Problems solved by technology

[0004] In the process of realizing the narrowband mode and the broadband mode between the UE and the base station, since the current narrowband system does not have a perfect transmission power control mechanism, when the data transmission is realized at a higher power, it will often cause serious interference to the data transmission , or even block directly, which will have a serious impact on the operation of the system
Moreover, due to the poor effectiveness of the transmission power control of the narrowband system, it is easy to cause the UE to transmit data with unnecessary power, thereby causing unnecessary waste of UE power and reducing its standby time

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions of each exemplary embodiment provided by the present invention with reference to the accompanying drawings in the embodiments of the present invention. It should be noted that, in the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] see figure 1 , is a transmission power control method according to an embodiment of the present invention. The method for controlling transmission power may include steps S11, S12 and S13.

[0021] S11: Obtain a path loss parameter when the channel is in a narrowband mode, where the narrowband mode is a communication mode in which the channel between the UE and the base station uses a narrowband to transmit data.

[0022] S12: Select a corresponding power adjustment parameter according to the path loss parameter, and use the selected power adjustment parameter to adjust the power reference value...

Abstract

The present invention discloses a transmission power control method and a user equipment. A power reference value adjusted is compared with a maximum transmission power of a channel in a narrowband mode, and a minimum value between the two is selected as the transmission power in the narrowband mode to avoid data from being transmitted by a higher power in the narrowband mode, so as to effectively reduce the interference to data transmission during coexistence of the narrowband mode and a wideband mode, improve the effectiveness of transmission power control in the narrowband mode, and prolong the standby time of the user equipment to the greatest extent.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a transmission power control method and user equipment. Background technique [0002] The private network trunking communication system is a special communication system with dispatching capability, which can provide a one-way call capability and allow a UE (User Equipment, User Equipment) to communicate with one or more other UEs. With the increasing abundance of mobile services and the rapid growth of business volume, text, pictures, and videos have become one of the communication contents of private network trunking. Traditional narrowband trunking systems, such as PDT (Public Digital Trunking, public digital trunking) systems, due to data Limitations such as weak bandwidth capabilities and poor mobility have made it difficult to meet today's communication needs. Based on this, LTE (Long Term Evolution, Long Term Evolution) technology, whic...
