The processor receives, from each camera, an image comprising captured features from the calibration pattern. It determines and stores extrinsic calibration parameters (ECPs) for each camera that map coordinates of the features to camera coordinates and that are usable for subsequent normal operation of the cameras, the ECPs being determined from the image features.
An apparatus to be used in a UE in a mobile communication network to communicate with a base station, includes a memory configured to store a RRC message, and processing circuitry configured to decode the RRC message to obtain BWP configuration information and mapping information, identify one or more UL BWPs and one or more DL BWPs within a carrier bandwidth per Serving Cell based on the BWP configuration information, identify one or more SR configurations which a LCH is mapped to for the UL BWPs based on the mapping information, the LCH being mapped to none or one SR configuration for each of the UL BWPs, identify activation of a UL BWP of the UL BWPs, and encode an SR on a PUCCH based on a SR configuration for the UL BWP.

METHODS AND APPARATUSES FOR CONTROLLING A BANDWIDTH USED FOR PROCESSING A BASEBAND TRANSMIT SIGNAL, RECEIVER FOR A WIRELESS COMMUNICATION SYSTEM, AND METHOD FOR A RECEIVER
A method for controlling a bandwidth used for processing a baseband transmit signal by a transmit path of a transmitter is provided. The method includes generating a first comparison result by comparing, to a threshold value, a first number of physical resource blocks allocated to the transmitter for a first transmission time interval. Further, the method includes generating a second comparison result by comparing, to the threshold value, a second number of physical resource blocks allocated to the transmitter for a subsequent second transmission time interval. The method additionally includes adjusting the bandwidth based on the first and the second comparison results.
