Abstract: Methods and apparatus that enable a wireless femtocell to operate in its designated frequency so as to minimize interference between the wireless femtocell and neighboring base stations (and other femtocells or nomadic cells). In one exemplary embodiment, the femtocell cell comprises a UMTS (Universal Mobile Telecommunications System) femtocell which has the ability to scan the air interface in a manner similar to that associated with a UE in order to identify unallocated resources within the wireless network, and subsequently request access for the unallocated resources. Business methods useful in combination with the aforementioned methods and apparatus are also disclosed.

Abstract: Methods and apparatus that enable a wireless network system to dynamically change between full-duplex FDD operation and half-duplex FDD operation in order to take advantage of operational aspects of both modes. In one embodiment, an alternative duplex mode of operation is disclosed (semi-static half duplex FDD operation) that enables coordination between the client device (e.g., UMTS UE) and the base station in order to centralize control of radio resource control (RRC) to the base station. The disclosed methods and apparatus may also advantageously incorporate hybrid ARQ (HARQ) or comparable timing requirements into their operation.

Abstract: Methods and apparatus that reduce network management overhead required for the operation of wireless femtocells. In one aspect of the invention, a central network entity governs the simultaneous operation of several femtocells by specifying modes of operation, and operational parameters for one or more of the femtocells. In one embodiment, at least one of the specified modes of operation directs a femtocell to operate in a substantially autonomous manner within the network-defined operational parameters. The network-defined constraints are provided to the femtocell for example, responsive to a successful registration attempt.

Abstract: Methods and apparatus for providing enhanced access options for wireless access points (e.g., cellular femtocells). These access options in one embodiment include various grades or levels of private and public access to available femtocell services. Each service may be separately assigned a various access type, such that a femtocell may service multiple users both within the “closed” group authorized by the femtocell white list, and non-members. In one variant, a femtocell broadcasts enhanced system information to all terminals (regardless of member/non-member status) such that a non-CSG (Closed Subscriber Group) member terminal or UE is capable of obtaining partial service access within the femtocell. Broadcast multimedia or other services can be delivered to both CSG members and non-members, advantageously without having to establish a dedicated connection for the non-member users.

Abstract: Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms are limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

Abstract: Methods and apparatus that enable and optimize the simultaneous operation of several wireless femtocells having overlapping coverage areas. In one embodiment of the invention, a resource allocation (e.g., time-frequency grid for an OFDM or TDMA based wireless network) governs the simultaneous operation of several femtocells with overlapping coverage areas by specifying uses for resources. A resource allocation unit (RAU) entity is disclosed for managing and modifying resource allocations for femtocells. The community of femtocells can flexibly share resources according to the time-frequency grid, thereby maximizing spectral efficiency without requiring substantial network overhead.

Abstract: Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, precoding (e.g., Tomlinson-Harashima precoding) can be applied to “shape” the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.
