| titleOfInvention | D2D user resource distribution method based on multicarrier communication |
| abstract | The invention discloses a D2D user resource distribution method based on multicarrier communication, comprising steps of calculating signal to noise ratio on different subcarriers of each D2D user, distributing a subcarrier to each user according to the calculated signal to noise ratio value to enable the signal to noise ratio of each user to be greatest on the distributed subcarrier, performing distribution on the rest of subcarriers according to the signal to noise ratio of a weighing cellular user and the signal to noise ratio of the D2D user until all the subcarriers are distributed to the users, utilizing a subgradient method to perform iteration on lagrange factors and distributing emission power of the D2D user on each subcarrier in order to ensure the cellular user to meet the requirement of the lowest signal to noise ratio and maximization of D2D user system capacity. The D2D user resource distribution method performs subcarrier distribution on the D2D user on the premise that the cellular user lowest signal to noise ratio is guaranteed and establishes an optimized function which targets maximization of system capacity of the D2D user system and uses the cellular user signal to noise ratio and the D2D user emission power as the constraint condition so as to realize the subcarrier distribution and power distribution of the D2D user. |
