Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
