| 20080274738 | Method For Communication Between A Wlan Radio Station And A Base Station Of A Cellular Radio Communications System, And Corresponding Radio Station And Base Station - A radio facility receives a request, which is made by a first radio station and which is routed by a second radio station to the radio facility, regarding a future sending of a message from the first radio station to a third radio station. In addition, the radio facility sends, to at least one or to each radio station of a path, which extends over one or more radio stations and via which the message can be transmitted from the first radio station to the third radio station by routing it through radio stations of the path, information concerning the radio station adjacent to the respective radio station of the path along said path in the direction of the third radio station and, optionally, also information concerning radio resources to be used in the event of a routing of the message through the respective radio station of the path. A radio facility and a radio station carry out said method. | 11-06-2008 |
| 20090303925 | Method and Node for Providing a Quality of Service Support in Multihop Communication Systems - A method and apparatus according to the technique wherein support of a quality of service is provided for transmissions between at least one node (N) and at least one mobile station (MS | 12-10-2009 |
| 20100130193 | METHOD AND APPARATUS OF USING A RELAY STATION TO ASSIST PROCESSING OF REQUESTS FROM USER ENDS - A method of uses a relay station to assist processing of requests from user ends. The relay station acquires and monitors channel resource information received from a base station. Upon receiving a request from the UEs via the channel resource, the relay station sends the request received to the base station if it detects no response from the base station to the request. An apparatus uses a relay station to assist processing of requests from UEs. A channel resource acquisition unit acquires channel resource information from the base station. A user monitoring unit monitors the channel resource acquired by the channel resource acquisition unit and for receiving requests sent from the UEs. A base station monitoring unit monitors response from the base station to the requests upon receiving the requests sent from the UEs. A transmitting unit sends the request to the base station when no response from the base station to the request is detected. | 05-27-2010 |
| 20100207731 | Method and Reader to Conduct a Label Query in a Radio Frequency Identification System - A method for conducting a passive label query in a radio frequency identification system, wherein a query process conducted by a reader for a group of passive labels comprises a first query and a subsequent query. The link frequency used by a reverse link from the passive label to the reader in the subsequent query is smaller than that the link frequency used by the reverse link in the first query. The method improves the reverse link performance of a passive label radio frequency identification system, and increased the reading success rate of the passive label. A reader is also provided to implement the method. | 08-19-2010 |
| 20100285743 | METHOD, SYSTEM, RELAY STATION AND BASE STATION FOR TRANSMITTING DATA MOBILE COMMUNICATION - A mobile communication data transmission method for a cell having one base station and more than one relay station involves switching the relay stations between at least two operating modes of signaling transmission under the control of the base station. A system transmits mobile communication data in a cell having one base station and more than one relay station. When transmitting an uplink signaling or a downlink signaling, the relay stations switch between at least two operating modes under the control of the base station. By using the method, network, relay station, and base station, data transmission in multiple modes can be achieved, so as to achieve a flexible relay scheme. | 11-11-2010 |
| 20100321166 | Radio Frequency Identification Reader/Writer and a Method for Implementing Antenna Switching - An RFID reader/writer including a reader/writer body, antennas and an antenna switching unit is provided. The reader/writer body distributes to each of its own ports a length of sustained time for transmitting a signal. One end of the antenna switching unit is connected to one port of the reader/writer body, while the other end is connected to two antennas. The antenna switching unit acquires a length of sustained time for the signal transmission distributed to the port by the reader/writer body, configures the time-length for the signal transmission and the sequence thereof of the two antennas according to the length of sustained time for the signal transmission, obtains a configuration result for signal transmission, and performs a switching control on the signal transmission of the two antennas according to the signal transmission configuration result. Further, an implementation method for the antenna switching of the RFID reader/writer is described. | 12-23-2010 |
| 20110037570 | Communication Method for a Radio System and Apparatus and System for Implementing the Method - An apparatus, system and communication method, which is particularly suited for a radio frequency identification system (RFID), wherein a reflection-transmission apparatus is disposed in a radio system and, during a communication process, the reflection and transmission features of reflection-transmission apparatus presented at the radio frequency are changed to introduce a multi-path signal component which changes with time. Consequently, during the communication process, a receiving apparatus receives and combines the multi-path signal component of communication signals and the radio system performs communication by utilizing time diversity effects. The apparatus, system and method provide effective and continued reduction of communication blind spots in the RFID system, thereby improving the overall success rate for the RFID system to read tags and accomplishing a better balance with the overall reading time. | 02-17-2011 |
| 20110037575 | Method and Apparatus for Providing Energy to Passive Tags in a Radio-frequency Identification System - A method and an apparatus for providing energy to passive tags in a radio-frequency identification system in which a radio-frequency identification system uses the passive tags, a reader/writer sends commands and continuous waves alternately during a communication process, and the tags can obtain energy from these signals sent by the reader/writer, wherein at least one period is selected from those periods for transmitting the continuous waves, and for the continuous wave transmitting signals during this period, an enhanced transmitting power is used, or a extended transmitting time is used, or during this period continuous waves are sent additionally to the passive tags by an independent energy supplying apparatus provided separately, so that the passive tags can obtain from the continuous waves during the selected period more energy for reading and/or writing, thereby improving the reliability of the reading and/or writing operations, and increasing the rewritable range of the radio-frequency identification system. | 02-17-2011 |
