AI Technical Summary

Technical Problem

When existing wireless communication systems process multiple packets, it is difficult to effectively manage the threshold occupancy of packet buffers, resulting in possible undesirable refresh operations that affect performance and user experience.

Method used

Through the processor of the user equipment, packets are received using dual connection technology (such as dual cell connection) and packets are added in the packet buffer. When the threshold occupancy of the packet buffer is detected, the degradation of the second wireless communication link is simulated to delay the refresh operation, providing additional time to receive the missing packets.

Benefits of technology

Effectively manage the threshold usage of packet buffers, avoid undesired refresh operations, improve system performance and user experience, and reduce waste of network capacity.

Abstract

In general, various aspects of the present disclosure relate to wireless communications. In some aspects, a method may include simulating degradation of at least one of a first wireless communication link with a network or a second wireless communication link with a network based on detecting that a first set of one or more packets received via a first wireless communication link with a network and added to a packet buffer and a second set of one or more packets received via a second wireless communication link with a network and added to the packet buffer satisfy a threshold occupancy of the packet buffer. Numerous other aspects are also provided.
