Abstract
Aspects relate to mechanisms for a UE to indicate the supported beam combining types to the network based on the beamforming architecture of the UE. In some examples, the UE may be configured to transmit transmission configuration indicator (TCI) state information to a network entity. The TCI state information may include, for example, a single TCI state or multiple TCI states based on a UE capability to support RF beam combining, IF beam combining, and/or BB beam combining of beamformed signals across one or more antenna modules of the UE. The UE may further receive a downlink transmission from the network entity using one or more selected TCI states based on the TCI state information.
Claims30
An apparatus for wireless communication at a user equipment (UE), the apparatus comprising:
- one or more antenna modules;
- one or more memories;
- and
- one or more processors coupled to the one or more memories and the one or more antenna modules, the one or more processors being configured to:
- transmit transmission configuration indicator (TCI) state information to a network entity, the TCI state information comprising at least one of a single TCI state or multiple TCI states based on the UE supporting one or more of radio frequency (RF) combining, intermediate frequency (IF) combining, or baseband (BB) combining of beamformed signals across the one or more antenna modules;
- and
- receive a downlink transmission from the network entity, the downlink transmission using one or more selected TCI states based on the TCI state information.
A method operable at a user equipment (UE), the method comprising:
- transmitting transmission configuration indicator (TCI) state information to a network entity, the TCI state information comprising at least one of a single TCI state or multiple TCI states based on the UE supporting one or more of radio frequency (RF) combining, intermediate frequency (IF) combining, or baseband (BB) combining of beamformed signals across one or more antenna modules of the UE;
- and
- receiving a downlink transmission from the network entity, the downlink transmission using one or more selected TCI states based on the TCI state information.
An apparatus for wireless communication at a network entity, the apparatus comprising:
