  • Patent number: 10582332
    Abstract: The present disclosure generally discloses an autonomous localization capability configured to determine the localization of a mobile device of a wireless communication network based on a sequence of observations reported by the mobile device and a model that represents the motion and observations of mobile devices of the wireless communication network. The model that represents the motion and observations of the mobile devices may be a Hidden Markov Model (HMM) constructed based on use of localization information to define the hidden states of the and use of signal strength measurement reporting information to define possible observations. The localization problem for determining a localization of a given mobile device then becomes a maximum a posterior problem represented by the HMM, which may be solved using a particle filter based localization algorithm using localization probability distribution information which may be determined based on signal strength measurement reporting information.

  • Patent number: 8442442
    Abstract: Example methods use secondary scrambling codes in telecommunications networks. The secondary scrambling codes are assigned to mobile stations and channels used by mobile stations that are not adversely affected by the use of secondary scrambling codes. By assigning secondary scrambling codes additional users can utilize telecommunications networks with unique scrambling codes without reducing quality of service or increasing resource consumption. Example methods also reduce interference between mobile stations in the telecommunications networks.

  • Patent number: 8254318
    Abstract: A wireless communication system and joint beamforming method across multiple base stations for communicating with mobile stations. The wireless communication system communication system includes base stations and mobile stations. At least one of the base stations includes a joint beamformer controlling beamforming for the base stations. Each of the mobile stations receive information from the base stations, maintain a multiple-input and multiple-output active set (MAS) of base stations, and provide precoder weights to each of the base stations included in the MAS. The joint beamformer calculates joint beamforming weights for controlling communications between the base stations and mobile stations.

  • Patent number: 8189453
    Abstract: Improvements are provided in an OFDM network that uses superposition coding. A broadcast signal and e.g. a unicast signal are each subjected to OFDM modulation including processing by an IDFT, combined, and transmitted using non-orthogonal transmission resources. In one approach, the respective signals are combined after instead of before the IDFT processing. In specific examples, a respective cyclic prefix is appended to each signal after the IDFT processing but before the respective signals are combined. In another approach, a broadcast pilot signal and e.g. a unicast pilot signal are transmitted concurrently with the broadcast and unicast information signals. The pilot signals are transmitted using the same time and subcarrier resources, but are made more distinguishable by combining each with a respective scrambling or spreading code. In specific examples, embodiments, the unicast pilot signal is used for estimating the data rate for transmission of further unicast information signals.

  • Patent number: 8159974
    Abstract: One embodiment includes monitoring, for each communication node, at least one factor of interest and a plurality of potential influencing factors associated with the factor of interest. The factor of interest characterizes an operating condition of the communication node, and the plurality of potential influencing factors each have a potential influence on the operating condition. For each factor of interest for each communication node, a predictor coefficient for one or more of the potential influencing factors associated with the factor of interest is determined. The predictor coefficient indicates a predicted level of influence the potential influencing factor has on the factor of interest. For each communication node, interfaces are configured between the communication node and other communication nodes based on the determined predictor coefficients.

  • Publication number: 20110238552
    Abstract: To address the need to fairly allocate resources to a number of competing and heterogeneous consumers, embodiments such as those depicted in diagram 100 may be employed. A dynamic resource access (DRA) manager receives (101) a bid for a wireless resource from each bidder of a group of bidders, each bid including a bid price. Each bidder in the group of bidders is ranked (102) based on bid price and a quality of service associated with that bidder. The wireless resource is then allocated (103) to the highest ranked bidder of the group of bidders at the bid price of the second highest ranked bidder of the group of bidders.
