Abstract

a divulgação prevê medições de plano de controle em um dispositivo sem fio. o dispositivo sem fio pode executar, em sinais recebidos ao longo de um espectro não licenciado em vários subquadros, medições de gerenciamento de recursos de rádio (rrm) de uma célula. o dispositivo sem fio pode identificar um ou ambos de um primeiro subconjunto das medições rrm associadas com um primeiro subconjunto dos subquadros, incluindo transmissões oportunistas e de um segundo subconjunto das medições rrm associadas com um segundo subconjunto dos subquadros, incluindo transmissões garantidas. o dispositivo sem fio pode determinar um ou mais valores de medição rrm baseado em um ou ambos do primeiro subconjunto das medições rrm e do segundo subconjunto das medições rrm. o dispositivo sem fio pode igualmente realizar medições de gerenciamento de ligação de rádio (rlm) e determinar valores de medição rlm com base nos primeiro e segundo subconjuntos. o dispositivo sem fio também pode usar os temporizadores para as transmissões de ligação ascendente para detectar falhas de ligação de rádio.
