A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station, a first radio resource control, RRC, message comprising: a timing offset and information on a start symbol for identifying a resource of a configured periodic grant of a first type, the configured periodic grant of the first type being provided by RRC, a first periodicity of the configured periodic grant of the first type, and a demodulation reference signal parameter of the configured periodic grant of the first type; activating the configured periodic grant of the first type based on the received first RRC message; identifying one or more symbols of the resource of the configured periodic grant of the first type based on the timing offset, the information on the start symbol, and the first periodicity; and transmitting, to the base station, one or more transport blocks based on the activated configured periodic grant of the first type, wherein the method further comprising: receiving, from the base station, a second RRC message comprising a second periodicity of a configured periodic grant of a second type, the configured periodic grant of the second type being provided by a physical downlink control channel, PDCCH; receiving, from the base station, downlink control information, DCI, for a uplink grant; activating, based on the received DCI, the configured periodic grant of the second type which is used for another resource allocation starting from a second symbol allocated based on the DCI, wherein the other resource allocation reoccurring with the second periodicity; identifying one or more symbols of another resource of the configured periodic grant of the second type based on the DCI and the second periodicity; and transmitting, to the base station, one or more other transport blocks based on the activated configured periodic grant of the second type. receiving, from a base station, a first radio resource control, RRC, message comprising: a timing offset and information on a start symbol for identifying a resource of a configured periodic grant of a first type, the configured periodic grant of the first type being provided by RRC, a first periodicity of the configured periodic grant of the first type, and a demodulation reference signal parameter of the configured periodic grant of the first type; a timing offset and information on a start symbol for identifying a resource of a configured periodic grant of a first type, the configured periodic grant of the first type being provided by RRC, a first periodicity of the configured periodic grant of the first type, and a demodulation reference signal parameter of the configured periodic grant of the first type; activating the configured periodic grant of the first type based on the received first RRC message; identifying one or more symbols of the resource of the configured periodic grant of the first type based on the timing offset, the information on the start symbol, and the first periodicity; and transmitting, to the base station, one or more transport blocks based on the activated configured periodic grant of the first type, wherein the method further comprising: receiving, from the base station, a second RRC message comprising a second periodicity of a configured periodic grant of a second type, the configured periodic grant of the second type being provided by a physical downlink control channel, PDCCH; receiving, from the base station, downlink control information, DCI, for a uplink grant; activating, based on the received DCI, the configured periodic grant of the second type which is used for another resource allocation starting from a second symbol allocated based on the DCI, wherein the other resource allocation reoccurring with the second periodicity; identifying one or more symbols of another resource of the configured periodic grant of the second type based on the DCI and the second periodicity; and transmitting, to the base station, one or more other transport blocks based on the activated configured periodic grant of the second type. receiving, from the base station, a second RRC message comprising a second periodicity of a configured periodic grant of a second type, the configured periodic grant of the second type being provided by a physical downlink control channel, PDCCH; receiving, from the base station, downlink control information, DCI, for a uplink grant; activating, based on the received DCI, the configured periodic grant of the second type which is used for another resource allocation starting from a second symbol allocated based on the DCI, wherein the other resource allocation reoccurring with the second periodicity; identifying one or more symbols of another resource of the configured periodic grant of the second type based on the DCI and the second periodicity; and transmitting, to the base station, one or more other transport blocks based on the activated configured periodic grant of the second type.
