In order to improve system performance, link circuit self-adapting, power control etc. are often management function important in communication system. In a communication network, at least one node sends signal to other nodes, and the purpose of power control, be so that in network, by The signal that at least one node is sent, when reaching other nodes, power can satisfy the demand of system.
Here node can refer to base station, user equipment etc..Such as, power control can be, so that user's hair The signal power sent meets certain power requirement when reaching another user.Or such as, power control can be, So that the signal power that user sends meets the power requirement of base station when reaching base station.Or such as, function can be passed through Rate control, so that the signal that base station is sent meets the power demand of user equipment when reaching user equipment.
Power demand in power control can refer to the power demand up to a node, e.g., if signal is to the node It is useful signal, then the node is in need to the power for receiving signal meets the needs of demodulation threshold, which is to receive signal Power should cannot be too low, otherwise lead to not be properly received, demodulate.Alternatively, such as, if the signal is non-useful letter to the node Number, for example interference signal, then the node is in need to the power of the reception signal meets the needs of interference threshold value, which is The power of the reception signal should cannot be too high, otherwise cause the signal to cause stronger interference to the useful signal of the node.
Power control can occur between a node and another node, if D2D scene is for a user equipment Power to another user equipment meets certain Signal Interference and Noise Ratio (signal to interference plus Noise ratio, SINR)；It can also occur between multiple nodes and a node, such as the uplink in LTE, power control is For at least one user equipment allowed in network, the power of base station is reached, the Signal Interference and Noise Ratio SINR need of base station are met It asks；It can also occur in multiple nodes between multiple nodes, such as at time division duplex (time division duplex, TDD) It may be simultaneously present uplink and downlink scheduling (the dynamic TDD technology in such as 5G network) in network formats, in system, at this time power Control can be for the power requirement of the multi-to-multi of multiple user equipmenies, multiple base stations in relational network.
The design of power control is the signal transmitting power for controlling nodes, so that the reception power of the signal, full Foot, which receives, to be required.Here, it receives and requires can be power requirement described above, SINR requirement etc. or signal-to-noise ratio (singal-noise ratio, SNR) requirement.(interference over thermal interferes ratio by SNR, SINR, IoT Heat), RSRP (reference signal received power, Reference Signal Received Power), the reception power of signal etc., The target component in power control link can be regarded as, these parameters are not exclusively of equal value, but interknit.Such as, SINR and RSRP are not completely equivalent, but in the identical situation of interference level, RSRP is higher, it is meant that the SINR of signal is better. Power control herein does not limit the target control parameter of algorithm in practice.But generally, base station can be by comparing system Whether the signal SINR on meter converges to target SINR, to determine the parameter of power control.
Power headroom (PH, power headroom) reports the ring in PHR and power control link.Power control Surplus refers to that node can reach the difference power between maximum transmission power and the power of node one signal of transmission.Here function Rate difference refers to the meaning of the gap between sensu lato power, does not imply that having to is that two power subtract each other to obtain.In practice, The difference power can be obtained by the linear value that the linear value subtraction signal of the maximum power sends power, or by described Decibel (dB) the value subtraction signal of maximum power send decibel (dB) value of power and obtain, be in this case then equivalent to described The linear value of maximum power is reconverted into dB value divided by the result of the linear value of signal transmitting power, and such case is also referred to as power Difference.Therefore correspondingly, the description of the formula occurred in this application is in order to illustrate this physical meaning of difference power, formula sheet Body can also the subtraction of dB value, the division of linear value, linear value subtraction etc. between convert.
PH value can be positive number, 0, negative, its value can be quantified, such as according to a certain amount section, by PH In value quantization to different quantification gradations.
Power headroom reporting (PHR) is to be sent to other nodes by the node of above-mentioned transmission signal.By taking LTE network as an example, User equipment calculates, generates and sends PHR, and the pH value is received, calculated and applied by base station.In LTE, user equipment is meeting Under trigger condition, PHR being triggered, when meeting report condition, UE obtains pH value, and pH value is transmitted to PHR corresponds in cell, Then the PHR is sent by the channel carried.PHR cell is a kind of MAC cell in LTE, and the channel of carrying is PUSCH。
Base station is after receiving PHR, by the PH information etc. in available PHR.Base station can use PH information, Lai Jinhang function The process of rate management.Such as, when the PH for receiving user equipment when base station is smaller (PH is that negative is alternatively referred to as being PH smaller), it is meant that The maximum transmission power that user equipment can be supported has been difficult or cannot support to send current signal.At this moment, base The resource distributed to user equipment can be adjusted by algorithm by standing, and such as reduce the bandwidth that user equipment sends signal, alternatively, base station (specific means are in embodiment for the transmission power of adjustable user equipment, such as the transmission signal power of reduction user equipment In), enable user equipment to send signal, prevents because sending the reality that power demand is excessive and maximum power is not caused enough Border sends power density and is lower than the required power density in base station, and the quality of signal is caused to be deteriorated.It here is one in power control The example that PH is applied in system, in real system, can be designed all kinds of optimization algorithms, be carried out optimization system based on the physical meaning of PH Performance.
The physics process of above-mentioned PHR is not limited to LTE network.The process can also extend, reduce, being embedded into other networks In, such as 5G network.
It in order to simplify subsequent statement, says that power control is known as PC here, power headroom reporting (PHR) process etc. is known as PHR. In a broad sense, PC and PHR is the part process in power control.PC is mainly used for directly controlling the transmission function of terminal device Rate, PHR is come transmission power, the resource etc. that indirectly control terminal device.
Correlation formula in power control and power headroom reporting (PHR) is directed to various uplink signals or channel design.In LTE, Including PUSCH, PUCCH and SRS, in 5G, it can accordingly be directed to uplink data channels, control channel, the ginseng for demodulation Examine signal, the reference signal for channel ginseng survey, channel of random access etc..Correlation formula resource granularity calculated is One resource collection contains more than one least resource granularity in resource collection.Resource collection can in the angle of time domain To be one or more in system-frame, radio frames, frame, subframe, time slot, half slot, mini time slot, symbol, assemble of symbol etc..
