Description

Information interaction method and device between communication nodes
Technical Field
The invention relates to the field of communication, in particular to an information interaction method and device between communication nodes.
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, the DCI formats 2B, 2C, 2D are added to LTE-a release 12 (LTE-area 12) to support various applications and transmission modes. A base station (eNB, e-Node-B) may configure a terminal (UE) through downlink control information, or the terminal receives configuration of higher layers (also called UE is configured 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 importance of these uplink signals are different, their specific power control methods and parameters are also different. However, the principle is basically the same, and can be summarized as follows:
the power spectral density of the UE transmission (i.e., power per RB (resource block)) = open loop industrial control point + dynamic power offset. Wherein, the open-loop industrial control point = 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 performs path loss estimation by measuring the Received Power (Reference Signal Received Power, RSRP for short) of the downlink Reference Signal RSRP and subtracting the Signal Power from the known RS (how much Power is used when the Reference Signal base station sends, and notifying the terminal through signaling) Signal Power.
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 can be divided into accumulation adjustment and absolute value adjustment. 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. 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, DCI format 1/1A/1B/1D/2/2A/3 indicates. 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, 4) dB, the DCI format 0/3 indicates that the power regulation range can reach 8dB, the method is suitable for discontinuous uplink transmission of the UE, and the eNodeB can further regulate the transmission power of the UE to an expected value.
With the development of communication technology, the demand of data services is increasing, and available low-frequency carriers are very scarce, so that communication based on a high-frequency (30-300 GHz) carrier which is 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: the high frequency signal has very large fading in space relative to the low frequency signal, which may cause the problem of fading loss in space in outdoor communication of the high frequency signal, but due to the reduction of the wavelength thereof, more antennas may be generally used, so that communication may be performed based on beams to compensate for 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, the current research tends to mix beam forming, i.e. the rf beam and the digital beam together form the final beam.
In the research of New Radio Access Technology (NR), 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 base station, a terminal may also configure a large number of antennas to form uplink transmission beams, and a base station side may also select a suitable reception beam to match and receive an uplink signal. In the existing research, because the energy difference of different beams is large, the interference caused by different transmission beams of the UE to the adjacent area is also greatly different, so different transmission beams of the UE should have different power parameter configurations, and the power parameter settings of different transmission beams should take the interference level caused to the adjacent area into account.
In view of the above problems in the related art, no effective solution has been proposed so far.
