Configured grant transmission rules
A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a configured grant transmission based on a logical channel. A selection of at least one of: an uplink (UL) or a supplementary UL (SUL) can be configured to be utilized for a CG transmission on an uplink channel based on the selected CG and a consistency test for determining interfering or colliding transmission with the CG transmission.
1. A User Equipment (UE) comprising:
radio frequency (RF) circuitry; and
one or more processors configured to execute instructions stored in a memory to cause the UE to:
receive a configuration of a configured grant (CG) for a physical uplink shared channel (PUSCH);
perform a consistency test to determine whether to configure a CG transmission by applying a set of CG rules for determining a priority of an interfering or a colliding transmission with the CG transmission;
generate a selection of at least one of: an uplink (UL) carrier or a supplementary UL (SUL) carrier based on the consistency test; and
transmit, via the RF circuitry, the CG transmission over the PUSCH based on the selection and the consistency test.
2. The UE of claim 1 , wherein the one or more processors are further configured to:
perform the consistency test based on the CG transmission and one or more other channels/signals detected up to one or more symbols before the CG transmission or a start of an interruption time for the CG transmission.
3. The UE of claim 2 , wherein the one or more symbols comprises a number of L2 symbols, and the consistency test is based on a priority level associated with the one or more other channels/signals.
4. The UE of claim 2 , wherein the interruption time for the CG transmission is based on a time to switch between the UL carrier and the SUL carrier.
5. The UE of claim 4 , wherein the interruption time for the CG transmission is further based on a time of the CG transmission.
6. The UE of claim 4 , wherein the interruption time is further based on whether the UL carrier or the SUL carrier was utilized prior to the CG transmission, and whether the UL carrier or the SUL carrier is selected for the CG transmission.
7. The UE of claim 1 , wherein the set of CG rules comprises priority levels associated with the CG transmission and other signals/channels.
8. The UE of claim 7 , wherein the one or more processors are further configured to:
configure the CG transmission and interrupt another channel/signal transmission based on a lower priority level of the another channel/signal transmission relative to the CG transmission.
9. The UE of claim 1 , wherein the one or more processors are further configured to:
reduce a duration of the CG transmission based on a time duration parameter in response to the CG transmission at least a partially temporally overlapping another channel/signal with a higher priority than the CG transmission.
10. The UE of claim 9 , wherein the one or more processors are further configured to:
communicate the reduced duration of the CG transmission via uplink control information (UCI).
11. A baseband processor configured to, when executing instructions stored in a memory, perform operations comprising:
processing a configuration of a configured grant (CG) for a CG transmission over a physical uplink shared channel (PUSCH);
performing a consistency test to determine a priority of an interfering or a colliding transmission with the CD transmission;
selecting at least one of: an uplink (UL) carrier or a supplementary UL (SUL) carrier for the CG transmission based on the consistency test; and
providing, to a radio frequency (RF) interface, the CG transmission for transmission by RF circuitry over the PUSCH based on the selection and the consistency test.
12. The baseband processor of claim 11 , wherein the operations further comprise:
performing the consistency test based on the CG transmission and one or more other channels or signals that is detected up to a number of L2 symbols before a start of an interruption time for the CG transmission.
13. The baseband processor of claim 12 ,
wherein the interruption time is based on a CG transmission time, and a switching time between the UL carrier and the SUL carrier.
14. The baseband processor of claim 11 , wherein the selection is further based on an information element (IE) that indicates whether the UL carrier or the SUL carrier are allowed for a logical channel associated with the CG transmission.
15. The baseband processor of claim 11 , wherein the operations further comprise:
determining a candidate CG transmission set based on the consistency test; and
selecting the CG for the CG transmission from the candidate CG transmission set.
16. The baseband processor of claim 11 , wherein the operations further comprise:
reducing a duration of the CG transmission in response to the CG transmission at least a partially temporally overlapping with another channel or signal with a higher priority than the CG transmission.
17. A baseband processor configured to, when executing instructions stored in a memory, perform operations, the operations comprising:
generating a configuration of a configured grant (CG) via a logical channel; and
enabling a selection of at least one of: an uplink (UL) or a supplementary UL (SUL) to be utilized for a CG transmission on an uplink channel based on the CG configuration and a consistency test for determining an interfering or colliding transmission with the CG transmission.
18. The baseband processor of claim 17 , wherein the operations further comprise:
providing an indication of one or more priority levels corresponding to one or more other channels or signals, wherein the consistency test is based on the one or more priority levels.
19. The baseband processor of claim 17 , wherein the consistency test is based on an interruption time for providing the CG transmission and at least one switching time between the UL and the SUL.
20. The baseband processor of claim 17 , wherein the operations further comprise:
blind-decoding a change of a time duration parameter for the CG transmission; or
determining the change of the time duration parameter based on uplink control information (UCI) received via the uplink channel.
