Abstract: The present application is for use in reducing the overhead of transmitting beam information between a transmitting end and a receiving end. Disclosed are a method for indicating and determining beam information, a device, and a communication system. The method provided in the present application for indicating beam information comprises: a transmitting end determines a first transmission beam that needs to be used for transmission with a receiving end; the transmitting end determines, on the basis of first mapping relations between beam pair (BPL) identifiers and transmission beams, a first BPL identifier corresponding to the first transmission beam, where the receiving end is provided with second mapping relations between the BPL identifiers and reception beams; the transmitting end transmits the first BPL identifier to the receiving end; and the transmitting end uses the first transmission beam to transmit a signal to the receiving end.

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: The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.
