  • Publication number: 20120147453
    Abstract: By forming a corresponding colored layer under the pixel electrode having a predetermined pattern of the electronic paper display substrate, the pattern displayed in the region where the pixel electrode and the colored layer is disposed has the color of the colored layer when displaying. Compared with the transparency color, the color of the colored layer can make the contrast of the pixel region to the non-pixel region high and display colorful pattern.

  • Publication number: 20120069778
    Abstract: The present invention provides a method, device and system for backhaul link communication in a TDD system. Wherein, the method includes: a base station allocating an uplink subframe for uplink transmitting of the backhaul link and a downlink subframe for downlink transmitting of the backhaul link, and notifying subframe allocating information to a relay node; and the base station communicating with the relay node by the uplink subframe and the to downlink subframe of the backhaul link. The solution allocates the uplink subframe and the downlink subframe of the backhaul link according to certain rules, performs related HARQ operation based on the allocated uplink subframe and downlink subframe, and ensures the availability and reliability of backhaul link communication.

  • Publication number: 20120044852
    Abstract: The present invention discloses a resource scheduling method and system, a BS and a RN, which include that: the BS allocates an uplink subframe for performing uplink transmission of a backhaul link and a downlink subframe for performing downlink transmission of the backhaul link, and informs the RN of the allocation information of the uplink subframe and the downlink subframe of the backhaul link, or the BS only informs the RN of the allocation information of the uplink subframe or the downlink subframe of the backhaul link; the RN may determine, according to the received allocation information and a predefined timing relationship, an uplink subframe and a downlink subframe of the backhaul link of which the BS does not inform. By the solution of the present invention, an MBSFN subframe can be indicated to the RN, and uplink transmission conflict can be avoided.

  • Patent number: 8072932
    Abstract: A method for physical layer random access in wideband TDD mobile communication system is disclosed, and the method comprises: receiving the system broadcast message of the cell, obtaining the configuration information of the frequency band in frequency domain in the UpPTS time slot of the cell; and the terminal sends random access sequences to the BS in the UpPTS time slot according to the configuration information of the frequency band in the UpPTS time slot. The configuration information of the frequency band in frequency domain in the UpPTS time slot comprises the information about the frequency band number that the total bandwidth used is divided in the UpPTS time slot, the information about the bandwidth size of each frequency band, and the information about the position of the frequency point.

  • Publication number: 20110044181
    Abstract: The present invention discloses a method for processing uplink signal. In this method, when a random access channel of a cell where a user equipment (UE) locates is within an uplink pilot timeslot, the UE determining whether there is a conflict between the random access channel and time-frequency position of an uplink channel quality sounding pilot of the UE; and if there is a conflict, the uplink channel quality sounding pilot will not be transmitted by the UE within the uplink pilot timeslot. The present invention also discloses a system and apparatus for processing uplink signal. By applying the method, system and apparatus of the present invention, the interference to detection performance of the random access channel caused by the uplink channel quality sounding pilot will be avoided, thereby increasing the detection performance of the random access channel.

  • Publication number: 20100265910
    Abstract: Embodiments of the present invention provide a method, system and apparatus for assigning pilot resources. By assigning all or part of time and frequency resources of at least one configured SC-FDMA symbol in an UpPTS to an uplink SRS symbol and sending an assigning result to a mobile terminal, time and frequency resources in the UpPTS can be assigned to the uplink SRS symbol, so that after receiving the assigning result, the mobile terminal can send the uplink SRS symbol by using the time and frequency resources assigned to the uplink SRS symbol according to the assigning result.
