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: Aspects describe communicating grant information in a multicarrier wireless communication system. The grant in-formation can be transmitted to mobile devices that have single carrier capability and/or mobile devices that have multicarrier ca-pability. Grant information can be sent in a legacy control region and/or a non-legacy control region.

Abstract: Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

Abstract: A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a pairing is determined between one or more uplink carriers and one or more downlink carriers. The one or more uplink carriers and the one or more downlink carriers include at least three carriers. On which carrier to exchange control information on one or more of the carriers is based on the pairing or an anchor carrier designation.

Abstract: Controlling transmission energy in a variable rate communication system that gates out portions of a frame in a predetermined and predicable fashion. In particular, the present invention describes a method and apparatus which identifies closed loop power control commands that have been generated erroneously based on portions of a frame that have been gated. The identified power control commands are ignored. In an alternative embodiment, if identification of the erroneous power control commands occurs after response measures have been taken, the transmitting station responds by setting the transmission energy back to the state it would have been in had the erroneous power control commands been identified prior to the response.

Abstract: Un procedimiento para gestionar recursos de un enlace de comunicación desde una estación móvil hasta una estación base en un sistema de comunicación, comprendiendo el procedimiento, en la estación móvil: seleccionar un tamaño de carga útil de un paquete de datos para transmisión sobre dicho enlace de comunicación; recibir un valor de potencia de transmisión de amplificación desde una estación base que indica una cantidad de diferencia de nivel de potencia entre un nivel de potencia amplificado y un nivel de potencia estándar para transmisión de dicho paquete de datos sobre dicho enlace de comunicación; seleccionar o bien dicho nivel de potencia amplificado o bien dicho nivel de potencia estándar basándose en un requisito de latencia de transmisión de dicho paquete de datos; transmitir dicho paquete de datos a dicho tamaño de carga útil y a dicho nivel de potencia seleccionado desde dicha estación móvil hasta dicha estación base sobre dicho enlace de comunicación.
