    • The present invention relates to a method for positioning a user inside a building, wherein the user has a user carried device (100) and the user carried device (100) is provided with a direction sensor (110) and a movement sensor (110). The method comprises the steps of providing the user carried device with a vector map (220) of the building, wherein the vector map (220) comprises vectors and nodes representing possible movement paths for the user in the building; determining a starting point in the vector map representing a first position of the user; receiving movement information from the movement sensor (110) regarding movement of the user in the building; receiving direction information from the direction sensor (110) regarding the direction of the movement of the user; and estimating a new position of the user based on the vector map, the movement information and the direction information.

    • A method is disclosed that includes receiving one or more first localization related measures for a user equipment node at a first localization measurement time, and receiving at least one or more second localization related measures for the user equipment node at a second localization measurement time. The localization related measurements are included in a trace of localization related measurements for the user equipment node from the first localization measurement time to the second localization measurement time. A location for the user equipment at a single time instant in a time interval between the first localization measurement time and the second localization measurement time is estimated from the trace.

    • The present invention compensates for transmit power control time delays between a radio transmitter and receiver that adversely affect the transmit power control process. A time delay associated with a power control loop is compensated for by adjusting a detected signal quality value of a received signal, e.g., signal-to-interference ratio (SIR), based on one or more previous power control commands already sent but whose effect has not yet been experienced. Because the determined signal quality value of the received signal is adjusted based on one or more power control commands already sent but yet to take effect, the transmit power level control command is appropriately determined so that it also takes into account a power control loop time delay. The delay compensation value may be determined based on the output power of a single, previously generated transmit power control command, or on plural previously generated transmit power control commands, depending upon the length of the time delay. If the adjusted signal quality parameter exceeds the target signal quality parameter, the generated power control command directs a decrease in transmit power, and the compensation factor causes a decrease in the subsequently determined signal quality parameter. If the adjusted signal quality parameter is less than the target signal quality parameter, the generated power control command directs an increase in transmit power, and the compensation factor causes an increase in the subsequently determined signal quality parameter.
    • 本发明补偿对发射功率控制过程产生不利影响的无线电发射机和接收机之间的发射功率控制时间延迟。 通过基于已经发送的一个或多个先前的功率控制命令来调整接收信号的检测信号质量值,例如信号干扰比(SIR)来补偿与功率控制回路相关联的时间延迟,但其效果 还没有经验。 由于接收信号的确定的信号质量值是基于一个或多个功率控制命令进行了调整而已经发送但尚未起作用的,所以适当确定发射功率电平控制命令,以便也考虑功率控制环路延时 。 延迟补偿值可以基于单个先前生成的发送功率控制命令的输出功率或者根据时间延迟的长度在多个先前生成的发送功率控制命令上确定。 如果调整后的信号质量参数超过了目标信号质量参数,则生成的功率控制命令指示发送功率的降低,并且补偿因子导致随后确定的信号质量参数的降低。 如果调整后的信号质量参数小于目标信号质量参数,则生成的功率控制命令指示发送功率的增加,并且补偿因素导致随后确定的信号质量参数的增加。
