A method for processing a serving grant value, comprising: taking, by a user equipment, a maximum value of historical values of a power ratio of a data channel to a control channel as a maximum power ratio value after receiving a non-serving relative grant down command sent by a network device; obtaining, by the user equipment, a first serving grant value according to the maximum power ratio value and a first threshold, wherein the first threshold is a threshold of a serving grant value; taking, by the user equipment, a minimum value among the first serving grant value, a serving grant value of the user equipment before being updated according to the non-serving relative grant down command, and a maximum serving grant value as a serving grant value of the user equipment; wherein the obtaining, by the user equipment, the first serving grant value according to the maximum power ratio value and the first threshold comprises: setting, by the user equipment, a value obtained by subtracting 1 from a serving grant value corresponding to a minimum power ratio value as the first serving grant value when the serving grant value corresponding to the minimum power ratio value is greater than or equal to the first threshold value; wherein the minimum power ratio value is selected, according to a serving grant table, from a power ratio of the data channel to the control channel greater than or equal to the maximum power ratio value. taking, by a user equipment, a maximum value of historical values of a power ratio of a data channel to a control channel as a maximum power ratio value after receiving a non-serving relative grant down command sent by a network device; obtaining, by the user equipment, a first serving grant value according to the maximum power ratio value and a first threshold, wherein the first threshold is a threshold of a serving grant value; taking, by the user equipment, a minimum value among the first serving grant value, a serving grant value of the user equipment before being updated according to the non-serving relative grant down command, and a maximum serving grant value as a serving grant value of the user equipment; wherein the obtaining, by the user equipment, the first serving grant value according to the maximum power ratio value and the first threshold comprises: setting, by the user equipment, a value obtained by subtracting 1 from a serving grant value corresponding to a minimum power ratio value as the first serving grant value when the serving grant value corresponding to the minimum power ratio value is greater than or equal to the first threshold value; wherein the minimum power ratio value is selected, according to a serving grant table, from a power ratio of the data channel to the control channel greater than or equal to the maximum power ratio value. setting, by the user equipment, a value obtained by subtracting 1 from a serving grant value corresponding to a minimum power ratio value as the first serving grant value when the serving grant value corresponding to the minimum power ratio value is greater than or equal to the first threshold value; wherein the minimum power ratio value is selected, according to a serving grant table, from a power ratio of the data channel to the control channel greater than or equal to the maximum power ratio value.
