Abstract: Systems and methods for processing a received radio signal in a communication system are described. Initial time synchronization is acquired using a trace operator. Then, a number of channel taps for use in further processing is determined based on the initial time sync, also using a trace operator. A final synchronization position is then selected using the number of channel taps and, if multiple branches are employed to receive the signal, using a determinant-based technique. Finally, a channel estimate is determined using the final synchronization position.

Abstract: Un nodo de red 606,608 y un método para el reordenamiento del Protocolo de Convergencia de Paquetes de Datos (PDCP). El nodo de red está operando en una red de comunicaciones inalámbricas 600. El nodo de red almacena en el búfer en orden una o más primeras unidades de datos recibidas fuera de orden por una capa PDCP, caracterizado porque las una o más primeras unidades de datos se reciben de una capa inferior durante un primer período de tiempo, y caracterizado porque la capa inferior es una capa debajo de la capa PDCP. Cuando el primer período de tiempo ha expirado, el nodo de red envía las una o más primeras unidades de datos almacenadas en el búfer en orden a una capa superior e inicia un segundo período de tiempo. Además, el nodo de red envía, a la capa superior y en cualquier orden, una o más segundas unidades de datos recibidas desde la capa inferior durante el segundo período de tiempo.

Abstract: A method for localized congestion exposure within a local loop in a cellular network that is performed by a localized congestion exposure receiver node of the local loop. The method includes receiving downlink packets destined for a downstream user device. The downlink packets have headers that indicate a level of congestion experienced by the downlink packets. The headers also indicate a level of expected downstream congestion declared by an upstream node. The method also includes forwarding the downlink packets to the downstream user device through a wireless connection. The method further includes sending packets upstream that have feedback indicative of the level of congestion experienced by the downlink packets and any congestion experienced within the localized congestion exposure receiver node.

Abstract: According to a first aspect, the invention can be embodied as a method of controlling a radio access network entity of a data unit communication network 5 and as a corresponding radio access network entity, said radio access network entity being involved in providing a transport service to a radio terminal of said data unit communication network, said transport service being characterized by a set of values associated with respective service quality parameters, said method comprising monitoring a communication quality at the radio access level of a 10 communication between said terminal and an access point of said radio access network, and setting a congestion indication marking in data units of said transport service if said communication quality fulfils a radio communication degradation condition.

Abstract: Un método para adaptar a diferentes condiciones de funcionamiento la transmisión de contenido multimedia codificado (802) en una red de conmutación de paquetes, donde están disponibles una serie de formatos (808) de transmisión, en el que cada formato (808) de transmisión define una combinación de por lo menos dos características; comprendiendo dicho método las etapas de: recibir (1105) información acerca de si la métrica de rendimiento del contenido multimedia codificado (802) transmitido satisface un objetivo predeterminado (814), si la métrica de rendimiento del contenido multimedia codificado (802) transmitido no satisface el objetivo predeterminado (814); seleccionar (1106) otro formato (808) de transmisión entre los formatos (808) de transmisión disponibles, hasta que la métrica de rendimiento del contenido multimedia codificado (802) transmitido satisfaga el objetivo predeterminado, caracterizado por que dichas características son combinadas entre las de agregación de tramas, velocidad binaria de codificación fuente y redundancia.

Abstract: A base station detects the transition of a mobile station from a DTX mode to a continuous transmission mode. The base station schedules an uplink tra nsmission by the mobile station during an uplink transmission period while t he mobile station is in DTX mode and receives an uplink LLC PDU from said mo bile station during the scheduled uplink transmission periods. The base stat ion determines the operating mode of the mobile station based on the size of the received uplink LLC PDU.

Abstract: Perceptually relevant non-speech information can be preserved during encoding of an audio signal by determining whether the audio signal includes such information. If so, a speech/noise classification of the audio signal is overriden to prevent misclassification of the audio signal as noise.

Abstract: Multi-channel audio signals are used to create a main signal, typically a mono signal, and a side signal (x side). A number of encoding schemes (81) for the side signal (x side) are provided. Each encoding scheme (81) is characterised by a set of sub-frames (90) of different lengths. The total length of the sub-frames (90) corresponds to the length of the encoding frame (80) of the encoding scheme (81). The encoding scheme (81) to be used on the side signal (x side) is selected dependent on the present signal content of the multi-channel audio signals. In a preferred embodiment, a side residual signal is created as the difference between the side signal and the main signal scaled with a balance factor. The balance factor is selected to minimise the side residual signal. The optimised side residual signal and the balance factor are encoded and provided as encoding parameters representing the side signal.

Abstract: Polyphonic signals are used to create a main signal, typically a mono signal , and a side signal (Xside). A number of encoding schemes (81) for the side signal (Xside) are provided. Each encoding scheme (81) is characterised by a set of sub-frames (90) of different lengths. The total length of the sub- frames (90) corresponds to the length of the encoding frame (80) of the encoding scheme (81). The encoding scheme (81) to be used on the side signal (Xside) is selected dependent on the present signal content of the polyphoni c signals. In a preferred embodiment, a side residual signal is created as the difference between the side signal and the main signal scaled with a balance factor. The balance factor is selected to minimise the side residual signal. The optimised side residual signal and the balance factor are encoded and provided as encoding parameters representing the side signal.
