Abstract

See full text

The disclosure relates to connection setup between a wireless device and a mobile communication network using random access, and more specifically to dynamic random access resource configuration and selection. The disclosure provides for a method in a wireless device, of selecting random access resources for performing a random access procedure to a wireless network. The method comprises the step receiving information from a radio network node comprised in a cell of the wireless network, wherein the received information indicates at least a first and a second random access resource having different resource sizes. The method further comprises selecting one of said at least first and a second random access resources based on an expected uplink power received by the radio network node and transmitting a random access message to said wireless network using the selected resource. The disclosure further relates to methods for providing random access resources, as well as to a wireless device, and to radio network nodes of a wireless network.
