  • Patent number: 8200285
    Abstract: A method, apparatus, system, and computer program embodied on a computer readable medium is provided to define new messages to be transmitted over a broadcast channel to better support uncoordinated base station deployment in a local area environment. In this context, uncoordinated local base station deployment refers to cases where new base stations are placed, and activated, without any detailed a priori network planning and considerations for placement of already active base stations in the area.
    Type: Grant

  • Publication number: 20090135786
    Abstract: A set of permissible parameter pairs with the parameters being a number of code channels and an associated spreading factor is determined according to at least one first selection criterion. Then a parameter pair from the set of permissible parameter pairs for the CDMA transmission is selected according to at least one second selection criterion. In this selection process, the spreading factor is used as a second selection criterion with a higher value being preferred over a lower value if both spreading factors are below or equal to a threshold spreading factor value. This accounts for the fact that in a certain regime low spreading factor involve a prohibitively high processing load and lead to increase inter symbol interference.
