A data transmission method, comprising: determining, by a terminal device, whether there exists a skippable resource in a transmission resource set, which is semi-statically scheduled by a network device, according to reference information, wherein resources in the transmission resource set are Semi-Persistent Scheduling,SPS, resources configured by the network device for the terminal device; receiving, by the terminal device, a Physical Downlink Shared Channel, PDSCH, corresponding to a target service on an available resource in the transmission resource set, and determining not to receive, by the terminal device, the PDSCH, corresponding to the target service on the determined skippable resource in the transmission resource set; wherein the method further comprises: determining, by the terminal device, the skippable resource in the transmission resource set according to a first condition, wherein the first condition comprises that: the terminal device supports not receiving the target service on a part of resources in the transmission resource set; wherein determining, by the terminal device, the skippable resource in the transmission resource set according to the first condition comprises at least one of the following: determining the skippable resource in the transmission resource set according to a period of the target service and a period of the at least one group of periodic transmission resources; or determining the skippable resource in the transmission resource set according to an amount of resources required by the target service and an amount of resources that have been used in the transmission resource set. determining, by a terminal device, whether there exists a skippable resource in a transmission resource set, which is semi-statically scheduled by a network device, according to reference information, wherein resources in the transmission resource set are Semi-Persistent Scheduling,SPS, resources configured by the network device for the terminal device; receiving, by the terminal device, a Physical Downlink Shared Channel, PDSCH, corresponding to a target service on an available resource in the transmission resource set, and determining not to receive, by the terminal device, the PDSCH, corresponding to the target service on the determined skippable resource in the transmission resource set; wherein the method further comprises: determining, by the terminal device, the skippable resource in the transmission resource set according to a first condition, wherein the first condition comprises that: the terminal device supports not receiving the target service on a part of resources in the transmission resource set; wherein determining, by the terminal device, the skippable resource in the transmission resource set according to the first condition comprises at least one of the following: determining the skippable resource in the transmission resource set according to a period of the target service and a period of the at least one group of periodic transmission resources; or determining the skippable resource in the transmission resource set according to an amount of resources required by the target service and an amount of resources that have been used in the transmission resource set. the terminal device supports not receiving the target service on a part of resources in the transmission resource set; wherein determining, by the terminal device, the skippable resource in the transmission resource set according to the first condition comprises at least one of the following: determining the skippable resource in the transmission resource set according to a period of the target service and a period of the at least one group of periodic transmission resources; or determining the skippable resource in the transmission resource set according to an amount of resources required by the target service and an amount of resources that have been used in the transmission resource set. determining the skippable resource in the transmission resource set according to a period of the target service and a period of the at least one group of periodic transmission resources; or determining the skippable resource in the transmission resource set according to an amount of resources required by the target service and an amount of resources that have been used in the transmission resource set.
