1. A data transmission method, comprising:
notifying, by a base station, a user terminal of a semi-persistent scheduling (SPS) period, wherein the SPS period is a short period;
allocating, by the base station, a first SPS resource to the user terminal;
transmitting, by the base station, an activation length parameter to the user terminal, wherein the activation length parameter indicates a quantity of consecutive available subframes in one SPS period; and
receiving, by the base station, data periodically sent by the user terminal, wherein the data is sent based on the SPS period using the first SPS resource, and wherein receiving the data periodically sent by the user terminal comprises:
receiving, by the base station, initially transmitted data and at least one piece of retransmitted data for the initially transmitted data that are sent by the user terminal, wherein the initially transmitted data and the at least one piece of retransmitted data occupy the first SPS resource in consecutive SPS periods, and wherein receiving the initially transmitted data and the at least one piece of retransmitted data comprises:
receiving, by the base station, a quantity of continuous transmission times that is sent by the user terminal, wherein the quantity of continuous transmission times indicates a total quantity of times that the initially transmitted data and the retransmitted data are transmitted.
