Abstract: Disclosed is a method and system for enabling user equipment devices (UEs) to apply less attenuation than may be specified more generally for UEs served by a base station of a wireless service provider. The base station may operate on a carrier band, serving UEs that are subscribers of the wireless service provider as well as UEs roaming in the base station's coverage area from another service provider. To avoid uplink transmission power leakage across the edges of the carrier band, the base station may broadcast a message to all the UEs notifying them to attenuate their respective transmission levels. In response, a UE may determine whether or not it is roaming to a wireless communication network of a different service provider. If the UE determines that it is not roaming, it may then attenuate its uplink transmission power by less than an amount indicated by the message.
