Abstract

Un método para seleccionar uno o más haces de TX a identificar en un reporte de haz. El método incluye un UE que obtiene i) un primer valor de interferencia, Ia, asociado con una primera disposición de antenas y ii) un segundo valor de interferencia, Ib, asociado con una segunda disposición de antenas. El método también incluye al UE que obtiene i) un valor de potencia, P1a, asociado con la primera disposición de antenas y con un primer haz de TRP TX y ii) un valor de potencia, P1b, asociado con la segunda disposición de antenas y con el primer haz de TRP TX. El método incluye además al UE que determina un primer valor de potencia final, Pn1, con base en Ia y Ib y con base en al menos uno de P1a y P1b. El método también incluye al UE que usa Pn1 para determinar si se incluye o no en el reporte de haz un identificador para identificar el primer haz de TRP TX.
