201st, eNodeB determines multicasting schedule, it is determined that the multicast group of multicasting schedule will be used, eNodeB will use multicasting schedule mechanism to multiple UE in multicast group.
202nd, the multiple UEs that include of the eNodeB into multicast group are sent in measurement report configuration parameter, the measurement report configuration parameter comprising measurement target and measurement report condition；Wherein, target, namely network parameter to be measured, e.g. Reference Signal Received Power or Reference Signal Received Quality are measured；Measurement report condition is, for example,：When measuring desired value and being higher than some specific threshold reporting measurement reports, when measuring desired value and being less than some specific threshold reporting measurement reports, periodic report measurement report or report survey immediately
Amount report.
203rd, when UE judges that UE prepares to send the network parameter measurement report for reflecting wireless communication quality to eNodeB when meeting measurement report report condition.
204th, UE sends network parameter measurement report to eNodeB.
205, the network parameter measurement report that multiple UE that eNodeB receptions multicast group includes are sent respectively, according to each network parameter measurement report, a target UE for needing to send the feedback information for whether being properly received multicast packet after multicast packet is received is determined in multiple UE, in practice, eNodeB can select the worst network parameter measurement report of a reflection wireless communication quality, the corresponding UE of the network parameter measurement report is defined as target UE, for example, eNodeB is according to each network parameter measurement report, it is UE1 to determine target UE.
206th, eNodeB sends a notification message to UE1, and the notification message is used to indicate that UE1 is whether the feedback channel resources return that UE1 is configured is properly received the feedback information of multicast packet using eNodeB.In practice, eNodeB is that UE1 configures feedback channel resources and indicates that the implementation that UE1 returns to feedback information using the feedback channel resources can at least include following three kinds of modes：
Implementation 1:ENodeB it is determined that target UE be UE1 after, feedback channel resources are configured for UE1, and in the positional information for including the feedback channel resources for UE1 configurations to the UE1 notification messages sent, and the notification message is used for the feedback information for indicating whether UE1 is properly received multicast packet using the feedback channel resources for being allocated to UE1 to eNodeB returns.
Implementation 2:ENodeB it is determined that target UE be UE1 after, the positional information of feedback channel resources is configured for UE1, and include to the UE1 notification messages sent for the positional information of the UE1 feedback channel resources configured, optionally, the configured information for being used to indicate that UE1 returns to the feedback information for whether being properly received multicast packet using the feedback channel resources for being allocated to UE1 to eNodeB is also included in notification message.
Implementation 3:ENodeB is it is determined that be that feedback channel resources positional information is respectively configured in all UE in multicast group in advance before target UE；ENodeB determines UE1 for after target UE, sent a notification message to UE1, notification message includes the configured information for being used to indicate that UE1 returns to the feedback information for whether being properly received multicast packet using the feedback channel resources being pre-configured with to UE1 to eNodeB.
207th, multiple UE that eNodeB includes to multicast group dispatch and sent multicast packet.
208th, UE1, according to the reception condition of multicast packet, sends whether be properly received multicast packet using the feedback channel resources configured for UE1 after the multicast packet of eNodeB transmissions is received to eNodeB
Feedback information.If UE1 has been properly received multicast packet, UE1 is ACK to the eNodeB feedback informations sent on the feedback channel resources configured for it;To the eNodeB feedback informations sent it is NACK on the feedback channel resources configured for target UE if target UE reception failures.
209, eNodeB receive the feedback information that UE1 is returned on the feedback channel resources configured for UE1：If eNodeB detects NACK on the feedback channel resources configured for UE1, eNodeB determines that multicast packet sends failure, also, eNodeB needs to resend multicast packet；If eNodeB receives ACK on the feedback channel resources configured for UE1, eNodeB determines that multicast packet is sent successfully.
If the 210, eNodeB determines that multicast packet sends failure, eNodeB reschedules and sent above-mentioned multi-case data.
Multicast packet provided in an embodiment of the present invention sends processing method, by selecting a target UE from multiple UE that multicast group includes, and configure feedback channel resources for target UE, so that target UE is after the multicast packet of eNodeB transmissions is received, according to the reception condition of multicast packet, the feedback information for whether being properly received multicast packet is returned to eNodeB on the feedback channel resources configured for target UE；When eNodeB detects NACK on feedback channel resources, then determine that multicast packet sends failure, and resend multicast packet, so that, the reception feedback of multicast packet is realized with less feedback channel resources expense, the reliability of muticast data transmission is improved.
