Publication number: 20210289428Abstract: A base station for a multiple-input, multiple-output (MIMO) array receives a message that includes information identifying the transmitting and receiving nodes. Based on whether the base station has access to up-to-date channel covariance matrices for the nodes, the base station selectively performs a clear channel assessment in an unlicensed frequency band concurrently with placing nulls in directions associated with the nodes. In some cases, the up-to-date channel covariance matrices are used to place nulls in the directions associated with the nodes concurrently with performing the clear channel assessment in response to the up-to-date channel covariance matrices being available to the base station. Placement of nulls in the directions associated with the nodes is bypassed in response to the up-to-date channel covariance matrices not being available to the base station.Type: ApplicationFiled: March 14, 2018Publication date: September 16, 2021Inventors: Adrian Garcia Rodriguez, Giovanni Geraci, David Lopez-Perez, Lorenzo Galati Giordano
