Pre-configured uplink (UL) resource (PUR) start time and offset

1. An apparatus for wireless communications, comprising:

a processor; and

a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to:

output a pre-configured uplink resource (PUR) configuration information comprising a least significant bit (LSB) associated with a hyper system frame number (H-SFN); and

obtain, from a user equipment (UE) at a PUR start time, a first message on a PUR associated with the PUR configuration information, the PUR start time associated with the H-SFN corresponding to the LSB.

2. The apparatus of claim 1 , in which a value of the LSB corresponds to a current LSB associated with a current H-SFN or a previous LSB associated with a previous H-SFN.

3. The apparatus of claim 1 , in which:

the LSB indicates a reference time of an initial downlink message; and

the initial downlink message comprises the PUR configuration information.

4. The apparatus of claim 3 , in which the initial downlink message is a radio resource control (RRC) connection release message.

5. The apparatus of claim 3 , in which retransmissions of the initial downlink message comprise the LSB.

6. The apparatus of claim 1 , in which a value of the LSB corresponds to an H-SFN subsequent to an initial downlink message.

7. The apparatus of claim 1 , in which the PUR configuration information comprises an initial configuration information or reconfiguration information.

8. The apparatus of claim 1 , in which:

execution of the instructions further cause the apparatus to repeat a transmission via a physical downlink shared channel (PDSCH); and

the H-SFN corresponds to a subframe of a set of subframes associated with the repeated transmission.

9. The apparatus of claim 8 , in which the subframe is an initial subframe of the set of subframes or a final subframe of the set of subframes.

10. The apparatus of claim 8 , in which the first message is a data message.

11. An apparatus for wireless communications, comprising:

a processor; and

a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to:

output a first message comprising pre-configured uplink resource (PUR) configuration information; and

obtain, from a user equipment (UE), a second message including a least significant bit (LSB) associated with a hyper system frame number (H-SFN) corresponding to the first message.

12. The apparatus of claim 11 , in which the first message is a radio resource control (RRC) connection release message.

13. The apparatus of claim 11 , in which execution of the instructions further cause the apparatus to output a third message indicating a subframe of the H-SFN, the subframe corresponding to a PUR start time.

14. The apparatus of claim 11 , in which:

the first message is a retransmission of a previous message;

the first message is output via a physical downlink shared channel (PDSCH); and

the H-SFN corresponds to a subframe of a set of subframes associated with the first message.

15. The apparatus of claim 14 , in which the subframe is an initial subframe of the set of subframes or a final subframe of the set of subframes.

16. An apparatus for wireless communications, comprising:

a processor; and

a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to:

output, a first message associated with a hyper system frame number (H-SFN), the first message being a retransmission of a previous message; and

obtain, from a user equipment (UE), a second message on a pre-configured uplink resource (PUR) at a PUR start time associated with the H-SFN, the HSFN being a reference HSFN based on the first message being the retransmission of the previous message.

17. The apparatus of claim 16 , in which:

execution of the instructions further cause the apparatus to output PUR configuration information; and

the second message is obtained in a subframe corresponding to the PUR start time based on the PUR configuration information.

18. The apparatus of claim 16 , in which:

execution of the instructions further cause the apparatus to output a third message indicating a subframe of the H-SFN; and

the subframe is associated with the PUR start time.

19. The apparatus of claim 16 , in which execution of the instructions further cause the apparatus to output a radio resource control (RRC) message indicating the first message is the retransmission of the previous message.

20. The apparatus of claim 16 , in which:

the first message is output via a physical downlink shared channel (PDSCH); and

the H-SFN is associated with a subframe of a set of subframes associated with the first message.

21. The apparatus of claim 20 , in which the subframe is an initial subframe of the set of subframes or a final subframe of the set of subframes.

22. The apparatus of claim 16 , in which the second message is a data message.

23. The apparatus of claim 1 , further comprising:

a transmitter; and

a receiver, in which:

execution of the instructions further cause:

the transmitter to transmit the PUR configuration information, and

the receiver to receive the first message; and

the apparatus is configured as a network node.

24. The apparatus of claim 11 , further comprising:

a transmitter; and

a receiver, in which:

execution of the instructions further cause:

the transmitter to transmit the first message, and

the receiver to receive the second message; and

the apparatus is configured as a network node.

25. The apparatus of claim 16 , further comprising:

a transmitter; and

a receiver, in which:

execution of the instructions further cause:

the transmitter to transmit the first message, and

the receiver to receive the second message; and

the apparatus is configured as a network node.
