Repetition And Hybrid Automatic Repeat Request Process Determination For Grant-Free Transmission In Mobile Communications

A method, comprising:

• receiving, by a processor of an apparatus, a data repetition with a repetition index;
• determining, by the processor, a hybrid automatic repeat request (HARQ) process identifier (ID) according to the repetition index and a repetition pattern;
• and
• decoding, by the processor, data according to the HARQ process ID,
• wherein the reference signal is used to identify the repetition index of the data repetition.

An apparatus, comprising:

• a transceiver capable of wirelessly communicating with a plurality of nodes of a wireless network;
• and
• a processor communicatively coupled to the transceiver, the processor capable of:
• determining a cyclic shifted version of a base sequence;
• generating a reference signal;
• and
• transmitting, via the transceiver, a data repetition along with the reference signal on a semi-persistent scheduling (SPS) resource to a network node,
• wherein the reference signal is used to identify a repetition index of the data repetition.

An apparatus, comprising:

• a transceiver capable of wirelessly communicating with a plurality of user equipment of a wireless network;

• receiving, via the transceiver, a data repetition with a repetition index;
• determining a hybrid automatic repeat request (HARQ) process identifier (ID) according to the repetition index and a repetition pattern;
• and
• decoding data according to the HARQ process ID,
• wherein the reference signal is used to identify a repetition index of the data repetition.
