Abstract: A broadcast signal transmission occurs concurrently with device-specific, directional transmissions but without substantially interfering with the directional transmissions, based on transmitting the broadcast signal in the null spaces of the directional transmissions. Specifically, transmission of the broadcast signal relies on beamforming precoder values formed from one or more orthonormal basis vectors for the null space of a channel estimate matrix representing the channels between a multi-element antenna array and the wireless devices targeted by the device-specific transmissions. The approach concentrates most of the broadcast signal energy for each subcarrier on a single antenna element for good broadcast-signal coverage while still yielding a beamforming solution that substantially avoids broadcast-signal interference at the devices targeted for directional transmission.

Abstract: A base station (11) of a wireless cellular communication network operating in unlicensed spectrum adjusts (118) the robustness of a downlink transmission in response to the power level of any interference encountered in the channel and the source of the interference. The base station (11) estimates (110) whether the source of interference encountered is a eLAA or WLAN network (110). An offset to a transmission format—a measure of transmission robustness to noise and interference—is calculated (112) in response to the interference power level and the source of the interference. An initial transmission format is adjusted (118) by the offset, and data are transmitted (120) to a UE using the adjusted transmission format. In other embodiments, the base station (11) may compare its interference to that detected by the target UE, to ascertain whether the two likely have the same source.
