Abstract

The present application provides a downlink time domain resource scheduling method and network equipment, wherein the method includes: determining the downlink time domain resources allocated to the terminal device; according to the time domain scheduling mode configured for the terminal device and the downlink time domain resource The target time-domain resource indication is determined in the resource index table. The target time-domain resource indication is used to indicate the first start symbol of the downlink time-domain resource in the time slot and the number of first symbols corresponding to the downlink time-domain resource. The first start symbol is associated For the start symbols in the start symbol set of the time-domain scheduling mode and the time slot acquisition mode, the first number of symbols is the symbols in the symbol number set associated with the time-domain scheduling mode, the time slot acquisition mode and the start symbol Quantity; sending the DCI signaling carrying the target time domain resource indication to the terminal device. By adopting the solution of the present application, the combination of the start symbol and the number of symbols of downlink time domain resources can be reduced, thereby reducing DCI signaling overhead.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a downlink time-domain resource scheduling method and network equipment. Background technique [0002] In a wireless communication system, a terminal device may perform downlink transmission using time-frequency resources allocated to the terminal device by a network device, where the time-frequency resource includes time-domain resources and frequency-domain resources. Before the terminal device uses the time-frequency resource allocated by the network device for downlink transmission, the network device needs to schedule and allocate the time-frequency resource, and the network device allocates time-domain resources and frequency-domain resources for the terminal device through time-domain scheduling and frequency-domain scheduling respectively . [0003] In New Radio (NR) technology, there are two time-domain scheduling methods, one is based on time slot ...
