A method, network device and computer readable storage media can provide joint allocation of transmission power and time resource in a dynamic Time Division Duplex (TDD) communication system. In example embodiments, a minimum time resource assignment of uplink and downlink transmissions required by their respective given traffic demands under a given time resource configuration and a given bandwidth configuration is determined for terminal devices served by a network device. An optimal time resource assignment of the uplink and downlink transmissions is determined under the given bandwidth configuration based on the minimum time source assignment by means of an optimal incremental method. An optimal transmission power assignment of the uplink and downlink transmissions is determined based on the optimal time resource assignment. A joint allocation of transmission power and time resource can thus be implemented, which could minimize transmission power over the allocated time resource while meeting given traffic demands.
