Establishing slot boundaries of slots of a diversity control feedback signal
View Patent ↗Establishing slot boundaries includes receiving a feedback signal reflecting feedback information describing a signal modified according to a diversity parameter adjustment. The feedback signal includes slots and bits. A slot boundary is established for each of the slots by: partitioning the bits into periods; comparing the bits of each period; and establishing the slot boundaries in accordance with the comparison.
