PHYSICAL RANDOM ACCESS CHANNEL (PRACH) RECEIVER FOR DETERMINING CELLS IN WHICH A PREAMBLE HAS BEEN TRANSMITTED - A simplified explanation of the abstract
This abstract first appeared for US patent application 18281455 titled 'PHYSICAL RANDOM ACCESS CHANNEL (PRACH) RECEIVER FOR DETERMINING CELLS IN WHICH A PREAMBLE HAS BEEN TRANSMITTED
Simplified Explanation
The abstract describes a method for determining cells in which a preamble has been transmitted, involving obtaining sample sets associated with different cells, combining the sample sets, forming candidate sets based on the combined samples, and using these candidate sets to determine which cells transmitted the preamble.
- The method involves obtaining N sample sets, each associated with a different cell.
- The sample sets are combined to create a first combined set of samples.
- Candidate sets of tuples are formed based on the combined samples and an initial set of tuples.
- The candidate sets are used to determine which cells transmitted the preamble.
Potential Applications
This technology could be applied in:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
Problems Solved

What are the specific steps involved in determining which cells transmitted the preamble?
The specific steps involved in determining which cells transmitted the preamble include obtaining N sample sets associated with different cells, combining the sample sets to create a first combined set of samples, forming candidate sets of tuples based on the combined samples and an initial set of tuples, and using these candidate sets to determine which cells transmitted the preamble.
How does this method improve the efficiency of identifying cells where a preamble has been transmitted?
This method improves the efficiency of identifying cells where a preamble has been transmitted by combining sample sets from different cells, forming candidate sets based on these combined samples, and using these candidate sets to accurately determine which cells transmitted the preamble. This approach helps in reducing false positives and improving the overall accuracy of preamble detection in wireless communication systems.
Original Abstract Submitted
A method () for determining cells in which a preamble has been transmitted. The method includes obtaining (s) N sample sets, wherein each one of the N sample sets comprises a set of M samples and each one of the N sample sets is associated with a different cell included in a set of N cells. The method also includes adding (s) the N sample sets to create a first combined set of samples comprising M samples. The method also includes forming (s) a first candidate set of one or more tuples based on the first combined set of samples and an initial set of tuples comprising a plurality of tuples, wherein each tuple comprises a candidate preamble and a candidate delay, and wherein each candidate preamble comprises a set of samples. The method further includes using (s) the first candidate set of one or more tuples to determine, for each cell included in the set of cells, whether a preamble included in the first candidate set of tuples was transmitted in the cell.
