Abstract

Claims (65)

1. A method of performing preconfigured uplink resource (PUR) transmission using a PUR by a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station, PUR configuration information for the PUR transmission in a Radio Resource Control (RRC) connected state; and

performing the PUR transmission to the base station based on the PUR configuration information in an RRC idle state,

wherein the PUR configuration information includes channel information for an acknowledgement (ACK) or negative-acknowledgement (NACK) transmission from the UE to the base station,

wherein the ACK or NACK transmission is in response to a downlink feedback for the PUR transmission, and the downlink feedback is transmitted from the base station to the UE, and

wherein the downlink feedback corresponds to an uplink transmission using a previous preconfigured uplink resource for the PUR configuration.

2. The method of claim 1 , further comprising:

transmitting, to the base station, the ACK or NACK based on the channel information.

3. The method of claim 1 , wherein:

the channel information is information regarding a channel through which the ACK or NACK is transmitted, and

the channel information includes information regarding a number of repetition of a transmission of the channel.

4. The method of claim 3 , wherein:

the channel information further includes information on a format of the channel and information on a resource index value of the channel.

5. The method of claim 3 , wherein:

the channel is a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

6. The method of claim 1 , wherein:

a transmission power for transmitting the ACK or NACK to the base station is determined by resetting regardless of a transmit power control (TPC) accumulation value.

7. The method of claim 1 , wherein:

the PUR configuration information includes at least one of information on a resource for the PUR transmission, information on a transmission period of the PUR transmission, information related to a transport block size (TBS) for the PUR transmission, or information related to a modulation coding scheme (MCS) for the PUR transmission.

8. A user equipment (UE) configured to perform preconfigured uplink resource (PUR) transmission using a PUR in a wireless communication system, the UE comprising:

at least one transceiver;

at least one processor; and

at least one memory for storing instructions for operations executed by the at least one processor and coupled to the at least one processor,

wherein the operations comprise:

receiving, from a base station, PUR configuration information for the PUR transmission in a Radio Resource Control (RRC) connected state; and

performing the PUR transmission to the base station based on the PUR configuration information in an RRC idle state; and

wherein the PUR configuration information includes channel information for an acknowledgement (ACK) or negative-acknowledgement (NACK) transmission from the UE to the base station,

wherein the ACK or NACK transmission is in response to a downlink feedback for the PUR transmission, and the downlink feedback is transmitted from the base station to the UE, and

wherein the downlink feedback corresponds to an uplink transmission using a previous preconfigured uplink resource for the PUR configuration.

9. The UE of claim 8 , wherein the operations further comprise:

transmitting, to the base station, the ACK or NACK based on the channel information.

10. The UE of claim 8 , wherein:

the channel information is information regarding a channel through which the ACK or NACK is transmitted, and

the channel information includes information regarding a number of repetition of a transmission of the channel.

11. The UE of claim 8 , wherein:

a transmission power for transmitting the ACK or the NACK to the base station is determined by resetting regardless of a transmit power control (TPC) accumulation value.

12. A method of receiving preconfigured uplink resource (PUR) transmission using a PUR by a base station in a wireless communication system, the method comprising:

transmitting, to a user equipment (UE), PUR configuration information for the PUR transmission in a Radio Resource Control (RRC) connected state; and

receiving, from the UE, the PUR transmission based on the PUR configuration information in an RRC idle state,

wherein the PUR configuration information includes channel information for an acknowledgement (ACK) or negative-acknowledgement (NACK) transmission from the UE to the base station,

wherein the ACK or NACK transmission is in response to a downlink feedback for the PUR transmission, and the downlink feedback is transmitted from the base station to the UE, and

wherein the downlink feedback corresponds to an uplink transmission using a previous preconfigured uplink resource for the PUR configuration.

13. A base station configured to receive preconfigured uplink resource (PUR) transmission using a PUR in a wireless communication system, the base station comprising:

at least one transceiver;

at least one processor; and

at least one memory for storing instructions for operations executed by the at least one processor and coupled to the at least one processor,

wherein the operations comprise:

transmitting, to a user equipment (UE), PUR configuration information for the PUR transmission in a Radio Resource Control (RRC) connected state; and

receiving, from the UE, the PUR transmission based on the PUR configuration information in an RRC idle state; and

wherein the PUR configuration information includes channel information for an acknowledgement (ACK) or negative-acknowledgement (NACK) transmission from the UE to the base station,

wherein the ACK or NACK transmission is in response to a downlink feedback for the PUR transmission, and the downlink feedback is transmitted from the base station to the UE, and

wherein the downlink feedback corresponds to an uplink transmission using a previous preconfigured uplink resource for the PUR configuration.

14. An apparatus comprising at least one memory and at least one processor operatively coupled to the at least one memory,

wherein the at least one processor is configured to:

receive, from a base station, preconfigured uplink resource (PUR) configuration information for performing PUR transmission using a PUR in a Radio Resource Control (RRC) connected state; and

perform the PUR transmission to the base station based on the PUR configuration information in an RRC idle state,

wherein the PUR configuration information includes channel information for an acknowledgement (ACK) or negative-acknowledgement (NACK) transmission from the apparatus to the base station,

wherein the ACK or NACK transmission is in response to a downlink feedback for the PUR transmission, and the downlink feedback is transmitted from the base station to the apparatus, and

wherein the downlink feedback corresponds to an uplink transmission using a previous preconfigured uplink resource for the PUR configuration.

15. At least one non-transitory computer-readable medium storing at least one instruction, the at least one instruction executable by at least one processor comprising:

receiving, from a base station, preconfigured uplink resource (PUR) configuration information for performing PUR transmission using a PUR in a Radio Resource Control (RRC) connected state; and

performing the PUR transmission to the base station based on the PUR configuration information in an RRC idle state; and
