METHOD AND APPARATUS FOR RANDOM ACCESS TRANSMISSIONS AND RECEPTIONS IN A WIRELESS COMMUNICATION SYSTEM

Timelines for transmissions and receptions in random access. A method includes transmitting a first physical random access channel (PRACH) preamble in a first PRACH occasion (RO) using a first spatial setting and a second PRACH preamble in a second RO using a second spatial setting. The method further includes determining a first time window over a first number of symbols for reception of a first physical downlink control channel (PDCCH) scheduling reception of a first physical downlink shared channel (PDSCH) using a first transmission configuration indication (TCI) state and a second time window over a second number of symbols for reception of a second PDCCH scheduling reception of a second PDSCH using a second TCI state. The method further includes receiving the first PDCCH and the first PDSCH using the first TCI state or the second PDCCH and the second PDSCH using the second TCI state.
