Abstract
Official abstract text for this publication.
The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a higher data transfer rate beyond a 4G communication system such as LTE. According to the present disclosure, there is provided a method for supporting repetitive transmission of uplink data by a base station in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission comprising repeatedly transmitting uplink data scheduling information in a downlink subframe where an uplink hybrid automatic repeat request (HARQ) process is defined and repeatedly receiving uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive transmitting of the uplink data scheduling information is complete.
First claim
Opening claim text (preview).
1 . A method for supporting repetitive transmission of uplink data by a base station in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission, the method comprising: repeatedly transmitting uplink data scheduling information in downlink subframes where an uplink hybrid automatic repeat request (HARQ) process is defined; and repeatedly receiving uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive transmitting of the uplink data scheduling information is complete. 2 . The method of claim 1 , further comprising: repeatedly transmitting an HARQ-ACK for the uplink data in downlink subframes according to an HARQ transmission timing of an HARQ process defined in an uplink subframe where the repetitive receiving of the uplink data is complete. 3 . The method of claim 1 , wherein the TDD based cell has a UL-DL configuration in which a number of subframes with an HARQ process is greater than a number of subframes without an HARQ process. 4 . The method of claim 3 , wherein the TDD based cell is set to UL/DL configuration #1. 5 . The method of claim 1 , wherein the uplink data scheduling information is not transmitted in a subframe where no uplink HARQ process is defined. 6 . The method of claim 2 , wherein the HARQ-ACK is repeatedly transmitted through one of an enhanced physical downlink control channel (ePDCCH) and an enhanced physical hybrid indicator channel (ePHICH). 7 . The method of claim 1 , before repeatedly transmitting the uplink data scheduling information, further comprising: transmitting information related to the repetitive receiving of the uplink data through a higher layer signaling or L1 layer signal. 8 . A method for performing repetitive transmission of uplink data by a terminal in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission, the method comprising: repeatedly receiving uplink data scheduling information in downlink subframes where an uplink hybrid automatic repeat request (HARQ) process is defined; and repeatedly transmitting uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive receiving of the uplink data scheduling information is complete. 9 . The method of claim 8 , further comprising: repeatedly receiving an HARQ-ACK for the uplink data in downlink subframes according to an HARQ transmission timing of an HARQ process defined in an uplink subframe where the repetitive transmitting of the uplink data is complete. 10 . The method of claim 8 , wherein the TDD based cell has a UL-DL configuration in which a number of subframes with an HARQ process is greater than a number of subframes without an HARQ process. 11 . The method of claim 10 , wherein the TDD based cell is set to UL/DL configuration #1. 12 . The method of claim 8 , wherein the uplink data scheduling information is not received in a subframe where no uplink HARQ process is defined. 13 . The method of claim 9 , wherein the HARQ-ACK is repeatedly received through one of an enhanced physical downlink control channel (ePDCCH) and an enhanced physical hybrid indicator channel (ePHICH). 14 . The method of claim 8 , before repeatedly receiving the uplink data scheduling information, further comprising: receiving information related to the repetitive transmitting of the uplink data through a higher layer signaling or L1 layer signal. 15 . A base station in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission, the base station comprising: a controller controlling an operation of repeatedly transmitting uplink data scheduling information in downlink subframes where an uplink hybrid automatic repeat request (HARQ) process is defined and controlling an operation of repeatedly receiving uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive transmitting of the uplink data scheduling information is complete; and a transceiver repeatedly transmitting the scheduling information and repeatedly receiving the uplink data under the control of the controller. 16 . The base station of claim 15 , wherein the controller is configured to control an operation of repeatedly transmitting an HARQ-ACK for the uplink data in downlink subframes according to an HARQ transmission timing of an HARQ process defined in an uplink subframe where the repetitive receiving of the uplink data is complete. 17 . The base station of claim 15 , wherein the TDD based cell has a UL-DL configuration in which a number of subframes with an HARQ process is greater than a number of subframes without an HARQ process. 18 . A terminal in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission, the terminal comprising: a controller controlling an operation of repeatedly receiving uplink data scheduling information in downlink subframes where an uplink hybrid automatic repeat request (HARQ) process is defined and controlling an operation of repeatedly transmitting uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive receiving of the uplink data scheduling information is complete; and a transceiver repeatedly receiving the scheduling information and repeatedly transmitting the uplink data under the control of the controller. 19 . The terminal of claim 18 , wherein the controller is configured to control an operation of repeatedly transmitting an HARQ-ACK for the uplink data in downlink subframes according to an HARQ transmission timing of an HARQ process defined in an uplink subframe where the repetitive transmitting of the uplink data is complete. 20 . The terminal of claim 18 , wherein the TDD based cell has a UL-DL configuration in which a number of subframes with an HARQ process is greater than a number of subframes without an HARQ process.
