Description

Method and device for processing uplink signal transmission power, base station and terminal

Technical Field

The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for processing uplink signal transmission power, a base station, and a terminal.

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 base station (eNB, e-Node-B) may configure a terminal (UE) through downlink control information, or the terminal receives configuration of a higher layer (high layers), which is also called to configure 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 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:

power spectral density of UE transmission (i.e. power per RB) = 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 measures the downlink reference signal RSRP and subtracts the known RS signal power, so that the path loss estimation is carried out.

For the PUSCH and SRS, the eNodeB determines the weight of the path loss in the uplink power control of the UE by the parameter α. 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 consists of two parts, MCS-based power adjustment Δ TF 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. Closed loop power control refers to the UE adjusting the transmit power of the UE through TPC commands 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 transition between these two different adjustment modes is semi-static, and the eNB indicates, through dedicated RRC signaling, whether the UE employs an accumulation mode or an absolute value mode.

The accumulation mode refers to that the current power adjustment value is the adjustment step size indicated in one TPC increased/decreased on 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, the format of DCI 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 manner 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 and can provide 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, since each antenna needs to have a radio frequency link, the problem of increasing cost and power consumption is also caused based on digital beam forming. Therefore, the current research tends to mix beam forming, i.e. the rf beam and the digital beam together form the final beam.

In a New Radio Access Technology (New Radio Access Technology) study, a high frequency communication system may also be configured with a large number of antennas to form uplink transmission beams in addition to a base station to configure a large number of antennas to form downlink transmission beams to compensate for spatial fading of high frequency communication, and a base station side may also select a suitable reception beam to match with a received uplink signal. How to control the power of the uplink transmission signal to adapt to the beam-based transmission mode in the high-frequency communication is a problem to be solved.

In view of the above technical problems in the related art, no effective solution has been proposed at present.

And calculating the open-loop industrial control point of each transmitting beam according to the open-loop industrial control point = target power + open-loop path loss compensation path loss, and determining the uplink signal transmitting power of each transmitting beam according to the uplink signal transmitting power = open-loop industrial control point + power offset.

It should be noted that, the calculation methods of the open-loop industrial control point and the uplink signal transmission power are combined together, and are not described herein again.

In the case that the parameter includes a combination of three, the step S304 may be represented as: determining the power offset of the transmission mode according to the uplink transmission power adjustment value and the power adjustment enabling bit of the transmission mode; the power adjustment enabling bit effectively indicates that the sending mode needs to adjust the sending power of the uplink signal, and the power offset of the sending mode is an uplink sending power adjustment value; determining an open-loop industrial control point of a transmission mode corresponding to the power adjustment enabling bit according to the path loss PL and the target power; and determining the uplink signal transmission power of the transmission mode according to the power offset and the open-loop industrial control point.

It should be noted that, the calculation methods of the open-loop industrial control point and the uplink signal transmission power are combined together, and are not described herein again.

In addition, in the case that the parameter includes a combination of four, the step S304 may be represented as: determining the power offset of the transmission mode according to the uplink transmission power adjustment value and the bitmap of the transmission mode; wherein, the bit value of the bitmap being 1 indicates that the transmission mode corresponding to the bit value being 1 needs to adjust the uplink signal transmission power, and the power offset of the transmission mode corresponding to the bit value being 1 is an uplink transmission power adjustment value; determining an open-loop industrial control point of a transmission mode corresponding to the bit value of 1 according to the path loss PL and the target power; and determining the uplink signal transmission power of the transmission mode corresponding to the bit value of 1 according to the power offset and the open-loop industrial control point.

It should be noted that, the calculation methods of the open-loop industrial control point and the uplink signal transmission power are combined into a whole, and are not described herein again.

For example, the terminal uses one transmission beam to transmit the uplink signal, the base station uses two reception beams to receive the uplink signal in a time division manner, and the base station configures 2 path losses for the terminal, where each reception mode corresponds to one path loss, so that each reception mode corresponds to one uplink signal transmission power, and when the base station uses the first reception beam to receive the uplink signal, the terminal uses the uplink signal transmission power corresponding to the first reception beam to transmit the uplink signal.

In one embodiment of the present invention, when the transmission mode is a transmission frequency band or a frequency domain position, different transmission frequency bands or frequency domain positions have different path loss and different target powers. For example, in high frequency communication, the uplink transmission bandwidth is 80MHz, and may be divided into 4 frequency bands of 20MHz, and then the 4 frequency bands may have different path loss and target power.
