Abstract
Official abstract text for this publication.
Embodiments of the present disclosure provide methods and apparatus for configuring additional CPICHs, e.g. third CPICH, fourth CPICH, etc., to support MIMO transmissions of rank three or higher. The additional CPICHs may be configured with two or more power levels. A radio network controller (RNC) sends configuration information for the additional CPICHs to a serving base station in a cell to configure the additional CPICHs. The additional CPICHs can be configured to have a fixed power level, or multiple power levels. When the additional CPICHs are configured with multiple power levels, the base station can select the appropriate power level for each CPICH in dependence on current scheduling decisions in order to reduce inference.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, implemented by a radio network controller in a wireless communication network, of configuring additional pilot channels in a cell having primary and secondary pilot channels to support multiple-input, multiple-output (MIMO) transmissions of rank three or higher, the method comprising: sending a configuration message to a serving base station in a cell having one or more pilot channels configured, said configuration message including configuration i…
