1. A method for data transmission, comprising:
determining a target logical channel from one or more logical channels according to configuration indication information of a sidelink resource and attribute indication information of the one or more logical channels, wherein the configuration indication information is configured to indicate configuration characteristics of the sidelink resource, and the attribute indication information of each logical channel is configured to indicate whether data on the logical channel requires hybrid automatic repeat request (HARQ) feedback; and
transmitting data on the target logical channel using the sidelink resource,
wherein the configuration indication information is configured to indicate:
information about whether the sidelink resource is configured with a respective physical sidelink feedback channel (PSFCH) resource,
wherein in response to the configuration indication information indicating that the sidelink resource is configured with the respective PSFCH resource, the determining the target logical channel from the one or more logical channels according to the configuration indication information of the sidelink resource and the attribute indication information of the one or more logical channels, comprises:
selecting a logical channel whose attribute indication information indicates requiring HARQ feedback or a logical channel whose attribute indication information indicates requiring no HARQ feedback as the target logical channel,
wherein the selecting the logical channel whose attribute indication information indicates requiring HARQ feedback or the logical channel whose attribute indication information indicates requiring no HARQ feedback as the target logical channel, comprises:
in response to the logical channel whose attribute indication information indicates requiring HARQ feedback and the logical channel whose attribute indication information indicates requiring no HARQ feedback simultaneously existing among the one or more logical channels, and in response to a priority of the logical channel whose attribute indication information indicates requiring HARQ feedback being different from a priority of the logical channel whose attribute indication information indicates requiring no HARQ feedback, selecting the logical channel with a higher priority as the target logical channel.
