摘要: An embodiment communication system and method for using multiple-input multiple-output use. Kronecker model to determine a symbol coding formulation that achieves ergodic capacity for high signal-to-noise ratios (SNRs). The lower bound on this capacity is achieved by input signals in the form of the product of an isotropically distributed random Grassmannian component and a deterministic component comprising the eigenvectors and the inverse of the eigenvalues of the transmitter covariance matrix.

摘要: Cell switch-off (CSO) methods for base stations (BSs) in a wireless network are provided. The CSO methods utilize quality of service (QoS) requirement information of user equipments (UEs) to determine which BS to switch off according to a pre-defined criteria. The criteria is defined so that impact of switching off a BS on the UEs may be reduced, and/or QoS requirements of at least some of the UEs may be satisfied if a BS was switched off.
