A wireless device is configured to transmit radar signals at extremely low spectral density so that the receiver can be operated at the same time without saturating and thereby enabling full-duplex operation. To achieve sufficient range, beamforming is used together with a very long correlation time for detection of the radar signal, in which case the receiver can resolve backscattered or reflected radar signals far below the noise floor, while the bandwidth of the transmitted radar signal can be very high. The wide bandwidth enables the wireless device to maintain a low power spectral density while increasing output power, and also increase the depth resolution. The extremely low power spectral density even in the transmission beam direction makes the probability that communication will be disturbed very low. The high bandwidth calls for digital filters for both transmitted and received signals to equalize the radar frequency response characteristics of the radio unit.

A method for compressing Sounding Reference Signal (SRS) channel information in massive MIMO systems is disclosed. When SRS channel estimation is performed in a Radio Unit (RU), the resulting channel estimates create significant fronthaul bandwidth demands. The method transforms SRS channel estimates from antenna space to domains with superior energy compacting properties, enabling transmission of only a subset of channel values while preserving information quality. The method includes beam space compression using mathematical transforms such as DFT, SVD, or EVD to convert channel estimates to beam space, followed by selection of the most significant beams. Alternative embodiments include tap domain compression using DCT or DFT, and delay-Doppler domain compression. The methods support static beam space compression using predefined beam bases and dynamic compression employing adaptive beam bases. O-RAN C-Plane implementations extend Section Type 6 to support the compression methods. The methods significantly reduce fronthaul bandwidth requirements while maintaining channel estimation accuracy, enabling improved system capacity in massive MIMO deployments.

Technologies for dynamically reconfiguring a radio unit (RU) coupled to a cellular site of a cellular network are described. An RU is initially deployed with a default configuration having a plurality of radio frequency (RF) paths coupling the RU to a multi-port antenna that is serving a particular sector of a cell. Upon detecting increased demand for capacity within the particular sector, the RU is reconfigured by splitting the RU into a plurality of logical sub-sectors, each logical sub-sector of the RU having a respective subset of the plurality of RF paths coupled to a respective subset of ports of the multi-port antenna. A default configuration of 4T4R can be transformed into two 2T2R logical sub-sectors. A default configuration of 8T8R can be transformed into four 2T2R logical sub-sectors, or, two 4T4R logical sub-sectors, or, two 2T2R and one 4T4R logical sub-sector.

Systems and methods are described for implementing a distributed unit in a radio access network that executes code on behalf of mobile devices.

The edge server may preload computing environments with code for which a mobile device is likely to request execution (e.g., because a particular application is executing on the mobile device), and may determine whether to execute code on the edge server or on a cloud provider network.
