Semi-persistent scheduling grants in heterogeneous networks
First Claim
1. A method for wireless communications, comprising:
- determining resource partitioning information (RPI), having a first periodicity, wherein the RPI includes information that identifies subframes that are usable by a user equipment (UE) and protected due to cooperative partitioning of resources between a serving Node B and one or more non-serving Node Bs;
sending a semi-persistent scheduling (SPS) grant message identifying one or more subframes for scheduled transmissions, wherein the SPS grant message, having a second periodicity, is determined based, at least in part, on the RPI; and
exchanging the scheduled transmissions with the UE according to the SPS grant message.

Abstract
Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.
