SYSTEMS AND METHODS FOR PROVIDING RANDOM ACCESS CHANNEL (RACH) SIGNALING TO USER EQUIPMENT (UE) DURING INACTIVE DIRECT TRANSMISSIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441528 titled 'SYSTEMS AND METHODS FOR PROVIDING RANDOM ACCESS CHANNEL (RACH) SIGNALING TO USER EQUIPMENT (UE) DURING INACTIVE DIRECT TRANSMISSIONS

Simplified Explanation

The patent application discusses techniques for facilitating inactive state transmissions for a Base Station (BS) using a 4-step or 2-step inactive state RACH process. Here is a simplified explanation of the abstract:

• The patent application describes a method for a Base Station (BS) to transmit data in an inactive state.
• The BS receives a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for an inactive data transmission.
• The BS then receives a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) containing uplink (UL) data through configured resources.
• In response to the Msg3 or the MsgA PUSCH, the BS transmits a message 4 (Msg4) or a message B (MsgB) via the communication circuitry.

Potential applications of this technology:

• This technology can be applied in cellular networks to improve the efficiency of data transmission from Base Stations.
• It can be used in 5G networks to enhance the performance of inactive state transmissions.
• The techniques described in the patent application can be implemented in various wireless communication systems to optimize resource allocation and improve overall network capacity.

Problems solved by this technology:

• The technology addresses the challenge of transmitting data efficiently in an inactive state, where the Base Station is not actively communicating with user devices.
• It solves the problem of optimizing resource allocation for inactive state transmissions, ensuring that the available resources are utilized effectively.

Benefits of this technology:

• By using the 4-step or 2-step inactive state RACH process, this technology enables more efficient data transmission during inactive periods, leading to improved network performance.
• It allows for better resource utilization, reducing congestion and improving overall network capacity.
• The techniques described in the patent application can enhance the reliability and stability of data transmission in wireless communication systems.

Original Abstract Submitted

Techniques discussed herein can facilitate inactive state transmissions for a Base Station (BS) via a 4-step or 2-step inactive state RACH process. One example aspect is a BS comprising: communication circuitry; and one or more processors communicatively coupled to the communication circuitry and configured to: receive, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for a Radio Resource Control (RRC) inactive data transmission; receive, via the communication circuitry, a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and transmit, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.
