  • Patent number: 10015760
    Abstract: Methods and apparatus which allow a wireless terminal (302) to simultaneously maintain connections with multiple base stations (304, 306) are described. Each wireless terminal (302) is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (302, 306). In this manner base stations (302, 306) receive different data allowing for asynchronous data transmission. The data received by the base stations (302, 306) can be supplied to a wired asynchronous network (308) without the need to combine the received data prior to supplying it to the wired network (308). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

  • Patent number: 9491677
    Abstract: The invention described herein enables a form of downlink macro-diversity in packet-switched cellular networks. It allows packets to be selectively delivered from a network/internetwork to an end node, e.g., a wireless communication device or terminal, over a set of available link-layer connections to/from the end node, through one or more access nodes, e.g., base stations. Downlink macro-diversity is particularly important when the link-layer connections between the end node and the corresponding access node, e.g., the access links, are subject to independent or partially correlated time variations in signal strength and interference. In accordance with the invention, the end node dynamically selects the downlink to be used out of a set of available access links on a per packet basis subject to prevailing channel conditions, availability of air-link resources and other constraints.

  • Patent number: 9191840
    Abstract: A wireless terminal receives a broadcast uplink interference report request conveying a requested report type and/or a locally unique base station identifier. The wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. Specific type interference reports relate a current serving connection base station attachment point to a selected base station attachment point corresponding to the received base station identifier. Generic type interference reports relate a current serving base station connection attachment point to other unspecified base station attachment points whose broadcast reference signals have been detected by the wireless terminal. Sub-types of generic reports include summation function and maximum function reports. Timing information is sometimes used to determine report sub-type and/or sector type of the selected attachment point.

  • Patent number: 8804677
    Abstract: Methods and apparatus for establishing communications between devices, e.g., mobile communications devices in an ad hoc network, with differing capabilities are described. A device which is capable of supporting multiple protocols in addition to a protocol used to communicate device capability information forms communications links with first and second devices which do not have the ability to form communications links directly between one another, e.g., because of they do not support the same protocols. Once the links are established the first and second devices can communicate via the third communications device. In some embodiments, each of the first, second and third devices support a first communications protocol which is suitable for communicating device capability information but is unsuitable for exchanging user data. The ability to discover other devices and there capabilities facilitates the creation of an ad hoc network.

  • Patent number: 8693372
    Abstract: Methods and apparatus related to routing in communications networks are described. Various embodiments are well suited to wireless communications systems lacking centralized control, e.g., a mobile wireless communications system supporting the dynamic formation and/or maintenance of overlapping peer-to-peer ad hoc networks. A node can establish multiple links, e.g., with different links corresponding to different overlapping networks. Next hop packet routing information, e.g., forwarding tables, are maintained on a per network basis. A node determines the next hop routing for a received packet to be forwarded based on the link upon which the packet was received, which is associated with a particular network, and the included packet destination address. The same destination address may, and sometimes does, correspond to different next hop nodes for different networks.

  • Patent number: 8665734
    Abstract: A method and apparatus for providing uplink macro-diversity in packet-switched networks that allows packets and/or portions of packets, e.g., frames, to be selectively sent from an end node, e.g., wireless communication device or mobile terminal, over a set of multiple communication connections, e.g., physical-layer or link-layer connections, to one or more access nodes, e.g., base stations. Uplink macro-diversity is achieved in part through intelligent selective forwarding over multiple communication connections, where the forwarding decision is controlled by the end node based on a variety of factors, e.g., physical-layer channel conditions and/or higher layer policy. The forwarding decision is executed on a rapid timescale, e.g., on a per packet basis, to adapt to the dynamically varying conditions of the set of communication connections.

  • Patent number: 8565801
    Abstract: Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the access node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment.

  • Patent number: 8504099
    Abstract: Methods and apparatus for selecting and switching between cooperative and non-cooperative modes of communications device operation are described. Switching between modes may be, e.g., in response to a signal received form another device or in response to another device leaving the area. In cooperative mode operation the communications device acts in a manner that takes into consideration the effect of signal transmissions on other devices, e.g., the device may respond to interference control signaling, resource allocation signals and/or implement other interference management techniques. In the non-cooperative mode the device seeks to optimize its own communications performance without regard to the effect on one or more communications devices which may be in the area, e.g., devices with which it is not communicating. In the non-cooperative mode the device may ignore interference management control signals or transmit signals intended to cause another devices to reduce their transmissions or power output.
