Solution Overview
Problem
In wireless communication systems, identifying a minimum gap between control channel transmissions and reference signal transmissions across component carriers with different numerologies is challenging, leading to inefficient buffering and resource management, especially when performing beam switching.
Innovation Solution
The techniques involve identifying a minimum gap based on the location of the control channel transmission within a slot or the numerology difference between component carriers, allowing for efficient synchronization and measurement reporting without substantial buffering, and incorporating beam switching times for optimal resource allocation.

1Quantity of substance
If offsets between control channel transmission and reference signal transmission are provided to reduce buffering, then buffering requirements are reduced, but efficient identification and management of offsets becomes more complex
Solution Approach 1:
The patent changes the parameter representation by defining offsets in terms of OFDM symbol locations rather than absolute time offsets. This allows the offset to be dynamically adjusted based on the control channel position within a slot, transforming a fixed parameter into a flexible one that adapts to different transmission scenarios.
Solution Approach 2:
The patent segments the offset calculation into two parts: a base offset value and an additional offset derived from the control channel's OFDM symbol location. This segmentation allows independent optimization of each component and simplifies the overall management by breaking down a complex timing relationship into manageable parts.
2Productivity
If beam switching is performed between component carriers, then resource allocation is optimized, but additional time for beam switch is required
Solution Approach 1:
The patent incorporates beam switching time into the offset calculation in advance. By determining the minimum gap between control channel and reference signal transmissions to account for beam switching duration, the system performs the beam switch preparation beforehand, ensuring that the reference signal transmission is ready when needed without causing delays.
3Adaptability or versatility
If component carriers with different numerologies are used, then system flexibility is improved, but identifying minimum gap between transmissions becomes more difficult
Solution Approach 1:
The patent resolves the difficulty by changing the dimension in which the gap is measured. Instead of using absolute time units that vary with numerology, the patent expresses the minimum gap in terms of OFDM symbol locations, which provides a numerology-independent reference frame. This dimensional change allows consistent gap identification across different numerologies.

AI summary
Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.
