Abstract: Disclosed are a resolution method for intent-based wireless network resource conflicts and an apparatus thereof. The method includes the following steps: periodically acquiring configured resource information about a current wireless network; pre-allocating resources required for a newly-added intent; and determining whether a pre-allocated resource configuration policy is incompatible with a resource configuration policy being executed in a current network. The apparatus includes: an interface module; a solution module; a feedback module; and a storage module. Through the relative priority of intent requirements, a bias of an implementation satisfaction degree of a network configuration policy is determined, and network resource conflicts of intent requirements with different priorities are solved.

Abstract: Embodiments provide a method, apparatus and device of reconstructing non-Kronecker structured channels, applicable to communications. A weight matrix is determined for emulating link characteristics of a reconstructed channel, and includes a weight corresponding to each ray mapped to a probe antenna. In each cluster, rays mapped to each probe antenna have different weights with each other. For each cluster, a time-varying fading channel impulse response of each ray of the cluster mapped to a probe antenna is calculated using the weight matrix. The time-varying fading channel impulse response includes a transition equation for each probe antenna describing mapping of rays of the cluster to the probe antenna. A transition matrix from each probe antenna to receiving antennas of a device under test is determined. A product of the time-varying fading channel impulse response of the cluster multiplied by the transition matrix serves as a channel impulse response of the cluster.

Abstract: A method and system for monitoring and processing a wireless signal are described. The method includes, if an authorized base station/Access Point (AP) receives a first abnormal signal from the terminal, which is identified as an unauthorized signal by a terminal, processing, by the authorized base station/AP, the first abnormal signal. If the authorized base station/Access Point (AP) receives a second abnormal signal from the terminal and the terminal cannot determine whether the second abnormal signal is the unauthorized signal or an authorized signal, identifying, by the authorized base station/AP, characteristics of the second signal and processing the second abnormal signal if the second abnormal signal is the unauthorized signal.
