Method and system for synchronizing uplink symbol timing at an eNodeB in cellular networks by compensating for propagation delays using timing advance mechanisms.

Patentradars sammanfattning

This patent addresses downlink-uplink timing synchronization in cellular networks, particularly the challenge of aligning uplink (UL) transmissions from multiple user equipment (UE) at the eNodeB receiver despite varying propagation delays. The invention employs timing advance signaling to compensate for distance-dependent propagation delays, ensuring that UL symbols arrive time-aligned at the eNodeB despite UEs being at different distances, thereby eliminating timing misalignment that would otherwise degrade reception quality.
