Bandwidth Part Switching Measurement Gap Activation Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional measurement gap (MG) configuration mechanism in wireless communication systems, particularly in 3GPP Rel-15 and Rel-17, faces challenges in timely activation of MG configurations after a bandwidth part (BWP) switch, leading to potential delays in important signaling and data transmission.
Innovation Solution
A solution that involves a first device receiving a message to switch to a new BWP, triggering the activation of a measurement gap configuration. The device may delay applying at least one measurement gap, and a second device can enable transmission with the first device during at least one measurement gap, ensuring predictable delays and timely activation of the new MG configuration.

Engineering Contradiction Analysis
1Speed
If the measurement gap configuration is activated immediately after BWP switch message reception, then the measurement gap activation speed is improved, but the scheduling of important signaling and data may be disrupted
Solution Approach 1:
The network device determines in advance whether to delay the measurement gap based on the timing relationship between the BWP switch message and the scheduled signaling/data. By performing this determination before the measurement gap activation, the system can prevent disruptions to important communications while still enabling relatively fast activation of the measurement gap.
2Reliability
If the measurement gap is delayed to avoid disrupting signaling and data scheduling, then the scheduling reliability is improved, but the measurement gap activation speed deteriorates
Solution Approach 1:
The system dynamically adjusts the measurement gap activation timing based on real-time scheduling information. The network device determines whether to delay the measurement gap by evaluating the timing relationship with scheduled signaling and data, making the activation time flexible rather than fixed, thus balancing both speed and reliability requirements.
3Measurement precision
If the terminal device suspends communication with serving network device during measurement gaps, then the measurement precision on target carrier is improved, but the communication continuity deteriorates
Solution Approach 1:
The network device performs preliminary determination of whether to delay the measurement gap based on scheduled signaling and data timing. This advance planning ensures that measurement gaps are only activated when they will not conflict with important communications, thereby maintaining communication continuity while still enabling precise measurements when appropriate.

AI summary
Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method implemented at a first device comprises receiving, from a second device, a message for bandwidth part switching for the first device, the message triggering the first device to activate a measurement gap configuration, the measurement gap configuration indicating one or more measurement gaps. The method further comprises delaying to apply at least one measurement gap of the one or more measurement gaps. In this way, the delay of the bandwidth part switching procedure is controllable and predictable for both the first and the second device, and further the required necessary interaction after the bandwidth part switching is ensured thereby, while the new measurement gap configuration may be activated as soon as possible.
