摘要

The present application discloses methods and devices for determining a downlink resource set and sending resource position information, and particularly relates to a method for determining, by a terminal, a downlink control channel resource set, a method for sending, by a base station, a position related to a downlink control channel resource set, and related devices. A terminal obtains, in a predefined manner and/or by receiving a notification of a base station, a frequency domain position and a time domain position of a downlink control channel resource set corresponding to the terminal, so as to determine that the downlink control channel resource set corresponding to the terminal is a third downlink control channel resource set. The base station transmits a common downlink control channel and/or a terminal-dedicated downlink control channel on the frequency domain and time domain positions of the downlink control channel resource set determined by the terminal.

說明書

The mobile Internet is overthrowing the traditional mobile communication service modes, providing its subscribers with an unanticipated use experience, and profoundly influencing various aspects in our working and life. In mobile communication, as more and more demands for new services are emerging constantly, there is a demand for higher performance of future mobile communication systems, e.g., a higher peak rate, a higher user experienced rate, a shorter delay, high reliability, higher spectrum efficiency, higher energy consumption efficiency, etc., and a demand for supporting more accessing user equipments, and various types of services. A terminal may need to support a number of transmission modes, various scenarios, and more types of services concurrently. The complexity and power consumption of the terminal side is required to be lowered. If the terminal needs to listen to a downlink control channel throughout a transmission bandwidth, then there will be a great challenge to energy consumption control of the terminal, and a delay at the terminal side will be increased. Moreover in order to improve the utilization ratio of resources, and to satisfy some future application scenarios (e.g., Inter-Cell Interference Coordination (ICIC)), a transmission resource of a downlink control channel shall be configured more flexibly.
