Unanswered Questions

How does the dynamic MCS table switching impact power consumption in the UE?

The abstract does not mention the potential impact of dynamic MCS table switching on power consumption in the UE. This could be an important consideration for practical implementation and user experience.

Are there any limitations to the number of MCS tables that can be supported simultaneously?

The abstract does not specify if there are any limitations to the number of MCS tables that can be activated or supported simultaneously. Understanding these limitations could provide insights into the scalability and performance of the proposed technology.


Original Abstract Submitted

MAC-CE based dynamic MCS tables switching is introduced to support addition of higher modulation orders and new constellation types. First, a UE receives a RRC configuration indicating a plurality of MCS tables. Next, the UE receives a MAC CE activating a MCS table among the plurality of MCS tables. Doing so allows MCS tables to be dynamically switched via a MAC-CE based activation/reactivation adaptive to current signal to noise (SNR)/spectral efficiency (SPEF) experienced in a downlink and uplink. Finally, the UE communicates data with a base station using a MCS in the activated MCS table.
