Abstract: Provided in the embodiments of the present invention are an information reporting method, a terminal and a base station. The method comprises: receiving first indication information that is configured for a terminal by a base station and is used for reporting channel state information (CSI) in an energy-saving state; receiving first downlink control information (DCI) that is sent by the base station and is scrambled by a power saving radio network temporary identity (PS-RNTI); and performing CSI measurement according to the first indication information and/or the first DCI, and reporting a CSI measurement result to the base station. Therefore, by means of the present invention, a base station can obtain a CSI measurement result in a timely manner and perform effective scheduling, such that a terminal executes CSI reporting in an energy-saving state under the instruction of the base station, thereby improving the efficiency of CSI reporting.

Abstract: A method for indicating energy saving information, a base station and a user terminal. In the prior art, there is a technical problem of a poor energy saving effect when using the PDCCH as an energy saving channel to indicate energy saving information of a UE. The method comprises: carrying first energy saving information in target downlink control information (DCI) of a first time unit, the first energy saving information being used for indicating at least one piece of cross-timeslot scheduling information comprised in a first time window, the first time window comprising at least one time unit using the first time unit or a subsequent time unit as the start point, and the cross-timeslot scheduling information comprising at least among first information and second information, the first information being used for indicating and scheduling the DCI as a cross-timeslot scheduling or a present timeslot scheduling, and the second information being used for indicating the minimum value of a cross timeslot scheduling parameter or the minimum value of a cross-timeslot scheduling parameter in a TDRA list; and transmitting the target DCI to a user terminal.

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, wherein 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, wherein the random access response message comprises 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.
