Abstract
A data transmission method, comprises: receiving a plurality of pieces of control information issued by a base station via a plurality of beams, each piece of control information comprising resource information, the resource information indicating one or more transmission units configured by the base station for a terminal; using the plurality of beams to perform data transmission on the plurality of transmission units indicated by the plurality of pieces of control information.
Claims8
A data transmission method, the method comprising:
- receiving, by a terminal, a plurality of pieces of control information transmitted by a base station via a plurality of beams, each piece of control information being information for resource scheduling and comprising resource information, the resource information indicating one or more transmission units configured by the base station for the terminal to send data or receive data, each transmission unit being a slot, a symbol, a sub-frame, a radio frame, or other types of time domain units in time domain, and each transmission unit being a frequency domain resource block, a bandwidth part, or other types of frequency domain units in frequency domain;
- acquiring, by the terminal, a first plurality of transmission units indicated by a first piece of control information, the first piece of control information being any one of the plurality of pieces of control information;
- obtaining, by the terminal, a plurality of beams corresponding to the first plurality of transmission units by querying a pre-stored corresponding relation between a transmission unit and a beam, each beam corresponding to at least one transmission unit and
- performing, by the terminal, data transmission, via a first beam, on at least one transmission unit corresponding to the first beam among the first plurality of transmission units indicated by the first piece of control information, the first beam being any one of the plurality of beams corresponding to the first plurality of transmission units.
