Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. Coupled load information is exchanged between base stations allowing a base station to determine an appropriate allocation of reverse link channel resources to mobile stations served by the base station. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

Abstract: A method for managing a point-to-point call initiated (702) between a wireless mobile station (114, 400) and a remote party while the mobile is receiving broadcast content via one or more multi-user forward-link broadcast channels (508). The mobile station notifies (704) the network (110) of preferences as to prescribed categories of operating conditions, such as whether to continue receiving the broadcast content, and election between the point-to-point call and the broadcast content should network resources be unable to conduct the point-to-point call and broadcast content concurrently. In accordance with the preferences, communications are conducted (706) in one of the following operating modes: (1) conducting the point-to-point call and discontinuing reception of the broadcast, (2) conducting the point-to-point call and continuing reception of the broadcast, (3) aborting completion of the point-to-point call and continuing reception of the broadcast.

Abstract: Techniques for selectively combining multiple transmissions to recover a message comprised of multiple frames. Initially, each transmission is separately processed to recover the message. If the message cannot be recovered error-free from any single transmission, then portions of multiple transmissions are selectively combined to recover the message. Erased frames in a message recovered from a primary transmission (e.g., the one with the best pilot E c /I 0 ) and good frames from other transmissions are determined (e.g., based on the frame-level CRC). One or more combined messages are then formed, each including a different set of good frames substituting for the erased frames. If a good frame cannot be derived from any single transmission for a given erased frame, then symbols from multiple transmissions may be combined to derive the good frame. Each combined message is checked (e.g., based on the message-level CRC) to determine whether it is good or erased.

Abstract translation: 用于选择性地组合多个传输以恢复由多个帧组成的消息的技术。 最初，每个传输被单独处理以恢复消息。 如果消息无法从任何单个传输中无错误地恢复，则选择性地组合多个传输的部分以恢复消息。 例如，基于帧级CRC确定从主传输恢复的消息中的已擦除帧，例如具有最佳导频Ec / I0的帧和来自其他传输的良好帧。 然后形成一个或多个组合消息，每个组合消息包括替代已擦除帧的不同组的好帧。 如果对于给定的擦除帧不能从任何单个传输导出好的帧，则可以组合来自多个传输的符号以导出良好的帧。 检查每个组合的消息，例如，基于消息级CRC来确定它是否良好或被擦除。

Abstract: 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.

Abstract: A method and system for a handoff in a broadcast communication system is disclosed. A subscriber assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. To streamline the autonomous handoff decision process, several distinct sets of pilot identifiers and rules for transitioning among the sets are defined. To fully integrate broadcast services with the services provided by the cellular telephone systems in a subscriber environment, a methods for various handoff scenarios are analyzed.

Abstract: To enable point-to-multipoint communication services in an existing cellular communication system infrastructure, each member subscriber station, i.e., a subscriber station participating in such a service, is receiving a forward link shared channel, and in certain embodiments additionally a forward link dedicated channel. Because transmission on the forward link channels from neighboring sectors presents interference to the transmission from the sector serving the subscriber station, it is desirable to control the forward link channel transmission power to the minimum acceptable power. Additionally, a transmission form each member subscriber station on a reverse link channel presents interference to other subscriber stations. Therefore, it is desirable to control the reverse link channel transmission to the minimum signal level. Consequently, a method and apparatus for a per control that enables point-to-multipoint services in an existing infrastructure of a wireless cellular telephone system is disclosed.
