Assignee: APPLE INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 15:
16. A Base Station (BS) comprising:
communication circuitry; and
one or more processors communicatively coupled to the communication circuitry and configured to:
configure a dedicated preamble group for a Radio Resource Control (RRC) inactive data transmission wherein the dedicated preamble group is configured for a user equipment (UE) that remains in an RRC inactive state after a Random Access Channel (RACH) procedure;
receive, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a RACH configuration of the RACH procedure for the RRC inactive data transmission, wherein the RACH configuration is a dedicated RACH configuration for the RRC inactive data transmission and the Msg1 or MsgA preamble is one of the dedicated preamble group, wherein the Msg1 or the MsgA preamble is initiated by the UE;
receive, via the communication circuitry, the RRC inactive data transmission, wherein the RRC inactive data transmission is a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data; and
transmit, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.
