PROBLEM TO BE SOLVED: To disclose a variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters.SOLUTION: A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) "one sided RLC re-establishment" is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established.

PROBLEM TO BE SOLVED: To solve the problem that setting states of an RLC PDU size of a fixed length or a variable length may become inconsistent between an RNC and a Node-B.SOLUTION: The base station device receives a RADIO LINK ADDITION REQUEST message from a control device. The RADIO LINK ADDITION REQUEST message includes DL RLC PDU size format information and HS-DSCH MAC-d PDU Size Format information.

PROBLEM TO BE SOLVED: To improve response in both-way communication in communication using a communication protocol in which a congestion window size is controlled depending on the number of confirmation responses.SOLUTION: A communication device for executing a communication protocol for controlling a window size for determining the number of communication segments transmissible in a period from transmission of a communication segment to reception of a confirmation response from a reception side device in response to the communication segment, depending on the number of confirmation responses comprises: a reception unit for receiving a confirmation response; and a determination unit for setting a communication segment length on the basis of delay time required from start of transmission of a data block which is obtained using a value of a communication index, is divided into a plurality of communication segments, and is sequentially transmitted to completion of reception of a confirmation response from the reception side device.

PROBLEM TO BE SOLVED: To provide alternate approaches to multiplexing EU data.SOLUTION: A method for multiplexing data for an enhanced uplink (EU) channel implemented by a wireless transmit/receive unit (WTRU) comprises the steps of: receiving at least one serving grant and at least one non-scheduled grant; multiplexing data from MAC-d flows into a MAC-e PDU, where a data multiplexing limit is at least based on an E-TFC size and a size on the basis of the at least one serving grant and the at least one non-scheduled grant; selecting an E-TFC for transmission of the MAC-e PDU, where the selected E-TFC is the smallest E-TFC that supports the multiplexed data; and transmitting the MAC-e PDU on the basis of the selected E-TFC over an EU channel.

PROBLEM TO BE SOLVED: To perform data communication with a data size of fixed length or variable length in flow control.SOLUTION: A mobile communication system includes a controller and a base station device. Data communication between the controller and the base station device is performed with a data size of fixed length and a data size of variable length. The controller transmits information indicating whether the data size of data information is fixed length or variable length. The base station device receives the information from the controller.
