Description

一种数据传输的方法、装置及系统
本申请中要求在2017年09月08日提交中国专利局、申请号为201710806421.7、申请名称为“一种数据传输的方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种数据传输的方法、装置及系统。
背景技术
动态时分双工(dynamic time division duplexing，D-TDD)系统中，终端设备间还可能存在交叉链路干扰，这是由于在D-TDD系统中对于同一时隙(slot)来说，不同基站下的终端设备的数据传输方向有可能是不同的。
示例的，如图1所示在slot1上，基站1向小区1中终端设备1发送下行数据，小区2中终端设备2向基站2发送上行数据，其中小区1为基站1的服务小区，小区2为基站2的服务小区。在如图1所示的通信场景中终端设备2发送的上行数据会对终端设备1接收的下行数据造成干扰，该干扰即为终端设备1和终端设备2间的交叉链路干扰。当终端设备1和终端设备2间的交叉链路干扰较为严重时，则有可能导致终端设备1通信失败。现有技术中为了降低终端设备间的交叉链路干扰，使得处于接收状态的终端设备能够正常通信，处于发送状态的终端设备在当前slot向基站发送数据前，先进行侦听，若侦听到的信号强度超过某个门限值后，则该终端设备不在当前slot上发送数据，若侦听到的信号强度未超过该门限值，则该终端设备在当前slot上向基站发送数据，然而这种方式虽然在一定程度上降低了终端设备间的交叉链路干扰，但是由于在侦听到的信号强度超过某个门限值的情况下，该终端设备不能够在当前slot上发送数据，容易浪费了基站为终端设备配置的时频资源。

具体实施方式
下面结合说明书附图对本申请实施例进行详细介绍。
应理解，本申请实施例中所涉及的网络设备，可以是基站、或者接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。当网络设备为基站时，基站可用于将收到的空中帧与网际协议(internet protocol，IP)分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站还可用于协调对空中接口的属性管理。例如，基站可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)系统中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的节点B(node B)，还可以是长期演进(long term evolution，LTE)系统中的演进型基站(evolutional node B，eNB)，亦或是下一代无线通信(next radio，NR)系统中的gNB，本申请实施例不作限定。
应理解，本申请实施例中的终端设备可以为用于向用户提供语音和/或数据连通性的设备、或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。本申请实施例中的终端设备还可以为无线终端，其中，无线终端可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或 称为“蜂窝”电话)、或具有移动终端的计算机，例如，具有移动终端的计算机可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，无线终端还可以为个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。无线终端也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户装备(user equipment)等，本申请实施例不作限定。
应理解，本申请实施例中的数据传输格式中规定了数据发送前数据的调制方式、传输块(transport block，TBS)的大小、编码版本、传输内容、以及传输内容各个部分所占的比特数等，示例的，本申请实施例中数据传输格式可以称之为调制编码策略(modulation and coding scheme，MCS)，也可以称之为传输格式(transport format，TF)等，对此本申请实施例不作限定。
应理解，本申请实施例可以应用于但不限于D-TDD系统中，如NR系统、LTE系统、长期演进高级(long term evolution-advanced，LTE-A)系统、增强的长期演进技术(enhanced long term evolution-advanced，eLTE)等通信系统中，还可以扩展到如无线保真(wireless fidelity，WiFi)、全球微波互联接入(worldwide interoperability for microwave access，wimax)、以及第三代合作伙伴计划(3rd generation partnership project，3GPP)等相关的蜂窝系统中，也可以应用到Internet组网的通信系统中，具体的本申请实施例所应用的通信系统架构可以如图2所示，包括基站和至少一个终端设备，需要说明的是，本申请实施例中不限定图2中所示通信系统中终端设备的个数。
由于在如图2所示的通信系统架构中，不同的基站下的终端设备在同一时间/子帧上，不同基站下的终端设备的数据传输方向有可能是不同的，因此终端设备间可能存在交叉链路干扰，为了降低终端设备间的交叉链路干扰，本申请实施例提供了一种数据传输的方法。
示例的，如图1所示的通信场景，在slot1上，基站1向小区1中终端设备1发送下行数据，小区2中终端设备2向基站2发送上行数据，其中小区1为基站1的服务小区，小区2为基站2的服务小区。在如图1所示的通信场景中终端设备2发送的上行数据会对终端设备1接收的下行数据造成干扰，该干扰即为终端设备1和终端设备2间的交叉链路干扰。
下面为了表述方便，在本申请实施例中，以网络设备为基站举例进行详细说明，这仅是本申请实施例所举的例子，当网络设备为其它设备时，与网络设备为基站时类似，在此不再赘述。
以图1所示的通信场景为例对本申请实施例的数据传输的方法进行详细说明。
如图3所示，本申请实施例数据传输的方法，包括：
步骤300，基站2向终端设备2发送配置信息，该配置信息包括N个调整方式，其中调整方式用于调整第一数据传输格式，第一数据传输格式为基站2指示给终端设备2的、且终端设备2用于向基站2发送数据所使用的数据传输格式，N为正整数。
步骤301，终端设备2在接收到基站2发送的配置信息后，根据测量结果，从N个调 整方式中选择第一调整方式，其中测量结果是终端设备2对信号测量得到的。
步骤302，终端设备2根据第一调整方式，确定将第一数据传输格式调整为第二数据传输格式，第一数据传输格式是基站2指示给终端设备2的，且第二数据传输格式对应的发射功率小于第一数据传输格式对应的发射功率。
步骤303，终端设备2根据第二数据传输格式向基站2发送数据，然后基站2接收终端设备2发送的数据。
需要说明的是，在步骤303中，由于终端设备2向基站2发送的数据的实际数据传输格式与基站2指示给终端设备2的数据传输格式发生了变化，基站2在接收到终端设备2发送的数据后，可以基于下列方式对数据进行解调：
一种方式为：基站2通过盲检的方式来检测终端设备2向基站2发送的数据所使用的数据传输格式，然后对数据进行解调，具体的，基站2可以根据预先配置给终端设备2的资源块的大小来预知可能的数据传输格式，基站2也可以通过检测循环冗余校验(cyclic redundancy check，CRC)来判断终端设备2使用的数据传输格式，此外，另一种方式为：终端设备2通过信令消息通知基站2发送数据所使用的资源块长度、编码方式等数据传输格式信息，具体的信令消息可以为控制信息，该控制信息可以携带在物理上行控制信道(physical uplink control channel，PUCCH)中，基站2根据该信令消息对终端设备2发送的数据进行解调。
还需要说明的是，终端设备2对信号测量得到测量结果，在本申请实施例中，可选的，测量结果用于指示接收信号的接收功率，也可以用于指示信号的接收强度或者信噪比等，其中该信号为终端设备1或者其它终端设备(如终端设备1)发送给终端设备2的，该信号也可以为其它网络设备(如基站1)发送给终端设备2的。
具体的，以终端设备1发送给终端设备2的信号为例，通常情况下，终端设备1在接收到基站1发送的下行控制信息(downlink control information，DCI)之后，确定需要接收数据，则在接收数据之前发送该信号，其中该信号可以为参考信号(reference signal，RS)(如小区特定参考信号(cell-specific reference signals，CRS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)等)、探测信号或者定义的其它信号等。以图1所示的通信场景为例，可选的，可通过下列方式实现信号的发送和测量：
基站2为终端设备2配置第一资源，终端设备2在第一资源上接收信号，基站1为终端设备1配置第二资源，终端设备1在第二资源上发送信号，其中，在第一资源上接收的信号和在第二资源上发送的信号的名称可以相同，也可以不同，示例的，在第一资源上接收的信号可称之为测量信号，在第二资源上发送的信号可称之为探测参考信号(sounding reference signal，SRS)。相应的，第一资源和第二资源的名称也可以相同，或者也可以不同，示例的，第一资源称之为干扰测量资源(interference measurement resource，IMR)，第二资源称之为参考信号资源。下面以终端设备1在第二资源上发送的信号、终端设备2在第一资源上接收的信号均称之为参考信号进行相应的说明。
示例的，如图4a所示，基站2配置的第一资源的位置可以位于调度下行控制信息(downlink control information，DCI)的资源之后，占用一个或多个符号，具体的，第一资源的符号位置、序列、调制方式、功率配置等由基站2配置。具体的，基站2配置的参数与测量结果有关，示例的，若测量结果为接收的信号强度指示(received signal strength indication，RSSI)，则基站2需要配置第一资源的符号位置，若测量结果为参考信号接收 功率(reference signal receiving power，RSRP)，则基站2除了配置第一资源的符号位置、还需要配置序列、调制方式、循环移位等参数。如图4b所示，基站1配置的第二资源的位置也可以位于调度DCI的资源之后，占用一个或者多个符号。
当终端设备1在接收到的DCI后，若确定DCI中包括用于调度下行数据的信息，则终端设备1在接收下行数据之前，在第二资源上发射参考信号，用于终端设备2进行信号测量。
终端设备2通过第一资源接收终端设备1发送的参考信号，并测量该参考信号的接收功率。
在本申请实施例中，终端设备2在向基站2发送数据前，进行信号测量，有可能会在第一资源上接收到来自多个设备发射的参考信号，如果终端设备2具备区分这些信号的能力，则分别测量这些参考信号的接收功率，为了降低与这些设备间交叉链路干扰，通常将测量得到的接收功率中的最大接收功率作为终端设备2信号测量的测量结果。如果终端设备2不具备区分这些信号的能力，则将测量得到的总接收功率作为终端设备2信号测量的测量结果。
可选的，在本申请实施例中，第一资源的时频位置和第二资源的时频位置是基站预先配置给终端设备的；或者，可选的，由于调度信息中包含了终端设备用于数据传输的频域资源的物理资源块(physical resource block，PRB)的序号，因此终端设备2可根据终端设备用于数据传输的PRB的序号、结合第一资源的符号位置，在第一资源上接收参考信号，或者终端设备1可根据终端设备用于数据传输的PRB的序号、结合第二资源的符号位置，在第二资源上发送参考信号；示例的，终端设备1用于数据传输的PRB的序号为[0、1、2、3]，则终端设备1在序号为[0、1、2、3]的PRB上发送参考信号，终端设备2用于数据传输的PRB的序号为[1、2、3、4]，则终端设备2在序号为[1、2、3、4]的PRB上接收参考信号。
此外，还需要说明的是，在本申请实施例中，测量结果还可以用于指示接收参考信号的信号强度等，对此本申请实施例中不进行限定。
步骤301中，终端设备2根据测量结果，从N个调整方式中选择第一调整方式，然后当测量结果较小时，终端设备2发送的数据对其它设备造成的交叉链路干扰可忽略，因此无需进行数据传输格式的调整，可选的，终端设备2在确定测量结果与第一门限值之间的大小关系满足第一预定大小关系后，确定第一差值，其中第一差值为测量结果与第一门限值之间的差值，然后终端设备2根据第一差值，从N个调整方式中选择第一调整方式。若终端设备2确定测量结果与第一门限值之间的大小关系不满足第一预定大小关系后，则根据第一数据传输格式向基站2发送数据。
需要说明的是，当测量结果指示的是信号的接收功率时，第一预定大小关系指的是测量结果大于第一门限值，当测量结果指示的是信噪比时，第一预定大小关系指的是测量结果小于第一门限值，在具体实现时，第一预定大小关系可根据测量结果进行相应的设定，本申请实施例对此不作限定。
还需要说明的是，在本申请实施例中，第一门限值可以为基站2指示给终端设备2的，也可以是预先定义好的，当第一门限值为基站2指示给终端设备2时，可选的，可以通过携带N个数据传输格式的调整方式的配置信息中发送给终端设备2，也可以通过其他信令发送给终端设备2，对此不进行限定。
此外，第一门限值的取值与终端设备1发送参考信号的发射功率相对应，当终端设备1发送参考信号的发射功率发生变化时，第一门限值得取值也可能发生变化，具体的第一门限值的取值与终端设备1发送参考信号的发射功率之间的关系可以预先约定。
在本申请实施例中，一种可选的确定终端设备1发送参考信号的发射功率的方式为：根据最近上行信道发射功率加上一个偏移值(offset)，该offset可以由基站1配置，可选的，基站1可以根据小区1范围的大小来配置offset；另一种可选的确定终端设备1发送参考信号的发射功率的方式为：使用预定义的绝对功率值作为终端设备1发送参考信号的发射功率，由基站1向终端设备1指示一个绝对功率值。或者，由基站配置M个绝对功率值，M为正整数，由基站1向终端设备1指示使用M个绝对功率值中的哪一个绝对功率值。示例的，M取值为3，假设绝对功率值分别为10、12和9，若基站1向终端设备1指示绝对功率值为10，则终端设备1采用功率为10的发射功率发射参考信号。
示例的，当终端设备1发送参考信号的发射功率为功率1时，若功率1对应第一门限值1，则基站2向终端设备2指示第一门限值1。
本申请实施例中当终端设备2在测量结果与该第一门限值之间的大小关系满足第一预定大小关系时，说明终端设备2对终端设备1造成的交叉链路干扰较大，通过调整数据传输格式来降低终端设备2对终端设备1造成的交叉链路干扰的同时，提高了时频资源的利用率。
示例的，假设第一门限值为T dB，测量结果为R dB，若第一预定义关系为测量结果大于第一门限值，则当R>T时，终端设备2可基于(R-T)来确定需要下调的数据的发射功率。
一种可选的从N个调整方式中选择第一个调整方式的实现方式为：
终端设备2根据第一差值确定第二差值，第二差值为终端设备2调整前的数据传输格式和终端设备2调整后的数据传输格式分别对应的发射功率之间的最小差值，然后终端设备2根据第二差值，从N个调整方式中选择第一调整方式，其中第一数据传输格式对应的发射功率与根据第一调整方式确定的第二数据传输格式对应的发射功率之间的差值不小于第二差值。
其中，第二差值与第一差值之间的函数关系可以预先约定好，例如第二差值为因变量，第一差值为自变量，其满足函数关系f(x)＝x，则第二差值与第一差值大小相等，此外，根据实际情况的需要，本申请实施例中第二差值与第一差值之间的函数关系还可以为其它的函数关系，对此不进行限定。此外，还可以预先设置第二差值与第一差值之间的对应关系，例如差值范围对应一个差值，当第一差值在某一个差值范围内时，则第二差值为第一差值所在的差值范围对应的差值。
示例的，可以按照如下方式选择调整方式：
具体的，第三代合作伙伴计划(3rd generation partnership project，3GPP)TS 36.213V8.6.0中规定终端设备2在物理上行共享数据信道(physical uplink shared channel，PUSCH)上在子帧/时隙i上发射功率的计算方式为：
P(i)＝min{P CMAX(i),10log 10(M PUSCH(i))+P O_PUSCH(j)+α(j)·PL+Δ TF(i)+f c(i)}
其中，P CMAX(i)为终端设备2在子帧/时隙i上的最大发射功率；M PUSCH(i)在子帧/时隙i中PUSCH所占的带宽，单位为资源块(resource block，RB)；P O_PUSCH(j)高层配置参数， j的取值可以为0、1或2，由高层决定j的取值，当j的取值可以为0或1时，α(j)为小区级参数，当j的取值可以为2时，α(j)＝1；PL为下行路损值；在本申请实施例应用于Ks为非0的通信场景下，

K s＝1.25 ，
Figure PCTCN2018104020-appb-000002
C为基站2为终端设备2配置的所码块的个数，K r为第r个码块的大小，N RE为终端设备2传输数据使用的码块的个数。
其中终端设备2向基站2发送数据所使用的发射功率调整可以通过调整K r的大小，来使得调整前后的发射功率差不小于第二差值。
而K r的大小可以通过调整数据传输格式进行相应的调整，其中在本申请实施例中数据传输格式中规定了终端设备向基站发送的数据的码块大小、调制方式、传输速率等。具体的，数据传输格式称之为调制编码策略(modulation and coding scheme，MCS)，也可以直接称之为传输格式等，对此本申请实施例不进行限定。
以MCS为例，假设N取值为4，则N个调整方式可以如表1所示。
表1
调整方式 MCS索引
Format 0 MCS-3
Format 1 MCS-5
Format 2 MCS-7
Format 3 MCS-9
Format 4 MCS-11
假设第一数据传输格式为MCS-1，则可以从表1中任意选择一个调整方式，如Format 0，计算MCS索引为MCS-3时终端设备2的发射功率，比较MCS-1对应的发射功率与MCS-3对应的发射功率之间的差值是否不小于第二差值，若该差值不小于第二差值，则第一调整方式为Format 0，然后终端设备2可以将第MCS-1调整为MCS-3；此外，还可以计算表中所有调整方式下的发射功率，计算第一数据传输格式对应的发射功率分别与不同调整方式下的发射功率的差值，从所有差值中选择不小于第二差值中的最大值所对应的调整方式，示例的，表1中Format 3和Format 4满足要求时，若第一数据传输格式对应的发射功率与MCS-9对应的发射功率间的差值大于第一数据传输格式对应的发射功率与MCS-11对应的发射功率间的差值，则第一调整方式为Format 3。
由于在本申请实施例中，在通过调整数据传输格式来调整数据的发射功率，因此能够在满足误码率(block error ratio，BLER)性能的要求下，在降低终端设备间交叉链路干扰的同时，提高时频资源的利用率。
此外，在该种实现方式下，基站还可以向终端设备发送预先配置多个调整方式表，终端设备可以从多个调整方式表中选择一个进行数据传输格式的调整，具体的由于基站在给终端设备配置了不同大小的时频资源时，为了保证BLER性能不变，不同大小的时频资源下同样的上行接收信号信噪比调整所需要的调整到的MCS可能不同，因此终端设备可以根据时频资源的大小从多个调整方式表中选择一个调整方式表，终端设备还可基于其他参数来选择使用哪个调整方式表进行数据传输格式的调整，示例的，基站还可以向终端设备发 送表1和表2，当时频资源块的大小为A时，终端设备选择表1，当时频资源块的大小为B时，终端设备选择表2。

此外，另一种可选的从N个调整方式中选择第一调整方式的实现方式为：
N个调整方式分别对应一个差值范围，终端设备2根据第一差值确定第三差值，并根据第三差值从N个调整方式中，选择第一调整方式，其中第一调整方式为与第三差值所在的差值范围对应的调整方式。其中第三差值为终端设备2调整前的数据传输格式和终端设备2调整后的数据传输格式分别对应的发射功率之间的最小差值，具体的第三差值的计算方式与一种可选的从N个调整方式中选择第一调整方式的实现方式中第二差值的计算方式类似，在此不再赘述。
示例的，假设N取值为4，N个调整方式分别对应一个差值范围如表4所示。

示例的，若第三差值为P1，在[-Po1,-Po2)中，则终端设备2选择的第一调整方式为Format1。
具体的，可以根据Format 1来计算终端设备2向基站2的发射功率的方式可以参见3GPP TS 36.213V8.6.0中规定终端设备2在物理上行共享数据信道(physical uplink shared channel，PUSCH)上在子帧/时隙i上发射功率的计算方式，也可以按照如下方式计算：
P(i)＝min{P CMAX(i),10log 10(M PUSCH(i))+P O_PUSCH(j)+α(j)·PL+Δ TF(i)+f c(i)+ΔP}
其中，P CMAX(i)为终端设备2在子帧/时隙i上的最大发射功率；M PUSCH(i)在子帧/时隙i中PUSCH所占的带宽，单位为资源块(resource block，RB)；P O_PUSCH(j)高层配置参数，j的取值可以为0、1或2，由高层决定j的取值，当j的取值可以为0或1时，α(j)为小区级参数，当j的取值可以为2时，α(j)＝1；PL为下行路损值；

此外，本申请实施例中可选的从N个调整方式中选择第一调整方式的实现方式还可以为：N个调整方式分别对应一个差值范围，终端设备2从N个调整方式中，选择第一调整方式，其中第一调整方式为与第一差值所在的差值范围对应的调整方式，第一差值为测量结果与第一门限值之间的差值。
示例的，以表2为例，若第一差值为P2，在[-Po2,-Po3)中，则终端设备2选择的调整方式为Format2。
本申请实施例中，还需要说明的是，假设N取值为3，则N个调整方式还可以如表5所示，例如，第一数据传输格式的MCS索引为9，若选择的第一调整方式为Format1，则终端设备将第一数据格式调整为的第二数据传输格式的MCS索引为4。

本申请实施例中，若终端设备2确定测量结果与第二门限值之间的大小关系满足第二预定大小关系，则向基站2发送预先配置的测量上报格式规定的传输内容。
需要说明的是，当测量结果指示的是信号的接收功率时，第二预定大小关系指的是测量结果大于第二门限值，在这种情况下，第二门限值大于第一门限值；当测量结果指示的是信噪比时，第二预定大小关系指的是测量结果小于第二门限值，在这种情况下，第一门限值大于第二门限值，在具体实现时，第二预定大小关系可根据测量结果进行相应的设定，本申请实施例对此不作限定。
其中，第二门限值可以预定义，也可以由网络设备配置给第一终端设备，具体的，网络设备通过配置信息向第一终端设备发送第二门限值。
需要说明的是本申请实施例中，测量结果与第二门限值之间的大小关系满足第二预定大小关系时，终端设备2不再向基站2发送上行数据，而是在原先分配给发送上行数据的时频资源上发送预先配置的测量上报格式规定的传输内容。
例如，预先配置的测量上报格式中可以规定终端设备向基站上报的内容，如干扰测量结果、信道状态信息(channel state information，CSI)报告等其他需要终端设备上报的内容。还可以规定终端设备向基站上报的内容的长度、以及发射功率等信息。
可选的，在本申请实施例中测量上报格式可以是基站指示给终端设备，也可以是预定义在终端设备和基站中。具体的，当测量上报格式为基站指示给终端设备时，基站向终端设备发送指示信息，若指示信息用于指示第一测量上报格式，则终端设备根据第一测量上报格式向基站发送传输内容，需要说明的是，该指示信息可以携带在配置信息中发送给终端设备，也可以在其他信令消息中发送给终端设备，本申请实施例对此不进行限定。
需要说明的是，在本申请实施例中配置信息可以为无线资源控制(radio resource control，RRC)信令，或者其它配置信令消息，对此本申请实施例不做限定。
此外，在本申请实施例中，终端设备2还可以根据资源块的大小，从预先配置M个测量上报格式中选择一个第二测量上报格式，其中M为正整数，然后终端设备2向基站2发送第二测量上报格式规定的传输内容。通过该种方法，终端设备可以根据资源块大小进行适配， 选择最多能够容纳的测量上报格式进行报告。
示例的，假设M取值为4，M个测量上报格式如表5所示。
