摘要

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.

說明書

Aspects of the method of FIG. 9 may be implemented by a wireless device and a cellular base station, such as a UE 106 and a BS 102 illustrated in and described with respect to various of the Figures herein, or more generally in conjunction with any of the computer circuitry, systems, devices, elements, or components shown in the above Figures, among others, as desired. For example, a processor (and/or other hardware) of such a device may be configured to cause the device to perform any combination of the illustrated method elements and/or other method elements. Note that while at least some elements of the method of FIG. 9 are described in a manner relating to the use of communication techniques and/or features associated with LTE, LTE-A, and/or 3GPP specification documents, such description is not intended to be limiting to the disclosure, and aspects of the method of FIG. 9 may be used in any suitable wireless communication system, as desired. In various embodiments, some of the elements of the methods shown may be performed concurrently, in a different order than shown, may be substituted for by other method elements, or may be omitted. Additional method elements may also be performed as desired.
