Abstract: A method for predicting channel state information is described. The method includes determining whether or not geodesic prediction is to be performed and transmitting the determination of whether or not geodesic prediction is to be performed in a first part of uplink control signaling. In response to determining that geodesic prediction is not to be performed, the method includes transmitting a current channel estimate in a second part of uplink control signaling, and in response to determining that geodesic prediction is to be performed, the method includes transmitting either a determined current value of a tangent vector, or a determined step size parameter, or both the determined current value of the tangent vector and the determined step size parameter in the second part of uplink control signaling. Channel state information is predicted based on information provided in the first and second parts of uplink control signaling.

Abstract: A method, apparatus, and computer readable medium facilitate network control by allowing a base station to predict when power class fallback will occur in user equipment. In the context of a method, the method receives a message comprising information about at least one of a first power class or a maximum duty cycle associated with user equipment. The method determines, based on at least the first power class or the maximum duty cycle, a threshold duty cycle for the user equipment. The method causes the threshold duty cycle to be transmitted to the user equipment. The method determines an uplink transmission schedule for the user equipment based at least on the first power class or the maximum duty cycle. The method receives, from the user equipment, a report that the threshold duty cycle has been exceeded by the user equipment.

Abstract: To enable dynamic waveform switching, one or more instructions on how to determine a waveform amongst at least a first waveform and a second waveform for at least one uplink transmission based at least on frequency domain resource allocation for the at least one uplink transmission may be transmitted in a network, or apparatuses may comprise one or more of the one or more instructions. The one or more instructions associate at least resource block regions with waveforms. The one or more instructions may be applied to determine, based on a frequency domain resource allocation for an uplink transmission, a waveform for the uplink transmission at least according to a resource block region in the frequency domain resource allocation. The waveform determined is then used in the uplink transmission.
