Example Embodiment
[0022] The embodiment of the invention discloses a method for enhancing random access. When the Node B controls the enhanced random access initiated by the UE, the UE accesses through the power climbing process, which makes the initial transmission power of the UE in uplink transmission more accurate, which is conducive to the accuracy of uplink transmission information and the completion of uplink synchronization as soon as possible. The method for enhancing random access of the present invention will be described in detail below with reference to the accompanying drawings.
[0023] figure 1 It is a schematic flowchart of an embodiment of an enhanced random access method of the present invention. Such as figure 1 As shown, the method includes:
[0024] 101. The Node B sends an HS-SCCH order.
[0025] In this step, the HS-SCCH order sent by the Node B carries the user equipment identifier UEID and E-DCH resource identity (E-DCH resource number) or UE ID and access preamble sign...
