摘要:
A wireless apparatus, a base station and uplink contention methods thereof are provided. The wireless apparatus selects a preamble sequence and at least one resource block on an uplink shared channel (UL-SCH) according to a mapping rule. The wireless apparatus transmits an uplink signal with a preamble sequence on a random access channel (RACH) and a control message on the at least one resource on the UL-SCH to a base station. The base station detects the preamble sequence from the RACH, and retrieves the control message from the at least one resource block on the UL-SCH according to the mapping rule.

A mobile station (MS), a base station (BS), a transmission method and a computer storage medium thereof are provided. When the MS requests a bandwidth from the BS, it may generate a selected transmission sequence and a quick access message. The selected transmission sequence comprises pre-defined bit information (e.g., a flow identification, a size of the bandwidth or the like), and the quick access message comprises a station identification of the MS. The MS may transmit the transmission sequence and the quick access message to the BS in a frame so that the BS may allocate the bandwidth to the MS according to the size of the bandwidth, the station identification and the flow identification. Thereby, the amount of the control signals needed when the MS requests a bandwidth from the BS may be decreased.

The present invention relates to a resource allocation apparatus, subscriber station, resource allocation method, and non-transitory computer readable medium thereof. The resource allocation apparatus may know the unoccupied partition of the wireless network resource and allocate the unoccupied partition to the SS of the femtocell network. Thereby, the SS of the femtocell network will not occupy the same network resource of the macro BS or other femto SS, and interference of between femtocell and macrocell or other femtocell is reduced effectively.

A mobile station, a base station, a communication system and an abnormal power down reporting method thereof are provided. The communication system includes the mobile station and the base station. The mobile station is located within a wireless communication range of the base station. The mobile station transmits a notification message to the base station after detecting abnormal power down of the mobile station. The base station determines that abnormal power down occurred in the mobile station according to the notification message, and notifies a backhaul network to deregister the mobile station.
