REPETITION OF PRACH PREAMBLE TRANSMISSION FOR UES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18146229 titled 'REPETITION OF PRACH PREAMBLE TRANSMISSION FOR UES

Simplified Explanation

The patent application describes apparatuses and methods for transmitting and receiving physical random access channel (PRACH) preambles. The method involves a user equipment (UE) receiving a physical downlink shared channel (PDSCH) that contains a system information block (SIB). The SIB includes information about two different transmission configuration indication (TCI) states, each providing a different set of quasi-collocation (QCL) properties. The method further involves the UE transmitting a first PRACH according to the properties of the first TCI state and a second PRACH according to the properties of the second TCI state.

  • The patent application focuses on physical random access channel (PRACH) preamble transmissions or receptions.
  • The method involves a user equipment (UE) receiving a physical downlink shared channel (PDSCH) that contains a system information block (SIB).
  • The SIB includes information about two different transmission configuration indication (TCI) states.
  • Each TCI state provides a different set of quasi-collocation (QCL) properties.
  • The method further involves the UE transmitting a first PRACH according to the properties of the first TCI state and a second PRACH according to the properties of the second TCI state.

Potential Applications

  • This technology can be applied in wireless communication systems, particularly in the context of physical random access channel (PRACH) transmissions or receptions.
  • It can be used in various wireless devices such as smartphones, tablets, IoT devices, and other communication devices.

Problems Solved

  • The technology addresses the need for efficient and reliable physical random access channel (PRACH) preamble transmissions or receptions.
  • It solves the problem of managing different transmission configuration indication (TCI) states and their associated quasi-collocation (QCL) properties.
  • The method ensures that the user equipment (UE) can transmit PRACH preambles according to the appropriate TCI state, based on the system information block (SIB) received.

Benefits

  • The technology allows for improved performance and reliability of physical random access channel (PRACH) transmissions or receptions.
  • By providing different transmission configuration indication (TCI) states with distinct quasi-collocation (QCL) properties, the method enables efficient utilization of resources and better management of interference.
  • The method ensures that the user equipment (UE) can adapt its PRACH transmission based on the system information block (SIB) received, optimizing the overall communication system.


Original Abstract Submitted

Apparatuses and methods for physical random access channel (PRACH) preamble transmissions or receptions. A method of a UE includes receiving a physical downlink shared channel (PDSCH) that provides a system information block (SIB). The SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties. The method further includes transmitting a first PRACH according to the first TCI state and a second PRACH according to the second TCI state.
