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.
摘要翻译：描述了在广播服务通信系统中利用外部解码器的方法和系统。要发送的信息被提供给多个发送缓冲器的系统部分，并且由通信地耦合到发送缓冲器的外部解码器编码。所产生的冗余比特被提供给每个发送缓冲器的奇偶校验部分。发送缓冲器的内容被内部解码器复用和编码，以通过增加冗余来改善保护。接收站通过反向处理恢复发送的信息。由于解码复杂度取决于发射缓冲器的系统部分的大小，系统部分大小与发射缓冲器数量之间的合理折中产生降低的解码复杂度。

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： Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

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.

摘要： Embodiments described herein relate to connected-state radio session transfer in wireless communications. A source access network controller may lock a source radio session associated with an access terminal (e.g., in response to detecting a handoff condition associated with the access terminal), where the source access network controller may be in communication with a data network. The source access network controller may also instruct a target access network controller to create a target radio session corresponding with the source radio session, and to establish a communication route between the data network and the access network via the target ANC. The source access network controller may then freeze a state associated with the source radio session and transmits the frozen state to the target access network controller. The target access network controller may subsequently unfreeze the received state and further unlock the radio session, hence resuming control of the access terminal.
