Abstract
Apparatuses and methods for physical random access channel (PRACH) preamble transmissions or receptions. A method of a UE includes receiving a physical downlink shared channel (PDSCH) that provides a system information block (SIB). The SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties. The method further includes transmitting a first PRACH according to the first TCI state and a second PRACH according to the second TCI state.

A method comprising:
- receiving a physical downlink shared channel (PDSCH) that provides a system information block (SIB), wherein the SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties;
- and
- transmitting a first physical random access channel (PRACH) according to the first TCI state and a second PRACH according to the second TCI state.
A user equipment (UE) comprising:
- a transceiver configured to:
- receive a physical downlink shared channel (PDSCH) that provides a system information block (SIB), wherein the SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties;
- and
- transmit a first physical random access channel (PRACH) according to the first TCI state and a second PRACH according to the second TCI state.
A base station comprising:
- a transceiver configured to:
- transmit a physical downlink shared channel (PDSCH) that provides a system information block (SIB), wherein the SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties;
- and
- receive a first physical random access channel (PRACH) according to the first TCI state and a second PRACH according to the second TCI state.
