Abstract
The invention provides a semi-persistent scheduling (SPS) resource allocation method and a base station. The SPS resource allocation method is that the base station receives data packets sent during voice communication of UE (user equipment); the base station determines MCS (modulation and coding scheme) level and determines packet information of the data packets according to the received data packets, particularly, the MCS level is determined by the base station according to CQI (channel quality indicator) of a channel which is used for the UE to send the data packets, and the packet information contains packet size; further, the base station determines data volume of each SPS according to the first formula that the data volume of each SPS=min{preset maximum data volume of the SPS, the packet size*[SPS cycle/data packet arrival cycle]}; furthermore, the base station determines quantity of PRB (physical resource blocks) according to the data volume of each SPS and the MCS level so as to allow the UE to transmit the data packets according to the quantity of the PRB. By the SPS allocation method and the base station, time delay of the data packets can be reduced while voice service quality can be improved.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of distribution method and base station of half-persistence scheduling resources.
Background technology
In a communications system, LTE (Long Term Evolution, Long Term Evolution) adopt shared resource allocation scheduling system, the scheduling method that current LTE determines is divided into two kinds: semi-continuous scheduling (Semi-Persistent Scheduling is called for short SPS) and dynamic dispatching.
In LTE system, eliminate the voice service of whole circuit domain, adopt VOIP (Voice over Internet Protocol, the networking telephone) business of data field.In VOIP business, speech coder is according to fixed cycle output grouping, and as shown in Figure 1, Fig. 1 shows VOIP business data transmission schematic diagram.In transient state (without the call) stage, do not have voice packet to need scheduling, now can carry out the dynamic dispatching of other business; In talk spurt state (call) stage; user converses, and usually can produce a packet by every 20ms, in Silent period (call interval) stage; theory only has 160ms background sound symbol once, does not have speech data to dispatch.VOIP packet is classified according to type of coding, the most frequently used is: WB-AMR (Wide Band adaptive Multi-Rate, AMR-WB is encoded) broadband high definition business, code efficiency is 23.85K and NB-AMR (Narrow Band adaptive Multi-Rate, self-adapting multi-rate narrowband is encoded) arrowband SD business, code efficiency is 12.2K, and narrow band data bag size is generally 35 ~ 47Byte.For VOIP business data packet periodically arrival, the relatively-stationary feature of each data package size, SPS is adopted to VOIP active period initial transmitted data packet, to SID (Silence Insertion Descriptor, quiet insertion describes) bag and the retransmission packet employing dynamic dispatching of quiet period.
In SPS process, in base station side, after VOIP carrying is set up, by PDCP (Packet Data Convergence Protocol, PDCP) layer detect up-downgoing packet size, judge packet type (NB-AMR, WB-AMR, the phonetic matrix that maybe can not identify) and by bag size, whether carry out the information such as head compression by interfac message notification MAC layer (Media Access Control, medium access control), MAC layer carries out SPS Resourse Distribute according to the information received.Resource allocation information is sent to UE (User Equipment, subscriber equipment) by base station, and UE preserves current resource allocation information, every the fixing cycle in the transmission of the enterprising row data in identical running time-frequency resource position or reception.
In dynamic dispatching process, when the data arrives, base station is used for transfer of data by the interim Resources allocation of resource allocation signal, and the resource of distributing is only for the transmission of current data.
At SPS resource allocation process, base station needs PRB (the Physical Resource Block determining to distribute, Physical Resource Block) number, in prior art, base station is by CQI (Channel Quality Indicator, cqi) determine MCS (the Modulation andCoding Scheme that this UE is corresponding, modulation and coding strategy) grade, 3GPP (3rd Generation Partnership Project is searched according to MCS grade, third generation partner program) table in 36.213 agreements, distribute for downlink resource, according to MCS multi-level lookup table 7.1.7.1-1, find corresponding TBS Index (Transport Block Size Index, transport block size index), distribute for ascending resource, according to MCS multi-level lookup table 8.6.1-1, find corresponding TBS Index, according to the TBS Index found and the data package size look-up table 7.1.7.2.1-1 received, TB size (the Transport Block Size being not less than above-mentioned data package size is searched in the hurdle that the TBS Index found is corresponding, transmission block size) in closest to the TB size of above-mentioned downlink data packet size, according to the TB size determined, find corresponding PRB number, wherein, the data volume of each SPS scheduling is a packet and arrives the data package size that the cycle receives.Such as: during downlink resource distributes, current MCS grade is 7, it is 7 that the 7.1.7.1-1 that tables look-up obtains corresponding TBS Index, again according to downlink reception to data package size be 345bits, look-up table 7.1.7.2.1-1, to obtain corresponding TB size be 472bits, TBS Index is in the hurdle of 7, the PRB number that 472bits is corresponding is 4, namely can carry the packet received when PRB number is 4.
Visible by foregoing description, in existing SPS resource allocation methods, just consider the size of the packet received, do not consider that packet arrives cycle and SPS cycle.The PRB number determined by prior art carries out transfer of data, packet arrive the cycle be less than SPS cycle time, the packet received can not all transfer out by a SPS cycle, remaining packet can accumulate in the buffer, and then cause the time delay of packet, reduce the quality of speech business.
