A configuration method for a sounding reference signal in a Long Term Evolution Advanced (LTE-A) system is disclosed in the present invention. The method includes: an eNB triggering one or multiple User Equipment (UE) to transmit an aperiodic Sounding Reference Signal (SRS) on one or multiple uplink subframes through a downlink control signaling. An eNB in an LTE-A system is also disclosed in the present invention. The eNB includes: a transmission module, configured to: trigger one or multiple UE to transmit an aperiodic SRS on one or multiple uplink subframes through a downlink control signaling, so as to make the UE use non-periodic SRS resources to transmit the non-periodic SRS on the uplink subframes according to the triggering of the eNB after receiving the downlink control signaling sent by the eNB. User equipment in an LTE-A system is also disclosed. With the present invention, the resources used by the non-periodic SRS can be determined, channel measurement frequency of the UE can be enhanced, and channel measurement requirement of the LTE-A system can be better satisfied.

The present invention provides a device and a method for dynamically configuring Discontinuous Reception parameters, and the method includes: when DRX parameters of a terminal need to be adjusted, the DRX parameters are adjusted until the terminal satisfies the requirement of the Guaranteed Bit Rate after the adjustment of DRX, and then the DRX parameters are no longer adjusted. Adopting the technical scheme of the present invention can make a base station adapt to the power-saving and performance requirement of the terminal in real time by a dynamic estimation of the DRX adjusted parameters of the terminal, in addition, it can also satisfy the requirement for the signaling load in different circumstances by configuring an adjusted cycle.

The present invention discloses a method, device and system for configuring codebooks. The method comprises a transmitting end selecting a code word restricted sub-set and informing a receiving end of the code word restricted sub-set, the code word restricted sub-set containing part or all of code words in a first codebook and/or a second codebook; and the receiving end selecting an optimal pre-coded code word from the code word restricted sub-set and informing the transmitting end of an index of the optimal pre-coded code word. By the present invention, code word restriction is implemented in the case of dual codebooks in the LTE-A system such that the calculation complexity is reduced when the receiving end selects the code word, occurrences of the case where the receiving end selects the code word wrongly are decreased, and the signaling structure in the LTE system can be inherited very well.

Techniques are provided to determine an initial quaternion transform that is used to transform measurements received from accelerometer, rate sensor and inertial reference subsystems from a vehicle coordinate frame to an inertial navigation frame. Methods disclosed determine corrective angular rates to use as a feedback signal to rotate the quaternion transform to counter errors that result when transforming a gravity vector and an inertial reference vector (e.g., a magnetic North reference vector) that are being measured by the accelerometer and an inertial reference subsystems, respectively. The initial quaternion determination is performed during a time period when the only substantial acceleration on the vehicle is due to gravity. The initial quaternion can be used for processing various guidance, navigation and control functions.

The present invention provides a method and system for reporting neighbor cell information. The method includes: a network side sending a measurement configuration and reporting information of a drive test to user equipment; the user equipment performing the drive test, and reporting drive test results containing information of neighbor cells around the user equipment to the network side when a reporting triggering condition is satisfied (201). In the present invention, by using a Minimize drive test (MDT) measurement event in the drive test, the information of neighbor cells around the user equipment is discovered and reported to the network side for maintenance, and since the network side obtains the information of neighbor cells around the user equipment in time, the effectiveness of the user equipment performing the cell handover is guaranteed, thereby enhancing a network performance of a communication system.
