Abstract: A communication arrangement, a method for the operation thereof and a computer program including instructions causing a computer to perform the method for the operation of the communication arrangement are disclosed. The communication arrangement includes one or more digitally controllable scatterers, DCSs, an assignment circuitry and a DCS control circuitry. The assignment circuitry is configured to assign a respective base phase shift pattern to each of the one or more DCSs. The DCS control circuitry is configured to operate, during a sequence of time intervals, each DCS of the one or more DCSs to provide a respective sequence of phase shift patterns that is obtained by applying, during each time interval of the sequence of time intervals, a respective additional phase shift from a sequence of additional phase shifts for the respective DCS to the base phase shift pattern assigned to the respective DCS.

Abstract: A sensing apparatus for detecting speed bumps or potholes on a road is disclosed. The sensing apparatus comprises a telemetric sensing system configured to collect a plurality of position vectors by telemetric sensing of a road surface, wherein each position vector extends from a common origin to a respective point on the road surface and wherein each position vector has a length and a direction. The sensing apparatus further comprises a processing circuitry configured to detect a road flatness exception by evaluating the lengths of the position vectors. Thus, an improved apparatus for detecting road irregularities such as speed bumps or potholes on a road is provided. The sensing apparatus remains functional in low light conditions, e.g., at night, and also in the presence of reverberation of the vehicle.

Abstract: A device, in a training phase, obtains Channel State Information (CSI) for one or more links between another device and at least one Access Point (AP), and in the training phase, estimates location information of the other device based on at least one geometric localization technique; and generates a database comprising CSI of the one or more links, each CSI being associated with an estimated location information. Further, a device, in a testing phase, obtains a database from another device, wherein the database comprises CSI of one or more links, each CSI being associated with an estimated location information, and in the testing phase, the device estimates CSI for one or more links between the device and at least one AP, and determine location information based on the estimated CSI of the one or more links and the database.

Abstract: Embodiments relate to an apparatus for adjusting channel quality indicator measurements of a channel between a client device and a serving device within a wireless communication system. The apparatus includes a controller adapted to receive, from the client device, a first information and, when the client device is in a handover zone, a second information. The controller is further adapted to transmit according to a switching sequence either the first information alone or the first information together with the second information. The apparatus also includes an adjustment function entity adapted to receive the first information together with the second information and adapted to adjust the first information based on the second information by modifying it or keeping it unchanged. The first information is related to the CQI measurements, while the second information is related to a handover (HO).

Abstract: A method and apparatus are provided for sending pulses from a sender device to a receiver device in a transmission channel. The pulses represent information symbols, with each of these pulses being associated with a time slot in a symbol time. The method includes a training step that is carried out before sending payload information and that includes sending a training sequence made up of two parts. A first part of the training sequence includes at least one pulse of energy that is greater than the energy of a pulse carrying payload information. There are a large number of time slots between the sending of the pulse and the sending of the next pulse. A second part of the training sequence includes a set of pulses known in advance and similar to the pulses used for carrying payload information, the energy of each of these pulses being equivalent to the energy of a pulse carrying payload information.
