Abstract

controle de potência de sidelink. métodos, sistemas e dispositivos para comunicação não cabeada são descritos. geralmente, as técnicas descritas proporcionam executar e reportar eficientemente as medições de potência recebida de sinal de referência (rsrp). em particular, as técnicas descritas neste documento podem permitir que um equipamento do usuário (ue) identifique eficientemente sinais de referência nos quais executar medições rsrp (por exemplo, baseado na sinalização a partir de uma estação base), identificar quando reportar medições rsrp (por exemplo, aperiodicamente, periodicamente ou semi-persistentemente) e identificar um canal no qual reportar medições rsrp (por exemplo, um canal de sidelink ou um canal de uplink). adicionalmente, as técnicas descritas neste documento também podem permitir que um ue identifique eficientemente parâmetros de malha aberta que devem ser utilizados para determinar uma potência de transmissão apropriada para transmitir para outro ue através de um sidelink.
