Definitions

  • the present disclosure relates to the field of communications technologies, and in particular, to a method for transmitting and receiving control commands, a network device, and a receiving device.
  • uplink and downlink communications for each user equipment are supported by a base station.
  • the base station accessed by the user equipment sends the data of the user equipment to the user equipment by using a downlink physical communication channel, and the user equipment demodulates the data sent to the user equipment.
  • the base station There are multiple base stations in a wireless communication network, and different base stations can use the same frequency resources to perform downlink transmission at the same time point.
  • a base station performs downlink data transmission to users in its own cell, its downlink transmission signal can occupy the same time domain and frequency domain resources as the downlink signals of other base stations. Therefore, the downlink data transmission of one base station for one user equipment may interfere with the downlink data of another user equipment for another user equipment.
  • the base station sends different signals as the target receiving device by the first user equipment and the second user equipment, respectively, and the signal sent to the second user equipment does not include the data of the receiving device with the first user equipment as the target, The signal that the two user equipment is the target receiving device may cause interference to the first user equipment.
  • the strength of the interference signal depends on a variety of factors, including cell size, transmit power strength, and the like. When the intensity of the interference signal relative to the target data signal is large, it may cause strong interference and affect the demodulation performance of the target data.
  • Interference is one of the main performance limiting factors in wireless cellular communication systems. There are two sources of interference, intra-cell interference and neighbor cell interference.
  • the neighbor cell interference is because the base station of the neighboring cell schedules other users of the neighboring cell at the same frequency. The interference of this cell is larger for users at the edge of the cell.
  • the interference of the cell mainly comes from the fact that one base station (eNB) can transmit data to different user equipments in the same time domain/frequency domain resource, and adopt the same or different beam shaping moments for different user equipments.
  • Array using the distinction of user equipment on the airspace or other scales to achieve multiple access.
  • the two user equipments can use different beamforming matrices; if the beamforming matrix of one user equipment and the signal orthogonality of another user equipment are better, the local cell interference It can be reduced; the downlink MU-MIMO (Multi-User Multiple Input Multiple Output) of LTE in the related art is based on this method.
  • MU-MIMO Multi-User Multiple Input Multiple Output
  • Another possible MU-MIMO method is to configure different user equipments with different power or spreading codes/sequences by means of power or spreading codes. User equipment interferes with each other through advanced receivers.
  • a target receiving device demodulates only the data sent to itself; for the data transmitted by the network to other receiving devices, that is, the interference signal received by the target receiving device, the target receiving device does not demodulate or eliminate/ Suppress processing.
  • the receiving device here is any user device that can receive a signal transmitted by a network device such as a base station.
  • advanced terminal receivers have gradually become a possibility.
  • advanced terminal receivers can jointly process the signals of the target receiving device and the signals interfering with the user equipment (ie, the target receiving device receives Interference signal), the interference signal is eliminated, suppressed, canceled, etc., to improve the performance of the target receiving device signal reception.
  • interference within a cell can be eliminated by an advanced terminal receiver. Eliminating interference in the cell (that is, interference between different users) requires knowledge of the parameters of the interference signal. These parameters can be achieved by the blind detection of the receiving device itself, but the complexity is high.
  • the dynamic downlink control signaling sent by the network to the UE in the LTE system in the related art is called downlink control information (DCI).

  • the DCI control signaling sent by the network device to a target receiving device includes only the transmission parameter information of the data of the receiving device. Assuming that UE A is the target receiving device, the DCI (denoted as DCI A) sent to UE A only contains the transmission parameter information that UE A accepts its data, which is represented as ControlInfo-Self information, and has X bits.
  • the UE may also be configured by the network to receive a signal transmission parameter information of UE B (including DCI B of ControlInfo-Interf), but whether the user is used in one subframe. The behavior of ControlInfo-Interf for interference cancellation is dynamically changeable.
  • the network device always sends the transmission parameter information ControlInfo-Interf of the interference signal to the target user UE A, but at some time UE A needs to use ControlInfo-Interf for interference cancellation, and sometimes UE A does not use ControlInfo- Interf performs interference cancellation.

  • the SNR can be changed in the interference cancellation and interference cancellation. Very big. If the network considers that the user has performed interference cancellation and schedules a higher MCS, and the user does not perform interference cancellation, the user's data may not be accurately received, and the performance is greatly degraded. If the network considers that the user has no interference cancellation and schedules a lower MCS, the user cannot achieve the data rate that it should have, and it also affects system performance.

控制信令的发送、接收方法、网络设备及接收设备
相关申请的交叉引用
本申请主张在2015年8月25日在中国提交的中国专利申请号No.201510526731.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种控制指令的发送、接收方法、网络设备及接收设备。
背景技术
无线通信系统中，每一个用户设备的上行和下行通信由一个基站支持。在下行方向，用户设备接入的基站将该用户设备的数据通过下行物理通信信道发送给该用户设备，用户设备对发送给自己的数据进行解调。
一个无线通信网络中有多个基站，不同基站可以使用同样的频率资源在同样的时间点进行下行传输。当一个基站对自己小区内的用户进行下行数据传输的时候，其下行发送信号可以和其他基站的下行信号占用同样的时域和频域资源。由此，一个基站针对一个用户设备的下行数据传输，可能对另外一个基站针对另外一个用户设备的下行数据产生干扰。简言之，基站以第一用户设备和第二用户设备分别作为目标接收设备发送不同的信号，发送给第二用户设备的信号不包含以第一用户设备为目标接收设备的数据，则以第二用户设备为目标接收设备的信号对第一用户设备可能会产生干扰。
干扰信号的强度取决于多种因素，包括小区大小，发送功率强弱等等。当干扰信号相对于目标数据信号的强度较大时，有可能造成强烈的干扰，影响目标数据的解调性能。
干扰是无线蜂窝通信系统中的主要性能限制因素之一。干扰有两种来源，小区内干扰和邻小区干扰。邻小区干扰是因为邻小区的基站在同样的频率调度了邻小区的其它用户。本小区干扰对小区边缘的用户较大。
本小区干扰主要来自于一个基站(eNB)可以在相同的时域/频域资源对不同的用户设备进行数据传输，对不同用户设备采用相同或者不同的波束赋形矩 阵，利用用户设备在空域上或者其它尺度上的区分实现多址接入。在用户空间信道区分较好的情况下，两个用户设备可以使用不同的波束赋形矩阵；如果一个用户设备的波束赋形矩阵和另一个用户设备的信号正交性比较好，则本小区干扰可以有所降低；相关技术中的LTE的下行MU-MIMO(多用户多输入多输出)正是基于此种方式。
另一种可能的MU-MIMO方式是通过功率或者扩频码的方式，将不同用户设备配置不同的功率或者是扩频码/序列。用户设备通过高级接收机互相抵消之间的干扰。
传统通信技术中，一个目标接收设备只对发送给自己的数据进行解调；对于网络发送给其他接收设备的数据，即目标接收设备接收到的干扰信号，目标接收设备不进行解调或者消除/抑制处理。这里的接收设备是可以接收到网络设备(如基站)发送的信号的任何一个用户设备。
随着技术的进步，高级终端接收机逐渐成为一种可能，和传统的终端接收机相比，高级终端接收机可以共同处理目标接收设备的信号和干扰用户设备的信号(即目标接收设备收到的干扰信号)，对干扰信号进行消除，抑制，抵消等处理，提高目标接收设备信号接收的性能。
在无线通信系统中，小区内的干扰可以通过高级终端接收机来实现消除。消除小区内的干扰(也就是不同用户之间的干扰)，需要知道干扰信号的参数。这些参数可以通过接收设备盲检自身实现，但是复杂度很高。
相关技术中的LTE系统中网络给UE发送的动态下行控制信令称为downlink control information(DCI)。DCI包括网络调度UE进行数据接收的传输参数信息，比如在哪些频段进行数据传输，数据的调制阶数(QPSK/16QAM/64QAM)，TBS(transport block size，传输块大小)等。DCI在空口通过PDCCH发送(physical downlink control channel，物理下行控制信道)，UE盲检PDCCH获得其自身的DCI信息。
网络设备发送给一个目标接收设备的DCI控制信令只包括该接收设备的数据的传输参数信息。假设UE A为目标接收设备，则发送给UE A的DCI(表示为DCI A)只包含UE A接受其数据的传输参数信息，表示为ControlInfo-Self信息，有X比特。UE可能还会被网络配置接收一个UE B的信号传输参数信息(包含ControlInfo-Interf的DCI B)，但是用户是否在一个子帧内使用 ControlInfo-Interf进行干扰消除的行为是可以动态变化的。反言之，网络设备总是将干扰信号的传输参数信息ControlInfo-Interf发送给目标用户UE A，但是在某些时候UE A需要使用ControlInfo-Interf进行干扰消除，某些时候UE A不使用ControlInfo-Interf进行干扰消除。另外，网络调度的MCS(Modulation and Coding Scheme，调制与编码策略)也和网络预期UE接收的SNR(Signal Noise Ratio，信噪比)直接相关，SNR在干扰消除和不进行干扰消除时的变化可以非常大。如果网络认为用户进行了干扰消除，调度了较高的MCS，而用户没有进行干扰消除，则用户的数据很有可能无法准确接收到，性能下降很大。如果网络认为用户没有干扰消除，调度较低的MCS，则用户无法实现其应有的数据速率，也会影响系统性能。
相关技术中，用户接收设备根据自身的盲检，获得自身数据接收的传输参数信息，无法对该用户接收设备受到的干扰信号进行消除处理；即使用户接收设备被配置为接收干扰用户设备的信号的传输参数信息，用户接收设备利用干扰用户设备的信号的传输参数信息进行干扰信号消除处理也是动态变化的，无法和网络调度的MCS匹配，从而影响用户接收设备的数据速率，也会影响系统性能。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附 图及具体实施例进行详细描述。
本公开针对相关技术中的系统中，接收设备进行干扰信号的处理时，无法受到网络侧的控制，从而影响数据速率的问题。本公开的实施例提供一种控制信令的发送、接收方法、网络侧设备及接收设备，从而可以实现网络侧设备可以控制接收设备是否使用网络侧设备通知的控制指令对其受到的干扰信号进行消除处理，从而保证接收设备的数据速率。
需要澄清的是，本公开的实施例中“消除”是一种信号处理手段的统称，可以包括但不仅限于消除，抑制，抵消，处理等多种可能的操作。
如图1所示，本公开的一些实施例提供一种控制信令的发送方法，包括：
步骤11，获取针对第一信号进行处理的控制指令，所述第一信号携带不以接收设备为目标接收设备的信号；如，基站以第一接收设备和第二接收设备分别作为目标接收设备发送不同的信号，发送给第二接收设备的信号不包含以第一接收设备为目标接收设备的数据，则以第二接收设备为目标接收设备的信号对第一接收设备可能会产生干扰；该第一信号可以是该接收设备受到的干扰信号；
步骤12，将所述控制指令发送给所述接收设备，所述控制指令用于控制所述接收设备是否对第一信号进行处理。
本公开的一些实施例通过网络侧设备将对目标接收设备接收到的第一信号是否进行处理的控制指令发送给接收设备，使得接收设备可以依据该控制指令对其接收到的第一信号是否进行处理，该第一信号携带不以该接收设备为目标接收设备的信号；通常来讲，该接收设备接收到的不以该接收设备为目标接收设备的信号为该接收设备接收到的干扰信号，依据该控制指令可以判断是否对该干扰信号进行消除。从而实现网络侧设备可以控制接收设备是否使用网络侧设备通知的控制指令对其受到的干扰信号进行消除，从而保证设备的数据速率。
本公开的一些实施例中，所述控制指令包括：第一信号的至少一个数据流的控制信息。进一步的，该控制信息具有所述接收设备对第一信号进行处理的第一状态或者所述接收设备对所述第一信号不进行处理的第二状态，其中，第一状态与第二状态不同。
例如，该控制信息为1比特，则该1比特为0时，表示第一状态；该1比 特为1时，表示第二状态；其中，第一状态可以表示该接收设备依据该控制指令对第一信号携带的干扰信号进行消除或者不消除；第二状态可以表示该接收设备依据该控制指令对第一信号携带的干扰信号进行不消除或者消除。
该控制信息还可以为n比特的序列，所述序列中的每一比特用于表示所述第一信号的至少一不同数据流的控制信息，n＞1。
例如，通过一个独立的控制信令的比特域来通知接收设备开/关干扰消除行为，网络设备(基站)发送给接收设备的下行控制信令包括1比特的干扰消除行为开关控制指令：
如果比特位的第一状态为：0，接收设备不需要进行干扰消除。
如果比特位的第二状态为：1，接收设备进行干扰消除。
相关技术中的通信系统中支持多天线MIMO系统(multiple input，multiple output)，一个基站具有多根天线，可以发送多个数据流。同理，干扰信号可以包含一个数据流，也可以包括多个数据流。下行控制指令通知接收设备的开/关干扰消除信号，可以对一个数据流进行控制，也可以对多个数据流进行控制。
其中，所述比特可以是对应发送给所述接收设备的数据流的一个控制比特；如果用户有n个数据流，以上控制指令可以对n个数据流单独发送。
例如，eNB(基站)可以发送1比特通知UE对所有的干扰数据流进行干扰处理，当比特为1时，UE对所有的干扰数据流进行消除，当比特为0时，UE对所有的干扰数据流进行消除。此时一个比特控制所有干扰数据流的消除处理。另外一个实施例，eNB(基站)发送一个n比特的序列给接收设备，对应M流数据，每个比特通知目标接收设备是否对相应的数据流进行干扰消除。本公开的一些实施例中，eNB发送一个n比特的序列给用户，控制n流干扰数据的消除，n＜M，每个比特和不同数据流的对应关系有网络和用户设备提前约定，或者通过高层信令通知UE。本公开的一些实施例中，n＝2，M＝4，第一比特控制第一流和第二流的干扰消除，第二比特控制第三流和第四流的干扰消除。
所述控制信息还可以通过下行控制信令中的一个空闲状态表示。如干扰消除的开/关信令和其他控制信令一起编码。比如，MCS信令(Modulation coding scheme)的一个状态、TBS索引或者是其他任意参数的一个状态，这里不一一赘述，可以用来指示UE是否进行干扰消除。比如LTE网络中，MCS信令由5 比特发送，对应32个MCS等级。但是实际系统中只有少于32个MCS等级被使用到，一些MCS等级现在被预留。其中预留的MCS状态/等级可以用来通知终端关闭/开启干扰消除。需要注意这里的MCS是干扰信号的MCS参数，由基站设备通过下行信令通知UE，不是终端自身数据信号的MCS参数。
本公开的一些实施例中，对于SIC接收机，网络可以通过下行信令通知接收设备其可能接收到的干扰信号的调制序列，比如QPSK，16QAM，64QAM。假设系统不支持256QAM信号干扰消除，则干扰信号的QAM可以由两个bit在下行信令(controlinfo-interf)中通知给接收设备。两个bit对应4个状态，但是干扰信号的调制序列只有三个状态(QPSK，16QAM，64QAM)，则剩余的一个一个QAM等级用来通知终端关闭干扰消除，如下表：
Figure PCTCN2016092348-appb-000001
当接收设备接受到2比特下行信令的值为0，1，2时，接收设备理解干扰信号的调制为QPSK，或16QAM，或64QAM，然后对干扰信号进行消除。当2bit下行信令的值为3时，目标终端对干扰信号不进行消除，干扰消除行为关闭。
当干扰信号包含n个数据流的时候，以上实施例可以对每个数据流适用，即对于每个数据流，下行控制信令通过2-bit通知UE干扰信号的QAM等级和干扰消除行为。
如图2所示，本公开的一些实施例提供一种控制信令的发送方法，包括：
步骤21，获取针对第一信号进行处理的控制指令，所述第一信号携带不以接收设备为目标接收设备的信号；所述控制指令用于控制所述接收设备是否对第一信号进行处理；如，基站以第一接收设备和第二接收设备分别作为目标接收设备发送不同的信号，发送给第二接收设备的信号不包含以第一接收设备为目标接收设备的数据，则以第二接收设备为目标接收设备的信号对第一接收设备可能会产生干扰；该第一信号可以是该接收设备受到的干扰信号；
步骤22，获取所述第一信号的第一传输参数信息；
步骤23，将所述第一传输参数信息和所述控制指令发送给接收设备。
其中，步骤23中，可以将第一传输参数信息和所述控制指令，分别发送给所述接收设备；或者对第一传输参数信息和控制指令联合编码，得到第一编码信息，并将所述第一编码信息发送给接收设备。
本公开的一些实施例中，通过网络设备将接收设备进行干扰信号消除的第一传输参数信息发送给接收设备，使得接收设备可以依据第一传输参数信息对其受到的干扰信号进行消除。
本公开的一些实施例中，所述第一传输参数信息包括：与所述接收设备处于同一小区的第一设备的第一数据接收参数信息，也可以是与所述接收设备不处于同一小区的第二设备的第二数据接收参数信息；
接收设备可以被RRC(无线资源控制)信令配置为不同的传输模式(TM)，不同的传输模式对应于不同的DCI(下行控制信令)格式。TM和DCI格式是一一对应的，接收设备在被配置了TM之后，在每一个子帧进行接收设备的DCI A盲检，如果盲检成功，接收设备理解网络侧对其发送了相应的DCI格式，使用DCI A中的数据的传输参数信息进行PDSCH(物理下行共享信道)数据的接收。
如果接收设备要进行干扰信号的消除，网络设备也配置该接收设备需要准备进行干扰消除，则接收设备需要知道干扰信号的传输参数信息(controlinfo-interf)，即需要知道第一设备的第一数据接收参数信息；因此，网络侧基站将与所述接收设备处于同一小区的第一设备的第一数据接收参数信息发送给接收设备，此时接收设备盲检DCI B，该DCI B携带有第一设备的第一数据接收参数信息，接收设备尝试获得第一设备的第一数据接收参数信息。
接收设备在获得第一设备的第一数据接收参数信息后，可以对该第一设备的干扰信号进行消除。
具体消除时，可以采用如下消除方法对第一设备的干扰信号的消除：依据第一设备的第一数据接收参数信息对第一设备的干扰信号进行某种程度的解调，甚至解码，然后利用接收机的处理增益从接收信号中消除干扰信号分量。
本公开的一些实施例中的接收设备对其受到的干扰信号的消除方法，同样适用于本公开的其它各个实施例中。

假设小区内有两个UE，分别是：UE A，UE B。在一个子帧中，UE A和UE B在一起调度，UE A是近端用户，UE B是远端用户，UE A需要消除UE B带来的干扰，当然，UE B也可以是与UE A不在同一小区的UE；UE A使用网络设备发送给UE A的控制指令确定是否对UE B带来的干扰进行信号消除处理，其中，UE A接收网络设备发送的ControlInfo-Interf(即UE B的信号的传输参数信息)，从而在控制指令允许UE A进行干扰信号的消除处理时，该UE A就可以依据UE B的信号的传输参数信息ControlInfo-Interf进行干扰信号的消除处理。此时，基站可以依据该控制指令允许UE A进行干扰信号的消除处理时，调度与该UE A进行干扰信号消除时的SNR相匹配的MCS，从而保证UE A的数据速率，提高系统性能；而相关技术中网络设备无法调度与UE A进行干扰信号消除处理时的SNR相匹配的MCS。
