本申请主张在2023年04月14日在中国提交的中国专利申请No.202310406234.5的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种信息传输方法、装置及通信设备。
背景技术
相关技术中，对于高速移动场景，为了降低切换时延，引入了早期随机接入信道(early RACH)方案，即网络可以通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)命令(order)使用户设备(User Equipment，UE)在小区切换之前获取目标小区的定时提前(Time Advance，TA)值。为了支持触发邻区的随机接入信道(Random Access Channel，RACH)，相关技术中可利用PDCCH order中的保留比特指示目标小区的标识。但对于目标小区的TA值在小区切换之前还是小区切换时告知UE，目前达成结论是取决于无线资源控制(Radio Resource Control，RRC)配置。对于在小区切换时将TA值告知UE的情况，即网络不反馈随机接入响应(Random Access Response，RAR)，UE无法得知前导码(Preamble)是否传输正确，RACH进程是否成功完成。另外，为了提高物理随机接入信道(Physical Random Access Channel，PRACH)传输的可靠性，提出了PRACH重传方案。但PRACH重传会增加资源开销大，因此如何降低资源开销需要进一步优化。

为使本领域技术人员能够更好地理解本申请实施例，先进行如下说明。
1、基于无线资源控制(Radio Resource Control，RRC)的小区切换流程；
(1)测量上报：终端通过测量当前服务小区和邻小区的参考信号(Reference Signal，RS)(例如，同步信号/物理广播信道信号块(Synchronization Signal and PBCH block，SSB)和CSI参考信号(CSI Reference Signal，CSI-RS))获取小区质量，并进行上报；
(2)切换准备：网络侧根据终端侧的上报小区质量，判断是否需要进行小区切换；
(3)切换命令：若网络侧判断需要进行小区切换，则发送切换请求命令至目标小区；目标小区将RRC重配信令反馈至源小区；
(4)终端重配：源小区将目标小区的RRC配置信息发送至终端，终端接收到目标小区的配置信令后，进行RRC重配；
(5)下行同步以及自动增益控制(Automatic Gain Control，AGC)调整：终端根据RRC重配后的目标小区的第一个SSB，解物理广播信道(Physical broadcast channel，PBCH)的解调参考信号(Demodulation Reference Signal，DMRS)和PBCH，获取系统帧号、半帧指示以及SSB索引(index)，进行帧级、时隙级以及符号级的下行同步，并根据SSB的接收功率调整自动增益控制AGC参数；
(6)上行同步：在下行同步后，终端通过随机接入信道(Random Access Channel，RACH)进行上行同步，直至收到随机接收响应(Random Access Response，RAR)获取定时提前(Time Advance，TA)值后，上行同步完成；
(7)切换完成：在上述步骤完成后，源小区向目标小区发送小区切换完成指示
根据上述流程可知，对于源小区和目标小区非同步的场景，从终端接收到切换信令RRC重配置(reconfiguration)到上行同步，获取TA的最长时间大约需要71ms，延迟较大。
对于源小区和目标小区同步的场景，即RACH-less based小区切换，终端在接收到RRC切换信令后，通过监听(monitor)SSB调整AGC参数，并基于源小区的TA值向目标小区发送上行信息，在收到目标小区的小区无线网络临时标识(Cell RNTI，C-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)后，则认为切换成功。由此可见， 在RACH-less的切换过程中，终端认为目标小区的TA值和源小区是相同的。
2、随机接入；
随机接入分为两类，4步(4-step)随机接入和2步(2-step)随机接入，两种类型都支持基于竞争的随机接入(Contention-Based Random Access,CBRA)和非竞争随机接入(Contention-Free Random Access，CFRA)，其中，4-step的CBRA流程如下：
(1)UE通过物理随机接入信道(Physical random-access channel，PRACH)向gNB发送Msg1，包含前导码(preamble)；
(2)UE在配置的时间窗内监听网络发送的MSG2，即RAR；
(3)UE接收到RAR后，使用网络分配的上行资源发送MSG3；
(4)UE监听MSG4(Contention Resolution)，如果竞争解决失败，UE回退到MSG1传输；
4-step的CFRA流程如下：
(1)UE向gNB发送MSG1，包含网络分配的特定preamble；
(2)UE监听到网络发送的随机接入RNTI(Random Access RNTI，RA-RNTI)加扰的MSG2，即RAR，随机接入过程结束。
RACH的触发方式有两种，一种是UE触发，另一种是网络触发。其中，网络触发的一种方式是PDCCH order触发RACH(CFRA或CBRA)以解决上行失步、辅小区的上行同步等问题。PDCCH order中包括了前导码索引(Preamble index)、SSB索引(SSB index)、前导码掩码索引(Preamble Mask index)等信息，用于指示UE发送Preamble对应的随机接入时机(RACH Occasion，RO)。终端在发送Preamble之后，基站根据接收到所述Preamble的PRACH资源，计算得出RA-RNTI，并将随机接入响应通过RA-RNTI加扰的PDCCH反馈至UE。UE在发送Preamble之后开启一个检测窗口用于检测RAR，若UE在窗口(window)内未收到RAR，则会再在一段时间后的最近的所述SSB关联的RO发送对应的Preamble，为了提高传输的可靠性，Preamble的发送功率可以逐次递增，UE重复发送Preamble操作会持续进行，直至UE收到了RAR或者Preamble的传输次数到达上限。
对于高速移动场景，为了降低切换时延，R18移动性(Mobility)引入了early RACH方案，即网络可以通过PDCCH order使UE在小区切换之前获取目标小区的TA值。为了支持触发邻区的RACH，相关技术中可利用PDCCH order中的保留比特指示目标小区的标识。但对于目标小区的TA值在小区切换之前还是小区切换时告知UE，目前达成结论是取决于RRC配置。对于目标小区的TA值是通过目标小区还是源小区告知尚在讨论。基于目前的讨论进展，early RACH方案还存在以下不足：
对于在小区切换时才将TA值告知UE的情况，即网络不反馈RAR，UE无法得知Preamble是否传输正确，RACH进程是否成功。此外，如何提高Preamble传输的可靠性需要进一步解决。对此，相关方案中通过PRACH的重传以提高传输的可靠性。但对于PRACH重传会导致资源开销大，因此如何降低资源开销需要进一步优化。
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信息传输方法进行 详细地说明。
如图2所示，本申请实施例提供了一种信息传输方法，包括：
步骤201：终端根据第一信令开始与至少一个第一对象进行物理随机接入信道PRACH传输。
可选地，终端接收源小区(如源分布单元(Distributed Unit，DU))发送的第一信令。
可选地，第一对象包括发送接收节点(Transmission Reception Point，TRP)、小区、小区组和频点中的至少一个。该第一对象也可描述成目标小区。当前服务对象为所述终端的主小区或者主辅小区。
上述PRACH传输具体是指Msg1传输。
步骤202：所述终端在满足第一条件的情况下，停止与第二对象进行PRACH传输，所述第二对象为所述至少一个第一对象中的至少一个对象，且所述第一对象与所述终端的当前服务对象不同；
其中，所述第一条件包括以下至少一项：
第一项：与所述第二对象进行的PRACH传输的传输次数大于或等于网络配置或指示的最大传输次数；
第二项：在第一时间窗内接收到第二信令，所述第二信令用于指示所述第二对象成功接收所述PRACH传输；
第三项：在第二时间窗内未接收到第三信令，所述第三信令用于指示终端开始与第三对象进行PRACH传输，所述第三对象与所述第二对象相同；这里，未在第二时间窗内接收到第三信令指示开始与所述第二对象进行PRACH传输，表明第二对象的PRACH传输已成功被第二对象接收，无需再次进行，因此，可以停止与第二对象进行PRACH传输；
第四项：在第三时间窗内接收到第四信令，所述第四信令用于指示终端开始与第四对象进行PRACH传输，所述第四对象与所述第二对象不同。这里，终端可以与多个小区进行PRACH传输，终端在成功完成一个小区的PRACH传输后，进行下一个小区的PRACH传输。若接收到第四信令指示终端开始与第四对象进行PRACH传输，则表明已经成功完成与第二对象的PRACH传输(即第二对象已成功接收PRACH传输)，因此，可以停止与第二对象进行PRACH传输。
本申请实施例中，上述第一时间窗、第二时间窗和第三时间窗均是所述终端在所述PRACH传输后启动的时间窗。该第一时间窗、第二时间窗和第三时间窗的时长可以是网络配置或协议约定的。其中一种情况是所述时间窗时长根据所述终端收到所述第二信令，或第三信令，或第四信令的时间确定。以第二信令为例，所述终端在发送PRACH后，开启第一时间窗，即开始检测所述第二信令，直至所述UE检测到所述第二信令时所述第一时间窗结束。在所述第一时间窗内，所述终端可根据网络配置或者指示的PRACH资源向至少一个第一对象发送Msg1，可选地，在所述UE向所述至少一个第一对象发送Msg1时所述UE不能检测所述第二信令。
在一个实施例中，在满足上述第一项条件的情况下，无论上述第二项、第三项和第四项 条件是否满足均停止与第二对象进行PRACH传输；或者，在满足上述第二项、第三项和第四项条件中任意一条条件的情况下，无论第一项条件是否满足，均停止与第二对象进行PRACH传输。
本申请实施例中，终端根据第一信令开始与至少一个第一对象进行物理随机接入信道PRACH传输；终端在满足第一条件的情况下，停止与第二对象进行PRACH传输，所述第二对象为所述至少一个第一对象中的至少一个对象，且所述第一对象与所述终端的当前服务对象不同；其中，所述第一条件包括以下至少一项：与所述第二对象进行的PRACH传输的传输次数大于或等于网络配置或指示的最大传输次数；在第一时间窗内接收到第二信令，所述第二信令用于指示所述第二对象成功接收所述PRACH传输；在第二时间窗内未接收到第三信令，所述第三信令用于指示终端开始与第三对象进行PRACH传输，所述第三对象与所述第二对象相同；在第三时间窗内接收到第四信令，所述第四信令用于指示终端开始与第四对象进行PRACH传输，所述第四对象与所述第二对象不同。通过上述方案，在满足第一条件的情况下，停止与第二对象进行PRACH传输，在保证了PRACH传输的完整性和可靠性的同时，降低了PRACH的资源开销。
可选地，所述第一信令包括以下至少一项：
所述至少一个第一对象的对象标识；
所述至少一个第一对象的配置信息的标识；
至少一个前导码索引(Preamble index)；
至少一个参考信号索引，例如，SSB索引或CSI-RS索引；

所述终端在所述至少一个第一对象下的身份标识，例如，C-RNTI；

本申请实施例中，上述第一信令可具体为PDCCH order，通过该第一信令触发终端开始与至少一个第一对象进行物理随机接入信道PRACH传输。
下面对PDCCH order中携带的内容与对应的UE行为进行如下说明。
在本申请的一实施例中，PDCCH order中指示K个目标小区标识，M个Preamble index，N个RS index，P个RA-RNTI，Q个Msg1的发送功率指示信息中的至少一个；其中K、M、N、P、Q的值大于或等于1，PDCCH order中携带不同指示信息的情况下，UE对应的行为如表1所示。
