本公开要求在2018年03月05日提交中国专利局、申请号为201810180673.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本公开中。The present disclosure claims priority to Chinese Patent Application No. 20110018 067 3.8, filed on March 5, 2010, the entire disclosure of which is hereby incorporated by reference.
技术领域Technical field
本公开涉及通信技术领域，例如涉及一种信息传输的方法、装置和通信节点。The present disclosure relates to the field of communication technologies, for example, to a method, apparatus, and communication node for information transmission.
背景技术Background technique
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于高频信号波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。With the development of communication technology, the demand for data services continues to increase, and the available low-frequency carriers are already very scarce. Therefore, high-frequency (30-300 GHz) carrier communication based on underutilization has become an important communication for solving high-speed data communication in the future. One of the means. High-frequency carrier communication has a large available bandwidth and can provide efficient high-speed data communication. However, a big technical challenge faced by high-frequency carrier communication is relatively low-frequency signals. The fading of high-frequency signals in space is very large, although it causes spatial fading loss in high-frequency signals in outdoor communication, but due to high The reduction in the wavelength of the frequency signal typically allows more antennas to be used so that communication can be based on the beam to compensate for fading losses in space.
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。However, when the number of antennas increases, since each antenna needs to have a set of RF links at this time, digital beamforming also brings about an increase in cost and power loss. Therefore, the study tends to mix beamforming, that is, the RF beam and the digital beam together form the final beam.
在新的无线接入技术(New Radio Access Technology，NR)中，高频通信系统除了第一通信节点会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落，第二通信节点同样也会配置大量的天线形成上行传输波束，此时测量参考信号(Sounding Reference Signal，SRS)的发送也将会采用波束的形式发送。对于上行信号的天线切换发送，相关技术中还没有对应的实现方案。In the new Radio Access Technology (NR), the high-frequency communication system configures a large number of antennas to form a downlink transmission beam to compensate for the spatial fading of high-frequency communication, and the second communication node also A large number of antennas are configured to form an uplink transmission beam. The transmission of the Sounding Reference Signal (SRS) will also be transmitted in the form of a beam. For the antenna switching transmission of the uplink signal, there is no corresponding implementation solution in the related art.

具体实施方式Detailed ways
下文中将结合附图对本公开的实施例进行说明。Embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings.
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions.
在长期演进(Long Term Evolution，LTE)中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)用于承载DCI，其中，DCI可包括上、下行调度信息，以及上行功率控制信息。DCI格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE的演进(Long Term Evolution-Advanced，LTE-A)版本(Release)12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。第一通信节点，例如演进型基站(e-Node-B，eNB)可以通过下行控制信息配置第二通信节点设备，例如用户设备(User Equipment，UE)，或者第二通信节点设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE。In the Long Term Evolution (LTE), a Physical Downlink Control Channel (PDCCH) is used to carry DCI, where the DCI may include uplink and downlink scheduling information, and uplink power control information. The DCI format is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to the LTE Evolution (Long Term Evolution-Advanced, LTE-A) version (Release). ) 12 (LTE-A version 12) has added DCI format 2B, 2C, 2D to support a variety of different applications and transmission modes. The first communication node, such as an evolved base station (e-Node-B, eNB), may configure a second communication node device, such as a User Equipment (UE), by using downlink control information, or the second communication node device accepts a higher layer (higher) The configuration of the layers, also known as configuring the UE through higher layer signaling.
测量参考信号(Sounding Reference Signal，SRS)是一种第二通信节点设备与第一通信节点间用来测量无线信道信息(Channel State Information，CSI)的信号。在长期演进系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。The Sounding Reference Signal (SRS) is a signal used by the second communication node device and the first communication node to measure Channel State Information (CSI). In the LTE system, the UE periodically transmits the uplink SRS on the last data symbol of the transmission subframe according to parameters such as the frequency band indicated by the eNB, the frequency domain location, the sequence cyclic shift, the period, and the subframe offset. The eNB determines the uplink CSI of the UE according to the received SRS, and performs operations such as frequency domain selection scheduling, closed loop power control, and the like according to the obtained CSI.
在LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即：天线专有的SRS，而对PUSCH的用于解调的参考信号(De Modulation Reference Signal，DMRS)则进行预编码。第一通信节点通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点估计出上行原始的CSI。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过触发类型(trigger type)0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。In the study of LTE-A Release 10 (LTE-A Release 10), it is proposed that in uplink communication, non-precoded SRS, ie antenna-specific SRS, and PUSCH reference signal for demodulation should be used. (De Modulation Reference Signal, DMRS) is precoded. The first communication node can estimate the original CSI of the uplink by receiving the non-precoded SRS, and the pre-coded DMRS cannot enable the first communication node to estimate the original CSI of the uplink. At this time, when the UE transmits the non-precoded SRS by using multiple antennas, the SRS resources required by each UE are increased, which results in a decrease in the number of UEs that can be simultaneously multiplexed in the system. The UE may send the SRS by using the high-level signaling (also called triggering type trigger 0) or the downlink control information (also called trigger type 1 triggering), and the triggering is based on the high-level signaling. The SRS is triggered by the downlink control information as an aperiodic SRS. In the LTE-A Release 10, the manner of aperiodic transmission of SRS is added, which improves the utilization of SRS resources to some extent and improves the flexibility of resource scheduling.
在本公开中，提出第一通信节点可以向第二通信节点传递天线信息，以实 现第二通信节点用于发送上行信号的天线或天线组灵活切换。In the present disclosure, it is proposed that the first communication node can communicate antenna information to the second communication node to effect flexible switching of the antenna or antenna group used by the second communication node to transmit the uplink signal.

本实施例中，第一通信节点可以向第二通信节点传递天线信息，从而实现用于发送上行信号的天线或天线组的灵活切换。而且，在这种方式中，传递天线信息没有占有更多资源，从而提高了资源利用率。In this embodiment, the first communication node may transmit antenna information to the second communication node, thereby implementing flexible switching of the antenna or antenna group for transmitting the uplink signal. Moreover, in this manner, the transmission antenna information does not occupy more resources, thereby improving resource utilization.
在一实施例中，第一通信节点可以为宏小区的基站、小小区(small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点等节点，第二通信节点可以为用户终端(UE)、手机、便携设备、汽车等通信系统中的节点。In an embodiment, the first communication node may be a base station of a macro cell, a base station or a transmission node of a small cell, a sending node in a high frequency communication system, a sending node in an Internet of Things system, and the like, and a second The communication node may be a node in a communication system such as a user terminal (UE), a mobile phone, a portable device, or a car.
上行信号可以为SRS，或者为上行解调参考信号，或者为进行随机接入的上行信号，或者为PUSCH信号，或者为相位跟踪参考信号。The uplink signal may be an SRS, or an uplink demodulation reference signal, or an uplink signal for random access, or a PUSCH signal, or a phase tracking reference signal.
所述天线或天线组的信息可以是天线或天线组的标识信息、天线或天线组的端口信息，也可以是天线或天线组对应的波束标识信息。The information of the antenna or the antenna group may be the identification information of the antenna or the antenna group, the port information of the antenna or the antenna group, or the beam identification information corresponding to the antenna or the antenna group.
在一实施例中，所述第一通信节点通过DCI中已有信令指示所述天线信息，可以是通过DCI中已有信令隐含或显性指示所述天线信息。在一实施例中，隐含指示是指所述信令已有其他用途，在没有使用的情况下，可以用于指示所述天线信息。In an embodiment, the first communication node indicates the antenna information by using existing signaling in the DCI, and may explicitly or explicitly indicate the antenna information by using existing signaling in the DCI. In an embodiment, the implicit indication means that the signaling has other uses, and may be used to indicate the antenna information if not used.
在一实施例中，所述第一通信节点通过DCI中已有信令指示所述天线信息，包括：在所述DCI中携带的PUSCH资源分配信息为类型0(type 0)的情况下，通过所述DCI中的虚拟资源块向物理资源块映射比特((Virtual Resource Block，VRB)-to-(Physical Resource Block，PRB mapping bit)或跳频标识(Frequency hopping flag)指示所述天线信息。In an embodiment, the first communication node indicates the antenna information by using existing signaling in the DCI, including: when the PUSCH resource allocation information carried in the DCI is type 0 (type 0), The virtual resource block in the DCI indicates the antenna information to a physical resource block (VRB)-to-physical resource block (PRB mapping bit) or a frequency hopping flag.
本实施例中，PUSCH资源分配为type 0，下行控制信息中的VRB-to-PRB mapping bit和Frequency hopping flag没有使用，可以用于指示所述天线信息。In this embodiment, the PUSCH resource is allocated to type 0, and the VRB-to-PRB mapping bit and the Frequency hopping flag in the downlink control information are not used, and may be used to indicate the antenna information.
例如，PUSCH资源分配为type 0时，当下行控制信息中的VRB-to-PRB mapping bit或Frequency hopping flag取值为0时，则指示第二通信节点使用的天线0或天线组0发送上行信号；当下行控制信息中的VRB-to-PRB mapping bit或Frequency hopping flag取值为1时，则指示第二通信节点使用的天线1或天线组1发送上行信号。从而可以解决第二通信节点的发送链路数与接收链路数不一致时的信道互易问题，如第二通信节点配置为1T2R、2T4R、4T8R的情况。其中，T表示发送链路数，R表示接收链路数，例如1T2R表示发送链路数为1，接收链路数为2。For example, when the PUSCH resource allocation is type 0, when the VRB-to-PRB mapping bit or the Frequency hopping flag in the downlink control information is 0, the antenna 0 or the antenna group 0 used by the second communication node is sent to send an uplink signal. When the value of the VRB-to-PRB mapping bit or the Frequency hopping flag in the downlink control information is 1, it indicates that the antenna 1 or the antenna group 1 used by the second communication node transmits an uplink signal. Therefore, the channel reciprocity problem when the number of transmission links of the second communication node and the number of reception links are inconsistent can be solved, for example, the case where the second communication node is configured as 1T2R, 2T4R, and 4T8R. Where T is the number of transmit links and R is the number of receive links. For example, 1T2R indicates that the number of transmit links is 1, and the number of receive links is two.
在一实施例中，所述第一通信节点通过DCI的CRC指示所述天线信息，包括：采用天线选择掩码和所述第二通信节点对应的无线网络临时标识(Radio Network Tempory Identity，RNTI)对DCI进行CRC校验，所述天线选择掩码 指示所述天线信息。In an embodiment, the first communication node indicates the antenna information by using a CRC of the DCI, including: adopting an antenna selection mask and a Radio Network Tempory Identity (RNTI) corresponding to the second communication node. A CRC check is performed on the DCI, and the antenna selection mask indicates the antenna information.
例如，配置终端发送天线选择时，使用下表1所示的天线选择掩码和相应的RNTI对DCI进行CRC校验。For example, when configuring the terminal transmit antenna selection, the DCI is CRC checked using the antenna selection mask and the corresponding RNTI shown in Table 1 below.

When the value of the VRB-to-PRB mapping bit or the Frequency hopping flag in the downlink control information is 1, the antenna 1 or the antenna group 1 used by the second communication node transmits an uplink signal.

Where T is the number of transmit links and R is the number of receive links. For example, 1T2R indicates that the number of transmit links is 1, and the number of receive links is two.
