Abstract:
A method and user equipment in a carrier frequency to perform contention based random access. The method includes receiving an indication from a network entity whether a cell in the carrier frequency supports a 2-step random access procedure. When the 2-step random access procedure is supported in the cell, a random access procedure is selected between the 2-step random access procedure and a 4-step random access procedure, wherein each of the 2-step random access procedure and the 4-step random access procedure includes one or more preambles, which are configured in the cell to be associated with one of the 2-step random access procedure or the 4-step random access procedures. A preamble is randomly selected and transmitted from the one or more preambles which are associated with the selected random access procedure, wherein the 2-step random access procedure includes a physical random access channel carrying preamble and a physical random access channel carrying data, and the 4-step random access procedure includes the physical random access channel carrying preamble, and wherein a time-frequency resource for the physical random access channel carrying data in the 2-step random access procedure is determined, based on the transmitted preamble. The physical random access channel carrying data is transmitted including a demodulation reference signal and one or more data symbols on the determined time-frequency resource.

Claim (Index 16):
The method in accordance with  claim 15 , wherein the valid user equipment identity is a cell-radio network temporary identifier, and the user equipment specific search space within which the random access response message is transmitted comprises user equipment specific physical downlink control channels, where appended cyclic redundancy check bits are scrambled by the cell-radio network temporary identifier.
