Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
Embodiment one
The flow diagram for the method that data retransmit is realized in the group service that Fig. 1 provides for the embodiment of the present invention one, such as
Shown in Fig. 1, in the group service data retransmit method the following steps are included:
101, the base station period issues group's signaling by group, so that the monitor terminal in group is obtained according to group's signaling
Feedback resources in physical uplink control channel PUCCH.
Wherein, the monitor terminal that the feedback resources are only used in the group does not parse what the base station issued correctly
Indicate that the monitor terminal in the group is in uplink motor synchronizing shape to the non-response NACK of the base station feedback when data packet
State.
Specifically, base station indicates that the monitor terminal in group obtains the institute in PUCCH by issuing group's signaling to group
State feedback resources.It include at least one monitor terminal in general group.Wherein, do not parse what base station issued correctly in group
The monitor terminal of data packet indicates on the feedback resources to base station feedback NACK.
Base station issues the group's signaling for carrying configuration information in the period, so that monitor terminal exists according to configuration information
Feedback resources described in static configuration in PUCCH.
