Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0032] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] It should be noted that, in the embodiment of the present invention, the base station may be an ENB, a Node B, an access point (Access Point), and the like. Each base station can provide communication coverage for a specific geographic area. The term "cell (Cell)" may be a coverage area of ​​a base station, and / or a coverage area served by a base station subsystem, depending on the context in which the term is used. A base stati...

Abstract

The invention discloses a data exchange method, a device and a system thereof, which relate to the communication technical field and are invented for improving the system performance effectively. The data exchange method includes the steps that a base station acquires the processing ability of an user equipment; the base station determines a data exchange period according to the processing ability of the user equipment; the base station sends configuration information of the data exchange period to the user equipment to make the user equipment to conduct data exchange with the base station according to the data exchange period. The method, the device and the system can be used in various wireless communication systems.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data interaction method, device and system. Background technique [0002] In the Long Term Evolution LTE (Long Term Evolution) system, the scheduling of radio resources is completed by the evolved base station ENB (Evolved Node B). Therefore, when the user equipment UE (User Equipment) wants to perform data transmission, it first needs to send a scheduling request to the ENB to To obtain uplink wireless resources, when the ENB receives the UE's scheduling request, it will dynamically allocate certain time-frequency resources for the UE according to the current system resource situation, and the dynamic allocation result will be sent to the UE through corresponding control signaling, that is, Issue the uplink grant; after receiving the uplink grant, the UE will send data according to the time-frequency resources indicated by the uplink grant. [0003] Such as figure 1 As sho...
