RANDOM ACCESS CHANNEL PROCEDURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17873827 titled 'RANDOM ACCESS CHANNEL PROCEDURES
Simplified Explanation
The abstract of the patent application describes aspects related to random access channel procedures. It explains that if a user equipment (UE) fails to receive a random access channel (RACH) downlink message before the end of a random access window for a first RACH attempt, the UE may choose to make a second RACH attempt. The UE can determine if there are any remaining downlink symbols available during the random access window to receive the RACH downlink message. If not, the UE may retransmit a physical RACH (PRACH) preamble.
- The patent application focuses on random access channel procedures in wireless communication systems.
- It introduces the concept of a user equipment (UE) making multiple attempts to receive a random access channel (RACH) downlink message.
- The UE checks for remaining downlink symbols during the random access window to decide whether to proceed with a second RACH attempt.
- If no downlink symbols are available, the UE retransmits a physical RACH (PRACH) preamble.
Potential Applications:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
Problems Solved:
- Ensuring reliable reception of RACH downlink messages
- Improving the efficiency of random access channel procedures
- Reducing the likelihood of missed communication opportunities
Benefits:
- Increased success rate of RACH downlink message reception
- Enhanced overall performance of wireless communication systems
- Improved user experience with faster and more reliable connections
Original Abstract Submitted
Aspects relate to random access channel procedures. In some examples, if a user equipment (UE) has not successfully received a random access channel (RACH) downlink message prior to the end of a random access window for a first RACH attempt, the UE may elect to proceed with a second RACH attempt. For example, the UE may determine whether there are any remaining downlink symbols available during the random access window to receive the RACH downlink message. If not, the UE may retransmit a physical RACH (PRACH) preamble.
