Rlc数据包传输的确认方法及rlc am实体发送方

Method for acknowledging transmission of RLC (Radio Link Control) data packet and RLC AM (Acknowledge Mode) entity sender

Abstract

The invention provides a method for acknowledging transmission of an RLC (Radio Link Control) data packet and an RLC AM (Acknowledge Mode) entity sender. According to the embodiment of the invention, the RLC AM entity sender sends the RLC data packet comprising first indication information to an RLC AM entity receiver by a sender MAC (Media Access Control) entity and a receiver MAC entity so as to indicate the RLC AM entity receiver to forbid to feed back an acknowledgment message of the RLC data packet, and by receiving a local acknowledgment message of the RLC data packet, which is fed back by the sender MAC entity, the RLC AM entity sender can acknowledge whether transmission of the transmission packet is successful. The problem of generating great signaling overheads due to transmission of the acknowledgment message corresponding to the RLC data packet in the prior art can be avoided, so that the signaling overheads are reduced, and transmission resources are saved.
本发明提供一种RLC数据包传输的确认方法及RLC AM实体发送方。本发明实施例RLC AM实体发送方通过发送方MAC实体、接收方MAC实体向RLC AM实体接收方发送包含第一指示信息的RLC数据包,指示所述RLC AM实体接收方禁止反馈所述RLC数据包的确认信息,以及通过接收所述发送方MAC实体反馈的所述RLC数据包的本地确认信息,使得RLC AM实体发送方能够确认所述传输包的传输是否成功,能够避免现有技术中由于传输RLC数据包对应的确认信息而产生很多信令开销的问题,从而减少了信令开销,节省了传输资源。
