Abstract
IDENTIFICAÇÃO DE ZONA (ID) PARA COMUNICAÇÕES EM SIDELINK SEM FIO. Um equipamento de usuário (UE) de sidelink recebe um sinal de despertar de grupo (WUS) de uma estação base e decodifica o WUS de grupo com base na informação de identificação (ID) de zona do UE de sidelink. Uma estação base transmite um sinal de despertar para um grupo de equipamentos de usuário (UEs) de sidelink e transmite a informação de ID de zona para o grupo. Um parâmetro de sinal de despertar de grupo é uma função da informação de ID de zona. Uma estação base gera uma sequência de sinal de referência de demodulação (DMRS), seleciona uma porta para um DMRS, e/ou criptografa um canal de controle ou um canal de dados com base em uma ID de zona de um UE de sidelink. Um UE de sidelink compara uma ID de zona do UE de sidelink com uma ID de zona de um UE vizinho e inicia uma transferência condicional para outra célula quando a ID de zona do UE de sidelink difere da ID de zona do UE vizinho.
