Abstract:
1. A method for transmission, the method comprising: mapping a plurality of data modulation symbols of a plurality of data packets and a plurality of reference signal symbols into transmission resources of a transmission antenna in accordance with a certain transmission scheme, with the transmission resources being divided into a plurality of subcarriers in a frequency domain and a plurality of time units in a time domain, and within a k-th time unit, N subcarriers being available for transmitting signals, and the N subcarriers comprising N determining bandwidth ratios between respective corresponding pairs of time units for each data packet and power ratios between respective corresponding pairs of time units for each data packet, to maintain a constant bandwidth ratio between each pair of time units across all data packets and a constant power ratio between each pair of time units across all data packets, with the bandwidth ratio η(i,j) between an i-th time unit and a j-th time unit being established for each data packet by: and the power ratio γ(i,j) between an i-th time unit and a j-th time unit for each data packet being established by: where α RS k is a power boosting factor for the reference signal symbols in a k-th time unit; and transmitting the plurality of data modulation symbols of the plurality of data packets and the reference signal symbols via the transmission antenna by using the transmission resources, with the transmission of at least one data packet being in accordance with the determined bandwidth ratios and power ratios.
