20080239989 | Method of routing and resource allocation in a wireless communication system - 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). | 10-02-2008 |
20100240370 | METHODS AND APPARATUS FOR A MOBILE BROKER SUPPORTING INTER-RAT, INTER-OPERATOR HANDOVERS - 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. | 09-23-2010 |
20100322171 | RESOURCE BLOCK REUSE FOR COORDINATED MULTI-POINT TRANSMISSION - 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. | 12-23-2010 |
20110317664 | Method of performing an intra-segment handover - The invention concerns a method of performing an intra-segment handover (HO) of a mobile station (MS) from a source access point (AP | 12-29-2011 |
20130286968 | ALLOCATING CHANNELS FOR REAL-TIME TRAFFIC TRANSMISSIONS OF WIRELESS PACKET DATA AMONG MULTIPLE USERS - A method and an apparatus is provided for allocating channels in a multi-user environment for transmitting real-time data traffic in a wireless packet data network. The method includes determining an a priori data rate per channel for each of a plurality of mobile stations based on channel state information associated with a plurality of frequency channels associated with the plurality of mobile stations and a preliminary assumption of a uniform power distribution among the plurality of frequency channels at a transmitter. The method also includes allocating a unique frequency channel from said plurality of frequency channels to at least one of the plurality of mobile stations based on said a priori data rate per channel for each of the plurality of mobile stations. | 10-31-2013 |
