no. 1 approach

[0036] Step 102: After receiving the wireless power, it is determined that at least one communication peer requires adjustment of the quality of the signal received by the communication peer;

[0037] Step 103: Determine the power required by the communication peer for the signal it receives;

[0038] Step 104: Adjust the transmission power according to the above determined required power.

[0039] From the above embodiments, it can be seen that since the communication parties agree on the time slots for transmitting and receiving wireless power, that is, when one party transmits wireless power in a predetermined time slot, the other party receives the wireless power in this predetermined time slot. After the power is determined, it is determined that at least one communication peer requires adjustment of the quality of the signal received by the communication peer, so the required power can be determined and then the transmission power can be adjusted according to this power ...

no. 3 approach

[0061] Step 402: Reduced transmit power.

[0062] This embodiment is mainly to reduce the transmission power of the device, that is, when no wireless power transmitted from the communication peer is received within a predetermined time, it is considered that the current transmission power of the device has exceeded the requirements of all communication peers. At this time, reduce the forward power by one unit and lower the transmit power.

[0063] refer to Figure 5 , the present invention provides a fourth implementation mode of a power control method. This implementation mode introduces the process of the power adjustment requesting party, including the following steps:

[0064] Step 501: Receive a wireless signal transmitted by a communication peer;

[0065] Step 502: According to the quality of the received wireless signal, determine whether it is necessary to request the communication peer to adjust transmission power;

[0066] Step 503: Transmit wireless power in a pr...

Abstract

This invention discloses a method for controlling power and radio equipment, in which, the method includes: receiving a radio power emitted by a communication opposite end at a scheduled time slot to judge out at least one opposite end demands to adjust quality of the signal received by the end and confirms the power needed by the end to the received signal to adjust emission power according to the demanded power.

Description

technical field [0001] The invention relates to the communication field, in particular to a power control method and a wireless device. Background technique [0002] In wireless communication technology, the air interface channels of a general trunking system include: [0003] CH1: Reverse channel. The mobile phone that has obtained the right to speak transmits its own business and signaling on this channel. This channel is a dedicated channel. It is specially provided for mobile phones that have obtained the right to speak. [0004] CH2: reverse channel, the mobile phone that has not obtained the speaking right sends reverse signaling (such as speaking right application) on this channel, and this channel is a public channel. Provided to all mobile phones that do not have the right to speak. [0005] CH3: Forward channel, the system sends public signaling on this channel, which is a public channel. All mobile phones entering the PTT business state can monitor. [0006] ...
