1. A method for sending downlink control information (DCI), comprising:
obtaining a number of transmission blocks scheduled by the DCI;
determining whether to compress an information field in the DCI based on the number of the transmission blocks by
obtaining an amount of information of the DCI before compression based on the number of the transmission blocks;
determining whether the information field in the DCI needs to be compressed based on a size relationship between the amount of information and a threshold value; and
determining the compressing mode in response to determining that the information field needs to be compressed; and
sending the DCI based on a compressing mode in response to determining to compress;
wherein the compressing mode indicates a compressing strategy of the information field in the DCI;
wherein the compressing strategy comprises
compressing a modulation and coding scheme (MCS) field in the DCI;
wherein compressing the MCS field in the DCI comprises restricting the MCS indicated by the MCS field as at least two MCSs extracted from the MCSs supported by the system based on a designated extracting mode.
