Random Access in a Wireless Communication Network - A simplified explanation of the abstract

This abstract first appeared for US patent application 17917026 titled 'Random Access in a Wireless Communication Network

Simplified Explanation

The abstract describes a wireless device that determines if the resources configured for random access on a link can support a minimum gap requirement between the end of a transmission of a random access preamble and the start of a transmission of a payload. Based on this determination, the wireless device can either transmit the random access preamble and wait for a response before transmitting the payload, delay the random access until the resources support the minimum gap requirement, or choose a different link for random access.

  • The wireless device checks if the resources on a link can support a minimum gap requirement between random access preamble and payload transmission.
  • If the resources do not meet the requirement, the device can choose to wait for a response before transmitting the payload.
  • Alternatively, the device can delay random access until the resources support the minimum gap requirement.
  • The device also has the option to select a different link for random access.

Potential Applications

  • This technology can be applied in wireless communication systems, such as cellular networks, to optimize random access procedures.
  • It can improve the efficiency and reliability of random access transmissions in various wireless devices and networks.

Problems Solved

  • The technology addresses the issue of insufficient resources for random access transmissions, which can lead to collisions and reduced performance.
  • It solves the problem of wasted resources by allowing the device to wait for a response or select a different link when the minimum gap requirement is not met.

Benefits

  • By determining the availability of resources for random access, the technology reduces collisions and improves the overall performance of wireless communication systems.
  • It allows for more efficient use of resources by delaying random access or selecting alternative links when the minimum gap requirement is not met.
  • The technology enhances the reliability of random access transmissions by ensuring the proper timing between preamble and payload.


Original Abstract Submitted

A wireless device () determines that no resources configured for random access on a link support a minimum gap requirement of the wireless device (), where the minimum gap requirement is a minimum gap required in time between an end of a transmission of a random access preamble () and a start of a transmission of a payload (). Based on this determination, the wireless device either (i) transmits a random access preamble () using the resources configured for random access on the link, but waits to transmit a payload () until the wireless device () receives a random access response in response to the random access preamble (); (ii) delays random access on the link until resources configured for random access on the link support the minimum gap requirement of the wireless device (); or (iii) selects to perform random access on a different link.
