Wireless communication method and user equipment for performing transmission in rrc_inactive state

A wireless communication method performed by a User Equipment (UE) for performing transmissions in a Radio Resource Control (RRC)_INACTIVE state, the wireless communication method comprising:

• receiving, in an RRC_CONNECTED state, an RRC release message including first information and second information, the first information including at least one Logical Channel Prioritization (LCP) restriction, and the second information including one or more Configured Grant (CG) configurations;
• transitioning from the RRC_CONNECTED state to the RRC_INACTIVE state in response to receiving the RRC release message;
• determining, after transitioning to the RRC_INACTIVE state, that data from a Logical Channel (LCH) corresponding to the at least one LCP restriction becomes available for Uplink (UL) transmission;
• determining whether to transmit the data in the RRC_INACTIVE state according to whether any of the one or more CG configurations meets the at least one LCP mapping restriction;
• and
• in a case that a CG configuration of the one or more CG configurations meets the at least one LCP mapping restriction, transmitting the data through a set of Physical Uplink Shared Channels (PUSCHs) determined by the CG configuration of the one or more CG configurations.

A User Equipment (UE) for performing transmissions in a Radio Resource Control (RRC)_INACTIVE state, the UE comprising:

• a receiver;
• a transmitter;
• at least one processor coupled to the receiver and the transmitter;
• and
• at least one memory coupled to the at least one processor, wherein the at least one memory stores at least one computer-executable program that, when executed by the at least one processor, causes the UE to:
• receive, in an RRC_CONNECTED state, by the receiver, an RRC release message including first information and second information, the first information including at least one Logical Channel Prioritization (LCP) restriction, and the second information including one or more Configured Grant (CG) configurations;
• transition from the RRC_CONNECTED state to the RRC_INACTIVE state in response to receiving the RRC release message;
• determine, after transitioning to the RRC_INACTIVE state, that data from a Logical Channel (LCH) corresponding to the at least one LCP restriction becomes available for Uplink (UL) transmission;
• determine whether to transmit the data in the RRC_INACTIVE state according to whether any of the one or more CG configurations meets the at least one LCP mapping restriction;
• and
• in a case that a CG configuration of the one or more CG configurations meets the at least one LCP mapping restriction, transmit, by the transmitter, the data through a set of Physical Uplink Shared Channels (PUSCHs) determined by the CG configuration of the one or more CG configurations.
