Abstract

The invention provides a transmission configuration method based on pre-scheduling, a transmission parameter determination method and equipment and belongs to the technical field of wireless communication. The configuration method comprises the step: configuration information is sent to the terminal, wherein the configuration information at least comprises information of frequency hopping resources, so that the terminal can determine a transmission parameter corresponding to each frequency hopping resource according to the configuration information; the transmission parameter comprises at least one of MA signal, MA codeword and DMRS port. The invention provides a pre-scheduling-based transmission parameter determination mode adopting a frequency hopping mode.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a pre-scheduling-based transmission configuration method, transmission parameter determination method and equipment. Background technique [0002] A transmission method in the 5G NR (5th-Generation New Radio, fifth-generation mobile communication technology-new air interface) standard is based on pre-scheduled transmission (transmission with configured grant), and the base station uses RRC (Radio Resource Control, radio resource Control) signaling pre-configures relevant parameters for transmission. Users use pre-configured transmission parameters on pre-scheduled time-frequency resources to transmit data directly or through L1 (physical layer) signal triggers, without sending SR (Scheduling Request, scheduling request) and waiting for dynamic scheduling signaling, reducing Data transmission delay and control signaling overhead required for dynamic schedul...
