HARQ process in a wireless network
A wireless device receives one or more radio resource control messages comprising first periodic resource allocation configuration parameters comprising a first periodicity parameter of a first periodic resource allocation. Downlink control information indicating activation of the first periodic resource allocation is received. The downlink control information comprises one or more first fields. A transport block associated with a hybrid automatic repeat request (HARQ) process identifier is transmitted via radio resources associated with the first periodic resource allocation. The HARQ identifier is based on the one or more first field and the first periodicity parameter.
1. A method comprising:
receiving, by a wireless device, a radio resource control message comprising a periodicity parameter indicating a number of symbols;
receiving a downlink control information indicating activation of a periodic resource allocation, wherein the downlink control information comprises one or more fields indicating a numerology; and
transmitting a transport block associated with a hybrid automatic repeat request (HARQ) process identifier via radio resources associated with the periodic resource allocation, wherein the HARQ identifier is based on the numerology and the number of symbols.
2. The method of claim 1 , wherein the numerology indicates a symbol duration.
3. The method of claim 2 , wherein the HARQ identifier is based on a floor of: a first parameter based on the symbol duration divided by the number of symbols.
4. The method of claim 1 , wherein the radio resource control message further comprises a radio network temporary identifier.
5. The method of claim 4 , wherein the downlink control information is associated with the radio network temporary identifier.
6. The method of claim 1 , wherein the downlink control information indicates radio resources for transmission of the transport block.
7. The method of claim 6 , wherein the radio resources are determined based on one or more second fields.
8. The method of claim 1 , wherein the downlink control information indicates one or more transmission durations up to a first value.
9. The method of claim 8 , wherein a transmission duration in the one or more transmission durations corresponds to one or more logical channels.
10. The method of claim 1 , wherein:
the periodicity parameter indicates a number of transmission time intervals;
the one or more fields indicate a transmission time interval duration; and
the HARQ identifier is based on a floor of: a first parameter based on the transmission time interval duration divided by the number of transmission time intervals.
11. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive a radio resource control message comprising a periodicity parameter indicating a number of symbols;
receive a downlink control information indicating activation of a periodic resource allocation, wherein the downlink control information comprises one or more fields indicating a numerology; and
transmit a transport block associated with a hybrid automatic repeat request (HARQ) process identifier via radio resources associated with the periodic resource allocation, wherein the HARQ identifier is based on the numerology and the number of symbols.
12. The wireless device of claim 11 , wherein the numerology indicates a symbol duration.
13. The wireless device of claim 12 , wherein the HARQ identifier is based on a floor of: a first parameter based on the symbol duration divided by the number of symbols.
14. The wireless device of claim 11 , wherein the radio resource control message further comprises a radio network temporary identifier.
15. The wireless device of claim 14 , wherein the downlink control information is associated with the radio network temporary identifier.
16. The wireless device of claim 11 , wherein the downlink control information indicates radio resources for transmission of the transport block.
17. The wireless device of claim 16 , wherein the radio resources are determined based on one or more second fields.
18. The wireless device of claim 11 , wherein the downlink control information indicates one or more transmission durations up to a first value.
19. The wireless device of claim 18 , wherein a transmission duration in the one or more transmission durations corresponds to one or more logical channels.
20. The wireless device of claim 11 , wherein:
the periodicity parameter indicates a number of transmission time intervals;
the one or more fields indicate a transmission time interval duration; and
the HARQ identifier is based on a floor of: a first parameter based on the transmission time interval duration divided by the number of transmission time intervals.
