Method and apparatus for transmitting signal in wireless communication system
The present invention relates to a wireless communication system. Specifically, the invention relates to a method and an apparatus for the same, the method comprising the steps of: receiving system information indicating a TDD UL-DL configuration; receiving MBSFN SF allocation information; and, on the basis of a TTI configuration of SF #n, processing a signal for the SF #n, wherein if the SF #n is non-MBSFN SF, the SF #n is configured by a single TTI, and if the SF #n is MBSFN SF, the SF #n is configured by multi-TTI.
1. A method for performing signal processing by a terminal in a wireless communication system, the method comprising:
receiving system information indicating a Time Division Duplex (TDD) uplink-downlink (UL-DL) configuration;
receiving Multicast Broadcast Single Frequency Network (MBSFN) subframe (SF) allocation information; and
performing signal processing for SF #n based on a transmission time interval (TTI) configuration of SF #n, wherein SF #n represents a SF of an index n,
wherein SF #n is configured with a single TTI when SF #n is a non-MBSFN SF, and is configured with multiple TTIs when SF #n is an MBSFN SF, and
wherein each TTI comprises 14 Orthogonal Frequency Division Multiple Access (OFDMA) symbols when SF #n is the non-MBSFN SF, and comprises 3 OFDMA symbols when SF #n is the MBSFN SF.
2. The method according to claim 1 , wherein, when SF #n is the MBSFN SF, SF #n comprises one or more DL intervals and one or more UL intervals corresponding to the multiple TTIs.
3. The method according to claim 1 , wherein, when SF #n is the MBSFN SF, SF #n comprises a plurality of DL intervals corresponding to the multiple TTIs.
4. A terminal used in a wireless communication system, the terminal comprising:
a receiver; and
a processor,
wherein the processor is configured to:
receive, via the receiver, system information indicating a Time Division Duplex (TDD) uplink-downlink (UL-DL) configuration;
receive, via the receiver, Multicast Broadcast Single Frequency Network (MBSFN) subframe (SF) allocation information; and
perform signal processing for SF #n based on a transmission time interval (TTI) configuration of SF #n, wherein SF #n represents a SF of an index n,
wherein SF #n is configured with a single TTI when SF #n is a non-MBSFN SF, and is configured with multiple TTIs when SF #n is an MBSFN SF, and
wherein each TTI comprises 14 Orthogonal Frequency Division Multiple Access (OFDMA) symbols when SF #n is the non-MBSFN SF, and comprises 3 OFDMA symbols when SF #n is the MBSFN SF.
5. The terminal according to claim 4 , wherein, when SF #n is the MBSFN SF, SF #n comprises one or more DL intervals and one or more UL intervals corresponding to the multiple TTIs.
6. The terminal according to claim 4 , wherein, when SF #n is the MBSFN SF, SF #n comprises a plurality of DL intervals corresponding to the multiple TTIs.
