Time domain resource allocation for PUSCH transmission
The embodiments herein relate to time domain resource allocation for PUSCH transmission. In one embodiment, there proposes a method in a wireless communication device for Random Access (RA), comprising: transmitting a preamble on Physical Random Access Channel (PRACH); receiving a Random Access Response (RAR) message; transmitting, on Physical Uplink Shared Channel (PUSCH), a message for terminal identification (Msg3), wherein the time resource allocation of Msg3 is different than the time resource allocation of other message to be transmitted on the PUSCH (normal PUSCH). The embodiments herein can support flexible time resource allocation configuration for Msg3, and at the same time, the signaling overhead in RAR/DCI for indicating the time resource allocation of PUSCH carrying Msg3 can be reduced.
1. A method of operating a wireless communication device, the method comprising:
transmitting a preamble on a Physical Random Access Channel (PRACH);
receiving a Random Access Response (RAR) message containing an uplink (UL) grant;
transmitting, on a Physical Uplink Shared Channel (PUSCH), a first message wherein the first message is scheduled by the RAR message and has a first time resource allocation; and
transmitting, on the PUSCH, a second message wherein the second message is not scheduled by the RAR message and has a second time resource allocation, the first and second time resource allocations being different by a predetermined timing offset that is based on a numerology.
2. The method of claim 1 , wherein the first message is an Msg3 message and the second message is a non-Msg3 message.
3. The method of claim 1 , wherein the predetermined timing offset corresponds to a numerology according to:
numerology
0
2
offset in unit of slot
2
4.
4. The method of claim 1 , wherein the predetermined timing offset applies to the first time resource allocation.
5. The method of claim 1 , wherein the predetermined timing offset applies to the second time resource allocation.
6. The method of claim 1 , wherein the predetermined timing offset depends on a numerology used, and there is one timing offset for one numerology.
7. The method of claim 1 , wherein the predetermined timing offset depends on a numerology used, and there is more than one timing offset for one numerology.
8. The method of claim 1 , wherein the predetermined timing offset is indicated in the RAR message.
9. A wireless communication device comprising:
a processor; and
a non-transitory computer readable medium in communication with the processor, the non-transitory computer readable medium storing instructions executable by the processor, whereby the processor is configured to perform operations comprising:
transmitting a preamble on a Physical Random Access Channel (PRACH);
receiving a Random Access Response (RAR) message containing an uplink (UL) grant;
transmitting, on a Physical Uplink Shared Channel (PUSCH), a first message wherein the first message is scheduled by the RAR message and has a first time resource allocation; and
transmitting, on the PUSCH, a second message wherein the second message is not scheduled by the RAR message and has a second time resource allocation, the first and second time resource allocations being different by a predetermined timing offset that is based on a numerology.
10. The wireless communication device of claim 9 , wherein the first message is an Msg3 message and the second message is a non-Msg3 message.
11. The wireless communication device of claim 9 , wherein the predetermined timing offset corresponds to a numerology according to:
numerology
0
2
offset in unit of slot

4.
12. The wireless communication device of claim 9 , wherein the predetermined timing offset applies to the first time resource allocation.
13. The wireless communication device of claim 9 , wherein the predetermined timing offset applies to the second time resource allocation.
14. The wireless communication device of claim 9 , wherein the predetermined timing offset depends on a numerology used, and there is one timing offset for one numerology.
15. The wireless communication device of claim 9 , wherein the predetermined timing offset depends on a numerology used, and there is more than one timing offset for one numerology.
16. The wireless communication device of claim 9 , wherein the predetermined timing offset is indicated in the RAR message.
17. A method of operating a wireless communication device, the method comprising:
transmitting a preamble on a Physical Random Access Channel (PRACH);
receiving a Random Access Response (RAR) message containing an uplink (UL) grant;
transmitting, on a Physical Uplink Shared Channel (PUSCH), a first message wherein the first message is a Msg3 message and has a first time resource allocation; and
transmitting, on the PUSCH, a second message wherein the second message is a non-Msg3 message and has a second time resource allocation, the first and second time resource allocations being different by a predetermined timing offset that is based on a numerology.
18. The method of claim 17 , wherein the predetermined timing offset is a number of slots.
