Abstract

See full text

Wireless communications systems and methods related to sharing a frequency-division duplexing (FDD) spectrum among multiple network operating entities. In one embodiment, a first wireless communication device communicates, with a second wireless communication device in a downlink (DL) frequency band, a reservation signal in a first channel sensing time slot of a frame to reserve a transmission time slot in the frame. The first wireless communication device communicates, in an uplink (UL) frequency band, an UL control signal in the first channel sensing time slot. The UL frequency band and the DL frequency band are shared by a plurality of network operating entities for frequency-division duplexing (FDD) communications. In another embodiment, a first wireless communication device communicates, in a first frequency band of a FDD network shared by a plurality of network operating entities, a reservation signal to reserve the first frequency band for time-division duplexing (TDD) communications.
