Abstract:
1. A wireless communication method comprising: establishing a communication channel between a first terminal and a second terminal, the communication channel being configured to provide wireless communications of more than two terminals; transmitting over the communication channel one or more reference signals from the first terminal to the second terminal within a first time period, each of the one or more reference signals being transmitted at an interval occurring periodically within the first time period and being configured to allow evaluation of a channel condition of the communication channel; receiving a responsive signal from the second terminal, the responsive signal being transmitted when a channel condition estimation of the communication channel exceeds a channel condition threshold, the responsive signal being indicative of the second terminal being ready for a data transmission; allocating a second time period within the first time period for transmission of at least one data packet from the first terminal to the second terminal based on the responsive signal; transmitting the at least one data packet from the first terminal to the second terminal within the second time period; and allowing the second terminal to enter into an operation mode limiting the second terminal's ability to receive or transmit for a power-saving time period within the first time period, wherein the power-saving time period overlaps with the second time period when the transmission of at least one data packet completes or terminates before the end of the second time period.
