Description

资源分配方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种资源分配方法、装置及存储介质。
背景技术
授权辅助接入(licensed assisted access，LAA)非授权频谱中，采用先听后说(listen before talk，LBT)的信道接入机制。
在NR非授权频谱(New Radio unlicensed，NR-U)中，基站等网络设备为每个终端在同一时刻配置一个激活(active)带宽部分(bandwidth part，BWP)。在网络设备具备有多个传输接收点(Transmission Reception Point，TRP)/天线面板(panel)场景下，每个TRP/panel给终端配置的active BWP是一样的，即带宽和频谱位置都一样。其中，Active BWP的带宽最大可以是与成员载波(Component Carrier，CC)带宽一样。在NR-U中，每个CC上最大带宽可以到100MHz，甚至400MHz，而LBT信道检测带宽单元最大为20MHz。故，对于每个终端，active BWP内可以包含多个LBT信道检测带宽单元。
在多TRP/panel场景中，配置给终端的active BWP包含多个LBT信道检测带宽单元场景下，在多个TRP/panel上如何为终端合理分配资源，是需要解决的问题。

进一步的，本公开中涉及的终端120，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。
在本公开实施例中，网络设备110与终端设备120可工作在非授权频谱上。在使用非授权频谱之前，网络设备110与终端设备120需采用先听后说(listen before talk，LBT)的信道接入机制，进行信道检测。所谓LBT也称之为信道侦听，具体是指，发送节点在进行数据发送之前，需要先对信道进行侦听，而在信道侦听成功后，再进行数据发送。信道侦听过程中，发送点检测周围非授权频谱上的信号接收强度(Received Signal Strength Indication，RSSI)值，若RSSI值高于门限，则表示周围有其它设备正在使用该非授权频谱，所以该发送点暂时不能使用；否则说明周围没有其它设备正在使用该非授权频谱，所以该发送点可以使用该非授权频谱进行数据传输。
网络设备110可以有一个或多个天线面板(panel)，其中，多个天线面板中的部分天线面板可能属于同一个传输接收点(transmission reception point，TRP)，也可能属于不同传输接收点。当不同天线面板属于不同传输接收点时，不同的天线面板也可以称为不同的传输接收点。在网络设备110有一个TRP(或panel)时，该TRP(或panel)若检测到非授权频谱信道被周围设备占用，则网络设备110不能使用该非授权频谱进行发送。而如果网络设备有多个TRP(或panel)时，每个TRP(或panel)周围使用该非授权频谱的情况不一样，可能TRP#0周围有其它设备使用，TRP#0暂时不能使用非授权频谱进行数据发送；而TRP#1周围没有其它设备使用，则TRP#1可以使用非授权频谱进行发送。所以当网络设备110有多个TRP或panel时，使用空间分集，可以提高非授权频谱的频谱效率。
LAA非授权频谱中，每个CC(即每个cell)上的最大带宽为20MHz，而LBT信道检测带宽最大可以为20MHz，所以每个CC上只有一个LBT信道检测带宽，这样整个CC上的信道检测结果一致，要么整个带宽空闲，要么整个带宽被其它设备占用。
在NR-U中，每个载波最大的信道带宽(Channel Bandwidth)可达到400MHz。但是考虑到终端120能力，终端120支持的最大带宽可以小于400MHz，且终端120可以工作在多个小的带宽部分(Bandwidth Part，BWP)上。网络设备110可以为终端120配置多于一个BWP，这时网络设备110需要告诉终端在哪一个BWP上工作，即激活(activate)哪一个BWP。该激活的BWP可以称为激活BWP(active BWP)。终端120在相应的active BWP上进行传输。其中，在非授权频段上，网络设备或者终端在active BWP上传输前也需要进行信道侦听，当信道为空闲时，才可传输信息。在NR-U中，每个CC上最大带 宽可以到100MHz，甚至400MHz，而LBT信道检测带宽单元最大为20MHz。故，对于每个终端，active BWP内可以包含多个LBT信道检测带宽单元(Bandwidth Unit，BWU)。
在网络设备具有多个TRP/panel场景下，多个TRP/panel给终端配置的active BWP可以是一样的，即带宽和频谱位置都一样。所以这里存在的问题是，当配置给终端的active BWP包含多个，比如图2所示active BWP包含5个LBT信道检测带宽单元，但是当两个TRP/panel在该active BWP上检测到信道空闲的LBT信道检测带宽单元不一样时，这两个TRP/panel如何给终端分配频谱资源，是需要解决的问题。
需要说明的是，图2给出的5个BWU是某个终端的active BWP包含的5个BWU，而网络设备在该CC上的带宽可能远大于这个5个BWU，比如网络设备的CC还包含BWU#0左侧即比BWU#0低频的多个BWU和比BWU#4高频的多个BWU，而未标示出来的这些BWU可能是别的终端的active BWP上的BWU。此处，本公开给出某个终端的active BWP包含的BWU的信道检测结果。
有鉴于此，本公开提供一种资源分配方法，针对网络设备具有多个天线面板时，在某个终端的当前active BWP中一部分的LBT BWU上检测到信道空闲的BWU，实现基站在多个天线面板上为终端合理分配资源。
图3是根据一示例性实施例示出的一种资源分配方法的流程图，如图3所示，该资源分配方法用于网络设备中，包括以下步骤。
在步骤S11中，基于至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU，确定第二BWP。
本公开中网络设备具有多个天线面板，该多个天线面板指具有至少两个天线面板。至少两个天线面板中各天线面板分别进行信道检测。其中，不同的天线面板可以是属于同一个TRP，也可以属于不同的TRP。其中，若不同的天线面板属于不同的TRP，则本公开中天线面板进行信道检测也可以理解为是TRP分别进行信道检测。
本公开中将各天线面板分别进行信道检测的BWP称为第一BWP，这里的第一BWP可以是网络设备在这个载波上的整个带宽部分。网络设备的各天线面板在第一BWP上分别进行LBT信道检测，以检测第一BWP中的LBT BWU是否为信道空闲的BWU。其中，各天线面板进行信道检测的过程可采用已有技术，本公开在此不再详述。
本公开中，各天线面板在第一BWP中的LBT BWU检测到空闲BWU时，网络设备在多个天线面板上为终端合理分配资源，例如基于检测到的信道空闲BWU重新确定active BWP。
本公开中将基于至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU所重新确定的active BWP称为第二BWP。
在步骤S12中，发送指示信令，该指示信令用于指示将第二BWP作为active BWP，和/或，用于指示第二BWP中各个BWU的信道空闲状态。
一方面，本公开中若第二BWP与终端当前使用的active BWP不相同，则网络设备向终端发送用于指示将第二BWP作为active BWP的指示信令，以使终端确定第二BWP为新的active BWP，并将当前active BWP切换为第二BWP。另一方面，本公开中若第二BWP与终端当前使用的active BWP相同，则网络设备无需向终端发送切换active BWP的指示信令。
本公开中，指示信令用于指示将第二BWP作为active BWP时，网络设备向终端发送下行资源调度指令，该下行资源调度指令用于调度终端接收下行信息的资源块(Resource Block，RB)。本公开中，用于调度终端接收下行信息RB的下行资源调度指令称为第一下行资源调度指令。
图4是根据一示例性实施例示出的另一种资源分配方法的流程图。参阅图4所示，该方法包括如下步骤。
在步骤S21中，基于至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU，确定第二BWP。
在步骤S22中，发送指示信令，该指示信令用于指示将第二BWP作为active BWP。
在步骤S23中，发送第一下行资源调度指令。第一下行资源调度指令用于调度终端接收下行信息的RB。
本公开中，下行信息可以是以下信息中的一种或多种的组合：下行参考信号，同步信号块，发现参考信号，下行控制信道(Physical Downlink Control Channel，PDCCH)上承载的信息，以及下行共享信道(Physical Downlink Share Channel，PDSCH)上承载的信息。
进一步的，本公开上述涉及的实施例中，指示信令用于指示将第二BWP作为active BWP，而指示信令没有指示第二BWP中各个BWU的信道空闲状态。这种情况下，终端默认第二BWP中的各个BWU都是信道空闲的，而网络设备发送第一下行资源调度指令时，需要避开信道非空闲的BWU上的RB，只调度信道空闲BWU上的RB来给终端发送下行信息。
本公开中，指示信令用于指示第二BWP中各个BWU的信道空闲状态，或指示信令用于指示将第二BWP作为active BWP和第二BWP中各个BWU的信道空闲状态时，网 络设备向终端发送下行资源调度指令，该下行资源调度指令用于调度终端在属于空闲状态BWU上的RB接收下行信息，不在属于非空闲状态的BWU上的RB上接收下行信息。本公开中将用于调度终端在属于空闲状态BWU上的RB接收下行信息，不在属于非空闲状态的BWU上的资源块RB上接收下行信息的下行资源调度指令，称为第二下行资源调度指令。
图5是根据一示例性实施例示出的另一种资源分配方法的流程图。参阅图5所示，该方法包括如下步骤。
在步骤S31中，基于至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU，确定第二BWP。
在步骤S32中，发送指示信令。指示信令用于指示第二BWP中各个BWU的信道空闲状态，或指示信令用于指示将第二BWP作为active BWP和第二BWP中各个BWU的信道空闲状态。
本公开中，指示信令指示第二BWP中各个BWU的信道空闲状态时，指示信令中包括针对第二BWP中每个BWU设置的信道空闲状态，信道空闲状态用于表征BWU的信道是否空闲。本公开针对每个BWU是指示一个信道空闲状态，或者针对各个天线面板指示多个状态。即，每个BWU对应的信道空闲状态的数量为1，或每个BWU对应的信道空闲状态的数量为N，N为正整数，且N小于或等于网络设备具有的天线面板个数。其中，指示信息针对每个BWU设置一个信道空闲状态时，网络设备的多个天线面板中只要有一个天线面板在该BWU上检测信道空闲时，则该BWU为信道空闲，否则为信道繁忙。或者指示信息针对每个BWU设置一个信道空闲状态时，网络设备的全部天线面板在该BWU上检测信道空闲时，则该BWU为信道空闲，否则为信道繁忙。每个BWU对应的信道空闲状态的数量为N时，N小于等于网络设备为该终端提供的天线面板的个数，比如网络设备有3个天线面板，但是只为该终端提供2个天线面板进行传输，那么每个BWU对应2个信道空闲状态，即每个空闲状态实际指示每个天线面板的信道检测结果。
在步骤S33中，发送第二下行资源调度指令。第二下行资源调度指令用于调度终端在属于空闲状态BWU上的RB接收下行信息，不在属于非空闲状态的BWU上的RB上接收下行信息。
本公开通过上述实施方式实现在网络设备具有多个天线面板的场景下，在多个天线面板上为终端配置active BWP，进而为终端分配资源。
进一步的，本公开上述涉及的实施例中，指示信令用于指示第二BWP中各个BWU 的信道空闲状态时，相当于网络设备指示了各个天线面板检测到BWU哪些是信道空闲BWU，进而使得接收到该指示信令的终端也能确定各个天线面板检测到的信道繁忙BWU，以及信道空闲BWU。故，网络设备在调度RB时，不需要避开非空闲BWU，即为了调度信令方便，可以同时调度空闲和非空闲BWU上的RB给终端，而实际上网络设备只在信道空闲的BWU的RB上发送了下行信息，在非空闲的BWU的RB上没有发送下行信息。而终端根据指示信令指示的各个BWU的信道空闲状态，只需要在信道空闲的BWU上相应的RB上接收下行信息，不需要在信道非空闲的BWU上相应的RB上接收下行信息。比如当第二BWP包含BWU#0，1，2时，且检测到信道空闲的BWU为BWU#0和BWU#2，而BWU#1是未检测到信道空闲的，所以网络设备分配频谱上的RB资源时会在这个三个连续的BWU上分配，用于指示分配资源的指示信令可能是包含BWU#0、BWU#1和BWU#2上的RB的，但是网络设备不会在BWU#1的RB上发送数据。进而终端在接收时，也不需要在BWU#1上接收数据。本公开中，网络设备调度时为了信令统一也可以调度繁忙BWU上的RB给终端，但是终端在接收数据时，不去繁忙BWU上接收数据，或者对繁忙BWU进行rate matching的操作。
进一步的，本公开中，网络设备根据各天线面板在第一BWP中的LBT BWU检测得到的不同信道检测结果，采用不同的方式确定active BWP。以下将结合实际应用对不同信道检测结果的不同处理方法进行说明。
一实施例中，至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU中包括有相同BWU。
其中，信道空闲BWU中包括有相同BWU有如下两种示例：示例一中，各天线面板在第一BWP中检测到的信道空闲BWU完全相同，即对于某个终端的active BWP而言，各天线面板的检测结果一样。例如，在图2中，TRP/panel#0检测到的信道空闲BWU为BWU#0和BWU#1，TRP/panel#1检测到的信道空闲BWU也为BWU#0和BWU#1。示例二中，各天线面板在第一BWP中检测到的信道空闲BWU部分相同。例如，在图2中，TRP/panel#0检测到的信道空闲BWU为BWU#0和BWU#1，TRP/panel#1检测到的信道空闲BWU为BWU#0。
本公开中，信道空闲BWU中包括有相同BWU时，在确定第二BWP时，在相同BWU组成的第一BWU集合中选择一个或多个BWU作为第一BWU子集，基于该第一BWU子集确定第二BWP。其中，基于第一BWU子集确定第二BWP时，基于第一BWU子集中各BWU的频谱位置连续性确定第二BWP。例如，第一BWU子集中包括频谱位置连 续的BWU时，将第一BWU子集中频谱位置连续的BWU确定为第二BWP。第一BWU子集中包括频谱位置不连续的BWU时，基于第一BWU子集中频谱位置连续的BWU，初步确定第二BWP。在初步确定的第二BWP中增加频谱位置不连续的BWU，得到最终确定的第二BWP，其中，增加的BWU中信道空闲BWU数量大于等于信道繁忙BWU数量。
本公开以下对信道空闲BWU中包括有相同BWU的两种示例中确定第二BWP的实施方式进行说明。
示例一：各天线面板在第一BWP中检测到的信道空闲BWU完全相同。
一示例中，当检测到的多个信道空闲BWU的频谱位置包括连续的BWU，且检测到的多个信道空闲BWU均为频谱位置连续的BWU时，配置该多个频谱位置连续的BWU，作为第二BWP。
其中，如果该多个连续的BWU合成的第二BWP与终端当前的active BWP不同，则网络设备需要发送用于指示将第二BWP作为active BWP的指示信令，以使终端确定新的active BWP，并将当前active BWP切换为新的active BWP(第二BWP)。
另一示例中，当检测到的多个信道空闲BWU包括频谱位置连续的BWU和频谱位置不连续的BWU时，配置频谱位置连续的BWU，作为第二BWP，并舍弃频谱位置不连续的BWU。
当然，本公开中也可设置某种准则来分配，比如尽可能均匀的让各个信道空闲的BWU分配给不同的终端。此时，本公开中网络设备需要发送指示信令，以指示终端新的active BWP。
又一示例中，当检测到的多个信道空闲BWU包括频谱位置连续的BWU和频谱位置不连续的BWU时，基于第一BWU子集中频谱位置连续的BWU，初步确定第二BWP。在初步确定的第二BWP中增加与该初步确定的第二BWP频谱位置不连续的BWU，得到最终确定的第二BWP。其中，增加的BWU中信道空闲BWU数量大于等于信道繁忙BWU数量，以尽可能多的将信道空闲的BWU包含到active BWP中，但是又要使active BWP中尽可能少的包含信道忙的BWU。例如，当信道空闲的BWU为BWU#0和BWU#4时，没有必要为了同时使用BWU#0和BWU#4，将BWU#0-BWU#4这5个BWU都配置在active BWP中，因为这样的话active BWP中只有2个信道空闲的BWU、却有3个信道繁忙不能使用的BWU，使得终端滤波器带宽较大而增加功耗。又例如，当信道空闲的BWU为BWU#0、BWU#1、BWU#2和BWU#4时，可将BWU#0-BWU#2确定为初步的第二 BWP，为了增加BWU#4，可以进一步将这5个BWU都配置为第二BWP，这样增加的非空闲的BWU数量是等于新增加的空闲BWU数量的。同时使得active BWP中有4个信道空闲的BWU、1个信道繁忙不能使用的BWU，即信道空闲的BWU数量是大于或等于信道忙的BWU数量的。
又一示例中，当检测到的多个信道空闲BWU为频谱位置不连续的多个BWU时，本公开中可将频谱位置不连续的多个BWU中的一个BWU视为用于初步确定第二BWP的频谱位置连续BWU，并采用与上述示例中检测到的多个信道空闲BWU包括频谱位置连续的BWU和频谱位置不连续的BWU时的相同处理方式确定第二BWP，即：在该频谱位置不连续的多个BWU中选择一个BWU作为初步确定的第二BWP。在初步确定的第二BWP中增加与该初步确定的第二BWP频谱位置不连续的BWU，得到最终确定的第二BWP。
本公开中，一方面，在初步确定的第二BWP中增加频谱位置不连续的BWU得到最终确定的第二BWP中若存在信道繁忙BWU，则网络设备发送用于指示第二BWP中各个BWU的信道空闲状态的指示信息，以使终端确定信道空闲BWU和信道繁忙BWU。另一方面，若预先定义终端默认的第二BWP中所包括的BWU均为信道空闲BWU，则网络设备无需额外发送指示第二BWP中各个BWU的信道空闲状态的指示信息，若第二BWP中实际存在信道非空闲的BWU时，网络设备调度时将不调度信道非空闲的BWU上的RB资源给终端。
其中，当第二BWP与当前active BWP不同时，网络设备需要发送用于指示将第二BWP作为新的active BWP的指示信令。
其中，当第二BWP与当前active BWP不同，且第二BWP中包含信道繁忙BWU时，网络设备需要发送指示将第二BWP作为新的active BWP的指示信令，也可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。
其中，当第二BWP与当前active BWP相同，且第二BWP中包含信道繁忙BWU时网络设备不需要发送将第二BWP作为新的active BWP的指示信令，但可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。
示例二：各天线面板在第一BWP中检测到的信道空闲BWU部分相同。
本公开中，若各天线面板在第一BWP中检测到的信道空闲BWU部分相同，部分不同，则使用各天线面板检测到的信道空闲且相同的BWU作为第一BWU集合，并在第一BWU集合中选择一个或多个BWU作为第一BWU子集，基于第一BWU子集确定第二 BWP。换言之，本公开中，若各天线面板在第一BWP中检测到的信道空闲BWU部分相同，部分不同，使用各天线面板检测到信道空闲的BWU的交集的子集，确定第二BWP，使得各个天线面板配置的第二BWP相同。比如在图2中，TRP/panel#0检测到的信道空闲BWU为BWU#0和BWU#1，TRP/panel#1检测到的信道空闲BWU为BWU#0，则将BWU#0确定为第二BWP。可以理解的是，本公开中各天线面板检测到信道空闲的BWU的交集的子集中包括不止一个BWU时，则基于所述第一BWU子集中各BWU的频谱位置连续性确定第二BWP。例如，将第一BWU子集中频谱位置连续的BWU确定第二BWP。或者基于所述第一BWU子集中频谱位置连续的BWU，初步确定第二BWP；在初步确定的第二BWP中增加频谱位置不连续的BWU，得到最终确定的第二BWP。其中，增加的BWU中信道空闲BWU数量大于等于信道繁忙BWU数量。
可以理解的是，本示例中当第二BWP与当前active BWP不同时，网络设备需要发送用于指示将第二BWP作为新的active BWP的指示信令。当第二BWP与当前active BWP不同，且第二BWP中包含信道繁忙BWU时，网络设备需要发送指示将第二BWP作为新的active BWP的指示信令，也可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。当第二BWP中包括有信道繁忙BWU时，网络设备可以发送用于指示第二BWP中各个BWU的信道空闲状态的指示信息，以使终端确定信道空闲BWU和信道繁忙BWU。例如，当第二BWP与当前active BWP相同，且第二BWP中包含信道繁忙BWU时，网络设备不需要发送将第二BWP作为新active BWP的指示信令，但可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。当预先定义终端默认第二BWP中包括的BWU均为信道空闲BWU，则网络设备无需额外发送指示第二BWP中各个BWU的信道空闲状态的指示信息，若第二BWP中实际存在信道非空闲的BWU时，网络设备调度时将不调度信道非空闲的BWU上的RB资源给终端。
另一实施例中，至少两个天线面板中各天线面板在第一BWP中检测到的信道空闲BWU中包括有不相同BWU。
本公开中，信道空闲BWU中包括有不相同BWU时，可以是信道空闲BWU中包括有部分不相同BWU，也可以是包括有完全不相同的BWU。
本公开中，各天线面板在第一BWP中检测到的信道空闲BWU中包括有不相同BWU时，采用如下两种方式确定第二BWP：
在一种实施方式中，在各天线面板在第一BWP中检测到的全部信道空闲BWU组成的第二BWU集合中选择一个或多个BWU作为第二BWU子集，基于第二BWU子集确 定第二BWP，以尽可能多的使用各个天线面板检测到的信道空闲BWU。本公开中，第二BWU集合可以理解为是各个天线面板检测到的信道空闲BWU的并集。第二BWU子集可以理解为是各个天线面板检测到的信道空闲BWU的并集的子集。其中，第二BWU子集内BWU的数量可以是一个也可以是多个，比如第二BWU子集内BWU的数量最大可以是各个天线面板检测到信道空闲的所有BWU。
可以理解的是，本公开中基于第二BWU子集确定第二BWP时，当第二BWP与当前active BWP不同时，网络设备需要发送用于指示将第二BWP作为新的active BWP的指示信令。当第二BWP与当前active BWP不同，且第二BWP中包含信道繁忙BWU时，网络设备需要发送指示将第二BWP作为新的active BWP的指示信令，也可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。当第二BWP中包括有信道繁忙BWU时，网络设备可以发送用于指示第二BWP中各个BWU的信道空闲状态的指示信息，以使终端确定信道空闲BWU和信道繁忙BWU。例如，当第二BWP与当前active BWP相同，且第二BWP中包含信道繁忙BWU时网络设备不需要发送将第二BWP作为新active BWP的指示信令，但也可以发送指示第二BWP中各个BWU的信道空闲状态的指示信息。当预先定义终端默认第二BWP中包括的BWU均为信道空闲BWU，则网络设备无需额外发送指示第二BWP中各个BWU的信道空闲状态的指示信息，此时网络设备进行资源调度时，不调度位于非空闲BWU上的RB来向终端发送下行信息。
在另一种实施方式中，基于各天线面板中指定天线面板在第一BWP中检测到的全部信道空闲BWU组成的第三BWU集合中选择一个或多个BWU作为第三BWU子集，基于第三BWU子集确定第二BWP。其中，指定天线面板检测到信道空闲BWU数量最多，且信道空闲BWU的频谱位置连续性最好。采用此种方式，实现以指定天线面板为主，确定第二BWP。这种情况下，网络设备去激活各天线面板中除所述指定天线面板以外的其它天线面板，并发送去激活信令。其中，去激活信令可以是媒体接入控制(Medium Access Control，MAC)信令。比如图2中，TRP/panel#0检测到信道空闲的BWU数目更多更连续，则配置第二BWP时以TRP/panel#0为主，比如使用TRP/panel#0为终端服务，TRP/panel#1进行去激活。利用MAC信令去激活TRP/panel#1，则终端即知道不用接收来自TRP/panel#1的下行传输。或者，本实施例中，网络设备发送表征指定天线面板的传输配置指示(Transmission Configuration Indication，TCI)状态，且不表征除指定天线面板以外的其它天线面板的TCI状态的下行资源调度指令，以下称为第三下行资源调度指令。其中，第三下行资源调度指令可以指示指定天线面板的TCI状态的，且不指示除指定天 线面板以外的其它天线面板的TCI状态。终端检测到第三下行资源调度中仅包括指定天线面板的TCI状态，可确定该指定天线面板相应的接收波束，并根据该指定天线面板相应的接收波束来接收下行信息。
其中，各天线面板在第一BWP中检测到的信道空闲BWU中为完全不相同的BWU时，若有一个天线面板检测到信道空闲BWU，除该检测到信道空闲BWU之外的其它天线面板未检测到信道空闲BWU，则该指定天线面板为该检测到信道空闲的天线面板。
本公开中，在进行资源分配时，根据各个天线面板检测到信道空闲BWU的频谱位置关系，确定终端新的active BWP，并进行资源分配，能够提高频谱效率的同时减少终端功耗。
图6是根据一示例性实施例示出的又一种资源分配方法的流程图。图6所示资源分配方法应用于终端，包括如下步骤。
在步骤S41中，接收指示信令。该指示信令用于指示将第二BWP作为激活BWP，和/或，用于指示第二BWP中各个BWU的信道空闲状态。
其中，指示信令用于指示第二BWP中各个BWU的信道空闲状态时，指示信令中包括针对第二BWP中每个BWU设置的信道空闲状态。信道空闲状态用于表征BWU的信道是否空闲。每个BWU对应的所述信道空闲状态的数量为1，或每个BWU对应的信道空闲状态的数量为N，N为正整数，且N小于或等于网络设备具有的天线面板个数。
其中，指示信令用于指示将第二BWP作为激活BWP，图6所示的资源分配方法还包括如下步骤：
在步骤S42a中，接收第一下行资源调度指令，在第一下行资源调度指令调度的RB上接收下行信息。由于指示信令没有指示第二BWP中各个BWU的信道空闲状态，那么终端默认激活BWP上的各个BWU都是信道空闲的。如果实际上第二BWP上是有信道非空闲的BWU时，网络设备调度时需要避开这些信道非空闲的BWU，即不调度信道非空闲BWU上的RB来向终端发送下行信息。
其中，指示信令用于指示第二BWP中各个BWU的信道空闲状态，或指示信令用于指示将第二BWP作为激活BWP和第二BWP中各个BWU的信道空闲状态，图6所示的资源分配方法还包括如下步骤：
在步骤S42b中，接收第二下行资源调度指令，在第二下行资源调度指令调度的属于空闲状态的BWU上的RB上接收下行信息，不在属于非空闲状态的BWU上的资源块RB上接收下行信息。由于指示信令包含了第二BWP上各个BWU的信道空闲状态，那么为 了调度信令的统一，即因为空闲BWU和非空闲BWU一起形成了一个频谱连续的第二BWP，所以调度信令指示了信道空闲BWU上的RB，也指示了信道非空闲BWU上的RB。而终端根据调度信令指示的RB以及各个BWU的信道空闲状态，确定需要在信道空闲的BWU上的RB上接收下行信息，不需要在信道非空闲的BWU上的RB上接收下行信息。
更进一步的，本公开中终端还可接收去激活信令，该去激活信令用于去激活各天线面板中除所述指定天线面板以外的其它天线面板。或者终端还可接收第三下行资源调度指令，第三下行资源调度指令表征所述指定天线面板的TCI状态，且不表征除指定天线面板以外的其它天线面板的TCI状态。
本公开中，对于终端执行的资源分配方法描述不够详尽的地方，可参阅上述实施例中的相关描述，在此不再赘述。
