Abstract: A method includes acquiring, by a processor of an electronic device, information associated with channel and noise covariances. The method includes determining one or more time-domain rectangular filters based on the information associated with the channel and noise covariances. The method includes generating one or more convolutional kernels based on the one or more rectangular filters applied to the channel and noise covariances in a time-domain. The method includes generating a codebook based on the one or more convolutional kernels, the codebook comprising N codewords. Further, the method can include establishing a communication link to a gNB configured to: receive a reference signal from a user equipment; receive the codebook; calculate channel statistics using a low complexity algorithm; execute a decision tree classifier to select a codeword from the codebook stored in memory of the gNB; and apply the selected codeword as convolution kernel for channel estimation.

Abstract: An electronic device includes a transceiver configured to receive information related to an action request or rule. The electronic device further includes a processor operatively coupled to the transceiver. The processor is configured to determine that the action is location based, and identify a zone within which the electronic device is located. The identification of the zone is based on at least one of a first reception by the transceiver of at least one signal indicative of a location of the electronic device, and a second reception by the transceiver of at least one response to a transmission of a signal indicative of a location of the electronic device. The processor is further configured to trigger an action based on the action request or rule and the identified zone.

Abstract: A method includes generating relationship information representing spatial relationships between network elements in a wireless communication network. The method also includes dividing the relationship information into multiple communities of network elements, wherein network elements within each community have a higher correlation than network elements in different communities. The method also includes identifying, for a target network element, one or more community level key network elements and one or more local key network elements in the relationship information. The method also includes predicting traffic at the target network element using a temporal-spatial algorithm, wherein the temporal-spatial algorithm predicts the traffic based on temporal features derived from historical data and spatial features derived from the one or more community level key network elements and the one or more local key network elements.
