Problems solved by technology

For the CORESET used for PDCCH transmission, each CORESET MAC signaling will only correspondingly activate one of the multiple TCI states configured by its RRC signaling, then when the terminal receives the PDCCH sent on the CORESET, it will Using this TCI state activated by the MAC to determine the receiving beam, the reliability is relatively low

Abstract

The disclosure relates to a data transmission method and a data transmission device. The data transmission method is applied to network equipment and comprises the steps of configuring a plurality ofdifferent frequency domain resources and configuring the same time domain resources for the plurality of different frequency domain resources; and sending the same downlink control signaling by the same time domain resource in a plurality of wave beam directions through the plurality of different frequency domain resources. By the method and the device, the same downlink control signaling can be repeatedly sent, and the communication reliability can be improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method and a data transmission device. Background technique [0002] In a new wireless technology (New Radio, NR), in order to ensure coverage and resist path loss, it is generally necessary to perform data transmission based on a beam (beam). [0003] During beam-based data transmission, a network device (such as a base station) indicates a Transmission Configuration Indication (TCI) status or spatial relation information (spatial relation info) through signaling, and then indicates a receiving beam or a transmitting beam of a terminal. Wherein, each TCI state or each spatial relationship information corresponds to a reference signal (Reference Signal, RS) identifier, and the RS can be a non-zero power channel state information reference signal (Channel State Information Reference Signal, CSI-RS) or It is a synchronization signal block...
