Abstract
Se describe técnicas para enviar mensajes para acceso de sistemas. En un aspecto, un equipo de usuario (UE) envía un primer mensaje con información de margen de reserva de potencia y/o de tamaño de memoria intermedia para el acceso de sistema. Un Nodo B determina por lo menos un parámetro (por ejemplo, una concesión de recursos, información de control de potencia, etc.), basándose en el margen de reserva de potencia y/o la información de tamaño de memoria intermedia. El Nodo B envía un segundo mensaje con el o los parámetros. El UE envía un tercer mensaje basándose en el o los parámetros, por ejemplo, con recursos de enlace ascendente indicados por la concesión de recursos, con potencia de transmisión determinada basa en la información de control de potencia, etc. En otro aspecto, el UE indica un reporte de ambiente de radio en el tercer mensaje. El reporte puede utilizarse para seleccionar una celda y/o una frecuencia para el UE. En aún otro aspecto, el segundo mensaje incluye información de control de potencia, y el UE envía el tercer mensaje basándose en la información de control de potencia.
