Method and apparatus for receiving or transmitting data
A base station divides a subframe into a downlink time duration for downlink, an uplink time duration for uplink, and a guard period between the downlink time duration and the uplink time duration. The base station transmits a downlink control channel including information on a downlink packet duration allocated for downlink transmission of a terminal and information on an uplink packet duration allocated for uplink transmission of the terminal to the terminal in the downlink time duration.
1. A method of transmitting or receiving data by a terminal in a wireless communication system, the method comprising:
receiving first information on a first list of combinations from a base station through a higher layer signaling, each combination indicating a starting symbol and a number of downlink symbol(s) of a downlink data duration;
receiving, from the base station, a physical downlink control channel (PDCCH) including downlink control information (DCI), the DCI including second information which indicates one combination among the first list of combinations, the one combination indicating a starting symbol and a number of downlink symbol(s) of a downlink data duration allocated for the terminal; and
receiving a downlink data during the allocated downlink data duration from the base station, the allocated downlink data duration starting at the starting symbol indicated by the second information and lasting for the number of downlink symbol(s) indicated by the second information.
2. The method of claim 1 , further comprising receiving third information on a second list of combinations from the base station through a higher layer signaling, each combination indicating a starting symbol and a number of uplink symbol(s) of an uplink data duration.
3. The method of claim 2 , wherein the DCI further includes fourth information which indicates one combination among the second list of combinations, the one combination indicating a staring symbol and a number of uplink symbol(s) of an uplink data duration allocated for the terminal.
4. The method of claim 3 , further comprising transmitting an uplink data during the allocated uplink data duration to the base station, the allocated uplink data duration starting at the starting symbol indicated by the fourth information and lasting for the number of uplink symbol(s) indicated by the fourth information.
5. A method for transmitting or receiving data by a base station in a wireless communication system, the method comprising:
transmitting first information on a first list of combinations to a terminal through a higher layer signaling, each combination indicating a starting symbol and a number of downlink symbol(s) of a downlink data duration;
transmitting, to the terminal, a physical downlink control channel (PDCCH) including downlink control information (DCI), the DCI including second information which indicates one combination among the first list of combinations, the one combination indicating a starting symbol and a number of downlink symbol(s) of a downlink data duration allocated for the terminal; and
transmitting a downlink data during the allocated downlink data duration to the terminal, the allocated downlink data duration starting at the staring symbol indicated by the second information and lasting for the number of downlink symbol(s) indicated by the second information.
6. The method of claim 5 , further comprising transmitting third information on a second list of combinations to the terminal through a higher layer signaling, each combination indicating a starting symbol and a number of uplink symbol(s) of an uplink data duration.
7. The method of claim 6 , wherein the DCI further includes fourth information which indicates one combination among the second list of combinations, the one combination indicating a staring symbol and a number of uplink symbol(s) of an uplink data duration allocated for the terminal.
8. The method of claim 7 , further comprising receiving an uplink data during the allocated uplink data duration from the terminal, the allocated uplink data duration starting at the starting symbol indicated by the fourth information and lasting for the number of uplink symbol(s) indicated by the fourth information.
