METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18151189 titled 'METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The present disclosure is about a wireless communication system and a method for transmitting and receiving Random Access (RA) preambles. The method includes the following steps:
- Transmitting an RA preamble on one Resource Opportunity (RO) among multiple ROs.
- The resource to which the RA preamble is transmitted includes a sub-interval index, a slot index, a symbol index, and a frequency resource index.
- After transmitting the RA preamble, monitoring Downlink Control Information (DCI) within a specific time window.
- The DCI includes an RA-identifier masked in a Cyclic Redundancy Check (CRC).
- Receiving an RA response corresponding to the DCI.
- One of the sub-interval index, slot index, symbol index, or frequency resource index is included in the payload of the DCI, while the rest are included in the RA-identifier.
Potential applications of this technology:
- Wireless communication systems, such as cellular networks.
- Internet of Things (IoT) devices that rely on wireless communication.
- Smart home devices that require wireless connectivity.
Problems solved by this technology:
- Efficient transmission and reception of RA preambles in a wireless communication system.
- Simplified identification and allocation of resources for RA preambles.
- Improved reliability and accuracy in receiving RA responses.
Benefits of this technology:
- Enhanced performance and efficiency in wireless communication systems.
- Reduced complexity and overhead in transmitting and receiving RA preambles.
- Improved reliability and success rate of RA procedures.
Original Abstract Submitted
The present disclosure relates to a wireless communication system. Specifically, the present disclosure relates to a method and an apparatus therefor, the method comprising the steps of: transmitting an RA preamble on one RO among a plurality of ROs, wherein a resource to which the RA preamble is transmitted includes the following elements, (a) a sub-interval index within a 10 ms interval, (b) a slot index within a sub-interval, (c) a symbol index within a slot, and (d) a frequency resource index; and after transmitting the RA preamble, monitoring DCI having an RA-identifier within a time window, the RA-identifier being masked in a CRC in the DCI, and receiving an RA response corresponding to the DCI, wherein one of (a) to (d) is included in a payload in the DCI, and the rest of (a) to (d) is included in the RA-identifier.
