Abstract: Disclosed is a method and apparatus for transmitting/receiving a packet in a mobile communication system. When upper layer packets are multiplexed into a packet whose overall size is informed via a separate path, the size of the upper layer packet is not signaled if it can be calculated from the overall size of the packet, so that the size a packet transmitted/received over a radio channel can be reduced.

Abstract: In a closed-loop wireless communication system, a codebook-based precoding feedback compression mechanism is provided to remove redundancy from the precoding feedback that is caused by channel correlation in time and frequency. Redundancy due to temporal correlation of the transmission channel is removed by sending precoding feedback only if there is a change in the precoder state for the channel to the receiver. Redundancy due to frequency correlation is removed by run length encoding the precoding feedback, thereby compressing the precoding feedback prior in the frequency domain. By compressing the precoding feedback, the average rate of precoder feedback is reduced.

A cam mechanism (support mechanism) supports the liquid crystal display part switchably between a vertical position and a horizontal position and to allow the liquid crystal display part to turn both clockwise and counterclockwise as viewed from the front.

Abstract: The guard band between two carriers of the same or different operators is reduced or dynamically adjusted by initiating a dynamic change request of the guard band between the two carriers to allow for flexible spectrum use by adjusting the tolerable guard band overlap. The data is distributed or positioned in the carrier spectrum band as a function of the Quality of Service so that the lowest Quality of Service constrained data are positioned at the edges of the carrier spectrum band and the highest Quality of Service constrained data are positioned in the middle of the carrier spectrum band to minimize any impact from the increased adjacent channel interference due to the guard band overlap and narrower guard band.

Abstract: A terminal and method and system for processing SUPL are discussed. According to one embodiment, the invention provides a method of processing a SUPL request for a terminal that has performed roaming, the method comprising: receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; checking the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode; and selectively performing authentication with the home SLP entity based on the checking result indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode.

Abstract: A method an apparatus for selecting a forward link and return link data rate for a constant power, variable data rate two-way, mobile satellite communications link. The forward link and return link signal strength (in the form of carrier power to noise power spectral density ratio) is measured, cataloged, and the values are used for the data rate selection. In addition, a ping can be sent by the network operation center to the mobile unit and the response to the ping is used for updating the information of both forward link and return link signal strength, so the chance of wrong data rate selection can be reduced. Multiple re-transmission attempts combined with gradually increased re-transmission margin ensures the proper data rate decision can be eventually achieved even with occasionally inaccurate signal strength information.

Abstract: A method of locating and tracking a cellular terminal (1) is described. The method comprises the detection of one or more handover events that take place when the cellular terminal (1) moves between transmission regions (3) of a cellular terminal network provider. Information regarding the handover events is recorded within a database (4) so that the location of the cellular terminal (1) can be calculated. The calculation of the location of the cellular terminal (1) is achieved by either comparing the information with previously stored data or by extracting information regarding the location and geometry of the individual transmissions regions (3) such that a handover region (9) can be calculated. The precise location and area of the handover regions (9) takes account of various factors including power, time of flight of the transmitted signals and timing synchronization within transmission regions (3) and the effects of shadowing of the transmitted signals.
