Abstract

TRANSMISSÕES DE BLOCO DE SINAL DE SINCRONIZAÇÃO DE SIDELINK EM UM ESPECTRO COMPARTILHADO. Métodos, sistemas e dispositivos para comunicações sem fio são descritos. Geralmente, as técnicas descritas fornecem recursos de identificação eficientes para transmitir um ou mais blocos de sinal de sincronização de sidelink (S-SSBs) no espectro compartilhado ou varredura de feixe eficiente de múltiplos S-SSBs no espectro compartilhado. Sob um aspecto, um equipamento de usuário (UE) pode transmitir um S-SSB em uma parte de largura de banda (BWP) de sidelink no espectro compartilhado de modo que uma borda inferior do S-SSB esteja alinhada com ou deslocada de uma borda inferior da BWP de sidelink. Sob outro aspecto, um UE pode efetuar varredura de feixe de S-SSBs em uma ou mais rajadas de S-SSB em um período de S-SSB para aumentar as chances de que outro UE possa receber os S-SSBs. Sob ainda outro aspecto, recursos alocados para transmissões de S-SSB podem facilitar transmissões de S-SSB flexíveis enquanto minimizam as lacunas para evitar que outros UEs determinem incorretamente que uma BWP de sidelink em um espectro compartilhado está liberada para transmissão.
