The entire content of the above identified application is incorporated herein by reference. Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure.

FIELD OF THE DISCLOSURE The present disclosure relates to a method and a system, and more particularly to a communication method and a communication system. BACKGROUND OF THE DISCLOSURE According to the existing specifications of the 3rd generation partnership project (3GPP), due to mobility issues, the user equipment (UE) must perform channel quality measurements, such as reference signal received power (RSRP) and reference signal received quality (RSRQ), during configured periodic measurement gaps (MGs). During these measurement periods, transmission or reception is prohibited. Additionally, under the current 3GPP specifications, the base station pre-allocates periodic uplink and downlink transmission resources to the UE to reduce frequent signal exchanges. When pre-configured uplink and downlink transmission resources, such as semi-persistent scheduling (SPS) or configured grant (CG), conflict with MGs, priority is given to the channel quality measurements. However, in the face of the rapid development of immersive experience technologies such as extended Reality (XR), augmented reality (AR), virtual reality (VR), and cloud gaming, it is necessary to establish new communication mechanisms to meet users' demands for high-definition and low-latency. Wireless networks must ensure that bandwidth and communication resources, such as the PDU Set Delay Budget (PSDB), meet these requirements.
