Abstract: Downlink common control information communicated in a first network (such as a macro network or a small cell) between a first/macro access node and a user equipment UE is mapped to an uplink resource. The first/macro access node and UE then tune to the mapped uplink resource to send or receive dedicated control information about the UE concerning a second network (an underlay network such as a femto CSG or D2D network). In one embodiment the DCI may be within a downlink assignment indicated by P-RNTI, RA-RNTI, or SI-RNTI; and the mapping uses a control channel element which carries the P-RNTI or the RA-RNTI or the SI-RNTI. In another the mapped uplink resource is a format 1a or format 1b PUCCH and the common control information requires neither an acknowledgement nor a negative acknowledgement. The dedicated control information may inform about interference experienced by the UE with the second network.

Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring/implementing by a network/network element a partial full-duplex in time dependent operational mode for wireless communications between UEs and the network/network element, e.g., in LTE systems. The time dependent partial full-duplex may further include bandwidth allocations for the full-duplex and half-duplex time intervals. In the half-duplex time periods, undesirable interference and self-interference effects during signal detection by the UEs and/or eNBs may be reduced to an advantage. The network may configure a time dependence of the partial full-duplex operational mode for wireless communications between UEs and the network, wherein during at least one time interval the network configures a full-duplex operational mode and during at least one other time interval the network configures a half-duplex operational mode for the wireless communications between the UEs and the network.

Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for implementing a cellular oriented mechanism such as Random Access (RA) mechanism to support device-to-device (D2D) discovery procedure and D2D connection setup for a direct D2D communication of cellular devices such as UEs, e.g., in LTE wireless systems. The network can provide D2D uplink resource(s) to UEs for setting the D2D communication based on a RACH preamble (e.g., mapped according to a predefined procedure from the discovery signal) received by the network from the UE.

Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for discovery of D2D devices in wireless communications, e.g., LTE systems by relating beacon/discovery resources to paging frames, so that the UE may save power being active (e.g., in the wake-up state) only during paging frames. The user equipment may receive during a paging receiving time a paging signal from the wireless network and at least one discovery signal from at least one user equipment operating in the wireless network, wherein a discovery cycle period of the at least one discovery signal is different than the paging cycle period and is determined using the paging cycle period based on a predefined rule.

Abstract: A fixed or Mode II device enables a Mode I device for license exempt operation by providing to it a list of available license exempt radio channels and a parameter indicating an interval at which contact verification signals CVSs are to be sent. The CVSs verify whether the list remains valid. The fixed/Mode II device then repeatedly sends contact verification signals spaced in time from one another according to the interval. In various embodiments the parameter may be an explicit indication (number of seconds or number of beacons between consecutive CVSs), or it may be implicit (derived from an ID of the fixed/Mode II or Mode I device or a frequency channel, in which the relevant ID is the parameter). A plurality of enabled Mode I devices each gets a device-specific list, and in one embodiment the interval is the same for each of them and the explicit indication is broadcast while in another the parameter is provided to each of them via unicast messages and the interval may differ.

Abstract: In an exemplary embodiment there are determined which radio resource are to be used for contention based access, and the allocated radio resource is accessed according to a probability function that varies in dependence on at least one of interference measured on the allocated radio resource and a received power level for the allocated radio resource. By example the radio resource is allocated by a cellular base station for use in D2D communications; the base station provides configuration parameters for the D2D communications via common or dedicated signaling; the received power level is a target received power level that is received via broadcast system information or dedicated control signaling; and/or the received power level is itself a function of pathloss on a wireless link to the cellular base station. Embodiments are presented for method, apparatus, and tangibly stored computer program.
