Abstract
An information handling system stores multicast broadcast service (MBS) link adaption (LA) configurations. Based on the MBS LA configurations, the system transmits a channel quality indications (CQI) report request. The system receives a CQI report and applies CQI filtering to the received CQI report and a CQI of the information handling system. In response to the CQI filtering being applied, the system provides an LA group filtered CQI report to a radio access network node.

A broadcast system comprising:
- a sidelink information handling system;
- and
- an information handling system configured to communicate with the sidelink information handling system, the information handling system includes:
- a memory to store multicast broadcast service (MBS) link adaption (LA) configurations;
- and
- a processor to communicate with the memory, the processor to:
- receive the MBS LA configurations;
- based on the MBS LA configurations, transmit a channel quality indications (CQI) report request to the sidelink information handling system that is external to the information handling system, wherein the CQI report request is transmitted to the sidelink information handling system that is geolocated via a sidelink, wherein the sidelink information handling system and the information handling system are geolocated when both of the sidelink information handling system and the information handling system receive a MBS payload from a same downlink beam of a plurality of available downlink beams;
- receive a first CQI report from the sidelink information handling system based on a change in COI of the sidelink information handling system being greater than a CQI change threshold;
- apply CQI filtering to the received first CQI report and a second CQI report of the information handling system;
- in response to the CQI filtering being applied, determining whether a coverage level of the same downlink beam is below a threshold coverage level, wherein the coverage level is determined based on a dB level of the same downlink beam;
- in response to the coverage level of the same downlink beam is below a threshold coverage level, provide a LA group filtered CQI report to a radio access network (RAN) node;
- receive a RAN modulation and coding scheme (MCS) level;
- and
- transmit the RAN MCS level to the sidelink information handling system, wherein the RAN MCS level is scrambled with a configured group-common LA identifier to the sidelink information handling system,
- the sidelink information handling system provides the first CQI report in response to a first LA report request from the processor and a determination that the information handling system has a strongest received coverage for transmission of multiple LA report requests from other geolocated information handling systems, wherein the strongest received coverage is based on reference signal received power levels of the first LA report request and the multiple LA report requests, wherein the sidelink information handling system discards the multiple LA report requests from the other geolocated information handling systems.
