相关申请的交叉引用
本申请主张在2017年11月15日在中国提交的中国专利申请No.201711133014.0的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及一种终端能力的指示方法及终端。
在无线通信网络中,网络侧根据终端的能力决定如何调度该终端,所以终端需要在接入网络时上报自身的终端能力。终端能力在载波聚合下引入了带宽组合(Band Combination,BC)的概念,即终端是按照BC上报的。在长期演进(Long Term Evolution,LTE)与新空口(New radio,NR)的双连接(即EN-DC)中,目前已经确定要按照BC来上报是否需要支持单发(1UL Tx)的能力指示,但是同时引入了信道组合(Channel Combination,CC)的概念,即一个带宽(band)内多个信道(channel),是比带宽更细的粒度。图1表示终端能力上报架构图,如图1所示,终端的能力上报的粒度由大到小依次为:每个带宽组合(per BC)、每个带宽(per band)、每个下行链路(Down Link,DL)/上行链路(Up Link,UL)、多输入多输出(Multiple Input Multiple Output,MIMO)/带宽种类(bandwidth class)。
在目前的终端能力上报过程中,由于终端是按BC上报给网络侧的,因此对于终端是否必须支持上行双发的指示,也需要和其他的射频参数一起在这个过程中上报给网络侧。
另外,对于根据无线接入网(Radio Access Network,RAN)4定义的各种问题场景,终端还会根据不同的问题场景来上报自己在当前事件下是否必须支持上行双发。
5G终端在配置了上行双连接或多个小区的情况下,可以采用上行双发来提升数据速率等***性能。但是在某些频点或带宽内,由于信号的干扰特性, 使得终端使用上行双发的性能反而因为干扰而下降,严重时,性能还不如使用上行单发的情况。其中的烦扰特性包括交调干扰或协波干扰。
而且在终端的实现过程中,为了实现上行双发,需要更高的成本用于滤波器,从而降低两条上行链路之间或者上下行链路之间的干扰。
由于上行双发带来的干扰问题,5G终端在某些场景或者某些频带内无法做到上行双发。对于终端是否必须支持上行双发的指示,目前只确定了要按照BC来进行上报,但对于复杂(difficult)BC里存在简单(easy)CC的情况,并没有具体的信令涉及终端如何在这种情况下进行上行双发支持情况的上报。

如图2所示,本公开实施例提供一种终端能力的指示方法,应用于终端,包括:
步骤201,多个带宽组合中,按照每个带宽组合,发送终端是否支持上行双发的能力指示信息给网络侧;
具体地,所述能力指示信息包括:终端所支持的带宽组合的第一指示信息、所述带宽组合存在信道组合时,所述信道组合的第二指示信息和指示终端的射频特性的第三指示信息中的至少一项;
其中,所述第一指示信息包括:所述带宽组合的类型信息或所述带宽组 合是否必须支持上行双发;这里需要说明的是,该带宽组合的类型信息指的是简单类型或复杂类型,即带宽组合为简单类型还是复杂类型。
所述第二指示信息包括:所述信道组合的类型信息或所述信道组合是否必须支持上行双发;这里需要说明的是,该信道组合的类型信息指的是简单类型或复杂类型,即信道组合为简单类型还是复杂类型。
所述第三指示信息包括:终端的射频特性是否支持上行双发。
还需要说明的是,本公开中所说的上行双发尤其指上行同时双发。
本公开实施例中,终端按照多个带宽组合中的每个带宽组合,通过将上述的能力指示信息发送给网络侧,保证了网络交互中信息的一致性,保证了通信的可靠性。
首先需要说明的是,当带宽组合为简单类型时,则表明该带宽组合必须支持上行同时双发,而带宽组合为复杂类型时,则表明该带宽组合不一定支持上行同时双发;当信道组合为简单类型时,则表明该信道组合必须支持上行同时双发,而当信道组合为复杂类型时,则表明该信道组合不一定支持上行同时双发。
下面分别从步骤201的不同实现方式,对本公开实施例进行具体说明如下。
一、步骤201的具体实现方式为:根据网络侧对所有频带的部署信息,确定终端是否支持上行双发的能力指示信息;将所述能力指示信息发送给所述网络侧。
1、终端只上报带宽组合的类型
需要说明的是,在此种情况下,该能力指示信息中只包括第一指示信息,即终端可以只向网络侧上报带宽组合(BC)的类型,以告知网络侧该BC为复杂类型的BC还是简单类型的BC。
具体地,终端在接入网络时,需要上报自己的能力,终端根据自己支持的BC是否为复杂类型的BC,多个带宽组合中,按照每个BC(per band combination)上报1bit指示说明该BC是否为复杂类型的BC,或者指示该BC是否必须支持同时上行发送,体现自己对上行双发的支持情况。此1bit指示将和其他能力一起上报给网络侧。
此时对于BC下的CC,可以根据约定(例如,RAN4约定)的方式(如通过公式计算)确定这些CC是否为复杂CC,即在此种情况下,终端隐式指示具体哪些CC为复杂CC。
2、终端同时上报带宽组合的类型和信道组合的类型
在此种情况下,所述能力指示信息同时包括所述第一指示信息和所述第二指示信息,步骤201的具体实现方式为:采用第一预设比特组合,将所述能力指示信息发送给所述网络侧;
其中,所述能力指示信息中的不同指示信息分别采用第一预设比特组合中的不同比特进行指示;或者
所述能力指示信息中的不同指示信息采用第一预设比特组合中的比特进行联合编码指示。
需要说明的是,在所述能力指示信息中包括所述第一指示信息和所述第二指示信息,且所述能力指示信息中的不同指示信息分别采用第一预设比特组合中的不同比特进行指示时,所述第一预设比特组合中的第一个数的比特用于进行所述第一指示信息的指示;所述第一预设比特组合中的第二个数的比特用于进行所述第二指示信息的指示。
通常情况下,为了降低比特开销,该第一预设比特组合优选采用2比特,即分别采用1比特进行第一指示信息的指示,采用另1比特进行第二指示信息的指示。
例如,假设第一比特为1时代表该BC为复杂类型的BC,为0时代表该BC为简单类型的CC,第二比特为1时代表该BC下不存在简单的CC,为0时代表该BC下存在简单类型的CC,则:
11:该BC为复杂类型的BC,其下所有CC都为复杂类型的CC,此时终端在所有CC上都支持上行单发。
10:该BC为复杂类型的BC,其下存在简单类型的CC,此时终端在该BC下的简单类型的CC上必须支持上行双发,具体的CC配置由RAN4确定。
00:该BC为简单类型的BC,此时意味着在该BC下所有CC也都为简单类型,此时终端在该BC下的所有CC上必须支持上行双发。
01:留作扩展,如可以用来表示复杂类型的BC下存在简单类型的CC但 所有CC上都必须支持双发的情况。
当所述第一指示信息和所述第二指示信息采用第一预设比特组合中的比特进行联合编码指示时,将不同的BC通过比特图(Bitmap)来进行比特与复杂类型的BC/复杂类型的CC情况或者是否必须支持上行双发的对应,终端在上报能力时根据自己支持的BC是否为复杂类型的BC/CC或者是否必须支持上行双发时,上报一串比特,网络侧根据bitmap了解终端对于上行双发的支持情况(即是否必须支持上行双发)。
二、步骤201的具体实现方式为:根据网络侧动态配置的用于传输的频带,确定终端是否支持上行双发的能力指示信息;将所述能力指示信息发送给所述网络侧。
具体地,终端进行能力指示信息发送的时机可以为以下两种情况:情况(1),在终端接入网络或接收到网络设备发送的请求时,将所述能力指示信息发送给所述网络设备;情况(2),在获取到网络设备配置的频段信息后,将所述能力指示信息发送给所述网络设备。
1、终端只上报带宽组合的类型
需要说明的是,在此种情况下,该能力指示信息中只包括第一指示信息,即终端可以只向网络侧上报BC的类型,以告知网络侧该BC为复杂类型的BC还是简单类型的BC。
具体地,终端根据网络侧配置的可用于传输的频带,根据RAN4约定的方式(如通过公式计算)确定这些频带组合是否为复杂类型的BC,按照每个BC上报1bit指示该BC为复杂类型的BC或简单类型的BC,或者指示在该BC是否必须支持同时上行发送。
此时对于BC下的CC,可以根据约定(例如,RAN4约定)的方式(如通过公式计算)确定这些CC是否为复杂CC,即在此种情况下,终端隐式指示具体哪些CC为复杂CC。
2、终端同时上报带宽组合的类型和信道组合的类型
在此种情况下,所述能力指示信息同时包括所述第一指示信息和所述第二指示信息,步骤201的具体实现方式为:采用第二预设比特组合,将所述能力指示信息发送给所述网络侧;
其中,所述能力指示信息中的不同指示信息分别采用第二预设比特组合中的不同比特进行指示;或者
所述能力指示信息中的不同指示信息采用第二预设比特组合中的比特进行联合编码指示。
需要说明的是,在所述能力指示信息中包括第一指示信息和第二指示信息,且所述能力指示信息中的不同指示信息分别采用第二预设比特组合中的不同比特进行指示时,所述第二预设比特组合中的第三个数的比特用于进行所述第一指示信息的指示;所述第二预设比特组合中的第四个数的比特用于进行所述第二指示信息的指示。
通常情况下,为了降低比特开销,该第二预设比特组合优选采用2比特,即分别采用1比特进行第一指示信息的指示,采用另1比特进行第二指示信息的指示。
例如,假设第一比特为1时代表该BC为复杂类型的BC,为0时代表该BC为简单类型的CC,第二比特为1时代表该BC下不存在简单的CC,为0时代表该BC下存在简单类型的CC,则:
11:该BC为复杂类型的BC,其下所有CC都为复杂类型的CC,此时终端在所有CC上都支持上行单发。
10:该BC为复杂类型的BC,其下存在简单类型的CC,此时终端在该BC下的简单类型的CC上必须支持上行双发,具体的CC配置由RAN4确定。
00:该BC为简单类型的BC,此时意味着在该BC下所有CC也都为简单,此时终端在该BC下的所有CC上必须支持上行双发。
还需要说明的是,在此种情况下,在所述第一指示信息指示所述带宽组合为复杂类型,且第二指示信息指示存在简单类型的信道组合时,还可以进一步进行具体哪些CC为简单类型的CC指示,具体地,实现方式为:所述能力指示信息中还包括:用于进行简单类型的信道组合的确定的第三指示信息。
例如,当具体哪些CC为简单类型的CC是通过RAN4支持的确定简单类型的CC的计算方法(例如,RAN4支持2种确定简单类型的CC的计算方法)决定时,该第三指示信息可以为所采用的计算方法的类型。
通常该第三指示信息与第一指示信息和第二指示信息一同均采用第二预 设比特组合进行指示。
例如,假设第一比特为1时代表该BC为复杂类型的BC,为0时代表该BC为简单类型的CC,第二比特为1时代表该BC下不存在简单的CC,为0时代表该BC下存在简单的CC,则:
11:该BC为复杂类型的BC,其下所有CC都为复杂CC,此时终端在所有CC上都支持上行单发。
00:该BC为简单类型的BC,此时意味着在该BC下所有CC也都为简单类型,此时终端在该BC下的所有CC上必须支持上行双发。
10/01:该BC为复杂类型的BC,其下存在简单类型的CC,具体如何确定简单类型的CC由RAN4决定。如果RAN4支持两种确定简单类型的CC的计算方法,则可以通过这两个bit值来区分两种不同的计算方法。
当所述第一指示信息和所述第二指示信息采用第二预设比特组合中的比特进行联合编码指示时,将不同的BC通过Bitmap来进行比特与复杂类型的BC/复杂CC情况或者是否必须支持上行双发的对应,终端在上报能力时根据自己支持的BC是否为复杂类型的BC/CC或者是否必须支持上行双发时,上报一串比特,网络侧根据bitmap了解终端对于上行双发的支持情况(即是否必须支持上行双发)。
3、终端同时上报带宽组合的类型和射频特性
在此种情况下,所述能力指示信息同时包括所述第一指示信息和所述第三指示信息,步骤201的具体实现方式为:采用第二预设比特组合,将所述能力指示信息发送给所述网络侧;
其中,所述能力指示信息中的不同指示信息分别采用第二预设比特组合中的不同比特进行指示;或者
所述能力指示信息中的不同指示信息采用第二预设比特组合中的比特进行联合编码指示。
需要说明的是,在所述能力指示信息中包括所述第一指示信息和所述第三指示信息,且所述能力指示信息中的不同指示信息分别采用第二预设比特组合中的不同比特进行指示时,所述第二预设比特组合中的第五个数的比特用于进行所述第一指示信息的指示;所述第二预设比特组合中的第六个数的 比特用于进行所述第三指示信息的指示。
通常情况下,为了降低比特开销,该第二预设比特组合优选采用2比特,即分别采用1比特进行第一指示信息的指示,采用另1比特进行第三指示信息的指示。
例如,假设第一比特为1时代表该BC为复杂类型的BC,为0时代表该BC为简单类型的CC,第二比特为1时代表终端自己的射频特性不支持上行双发,为0时代表终端自己的射频(Radio Frequency,RF)特性支持上行双发,则:
00:该BC为简单BC,在该BC下所有CC也都为简单,终端自身的RF特性也支持上行双发,则此时终端在该BC下所有CC都支持上行双发;
01:该BC为简单BC,此时意味着在该BC下所有CC也都为简单,此时终端在该BC下的所有CC上必须支持上行双发。
10:该BC为复杂类型的BC,终端自身射频特性支持上行双发,则在该复杂类型的BC下的简单类型的CC上必须支持上行双发,具体的CC配置由RAN4决定。
11:该BC为复杂类型的CC,且终端自身射频特性不支持上行双发,此时终端在该BC下均不支持上行双发
当所述第一指示信息和所述第三指示信息采用第二预设比特组合中的比特进行联合编码指示时,将不同的BC通过Bitmap来进行比特与复杂类型的BC情况和射频特性是否必须支持上行双发的对应,终端在上报能力时根据自己支持的BC是否为复杂类型的BC和是否必须支持上行双发时,上报一串比特,网络侧根据bitmap了解终端对于上行双发的支持情况(即是否必须支持上行双发)。
需要说明的是,本公开实施例中所说的多个带宽组合指的是终端所支持的全部带宽组合或部分带宽组合;例如,针对步骤201的不同实现方式,第一种实现方式中所说的多个带宽组合为所述终端所支持的全部带宽组合,第二种实现方式中所说的多个带宽组合可以为所述终端支持的全部带宽组合中的一部分,所属领域技术人员可以理解,本公开的实施例不以此为限制。
本公开实施例,终端通过将所支持的带宽组合以及带宽组合中的信道组 合的类型信息上报给网络,保证了网络交互中信息的一致性,以此完善了5G通信流程,保证了通信的可靠性。
需要说明的是,本实施例中终端主要是与网络侧的网络设备进行交互,该网络设备可以是全球移动通讯(Global System of Mobile communication,简称GSM)或码分多址(Code Division Multiple Access,简称CDMA)中的基站(Base Transceiver Station,简称BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,简称WCDMA)中的基站(NodeB,简称NB),还可以是LTE中的演进型基站(Evolutional Node B,简称eNB或eNodeB),或者中继站或接入点,或者未来5G网络中的基站等,在此并不限定。
