摘要： A random access method, a parameter assignment method, a wireless communication device, and a base station using the same are provided. The random access method is adapted for the wireless communication device to perform a random access process with the base station, and includes following steps. The wireless communication device transmits a preamble code to the base station, obtains an indicator in a packet transmitted from the base station, and determines whether to obtain a first random access response and a second random access response according to the indicator. When the transmission of the preamble code by the wireless communication device encounters a collision and the indicator is set the wireless communication device performs a random access process by using the command in the first random access response. Otherwise, the wireless communication device performs the conventional process.

摘要： An apparatus is provided for relaying content between a macro base station and a femto base station of a femtocell whose geographic area of coverage is at least partially overlapped by a macrocell including the macro base station. As a user equipment, the apparatus may receive information, including a random access code, which has been coordinated between the macro base station and femto base station. The apparatus may prepare the random access code for transmission on a random access channel to the macro/femto base station in an instance in which the other of the macro/femto base station is serving the apparatus. The code serves to notify the macro/femto base station that the apparatus has been selected to relay content between the macro base station and femto base station. And consequently, the apparatus may also relay content between the macro base station and femto base station.
