  • the present invention relates to a wireless communication technology, and in particular, to a method, a detection method, a base station, a terminal, and a computer storage medium for transmitting control information.
  • the link reliability of the physical layer is a very important issue.
  • a deterioration in physical link quality can cause different levels of system performance degradation.
  • the data channel at this level of the link must guarantee a transmission success rate of about 90% at the physical layer.
  • CQI Channel Quality Indication
  • the target error is about 0.9.
  • the block rate is used to select the appropriate modulation and coding scheme. If the data block does not pass the actual transmission, the terminal needs to feed back the NACK to the base station, and the base station retransmits according to the feedback of the terminal, and may initiate multiple retransmissions for the untransmitted data block to improve the solution of the final data block. Success rate.
  • the link reliability requirements are very high, and the physical control information generally has no retransmission mechanism.
  • the one-time transmission accuracy rate of the physical control information generally needs to reach 99%, and a part of the more important control information transmission success rate reaches 99.9%. Even higher, some system performance caused by loss of control information is severely degraded, such as the physical control format indicator channel (PCFICH) carrying the indication information of the physical control channel symbol).
  • PCFICH physical control format indicator channel
  • data channels can generally use multi-antenna closed-loop beamforming technology, which can achieve high Transmission throughput, but a feature of the beamforming technique is that the energy is very concentrated in space, although the performance is very good when accurate, but the performance is degraded once the beam direction is inaccurate, especially in large-scale antenna systems.
  • the beam is very narrow. Although the energy is very concentrated, the gain is very high when the beam is aligned. If the beam is slightly deviated, the performance will be seriously degraded, and even the signal may not be received completely.
  • the data channel is characterized by emphasis on transmission efficiency and poor robustness.
  • the data channel has a control channel to perform some dynamic indication of the data channel transmission strategy, when this situation is found, the beam can be quickly adjusted to a wide beam or beam switching, so that it does not cause particularly serious impact, and the data channel itself
  • the target block error rate requirement is not very demanding and can be retransmitted, so there are no serious problems.
  • the physical control channel in the low-frequency LTE system, the physical control channel generally adopts a relatively robust transmission mechanism, and does not rely on channel state information (CSI) feedback, such as LTE physical downlink control channel (PDCCH, Physical Downlink).
  • CSI channel state information
  • Control Channel adopts the diversity technology SFBC transmission mode or the SFBC+FSTD diversity transmission mechanism, which has high robustness and low-order modulation coding, which further ensures high robustness. Therefore, the low-frequency system can work well, and there is no frequent communication failure link suddenly broken, and the problem of control information and data information cannot be solved at all.
  • the data channel greatly enhances its coverage due to the use of Beamforming.
  • the control channel if the robustness is guaranteed to be transmitted by a wide beam or diversity technique (such as SFBC), Therefore, there is a clear problem of coverage asymmetry.
  • a very low code rate may be required for control channel transmission, which means lower control information transmission efficiency.
  • the control channel also considers beamforming transmission using a certain width of the beam using channel state information, which means that the control channel also needs to support closed-loop multiple-input multiple-output. (MIMO) transmission technology;
  • control channel supports MIMO transmission, the resource utilization efficiency and enhanced coverage will be significantly improved, but the robustness of the link will be difficult to guarantee.
  • the control channel is generally robust. The data transmission can be restored by making some adjustments to the data transmission through the control channel. But if the control also uses MIMO transmission, Once the beam pair is out of order, such as when the terminal is moving and because the line-of-sight direct (LOS) path physically blocks (Blocking) the current transmission beam, it will cause an overall chain scission, causing severe system performance degradation.
  • LOS line-of-sight direct
  • the uplink channel status information cannot be correctly fed back, the downlink control and data will not be accurate, and the uplink control channel will be lost. In this case, the uplink and downlink, data and control links will be broken. It is not possible to quickly perform link recovery and reconstruction.
  • the case where the beam cannot be aligned or blocked can be as shown in FIG.
  • the prior art considers MIMO technology for both control and data, so there is always the problem described above; once the beam cannot be aligned or blocked, downlink control, downlink data, The uplink control and the uplink data are all broken. If there is downlink data to be sent at this time, the terminal does not receive the control information, and the data is not received, and no feedback is given. The terminal may understand that there is no information to be sent. It has been lost from the network, but the terminal may not even be aware of the loss of the link. It is wrong to assume that there is no data transmission on the downlink.

技术领域
本发明涉及无线通信技术，具体涉及一种控制信息的发送方法、检测方法、基站、终端和计算机存储介质。
背景技术
无线通信系统中，物理层的链路可靠性是一个非常重要的问题。物理链路质量变坏会引起不同程度的系统性能的下降。一般来说，数据信道这一层级的链路在物理层要保障90％左右的传输成功率，比如计算并上报信道质量指示(CQI，Channel Quality Indication)时，都是按照这0.9左右的目标误块率来选择合适的调制编码方式。如果实际传输时数据块没有传对，终端需要反馈NACK给基站，基站根据终端的反馈进行重传，可以发起多次针对未传对的数据块进行重传，提高最终的数据块的解对的成功率。除了物理层的重传技术，还可以在高层发起更大数据块的进行重传。对于控制信道，链路可靠性要求很高，物理控制信息一般没有重传机制，物理控制信息一次性传输正确率一般要要达到99％，有一部分更重要的控制信息传输成功率要达到99.9％甚至更高，避免控制信息丢失引起的一些系统性能严重下降，比如物理控制格式指示信道(PCFICH，Physical Control Format Indicator CHannel)承载物理控制信道符号的指示信息)。
在低频的系统中，比如4G长期演进(LTE，Long Term Evolution)系统，数据信道一般可以使用多天线的闭环波束赋型技术，可以获得很高的 传输吞吐量，但是波束赋型技术的一个特点是，能量在空间上非常集中，虽然准确时性能非常好，但一旦波束方向有一些不准确就会性能下降，尤其是大规模天线系统中形成的波束很窄，虽然能量非常集中波束对准时增益很高，波束稍有偏离就会性能严重下降，甚至可能完全收不到信号，数据信道的特点是重视传输效率而鲁棒性会差一些，不过由于数据信道之前有控制信道进行一些动态的指示数据信道传输策略的调整，当发现这种情况时可以快速的调整到宽波束或者进行波束切换，因此不会造成特别严重影响，而且数据信道本身的目标误块率要求就不是非常的苛刻，还可以重传，因此不会存在很严重的问题。
对于控制信道，低频的LTE系统中，物理控制信道一般采用比较鲁棒的传输机制，不依赖于信道状态信息(CSI，Channel State Information)的反馈，比如LTE的物理下行控制信道(PDCCH，Physical Downlink Control Channel)采用分集技术SFBC的传输方式或者SFBC+FSTD的分集传输机制，鲁棒性高，并且采用低阶调制编码，进一步的保障了高鲁棒性。因此低频系统中可以很好的进行工作，不会经常出现通信突然链接断掉，完全无法解出控制信息及数据信息的问题。
但随着天线数目越来越多，数据信道由于使用了Beamforming会大大的增强其覆盖，但对于控制信道，如果保障鲁棒性属于用很宽的波束或分集技术(例如SFBC)来进行传输，因此有明显的覆盖不对称问题。为了解决该问题可能需要非常低的码率来进行控制信道传输，这意味着较低的控制信息传输效率，对于高频系统，这个问题会非常的明显，因为高频的覆盖本来就是一个很大的问题需要利用大规模天线的Beamforming增益来对抗较大的路损，因此控制信道也会考虑利用信道状态信息采用一定宽度的波束进行beamforming传输，这意味着控制信道也需要支持闭环多输入多输出(MIMO)传输技术；
如果控制信道支持MIMO传输，会明显地提高资源利用效率和增强覆盖，但链路的鲁棒性会比较难以保障，低频的LTE系统中，如果数据链路出现问题，控制信道一般还是比较鲁棒的，可以通过控制信道进行对数据传输进行一些调整，恢复数据链路。但是如果控制也使用了MIMO传输， 一旦波束对不准时，比如终端移动的情况以及由于视距直射(LOS)径物理阻塞(Blocking)掉了当前传输波束，会造成整体断链，引起严重的系统性能下降。比如波束不能对准，那么上行信道状态信息也无法正确的反馈，下行控制和数据也不会准确，继而上行控制信道也会丢失；这种情况下上行和下行，数据和控制链路都会断掉，不能快速的进行链路恢复重建。波束不能对准或阻塞的情况可如图1所示。
在高频系统中，大规模天线应用时，现有技术对于控制和数据都会考虑采用MIMO技术，因此总是存在上面描述的问题；一旦波束不能对准或阻塞，会出现下行控制、下行数据、上行控制、上行数据全部断链，如果此时有下行数据要发，终端收不到控制信息，更收不到数据，也不会进行任何反馈，可能导致终端理解为没有信息发送，此时终端已经从网络中丢失了，但终端甚至不可能意识到链路的丢失这个问题，会错误的认为是下行没有数据发送。
