  • Patent number: 8576694
    Abstract: An apparatus, method, and system for dynamically assigning orthogonal codes to different information signals communicated between a Node B and user equipment in a cellular radio communication system in which a fixed number of codes are allocated between dedicated transport channels (DCHs) and high speed downlink shared channels (HS-DSCHs). A radio controller (RNC) allocates a minimum number of codes for HS-DSCH physical channels (HS-PDSCH codes) to the Node B. The Node B determines HS-PDSCH codes that are not currently being utilized and allocates HS-PDSCH codes from the unused codes without having to communicate with the RNC. When the additional HS-PDSCH codes are needed for DCH codes, the Node B reallocates the codes for DCH purposes without reducing the number of HS-PDSCH codes below the allocated minimum.

  • Patent number: 8358979
    Abstract: A method for facilitating noise and interference measurements on an air interface of a wireless network includes obtaining information relating to a time-varying layout of a silent resource element (RE) grid and taking a presence of a silent RE grid into account in the reception of a control or a data channel.

  • Patent number: 7873362
    Abstract: A simple and reliable method for dimensioning CDMA based networks is achieved by a method for evaluating or dimensioning a radio network comprising the steps of—defining a radio network model comprising at least one radio base station and a plurality of mobile terminals, —for each mobile terminal in the model, defining a path gain value for a signal path between the mobile terminal and each of the radio base stations, said method being characterized by the steps of—for each mobile terminal, selecting at least one of said path gain values, —defining a data set comprising at least one parameter based on said selected at least one path gain value for each mobile terminal, and—performing dimensioning calculations on the data set. Especially if data sets are prestored the dimensioning calculations can be carried out in very short time.

  • Publication number: 20100214966
    Abstract: The present invention relates to a base station and a method in a mobile communication network comprising means for transmitting information to User Equipments (UEs), on a first channel and means for transmitting data packets to said UEs on a second channel. The timing of the first channel and second channel is overlapping, and the base station comprises means for setting individual power levels of the first channel for each scheduled UE. The base station according to the present invention comprises means for setting the power level of the second channel for a first scheduled UE based on the power level setting for the first channel for at least a subsequently scheduled second UE based on an early UE scheduling decision.

  • Publication number: 20100197330
    Abstract: A receiving unit or a transmitting unit of a wireless network, for facilitating noise and interference measurements on an air interface. The receiving unit includes: a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid; an electronic memory having code in communication with the network interface which stores the information; and a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel. A method for a receiving/transmitting unit of a wireless network for facilitating noise and interference measurements on an air interface is described. Information relating to a time-varying layout of a silent resource element (RE) grid is obtained and a presence of a silent RE grid is taken into account in the reception of a control or a data channel.
