    Abstract: A wireless communication method includes: determining a radio resource for wireless communication, where the radio resource at least includes a first resource set and a second resource set having different attributes; determine, according to content and/or a type of a message carried in a signal to be sent, a resource set used for sending the signal to be sent; and selecting a resource from the determined resource set to send the signal to be sent. This method ensures the delay requirement and the high reliability of specific signal transmission; and reduces the probability of signal collision and improves the reliability of signal transmission.

    Abstract: A method and system for indicating a transmission parameter are provided in the present invention. The method includes: when multi-user multi-input multi-output (MIMO) data are transmitted, using a newly-added indication signaling in a downlink control information format to indicate different joint encoded parameters when numbers of enabled transport blocks are different. Through adding new indication signaling in the present invention, different joint encoded parameters are indicated during the multi-user MIMO data transmission and the MIMO multi-user transmission based on the demodulation reference signal is supported.
