Description

Power control method, system and device for detecting reference signal

The present invention relates to the field of communications, and in particular, to a power control method, system, and apparatus for detecting a reference signal. Background technique

The uplink and downlink of the Long Term Evolution-Advanced (LTE-A) system are both frequency division systems based on OFDM (Orthogonal Frequency Division Multiplexing) and multiple access multiplexing methods. The CDMA-A system has no processing gain, and the LTE-A system has no processing gain. The internal frequency division is orthogonal, so there is almost no interference problem. However, the handling of interference problems at the edge of the cell is relatively tricky. The Coordinated Multiple Point (CoMP) technology utilizes the transmit antennas of multiple cells to perform coordinated transmission to achieve higher quality and reliable transmission of the radio link at the cell edge, which can effectively solve the interference problem at the cell edge.

On 3GPP RAN1 #63b, the research scenarios of CoMP technology are divided into four types: scenario 1 is a homogeneous network, and an evolved base station (eNB) covers three cells, each cell having a different cell identifier (cell ID). Each cell base station has the same transmit power; scenario 2 is a homogeneous network, and one eNB covers multiple cells through an optical fiber, each cell has a different cell ID, and each cell base station has the same transmit power; scenario 3 is a heterogeneous network. An eNB covers multiple cells through an optical fiber, and each cell has a different cell ID. The macro cell and the remote radio head (RRH) have different transmit powers. Generally, the transmit power of the macro cell is much larger than the RRH. It is a heterogeneous network. One eNB covers multiple cells through an optical fiber. Each cell has the same cell ID. The macro cell and the RRH have different transmit powers. Generally, the macro cell transmit power is much larger than the RRH. Its The RAN is a random access network.

The CoMP technology is divided into downlink CoMP and uplink CoMP. The downlink CoMP refers to multiple nodes jointly sending data/reference signals to users. The uplink CoMP refers to multiple nodes receiving data/reference signals sent by users.

In 3GPP TR36.819, CoMP technology is divided into three feedback modes: explicit feedback, implicit feedback, and sounding reference signal (SRS) feedback. The explicit feedback is that the receiving end directly feeds back the observed channel to the transmitting end; the implicit feedback is that the receiving end processes the observed channel and then feeds back to the transmitting end, for example, the channel state of the observed channel. Information (CQI, Channel Quality Information) / Precoding Matrix Indication (PMI, Precoding Matrix Indication) / Rank Information (RI, Rank Indication) is fed back to the transmitting end; SRS feedback is in Time Division Duplexing (TDD) system According to the channel reciprocity feature, the downlink channel information is obtained according to the received SRS signal channel estimation. Among them, as an important feedback method of the CoMP system, the SRS feedback can obtain more accurate channel state information through a smaller feedback overhead.

In summary, there are two types of SRS feedback functions in LTE/LTE-A: one is to use SRS feedback to obtain uplink channel information, perform uplink scheduling, resource allocation, and data transmission; one is to use SRS feedback to obtain downlink channel. Information (in the TDD system), performing downlink scheduling, resource allocation, and data transmission.

In the prior art, the uplink power control can be regarded as composed of two parts: open loop power control and closed loop power control. The path loss calculation in the open loop power control assumes that the downlink path loss is equal to the uplink path loss, according to the downlink reference signal. The downlink path loss is estimated to obtain the uplink path loss value. However, in CoMP scenario 3 and scenario 4, due to the unbalanced transmit power between cells, according to the principle of maximum receive gain, the downlink CoMP transmitting node set and the uplink CoMP receiving node set of the user are not the same, and the downlink path loss is It is not equal to the uplink path loss, so the path loss calculation is not accurate, which leads to a large deviation of the open-loop power control, so that the fine-tuning effect through the closed loop still cannot Get good power control results in time. Excessive path loss calculation not only wastes the user's transmit power, but also causes large interference to other users. Conversely, if the path loss is too small, the user's required coverage and reception quality requirements cannot be met. Summary of the invention
