Abstract: Techniques are disclosed for generating a featureless low-probability-of-intercept/low-probability-of-detection (LPI/LPD) waveform via a continuously variable symbol rate transmission. A continuous-phase-modulation (CPM) signal can be represented with a phase trellis. During each symbol duration, the trellis is traversed in either a positive or negative direction in a continuous fashion from the starting phase value to the end phase value. The rate at which the trellis is traversed is varied continuously as a time-varying function. The time-varying phase velocity function, or instantaneous symbol rate, is a type of spreading code or secret key shared between the transmitter and receiver. The disclosed techniques can be implemented with CPM compromising the constant-modulus property of CPM signals.

The CU may identify a scheduling plan indication (SPI) for one or more scheduling nodes in a network, based at least in part on the received measurement reports. The SPI may specify a pattern of scheduling states, over a period of time, to be used by the one or more scheduling nodes to schedule communication resources for one or more UEs in the network.

In some cases, the scheduling nodes may identify tentative SPIs, which the CU may pass amongst other scheduling nodes for distributed scheduling coordination schemes.
