Method for Acknowledging RLC Data Packet Transmission and RLC AM Entity Sender

Abstract

The present invention provides a method for acknowledging RLC data packet transmission and an RLC AM entity sender. In embodiments of the present invention, an RLC AM entity sender sends an RLC data packet, which includes first indication information, to an RLC AM entity receiver through a sender MAC entity and a receiver MAC entity. The RLC AM entity receiver is instructed not to feed back acknowledgment information of the RLC data packet. Local acknowledgment information of the RLC data packet that is fed back by the sender MAC entity is received, so that the RLC AM entity sender can determine whether the transmission of the transmitted packet is successful.

Description

[0001]This application is a continuation of International Application No. PCT / CN2012 / 085237, filed on Nov. 26, 2012, which claims priority to Chinese Patent Application No. 201110378143.2, filed on Nov. 24, 2011 and Chinese Patent Application No. 201210021900.5, filed on Jan. 31, 2012, all of which are hereby incorporated by reference in their entireties.TECHNICAL FIELD[0002]The present invention relates to a communications technology and, in particular embodiments to a method for acknowledging radio link control data packet transmission and an RLC acknowledgment mode entity sender.BACKGROUND[0003]With the development of communications technologies, an increasing number of intelligent applications, such as instant messaging software and the MicroBlog, are integrated on a user equipment. In the foregoing intelligent applications, in a transmission process of an RLC data packet of the user equipment, when receiving or not receiving an RLC data packet sent by an RLC AM entity sender, a...

Benefits of technology

[0005]The present invention provides a method for acknowledging RLC data packet transmission and an RLC AM entity sender, which are used to reduce signaling overhead and save transmission resources.

[0008]It can be known from the foregoing technical solutions, in embodiments of the present invention, an RLC AM entity sender sends an RLC data packet including first indication information to an RLC AM entity receiver through a sender MAC entity and a receiver MAC entity instructs the RLC AM entity receiver not to feed back acknowledgment information of the RLC data packet and receives local acknowledgment information of the RLC data packet that is fed back by the sender MAC entity. In this way, the RLC AM entity sender can determine whether the transmission of the transmitted packet is successful. This can avoid a problem in the prior art that great signaling overhead is generated due to transmission of acknowledgment information corresponding to an RLC data packet, thereby reducing signaling overhead and saving transmission resources.

Problems solved by technology

However, in order to transmit the acknowledgment information corresponding to the RLC data packet, great signaling overhead is generated, for example, before downlink acknowledgment information is transmitted, signaling such as physical downlink control channel (PDCCH for short) scheduling information is generated.

This leads to a waste of transmission resources.
