Method and apparatus for scheduling in a wireless communication system
First Claim
1. A method for configuring subframes in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- receiving an uplink-downlink configuration from a base station,wherein the uplink-downlink configuration indicates each of a plurality of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe, andwherein the special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS);
receiving frame configuration information from the base station;
configuring each of the plurality of subframes in the frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the uplink-downlink configuration and the frame configuration information; and
communicating with the base station using the configured subframes,wherein a subframe indicated as a downlink subframe or a special subframe by the uplink-downlink configuration cannot be indicated as an uplink subframe by the frame configuration information, andwherein a subframe indicated as an uplink subframe by the uplink-downlink configuration can be indicated as a downlink subframe by the frame configuration information.

Abstract
A method and apparatus are provided for configuring subframes in a wireless communication system. A user equipment (UE) receives an uplink-downlink configuration from a base station. The uplink-downlink configuration indicates each of a plurality of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe. The special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS). The UE receives frame configuration information from the base station and configures each of the plurality of subframes in the frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the uplink-downlink configuration and the frame configuration information. The UE communicates with the base station using the configured subframes.

7. A user equipment (UE) comprising:
-
a radio frequency (RF) unit configured to transmit and receive a radio signal; and a processor operably coupled with the RF unit, wherein the processor is configured to; control the RF unit to receive an uplink-downlink configuration from a base station, wherein the uplink-downlink configuration indicates each of a plurality of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe, and wherein the special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS), control the RF unit to receive frame configuration information from the base station, configure each of the plurality of subframes in the frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the uplink-downlink configuration and the frame configuration information, and control the RF unit to communicate with the base station using the configured subframes, wherein a subframe indicated as a downlink subframe or a special subframe by the uplink-downlink configuration cannot be indicated as an uplink subframe by the frame configuration information, and wherein a subframe indicated as an uplink subframe by the uplink-downlink configuration can be indicated as a downlink subframe by the frame configuration information. - View Dependent Claims (8, 9, 10, 11, 12)
