Selection of transit mode during a random access procedure
Disclosed is 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 down link 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 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.
