技术领域
本申请涉及通信技术领域，尤其涉及一种资源分配方法及相关设备。
背景技术
近年来，通信技术水平得到显著提升，并得到迅速推广。随着通信技术深入工业、航天、民用等领域，传统的通信方式已难以适应当前社会经济的发展需求，无线通信技术应运而生。无线通信技术如第五代移动通信技术(the fifth generation mobile networks，简称为5G)等新一代移动通信技术在传输速度及成本方面具有显著优势，使实现数字化、智能化转型成为可能。
在5G等无线通信系统中，无线信号在传播过程中的能量衰减会随着无线信号的载波中心频点增加而加剧。具体地，在相同传播环境以及相同传输距离下，无线信号的频点越高，则无线信号的能量衰减越快。这意味着，频点较高的无线信号的覆盖范围相比频点较低的信号覆盖范围缩小，其中，高频段，如频率范围2(Frequency Range 2，FR2)频段的无线信号覆盖范围缩减更显著。
由于用户设备(User Equipment，UE)等终端受发射功率的限制，上行覆盖范围缩减更加明显。当UE处于信号弱覆盖区域时，可以通过多次传输(也称重复发送)的方式改善上行覆盖范围缩减的问题。其中，多次传输使用的资源(如随机接入资源)单次传输使用的资源可以共享或独立。
然而，基站等网络设备的无线资源，如上述随机接入资源，在不同地点、不同时刻使用率都可能不同，如果只使用独立分配或者资源共享，很难充分利用资源，导致了资源浪费。
发明内容
本申请提供了一种资源分配方法及相关设备，目的在于解决只使用独立分配或者资源共享，很难充分利用资源，导致了资源浪费的问题。
为了实现上述目的，本申请提供了以下技术方案：
本申请的第一方面提供一种资源分配方法。该方法可以由网络设备执行。网络设备是网络侧用于提供网络通信功能的设备，有些情况下也称作网元，网络设备通常可以是基站，基站的功能单元，或者是基站的功能单元的组合。
具体地，网络设备确定单次传输和多次传输的资源使用模式，该资源使用模式包括共享模式或独立模式，然后网络设备根据所述资源使用模式确定资源分配信息，该资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，接着网络设备向终端发送所述资源使用模式的模式配置信息和/或所述资源分配信息，以使得所述终端根据所 述模式配置信息和/或所述资源分配信息确定所述单次传输所使用的资源池和/或所述多次传输所使用的资源池，从所述单次传输所使用的资源池和/或所述多次传输所使用的资源池中确定目标资源进行消息传输。
在该方法中，网络设备可以结合资源的使用情况进行资源分配，例如资源足够时，网络设备可以为多次传输分配独立资源，又例如资源较少时，可以为多次传输分配与单次传输共享的共享资源。如此可以有效使用资源，避免资源浪费。
在一些可能的实现方式中，所述资源分配信息为物理随机接入信道(Physical Random Access Channel，PRACH)资源的分配信息。单次传输为基于PRACH的单次传输，所述多次传输为基于PRACH的多次传输。
该方法可以应用于随机接入场景，在信号覆盖弱的区域，终端可以通过多次传输进行上行覆盖增强，而网络设备可以根据PRAC资源的使用情况，决定单次传输、多次传输的资源使用模式，为单次传输、多次传输分配相应的PRACH资源，提高资源利用率。
在一些可能的实现方式中，资源使用模式为共享模式时，网络设备确定的资源分配信息包括指示共享资源的信息。如此，终端可以基于网络设备下发的资源分配信息，确定单次传输与多次传输的共享资源，由此可以实现利用该共享资源进行多次传输，提高资源利用率。
在一些可能的实现方式中，所述资源分配信息包括第一频域位置信息和/或第一时域位置信息，所述第一频域位置信息和/或第一时域位置信息用于指示多次传输的独立资源与共享资源的边界。
其中，共享模式可以是允许单次传输共享全部资源给多次传输的模式。相应地，网络设备可以通过指示多次传输的独立资源与共享资源的边界的一个频域位置信息和/或一个时域位置信息，实现指示共享资源。终端可以基于上述频域位置信息或时域位置信息确定共享资源，基于共享资源进行消息传输，提高资源利用率。
在一些可能的实现方式中，所述资源分配信息包括多个频域位置信息和/或多个时域位置信息，所述多个频域位置信息包括第一频域位置信息和第二频域位置信息，所述多个时域位置信息包括第一时域位置信息和第二时域位置信息，所述第一频域位置信息和所述第二频域位置信息用于指示多次传输的独立资源与共享资源在频域的边界、单次传输的独立资源与共享资源在频域的边界，所述第一时域位置信息和所述第二时域位置信息用于指示多次传输的独立资源与共享资源在时域的边界、单次传输的独立资源与共享资源在时域的边界。
其中，共享模式可以是允许单次传输共享部分资源给多次传输的模式。相应地，网络设备可以通过指示多次传输的独立资源与共享资源的边界的至少一个频域位置信息和/或至少一个时域位置信息，以及指示单次传输的独立资源与共享资源的边界的至少一个频域位置信息和/或至少一个时域位置信息，实现指示共享资源。终端可以基于上述频域位置信息或时域位置信息确定共享资源，基于共享资源进行消息传输，提高资源利用率。
在一些可能的实现方式中，共享模式包括允许所述多次传输共享使用所述单次传输的全部资源的模式，所述独立模式包括所述单次传输的全部资源不共享的模式。换言之，单次传输的资源可以全部共享给多次传输或者全部不共享给多次传输。相应地，当所述网络 设备确定的资源使用模式为所述共享模式时，网络设备向终端发送所述资源使用模式的模式配置信息，模式配置信息表征所述资源使用模式为所述共享模式；当所述网络设备确定的资源使用模式为所述独立模式时，所述网络设备向所述终端发送资源分配信息，所述资源分配信息指示所述单次传输的资源和/或所述多次传输的独立资源。
在该方法中，若网络设备确定资源使用模式为全部共享的共享模式，则网络设备可以下发该模式的模式配置信息，相应地，终端可以基于该模式配置信息经预先配置的资源池确定为共享的资源池，用于单次传输、多次传输共享使用。如此，只需要简单的模式配置，即可实现高效的资源分配。
在一些可能的实现方式中，当所述网络设备确定的资源使用模式为所述共享模式时，所述网络设备向所述终端发送所述资源分配信息。具体地，若网络设备未预先配置资源池，则网络设备可以向终端发送资源分配信息，例如是指示单次传输的资源和/或多次传输的独立资源的资源分配信息，以便于终端确定单次传输所使用的资源池和/或多次传输所使用的资源池，并基于资源池中的资源进行消息传输。
该方法中，终端可以结合模式配置信息以及资源分配信息快速确定单次传输所使用的资源池和/或多次传输所使用的资源池，提高了响应效率。
在一些可能的实现方式中，所述资源分配信息可以通过资源位图表示，所述资源位图中的一个或多个比特位用于表示一个资源，所述一个或多个比特位的值用于标识所述资源是否支持共享。
以随机接入场景为例说明。网络设备可以将一个同步信号块(synchronization signal block，SSB)周期内对应的PRACH资源按以下方式中的任意一种进行排列：将频域资源进行排列，并用位图的每一位表示每一个物理资源块(Physical Resource Block，PRB)资源；将时域资源进行排列，并用位图的每一位表示每一个时域资源；将随机接入时机(random access occasion，RO)资源进行排列，并用位图的每一位表示每一个RO资源。某个比特位为1，可以表示为该资源可共享用于多次PRACH传输和单次PRACH传输。
如此，终端可以基于资源位图中每一位的值确定共享资源，从而实现基于共享资源进行消息传输，提高资源利用率。
在一些可能的实现方式中，所述资源为随机接入时机RO资源、时域资源或频域中的物理资源块PRB资源。该方法通过对随机接入过程中的RO资源、时域资源或频域资源中的PRB资源进行分配，可以提高资源利用率。
本申请的第二方面提供一种资源分配方法，该方法可以由网络设备执行。具体地，网络设备确定单次传输和多次传输的资源使用模式，所述资源使用模式包括共享模式或独立模式，所述网络设备根据所述资源使用模式确定资源分配信息，所述资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，所述网络设备向终端发送所述资源分配信息，以使得所述终端根据所述资源分配信息确定所述单次传输所使用的资源池和/或所述多次传输所使用的资源池，从所述单次传输所使用的资源池和/或所述多次传输所使用的资源池中确定目标资源进行消息传输。
该方法中，网络设备先确定资源使用模式然后根据资源使用模式确定资源分配信息，资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，接着向终 端发送资源分配信息，以使得终端根据资源分配信息确定单次传输所使用的资源池和/或多次传输所使用的资源池，从资源池中确定目标资源进行消息传输。当资源足够时，网络设备可以为多次传输(如多次PRACH传输)分配独立资源；当资源较少时，可以为多次传输分配与单次传输共享的共享资源。如此可以有效使用资源，避免资源浪费。
在一些可能的实现方式中，网络设备向所述终端发送所述资源使用模式的模式配置信息，以使所述终端根据所述资源分配信息，结合所述模式配置信息，确定所述单次传输所使用的资源池和/或所述多次传输所使用的资源池。
在该方法中，网络设备还可以向终端发送资源使用模式的模式配置信息，例如是允许单次传输共享全部资源给多次传输的共享模式的模式配置信息，如此，终端可以结合模式配置信息、资源分配信息，快速确定单次传输所使用的资源池和/或所述多次传输所使用的资源池。
在一些可能的实现方式中，所述资源分配信息包括多次传输的独立资源的指示信息、多次传输的独立资源与共享资源的边界信息、单次传输的独立资源与共享资源的边界信息、单次传输的独立资源的指示信息中的一种或多种。
在不同资源使用模式下，资源分配信息有所不同。网络设备可以基于该网络设备确定的资源使用模式，确定向终端发送的资源分配信息，以便于终端能够基于该资源分配信息确定单次传输所使用的资源池和/或所述多次传输所使用的资源池，提高资源利用率。
在一些可能的实现方式中，所述边界信息通过时域位置信息和/或频域位置信息表征。该方法通过简单的时域位置信息和/或频域位置信息即可指示共享资源，减少了网络设备和终端的传输开销。

本申请实施例涉及的多个，是指大于或等于两个。需要说明的是，在本申请实施例的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请的技术方案可以应用于通信系统，例如可以是第二代(2G)通信系统、第三代(3G)通信系统，可以是LTE系统，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(5G New Radio，5G NR)系统，以及未来通信发展中出现的新通信系统，包括但不限于5G网络之后的移动通信系统(例如，6G移动通信系统)、车联网(vehicle to everything，V2X)通信系统等。
本申请适用的通信系统包括网络设备和终端。其中，网络设备是网络侧用于提供网络通信功能的设备，有些情况下也称作网元，网络设备通常可以是基站，基站的功能单元，或者是基站的功能单元的组合。通信系统的一种示例如图1所示，图1中包括基站1与终端2。
在本申请提供的实施例中，基站可以是具有无线收发功能的任意一种设备，包括但不限于：长期演进(long term evolution，LTE)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，新无线(new radio，NR)中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point，TRP)，3GPP后续演进的基站，Wi-Fi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站，或气球站等。基站可以包含一个或多个共站或非共站的传输点(Transmission Reception Point，TRP)。基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)，和/或分布单元(distributed unit，DU)。基站可以与终端进行通信，也可以通过中继站与终端进行通信。终端可以与不同技术的多个基站进行通信，例如，终端可以与支持LTE网络的基站通信，也可以与支持5G网络的基站通信，还可以与支持LTE网络的基站以及5G网络的基站进行双连接。
在本申请提供的实施例中，终端可以是各种形式，例如，手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。终端有时也可以称为终端设备、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定终端或者移动终端。
在图1所示的无线通信系统中，无线信号在传播过程中能量衰减会随着无线信号的载波中心频点增加而加剧。如图2所示，在相同的传播条件下，高频信号下行覆盖范围小于低频信号下行覆盖范围。而UE等终端受到发射功率的限制，其上行覆盖范围比下行覆盖范围更小，有必要对上行信号覆盖进行增强设计。
标准化机构如第三代合作伙伴计划3GPP所提出的3GPP Release 17标准(简称为R17)提供了针对物理上行共享信道(Physical Uplink Shared Channel，PDSCH)、物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)和第三消息(记作MSG3)的覆盖增强方案，但未提供物理随机接入信道(Physical Random Access Channel，PRACH)的覆盖增强。
PRACH覆盖增强是上行信道覆盖的一个瓶颈问题之一，在初始接入和波束失败恢复(也称作波束恢复，beam recovery)等过程中都非常重要。无论是初始接入，还是波束失败恢复，终端2通常需要通过PRACH向网络侧的基站1发起随机接入(random access)，以建立无线链路，通过无线链路进行数据交互操作。随机接入是指从用户通过物理随机接 入信道PRACH发送随机接入前导码(也可以简称前导码preamble)，开始尝试接入网络到与网络间建立起基本的信令连接之前的过程。
图3展示了一种随机接入的流程，图3以4步随机接入示例说明，如图3所示，基站如gNB可以预先配置PRACH资源，通过系统信息块(system information block，SIB)消息，如SIB2消息向终端2发送PRACH资源配置。终端2选择PRACH资源，通过选中的PRACH向基站1发送第一消息(记作MSG1)，其中，第一消息携带有随机接入前导码(Random Access Preamble，RAP)。基站1可以在PRACH中盲检前导码，如果检测到了前导码，则可以在随机接入响应(Radom Access Response，RAR)窗口内，通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)反馈第二消息(记作MSG2)，具体是随机接入响应RAR。
RAR中可以包括：MSG1中的Preamble(供终端2匹配操作)、终端2上行定时提前量(Timing Advance，TA)、backoff回退参数(重新发起Preamble码应延迟再次接入的时间)、为传输第三消息(MSG3)分配的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)调度信息UL_Grant(包括是否跳频、调制编码率、接入资源和接入时刻等内容)、Temple C-RNTI(供MSG3加扰使用)。
在4步随机接入流程中，PRACH传输(PRACH Transmission)发生在第1步(step1)。当UE处于信号弱覆盖区域(下行信号覆盖差通常都意味着上行信号覆盖更差)，PRACH传输可以通过如下方式增加覆盖：在一次PRACH Transmission中，终端2可以重复多次发送随机接入前导码(random access preamble，RAP)，其中，重复次数越多，信号覆盖范围越大。当一次PRACH Transmission失败(比如，未收到RAR消息)，终端2可以发起PRACH重传。在重传过程中，终端2可以切换波束或者调整发射功率。
然而，一次PRACH Transmission中preamble的重复发送次数有限，仍然可能出现随机接入失败，尤其是FR2场景下更容易出现上行覆盖不足的情况，随机接入失败的概率更高。如果进行PRACH Transmission重传，可能选择不同的preamble，基站1无法进行分集接收。此外，终端2等待失败后重传，还将带来随机接入时延。
基于此，终端2可以在同一个波束上发送进行多次PRACH Transmission。其中，波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束，形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术、模拟波束成形技术和混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。波束在NR协议中可以称为空域滤波器(spatial domain filter)，空间滤波器(spatial filter)，空域参数(spatial domain parameter)，空间参数(spatial parameter)，空域设置(spatial domain setting)，空间设置(spatial setting)，准共址(quasi-colocation,QCL)信息，QCL假设，或QCL指示等。波束可以通过TCI-state参数来指示，或者通过空间关系(spatial relation)参数来指示。
为了便于理解，本申请还提供一个示例对在同一个波束上进行多次PRACH Transmission的过程进行说明。如图4所示，在MSG1的发送过程中，终端2可以选择在相同的发送波束(transmission beam，Tx beam)，如Tx Beam x上重复多次发送PRACH Transmission，接收端(如基站1)也可以在相同的接收波束(reception beam，Rx beam)， 如Rx Beam x上，接收PRACH Transmission。发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
如此，基站可以将接收到的多次PRACH Transmission进行合并，从而提高接收信号的信干噪比(Signal to Interference plus Noise Ratio，SINR)，即提高通信系统中信号相对于干扰和噪声之和的比例，最终达到提高随机接入信号被正确接收的概率的目的。
对于使用相同发送波束的多次PRACH传输，为了区分多次PRACH传输和单次PRACH传输，可以在多次PRACH传输时使用与单次PRACH传输独立的preamble，在共享随机接入时机(random access occasion，RO)资源传输，或者是在多次PRACH传输时使用独立RO资源传输，又或者是在多次PRACH传输时，一部分使用独立的preamble在共享RO资源上传输，另一部分使用独立RO资源传输。RO资源可以是随机接入过程中能够传输前导码preamble的时频资源(时域资源、频域资源)。其中，时域资源、频域资源可以被分片，RO资源可以是能够传输前导码的时频资源分片或频域资源分片。
多次PRACH传输(Multiple PRACH transmission)与单次PRACH传输(Single PRACH transmission)资源独立、资源共享这两种方式各有优缺点，基站等网络设备的资源，如PRACH资源在不同地点、不同时刻使用率都可能不同，如果只使用独立分配或者资源共享，难以充分利用资源。
有鉴于此，本申请提供一种资源分配方法。该方法可以由网络设备执行。具体地，网络设备确定资源使用模式，例如根据资源的使用情况确定资源使用模式，然后网络设备根据资源的使用情况确定资源分配信息，资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，然后网络设备向终端发送资源使用模式的模式配置信息和/或资源分配信息，以使得终端根据模式配置信息和/或资源分配信息确定单次传输所使用的资源池和/或多次传输所使用的资源池，从资源池中确定目标资源进行消息传输。
在该方法中，网络设备可以结合资源的使用情况进行资源分配，例如资源足够时，网络设备可以为多次传输(如多次PRACH传输)分配独立资源，又例如资源较少时，可以为多次传输分配与单次传输共享的共享资源。如此可以有效使用资源，避免资源浪费。
基于图1所示的通信系统，本申请还提供一种资源分配方法。下面结合实施例，对本申请的资源分配方法进行详细说明。
参见图5所示的一种资源分配方法的流程图，该方法包括：
S502：网络设备确定单次传输和多次传输的资源使用模式。
单次传输是指在发送端和接收端仅进行一次传输，多次传输是指在发送端和接收端进行多次传输。其中，在进行多次传输时，发送端可以在相同发送波束上发送消息，接收端可以在相同接收波束上接收消息。
以随机接入场景为例，发送端可以为终端，接收端可以是网络设备。相应地，单次传输可以是为基于PRACH的单次传输，也称作单次PRACH transmission，多次传输为基于PRACH的多次传输，也称作多次PRACH transmission。单次PRACH transmission或者多次 PRACH transmission中的一次PRACH可以传输一个或多个前导码。当传输多个前导码时，还可以设置多个前导码的变化规则，以便于接收端基于该变化规则检测相应的前导码。
资源是指进行消息传输的资源。在随机接入场景中，资源可以为物理随机接入信道PRACH资源。其中，PRACH资源包括但不限于RO资源、时域资源、频域中的物理资源块(Physical Resource Block，PRB)资源。RO资源为随机接入过程中能够传输前导码的时频资源(时域资源、频域资源，也称作时域RO、频域RO)。其中，时域资源、频域资源可以被分片，RO可以是能够传输前导码的时频资源分片或频域资源分片。
单次传输和多次传输的资源使用模式是指单次传输和多次传输使用资源的模式。该资源使用模式可以包括共享模式或独立模式。在有些情况下，共享模式包括允许所述多次传输共享使用所述单次传输的全部资源的模式，所述独立模式包括所述单次传输的全部资源不共享的模式。在另一些情况下，共享模式可以包括全部共享模式或部分共享模式。其中，全部共享模式可以是单次传输的资源(如单次PRACH transmission的PRACH资源)全部共享给多次传输，部分共享模式可以是单次传输的资源部分共享给多次传输。
为了便于理解，本申请还以随机接入为例，对独立模式、共享模式进行说明。参见图6所示的两种随机接入的资源使用模式的示意图，如图6中左侧所示，资源使用模式为独立模式时，多次PRACH传输使用的资源池独立于单次PRACH传输使用的资源池，例如，单次PRACH传输使用的资源池中的RO资源不仅在时域独立，在频域也独立；如图6中右侧所示，多次PRACH传输使用的资源池与单次PRACH传输使用的资源池共享，例如，单次PRACH传输使用的资源池可以共享RO资源给多次PRACH传输使用。其中，图6以单次PRACH传输共享部分RO资源给多次PRACH传输示例说明，在本申请实施例其他可能的实现方式中，单次PRACH传输也可以共享全部RO资源给多次PRACH传输。
网络设备可以根据资源的使用情况确定单次传输和多次传输的资源使用模式。具体地，网络设备可以获取资源使用率，将资源使用率与资源使用率对应的阈值进行比较。若资源使用率大于或等于对应的阈值，则表明可分配资源不足，网络设备可以确定单次传输和多次传输的资源使用模式为共享模式。若资源使用率小于，则表明可分配资源充足，网络设备可以确定单次传输和多次传输的资源使用模式为独立模式。
需要说明的是，可分配资源占比也可以表征资源使用情况，可分配资源占比越高，表明资源使用越少，可分配资源占比越低，表明资源使用越多。网络设备可以获取可分配资源占比，将可分配资源占比与可分配资源对应的阈值进行比较。若可分配资源占比大于或等于对应的阈值，则表明可分配资源充足，网络设备可以确定单次传输和多次传输的资源使用模式为独立模式。若可分配资源占比小于对应的阈值，则表明可分配资源不足，网络设备可以确定单次传输和多次传输的资源使用模式为共享模式。
S504：网络设备根据资源使用模式确定资源分配信息。
资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池。根据资源使用模式不同，资源分配信息可以是不同的。进一步地，根据预先配置或默认配置不同，资源分配信息指示的信息可以不同。例如，网络设备预先配置有单次传输所使用的资源池或者默认配置单次传输所使用的资源池，则资源分配信息可以指示多次传输所使用的资源池。下面对网络设备确定资源分配信息的过程进行详细说明。
在一些可能的实现方式中，资源使用模式为共享模式时，网络设备确定的资源分配信息包括指示共享资源的信息。基于指示共享资源的信息可以确定单次传输所使用的资源池和/或多次传输所使用的资源池。
在一些示例中，资源分配信息包括第一频域位置信息和/或第一时域位置信息。所述第一频域位置信息和/或第一时域位置信息用于指示多次传输的独立资源与共享资源的边界。仍以随机接入场景示例说明，如图7所示，当允许单次PRACH传输的全部RO资源作为共享RO资源时，可通过一个频域位置信息或时域位置信息来指示多次PRACH传输的独立RO资源(独立资源的一种)与共享RO资源的边界。需要说明，图7以频域位置信息SizeforSeparateRO指示PRACH传输的独立RO资源与共享RO资源在频域的边界示例说明，时域位置信息指示PRACH传输的独立RO资源与共享RO资源在时域的边界可以参考频域位置信息指示RACH传输的独立RO资源与共享RO资源在频域的边界。此外，当SizeforSeparateRO＝0时，多次PRACH传输的独立RO资源数为0，即，不分配独立的多次PRACH传输资源池。
在另一些示例中，资源分配信息包括多个频域位置信息和/或多个时域位置信息。多个频域位置信息包括第一频域位置信息和第二频域位置信息，多个时域位置信息包括第一时域位置信息和第二时域位置信息，第一频域位置信息和所述第二频域位置信息用于指示多次传输的独立资源与共享资源在频域的边界、单次传输的独立资源与共享资源在频域的边界，第一时域位置信息和第二时域位置信息用于指示多次传输的独立资源与共享资源在时域的边界、单次传输的独立资源与共享资源在时域的边界。仍以随机接入场景示例说明，如图8所示，当允许单次PRACH传输的部分RO资源作为共享RO资源时，可通过2个频域位置信息或2个时域位置信息来指示共享RO资源。需要说明，图8以第一频域位置信息StartPRB和第二频域位置信息EndPRB两个参数来表示共享的资源池的位置，可以实现配置单次PRACH传输的部分RO资源形成共享RO资源池。
在另一些可能的实现方式中，共享模式包括允许所述多次传输共享使用单次传输的全部资源的模式，独立模式包括单次传输的全部资源不共享的模式。换言之，单次传输的全部资源(如单次PRACH传输的全部RO资源)可以共享给多次传输，或者单次传输的全部资源不共享给多次传输。相应地，资源分配信息可以指示所述单次传输的资源和/或所述多次传输的独立资源。根据预先配置、默认配置不同，资源分配信息可以指示不同信息，例如网络设备确定资源使用模式为共享模式，并且预先配置有单次传输的资源，则资源分配信息可以指示多次传输的独立资源。又例如网络设备确定资源使用模式为共享模式，且预先未配置单次传输的资源，也未设置单次传输的资源的默认值，则资源分配信息可以指示单次传输的资源和多次传输的独立资源。网络设备确定资源使用模式为独立模式，资源分配信息可以指示多次传输的独立资源。
资源分配信息也可以通过资源位图表示。其中，资源位图中的一个或多个比特位用于表示一个资源，例如是RO资源、时域资源或频域中的PRB资源，一个或多个比特位的值用于标识所述资源是否支持共享。
以随机接入场景为例说明。具体地，网络设备如gNB可以将一个同步信号块(synchronization signal block，SSB)周期内对应的PRACH资源按以下方式中的任意一种 进行排列：将频域资源进行排列，并用位图的每一位表示每一个PRB资源；将时域资源进行排列，并用位图的每一位表示每一个时域资源；将RO资源进行排列，并用位图的每一位表示每一个RO资源。某个比特位为1，可以表示为该资源可共享用于多次PRACH传输和单次PRACH传输。
S506：网络设备向终端发送资源使用模式的模式配置信息和/或所述资源分配信息，以使得终端根据模式配置信息和/或资源分配信息确定单次传输所使用的资源池和/或多次传输所使用的资源池，从单次传输所使用的资源池和/或多次传输所使用的资源池中确定目标资源进行消息传输。
在一些可能的实现方式中，当网络设备确定的资源分配信息指示共享资源的信息，网络设备可以向终端发送该资源分配信息。相应地，终端可以根据资源分配信息中指示共享资源的信息，如指示共享资源与独立资源的边界的频域位置信息和/或时域位置信息，确定单次传输所使用的资源池和/或多次传输所使用的资源池。在进行单次传输时，终端可以从单次传输所使用的资源池中确定目标资源，例如是随机选择一个资源作为目标资源进行消息传输。在进行多次传输时，终端可以从多次传输所使用的资源池中确定目标资源，例如是随机选择多个资源作为目标资源进行消息传输。
在另一些可能的实现方式中，资源使用模式包括全部共享的共享模式或全部不共享的独立模式。若网络设备确定资源使用模式为全部共享的共享模式，网络设备可以向终端发送该资源使用模式的模式配置信息，其中，模式配置信息表征所述资源使用模式为所述共享模式。进一步地，网络设备还可以向终端发送资源分配信息，该资源分配信息指示单次传输的资源和/或多次传输的独立资源。例如，网络设备未预先配置单次传输的资源的情况下，网络设备可以向终端发送指示资源使用模式为上述共享模式的模式配置信息以及指示单次传输的资源和多次传输的独立资源的资源分配信息。若网络设备确定资源使用模式为全部不共享的独立模式，网络设备可以向终端发送资源分配信息，该资源分配信息指示单次传输的资源和/或多次传输的独立资源。其中，单次传输的资源若预先配置或者有默认配置，资源分配信息也可以指示多次传输的独立资源。类似地，多次传输的独立资源若预先配置或者有默认配置，资源分配信息也可以指示单次传输的资源。
其中，资源分配信息采用资源位图表示时，网络设备也可以向终端发送资源位图，以便于终端根据资源位图确定单次传输所使用的资源池和/或多次传输所使用的资源池。
上述模式配置信息和/或资源分配信息可以封装在消息中，由网络设备通过广播方式，向终端发送消息，从而实现下发模式配置信息和/或资源分配信息。在一些可能的实现方式中，网络设备可以将模式配置信息和/或资源分配信息封装在系统信息块(system information block，SIB)消息中，例如是封装在SIB消息的载荷中，然后下发至终端。SIB消息可以包括SIB1消息或SIB2消息。SIB2消息为包括公共的无线资源配置信息，对接入网络设备的终端通用。因此，网络设备可以将模式配置信息和/或资源分配信息封装在SIB消息，尤其是SIB2消息中。
该方法中，网络设备先确定资源使用模式，例如根据资源的使用情况确定资源使用模式，然后根据资源使用模式确定资源分配信息，资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，接着向终端发送资源使用模式的模式配置信息和/ 或资源分配信息，以使得终端根据模式配置信息和/或资源分配信息确定单次传输所使用的资源池和/或多次传输所使用的资源池，从资源池中确定目标资源进行消息传输。当资源足够时，网络设备可以为多次传输(如多次PRACH传输)分配独立资源；当资源较少时，可以为多次传输分配与单次传输共享的共享资源。如此可以有效使用资源，避免资源浪费。
本申请还提供了资源分配方法的另一实施例，下面结合附图，对该实施例进行详细说明。
参见图9所示的另一种资源分配方法的流程图，该方法包括：
S902：网络设备确定单次传输和多次传输的资源使用模式。
其中，资源使用模式包括共享模式或独立模式。在一些示例中，共享模式可以是允许单次传输共享全部资源给多次传输的模式。在另一些示例中，共享模块可以包括部分共享或全部共享，其中，部分共享是指允许单次传输共享部分资源给多次传输，全部共享是指允许单次传输共享全部资源给多次传输。
网络设备可以根据资源的使用情况确定单次传输和多次传输的资源使用模式。具体实现过程可以参考S502，在此不再赘述。
S904：网络设备根据所述资源使用模式确定资源分配信息。
资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池。资源分配信息包括多次传输的独立资源的指示信息、多次传输的独立资源与共享资源的边界信息、单次传输的独立资源与共享资源的边界信息、单次传输的独立资源的指示信息中的一种或多种。根据资源使用模式不同，资源分配信息可以是不同的。其中，边界信息可以通过时域位置信息和/或频域位置信息表征。下面分别进行说明。
在一些可能的实现方式中，资源使用模式为共享模式时，例如是支持全部共享或部分共享的共享模式时，网络设备确定的资源分配信息包括指示共享资源的信息。根据共享模式不同，指示共享资源的信息可以是不同的。例如，共享模式为全部共享时，资源分配信息可以是多次传输的独立资源与共享资源的边界信息，包括但不限于第一频域位置信息和/或第一时域位置信息。第一频域位置信息和/或第一时域位置信息用于指示多次传输的独立资源与共享资源的边界。又例如，共享模式为部分共享时，资源分配信息可以是多次传输的独立资源与共享资源的边界信息、单次传输的独立资源与共享资源的边界信息，包括但不限于多个频域位置信息和/或多个时域位置信息。多个频域位置信息包括第一频域位置信息和第二频域位置信息，多个时域位置信息包括第一时域位置信息和第二时域位置信息，第一频域位置信息和所述第二频域位置信息用于指示多次传输的独立资源与共享资源在频域的边界、单次传输的独立资源与共享资源在频域的边界，第一时域位置信息和第二时域位置信息用于指示多次传输的独立资源与共享资源在时域的边界、单次传输的独立资源与共享资源在时域的边界。
在另一些可能的实现方式中，资源使用模式为允许单次传输共享全部资源给多次传输的共享模式时，网络设备确定的资源分配信息可以包括指示单次传输的资源和/或多次传输的独立资源的信息。
资源使用模式为独立模式时，网络设备确定的资源分配信息可以包括指示多次传输的独立资源的信息，也称作多次传输的独立资源的指示信息。例如网络设备预先配置有单次传输的独立资源的指示信息，网络设备确定的资源分配信息可以包括多次传输的独立资源的指示信息。需要说明的是，在有些情况下，网络设备确定的资源分配信息也可以包括指示单次传输的独立资源的信息。例如，网络设备预先配置多次传输的独立资源的信息，则网络设备确定的资源分配信息包括单次传输的独立资源的信息。
需要说明，资源分配信息也可以通过资源位图表示。其中，所述资源位图中的一个或多个比特位用于表示一个资源，所述一个或多个比特位的值用于标识所述资源是否支持共享。例如，资源位图中的每一个比特位表示一个资源，如时域资源、PRB资源、RO资源，该比特位的值为1时，表征相应资源支持共享。
此外，本实施例中的资源是指用于消息传输的资源，在随机接入场景中，该资源例如可以是PRACH资源。相应地，资源分配信息可以为物理随机接入信道PRACH资源的分配信息。单次传输为基于PRACH的单次传输，多次传输为基于PRACH的多次传输。
S906：网络设备向终端发送所述资源分配信息，以使得所述终端根据所述资源分配信息确定所述单次传输所使用的资源池和/或所述多次传输所使用的资源池，从所述单次传输所使用的资源池和/或所述多次传输所使用的资源池中确定目标资源进行消息传输。
具体地，当网络设备确定的资源分配信息包括指示共享资源的信息，则网络可以向终端发送资源分配信息，无需发送模式配置信息，相应地，终端侧可以根据资源分配信息中指示共享资源的信息即可确定单次传输所使用的资源池和/或所述多次传输所使用的资源池。
当网络设备确定的资源使用模式为允许单次传输共享全部资源给多次传输的共享模式，网络设备确定的资源分配信息指示单次传输的资源和/或多次传输的独立资源，网络设备不仅向终端发送资源分配信息，还可以向终端发送资源使用模式的模式配置信息。如此，终端可以根据所述资源分配信息，结合所述模式配置信息，确定所述单次传输所使用的资源池和/或所述多次传输所使用的资源池。
该方法中，网络设备先确定资源使用模式然后根据资源使用模式确定资源分配信息，资源分配信息用于指示单次传输所使用的资源池和/或多次传输所使用的资源池，接着向终端发送资源分配信息，以使得终端根据资源分配信息确定单次传输所使用的资源池和/或多次传输所使用的资源池，从资源池中确定目标资源进行消息传输。当资源足够时，网络设备可以为多次传输(如多次PRACH传输)分配独立资源；当资源较少时，可以为多次传输分配与单次传输共享的共享资源。如此可以有效使用资源，避免资源浪费。
以上对本申请的资源分配方法进行介绍，下面结合不同场景对本申请的资源分配方法进行介绍。
在第一种场景中，资源分配方法可以包括如下步骤：
Step1：gNB确定PRACH资源的资源使用模式。
模式一：多次PRACH传输与单次PRACH传输使用独立的资源池，RO资源相互独立。
模式二：多次PRACH传输与单次PRACH传输使用共享的资源池，RO资源共享。
Step2：gNB确定资源分配信息。
gNB确定资源分配信息的过程可以参见上文相关内容描述。
Step3：gNB通过广播方式向UE发送资源使用模式的模式配置信息和/或资源分配信息。
其中，SIB消息中携带“允许共享使用单次PRACH传输的RO资源”的信息表示采用上述模式二。资源分配信息指示单次PRACH传输的RO资源和/或多次PRACH传输的独立RO资源。
进一步地，SIB消息中未携带“允许共享使用单次PRACH传输的RO资源”的信息可以表示采用上述模式一。当然SIB消息中也可以通过携带“不允许共享使用单次PRACH传输的RO资源”的信息表示采用上述模式一。当采用上述模式一时，资源分配信息可以指示单次PRACH传输的RO资源和/或多次PRACH传输的独立RO资源。
Step4：UE根据资源分配信息确定单次PRACH传输的资源池和多次PRACH传输的资源池，从资源池中选择目标资源。
在此实施例中，单次PRACH传输的RO资源要么全部共享，要么不共享。
在第二种场景中，资源分配方法可以包括如下步骤：
Step1：gNB确定PRACH资源使用模式。
模式一：多次PRACH传输与单次PRACH传输使用独立的资源池，RO资源相互独立。
模式二：多次PRACH传输与单次PRACH传输使用共享的资源池，RO资源共享。
Step2：gNB确定资源分配信息。
gNB确定资源分配信息的过程可以参见上文相关内容描述。
Step3：gNB通过广播方式向UE发送资源分配信息，资源分配信息包含指示共享资源的信息。
指示共享资源的信息可以包括共享RO资源和多次PRACH传输的独立RO资源的边界信息。例如，当允许单次PRACH传输的全部资源作为共享RO资源时，可通过一个频域位置信息或时域位置信息来指示多次PRACH传输的独立资源与共享RO资源的边界。
指示共享资源的信息可以包括共享RO资源和多次PRACH传输的独立RO资源的边界信息以及共享RO资源和单次PRACH传输的独立RO资源的边界信息。例如，当允许单次PRACH传输的部分资源作为共享RO资源时，可通过两个频域位置信息和/或两个时域位置信息来指示多次PRACH传输的独立资源与共享RO资源的边界、单次PRACH传输的独立RO资源与共享RO资源的边界。
Step4：UE根据资源分配信息确定单次PRACH传输的资源池和多次PRACH传输的资源池，从资源池中选择目标资源。
