Uplink Radio Resource Allocation for GNSS Interference Mitigation

The network node determines the GNSS reception time interval in advance before performing radio resource allocation. By knowing the timing of GNSS reception beforehand, the network node can proactively avoid allocating uplink radio resources that would coincide with this interval, thereby preventing IMD interference before it occurs. This preliminary determination of the protection interval resolves the contradiction by enabling advance planning of resource allocation that protects GNSS reception while maintaining data transmission productivity.

The uplink radio resources are segmented in time by excluding only the specific GNSS reception time interval from resource allocation, while all other time intervals remain available for normal data transmission. This segmentation approach protects GNSS reception quality by creating a dedicated protection window, while minimizing the impact on overall data transmission efficiency since resources outside this interval continue to be allocated normally. The protection interval is calculated based on precise timing information, ensuring minimal resource restriction.

The network node autonomously determines the GNSS reception time interval by obtaining timing information from the user equipment, then independently performs radio resource allocation to avoid this interval. The user equipment simply provides the necessary timing parameters (such as reception start time and duration) without needing to implement complex interference mitigation algorithms. This self-service approach where the network node takes the lead in protecting GNSS reception while the user equipment provides minimal input information resolves the contradiction by achieving effective protection without increasing overall system complexity.
