A control node (200), a wireless device (204), an access point (202) and methods therein, to achieve estimation of path loss and channel response in a radio link between the wireless device and the access point. The control node (200) assigns one and the same pilot sequence to the wireless device and at least one other wireless device in communication with the access point, and further assigns different device-specific phase rotations to the wireless devices. The devices then apply their assi...
The present invention relates to a method of assigning a transmission timing to a radio terminal in a radio network system including at least a radio network node and a radio terminal and employing a time division duplex method dividing a transmission time in an uplink transmission time interval and a downlink transmission time interval for transmission between the radio network node and the radio terminal, comprising the following steps: determining a speed of movement of the radio terminal ...
A network node (110) and a method for downlink pilot signal assignment and transmission, and for data transmission. The network node has a plurality of antenna elements distributed over an area. The network node determines a respective Channel State Information (CSI) and/or a respective channel hardening degree for a wireless device (120) based on an uplink pilot signal. Possibly, the network node determines a mobility condition for the wireless device. Based on one or more out of: the determ...
An antenna arrangement comprises a body which in turn comprises a plurality of antenna devices, the antenna arrangement being characterized in that the body has a flexible structure and an elongated shape.
A disturbance mitigation method of a communication element for a distributed antenna system is disclosed. The communication element is associated with two or more antenna elements of the distributed antenna system.The method comprises acquiring channel condition information associated with at least two of a plurality of wireless communication devices served by the communication element, and partitioning the plurality of wireless communication devices into at least two groups based on the acqu...
