Abstract
Provided are a method and an apparatus for communication in a TDD (Time Division Duplex) system. A terminal is notified of a change in a first UL-DL setup from a base station during a first change period and receives a second UL-DL setup updated during a second change period. The terminal refreshes a buffer for an ongoing HARQ (Hybrid Automatic Repeat reQuest) process on the basis of the first UL-DL setup according to the reception of the second UL-DL setup.
Claims14
A communication method in a time division duplex (TDD) system, comprising:
- communicating with a base station by applying a first uplink (UL)-downlink (DL) configuration in which a plurality of DL subframes and a plurality of UL subframes are configured at different times;
- receiving a notification of a change in the first UL-DL configuration from the base station during a first modification period;
- receiving a second UL-DL configuration during a second modification period;
- and
- refreshing a buffer for a hybrid automatic repeat request (HARQ) process on the basis of the first UL-DL configuration upon receiving the second UL-DL configuration.
A user equipment in a time division duplex (TDD) system, comprising:
- a radio frequency (RF) unit for transmitting and receiving a radio signal;
- and
- a processor operatively coupled to the RF unit, wherein the processor is configured for:
- communicating with a base station by applying a first uplink (UL)-downlink (DL) configuration in which a plurality of DL subframes and a plurality of UL subframes are configured at different times;
- receiving a notification of a change in the first UL-DL configuration from the base station during a first modification period;
- receiving a second UL-DL configuration during a second modification period;
- and
- refreshing a buffer for a hybrid automatic repeat request (HARQ) process on the basis of the first UL-DL configuration upon receiving the second UL-DL configuration.
