Abstract
Embodiments of the disclosure provide a method and apparatus for enhancing coverage in a TDD system, wherein there is at least one TDD UL/DL configuration for subframes in the TDD system, and the at least one UL/DL configuration comprises at least one special subframe and at least one normal subframe. In the method according to embodiments of the present invention, whether a special subframe is to be applied in TTI bundling is determined first, and then a message with an indication indicating that a special subframe is to be applied in TTI bundling is sent to a UE in response to determining that a special subframe is to be applied in TTI bundling, such that the UE transmits TTI bundling packets on at least one special subframe.
Claims22
A method, at a base station, for enhancing coverage in a Time Division Duplex (TDD) system, wherein there is at least one TDD uplink (UL)/downlink (DL) configuration for subframes in the TDD system, and the at least one UL/DL configuration comprises at least one special subframe and at least one normal subframe, and wherein the method comprises:
- determining whether a special subframe is to be applied in Transmission Time Interval (TTI) bundling;
- in response to determining that a special subframe is to be applied in TTI bundling, sending to a user equipment (UE) a message with an indication indicating that a special subframe is to be applied in TTI bundling, such that the UE transmits TTI bundling packets on at least one special subframe;
- and
- in response to determining that the special subframe is not to be applied in TTI bundling, sending to the UE the message without the indication, such that the UE transmits TTI bundling packets only on normal subframes.
A method, at a user equipment (UE), for enhancing coverage in a Time Division Duplex (TDD) system, wherein there is at least one TDD uplink (UL)/downlink (DL) configuration for subframes in the TDD system, and the at least one UL/DL configuration comprises at least one special subframe and at least one normal subframe, and wherein the method comprises:
- determining whether a message received from a base station (BS) includes an indication indicating that a special subframe is to be applied in Transmission Time Interval (TTI) bundling;
- in response to determining that the received message includes the indication, transmitting TTI bundling packets to the BS on at least one special subframe;
- and
- in response to determining that the received message does not include the indication, transmitting TTI bundling packets to the BS only on normal subframes.
An apparatus for enhancing coverage in a Time Division Duplex (TDD) system, wherein there is at least one TDD uplink (UL)/downlink (DL) configuration for subframes in the TDD system, and the at least one UL/DL configuration comprises at least one special subframe and at least one normal subframe, and wherein the apparatus comprises:
- a first decider configured to determine whether a special subframe is to be applied in TTI bundling;
- and
- a sender configured to, in response to determining that a special subframe is to be applied in Transmission Time Interval (TTI) bundling, send to a user equipment (UE) a message with an indication indicating that a special subframe is to be applied in TTI bundling, such that the UE transmits TTI bundling packets on at least one special subframe,
- wherein the sender is further configured to, in response to determining that a special subframe is not to be applied in TTI bundling, send to the UE the message without the indication, such that the UE transmits TTI bundling packets only on normal subframes.
An apparatus for enhancing coverage in a Time Division Duplex (TDD) system, wherein there is at least one TDD uplink (UL)/downlink (DL) configuration for subframes in the TDD system, and the at least one UL/DL configuration comprises at least one special subframe and at least one normal subframe, and wherein the apparatus comprises:
- a second decider configured to determine whether a message received from a base station (BS) includes an indication indicating that a special subframe is to be applied in Transmission Time Interval (TTI) bundling;
- and
- a transmitter configured to, in response to determining that the received message includes the indication, transmit TTI bundling packets to the BS on at least one special subframe,
- wherein the transmitter is further configured to, in response to determining that the received message does not include the indication, transmit TTI bundling packets to the BS only on normal subframes.
