摘要： A method for handover in a wireless communications network includes the step of communicating information between a target network node and a source network node to enable the source network node to identify and to distinguish types of failures prior to, during or after handover. The information may relate to: “Handover command not received” due to RLF prior to handover or Handover command failure experienced in the source cell; or “Handover failure” where “Handover command received” is followed by Access failure in the target cell. The method is applicable, for example, to networks in accordance with LTE.

摘要： A method for providing a static beam forming in a wireless communication system using an antenna arrangement of a base station which shapes at least one fixed beams, whereby the antenna arrangement covers at least two cells, each cell being covered by at least two beams. The at least two beams covering a cell use the same scrambling code and the same phase reference, whereby the base station autonomously decides which of the at least two fixed beams covering a cell should service a channel.
