Abstract: A call recovery method uses a multiple access forward call recovery channel to perform simultaneous rescues for multiple mobile stations. Rescue messages, such as handoff direction messages, for different mobile stations are multiplexed onto the call recovery channel for transmission to mobile stations in need of rescue.

Abstract: In a multicarrier CDMA system, a data stream is divided into two or more substreams and each substream is assigned to a different carrier. An RLP context is created for each carrier and the substreams are transmitted within a corresponding RLP context over a designated carrier. If a carrier is lost or dropped, the corresponding RLP context can persist after loss of the carrier and retransmitted packets tunneled to a different carrier.
Abstract translation: 在多载波CDMA系统中，数据流被分成两个或多个子流，每个子流被分配给不同的载波。 为每个载波创建RLP上下文，并且在对应的RLP上下文中在指定的载波上发送子流。 如果运营商丢失或丢弃，则相应的RLP上下文可能在丢失运营商和重新发送的分组隧道传输到不同的运营商后可以持续。

Abstract: A communication station employs discontinuous transmission of channel quality feedback to reduce channel quality feedback transmitted over overhead channels. Prior to transmitting channel quality information to a remote station, the communication station compares the channel quality feedback to predetermined qualification criteria. If the qualification criteria are not met, the channel quality feedback is not transmitted. The method may be implemented by a mobile station to reduce channel quality feedback sent to a base station over a reverse link overhead channel.

Abstract: A base station in a wireless communication network multi-codes a shared packet data channel using a continually changing set of spreading codes, and dynamically updates the transmission frequency of messages identifying the spreading codes to be used for that multi-coding based on tracking the net gain in data throughput for the shared channel that is obtained by transmitting such messages. In a 1xEV-DV network context, for example, a Walsh code in the defined Walsh code space that is not contiguous with the Walsh codes currently allocated to multi-coding the 1xEV-DV Forward Packet Data Channel (F-PDCH) generally remains unavailable for such use until an updated Walsh Mask Broadcast (WMB) message is transmitted to the mobile stations being served on the F-PDCH. The base station thus is configured to determine the frequency at which to send such messages and thereby make the unavailable codes available for multi-coding use.

Abstract: A method and apparatus provide for setting the initial transmit power of secondary reverse link carriers used by mobile stations in conjunction with primary reverse link carriers. In one or more embodiments, a mobile station sets the initial transmit power of a secondary reverse link carrier relative to the transmit power of the primary reverse link carrier as a function of initialization transmit power information transmitted to the mobile station, which directly or indirectly considers reverse link loading information. Additional considerations may include differences in active sets associated with the primary and secondary reverse link carriers and/or sector switching activity of the mobile station.

Abstract: Una red de acceso por radio (30) que incluye múltiples sectores (14) que comprende: dos o más transmisores (54) de sector que sirven a respectivos sectores para transmitir datos a estaciones de telefonía móvil; una pluralidad de antenas (56), estando cada antena asignada a un transmisor de sector respectivo; y un procesador (60) de gestión de antenas que controla las asignaciones de antenas de sector y que está operativo para reasignar dinámicamente una antena de sector asociada con un transmisor de sector en un primer sector a un transmisor de sector en un segundo sector.
