RANDOM ACCESS PROCEDURE(S) FOR RADIO SYSTEM
First Claim
1. A user equipment comprising:
- receiver circuitry configured to receive from a base station apparatus configuration parameters for a random access procedure, wherein the configuration parameters include a set of random access preambles and physical random access channel (PRACH) resources reserved for a request of system information;
processor circuitry configured to select a random access preamble and PRACH resource from the set of random access preambles and the PRACH resources in a case of requesting the system information; and
transmitter circuitry configured to transmit the random access preamble using the PRACH resource.

Abstract
In one of its aspects the technology disclosed herein concerns a communications system comprising an access node (22) and a wireless terminal (26). The wireless terminal comprises receiver circuitry (40) and transmitter circuitry (44) as well as processor circuitry (40). The receiver circuitry (40) is configured receiver circuitry configured to receive from a base station apparatus configuration parameters for a random access procedure. The configuration parameters include a set of random access preambles and physical random access channel (PRACH) resources reserved for a request of system information. The processor circuitry (40) is configured to select a random access preamble and PRACH resource from the set of random access preambles and the PRACH resources in a case of requesting the system information. The transmitter circuitry (44) is configured to transmit the random access preamble using the PRACH resource.
