Embodiment Construction

[0052] The technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] In the embodiment of the present invention, in order to enable the terminal to receive scheduling messages such as contention resolution messages issued by the base station in a timely manner, so as to use the resources carried in the scheduling messages to send uplink data in a timely manner, preferably, synchronous adaptive HARQ is introduced into the scheduling messages The transmission process, that is, the transmission of scheduling messages based on synchronous adaptive HARQ control, on the one hand, can save the signaling overhead of scheduling messages; upstream data.

[0054] see figure 2 , figure 2 It is a flowchart of a method for sending a downlink scheduling message in an embodiment of the present invention, and the process may include the following steps:

[0055] Step 201, the base stati...

Abstract

The embodiment of the invention provides a method for transmitting a downward dispatching message, which comprises that: A. a dispatching message carrying resource instruction information allocated to a terminal is transmitted to the terminal by a base station through a downward dispatching channel; resource instructed by the resource instruction information is applied to transmitting upward data through the terminal; B. if the upward data transmitted by the terminal by means of the resource are not received after the dispatching message is transmitted by the base station, the procedure A is returned to be executed before transmitting frequency of the dispatching message surpasses the largest preset frequency; if the transmitting frequency of the dispatching message is within the largest preset frequency, and the upward data transmitted by the terminal are correctly received by the base station, the flow is over. The embodiment of the invention also provides a communication system and a base station; the technical scheme provided by the embodiment of the invention can effectively shorten transmission time lapse of the upward data, promote user experience, and improve success ratio of the random access.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for sending a downlink scheduling message, a communication system and a base station. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, in order to improve resource utilization, the network side dynamically schedules resources of appropriate size for the terminal to transmit data to the terminal according to the data transmission and reception requirements of the terminal. The so-called resources may include frequency resources, time slot resources, etc., or are called time-frequency resources. [0003] In order to realize the dynamic scheduling of resources, the LTE system adopts a data channel structure different from that of the cellular mobile communication system. In the LTE system, the data channel structure includes a downlink scheduling channel and a shared data channel. Wherein, the downlink schedu...
