Abstract: Se divulgan métodos para dispositivos de comunicación con capacidad de transmisión y recepción simultáneas, donde un primer método es para la recepción de un paquete que comprende un encabezado y una carga útil y un segundo método es para la transmisión de un paquete que comprende un encabezado y una carga útil. El segundo método comprende transmitir al menos una parte del encabezado. El primer método comprende recibir al menos una parte del encabezado, intentar decodificar la parte del encabezado y (cuando la parte del encabezado se decodifica correctamente) transmitir una señal de acuse de recibo de encabezado. El segundo método comprende monitorear la recepción de una señal de acuse de recibo de encabezado y (cuando se detecta ausencia de la señal de acuse de recibo de encabezado) interrumpir la transmisión del paquete y programar el paquete para la retransmisión. También se divulgan aparatos, transceptores, dispositivos de comunicación y productos de programa informático correspondientes.

Abstract: A first radio device (20) receives a first radio transmission (101) from a second radio device (10). In response to reception of the first radio transmission (101) by the first radio device (20) being unsuccessful, the first radio device (20) sends a second radio transmission(103) to the second radio device (10). The second radio transmission (103) comprises an indication to the second radio device (10) that reception of the first radio transmission (101) by the first radio device (20) was unsuccessful. The first radio device (20) generates the second radio transmission (103) to be decodable by one or more other radio devices (30) than the second radio device (10) as comprising a positive acknowledgement message, indicating to the second radio device (10) that reception of the first radio transmission (101) by the first radio device was successful (20), as comprising a clear-to-send message to the second radio device (10), or as some other legacy message supported by the other radio device(s) (30).

Abstract: An access point is arranged for serving both wideband wireless stations and narrowband wireless stations where the narrowband wireless stations operate on a subset of the bandwidth on which the wideband wireless stations operate. The access point comprises a transceiver and a controller. The controller is arranged to schedule simultaneous usage of a first set of subcarriers for a wideband station and a first narrowband wireless station by causing the transceiver to transmit a first subcarrier suggestion, about the first set of subcarriers to be used, to the first narrowband wireless station and to transmit a modulation and coding scheme, MCS suggestion, about subcarriers including the first set of subcarriers to be used, to the wideband station. The suggested MCS is adapted to have increased robustness in view of any interference on a transmission from the wideband wireless station caused by a transmission from the first narrowband wireless station in the first set of subcarriers. A station arranged to communicate with the access point, and methods and computer programs are also disclosed.

Abstract: A method of a scheduling apparatus for multi-user scheduling, wherein the multi-user scheduling may-for example-be in an unlicensed communication environment. The method comprises transmitting a first signal to a first set of users wherein the first signal is indicative of a request for user-specific information, receiving-responsive to transmitting the first signal-a respective second signal from each of a second set of users wherein the second signal is indicative of the requested user-specific information, and scheduling-responsive to receiving the respective second signals-a third set of users based on the received second signals. The second set is a subset of the first set of users, and the third set of users is a subset of, or coincides with, the second set of users. Corresponding scheduling apparatus, wireless communication apparatus and computer program product are also disclosed.
