Systems, methods and devices for radio access technology coordination
User equipment and base stations can enable access to secondary radio access technology (S-RAT), a cross radio access technology (RAT) scheduling between a primary RAT (P-RAT) and a secondary RAT (S-RAT) and/or cross-scheduling in a same RAT with different optimizations and use/partition for different applications (e.g., a regular partition with a carrier resource (referred to as P-RAT) and an additional resource partition/region for device-to-device (D2D) or machine-type-communication (MTC) application (referred to as S-RAT)). Cross-RAT/partition-scheduling can include when S-RAT is scheduled by P-RAT or when P-RAT is scheduled by S-RAT.
1. An apparatus for a user equipment (UE), comprising:
a memory interface to send or receive, to or from a memory device, a value of an indicator field; and
one or more processors to:
decode a downlink control information (DCI) format to determine the value of the indicator field;
use the value of the indicator field from the DCI format to determine a location of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information in a physical uplink control channel (PUCCH); and
generate the PUCCH with the HARQ ACK information in the location determined from the value of the indicator field in the DCI format.
2. The apparatus of claim 1 , wherein the indicator field comprises a transmission time interval (TTI) index field in the DCI format.
3. The apparatus of claim 1 , wherein the DCI format further includes a partition index.
4. The apparatus of claim 3 , wherein the one or more processors are further to determine, based on the partition index, resources for uplink (UL) transmissions or downlink (DL) receptions.
5. The apparatus of claim 1 , wherein the DCI format further includes a carrier indication.
6. The apparatus of claim 5 , wherein the one or more processors are further to, based on the carrier indication, configure downlink communication.
7. The apparatus of claim 5 , wherein the carrier indication comprises a carrier band index.
8. A non-transitory computer-readable storage medium having computer-readable instructions stored thereon, the computer-readable instructions to, when executed, instruct a processor of a user equipment (UE) to:
decode a downlink control information (DCI) format to determine a partition index value; and
determine, based on the partition index value, resources for uplink (UL) transmissions or downlink (DL) receptions.
9. The non-transitory computer-readable storage medium of claim 8 , wherein the DCI format further includes a carrier indication.
10. The non-transitory computer-readable storage medium of claim 9 , wherein the instructions are further to, based on the carrier indication, configure downlink communication.
11. The non-transitory computer-readable storage medium of claim 9 , wherein the carrier indication comprises a carrier band index.
12. The non-transitory computer-readable storage medium of claim 8 , wherein the DCI format further includes a value of an indicator field.
13. The non-transitory computer-readable storage medium of claim 12 , wherein the instructions are further to, based on the value of an indicator field, determine a location of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information in a physical uplink control channel (PUCCH).
14. An apparatus for a user equipment, the apparatus comprising:
means to determine, from a downlink control information (DCI) format, a carrier field and a partition index value; and
means to determine, based on the partition index value, resources for uplink (UL) transmissions or downlink (DL) receptions.
15. The apparatus of claim 14 , further comprising means to, based on the carrier indication, configure downlink communication.
16. The apparatus of claim 14 , further comprising means to determine, from the DCI format, a value of an indicator field.
17. The apparatus of claim 16 , further comprising means to use the value of the indicator field from the DCI format to determine a location of hybrid automatic repeat request (HARQ) acknowledgement (ACK) information in a physical uplink control channel (PUCCH).
