摘要： Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

摘要： Embodiments disclosed herein relate to a new set of radio link protocols (RLPs) configured to provide for efficient data transmission in a multi-link communication system. In an embodiment, an upper-layer packet is segmented into link-layer packets to be transmitted over a plurality of communication links, each including a first sequence number in accordance with a predetermined order. A second sequence number is further added to each link-layer packet to be transmitted for the first time. The second sequence number is configured to be in a sequence space associated with a particular communication link, and may be used for detection of missing packets.

摘要： A high data rate system capable of inter-frequency handoffs with little or no interruption in data service. The access network sends data from the first sector to the access terminal at the first frequency. The access terminal measures a parameter of a signal received at the access terminal from the second sector at the second frequency, wherein a pre-active set of the access terminal includes the second sector, and wherein an active set of the access terminal consists of one or more sectors operating in the first frequency. The access terminal then sends a data source control message corresponding to the second sector to the access network, after which the access terminal switches the pre-active set and the active set.
