Abstract: Se describe un método y aparato para transportar reportes de retroalimentación desde una parte receptora de datos (300) para datos recibidos desde un parte emisora de datos (302) en una conexión inalámbrica. Una pluralidad de recursos de retroalimentación (304) asignados a diferentes códigos de información de retroalimentación está reservada para la parte receptora de datos para transmitir los reportes de retroalimentación. Después de verificar si los datos se recibieron correctamente o no, la parte receptora de datos selecciona un recurso de retroalimentación (FR2) con un código que información de retroalimentación que corresponde a uno o más reportes de retroalimentación en los datos recibidos. La parte receptora de datos envía entonces información de retroalimentación en el recurso de retroalimentación seleccionado a la parte emisora de datos, transportando con esto el código de información de retroalimentación correspondiente. De este modo, se pueden transportar reportes de retroalimentación múltiples en un recurso de retroalimentación simple a la parte emisora de datos mientras aún retiene las propiedades de portador simple.

Abstract: A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

Abstract: Método y aparato en una unidad de comunicaciones (400) que emplea una disposicion TDD inalámbrica o FDD semi duplex al comunicarse con una parte transmisora de datos, para programar informes de realimentacion correspondientes a los bloques de datosde las sub-tramas RX recibidas, en las sub-tramas TX disponibles para la transmision. Una unidad de obtencion (402) de la unidad de comunicaciones recibe los parámetros de asignacion (P) para la conexion, donde la cantidad de informes derealimentacion requeridos es mayor que la cantidad de informes de realimentacion admitidos. Una unidad de programacion (404) de la unidad de comunicaciones programa entonces los informes de realimentacion (FR) en las sub-tramas TX disponibles, deacuerdo con una regla de propagacion predeterminada también conocida por la parte transmisora de los datos, que dicta que los informes de realimentacion se propagan o distribuyen de forma pareja por las sub-tramas TX disponibles. De este modo, puedereducirse la cantidad de informes de realimentacion en una sub-trama TX.

Abstract: The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

Abstract: The present invention relates to methods in a communication system providing the steps of determining a set of spatial transport formats, and signalling a selected active set of transport formats to one or several mobile terminals. The transport formats are adjustable by means of adapting the parameters of their complex transmission weights and/or their transmission power by evaluating collected channel management information, e.g. feedback information received from the mobile terminals, in order to optimise the aggregate data throughput subject to quality and fairness requirements. Further the present invention allows to evaluate a plurality of feedback information received from the various mobile terminals, determining applicable data rates for each of the data streams associated to the transport formats, determining from said evaluation a scheduling scheme for scheduling data streams to said mobile terminals, and assigning applicable data rates to each of said scheduled data streams.

Abstract: A communication device operating in a communications network can determine to transmit information using repetition to a network node operating in the communications network during a random access, RA, procedure. The communication device can further determine a subset of preambles based on determining to transmit the information using repetition. Responsive to determining the subset of preambles, the communication device can determine a preamble of the subset of preambles to transmit to the network node to indicate a type of the repetition. The communication device can further transmit the preamble to the network node. The communication device can further transmit the information using the type of repetition to the network node.
