INACTIVE DIRECT TRANSMISSION FROM USER EQUIPMENT (UE) VIA RANDOM ACCESS CHANNEL (RACH) PROCEDURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441507 titled 'INACTIVE DIRECT TRANSMISSION FROM USER EQUIPMENT (UE) VIA RANDOM ACCESS CHANNEL (RACH) PROCEDURE

Simplified Explanation

The patent application discusses techniques for facilitating inactive state transmissions for a User Equipment (UE) device using a 4-step or 2-step inactive state RACH (Random Access Channel) process.

• The UE device includes communication circuitry and a processor.
• When a Radio Resource Control (RRC) inactive data transmission is determined, the UE device performs the following operations:

 * Transmits a message 1 (Msg1) or a message A (MsgA) preamble based on the RACH configuration.
 * Transmits a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) containing uplink (UL) data using configured resources.
 * Receives a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.

Potential applications of this technology:

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

Problems solved by this technology:

• Facilitates inactive state transmissions for UE devices, allowing them to conserve power and resources when not actively transmitting data.
• Enables efficient and reliable communication between UE devices and the network.

Benefits of this technology:

• Reduces power consumption and extends battery life for UE devices.
• Optimizes network resources by efficiently managing inactive state transmissions.
• Enhances overall system performance and reliability.

Original Abstract Submitted

Techniques discussed herein can facilitate inactive state transmissions for a User Equipment (UE) via a 4-step or 2-step inactive state RACH process. One example aspect is a UE device, comprising: communication circuitry; and a processor configured to perform operations comprising: in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission: transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission; transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.
