Abstract

The invention discloses a time domain determination method and a communication device, which are used for solving the technical problem that in the prior art, a DCI (Downlink Control Information) indication mode for a time domain allocation mechanism in an NR (New RAT(Radio Access Technology)) can increase UE blind test complexity and air interface cost. The method comprises the steps of: receiving DCI; acquiring time slot allocation information in the DCI, wherein the time slot allocation information is used for indicating N time slots allocated to a data channel, and N is an integer greaterthan 0; acquiring symbol allocation information in the DCI, wherein the symbol allocation information is used for indicating symbol allocation in each time slot in the N time slots or used for indicating an initial symbol in a first time slot and an end symbol in an Nth time slot in the N time slots; and based on the time slot allocation information and the symbol allocation information, determining time domain resources allocated to the data channel.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for determining time-domain resources and a communication device. Background technique [0002] New radio access technology (New RAT (radio access technology), NR) supports flexible channel time domain resource allocation mechanisms, including single slot resource allocation, slot aggregate resource allocation, and slot and symbol aggregate resource allocation. Wherein, in single-slot resource allocation, the network side allocates a time slot for the data channel, and the network side may further indicate symbol allocation in the time slot. For time slot aggregation resource allocation, the network side allocates multiple time slots for the data channel, and similarly, the network side may further indicate symbol allocation in the multiple time slots. Time slot and symbol aggregation resource allocation, the network side allocates one or more time slots a...
