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:
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:
Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.
摘要:
Embodiments of the present disclosure describe closed loop scheduled peak-to-average power (PAPR) reduction systems and methods to facilitate desired PAPR reduction. Other embodiments describe weighted tone reservation (WTR) methods and systems for PAPR reduction. Still other embodiments may be described and claimed.
摘要:
Systems, methods, and devices for device-to-device (D2D) distributed scheduling are disclosed herein. User equipment (UE) is configured to measure a received power level for a reference signal received from a target UE and measure received power levels for reference signals received from one or more non-target UEs. The UE is configured to generate a resource usage map for the target UE and the one or more non-target UEs. The UE is configured to determine a priority, with respect to the target UE, for each resource element group based on the resource usage map and an anticipated signal-to-interference ratio (SIR). The UE is configured to transmit data to the target UE during one or more resource element groups with the highest priorities for the target UE.
摘要:
Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.
摘要:
Embodiments of user equipment and methods for improved uplink transmission power management and scheduling, are generally described herein. For example, in an aspect, a method of uplink power management is presented, the method includes determining whether a total desired transmission power exceeds a total configured maximum output power for a subframe. When the total desired transmission power exceeds the total configured maximum output power, the method includes allocating a minimum proactive power limitation to each serving cell, assigning a remaining power to one or more channels based on priority, and computing a total power assignment based on the allocating and the assigning.
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.
