摘要： A mobile terminal (6) transmits a power supply status signal a network node (4) of a telecommunications network (2), indicating whether or not it is connected to an external power supply. The network (2) may then use this information to adapt one or more parameters, or alter the scheduling of resources, etc. For example, if the mobile terminal (6) is connected to an external power supply, the mobile terminal (6) may be scheduled resources, or parameters adapted such that relatively high power consumption takes place in the mobile terminal (i.e. high transmission power is required, or more frequent monitoring of channels, etc). If the mobile terminal (6) is not connected to an external power supply, the mobile terminal may be scheduled resources, or parameters adapted such that relatively low power consumption takes place in the mobile terminal (i.e. low transmission power is required, or less frequent monitoring of channels, etc).
摘要翻译：移动终端（6）向电信网络（2）的网络节点（4）发送电源状态信号，指示其是否连接到外部电源。然后，网络（2）可以使用该信息来适配一个或多个参数，或改变资源的调度等。例如，如果移动终端（6）连接到外部电源，则移动终端（6）可以是调度资源，或者适应于在移动终端中发生相对高的功率消耗的参数（即，需要高传输功率，或更频繁地监视信道等）。如果移动终端（6）没有连接到外部电源，则移动终端可以是调度资源，或者适于使得在移动终端中发生相对低功耗的参数（即，需要低发射功率，或者较不频繁地监控频道等）。

The user equipment comprises means for controlling a transmission power of the user equipment, such that said transmission power has a first value for a first set of one or more signals sent over a physical channel between the user equipment and the first radio basestation, and a second value for a second set of one or more signals sent over the physical channel between the user equipment and the first radio basestation. The first value and said second value are different. In alternative embodiments, the second set of signals are transmitted taking into account information from the serving cell and a neighbouring cell, while the first set of signals are transmitted taking into account information from the serving cell only.

摘要： According to some embodiments, there is provided a base station, system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL values which ears lead to the UE lowering its output power.
摘要翻译：根据一些实施例，提供了一种基站，系统，其被配置为：（a）检测特定UE是否正在使用太多的功率来发送上行链路数据，以及（b）作为响应，向UE发送消息指示UE检测仅针对特定UE的功率控制RS（PCRS）。在一些实施例中，发送PCRS使得由UE接收的PCRS的功率（实际或标称）高于由UE检测到的先前CRS的功率，从而导致UE计算较低的PL值，其中耳朵导致UE降低其输出功率。
