1. A method performed by a wireless device, the method comprising:
selecting one of an occasion and resource unit to use for transmitting a payload within a slot that is the same as or immediately after a slot in which the wireless device transmits a random access preamble for random access to a wireless communication network, the one of the occasion and resource unit is selected based on one or more selection criteria, the one or more selection criteria include one or more of a type, purpose, and priority of an event that triggered the random access, the selecting comprising selecting one of an occasion and resource unit that starts one of:
less than or equal to a first threshold amount of time; and
more than a second threshold amount of time after an end of the transmission of the random access preamble, depending respectively on whether the priority is a first priority level or a second priority level, the first priority level being higher than the second priority level, the first threshold amount of time being one of the same as and different than the second threshold amount of time; and
transmitting the payload using the selected one of the occasion and the resource unit.
