摘要： Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

摘要： Methods and apparatus for random access in multicarrier wireless communications are disclosed. Methods and apparatus are provided for physical random access channel (PRACH) resource signaling, PRACH resource handling, preamble and PRACH resource selection, random access response (RAR) reception, preamble retransmission, and transmission and reception of subsequent messages. A method for maintaining an allowed multicarrier uplink (UL) random access channel (RACH) configuration set by adding an UL carrier to the allowed RACH configuration set provided that a triggering event occurs and performing a random access (RA) procedure using the allowed RACH configuration set. A method for sending data in multicarrier wireless communications by determining a set of available UL carriers and selecting an UL carrier from the set of available UL carriers.

摘要： A WTRU may send a registration message to a core network (CN) that is associated with a first cell of a first radio access technology (RAT) and a second cell of a second RAT. The WTRU may receive, on the first cell of the first RAT with a first radio resource control (RRC) protocol, a RRC reconfiguration message that includes information for communications with the second cell of the second RAT. The first cell of the first RAT may be utilized for mobility management and a second RRC protocol may be utilized with the second cell of the second RAT.

摘要： Systems, methods, and instrumentalities are disclosed such that a network (e.g., a radio access network, RAN, node) may provide a wireless transmit/receive unit (WTRU) with a service-based network access for a new service. The RAN node may comprise a receiver, a transmitter, and a processor operatively coupled to the receiver and the transmitter. The receiver may be configured to receive a request message from the WTRU. The request message may indicate service-based network access information. The processor may be configured to select a service node belonging to a core network based on information in the request message. The transmitter may be configured to send a response message to the WTRU. The response message may indicate accepted service-based network access information, wherein the accepted service-based network access information is associated with at least one public land mobile network (PLMN) identifier (ID).
