Enhancement of Message 3 for RACH Procedure - A simplified explanation of the abstract

This abstract first appeared for US patent application 17754450 titled 'Enhancement of Message 3 for RACH Procedure

Simplified Explanation

The abstract of this patent application describes a method for configuring a user equipment (UE) to receive message 3 (Msg3) transmissions in a wireless network. The UE receives a system information block (SIB) transmission, a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission, and the Msg2 transmission including an uplink (UL) grant for the Msg3 initial transmission. The UE determines the number of repetitions for the Msg3 initial transmission and the frequency hopping (FH) type and FH pattern based on the SIB transmission, DCI transmission, and Msg2 transmission.

• The UE receives SIB, DCI, and Msg2 transmissions.
• The UE determines the number of repetitions for the Msg3 initial transmission.
• The UE determines the FH type and FH pattern based on the SIB, DCI, and Msg2 transmissions.

Potential applications of this technology:

• Wireless communication systems
• Cellular networks
• Internet of Things (IoT) devices

Problems solved by this technology:

• Efficient configuration of UE for receiving Msg3 transmissions
• Optimal determination of repetitions and FH parameters
• Improved reliability and performance of wireless networks

Benefits of this technology:

• Enhanced communication efficiency
• Improved network reliability
• Increased data transmission capacity
• Better utilization of wireless resources

Original Abstract Submitted

A user equipment (UE) is configured to receive message 3 (Msg3) transmissions. The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.
