Channel or signal sending method and apparatus, and storage medium

A channel or signal sending method, being applied to a dual connection scenario or a carrier aggregation scenario and comprising:

• scheduling a first transmission sent on a first carrier or a first carrier group (CG), and scheduling a second transmission sent on a second carrier or a second carrier group;
• wherein transmission time of the first transmission overlaps transmission time of the second transmission;
• in a case where a transmission direction configuration of the first carrier or the first carrier group indicates that an uplink transmission is sent within the transmission time of the first transmission, sending, by a terminal, the first transmission, and canceling sending of the second transmission or sending the second transmission with reduced power;
• or
• in a case where a transmission direction configuration of the first carrier or the first carrier group does not indicate that an uplink transmission is sent within the transmission time of the first transmission, performing, by a terminal, at least one of the following modes:
• sending the first transmission, and canceling sending of the second transmission or sending the second transmission with reduced power;
• sending the second transmission, and canceling sending of the first transmission or sending the first transmission with reduced power;
• determining, by the terminal, whether to send the first transmission or the second transmission;
• determining, according to higher layer signaling configured by a base station, whether to send the first transmission or the second transmission;
• or
• determining, according to a transmission type of the first transmission, a transmission type of the second transmission, and rule 1 configured by a base station, whether to send the first transmission or the second transmission;
• wherein the method further comprises:
• determining, by the terminal, a priority of a transmission channel or signal according to at least one of the following pieces of information:
• transmission time of the transmission channel or signal;
• a transmission direction configuration of a CG;
• whether a CG where the transmission channel or signal is located is a main carrier group (MCG) or a secondary carrier group (SCG);
• whether a CG where the transmission channel or signal is located is LTE or NR;
• a terminal capability type;
• a time domain pattern of a transmission priority;
• a time domain pattern of an uplink power threshold;
• a transmission type of the transmission channel or signal;
• a terminal implementation mode;
• or
• a determination rule configured by a base station.
