RACH OCCASION REPETITION AND PRACH FORMAT SELECTION BASED ON DEVICE TYPE IN NTN - A simplified explanation of the abstract

This abstract first appeared for US patent application 18270393 titled 'RACH OCCASION REPETITION AND PRACH FORMAT SELECTION BASED ON DEVICE TYPE IN NTN

Simplified Explanation

The abstract of the patent application describes a method for selecting PRACH configurations for different UEs in a network, allowing for efficient RACH occasion repetition and PRACH format selection.

• The base station determines PRACH configurations for different UEs based on beam information.
• The base station transmits indications of the PRACH configurations to the UEs.
• UEs select PRACH configurations based on the received indications and initiate RACH procedures accordingly.

Potential Applications

This technology could be applied in wireless communication systems, such as 5G networks, to improve random access procedures and optimize resource allocation.

Problems Solved

1. Efficient selection of PRACH configurations for different UEs. 2. Reduction of collisions and interference in random access procedures.

Benefits

1. Improved network efficiency. 2. Enhanced user experience with faster access to resources. 3. Better utilization of network resources.

Potential Commercial Applications

Optimized random access procedures can benefit telecommunications companies by improving network performance and customer satisfaction, leading to potential cost savings and increased revenue.

Possible Prior Art

Prior art in the field of wireless communication systems may include methods for random access control and resource allocation in networks. Research on beamforming techniques and PRACH configurations could also be relevant.

How does this technology impact network latency?

This technology could potentially reduce network latency by optimizing random access procedures and resource allocation, but the exact impact would depend on various network conditions and implementations.

What are the potential security implications of this technology?

Implementing PRACH configurations based on beam information could raise security concerns related to potential eavesdropping or unauthorized access. It would be important to address these issues through encryption and authentication mechanisms.

Original Abstract Submitted

RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.
