Description

Method for determining and configuring transmission power, terminal and base station
Technical Field
The present invention relates to the field of communications, and in particular, to a method for determining and configuring transmit power, a terminal, and a base station.
Background
In Long Term Evolution (LTE), a Physical Downlink Control Channel (PDCCH) is used to carry uplink and Downlink scheduling information and uplink power Control information. Downlink Control Information (DCI) format (format) is divided into DCI formats 0, 1A, 1B, 1C, 1D, 2A, 3A, etc., and then, DCI formats 2B, 2C, 2D are added to LTE-a Release 12(LTE-a Release 12) to support various applications and transmission modes. A first communication Node (e-Node-B, abbreviated as eNB) may configure a second communication Node (UE) through downlink control information, or the second communication Node receives configuration of a higher layer (also called as configuring the UE through higher layer signaling).
Uplink power control in a wireless system is very important, and through uplink power control, the UE in a cell can ensure the quality of uplink transmitted data, reduce interference to other users in the system as much as possible, and prolong the service time of a UE battery.
In the LTE/LTE-a system, uplink data between different users in the same cell are orthogonal, so the LTE system adopts slow uplink power control, and mainly considers that uplink transmission adapts to different wireless transmission environments including path loss, shadow fading, and the like through power control. The objects of LTE power control include PUCCH, PUSCH, SRS, and the like. Although the data rate and the importance of these uplink signals are different from each other, the specific power control methods and parameters are different. However, the principle is basically the same, and can be summarized as follows:
the power spectral density (i.e., power per Resource Block (RB)) of the UE transmission is the open loop power control point + dynamic power offset. Here, the open-loop control point is the target power P0+ open-loop path loss compensation α × (PL). The target power P0 is divided into a cell target power and a UE-specific target power.
The open-loop path loss PL is based on the UE path loss estimate for the downlink. The UE measures the Received Power (Reference Signal Received Power, RSRP) of the downlink Reference Signal RSRP Reference Signal, and subtracts the measured Power from the known RS Signal Power, thereby performing path loss estimation.
For PUSCH and SRS, the eNodeB determines the weight of the path loss in the uplink power control of the UE by a parameter path loss compensation factor alpha. For example, for a UE located at a cell edge, if its transmission power is too high, it will cause interference to other cells, thereby reducing the capacity of the whole system. For the PUCCH, since different PUCCH users are code division multiplexed, α is 1, which can better control interference between different PUCCH users.
The dynamic power offset includes two parts, i.e., power adjustment Δ TF based on a Modulation Coding Scheme (MCS) and closed-loop power control. MCS-based power adjustment may cause the UE to dynamically adjust the corresponding transmit power spectral density according to the selected MCS. The closed-loop Power control refers to that the UE adjusts the transmission Power of the UE through a Transmission Power Command (TPC) in the PDCCH. Two ways of adjusting the accumulation and the absolute value can be divided. The accumulative adjustment mode is suitable for PUSCH, PUCCH and SRS, and the absolute value adjustment mode is only suitable for PUSCH. The switching between these two different adjustment modes is semi-static, and the eNB indicates the UE to use an accumulation mode or an absolute value mode through dedicated RRC Radio Resource Control (RRC) signaling.
The accumulation mode is that the current power adjustment value is the adjustment step size indicated in the TPC increased/decreased by the value of the last power adjustment, and the accumulation mode is the adjustment mode used by the UE by default. The TPC in an accumulation mode in LTE can have two sets of different adjustment step sizes, wherein the first set of step size is (-1, 0, 1, 3) dB, and for PUSCH, the first set of step size is indicated by DCI format 0/3; for PUCCH, it is indicated by DCI format 1/1A/1B/1D/2/2A/3. The second set of step sizes is (-1, 1), indicated by DCI format 3a (applicable to PUCCH and PUSCH).
The absolute value scheme is to use the power adjustment value indicated in the TPC directly and apply only to the PUSCH. At this time, the eNodeB needs to explicitly turn off the power adjustment method in the accumulation mode through RRC signaling. When the absolute value mode is adopted, the TPC value is (-4, -1, 1, 4) dB, the DCI format 0/3 indicates that the power adjustment range can reach 8dB, the method is suitable for discontinuous uplink transmission of the UE, and the eNodeB can adjust the transmission power of the UE to a desired value in one step.
With the development of communication technology, the demand of data services is increasing, and available low-frequency carriers are also very scarce, so that communication based on high-frequency (30-300 GHz) carriers which are not fully utilized becomes one of important communication means for solving future high-speed data communication. The available bandwidth for high frequency carrier communication is large, providing efficient high speed data communication. However, one of the great technical challenges facing high frequency carrier communication is: compared with low-frequency signals, high-frequency signals have very large fading in space, and although the problem of spatial fading loss occurs in outdoor communication of the high-frequency signals, more antennas can be generally used due to the reduction of the wavelength of the high-frequency signals, so that the communication can be performed based on beams to compensate the fading loss in space.
However, when the number of antennas increases, the problem of increased cost and power consumption is also caused by the digital beam forming because each antenna needs to have one radio frequency link. Therefore, studies in the related art tend to be more complex beamforming, i.e., the rf beam and the digital beam together form the final beam.
In a research of a New Radio Access Technology (NRAT), a high frequency communication system may configure a large number of antennas to form downlink transmission beams to compensate for spatial fading of high frequency communication in addition to a first communication node, a second communication node may also configure a large number of antennas to form uplink transmission beams, and a side of the first communication node may also select a proper receiving beam to match and receive an uplink signal. In the research of the related art, it has been determined that a beam-specific uplink power control mechanism is adopted, but how to implement flexible and effective configuration to adapt to multiple application scenarios of NRAT is a problem to be solved in uplink power control standardization at present.
In view of the above technical problems in the related art, no effective solution has been proposed at present.
