Abstract

A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.

Claims (49)

1 . A method of wireless communication at a user equipment (UE), comprising:

receiving one of a set of repetitions of control information in a 5G New Radio (NR) frame structure scheduling a message;

determining a schedule for receiving the message based on an index associated with receiving the one of the set of repetitions of the control information; and

receiving the message based on the schedule,

wherein the schedule for receiving the message comprises a starting symbol including a portion of the message, and the starting symbol is offset from a first symbol of a slot including the control information.

2 . The method of claim 1 , wherein the index associated with the one of the set of repetitions of the control information comprises a slot index corresponding to a last repetition of the control information.

3 . The method of claim 1 , wherein the schedule for receiving the message comprises a starting symbol including a portion of the message, and the starting symbol is based on the index associated with receiving the one of the set of repetitions of the control information and an offset from the index.

4 . The method of claim 1 , further comprising:

receiving information scheduling a set of monitoring occasions that include the set of repetitions of the control information.

5 . The method of claim 1 , wherein the control information is carried on a physical downlink control channel (PDCCH), and the message is carried on a physical downlink shared channel (PDSCH).

6 . The method of claim 1 , further comprising:

receiving a search space information element (IE) indicating a number of the set of repetitions of the control information.

7 . The method of claim 1 , wherein the message is associated with a random access channel (RACH) procedure and comprises a random access response (RAR) message or a MSG2 message.

8 . A method of wireless communication at a network node, comprising:

transmitting, to a user equipment (UE), a set of repetitions of control information in a 5G New Radio (NR) frame structure scheduling a message from a starting symbol that is based on an index associated with transmitting one of the repetitions of the control information and an offset from the index; and

transmitting, to the UE, the message based on an index associated with transmitting one of the repetitions of the control information,

wherein the offset is from a first symbol of a slot including the control information.

9 . The method of claim 8 , wherein the index associated with the one of the set of repetitions of the control information comprises a slot index corresponding to a last repetition of the control information.

10 . The method of claim 8 , further comprising:

transmitting, to the UE, information scheduling a set of monitoring occasions that include the set of repetitions of the control information.

11 . The method of claim 8 , wherein the control information is carried on a physical downlink control channel (PDCCH), and the message is carried on a physical downlink shared channel (PDSCH).

12 . The method of claim 11 , further comprising:

transmitting, to the UE, a search space information element (IE) indicating a number of the set of repetitions of the control information.

13 . The method of claim 8 , wherein the message is associated with a random access channel (RACH) procedure and comprises a random access response (RAR) message or a MSG2 message.

14 . An apparatus for wireless communication at a user equipment (UE), comprising:

a memory; and

at least one processor coupled to the memory and configured to:

receive one of a set of repetitions of control information in a 5G New Radio (NR) frame structure scheduling a message;

determine a schedule for receiving the message based on an index associated with receiving the one of the set of repetitions of the control information; and

receive the message based on the schedule,

wherein the schedule for receiving the message comprises a starting symbol including a portion of the message, and the starting symbol is offset from a first symbol of a slot including the control information.

15 . The apparatus of claim 14 , wherein the index associated with the one of the set of repetitions of the control information comprises a slot index corresponding to a last repetition of the control information.

16 . The apparatus of claim 14 , wherein the schedule for receiving the message comprises a starting symbol including a portion of the message, and the starting symbol is based on the index associated with receiving the one of the set of repetitions of the control information and an offset from the index.

17 . The apparatus of claim 14 , wherein the at least one processor is further configured to:

receive information scheduling a set of monitoring occasions that include the set of repetitions of the control information.

18 . The apparatus of claim 14 , wherein the control information is carried on a physical downlink control channel (PDCCH), and the message is carried on a physical downlink shared channel (PDSCH).

19 . The apparatus of claim 18 , wherein the at least one processor is further configured to:

receive a search space information element (IE) indicating a number of the set of repetitions of the control information.

20 . The apparatus of claim 14 , wherein the message is associated with a random access channel (RACH) procedure and comprises a random access response (RAR) message or a MSG2 message.

21 . An apparatus of wireless communication at a network node, comprising:

a memory; and

at least one processor coupled to the memory and configured to:

transmit, to a user equipment (UE), a set of repetitions of control information in a 5G New Radio (NR) frame structure scheduling a message from a starting symbol that is based on an index associated with transmitting one of the repetitions of the control information and an offset from the index; and

transmit, to the UE, the message based on an index associated with transmitting one of the repetitions of the control information,

wherein the offset is from a first symbol of a slot including the control information.

22 . The apparatus of claim 21 , wherein the index associated with the one of the set of repetitions of the control information comprises a slot index corresponding to a last repetition of the control information.

23 . The apparatus of claim 21 , wherein the at least one processor is further configured to:

transmit, to the UE, information scheduling a set of monitoring occasions that include the set of repetitions of the control information.

24 . The apparatus of claim 21 , wherein the control information is carried on a physical downlink control channel (PDCCH), and the message is carried on a physical downlink shared channel (PDSCH).
