Abstract: A method of channel estimation for an antenna array is disclosed. The method includes, receiving a signal transmitted by the antenna array, obtaining a neural network model trained for channel estimation using the received signal, inputting a representation of the received signal into the neural network model and generating a channel estimate for the received signal, and deciding whether to employ a further neural network model for the channel estimation.

Abstract: A method including: determining a respective first amount of resources each with a respective first power and a non-aggressive MCS such that a target value is guaranteed for a BLER of a transmission to a terminal under a channel estimate of a channel and a SINR estimate; and instructing a transmission device to perform the transmission using the non-aggressive MCS on the first amount of the resources each with the first power, wherein the transmission device may perform hypothetically the transmission using an aggressive MCS on a second amount of the resources each with a respective maximum available power such that the target value is guaranteed for the BLER under the assumed conditions; the first amount of the resources is larger than the second amount of the resources, the respective first power is less than the respective maximum available power.

Abstract: One radar excitation signal has a first burst duration and a first sampling period. Another radar excitation signal has a second burst duration and a second sampling period. The first sampling period of the first signal is configured for scanning a velocity range and the second sampling period of the second signal is configured for scanning a portion of the velocity range, and the first burst duration is smaller than the second burst duration. The at least two radar excitation signals are embedded into a frame structure for a wireless communications system. At least one radar operation comprising at least one transmission based on the frame structure is performed. In this way the overhead of the radar excitation signals on the air interface of the wireless communications system may be controlled, while supporting a fine velocity resolution and a sufficiently large maximum velocity for a monitored target.
