AI Technical Summary

⚠Technical Problem

Existing wireless communication systems face challenges in efficiently conveying system information (SI) for virtual cells (vCells), as conventional signaling techniques are unable to concurrently indicate shared and unique parameters across multiple serving cells, leading to increased latency and reduced bandwidth in vCell operations.

⚗Method used

The proposed solution involves transmitting SI for vCells that includes a first IE specific to each serving cell and a second IE common across multiple cells, enabling UEs to communicate effectively with a vCell by reducing latency and improving coordination through a single random access procedure.

🎯Benefits of technology

This approach enhances bandwidth and reduces latency by allowing UEs to communicate via vCells efficiently, leveraging shared and unique parameters within the vCell framework.

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communication with a virtual cell (vCell), which may include a set of serving cells that are grouped together to facilitate wireless communication. To implement communications with such vCells, the UE may receive control signaling that indicates one or more resources for reception of system information (SI) that is associated with the vCell. According to the control signaling, the UE may receive the SI via the one or more resources. The SI may include a first information element (IE) associated with a first parameter that is specific to at least one serving cell of the set of serving cells of the vCell, and a second IE associated with a second parameter that is common across two or more serving cells of the set of serving cells of the vCell.
