Description

上行信道资源的指示及确定方法、基站、终端、介质
本申请要求于2018年08月08日提交中国专利局、申请号为201810899832.X、发明名称为“上行信道资源的指示及确定方法、基站、终端、介质”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
本发明实施例涉及通信领域，尤其涉及一种上行信道资源的指示及确定方法、基站、终端、介质。
背景技术
为了公平有效地利用非授权频谱，提高新无线(New Radio，NR)***的数据传输速率，3GPP标准组织支持在非授权频谱上部署NR网络。NR网络对非授权频谱的使用有三种方式：1、非授权频谱的NR小区为主小区，用户终端(User Equipment，UE)直接接入非授权频谱的NR小区；2、UE通过长期演进***(Long Term Evolution，LTE)小区接入非授权频谱的NR小区；3、UE通过NR小区接入非授权频谱的NR小区。对于方式2和方式3，授权频谱和非授权频谱通过类似于载波聚合的方式结合使用，即一个终端、演进型基站(Evolved Node B，gNB)可能同时工作在授权频谱和非授权频谱上。也称为NR-U(new RAT unlicense)技术。
在LTE授权频谱辅助接入(LAA，Licensed Assisted Access)技术中，物理上行共享信道(Physical Uplink Share Channel，PUSCH)传输采用交错集(interlace)的方式，每个interlace为资源分配的基本单 元，20MHz/10MHz的interlace包含频域上均匀分布的10个物理资源块(Physical Resource Block，PRB)，如interlace 0由资源块(Resource Block，RB)索引为0、10、20、...、90组成。其中RB0～RB9构成交错资源组(cluster)0，依次类推RB10～RB19构成交错资源组(cluster)1……，每个交错资源组中均包含10个RB，分别属于不同的交错集(interlace)。
对于NR***，LAA可采用先听后说(Listen-Before-Talk，LBT)机制实现非授权频谱中不同运营商的LAA及其它***的共存。在LBT过程中，对于非授权频谱，在传输数据前需要先通空闲信道评估(Clear Channel Assessment，CCA)判断当前信道是否可用。
在现有的NR***中，一个载波或者带宽部分(Bandwidth Part，BWP)支持的带宽范围较大，例如，有可能大于20MHz，也有可能小于20MHz。现有的上行资源指示以全载波或者全BWP为单位，导致资源利用率低，NR网络性能较差。

具体实施方式
在现有的NR***中，一个载波或者BWP支持的带宽范围较大，例如，有可能大于20MHz，也有可能小于20MHz。现有的上行资源指示以全载波或者全BWP为单位，导致资源利用率低，NR网络性能较差。
本发明实施例首先通过高层信令向UE指示当前载波包含的N个子带对应的频域资源信息，然后再通过下行控制信息向UE指示用于传输上行数据的一个或者多个子带，使得UE可以基于用于传输上行数据的子带对应的频域资源信息，传输上行数据。由于可以以子带为单位指示上行资源，故可以提高NR网络的资源利用率和性能。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参见图1，本发明实施例提供了一种上行信道资源的指示方法，可以包括如下步骤：
步骤S101，通过高层信令向UE指示当前载波包含的N个子带 对应的频域资源信息，其中N>1。
在具体实施中，由于现有的NR***以全载波或者全BWP为单位指示上行资源，导致资源利用率低，NR网络性能较差，故本发明实施例考虑以子带为单位指示上行资源。
在具体实施中，为了以子带为单位指示上行资源，首先需要通过高层信令向UE指示子带的配置信息，即子带对应的频域资源信息。
在具体实施中，所述子带对应的带宽小于等于当前载波的带宽或者当前BWP(即当前激活BWP)的带宽。
在实际应用中，所述子带的带宽可以为20MHz，也可以为40MHz，还可以为其他值，子带的带宽并不对本发明的保护范围造成限制。
在具体实施中，所述高层信令可以为小区级的高层信令，即面向每个小区向UE指示当前载波包含的N个子带对应的频域资源信息。
在具体实施中，所述N个子带对应的频域资源信息包括：N-1个公共资源块(Common Resource Block，CRB)索引；所述N-1个CRB索引用于指示N个子带的起始CRB。即从载波带宽的第一个可用的CRB索引起到第一个CRB索引-1止为第一个子带；从第一个CRB索引起到第二个CRB索引止为第二个子带，…，从N-1个CRB索引起到载波***带宽的最高的CRB索引止为第N个子带。
例如，N＝2，即当前载波包含2个子带，使用1个CRB索引指示2个子带的起始CRB。CRB索引为x表示：从载波带宽的第一个可用的CRB索引(例如，CRB6)起至x-1止为第一个子带；从x到载波***带宽的最高CRB索引止为第2个子带。
步骤S102，通过下行控制信息向所述UE指示用于传输上行数据的一个或者多个子带，使得所述UE基于所述用于传输上行数据的子带对应的频域资源信息，使用所述用于传输上行数据的子带对应的频域资源传输上行数据。
在具体实施中，可以通过下行控制信息(Downlink Control Information，DCI)调度一个或者多个子带，用于上行传输。
在本发明一实施例中，通过下行控制信息中的比特图(bitmap)，向UE指示用于传输上行数据的一个或者多个子带的索引。
例如，下行调度指示上行共享信道的接入方式为短LBT方式，当前载波包含N个子带，当前BWP包含M个子带，则DCI中包含M个比特长度的bitmap，用于指示哪些子带可用于传输上行数据。其中，每个子带内的频域资源指示信息相同。
在本发明一实施例中，通过下行控制信息中的资源指示值(Resource Indication Value，RIV)向UE指示传输上行数据的一个或者多个子带的索引。
在具体实施中，可以通过所述资源指示值中的X个比特指示传输上行数据的一个或者多个子带的索引；其中
Figure PCTCN2019092980-appb-000005
M为当前BWP包含的子带的总个数，ceil()为上舍入运算符。
例如，DCI指示上行共享信道的接入方式为短LBT方式，当前载波包含N个子带，当前BWP包含M个子带，则DCI中包含X个比特长度的RIV字段，用于指示哪些子带可用于传输上行数据。
与采用Bitmap向UE指示用于传输上行数据的一个或者多个子带的索引相比，采用RIV向UE指示传输上行数据的一个或者多个子带的索引，只能指示连续的子带，且其中每个子带内的频域资源指示信息相同，在实际应用中可以根据需求选择不同的实现方式。
在具体实施中，还可以通过DCI中的频域资源分配字段指示分配了哪些interlace和哪些cluster，使得UE基于cluster的起始位置和长度，确定传输上行数据的一个或者多个子带。
为了使本发明技术人员更好地理解和实施本发明，本发明实施例提供了一种interlace、cluster和子带的关系示意图，如图2所示。
参见图2，当前BWP对应的带宽为40MHz，划分为子带1和子带2，每个子带对应的带宽分别为20MHz。每个子带对应10个cluster，分别为cluster0至cluster9。每个cluster中包含10个RB，分别为RB0～RB9，且10个RB分别属于不同的交错集interlace。例如，interlace0由每个cluster中的索引为0的RB组成。
在具体实施中，可以通过下行控制信息中的资源指示值向UE指示传输上行数据的交错资源组的起始位置和长度，使得UE基于交错资源组的起始位置和长度，确定传输上行数据的一个或者多个子带。
在本发明一实施例中，所述通过下行控制信息中的资源指示值向UE指示传输上行数据的交错资源组的起始位置和长度包括：通过所述资源指示值中的Y个比特向UE指示传输上行数据的交错资源组的起始位置和长度；其中
Figure PCTCN2019092980-appb-000006
K为当前BWP包含的交错资源组的总个数，ceil()为上舍入运算符。
需要特别说明的是，对于特殊场景，当基站需要向UE指示用于传输上行数据的一个或者多个子带为：当前BWP内的所有子带时，下行控制信息中可以不携带子带信息，也属于本发明实施例的保护范围。
应用上述方案，首先通过高层信令向UE指示当前载波包含的N个子带对应的频域资源信息，然后再通过下行控制信息向UE指示用于传输上行数据的一个或者多个子带，使得UE可以基于用于传输上行数据的子带对应的频域资源信息，传输上行数据。由于可以以子带为单位指示上行资源，故可以提高NR网络的资源利用率和性能。
为使本领域技术人员更好的理解和实施本发明，本发明实施例还提供了一种上行信道资源的确定方法，如图9所示。
参见图9，所述上行信道资源的确定方法可以包括如下步骤：
步骤S901，接收基站发送的高层信令，所述高层信令包括当前载波包含的N个子带对应的频域资源信息，其中N>1。
在具体实施中，基站可以采用图1对应的实施例中的方法，指示当前载波包含的N个子带对应的频域资源信息，此处不再赘述。
步骤S902，接收基站发送的下行控制信息，所述下行控制信息包括用于传输上行数据的一个或者多个子带，并基于用于传输上行数据的子带对应的频域资源信息，使用所述用于传输上行数据的子带对应的频域资源传输上行数据。
在具体实施中，基站可以采用图1对应的实施例中的方法，指示用于传输上行数据的一个或者多个子带，此处不再赘述。
在具体实施中，所述N个子带对应的频域资源信息可以包括：N-1个CRB索引；所述N-1个CRB索引用于指示N个子带的起始CRB。
在具体实施中，可以通过下行调度指示上行链路物理共享信道(Physical Uplink Share Channel，PUSCH)信道的接入方式，当PUSCH信道的接入方式为短LBT时，所述用于传输上行数据的所有子带对应一个PUSCH；当PUSCH信道的接入方式为长LBT时，所述用于传输上行数据的每个子带对应一个PUSCH。
在本发明一实施例中，当下行调度指示PUSCH信道的接入方式为短LBT时，所述用于传输上行数据的所有子带对应一个PUSCH；当下行调度指示PUSCH信道的接入方式为长LBT时，所述用于传输上行数据的每个子带对应一个PUSCH。
在具体实施中，当PUSCH信道的接入方式为长LBT时，所述使用所述用于传输上行数据的子带对应的频域资源传输上行数据可以包括：对所述下行控制信息指示的所述一个或者多个子带执行LBT检测；基于LBT检测结果，选取LBT检测成功的一个子带作为候选子带；使用候选子带对应的频域资源传输上行数据。
在具体实施中，可以基于LBT检测结果，在LBT检测成功的多个子带中任意选择一个子带作为候选子带。
在本发明一实施例中，所述选取LBT检测成功的一个子带作为候选子带包括：在LBT检测成功的子带之中选取索引值最低或者索引值最高的子带作为候选子带。
在具体实施中，当只选择LBT检测成功的一个子带传输上行数据时，还需要确定第i个时隙对应的PUSCH使用的HARQ ID。
在本发明一实施中，所述使用候选子带对应的频域资源传输上行数据还包括：基于公式(1)确定第i个时隙对应的PUSCH使用的HARQ ID：
mod(n HARQ_ID+i,N HARQ)     (1)
其中：i为下行控制信息中调度PUSCH的时隙对应的相对索引，n HARQ_ID为下行控制信息中指示的起始HARQ ID，N HARQ为HARQ ID的总个数，mod()为取余数运算符。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提供了一种HARQ ID的示意图，如图3所示。
参见图3，当前BWP包含两个子带，DCI调度了4个时隙，起始HARQ ID为0，只有一个子带(子带2)LBT检测成功，此时UE选择子带2传输PUSCH，且基于公式(1)确定时隙slot0～slot3使用的HARQ ID分别为0、1、2、3。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提供了另一种HARQ ID的示意图，如图4所示。
参见图4，当前BWP包含两个子带，即子带1和子带2，DCI调度了4个时隙，起始HARQ ID为0，两个子带均LBT检测成功，此时UE选择索引值低的子带1传输PUSCH，且基于公式(1)确定时隙slot0～slot3使用的HARQ ID分别为0、1、2、3。
在具体实施中，可以基于LBT检测结果，选择LBT检测成功的所有子带传输上行数据。
在本发明一实施例中，当PUSCH信道的接入方式为长LBT时，所述使用所述用于传输上行数据的子带对应的频域资源传输上行数据包括：对所述下行控制信息指示的所述一个或者多个子带执行LBT检测；基于LBT检测结果，使用LBT检测成功的所有子带对应的频域资源传输上行数据。
在具体实施中，当使用LBT检测成功的所有子带对应的频域资源传输上行数据时，对应每个时隙，所述多个子带可以对应相同的PUSCH，也可以对应不同的PUSCH。
在具体实施中，当下行调度指示PUSCH的信道接入方式为长LBT方式，且DCI中的频域资源分配字段指示可以调度一个或多个子带内的频域资源时，UE可以根据LBT的结果，在基站通过DCI指示的子带中选择LBT成功的所有子带传输PUSCH，且每个子带内传输的PUSCH相同。
在本发明一实施例中，当所述多个子带对应相同的PUSCH时，所述使用LBT检测成功的所有子带对应的频域资源传输上行数据还包括：基于公式(1)确定第i个时隙对应的PUSCH使用的HARQ ID。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提供了又一种HARQ ID的示意图，如图5所示。
参见图5，当前BWP包含两个子带，DCI调度了4个时隙，起始HARQ ID为0，只有一个子带(子带2)LBT检测成功，此时UE选择子带2传输PUSCH，且基于公式(1)确定时隙slot0～slot3使用的HARQ ID分别为0、1、2、3。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提供了再一种HARQ ID的示意图，如图6所示。
参见图6，当前BWP包含两个子带，即子带1和子带2，DCI 调度了4个时隙，起始HARQ ID为0，两个子带均LBT检测成功，此时UE选择子带1和子带2传输相同的PUSCH，且对于子带1和子带2，基于公式(1)确定时隙slot0～slot3使用的HARQ ID分别为0、1、2、3。
在具体实施中，当所述一个或者多个子带对应不同的PUSCH时，每个PUSCH可以使用不同的HARQ-ID版本和/或不同的冗余版本(Redundancy Version，RV)版本。
在具体实施中，当下行调度指示PUSCH的信道接入方式为长LBT方式，且DCI中的频域资源分配字段指示可以调度一个或多个子带内的频域资源时，UE可以根据LBT的结果，在DCI指示的子带中选择LBT成功的所有子带传输PUSCH，此时每个子带都对应一个独立的PUSCH。
在具体实施中，当UE成功接入多个子带，每个成功的子带上都只允许传一个PUSCH，且多个子带上传输的PUSCH的调制与编码策略(Modulation and Coding Scheme，MCS)相同，频域interlace也相同。不同之处在于每个子带内传输的PUSCH使用不同的HARQ-ID和/或不同的RV版本。
在本发明一实施例中，当所述多个子带对应不同的PUSCH时，所述使用LBT检测成功的所有子带对应的频域资源传输上行数据还包括：基于公式(2)确定第j个子带对应的PUSCH使用的HARQ ID：
mod(n HARQ_ID+i×M+j,N HARQ)     (2)
其中：M为当前BWP包含的子带的总个数，j为子带索引，且j为0表示频域位置最低的子带。i为下行控制信息中调度PUSCH的时隙(slot)对应的相对索引，例如，调度S＝4个时隙传输，则i＝(0，1，…，S-1)。n HARQ_ID为下行控制信息中指示的起始HARQ ID，N HARQ为HARQ ID的总个数，mod()为取余数运算符。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提 供了另一种HARQ ID的示意图，如图7所示。
参见图7，当前BWP包含两个子带，DCI调度了4个时隙，起始HARQ ID为0，只有一个子带(子带2)LBT检测成功，此时UE选择子带2传输PUSCH，且基于公式(2)确定时隙slot0～slot3使用的HARQ ID分别为1、3、5、7。
为使本领域技术人员更好地理解和实施本发明，本发明实施例提供了又一种HARQ ID的示意图，如图8所示。
参见图8，当前BWP包含两个子带，即子带1和子带2，DCI调度了4个时隙，起始HARQ ID为0，两个子带均LBT检测成功，此时UE选择子带1和子带2传输PUSCH，且对于子带2，基于公式(2)确定时隙slot0～slot3使用的HARQ ID分别为1、3、5、7；对于子带1，基于公式(2)确定时隙slot0～slot3使用的HARQ ID分别为0、2、4、6。
应用上述方案，首先接收基站发送的高层信令，然后接收基站发送的下行控制信息，可以基于用于传输上行数据的子带对应的频域资源信息，使用用于传输上行数据的子带的频域资源传输上行数据。由于可以以子带为单位指示上行资源，故可以提高NR网络的资源利用率和性能。
为使本领域技术人员更好的理解和实施本发明，本发明实施例还提供了一种能够实现上述上行信道资源的指示方法的基站，如图10所示。
