20120034948 | METHOD, DEVICE, AND SYSTEM FOR REGULATING POWER CONSUMPTION - A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user's normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed so that the number of a downstream reference signal is dynamically adjusted. This reduces the power consumption of the network device. | 02-09-2012 |

20150195821 | METHOD FOR TRANSMITTING DOWNLINK CONTROL INFORMATION, NETWORK SIDE DEVICE, AND USER EQUIPMENT - The present invention provides a method for transmitting downlink control information, a network side device, and a user equipment. The method includes: selecting, by a network side device, a aggregation level of a physical control channel set in a transmission subframe, and selecting the number of physical control channel candidates corresponding to the aggregation level according to the aggregation level; and sending, by the network side, downlink control information on a physical control channel candidate corresponding to the selected number. The times that blind detection is performed corresponding to the aggregation level corresponds to the number of physical control channel candidates, and therefore, when the number of physical control channel candidates is determined, the times that blind detection is performed is determined, so that the network side device and the user equipment can communicate with each other without increasing the times that blind detection is performed. | 07-09-2015 |
