At LTE(Long Term Evolution) in system, UE(subscriber equipment in resting state (Dormant)) there is same eNB(evolution base station) between RRC(Radio Resource Control, Radio Resource is controlled) connect and the radio bearer of having set up, but for the object of power saving has activated DRX(discontinuous reception), be currently in temporary transient unactivated state.As shown in Figure 1, be the state flow path switch figure under LTE system in prior art.This figure is converted to example with the state of the upstream data triggering of synchronous regime UE, comprises the following steps:
Step S101, next SR(Scheduling Request, dispatch request are waited in UE time delay) opportunity.
Step S102, UE sends dispatch request to eNB.
Step S103, eNB receives this dispatch request, and decoding is processed.
Step S104, eNB is this UE allocation schedule mandate (Scheduling Grant).
Step S105, UE processes.
Step S106, UE according to scheduling authorization result to eNB transmit ascending data.
In this state flow path switch, change required Delay computation as follows:
Wherein, according to minimum time delay and cycle, and do not consider error of transmission, the optimum delay estimation of each several part is as follows, and the final time delay altogether of calculating is 11.5ms.
| Step | Describe | Time [millisecond] |
| 1 | Average waiting time delay (5 milliseconds of PUCCH cycles) to next SR | 2.5 |
| 2 | UE sends dispatch request (SR:Scheduling Request) | 1 |
| 3 | The request of eNB decoding scheduling allocation schedule mandate (Scheduling Grant) | 3 |
| 4 | Transmitting and scheduling mandate | 1 |
| 5 | UE processing delay (decoding scheduling mandate+L1 encodes to upstream data) | 3 |
| 6 | Transmit ascending data | 1 |
| ? | Time delay altogether | 11.5 |
Yet the target of current 3GPP LTE-A is to get rid of the impact of DRX cycle, be 10 milliseconds the change-over time from resting state to state of activation.For this target, need to make further improvements existing state conversion process, the transfer of data based on competition (CB:Contention Based) has therefore been proposed.The main thought of transmission method based on competition is transmit ascending data on the ascending resource that can be allowed to competing while there is no special-purpose resource when UE is current.As shown in Figure 2, be the state flow path switch figure based on competition transmission under LTE-A system in prior art, comprise the following steps:
Step 201, the competitive resource that eNB notice UE can use.
