Problems solved by technology

Since the transmission block becomes smaller, when the signal quality is good, one transmission block does not need an entire resource block when transmitting data, but now the minimum resource allocation unit for data services is one resource block, which will lead to waste of transmission resources , therefore, there is an urgent need to use transmission resources more rationally for transmission to avoid waste of transmission resources

Embodiment Construction

[0118] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0119] figure 1 It is a schematic structural diagram of a communication system involved in various embodiments of the present invention. see figure 1 , the communication system includes a base station and user equipment (UE, user equipment), where the user equipment is within the coverage of the base station. Wherein, the base station may be an evolved Node B (eNodeB, evolved Node B,), or a home eNodeB (HeNB, home eNodeB), AP, micro base station (micro base station), pico base station (pico base station), etc. Base station equipment for providing communication servers. The user equipment may be called a terminal (terminal), a mobile station (mobile station), a subscriber unit (subscriber unit), a station (station) and so on. The UE...

Abstract

Embodiments of the present invention provide a method and device for transmitting data, which relate to the field of communication technology. The number of F-PRBs, determine the antenna port used to send data to the user equipment; send downlink control information DCI to the user equipment, the transmission format of the DCI is DCI 1A and carry the user equipment allocated F-PRB resource index; sending data to the user equipment through the antenna port. Because the F-PRB resources are smaller than the existing minimum transmission resource block PRB pair resources, when a transmission block does not need a whole resource block, the utilization rate of transmission resources is greatly improved, the waste of transmission resources is avoided, and a A more reasonable way to use transmission resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for transmitting data. Background technique [0002] With the development of 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) and the enhancement of voice coding technology, only a transmission rate of 5.9 kbps is required to achieve the same voice quality as that of a traditional voice service at a rate of 12.2 kbps. The size of the transport block corresponding to the current voice frame (assuming that there is no padding bit) is much smaller than the size of the transport block corresponding to the traditional voice service. Since the transmission block becomes smaller, when the signal quality is good, one transmission block does not need an entire resource block when transmitting data, but now the minimum resource allocation unit for data services is one resource block, which will lead to waste of transmission resour...
