Abstract
Certain aspects of the present disclosure relate to methods and apparatus for providing quasi-colocation (QCL) signaling for reference signals (RS) and channels across scenarios involving multiple cells, such as coordinated multipoint (CoMP) scenarios in which multiple transmit receive points (TRPs) or integrated access and backhaul (IAB) nodes each have their own cell ID.
Claims30
A method for wireless communications by a user equipment (UE), comprising:
- obtaining quasi-colocation (QCL) information indicating QCL assumptions for one or more types of reference signals (RS) and channels associated with different cell identifications (IDs) including at least one non-serving cell ID;
- measuring the one or more types of RS;
- and
- processing one or more of the channels, based on the RS measurements and the QCL information.
A method for wireless communications by a network entity, comprising:
- generating quasi-colocation (QCL) information indicating QCL assumptions for one or more types of reference signals (RS) and channels associated with different cell identifications (IDs) including at least one non-serving cell ID;
- and
- transmitting the QCL information to at least one user equipment (UE) for use in processing one or more of the channels.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for obtaining quasi-colocation (QCL) information indicating QCL assumptions for one or more types of reference signals (RS) and channels associated with different cell identifications (IDs) including at least one non-serving cell ID;
- means for measuring the one or more types of RS;
- and
- means for processing one or more of the channels, based on the RS measurements and the QCL information.
