Abstract:
1. A wireless communication infrastructure entity comprising: a transceiver; and a controller communicably coupled to the transceiver, the controller configured to generate parity bits based on scheduling grant information, the controller configured to encode the parity bits based on additional scheduling grant information not used to generate the parity bits, wherein a frame within which the scheduling grant information is to be transmitted is indicative of the additional scheduling grant information, wherein the frame is part of a multi-frame structure, and wherein the encoded parity bits are combined with the scheduling grant information; wherein the controller is further configured to encode the parity bits by scrambling the parity bits with a unique set of bits corresponding to the additional scheduling grant information not used to generate the parity bits; wherein the unique set of bits is a mask based on a state of the additional scheduling grant information not used to generate the parity bits; and wherein the controller is further configured to perform the scrambling by XOR-ing the parity bits with the mask.
