Embodiment Construction

[0155] figure 1 It is a frame diagram of a communication system involved in the embodiment of this application. like figure 1 As shown, the communication system includes: a network device 01 and a terminal device 02 . When the network device 01 is a sending device, the terminal device 02 is a receiving device, and when the terminal device 02 is a sending device, the network device 01 is a receiving device. in,

[0156] Network device: it may be the aforementioned base station, or various wireless access points, or may refer to a device in the access network that communicates with the terminal device through one or more sectors on the air interface. The base station can be used to convert received over-the-air frames to and from IP packets, acting as a router between the wireless terminal and the rest of the access network, which can include an Internet Protocol (IP) network. The base station may also coordinate attribute management for the air interface. For example, the ...

Abstract

The embodiment of the invention provides an information transmission method and communication equipment, and the method comprises the steps that first equipment generates a state report which comprises at least one first serial number domain, and each first serial number domain indicates the serial number offset of a data packet corresponding to each first serial number domain; and the first device sends the state report to a second device. According to the information transmission method and the communication equipment provided by the embodiment of the invention, the first equipment can indicate the serial number offset of the data packet through the first serial number domain of the state report and implicitly indicate the serial number of the data packet to the second equipment. Due tothe fact that the value of the serial number offset is smaller than the value of the serial number, the bit number occupied by the indicating serial number offset is smaller than the bit number occupied by the indicating serial number, and therefore expenditure of the state report can be reduced.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to an information transmission method and a communication device. Background technique [0002] In an LTE communication system, a Radio Link Control (Radio Link Control, RLC) layer is located between a Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP) layer and a Media Access Control (Media Access Control, MAC) layer. Wherein, the function of the RLC layer is implemented by the RLC entity. When the sending device and the receiving device perform data processing, the data received by the RLC entity from the MAC layer, or the data sent by the RLC entity to the MAC layer is called an RLC protocol data unit (Protocol Data Unit, PDU). Wherein, the RLC PDU includes: RLC data PDU and RLC control PDU. The RLC control PDU includes: a status protocol data unit (STATUS Protocol Data Unit, STATUS PDU). [0003] In the prior art, when the R...
