Abstract: A method for mapping downlink dedicated pilots to resource elements in an Extended Cyclic Prefix frame structure, applied in a long term evolution system, includes the following steps: the first downlink dedicated pilot of each port is mapped to the specific position of a physical resource block; other downlink dedicated pilots of the port are mapping-processed according to the time-domain interval, frequency-domain interval and a preset regulation; the time-domain interval is two or three OFDM symbols, and the frequency-domain interval is two subcarriers of the same time domain. By defining the positions of pilots in the physical resource block, downlink dedicated pilots can obtain the information of all channels when a base station uses a beamforming of more than four antennas. Making the channel information obtained by dedicated pilots contain the real channel information and the process-weight-value of a beamforming, a UE does not need to obtain the transmission-weight-value of a beamforming, thereby avoiding the feedback overhead of beamforming weight-values.

Abstract: A cell within cellular network includes user equipment (UE) that transmits data to a base station (eNB). When a UE does not have data to transmit, it may enter a low power mode (DRX) having silent intervals during which the eNB does not expect to receive a transmission from the UE and the UE is not required to monitor DL control channels from the eNB. While in DRX mode, the UE may detect an event, such as data ready for transmission or a need to request a timing adjustment (TA) update. The UE transmits a scheduling request indicator (SRI) to the eNB in response to detection of the event, wherein the SRI carries information identifying the triggering event.
