Method and apparatus of data transmission in next generation cellular networks
A communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a user equipment (UE) for receiving data is provided. The method includes receiving, from a base station, information on radio resources allocated to the UE, and receiving, from the base station, data based on the information on the radio resources. The radio resources are associated with a plurality of symbols in a time domain and a plurality of resource block groups in a frequency domain. The information on the radio resources includes at least one of first information on a starting symbol, or second information on a size of each of the resource block groups.
1. A method for receiving data by a user equipment (UE), the method comprising:
receiving, from a base station, a radio resource control (RRC) message including a list of a plurality of candidate configurations, each candidate configuration including information on a starting symbol and a number of consecutive symbols counting from the starting symbol for downlink transmission;
receiving, from the base station, downlink control information (DCI) indicating one of the plurality of candidate configurations in the list;
identifying a starting symbol and a number of consecutive symbols counting from the starting symbol of a plurality of symbols allocated to the UE based on the DCI; and
receiving, from the base station, data in the plurality of symbols.
2. A user equipment (UE) for receiving data from a base station, comprising:
a transceiver; and
at least one processor configured to:
receive, from the base station via the transceiver, a radio resource control (RRC) message including a list of a plurality of candidate configurations, each candidate configuration including information on a starting symbol and a number of consecutive symbols counting from the starting symbol for downlink transmission,
receive, from the base station via the transceiver, downlink control information (DCI) indicating one of the plurality of candidate configurations in the list,
identify a starting symbol and a number of consecutive symbols counting from the starting symbol of a plurality of symbols allocated to the UE based on the DCI, and
receive, from the base station via the transceiver, data in the plurality of symbols.
3. A method performed by a base station for transmitting data, the method comprising:
transmitting, to a user equipment (UE), a radio resource control (RRC) message including a list of a plurality of candidate configurations, each candidate configuration including information on a starting symbol and a number of consecutive symbols counting from the starting symbol for downlink transmission;
allocating a plurality of symbols to the UE for downlink transmission;
transmitting, to the UE, downlink control information (DCI) indicating one of the plurality of candidate configurations in the list; and
transmitting, to the UE, data in the plurality of symbols allocated to the UE.
4. A base station, comprising:
a transceiver; and
at least one processor configured to:
transmit, to a user equipment (UE) via the transceiver, a radio resource control (RRC) message including a list of a plurality of candidate configurations, each candidate configuration including information on a starting symbol and a number of consecutive symbols counting from the starting symbol for downlink transmission,
allocate a plurality of symbols to the UE for downlink transmission,
transmit, to the UE via the transceiver, downlink control information (DCI) indicating one of the plurality of candidate configurations in the list, and
transmit, to the UE via the transceiver, data in the plurality of symbols allocated to the UE.
