  • Publication number: 20140024369
    Abstract: The present invention discloses a method and a device for discovering a UE, a first UE and a base station. The method for discovering a UE comprises the steps of: monitoring, by a first UE, an uplink signal in a mobile communication system; extracting, by the first UE, first information for identifying a UE that is to be discovered and that transmits the uplink signal from the monitored uplink signal; transmitting, by the first UE, a monitoring report message carrying the first information to a base station, acquiring, by the first UE, the device ID of the UE to be discovered in accordance with the monitoring report response message and completing the discovery process of the UE. According to the present invention, it is able to discover the UE without changing a channel system of an existing system and occupying time-frequency resources of the system.

  • Patent number: 8548476
    Abstract: Disclosed is a method of managing an X2 interface, a handover method, an interference coordination method and an apparatus for LTE and LTE-Advanced system. X2 interface management includes: finding by a first eNB, a new neighboring cell, i.e., a second cell corresponding to a second HeNB; determining by the first eNB, an access mode of the second cell; and establishing a first X2 interface between the first eNB and the second HeNB when the access mode of the second cell is an open mode or a hybrid mode. The X2 interface may be managed dynamically and the mode for establishing the X2 interface, such as direct X2 interface or gateway-proxied X2interface, may be selected. The expansible problem and system overhead due to the X2interface in the LTE and LTE-Advanced system may be reduced effectively to better support handover and interference coordination.

  • Publication number: 20070262891
    Abstract: A PCI Express device is provided. The PCI Express device includes a symbol lock module that includes a state machine for detecting a special character in a serial bit stream received from a serial/de-serializer, wherein the state machine receives a first special character and verifies alignment of the special character by comparing with a previously stored alignment value and the state machine declares a symbol lock if at least more than one special character alignment matches with a same stored alignment value. The special character is a comma sequence. After a symbol lock is declared, the state machine continues to monitor incoming bit stream data and compares each new special character alignment with the previously stored alignment value. During the monitoring if a misaligned special character is detected, then the state machine waits to receive another special character before declaring a loss of synchronization.

  • Publication number: 20030087603
    Abstract: A framing method and the synchronous wireless system therewith, wherein the method includes the steps of: partitioning the data stream into frames according to the frame length, in which the number of sub-frame in each frame can be determined by the periodicity of selected LA codes; forming each sub-frame by a plurality of time slots, in which the number of the said time slots can be determined by the number of pulses of the said LA codes, and the said time slot length varies with the variation of the pulse interval of the said LA codes; and filling in each time slot by modulation with the selected orthogonal spread spectrum codes. Different base stations from different, nearby cells shall be assigned different LA-CDMA codes so that adjacent cell interference can be reduced. While in nearby cells, the same spreading code can be assigned, therefore greatly reducing requirement for the number of spreading codes, as well as the requirement for the lengths of the spreading codes.

  • Publication number: 20030083014
    Abstract: In accordance with the present invention, a method is provided for a mobile station to select one cell site in a plurality of cell sites in cellular systems with an Interference Free Window. This method is based on measurement of the signal on the downlink. In preferred embodiments, a mobile station receives the downlink spread spectrum signals from a plurality of neighboring cells. By using a RAKE type correlator or matched filter, the signal energy and the multipath delay spread profile can be estimated at the mobile station. A new function is defined as the ratio of the multipath delay spread to the energy of the received signal. Minimizing the said function will result in a cell site that provides the best quality of service in a multipath propagation environment.

  • Publication number: 20030076874
    Abstract: A reverse synchronization method, which is used in a wireless system utilizing orthogonal spreading codes with Interference Free Window characteristic, wherein the transmission time of the signal from a remote unit is adjusted with respect to a predetermined Interference Free Window [−n, +n], such that the arrival time in a base station of the signal from the said remote unit falls within the said predetermined Interference Free Window. This eliminates inter-symbol interferences and multiple access interferences when multipath signals from a same remote unit and signals from different remote units arrive within an Interference Free Window.
