Embodiment 1

[0033] The processing flow of a method for controlling the transmit power of an MS provided in this embodiment is as follows: figure 1 As shown, the following processing steps are included:

[0034] Step 11. Set the power configuration table of the MS in the BS. The power configuration table contains the parameter information of the transmit power of the MS. The parameter information may include: current transmit power, default transmit power, maximum transmit power, minimum transmit power and The power adjustment step information, the above-mentioned maximum transmission power, minimum transmission power, default transmission power and power adjustment step information may be values ​​stipulated in the protocol. The BS sends the above parameter information of the transmit power of the MS to the MS.

[0035] The MS receives the parameter information of the transmit power, calculates the Sounding transmit power of the MS according to the parameter information of the transmit p...

Embodiment 2

[0043] The processing flow of a method for controlling the transmit power of an MS provided in this embodiment is as follows: figure 2 As shown, the following processing steps are included:

[0044] Step 21: Set the power configuration table of the MS in the BS. The power configuration table contains the parameter information of the transmit power of the MS. The parameter information may include: current transmit power, default transmit power, maximum transmit power, minimum transmit power and Power adjustment step size information. The above-mentioned maximum transmission power and minimum transmission power may be fixed values ​​stipulated in the agreement, and the above-mentioned default transmission power may be half of the maximum transmission power or the sum of the minimum transmission power and the maximum transmission power.

[0045] The BS sends the parameter information of the transmit power of the MS to the designated MS through a UL MAP (UpLink Map) message, and...

Abstract

The invention provides a method for adjusting launching power of a subscriber station and a device therefor. The method mainly comprises the steps as follows: Sounding signal sent by the subscriber station is received and carrier wave interference noise ratio (CNIR) of the Sounding signal is obtained; CNIR of the Sounding signal is compared with the preset threshold value; and the launching powerof the subscriber station is adjusted according to the comparison result. The invention can realize the effective control of the launching power of MS on the basis of the Sounding signal sent by the MS and the preset threshold value, so as to control the Sounding launching power of the MS and meet the requirement of Sounding-based channel estimation method.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a device for adjusting the transmission power of a subscriber station. Background technique [0002] A development trend of mobile communication systems is to provide high-speed data transmission to mobile users, so that mobile users can enjoy richer multimedia services. Regardless of whether the mobile users are stationary, slow or moving at high speed, the mobile communication system can communicate with multiple mobile users sequentially or simultaneously by sharing available resources. The mobile communication system mentioned above includes code division multiple access, time division multiple access, frequency division multiple access and other systems. [0003] In a mobile communication system, the modulated signal sent by the transmitter unit can reach the receiver unit through multiple propagation paths. Due to multiple factors such ...
