Abstract

The present invention discloses a scheduling information transmission method and device. According to the scheduling information transmission method and device, a network device determines the quantity of the scheduling information of a terminal; scheduling frequency resources are adopted to send the scheduling information according to the determined quantity of the scheduling information; the scheduling information is located on a physical downlink control channel and is used to indicate the data channel resources of scheduled frequency resources on the scheduling frequency resources; the scheduling information is DCI or an information domain in the DCI; the quantity of the scheduling information is smaller than or equal to the maximum value of a scheduling information quantity, or is determined according to the time domain unit length of the scheduled frequency resources and the time domain unit length of the scheduling frequency resources, or determined according to the subcarrier spacing of the scheduled frequency resources, the subcarrier spacing of the scheduling frequency resource and a first preset value, or is determined according to the time unit length of the scheduled frequency resources, the time unit length of the scheduling frequency resources and the first preset value, wherein the first preset value is used to determine the numbers of the schedulable maximum time domain units of the scheduling information. With the scheduling information transmission method and device of the invention adopted, the complexity of frequency resource scheduling can be decreased.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a scheduling information transmission method and device. Background technique [0002] The continuous growth of smart terminal users, user business volume and data throughput continue to increase, which puts forward higher requirements for communication bandwidth and speed. For this reason, a carrier aggregation (Carrier Aggregation, CA) technology is introduced. Multiple continuous or discontinuous component carriers can be aggregated and used through carrier aggregation. In addition, the 5th Generation mobile communication technology New Radio (5G NR) system also defines other frequency resources, such as Partial bandwidth (Bandwidth Part, BP) solves the demand for large bandwidth in mobile communication, and improves the utilization rate of scattered spectrum in the wireless frequency band. The carrier aggregation technology of the Long Term Evol...
