Abstract

Various methods for controlling an aggressor user equipment (UE) can use two transmission power control loops to mitigate UE-to-UE adjacent carrier frequency band interference to a geographically proximal victim UE. The aggressor UE can select between different transmission power parameters based on two (or more) power values. The usage of any particular power value depends on the time period of the transmission. For example, if a proximal victim UE is scheduled to receive when the aggressor UE is scheduled to transmit, a lower power value may be selected as instructed by a co-scheduler or determined by the aggressor UE. The aggressor UE can also send dual power headroom reports to its serving base station based on the two power values.
