Abstract
Various aspects of the present disclosure relate to PSI based discard. In one aspect, a UE receive an indication from a base station. The indication indicates whether to activate PSI based discard for a DRB. In turn, the UE determines, based at least on the indication, whether to start a discard timer for data belonging to low importance data on the DRB. The discard timer is associated with the PSI based discard.
Claims20
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive an indication, from a network entity, indicating whether to activate Protocol Data Unit Set Importance (PSI) based discard for a Data Radio Bearer (DRB);
- and
- determine, based at least on the indication, whether to start a discard timer for data belonging to low importance data on the DRB, wherein the discard timer is associated with the PSI based discard.
A first network node for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the first network node to:
- transmit, to a second network node, first information associated with a configuration of Protocol Data Unit Set Importance (PSI) based discard for a Data Radio Bearer (DRB);
- and
- transmit the configuration of PSI based discard to a user equipment (UE).
A second network node for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the second network node to:
- receive, from a first network node, first information about a configuration of Protocol Data Unit Set Importance (PSI) based discard for a Data Radio Bearer (DRB);
- and
- transmit, to a user equipment (UE), an indication indicating whether to activate the PSI based discard.
A processor for wireless communication, comprising:
- a controller coupled with at least one memory and configured to cause the controller to:
- receive an indication, from a network entity, whether to activate Protocol Data Unit Set Importance (PSI) based discard for a Data Radio Bearer (DRB);
- and
- determine, based at least on the indication, whether to start a discard timer for data belonging to low importance data on the DRB, wherein the discard timer is associated with the PSI based discard.
