  • Publication number: 20160056934
    Abstract: Provided are a transmitting or receiving processing method and apparatus for data channel. The transmitting method applied to a base station comprises: acquiring data to be transmitted; transmitting, on multiple sub-frames, the data to be transmitted born by the data channel, wherein the data channel at least comprises two parts, and the number of pilot frequency symbols contained in the first part is larger than that in the second part; and/or, the first part is used for transmitting auxiliary demodulation data and the second part is used for transmitting target data. The technical problems that the accuracy of channel estimation is poor, the coverage performance is low and the like when the original uplink and downlink data transmission way is adopted are solved. The accuracy of coherence demodulation of the target data at a receiving end is ensured, and the coverage performance of the data channel is improved.

  • Publication number: 20150358996
    Abstract: Provided are a method and device for sending control information and receiving control information. The method for sending control information comprises repeatedly sending control information within a scheduling period of the control information M times, wherein the scheduling period is the length of N radio frames, N and M are positive integers greater than 1, and N is greater than or equal to M. The disclosure solves the technical problem in the related art that control information cannot be correctly received in a low-coverage environment and thus a terminal cannot normally access a network, achieving the technical effect of accurately receiving the control information so as to ensure that the network can be accessed normally.

  • Publication number: 20150264708
    Abstract: Disclosed is a subframe scheduling method, which includes: a network side configures a transmission mode, wherein the transmission mode includes at least a multi-subframe scheduling transmission way; the network side selects a corresponding control information format according to the transmission mode, transmits Downlink Control Information (DCI) corresponding to the control information format, and then performs subframe scheduling according to the DCI. Further disclosed are a subframe scheduling system, a network device and a terminal. By means of the disclosure, the multi-subframe scheduling can be used under the condition in which user channel state information is relatively stable, thereby being able to reduce control signalling overheads, save system resources and improve the scheduling flexibility.

  • Publication number: 20150256403
    Abstract: Provided are an information transmission method and device. The method includes that: a base station determines that a receiving bandwidth of first User Equipment (UE) is smaller than a system bandwidth or a component carrier accessed by the first UE is of a New Carrier Type (NCT); and the base station transmits downlink data to the first UE within the receiving bandwidth of the first UE according to a preset Radio Frame (RF), preset subframes and/or preset time-domain and frequency-domain resources. By the disclosure, the problem of how to correctly receive downlink information under a downlink narrowband condition in a related art is solved, UE of different types can coexist in a system, and an application range of the system is widened.

  • Publication number: 20150237604
    Abstract: Disclosed is a method for transmitting downlink control information. The method comprises: a base station determining a time domain position and a frequency domain position of an enhanced search space bearing downlink control information, and sending the downlink control information on the time domain position and the frequency domain position. The present invention further discloses an apparatus for transmitting downlink control information. By means of the solutions in the present invention, the problem that a search space of a PDCCH area cannot be used to transmit downlink control information is solved by transmitting the downlink control information through an enhanced search space when an NCT is independently operated and a low-cost terminal is accessing a large bandwidth system.
