Abstract: A multi-user multiple-input multiple-output (MU-MIMO) scheduling method is disclosed for scheduling transmission from a plurality of transmission instances to a plurality of receivers. The method comprises acquiring, for each pair of a transmission instance and a receiver, a communication quality metric and forming a first group of receivers from the plurality of receivers. The first group of receivers is formed by selecting a first receiver as a first group member and associating a first transmission instance to the first receiver and—when a plurality of communication quality metrics of the first transmission instance and not yet selected receivers fulfill a first criterion for sufficient communication quality—selecting a second receiver from the not yet selected receivers as a second group member and associating a second transmission instance to the second receiver.

Abstract: Methods of operation of a wireless device are provided. In particular, Media Access Control (MAC) protocol aspects are disclosed relating to Licensed Assisted Access (LAA) cells and, more generally, to cells of a cellular communications network operating in an unlicensed frequency spectrum. According to one aspect, a method of operation of a wireless device comprises transmitting an Uplink (UL) transmission on a cell for a corresponding UL Hybrid Automatic Repeat Request (HARQ) process, the cell operating in an unlicensed frequency spectrum, and setting a locally maintained status for the UL HARQ process to Acknowledgement (ACK) based on an assumption that the UL transmission was successful.

Abstract: An eNB and a method for use in a base station (eNB) for configuring a UE to be awake for a longer duration in order to detect eNB transmission after the end of initial Signalling.

Abstract: A first communication device determines one or more parameters for transmitting on an uplink control channel in an unlicensed band to a second communication device operating in a wireless communications network. The one or more parameters comprise an indication of a duration of a channel sensing period.

According to a method performed by the second communication device operating in the wireless communications network, the second communication device determines the one or more parameters. The second communication device then initiates transmitting the determined one or more parameters to the first communication device.
