18 Claims

1. A method performed by a user equipment, the method comprising:

in response to being triggered by one of a plurality of random access events, determining random access transmission parameters to be used for transmitting a random access message to a base station,

wherein the random access transmission parameters include a transmit power value which is determined based on the random access event and on random access configuration information,

transmitting the random access message to the base station using the determined transmit power value,

receiving a first part of the random access configuration information for a first random access event within minimum system information broadcast by the base station, and

receiving a second part of the random access configuration information for a second random access event in a dedicated message transmitted from the base station and addressed to the user equipment,

wherein the second part of the random access configuration information is associated with a prioritized random access.
