Claim Text:
1. A method for random access by a mobile station in a wireless network, the method comprising: receiving, from a base station, a spatial direction of at least one receive beam of the base station and configuration information of at least one transmit beam including a number of repetition of the random access signal, a maximum number of transmit beams that are formed by steering at each radio frequency (RF) chain, and timing information to transmit a random access signal, wherein the timing information includes a duration of each transmit beam or a duration of each transmit beam for one repetition associated with the random access signal to be transmitted to the base station over the at least one transmit beam; configuring at least one transmit beam for a transmission of the random access signal based on the configuration information and the spatial direction of the at least one receive beam; wherein the at least one transmit beam is selected in accordance with a beam width and a signal strength of the at least one transmit beam; and transmitting the random access signal to the base station on the at least one transmit beam that is configured in accordance with the receive beam configuration information and the spatial direction of the at least one receive beam received from the base station.
