Abstract
A transmission method includes: a terminal device receives an uplink grant from a base station; and the terminal device sends a report to the base station, where the report includes a power headroom of each of at least one uplink subcarrier, and/or a power headroom of each of at least one bandwidth part. According to the uplink data transmission method, the terminal device, and the base station in embodiments of this disclosure, a power headroom can be reported at a finer granularity.

A method of uplink data transmission that is applied to a multi-connectivity communications system, comprising:
- receiving, by a terminal device, an uplink grant from a base station;
- and
- sending, by the terminal device, a report to the base station, wherein the report comprises one or more of:
- a power headroom of at least one uplink subcarrier;
- and a power headroom of at least one bandwidth part that corresponds to the at least one uplink subcarrier, wherein the report further comprises a plurality of sub reports, each sub report corresponding to each of a plurality of media access control (MAC) entities located in a serving cell of a process in which the terminal device performs multi-connectivity communication, where the plurality of sub reports are sorted in a particular order.
