摘要： A memory management method and a memory architecture for transmitting ultra-wideband (UWB) prioritized channel access (PCA) frames are provided. The method comprises the steps of assigning a pre-load queue to each of a plurality of access categories for storing UWB PCA frames to be transmitted, and, when one of the access categories gains transmission opportunity (TXOP), assigning a common area queue to that access category for storing UWB PCA frames to be transmitted. Moreover, when a UWB PCA frame in one of the pre-load queues reaches a predetermined size, the access category corresponding to the pre-load queue starts its backoff state machine in order to gain the TXOP.

摘要： A multi-linguistic wireless spread spectrum narration service system includes a speech database, a plurality of basestation units, and at least one mobile unit. The speech database is stored with multi-linguistic narration service speech messages. The plurality of basestation units are arranged at each exhibition section of an exhibition field. Each basestation unit controller captures narration service speech messages from the speech database and a wireless communication is performed. The mobile unit controller is provided to be worn by a visitor. The mobile unit detects the wireless signals of a specific basestation unit. Thus, a synchronous or asynchronous connection is built through the spread spectrum radio frequency processing and baseband processing module. Therefore, the narration service speech message from the basestation unit is received.

The wireless communication system comprises a BS and at least one RS. The BS divides the channel descriptor into a common channel descriptor and at least one particular channel descriptor. Then the BS broadcasts/multicasts the common channel descriptor to the at least one RS and transmits the at least one particular channel descriptor to the same. The at least one RS combines the common channel descriptor and the at least one particular channel descriptor to generate the channel descriptor.

摘要： 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.
