Abstract
resumo mecanismo para monitoramento de enlace de rádio e tratamento de falha de enlace de rádio em redes de célula pequena um método de monitoramento de enlace de rádio (rlm) e tratamento de falha de enlace de rádio (rlf) através de uma rede de célula pequena é proposto. em uma rede sem fio, um equipamento de usuário (ue) estabelece uma conexão de controle de recursos de rádio (rrc) com uma estação base (enb), que é âncora de ue. o ue aplica agregação de portadora para múltiplas portadoras de componente (ccs) configuradas como múltiplas células servindo. as células servindo agregadas são servidas pelo enb de âncora e outro enb de desvio (s). o ue realiza rlm / rlf sobre pcell e scell pertencentes a grupos de células correspondentes. quando rlf acontece em uma célula servindo, o ue e o enb aplicam determinadas ações sobre a célula servindo ou todas as células servindo no grupo. procedimentos de rlf em enb de âncora e em enb de desvio são propostos. tanto comportamento de lado de ue e lado de rede são incluídos.
