摘要： Disclosed is a method for suppression, at a first radio access node, of interference caused by one or more other radio access nodes when the first radio access node and/or the other radio access nodes operate in a full duplex mode. The full duplex mode comprises simultaneous transmission and reception in a same frequency interval. The method comprises acquiring measurements indicative of channel conditions between the one or more other radio access nodes and the first radio access node, wherein channel conditions indicate interference caused at the first radio access node by the one or more other radio access nodes. The method also comprises selecting a set of radio access nodes from the one or more other radio access nodes based on the channel conditions between the one or more other radio access nodes and the first radio access node, and determining an uplink receive filter for suppression of interference at the first radio access node based on the channel conditions between the selected set of radio access nodes and the first radio access node. In some embodiments, the method further comprises controlling one or more user devices served by the first radio access node to apply an uplink transmit beamforming which is based on the uplink receive filter. Corresponding user device method, apparatuses, network node, user device, and computer program product are also disclosed.

摘要： According to certain embodiments, a method is disclosed for use in a wireless device. The method comprises transmitting uplink data to a network node. The uplink data is transmitted according to a semi-persistent scheduling (SPS) configuration obtained from the network node. The uplink data is transmitted without transmitting padding when no data is available for transmission. The method further comprises retransmitting the uplink data to the network node until receiving an indication to transmit new uplink data. The indication is received from the network node via a control channel.

摘要： It is presented a method performed by a network node of a wireless communication network for scheduling a wireless device in uplink. An uplink signal structure is configured to be used by the wireless device and the network node, wherein the uplink signal structure defines transmission subframes divided into symbol periods. The network node applies a short Transmission Time Interval, sTTI, scheduling interval, wherein each sTTI is shorter in time than a subframe and each sTTI comprises at least one symbol period. The method comprises: transmitting a control information message to the wireless device for an sTTI scheduling interval, the control information message comprising uplink scheduling information assigned to the wireless device, the uplink scheduling information indicating a position and a length for at least one of a reference signal and data in the uplink sTTI.
