Title:
METHOD, DEVICE, AND SYSTEM FOR TRANSMITTING DOWNLINK CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/194022
Kind Code:
A1
Abstract:
Provided in embodiments of the present disclosure are a method, device, and system for transmitting downlink control information. The method comprises: carrying, by means of at least one from a legacy PDCCH, EPDCCH, and sPDCCH, DCI of UE for scheduling an sTTI; and sending to a terminal the carried DCI, wherein service channels to be scheduled by the DCI comprises at least one of the following: only service channels within the sTTI; service channels within the sTTI or service channels within a TTI of 1 ms; and service channels within the sTTI and service channels within a TTI of 1 ms. The embodiments of the present disclosure solve the problem of the related art in which lack of support for a short TTI and downlink control information of related service scheduling thereof exists in low-latency communication scenarios, and provide implementation schemes to support short TTI scheduling and related service scheduling with variable TTI lengths, thus ensuring that latency-related communication requirements are met.
