Abstract:
In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored (503) based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.
Abstract:
A method for transmitting a data frame in a wireless communication system begins by creating a time of arrival (TOA) window, including a window start (WS) and a window end (WE). The TOA of the data frame at the air interface for transmission is determined, and further action is taken depending upon when the data frame arrives relative to the TOA window. The data frame is buffered if the TOA is before the WS. The data frame is transmitted if the TOA is within the TOA window. The data frame is discarded if the TOA is after the WE.
Abstract:
A wireless transmit/receive unit (WTRU) and a Node B, respectively, perform joint randomness not shared by others (JRNSO) measurement to generate JRNSO bits based on a channel estimate between the WTRU and the Node B. The WTRU and the Node B then perform a reconciliation procedure to generate a common JRNSO bits. The Node B sends the common JRNSO bits to a serving network. The WTRU and the SN secure a session key (such as an integrity key, a cipher key and an anonymity key), using the common JRNSO bits. The JRNSO measurements are performed on an on-going basis, and the session key is updated using a new set of common JRNSO bits. The JRNSO bits may be expanded by using a pseudorandom number generator (PNG) or a windowing technique. A handover may be intentionally induced to increase the JRNSO bits generation rate.
Abstract:
A method and apparatus for efficient operation of an enhanced dedicated channel (E-DCH) are disclosed. A physical layer processing includes computation of various control parameters followed by actual processing of the data to be transmitted. In accordance with the present invention, the computation of the control parameters is performed asynchronously from the associated data operation. A medium access control (MAC) layer provides information needed for computation of the control parameters to the physical layer as early as possible, while the data is being processed in parallel. The provided data includes a hybrid automatic repeat request (H-ARQ) profile, a transport block size, power offset, or the like. By sending this data to the physical layer before MAC-e processing is complete, the latency constraint can be significantly relaxed.
Abstract:
A controlling radio network controller (C-RNC) for use in radio resource management (RRM) functions includes a radio resource management function for managing radio resources. The RRM function uses data stored in a common database, including cell data and wireless transmit/receive unit (WTRU) data. The cell data includes resource assignment information for a cell, and the WTRU data includes WTRU capability and WTRU radio link information.
