  • Publication number: 20160037432
    Abstract: A network has a central entity connected to a plurality of capillary networks and external networks. Information regarding the capillary networks and the external networks may be fused in the central entity to provide assistance services and network control to one or more of the capillary networks. The information may be collected from the capillary networks using a logical interface with a common upper layer coupled to multiple Radio Access Technologies (RATs). The central entity configures an internal communications network including a plurality of disparate devices, and recognizes and communicates with each device within the internal communications network by discovering each new device as introduced into the internal communications network. A communication link can be set up with reconfigurable or capable devices to exchange information possibly in another format in another band. The same communication link can be torn down after completion of the service.

  • Patent number: 9247509
    Abstract: A method of generating an index value associated with a primary synchronization code within a communication signal includes splitting a sampled communication signal into even and odd samples. The even and odd samples are correlated with a primary synchronization code of the communication signal and complex values of the even and odd samples are generated. Signal strength values for the even and odd samples are approximated and the approximate signal strength values within a frame of the communication signal are accumulated. A highest accumulated signal strength value is assigned as an index value.

  • Publication number: 20150271834
    Abstract: Described herein are methods, metrics and apparatus for bandwidth allocation for cognitive radio. Information that needs to be passed between different components of a dynamic spectrum management (DSM) system for dynamic bandwidth allocation along with the corresponding interfaces is identified. Methods and associated metrics for measuring network performance, evaluating channel sensing results and handling various bandwidth allocation scenarios are presented. Also provided is an admission control mechanism for quality of service support. Alternate channel monitoring may be performed in the background so that when a new channel is needed, an alternate channel may be immediately allocated and service disruption to the DSM system is reduced. A channel may be dynamically assigned as the primary channel in multiple channel scenarios to support tasks such as transmission of acknowledgment frames.

  • Patent number: 9007939
    Abstract: A method and apparatus for a secondary wireless transmit/receive unit (WTRU) to use of secondary cellular spectrum are provided. The secondary WTRU monitors transmissions of a primary WTRU; determines whether to provide assistance to the primary WTRU; and in response to a determination to provide assistance, performs cooperative communications with the primary WTRU for its transmission of data to a base station. If the assistance results in the data being transmitted to the base station faster than it would have with out assistance, the secondary WTRU may utilize uplink resources originally intended for the primary WTRU.

  • Publication number: 20140199992
    Abstract: Systems, methods, and instrumentalities are disclosed to schedule user equipment (UE) measurements. An HeNB may identify a first cluster of UEs and a second cluster of UEs. The HeNB may determine a measuring gap schedule relating to the first cluster of UEs and the second cluster of UEs. The measuring gap schedule may indicate a measurement time for each cluster. The measurement time may indicate that UEs in a cluster withhold a transmission during the measurement time. The UEs in the cluster may measure a spectrum (e.g., frequency, channel, etc.) associated with a supplementary cell during the measurement time. The HeNB may send the measuring gap schedule to the first cluster of UEs and the second cluster of UEs. The HeNB may receive spectrum measurements of the supplementary cell from the first cluster of UEs and the second cluster of UEs, e.g., in accordance with the measuring gap schedule.

  • Publication number: 20140161002
    Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

  • Publication number: 20140105139
    Abstract: Systems and methods for integrating bandwidth management (BWM) equipment into a network in order to manage the use of bandwidth over multiple radio access technologies (RATs) relating to communications between a wireless transmit receive unit and a mobile core network (MCN). When integrating itself into the network, a BWM server may be placed between a MCN and an femto access point. In order for WTRUs to communicate with the MCN through the femto access point and a BWM server, a BWM server may need deep packet inspection capabilities.

  • Publication number: 20140086081
    Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.
