Data transmission method

Abstract

The invention discloses a data transmission method, which comprises, in the data transmitting process, the base station chooses resource allocation mode according to the down going service data transmission characteristics between the base station and a terminal and informs the chosen resource allocation mode to the terminal; the terminal chooses receiving occasions according to the resource allocation mode chosen by the base station so that when the receiving occasion comes, the terminal can receive the data from the base station; wherein, when the down going service data transmission between the base station and the terminal has cyclophysis, the base station chooses the cyclic resource allocation mode, in other words, the cyclic resource allocation message is sent to the terminal only when the down going resource is allocated for the first time. The cyclic resource allocation message includes cyclic resource allocation mark and resource allocation locating information and the resource of the resource allocation locating information mark is at least two times as much as the resource needed by the terminal.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a data transmission method. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services to a terminal. The base station communicates with the terminal through the uplink and downlink. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a data transmission system using base station scheduling control, the scheduling and allocation of all system resources is usually performed by the base station, for example, the resource allocation of the base station for downlink transmission and the resources available for the termin...

Problems solved by technology

[0004] In a traditional wireless communication system, every time the base station transmits data to the terminal or the terminal wants to send data to the base station, the base station needs to send a resource allocation control overhead message to the terminal immediately, which will waste valuable system resources and reduce system efficiency.
