CONSTITUTION OF RATE-SPLITTING MULTIPLE-ACCESS USER EQUIPMENT GROUP - A simplified explanation of the abstract
This abstract first appeared for US patent application 18150076 titled 'CONSTITUTION OF RATE-SPLITTING MULTIPLE-ACCESS USER EQUIPMENT GROUP
The abstract describes a technique for rate-splitting multiple access (RSMA) for a user equipment (UE) group, where messages are split into common and private messages for transmission to a group of receiver UEs (Rx UEs).
- Transmitting an indication to a group of Rx UEs that the Tx UE will use RSMA for transmission.
- Splitting individual messages into common and private messages.
- Combining common messages and transmitting them using a first precoder.
- Transmitting private messages using separate precoders.
Potential Applications: - Wireless communication systems - Mobile networks - Internet of Things (IoT) devices
Problems Solved: - Efficient transmission to multiple UEs in a group - Optimizing spectrum usage - Enhancing communication reliability
Benefits: - Increased throughput - Reduced interference - Improved system capacity
Commercial Applications: Title: "Enhanced Wireless Communication Systems with RSMA" This technology can be utilized in 5G networks, IoT devices, and smart city applications, improving overall network performance and reliability.
Questions about RSMA: 1. How does RSMA improve communication efficiency in wireless networks? RSMA improves communication efficiency by splitting messages into common and private messages, optimizing transmission to multiple UEs in a group.
2. What are the advantages of using separate precoders for transmitting private messages in RSMA? Using separate precoders for private messages in RSMA helps reduce interference and improve overall system capacity.
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for rate-splitting multiple access (RSMA) for a user equipment (UE) group. An example method includes transmitting, to a group of receiver UEs (Rx UEs), an indication that the Tx UE will transmit to the group of Rx UEs using rate splitting multiple access (RSMA), and transmitting to the group using RSMA, wherein transmitting to the group using RSMA comprises: splitting individual messages intended for individual Rx UEs in the group into common messages and private messages, combining the common messages, transmitting the combined common messages using a first precoder, and transmitting the private messages using separate precoders.
