Background technology
Space Frequency Block Coding (Spatial frequency block coding, SFBC) is a kind of transmission side of transmitting diversity Method, this method utilizes two ports, in conjunction with alamouti coding mode transmission datas.Since the channel variation of two ports is mutual It is independent, therefore SFBC can obtain two diversity order gains, have stronger robustness to channel fading.
Information is sent using beamforming technique in the third generation mobile communication system (such as 5G), specifically, including profit With mutiple antennas and two precoding vectors, two ports are virtually turned to, two ports correspond to two wave beams.The number of antenna is got over More, the space angle range of beam energy covering is with regard to smaller, i.e., wave beam is narrower, and beam energy is more concentrated.Then in wave cover Within the scope of space angle, the reception energy of user equipment is higher, is more conducive to the promotion of data transmission performance.By wave beam forming with SFBC transmission modes combine, and SFBC is evolved into the SFBC of wave beam forming：Base station is using two ports of virtualization as SFBC Two ports when transmission, utilize SFBC transmission mode transmission datas.Since 5G systems will be communicated in higher frequency range, in order to The more serious decline of high frequency band signal is resisted, 5G systems will use more antennas to carry out wave beam forming, and therefore, wave beam may become It obtains narrower.
For example, when base station and user equipment (user equipment, UE) are when high band communicates, configure in base station side Antenna amount on two virtualization ports greatly increases, and then causes the corresponding wave beam in two ports very narrow, therefore, wave beam It is easy to be blocked.If the wave beam of one of port is blocked, the channel energy of the port will be greatly lowered, and lead The signal-to-noise ratio of Data Detection is caused to decline to a great extent, to be easy to cause data transmission fails.In existed system, user equipment is for number According to testing result feedback acknowledgement/non-acknowledgement (ACK/NACK), whether this data of signals base correctly transmit.The machine System base station will be caused to be continuing with the port transmission data being blocked, so as to cause data re-transmission and/or new data transmission all It is possible that can not correctly transmit, subsequent data transmission performance is influenced.

The embodiment of the present application provides a kind of method for sending information, for making terminal device detect network side equipment in real time Whether the ports SFBC are blocked, and report the relevant information of feedback, to improve the transmission performance of data.
As described in Figure 1, which sends forwarding method and includes the following steps:
Step 101:Terminal device receives data and reference signal from network side equipment.
The reference signal includes the first reference signal, and first reference signal is sent including at least two first ports The first demodulated reference signal, first demodulated reference signal be the data demodulated reference signal, the terminal device The data are received according to the first transmission plan；Described first adjusts reference signal for DMRS (Demodulation reference signal)。
Step 102：Terminal device sends the first information to the network side equipment.
The first information includes the testing result of the data and/or at least one channel state information (Channel StateI nformation, CSI), each CSI is according to the measurement determination to the reference signal, each in the CSI One in information and channel quality indicator (CQI), the port selection information is selected to be used to indicate the net including at least port At least one second port of network side apparatus, the CQI can select information to calculate according to the port.
Further, further include in the CSI：Indicate at least one of information, port quality information and PMI information, Wherein, instruction information is used to indicate the second transmission plan that the network side equipment is used when transmitting the second data, the end At least one second port second transmission plan that mouth selects information to select transmits second data and uses Port；The port quality information is used to indicate the quality of at least two first port；The PMI information is used to indicate institute State the pre-coding matrix that network side equipment uses in second transmission plan.
First transmission plan includes Space Frequency Block Coding SFBC transmission plans, and second transmission plan includes that SFBC is passed At least one of transmission scheme and closed loop beam figuration transmission plan.Specifically, the second transmission plan uses SFBC transmission plans, Or closed loop beam figuration transmission plan can be true to the measurement result of the reception power of the reference signal according to terminal device It is fixed.
Under SFBC transmission modes, in addition to carrying out Data Detection, also to measure the first demodulated reference signal DMRS and obtain end The energy information of mouth, judges whether there is port according to energy information and is blocked, and recommends the transmission plan transmitted next time (at least Including SFBC and closed loop beam figuration) and/or port selection, and/or corresponding precoding instruction (Precoding matrix Indicator, PMI) and channel quality instruction (Channel quality indicator, CQI), or report multiple alternative The port selection information and/or PMI and/or CQI of transmission plan, so that network side equipment carries out decision.
Terminal device, can also be to network side other than can recommend the transmission plan transmitted to network side equipment next time Equipment reports the port of multiple alternate transmission schemes to select information and/or PMI and/or CQI, so that network side equipment is determined Plan.
A kind of terminal device reports the mode of the first information to include：
Terminal device receives the data and the first demodulated reference signal DMRS that network side equipment is sent.Wherein, described first Demodulated reference signal can be sent by two first ports of network side equipment, such as port a and port b.First DMRS is used In estimation two first ports of SFBC, (port a and port b) arrive the down channel of terminal device (such as UE), to which UE can be solved Adjust the data on the two ports.
The selection of the first port a and b can be network side equipment according to the CSI feedback before UE (such as based on this The CSI feedback for the CSI-RS that secondary transmission data and DMRS are sent before) determine.For example, what base station UE before was reported PMI confirms and uses precoding vector va,vb, port a and port b is formed, and using port a and port b as this SFBC's Two ports.In subcarrier f1,f2On, the down channel coefficient for enabling port a and port b to the UE is respectively ha,hb, then institute State down channel coefficient ha,hbBase station to the UE down channel matrix H respectively with two port precoding vector va,vb Product.It is s to enable data symbol to be sent on described two subcarriers1,s2, then the UE is in subcarrier f1,f2On connect Receiving data symbol is
Wherein, n1,n2Indicate the receiver of the UE in subcarrier f1,f2On reception noise.
Optionally, the reference signal further includes the second reference signal, then the terminal device is referred to according to described first The measurement result of signal determines the first information, specifically includes：The terminal device is according to first reference signal and institute The reception power for stating the second reference signal determines at least one of first information CSI, and obtains at least one second The channel coefficients of port.
Wherein, second reference signal includes in measuring reference signals CSI-RS and the second demodulated reference signal DMRS It is at least one, wherein second reference signal is sent by least one third port of the network side equipment.
Specifically, terminal device determines at least one according to the reception power of the first reference signal and the second reference signal The process of CSI is：UE measures the first DMRS of two first ports, obtains the channel estimation value of two first portsUE According to the channel energy of 2 first portsUE judges whether there is first port and is blocked.For example, the channel of port a Energy declines 20dB or so compared to a upper subframe, or is less than some threshold value, then UE can consider that the channel of port a is hidden Gear.Alternatively, UE measures the reception power P of the first DMRS of two first ports1And P2, by judging P1And P2Whether one is less than A threshold value, or whether decline 20dB compared with the reception power of a upper subframe, to determine whether there is first port to be blocked.Root According to the detection quality information of two first ports, UE generates CSI, the CSI include port quality information, port selection information, Recommend at least one of the second transmission plan, the PMI used and corresponding CQI.Wherein, the second transmission plan is that UE recommends Next data transmission use transmission plan, the quality of port quality information signals base port a and port b, for example whether by It blocks.Port selects information to be used for signals base second port label, is used for the data transmission of the second transmission plan.PMI is indicated Pre-coding matrix be used for the second transmission plan pre-coding matrix.
Optionally, UE can be in reporting port quality, the transmission plan of recommendation, port selection, PMI and corresponding CQI A part.Optionally, UE can carry out CSI feedback according to following table.
Table 1
In table 1, Y indicates that port is not blocked, and N indicates that port is blocked.
For UE according to the reception power of the port a and port b of detection, the rule for generating the CSI of feedback is as follows：
If the reception power of all first demodulated reference signals is all higher than equal to predetermined power, the instruction letter Second transmission plan for ceasing instruction is identical as the first transmission plan；If the reception power of first demodulated reference signal In at least one be less than the predetermined power, then it is described instruction information instruction second transmission plan and the first transmission side Case is different.
If the reception power of the first reference signal of all first demodulation is all higher than equal to predetermined power, the end The mouth selection selected second port of information includes the first port；If first first reference signal of demodulation connects It receives at least one in power and is less than the predetermined power, then at least one first port difference is not included in the port Select the selected second port of information.
Optionally, in table 1, the selection of port c, port d can be obtained according to the measurement of the second reference signal.PMIc It is pre-coding matrix instructions of the UE for closed loop beam figuration transmission plan and port c, is used to indicate base station using closed loop The precoding vector used when beamforming transmission data can also be to be obtained according to the measurement of the second reference signal.Due to end The reception energy of mouthful b is too low, and UE needs base station is recommended to change to that new port c carries out subsequent transmission and/or pre-coding matrix refers to Show PMI, is used to indicate the pre-coding matrix of base station subsequent data transmission.Similarly, the meaning of PMId is similar.Optionally, in table 1 " UE feed back CSI " can only include the part of above-mentioned parameter, such as comprising the second transmission plan, port selects and CQI, or Person includes other situations such as the second transmission plan, PMI and CQI.
In addition, terminal device can recommend base station to be continuing with the first transmission plan according to the reception power of reference signal, Such as shown in table 2.
Table 2
Difference lies in if some port is blocked in network side, UE can recommend to continue to use table 2 with table 1 The transmission plan of SFBC, but CSI includes recommending new port.On the one hand, if SFBC two ports (such as port a and Port b) uses different precoding vectors, and the corresponding beam direction in two ports is different, then two wave beams are blocked simultaneously Probability can reduce, and the robustness that anti-wave beam blocks is stronger；On the other hand, since closed loop beam figuration scheme has higher closed loop The detection signal-to-noise ratio of beam forming gain, data is higher, in the case where wave beam is not blocked, has better Data Detection Energy.
Further, can be determined by UE using the content of table 2 or table 1 in the CSI that UE is reported.For example, root Reference signal before being sent according to this data and DMRS measures, and UE is learnt in addition to port a and b, if also has other ports can It is preferable to complete data transmission.For example, port b is blocked, and if port c) is other than port a and port b, the end of suboptimum Mouthful, but still SFBC data transmissions (for example, the signal-to-noise ratio of Data Detection is more than a thresholding) can be preferably served, then UE It can recommend to be continuing with SFBC, but it is a and c to update port；Alternatively, UE directly recommends the precoding instruction transmitted next time PMIac.If UE judges other than port a and port b, directly to determine to use without other satisfactory ports or UE Closed loop beam figuration scheme, then UE can recommend base station to be switched to the transmission plan of closed loop beam figuration, and recommend end at this time Mouth is c, or it is PMIc directly to recommend PMI.
Optionally, UE can also be calculated according to Tables 1 and 2 simultaneously, respectively obtain closed loop beam figuration in table 1 The CQI=CQI_2 of SFBC in CQI=CQI_1 and table 2, UE can select corresponding transmission plans of larger CQI and corresponding PMI is reported.Optionally, the CSI progress subsequent data transmissions of table 2 had both may be used in the network side equipment of receiving terminal, The content transmission of table 1 may be used, or do not use table 1 and table 2 to carry out formality data biography according to other network informations It is defeated, specifically use which kind of transmission plan that can be decided in its sole discretion by network side equipment.
Optionally, the case where needing to report CSI for each, UE are also based on SFBC and closed loop beam figuration, on Two sets of CSI are reported, determine which transmission plan used by base station.
