Abstract
This disclosure relates to providing a reservation signal for cellular communication in unlicensed spectrum. A cellular base station may perform a listen-before-talk procedure on an unlicensed frequency channel. The cellular base station may transmit a reservation signal on the unlicensed frequency channel after successfully performing the listen-before-talk procedure. The cellular base station may perform carrier sensing on the unlicensed frequency channel at least once during the duration of the reservation signal. The cellular base station may perform cellular communication on the unlicensed frequency channel after ceasing transmitting the reservation signal.
