Abstract: Separate power control for the forward voice channel and forward data channel is provided without using additional bandwidth or decreasing the amount of pilot signal provided from the mobile to the base station. Alternating voice and data power control commands or information are transmitted in the pilot channel by a mobile to a base station. In one embodiment, the power control portion of a first pilot channel segment is used to provide power control for the forward voice channel and then in the following pilot channel segment, the power control portion is used to provide power control for the forward data channel. In other embodiments, other than a 50/50 mix between voice and data power control is provided in the mobile's pilot channel. For example, forward voice channel power control commands may be transmitted two or more times for each transmission of forward data channel power control commands.

Abstract: The invention is a repeater for a telecommunications transmission system such as a CDMA wireless system. The repeater reduces leakage by means of a feedback signal (on 30,31,32,33) whose amplitude and phase are adjusted (in 31) in response to the amplitude and phase of a sampled input signal (from 35) when a switch (24) turns off the normal output of the repeater for a short period of time. In one embodiment, a pilot signal (from 40) is transmitted during this time period so that the sampled input is the leakage signal. In another embodiment, the sampled input is the normal transmission signal received during the time period.

Abstract: A high priority and/or emergency overload access control system treats a wireless unit as a higher priority wireless unit when the wireless unit is attempting to access a wireless communications system with a high priority call, such as an emergency call. For example, the overload access control system can recognize if the wireless unit is attempting to initiate a call to an emergency number. If so, the wireless unit can perform a persistence test as an emergency class (e.g. overload class 10-15) wireless unit in attempting to access the wireless communications system. Thus, the wireless unit will experience an increased probability of passing the persistence test and thereby reducing the persistence delay in attempting to access the wireless communications system with the emergency call.

Abstract: A method that changes the power level of a set of forward-link signals, independent of the individual power control of each of the forward-link signals in the set, responsive to a comparison of the signal set's power level and a threshold power level (P th ). The threshold power level (P th) is based on the base station's (200, 400) amplifier's (15 0) maximum threshold power level. The power level of the set is changed by scaling it by a scalin g factor. The total power level (P[n-1]) of the set is obtained during a current frame, and then the scaling factor (g[n]) that will be used in the subsequent frame is determined. The scaling factor (g[n]) is preferably based on the total power level (P[n-1]) of the set for the curren t frame, a scaling factor (g[n-1]) used during the current frame, and a threshold power level ( P th). The amount by which the total power level exceeds the amplifier's maximum continuous power level is the overload amount. The scaling factor is selected so that for each frame the overload amount is reduced by a percentage. For example, the overload amount can be reduced by 3% for the current frame, then the percentage may be changed for a subsequent frame based on th e scaling factor of the current time period and the overload amount of the subsequent time perio d. The set caninclude all of the signals amplified by the base station's amplif ier (150); alternatively, the set can include fewer than all the signals generated by the base station. For example, the set can include a plurality of the traffic signals, or a plurality of the traffic signals and one or more of the control signals. When the base station includes a plurality of amplifier s, each for amplifying a set of signals, the above process can be performed for each of the sets of signals.
