Abstract
Certain aspects of the present disclosure provide techniques and apparatuses for managing radio bearers during traffic congestion in a wireless communications networks having relays. According to certain aspects, a donor base station may detect traffic congestion on a Un radio bearer configured to interface between the relay node and the donor base station, where the Un radio bearer carries a plurality of Uu bears configured to interface between the relay node and at least one user equipment (UE). According to certain aspects, the donor base station may take one or more actions to trigger removal of at least one of the Uu bearers carried on the Un bearer.
Claims24
A method for operating a donor base station having a first plurality of radio bearers (RBs) that interface with a relay node, the method comprising:
- determining traffic congestion on the first plurality of RBs;
- and
- taking one or more actions to trigger removal of at least one of a second plurality of RBs that interface between the relay node and at least one user equipment (UE).
A donor base station having a first plurality of radio bearers (RBs) that interface with a relay node, the donor base station comprising:
- a traffic monitor component configured to determine traffic congestion on the first plurality of RBs;
- and
- a radio bearer manager component configured to take one or more actions to trigger removal of at least one of a second plurality of RBs that interface between the relay node and at least one user equipment (UE).
An apparatus for wireless communications having a first plurality of radio bearers (RBs) that interface with a relay node, comprising:
- means for determining traffic congestion on the first plurality of RBs;
- and
- means for taking one or more actions to trigger removal of at least one of a second plurality of RBs that interface between the relay node and at least one user equipment (UE).
A computer program product comprising a computer readable medium having instructions for operating a donor base station having a first plurality of radio bearers (RBs) that interface with a relay node stored thereon, the instructions executable by one or more processors for:
- determining traffic congestion on the first plurality of RBs;
- and
- taking one or more actions to trigger removal of at least one of a second plurality of RBs that interface between the relay node and at least one user equipment (UE).
