Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及无线通信方法、终端设备和网络设备。
背景技术
当终端工作于载波聚合(Carrier Aggregation，CA)、E-UTRA和NR双连接(E-UTRA-NR Dual Connectivity，EN-DC)、双连接(Dual Connection，DC)等频段组合下时，终端在多个载波上的总发射功率将不能超过Pcmax值；其中，Pcmax是终端可配置的最大发射功率，对于频段组合来说意味着所有载波上的总发射功率不能超过该值。
当一个载波上的发射功率增加时，意味着其它载波可用的发射功率将减少。换言之，当某一个载波占用了所有的发射功率时，其它载波上将没有发射功率可使用。例如，在CA等频段组合下，假设终端需要在主载波(Primary Cell Component，PCC)和辅载波(Secondary Cell Component，SCC)上同时进行发射，但主载波占用了大部分的功率，导致辅载波上的发射功率过小以致难以维持上行链路，将导致SCC链路断开的情况，也即只有PCC在工作。相比之下，如果PCC和SCC都能保持链路并进行通信，数据传输的整体的吞吐量将优于PCC独自发射的情况。
此外，当前新空口(New Radio，NR)在频段组合下，会将功率首先供更高优先级的载波使用，之后才将剩余功率分配给低优先级载波使用。因此，当高优先级载波占据了大部分甚至所有功率后，低优先级载波将会断掉连接。例如，在CA等频段组合下，PCC的优先级可能会低于SCC的优先级，然而若PCC上的发射功率无法保持链路的正常连接，则将导致PCC和SCC都掉线，降低了数据传输的可靠性。
因此，本领域亟需一种能够提升数据传输的吞吐量和可靠性的无线通信方法。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
当终端工作于载波聚合(Carrier Aggregation，CA)、E-UTRA和NR双连接(E-UTRA-NR Dual Connectivity，EN-DC)、双连接(Dual Connection，DC)等频段组合下时，终端在多个载波上的总发射功率将不能超过Pcmax值；其中，Pcmax是终端可配置的最大发射功率，对于频段组合来说意味着 所有载波上的总发射功率不能超过该值。
当一个载波上的发射功率增加时，意味着其它载波可用的发射功率将减少。换言之，当某一个载波占用了所有的发射功率时，其它载波上将没有发射功率可使用。
图2是本申请实施例提供的CA场景下的终端设备的发射功率的示意图。
如图2所示，在CA等频段组合下，假设终端需要在主载波(Primary Cell Component，PCC)和辅载波(Secondary Cell Component，SCC)上同时进行发射，但主载波占用了大部分的功率，导致辅载波上的发射功率过小以致难以维持上行链路，将导致SCC链路断开的情况，也即只有PCC在工作。这种情况在网络中比较常见，也即网络设备会根据载波上的信号质量来配置资源块(Resource Block，RB)资源以及调度调制与编码策略(Modulation and Coding Scheme，MCS)。比如，当终端设备处于小区中心时，PCC的信号质量比较好时，网络设备将分配更多的RB同时调度更高的MCS，使得终端设备发射很高的功率。而此时，SCC上面由于其优先级低于PCC，仅能使用剩余的功率，而导致链路难以维持并发生SCC链路失败的情况。
相比之下，如果PCC和SCC都能保持链路并进行通信，数据传输的整体的吞吐量将优于PCC独自发射的情况。
此外，多个载波间的相对优先级受多个因素的影响，包括载波上发射的信道类型(例如PUSCH和PUCCH优先级要高于SRS等)、信道承载的业务内容(例如PUSCH和PUCCH的相对优先级跟其上面承载的是控制信息还是业务信息等有关)、网络设备直接指示的优先级(例如网络设备通过信令指示载波是高优先级还是低优先级)等。因此，当SCC具有更高优先级时，终端设备将大部分功率分给SCC发射，则将导致PCC掉线，使得终端设备发生从网络断开的问题，因为PCC如果掉线则SCC也将掉线。
也即是说，当前新空口(New Radio，NR)在频段组合下，会将功率首先供更高优先级的载波使用，之后才将剩余功率分配给低优先级载波使用。因此，当高优先级载波占据了大部分甚至所有功率后，低优先级载波将会断掉连接。例如，在CA等频段组合下，PCC的优先级可能会低于SCC的优先级，然而若PCC上的发射功率无法保持链路的正常连接，则将导致PCC和SCC都掉线，降低了数据传输的可靠性。
基于此，本申请实施例提供了一种无线通信方法、终端设备和通信设备，能够提升数据传输的吞吐量和可靠性。

下面结合具体实施例对本申请的方案进行说明。
实施例1：
本实施例中，终端设备可基于所述至少一个第一载波分别对应的至少一个第一门限值，确定所述多个载波上的发射功率。其中，所述至少一个第一载波包括所述多个载波中的高优先级的载波。也即是说，网络设备对高优先级载波配置一个绝对功率限制或相对功率限值，使得高优先级载波不会占用太多发射功率而导致低优先级载波上的发射功率不够用情况发生。例如，网络设备初始配置的多个载波具有确定的优先级高低顺序，示例性地，在EN-DC组合中，LTE载波作为主载波具有比NR辅载波更高的优先级。
网络设备给高优先级载波分别配置最大发射功率限值Pow_cc，所述Pow_cc可以是绝对功率限值，也可以是相对功率限值。
绝对功率限值指的是载波所能够发射的最大发射功率值。比如对于一个频段组合下终端设备而言，其总体最大发射功率为26dBm，则可以选择配置主载波上的绝对功率限值Pow_cc为23dBm，也即，至少可以剩余23dBm的发射功率供辅载波发射使用。相对功率限值指的是该载波所能发射的最大发射功率相比终端多载波总体最大发射功率的回退值，如{1dB，2dB，3dB，4dB，5dB}。比如，对于一个频段组合下终端设备而言，其总体最大发射功率为26dBm，则可以选择配置主载波上的相对功率限值Pow_cc为3dB，则主载波所能发射的最大功率为26dBm-3dB＝23dBm。也即是说，至少可以剩余26dBm-23dBm＝23dBm的发射功率供辅载波发射使用。
具体实现中，网络设备配置的Pow_cc可以是网络设备通过RRC信令给终端配置载波时一并将所述Pow_cc配置给终端设备，也可以是通过RRC信令将所述Pow_cc单独配置给终端设备。
换言之，网络配置的上述Pow_cc的使用方式可以包括下面两种方式：
方式1：
可以是配置载波及Pow_cc后，当载波激活时所述Pow_cc也一并生效，当载波去激活时所述Pow_cc也一并失效。
方式2：
可以是配置载波及所述Pow_cc后，当载波激活时所述Pow_cc不会即时生效，而是网络设备可以通过MAC信令或物理层DCI指令等来激活或去激活所述Pow_cc；当载波去激活时所述Pow_cc也一并失效。这种方式包括了限值配置和所述Pow_cc激活与去激活两个步骤。
相应的，终端设备收到网络设备配置的所述Pow_cc后，在实际功率发射时将基于所述Pow_cc进行发射功率的控制，确保高优先级载波不超过所述Pow_cc。
实施例2：
本实施例中，终端设备可基于所述至少一个第一载波分别对应的至少一个第一门限值，确定所述多 个载波上的发射功率。其中，所述至少一个第一载波包括所述多个载波中的部分载波或全部载波。也即是说，网络初始配置的多个载波没有确定的优先级高低顺序，如CA组合中载波间的优先级顺序跟某个时刻载波上承载的信道及业务类型等有关，也跟网络设备直接指示的高低优先级有关。
由于网络设备无法预知在某个时刻载波间的优先级相对关系，因此，网络设备需要给每个载波或部分载波分别配置最大发射功率限值Pow_cc，所述Pow_cc可以是绝对功率限值，也可以是相对功率限值。
绝对功率限值指的是载波所能够发射的最大发射功率值。比如对于一个频段组合下终端设备而言，其总体最大发射功率为26dBm，则可以选择配置主载波上的绝对功率限值Pow_cc为23dBm，也即，至少可以剩余23dBm的发射功率供辅载波发射使用。相对功率限值指的是该载波所能发射的最大发射功率相比终端多载波总体最大发射功率的回退值，如{1dB，2dB，3dB，4dB，5dB}。比如，对于一个频段组合下终端设备而言，其总体最大发射功率为26dBm，则可以选择配置主载波上的相对功率限值Pow_cc为3dB，则主载波所能发射的最大功率为26dBm-3dB＝23dBm。也即是说，至少可以剩余26dBm-23dBm＝23dBm的发射功率供辅载波发射使用。
具体实现中，网络设备配置的Pow_cc可以是网络设备通过RRC信令给终端配置载波时一并将所述Pow_cc配置给终端设备，也可以是通过RRC信令将所述Pow_cc单独配置给终端设备。
换言之，网络配置的上述Pow_cc的使用方式可以包括下面两种方式：
方式1：
可以是配置载波及Pow_cc后，当载波激活时所述Pow_cc也一并生效，当载波去激活时所述Pow_cc也一并失效。
方式2：
可以是配置载波及所述Pow_cc后，当载波激活时所述Pow_cc不会即时生效，而是网络设备可以通过MAC信令或物理层DCI指令等来激活或去激活所述Pow_cc；当载波去激活时所述Pow_cc也一并失效。这种方式包括了限值配置和所述Pow_cc激活与去激活两个步骤。
例如，网络设备激活某个载波上的Pow_cc，可以基于该载波在某个时刻的优先级顺序来决定。网络设备可选择激活当前时刻高优先级载波上的Pow_cc；当在下一时刻该载波变为低优先级时，网络设备可选择去激活该载波上的Pow_cc。当然，网络设备也可以在激活或去激活高优先级载波上的Pow_cc时，同时激活或去激活低优先级载波上的Pow_cc。
相应的，终端设备收到网络设备配置的所述Pow_cc后，在实际功率发射时将基于激活的所述Pow_cc进行发射功率的控制，确保高优先级载波不超过所述Pow_cc。
实施例3：
本实施例中，网络设备配置一个适用于小区内所有多载波发射终端的最大发射功率限值Pow_cell，所述Pow_cell可以为绝对功率限值也可以为相对功率限值，不论载波间的优先级如何，所有载波在小区内发射均不能超过Pow_cell。Pow_cell的使用可以如Pow_cc那样包括两种方式，即配置后即时生效，或配置后需要激活才能生效。
示例性地，终端设备的最大发射功率为26dBm，则当网络设备配置了Pow_cell时：如Pow_cell为绝对功率限值，则终端设备不论在哪个多载波上发射功率均不能超过Pow_cell；如Pow_cell为相对功率限值，则终端设备不论在哪个多载波上发射均不能超过26dBm-Pow_cell。
本实施例中，网络设备不需要针对小区内所有终端设备上的多载波分别配置发射功率限值，能够最大限度的降低复杂度。进一步的，可以将Pow_cell和Pow_cc结合使用，也即当网络设备同时配置了Pow_cell和Pow_cc时，终端设备可以根据Pow_cc进行最大发射功率的控制，或者根据Pow_cell和Pow_cc中的最小值进行最大发射功率的控制，由此，可以实现在降低复杂度的同时能够保持一定的灵活性。
实施例3：
本实施例中，终端设备可以自主的发射功率控制，即所述终端设备可以自主确定某个载波上的发射功率是否过低，如基于空间传播损耗是否大于一定门限时，终端设备可自主的调整载波间的发射功率分配。
当上行传播损耗高于一定门限时，终端设备应保证PCC的发射功率，并将剩余功率分配给SCC使用，如多个辅载波中有优先级更高的载波则优先保证该载波的发射功率需求。
当上行传播损耗低于一定门限时，终端设备位于非小区边缘位置，此时，终端设备应保持PCC的最大可用发射功率和SCC的最大可用发射功率相同，或者所述终端设备应保持PCC的最大可用功率密度和SCC的最大可用功率密度相同，或者所述终端设备应保持PCC的最大可用发射功率和PCC的中心工作频率成正比，或者所述终端设备应保持SCC的最大可用发射功率跟SCC的中心工作频率成正比， 或者所述终端设备应满足以下关系：
M P/Ms＝F P/F S；
其中，M P为所述主载波上的最大可用功率或最大可用功率密度；Ms为所述辅载波上的最大可用功率或最大可用功率密度；F P为所述主载波的中心工作频率；F S为所述辅载波的中心工作频率。
可选的，所述一定门限可以为网络设备配置的值，也可以为终端设备自主决定的值。
本实施例中，通过自主确定某个载波上的发射功率是否过低的方式，终端设备能够动态的按照业务需求进行发射功率的调整。
实施例4：
本实施例中，网络设备指示终端设备在某个载波上的发射功率过低时，可触发终端设备调整载波间的发射功率分配。
具体而言，网络设备接收终端设备的多载波发射信号，并测量得到各载波上的接收信号质量(比如强度或信噪比SINR等)。当某载波上的接收信号质量低于一定门限时，所述网络设备可通过RRC或MAC CE等向终端设备发送所述某载波功率过低的指示信息。
相应的，终端设备收到功率过低指示信息后，进一步确定所述某载波的功率优先级，并进行发送功率调整：当高优先级载波或主载波收到功率过低指示信息后，终端设备应增加该载波的发射功率，以避免链路断开；当低优先级载波(非主载波)收到功率过低指示信息后，终端设备应在确保高优先级载波和主载波不断开链路的情况下适当提高低优先级载波功率。
本实施例中，通过网络设备指示的方式，终端设备能够动态的按照业务需求进行发射功率的调整。
基于以上方案，本申请提供了一种调整终端设备在多载波上发射功率的方法，以规避终端设备载波掉线的问题。在一种实现方式中，网络设备可以基于载波优先级，配置高优先级载波上的第一门限值，从而给低优先级载波或主载波预留功率。在另一种实现方式中，网络设备也可以配置适用于小区内所有多载波发射终端设备的第二门限值，也即不论载波间的优先级如何，所有载波在小区内发射均不能超过所述第二门限值。当然，终端设备自主确定某个载波上的发射功率是否过低时(如基于空间传播损耗大于一定门限)或者通过网络设备指示终端设备在某个载波上的发射功率过低时，终端设备调整载波间的发射功率分配。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于上述实施方式中的具体细节，在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，这些简单变型均属于本申请的保护范围。例如，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。又例如，本申请的各种不同的实施方式之间也可以进行任意组合，只要其不违背本申请的思想，其同样应当视为本申请所公开的内容。
