Methods and apparatus for operating in a wideband communication system

Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

System and methods for controlling out-of-network D2D communications

A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.

A system and method of scheduling transmissions. A wireless device such as an eNodeB (eNB) may schedule a transmission of a wideband (WB) signal on a micro-frame selected from a plurality of WB micro-frames of a WB carrier. A narrowband (NB) subframe may span a portion of the selected WB micro-frame in the frequency-domain, and the selected WB micro-frame may overlap at least a portion of the NB subframe in the time-domain. The WB signal and an NB signal may be transmitted over the WB micro-frame and the NB subframe in accordance with a first numerology and a second numerology, respectively. A WB subframe may be divided into a plurality of micro-frames. The transmission direction of the WB micro-frame may be scheduled according to a transmission rule based on the contents of a payload in the NB subframe.

Traffic data is divided into data streams corresponding to workloads, and the data streams are multiplexed onto slice segments based on a multiplexing requirement or rule. Each slice segment is a physical or virtual processing element in a wireless network supporting network slicing. In one example, the data streams are multiplexed onto the slice segments such that data streams having different utility definitions are assigned to different slice segments. In another example, the data streams are multiplexed onto the slice segments such that workloads in the same cluster partitioned in a T-dimensional vector space are assigned to different slice segments.

A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.

Embodiments are provide for communicating data or other non-control information messages within a downlink control channel directly, rather than in a data channel or broadcast channel. Thereby, radio resource utilization can be substantially improved in the cellular system, such as in the case of transmitting smaller data packets. In an embodiment, a transmitter arranges a set of time-frequency radio resources, associated with a downlink control channel, for transmitting information other than control information sent on the downlink control channel. The transmitter then sends, on the set of time-frequency radio resources, a data information message comprising the information other than the control information. The information other than the control information comprises one of user-specific data information and broadcast data information. A receiver then receives on the downlink control channel, control information and the data information message.
