Efficient Bitmap Signaling for VoIP in OFDMA
The communication system is currently undergoing a convergence to IP services. As a result, Voice over Internet Protocol (VoIP) will be commonplace in the near future. In order to maximize the voice capacity, the overhead associated with controlling VoIP transmissions must be carefully managed. The current efforts in B3G (Beyond 3G) standards development to efficiently control VoIP transmissions by grouping VoIP users into scheduling groups, assigning the group a set of shared time-frequency resources, and using bitmap signaling to allocate resources were detailed.
