  • Publication number: 20110076957
    Abstract: In a radio communication system having a plurality of network-side radio stations, a first network-side radio station sends signals to subscriber stations of the radio station information relating to other network-side radio stations. The subscriber stations carry out measurements on the signals of network-side radio stations indicated in the radio station information. The first network side radio station sends workload information relating to the workload of at least some of the network-side radio stations indicated in the radio station information.

  • Patent number: 7742779
    Abstract: A method synchronizes a radio communication system that is divided up into radio cells. According to the method, every radio cell has one base station each for the radio coverage of a plurality of mobile stations assigned to the radio cell. The base station receives, in addition to mobile station signals of its own radio cell, mobile station signals of neighboring radio cells. The base station determines, on the basis of the mobile station signals received, the number of mobile stations and compares this number with a defined threshold value. When the number determined falls below the threshold value, a first synchronization method for synchronizing the base station and the assigned mobile stations is used, the first method corresponding to an assigned transmission standard of the radio communication system. When the threshold value is exceeded, a second synchronization method is used for synchronizing the base station and the assigned mobile stations.

  • Publication number: 20050034737
    Abstract: This invention relates to the treatment of tobacco and tobacco smoke with chelating agents to reduce the concentration of Pb-210 and Po-210. Chelating formulations such as the tetrasodium salt of ethylenediaminetetraacetic acid in aqueous solution with a wetting agent are sprayed onto the tobacco during growth and/or the chelating formulations are used to soak or wash the tobacco after harvest but before curing the tobacco. Pb-210, Po-210 and other metals are removed from tobacco smoke by applying chelating agents to the surface of the tobacco and/or the filter material.
