Methods and apparatus for sub-band full duplex (SBFD) Random Access Channel (RACH) configuration are described. In some embodiments, existing legacy Radio Resource Control (RRC) Information Elements (IEs), e.g., msg1-Frequency Start and msg-1 FDM, are re-used to signal RACH configuration to SBFD-aware UEs. In some embodiments, new RRC signaling IEs, e.g., msg1-FrequencyStartSBFD-r19, msg1-FDM-SBFD-19, ra-Msg1-RO-FrequencyOffsetSBFD-r19, and/or ra-RO-ScalingFactorSBFD-r19, are introduced specifically for SBFD RACH configuration for SBFD-aware UEs. The RACH configuration will be conveyed to the SBFD UEs via system information block 1 (SIB1), which is transmitted by a base station, e.g. gNB over the Physical Downlink Shared Channel (PDSCH). The UE reads the RACH configuration upon decoding SIB1 and then uses the information to determine resources to be used in a RACH access attempt.
