Provided are a device and method for a wireless communication system, and a computer readable storage medium. The device comprises a processing circuit. The processing circuit is configured to: acquire the current three-dimensional spatial location of a user equipment, and determine a resource for the user equipment according to information showing a mapping relationship at least between three-dimensional spatial regions and resources. According to an aspect of the embodiment of the present disclosure, time delay can be decreased and transmission performance can be optimized by pre-establishing a mapping relationship between three-dimensional spatial regions and resources and assigning to the user equipment an uplink/downlink time-frequency resource on the basis of the mapping relationship.
