receiving an SPS allocation over the radio frequency air interface;
using an implicit rule to determine a delta value;
determining a periodicity for a multiple periodicity SPS allocation by using the delta value; and
forming a multi-periodicity sub-frame pattern to receive and transmit TDD packets over the air interface.

Abstract
Systems and methods for determining the periodicity for a multiple periodicity SPS allocation using implicit rules for a TDD communications system are disclosed. A communication terminal such as a UE is provided that may determine the periodicity for a multiple periodicity SPS allocation using implicit rules to calculate a delta value to form a long time period and a shorter time period, forming a periodic pattern where the rules depend on the TDD configuration being used. In another embodiment a communication terminal such as a UE is provided that may determine the periodicity for a multiple periodicity SPS allocation using implicit rules to calculate a delta value to form a long time period and a shorter time period forming a periodic pattern, where the rules depend on the TDD configuration being used and the HARQ process being used.
