Problems solved by technology
[0004] However, in the future, MIMO (Multiple-Input Multiple-Output) needs to support data transmission based on multiple TRPs or multiple antenna panels (panel), that is, the base station needs to use multiple transmit beam directions for data transmission, and the corresponding , the user equipment needs to use multiple receiving beams for data reception, then the signaling used to indicate the direction of one receiving beam in the related art will no longer be applicable to future evolution. In the case of , how to design new signaling to enable data transmission between the base station and user equipment through multi-beams has become a problem to be solved urgently by those skilled in the art

The invention relates to a data transmission method, a base station, user equipment and a storage medium, and belongs to the technical field of communication. The method comprises the following steps:the base station generates signaling for indicating at least two receiving beams of the user equipment, wherein the signaling comprises the TCI states of a plurality of TBs, the plurality of TBs aresent by at least two panels, the at least two panels are different panels from the same TRP or panels from different TRPs, and the plurality of TBs correspond to at least two receiving beams of the user equipment; and the base station sends the signaling to the user equipment, so that the user equipment determines a receiving beam for receiving each TB in the plurality of TBs according to the signaling, and receives each TB by using the determined receiving beam. According to the invention, new signaling is designed, so that when the base station uses a plurality of transmitting beam directions to transmit data, the user equipment can use a plurality of receiving beams to receive data, and the base station and the user equipment can transmit data through a plurality of beams.
Description
technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a data transmission method, a base station, user equipment, and a storage medium. Background technique [0002] In NR (New Radio, new wireless technology), when the communication frequency band is located in FR (Frequency Range, frequency range) 2, due to the large path loss of high-frequency communication, in order to ensure coverage and resist path loss, it is usually necessary to use beam-based (beam) for data transmission. Among them, FR2 refers to a high-frequency band with a frequency greater than 6 GHz. For example, for the beam-based receiving process, the base station indicates the TCI (Transmission Configuration Indication, transmission configuration indication) status of type D through signaling, so as to inform the user equipment of the receiving beam to be used when receiving. Wherein, each TCI state corresponds to an RS (Reference Signal, refer...
