Abstract: A system and method for user selection in distributed multiple-input, multiple-output (MIMO). The system performs a method that includes configuring a first channel state information-reference signal (CSI-RS) resource set for a serving transmission point (TRP) and a second CSI-RS resource for a concatenated channel, wherein the concatenated channel is between a virtual panel and the apparatus, the virtual panel comprising distributed panels from a serving TRP and a helping TRP. The method also includes computing a metric as a function of one or more quantities included in one or more measurement reports, received from a user equipment (UE), for the concatenated channel and at least one of the serving TRP channel or the helping TRP channel. The method also includes configuring, based on the metric, the UE for one of: a legacy transmission or a distributed MIMO transmission.

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: A method includes scanning for registered fine-time measurement (FTM)-enabled Wi-Fi nodes to generate a list of the FTM-enabled Wi-Fi nodes. The method also includes performing a ranging operation by (i) selecting nodes to range with from the list of the FTM-enabled Wi-Fi nodes and (ii) processing ranging responses from the selected nodes to generate distance measurements. The method further includes estimating a position of a device based on the distance measurements generated from the ranging operation.

Abstract: A method includes determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round. The method also includes determining multiple UWB silent periods in the ranging round based on an arrangement of the inactive slots. The method also includes determining a sleep-wake-up schedule that aligns with at least one selected silent period of the multiple UWB silent periods in the ranging round, the sleep-wake-up schedule to be used for Wi-Fi communication. The method also includes waking up a Wi-Fi station (STA) for the Wi-Fi communication during the at least one selected silent period, then going back to sleep according to the sleep-wake-up schedule.

Abstract: A method includes determining, for each time interval in a series of time intervals, (i) whether at least one wireless signal measurement was received in the time interval, each wireless signal measurement associated with a pair of anchors, and (ii) whether at least one step was detected in the time interval. The method also includes selecting a state of a tracking filter state machine based on whether the at least one wireless signal measurement was received in the time interval and whether the at least one step was detected in the time interval. The method further includes determining a location of an object using the tracking filter state machine based on the selected state.

Abstract: A method includes determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round. The method also includes determining multiple silent periods in the ranging round based on an arrangement of the inactive slots. The method also includes determining a target silent period in the ranging round, among the multiple silent periods, to be used for WiFi communication. The method also includes determining multiple target wake time (TWT) parameters such that a TWT session period defined by the TWT parameters overlaps with the target silent period. The method also includes determining one or more second silent periods preceding the target silent period in which the TWT parameters can be negotiated with an access point (AP) for the WiFi communication. The method also includes negotiating the TWT parameters with the AP during the one or more second silent periods.

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.
