Abstract: A method for configuring an interworking wireless local area network (I-WLAN) user equipment (UE) to access a third generation partnership project (3GPP) system begins by initiating a connection from a UE to the 3GPP system, the initiating step including indicating the UE's interworking protocol capabilities. Authentication and authorization of the UE connection by the WLAN to the 3GPP system is requested, including indicating the UE's interworking protocol capabilities. The 3GPP system determines whether to accept the UE's request, including examining the UE's interworking protocol capabilities. An interworking protocol is instantiated at the UE, whereby the UE is configured to interwork with the 3GPP system.

The pedal clasping portion has the form of a deep channel firmly affixed to the elongate body portion of the device and may have a cutout in one of the flanges through which the pedal arm passes.
Abstract: The present digital camera system includes interchangeable lens barrels, and a digital camera having a first camera body to which the interchangeable lens barrel can be attached or another digital camera having a second camera body. The first camera body contains a first image pickup element having a reference pixel pitch and a first optical LPF (low pass filter). The second camera body contains a second image pickup element having a pixel pitch different from the reference pixel pitch, a second optical LPF and a compensating optical element. The compensating optical element is a glass plate having no double refraction characteristic for compensating an amount of the change in optical path length due to the decrease in thickness of the second optical LPF with respect to the first optical LPF. The present digital camera system allows the replacement of an interchangeable lens without generating various kinds of aberration among camera bodies having different pixel pitches.

Abstract: A method and system wherein handover information is broadcast in a wireless local area network. Handover information is broadcast in a beacon frame thereby allowing WTRUs operating in a wireless area network to handover to available alternative systems as desired. WTRUs may read the beacon frame and obtain appropriate information for handing over to alternative systems having coverage areas that overlap that of the wireless local area network. The alternative systems may be any type of wireless system and the wireless local area network may be any type of wireless area network.
Abstract: The invention relates to a method of testing a compound for biological activity, which method comprises providing cells expressing one of the CD94/NKG2 family of receptors, contacting the cells with recombinant HLA-E under binding conditions in the presence of the test compound, and determining whether the presence of the compound affects the binding of HLA-E to the cells. The HLA-E property of binding to CD94/NKG2 receptors on NK cells and a subset of CD8+ T cells is useful for targeting CD94/NKG2+ cells for a variety of purposes such as identification, isolation, killing or inactivation.

The valve mechanism (90) comprises a disc (10) with an axle (15), a rotatable annular cover piece (20) and an annular turning piece (40). A spring (30) is disposed between the cover piece (20) and the turning piece (40).
Abstract: A system and method to optimize the number of uplink and downlink slots, given the maximum number of crossed slots between any two cells is disclosed. The present invention effectively assigns a direction (i.e. uplink or downlink) to every slot in every cell of the system, taking into account the trade-off between: a) avoiding base-to-base or mobile-to-mobile interference; and b) matching the slot assignment of every cell as closely as possible to the local traffic conditions. The present invention assigns users to slots according to their transmission power requirements in order to allow conflicting slot-to-cell assignments between two cells in the same geographic region.
Abstract: A porting layer takes software developed using a single threaded modeling tool to a multiple threaded environment. The single threaded modeling tool is used to model the software. The porting layer ports in variables into a multiple threaded operating environment by reference and not as variables so that each thread can access variables by reference.
Abstract: A method and system for determining thresholds for evaluating inter-system handovers in a wireless communication system includes determining a quality level of a first digital duplexing type, determining a quality level of a second digital duplexing type, and comparing the quality levels to determine whether to handover from the first digital duplexing type to the second duplexing type.
Abstract: A method and apparatus for supporting Adaptive Modulation and Coding (AM&C) and Hybrid Automatic Repeat Request (H-ARQ) functions in a cellular system including at least one wireless transmit/receive unit (WTRU) and a Node B. A signal is received at the WTRU indicating a need for AM&C and H-ARQ control signaling. An AM&C and H-ARQ control signaling transport channel (TrCH) is dynamically allocated by informing a transport format selection process of the need for AM&C and H-ARQ control signaling. The transport format is selected for required transmission time intervals (TTIs) which assign transport format combinations (TFCs) to establish the AM&C and H-ARQ control signaling transport channel.
Abstract: A wireless communication method and apparatus for scheduling data having different priorities for a plurality of wireless transmit/receive units (WTRUs), (i.e., users) is disclosed. The normalized average active throughput for each of the WTRUs is computed. Then, the normalized channel quality for each of the WTRUs is computed based on a reported channel quality indicator (CQI) and the respective normalized average active throughput. A sequence of WTRUs is arranged in an order of decreasing normalized channel quality for each data priority. As much of the data as possible is scheduled for the WTRUs in the order of decreasing normalized channel quality of WTRUs. The scheduling is performed until there are no more physical resources available. Several of the WTRUs can be scheduled in the same transmission timing interval (TTI) if there are enough physical resources.
Abstract: A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL. The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

Abstract: A method and apparatus for scheduling transmissions via an enhanced dedicated channel (E-DCH) are disclosed. A scheduled power is calculated for scheduled data flows. A remaining transmit power is calculated for the E-DCH transmission. A rate request message is generated, wherein the scheduled power, remaining transmit power and rate request message are used to select transport format combinations (TFCs) and multiplex data scheduled for the E-DCH transmission. The remaining transmit power is calculated by subtracting from a maximum allowed power the power of a dedicated physical data channel (DPDCH), a dedicated physical control channel (DPCCH), a high speed dedicated physical control channel (HS-DPCCH), an enhanced uplink dedicated physical control channel (E-DPCCH) and a power margin.

Abstract: A method of data estimation for a Time Division Duplex (TDD) Code Division Multiple Access (CDMA) system or any other system using an extended algorithm (EA) in preference to a truncated algorithm (TA). The EA avoids implementation errors by choice of proper extended matrices, and accepts the use of one piece of hardware. The EA also obviates loss of multiple signals in the tail part of each data field, and avoids errors due to transformation of a Toeplitz matrix to a circulant matrix.
Abstract: A wireless communication system having a Node B and a plurality of wireless transmit/receive units (WTRUs), includes a contention-based uplink (UL) channel and at least one downlink (DL) physical channel. The UL channel supports UL transmissions from the WTRUs to the Node B. The UL channel is randomly accessed by a WTRU when the WTRU is ready to transmit data. The DL physical channel supports DL transmissions from the Node B to the WTRUs. The DL transmissions include an acquisition indicator and information regarding said acquisition indicator. The acquisition indicator confirms whether the data transmitted over said UL channel was successfully received by the Node B.
