Abstract: A control circuit of a wireless user equipment includes: a message generating circuit for generating a first and a second RRC (radio resource control) messages, and configuring corresponding first and second priorities; a message reordering circuit for comparing the first and second priorities. If the first priority is higher than the second priority, the message reordering circuit assigns the second RRC message in a message queue to have a transmission order after the first RRC message. Afterward, when the message generating circuit generates a third RRC message, the message generating circuit configures a third priority for the third RRC message. The message reordering circuit compares the first through the third priorities to rearrange transmission orders of RRC messages, and if the third priority is equal to the second priority, the message reordering circuit replaces the second RRC message in the message queue with the third RRC message.

Abstract: A control circuit of a wireless user equipment includes: a PDCP layer computing circuit for reading a PDCP SDU from a PDCP SDU buffer of a memory device of the wireless user equipment, and for generating a ciphered data based on the PDCP SDU; a RLC layer computing circuit for generating a RLC PDU based on the ciphered data; a MAC layer computing circuit for generating a MAC PDU based on the RLC PDU; and a channel encoding circuit for encoding the MAC PDU. The PDCP layer computing circuit directly transmits the ciphered data to the RLC layer computing circuit, the RLC layer computing circuit directly transmits the RLC PDU to the MAC layer computing circuit, and the MAC layer computing circuit directly transmits the MAC PDU to the channel encoding circuit, without buffering above data in any buffering circuit outside the control circuit.

Abstract: A control circuit of a wireless user equipment includes: a message generating circuit configured to operably generate a target RRC (radio resource control) messages to be transmitted to a communication station through a wireless communication circuit of the wireless user equipment, wherein the target RRC message is a predetermined-type RRC message; and a data control circuit coupled with the message generating circuit and configured to operably transmit the target RRC message to the communication station through the wireless communication circuit, and to retransmit the target RRC message to the communication station through the wireless communication circuit at least one more time before a negative acknowledgement (NACK) corresponding to the target RRC message is received by the wireless communication circuit.
