Description

A kind of Poewr control method of detection reference signal, system and device

Technical field

The present invention relates to the communications field, relate in particular to a kind of Poewr control method, system and device of detection reference signal.

Background technology

Long Term Evolution (the LTE-A of evolution, Long Term Evolution-Advanced) provisional capital up and down of system is with OFDM (OFDM, Orthogonal Frequency Division Multiplexing) be the frequency division systems of basic multiple access multiplexing mode, with traditional with code division multiple access (CDMA, Code Division Multiple Access) be that the wireless communication system of basic multiple access multiplexing mode is different, the LTE-A system does not have processing gain, the residential quarter is inner because complete frequency division quadrature, so almost there is no interference problem, but the processing in the interference problem of cell edge is relatively thorny.Multipoint cooperative (CoMP, Coordinated Multiple Point) technology is to utilize the transmitting antenna cooperation transmission of a plurality of residential quarters, realize better quality and the transmitting of cell edge place Radio Link, can effectively solve the interference problem of cell edge.

Passed through on 3GPP RANI#63b the research scene of CoMP technology is divided into four kinds: scene one is homogenous networks, covers three residential quarters under an eNB, and each residential quarter has different cell ID (cell ID), and each cell base station has identical transmitting power; Scene youngster is homogenous networks, covers a plurality of residential quarters by optical fiber under an eNB, and each residential quarter has different cell ID, and each cell base station has identical transmitting power; Scene three is heterogeneous networks, cover a plurality of residential quarters by optical fiber under an eNB, each residential quarter has different cell ID, macrocell and far end radio frequency node (RRH, Remote Radio Head) have different transmitting powers, the transmitting power of macrocell is much larger than RRH usually; Scene four is heterogeneous networks, covers a plurality of residential quarters by optical fiber under an eNB, and each residential quarter has identical cell ID, and macrocell and RRH have different transmitting powers, and the macrocell transmitting power is much larger than RRH usually.

The CoMP technology is divided into descending CoMP and up CoMP, and wherein, descending CoMP refers to that a plurality of nodes unite for the user sends data/reference signal, and up CoMP refers to that a plurality of nodes receive data/reference signal that users send.

In 3GPP TR36.819, the CoMP technology is divided into explicit feedback, implicit feedback, SRS feedback totally three kinds of feedback systems, wherein, explicit feedback is that receiving terminal directly feeds back to transmitting terminal with viewed channel; Implicit feedback is that receiving terminal feeds back to transmitting terminal after treatment to viewed channel, for example, with observed channel condition information (CQI to channel, Channel Quality Information)/pre-coding matrix information (PMI, Precoding Matrix Indication)/order information (RI, Rank Indication) feeds back to transmitting terminal; SRS is fed back in time division duplex (TDD, Time Division Duplexing) system, based on the channel reciprocity characteristics, obtains descending channel information after estimating according to the SRS signaling channel that receives.Wherein, as a kind of important feedback system of CoMP system, the SRS feedback can obtain more accurate channel condition information by less feedback overhead.

In sum, in LTE/LTE-A, the function of SRS feedback generally has two kinds: a kind of is to utilize the SRS feedback to obtain uplink channel information, carries out uplink scheduling, resource distribution, transfer of data; A kind of is to utilize SRS feedback to obtain descending channel information (TDD system in), carries out that descending scheduling, resource distribute, transfer of data.

In prior art, uplink power control can be regarded as by open Loop Power control and close-loop power control two parts and consists of, wherein the calculating of the path loss in open Loop Power control is to have supposed that descending path loss equals up path loss, thereby estimates that according to downlink reference signal descending path loss obtains up circuit loss value.But, in CoMP scene three and scene four, because there is the transmitting power disequilibrium in the minizone, according to maximum receiving gain principle, user's descending CoMP transmitting node set and the set of up CoMP receiving node are not identical, so its descending path loss and be not equal to up path loss, so path loss calculates and is inaccurate, thereby cause open Loop Power control to have relatively large deviation, to such an extent as to still can not in time obtain good power control effect by the fine setting effect of closed loop.Excessive path loss calculates, and not only waste is caused in user's transmitting power, and can cause larger interference to other user; Otherwise too small path loss calculates, and possibly can't reach coverage and the quality of reception requirement of customer requirements.
