Adaptive multiple HARQ entity design

Abstract:

Systems and methods for an adaptive multiple Hybrid Automatic Repeat Request (HARQ) entity design to enable dynamic soft buffer sharing between HARQ entities are disclosed. In some embodiments, a transmitter estimates the total buffer consumption of the receiver. In response to determining that there is enough unused space in the soft buffer of the receiver for the new HARQ process of the HARQ entity, the transmitter assigns the new HARQ process of the HARQ entity for data transmission to the receiver. In this way, HARQ entity specific configurations may be enabled while increasing dynamic soft buffer sharing efficiency.
