Embodiment Construction

[0059]In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

[0060] (1) In the embodiments of this application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand their meanings.

[0061] (2) The term "multiple" in the embodiments of the present application refers to two or more, and other quantifiers are similar.

[0062] (3) "And / or", which describes the association relationship of associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists independently. Happening. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further...

Abstract

The embodiment of the invention relates to a method and equipment for data transmission, which are used for solving the problem of no clear scheme for data transmission after cache initialization or reset due to asynchronous cache in the prior art. According to the embodiment of the invention, a network side device decompresses a received UDC compressed data packet by decompressing a target compression dictionary in a cache; And the terminal compresses the data packet needing to be sent through the target compression dictionary in the compression cache to obtain a UDC compressed data packet and sends the UDC compressed data packet. As the network side device and the terminal can perform decompression operation and compression through the target compression dictionary, the success rate of data transmission is improved after cache initialization or reset due to asynchronous cache; The transmission efficiency is further improved, and air interface resources are saved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for data transmission. Background technique [0002] In LTE / LTE-A (Long Term Evolution, long-term evolution) / LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade), the terminal can be configured with a UDC (UL data compression, uplink data compression) function. Uplink data compression means that the terminal compresses the uplink data or signaling at Layer 2, and the base station side decompresses the compressed data at the corresponding protocol layer. The purpose is to save the amount of data transmitted over the air interface, save uplink resources, and improve transmission efficiency. [0003] In order to improve the compression rate, the terminal and the base station maintain buffers independently according to the data sent and received. In general, two types of content can be stored in the cache: one is pre-configured...
