AI Technical Summary

Technical Problem

In existing technologies, the scheduling mechanism for measurement gaps relies on the network's preset absolute time, which leads to a lack of coordination between the network and the terminal's discontinuous reception cycle. This causes the terminal to wake up additionally when there is no data transmission because the measurement gap overlaps with the sleep period, increasing power consumption and shortening battery life. This problem is particularly prominent in scenarios with high mobility or fluctuating network load.

Method used

By using terminal capability reporting and network-side collaborative configuration strategies, the alignment of measurement gaps and discontinuous reception cycles is dynamically adjusted to ensure that measurement gaps are executed during the terminal's active period. This includes precise alignment of cycle multiples and start offsets, and alignment is achieved using newly added terminal capability indication parameters and radio resource reconfiguration signaling.

Benefits of technology

It reduces the extra power consumption of the terminal due to wake-up during measurement intervals, extends battery life, ensures measurement performance and network connectivity robustness, adapts to dynamic changes in terminal service status, and makes network configuration easy to implement and deploy.

Abstract

This invention relates to a method for coordinating measurement gaps and discontinuous reception, comprising the following steps: S1, terminal capability reporting and identification; S2, network-side collaborative configuration strategy; S3, dynamic adjustment mechanism. This invention provides a method for coordinating measurement gaps and discontinuous reception, which can save terminal power consumption. By forcibly aligning the measurement gaps to the C-DRX period and prioritizing their placement within the onDuration period, connected-state power consumption is minimized. Measurement performance is guaranteed, ensuring the integrity and availability of the measurement gaps. The terminal will not miss necessary measurements due to power saving, ensuring the performance of critical functions such as handover and carrier aggregation, and maintaining network connectivity robustness. Network efficiency is high, as decisions and configurations are primarily made by the network side, requiring minimal modifications to the terminal and being easy to implement and deploy. The dynamic adjustment strategy allows the collaborative relationship to adapt to dynamic changes in the terminal's service status, maintaining the effectiveness of the strategy.
