Description

通信方法、终端和网络设备 技术领域
本申请涉及通信领域，尤其涉及一种通信方法、终端和网络设备。
背景技术
在新无线(New Radio，NR)系统，如5G中，终端与基站间可以支持多种长时间长度的上行信道或上行信号。如终端可以使用第一个时隙中的一个时域符号来传输上行信道或上行信号。
在NR系统中，通常基站会为终端预留用于传输某个上行信道或上行信号的资源，这会使得NR系统中会存在大量的资源碎片。而且，预留的资源中可能只有少量的资源被实际用于的原上行信道或原上行信号的传输。
若这些资源碎片不能被其他信道或信号使用，则会造成资源的浪费，从而使得资源的利用率较低。

具体实施方式
为了便于理解，先从整体上描述能够实施本申请实施例的通信方法的通信系统的示例架构图。应理解，本申请实施例并不限于图1所示的系统架构中，此外，图1中的装置可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。
图1所示的通信系统包括终端110和网络设备120。终端110与网络设备120之间可以相互通信。
本申请实施例中，终端110也可称为用户设备(User Equipment，UE)。UE可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network)进行通信。UE又可称为接入终端、终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。UE可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备等。
本申请实施例中，网络设备120可以是全球移动通信(Global System for Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)系统中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站 (NodeB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是未来5G网络中的基站设备、小基站设备等，本申请对此并不限定。
终端110与网络设备120间可以使用一个时隙中的一个或多个时域符号来传输上行信号或上行信道，如传输物理上行控制信道(Physical Uplink Control Channel，PUCCH)。
通常情况下，网络设备120会为终端110预留用于传输某些上行信号或上行信道的资源，如为传输PUCCH预留资源，如图2所示。这会使得通信系统中会存在大量的资源碎片。若这些资源碎片不能被其他信道使用，则会造成资源的浪费，从而使得资源的利用率较低。
通信系统中为某些上行信号或上行信道预留资源，可能会导致为这些上行信号或上行信道预留的资源所占用的时域符号中的所有资源均不能被其他上行信号或上行信道所使用，从而会浪费预留的资源所占用的时域符号中的资源碎片，进而降低资源的利用率。
因此本申请提出了一种新的通信方法，使得终端能够网络设备的指示，充分合理地使用资源碎片来传输上行信道或上行信号，从而提高资源的利用率。
图3为本申请实施例的通信方法的示意性流程图。应理解，图3示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图3中的各个操作的变形。
S310，网络设备向终端发送第一指示信息，该第一指示信息用于指示第一资源。
S320，网络设备接收终端根据第一指示信息，使用第二资源中的第三资源发送的上行信道或上行信号，该第三资源为第二资源中与第一资源不重叠的资源
本申请实施例的通信方法中，网络设备向终端发送指示第一资源的第一指示信息，使得终端能够根据该第一指示信息的指示使用第二资源中与第一资源不重叠的第三资源来发送上行信道或上行信号，从而可以使得终端在避免使用第一资源的情况下，又可以充分利用第二资源中的资源，从而提高资源的利用率。
相对应地，本申请实施例的终端执行的通信方法的示意性流程图如图4 所示。应理解，图4示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图4中的各个操作的变形。
S410，终端接收网络设备发送的第一指示信息，该第一指示信息用于指示第一资源。
S420，终端根据第一指示信息，使用第二资源中的第三资源向网络设备发送上行信道或上行信号，第三资源为第二资源中与第一资源不重叠的资源。
本申请实施例的通信方法中，终端接收网络设备发送的指示第一资源的第一指示信息，能够根据该第一指示信息的指示使用第二资源中与第一资源不重叠的第三资源来发送上行信道或上行信号，从而可以使得终端在避免使用第一资源的情况下，又可以充分利用第二资源中的资源，从而提高资源的利用率。
图3和图4所示的通信方法中，第一资源可以网络设备为该终端或其他终端向网络设备发送上行信号或上行信道所预留的资源。
具体而言，第一资源可以是网络设备为该终端或其他终端向网络设备发送上行控制信道、上行探测信号或随机接入信道预留的资源。也就是说，第一资源可以是该终端或其他终端发送上行控制信道、上行探测信号或随机接入信道所使用的资源。如第一资源可以是该终端或其他终端发送PUCCH、上行探测参考信号(Sounding Reference Signal，SRS)或物理随机接入信道(Physical Random Access Channel，PRACH)使用的资源。
S320与S420中的上行信道的一种具体例子上行物理共享信道(Physical Uplink Shared Channel，PUSCH)。
其中，第二资源可以是终端发送上行信道或上行信号可以使用的资源，或是网络设备为终端预先分配的用于发送该上行信道或上行信号应使用的资源。
其中，第一指示信息可以具体用于指示第一资源所占用的时域符号，或者第一指示信息可以具体用于第一资源的时域位置和/或第一资源的频域位置。
更具体地，第一指示信息可以具体用于指示第一资源所占用的时域符号的位置和/或第一资源所占用的时域符号的数量。
若终端与网络设备预先约定或设置好第一资源所占用的时域符号的位置时，如第一资源所占用的时域符号为第一资源所属的时隙中最后的时域符 号时，第一指示信息可以只指示第一资源所占用的时域符号的数量，这样，终端也能根据第一指示信息的指示确定第一资源占用的时域符号的位置。
若第一指示信息用于指示第一资源占用的N个时域符号，N为非负数，则通常情况下，网络设备向终端发送第一指示信息，可以采用如下方式实现：网络设备向终端发送下行控制信令，下行控制信令携带该第一指示信息。
对应地，终端接收网络设备发送的第一指示信息，可以采用如下方式实现：终端接收网络设备房的下行控制信令，该下行控制信令携带该第一指示信息。
其中，下行控制信令具体可以是下行控制信息(Down-Link Control Information，DCI)。
可选地，上述下行控制信令还可以携带第二指示信息，该第二指示信息用于指示终端发送上行信道或上行信号。
换句话说，网络设备可以向终端发送下行控制信令，该下行控制信息携带第二指示信息，第二指示信息用于调度终端发送上行信道或上行信号。同时，该下行控制信令还携带第一指示信息，第一指示信息用于指示第一资源所占用的N个时域符号。这样，终端接收到该下行控制信令，根据第二指示信息的调度发送上行信号或上行信道时，还可以根据第一指示信息的指示确定发送该上行信号或上行信道应使用的资源，即第二资源中与第一资源不重叠的第三资源。
若N为0，则表示终端可以使用第二资源中的所有资源，即第三资源可以为第二资源。
下面以PUCCH和PUSCH为例，结合图5和图6介绍本申请实施例的通信方法中的资源使用示意图。
如图5所示，若网络设备为PUCCH预留的第一资源确实被对应的终端用于发送PUCCH，则网络设备可以向该终端和/或其他中发送第一指示信息，指示该第一资源占用的N个时域符号。这样，这些终端接收该第一指示信息后，可以使用第三资源传输PUSCH，第三资源占用除这N个时域符号之外的其他时域符号。
如图6所示，若网络设备为PUCCH预留的资源实际上没有被对应的终端用于发送PUCCH，则虽然为PUCCH预留资源占用N个时域符号，但是网络设备也可以向该终端和/或其他中发送第一指示信息，指示第一资源占用 0个时域符号。这样，这些终端接收该该第一指示信息后，可以使用第三资源来传输PUSCH，第三资源可以占用为PUCCH预留的资源占用的N个时域符号。
从图5和图6可以直观地看出，本申请实施例的通信方法中，网络设备可以通过用于指示第一资源的指示信息，使得终端可以灵活、合理和充分地使用网络设备预留的资源来发送上行资源或上行信道，从而提高资源的利用率。
若第一指示信息具体用于指示第一资源的时域位置和/或频域位置，则通常情况下，网络设备向终端发送第一指示信息，可以采用如下方式实现：网络设备向终端发送高层信令，该高层信令携带第一指示信息。
此时，S420中，终端发送的上行信道或上行信号可以是网络设备通过下行控制信令调度的上行信道或上行信号，如PUSCH，也可以是半静态的上行信道或上行信号，如半静态的PUSCH，也可以是无调度的上行信道或上行信号。
可选地，若第一指示信息用于指示第一资源占用的N个时域符号，则图4所示的通信方法的S420中，终端根据第一指示信息，使用第二资源中的第三资源向网络设备发送上行信道或上行信号，第三资源为第二资源中与第一资源不重叠的资源，包括：
终端根据第一指示信息，使用第二资源中的第三资源向网络设备发送上行信道或上行信号，第三资源占用的M个时域符号不包括N个时域符号，M为正整数。
相对应地，图3所示的通信方法的S320中，网络设备接收终端根据第一指示信息，使用第二资源中的第三资源发送的上行信道或上行信号，第三资源为第二资源中与第一资源不重叠的资源，包括：
网络设备接收终端根据第一指示信息，使用第二资源中的第三资源发送的上行信道或上行信号，其中，第三资源占用的M个时域符号不包括所述N个时域符号，M为正整数。
也就是说，网络设备可以通过第一指示信息指示终端第一资源占用的N个时域符号，这样，终端可以根据第一指示信息的指示使用不包括这N个时域符号的第三资源来发送上行信号或上行信道，从而可以避免终端使用第一资源来发送该上行信号或上行信道，以影响其他使用第一资源的上行信号或 上行信道的传输。
可选地，若第一指示信息用于指示第一资源的时域位置和/或频域位置，则在图4所示的通信方法的S420中，终端根据第一指示信息，使用第二资源中的第三资源向网络设备发送上行信道或上行信号，第三资源为第二资源中与第一资源不重叠的资源，包括：
终端确定第二资源中的资源单元的第一数量；终端根据第一数量，对上行信道或上行信号进行速率匹配，得到长度为第一比特数的输出序列，第一比特数为终端根据第一数量确定的；终端对输出序列进行调制，得到第一数量的调制符号；终端将第一数量的调制符号映射到第二资源中的资源单元上，其中，终端丢弃第一数量的调制符号中映射到第一资源单元上的调制符号，第一资源单元为第二资源中与第一资源中重叠的资源单元。
相对应地，图3所示的通信方法的S320中，网络设备接收终端根据第一指示信息，使用第二资源中的第三资源发送的上行信道或上行信号，包括：
网络设备在第二资源包括的资源单元中，获取上行信道或上行信号对应的调制符号，调制符号的数量等于第二资源包括的资源单元的数量；其中，网络设备丢弃从第一资源单元上获取的调制符号，第一资源单元为第二资源中与第一资源中重叠的资源单元。
其中，第二资源中的资源单元的第一数量，是指第二资源中的资源单元的数量。
具体而言，终端可以先确定可以用于发送上行信号或上行信道的第二资源中包括的资源单元的数量。然后终端根据第二资源中包括的资源单元的数量，对该上行信号或上行信道进行速率匹配，得到一个输出序列。该输出序列的比特数与第二资源中包括的资源单元的数量相关，或者说该输出序列的比特数是终端根据第二资源中包括的资源单元的数量确定的。终端对该输出序列进行调制，得到一定数量的调制符号，该调制符号的数量等于第二资源中包括的资源单元的数量。
也就是说，若第二资源中包括的资源单元的数量为第一数量，该输出序列的比特数为第一比特数，则第一比特数为终端根据第一数量确定的，且调制符号的数量等于第一数量。
接下来，终端将第一数量的调制符号映射到第二资源包括的资源单元中。具体映射过程如下：终端将第一数量的调制符号中的任意调制符号映射到第 二资源的资源单元中时，若该调制符号将要映射的资源单元为第二资源与第一资源重叠的资源中的资源单元，则终端丢弃该调制符号，即不会将该调制符号映射到该资源单元上；只要当调制符号将要映射的资源单元不是第二资源与第一资源重叠的资源时，才将该调制符号映射到对应的资源单元。
这样，虽然上行信号或上行信道的第一数量的调制符号均在第二资源的第一数量的资源单元中进行了映射，但实际上，第二资源与第一资源中重叠的资源单元上并没有映射有该上行信号或上行信道的调制符号，只有第二资源与第一资源中不重叠的资源单元上映射有该上行信号或上行信道的调制符号。此时，第二资源与第一资源中不重叠的资源单元即组成了第三资源。这种资源映射的过程也可以称为打孔。
假设第二资源中的资源单元的第一数量为k，则第一资源与第二资源重叠的资源单元的数量为s，则将上行信号或上行信道的k个调制符号映射到k个资源单元上时，这k个资源单元中的s个资源单元上实际没有映射该上行信号或上行信道的调制符号。
上述终端根据第一指示信息指示的第一资源发送上行信号或上行信道的方法中的资源映射的过程，可以使得终端在发送该上行信号或上行信道时，可以充分利用第一资源相关的资源碎片，又不会占用第一资源，影响其他上行信号或上行信道的传输。
应说明的是，网络设备丢弃从第一资源单元上获取的调制符号，是指网络设备获取第二资源的资源单元上承载的调制序号，以获取对应的上行信道或上行信号时，丢弃该第一资源单元上获取的调制符号。但是，该第一资源单元上的实际承载的调制符号是可以用于获取其他上行信号或上行信道的。
可选地，若第一指示信息用于指示第一资源的时域位置和/或频域位置，则在图4所示的通信方法的S420中，终端根据第一指示信息，使用第二资源中的第三资源向网络设备发送上行信道或上行信号，第三资源为第二资源中与第一资源不重叠的资源，包括：
终端确定第二资源中的第一资源单元的第二数量，第一资源单元为第二资源中与第一资源中不重叠的资源单元；终端根据第二数量，对上行信道或上行信号进行速率匹配，得到长度为第二比特数的输出序列，第二比特数为终端根据第二数量确定的；终端对输出序列进行调制，得到第二数量的调制符号；述终端将第二数量的调制符号映射到第二数量的第一资源单元上。
相对应地，图3所示的通信方法的S320中，网络设备接收终端根据第一指示信息，使用第二资源中的第三资源发送的上行信道或上行信号，包括：
网络设备在第二资源包括的资源单元中的第一资源单元上，获取上行信道或上行信号对应的调制符号，调制符号的数量等于第二资源包括的第一资源单元的数量，第一资源单元为第二资源中与第一资源中不重叠的资源单元。
其中，第二资源中的第一资源单元的第二数量，是指第二资源中的第一资源单元的数量。
具体而言，终端可以先确定可以用于发送上行信号或上行信道的第二资源与第一资源不重叠的资源单元(为了后续描述方便，将重叠的资源单元称为第一资源单元)的数量(为了后续描述方便，将该数量称为第二数量)。然后终端根据第二数量，对该上行信号或上行信道进行速率匹配，得到一个输出序列。该输出序列的比特数(为了后续描述方便，将该比特数称为第一比特数)与第二数量相关，或者说该第一比特数是终端根据第二数量确定的。终端对该输出序列进行调制，得到一定数量的调制符号，该调制符号的数量等于第二数量。
也就是说，若第二资源与第一资源重叠的第一资源单元的数量为第二数量，则第一比特数为终端根据第一数量确定的比特数，且调制符号的数量等于第二数量。
接下来，终端将第二数量的调制符号映射到第二资源包括的第二数量的第一资源单元中。具体映射过程如下：终端将第二数量的调制符号中的任意调制符号映射到第二资源的资源单元中时，若该调制符号将要映射的资源单元为第二资源与第一资源重叠的资源中的资源单元，则终端继续跳过该资源单元，继续映射下一个资源单元，直到确定该资源单元为第一资源与第二资源不重叠的资源单元，即第一资源单元时，才将该调制符号映射到对应的资源单元。
这样，只有第二资源与第一资源中不重叠的第一资源单元上映射有该上行信号或上行信道的调制符号。此时，第二资源与第一资源中不重叠的资源单元即组成了第三资源。
假设第二资源中的第一资源单元的第二数量为k，则可以将上行信号或上行信道的k个调制符号映射到k个第一资源单元。
上述终端根据第一指示信息指示的第一资源发送上行信号或上行信道 的方法中的资源映射的过程，可以使得终端在发送该上行信号或上行信道时，可以充分利用第一资源相关的资源碎片，又不会占用第一资源，影响其他上行信号或上行信道的传输。
