Semi-persistent scheduling for transmissions
A user equipment (UE) receives a semi-persistent scheduling (SPS) grant for a set of subframes, the set of subframes including an unavailable subframe. The UE also receives an indication of a pattern of available subframes from a base station. The UE determines a subset of available subframes in the set of subframes based on the SPS grant and the pattern of available subframes and adjusts reception or transmission during the set of subframes based on the subset of available subframes. The UE may postpone or drop reception or transmission during the set of subframes based on the subset of available subframes.

12. The apparatus of claim 7 , further comprising:
means for selecting an option to adjust the reception or transmission during the set of subframes based on an amount of bundling employed, the option comprising at least one of:
postponing a transmission scheduled for the unavailable subframe and for any subframe of the set of subframes that is subsequent to the unavailable subframe;
dropping a transmission scheduled for the unavailable subframe; and
dropping a transmission scheduled that includes transmitting during the unavailable subframe.
13. An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive a semi persistent scheduling (SPS) grant for a set of subframes, the set of subframes including an unavailable subframe;
receive an indication of a pattern of available subframes from a base station;
determine a subset of available subframes in the set of subframes based on the SPS grant and the pattern of available subframes; and

14. The apparatus of claim 13 , wherein the at least one processor is configured to adjust the reception or transmission during the set of subframes to:
postpone a transmission scheduled for the unavailable subframe and for any subframe of the set of subframes that is subsequent to the unavailable subframe.
15. The apparatus of claim 13 , wherein the at least one processor is configured to adjust the reception or transmission during the set of subframes to:
drop a transmission scheduled for the unavailable subframe.
16. The apparatus of claim 13 , wherein the at least one processor is configured to adjust the reception or transmission during the set of subframes to:
drop a transmission scheduled that includes transmitting during the unavailable subframe.
17. The apparatus of claim 13 , wherein the at least one processor is configured to adjust the reception or transmission during the set of subframes to:
drop a scheduled transmission that includes transmitting during the unavailable subframe, when the unavailable subframe is a first subframe; and
postpone a transmission scheduled for the unavailable subframe and for any subframe of the set of subframes that is subsequent to the unavailable subframe when the unavailable subframe is after the first subframe.
18. The apparatus of claim 13 , wherein the at least one processor is further configured to:
select an option to adjust the reception or transmission during the set of subframes based on an amount of bundling employed, the option comprising at least one of:
