| 20130058362 | Receiving Apparatus and Method for Multi-Frame Synchronization - The present invention discloses a multi-frame synchronization method, the method comprises: for each received sub-frame, a receiver determining a probability that the received sub-frame is each of sub-frames in a multi-frame, a sub-frame with maximum probability being a state of the currently received sub-frame after N sub-frames are received. The present invention further discloses a receiving apparatus for multi-frame synchronization comprising a calculation module; wherein the calculation module is configured to calculate a probability that a received sub-frame is each of sub-frames in a multi-frame, and determine a state of the currently received sub-frame based on a sub-frame with maximum probability after N sub-frames are received. The present invention effectively achieves a position for multi-frame synchronization and low calculation complexity. | 03-07-2013 |

| 20120289268 | METHOD AND DEVICE FOR ACQUIRING A PATH LOSS - Embodiments of the present invention disclose a method and a device for acquiring a path loss. The method includes: determining a current location of a terminal according to traffic channel signal strength of a current cell accessed by the terminal and broadcast control channel signal strength of at least one neighboring cell actually received by the terminal; or, determining the current location of the terminal according to broadcast control channel signal strength of at least two neighboring cells of the current cell accessed by the terminal; and acquiring a path loss of a corresponding designated neighboring cell from a correspondence according to the determined current location of the terminal. According to the embodiments of the present invention, as long as the network-side device can determine the current location of the terminal, the network-side device is capable of acquiring the path loss from the current location to any designated neighboring cell. | 11-15-2012 |
