Abstract
Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI).
Claims30
A method for wireless communications by a network entity, comprising:
- configuring a user equipment (UE) with a group of component carriers (CCs);
- receiving, from the UE, a report of a failed uplink beam on one of the CCs in the group;
- determining the same uplink beam has failed across other CCs in the group;
- and
- taking one or more actions to apply one or more new uplink beams on the CCs in the group.
2 more elements
A method for wireless communications by a user equipment (UE), comprising:
- receiving, from a network entity, signaling configuring the UE with a group of component carriers (CCs);
- detecting a failed uplink beam on one of the CCs in the group;
- reporting the failed uplink beam to the network entity;
- and
- taking one or more actions to apply one or more new uplink beams on the CCs in the group.
2 more elements
An apparatus for wireless communications by a network entity, comprising:
- a transmitter configured to signal, to a user equipment (UE), a configuration of a group of component carriers (CCs);
- a receiver configured to receive, from the UE, a report a failed uplink beam on one of the CCs in the group;
- and
- at least one processor configured to determine the same uplink beam has failed across other CCs in the group and take one or more actions to apply one or more new uplink beams on the CCs in the group.
1 more element
An apparatus for wireless communications by a user equipment (UE), comprising:
- a receiver configured to receive, from a network entity, signaling configuring the UE with a group of component carriers (CCs);
- and
- at least one processor configured to detect a failed uplink beam on one of the CCs in the group, report the failed uplink beam to the network entity, and take one or more actions to apply one or more new uplink beams on the CCs in the group.
