Description

信息发送方法、信息发送装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及信息发送方法、信息发送装置及存储介质。
背景技术
在R16新无线技术非授权频谱(New Radio–Unlicensed，NR-U)标准讨论和设计中，发送端在发送信息之前一般都要进行信道监听，只有在信道监听成功(也即确定监听信道上的干扰水平低于预定的干扰门限值)后，才能发送信息，即采用先听后说(listen before talk，LBT)的信道占用机制进行信息发送。发送端进行信道监听的过程叫做空闲信道评估(clear channel assessment，CCA)，发送端在CCA成功以后就可以发送信息。
为了保证覆盖范围以及抵抗路径损耗，通常使用基于波束(beam)的发送和接收。由于各个波束的空间方向不同，在各个波束上进行发送或者接收时的干扰也不相同。在NR中，网络设备会为发送端配置发送信息所使用的一个波束。发送端在发送信息前需要预先确定发送该信息所使用的发送波束。当在该确定的发送波束上进行LBT检测确定干扰水平高于预定的干扰门限值，则确定CCA失败，不进行信息发送。

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信息发送方法可应用于图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。终端和网络设备之间通过无线资源进行信息 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量和终端数量不做限定。
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，基站)、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。
相关技术中，终端与网络设备进行信息发送之前，作为信息发送端的一端(网络设备 或终端)采用LBT的信道占用机制进行CCA检测，发送端在CCA检测成功以后发送信息。
为了保证覆盖范围以及抵抗路径损耗，通常使用基于波束的发送和接收。在NR中，网络设备会为发送端配置发送信息所使用的波束。发送端在发送信息前需要预先确定发送该信息所使用的发送波束。其中，发送信息使用的波束可以是由网络设备配置的。例如，网络设备发送物理下行控制信道(Physical downlink control channel，PDCCH)信道的波束是网络设备使用媒体接入控制(Medium Access Control，MAC)信令半静态的配置的。网络设备发送动态调度的物理下行共享信道(Physical downlink shared channel，PDSCH)，其波束是网络设备使用调度该PDSCH的下行控制信息(Downlink Control Information，DCI)来指定的。网络设备发送的半静态配置(semi-persistent scheduling，SPS)的PDSCH的波束是网络设备通过无线资源控制(Radio Resource Control，RRC)层信令半静态配置的。终端要发送的物理上行控制信道(Physical Uplink Control Channel，PUCCH)信道的波束是网络设备使用MAC信令半静态的配置的。终端发送动态调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的波束是网络设备使用调度该PUSCH的DCI来指定的。终端发送的半静态配置的配置授权的PUSCH(configured grant PUSCH，CG-PUSCH)的波束是网络设备通过RRC层信令半静态配置的。发送端通常具有多个发送波束，由于各个波束的空间方向不同，当发送端在同一时刻在不同的发送波束进行LBT时，不同的波束上能够检测到的干扰并不相同。然而上述发送信息波束的配置过程中，网络设备通常是为一个发送信息提前配置或者指定一个波束。当在该波束上进行LBT检测确定干扰水平高于预定的干扰门限值，则确定CCA失败，不进行信息发送。
在5G系统中有一类要求高可靠性和低时延的业务类型，即超可靠低时延业务(Ultra reliability low latency，URLLC)。对于URLLC业务，希望能够及时传输。如果在非授权频段上传输URLLC业务，希望能够降低因为信道监听不成功而导致URLLC不能顺利发送的概率。
有鉴于此，本公开实施例提供一种信息发送方法，在该信息发送方法中，确定多个波束进行CCA检测，并在多个波束中的每一个波束各自对应的波束方向上进行CCA检测，可以提高CCA检测的成功率。在进行CCA检测成功的波束上进行信息发送，能够提高信息顺利发送的概率。
图2是根据一示例性实施例示出的一种信息发送方法的流程图，如图2所示，信息发送方法用于发送端中，该发送端可以是终端，也可以是网络设备，包括以下步骤。
在步骤S11中，确定进行CCA检测的多个波束。
本公开实施例中，在进行信息发送前，可以确定进行CCA检测的多个波束，使用多个波束进行CCA检测。
一种实施方式中，本公开实施例中针对每一个待发送的信道配置多个波束进行CCA检测。
在步骤S12中，基于多个波束中的每一个波束，在每一波束各自对应的波束方向上进行CCA检测。
本公开实施例中，针对确定进行CCA检测的多个波束中的每一波束分别进行CCA检测，并且每一波束在各自对应的波束方向上进行CCA检测，提高CCA检测成功的概率。
在步骤S13中，响应于多个波束中存在进行CCA检测成功的一个或多个波束，在进行CCA检测成功的一个或多个波束中确定进行信息发送的波束。
本公开实施例中，使用多个波束在每一波束各自对应的波束方向上进行CCA检测，若存在CCA检测成功的波束，则在检测成功的波束中确定用于信息发送的波束。其中，CCA检测成功的波束可以是一个波束也可以是多个波束。
在步骤S14中，基于确定的进行信息发送的波束，进行信息发送。
本公开实施例提供的信息发送方法中，确定多个波束进行CCA检测，并在多个波束中的每一个波束各自对应的波束方向上进行CCA检测，可以提高CCA检测的成功率。在进行CCA检测成功的波束中确定进行信息发送的波束，并基于确定的波束进行信息发送，能够提高信息顺利发送的概率。
本公开实施例以下结合实际应用对上述实施例涉及的信息发送方法的实施过程进行说明。
一种实施方式中，本公开实施例中进行CCA检测的多个波束可以是有网络设备指定的或配置的。可以理解为，发送端可以基于网络设备的配置信息，确定进行CCA检测的多个波束。进一步的，本公开实施例针对发送的信息，可以采用不同的配置信息指示进行CCA检测的波束。例如，信息包括SPS PDSCH的信息，配置信息包括RRC层信令配置的信息。或者信息包括CG-PUSCH的信息，配置信息包括RRC信令配置的信息。或者信息包括动态调度的PDSCH，配置信息包括调度PDSCH的DCI。或者信息包括PDCCH的信息，配置信息包括MAC信令或RRC信令配置的信息。或者信息包括PUCCH的信息，配置信息包括MAC信令或RRC信令配置的信息。
一种实施方式中，本公开实施例中进行CCA检测的多个波束之间可以具有优先级顺 序。其中，波束的优先级顺序可以是预先配置的，例如可以是网络设备预先配置的。例如，网络设备可以基于波束索引大小确定。一实施方式中，索引小的优先级顺序高于索引大的优先级顺序。
进一步的，网络设备可以进行波束优先级顺序的调整。一示例中，网络设备配置的波束包括波束1、波束2、波束3和波束4，并按照索引大小确定各波束的优先级顺序，即波束1、波束2、波束3和波束4的优先级顺序从高至低依次降低。在后续通信过程中，确定波束3和波束4进行信息发送的效果更好，此时，可以将波束3和波束4的索引重新编号为小于波束1和波束2的索引，进而实现波束优先级顺序的调整。
在确定用于进行信息发送的波束时，可以基于波束的优先级顺序，在进行CCA检测成功的一个或多个波束中确定进行信息发送的波束。
图3示出了本公开一示例性实施例中确定用于信息发送的波束的流程示意图。参阅图3所示，包括以下步骤S131和步骤S132。
在步骤S131中，确定CCA检测成功的一个或多个波束中各波束的优先级顺序。
本公开实施例中，可以基于波束的索引大小确定波束的优先级顺序。
在步骤S132中，基于波束的优先级顺序，在进行CCA检测成功的一个或多个波束中确定进行信息发送的波束。
本公开实施例中，可以选取最高优先级顺序对应的波束进行信息发送(优先级顺序最优先的波束进行信息发送)。例如，在进行CCA检测成功的一个或多个波束中选择波束索引最小的波束进行信息发送。
一示例中，对于SPS PDSCH，用于进行CCA检测的多个波束是由网络设备使用RRC层信令配置的。网络设备使用RRC层信令配置的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当网络设备在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，网络设备可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
另一示例中，对于CG-PUSCH，可用于进行CCA检测的多个波束是由网络设备使用RRC层信令配置的。网络设备使用RRC层信令配置的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当网络设备在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，网络设备可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
又一示例中，对于动态调度的PDSCH，可用于进行CCA检测的多个波束是网络设备 使用调度该PDSCH的DCI来指定的。网络设备使用DCI所指定的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当网络设备在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，网络设备可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
又一示例中，对于动态调度的PUSCH，可用于进行CCA检测的多个波束是网络设备使用调度该PUSCH的DCI来指定的。网络设备使用DCI所指定的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当终端在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，终端可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
又一示例中，对于PDCCH信道，可用于进行CCA检测的多个波束是网络设备使用MAC层信令或者RRC层信令配置的。网络设备使用MAC层信令或者RRC层信令配置的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当网络设备在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，网络设备可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
又一示例中，对于PUCCH信道，可用于进行CCA检测的多个波束是网络设备使用MAC层信令或者RRC层信令配置的。网络设备使用MAC层信令或者RRC层信令配置的多个波束之间具有优先级顺序，例如，优先级顺序基于波束索引大小表征。当终端在多个波束上各波束分别进行CCA检测，且存在CCA检测成功的一个或多个波束时，终端可以选取其中顺序最优先的波束发送信息，例如，选取波束索引最小的波束发送信息。
本公开实施例提供的信息发送方法中，确定多个波束进行CCA检测，并在多个波束中的每一个波束各自对应的波束方向上进行CCA检测，可以提高CCA检测的成功率。在进行CCA检测成功的波束中确定进行信息发送的波束，并基于确定的波束进行信息发送，能够提高信息顺利发送的概率。此种，信息发送方法可以适用于发送端具有多波束并在非授权频段上进行低时延业务信息的发送场景中，例如进行URLLC业务信息的发送。
本公开实施例中，发送端(终端或网络设备)基于多个波束进行CCA检测，并在CCA检测成功的波束上进行信息发送。接收端(网络设备或终端)可以基于配置的多个波束进行信息的接收。
基于相同的构思，本公开实施例还提供一种信息发送装置。
可以理解的是，本公开实施例提供的信息发送装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算 法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
