Description

资源确定方法、资源确定装置及存储介质 技术领域
本公开涉及通信技术领域,尤其涉及资源确定方法、资源确定装置及存储介质。
背景技术
在新无线技术(New Radio,NR)中,例如通信频段在frequency range 2时,由于高频信道衰减较快,为了保证覆盖范围,需要使用基于波束(beam)的发送和接收。当网络设备(例如基站)有多个传输接收点(Transmission Reception Point,TRP)时,可以使用多个TRP为终端提供服务,包括使用多个TRP为终端发送。当然,在任意一代通讯技术中都可以存在类似的技术和缺陷,因此本公开中只是以NR作为例子来进行说明,但是并非对本公开实施例技术所应用的场景的限定。
相关技术中,使用多个TRP发送PDCCH的方案中,可以为终端配置接收该PDCCH的传输配置指示(transmission configuration indication,TCI)状态,TCI状态指示终端接收该PDCCH时使用的接收波束。例如为终端配置控制资源集(Control Resource Set,CORESET),并配置CORESET对应的TCI状态(TCI state),该TCI状态即为接收该CORESET资源上的PDCCH时的TCI状态。
其中,终端针对PDCCH的反馈信息需要在物理上行控制信道(physical uplink control channel,PUCCH)上传输。而PDCCH对应的PUCCH资源索引(index)可以采用PDCCH对应的CORESET的起始控制信道元素(Control channel element,CCE)的index和CORESET中CCE的数目来确定。那么相关技术中为实现多个TRP使用多个PDCCH candidate发送同样的下行控制信息时,例如当PDCCH重复发送时,可以为终端配置多个不同的CORESET。即当同一下行控制信息采用多个CORESET的PDCCH candidate传输时,其对应的PUCCH资源的index如何来确定是需要解决的问题。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的数据传输方法可应用于图1所示的无线通信系统中。参阅图1所示,该无线通信系统中包括终端和网络设备。终端通过无线资源与网络设备相连接,并进行数据的发送与接收。
可以理解的是,图1所示的无线通信系统仅是进行示意性说明,无线通信系统中还可包括其它网络设备,例如还可以包括核心网设备、无线中继设备和无线回传设备等,在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数目和终端数目不做限定。
进一步可以理解的是,本公开实施例的无线通信系统,是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术,例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access,WCDMA)、时分多址(time division multiple access,TDMA)、频分多址(frequency division multiple access,FDMA)、正交频分多址(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址(single Carrier FDMA,SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文:generation)网络、3G网络、4G网络或者未来演进网络,如5G网络,5G网络也可称为是新无线网络(New Radio,NR)。为了方便描述,本公开有时会将无线通信网络简称为网络。
进一步的,本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是:基站、演进型基站(evolved node B,eNB)、家庭基站、无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为NR系统中的gNB,或者,还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时,网络设备还可以是车载设备。应理解,本公开的实施例中,对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的,本公开中涉及的终端,也可以称为终端设备、用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备,例如,终端可以是具有无线连接功能的手持式设备、车载设备等。目前,一些终端的举例为:智能手机(Mobile Phone)、口袋计算机(Pocket  Personal Computer,PPC)、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外,当为车联网(V2X)通信系统时,终端设备还可以是车载设备。应理解,本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备与终端之间基于波束进行数据传输。基于波束进行数据传输过程中,网络设备(例如基站)可以使用多个TRP(多个TRP也称为Multi-TRP)为终端发送PDCCH。相关技术中,网络设备(例如基站)使用一个TRP为终端发送PDCCH时,为终端配置接收该PDCCH的TCI状态。例如,配置方法为:为终端配置一个CORESET比如CORESET#1,且配置终端接收该CORESET#1资源中的PDCCH时对应使用的TCI状态为TCI#1。并为终端配置一个搜索空间集(Search Space set,SS set),与CORESET#1关联。终端在接收SS set中resource上的PDCCH时,就使用TCI#1对应的波束进行接收。目前每个SS set只能与一个CORESET关联,每个CORESET只配置一个TCI状态(TCI状态也称为TCI state)。
本公开中网络设备与终端之间基于波束进行数据传输。基于波束进行数据传输过程中,当网络设备(例如基站)使用多个TRP(多个TRP也称为Multi-TRP)为终端发送PDCCH时,不同的TRP使用不同的波束发送。
进一步的,为了实现多个TRP发送同样的PDCCH来提高PDCCH的可靠性,目前有多种方法:
方法一:为一个CORESET配置两个TCI状态。配置一个SS set与该CORESET关联,则该SS set可以对应两个TCI状态;或配置两个SS set与该CORESET关联,每个SS set对应其中一个TCI状态。
方法二:配置一个SS set,该SS set与两个CORESET关联,每个CORESET对应一个TCI状态,则该SS set可以对应两个TCI状态。
方法三:配置两个CORESET,每个CORESET对应配置一个TCI状态,并分别配置SS set与两个CORESET分别关联。即配置了两个SS set,关联不同的CORESET和对应不同的TCI状态。
上述方法可以实现Multi-TRP发送PDCCH,不同的TCI状态对应不同的TRP。相关技术中,针对PDCCH的反馈信息需要使用的PUCCH资源的PUCCH资源索引可以采用PDCCH对应的CORESET的起始CCE的index和CORESET中CCE的数目来确定。然而,针对存在连接关系的多个候选物理下行控制信道(PDCCH candidate),当多个PDCCH candidate对应不同的CORESET时,这多个PDCCH candidate传输的同一下行控制信息对 应的PUCCH资源的index如何来确定是需要解决的问题。例如,连接关系表示多个PDCCH candidate用于PDCCH重复发送(repetition)。当PDCCH重复发送时,可以为终端配置多个不同的CORESET。例如,上述方法二和方法三使用两个CORESET。采用多个CORESET对应的PDCCH candidate来发送同一下行控制信息时,其对应的反馈信息需要使用的PUCCH资源的index如何来确定是需要解决的问题。
需要理解的是,多个PDCCH candidate使用不同的波束,但这多个PDCCH candidate对应的时域或频域资源可以一样或者不一样。
本公开提供一种资源确定方法,主要针对存在连接关系的多个PDCCH candidate发送同一下行控制信息时,其对应的PUCCH资源的目标资源索引确定的方法。其中,存在连接关系的多个PDCCH candidate中的每个PDCCH candidate各自均关联有不同的CORESET,和对应不同的TCI状态。例如,对于用于PDCCH重复发送的两个CORESET,采用其中一个CORESET对应的PUCCH资源index对应的资源。其中,一种实施方式中,可以基于CORESET的参数确定PUCCH的资源index,和/或,也可以根据CORESET确定出候选PUCCH资源,基于候选PUCCH资源的参数,确定PUCCH的资源index。

本公开实施例另一种实施方式中,根据N个CORESET确定出候选PUCCH资源索引,基于候选PUCCH资源索引,确定PUCCH的资源索引。
一种实施方式中,可以基于N个CORESET中各个CORESET的配置参数确定候选PUCCH资源索引。
本公开实施例提供的资源确定方法中,为描述方便将基于N个CORESET确定出的候选PUCCH资源索引称为第二资源索引。本公开实施例中,第一资源索引基于第二资源索引确定。第二资源索引为基于N个CORESET中各个CORESET的配置参数确定的N个候选资源索引。
图5是根据一示例性实施例示出的一种资源确定方法的流程图。参阅图5所示,资源确定方法应用于终端中,包括如下步骤。

比如,一示例中根据PDCCH的聚合等级(Aggregation Level,AL)来选择合适的PUCCH format。如果AL较大,说明信道条件好,可以选择短符号的PUCCH format。否则,选择长符号的PUCCH format。
一示例中,本公开实施例提供的资源确定方法中,响应于第二资源索引的PUCCH资源参数包括PUCCH资源对应的起始符号位置,基于所述N个PDCCH candidate携带的下行控制信息所调度的下行数据和/或所指示的下行控制信息的接收处理时长,以及所述PUCCH资源对应的起始符号位置确定第一资源索引。
