    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A base station generates per-cell ACK/NACK responses rather than per-sector ACK/NACK responses. For a given mobile station signal received in softer handoff at two of the base station's sectors, the base station generates an ACK response if at least one of the soft handoff sectors correctly receives the signal, and otherwise generates a NACK response. Alternatively, the base station can combine the softer handoff signals and generate ACK/NACK responses based on whether the combined signal is correctly received. Since only one set of ACK/NACK responses are generated for all of the softer handoff sectors, the base station can use the forward link in just one softer handoff sector to send the ACK/NACK responses to the mobile station, consuming fewer forward link transmit resources at the base station. Or, the base station can send the same ACK/NACK responses from two or more softer handoff sectors, thus allowing diversity combining of the ACK/NACK responses at the mobile station.

    摘要: A method of scheduling wireless packet data traffic on a downlink packet data channel takes advantage of early decoding opportunities to decode the channel feedback reports before receipt of the mandated Lth repetition. The early-decoded channel feedback reports are promptly used in making scheduling decisions. Mobile stations are required to repeat transmissions of channel quality reports at least L times. The base station receives channel quality information report CFN from a first mobile station one or more times, but less than L times; and, prior to reception of the Lth repetition of CFN, successfully decodes CFN to form a first decoded report. Packet data transmissions on the downlink packet data traffic channel are scheduled based on CFN. A corresponding apparatus is also described.

    摘要: A wireless communication network manages variable data rate communication channels using both short-term data rate adaptation and longer-term resource allocation adjustment. For example, an exemplary base station system may track the actual transmit power being used to transmit a given communication channel on a per frame basis, or faster, and use that tracked value to infer changing channel conditions, e.g., for a given current data rate, higher power indicates poorer channel conditions and lower power indicates better channel conditions. Additionally, or alternatively, channel quality information reported by a receiving mobile station can be used. Regardless, relatively fast data rate changes can be made responsive to monitoring the channel conditions, while retaining the communication resource allocation for the channel. Over the longer term, however, the allocation itself can be changed, e.g., increased or decreased, depending on whether the channel is being efficiently utilized.

    摘要: In a wireless communication network providing voice and data services, one or more entities in the network, such as a base station controller and/or radio base station, can be configured to reduce data services overhead responsive to detecting a congestion condition, thereby increasing the availability of one or more network resources for voice services. In one or more exemplary embodiments, one or more current data services users are targeted for modification of their ongoing data services to effect the reduction in data services overhead. Modifications can include, but are not limited to, any one or more of the following: forward or reverse link data rate reductions, and shifting of forward or reverse link traffic from dedicated user channels to shared user channels. Targeting of users for service modification can be based on reported channel quality information. For example, users reporting poor radio conditions can be targeted first for service modifications.
