Abstract: The present invention relates to the technical field of communications, and specifically relates to a method and device for determining the initial positions of a downlink data channel. The present invention solves the problem of determining the initial positions in the time domain of a downlink data channel when the resources occupied by a downlink control channel in the time domain are variable. The method comprises: a base station transmits to a terminal a generated indication signaling, and the terminal determines, on the basis of the received indication signaling, the time domain initial positions of the downlink data channel in L downlink TTIs. With said method, when the downlink control channel only appears in a part of the positions in a frequency domain or does not appear at all, and when the downlink control channel does not occupy the complete downlink control area in the time domain or the resources occupied by the downlink control channel in the time domain are variable, the base station can still accurately notify the terminal the time domain initial positions of the downlink data channel, so that the terminal can accurately receive downlink data, thereby enhancing the efficiency and reliability of the terminal reception of downlink data, and further enhancing the spectrum efficiency as well as the user experience.

Abstract: Disclosed in the present invention are a method and apparatus for transmitting and detecting downlink control information. The method comprises: determining a state of resource allocation in a downlink transmission time period, the resource allocation comprising allocation of at least one downlink transmission resource region; and transmitting downlink control information on a preset resource in the at least one downlink transmission resource region, the downlink control information being used for scheduling at least one terminal to perform data transmission in the downlink transmission resource region. The method also comprises: detecting the downlink control information on the preset resource in the downlink transmission time period; determining, according to the detected downlink control information, a data transmission region indicated by the downlink control information; and detecting follow-up downlink control information according to the data transmission region. By using the present invention, downlink control information can be transmitted at a fixed position in each downlink transmission time period, and multiple transmission time intervals of different lengths are supported, so that rich service types in the future can be better supported.

Abstract: Disclosed in the present invention are a method, equipment and an apparatus for indicator and downlink control channel detection, comprising: determining data which must be transmitted to a terminal in one or more transmission time intervals by means of a downlink control channel; a base station sending a command to the terminal, used to indicate that the terminal determine according to the command whether it is necessary to detect a downlink control channel in the one or more transmission time intervals. On the terminal, determining according to the command whether it is necessary to detect a downlink control channel in the one or more transmission time intervals. After using the present invention, when a base station has not scheduled a terminal, this objectively causes a terminal side to not have excess power consumption, and lowers terminal-side power consumption.

Abstract: Disclosed are a monitoring instructing and monitoring method and apparatus with a short transmission time interval. The method comprises: determining whether there is a short transmission time interval service at a network side; and instructing whether a terminal needs to monitor a downlink control channel of the short transmission time interval according to the condition whether there is a short transmission time interval service; receiving an instruction instructing whether to monitor the downlink control channel of the short transmission time interval at the terminal side; and monitoring the downlink control channel of the short transmission time interval according to the instruction. According to the present application, a terminal having a short transmission time interval capability no longer needs to monitor a downlink control channel at each short transmission time interval, and no excessive consumption and waste of energy will be caused.
