Method of processing in random access procedure, system and apparatus thereof

A method of processing in random access procedure, wherein, comprising the following steps:

• when a Preamble transmitted by a random access node is detected by a base station, the base station calculating TA according to the Preamble detected by the base station itself and transmitting the TA to the random access node;
• the base station receiving random access detection information reported from a transparent relay station and selecting a service node for the random access node;
• and
• the base station receiving an uplink signaling transmitted by the random access node after an uplink timing advance is adjusted by the random access node according to the TA calculated by the base station, and notifying the random access node of an access condition through a contention resolution message according to the selected service node, and the random access node performing an access procedure based on the access condition.

A method of processing in random access procedure, wherein, comprising the following steps:

• a random access node transmitting a Preamble to a base station;
• the random access node receiving the TA calculated by the base station according to the Preamble detected by the base station itself, and adjusting an uplink timing advance according to the TA calculated by the base station;
• the random access node transmitting uplink signaling to the base station;
• and
• the random access node receiving contention resolution message transmitted by the base station, if the contention resolution message carries TA calculated by a transparent relay station, the random access node adjusting the uplink timing advance according to the TA calculated by the transparent relay station.
