摘要： A radio base station has at least two radio chains and a precoder for precoding information symbols by a precoding matrix for multi-antenna transmission to a number of user equipment terminals. Precoding matrix statistics representative of phase coherency between at least two radio chains is compiled based on feedback information representative of preferred precoding matrix from one or more user equipment terminals (S1). A relative phase error is then detected between radio chains based on the compiled precoding matrix statistics (S2). It is then possible to compensate or otherwise adjust for the detected relative phase error (S3) based on the compiled precoding matrix statistics.

摘要： A system, method, and base station antenna for improved coverage in a cellular mobile telephony network. Each cell in the network has an area defined by azimuth and range limits. In the system, a first cell and a second cell are essentially adjacent to each other in azimuth. A third cell has an azimuth limit that is essentially equal to the total azimuths of the first and second cells, and has a range coverage that is shorter than the ranges of the first or second cells. The base station antenna forms separate “conventional” beams for the first and second cells, and forms a “near cell” beam for the third cell.
