Abstract: Various aspects include methods for managing communication links with different networks. A user equipment (UE) processor may start a first retry timer in a first network communication module in response to receiving a connection reject message from a first communication network, send a value of the first retry timer to a second network communication module, start a second retry timer in the second network communication module based on the value of the first retry timer, send a service request from the second network communication module to a second communication network, and send a connection success message from the second network communication module to the first network communication module upon establishing a communication link with the second communication network before the second retry timer expires. The first communication network may be a terrestrial cellular network and the second communication network may be a satellite communication network.

Abstract: Aspects of the present disclosure implement techniques of a new 3D waveform coding scheme that leverages the spatial properties of 5G NR systems. Specifically, in 5G systems, each UE location may be characterized by three parameters: propagation delay (tp), angle of elevation (θ), and angle of azimuth (φ). Global coding matrix may be generated by linear combination of these three attributes and a unique lattice code may be generated for each UE at different locations from the base station. Thus, considering the coding gain increases with increasing the distance between the codes, aspects of the present disclosure take advantage of geometrical properties of lattice. Particularly, within the 3D waveform coding, if lattice distance between co-beamed UEs is determined to be greater than threshold radius, a conjugate lattice code for the UEs may be applied in accordance with aspects of the present disclosure.
