Maximum power reduction based on traffic priority
The disclosed technology provides a system and method for allocating resource blocks to a mobile device based on a traffic priority of wireless resources between the network and the mobile device. Traffic priority can be determined based on quality of service (QOS) identifiers or network slice identifiers. The highest priority users are allocated inner resource blocks with the lowest allowed maximum power reduction (MPR), the lowest priority users are allocated edge resource blocks with the highest allowed MPR, and the intermediate priority users are allocated outer resource blocks.
