JP-2026514414-A - Resource determination method, apparatus, communication device, and storage medium

Abstract

This disclosure relates to the telecommunications technology, and more specifically to resource determination methods, apparatus, communication apparatus, and storage media. The resource determination method includes the step of receiving a channel state information reference signal, wherein the number of configurable frequency domain resource units of the channel state information reference signal resource is greater than or equal to the minimum of a first number and a second number, where the second number is the number of frequency domain resource units occupied by a first frequency domain resource capable of receiving downlink transmissions. According to this disclosure, a terminal can receive a CSI-RS and determine that the number of configurable frequency domain resource units of the CSI-RS is greater than or equal to the minimum of the first number and the second number. The number of frequency domain resource units of the CSI-RS resource configured for the terminal by the network device will not be less than the minimum of the first number and the second number. This is advantageous in ensuring that the network device and the terminal have a consistent understanding of the CSI-RS resource, and that the quality of subsequent communication between the network device and the terminal is ensured.
