具体实施方式
首先，对本申请实施例所涉及的通信场景和部分词汇进行解释说明。
图1A为本申请实施例所涉及的通信场景的示例图一，图1B为本申请实施例所涉及的通信场景的示例图二，图1C为本申请实施例所涉及的通信场景的示例图三。
如图1A所示的LTE-NR共站部署的无线通信场景中，LTE用户设备(user equipment，UE)1为一个LTE终端(即可以使用LTE载波中的上下行资源与网络设备1进行信号传输)、NR UE1为一个NR终端(即可以使用NR载波中的上下行资源与网络设备1进行信号传输)，以及NR UE2为一个支持上行共享的NR终端(即可以使用NR载波中的上下行资源与网络设备1进行信号传输，以及还可以使用SUL资源与网络设备1进行上行传输)。可选地，若NR UE2使用NR载波中的上行资源(即非SUL资源)向网络设备1发送上行信号，由于NR载波频率较高路损较大或NR UE2功率受限等可能会导致网络设备1接收到的上行信号质量较差，无法正确接收上行信号，因此NR UE2可以使用SUL资源(低频路损较小)向网络设备1发送上行信号，从而提升了NR中的上行覆盖。本申请实施例中，信号传输还可以被描述为信息传输或数据传输。
如图1B所示的LTE-NR非共站部署的无线通信场景中，对于网络设备2，曲线1代表NR的上行覆盖区域的边界线，曲线2代表NR的下行覆盖区域的边界线，曲线2和曲线1之间的环形区域代表上下行覆盖不匹配的区域。其中，NR UE3为一个NR终端(即可以使用NR载波中的上下行资源与网络设备2进行信号传输)，以及NR UE4为一个支持上行共享的NR终端(即可以使用NR载波中的上下行资源与网络设备2进行信号传输，以及还可以使用SUL资源与网络设备3进行上行传输)。可选地，若NR UE4使用NR载波中的上行资源(即非SUL资源)向网络设备2发送上行信号，由于NR载波频率较高路损较大可能导致网络设备2接收到的上行信号质量较差，无法正确接收上行信号，因此NR UE4可以使用SUL资源向网络设备3发送上行信号(即NR UE4的下行发送节点和上行接收节点不在同一节点)，再可以由网络设备3将该上行信号发送至网络设备2，从而提升了网络设备2的NR中的一部分上行覆盖。可选地，如图1B所示，曲线2和曲线1之间的环形区域还需要通过其它多个LTE载波才能无缝提升NR中的上行覆盖(即一个NR载波需要多个SUL资源提升上行覆盖)。
由于网络设备部署导致的LTE和NR覆盖角度的差异，如图1C所示的LTE-NR共站部署的无线通信场景中，示例性地，NR小区1中的同步信号块(synchronization signal block，SSB)1与SUL2资源关联，NR小区1中除SSB1之外的其余SSB与SUL1资源关联，即通过SUL1资源和SUL2资源提升NR小区1的上行覆盖。示例性地，NR小区2中的SSB2 与SUL3资源关联，NR小区2中除SSB2之外的其余SSB与SUL2资源关联，即通过SUL2资源和SUL3资源提升NR小区2的上行覆盖。示例性地，NR小区3中的SSB3与SUL1资源关联，NR小区3中除SSB3之外的其余SSB与SUL3资源关联，即通过SUL1资源和SUL3资源提升NR小区3的上行覆盖。

本申请涉及的网络设备可以包括但不限于：基站(base station，BS)、发送接收点(transmission reception point，TRP)，其可以是一种部署在无线接入网中可以和终端进行通信的设备。其中，基站还可以称为无线接入网(radio access network，RAN)设备。本申请实施例涉及到的网络设备可以是全球移动通讯(global system of mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(nodeB，NB)，还可以是长期演进(long term evolution，LTE)中的演进型基站(evolutional node B，eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。其中，5G网络中的基站还可以称为gNB。
本申请所涉及的终端设备或网络设备可以包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(dentral processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操 作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。
本申请实施例中提供的随机接入过程可以包括下述步骤：
1、终端设备向网络设备发送随机接入前导码(Random Access Preamble)。
可选地，在终端设备发起随机接入之前，接收网络设备发送的上行资源的配置信息；其中，上行资源的配置信息可以包括但不限于以下至少一个：上行资源的频域信息和上行资源的公共配置信息。上行资源的频域信息可以包括但不限于以下至少一个：上行载波频点信息和上行子载波偏移信息。上行资源的公共配置信息可以包括但不限于以下至少一个：随机接入信道(random access channel，RACH)配置信息、物理上行共享信道(physical uplink shared channel，PUSCH)配置信息、物理上行控制信道(physical uplink control channel，PUCCH)配置信息、信道探测参考信号(sounding reference signal，SRS)配置信息和功率控制配置信息。RACH配置信息可以包括但不限于以下至少一项：物理随机接入信道(physical random access channel，PRACH)的时域(子帧、时隙、符号和/或周期等)资源、频域(资源块信息和/或是否跳频等)频域和码分复用(正交覆盖码和/或循环移位等)资源，即PRACH资源包括时域资源、频域资源和/或码域资源。
可选地，上行资源的配置信息可以携带于系统消息块(system information block，SIB)中；当然还可以携带于其它消息中，本申请实施例中对此并不作限制。
本实施例中，终端设备可以根据网络设备发送的上行资源的配置信息中携带的随机接入前导码资源，从中选择一个随机接入前导码(preamble)，并在上行资源的配置信息中所指示的PRACH资源上发送该随机接入前导码(即M1消息)。
2、网络设备向终端设备发送随机接入响应(Random Access Response)。
本实施例中，网络设备可以在其广播的上行资源的配置信息中的PRACH资源上盲检测随机接入前导码。若网络设备检测到了随机接入前导码，则会针对该随机接入前导码在物理下行共享信道(physical downlink shared control channel，PDSCH)中反馈随机接入响应(radom access response，RAR)。可选地，PDSCH中可以承载由至少一个媒体介入控制层(media access control，MAC)-子头(subheader)和至少一个RAR组成的MAC协议数据单元(protocol data unit，PDU)，一个RAR与一个MAC-subheader对应。其中，一个MAC-subheader中包含但不局限于：M1消息中的随机接入前导码标识(random access preamble identity，RAPID)。一个RAR(即M2消息)中可以包含但不限于以下至少一项：终端设备的上行时间提前量(time advance，TA)、回退参数、用于传输M3消息所分配的PUSCH上行调度信息(包括但不限于：是否跳频、调制编码率、接入资源和接入时刻等内容)和临时小区无线网络临时标识(radio network tempory identity，RNTI)。
可选地，RAR也可以是一个独立的MAC PDU，和/或可以承载于下行(downlink，DL)-共享信道(shared channel，SCH)中。
本实施例中，终端设备在发送完随机接入前导码后可以检测是否有针对其发送的随机前导码的RAR。示例性地，终端设备需要解码PDSCH所承载的响应自己的RAR内容。可选地，通过随机接入无线网络临时标识(random access radio network temporary identity，RA-RNTI)解码出物理下行控制信道(physical downlink control channel，PDCCH)，其中，PDCCH中携带PDSCH的资源分配信息。进一步地，终端设备根据PDSCH的资源分配信息继续解码PDSCH中的内容，从而得到携带RAR的MAC PDU。可选地，终端设备和网络设 备均可以根据用于承载M1消息的PRACH时频资源位置确定出RA-RNTI。
可选地，一个MAC PDU中可以包含多个RAR和多个MAC-subheader(一个RAR与一个MAC-subheader对应)，终端设备可以根据多个MAC-subheader中携带的RAPID分别与自己发送的随机前导码的标识进行对比；若该终端设备发送的随机前导码的标识与某个MAC-subheader中携带的RAPID相同，则该MAC-subheader对应的RAR为针对该终端设备发送的随机前导码的RAR，则进一步解码该MAC-subheader对应的RAR内容。
3、终端设备向网络设备发送M3消息。
本步骤中，若终端设备确定收到了网络设备针对其发送的随机前导码的随机接入响应，则终端设备根据RAR中携带的上行TA调整量可以获得上行同步，并在网络设备为其分配的上行资源中发送首次调度的上行传输(first scheduled UL transmission)(即M3消息)，可以使得不同终端设备的上行传输同时到达网络设备。示例性地，M3消息可以包括但不限于：无线资源控制(radio resource control，RRC)建链消息(connection request)和/或RRC重建消息(RRC connection re-establishment Request)。可选地，first scheduled UL transmission可以承载于上行(uplink，UL)-SCH。
4、网络设备向终端设备发送M4消息。
本实施例中，网络设备可以向终端设备发送竞争解决(contention resolution)(即M4消息)，以完成竞争解决。可选地，对于初始接入和重建的情况，M4消息中的MAC PDU会携带竞争解决标识(contention resolution identity)，例如RRC connection request和/或RRC connection re-establishment Request等。
进一步地，终端设备在解码PDCCH信道后，可以继续在PDSCH信道中获取M4消息中的MAC PDU内容，并与终端设备之前在M3消息中发送的公共控制信道(common control channel，CCCH)服务数据单元(service data unit，SDU)进行比较；若二者相同，则竞争解决成功。
当然，本申请实施例中涉及的随机接入过程还可以通过其它可实现方式，本申请实施例中对此并不作限制。
本申请实施例中涉及的SSB中可以包括但不限于以下信息中一个或者多个：主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和物理广播信道(physical broadcast channel，PBCH)。其中，PSS和SSS可以用于确定NR载波的物理小区(physical cell identity，PCID)，还可以用于终端设备获取下行时频同步。PBCH可以用于传输NR载波的主信息块(master information block，MIB)，还可以用于终端设备获取下行的系统帧号和SSB索引。MIB可以配置调度系统消息块(system information block，SIB)的控制信道的时频资源位置，以便于终端设备根据MIB可以获取到其他的系统消息，如最小剩余系统消息(remaining minimum system information，RMSI)等。
本申请实施例中涉及的网络设备可管理一个或多个小区(一个小区中可以有至少一个终端设备，终端设备在小区中可以与网络设备进行通信)。可选地，对应于一个小区，网络设备可以发送多个SSB(一个SSB可以有一个索引，可选地，可以通过PBCH的解调参考信号DMRS序列和/或PBCH承载的系统消息指示SSB的索引值)。其中，一个网络设备发送的多个SSB可以携带同一个物理小区标识(physical cell identity，PCID)。
为了使得从6G以下频段到6G以上频段都有合适的子载波间隔使用，以提高系统传输效率，NR中支持多种子载波间隔。可选地，可以使用15kHz、30kHz、120kHz、240kHz等子载波间隔发送SSB，并且可以在5ms的半帧窗口内可以发送多个SSB。
示例性地，当使用15kHz子载波间隔时，3GHz以下频段的NR载波的5ms半帧窗口，至多发送4个SSB，其中，1个SSB可以映射至4个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号；3GHz到6GHz频段的NR载波的5ms半帧窗口中，至多可以发送8个SSB。
示例性地，使用30kHz子载波间隔时，3GHz以下频段的NR载波的5ms半帧窗口中，至多发送4个SSB，其中，1个SSB可以映射至4个OFDM符号；3GHz到6GHz频段的NR载波的5ms半帧窗口中，至多可以发送8个SSB。
示例性地，使用120或240kHz子载波间隔时，NR载波的5ms半帧窗口中，至多可以发送64个SSB。
可选地，对于至多传输8个SSB的半帧窗口中，SSB索引由PBCH中的解调参考信号(demodulation reference signal，DMRS)序列指示；对于至多传输64个SSB的半帧窗口中，SSB索引的低3位由PBCH中的DMRS序列指示，以及SSB索引的高三位由系统消息指示，示例性地，系统消息可以包括但不局限于MIB、SIB、RMSI等。
本申请实施例中，终端设备和/或网络设备可以采用波束赋形(beamforming)技术收发信号。可选地，波束赋形又可以称为波束成型或空域滤波，是一种使用传感器阵列定向发送和接收信号的信号处理技术。其中，波束赋形技术可以通过调整相位阵列的基本单元的参数，使得某些角度的信号获得相长干涉，而另一些角度的信号获得相消干涉。
考虑到频率越高，对应的路损越大，可以通过增强波束的方向性以弥补高频带来的路损，即频率越高，需要的波束越多。示例性地，高频载波需要通过多个波束或通过波束扫描实现整个小区的覆盖。
可选地，初始接入时终端设备会盲检SSB以获取下行的时频同步，并可以获取SSB的索引信息，还可以根据SSB来区分不同的波束；其中，一个SSB可以对应一个波束，或者一个SSB对应多个波束。示例性地，对于6GHz以下频段小区覆盖对波束数目的需求比较小，一个SSB可以对应一个波束；对于6GHz以上频段小区覆盖对波束数目的需求比较大，一个SSB可以对应多个波束(可选地，可以将同一SSB的索引所对应的至少一个波束看成一个波束)。
考虑到网络设备可以发送多个SSB，本申请实施例中涉及的第一SSB是指：终端设备从第一网络设备接收的至少一个第二SSB中确定出的第一SSB；其中，第二SSB的下行测量值大于SSB选择门限。示例性地，终端设备可以根据至少一个第二SSB的下行测量值，确定下行测量值中最大的第二SSB为第一SSB；例如，假设终端设备接收到了5个SSB，且其中SSB11、SSB13和SSB15的下行测量值(如SSB13的下行测量值大于SSB15的下行测量值，SSB15的下行测量值大于SSB11的下行测量值)大于SSB选择门限，则终端设备确定SSB11、SSB13和SSB15中下行测量值最大的SSB(如SSB13)为第一SSB。示例性地，终端设备可以从接收的至少一个第二SSB中随机确定第一SSB。当然，还可通过其它方式从至少一个第二SSB中确定第一SSB，本申请实施例中对此并不作限制。
本申请实施例中涉及的下行参考信号可以是终端设备选择的用于进行随机接入的SUL资源所对应的网络设备(如第三网络设备，其中，第三网络设备可以和第一网络设备相同，也可以是与第一网络设备不同的网络设备)发送的参考信号，用于终端设备确定利用SUL资源进行随机接入时的上行路损和/或区分多个同频的SUL资源。
可选地，当本申请实施例中涉及的下行参考信号是NR中的参考信号时，则该下行参考信号可以包括：SSB或信道状态信息参考信号(channel state information reference signal，CSI-RS)等参考信号；当本申请实施例中涉及的下行参考信号是LTE中的参考信号时，该下行参考信号可以包括：小区参考信号(cell reference signal，CRS)或CSI-RS等参考信号。
本申请实施例中涉及的下行参考信号的配置信息可以用于指示以下至少一项：携带下行参考信号的下行资源的位置信息、下行参考信号对应的发射功率信息以及下行参考信号所在载波的PCID信息。可选地，下行参考信号的配置信息可以包括但不限于以下至少一项：携带下行参考信号的下行资源的绝对频点号、携带下行参考信号的下行资源的绝对频点号与携带下行参考信号的下行资源的子载波0的偏移信息(偏移单位可以是下行参考信号使用的子载波间隔、或基于下行参考信号子载波间隔的PRB等)、下行参考信号的发射功率信息(用于获取发送下行参考信号的第三网络设备到终端设备之间的下行路损)、下行参考信号所在载波的PCID信息、下行参考信号和SUL资源的频域偏差导致的路损调整量信息。可选的，下行参考信号的配置信息也可用于指示一个下行载波的位置信息、带宽信息、参考信号发送功率、下行载波的PCID信息、下行载波和SUL资源的频域偏差导致的路损调整量信息等。
其中，下行参考信号的绝对频点号可以类似于LTE中指示绝对频点号(absolute radio frequency channel number，EARFCN)的字段，即：演进陆地通用无线接入网(evolved universal terrestrial radio access network，EUTRAN)中用于指示EARFCN的字段。其中LTE上行资源的EARFCN计算可以规则如下(单位：兆赫兹MHz)：FUL＝FUL_low+0.1(NUL–NOffs-UL)，其中NUL为LTE上行资源的EARFCN，FUL为LTE上行资源的中心频点，FUL_low代表上行频段的最低频率，0.1为LTE载波上下行资源的栅格大小100kHz，NOffs-UL为LTE载波上行资源所述的频段的最低频率对应的EARFCN，具体参数可以参见表1所示。其中EARFCN的计算与NR频段的定义和频段内上下行资源栅格大小的定义相关联。当然，下行参考信号的绝对频点号还可以通过其它方式计算，本申请实施例中对此并不作限制。

在物理上，本申请实施例中涉及NR DL(如非SUL资源)的下行发射和NR UL(如非SUL资源)的上行接收的网络设备为第一网络设备；本申请实施例中涉及NR SUL的上行接收的网络设备为第二网络设备。若第一网络设备和第二网络设备相同， 则为共站；若不同则为跨站(或非共站)。本申请实施例中不限制第一网络设备和第二网络设备在物理上是否相同。
可选地，在逻辑上，若NR DL的下行发射、NR UL的上行接收和NR SUL的上行接收均为一个网络设备(即第一网络设备与第二网络设备在逻辑上是同一个网络设备)，即NR DL的下行发射、NR UL的上行接收和NR SUL的上行接收对应于一个小区。
在物理上，本申请实施例中涉及的第三网络设备和第二网络设备在物理上共站，在逻辑上是不同的网络设备。
本申请实施例中涉及的接入优先级信息用于指示至少一个第一SUL资源的接入优先级顺序。
本申请实施例中涉及的参考信号(reference signal，RS)可以包括但不限于：CSI-RS和CRS。
本申请实施例中涉及的SUL资源(例如第一SUL资源、第二SUL资源和/或第三SUL资源等)可以是和LTE载波中的上行资源共享的同一频域资源，或没有NR的下行传输仅有NR的上行传输的频域资源。其中，没有NR的下行传输仅有NR的上行传输的频域资源还可以称为NR的SUL资源或NR的SUL载波。
本申请实施例中涉及的上行资源可以理解为载波(包括非载波聚合(carrier aggregation，CA)场景中的载波和CA场景中的载波)用于上行传输的部分，或服务小区(包括CA场景中的服务小区和非CA场景中的服务小区)用于上行传输的部分。其中，CA场景中的载波(服务小区)可以为主载波(主小区)或辅载波(辅小区)。上行资源也可以称为上行载波。相应的，载波或服务小区用于下行传输的部分可以理解为下行资源或下行载波。例如，在频分双工(frequency division duplex，FDD)系统中，载波中用于上行传输的频率资源可以理解为该上行资源或上行载波；用于下行传输的频率资源可以理解为下行资源或下行载波。再如，在时分双工(time division duplex，TDD)系统中，载波中用于上行传输的时域资源可以理解为上行资源或上行载波；用于下行传输的时域资源可以理解为下行资源或下行载波。
可选地，一个NR上行资源、一个NR下行资源和一个NR的SUL资源可以是一个NR载波资源(服务小区)。进一步的，一个NR上行资源、一个NR下行资源和多个NR的SUL资源也可以是一个NR载波资源(服务小区)。
在如图1A所示的LTE-NR共站部署的无线通信场景中，NR UE2根据从网络设备1接收的下行测量值大于SSB选择门限的至少一个SSB中随机选择目标SSB。若目标SSB的参考信号接收功率(reference signal received power，RSRP)大于或等于SUL-RSRP-阈值，则选择NR载波中的上行资源(即非SUL资源)进行随机接入；若目标SSB的RSRP小于SUL-RSRP-阈值，则选择LTE载波中的上行资源(即SUL资源)进行随机接入。
在如图1B所示的LTE-NR非共站部署的无线通信场景中和/或如图1C所示的LTE-NR共站部署的无线通信场景中，NR终端如何选择NR载波中的上行资源(即非SUL资源)或者至少一个LTE载波中的上行资源(即多个SUL资源)中的一个资源进行随机接入以提升通信系统的随机接入效率成为亟待解决的问题。
本申请实施例提供的随机接入方法及装置，终端设备可以通过根据网络设备发送的 SUL配置信息确定出第一SSB对应的至少一个SUL资源和至少一个SUL选择门限，并根据第一SSB的下行测量值以及对应的SUL选择门限确定用于进行随机接入的载波资源，从而在确定的载波资源进行随机接入；其中，载波资源包括：至少一个第一SUL资源中的一个第一SUL资源，或者第一SSB对应的非SUL资源。可见，本申请实施例中实现了从非SUL资源和至少一个SUL资源中选择合适的资源进行随机接入，从而提升了通信系统的随机接入效率。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。

本步骤中，终端设备(支持上行共享的NR终端)接收第一网络设备发送的SUL配置信息。可选地，SUL配置信息中可以包括第一SSB对应的至少一个第一增补上行SUL资源和至少一个SUL选择门限。其中，第一SUL资源可以是和LTE载波中的上行资源共享的同一频域资源，或没有NR的下行传输仅有NR的上行传输(因此该频域资源又作为NR的SUL资源或NR的SUL载波)的频域资源，可以用于终端设备进行上行传输；SUL选择门限用于终端设备确定是否选择第一SUL资源进行上行传输。
示例性地，SUL配置信息中可以包括第一SSB对应的一个第一SUL资源和一个SUL选择门限、SUL配置信息中可以包括第一SSB对应的多个第一SUL资源和1个SUL选择门限(或者多个相同的SUL选择门限)，或者SUL配置信息中可以包括第一SSB对应的多个第一SUL资源和多个SUL选择门限(其中，多个第一SUL资源对应不同的SUL选择门限，或者多个第一SUL资源中的部分第一SUL资源可以对应相同的SUL选择门限)。
当然，SUL配置信息还可以包括其它信息(例如至少一个第一SUL资源对应的下行参考信号的配置信息、至少一个第一SUL资源对应的接入优先级信息，和/或至少一个第一SUL资源的上行资源配置信息等)，本申请实施例中对此并不作限制。可选地，第一SUL资源的上行资源配置信息可以包括但不限于：第一SUL资源的频域信息和公共配置信息。具体的，第一SUL资源的频域信息可以参考上述实施例中关于上行资源的频域信息的相关内容，此处不再赘述；和/或第一SUL资源的公共配置信息可以参考上述实施例中关于上行资源的公共配置信息的相关内容，此处不再赘述。
可选地，SUL配置信息中还可以包括其它SSB对应的SUL资源和SUL选择门限；或者，如果上述SUL配置信息中仅包括第一SSB对应的SUL资源和SUL选择门限，则终端设备还可以接收第一网络设备或者其它网络设备发送的其它SSB对应的SUL配置信息，本申请实施例中对此并不作限制。
可选地，本申请实施例中涉及的SUL配置信息可以携带于SIB或者RMSI中；当然还可以携带于其它消息中，本申请实施例中对此并不作限制。
需要说明的是，本申请实施例中涉及的SUL配置信息还可以称之为资源配置信息或者其它名称，本申请实施例中对此并不作限制。
需要说明的是，如果可以预先配置第一SSB对应的SUL选择门限或如果其他消息中携带了一个小区级的SUL选择门限(即小区的多个SSB都使用该SUL选择门限)，则本申请实施例中涉及的SUL配置信息中可以不包括第一SSB对应的至少一个SUL选择门限，或者本申请实施例中涉及的SUL配置信息中仍然可以包括第一SSB对应的至少一个SUL选择门限，但以SUL配置信息中携带的SUL选择门限为准。

如果第一SSB对应多个第一SUL资源的索引，可选地，SUL配置信息中还可以包括第一SSB对应的至少一个SUL选择门限。示例性地，若SUL配置信息中包括第一SSB对应的一个SUL选择门限，则代表第一SSB对应的多个第一SUL资源共用一个SUL选择门限；若SUL配置信息中包括第一SSB对应的多个SUL选择门限，则需要分别指示多个SUL选择门限所对应的至少一个第一SUL资源，或指示多个第一SUL资源对应的一个SUL选择门限。若至少一个第一SUL资源所对应的SUL选择门限均不相同，则一个第一SUL资源对应一个SUL选择门限；若多个第一SUL资源对应的SUL选择门限相同，则多个第一SUL资源公用同一个SUL选择门限。
如果第一SSB对应多个第一SUL资源的索引，可选地，SUL配置信息中还可以包括接入优先级信息。示例性地，第一SSB对应的多个第一SUL资源的索引位于SUL配置信息中的前后顺序可以用于指示第一SSB对应的多个第一SUL资源的接入优先级顺序(例如，SUL配置信息中依次包括SUL资源3的索引、SUL资源1的索引和SUL资源2的索引，则SUL资源3的接入优先级高于SUL资源1的接入优先级，SUL资源1的接入优先级高于SUL资源2的接入优先级)。当然，SUL配置信息中还可以 包括其它形式的接入优先级信息(用于指示第一SSB对应的多个第一SUL资源的接入优先级顺序)，本申请实施例中对此并不作限制。
另一种可能的实现方式中，SUL配置信息可以包括：至少一个第一SUL资源的标识和至少一个第一SUL资源对应的第一SSB的标识。
如果SUL配置信息中包括一个第一SUL资源的标识，以及该第一SUL资源对应的第一SSB的标识，可选地，SUL配置信息还可以包括一个SUL选择门限。如果SUL配置信息中不包括SUL选择门限，则预先配置有SUL选择门限，或者其他消息中会携带一个小区级的SUL选择门限(即小区的多个SUL资源都使用该SUL选择门限)；如果SUL配置信息中包括SUL选择门限，则对于第一SUL资源来说则以SUL配置信息中携带的SUL选择门限为准。
如果SUL配置信息中包括多个第一SUL资源的标识，以及该多个第一SUL资源对应的第一SSB的标识，可选地，SUL配置信息还可以包括至少一个SUL选择门限。示例性地，若SUL配置信息中包括一个SUL选择门限，则代表该多个第一SUL资源共用一个SUL选择门限；若SUL配置信息中包括多个SUL选择门限，则需要分别指示多个SUL选择门限所对应的至少一个第一SUL资源，或指示多个第一SUL资源对应的一个SUL选择门限。若多个第一SUL资源所对应的SUL选择门限均不相同，则一个第一SUL资源对应一个SUL选择门限；若多个第一SUL资源对应的SUL选择门限相同，则多个第一SUL资源公用同一个SUL选择门限；若多个第一SUL资源中至少2个第一SUL资源对应的SUL选择门限相同，则该至少2个第一SUL资源公用同一个SUL选择门限。
如果SUL配置信息中包括多个第一SUL资源的标识，以及该多个第一SUL资源对应的第一SSB的标识，可选地，SUL配置信息还可以包括接入优先级信息(用于指示第一SSB对应的多个第一SUL资源的接入优先级顺序)。
若SUL配置信息中包括多个SSB对应的至少一个SUL资源，本实施例中对SUL配置信息的可实现方式进行介绍：
一种可能的实现方式中，SUL配置信息可以包括：至少两个SSB的标识和至少两个SSB对应的至少一个SUL资源的标识。可选地，上述标识可以为索引信息，或者还可以为可用于唯一指示SSB和/或第一SUL资源的其它指示信息(如第一SUL资源的频点信息和/或第一SUL资源对应的下行参考信号的配置信息，下行参考信号的配置信息可以包括但不局限于以下至少一项：下行参考信号所在载波(或所在资源)的频点信息、带宽信息、下行参考信号所在载波的PCID、下行参考信号的发射功率信息、下行参考信号和SUL资源的频域偏差导致的路损调整量信息，下行参考信号还可以理解为第一SUL资源所在频段的一个LTE下行载波，即LTE载波的频点信息、带宽信息、PCID、LTE载波和SUL资源的频域偏差导致的路损调整量信息)，本申请实施例中对此并不作限制。
如果SSB0(SUL配置信息中包括的多个SSB中的任一SSB)对应一个SUL资源的索引，可选地，SUL配置信息还可以包括一个SSB0对应的SUL选择门限。如果SUL配置信息中不包括SSB0对应的SUL选择门限，则预先配置有SUL选择门限，或者其他消息中会携带一个小区级的SUL选择门限(即小区的多个SSB都使用该SUL选 择门限)；如果SUL消息中包括SSB0对应的SUL选择门限，则对于SSB0来说则以SUL配置信息中携带的SUL选择门限为准。
如果SSB0对应多个SUL资源的索引，可选地，SUL配置信息中还可以包括SSB0对应的至少一个SUL选择门限。示例性地，若SUL配置信息中包括SSB0对应的一个SUL选择门限，则代表SSB0对应的多个SUL资源共用一个SUL选择门限；若SUL配置信息中包括SSB0对应的多个SUL选择门限，则需要分别指示多个SUL选择门限所对应的至少一个第一SUL资源，或指示多个SUL资源对应的一个SUL选择门限。若多个SUL资源所对应的SUL选择门限均不相同，则一个SUL资源对应一个SUL选择门限；若多个SUL资源对应的SUL选择门限相同，则多个SUL资源公用同一个SUL选择门限。
如果SSB0对应多个SUL资源的索引，可选地，SUL配置信息中还可以包括接入优先级信息(用于指示SSB0对应的多个SUL资源的接入优先级顺序)。示例性地，SSB0对应的多个SUL资源的索引位于SUL配置信息中的前后顺序可以用于指示SSB0对应的多个SUL资源的接入优先级顺序。当然，SUL配置信息中还可以包括其它形式的接入优先级指示信息，本申请实施例中对此并不作限制。
另一种可能的实现方式中，SUL配置信息可以包括：至少一个SUL资源的标识和至少一个SUL资源对应的至少一个SSB的标识。
如果SUL0资源(SUL配置信息中包括的多个SUL资源中的任一SUL资源)对应一个SSB的索引，可选地，SUL配置信息还可以包括一个SUL资源0对应的SUL选择门限。如果SUL配置信息中不包括SUL资源0对应的SUL选择门限，则预先配置有SUL选择门限，或者其他消息中会携带一个SUL选择门限(即SUL0资源使用该SUL选择门限)；如果SUL消息中包括SUL资源0对应的SUL选择门限，则对于SUL0资源来说则以SUL配置信息中携带的SUL选择门限为准。
如果SUL0资源对应多个SSB的索引，可选地，SUL配置信息中还可以包括SUL0资源对应的至少一个SUL选择门限。示例性地，若SUL配置信息中包括SUL0资源对应的一个SUL选择门限，则代表该多个SSB共用一个SUL选择门限；若SUL配置信息中包括SUL0资源对应的多个SUL选择门限，则需要分别指示多个SUL选择门限对应的SSB，或分别指示多个SSB对应的SUL选择门限。若多个SSB所对应的SUL选择门限均不相同，则一个SSB对应一个SUL选择门限；若多个SSB对应的SUL选择门限相同，则多个SSB公用同一个SUL选择门限。
如果SUL配置信息中包括多个SUL资源的标识，以及该多个SUL资源对应的一个SSB的索引，可选地，SUL配置信息中还可以包括至少一个SUL选择门限。示例性地，若SUL配置信息中包括一个SUL选择门限，则代表该多个SUL资源共用一个SUL选择门限；若SUL配置信息中包括多个SUL选择门限，则需要分别指示多个SUL选择门限所对应的至少一个SUL资源，或指示多个SUL资源对应的一个SUL选择门限。若多个SUL资源所对应的SUL选择门限均不相同，则一个SUL资源对应一个SUL选择门限；若多个SUL资源对应的SUL选择门限相同，则多个SUL资源公用同一个SUL选择门限。
如果SUL配置信息中包括多个SUL资源的标识，以及该多个SUL资源对应的一 个SSB的索引，可选地，SUL配置信息中还可以包括接入优先级信息(用于指示该多个SUL资源的接入优先级顺序)。
另一种可能的实现方式：SUL配置信息可以包括：一个SUL资源的标识和至少两个SUL选择门限。可选地，该SUL资源可以对应多个SSB的标识。
为了进一步指示不同SSB对应的SUL选择门限，SUL配置信息中还可以包括：多个SSB的标识与其对应的SUL选择门限。示例性地，针对水平波束可以对应一个SUL选择门限，针对垂直波束可以对应一个SUL选择门限，使得不同楼层的终端设备可以根据不同的SUL选择门限选择合适的上行载波。例如，对于高楼终端设备来说，当终端设备按照水平波束对应的SUL选择门限选择上行载波时，终端设备会在SUL资源上的RACH接入失败，因此可以设置垂直波束对应的SUL选择门限小于水平波束对应的SUL选择门限，使得终端设备根据垂直波束对应的SUL选择门限会选择在非SUL资源上发起RACH接入。
当然，SUL配置信息还可以采用其它的可实现方式，本申请实施例中对此并不作限制。
步骤S202、根据第一SSB的下行测量值以及至少一个SUL选择门限确定用于进行随机接入的载波资源。
本步骤中，终端设备根据第一SSB的下行测量值以及至少一个SUL选择门限确定用于进行随机接入的载波资源；其中，载波资源包括：第一SSB对应的至少一个第一SUL资源中的一个第一SUL资源，或者第一SSB对应的非SUL资源。
一种可能的实现方式中，如果SUL配置信息中包括第一SSB对应的一个第一SUL资源以及第一SSB对应的一个SUL选择门限(或者称之为第一SUL资源对应的SUL选择门限)，则根据第一SSB的下行测量值以及第一SSB对应的SUL选择门限确定用于进行随机接入的载波资源。
可选地，如图2B所示，如果第一SSB的下行测量值大于或等于第一SSB对应的SUL选择门限(如图2B中的SUL选择门限，SUL选择门限大于驻留门限)，则终端设备(如图2B中的UE1)确定用于进行随机接入的载波资源包括非SUL资源(如图2B中所示的3.5G载波资源)；或者，如果第一SSB的下行测量值小于第一SSB对应的SUL选择门限(如图2B中的SUL选择门限)，则终端设备(如图2B中的UE2)用于进行随机接入的载波资源包括第一SSB对应的一个第一SUL资源(如图2B中所示的1.8G SUL资源)。
另一种可能的实现方式中，如果SUL配置信息中包括第一SSB对应的N1个第一SUL资源以及第一SSB对应的一个SUL选择门限(或者称之为N1个第一SUL资源对应的SUL选择门限)，其中，N1为大于或等于2的整数，则根据第一SSB的下行测量值以及第一SSB对应的SUL选择门限确定用于进行随机接入的载波资源。
可选地，如果第一SSB的下行测量值大于或等于第一SSB对应的SUL选择门限(如图2C中的SUL选择门限，SUL选择门限大于驻留门限)，则终端设备(如图2C中的UE1)用于进行随机接入的载波资源包括非SUL资源(如图2C中所示的3.5G载波资源)；或者，如果第一SSB的下行测量值小于第一SSB对应的SUL选择门限(如图2C中的SUL选择门限)，则终端设备(如图2C中的UE2)用于进行随机接入 的载波资源包括N1个第一SUL资源中的一个SUL资源(如图2C中所示的1.8G SUL1资源或者1.8G SUL2资源)。本申请下述实施例中对终端设备从N1个第一SUL资源中确定出用于进行随机接入的载波资源的可实现方式：

当然，终端设备还可以通过其它方式从N1个第一SUL资源中确定出用于进行随机接入的载波资源，本申请实施例中对此并不作限制。
另一种可能的实现方式中，如果SUL配置信息中包括第一SSB对应的N2个第一SUL资源以及第一SSB对应的N3个SUL选择门限，其中，N2和N3为大于或等于2的整数(可选地，N2大于或等于N3)，N2个第一SUL资源中的一个第一SUL资源对应N3个SUL选择门限中的一个SUL选择门限(可选地，N2个第一SUL资源中的一个第一SUL资源可以分别对应N3个SUL选择门限中一个不同的SUL选择门限，或者N2个第一SUL资源中的多个第一SUL资源可以对应N3个SUL选择门限中一个相同的SUL选择门限)，则终端设备可以根据接入优先级信息从N2个第一SUL资源中确定第三SUL资源，其中，接入优先级信息用于指示N2个第一SUL资源的接入优先级顺序，第三SUL资源的接入优先级高于N2个第一SUL资源中除第三SUL资源之外的其它SUL资源的优先级；或者，终端设备可以根据终端设备能力(终端设备所支持的载波资源)从N2个第一SUL资源中选择出一个SUL资源作为第三SUL资源。当然，终端设备还可以通过其它方式从N2个第一SUL资源中选择出第三SUL资源，本申请实施例中对此并不作限制。
进一步地，终端设备根据第一SSB的下行测量值以及第三SUL资源对应的SUL选择门确定用于进行随机接入的载波资源；其中，载波资源包括：第三SUL资源，或者第一SSB对应的非SUL资源。可选地，如果第一SSB的下行测量值大于或等于第三SUL资源对应的SUL选择门限，则用于进行随机接入的载波资源包括非SUL资源；或者，如果第一SSB的下行测量值小于第三SUL资源对应的SUL选择门限，则用于进行随机接入的载波资源包括第三SUL资源。
另一种可能的实现方式中，如果SUL配置信息中包括第一SSB对应的N4个第一SUL资源以及第一SSB对应的N4个SUL选择门限，其中，N4为大于或等于2的整数，N4个第一SUL资源中的一个第一SUL资源对应N4个SUL选择门限中的一个SUL选择门限(即N4个第一SUL资源中的一个第一SUL资源可以分别对应N4个SUL选择门限中一个SUL选择门限，其中，不同的第一SUL资源对应的SUL选择门限可以相同，也可以不同，本申请不做限制)，则终端设备可以根据N4个SUL选择 门限中与第一SSB的下行测量值最接近的SUL选择门限，确定用于进行随机接入的载波资源。
可选地，如果第一SSB的下行测量值小于第四SUL资源对应的SUL选择门限且大于或等于第五SUL资源对应的选择门限，则用于进行随机接入的载波资源包括第四SUL资源，其中，第四SUL资源和第五SUL资源包括于N4个第一SUL资源中(可选地，第四SUL资源对应的SUL选择门限或第五SUL资源对应的SUL选择门限为N4个SUL选择门限中最小值与最大值之间的任意值)；或者，
如果第一SSB的下行测量值小于第六SUL资源对应的SUL选择门限，则用于进行随机接入的载波资源包括第六SUL资源，其中，第六SUL资源对应的SUL选择门限为N4个SUL选择门限中最小值；或者，
如果第一SSB的下行测量值大于或等于第七SUL资源对应的SUL选择门限，则用于进行随机接入的载波资源包括非SUL资源，其中，第七SUL资源对应的SUL选择门限为N4个SUL选择门限中最大值。
示例性地，“终端设备可以根据N4个SUL选择门限中与第一SSB的下行测量值最接近的SUL选择门限，确定用于进行随机接入的载波资源”还可以描述为以下方式：
终端设备可以根据N4个SUL选择门限的大小顺序，将N4个SUL选择门限划分为至少三个SUL选择门限区间。例如，假设N4等于3，且SUL选择门限1大于SUL选择门限2以及SUL选择门限2大于SUL选择门限3(一个SUL选择门限对应三个第一SUL资源中的一个第一SUL资源)，则终端设备可以将3个SUL选择门限划分为(更小值，SUL选择门限3)、[SUL选择门限3，SUL选择门限2)、[SUL选择门限2，SUL选择门限1)和[SUL选择门限1，更大值)。
进一步地，根据第一SSB的下行测量值所属的目标SUL选择门限区间，确定发起随机接入的载波资源。可选地，如果目标SUL选择门限区间中的上边界属于N4个SUL选择门限中的任一SUL选择门限，则确定用于进行随机接入的载波资源包括上边界所对应的第一SUL资源；例如，假设目标SUL选择门限为[SUL选择门限2，SUL选择门限1)，则确定用于进行随机接入的载波资源包括上边界(例如，SUL选择门限1)所对应的第一SUL资源。或者，如果目标SUL选择门限区间无上边界，则确定发起随机接入的载波资源包括非SUL资源；例如，假设目标SUL选择门限为[SUL选择门限1，更大值)，则确定发起随机接入的载波资源包括非SUL资源。
可选地，如果SUL配置信息中包括第一SSB对应的N4个第一SUL资源以及第一SSB对应的N4个SUL选择门限，其中，N4为大于或等于2的整数，N4个第一SUL资源中的一个第一SUL资源对应N4个SUL选择门限中的一个SUL选择门限，则终端设备还可以根据终端设备能力(终端设备所支持的载波资源)以及N4个SUL选择门限的部分或全部SUL选择门限中与第一SSB的下行测量值最接近的SUL选择门限，确定用于进行随机接入的载波资源。
如图2D所示，假设N4等于2，且SUL选择门限1(SUL选择门限1对应1.8G SUL1资源)大于SUL选择门限2(SUL选择门限2对应800M SUL2资源，SUL选择门限2大于驻留门限)，则终端设备可以将2个SUL选择门限划分为(更小值(即小于SUL选择门限2的值)，SUL选择门限2)、[SUL选择门限2，SUL选择门限1)和[SUL选择门限1，更大值(即大于SUL选择门限1的值))。
可选地，1)如果终端设备支持1.8G SUL1资源和800M SUL2资源，则终端设备根据第一SSB的下行测量值属于(更小值，SUL选择门限2)、[SUL选择门限2，SUL选择门限1)或[SUL选择门限1，更大值)确定发起随机接入的载波资源。若第一SSB的下行测量值属于(更小值，SUL选择门限2)，则终端设备(如图2D中的UE3)发起随机接入的载波资源包括SUL选择门限2对应800M SUL2资源。若第一SSB的下行测量值属于[SUL选择门限2，SUL选择门限1)，则终端设备(如图2D中的UE2)发起随机接入的载波资源包括1.8G SUL1资源；若第一SSB的下行测量值属于[SUL选择门限1，更大值)，则终端设备(如图2D中的UE1)发起随机接入的载波资源包括非SUL资源(如3.5G资源)。
2)如果终端设备支持1.8G SUL1资源且不支持800M SUL2资源，则终端设备根据第一SSB的下行测量值属于[SUL选择门限2，SUL选择门限1)或者[SUL选择门限1，更大值)确定发起随机接入的载波资源。若第一SSB的下行测量值属于[SUL选择门限2，SUL选择门限1)，则终端设备(如图2D中的UE2)发起随机接入的载波资源包括1.8G SUL1资源。若第一SSB的下行测量值属于[SUL选择门限1，更大值)，则终端设备(如图2D中的UE1)发起随机接入的载波资源包括非SUL资源(如3.5G资源)。
3)如果终端设备支持800M SUL2资源且不支持1.8G SUL1资源，则终端设备根据第一SSB的下行测量值属于(更小值，SUL选择门限2)或者[SUL选择门限2，更大)确定发起随机接入的载波资源。若第一SSB的下行测量值属于(更小值，SUL选择门限2)，则终端设备(如图2D中的UE3)发起随机接入的载波资源包括SUL选择门限2对应800M SUL2资源。若第一SSB的下行测量值属于[SUL选择门限2，更大)，则终端设备(如图2D中的UE1)发起随机接入的载波资源包括非SUL资源(如3.5G资源)。
当然，终端设备根据第一SSB的下行测量值以及至少一个SUL选择门限，还可通过其它可实现方式确定用于进行随机接入的载波资源，本申请实施例中对此并不作 限制。
步骤S203、在确定的载波资源进行随机接入。
本步骤中，终端设备在确定的载波资源进行随机接入，具体的随机接入过程可以参考本申请上述实施例中记载的相关内容，本申请实施例中不再赘述。
本申请实施例中，通过接收SUL配置信息，SUL配置信息中包括第一SSB对应的至少一个第一增补上行SUL资源和至少一个SUL选择门限。进一步地，可以根据第一SSB的下行测量值以及至少一个SUL选择门限确定用于进行随机接入的载波资源，并在确定的载波资源进行随机接入；其中，载波资源包括：至少一个第一SUL资源中的一个第一SUL资源，或者第一SSB对应的非SUL资源。可见，本申请实施例中实现了从非SUL资源和至少一个SUL资源中选择合适的资源进行随机接入，从而提升了LTE-NR共站部署和/或LTE-NR非共站部署通信系统的随机接入效率。
在无线通信系统中，通过功率控制使得不同终端设备到达网络设备的信号功率基本一致，从而降低彼此间的干扰，以提升系统性能。示例性地，假设终端设备在小区c或者载波c的子帧i发送PUSCH时，根据如下公式确定PUSCH的发射功率(即上行信号的发射功率)：
Figure PCTCN2019070639-appb-000002
其中，P CMAX,c(i)为终端设备在小区c或者载波c的子帧i的最大发射功率。
M PUSCH,c(i)为小区c或者载波的子帧i上网络设备分配给终端设备的RB个数。
P O_PUSCH,c为网络设备期望的接收功率；其中，P O_PUSCH,c＝P O_UE_PUSCH,c+P O_NOMINAL_PUSCH,c，P O_NOMINAL_PUSCH,c表示正常解调时网络设备期望的PUSCH的发射功率，P O_UE_PUSCH,c为终端设备相对于P O_NOMINAL_PUSCH,c的功率偏置。其中，P O_NOMINAL_PUSCH,c和P O_UE_PUSCH,c可以是网络设备通过信令为终端设备配置的，也可以是预配置的，本申请不做限制。
PL c为终端设备根据下行载波的参考信号所估计的下行路损估计值，用于确定通过上行载波(上行载波可以是SUL资源或非SUL资源)传输时的上行路损估计值。
α c为高层信令配置的路损补偿因子，取值范围为0到1。
Δ TF,c(i)为不同的调制与编码策略(modulation and coding scheme，MCS)格式相对于参考MCS格式的功率偏置值。
f c(i)为终端设备的PUSCH发射功率的调整量，由PDCCH中的发射功率控制(transmit power control，TPC)信息映射获得。
考虑到PL c与网络设备与终端设备之间的距离d和进行数据传输的载波频率fc相关，一般情况下上下行的频率间距比较近，上行路损可以近似等于下行路损，因此，终端设备可以根据网络设备广播的下行参考信号(如CRS、SSB、CSI-RS等)的发射功率与终端设备侧的接收功率估算PL c。
在如图1A所示的LTE-NR共站部署的无线通信场景中，若NR UE2使用NR载波中的下行资源与网络设备1进行下行传输且使用SUL资源(可选的，SUL资源可 以和LTE载波的上行资源共享同一频域资源，SUL资源仅用于NR进行上行传输)与网络设备1进行上行传输，虽然NR UE2到网络设备1之间的上行距离和网络设备1到NR UE2之间的下行距离相等，但上下行的频率间距比较大，因此上行路损不等于下行路损(可选地，相差一个和LTE载波频率与NR载波频率的比值相关的数值，例如20log10(LTE载波频率/NR载波频率))。可选地，通过配置P O_PUSCH,c中的P O_UE_PUSCH,c来弥补上下行路损差(例如，对于SUL资源的P O_UE_PUSCH,c与对于非SUL资源的P O_UE_PUSCH,c之间的差值为20log10(LTE载波频率/NR载波频率))，以便于终端设备仍可以使用PL c来计算SUL资源上的发射功率。
在如图1B所示的LTE-NR非共站部署的无线通信场景中，若NR UE4使用NR载波中的下行资源与网络设备2进行下行传输且使用SUL资源(可选的，SUL资源可以和LTE载波的上行资源共享同一频域资源，SUL资源仅用于NR进行上行传输)与网络设备3进行上行传输，则不仅NR UE4到网络设备2之间的上行距离和NR UE4到网络设备3之间的下行距离不相等，同时上下行的频率间距比较大，可见，终端设备根据网络设备2与NR UE4之间的PL c无法准确估计NR UE4与网络设备3之间的上行路损。因此，终端设备如何准确地估计NR UE4与网络设备3之间的上行路损(或称为终端设备在使用非共站SUL资源时如何估计上行路损以确定上行信号的发送功率)是亟待解决的问题。
图3为本申请另一实施例提供的随机接入方法的流程示意图。在上述实施例的基础上，如果在步骤S202中确定用于进行随机接入的载波资源包括：第一SSB对应的至少一个第一SUL资源中的一个第一SUL资源，本申请实施例中对根据载波资源进行随机接入时的上行发射功率的一种可实现的确定方式进行说明，该方法还可以用于确定终端设备在第一SUL资源上进行其他上行信号或者上行信道传输时的上行发射功率计算。如图3所示，本申请实施例的方法可以包括：
步骤S301、根据第一SUL资源对应的下行参考信号的配置信息接收下行参考信号。
本步骤中，终端设备(如图1B中所示的NR UE4)可以根据第一SUL资源对应的下行参考信号的配置信息在相应的下行资源接收第三网络设备(如图1B中所示的网络设备3)发送的下行参考信号。其中，下行参考信号的配置信息可以用于指示以下至少一项：下行参考信号的下行资源的位置信息、下行参考信号对应的发射功率信息，以及下行参考信号所在载波对应的PCID信息、下行参考信号和SUL资源的频域偏差导致的路损调整量信息。
步骤S302、根据下行参考信号的下行测量值确定上行发射功率，上行发射功率用于进行随机接入。
本步骤中，示例性地，终端设备可以根据下行参考信号的下行测量值以及下行参考信号的发射功率信息确定下行路损信息(如图1B中所示的网络设备3到NR UE4的下行路损信息)。考虑到网络设备3到NR UE4之间的下行距离，和NR UE4到网络设备3之间的上行距离近似相等，且网络设备3与NR UE4之间的上下行的频率间距比较近或 在一个频段时，因此，网络设备3到NR UE4的下行路损可以近似等于NR UE4到网络设备3的上行路损，终端设备根据下行参考信号的发射功率信息和所述下行参考信号的测量值确定网络设备3到NR UE4的下行路损。进一步地，终端设备可以根据下行路损信息(如PL c)确定用于进行随机接入的上行发射功率，从而根据上行发射功率向网络设备(即发送下行参考信号的网络设备，如图1B中所示的网络设备3)进行随机接入。可选地，还可根据网络设备3到NR UE4的下行路损、和下行参考信号的频率与SUL频率偏差导致的路损调整量进一步更加准确的估计终端设备NR UE4到网络设备3的上行路损；可选地，根据下行路损信息确定上行发射功率的方式可以参考本申请上述实施例中涉及的关于“确定PUSCH的发射功率”的相关内容，此处不再赘述；可选的，确定终端设备在第一SUL资源的上行发射功率方法还可以用于第一SUL资源的其他上行信号或上行信道上，如PUSCH信道、PUCCH信道、SRS信道等，本申请对此并不做限制。
可选地，下行参考信号的下行测量值可以为终端设备通过下行测量第三网络设备发送的下行参考信号(如CRS、SSB、CSI-RS等)得到的；当然下行参考信号的下行测量值还可以通过其它方式测量得到，本申请实施例中对此并不作限制。
本申请实施例中，通过根据第一SUL资源对应的下行参考信号的配置信息接收下行参考信号，并根据下行参考信号的下行测量值确定用于进行随机接入的上行发射功率，从而根据上行发射功率向用于发送下行参考信号的网络设备进行随机接入。可见，本申请实施例中，通过随机接入的目标网络设备或目标网络设备指定的第三网络设备所发送的下行参考信号的下行测量值确定上行发射功率，从而可以准确地确定出上行发射功率，进一步提高了通信系统的随机接入效率，还降低了小区间干扰。
图2A和图3涉及的方法可以结合使用，可以独立使用，本申请不做限制。
图4为本申请另一实施例提供的随机接入方法的流程示意图。在上述实施例的基础上，本申请实施例对网络设备侧进行介绍。如图4所示，本申请实施例的方法可以包括：

本申请实施例中，通过网络设备发送SUL配置信息(包括第一SSB对应的至少一个第一SUL资源和至少一个SUL选择门限)，以便终端设备根据第一SSB的下行测量值以及SUL配置信息中的至少一个SUL选择门限确定用于进行随机接入的载波资源，并在确定的载波资源进行随机接入；其中，载波资源包括：至少一个第一SUL资源中的一个第一SUL资源，或第一SSB对应的非SUL资源。进一步地，网络设备在确定的载波资源接收终端设备发送的随机接入前导。可见，本申请实施例中实现了终端设备可以从非SUL资源和至少一个SUL资源中选择合适的资源进行随机接入，从而提升了LTE-NR共站部署和/或LTE-NR非共站部署通信系统的随机接入效率。

本步骤中，终端设备从接收到的多个SSB中选择出第一SSB(如SSB5)，并根据SSB5的下行测量值与SUL配置信息中携带的SUL选择门限(或者预设的SUL选择门限)确定用于进行随机接入的载波资源。示例性地，若SSB5的下行测量值小于SUL选择门限，则确定用于进行随机接入的载波资源包括SSB5对应的SUL2资源；若SSB5的下行测量值大于或等于SUL选择门限，则确定用于进行随机接入的载波资源包括非SUL资源。
可选地，若根据SUL2资源进行随机接入过程中的随机接入前导码的功率达到最大预设阈值或者传输次数达到SUL2资源随机接入前导码的最大预设传输次数，则可以重新确定用于进行随机接入的载波资源包括SSB5对应的SUL1资源，而不是放弃随机接入以进行小区重选。

本申请另一实施例提供的随机接入方法中，针对如图1C所示的LTE-NR共站部署的无线通信场景中，终端设备如何选择合适的载波资源进行随机接入的可实现方式进行说明。可选地，本申请实施例的方法可以包括：
步骤S701、终端设备接收SUL配置信息，SUL配置信息中可以包括至少一个SUL资源、至少一个SUL资源对应的小区和选择门限。
本步骤中，终端设备接收网络设备发送的SUL配置信息。可选地，SUL配置信息中可以包括至少一个SUL资源、至少一个SUL资源对应的小区和选择门限；当然，SUL配置信息还可以包括其它信息，本申请实施例中对此并不作限制。
示例性地，若SUL配置信息中包括至少两个SUL资源，则至少两个SUL资源可以对应一个相同的选择门限，或者至少两个SUL资源可以对应多个选择门限(例如，至少两个SUL资源对应不同的选择门限，或者至少两个SUL资源中的部分SUL资源可以对应相 同的选择门限)。
示例性地，一个SUL资源可以对应至少一个小区(如NR小区)。可选地，当一个SUL资源和一个小区(例如第一小区)对应时，则SUL配置信息中可以不包含其它小区的相关信息；当一个SUL资源和两个小区(例如第一小区和第二小区)对应时，则SUL配置信息中还包括第二小区的相关信息。例如，NR小区1(对应第一小区)中的SUL配置信息中可以包括SUL1资源的配置信息(例如包括SUL1资源对应的小区和/或选择门限等)和SUL2资源的配置信息(例如包括SUL2资源对应的小区和/或选择门限等)。其中，NR小区1关联的SUL1资源不与NR小区2关联；NR小区1关联的SUL2资源与NR小区2关联，此时SUL2资源的配置信息中还可以包括NR小区2(对应第二小区)的相关信息。可选地，NR小区2的相关信息可以包括但不限于：NR小区2的参考信号信息(例如，NR小区2的SSB频域位置、物理小区ID、SSB的发送功率，和/或NR小区2对应的选择门限等)。
可选地，本申请实施例中涉及的SUL配置信息可以携带于SIB或者RMSI中；当然还可以携带于其它消息中，本申请实施例中对此并不作限制。
步骤S702、终端设备根据本小区的下行测量值和邻小区的下行测量值，确定用于进行随机接入的载波资源。
本步骤中，终端设备根据本小区(例如NR小区1)的下行测量值和邻小区(例如NR小区2)的下行测量值，确定用于进行随机接入的载波资源；其中，载波资源包括：本小区对应的一个SUL资源、邻小区对应的一个SUL资源，或者本小区对应的非SUL资源。可选地，下行测量值可以为参考信号接收功率(Reference Signal Receiving Power，RSRP)；当然还可以为其它下行测量结果，本申请实施例中对此并不作限制。
可选地，若本小区(例如NR小区1)的下行测量值低于本小区对应的选择门限，且邻小区(例如NR小区2)的下行测量值低于邻小区对应的选择门限，则确定用于进行随机接入的载波资源包括本小区(例如NR小区1)对应的一个SUL资源(例如SUL1资源)。
可选地，若本小区(例如NR小区1)的下行测量值低于本小区对应的选择门限，且邻小区(例如NR小区2)的下行测量值高于邻小区对应的选择门限，则确定用于进行随机接入的载波资源包括邻小区(例如NR小区2)对应的一个SUL资源(例如SUL2资源)。
可选地，若本小区(例如NR小区1)的下行测量值高于本小区对应的选择门限，则确定用于进行随机接入的载波资源包括本小区对应的非SUL资源。
步骤S703、终端设备在确定的载波资源进行随机接入。
本步骤中，终端设备在确定的载波资源进行随机接入，具体的随机接入过程可以参考本申请上述实施例中记载的相关内容，本申请实施例中不再赘述。
本申请实施例中，终端设备通过接收SUL配置信息，SUL配置信息中可以包括至少一个SUL资源、至少一个SUL资源对应的小区和选择门限。进一步地，终端设备根据本小区的下行测量值和邻小区的下行测量值，确定用于进行随机接入的载波资源，并在确定的载波资源进行随机接入；其中，载波资源包括：本小区对应的一个SUL资源、邻小区对应的一个SUL资源，或者本小区对应的非SUL资源。可见，本申请实施例中 实现了在LTE和NR覆盖未对齐的无线通信场景中终端设备仍然可以选择合适的载波资源进行随机接入，从而提升了通信系统的随机接入效率。
随着终端设备的用户不断增长，用户业务量和数据吞吐量不断增加，频谱资源的需求也日益增加。然而，无线频谱资源短缺，很难找到连续的大带宽资源供移动通信使用，因此，引入了CA技术，即把多个连续或不连续的频谱资源(例如，载波)聚合使用，以满足移动通信对于大带宽的需求，同时也提高了零散频谱的利用率。
目前，在CA技术中，终端设备可以支持多个载波的聚合。在多个服务小区进行载波聚合时，终端设备通常配置一个主小区或主载波，主载波的上行载波上配置了PUCCH资源，用于用户联合反馈聚合的一个服务小区或多个服务小区的下行数据的ACK/NACK。当聚合的服务小区过多，主载波或主小区的上行载波的PUCCH资源需要反馈的确认字符(Acknowledgement，ACK)/非确认字符(Negative-Acknowledgement，NACK)比特数较多，会造成主载波的PUCCH资源拥塞，从而CA技术中引入了两个PUCCH小区组(如主PUCCH小区组和辅PUCCH小区组)；其中，一个PUCCH小区组中包含一个PUCCH资源，用于反馈该小区组中的下行数据的ACK/NACK。可选地，载波聚合的多个载波或服务小区中，至多有两个服务小区的上行载波配置了PUCCH资源，一个是主PUCCH小区组中的主小区或主载波的上行载波，另一个是辅PUCCH小区组中的一个辅载波或辅小区的上行载波。
对于包含SUL资源的服务小区来说，SUL资源的主要目的是为了提升终端设备的上行覆盖，此外为了提升用户的吞吐量，所以可以为终端设备配置多个载波，通过载波聚合的技术提升用户的吞吐量。
示例性地，终端设备配置的包含SUL资源的服务小区可以是PUCCH小区组(如主PUCCH小区组和/或辅PUCCH小区组)中包含PUCCH资源的服务小区。
示例性地，包含SUL资源的服务小区可以属于SUL资源或非SUL资源中的一个载波(用于终端设备传输PUCCH资源)上。
当然，包含SUL资源的服务小区还可以属于其它服务小区或载波资源上，本申请实施例中对此并不作限制。
