摘要： In an aspect, the present disclosure relates to a relay node (RN) operatively coupled with user equipment (UE), wherein the RN is configured to create one or more tunnels to enable transmission of data messages and control messages from the UE directly to a packet data network gateway (PGW). The present disclosure relates to methods and systems for tunneling user equipment (UE) traffic by creating one or more tunnels between a relay node (RN) and packet data network gateway (PGW) to prioritize control messages over data messages, wherein the one or more tunnels are created when the UE gets attached to the relay node (RN). Further, tunneling of the one or more control/non-access stratum (NAS) messages to the PGW can be performed over one of the higher priority tunnels such that when the NAS messages are received at the PGW or HGW, they can be forwarded to a mobility management entity (MME).

摘要： Aspects of the present disclosure aim at providing three pseudo-orthogonal waveforms that can be used for transmitting 3n bits (n bits over each waveform) at a given frequency. Use of such three pseudo-orthogonal waveforms can be used in applications such as QAM to create a 3-dimensional QAM, along with use in other like applications such as in Orthogonal frequency-division multiplexing (OFDM), Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), among others. The three pseudo-orthogonal waveforms can in general be used in any application where complex number algebra is used, and can help increase transmission capacity by additional 50%.

摘要： The present disclosure relates to transmission of information across a communication channel efficiently and without error. The present disclosure also enables transmission of information across a communication channel such that the Peak to Average Power Ratio (PAPR) is one (zero in decibels). The present disclosure also enables transmission of information across a communication channel such that the information transmitted is present only along a finite number of orthogonal frequencies. The present disclosure also combines advantages of both Single-carrier Transmission (SCT) and Multi-Carrier Transmission (MCT) systems (e.g. Orthogonal Frequency Division Multiplexing (OFDM) systems).
