Embodiment Construction

[0053] In order to make the objects, technical solutions, and advantages of the present invention more clearly, the technical solutions in the embodiments of the present invention will be described in contemplation in the embodiments of the present invention, and will be described, and the embodiments described herein will be described. It is merely the embodiment of the invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0054] The embodiment of the present invention provides a downlink data scheduling configuration method, such as figure 1 As shown, the method includes:

[0055] S11, the base station sends an RRC (RADIO Resource Control, Radio Resource Control) signaling, the RRC signaling, which carries the subframe information of the application STTI (Shortened Transmission Time Interval, shortening the transmission time interv...

Abstract

The invention provides a downlink data scheduling configuration method and system, base station and user equipment.The method includes: the base station sends a wireless resource control signaling to the user's device, which brings the application of the sub -frame information with the application of the transmission time interval in the wireless resource control signaling.The user device shorten the sub -frame information of the transmission time interval based on the application, and knows that each application shorten the configuration information of the transmission time interval in the sub -frames that shorten the transmission time interval;The configuration information that shortens the transmission time interval in the frame to shorten the downlink control signaling.The present invention can support the scheduling of the transmission time interval below the child frame length, providing a shorter and delayed service for user devices.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a downlink data scheduling configuration method and system, base station, and user equipment. Background technique [0002] Currently, in the LTE (Long Term Evolution, the Long Term Evolution) system, the base station is transmitted through the DCI (Downlink Control Information, Downlink Control Information) within the subcrack, and the transmission of uplink data. Each subframe is scheduled once, TTI (Transmission Time Interval) is defined as a subframe length, i.e., 1 ms. A subframe contains two time slots, 0.5ms per time slot, for normal CP (CyclicPrefix, cyclic prefix), with seven Symbol (symbol) per time slot. DCI can be sent by PDCCH (Physical DownlinkControl Channel, physical downlink control channel), or is also sent by EPDCCH (Enhanced PhysicalDownLink Control Channel, enhanced physical downlink control channel). The PDCCH is transmitted in the contro...
