Abstract: A method includes receiving CSI frames among P CSI frames transmitted from another electronic device. The method includes estimating a CSI from each of the received CSI frames as an available CSI estimate. The method includes identifying an impairment model accounting for inclusion of amplitude or phase errors of an estimated CSI corresponding to a p-th CSI frame among the P CSI frames. The method includes compensating, via the impairment model, for the errors in amplitude and phase of P CSI estimates. Compensating for the errors in amplitude and phase of the P CSI estimates can be based on: approximating a missing CSI estimate based on the available CSI estimates; determining an AGC gain value; or computing the errors in the phase based on a weighted least-squares solution. The method includes estimating a breathing rate of a subject based on different spatial dimensions of the P compensated CSI estimates.

Abstract: Methods and apparatuses for detecting conditions associated with a target wake time (TWT) parameter adjustment. A communication device comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive information including packets associated with a TWT. The processor is configured to determine a network service type based on the packets, and when the determined network service type is a real-time service type: determine whether a condition associated with the TWT is satisfied, and modify the TWT based on the condition.

Abstract: A method includes obtaining input features based on network traffic received during a time window. The method also includes generating multiple network service type predictions about the network traffic during the time window using a machine learning (ML) classification system operating on the input features. The method also includes storing the multiple network service type predictions in different time steps in a first-in first-out (FIFO) buffer and generating decisions about a presence of each of multiple service types in the network traffic using a voting algorithm. The method also includes reducing fluctuations in the generated decisions using a logic-based stabilizer module to generate a final network service type decision.

Abstract: A method includes obtaining one or more channel quality and performance indicators of a user equipment (UE) from multiple transmit-receive points (TRPs) in a coordinated multipoint (CoMP) cluster. The method also includes generating a set of performance metrics from the one or more channel quality and performance indicators. The method also includes determining a number of helping layers for multiplexing joint transmission (Mux-JT) in the CoMP cluster based on the set of performance metrics. The method also includes selecting a modulation and coding scheme (MCS) for the Mux-JT based on at least one channel quality indicator (CQI) of the UE.

Abstract: Methods and apparatuses in a wireless communication system. A base station (BS) includes a transceiver and a processor. The processor regulates a transmit power in a direction of an earth station or a predefined receiver by: calculating a power flux density for the BS to the earth station or the predefined receiver; calculating an equivalent antenna gain for other base stations; calculating a directional power back-off level for the other base stations with respect to the earth station or the predefined receiver; generating a restricted precoding matrix indicator based on the calculated directional power back-off level; generating an N1-N2 bitmap for the BS; and applying the N1-N2 bitmap for signal transmission to at least one UE. The N1-N2 bitmap is generated based on: physical parameters of the earth station of the predefined receiver; physical parameters of the BS; an operator input metric; or restricted precoding matrix indicator.
