Patent Description:
Wireless communication technologies are moving the world toward an increasingly connected and networked society. High-speed and low-latency wireless communications rely on efficient network resource management and allocation between user equipment and wireless access network nodes (including but not limited to base stations). A new generation network is expected to provide high speed, low latency and ultra-reliable communication capabilities and fulfill the requirements from different industries and users.

For the 5th Generation mobile communication technology, a base station and/or a user equipment need to configure signal resource for a physical random access channel (PRACH). There are several issues/problems with the existing system for configuring signal resources for PRACH. For example, some of the issues/problems are associated with new subcarrier spacing (SCS) for a channel bandwidth being wider in high carrier frequency. Another of the issues/problems is what the configuration rules would be with the newly introduced PRACH SCS. Another of the issues/problems is how the base station and/or user equipment confirm the PRACH slot and number in response to a specific subcarrier spacing.
