Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, based at least in part on transmitting information indicating a UE capability for uplink frequency shift configuration, quasi-co-location (QCL) information associated with an uplink transmission control indicator (TCI) state; determine an uplink frequency shift configuration for a sounding reference signal (SRS) based at least in part on the QCL information associated with the uplink TCI state; and transmit the SRS based at least in part on the uplink frequency shift configuration. Numerous other aspects are provided.
Claims35
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, based at least in part on the UE transmitting information indicating a UE capability for Doppler shift modulation, quasi-co-location (QCL) information associated with an uplink transmission control indicator (TCI) state;
- and
- transmitting a sounding reference signal (SRS) with or without Doppler shift modulation based on the QCL information.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- a transceiver;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive, via the transceiver and based at least in part on the UE transmitting information indicating a UE capability for Doppler shift modulation, quasi-co-location (QCL) information associated with an uplink transmission control indicator (TCI) state;
- and
- transmit, via the transceiver, a sounding reference signal (SRS) with or without Doppler shift modulation based on the QCL information.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), instruct the one or more processors to:
- receive, based at least in part on the UE transmitting information indicating a UE capability for Doppler shift modulation, quasi-co-location (QCL) information associated with an uplink transmission control indicator (TCI) state;
- and
- transmit a sounding reference signal (SRS) with or without Doppler shift modulation based on the QCL information.
An apparatus for wireless communication, comprising:
- means for receiving, based at least in part on the apparatus transmitting information indicating a capability for Doppler shift modulation, quasi-co-location (QCL) information associated with an uplink transmission control indicator (TCI) state;
- and
- means for transmitting a sounding reference signal (SRS) with or without Doppler shift modulation based on the QCL information.
