Resource so that UE once has data transmission requests, just has resource to send dispatch request SR to base station at once, and every UE each
Subframe (Subframe) has the opportunity to send SR, and base station receives SR, can at once distribute ascending resource and exist to the UE, but the method
The caused time delay of interaction twice, while reducing the effective rate of utilization of physical resource.
For exempting from scheduling method, scheduling resource is continuously exempted from the setup time of base station, UE once there are data transfer demands, just
Can exempt from scheduling resource it is direct on send, and in data carry UE identity informations (Identification, ID) for BS screen
The source of data block, the method can realize low time delay, but due to exempting from scheduling, therefore there is multi-section UE and sent out in same resource simultaneously
The possibility of data block is sent, this can cause signal overlap or conflict, in turn result in data block transfer failure, so needing multi-configuration
Exempt from scheduling resource to disperse UE to send distribution to reduce the probability for clashing, to reduce the possibility of re-transmission.In addition, using sky
Between diversity can reduce reception Block Error Rate (Receiving Block Error Rate), it is also possible to reduce retransmit possibility,
But BS arrangement spaces diversity can cause engineering difficulty and relatively costly.
To solve the above problems, the embodiment of the present invention sets up communication connection respectively by with multiple base stations, and many with described
At least one of at least one of individual base station base station is set up and exempts from the communication connection of scheduling method, and then with the multiple base station
