Abstract

ATUALIZAÇÃO POR AVANÇO TEMPORAL PARA CÉLULAS NÃO SERVIDORAS. A presente invenção se refere, em vários aspectos, à comunicação sem fio em geral. Em alguns aspectos, um equipamento de usuário (UE) pode receber ou determinar informações indicando um avanço temporal para uma célula não servidora do UE, e realizar uma operação de mobilidade entre células com base, pelo menos em parte, no avanço temporal para a célula não servidora do UE. Vários outros aspectos são fornecidos.
