    Abstract: In a method for packet data transmission from at least one Access Point to an Access Terminal, data request messages are received from a plurality of Access Terminals. A transmission of data from the Access Terminal having the highest ratio of requested data rate to average served rate is scheduled, and an Access Point transmits data at a randomly varying transmit power, or at a transmit power in synchronism with neighbouring Access Points, in accordance with the data request message.

    Abstract: A method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system. The method includes when the pilot signal is transmitted by the mobile station that is power controlled to a target receive level, the traffic channel power level is increased relative to the pilot channel to improve receiver performance. An improved feature is that the received pilot received at the base station stays the same while the receiver receives extra energy in the redundant traffic symbols received to enhance the probability of correctly decoding the received frame. The base station detects the absence of the mobile station transmitted signal from the frequency of interest. If the base station is aware of the starting time and duration of the absence, it can focus its detection during this predetermined time period. The performance can be improved if the absence of the signal is spread across two frames at the frame boundary.

    Abstract: In a cellular telephone system a system for directing communications between a mobile user and cell-sites as a mobile user changes cell-site service areas. The mobile user includes an apparatus for, while in communication with another system user via one cell-site, determining a transition of the mobile user from the cell-site service area to the service area of another cell-site. The system includes circuitry responsive to the indication for coupling communications between the mobile user and the other system user via the new cell-site while the mobile user also remains in communication with the system user via the first cell-site. The system further includes apparatus responsive to the coupling of the communications between the mobile user and the other system user via the new cell-site for terminating the communications between the mobile user and another system user via cell-site with communications continuing between the mobile user and the system user via the new cell-site.

    Abstract: The present invention is a method and apparatus for integrating a personal communication system with a cable television plant. A set of radio antenna devices (RAD) are connected to the cable plant. The RADs provide frequency conversion and power control of signal received from the cable plant for wireless transmission to the remote units. The RADs also provide power control and frequency conversion of wireless signals received from the remote units for transmission by the RADs onto the cable plant. In addition to the functions of standard base stations and centralized controller, the CATV base station must also compensate for gain variations in the cable plant. The downstream power control is regulated by a RAD reference signal which can be hidden within the CDMA signal for maximum efficiency. The upstream power control is regulated by an upstream gain reference signal which is individually transmitted by each RAD on the upstream link. The architecture of the present invention lends itself to a great deal of flexibility. Each RAD can operate as either an element of a distributed antenna or a base station sector unto itself. The function of each RAD as distributed antenna or as sector can be remotely programmed from the headend processor. Thus the capacity density of the system can be changed to accommodate the changing traffic density. The flexibility also is important at system deployment. When the system is deploy, the entire system may feed only one sector at the base station thus reducing the start-up cost of implementing a system. As system traffic increases, more resources can simply be added at the headend to provide more capacity.
