AI Technical Summary

Technical Problem

In the multi-cell DCI scheduling scenario, it is difficult for the UE to effectively monitor and report BD/CCE restrictions for multiple cells, resulting in inefficient allocation of communication resources.

Method used

By implementing the processor circuit in the UE, the following operations are performed: identify the scheduling cell and the cells that can be scheduled by the multi-cell DCI of the scheduling cell in the multiple cells; determine the scaling factor; determine the BD/CCE limits for the multiple cells based on one or more SCS and scaling factors; and monitor control information based on these limitations.

Benefits of technology

The UE is realized to effectively report its ability to be related to multi-cell DCI scheduling and determine the maximum number of BD/CCEs for multi-cell DCI scheduling, thereby improving the allocation efficiency and flexibility of communication resources.

Abstract

A processor and a user equipment (UE) are provided. The processor includes circuitry to execute instructions to cause the UE to perform operations. The operations include identifying, among a plurality of cells for communication with a base station, a scheduling cell and one or more cells that can be scheduled by a same multi-cell downlink control information (DCI) in the scheduling cell, wherein the plurality of cells correspond to one or more subcarrier intervals (SCSs); determining a scaling factor; determining a blind decoding or control channel element (BD / CCE) limit for one or more of the plurality of cells based at least on the one or more SCSs and the scaling factor; and monitoring control information based on the determined limit.
