The present invention relates to a method for defining, in a TDD wireless communication system in which broadband is configured by means of carrier aggregation, transceiving timing for a data channel and a control channel when cross-carrier scheduling is implemented.

The invention provides a beam processing method, a base station and a terminal. The beam processing method comprise the steps of receiving a first beam report reported by the terminal, wherein the first beam report includes the identification of a first preset number of transmitting beams; selecting a second preset number of transmitting beams from the first preset number of transmitting beams according to terminal capacity information or identification of a receiving beam group which is included in the first beam report and corresponds to each of the transmitting beams, wherein both the firstpreset number and the second preset number are greater than or equal to 2; and transmitting information of the second preset number of transmitting beams to the terminal, and transmitting a control channel and a data channel through the second preset number of transmitting beams, thereby being capable of improving the link recovery speed, reducing the time delay caused by the link recovery, and improving the user experience.

In a base station (100), when the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are the same, a transmission controller (102) sets a first data resource region inside a first resource region, in a resource block group (RBG), that can be used for the control channel or the data channel. When the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are different, a transmission controller (102) sets a second data resource region inside the first resource region in the RBG. The second data resource region is larger than the first data resource region.

The invention provides a multimedia service exception protection method and device. The method is applied to a multimedia network, the multimedia network at least comprises a server and a terminal incommunication connection with the server, and the server comprises a media layer. The method comprises the steps that the media layer obtains the channel state of a data channel between the terminal and the media layer, and the channel state at least comprises a normal state and a fault state. When the channel state is a fault state, the media layer counts the duration of the fault state and judges whether the duration is greater than preset time or not; and if the judgment result is yes, the media layer acquires position information of the failed data channel, and deletes the data channel according to the position information. According to the protection method provided by the invention, even if the multimedia network fails and cannot send the instruction of deleting the data channel, thedata channel can still be deleted by acquiring the position information of the failed data channel, the data channel is released in time, and the resource utilization rate of the data channel is improved.

A base station device comprises a means for preparing PHICHs, a means for mapping, according to a predetermined mapping table, each of the PHICHs of the number of user multiplexes to an I-channel or a Q-channel, and a means for notifying each of the users of a PHICH. A user device comprises a means for demodulating a downlink control signal including the allocation information of uplink radio resources, a means for transmitting, according to the allocation information, a shared data channel by using an uplink, and a means for retrieving a PHICH indicating necessity or unnecessity of retransmission of the shared data channel from the downlink control signal according to the predetermined mapping table. The mapping table indicates that when the number of user multiplexes is a predetermined number or less, a PHICH is made to be corresponding to only the I-channel or the Q-channel and when the number of user multiplexes is greater than the predetermined number, the PHICH is made to be corresponding to the I-channel and the Q-channel.

The invention relates to an instant log output method and device based on an RSA key pair under a Windows platform. The method comprises the following steps that S01, a Main App main application program is started; S02, the Main App acquires a public key file through a network or locally, loads a public key, and establishes a one-way data sending pipeline; S03, the Main App transmits the log data;S04, an application program of the Logger App recorder is started; S05, the Logger App obtains a private key file through a network or locally, loads a private key, and opens a one-way receiving datachannel; and S06, the Loger App receives the log data. The log data are encrypted and decrypted by utilizing the RSA key pair; the log data are transmitted to different places for storage and monitoring in real time through the one-way data transmission channel, the problems that in the prior art, log data transmission is low in safety, data cannot be monitored in real time, and timeliness is loware solved, log data safety is guaranteed, and the timeliness of the log data is improved.

The invention provides a WebSocket-based network speed test method. A data channel is established among client sides and test nodes by the technology, and the total volume of the transmission data andthe total time of the transmission data are calculated so that the data upload rate, the download rate and the delay duration and other information between the client sides and the test nodes can beobtained. Besides, the pc side and the mobile client side are simultaneously supported so that network speed testing of the PC and the mobile equipment under the condition of zero installation and zero configuration can be realized without generating redundant files or influencing the client system.
