Description
Technical field
The travelling carriage, wireless base station and the radio network controller that the present invention relates to mobile communication system and be used for this mobile communication system, wherein this mobile communication system constitutes: the data sending terminal device is be sure of signal according to sending to of sending from the Data Receiving end device, uses data channel and control channel will send data block and retransmits.
Background technology
In the past, in mobile communication system, because waiting through decline, multichannel causes the instantaneous change of received signal intensity in the Data Receiving end device, so there is following problem: the receiving quality of the receiving quality of the uplink signal of wireless base station or the down link signal of travelling carriage is deterioration significantly, and it is many to receive wrong change.
As the technology that overcomes this problem, known hybrid ARQ (HybridAuto Repeat Request is hereinafter referred to as HARQ).
As shown in Figure 1, to be Data Receiving end device (wireless base station NodeB or mobile station UE) send corresponding with the transmission data block that the is received confirmation signal (Ack or Nack) of sending to data sending terminal device (mobile station UE or wireless base station NodeB) to HARQ.
Usually, the data sending terminal device only received that expression sends that data block (for example sending data block #1) correctly received send to confirmation signal (Ack) time, send next and send data block (for example sending data block #2).
On the other hand, the data sending terminal device received that expression sends that data block can not correctly receive send to confirmation signal (Nack) time, carry out the transmission of this transmission data block once more.
And then, as shown in Figure 2, in HARQ, can carry out soft merging (soft combining).With reference to Fig. 2, the operating principle of the soft merging of simple declaration.
In step S101, the data sending terminal device sends the transmission data block of being made up of 3 (bit), and in step S102, the Data Receiving end device is implemented decoding to received transmission data block and handled.At this moment, establish the Data Receiving end device and detect reception wrong (with reference to step S103).At this, the Data Receiving end device detects formation 3 of receiving wrong transmission data block and is stored in the memory as soft judgements.
In step S104, the data sending terminal device retransmits by 3 transmission data blocks of forming, in step S105, the Data Receiving end device carries out add operation to the soft judgement position that is stored in memory with 3 that constitute received transmission data block, to improve signal to noise ratio.As a result, the Data Receiving end device does not detect the reception mistake, sends the reception success (with reference to step S106) of data block.
Have again, in HARQ, during till send to confirmation signal and return in, send the later transmission data block of data block by sending next, thereby can improve the service efficiency of Radio Link.As the straightforward procedure that is used for this, knownly stop and waiting for (stop-and-wait).With reference to Fig. 3, the operating principle that stops and waiting for of 4 processes (process) is carried out simple declaration.
As shown in Figure 3, the data sending terminal device is sending after the data block, produces time delay (timelag), up to receive this transmission data block send to confirmation signal till.In the example of Fig. 3, this time delay is more than 2 times below 3 times of delivery time of sending data block, after the timing that therefore will retransmit this transmission data block is made as 3 transmission data blocks.
At this moment, as shown in Figure 3, can be considered as 4 HARQ and move side by side, be referred to as stopping and waiting for of 4 processes.
Owing to send to the time delay till the confirmation signal or the processing delay of data sending terminal device and Data Receiving end device etc. according to the delivery time that sends data block or to reception, decision is several N of the HARQ of action side by side, so be called stopping and waiting for (N Process Stop and Wait) of N process.
(non-patent literature 1) Keiji Tachikawa prison is repaiied the kind Co., Ltd. of " W-CDMA mobile communication " ball
(non-patent literature 2) 3GPP TR25.896 v6.0.0
Yet, though HARQ can send reliably to the Data Receiving end device aspect the data block transmission superior, (when sending data block via up link is down link but because with reciprocal Radio Link, when sending data block via down link is up link) send to confirmation signal (Ack or Nack), so there is the problem that the load in the Radio Link increases in this opposite direction.
Have again, known: in mobile communication system, the technology (decision sends the technology of data block size) of the transfer rate that waits control signal according to the idle condition or the radio quality of Radio Link.
For example, as the system that adopts this technology, be known in and carry out standardized " HSDPA (High Speed Downlink Packet Access) " or " EUL (enhanced uplink: EnhancedUplink) " among the 3GPP.The predetermined HARQ that adopts in this system is arranged again.
In this system, constitute the Data Receiving end device no matter how send the data block size, send to confirmation signal for 1 that transmits expression Ack or Nack.
That is,, represent that then 1 load and effect of sending to confirmation signal of Ack or Nack offsets,, represent that then 1 load of sending to confirmation signal of Ack or Nack becomes the situation that is not allowed to if it is slight greatly to send data block if it is big to send the data block size.
Have again, under the situation that the summation of the transmission data block size in having considered certain Radio Link equates, when each transmission data block size is big, only send the transmission data block of a little, therefore only produce the confirmation signal of sending to of a little.
Yet, send under the big slight situation of data block at each, owing to can send a lot of transmission data blocks,, there are problems such as no specific electric load change in the reciprocal Radio Link is big so can send a lot of confirmation signals of sending to.
Also have, as mentioned above, the load in the reciprocal Radio Link exists with ... the crowding of reciprocal Radio Link to the influence that mobile communication system causes.
Promptly, there is following problem: under the little situation of the crowding of reciprocal Radio Link, load in the reciprocal Radio Link is little to the influence of mobile communication system, but under the big situation of the crowding of reciprocal Radio Link, the load in the reciprocal Radio Link becomes big to the influence of mobile communication system.
