Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及无线通信中和副链路(Sidelink)相关的传输方法和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务定义了4大应用场景组(Use Case Groups)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。在3GPP RAN#80次全会上已启动基于NR的V2X技术研究。
发明内容
NR V2X和现有的LTE(Long-term Evolution，长期演进)V2X系统相比，一个显著的特征在于支持单播并支持基于副链路(SideLink)上的路损的功率控制。基于3GPP RAN1#97次会议的结果，当一个UE(User Equipment，用户设备)被同时配置了基于下行链路(Downlink)和副链路上的路损的功率控制，UE会选择两中方法各自产生的功率中的最小值。
发明人通过研究发现，上述方法在对副链路上PHR(Power Headroom Report，功率头空间汇报)的汇报会产生影响。针对上述问题，本申请公开了一种解决方案。需要说明的是，在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到其他两个节点中。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。

作为一个实施例，本申请要解决的问题包括：当副链路上的发送功率同时受到基于下行链路路损的功率控制和基于副链路路损的功率控制约束时，如何计算副链路上的PHR汇报。上述方法通过根据两种方法得到的功率的差值来确定汇报信息，解决了这一问题。
作为一个实施例，上述方法的特质在于：所述第一功率是基于下行链路路损得到的功率，所述第二功率是基于副链路路损得到的功率。所述第一功率和所述第二功率的差值被用于确定所述第一信息。
作为一个实施例，上述方法的好处包括：更准确的反应了副链路的功率头空间(Power Headroom)。
作为一个实施例，上述方法的好处包括：避免了基于下行链路路损的功率控制严重制约副链路上的发送功率从而导致副链路的性能下降。
