Abstract

Se divulgan un método y un aparato para realizar una transferencia en una red de acceso radioeléctrico terrestre universal evolucionada (E-UTRAN). Una unidad inalámbrica de transmision/recepcion (WTRU) envía un informe de medicion a un Nodo B evolucionado (eNB) de origen y recibe una orden de transferencia desde el eNB de origen. La WTRU inicia la recepcion y el procesamiento de un canal de difusion primario (P-BCH) en la celda meta después de recibir la orden de transferencia. La WTRU luego envía un preámbulo de acceso al azar al eNB meta, recibe una respuesta de acceso al azar desde el eNB meta y envía un mensaje de transferencia completo al eNB meta. La recepcion y el procesamiento del P-BCH pueden ser iniciados inmediatamente después de recibir la orden de transferencia o después de enviar el mensaje de transferencia completo. La WTRU puede aplicar una configuracion por defecto o una configuracion de la celda de origen en la celda meta hasta adquirir un SFN de la celda meta y/o informacion del P-BCH.
