A method during a random access procedure and apparatus is provided, where a first downlink transmit antenna port is selected for transmission on random access channel resources associated with the first downlink transmit antenna port using a first preamble transmit power. A second downlink transmit antenna port is then selected, which is different from the first downlink transmit antenna port, when a random access response message is not received within a random access response reception time window. A preamble transmit power adjustment value is then determined, based upon one or more downlink transmit antenna port specific parameters received from the wireless communication network. A second preamble transmit power based on the determined preamble transmit power adjustment value and the first preamble transmit power is determined. A second preamble with the determined second preamble transmit power is then transmitted on a second subset of random access channel resources, which are associated with the second downlink transmit antenna port.
