摘要:
A method and apparatus for radio link synchronization and power control in CELL_FACH state and idle mode are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble and receives an acquisition indicator acknowledging the RACH preamble via an acquisition indicator channel (AICH) and an index to an enhanced dedicated channel (E-DCH) resource. The WTRU determines a start of an E-DCH frame. An F-DPCH timing offset is defined with respect to one of the RACH access slot and an AICH access slot carrying the acquisition indicator. A relative F-DPCH timing offset may be signaled to the WTRU and the WTRU may determine a start of an E-DCH frame based on the relative F-DPCH timing offset and timing of an AICH access slot including the acquisition indicator. The WTRU may transmit a dedicated physical control channel (DPCCH) power control preamble before starting an E-DCH transmission.

A wireless transmit/receive unit (WTRU) sending a first data signal via an enhanced dedicated channel (E-DCH) is provided. The WTRU may reconfigure physical channel parameters based on a reconfiguration message. The WTRU may subsequently send a second data signal without performing a synchronization procedure.

The application is at least directed to a core network including a non-transitory memory having instructions stored thereon for registering a network function or network function template in the core network. The network includes a processor, operably coupled to the non-transitory memory. The processor is configured to perform the instruction of determining that registration of the network function or network function template is acceptable. The processor is also configured to perform the instruction of transmitting a message including the network function or network function template to a repository in the core network. The processor is also configured to perform the instruction of verifying the network function or network function template against existing policies in the core network. The processor is also configured to perform the instruction of registering the network function or network function template in the repository after verification. The application is also directed to a core network that discovers a network function or network function template therein. The application is also directed to a core network that instantiates a network function.

A 5G Network Architecture uses virtualization and network slicing. The user equipment (UE) interacts with an underlay network that interacts with virtual network slices. The UE interacts with the underlay network (ULN) to establish a connection to a virtual network slice. Procedures are defined to assign a new slice instance to a UE (UE initiated and ULN initiated); to change a UE Profile (UE initiated and ULN Initiated); and to change a UE's assigned slice instance (ULN Initiated).

A method and apparatus for supporting machine-type communications (MTC) are disclosed. A wireless transmit/receive unit (WTRU) may configure itself to operate in a mobile-originated-only mode. The WTRU may perform no, or a subset of, radio resource control (RRC) idle and/or non-access stratum (NAS) idle/standby state procedures in the mobile-originated-only mode. For example, the WTRU may perform cell reselection but not paging monitoring in the mobile-originated-only mode. Alternatively, the WTRU may perform paging monitoring but not cell reselection and location update. The operation in the mobile-originated-only mode may be triggered explicitly or implicitly. For example, the WTRU may operate in the mobile-originated-only mode if an inactivity timer expires. The WTRU may switch the mode in accordance with a pre-configured schedule. After transition of the operation mode, the WTRU may send a message to the network indicating such mode switch.

A method and apparatus for fast control channel feedback for multiple downlink carrier operations are disclosed. A wireless transmit/receive unit (WTRU) receives signals over a plurality of downlink carriers, generates feedback for each of the plurality of downlink carriers based on the received signals, and transmits via a plurality of antennas, the feedback for at least one of the plurality of downlink carriers over a first physical channel and feedback for another of the plurality of downlink carriers over a second physical channel.

A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A WTRU includes a memory, a receive unit, a transmit unit and a control unit. The memory stores coexistence gap patterns. Each of the coexistence gap patterns defines a pattern of transmission periods and silent periods for the WTRU and corresponds to a respective duty cycle. The receive unit receives from a base station information regarding a duty cycle for a wireless cell operated by the base station. The control unit selects one of the coexistence gap patterns based on the received information regarding the duty cycle for the wireless cell and controls the transmit unit to transmit information during the transmission periods and not transmit information during the silent periods of the selected one of the plurality of coexistence gap patterns.

A synchronization procedure in a wireless network is disclosed. A network device receives, from a wireless transmit/receive unit (WTRU) in a CELL_FACH state, data via an enhanced dedicated channel (E-DCH). The WTRU may transition to a CELL_DCH state from the CELL_FACH state. The WTRU may transition to the CELL_DCH state without subsequently performing a synchronization procedure A.
