Abstract: The present disclosure relates to a terminal device, in which a sending module sends, in a first uplink subframe on a first carrier, an uplink reference signal to a network device, where the first carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink; and a processing module determines a first power headroom PHR, where the first PHR is a PHR of a transmit power of the terminal device in the first uplink subframe or a PHR of a transmit power of the terminal device in the first uplink subframe on the first carrier. Special carriers are introduced, and uplink reference signals are sent on the special carriers, so that information, such as downlink channel characteristics, of these special carriers can be obtained by the network device.

Abstract: In the field of wireless communication technologies, method and apparatus for determining a transport block size (TBS) of a data channel are provided. In a communication network, a terminal device receives control information from a network device. The control information includes modulation indication information and resource information of the data channel. The terminal device determines a modulation order and a code rate according to the modulation indication information, and determines number of time-frequency resources according to the resource indication information of the data channel. The terminal device determines the TBS according to the modulation order, the code rate, and the number of time-frequency resources. Based on the determined TBS, the terminal device decodes the data channel carried on the time-frequency resources or sends the data channel on the time-frequency resources.
