FIELD: information technology. ^ SUBSTANCE: invention discloses 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, UE, within a certain area in the system, a cell, and the first node is equipped with a plurality of transmit antennae. The first node can employ a variety of multi-antenna transmit modes for downlink transmissions, i.e. transmissions to the UE, and the first node can carry out a so called Random Access (RA) procedure with UE which do not have a dedicated uplink resource, i.e. a resource to the eNodeB. According to the method, the same downlink multi-antenna transmit mode is used by the first node during the RA procedure. ^ EFFECT: providing different multi-antenna transmit modes during random access procedure. ^ 25 cl, 6 dwg |
