20120188897 | Terminal Access Method, System and Associated Devices - A terminal access method is disclosed. The method includes the following steps: the terminal receives an auxiliary synchronization signal sent by a base station on a transmission resource which is chosen from an uplink and used for transmitting downlink data; the terminal calculates transmission power according to the auxiliary synchronization signal; and the terminal sends a Random Access Channel (RACH) access preamble code to the base station according to the transmission power and performs a RACH access process. In this technical solution, the auxiliary synchronization signal is transmitted in a special sub-frame selected from the uplink, which makes it possible for the terminal to obtain the channel quality information of the uplink by receiving the auxiliary synchronization signal during a cell synchronization stage, and determine the transmission power according to the channel quality information of the uplink before the RACH process occurs, thereby reducing the step of adjusting the transmission power and shortening the time of the random access of the channel. A terminal access system and associated devices are also provided. | 07-26-2012 |
20130021964 | METHOD, SYSTEM AND DEVICE FOR WIRELESS COMMUNICATION - A method, system and device for wireless communication are provided by the present invention. The method includes that: from the ending of the Transmit-Receive Guard interval (TRG) to the beginning of the Receive-Transmit Guard interval (RTG), an evolved Node B (eNB) carries Common Reference Signals (CRSs) or Demodulated Reference Signals (DMRSs) on the carriers are used for transmitting data signals and/or control signals to a Relay Node (RN); the RN demodulates, according to the CRSs or the DMRSs, the signals transmitted by the eNB; the TRG is the guard interval of the transition, for the RN, from transmitting signals to receiving signals over the backhaul link, and the RTG is the guard interval of the transition, for the RN, from receiving signals to transmitting signals over the backhaul link. The application of the present invention enables the RN to receive the data signals and/or control signals transmitted by the eNB correctly. | 01-24-2013 |
