Abstract
Systems and methods are disclosed herein that relate to determining a coverage scenario of a wireless device and determining an amount of resources to be used by the wireless device for transmission of a random access signal based on the coverage scenario of the wireless device. In some embodiments, a method of operation of a wireless device for random access to a cellular communications network comprises determining a number of resources needed for the wireless device to successfully decode an information block received from a radio access node. The method further comprises determining at least one of: a code rate and a transmit power used for transmission of the information block by the radio access node. The method further comprises determining an amount of resources to be used by the wireless device when transmitting a random access signal for a random access procedure based on the aforementioned information.
