PRIORITIZATION BETWEEN SR AND HARQ-ACK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17918073 titled 'PRIORITIZATION BETWEEN SR AND HARQ-ACK

Simplified Explanation

The patent application describes a method for prioritizing between Scheduling Requests (SRs) and Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information in wireless communication devices. The method involves prioritizing or multiplexing SR occasions on one Physical Uplink Control Channel (PUCCH) resource and HARQ-ACK information on another PUCCH resource, even if they partially overlap in time. This improves latency for uplink communication without increasing downlink load or inter-cell interference.

  • The method prioritizes or multiplexes SR occasions and HARQ-ACK information on separate PUCCH resources.
  • The SR occasions and HARQ-ACK information can partially overlap in time.
  • This approach reduces unnecessary re-transmissions, improving latency for uplink communication.
  • The method does not introduce higher downlink load or inter-cell interference.

Potential Applications

  • This technology can be applied in wireless communication systems to improve the efficiency and latency of uplink communication.
  • It can be used in various wireless devices, such as smartphones, tablets, and IoT devices, to enhance their overall performance.

Problems Solved

  • The method solves the problem of latency in uplink communication by prioritizing SR occasions and HARQ-ACK information.
  • It avoids unnecessary re-transmissions, reducing latency without increasing downlink load or inter-cell interference.

Benefits

  • The method improves the efficiency and latency of uplink communication in wireless systems.
  • It provides a more reliable and faster communication experience for users of wireless devices.
  • The approach reduces unnecessary re-transmissions, saving network resources and improving overall system performance.


Original Abstract Submitted

Systems and methods are disclosed herein that relate to prioritization of Scheduling Requests (SRs) and Hybrid Automatic Repeat Request (HARQ) feedback information. In one embodiment, a method performed by a wireless communication device for prioritization between a Scheduling Request (SR) occasion and Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information scheduled on overlapping Physical Uplink Control Channel (PUCCH) resources comprising prioritizing or multiplexing a SR occasion on a first PUCCH resource and HARQ-ACK information on a second PUCCH resource, the first PUCCH resource and the second PUCCH resource at least partially overlapping in time. In this manner, latency improvement for uplink (UL) is provided without introducing higher downlink (DL) load nor inter-cell interference since unnecessary re-transmissions can be avoided.
