Abstract: Embodiments of the present invention provide a method for determining a transmission rate supported by a data stream, user equipment, and a base station. The method includes: determining, by user equipment UE, a first index corresponding to an average transmission rate supported by a channel between the UE and the base station; determining, by the UE, a second index corresponding to a difference between an instantaneous transmission rate supported by a data stream on the channel and an average transmission rate supported by the data stream on the channel; sending, by the UE, the first index to the base station; and sending, by the UE, the second index to the base station. According to the embodiments of the present invention, the instantaneous transmission rate supported by the data stream on the channel can be relatively accurately fed back to the base station, thereby improving channel resource utilization.

Abstract: The invention discloses a data transmission method and apparatus. The method determines a target CTU from multiple candidate CTUs according to a first partial identifier in a terminal device identifier, where the terminal device identifier includes the first partial identifier and a second partial identifier. The method sends an uplink data packet to a network device by using the target CTU, where the uplink data packet carries the second partial identifier. According to the data transmission method and apparatus disclosed, the first partial identifier in the terminal device identifier can be implicitly indicated to reduce signaling overheads of a system.

Abstract: A transmission resource mapping method and a device relating to the field of mobile communications technologies, where resource mapping is performed using a resource element block, a length of the resource element block in time domain is less than a length of a physical resource block in the time domain. Therefore, a mapping granularity can be reduced during resource mapping such that latency in a transmission process can be reduced.
