Abstract
A wireless device transmits a preamble based on a first spatial filter. The wireless device receives an uplink grant indicating transport block (TB) repetitions and a reference signal (RS). The wireless device transmits, based on the first spatial filter, first repetitions of the TB repetitions. The wireless device transmits, based on a second spatial filter associated with the RS, second repetitions of the TB repetitions.
Claims20
A method comprising:
- determining, by a wireless device, a preamble based on an association of the preamble with a first reference signal (RS) associated with a first spatial filter;
- transmitting the preamble based on the first spatial filter;
- receiving an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a second RS, wherein the second RS is associated with a transmission configuration indication (TCI) state and is used for quasi colocation information of the TCI state;
- transmitting, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmitting, based on a second spatial filter associated with the second RS, second repetitions of the TB repetitions.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- determine a preamble based on an association of the preamble with a first reference signal (RS) associated with a first spatial filter;
- transmit the preamble based on the first spatial filter;
- receive an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a second RS, wherein the second RS is associated with a transmission configuration indication (TCI) state and is used for quasi colocation information of the TCI state;
- transmit, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmit, based on a second spatial filter associated with the second RS, second repetitions of the TB repetitions.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
- determine a preamble based on an association of the preamble with a first reference signal (RS) associated with a first spatial filter;
- transmit the preamble based on the first spatial filter;
- receive an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a second RS, wherein the second RS is associated with a transmission configuration indication (TCI) state and is used for quasi colocation information of the TCI state;
- transmit, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmit, based on a second spatial filter associated with the second RS, second repetitions of the TB repetitions.
