  • Publication number: 20090042568
    Abstract: A method for controlling radio communication such as mobile phone communication is provided for preventing an endless loop of a request for retransmission that is issued by a device on a reception side to a device on a transmission side. The transmission device performs processes of counting, for each RLC-PDU, the number of times when a request for retransmission is issued by the reception device (#524), and transmitting control information indicating that a process of receiving the RLC-PDU should be skipped to the reception device when the number of times of the request for retransmission of the RLC-PDU reaches a threshold value (#528).

  • Publication number: 20090041056
    Abstract: Instead of adding control information that should be passed on to two or more RLC entities or two or more PDCP entities on the counterpart side to data respectively in two or more RLC entities or two or more PDCP entities at the sending end, control information is added in MAC entity and then distributed to two or more RLC entities in MAC entity on the counterpart side.

  • Publication number: 20090042514
    Abstract: Transmission and reception of a data unit such as RLC-PDU is performed more efficiently than the conventional method when a retransmission control is performed in radio communication such as mobile phone communication. If poll information is transmitted after RLC-SDU of a logical channel #1 has already been transmitted to a mobile phone terminal, the RLC-PDU is generated by using a header including the poll information but not by using the RLC-SDU on a layer 2 and then the RLC-PDU is sent to a layer 1.

  • Publication number: 20090044068
    Abstract: A method for counting correctly substantial transmission times of a data unit such as an RLC-PDU even if the data unit is divided before being transmitted is provided. The method includes the steps of preparing a counter for the RLC-PDU (#503), making a storage portion store a pointer indicating a position of a division PDU of the RLC-PDU to be transmitted every time when the division PDU obtained by dividing the RLC-PDU is transmitted (#504), determining whether or not the transmission times should be counted along with a transmission of the division PDU to be transmitted based on the pointer of the division PDU to be transmitted and the pointer of a division PDU that was transmitted last time (#505, #506 and #507), and making the counter perform the count process when it is determined that the transmission times should be counted (#508).

  • Publication number: 20090041055
    Abstract: MAC entity produces a single PDU in such a way that two or more SDU's, which are received from RLC entity via logical channels, are integrated, and header H and MAC control information CONT are added. Transmission order information (time stamp TS) is added to the PDU. The PDU including the transmission order information is transferred to a transport channel, and then transmitted on a radio basis to an apparatus of the other party.

  • Publication number: 20080219291
    Abstract: The transmission side adds retransmission identification information to the RLC sub-PDUs obtained by dividing an RLC PDU, and transmits the RLC sub-PDU with the retransmission identification information added thereto. The reception side refers to the retransmission identification information added to the received RLC sub-PDUs, and stores only the RLC sub-PDUs having retransmission information the same as an assumed value which is preset, into a buffer, and assembles an RLC PDU using the RLC sub-PDUs having the same retransmission identification information.

  • Patent number: 7407889
    Abstract: The present invention improves a method of forming a surface unevenness using a difference in etching rates, and relaxes limitations on substrates in this method. In a method of the present invention, an uneven surface is formed by a method including applying pressure to a predetermined region in a surface of a thin film formed on a substrate, and etching a region including at least a portion of the predetermined region and at least a portion of the reminder of the surface that excludes the predetermined region. An etching rate difference within the thin film increases freedom in selecting a substrate material.

  • Publication number: 20070138130
    Abstract: The present invention provides a glass substrate having a minute texture being provided on the surface and having good acid durability with high protrusion forming efficiency. According to the present invention, unevenness is formed on the surface by pressing a predetermined area of the surface of the glass substrate containing at least one oxide selected from the group consisting of SiO2, B2O3, P2O5, GeO2, As2O5, ZrO2, TiO2, SnO2, A2O3, MgO, and BeO and having a composition wherein the content of this at least one oxide is above 90 mol %, and subsequently by etching an area including this predetermined area. In the composition of this glass substrate, the ratio of oxides of network formers or intermediates is high, so that the glass substrate becomes easy to be compressed. This enables to obtain high protrusion forming efficiency even when selective leaching of a component easily leached into etchant is not employed, thereby satisfying acid durability as well.

  • Patent number: 7041896
    Abstract: The invention provides a housing for an electronic apparatus whose components can be worked through a reduced number of steps without deteriorating the shielding performance against electromagnetic waves. The housing for an electronic apparatus includes a plurality of metal plates including a first metal plate and a second metal plate and each having a coated face coated over an overall area thereof and a non-coated face. The metal plates are assembled to form the housing such that the coated faces thereof are exposed as outer faces to the outside of the housing. The first metal plate is bent back at a portion thereof such that the non-coated face thereof is exposed to the outside to form a contact portion on a side edge of the first metal plate. The first metal plate is coupled to the second metal plate with the non-coated face of the contact portion thereof held in contact with the non-coated face of the second metal plate to establish electric connection between the first and second metal plates.
