Abstract  Abstract

A method in a wireless device for performing a random access to a network node. the method comprising: receiving a set of downlink beam specific reference signal BRS from a network node and based on the received signal power of each BRS to determine the preference of the BRS. the method further comprises: based on the preference of the BRS selecting random access resources to be used for sending random access attempt to the network node and when sending random access attempt to the network node using the selected random access resource whereby the selected random access resource to the network node indicates that the wireless device preferably downlink beam to be used for downlink transmission.

A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals BRS from the network node and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting based on the preferred BRS a random-access resource to be used for transmitting a random-access attempt to the network node as well as using the selected random-access resource when transmitting a random-access attempt to the network node whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.
