Periodic resource activation and/or release
A wireless device may receive one or more configuration parameters for a cell. The one or more configuration parameters may indicate a periodic resource configuration. The periodic resource configuration may be activatable by predetermined values of: a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and a redundancy version (RV) field of the first DCI format. The wireless device may receive a DCI based on a second DCI format without the HARQ ID field and/or the RV field. The wireless device may activate the periodic resource configuration based on: a size of the HARQ ID field of the DCI and/or the RV field of the DCI being zero; and the periodic resource configuration being in an inactive state.
1. A method comprising:
receiving, by a wireless device, one or more configuration parameters for a cell indicating:
a periodic resource configuration activatable by predetermined values of:
a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and
a redundancy version (RV) field of the first DCI format;
receiving a DCI based on a second DCI format without the HARQ ID field and/or the RV field; and
activating the periodic resource configuration based on:
a size of the HARQ ID field of the DCI and/or the RV field of the DCI being zero; and
the periodic resource configuration being in an inactive state.
2. The method of claim 1 , wherein the DCI is scrambled with a configured scheduling radio network temporary identifier (CS-RNTI) or a semi-persistent channel state information RNTI (sp-CSI-RNTI).
3. The method of claim 1 , wherein the size of the HARQ ID field and the RV field of the DCI is zero.
4. The method of claim 1 , wherein the activating is further based on a new data indicator of the DCI indicating a predetermined value.
5. The method of claim 1 , further comprising determining that the DCI indicates activation of the periodic resource configuration based on:
the size of the HARQ ID field and/or the RV field of the DCI being zero; and
the periodic resource configuration being in the inactive state.
6. The method of claim 1 , further comprising communicating, with a base station, via a resource of the periodic resource configuration.
7. The method of claim 1 , wherein the activating is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being different from a first predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being different from a second predetermined value.
8. The method of claim 1 , wherein the activating is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being different from a first predetermined value and being a same as a third predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being different from a second predetermined value and being the same as a fourth predetermined value.
9. The method of claim 1 , further comprising:
receiving a second DCI; and
releasing the periodic resource configuration based on:
the size of the HARQ ID field and/or the RV field of the second DCI being zero; and
the periodic resource configuration being in an activate state.
10. The method of claim 9 , wherein the activating is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being a same as a first predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being the same as a second predetermined value.
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 one or more configuration parameters for a cell indicating:
a periodic resource configuration activatable by predetermined values of:
a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and
a redundancy version (RV) field of the first DCI format;
receive a DCI based on a second DCI format without the HARQ ID field and/or the RV field; and
activate the periodic resource configuration based on:
a size of the HARQ ID field and/or the RV field of the DCI being zero; and
the periodic resource configuration being in an inactive state.
12. The wireless device of claim 11 , wherein the DCI is scrambled with a configured scheduling radio network temporary identifier (CS-RNTI) or a semi-persistent channel state information RNTI (sp-CSI-RNTI).
13. The wireless device of claim 11 , wherein the size of the HARQ ID field and the RV field of the DCI is zero.
14. The wireless device of claim 11 , wherein the instructions further cause the wireless device to determine that the DCI indicates activation of the periodic resource configuration based on:
the size of the HARQ ID field and/or the RV field of the DCI being zero; and
the periodic resource configuration being in the inactive state.
15. The wireless device of claim 11 , wherein the instructions further cause the wireless device to communicate, with a base station, via a resource of the periodic resource configuration.
16. The wireless device of claim 11 , wherein the activation is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being different from a first predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being different from a second predetermined value.
17. The wireless device of claim 11 , wherein the activation is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being different from a first predetermined value and being a same as a third predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being different from a second predetermined value and being the same as a fourth predetermined value.
18. The wireless device of claim 11 , wherein the instructions further cause the wireless device to:
receive a second DCI; and
release the periodic resource configuration based on:
the size of the HARQ ID field and/or the RV field of the second DCI being zero; and
the periodic resource configuration being in an activate state.
19. The wireless device of claim 18 , wherein the activation is further based on:
a first value of a modulation and coding scheme (MCS) field of the DCI being a same as a first predetermined value; and
a second value of a frequency domain resource assignment field of the DCI being the same as a second predetermined value.
20. A system device comprising:
a base station comprising:
one or more first processors; and
first memory storing instructions that, when executed by the one or more first processors of the base station, cause the base station to:
transmit one or more configuration parameters for a cell indicating:
a periodic resource configuration activatable by predetermined values of:
a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and
