Abstract:
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.
Abstract:
A system for scheduling packets to be transmitted is provided. The system includes a soft delay bound calculator module and a frame determination module. The soft delay bound calculator module calculates a soft delay bound for a non-real-time packet based on a packet size of the non-real-time packet and a minimum reserved traffic rate of a channel. The frame determination module determines whether a real-time packet must be transmitted at a current frame according to a delay bound, a transmission time, and a possible retransmission time thereof, and whether a non-real-time packet must be transmitted at a current frame according to a soft delay bound, a transmission time, and a possible retransmission time thereof. Thus, it is possible to improve the performance of the system while keeping the QoS thereof in a mixed service environment.

The first-type wireless device conforms to the first-type communication standard and the second-type wireless device conforms to the second-type communication standard.
Abstract:
A gain adjustment apparatus, a gain adjustment method, and a tangible machine-readable medium thereof for a multiple input multiple output (MIMO) wireless communication system are provided. The MIMO wireless communication system comprises source antennas, destination antennas, relay stations (RSs) and a relay transmission power limit value. The gain adjustment method comprises the following steps: adjusting the gain of one single RS according to a gain calculation; multiplying the gains of other relay stations by a scaling value for adjustment. According to aforesaid method, the present invention can increase the system capacity of the MIMO wireless communication system.
Abstract:
The present invention relates to an interference reduction apparatus, an interference reduction method and a computer storage medium. The interference reduction apparatus can estimates the channel of the cells comprehensively to obtain the combination information and the interference power level information. The combination information and the interference power level information is used to combine at least one precoding matrix of he codebook with each other to generate a combined precoding matrix which acts as the strongest signal power from the interference reduction apparatus and the weakest interference from the neighboring cells.
Abstract:
A communication apparatus, a communication method, and a computer program product for a wireless communication system are provided. The communication apparatus comprises a receive module, a process module, and a transmit module. The receive module is configured to receive a first request message transmitted from a first mobile apparatus with at least one first sequence and to receive a second request message transmitted from a second mobile apparatus with at least one second sequence. The processing module is configured to determine whether the at least one first sequence is the same as the at least one second sequence. The transmission module is configured to transmit a response message according to the determination result. Finally, the first and second mobile apparatuses determine whether to transmit a first and second data according to the response message, respectively.
Abstract:
