  • Patent number: 8498258
    Abstract: According to one example embodiment, a method may include receiving, by a first femto base station via a femto base station air interface, at least one neighbor preamble from at least one neighbor femto base station. The method may further include sending, by the first femto base station to a macro base station via a guided (DSL) Internet connection, an interference report, the interference report being based at least in part on the at least one neighbor preamble received from the at least one neighbor femto base station. The method may further include receiving, by the first femto base station from the macro base station via the guided Internet connection, a resource allocation message. The method may further include sending, by the first femto base station via the femto base station air interface, a first femto base station preamble, the first femto base station preamble being sent at a time determined at least in part by the resource allocation message.

  • Publication number: 20110141905
    Abstract: A network node, a mobile device, a communication system, a method for detecting the type of a network node, the method for transmitting the type of a network node and the use of a data frame for determining the type of a network node is described. To distinguish between different types of network nodes, a signal pattern including an attribute is transmitted/received. The attribute is type-indicative of the type of the network node. Different ways of implementing the type-indicative attribute are described.

  • Publication number: 20110080863
    Abstract: The present invention relates to methods and apparatuses for providing selective network access, wherein a cell type indication is provided based on at least one of a preamble and a header portion of a broadcast signal. At the receiving end, it is checked based on at least one of the preamble and the header portion, whether broadcast signals are received from different first and second cell types. The first cell type is selected for network access, if both broadcast signals from the first and second cell types are received with sufficient strength.

  • Patent number: 7830916
    Abstract: A method is described which includes allocating transmission resources for transmitting data packets. The allocation of transmission resources includes a periodic allocation of the transmission resources that is applicable to a plurality of frames. The allocation of transmission resources includes an allocation of transmission resources for a first transmission of each HARQ process during the plurality of frames. The method includes receiving an indication of an allocation of transmission resources for data packets in a plurality of frames. Receiving and/or transmitting packets during the plurality of frames using the allocation of transmission resources is also included in the method. The frames in the plurality of frames may include a compressed MAC header. Apparatus and computer programs are also described.

  • Publication number: 20100182932
    Abstract: Exemplary embodiments of this invention provide a reduction in signaling overhead by allocating radio resources to subscriber stations (SSs) based on a group of connection identifiers (CIDs), where the group corresponds to a plurality of connections. The use of these exemplary embodiments can be particularly beneficial for certain applications, such as voice over internet protocol (VoIP) applications, by removing unnecessary signaling overhead. In one exemplary embodiment of the invention, a method includes: receiving signaling that assigns a subscriber station to a particular group of subscriber stations or that removes an already assigned subscriber station from the particular group of subscriber stations; and transmitting an acknowledgment that confirms receipt of the signaling.

  • Publication number: 20090154412
    Abstract: A method includes allocating channels in a fast-feedback channel region for a plurality of devices, and transmitting to the plurality of devices at least one bitmap defining fast-feedback uplink channel allocations for individual ones of the plurality of devices. In one embodiment a plurality of bitmaps are transmitted, the plurality of bit maps together informing individual ones of the plurality of devices of permission to use none, one or more than one particular fast-feedback channel. In this case each bitmap includes a plurality n of bit positions corresponding to n indices, where each device is identified by an associated one of the n indices, and where a bit at an index value p in a first bitmap and a bit at the same index value p in a second bitmap, when concatenated together, equal a number of fast-feedback uplink channels that are allocated to a particular device associated with the index value p.
