    Abstract: Dans certains modes de réalisation, un procédé dans un dispositif sans fil pour consigner des informations sur l'état d'un canal, csi, pour un processus csi est divulgué. Le processus csi correspond à une ressource de signaux de référence et à une ressource de mesures d'interférence. Selon ledit procédé, le dispositif sans fil obtient (810) une valeur d'ajustement associée au processus csi. Le dispositif sans fil estime (820) un canal effectif en fonction d'un ou plusieurs signaux de référence reçus dans la ressource de signaux de référence, applique (830) la valeur d'ajustement au canal effectif estimé, et obtient ainsi un canal effectif ajusté. De plus, le dispositif sans fil détermine (840) les informations d'état de canal en fonction du canal effectif ajusté ainsi que d'une interférence estimée en fonction de la ressource de mesures d'interférence. Finalement, les informations d'état de canal sont transmises (850) à un noeud de réseau.

    Abstract: Some embodiments provide a method in a wireless device for reporting channel state information, CSI, for a CSI process. The CSI process corresponds to a reference signal resource and an interference measurement resource. According to the method, the wireless device obtains (810) an adjustment value associated with the CSI process. The wireless device estimates (820) an effective channel based on one or more reference signals received in the reference signal resource, and applies (830) the adjustment value to the estimated effective channel, thereby obtaining an adjusted effective channel. Furthermore, the wireless device determines (840) channel state information based on the adjusted effective channel, and on interference estimated based on the interference measurement resource. Finally, the channel state information is transmitted (850) to a network node.

    Abstract: LAS REALIZACIONES EN LA PRESENTE MEMORIA SE REFIEREN AL MÉTODO EN UN NODO DE RED (301) PARA MANEJAR LA PROGRAMACION DE UN DISPOSITIVO INALÁMBRICO (305) EN UNA RED DE COMUNICACIONES (300). EL NODO DE RED (301) ESTÁ ADAPTADO PARA COMUNICARSE CON EL DISPOSITIVO INALÁMBRICO (305) EN UN CANAL RADIAL (310). EL NODO DE RED (301) ASIGNA DINAMICAMENTE UN CONJUNTO DE SUBTRAMAS NO CONSECUTIVAS EN LAS QUE EL NODO DE RED (301) DEBE TRANSMITIR DATOS AL DISPOSITIVO INALÁMBRICO (305) O RECIBIR DATOS DEL DISPOSITIVO INALÁMBRICO (305). EL NODO DE RED (301) TRANSMITE UN MENSAJE DE PROGRAMACIÓN DE MULTIPLE INTERVALO DE TIEMPO DE TRANSMISION, TTI AL DISPOSITIVO INALAMBRICO (305), CUYO MENSAJE DE PROGRAMACION DE TTI MULTIPLE COMPRENDE INFORMACION QUE INDICA LAS SUBTRAMAS NO CONSECUTIVAS DINÁMICAMENTE ASIGNADAS.

    Abstract: Some embodiments disclosed here provide a method in a wireless device (540) for reporting Channel State Information, CSI. The wireless device (540) is comprised in a wireless communications system (500). The method comprises receiving (1610) a CSI process configuration and a request for CSI information from a network node (560). The method further comprises reporting (1620) CSI for one or more CSI processes. The CSI is determined such as to reflect the state of the channel for a CSI reference resource. According to the method, the CSI reference resource is determined based on the number of configured CSI processes.

    Abstract: A method performed by a network node of a wireless communication network is provided for communicating an enhanced Physical Downlink Control Channel ePDCCH to a user equipment UE. The method comprises transmitting (606) a configuration message to the UE. The configuration message comprises an indication of a first mapping of the ePDCCH to resource elements belonging to a first ePDCCH set where the resource elements of the first ePDCCH set are different from resource elements used for a first type of signal. The method further comprises an indication of a second mapping of the ePDCCH to resource elements belonging to a second ePDCCH set where the resource elements of the second ePDCCH set are different from resource elements used for a second type of signal thereby enabling dynamically mapping ePDCCH to the resource elements of the first ePDCCH set or the second ePDCCH set. Further methods UEs and computer programs are provided for communicating an ePDCCH between a network node and a UE.
