Embodiment Construction

[0053] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as figure 1 As shown, the present embodiment provides a data sending and receiving channel, the data sending and receiving channel 110, one end is connected to the high-level information link 120, and the other end is connected to the physical channel 130 of the air interface, which is used to make the high-level information link through N times of mapping The high-level information data source of the road 120 is converted into physical channel data suitable for transmission by the physical channel 130, and the physical channel data is carried on a preset carrier; wherein, the N is 1 or 2.

[0055] In this embodiment, the data sending and receiving channel can be a data transmission channel with data sending and receiving capabilities, for example, it can receive data from the high-level informat...

Abstract

The embodiment of the invention discloses a data receiving and sending channel, a data transmission method and device. One end of the data receiving and sending channel is connected with a high-levelinformation link, and the other end is connected with an air interface physical channel, used for converting high-level information data sources of the high-level information link into the physical channel data suitable for the transmission of the physical channel through N times of mapping, and loading the physical channel data on a preset carrier; wherein the N is 1 or 2. According to the embodiment of the invention, by means of the data receiving and sending channel, and the data transmission method and device, the high-level information of the high-level information link can be converted to the physical channel data suitable for the transmission at the physical channel only through the data mapping of 1 or 2 times, therefore, the number of the data mapping is reduced, the conversion ofthe high-level information to the physical channel data is simplified, and the efficiency and real time of the data conversion are improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a data sending and receiving channel, a data transmission method and a device. Background technique [0002] In the fourth-generation mobile communication 4G access network protocol stack, radio bearer (Radio Bearer, RB) has become the main body of user data bearer. The RB is oriented to the IP layer connection Enhanced Radio Access Bearer (E-RAB), and oriented to the air interface to connect the Logical Channel and the Transport Channel. [0003] RB has data processing functions such as header compression / decompression, security, packetization / unpacketization, etc. In terms of mobility, security depends on the air interface physical cell. [0004] RBs need to be mapped to logical channels, logical channels are mapped to transport channels, transport channels are mapped to physical channels to reach the air interface, and other multi-level mapping methods. [0005...
