Abstract
A method of a network node of a time division duplex (TDD) system is disclosed. The method comprises acquiring a maximum cell synchronization error, determining a number of symbols of a partial uplink subframe (PUSF) based on the maximum cell synchronization error, and transmitting an indication of a PUSF configuration to at least one PUSF capable wireless communication device, wherein the PUSF configuration indicates the determined number of symbols of the PUSF. The method also comprises sending an uplink grant signal to one or more of the at least one PUSF capable wireless communication devices, wherein the uplink grant is for a PUSF immediately preceding another subframe to be used for downlink transmission. Transmitting the indication of the PUSF configuration may comprise broadcasting the indication or including the indication in the uplink grant signal. The method may further comprise receiving an indication of PUSF capability from the at least one PUSF capable wireless communication device, thereby identifying the at least one PUSF capable wireless communication device as PUSF capable. Corresponding computer program product, arrangement and network node are also disclosed.
