Abstract

A method for use in a first node in a wireless access communication system (). According to the method, the first node controls traffic to and from users, UEs, within a certain area in the system, a cell, and the first node is equipped with a plurality of transmit antennas. The first node can employ a variety of multi antenna transmit modes for downlink transmissions, i.e. transmissions to the UEs, and the first node can carry out a so called Random Access (RA) procedure with UEs which do not have a dedicated uplink resource, i.e. a resource to the eNodeB. According to the method, one and the same downlink multi antenna transmit mode is used by the first node during the RA procedure.
