  • Publication number: 20190140810
    Abstract: A wireless transmit/receive unit (WTRU) may receive a first transmission in a first band of a first Federal Communication Commission (FCC) spectral block using orthogonal frequency division multiplex (OFDM). The first transmission may include reconfiguration information. The WTRU may receive, in response to the reconfiguration information, a second transmission in a second band of a second FCC spectral block using OFDM. The WTRU may receive, based on a dynamic assignment, transmissions in the first band and the second band.

  • Patent number: 10219318
    Abstract: Techniques for supporting utilization of femtocell service capabilities for services are disclosed. A network device may be configured to implement a femto services gateway. The femto services gateway may reside in a femtocell and provide application programming interfaces (APIs) to services to enable applications implementing the services to make use of functionalities of femtocell service capabilities. The APIs may be a subset of or an extended set of Open Service Access Parlay or Parlay-X APIs. The services may be either femtocell-hosted, mobile network operator core network-hosted, or Internet-hosted. The femtocell service capabilities may include a framework service capability feature (SCF), a call control SCF, a user interaction SCF, a mobility SCF, a terminal capability SCF, a data session control SCF, a connectivity manager SCF, an account management SCF, a charging management SCF, a policy management SCF, a presence and availability management SCF, or a multimedia messaging SCF.

  • Patent number: 9942007
    Abstract: A method and apparatus for time-based fast positive acknowledgement (ACK)/negative acknowledgement (NACK) reporting (FANR) operation with enhanced general packet radio service 2 uplink (HUGE) are disclosed. A wireless transmit/receive unit (WTRU) configures downlink FANR operation and EGPRS-2 mode uplink transmission not to be in conflict. A modulation and coding scheme (MCS) for the EGPRS-2 mode may be limited to an MCS containing at most two RLC data blocks. Alternatively, three or more piggybacked ACK/NACK (PAN) bits may be used for a time-based FANR operation if an EGPRS-2 mode is configured. Alternatively, at least one PAN bit may indicate an ACK/NACK for a group of RLC data blocks. The number of PAN bits for a time-based FANR operation may be configured by the network. The downlink FANR operation may be dynamically switched between time-based and SSN-based.

    Abstract: Methods, systems and apparatus for managing and/or enforcing one or more policies for managing internet protocol (“IP”) traffic among multiple accesses of a network in accordance with a policy for managing bandwidth among the multiple accesses are disclosed. Among the methods, systems and apparatus is a method that may include obtaining performance metrics associated with the multiple accesses. The method may also include adapting one or more rules of one or more the policies for managing IP traffic among the plurality of accesses based, at least in part, on the performance metrics and the policy for managing bandwidth among the plurality of accesses. The method may further include managing IP traffic associated with at least one wireless transmit and/or receive unit (“WTRU”) among the plurality of accesses responsive to the adapted rules.
