Abstract: A wireless device transmits a device-to-device discovery signal using the same transmission resource that is used for transmitting uplink retransmissions to a base station by a second wireless device. The device-to-device discovery signal is transmitted at a power that is determined in accordance with a control signal received by the wireless device from the base station. In an example, the wireless device transmits the device-to-device discovery signal on an uplink control channel established for use for sending uplink control signals to the base station.

Abstract: The invention relates to the radio interface between an apparatus for wireless communication and a network element, comprising flexible uplink/downlink configuration for time division duplex. The method comprises detecting a parameter indicating interference in a subframe of a time division duplex configuration; assigning a priority Physical Resource Block set for a flexible subframe; and scheduling the connection for a wireless apparatus according to the priority Physical Resource Block set.

Abstract: An apparatus, method and system for dynamic resolution of secondary communication system resources for communications in a communication system. In one embodiment, an apparatus includes a processor and memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to receive an allocation of secondary communication system resources on a control channel of a primary communication system to enable communication in a secondary communication system. The secondary communication system resources are a function of unused primary communication system resources in the primary communication system.

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 present invention proposes an apparatus, including a communication module, configured to communicate with another apparatus in a first mode, which involves at least one network device in order to establish end-to-end communication between the apparatus and a communication counterpart, or in a second mode, which establishes direct end-to-end communication between the apparatus and a communication counterpart not involving a network device, wherein communication is based on physical resources that are allocated in time and frequency domain based on a resource grid, and a control module, configured to control the communication module to communicate in the first mode based on a first resource grid pattern or to communicate in the second mode based on a second resource grid pattern. Likewise, the present invention addresses a correspondingly adapted network entity, as well as respective methods and computer program products.
