    摘要: There is proposed a mechanism for controlling and conducting a discovery procedure of small cells or secondary cells located in a macro cell or primary cell. The discovery procedure is based on a discovery signal communicated via PDCH and based on a positioning reference signal (PRS). For configuring the signaling of the discovery signal, frequency domain multiplexing for splitting resources of the PRS in the frequency domain for increasing capacity, and/or usage of reserved communication resources for the signaling of the discovery signal are employed. Assistance information is provided to the UE for supporting the discovery of small cells.

    摘要: A method, apparatus and computer program product are provided for generating Reference Signals utilized in downlink tracking of an unlicensed band. A method and apparatus may determine whether carriers of an unlicensed band secondary component carrier are available for usage to provide a signal(s), enabling timing and frequency tracking of downlink carriers responsive to discontinuous transmission via a medium(s) of the unlicensed band utilized to provide content to devices. The method and apparatus may also select the signal based on a band of the carriers and a detection indicating whether communication terminals of a coexisting system are using a carrier of the band. The method and apparatus may provide the signal to a device(s) via a carrier responsive to determining that the carrier is available or via an occupied carrier utilized by the coexisting system enabling the device to continue tracking of timing and frequency information of the downlink carriers.

    摘要: A user equipment UE determines at least one first set SI of physical resource blocks PRBs, and detects downlink signaling within search spaces of set(s) SI. Through that downlink signaling the UE obtains a configuration for a downlink control channel, and that configuration indicates at least one second set S2 of PRBs and at least one search space specific for the UE which lies within S2. The UE utilizes the obtained configuration to monitor at least some of the search spaces of SI and the at least one search space specific for the UE of S2 for further downlink control signaling. Multiple implementations are detailed for how the UE gets SI. This invention is particularly useful for a configurable ePDCCH region in a stand-alone carrier where the UE is not able to get the new configuration from some other carrier such as a PCell whose configuration does not change.

    摘要: A method, apparatus and computer program product are provided facilitating flexible time sharing among systems. A method and apparatus may generate a secondary component carrier transmission plan including planned on and off durations. The planned on durations correspond to a time period for an apparatus and devices to communicate via an unlicensed band of the secondary component carrier. The planned off durations correspond to a time interval in which the devices may deactivate from the unlicensed band or remain disconnected from the unlicensed band. The method and apparatus may also enable provision of the plan to the devices via a licensed band of a primary component carrier and detecting a medium of the unlicensed band prior to the expiration of the time period to determine whether the medium is available in order to decide whether to turn on transmissions to the unlicensed band after one of the planned off durations.
