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:
- transmitting, by a wireless device, a preamble based on a first spatial filter;
- receiving an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a reference signal (RS);
- transmitting, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmitting, based on a second spatial filter associated with the RS, second repetitions of the TB repetitions.
5 more elements
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:
- transmit a preamble based on a first spatial filter;
- receive an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a reference signal (RS);
- transmit, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmit, based on a second spatial filter associated with the RS, second repetitions of the TB repetitions.

A system comprising:
- a base station;
- and
- 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:
- transmit, to the base station, a preamble based on a first spatial filter;
- receive, from the base station, an uplink grant indicating:
- transport block (TB) repetitions;
- and
- a reference signal (RS);
- transmit, based on the first spatial filter, first repetitions of the TB repetitions;
- and
- transmit, based on a second spatial filter associated with the RS, second repetitions of the TB repetitions.
