Abstract
Certain aspects of the present disclosure provide techniques for signaling information regarding beams used for data and control transmissions to a receiving entity.
Claims32
A method for wireless communication by a transmitting entity, comprising:
- signaling, to a receiving entity, quasi co-location (QCL) information regarding a relationship between beams used for data and control transmissions to the receiving entity, wherein the QCL information comprises spatial information including an indication of a beam shape associated with at least one of the beams or with receive beamforming for receiving the data and control transmissions;
- and
- sending the data and control transmissions using the beams.
A method for wireless communication by a receiving entity, comprising:
- receiving, from a transmitting entity, quasi co-location (QCL) information regarding a relationship between beams used for data and control transmissions to the receiving entity, wherein the QCL information comprises spatial information including an indication of a beam shape associated with at least one of the beams or with receive beamforming for receiving the data and control transmissions;
- and
- processing the data and control transmissions, based on the received QCL information.
An apparatus for wireless communication, comprising:
- at least one processor configured to obtain quasi co-location (QCL) information regarding a relationship between beams used for data and control transmissions to a receiving entity, wherein the QCL information comprises spatial information including an indication of a beam shape associated with at least one of the beams or with receive beamforming for receiving the data and control transmissions;
- and
- a transmitter configured to signal the QCL information to the receiving entity and to send the data and control transmissions using the beams.
An apparatus for wireless communication, comprising:
- a receiver configured to receive, from a transmitting entity, quasi co-location (QCL) information regarding a relationship between beams used for data and control transmissions to the apparatus, wherein the QCL information comprises spatial information including an indication of a beam shape associated with at least one of the beams or with receive beamforming for receiving the data and control transmissions;
- and
- at least one processor configured to process the data and control transmissions, based on the received QCL information.
