摘要： There is provided a mechanism for controlling communications conducted via different frequency bands or communication spectrums. When a communication via a first communication path, for example an unlicensed or white space communication spectrum, is to be established, e.g. for offloading traffic from a second communication path, for example a licensed cellular communication spectrum, a preamble transmission command is generated and transmitted from a communication network control element, such as an eNB, via the second communication path to a communication element, such as a UE. By means of the preamble transmission command, the transmission of a preamble signal by the receiving communication element on the first communication path with predetermined communication resources is triggered. Based on a receipt or non-receipt of the preamble signal via the first communication path, the communication network control element is able to determine that the communication element can establish a connection on the first communication path, for example the unlicensed or white space communication spectrum.

摘要： A method, apparatus and computer program product are provided to facilitate the determination of the timing advances of each of a plurality of component carriers by triggering the determination of the timing advances in response to certain pre-defined events that are indicative of a need for the timing advance to be determined. A method may include determining that a pre-defined event has occurred and triggering a determination of a timing advance for a second component carrier relative to a timing advance of a first component carrier based upon occurrence of the predefined event. In this regard, both the component carriers are concurrently allocated to a mobile terminal. The method may also utilize the timing advance to synchronize communications on the second component carrier between the mobile terminal and a network.

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.

摘要： Methods and apparatus are disclosed that facilitate discontinuous reception via a primary cell and one or more secondary cells that have different TDD UL/DL subframe configurations including overlapping subframes, such as in an instance in which a UL subframe of a secondary cell overlaps with a corresponding DL subframe of the primary cell. A method may define an active state of a primary cell to be larger than an active state of a secondary cell in a TDD network that supports carrier aggregation. The method may also provide for discontinuous reception via the primary cell and the secondary cell in accordance with different TDD UL/DL subframe configurations and also in accordance with the respective active states of the primary and secondary cells.

摘要： A downlink resource grant is on a first component carrier having a first downlink to uplink DL/UL subframe configuration, and cross schedules to a second component carrier having a different second DL/UL subframe configuration. If a first set SI of downlink subframes associated with a subframe n of the first DL/UL subframe configuration only partially overlaps with a second set S2 of downlink subframes associated with the subframe n of the second DL/UL subframe configuration, then explicit signaling is utilized to select whether uplink radio resources in subframe n for channel selection are implicitly or explicitly allocated. If instead SI does not only partially overlap SI, then a default rule is utilized for allocating the uplink radio resources in subframe n for channel selection. In different examples the explicit signaling is higher layer signaling which configures a UE; or a predetermined state in a field of the PDCCH.
