  • PC3 UE is a mobile phone type terminal device that supports a maximum transmit power of 23dBm.
  • PC2 UE is a mobile phone type terminal device that supports a maximum transmit power of 26dBm.
  • PC2UE can also be called high power UE (high power user equipment, HPUE).
  • 3GPP For NR UEs working on a single frequency band, 3GPP currently requires PC2 UE to report its maximum supported uplink transmission time ratio. Since the transmit power of PC2 is twice that of PC3UE, if the maximum uplink transmission time ratio scheduled by network equipment is less than 50 %, the UE can meet the average transmit power not more than 23dBm without any additional scheme, that is, meet the SAR requirement. Therefore, 3GPP requires the PC2 UE to report a value range of 50%-100% of the maximum supported uplink transmission time ratio. It can be understood that the greater the proportion of uplink transmission time reported by the UE, the stronger the UE's ability to control the transmit power, and the smaller the restriction on the scheduling of uplink transmission by the network device.
  • 3GPP stipulates that if the proportion of uplink transmission time actually scheduled by the network equipment exceeds the ability reported by the UE to meet the SAR requirements, the UE is allowed to generate uplink losses, which reflects the restriction on the scheduling of the network equipment.
  • SUL technology plays an important role in the evolution of 5G.
  • the characteristic of the SUL technology is that the network device configures multiple uplink carriers for the UE at the same time, but at the same time schedules the UE to transmit on only one uplink carrier on the multiple uplink carriers, and there is no simultaneous transmission. Therefore, when considering the SAR scheme of the PC2 UE working on the SUL frequency band combination, there are many differences from the existing uplink SAR scheme of the UL CA or EN-DC frequency band combination.
  • 3GPP specifies the signaling for PC2 high-power UE transmit power capability reporting:
  • 3GPP specifies the capability reporting of PC2 high-power UE SAR solution:
  • the ratio (60%-100%) of the UE's maximum supported uplink transmission time to the total transmission time resources is reported through the maxUplinkDutyCycle-PC2-FR1 per band signaling.
  • the duty cycle (dutycycle) under different TDD ratios on the LTE network side is reported through the maxUplinkDutyCycle-interBandENDC-TDD-PC2-r16 signaling.
  • the combination (dutycycleFDD, dutycycleTDD) is reported.
  • the key difference between the SUL band combination and the CA and EN-DC band combinations is that the SUL band and the TDD band are sent in turn instead of concurrently. Because there is no standardized SAR solution in 3GPP to ensure that the network equipment knows the ability of the PC2 UE to meet the SAR regulations in the SUL frequency band combination, that is, the UE cannot report the maximum uplink transmission time ratio of each uplink frequency band it supports, which affects the network equipment. The uplink scheduling of the UE results in low transmission efficiency. In addition, the maximum uplink transmission time ratio supported in the existing reporting method is 100%, and the network device cannot distinguish the UE capability of supporting a maximum transmit power of more than 26dBm. For example, if the UE can support 29dBm, it cannot further indicate a stronger capability.

技术领域
本申请涉及网络技术领域，尤其涉及一种通信方法及相关设备。
背景技术
各个国家的法规组织都对手机类型的用户设备(user equipment，UE)的射频能量辐射对人体的影响有着非常严格的要求，通常使用(specific absorption rate，SAR)来规定。SAR规定在一定时间内UE积累的对人体辐射能量不能超过规定的最大值。由于SAR的广泛使用，第三代合作伙伴计划(The 3rd generation partnership project，3GPP)对UE满足SAR法规有标准化的解决方案。对于功率类型(power class3，PC3)的UE，即最大允许发射23dBm功率的UE，3GPP认为不需要额外的方案就能满足各国规定的SAR要求。因此，在研究PC2的UE(最大允许发射26dBm功率的UE)的SAR方案时，在一定时间内平均发射功率小于等于23dBm一直作为所标准化方案的目标假设。
由于网络设备无法确定PC2 UE在补充上行(supplemental uplink，SUL)频段组合上满足SAR要求的能力，影响网络设备调度PC2的UE的效率，导致传输效率低。

在本申请所涉及的网络技术领域中，可以包括以下几种频段组合：
SUL频段组合(band combination，BC)：在新空口(new radio，NR)中作为UE服务小区的第二个上行，与传统上行相比，在SUL频段上没有耦合的下行接收。SUL频段组合可以 包括时分双工(time division duplexing，TDD)频段和SUL频段。网络设备可以通过为UE配置SUL频段组合来实现同一个小区中UE使用两个不同频段的上行载波轮流发送。在38.101-1和38.101-3中定义了所有SUL相关的频段组合。
上行载波聚合(uplink carrier aggregation，UL CA)：与SUL不同，网络设备配置上行载波聚合需要使用载波聚合的协议栈。若UE支持上行载波聚合相应的频段组合，网络设备可以为UE配置添加辅小区，并激活相应的上行，使得辅小区的上行和主小区的上行组成一个上行的载波聚合。
LTE和NR双连接(LTE-NR dual connectivity，EN-DC)：属于非独立(non-standalone)组网架构。UE在EN-DC配置下，可以在LTE和NR的两个不同频段上同时接受网络设备的上行调度。与SUL和UL CA两种独立(standalone)组网架构不同的是，对于EN-DC，UE在LTE(4G)频段上也接受调度，而对于SUL和UL CA，UE均只能在NR(5G)频段接受调度。
3GPP规定了两种类型的UE：PC3UE和PC2 UE。其中，PC3UE为支持最大发射功率23dBm的手机类型终端设备。PC2 UE为支持最大发射功率26dBm的手机类型终端设备。PC2UE也可以称为高功率UE(high power user equipment，HPUE)。
对于工作在单频段上的NR UE，目前3GPP要求PC2 UE上报其最大支持的上行传输时间占比，由于PC2的发射功率为PC3UE的两倍，如果网络设备调度的最大上行传输时间占比小于50％，该UE无需任何额外方案即可满足平均发射功率不超过23dBm，也即满足SAR要求。因此，3GPP要求PC2 UE上报支持的最大上行传输时间占比的取值范围为50％-100％。可以理解，UE上报其所支持的上行传输时间占比越大，该UE对发射功率的控制能力越强，对网络设备调度上行传输的限制也越小。同时3GPP规定，如果网络设备实际调度的上行传输时间占比超过UE所上报的满足SAR要求的能力，则允许UE产生上行损失，侧面反映了对网络设备的调度进行了限制。
SUL技术在5G演进中扮演着重要地位，通过为UE添加低频点的纯上行载波，配合C频段(C band)的下行大带宽，补充了5G上行覆盖的不足，大大提升了上行覆盖和容量，也为运营商灵活的部署5G提供了最直接的帮助。SUL技术的特点是，网络设备同时配置UE多个上行载波，但同时只调度UE在多个上行载波上的一个上行载波上进行传输，不存在同时发送的情况。因此在考虑工作在SUL频段组合上的PC2 UE的SAR方案时，与已有的UL CA或EN-DC的频段组合的上行SAR方案有很多不同之处。
3GPP规定了PC2高功率UE的发射功率能力上报的信令：
对于单频段PC2 UE，通过ue-PowerClass per band信令上报。对于EN-DC组合PC2 UE，powerClass per BC信令和powerClass per BC信令上报。对于NR CA组合PC2 UE，通过powerClass per BC信令上报。
3GPP规定了PC2高功率UE SAR方案能力上报：
对于单band SAR能力，通过maxUplinkDutyCycle-PC2-FR1 per band信令上报UE最大支持上行传输时间占总传输时间资源的比例(60％-100％)。对于EN-DC、UL CA组合SAR能力，在TDD+TDD频段组合下，通过maxUplinkDutyCycle-interBandENDC-TDD-PC2-r16信令上报LTE网络侧不同TDD配比下的占空比(dutycycle)。在FDD+TDD频段组合下，上报组合(dutycycleFDD，dutycycleTDD)。
SUL频段组合与CA和EN-DC两种频段组合方式的关键区别在于：在SUL频段和TDD频段上轮流发送而非并发。由于3GPP中没有标准化的SAR方案保证网络设备获知SUL频 段组合中PC2 UE满足SAR法规的能力，也即UE无法上报自身所支持的各个上行频段上的最大上行传输时间占比的能力，影响网络设备对UE的上行调度，导致传输效率低。另外，现有上报方法中支持的最大上行传输时间占比为100％，网络设备无法区别支持最大发射功率超过26dBm以上的UE能力，例如若UE可以支持29dBm，无法进一步指示更强能力。为了解决上述技术问题，本申请实施例提供了如下解决方案。
如图2所示，图2是本申请实施例提供的一种通信方法的流程示意图。本申请实施例中的步骤至少包括：
S201，网络设备向终端设备发送系统消息，所述系统消息包括在所述TDD频段上的上下行时隙配比。
S202，终端设备根据所述上下行时隙配比，确定在时分双工TDD频段上的第一上行传输时间占比X。
其中，第一上行传输时间占比X为终端设备在TDD频段上的最大上行传输时间占比。例如，如果上下行时隙配比为2:3，则第一上行传输时间占比X可以为40％。第一上行传输时间占比X表示在满足SAR要求的前提下，在一个特定周期内在TDD频段上支持的最大上行传输时间占全部时域资源的比例。其中，特定周期可以为大于1毫秒的周期，通常是一个无线帧的帧长度，例如10毫秒。
S203，终端设备根据所述第一上行传输时间占比X，确定第二上行传输时间占比Y，所述第二上行传输时间占比Y为所述终端设备在补充上行SUL频段上的最大上行传输时间占比。
其中，第二上行传输时间占比Y表示在满足SAR要求的前提下，在一个特定周期内在SUL频段上支持的最大上行传输时间占全部时域资源的比例。
需要说明的是，终端设备在TDD频段上按照第一上行传输时间占比X(最大值)来传输上行数据、和在SUL频段上按照第二上行传输时间占比Y(最大值)来传输上行数据，总的累计发射功率不超过预设阈值，这样才能满足SAR规定的在一定时间内终端设备积累的对人体辐射能量不能超过规定的最大值。其中，第一上行传输时间占比X或第二上行传输时间占比Y均为满足SAR要求的能力。
为了满足SAR法规的要求，在网络设备配置终端设备的最大发射功率时，终端设备可以根据自身能够使用的功率累计算法和功率回退策略进行自身发射功率的控制，从而达到满足在一定时间内累计发射功率不超过预设阈值的要求。其中，功率累计算法和功率回退策略在3GPP标准中不做规定，允许终端设备设计上的灵活性。
可选的，当0<＝X<＝1时，Y<＝(1-X)，Y的取值也可以小于0。特别的，当Y＝(1-X)时，表示终端设备的能力最强，网络设备可以调度终端设备的任何上行资源。当Y<0时，表示所述终端设备无法在所述SUL频段上发送第一上行数据，并且也无法在TDD频段上按照最大上行传输时间占比X发送第二上行数据。此时，终端设备可以在TDD频段上按照不超过(X+Y)的上行传输时间占比发送第二上行数据。例如，当X＝0.5，Y＝-0.1时，也即Y<0，终端设备无法在SUL频段上发送第一上行数据，可以在TDD频段上按照上行传输时间占比0.3(不超过0.4)发送第二上行数据。
S204，终端设备向网络设备发送第一消息，所述第一消息用于指示所述第二上行传输时间占比Y，其中，所述终端设备被配置为使用所述TDD频段和所述SUL频段传输上行数据。
可选的，终端设备可以在SUL频段上向网络设备发送第一消息。网络设备在SUL频段 上接收到第一消息之后，可以确定第二上行传输时间占比Y为终端设备在行SUL频段上的最大上行传输时间占比。
可选的，网络设备接收到第一消息之后，可以根据第一消息，调度终端设备在TDD频段上按照不超过X的上行传输时间占比传输所述上行数据，和在SUL频段上按照不超过Y的上行传输时间占比传输所述上行数据。特别的，网络设备可以调度终端设备在TDD频段上按照第一上行传输时间占比X传输上行数据，和在SUL频段上按照第二上行传输时间占比Y传输上行数据，也即调度终端设备按照最强能力来传输上行数据。
可选的，终端设备可以在TDD频段上按照不超过X的上行传输时间占比传输所述上行数据，和在SUL频段上按照不超过Y的上行传输时间占比传输所述上行数据。应注意，终端设备在TDD频段和SUL频段上轮流向网络设备发送上行数据，也即不是同时向网络设备发送上行数据。
可选的，如果网络设备调度终端设备在TDD频段上的实际传输时间占比超过第一上行传输时间占比X，或者在SUL频段上的实际传输时间占比超过第二上行传输时间占比Y，可以允许终端设备损失上行数据。
可选的，第一消息还可以用于调度终端设备的发射功率和上行数据。例如，如果终端设备不满足SAR要求，可以调度终端设备减小发射功率或减少上行数据。
可选的，所述第一消息还用于指示所述终端设备优先满足在所述TDD频段上的上行调度。如果网络设备在SUL频段上接收到终端设备的第一消息，该第一消息指示在SUL频段上的最大上行传输时间占比，相当于隐式指示优先满足在TDD频段上的上行调度，其次满足在SUL频段上的上行调度。
可选的，当Y<0时，第一消息还用于指示终端设备无法在所述SUL频段上发送第一上行数据，并且所述终端设备可以在所述TDD频段上按照(X+Y)发送第二上行数据。
其中，第一消息可以为无线资源配置(radio resources configuration，RRC)信令。
在本申请实施例中，终端设备通过向网络设备上报在SUL频段上的最大上行传输时间占比，网络设备可以根据最大上行传输时间占比，准确地确定终端设备满足SAR要求的能力。从而在满足SAR要求的能力下，调度终端设备在TDD频段和SUL频段上传输上行数据，提高上行调度的效率。

可选的，当0<＝X<＝1时，0<＝Y<＝(1-X)。特别的，当1<X<＝2时，表示终端设备的最大发射功率为29dBm。第一消息还用于指示终端设备的最大发射功率为29dBm，且支持在所述TDD频段上的实际最大上行传输时间占比为X/2。例如，当终端设备向网络设备上报的X为1.6时，也即1<X<＝2，表示终端设备支持的最大发射功率不是26dBm，而是29dBm。同时，该终端设备可以在TDD频段按照不超过0.8的上行传输时间占比来传输上行数据，这样能够满足SAR要求。
可选的，终端设备可以在TDD频段上向网络设备发送第一消息。网络设备在TDD频段上接收到第一消息之后，可以确定第一上行传输时间占比X为终端设备在行TDD频段上的最大上行传输时间占比。
可选的，如果网络设备调度终端设备在TDD频段上的实际传输时间占比超过第一上行传输时间占比X，或者在SUL频段上的实际传输时间占比超过第二上行传输时间占比Y，可以允许终端设备损失上行数据。

特别的，网络设备可以调度终端设备在TDD频段上按照第一上行传输时间占比X传输上行数据，和在SUL频段上按照第二上行传输时间占比Y传输上行数据，也即调度终端设备按照最强的满足SAR要求的能力来传输上行数据。
在本申请实施例中，终端设备通过向网络设备上报在TDD频段上的最大上行传输时间占比，网络设备可以根据最大上行传输时间占比，准确地确定终端设备满足SAR要求的能力。从而在满足SAR要求的能力下，调度终端设备在TDD频段和SUL频段上传输上行数据，提高上行调度的效率。
