A method for managing uplink transmission, the method comprising: dividing, by a network controller, frequency resources in a single orthogonal frequency division multiplexing, OFDM, symbol into first and second sets of frequency resources, wherein the first set of frequency resources and the second set of frequency resources are interleaved with one another; and signaling, by the network controller, to a user equipment, UE, to transmit data in the first set of frequency resources and to transmit a pilot signal in the second set of frequency resources, characterized in that the method further comprises: instructing, by the network controller, to the UE, to transmit an acknowledgement or negative acknowledgement, ACK/NACK, for a downlink transmission in the single OFDM symbol (650, 670); wherein: when the processing speed of the UE is above a threshold for the UE, and when the processing speed of a network of which the network controller is a component, is below a threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) before a physical uplink shared channel, PUSCH, transmission and a physical uplink control channel, PUCCH transmission, and when the processing speed of the UE is below the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) after the PUSCH and PUCCH transmissions, or when the processing speed of the UE is above the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) in a middle portion of the PUSCH and PUCCH transmissions. dividing, by a network controller, frequency resources in a single orthogonal frequency division multiplexing, OFDM, symbol into first and second sets of frequency resources, wherein the first set of frequency resources and the second set of frequency resources are interleaved with one another; and signaling, by the network controller, to a user equipment, UE, to transmit data in the first set of frequency resources and to transmit a pilot signal in the second set of frequency resources, characterized in that the method further comprises: instructing, by the network controller, to the UE, to transmit an acknowledgement or negative acknowledgement, ACK/NACK, for a downlink transmission in the single OFDM symbol (650, 670); wherein: when the processing speed of the UE is above a threshold for the UE, and when the processing speed of a network of which the network controller is a component, is below a threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) before a physical uplink shared channel, PUSCH, transmission and a physical uplink control channel, PUCCH transmission, and when the processing speed of the UE is below the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) after the PUSCH and PUCCH transmissions, or when the processing speed of the UE is above the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) in a middle portion of the PUSCH and PUCCH transmissions. when the processing speed of the UE is above a threshold for the UE, and when the processing speed of a network of which the network controller is a component, is below a threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) before a physical uplink shared channel, PUSCH, transmission and a physical uplink control channel, PUCCH transmission, and when the processing speed of the UE is below the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) after the PUSCH and PUCCH transmissions, or when the processing speed of the UE is above the threshold for the UE, and when the processing speed of the network is above the threshold for the network, the network controller instructs the UE to transmit the single OFDM symbol (650, 870) in a middle portion of the PUSCH and PUCCH transmissions.
