Downlink control information sending method and device, and downlink control information receiving method and device
First Claim
1. A downlink control information sending method, comprising:
- sending, by a base station device, downlink control information (DCI) on a physical downlink control channel (PDCCH) of a downlink subframe, wherein the DCI is used to instruct user equipment (UE) to receive physical downlink shared channel (PDSCH) information in an uplink subframe; and
sending, by the base station device, the PDSCH information in the uplink subframe.

Abstract
The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.
