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多载波调度的传输方案和装置。
背景技术
LTE(Long-Term Evolution,长期演进)和5G无线蜂窝通信网络系统均支持多个载波被同时调度的场景,多载波调度场景下,基站通过发送多个DCI(Downlink Control Information,下行控制信息)去调度多个载波上的PDSCH(Physical Downlink Shared Channel,物理下行共享信道),以提高传输速率。多载波调度中的一个特点在于,每个PDSCH都需要一个DCI进行调度,一个DCI不能同时调度位于多个载波上的多个PDSCH。
在NR R17的讨论中,基于一个DCI调度多个载波上的PDSCH或PUSCH(Physical Uplink Shared Channel,物理上行共享信道)的课题被立项,相应的,如何通过一个DCI调度多个载波上的PDSCH或PUSCH的解决方案需要被研究和讨论。
发明内容
5G NR系统中,为了降低终端的盲检测复杂度,不同的DCI格式(Format)可以通过添加填充比特(Padding Bits)或截断(Truncation)的方式实现载荷尺寸(Payload Size)相同,进而保证终端在一个搜索空间(Search Space)中不会按照数量过多的不同的载荷尺寸进行盲检测,进而降低终端实现的复杂度。
在引入单个DCI调度多个服务小区的场景下,由于各个服务小区的调度是独立的,进而用于调度多个服务小区的DCI格式势必与传统的调度单个服务小区的DCI格式不同,且新引入的调度多个服务小区的DCI的载荷尺寸会比调度单个服务小区的DCI的载荷尺寸大很多,进而如何改进多个DCI格式之间的尺寸协调,将需要被重新考虑。
针对上述多载波调度的场景,本申请公开了一种解决方案。需要说明的是,在本申请的描述中,只是将多载波作为一个典型应用场景或者例子;本申请也同样适用于面临相似问题的其它场景,例如单载波场景多BWP(Bandwidth Part,带宽部分),或者针对不同的技术领域,比如除了动态调度之外的技术领域,例如测量上报领域,控制信令发送等其它非动态调度领域以取得类似的技术效果。此外,不同场景(包括但不限于多面板的场景)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下,本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中,反之亦然。特别的,对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS(Technical Specification,技术规范)36系列、TS38系列、TS37系列中的定义。
