Abstract: Precedence and preemption may be extended for remote terminals. In an example embodiment, a communication node implements a method with respect to a communications system that implements an enhanced multi-level precedence and preemption (eMLPP) scheme. The method includes acts of receiving, mapping, and transmitting. An incoming connection establishment communication having a priority-header value that indicates a priority for a connection to be established is received at the communication node. The priority-header value is mapped to an eMLPP value that indicates a precedence and preemption level for the connection to be established. An outgoing connection establishment communication having the eMLPP value is transmitted from the communication node.

Abstract: An air interface for use with a mobile satellite system that extends the baseline LTE interface modulation and coding from 3GPP. The LTE OFDM and S-FDMA technologies are used in the lowest FDD E-UTRA assigned bandwidth of 1.4 MHz but can be extended up to 7 other bands. The key differentiator for S-LTE from LTE would be the use of 32-ary Amplitude Phase Shift Keying (32-APSK) in the uplink channel for S-FDMA with LDPC and turbo coding and 64-QAM in the downlink channel for OFDM with LDPC and turbo coding. This new mechanism for S-LTE with new combination of coding will allow a robust channel model for S-LTE air interface and will enable the S-LTE air interface to have an efficient link budget. The S-LTE air interface of the present invention can be implemented in 700 MHz, 1.5 GHz, 2.1 GHz and 2.6 GHz bands or any future bands allocated for the specific air interface.
