Abstract: A method and apparatus for selecting a TFC in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU estimates a transmit power for each of a plurality of available transport format combinations (TFCs). A TFC is selected for an uplink dedicated channel and a TFC is selected for an enhanced uplink (EU) channel. The TFC for the dedicated channel is selected first and independently of the TFC selection of the EU channel. The TFC for the EU channel is selected within a remaining WTRU transmit power after the TFC selection for the dedicated channel.

Abstract: The present invention discloses a method and system for enabling efficient reduction of TFCs in the TFCS to achieve desired transmission, while remaining within desired power and data requirements. Upon the UE transmission power requirement exceeding the maximum or allowable transmission power the MAC shall be informed for subsequent TFC selection of all TFCs that currently exceed this limit. The UE will then chose the TFC with the next lower transmission power requirement and the sequence will continue until an acceptable TFC is determined. The present invention also enables the replacement of the TFCs in the TFCS and advanced determination of non-supported TFCS. The TFCs that require transmission power greater then the maximum or allowed UE transmission power shall be determined continuously in every TTI, not just in TTIs where the maximum power has been exceeded.

Abstract: A radio access network comprises a serving radio network controller (S-RNC). The S-RNC receives successfully received medium access control (MAC) packet data units (PDUs), discards duplicates of MAC PDUs, reorders the non-discarded MAC PDUs based on serial numbers of the MAC PDUs and delivers the MAC PDUs to a radio link control protocol layer. A controlling radio network controller (C-RNC) provides information to Node-Bs under its control for use in scheduling uplink transmissions. A plurality of Node-Bs schedule uplink transmissions in response to the information provided by its C-RNC, transmit scheduling information to user equipments of its cells, receive MAC PDUs from user equipments of its cells using hybrid automatic repeat request and forward the successfully received MAC PDUs to an associated S-RNC.

Abstract: A method and wireless communication system for providing channel assignment information used to support an uplink (UL) channel and a downlink (DL) channel. The system includes at least one Node-B and at least one wireless transmit/receive unit (WTRU). The WTRU communicates with the Node-B via a common control channel, the UL channel and the DL channel. The WTRU receives a message from the Node-B via the common control channel. The message includes an indication of whether the message is intended for assigning radio resources to the UL channel or the DL channel. The WTRU determines whether the message is intended for the WTRU and, if so, the WTRU determines whether the message is for assigning radio resources to the UL channel or the DL channel. The WTRU takes an appropriate action based on whether the message is for assigning radio resources to the UL channel or the DL channel.

Abstract: A user equipment determines transport format combinations (TFCs) that are available for at a dedicated channel (DCH) based on at least a maximum transmit power for the user equipment. A TFC is selected from the available TFCs for the DCH. Based on a remaining power after the TFC selecting, enhanced uplink TFCs (E-TFCs) are selected that are available for an enhanced dedicated channel (E-DCH). An E-TFC is selected for the E-DCH from the available E-TFCs.

Abstract: A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

Abstract: A user equipment (UE) for controlling transmission power levels in a system employing a spread spectrum time division duplex (TDD) technique having frames with timeslots for communication comprises a measuring device configured to receive, during a first time slot, a communication including a power level and measure the power level of the received communication and an interference power level. A pathloss estimation device determines a pathloss estimate and a long term pathloss estimate, based in part on the measured power level and the received power level. A quality measurement device determines a first quality factor, ?, and a second quality factor, 1??, of the pathloss estimate based in part on a number of timeslots, D, between the first and a second timeslot. A transmit power calculation device sets a transmission power level for transmission during the second timeslot.

Abstract: In a radio network controller (RNC), a covariant matrix and a database are updated. The RNC then detects that a first base station's time-error-variance exceeds a predetermined threshold. In response, the RNC signals to a user-equipment (UE) to measure a time difference of arrival (TDOA) between signals transmitted from the first base station and a reference base station. The UE measures the requested TDOA between the designated base stations and reports the measurement results back to the RNC. The RNC then compares the measured TDOA with a TDOA value stored in the database. Based on the comparison, the RNC signals to the first base station to adjust its time base.
