Title: DATA SENDING METHOD AND APPARATUS
Abstract:
Embodiments of the present invention relate to the field of communications. Provided are a data sending method and apparatus, which can reduce the number of UEs for retransmitting data, thereby reducing the time delay in sending data on the whole. The method comprises: a base station sends power configuration information to a terminal, the power configuration information comprising a one-to-one correspondence between power information and terminal state information, and the power configuration information being used for enabling the terminal to obtain a transmission power when data is sent; and the base station receives data sent by the terminal, the transmission power of data being determined by the terminal according to the power configuration information, the terminal state information comprising at least one of: the service type of data sent by the terminal, a priority of the data sent by the terminal and information obtained in measuring a wireless environment by the terminal, and the power information comprising at least one of: an expected reception power of the base station, a transmission power of the terminal when communication is performed between the terminal and the base station and the transmission power when the terminal performs D2D communication. The embodiments of the present invention are used for a data sending method based on contention for resources.
