CONCURRENT CODE DIVISION AND FREQUENCY DIVISION SIGNALING VIA AN UPLINK CHANNEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17944036 titled 'CONCURRENT CODE DIVISION AND FREQUENCY DIVISION SIGNALING VIA AN UPLINK CHANNEL

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communication at a user equipment (UE) using code division multiple access (CDMA) uplink signals.

• UE asynchronously transmits CDMA uplink signals to a network entity.
• Uplink channel may be shared with orthogonal frequency multiplexing (OFDM) signaling from other UEs.
• UE indicates capability for communicating with CDMA waveforms to the network entity.
• UE receives parameters for using CDMA waveforms.
• Uplink channel can be a random access channel (RACH) or a data channel supporting different types of transmissions.

Potential Applications

• Mobile communication networks
• Internet of Things (IoT) devices
• Satellite communication systems

Problems Solved

• Efficient use of uplink channels
• Coexistence of CDMA and OFDM signaling
• Optimization of communication protocols for UE devices

Benefits

• Enhanced communication reliability
• Increased network capacity
• Improved spectral efficiency

Original Abstract Submitted

Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may operate by asynchronously transmitting code division multiple access (CDMA) uplink signals to a network entity. The UE may transmit the CDMA signals via an uplink channel that may be shared with orthogonal frequency multiplexing (OFDM) signaling transmitted by one or more other UEs. The UE may indicate to the network entity a capability for communicating with CDMA waveforms and may use CDMA waveforms based on transmitting the indication. The UE may also receive one or more parameters associated with using the CDMA waveforms, and may use CDMA waveforms based on the one or more parameters. The uplink channel may be a random access channel (RACH) and may support RACH transmissions, or may be a data channel and support data transmissions.
