    Abstract: Embodiments are provided to serve user equipments (UEs) that experience, for example persistently, inter-transmission point group (TPG) interference in a wireless or cellular network. The embodiments include steps to serve edge UEs (EUs) such as persistent EUs (PEUs) using a set of transmission points (TPs) in one or more TPGs. The selected set of TPs used for serving the EUs or PEUs are dynamically determined based on a UE-centric metric. The metric involves the PEUs and surrounding UEs. The UE-centric metric is used to partition the network to multiple TPG sets. For each one of multiple assigned resource units (RUs), a TPG set that maximizes or improves a network-wide utility is used for scheduling transmissions. Further, for each RU, the UEs are associated with an optimized or improved TPG in the used TPG set.

    Abstract: A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.

  • Patent number: 8948770
    Abstract: The present invention discloses a cluster head assisted method for converting a user terminal from device-to-device (D2D) communication to cellular communication. When quality of a D2D link between a user terminal and a cluster head is lower than a predetermined threshold, if the user terminal has to leave the cluster but still expects to continue an original the service, the user terminal performs cell search and random access, and establishes a radio resource control (RRC) connection with a target base station of a cellular network. Switching from D2D communication to cellular communication is implemented with the assistance of the cluster head, and a communication manner after the switching is provided. The present invention implements mobile switching from D2D communication in distributed cluster communication to cellular communication, which can reduce route search delay and save wireless resources.

  • Patent number: 8948744
    Abstract: A spatio-temporal random voting scheme is provided that incorporates location distribution, spatial randomness, and temporal randomness in the collection of information from a plurality of sensing devices within the cognitive network. The region is divided into a plurality of sectors, where each sector is a portion of the region. A subset of sectors is selected from the plurality of sectors in the region to provide spatial randomness. A device is randomly selected from each sector in the subset of sectors to provide additional spatial randomness to the information collection process. Temporal randomness may be introduced by randomly selecting a timeslot within a sensing window period in which devices are to scan a frequency spectrum band to determine if a signal energy above a threshold is detected. Sensing reports are then collected from the selected sensing devices and used to determine whether the frequency spectrum band is available or in use.

  • Patent number: 8942129
    Abstract: A radio access network (RAN) may be configured to identify a set of wireless coverage areas in which to transmit inter-frequency search directives. Identifying the set of coverage areas may involve determining which of the coverage areas defined by the RAN have threshold weaker coverage on one carrier frequency than on another carrier frequency of that coverage area. For each coverage area of the set, the RAN may identify one or more WCDs operating in the coverage area that are operating on the coverage area's carrier frequency that has the weaker coverage. Based on the identifying of the WCDs, the RAN may send to each identified WCD an inter-frequency search directive to cause the WCD to scan for and report to the RAN a measurement of coverage on one or more carrier frequencies other than the carrier frequency on which the WCD is currently operating.

  • Patent number: 8942636
    Abstract: An adaptive scheme controls the transmission of interference management messages by wireless nodes. For example, the adaptive scheme may be used to determine whether and/or how to transmit resource utilization messages. Such a determination may be based on, for example, comparison of a quality of service threshold with a current quality of service level associated with received data. A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on the frequency at which the wireless node transmits resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on information received from another wireless node. An adaptation scheme also may depend on the type of traffic received by a given wireless node. A quality of service threshold also may be adapted based on throughput information.
