摘要： The invention is directed to a method for receiving a feedback for at least a multicast broadcast service flow transmitting to a plurality of subscriber stations. The method comprises steps of assigning a plurality of code division multiple access (CDMA) codes to a feedback corresponding to the multicast broadcast service flow and then performing an allocation process for allocating a feedback channel for the subscriber stations. Thereafter, an announcement process is performed to announce a multiple feedback condition, the CDMA codes and the feedback channel to the subscriber stations. A channel monitoring process is performed for receiving a negative-acknowledgment (NACK)-based feedback sending from one of the subscriber stations unsatisfied with the multiple feedback condition and the NACK-based feedback is in a form of one of CDMA codes corresponding to the multicast broadcast service flow and is transmitted through the feedback channel.

摘要： The present invention relates to a scheduling unit in a wireless communication system. For sequentially receiving a plurality of Protocol Data Units (PDUs) in a plurality of communication sessions, accumulate and schedule the plurality of PDUs during a predetermined time frame, and transmit the PDUs based on a maximum power-strength of the wireless communication system. The scheduling unit comprises a time-based scheduler and a power-based scheduler. When the power-based scheduler schedules the PDUs, if the total sum of the required power of the PDUs exceeds the maximum power-strength of the wireless communication system, the power-based scheduler sends back to the time-based scheduler the PDUs whose power amounts to the exceeding of the maximum power-strength of the wireless communication system according to the corresponding priority values of the PDUs, so that the wireless communication system transmits all at a time the remaining PDUs whose total power remains within the maximum power-strength.

After that, a relay start confirmation procedure for the requesting UE and the relay UE is executed. Finally, a relay transmission procedure for the requesting UE, the relay UE, and the base station is performed, wherein the requesting UE sends the message to the base station via the relay UE. According to the invention, high data rate transmission can be achieved even if the requesting UE is distant from the base station, and thus communication quality can be improved, with a reduced cost.

摘要： Methods for multi-user detection in a CDMA-based channel for use in a base station receiver are provided. Signals, each including a CDMA code, are received. Correlation operations are performed on CDMA codes of received signals respectively to obtain corresponding first correlation values. CDMA codes are divided into first and second code groups according to a threshold and corresponding first correlation values. An interference cancellation procedure is performed on received signals to remove signals corresponding to first code group therefrom and to obtain a removed signal. Correlation operations are performed on CDMA codes of removed signal to obtain corresponding second correlation values. Each first correlation value is subtracted from a corresponding second correlation value and compared with a threshold to generate a comparison result. Whether CDMA codes within first code group are correct are determined according to comparison results, wherein the threshold is dynamically adjusted according to comparison results.

摘要： This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.
