definition business, coding effect
Rate is 23.85K and NB-AMR (Narrow Band adaptive Multi-Rate, self-adapting multi-rate narrowband coding) arrowband
SD business, code efficiency is 12.2K, and narrow band data bag size is generally 35~47Byte.For VOIP business data packets week
The characteristics of phase property is reached, each data package size is relatively fixed, uses SPS, to quiet to VOIP activation phase initial transmitted data packet
SID (Silence Insertion Descriptor, the Jing Yin insertion description) bags and re-transmission bag of silent phase use dynamic dispatching.
During SPS, in base station side, after VOIP is carried and set up, by PDCP (Packet Data
Convergence Protocol, PDCP) layer detection up-downgoing packet size, judge the class of packet
Type (NB-AMR, WB-AMR or the phonetic matrix that can not be recognized) and by bag size, whether enter wardrobe compression etc. information pass through interface
Message informing MAC layer (Media Access Control, medium access control), MAC layer carries out SPS according to the information for receiving
Resource allocation.Resource allocation information is sent to UE (User Equipment, user equipment) by base station, and UE preserves current resource
Distribution information, every the fixed cycle the enterprising row data in identical running time-frequency resource position transmission or reception.
During dynamic dispatching, when the data arrives, resource is distributed for counting in base station temporarily by resource allocation signal
According to transmission, the resource distributed is served only for the transmission of current data.
In SPS resource allocation process, base station it needs to be determined that PRB (the Physical Resource Block, physics of distribution
Resource Block) number, in the prior art, base station pass through CQI (Channel Quality Indicator, cqi)
To determine the corresponding MCS of the UE (Modulation and Coding Scheme, modulation and coding strategy) grade, according to MCS
Grade searches 3GPP (3rd Generation Partnership Project, third generation partner program) 36.213 agreements
In table, for downlink resource distribution, according to MCS multi-level lookup table 7.1.7.1-1, find corresponding TBS Index
(Transport Block Size Index, transport block size index)；For ascending resource distribution, searched according to MCS grades
Table 8.6.1-1, finds corresponding TBS Index；According to the TBS Index for finding and the data package size look-up table for receiving
7.1.7.2.1-1, the TB size not less than above-mentioned data package size are searched in the corresponding columns of TBS Index for finding
Closest to the TB size of above-mentioned downlink data packet size in (Transport Block Size, transport block size), according to determination
The TB size for going out, find corresponding PRB numbers, wherein, the data volume of each SPS scheduling is a packet and reaches the cycle
The data package size for receiving.For example：In downlink resource distribution, current MCS grades are 7, and the 7.1.7.1-1 that tables look-up obtains correspondence
TBS Index be 7, the data package size arrived further according to downlink reception is 345bits, look-up table 7.1.7.2.1-1, obtains right
The TB size for answering are 472bits, and during TBS Index are 7 column, the corresponding PRB numbers of 472bits are 4, i.e., when PRB numbers are
The packet for receiving can be carried when 4.
It is visible by foregoing description, in existing SPS resource allocation methods, simply consider the big of the packet that receives
It is small, do not consider that packet reaches cycle and SPS cycles.The PRB numbers determined by prior art are carried out data transmission, in number
During according to the bag arrival cycle less than SPS cycles, the packet that SPS cycle will can not receive all is transferred out, remaining
Packet can be accumulated in the buffer, in turn result in the time delay of packet, reduce the quality of speech business.
