Abstract: Wireless communications systems and methods related to dynamic time-division duplexing (TDD) and self-contained subframe-based communications in a shared spectrum are provided. A first wireless communication device communicates a control information communication protection request over a shared spectrum. The shared spectrum is shared by a plurality of network operating entities based on priorities. The first wireless communication device is associated with a first network operating entity of the plurality of network operating entities. The first wireless communication device communicates, with a second wireless communication device associated with the first network operating entity, control information in a first link direction during a transmission opportunity (TXOP) in the shared spectrum. The first wireless communication device communicates, with the second wireless communication device, data in a second link direction during the TXOP.

Abstract: Due to the limited dimension of a NB that may be used by multiple users, as well as possible large coverage areas, timing offset estimation may be outside of NCP. The inaccuracy in the timing estimate can be improved by using more than one tone hopping distance for PRACH. An apparatus may then transmit a first and second tone of the PRACH at a first hopping distance from the first tone. The apparatus may then transmit a third tone of the PRACH and a fourth tone of the PRACH at a second hopping distance from the third tone. The second hopping distance may be greater than first hopping distance. The apparatus may also transmit an additional tone of the PRACH using a random hopping distance. A receiving apparatus may receive the transmitted PRACH and determine a phase estimation based on the sets of tones having different hopping distances.
