具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
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，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的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。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。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。
本文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，并且也可用于各种无线通信系统，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。术语“系统”和“网络”常被可互换地使用。CDMA 系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文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。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
与以往的移动通信系统相比，未来移动通信系统需要适应更加多样化的场景和业务需求。新空口(New Radio，NR)的主要场景包括移动宽带增强(Enhanced Mobile Broadband，eMBB)、大规模物联网(massive Machine Type of Communication，mMTC)、超高可靠超低时延通信(Ultra Reliable&Low Latency Communication，URLLC)，这些场景对系统提出了高可靠、低时延、大带宽、广覆盖等要求。
在传统的上行传输模式下，用户设备(User Equipment，UE)如果需要发送上行数据，首先要通过随机接入过程获取上行同步信息，即从网络侧获得 上行定时提前(Timing advance，TA)信息。在取得上行同步信息后，UE可以通过动态调度或半静态调度发送上行数据。
当上行数据包较小时，UE通过随机接入过程获得上行同步信息后发送上行数据的方式会造成资源和电量的消耗，因此在mMTC场景下，UE可在非同步的状态下，发送上行数据。
与随机接入过程类似，UE发送随机接入前导码(preamble)时也是处于非同步状态，因此如图1所示，需要通过在preamble中添加循环前缀(Cyclic Prefix,CP)来抵消传输延迟带来的影响。
在4步随机接入过程(Random Access Channel，RACH)中，如图2所示，UE首先向网络侧设备(比如基站)发送msg1，包含preamble；网络侧设备检测到preamble后，将发送msg2，包含该preamble对应的随机接入响应(RAR)消息；UE接收到msg2后，根据RAR的指示，发送msg3；网络侧设备收到msg3后，将发送msg4，包含竞争解决标识(contention resolution ID)；UE收到msg4，即完成4步随机接入。
在2步RACH中，UE向网络侧设备发送msgA，网络侧设备收到msgA后，向UE发送msgB，UE收到msgB后，即完成2步随机接入。
如图3所述，一个时隙(slot)可以包含下行(downlink)，上行(uplink)和灵活(flexible)的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，其中，Flexible符号可以被改写为下行或者上行符号。
时隙格式指示(slot format indicator，SFI)可以指示一个或者多个slot的格式。SFI在组公共(Group common，GC)-PDCCH中发送。SFI可以灵活地根据需求改变slot的格式，以满足业务传输需求，UE根据SFI的指示决定是否监测物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
基站可以通过高层参数UL-DL-configuration-common和UL-DL-configuration-common-Set2(可选的)半静态地给UE配置一个或者多个小区专属(cell-specific)的slot格式。基站也可以通过高层参数UL-DL-configuration-dedicated半静态地UE配置一个或者多个UE专属(UE-specific)的slot格式。
基站可以通过GC-PDCCH中承载的SFI改写半静态配置中的flexible  symbol或者slot。
由UE专属RRC配置隐式指示的传输方向被统称为测量(measurement)，包括：
UE专属的RRC信令配置的周期性或者半持续的CSI-RS测量，周期性的CSI上报，周期性或者半持续的探测参考信号(Sounding Reference Signal，SRS)所隐式指示的上下行传输方向
UE专属的RRC配置的PRACH资源，type1和type2免授权上行传输。
对type2的免授权上行传输，只有第一个激活的资源上的传输被看做UE专属的数据(UE-specific data)。
UE-specific传输包括物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，PDSCH的A/N反馈，下行控制信息(Downlink Control Information，DCI)触发的非周期测量等。
在时分双工(Time Division Duplexing，TDD)情况下，对于某一个传输时刻，传输的方向是根据网络侧配置的TDD配置信息确定的。网络侧在给UE配置发送msgA的传输时刻时，可能会存在msgA传输时刻与网络侧配置的TDD配置信息冲突的情况，如果UE在冲突的时域位置上发送msgA，将会导致对网络侧的下行信号传输造成干扰。
为了解决上述技术问题，本公开的实施例提供一种随机接入方法及装置、用户设备，能够解决用户设备在进行随机接入过程时，随机接入消息的传输时刻与网络侧消息指示的时域资源冲突的问题。
本公开的实施例提供一种随机接入方法，应用于用户设备，如图4所示，包括：
步骤101：在随机接入消息的时域资源与网络侧消息指示的时域资源冲突时，执行以下任一种：
在所述随机接入消息的时域资源进行所述随机接入消息的传输；
取消所述随机接入消息的传输；
推迟所述随机接入消息的传输；
忽略所述网络侧消息。
本实施例中，在随机接入消息的时域资源与网络侧消息指示的时域资源冲突时，可以在随机接入消息的时域资源进行随机接入消息的传输，或者取消随机接入消息的传输，或者推迟随机接入消息的传输，或者忽略网络侧消息。本公开给出了在TDD场景下，随机接入消息的传输时刻与网络侧消息指示的传输方向发生冲突时的具体解决方案，能够解决用户设备在进行随机接入过程时，随机接入消息的传输时刻与网络侧消息指示的时域资源冲突的问题。
随机接入消息的时域资源与网络侧消息指示的时域资源冲突可以包括：所述随机接入消息的时域资源与所述网络侧消息指示的以下资源中的至少一个至少部分重叠：
下行传输资源；下行时域资源；灵活时域资源；
其中，随机接入信息的时域资源可以是网络侧预配置的。
一具体实施例中，所述网络侧消息为下行控制信息DCI，网络侧消息指示的时域资源可以由DCI指示的时隙格式信息确定，该时隙格式信息中指示了哪些符号是上行时域资源，哪些符号是下行时域资源，哪些符号是灵活时域资源；网络侧消息指示的时域资源还可以是由DCI直接指示的下行接收时域资源，在DCI指示下行接收时域资源时，该DCI可以是下行调度授权(DL grant)。
可选地，所述忽略所述网络侧消息包括以下任一种：
丢弃所述DCI；
不接收下行传输信号，其中，下行传输信号包括以下至少一种：物理下行控制信道(Physical Downlink Control Channel，PDCCH)，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
具体地，在DCI指示随机接入消息的时域资源为下行传输资源和/或下行时域资源和/或灵活时域资源时，用户设备在接收到DCI后可以忽略该DCI，丢弃该DCI。
一具体实施例中，所述取消所述随机接入消息的传输包括：
在接收所述DCI的时域资源与发送所述随机接入消息的时域资源之间的 时间间隔大于等于预设阈值时，取消所述随机接入消息的传输，这样可以避免随机接入消息的传输与网络侧指示的传输方向冲突，其中，预设阈值可以根据实际需要进行设定。
进一步地，上述随机接入方法还包括：
在接收所述DCI的时域资源与发送所述随机接入消息的时域资源之间的时间间隔不大于预设阈值时，在所述随机接入消息的时域资源上进行所述随机接入消息的传输。
其中，所述时间间隔为接收所述DCI的时域资源的结束位置到发送所述随机接入消息的时域资源的任意位置之间的时长。
具体地，所述时间间隔可以为接收所述DCI的时域资源的结束位置到所述随机接入消息的时域资源的结束位置之前的任意一个位置之间的时长。
上述取消所述随机接入消息的传输可以是取消全部随机接入消息的传输，也可以是取消部分随机接入消息的传输。在接收DCI的时域资源的结束时刻与发送随机接入消息的时域资源的起始时刻的时间间隔，大于或等于预设阈值时，取消所述随机接入消息的全部传输；在接收DCI的时域资源的结束时刻与发送随机接入消息的时域资源的结束位置之前的任一位置的时间间隔，大于或等于预设阈值时，取消所述随机接入消息的部分传输，所述取消的随机接入消息的部分传输的起始时刻与接收DCI的时域资源的结束时刻的时间间隔，大于或等于预设阈值。
一具体实施例中，所述推迟所述随机接入消息的传输包括：
在最近的可用上行时域资源上进行所述随机接入消息的传输。其中，可用上行时域资源可以是DCI指示的上行时域资源，这样可以避免随机接入消息的传输与网络侧指示的传输方向冲突。
另一具体实施例中，所述在所述随机接入消息的时域资源进行所述随机接入消息的传输包括：
在所述随机接入消息的时域资源为网络侧消息指示的灵活时域资源时，在所述随机接入消息的时域资源进行所述随机接入消息的传输。
上述实施例中，随机接入消息可以为4步随机接入过程中的随机接入消息，也可以为2步随机接入过程中的随机接入消息，具体地，随机接入消息 可以为2步随机接入过程中的msgA，所述随机接入消息包括随机接入信道PRACH和上行数据信道PUSCH中的至少一个。
另一具体实施例中，用户设备不期望随机接入消息的时域资源与网络侧消息指示的时域资源发生冲突，即用户设备在接收到网络侧消息，发现网络侧消息指示的时域资源与随机接入消息的时域资源冲突时，可以认为网络侧消息是错误的。一具体示例中，在DCI指示随机接入消息的时域资源为下行时域资源或灵活时域资源时，用户设备认为这是种错误情况。
上述实施例中，随机接入消息的时域资源可以是上行时域资源也可以是灵活时域资源。一具体示例中，如果随机接入消息的时域资源位于灵活时域资源上，在DCI指示随机接入消息的时域资源为下行时域资源或灵活时域资源时，用户设备认为这是种错误情况。另一具体示例中，如果随机接入消息的时域资源位于灵活时域资源上，在原本应接收DCI的时刻UE未检测到指示时隙格式信息的DCI，如果该时刻与发送所述随机接入消息的时域资源之间的时间间隔大于等于预设阈值时，取消所述随机接入消息的传输；否则，在所述随机接入消息的时域资源上进行所述随机接入消息的传输。
下面结合具体的实施例对本公开的技术方案进行进一步介绍：
实施例1：
本实施例中，网络侧配置UE在一个时隙内的一组符号资源上发送msgA PRACH和/或PUSCH，并且UE检测到一个DCI指示UE在该时隙内的符号资源上接收CSI-RS或PDSCH，DCI所指示的符号资源与UE发送msgA PRACH和/或PUSCH的符号资源在时间上重叠。
一具体示例中，如果从检测到DCI所在的时域资源的结束位置，到传输msgA PRACH和/或PUSCH所在时隙的任一符号资源比如符号资源A之间的时间间隔，小于预设阈值，则UE不取消符号资源A之前的msgA PRACH和/或PUSCH的传输；UE取消从符号资源A开始的剩余的msgA PRACH和/或PUSCH的传输。
另一具体示例中，在一个有效的msgA PRACH和/或PUSCH传输机会之前的预设时间内比如之前的Ngap个符号资源内，UE不接收在一个时隙内与该msgA PRACH和/或PUSCH传输机会对应的符号资源冲突的PDCCH， PDSCH或CSI-RS。
实施例2：
本实施例中，网络侧配置或指示UE在一个时隙内的一组符号资源上发送msgA PRACH和/或PUSCH，并且UE检测到一个指示时隙格式信息的DCI，UE不期望该时隙格式信息指示的符号资源的传输方向与UE发送msgA PRACH和/或PUSCH的符号资源冲突，比如UE不期望该时隙格式信息指示UE发送msgA PRACH和/或PUSCH的符号资源为下行符号资源。
实施例3:
本实施例中，网络侧配置或指示UE在一个时隙内的一组符号资源上发送msgA PRACH和/或PUSCH。
如果发送msgA PRACH和/或PUSCH的符号资源为半静态(semi-static)TDD配置信息指示的flexible资源，或者UE未配置有semi-static TDD配置信息时，在UE检测到一个指示时隙格式信息的DCI时，
如果该时隙格式信息指示的UE发送msgA PRACH和/或PUSCH的符号资源为flexible符号资源，则UE在网络侧所配置或指示的时域资源上发送msgA PRACH和/或PUSCH；
如果该时隙格式信息指示的UE发送msgA PRACH和/或PUSCH的符号资源为上行符号资源，则UE在网络所配置或指示的时域资源上发送msgA PRACH和/或PUSCH；
或者UE不期望该时隙格式信息指示UE发送msgA PRACH和/或PUSCH的符号资源为下行符号资源，这样在该时隙格式信息指示UE发送msgA PRACH和/或PUSCH的符号资源为下行符号资源时，UE认为是错误情况；
或者UE不期望该时隙格式信息指示UE发送msgA PRACH和/或PUSCH以及PUSCH repetitions的符号资源为下行符号资源或flexible符号资源，这样在该时隙格式信息指示UE发送msgA PRACH和/或PUSCH以及PUSCH repetitions的符号资源为下行符号资源或flexible符号资源，UE认为是错误情况。
实施例4：
本实施例中，网络侧配置或指示UE在一个时隙内的一组符号资源上发 送msgA PRACH和/或PUSCH。
UE检测到一个指示时隙格式信息的DCI，该时隙格式信息指示UE发送msgA PRACH和/或PUSCH的符号资源为下行符号资源或flexible符号资源；或者UE检测到一个DCI指示UE在发送msgA PRACH和/或PUSCH的(部分或全部)符号资源上接收CSI-RS或PDSCH；
如果从检测到该DCI所在的时域资源的结束位置，到传输msgA PRACH和/或PUSCH所在时隙的任一符号资源之间的时间间隔，小于预设阈值，则UE不取消该符号资源之前的msgA PRACH和/或PUSCH的传输；UE取消从该符号资源开始的剩余的msgA PRACH和/或PUSCH的传输。
实施例5：
本实施例中，网络侧配置或指示UE在一个时隙内的一组符号资源上发送msgA PRACH和/或PUSCH。
其中，发送msgA PRACH和/或PUSCH的符号资源为semi-static TDD配置信息指示的flexible符号资源，或者UE未配置有semi-static TDD配置信息，UE未检测到一个指示发送msgA PRACH和/或PUSCH所在时隙的时隙格式信息的DCI，
如果从检测DCI所在的时域资源的结束位置(即原本应检测到DCI的时域资源的结束位置)，到传输msgA PRACH和/或PUSCH所在时隙的任一符号资源之间的时间间隔，大于或等于预设阈值，则UE取消从该符号资源开始的msgA PRACH和/或PUSCH的传输；
如果从检测DCI所在的时域资源的结束位置(即原本应检测到DCI的时域资源的结束位置)，到传输msgA PRACH和/或PUSCH所在时隙的任一符号资源之间的时间间隔，小于预设阈值，则UE不期望取消该符号资源之前的msgA PRACH和/或PUSCH的传输。
实施例6：
本实施例中，网络侧指示UE在一个时隙内的一组符号资源上发送msgA PRACH和/或PUSCH，并且UE检测到一个指示时隙格式信息的DCI，
如果该时隙格式信息指示UE发送msgA PRACH和/或PUSCH的符号资源为下行符号资源或flexible符号资源，UE推迟到下一组可用的上行符号资 源上，进行msgA PRACH和/或PUSCH的传输。
在TDD场景下，网络侧在给UE配置发送msgA的传输时刻时，可能会存在msgA传输时刻与网络侧配置的TDD配置信息冲突的情况，通过上述实施例的方案，UE可以确定冲突的时域位置上的有效msgA传输时刻，避免对网络的下行信号传输造成干扰。除此之外，也能够保证UE发送的msgA的传输时刻与该UE接收下行信号之间有足够的切换时间间隔，避免干扰下行接收。
