Description

信息发送方法、接收方法及设备
相关申请的交叉引用
本申请基于申请号为202010568297.7、申请日为2020年06月19日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及移动通信技术领域，具体涉及一种信息发送方法、接收方法及设备。
背景技术
对于工作在免许可频段的终端(User Equipment，UE)和基站，在每次发数据之前都要进行先听后说(Listen Before Talk，LBT)操作，如果监听到信道繁忙，则退避一段时间再监听，直到信道空闲一段时间后才可认为信道空闲，再发送数据。为了减少随机接入的时延，可以将相关技术中的4步随机接入(英文可以表示为4-step RACH)机制的步骤减少到2步，从而减少进行LBT的次数，实现减少随机接入的整体时延。图1和图2分别给出了相关技术的基于竞争的4步随机接入过程和基于竞争的2步随机接入(英文可以表示为2-step RACH)过程的示意图。可以看出，2步随机接入过程发送消息A(msg A)和消息B(msg B)，可以减少基站和终端间的交互次数。
由于2步随机接入具有步骤少，时延短的优点，其应用场景也被扩展到了许可频段。也就是说，免许可频段和许可频段都可能使用2步随机接入过程。而终端发起2步随机接入时通常并未与网络建立连接，或处于暂时的连接中断状态，此时网络侧不了解发起随机接入时的终端状态等信息，因此也难以合理的配置随机接入的相关参数。

图3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301和网络设备302。其中，终端301也可以称作用户终端或用户设备(UE)，终端301可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端301的具体类型。网络设备302可以是基站和/或核心网网元，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，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。
基站可在基站控制器的控制下与终端301通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端301进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基 站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端301到网络设备302)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络设备302到终端301)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
相关技术中，在免许可频段和许可频段都可能使用2步随机接入。通常终端发起2步随机接入时并未与网络建立连接，或处于暂时的连接中断状态，所以网络侧不了解终端的随机接入的性能情况，因此，难以合理的配置随机接入的相关参数。如果终端把这些随机接入相关的信息记录下来并报给网络，则可以帮助网络侧在对应的应用场景下配置合理的2步随机接入的参数。
例如，如对于空闲态(英文可以表示为idle)或非激活态(英文可以表示为inactive)的UE，其两步随机接入的流程及上报的内容都是一致的。如果发送的msg A的内容和大小不一致，则网络侧可以区分UE发起的两步随机接入是从idle态还是inactive态发起，从而可以帮助网络进行一步的优化接入过程。例如，inactive态UE恢复(resume)的过程通常需要快速完成，网络侧可以在资源有限的情况下特别优化resume过程的2步随机接入流程。此外，有些2步(英文可以表示为2-step)随机接入信道(Random Access Channel，RACH)的资源与4步(英文可以表示为4-step)RACH共享，网络侧可根据UE上报的信息判断是否继续共享，以及多大程度的共享。
为了解决以上问题中的至少一种，本申请实施例提供了一种信息发送方法，通过终端记录并上报2步随机接入过程中的相关信息，可以帮助网络侧配置合理的随机接入相关参数，改善通信系统性能。

本申请实施例中，还可以由网络配置终端需要记录的信息，具体地，终端可以接收网络发送的配置信息，根据所述配置信息，配置所述终端需要记录的所述2步随机接入相关的信息。作为另一种实现方式，还可以是预先约定所需记录的信息，例如，在终端本地预存某种配置信息，这样，终端可以根据本地预存信息，配置所述终端需要记录的所述2步随机接入相关的信息。
以上从终端侧对本申请实施例的信息发送方法进行了描述，下面将从网络侧介绍本申请实施例的实现。

c)网络侧给所述终端配置的消息A的PUSCH资源信息，如资源的大小和位置等信息。另外，这里还可以包括所述终端发起2步随机接入时发送的消息A的大小、消息A或者PUSCH的payload大小、消息A或者PUSCH的padding大小等。
d)所述终端发起2步随机接入时参考信号质量是否高于网络配置的门限。
这里，所述参考信号包括SSB和CSI-RS。所述网络配置的门限为：msgA-RSRP-ThresholdSSB、msgA-RSRP-ThresholdSSB-SUL、msgA-RSRP-ThresholdCSI-RS、或msgA-RSRP-ThresholdCSI-RS-SUL等。
e)所述终端发起的2步随机接入和4步随机接入是否共用随机接入资源。
f)在所述终端发起的2步随机接入和4步随机接入共用随机接入资源时，所述共用的随机接入资源的资源信息。
这里，终端发起2步随机接入时使用的随机接入资源(具体可以包括PRACH机会中的RO，preamble码等)，是否与4步随机接入共用的。具体的共用的随机接入资源，可以包括：每个SSB上共用的RO或preamble码等。
g)2步随机接入映射到每个PRACH机会的SSB数目。
h)所述终端发起2步随机接入时发送的消息A的发送参数，所述发送参数包括频域起始位置、子载波间隔(在终端仅配置了2步随机接入的BWP时)、一个时间单位内频分复用的PRACH发送机会的个数、转换到4步随机接入前最多可发送的消息A的数目、msgA-PRACH-ConfigurationIndex、msgA-RO-FrequencyStart中的至少一种。
i)所述终端是否配置了msgA-PRACH-RootSequenceIndex。
j)字段ra-Prioritization是否应用于接入标识。
k)声明失败之前最多允许发送的前导码数，如，声明随机接入失败之前最多允许发送的前导码随机。
l)网络侧配置的接收消息B的时间窗口长度。
通过以上步骤，网络侧设备可以接收到所述2步随机接入相关的信息，从而能够了解终端发起2步随机接入过程时的信息，进而为后续优化随机接入相关参数的配置提供了参考信息。
在一实施例中，在上述步骤501之前，网络侧设备还可以向终端发送配置信息，配置所述终端需要记录的所述2步随机接入相关的信息。
在上述步骤501中，网络侧设备可以接收所述终端主动发送的所述2 步随机接入相关的信息，或者，网络侧设备还可以向所述终端发送请求消息，接收所述终端根据所述请求消息发送的所述2步随机接入相关的信息。
在一实施例中，在发送所述请求消息之前，网络侧设备还可以接收所述终端发送的所述终端记录有2步随机接入相关日志的指示信息，根据所述日志的指示信息，确定是否需要请求终端记录的所述2步随机接入相关的信息，并在需要时，向所述终端发送上述请求消息。
在一实施例中，如图5所示，在上述步骤501之后，网络侧设备还可以执行步骤502，根据所述2步随机接入相关的信息，进行网络覆盖及随机接入过程参数的优化处理。例如：
1)根据上述信息h、i、j、l中的至少一种，确定接入成功或失败的2步随机接入过程的频域位置、采用的前导码序列以及消息B的等待时间等信息，然后根据上述确定的信息，对相关参数进行优化配置。例如，如果预设统计时间周期内的发生接入失败的终端数量超过某个预设门限，则可以对上述频域位置、前导码序列和等待时间等进行重新配置。
2)针对非激活态和空闲态的UE，结合上述信息a和c，为非激活态和空闲态的终端配置不同的2步随机接入参数，例如，可在RACH资源有限的情况下给inactive的UE多分配2步随机接入的资源，降低inactive UE的2步随机接入的时延，使得inactive UE尽快进入连接态。
3)针对RACH发起的场景，结合上述信息b、c、h、i、j和l中的至少一种，对该场景下的RACH资源进行针对性的优化。例如，当2步随机接入失败发生在条件切换的场景下，网络侧可对条件切换的2步随机接入的条件切换的发起门限、等待msg B的时间等进行调整。
4)根据上述信息d，网络侧可判断对应的门限是否配置的合理。例如，如果UE选择的SSB高于对应门限、但还是发生了失败，则可能门限配置得过低，此时可以调高该门限。
5)根据上述信息e、h、i、j和l中的至少一种，网络侧可判断是否要在2步随机接入和4步随机接入之间共用随机接入资源，以及共享多少随机接入资源。例如，当2步随机接入碰撞概率高，4步随机接入成功概率高，则网络侧可以考虑资源分配上向2步随机接入倾斜。
