摘要: Techniques are described that provide uplink power control techniques that can support different uplink multi-input multi-output (MIMO) transmission schemes. A mobile station determines a Signal to Interference-plus-Noise Ratio based on base and offset values transmitted from a base station. The base station can transmit the base and offset values using seven bits total. The mobile station determines an uplink transmitter power level based on the Signal to Interference-plus-Noise Ratio.

摘要: A peak-to-average power ratio (PAPR) reduction method, known as system-aided PAPR reduction (SAPR), is disclosed. Based on a TR algorithm, the SAPR method avoids the drawbacks of conventional tone reservation implementations, and reduces PAPR significantly, in some embodiments. The SAPR method may be applied to next generation OFDMA-based wireless broadband technologies, to increase system throughput and cell coverage.

摘要: A channel normally used to transmit acknowledgement of successful signal receipt and an indication of unsuccessful signal receipt is adopted to transmit power control information from a base station to a mobile station. The power control information can be encoded as a binary code where each value of the code is indicated by an acknowledgement or non-acknowledgement signal.
