Abstract  Abstract

Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. In one embodiment a method includes synchronizing in an aligned clear channel assessment (CCA) period comprising a plurality of Orthogonal Frequency-Division Multiplexing (OFDM) symbol positions CCA slots to determine availability of a shared spectrum for transmissions in a next transmission interval wherein a first CCA slot of the CCA slots is aligned with a first OFDM symbol position of the plurality of OFDM symbol positions and a second CCA slot of the CCA slots is aligned with a second OFDM symbol position of the OFDM symbol positions.
