Abstract: The invention discloses a method (400) for use in a first node (110) in a wireless access communication system (100). According to the method, the first node controls (405) traffic to and from users, UEs (120), within a certain area in the system, a cell, and the first node is equipped (410) with a plurality of transmit antennas (111,113). The first node can employ (415) a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry (420) out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.
