PERSISTENT INDICATION OF ACKNOWLEDGEMENT RESOURCES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18223237 titled 'PERSISTENT INDICATION OF ACKNOWLEDGEMENT RESOURCES

Simplified Explanation

This patent application describes a method for configuring a user equipment (UE) to transmit control information to a communication network using uplink resources. Here are the key points:

  • The UE is configured with multiple collections of uplink resources for transmitting control information.
  • The UE receives a radio resource assignment from the communication network for receiving a downlink transmission.
  • The UE also receives an acknowledgement resource indication (ARI) which specifies one of the configured collections of uplink resources to be used for transmitting control information related to the downlink transmission.
  • The UE then transmits the control information to the base station using at least a subset of the indicated collection of uplink resources.
  • The indicated collection of uplink resources can consist of multiple selectable uplink resource sets.
  • The control information is transmitted on the uplink resource set that corresponds to the operational state of the communication network.


Original Abstract Submitted

A user equipment is configured with at least two collections of uplink resources to be used for transmitting control information to a communication network. The UE receives an assignment of radio resources to be used for receiving a downlink transmission from a base station of the communication network. The UE receives an acknowledgement resource indication, ARI, indicating one of the configured collections of uplink resources to be used for transmitting control information associated with the DL transmission. Further, the UE transmits the control information to the base station on at least a subset of the indicated collection of UL resources. In example embodiments, the indicated collection of uplink resources comprises a plurality of selectable uplink resource sets. The control information is transmitted on one of the uplink resource sets which corresponds to an operational state of the communication network.
