    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: Systems and techniques for managing the use of industrial-scientific-medical bands for cellular network communication. An apparatus comprises a processing system and a memory storing a set of program instructions. The processing system is configured to cause the apparatus to receive channel information from a UE reporting the control of an industrial-scientific-medical (ISM) band channel by the UE and cause the apparatus to schedule a communication session with the UE over the channel, with the channel being configured and activated as an ISM secondary component carrier (SCC). The apparatus may further request one or more user equipments (UEs) to report their wireless fidelity (WiFi) capability and request user equipments having WiFi capability to compete for the wireless medium and report occupation of the wireless medium in the form of a request to send command, to which the apparatus responds with a clear to send command.

    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 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.

    摘要: An aggressor access node in a heterogeneous network sends to a victim access node a pattern of transmit power for designated low-interference subframes (e.g., LP-ABSs). Utilizing feedback information collected from the victim node which quantizes interference seen by user equipments (UEs) which are allocated at least some of those subframes, the aggressor node selects whether and how much to adjust transmit power for subsequent such subframes, then sends to the victim node a pattern of the adjusted transmit power for those subsequent subframes (e.g., an enhancement to relative narrowband transmit power RNTP). The victim node sends to UEs the pattern of transmit power and respective resource allocations in those designated low-interference subframes; then derives interference level per UE in those subframes based on channel quality indications received from the respective UEs; and sends to the aggressor access node feedback information which quantizes the derived interference levels.
