Abstract: The invention relates to devices in a wireless network transmitting uplink beacons such as a network node comprising a transceiver for communication with at least one User Equipment, UE. The network node is configured to receive an at least one uplink beacon corresponding to the at least one UE, and to determine a group comprising at least a first UE and a second UE, based on received uplink beacons from the first UE and the second UE. The network node is also configured to determine uplink beacon reconfiguration for each UE in the group, comprising information specifying a group uplink beacon, and information specifying a UE configuration for the UEs of the group, indicating each UE of the group either as being a UE for sending said group uplink beacon, or as a UE for receiving said group uplink beacon.

Abstract: A network node includes an antenna array having a plurality of antenna sub-arrays. A switching device is coupled to the antenna array, the switching device being configured to connect at least two input signals to respective ones of the plurality of antenna sub-arrays. A processor is configured to determine a channel capacity, wherein based on the channel capacity, the processor is configured to control the switching device to switch a connection of the at least two input signals to different ones of the plurality of antenna sub-arrays to change one or more of an inter-distance between the respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.

Abstract: Implementations describe a user equipment, an access node, and to methods for a user equipment and for an access node. The user equipment includes a receiver configured to receive a downlink control signal (CTRLS) over a downlink control channel (PDCCH) from an access node. The user device also includes a processor configured to, when the user equipment is in a Radio Resource Control (RRC) connected mode, switch on the receiver at a time point (tstart_symbol) when a symbol comprising the downlink control signal (CTRLS) starts in time domain. The processor is further configured to switch off the receiver at a time point (tend_symbol) when the symbol comprising the downlink control channel (CTRLS) ends in time domain.

Abstract: A network node (110, 120, 130) and a method therein for radio access resource allocation of a mobile station (140) is disclosed. The network node (110, 120, 130) comprises a receiver (630), configured to receive at least one first parameter value associated with a radio communication condition of the mobile station (140), at least one second parameter value associated with communication capabilities of the mobile station (140), and at least one third parameter value indicating operability in MRTD of the mobile station (140). Further the network node (110, 120, 130) comprises a processor (620), configured to allocate at least one radio access resource to the mobile station (140), based on the received parameter values. In addition, the network node (110, 120, 130) comprises a transmitter (610), configured to inform the mobile station (140) of the at least one allocated radio access resource.

Abstract: The present disclosure relates to a network node having a processor and a transceiver. The processor is configured to select at least one user device if a Channel Estimation Timer (CET) for a radio channel between the network node and the at least one user device is valid, and to schedule data transmission to the at least one selected user device. The transceiver is configured to perform the scheduled data transmission to the at least one selected user device. The present disclosure also describes a corresponding method, a wireless communication system including such a network node, a computer program, and a computer program product.

The user device includes a receiver configured to receive at least one downlink signal from an access node. The user device further includes a processor configured to measure the at least one downlink signal at two time instants, to determine if a difference of the measured at least one downlink signal at the two time instants exceeds a threshold, and to generate, when the difference exceeds the threshold, at least one uplink transmission. The user device further includes a transmitter configured to transmit the at least one uplink transmission over an uplink random access channel.
