MULTIPLEXING TRANSMIT POWER CONTROL INFORMATION AND SIDELINK DATA TRAFFIC - A simplified explanation of the abstract
This abstract first appeared for US patent application 17391461 titled 'MULTIPLEXING TRANSMIT POWER CONTROL INFORMATION AND SIDELINK DATA TRAFFIC
Simplified Explanation
Abstract
This patent application describes a system for wireless communication that enables transmit power control (TPC) for user equipment (UE) sidelink communications. TPC information is provided by a first UE that receives transmissions from a second UE, and this information is multiplexed with sidelink data traffic in a sidelink communication between the UEs. The TPC information includes a TPC indicator and one or more TPC messages for providing TPC commands for the sidelinks.
- Closed-loop transmit power control (TPC) for user equipment (UE) sidelink communications
- TPC information is provided by a first UE receiving transmissions from a second UE
- TPC information is multiplexed with sidelink data traffic in a sidelink communication between UEs
- TPC information includes a TPC indicator and one or more TPC messages for providing TPC commands for the sidelinks
- Sidelink data traffic may include data-only traffic, such as semi-persistent scheduled (SPS) data traffic, decoupled from accompanying sidelink control information (SCI)
Potential Applications
- Wireless communication systems
- User equipment (UE) sidelink communications
Problems Solved
- Lack of closed-loop transmit power control (TPC) for UE sidelink communications
- Difficulty in providing TPC information for sidelinks
- Inability to multiplex TPC information with sidelink data traffic
Benefits
- Improved transmit power control for UE sidelink communications
- Efficient multiplexing of TPC information with sidelink data traffic
- Enhanced performance and reliability of wireless communication systems
Original Abstract Submitted
This disclosure provides systems, methods, and devices for wireless communication that support closed-loop transmit power control (TPC) for user equipment (UE) sidelink communications. TPC information may be provided, by a first UE receiving transmissions from a second UE, with respect to a sidelink implemented between the UEs. TPC information may be multiplexed with sidelink data traffic in a sidelink communication between UEs. The TPC information may include a TPC indicator and one or more TPC messages for providing TPC commands with respect to one or more sidelinks. The sidelink data traffic of some examples may include data-only traffic, such as semi-persistent scheduled (SPS) data traffic, that is decoupled from accompanying sidelink control information (SCI). Other aspects and features are also claimed and described.
