Description

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BWP(Bandwidth Part，带宽部分)的方案和装置。
背景技术
传统的无线通信中，网络设备通过DCI(Downlink Control Information，下行控制信息)对UE(User Equipment，用户设备)进行动态调度。为了降低盲译码(BD，Blind Decoding)所带来的复杂度，DCI尺寸对齐(size alignment)被提出以减少UE监测的DCI尺寸。
在NR(New Radio，新无线)系统中，BWP被提出以实现更加灵活的利用频谱。通常而言，一个服务小区在给定时刻只有一个活跃上行BWP和/或一个活跃下行BWP。
发明内容
DCI尺寸通常依赖与活跃BWP的参数配置；在BWP动态切换过程中，指示的BWP与活跃BWP不同可能会导致DCI尺寸的不匹配。发明人通过研究发现，当一个DCI的DCI格式能调度多个小区或者BWP时，上述问题会进一步加剧，因而需要新的解决方案。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然本申请的初衷是针对一个DCI调度多个小区或者BWP的场景展开说明，本申请也能用于一个DCI调度单个小区的传输场景中。进一步的，对不同场景(包括但不限于一个DCI调度多个小区和一个DCI调度单个小区)采用统一的设计方案还有助于降低硬件复杂度和成本。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任一其他节点中。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。
