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:
Techniques are described that provide uplink power control techniques that can support different uplink multi-input multi-output (MIMO) transmission schemes. Open and closed loop power control schemes can be used to prescribe the power level of the mobile station.
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.
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:
A system and method for wireless wide area network (WWAN) assisted proximity wireless local area network (WLAN) peer-to-peer (P2P) connection and offloading is disclosed. The method includes the operation of identifying a first wireless device and a second wireless device between which a WLAN P2P connection is desired. Each wireless device can have a WWAN radio and a WLAN radio. WLAN information can be sent for at least one of the first and second wireless devices via the WWAN to a P2P configuration server. A WLAN P2P configuration can be received from the P2P configuration server at the first and second wireless devices via the WWAN for WLAN P2P communication between the first and second wireless devices. A WLAN P2P connection can be set up between the first and second wireless devices using the WLAN P2P configuration. The first and the second wireless devices can communicate using the WLAN P2P connection.
摘要:
A method and apparatus for wireless location tracking by a wireless device. In one embodiment of the invention, the wireless device has logic to determine the information of a plurality of specific location points and to determine the location of the wireless device based on the information of the plurality of specific location points. The specific location points are selected from a target area where the wireless device is located. By selecting the specific location points in the target area, it allows hidden Access Points (APs) or Base Stations (BSs) to be detected and measured and it increases the accuracy of the tracking of the wireless device.

Examples are disclosed for a system to improve wireless spectral efficiency, including a processor, memory coupled to the processor, a radio coupled to the processor, one or more antennas coupled to the radio, wireless logic to be executed on the processor component to process reception of a high-power request for open sharing (ROS) signal by a master wireless receiver from a master wireless transmitter and to process transmission of a high-power confirmation of open sharing (COS) signal to the master wireless transmitter, the high-power COS signal comprising an indication of a desired reduction of transmission power level from high power by the master wireless transmitter, and a timer initiated by the high-power COS signal, the timer to indicate a period of time when the master wireless transmitter and master wireless receiver are enabled for low-power communication.
摘要:
An apparatus may include a transceiver operable to receive a downlink message from a base station for a serving cell, the downlink message allocating a set of control parameters. The apparatus may also include a processor circuit communicatively coupled to the transceiver and an uplink power control module operable on the processor circuit to read the set of control parameters, and apply a signal-to-noise-and-interference (SINR) parameter based on the received set of control parameters to determine physical uplink shared channel (PUSCH) power to be applied for a PUSCH transmission. Other embodiments are disclosed and claimed.
摘要:
A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.
摘要:
Technology for device discovery using a device-to-device (D2D) sounding reference signal (SRS) and device discovery using D2D SRS in a channel measurement group (CMG) is disclosed. In an example, a user equipment (UE) configured for device discovery via a node using the D2D SRS can include a transceiver module. The transceiver module can send a radio resource control (RRC) device discovery request to a node, scan D2D SRS subframes of proximity UEs using D2D SRS triggering, and send feedback to the node of detected D2D SRS information of the proximity UEs. The proximity UE can be located within a same cell as the UE.
