EXTENDING A TIME GAP RANGE FOR NON-TERRESTRIAL NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17598239 titled 'EXTENDING A TIME GAP RANGE FOR NON-TERRESTRIAL NETWORKS

Simplified Explanation

The patent application describes a base station that determines the timing and slot for uplink reception in a non-terrestrial network link between a base station and a user equipment. Here are the key points:

• The base station determines the timing advance by analyzing the reception of a random access preamble.
• Based on the timing advance, the base station calculates an uplink offset.
• Using the uplink offset, the base station identifies a candidate slot for uplink reception.
• The base station checks if the candidate slot is available for uplink reception.
• If the candidate slot is available, the base station uses it for uplink reception.
• If the candidate slot is not available, the base station selects the next available slot for uplink reception.

Potential applications of this technology:

• Non-terrestrial network communication systems
• Satellite communication systems
• Wireless communication networks

Problems solved by this technology:

• Efficient allocation of uplink slots in non-terrestrial network links
• Optimizing timing and offset calculations for uplink reception
• Avoiding interference and collisions in uplink transmissions

Benefits of this technology:

• Improved reliability and performance of non-terrestrial network links
• Enhanced efficiency in uplink slot allocation
• Minimized interference and collisions in uplink transmissions

Original Abstract Submitted

A base station that determines a slot for uplink reception for a non-terrestrial network link between a base station and a user equipment is described. In exemplary embodiments, the base station determines a timing advance based on at least a random access preamble reception and determines an uplink offset based on the timing advance. The base station may further determine a candidate slot for an uplink reception based on at least the offset. In addition, the base station may determine if the candidate slot is available for the uplink reception. The base station may use the candidate slot for the uplink reception when the candidate uplink slot is available and may use the next available slot for the uplink reception when the candidate uplink slot is not available.
