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 weighted tone reservation (WTR) method and system are disclosed, for PAPR reduction. The WTR method solves the peak re-growth problem with minimum overhead. By avoiding the drawbacks of conventional tone reservation approaches, systems employing the WTR method may experience a significant PAPR reduction. The WTR method may be applied to next generation OFDMA-based wireless broadband technologies to increase system throughput and cell coverage.

摘要:
Uplink power control in a macro cell in a wireless network comprises transmitting a reference signal from a base station device to at least one wireless device within the macro cell. The macro cell comprises the base station device and at least one radio transmitter device that is communicatively coupled to and remote from the base station device. The base station device and one or more radio transmitter devices could be selected to be a transmission point, a reception point or a combination thereof, for each wireless device. Information relating to a transmission power of the base station device is also transmitted to the at least one wireless device. An uplink signal is received from the at least one wireless device containing information relating to an uplink power determination that is based on the reference signal and the information relating to the transmission power of the base station device.
摘要:
Provided are systems and methods for polling, by a wireless network access point, a group of wireless network stations for an uplink transmission status, receiving (from one or more wireless network stations of the group of wireless network stations) an uplink transmission status report indicating that the wireless network station is ready for uplink data transmission, scheduling (in response to receiving the one or more uplink transmission status reports) one or more uplink data transmissions from the one or more wireless network stations, and receiving (from the one or more wireless network stations in accordance with the scheduling) one or more uplink data transmissions comprising uplink data.
摘要:
A user equipment (UE) is arranged to send an uplink power reference signal to an enhanced Node B (eNB) associated with multiple reception points (RPs), to receive identification of an RP set and a downlink reference signal power level, to determine a path loss estimate for each downlink reference signal received from RPs of the RP set, to determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the RP set, and to use the determined uplink power level during communication with the multiple RPs.
摘要:
Embodiments of the present disclosure provide methods, systems, and apparatuses related to a partially random permutation sequence generator. In embodiments, a partially random permutation may provide a large distance between neighboring elements while keeping a degree of randomness in the distribution. In some embodiments, it may be applied to distribute resource units across subchannels to provide frequency diversity and/or diversity gain in OFDMA-based wireless broadband technologies. Other embodiments may be described and claimed.
