Clear-to-send signaling to limit WiFi interference in unlicensed spectrum

摘要

Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.

主权项

1. A method of wireless communications, comprising:
transmitting a clear-to-send (CTS) signal from a mobile device over a channel in an unlicensed radio frequency spectrum band, the transmitting of the CTS signal being based at least in part on resource schedule information transmitted in the unlicensed frequency spectrum band, the CTS signal being transmitted after transmitting an information portion comprising a shortened frame; transmitting, after transmitting the CTS signal, a full frame comprising information different from the information portion; and receiving data over the channel during a period of time set by the CTS signal.
