具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、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 Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6 代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的传输处理方法进行详细地说明。
如图2所示，本申请实施例一种传输处理方法，包括：
步骤201，终端确定第一物理随机接入信道PRACH传输时机，其中第一PRACH传输时机与无线辅助设备的模拟波束对应。
这里，终端需要确定与无线辅助设备的模拟波束对应的PRACH传输时机，即第一物理随机接入信道(Physical Random Access Channel，PRACH)传输时机(Occasion)，以便后续发送Msg1。
步骤202，所述终端在所述第一PRACH传输时机发送第一消息Msg1。
这里，终端基于步骤201确定的第一PRACH传输时机(第一RO)，在该PRACH传输时机上发送Msg1。
这样，终端仅在与无线辅助设备模拟波束对应的PRACH传输时机传输Msg1，避免了无线辅助设备模拟波束轮询导致的随机接入流程时延增加的问题。
该实施例中，无线辅助设备可以是智能表面，也可以是中继设备(repeator)，也可以是反向散射设备(backscatter)，或者其他具有波束赋形的无线信号转发设备。无线辅助设备对网络侧设备可见且受网络侧设备控制，网络侧设备可决定无线辅助设备的模拟波束。
应该知道的是，智能表面如RIS的工作原理和设备结构为：RIS是由前端的人造表面和后端的控制模块组成。前端的人造表面由密集排列的人造器件单元构成；器件单元的器件特性受到器件的控制信号/偏置电压影响，不同的控制信号/偏置电压对应于不同的反射系数/折射系数；反射系数/折射系数的变化会影响反射信号/折射信号的相位和/或强度；微观上每个器件单元导致独立的反射/折射信号，宏观上这些信号叠加在一起进而实现对电磁波的操控。控制信号/偏置电压由后端的控制模块提供。RIS设备的实现方式有两种：一种是纯无源单元构成的RIS设备；另一种是有源单元与无源单元混合的RIS设备，其中RIS单元阵列中大部分单元为无源单元，少量单元为有源单元。无源单元即上述提及的新型器件单元，每个无源单元包含一个可控器件(例如PIN管，可变电容等)，可控器件的状态受RIS设备的控制模块控制。可控器件的状态对应于无源单元的不同电磁特性，例如无线信号的能量幅度、相位、极化方向。有源单元是包含射频链路单元，可以进行接收或者发送射频信号，对无线信号进行处理或者发送按照基站指令或者协议规则发送无线信号。有源单元的成本和功耗要高于无源单元，但是基于有源单元的信道测量结果相比于无源单元的信道测量结果更准确和简单。在混合RIS设备中，为了兼顾成本和信道测量方式，混合RIS设备的有源单元是少量的稀疏分布的。
RIS可以用于热点流量增强或覆盖空洞补盲的场景。未来的无线业务会出现极大流量的数据业务(例如AR/VR，高清视频等)，或者其他对无线信道要求很高的业务。为了方便表述，文中这种高要求的业务称为热点业务，其用户称为热点用户。针对于热点用户的热点需求，一种可行的解决方式是动态地增加到达热点用户的可用波束；服务小区动态地激活辅助设备(例如面板(pannel)，RIS)，从而增加热点用户的可用波束，满足热点业务需求。小区覆盖范围内的障碍物导致覆盖空洞，无线信号在空洞区域强度弱，通信质量受到影响；这种现象在高频波段/毫米波段更加常见。RIS是独立于基站的设备，可以部署在远离基站的位置，通过转发/反射基站的信号为覆盖空洞区域提供通信服务。通过合理的节点部署，RIS避免被遮挡物遮挡，保证良好的信号覆盖。
可选地，该实施例中，步骤201包括：
所述终端获取第一传输参数，所述第一传输参数是同步信号(Synchronization Signal and PBCH block，SSB)与所述无线辅助设备的相关参数；
所述终端在检测到第一SSB的情况下，根据所述第一传输参数，确定所述模拟波束与所述第一SSB对应的第一PRACH传输时机。
也就是说，终端在检测到第一SSB的情况下，按照获取的SSB与无线辅助设备的相关参数，确定无线辅助设备的模拟波束与该第一SSB对应的第一PRACH传输时机。这里，第一传输参数可以是系统消息携带的。
当然，该实施例中，所述终端获取第一传输参数还可以是获取信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)与无线辅助设备的相关参数，在检测到第一CSI-RS的情况下，按照获取的CSI-RS与无线辅助设备的相关参数，确定模拟波束与第一CSI-RS对应的第一PRACH传输时机。本申请实施例的下述内容对基于检测的第一SSB确定第一PRACH传输时机的实现进行描述，其实现适用于基于检测的第一CSI-RS确定第一PRACH传输时机，在此不再赘述。
可选地，所述第一传输参数包括以下至少一项：
SSB关联的所述模拟波束的数量；
与同一SSB相关联的各个所述模拟波束的出现时间信息；
PRACH传输时机的周期。
其中，SSB关联的模拟波束，可以是SSB波束覆盖区域内存在的模拟波束，可以由一个或多个无线辅助设备产生。同样的，对于与同一SSB相关联的各个所述模拟波束，也可以由一个或多个无线辅助设备产生，具体的模拟波束的转发形式由实际网络部署和基站配置决定。当然，SSB波束覆盖区域内存在的模拟波束也可以理解为SSB对应的模拟波束。
具体地，与同一SSB对应的各个所述模拟波束的出现时间信息可以包括出现时间段和出现周期。例如，一种可行的配置方式是，SSB1对应的模拟波束1和模拟波束2，SSB1的周期为5ms，模拟波束1和模拟波束2的出现周期为10ms，在连续的SSB1的周期内，模拟波束1在一个SSB1周期的出现时间段为第1-4ms，模拟波束2在下一个SSB1周期的出现时间段为第2-4ms。又或者另一种可行的配置方式是，SSB1对应的模拟波束1和模拟波束2，SSB1的周期为5ms，模拟波束1和模拟波束2的出现周期为5ms在连续的SSB1的周期内，模拟波束1在一个SSB1周期的出现时间段为第1-2ms，模拟波束2在同一个SSB1周期的出现时间段为第3-5ms。
其中，在该出现时间段内至少包括一个上行PRACH资源，用于传输随机接入的上行信号。
基于第一传输参数，可选地，该实施例中，所述根据所述第一传输参数，确定所述模拟波束与所述第一SSB对应的第一PRACH传输时机，包括：
所述终端根据所述第一传输参数，确定所述第一SSB关联的所述模拟波束的数量，以及，与所述第一SSB相关联的各个所述模拟波束的出现时间信息；
所述终端根据确定的所述模拟波束的数量以及出现时间信息，将各个所述模拟波束的出现时间内的PRACH传输时机作为所述第一PRACH传输时机。
首先，将由第一传输参数中第一SSB的相关参数，确定该第一SSB关联的模拟波束的数量，以及，与该第一SSB相关联的各个模拟波束的出现时间信息；之后，将各个模拟波束的出现时间内的PRACH传输时机作为第一PRACH传输时机。
可选地，所述与所述第一SSB对应的各个所述模拟波束的出现时间信息是：
预定义的；
预配置的；
所述第一传输参数直接指示的；或者，
所述第一传输参数映射指示的。
即，当第一SSB关联的各个模拟波束的出现时间信息是预定义的或预配置的，则按照预定义或预配置规则来确定。其中，预配置可以是基于系统消息的预配置。当第一传输参数包括第一SSB关联的各个模拟波束的出现时间信息，则可由第一传输参数直接指示确定。当第一传输参数包括与第一SSB关联的各个模拟波束的出现时间信息具有映射关系的其他信息，则可由该其他信息映射指示，该映射关系是预定义或预配置的。当然，对于存在预定义的第一SSB关联的各个模拟波束的出现时间信息，预配置的第一SSB关联的各个模拟波束的出现时间信息，第一传输参数包括第一SSB关联的各个模拟波束的出现时间信息，以及，第一传输参数包括与第一SSB关联的各个模拟波束的出现时间信息具有映射关系的其他信息中的至少两种情况时，第一SSB关联的各个模拟波束的出现时间信息可以按照特定的方式进行确定，该特定方式是预定义或预配置的。
假设，第一传输参数包括PRACH传输时机的周期，而PRACH传输时机的周期与第一SSB关联的各个模拟波束的出现时间信息相关联，则可以由PRACH传输时机的周期确定第一SSB关联的各个模拟波束的出现时间信息。例如，第一SSB关联的各个模拟波束的出现周期与PRACH传输时机(RACH Occasion，RO)周期T相关。例如，SSB与PRACH传输时机按照协议定义 规则确定关联关系，并且映射的起始时间为无线帧0。在SSB与PRACH传输时机映射过程中，以无线帧0为起点，第一SSB关联的前n个PRACH传输时机与无线辅助设备模拟波束0相关联，后续的n个第一SSB关联的PRACH传输时机与无线辅助设备模拟波束1相关联，以此类推。其中n为正整数，可以由协议预定义或者系统消息配置。
该实施例中，隐式指示的PRACH传输时机与无线辅助设备模拟波束的关联关系可如图5所示，系统消息显示配置各个PRACH传输时机与无限辅助设备模拟波束的关联关系可如图6所示。
该实施例中，第一传输参数可以是基于不同SSB波束分别配置的。
另外，考虑到当前场景对无线辅助设备的传输需求，可选地，该实施例中，所述终端在所述第一PRACH传输时机发送第一消息Msg1之前，还包括：
所述终端判断是否在与所述第一SSB对应的第一PRACH传输时机发送Msg1。
可选地，所述终端判断是否在与所述第一SSB对应的第一PRACH传输时机发送Msg1，包括：
所述终端检测第一信号的信号强度，并在检测到的信号强度小于第一阈值的情况下，确定在与所述第一SSB对应的第一PRACH传输时机发送Msg1；或者，
所述终端测量第一信号的信道相关性，并在测量到的所述信道相关性小于第二阈值的情况下，确定在用与所述第一SSB对应的第一PRACH传输时机发送Msg1。所述第一信号的信道相关性的测量方式可以是在两个不同时间段分别传输的两个第一信号，也可以是第一信号一次传输过程中占用多个符号上的信道相关性。
也就是，一方面，终端能够通过检测第一信号的信号强度，在检测到的信号强度小于第一阈值时，了解到当前场景下信号覆盖较弱需要无线辅助设备辅助，则确定在与第一SSB对应的第一PRACH传输时机发送Msg1。另一方面，终端能够测量第一信号的信道相关性，在测量到的信道相关性小于第 二阈值时，了解到信道受到影响，则确定在与第一SSB对应的第一PRACH传输时机发送Msg1。当然，若检测到的信号强度不小于第一阈值或测量到的信道相关性不小于第二阈值，终端使用终端与网络侧设备之间直接通信的随机接入流程进行随机接入。
可选地，所述第一信号包括：第一SSB；或者，与所述第一SSB准共址(Quasi co-location，QCL)的信号。其中，与SSB QCL的信号可以是参考信号，如信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或者解调参考信号(Demodulation Reference Signal，DMRS)。故，检测第一信号的信号强度可以是检测第一SSB、第一SSB QCL的CSI-RS或第一SSB QCL的DMRS的信号强度。同样的，测量第一信号的信道相关性是测量第一SSB、第一SSB QCL的CSI-RS或第一SSB QCL的DMRS的信道相关性。
具体地，以SSB为例，测量SSB的信道相关性可以比较前后两次接收的同一SSB的信道相关性，也可以比较前后两次接收的同一SSB中主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)的信道相关性。
可选地，该实施例中，步骤202包括：
所述终端在与所述第一SSB对应的第一PRACH传输时机中，按照第二传输参数重复N次发送Msg1；其中，
N等于所述第一SSB关联的所述模拟波束的数量；
所述第二传输参数在N次发送过程中保持不变。
例如，当第一SSB关联的模拟波束的数量为5时，Msg1需要重复5次传输。当然，每次传输是在对应模拟波束的PRACH传输时机上发送。
可选地，所述第二传输参数包括以下至少一项：
发送功率；
前导码；
占用的PRACH传输时机。
其中，发送功率可以SSB接收信号强度为基础换算得到。前导码(preamble)可以与协议中已定义的其他用途(例如4step RACH，2step RACH等)的preamble集合不同。占用的PRACH传输时机可以指示各模拟波束分别的PRACH传输时机，也可以指示全部模拟波束的PRACH传输时机。
在重复发送时，终端以特定的无线辅助设备模拟波束为起点(例如，模拟波束0对应的时间段内的RO)在多个RO上重复发送Msg1。
此外，除可采用上述方式确定第一PRACH传输时机之外，该实施例中，可选地，步骤201还包括：
所述终端在检测到第二SSB的情况下，获取所述第二SSB对应的控制资源集(Control resource set，CORESET)配置信息，其中CORESET配置信息用于指示CORESET的时频资源；
所述终端检测所述CORESET，确定与所述第二SSB对应的第一PRACH传输时机。
这样，终端基于检测到的第二SSB，通过获取第二SSB对应的CORESET配置信息，检测CORESET来确定第二SSB对应的第一PRACH传输时机。当然，该实施例中，还可以基于检测到的第二CSI-RS，通过获取该第二CSI-RS对应的CORESET配置信息，检测CORESET来确定第一PRACH传输时机。本申请实施例的下述内容对基于检测的第二SSB确定第一PRACH传输时机的实现进行描述，其实现适用于基于检测的第二CSI-RS确定第一PRACH传输时机，在此不再赘述。
其中，CORESET配置信息可以是系统消息携带的，也可以是与CORESET配置信息具有映射关系的其它信息指示的，例如，复用SSB相关联的CORESET#0。
可选地，所述终端检测所述CORESET，确定与所述第二SSB对应的第一PRACH传输时机，包括：
所述终端根据所述CORESET配置信息，检测到下行控制信息(Downlink Control Information，DCI)，且DCI用于动态调度PRACH传输时机的情况下， 确定与所述DCI动态调度的PRACH传输时机为所述第一PRACH传输时机；或者，
所述终端根据所述CORESET的相关参数，检测到物理下行控制信道PDCCH的解调参考信号DMRS的信号强度大于第三阈值或所述第二SSB的信号强度，且PDCCH用于传输动态调度PRACH传输时机的DCI的情况下，确定第一时间窗口内的PRACH传输时机为所述第一PRACH传输时机，其中所述第一时间窗口以所述CORESET为起点。
即，一方面，终端根据CORESET配置信息，在检测到动态调度PRACH传输时机的DCI时，将该DCI动态调度的PRACH传输时机作为第一PRACH传输时机。其中，在检测到该DCI时，还可以进一步在判断该DCI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)上DMRS的信号强度大于预设信号强度的情况下，将该DCI动态调度的PRACH传输时机作为所述第一PRACH传输时机。
另一方面，终端根据CORESET配置信息，在检测到PDCCH的DMRS，该DMRS的信号强度大于第三阈值或第二SSB的信号强度时，将第一时间窗口内的PRACH传输时机作为第一PRACH传输时机。第一时间窗口是以该CORESET为起点的，特定长度的时间窗，特定长度可由系统消息配置或协议预定义。上述两个所述第一PRACH传输时机的确定规则是同时满足的情况下确定第一PRACH传输时机，或者在其中一个条件满足的情况下确定第一PRACH传输时机，具体规则由协议定义或者系统消息配置。
该实施例中，DCI调度的PRACH传输时机，可以是专用于无线辅助设备模拟波束的随机接入PRACH传输时机。该DCI可通过包括PRACH传输时机时频资源位置集合、preamble集合、PRACH格式等信息，显式调度PRACH传输时机。或者，通过检测该DCI，将该DCI后的第二时间窗内的PRACH传输时机作为第一PRACH传输时机。这里第二时间窗的起点及长度可以由系统消息配置或协议预定义。
对于终端在第一PRACH传输时机发送Msg1，网络侧设备(如基站)在 接收到Msg1后，能够确定终端对应的无线辅助设备的模拟波束，从而完成第二消息Msg2的发送。其中，网络侧设备能够确定第二PRACH传输时机，该第二PRACH传输时机是终端对应的无线辅助设备模拟波束的PRACH传输时机；之后根据该确定第二PRACH传输时机计算随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier，RA-RNTI)，之后使用该RA-RNTI加扰Msg2，并发送。
其中，网络侧设备在第一PRACH传输时机包括多个PRACH传输时机的情况下，根据该多个PRACH传输时机上同一个preamble信号的信号强度是否满足预设条件，选择第二PRACH传输时机；或者，在第一PRACH传输时机包括一个PRACH传输时机的情况下，将该第一PRACH传输时机作为第二PRACH传输时机。
因此，可选地，该实施例中，所述终端在所述第一PRACH传输时机发送第一消息Msg1之后，还包括：
所述终端接收网络侧设备发送的第二消息Msg2；其中，Msg2使用随机接入无线网络临时标识RA-RNTI加扰，RA-RNTI是基于第二PRACH传输时机计算所得；
在所述第一PRACH传输时机包括多个PRACH传输时机的情况下，所述第二PRACH传输时机为所述多个PRACH传输时机上信号的信号强度满足预设条件的PRACH传输时机；
在所述第一PRACH传输时机包括一个PRACH传输时机的情况下，所述第二PRACH传输时机为所述第一PRACH传输时机。
而对应使用RA-RNTI加扰的Msg2，可选地，所述终端接收网络侧设备发送的第二消息Msg2，包括：
所述终端在所述第一PRACH传输时机对应多个PRACH传输时机的情况下，根据所述多个PRACH传输时机，计算得到多个RA-RNTI；
所述终端使用所述多个RA-RNTI检测Msg2。
该实施例中，第一阈值、第二阈值、第三阈值可以是预定义或预先设置 的。
该实施例中，检测到SSB(第一SSB或第二SSB)，还可以理解为检测到SSB完成下行时隙同步。
综上，本申请实施例的方法，在部署至少一个无线辅助设备的小区中，利用随机接入流程进行初步的无线辅助设备模拟波束的训练。通过无线辅助设备模拟波束与PRACH传输时机的静态或动态调度关系，在随机接入阶段获得转发波束的增益效果，同时避免无线辅助设备模拟波束轮询导致的随机接入流程时延增加。
