摘要： Embodiments of the present invention disclose a data transmission method and a terminal. The method includes: detecting, by a terminal in an idle state, whether a logical channel of a first path includes first to-be-transmitted data, and whether a logical channel of a second path includes second to-be-transmitted data; and if it is detected that the logical channel of the first path does not include the first to-be-transmitted data and a length of the second to-be-transmitted data is less than a preset second path transmission data threshold, selecting the second path to transmit the second to-be-transmitted data, where the second to-be-transmitted data includes discontinuously transmitted application data whose length is less than a preset threshold. A dedicated path may be selected to transmit the discontinuously transmitted application data whose length is less than the preset threshold. In this method, network resources may be reduced and data transmission efficiency may be effectively improved.

摘要： Embodiments of the present invention disclose a network selection method, an apparatus and a base station. The method includes: determining each of networks satisfying requirements of a user when the user initiates a service or transmits a service; estimating an average energy efficiency of a system during service transmission after the user selects to access each of the networks; selecting a network which can make the average energy efficiency of the system reach a preset threshold value to serve the user. Embodiments of the present invention solve a problem in the prior art that, because no consideration is given to network energy consumption in the network selection, system energy efficiency is reduced. Through comprehensive consideration of network energy efficiency and system energy efficiency, the need for energy saving and consumption reduction is met.

摘要： Embodiments of the present invention disclose a method and an apparatus for transmitting data in a multiple-antenna system, which are applied in a transmit diversity mode. The method includes: in a data transmission period, determining, according to transmission quality of the system, the number of antennas to be turned off and turning-off time; and in the turning-off time, turning off the determined number of antennas, turning on remaining antennas other than the antennas that are turned off, and transmitting, through the remaining antennas, the data to be transmitted; and during the remaining time of the data transmission period excluding the turning-off time, turning on all antennas and transmitting, through all the antennas, the data to be transmitted. According to the embodiments of the present invention, power consumption may be decreased while at the same time dynamic transmission performance of the system is considered, without an additional scheme design or signaling design and without the need to make any change to a terminal, thus decreasing implementation complexity.
