Abstract: A method and apparatus for transmitting downlink control information. In the present invention, transmitted downlink control information at least comprises one or more of the following information fields: a first information field used for indicating the frequency domain resources occupied by the data resources scheduled by the DCI, a second information field used for indicating the time frequency resources occupied by the data resources scheduled by the DCI, and a third information field used for indicating the scheduled N users. As the resource size occupied by the transmission resources in the frequency domain and/or in the time domain is indicated by means of the downlink control information, transmission of downlink control information can be implemented in flexible resource allocation scenarios having variable transmission time intervals.

Abstract: The present application provides a method and apparatus for configuring a transmission bandwidth, and a device, for accelerating an activation speed of a carrier/BWP, reducing waiting time of a UE, and saving power consumption of the UE. The method comprises: determining a first carrier/first BWP; and sending a PDCCH to a user terminal UE by means of a second carrier/second BWP, the PDCCH being used for bearing instruction information for activating the first carrier/first BWP and sending a reference signal over the first carrier/first BWP, so that the UE may activate the first carrier/first BWP and receive the reference signal, wherein the reference signal is used by the UE for performing channel measurement and synchronous tracking on the first carrier/first BWP.

Abstract: Disclosed are a data transmission method and device, and a signal feedback method and device. The data transmission method comprises: after executing an LBT operation in a direction corresponding to at least one beam, a base station sending to a terminal a channel occupation request signal to request channel occupation; and after receiving a signal indicating that a channel is allowed to be occupied, the base station transmitting data on the beam sending the channel occupation request signal. The signal feedback method comprises: the terminal receiving the channel occupation request signal sent to the terminal by the base station on the at least one beam, wherein the channel occupation request signal is a signal for requesting channel occupation; and after correctly receiving the channel occupation request signal, the terminal feeding back, on the beam on which the signal is received, to the base station the signal indicating that the channel is allowed to be occupied. By using the present application, the problem of data transmission interference caused by an interfering node can be avoided.

Abstract: Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, and the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, and the random access response message includes downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.

Abstract: The present application discloses a resource selection method, a data transmission method and a device, relating to the field of communication technology. In the embodiment of the present application, in a case where it is determined that the resource multiplexing mode of the first link and the second link is frequency division multiplexing, by judging whether the selected link is allowed to select a resource that overlaps with the selected resource on another link in the time domain, it may further determine whether to select a resource that does not overlap with the selected resource on another link in the time domain to transmit a service packet to be sent, such that it can also be adjusted according to actual needs based on the pre-configuration, thereby greatly increasing the flexibility of resource selection and the efficiency of spectrum use.
