Abstract: A wireless device, a base station, a random access method and a preamble configuration method are provided. The mobile communication system defines a plurality of preambles, a plurality of low priority preamble sets, and a high priority preamble set. The low priority preamble sets have a strict partial order relationship therebetween. The high priority preamble set and the highest-order low priority preamble set are independent from each other. When requiring random access from a base station, the wireless device randomly selects a preamble from the low priority preamble sets to transmit a random access request message to the base station by using the selected preamble. When the request for random access fails, the wireless device with low priority randomly reselects a preamble from the higher-order low priority preamble set, and the wireless device with high priority randomly reselects a preamble from the high priority preamble set.

Abstract: A user equipment (UE), a mobile hotspot equipment, a backhaul device and a method for establishing a path loss model database are provided. The UE receives a wireless signal from a first surrounding mobile hotspot equipment, and measures the wireless signal during a time interval so as to generate received signal information corresponding to the wireless signal. Thereafter, the UE transmits a measurement response message that includes an identity of the first surrounding mobile hotspot equipment and the received signal information to the backhaul device via the mobile hotspot equipment. Accordingly, the backhaul device establishes a path loss model according to the received signal information and stores the path loss model into a path loss model database.
