Antenna components of a cylindrical antenna array are adjusted, to dynamically share loads among sectors of a cell or between cells. The antenna components are adjusted based on beam configuration and/or orientation for example, depending upon a monitored load, to thereby vary antenna coverage areas to adjust for varying traffic densities. Antenna components are adjusted to accommodate load variations within a cell, and/or between cells.

A system and method have been developed wherein a cylindrical antenna array is configured and reconfigured in a wireless communication network. Position and signal information are continuously received from wireless mobile units and are used to determine reconfigurations of antenna components of the cylindrical antenna array to enhance performance of the system. As such, base station antennas are dynamically configured to minimize such things as interference and dropped calls, and to maximize their voice quality both within a cell, and among neighboring cells.

In a wireless communications system, a base station transmits power control signals (e. g. , the power control bits of a power control sub-channel) to a mobile using a forward-link channel that is decoupled from all other signals transmitted from that base station to that mobile. For example, the decoupled forward-link channel may be a common power control channel. The mobile then uses the power control signals received in the decoupled forward-link channel to control its power level for transmitting one or more reverse-link channels to the base station. The ability of base stations to use decoupled forward-link channels in order to transmit their power control signals to a mobile enables a mobile to operate with different active sets for the forward and reverse links. This enables forward-link data traffic to be implemented using a simplex mode, even when the mobile is operating in soft handoff in the reverse link. This in turn greatly reduces the reactivation time involved in transitioning a mobile from the suspended state to the active state, which is particularly desirable for bursty (i. e.

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.

The invention is a method for controlling power on multiple forward link communication channels by using multiple power control sub-channels, wherein each power control sub-channel is associated with a forward link communication channel to be power controlled. A fundamental power control sub-channel and a supplemental power control sub-channel are time multiplexed onto a reverse pilot channel. Transmitted over the fundamental power control sub-channel is a fundamental power control bit for indicating to a base station to increase or decrease its transmission power over a corresponding forward fundamental channel. Transmitted over the supplemental power control sub-channel is a supplemental power control bit for indicating to a base station to increase or decrease its transmission power over a corresponding forward supplemental channel. The pilot sub-channels are preferably separated by the fundamental and supplemental power control sub-channels for time diversity purposes.

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.

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.

A power control method of the invention may be applied to downlink power control, uplink power control, or both to support different quality of service levels for multiple channels per a mobile station. The power control method transmits control data between a base station and a multi-channel mobile station on a single communications channel or sub-channel to minimize or reduce overhead traffic from the control data.
