Title: DOWNLINK INFORMATION TRANSMISSION AND RECEPTION METHOD AND DEVICE
Abstract:
Disclosed are a downlink information transmission and reception method and device. The method comprises: determining one or more search spaces comprising one or more short physical downlink control channels (sPDCCHs) and used for receiving downlink control information, wherein the search spaces comprise at least one of the following resources: some of the resources in a subframe, some of the resources in a short transmission time interval (sTTI) and some of the resources in an orthogonal frequency division multiplexing (OFDM) symbol; and receiving the downlink control information by means of the one or more sPDCCHs comprised in the determined one or more search spaces. The present invention solves the problem in the related art that a downlink information processing method cannot support an sTTI of a new granularity, thereby ensuring a delayed communication requirement.
