Abstract: To enable point-to-multipoint communication services in an existing cellular communication system infrastructure, each member subscriber station, i.e., a subscriber station participating in such a service, is receiving a forward link shared channel, and in certain embodiments additionally a forward link dedicated channel. Because transmission on the forward link channels from neighboring sectors presents interference to the transmission from the sector serving the subscriber station, it is desirable to control the forward link channel transmission power to the minimum acceptable power. Additionally, a transmission form each member subscriber station on a reverse link channel presents interference to other subscriber stations. Therefore, it is desirable to control the reverse link channel transmission to the minimum signal level. Consequently, a method and apparatus for a power control that enables point-to-multipoint services in an existing infrastructure of a wireless cellular telephone system is disclosed.

Abstract: Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at R-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

Abstract: Systems and techniques for communications wherein a data packet is transmitted over at least one time slot from a transmission site, a value is computed from an initial value and information, the initial value being a function of the number of time slots of the data packet transmission, the value and the information is transmitted from the transmission site, the transmitted value and the information is received at a receiving site, the value from the received information is recalculated, and the number of time slots of the data packet transmission is determined from the calculated and recalculated values.

Abstract: A method for generating a higher rate channel using a set of N lower rate channels, the method comprises generating a set of N sinusoids having a corresponding set of N phase offsets with predetermined phase rotations; upconverting said set of N lower rate channels using said set of N sinusoids and phase offsets yielding a set of upconverted signals; summing said set of upconverted signals yielding a summed signal whereby the peak-to-average amplitude of said summed signal is reduced based on said phase rotations; and transmitting said summed signal. A corresponding system is also disclosed.

Abstract: A novel and improved method for implementing a high-transmission-rate over-the-air interface is described. A transmit system provides an in-phase channel set (90) and a quadrature-phase channel set (92). The in-phase channel set (90) is used to provide a complete set of orthogonal medium rate control and traffic channels. The quadrature-phase channel (92) set is used to provide a high-rate supplemental channel and an extended set of medium rate channels that are orthogonal to each other and the original medium rate channels. The high-rate supplemental channel is generated over a set of medium rate channels using a short channel code. The medium rate channel are generated using a set of long channel codes.
