Abstract

monitoramento de enlace de rádio para comunicações em enlace secundário. trata-se de métodos, sistemas e dispositivos para comunicações sem fio. um equipamento de usuário, ue, se comunica com um ou mais outros ues por um enlace de comunicações em enlace secundário, e realiza um monitoramento de enlace de rádio, rlm, do enlace secundário. um primeiro ue transmite (1005), a um segundo ue, uma primeira mensagem em um primeiro intervalo de tempo de transmissão, tti, através de um enlace de comunicação em enlace secundário. o primeiro ue monitora (1010) o enlace de comunicações em enlace secundário durante um segundo tti subsequente ao primeiro tti para uma mensagem de retroinformações a partir do segundo ue em resposta à primeira mensagem transmitida pelo primeiro ue. o monitoramento faz parte de um procedimento de rlm para o enlace de comunicações em enlace secundário. o primeiro ue incrementa (1015) um contador com base em uma recepção malsucedida da mensagem de retroinformações no segundo tti.
