Abstract

An embodiment of the present invention provides a DCI format information transmission method, related equipment, and system, the method including: allocating a resource block RB for sending a demodulation reference signal DMRS sequence; sending the first DCI format information to a first user terminal, Wherein, the first DCI format information includes a bandwidth segment indication and a resource allocation indication, the bandwidth segment indication is used to indicate the bandwidth segment to which the RB belongs, and the resource allocation indication is used to indicate that the RB is in the bandwidth segment position or sequence number. The implementation of the present invention can reduce the overhead of DCI format information.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for transmitting information in a downlink control information format (Downlink Control Information format, DCI format), related equipment and a system. Background technique [0002] In the current communication system, the demodulation reference signal (DeModulation Reference Signal, DMRS) used by the user terminal for demodulation in the downlink is independently configured by each user terminal at each transmission, and the DMRS occupies a bandwidth of The bandwidth allocated for transmission. In addition, the parameter configuration of DMRS is realized by DCI format information. For example: the DCI format information includes a resource allocation indication, which is used to indicate the resource block (Resource Block, RB) used for sending DMRS. [0003] However, in future communication systems (such as 5G systems), the highest bandwidth in a c...
