METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18045083 titled 'METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The patent application describes a method for performing a random access procedure in a communication system. Here are the key points:
- The method involves selecting a Synchronization Signal Block (SSB) with a strong signal power.
- A contention-based random access preamble is transmitted corresponding to the selected SSB.
- A Random Access Response (RAR) is received, containing a Media Access Control Protocol Data Unit (MAC PDU) indicating the size of uplink resource allocation.
- A message (Msg3) is transmitted including the MAC PDU to determine if contention is resolved.
- If contention is not resolved, a contention-free random access procedure is performed.
Potential applications of this technology:
- This method can be applied in various communication systems, such as cellular networks, to improve random access procedures.
- It can enhance the efficiency and reliability of random access in wireless communication, leading to better overall system performance.
Problems solved by this technology:
- Random access procedures in communication systems can be prone to contention and interference, leading to delays and inefficiencies.
- This method helps to resolve contention issues by selecting SSBs with stronger signal power and performing contention-free random access when necessary.
Benefits of this technology:
- By selecting SSBs with higher signal power, the method improves the chances of successful random access and reduces contention.
- The use of contention-free random access procedures when contention is not resolved further enhances the efficiency of the system.
- Overall, this method improves the reliability, speed, and efficiency of random access procedures in communication systems.
Original Abstract Submitted
Provided is a method of performing a random access procedure, the method including: selecting, from among a plurality of Synchronization Signal Blocks (SSBs), a first SSB that exceeds a threshold value of signal power; transmitting a contention-based random access preamble corresponding to the first SSB; receiving a first Random Access Response (RAR) corresponding to the contention-based random access preamble; obtaining a first Media Access Control Protocol Data Unit (MAC PDU) corresponding to a size of uplink (UL) resource allocation in the first RAR; transmitting a message3 (Msg3) including the first MAC PDU; determining, by transmitting the Msg3, whether contention is resolved; and when the contention is not resolved, performing a contention-free random access procedure.
