Abstract: A drifting wireless transmit/receive unit (WTRU) has an associated drift radio network controller (D-RNC) 38 and an associated servicing radio network controller (S-RNC) 40. The D-RNC 38 sends a request message to the S-RNC 40 requesting measurements of the drifting WTRU. The S-RNC 40 receives the request message and sends an information message with the requested measurements to the D-RNC 38. The D-RNC 38 receives the information message.

Abstract: Un método y un sistema de comunicacion inalámbrica para controlar un portador de acceso de radio (RAB) de enlace ascendente mejorado (EU). El sistema de comunicacion inalámbrica incluye al menos una unidad inalámbrica de transmision/recepcion (WTRU), al menos un Nodo B y un controlador de red de radio (RNC). El RNC configura un RAB de EU para operar sobre un canal dedicado mejorado (E-DCH). Al menos uno entre la WTRU y el Nodo B informa estadísticas de tráfico de EU y estadísticas de performance de EU al RNC. El RNC ajusta luego la configuracion del RAB de EU, de acuerdo con las estadísticas de tráfico de EU y las estadísticas de performance de EU recibidas y la informacion reunida por el RNC mismo.

Abstract: A method and system for an enhanced uplink (EU) operation in a wireless communication system during soft handover are disclosed. The system comprises a wireless transmit/receive unit (WTRU), at least two Node-Bs, and a radio network controller (RNC). One Node-B may be designated as a primary Node-B, and the primary Node-B may control EU operation during soft handover including uplink scheduling and hybrid automatic repeat request (H-ARQ). Soft buffer corruption is avoided during soft handover by controlling H-ARQ by the primary Node-B. Alternatively, an RNC may control EU operation during soft handover including H-ARQ. In this case, an RNC generates final acknowledge/non-acknowledge (ACK/NACK) decision based on the error check results of the Node-Bs.

Abstract: A method for receiving a segmented communication begins by periodically transmitting the segmented communication. The segmented communication is received and each segment of the segmented communication is examined to determine if the segment is valid. If the segment is valid, then the segment is stored. If the segment is invalid, then the invalid segment is identified. The segmented communication is retransmitted and received. Only the identified invalid segments of the retransmitted communication are examined to determine if the previously invalid segments are now valid.

Abstract: A method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services. The system may include a radio network controller (RNC) in communication with a plurality of base stations. A control signal may be sent to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station sends a feedback signal to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.

Abstract: Un método y aparato de comunicación inalámbrica para coordinar Nodos B durante handover("traspaso") para transmisión de enlace ascendente (EU) mejorada. En una forma de realización, un controlador de red de radio (RNC) inicia un soft handover ("traspaso con continuidad") inter-Nodo B. Una unidad inalámbrica de transmisión/recepción (WTRU) establece conexiones de comunicación con una pluralidad de Nodos B. Uno en particular de ,los Nodos B es designado como un Nodo B primario, y cada uno de los otros Nodos B es designado como un Nodo B no primario. El RNC informa a todos los Nodos B que el Nodo B particular es un Nodo B primario. El Nodo B primario programa transmisión EU y lleva a cabo soft handover durante ACK/NACK. En otra forma de realización, el RNC inicia el soft handover para una WTRU conectada a un Nodo B fuente. El RNC envía un temporizador de activación al Nodo B fuente para establecer el tiempo para el handover. Tantos paquetes de datos con configuración negativa previa (NACK) como sea posible son priorizados para retransmisión en el Nodo B fuente antes de que finalice el temporizador de activación.

Abstract: A wireless hybrid (TDMA/CDMA) user equipment is disclosed. The user equipment receives and recovers signaled information of code and timeslot assignments of the user equipment to support a radio frequency communication. From the signaling information, an identifier of a plurality of assigned timeslots and an indication of a first and last code of a set of consecutive codes are recovered. The last code is identified by an identifier associated with the last code, and the same set of consecutive codes is assigned to each of the plurality of assigned timeslots.

Abstract: Method and apparatus for arranging wireless transmit/receive unit (WTRU) capability distribution between point to point (PtP) and point to multipoint (PtM) services. The method addresses PtP/PtM specific and common capabilities shared between PtM and PtP. The method utilizes procedures and different scenarios to coordinate establishment/release of PtP and PtM services and distribution of WTRU PtP/PtM capabilities within a universal mobile telecommunication system terrestrial radio access network (UTRAN).

Abstract: Se proveen un método, componentes y un sistema para implementar control de potencia para transmisiones de comunicación inalámbrica que provee, iter alia, una solución para el desajuste de potencia de transmisión inicial para datos NRT estimando un error de polarización basado y ajustando la potencia ed transmisión a través de una cantidad de compensación para una estimación promedio de error de polarización sobre todas las transmisiones de grupos de datos, como ser asignaciones Temp-DCH secuénciales en un sistema UNTS. Un procedimiento alternativo para un sistema UNTS estima el error de polarización en un RNC en base a una medición promedio de potencia de código de transmisión por una estación base y aplica una compensación de error de polarización a la potencia de transmisión DL inicial en el RNC.
