    摘要: A method of detecting DTX frames in frames received over a communication channel and a power control method are described, where radio link protocol (RLP) information received over the channel may be received, and one or more frames associated with the RLP information may be determined as an erasure or a DTX frame, based on the RLP information. Such determination may be incorporated into outer loop power control algorithms for adjusting a threshold related to a specified quality of service.

    摘要: A method of calculating a power threshold for a secondary communication channel capable of operating in DTX mode in forward or reverse links so that the communication channel is prevented from entering a deadlock state. Power threshold information for an associated primary channel and the secondary channel are used to update the established power threshold for the communication channel. The updated power threshold for the communication is thus calculated by combining previously established thresholds for the communication channel and associated primary channel with a current established threshold for the associated primary channel.

    摘要: A power control method for reverse links used in soft handoff mode between a mobile and base stations of a CDMA wireless communication network. Each of the base stations computes a setpoint based on the quality of received frames. The lowest setpoint value is then used as a threshold for inner loop operation causing at least one of the reverse links to convey information in compliance with a target FER set by the network.

    摘要: A base station in a soft handoff adjusts its transmit power level by a first amount if the base station is participating in a soft handoff and by a second amount if the base station is not participating in the soft handoff, i.e. in simplex mode. The first and second amounts are different. In one embodiment of the invention, the adjustment is performed by using a down-step size that is larger in magnitude than an up-step size when the base station is in soft handoff. The transmit power level is then adjusted by the smaller up and larger down step sizes when the base station receives an indication to adjust the transmit power level. The step sizes used when the base station is in simplex mode is larger than the up-step size and smaller than the down step size. In another embodiment, when the base station is in soft handoff, the adjustment is performed by adjusting the transmit power level by the same step size as used during simplex mode when the base station receives an indication to adjust the transmit power level and then reducing the result by a reduction amount. The order of these two steps can be reversed, and the transmit power level can be first reduced by the reduction amount and then adjusted by the same step sizes as used during simplex mode. The reduction amount has a magnitude greater than zero and smaller than the step size. The method of adjusting the base station transmit power level by different amounts based on whether the base station participating in a soft handoff can be used with the method of programming each base station in a soft handoff with a threshold power level to constrain the power transmitted by the base station on the forward link. When the threshold power level is a minimum-threshold power level, each base station maintains its transmit power level at or above the minimum-threshold power level. When the threshold power level is a maximum-threshold power level, each base station maintains its transmit power level at or below the maximum-threshold power level. The threshold power level can be either an adjustable or a fixed threshold power level.

    摘要: A method and system for predicting a signal power to interference metric for a communication channel in a coverage area of a phase sweep diversity communication system are provided. In the method, a signal power to interference metric for the communication channel is predicted based on a sweep frequency for transmissions in the coverage area. The signal power to interference metric predicted may be a carrier-to-interference ratio or a signal-to-noise plus interference ratio.

    摘要: A base station assembles a frame including information bits at a vocoding rate for downlink transmission over a traffic channel as channel bits at a channel rate. The base station places at least one rate-indicating bit at a beginning of the frame for indicating the vocoding rate. The mobile station evaluates the downlink transmission with consideration of the vocoding rate indicated by the at least one rate-indicating bit. The mobile station can determine the vocoding rate by decoding the beginning of the frame to permit power control in less than one frame duration from initial receipt of the frame at the mobile station.

    摘要: A method and system for controlling down link transmit power during a soft hand-off in a spread-spectrum wireless system supports independent power control of multiple forward channels to reduce fading. For a soft hand-off, a mobile switching center determines if a forward control channel is transmitted from different sectors of base stations than a forward data channel is. The base stations preferably adjust transmit powers of the forward channels grouped into different physical channels by receiving power control data over the allocated reverse power control channels to compensate for fading of the forward channels during a soft hand-off.

    摘要: A method and apparatus that permits base stations to adaptively set initial power levels in forward link traffic channels (i.e., base station to mobile unit) based on an interference measure, where the interference measure is the difference between the base station transmitted pilot EC/IO and the mobile unit received pilot EC/IO. The interference measure indicates how much interference is present from other base stations in the mobile unit's locale, mobile receiver noise and other similar sources. Call quality and system capacity are optimized since the initial power level is set in accordance with the interference environment. The method of the invention implements the adaptive setting by extracting the mobile unit received pilot EC/IO from the access message transmitted by the mobile unit. The interference measure is then determined and used by the base station to set the initial power level in the forward link traffic channel.
