Abstract
The present invention discloses a method for controlling the transmission conflict and the system, which comprises the following steps: judging whether the first and second transmissions will generate conflict at the predefined distributed resource; sending the control signalling containing the early warning parameter to the terminal which initiates the first transmission and the terminal which initiates the second transmission at the first time before the coming of the conflict, the early warning parameter is used to indicate the forecasted time when the first transmission and the second transmission generate conflict at the predefined distributed resource; and sending the control signalling of distributing the new resource to the terminal corresponding to the second transmission at the second time which is after the first time and before the coming of the conflict. The early warning parameter is arranged to indicate the conflict which is likely to generate, the base station and the terminal only do alternation of the control signalling when the conflict which is likely to generate comes, aiming at the scheme of the prior art that the control signalling is transmitted before each retransmission, the invention reduces the spending of the control signalling, increases the availability of the resource and reduces the treating complexity of the terminal.
Description
Technical field
The present invention relates to transmission collision control method and system.
Background technology
In Long Term Evolution (LTE) system of the 3rd third-generation mobile communication that 3GPP standardization body is defining,, the automatic re-send request may transmission of synchronized mixes, continuous dispatching and not isometric transmission time mechanism have been introduced in order to reduce the expense of control signaling; Adapt to new flexibility in order to increase mixed automatic retransmission request transmission mechanism, introduced the automatic re-send request may transmission of ADAPTIVE MIXED again to variation.
Wherein, the automatic re-send request may transmission of synchronized mixes is meant that the moment of the retransmission operation of mixed automatic retransmission request transmission process is predefined, does not need explicit signaling to indicate the sequence number of mixed automatic retransmission request transmission process before re-transmission.
Continuous dispatching is meant the characteristics that arrive according to some business datum, periodically for it distributes fixing resource, than dynamic dispatching, the resource allocation of this scheduling mode is predefined, no longer need to control the signaling indication before each resource allocation, thereby reduced the expense of control signaling.
Not isometric transmission time technology is meant that the transmission time of each mixed automatic retransmission request transmission process is not isometric, the resource continuous time that promptly each transmission is distributed is not isometric, with respect to the isometric transmission time, the longer transmission time also can reach the purpose that reduces the control signaling consumption.
The transmission of the automatic re-send request may of ADAPTIVE MIXED is meant that transmitting terminal can owing to reasons such as changes in channel characteristics, change part or all of transmission property when each the re-transmission, so needed the control signaling of being correlated with before each the re-transmission.Wherein, transmission property comprise at least modulation system, resource allocation and transmission duration one of them.
In present LTE system, tend in the automatic re-send request may transmission of up employing synchronized mixes.If but adopted the continuous dispatching and the mechanism in isometric transmission time not simultaneously, could produce following problem:
As shown in Figure 1, the cycle of continuous dispatching 1 ' is 9 subframes.The automatic re-send request may of synchronized mixes transmission 2 ' is carried out initial transmission the 4th subframe, and retransmit interval is 2 subframes, if there be the 1st, 2 re-transmission, will occur in the 7th and the 10th subframe respectively.Because there is continuous dispatching 1 ' in the 10th subframe, so the 2nd re-transmission of the automatic re-send request may transmission 2 ' of synchronized mixes will clash with continuous dispatching 1 '.
As shown in Figure 2, the transmission time length that the automatic re-send request may transmission 3 ' transmission of first synchronized mixes is adopted is 1 subframe, and the transmission time length that the automatic re-send request may transmission 4 ' transmission of second synchronized mixes is adopted is two subframes.The automatic re-send request may of first synchronized mixes transmission 3 ' is carried out initial transmission the 1st subframe, and retransmit interval is 6 subframes; The automatic re-send request may of second synchronized mixes transmission 4 ' is carried out initial transmission the 4th, 5 subframe, and retransmit interval is 6 subframes.Then retransmit for the 3rd time of the automatic re-send request may transmission 3 ' of first synchronized mixes and will clash the 19th subframe with the 2nd re-transmission of the automatic re-send request may transmission 4 ' of second synchronized mixes.
In order to overcome the above problems, existing scheme proposes to adopt the automatic re-send request may transmission of self adaptation synchronized mixes, before the automatic re-send request may transmission of promptly each synchronized mixes retransmits, all introduces relevant control signaling.When clashing, change the resource location that the automatic re-send request may transmission of synchronized mixes retransmits by the control signaling, to solve imminent conflict.
For example, in Fig. 1, when the 2nd time of the automatic re-send request may of synchronized mixes transmission 2 ' retransmits and continuous dispatching 1 ' when clashing, the automatic re-send request may transmission 2 ' transmission of the control signaling indication synchronized mixes that retransmits for the 2nd time adopts the resource different with continuous dispatching 1 ' to carry out, and has so just avoided the collision of the two.
When conflict is about to take place, indicate the transmission of the automatic re-send request may of one of them synchronized mixes to retransmit by the control signaling and adopt and the different resource of the automatic re-send request may transmission of another synchronized mixes, can be applied to separate the conflict between transmitting of the automatic re-send request may of synchronized mixes that the never isometric transmission time causes equally.
Adopt the automatic re-send request may transmission plan of self adaptation synchronized mixes to solve above-mentioned conflict, the base station need send the control corresponding signaling before the automatic re-send request may transmission of each synchronized mixes retransmits, cause system control overhead to increase, reduced effective utilization rate of resource; Terminal need receive the control signaling before each the re-transmission in addition, had increased the processing complexity and the power consumption of terminal.
