An apparatus operable in a communication system is described. The apparatus includes means for receiving a neighbor relation message from another apparatus. The apparatus also includes means for generating cluster information based on the neighbor relation message. The apparatus further includes means for transmitting the cluster information to the other apparatus.

Apparatus for clustering cells using neighbor relations

Methods, apparatus and computer program products are provided to improve the efficiency of resource allocation in wireless communication networks. In one provided embodiment, a wireless communication device determines a received signal strength of each of a number of signals received from a number of transmission sectors, provides first channel information for first signals including a signal having a highest received signal strength and signals having a received signal strength above a specified level relative to the highest received signal strength, provides second channel information for second signals including signals having a received signal strength below the specified level, and receives an allocation of one or more resource blocks from assigned transmission sectors based on a ranking of the first channel information, whereby the one or more resource blocks are reallocated to another wireless communication device, from another transmission sector, based on the second channel information. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

Resource block reuse for coordinated multi-point transmission

A method for determining an optimal access network by an apparatus is described. The method may include communicating with a first base station as part of a first access network using a first radio access technology (RAT). Information about access networks available to the apparatus may be received from a mobile broker. An optimal access network and the corresponding optimal RAT may be selected based on the received information. The method may also include switching to communications with a second base station using a second RAT.

Methods and apparatus for a mobile broker supporting inter-rat, inter-operator handovers

The invention concerns a method of performing an intra-segment handover (HO) of a mobile station (MS) from a source access point (AP) of a tree-structured segment (S) of an Ethernet-compliant telecommunication network to a target access point (AP) of said segment (S), as well as a switch (SW-) to support the execution of this method. After establishing contact between the mobile station (MS) and the target access point (AP), the mobile station (MS) sends an update entry request addressed to the segment gateway switch (GW). The update entry request is received by a switch (SW-) positioned in the tree structure of the segment (S) hierarchically above the source and target access points (AP, AP) and below the segment gateway switch (GW). The switch (SW-) checks whether its forwarding database contains a first entry comprising an address of the mobile station (MS) received by means of the update entry request. If the forwarding database of the switch (SW-) contains the first entry, the switch (SW-) squelches said update entry request and assumes the function of an anchor switch regarding the handover (HO), whereby the anchor switch is a switch of the segment (S) which is positioned in the tree structure of the segment (S) hierarchically above the source and target access points (AP, AP) and below the segment gateway switch (GW) and which is common to the ongoing session before and after the handover (HO).

Method of performing an intra-segment handover

The present invention provides a method for route and resource allocation. One embodiment of the method includes determining at least one network variable associated with a network that includes a plurality of nodes connected by a plurality of links. The network variable(s) are determined based on a plurality of basic loads associated with the plurality of links and a plurality of data rates associated with the plurality of links. The method also includes determining at least one communication variable based on the determined network variable(s) and allocating at least one resource for communication over the network based on the determined network variable(s) and the determined communication variable(s).

Method of routing and resource allocation in a wireless communication system

A method and an apparatus for allocating channels in at least one of a multi-user and a multi-service environment for transmitting real-time traffic data in a wireless packet data network is provided. The method comprises determining a desired transmission rate for a first mobile station to allocate a unique frequency channel from a plurality of frequency channels to an individual user of a plurality of users. The method further comprises mapping a data stream associated with the individual user to the unique frequency channel based on the desired transmission rate for the first mobile station. A transmitter may allocate channels for transmitting real-time traffic data in a wireless communication system. The transmitter may comprise a plurality of encoders to independently encode data streams of each individual mobile station user of a plurality of mobile station users, a first resource allocator coupled to the plurality of encoders to allocate bit and power to the plurality of mobile station users, and a second resource allocator coupled to the plurality of encoders to allocate a unique frequency channel of a plurality of frequency channel to each mobile station user of the plurality of mobile station users based on at least one of channel state information and a desired transmission rate.
