[0042] see figure 2 , is the first embodiment of the power control method of the present invention, which shows the process of performing power control on the UE side:

[0043] Step 201: The UE acquires an aggregated uplink transmit power parameter value, where the aggregated uplink transmit power parameter value is a power parameter value when the UE accesses at least two systems simultaneously.

[0044]Wherein, the UE may configure the aggregated maximum output power as the aggregated uplink transmit power parameter value according to the uplink maximum output power of each system accessing at least two systems, and the aggregated maximum output power is not less than the maximum uplink output power of a single system The maximum value is not greater than the sum of the maximum uplink output power of each system; the aggregate maximum output power can be used as the RF (Radio Frequency, radio frequency) capability of the UE, that is, the aggregate maximum output power can b...

Abstract

The embodiments of the present invention disclose a method, user equipment and network equipment for power control. The method comprises: the user equipment (UE) obtains an aggregate uplink transmission power parameter value, wherein the aggregate uplink transmission power parameter value is the power parameter value of the UE when the UE accesses at least two systems simultaneously; controlling, according to the aggregate uplink transmission power parameter value, the power of UE when it accesses the at least two systems. Because the aggregate uplink transmission power parameter value which refers to the control parameter of the total transmission power of the at least two system is obtained in the embodiments of the present invention, thus uplink power control according to the aggregate uplink transmission power parameter value not only ensure the transmission power of UE to each system, but also avoid excessive radiation of the UE and ensure the quality of service (QoS) characteristics of service.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a power control method, UE (User Equipment, user equipment) and network equipment. Background technique [0002] Current 2G (Second Generation, second generation) communication systems, such as GSM (Global System of Mobile communication, Global System for Mobile Communications) systems, and 3G (Third Generation, third generation) communication systems, such as W-CDMA (Wideband Code Division Multiple Access, broadband code division multiple access) system has been widely deployed in many areas; and with the development of communication technology, LTE (Long Term Evolution, long-term evolution) system, as a new generation evolution network, has also covered some urban areas and traffic hotspots area. It can be seen that in some areas, LTE system, 2G system and 3G system may exist at the same time, and these systems can coexist through macro-micro networking, t...
