Description

A kind of transmission method of interferometry reference signal and equipment
Technical field
The present invention relates to the communications field, particularly relate to a kind of transmission method and equipment of interferometry reference signal.
Background technology
The network equipment, by sending dispatch to subscriber equipment (User Equipment, UE), sends upstream data. signals or downlink data receiving signal to indicate UE according to this dispatch.As everyone knows, dispatch is determined by the network equipment, the network equipment is in order to make rational scheduling, need to measure the state of channel in advance, concrete, such as, when UE needs to send upstream data. signals to the network equipment, first UE sends detection reference signal (Sounding Reference Signal to the network equipment, SRS), the network equipment is measured to obtain uplink channel status information (Channel State Information to the SRS received, CSI), and then determine dispatch according to the up CSI obtained, and the dispatch determined is sent to UE, such UE just can send upstream data. signals according to this dispatch to the network equipment.But in systems in practice, due to the fluctuation of interference, the network equipment measures the CSI when CSI obtained can not reflect that upstream data. signals is transmitted completely really to SRS, and the dispatch that therefore network equipment is determined may be irrational.
In order to alleviate the inaccurate problem of dispatch brought due to disturbance fluctuation, prior art provides a solution, after UE receives the dispatch of network equipment transmission, transmitter first can send reference signal (Reference Signal according to this dispatch to receiver, RS), so that receiver is measured RS, then transmitter or receiver determine corresponding Adjusted Option according to measurement result, carry out the transmission of data-signal according to dispatch and Adjusted Option between final receiver and transmitter, when wherein transmitter is the network equipment, receiver is UE, when transmitter is UE, receiver is the network equipment.
Inventor finds such scheme, and at least there are the following problems, at time division duplex (TimeDivision Duplex, TDD) in system, such as, when transmitter is UE, when receiver is the network equipment, after UE receives the dispatch of network equipment transmission, UE needs to send RS according to dispatch and ascending-descending subframes configuration information to the network equipment, when after network equipment determination Adjusted Option, UE is again according to dispatch and/or Adjusted Option, and ascending-descending subframes is configured in the transmission identical frequency band carrying out data-signal.As everyone knows, ascending-descending subframes configuration information is that the network equipment is determined according to the up-downgoing business of the community of self institute overlay area, because the service conditions of different districts is different, therefore probably the ascending-descending subframes configuration of neighbor cell is different, that is for the uplink of certain community, the interference that the upward signal that the UE that there is its adjacent community sometimes sends causes, the interference that the downstream signal that there is network equipment transmission corresponding to its adjacent community sometimes causes, may cause like this: UE and the network equipment transmit the interference that RS can be subject to upward signal, and itself and network equipment transmission of data signals can be subject to the interference of downstream signal, namely measure the interference that the interfere information that obtains of RS and transmission of data signals be subject to there are differences, that is the Adjusted Option made or not accurate enough, so still cannot solve the problem of disturbance fluctuation.
