    Abstract: Embodiments of the present invention provide methods for transmitting and receiving a control channel, a base station, and a user equipment, which relate to the communication field, and can solve a transmission problem of available changing transmission resources caused by introduction of an E-PDCCH. A method includes determining, by a terminal device, a resource set and resource elements (REs) of predetermined overheads in the resource set. The REs of the predetermined overheads include an RE of at least one of a paging channel and a synchronization channel, with at least one of following REs: an RE of a channel state information-reference signal (CSI-RS), an RE of a cell-specific reference signal (CRS), an RE of a demodulation reference signal (DMRS), or a muted RE. The terminal device receives from a base station, a control channel on an RE subset comprised in the resource set, wherein the RE subset comprises a part of the REs in the resource set and do not contain the REs of the predetermined overheads.

    Abstract: Embodiments of the present invention disclose a precoding information collection method and a transmission device and relate to the communications field. A specific solution is: precoding, by a transmit side, a first pilot signal according to a first precoding matrix, and sending a precoded first pilot signal to a receive side, where the first precoding matrix is the same as a precoding matrix used for current data transmission; precoding, by the transmit side, N second pilot signals according to N second precoding matrices, and sending N precoded second pilot signals to the receive side, where N is an integer greater than or equal to 1, the second precoding matrices used for precoding the second pilot signals are different from each other, and the N second precoding matrices are different from the first precoding matrix; and receiving, by the transmit side, precoding feedback information sent by the receive side.

    Abstract: A method for updating a data table in a KeyValue database is provided. Raw data is received and formatted into a data updating file. An update timestamp is set for each column qualifier in each row of the data updating file. A data deleting file is generated. A delete timestamp is set for each row of the data deleting file. Each row of the data deleting file corresponds to one row of old data in the data table. Each row of the data deleting file includes a row key that is the same as the row key of the corresponding row of old data in the data table. The data updating file and the data deleting file are both imported into the data table. Consequently, timestamp is used to indicate the valid data in the data table. An apparatus configured to perform the method is also provided.

    Abstract: A security capability negotiation method is applicable to perform security capability negotiation during a mobile network handover. Moreover, a security capability negotiation system is also provided. Consistent with the provided system and method, it may be unnecessary for the MME to know the security capability of the corresponding eNB in a certain manner during a handover from a 2G/3G network to an LTE network. Meanwhile, during the handover from the LTE network to the 3G network, the SGSN does not need to introduce new requirements.
