本公开主张在2017年8月11日在中国提交的中国专利申请号No.201710687886.5的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及计算机技术领域，尤其涉及一种随机接入资源的处理方法和装置。
背景技术
未来第五代移动通信系统(5 th Generation，5G)中，为达到下行链路传输速率20Gbps，上行链路传输速率10Gbps的目标，高频通信和大规模天线技术将会被引入。高频通信可提供更宽的系统带宽，天线尺寸也可以更小，更加有利于大规模天线在基站(Node B，NB)和用户设备(User Equipment，UE)中部署。高频通信存在路径损耗较大、容易受干扰、链路较脆弱的缺点，而大规模天线技术可提供较大天线增益，因此，高频通信与大规模天线的结合是未来5G移动通信系统的必然趋势。然而，采用大规模天线技术不能解决全部高频通信的问题，如链路的脆弱性。当高频通信中遇到遮挡时，波束失败恢复机制可快速切换波束，将通信链路从较差的波束切换至较佳的波束，避免无线链路失败，有效提高链路的健壮性。
参见图1，波束失败恢复机制包括以下步骤：
步骤12，波束失败检测；
步骤14，新的候选波束识别；
步骤16，波束失败恢复请求发送；
步骤18，UE监测波束失败恢复请求gNB响应。
另外，5G系统支持基于非竞争物理随机接入信道(Physical Random Access Channel，PRACH)发送波束失败恢复请求，用于波束失败恢复请求发送的PRACH与普通PRACH资源正交，至少支持频分复用方式正交；5G 系统支持基于物理上行控制信信道(Physical Uplink Control Channel，PUCCH)发送波束失败恢复请求。
在LTE系统中，非竞争的随机接入资源(Contention-free RACH)和专有(dedicated)的基于竞争的随机接入的PRACH资源和preamble码均由演进型基站(evolutional Node B，eNB或e-Node B)提前配置，可以通过PDCCH order或者无线资源控制(Radio Resource Control，RRC)消息发送给UE。每次配置的专有PRACH资源只能用于一次RACH接入过程(包括msg.1的多次重传)。下次再做接入时，eNB会再为UE配置PRACH资源。
目前，在用于波束失败恢复的RACH资源激活/去激活过程中，由于下行波束失败，会出现网络侧设备无法将RACH资源的激活命令或去激活命令发送给UE的情况，导致网络和UE对RACH资源的配置理解不一样。进一步地，当激活命令未成功发送到UE，会造成RACH资源的浪费；当去激活命令未成功发送到UE，会造成UE进行波束失败恢复的随机接入过程冲突。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)，通用分组无线业务(General Packet Radio Service，GPRS)，长期演进(Long Term Evolution，LTE)/增强长期演进(Long Term Evolution Advanced，LTE-A)，New Radio(NR)等。
用户端(User Equipment，UE)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(Node B)，还可以是LTE中的eNB及5G基站(gNB)，本公开并不限定，但为描述方便，下述实施例以gNB为例进行说明。
参见图2，下面对本公开实施例的应用场景进行示例性地说明：
步骤22：网络侧设备为用户设备UE分配随机接入资源RACH，并告知UE；
步骤24：网络侧设备向UE发送指示信息，以告知UE分配的随机接入资源是否可用；
步骤26：UE反馈确认信息，以告知网络侧设备已收到指示信息；
步骤28：在UE发生波束失败时，基于随机接入资源向网络侧发起波束失败恢复的请求；
步骤210：网络侧设备响应UE发起的请求，并执行图1所示的波束失败恢复机制。
其中，不难理解的是随机接入资源也可以为预定义的随机接入资源。
以下结合附图，详细说明本公开各实施例提供的技术方案。
实施例1
图3为本公开实施例1提供的随机接入资源的处理方法的流程示意图，参见图3，该方法具体可以包括如下步骤：
步骤32、接收来自网络侧设备的第一指示信息，所述第一指示信息用于指示预设的随机接入资源是否可用；
其中，预设的随机接入资源可以举例为：网络侧设备为UE已分配的随机接入资源。已分配的随机接入资源包括：时域随机接入资源、频域随机接入资源、前导preamble码的分配、组成系统带宽的带宽部分BWP、波束资源、与波束资源相关联的同步信号块(Synchronization Signal Block，SS Block)/信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)中的至少一个。
不难理解的是，网络侧设备可以基于候选波束的ID为UE分配随机接入资源。例如：基于候选波束的ID，分配与ID相关联的时域随机接入资源和频域随机接入资源，然后，基于默认的规则，结合默认的组成系统带宽的带宽部分BWP和空域的随机接入资源组成随机接入资源。
步骤34、向所述网络侧设备发送第一确认信息，所述第一确认信息用于表示已收到所述第一指示信息。
需要说明的是，发送第一确认信息的方式举例如下：
UE通过上行物理控制信道PUCCH向所述网络侧设备反馈承载有所述第一确认信息的上行控制信息(Uplink Control Information，UCI)信息；或者，通过无线资源控制RRC向所述网络侧设备反馈承载有所述第一确认信息的RRC消息；或者，通过介质访问控制(Medium Access Control，MAC)层的控制元素(Control Element，CE)向所述网络侧设备反馈承载的所述第一确认信息。
相应地，网络侧设备也可通过与上述反馈方式对应的接收方式接收第一确认信息。
结合图2，需要说明的是，UE在接收到网络侧设备发送的第一指示信息后，基于反馈机制，向网络侧设备发送第一确认信息，以告知网络侧设备已收到第一指示信息，使得UE和网络侧设备对已分配的随机接入资源是否可用的“理解”保持一致。避免出现因为双方对已分配的随机接入资源是否可用的“理解”不同，导致资源浪费、以及无法正常进行波束失败恢复的问题。
例如：对于随机接入资源A，由于下行波束失败导致网络侧设备下发的指示信息没有被UE接收，因此，两者对随机接入资源A的“理解”不同。UE“理解”的是随机接入资源A不可用，网络侧“理解”的是随机接入资源A对UE可用。基于此情况，当UE发生波束失败时，由于UE认为随机接入资源A不可用，因此，无法基于随机接入资源A向网络侧设备发起波束失败恢复的请求。同时，由于网络侧设备认为随机接入资源A对UE是可用的，因此，不会再向UE指示随机接入资源A可用，也不会将随机接入资源A分配给其他UE使用，导致随机接入资源A被浪费。
进一步地，步骤32可以具体包括：
接收来自网络侧设备的激活指示信息，所述激活指示信息用于指示已分配的随机接入资源可用。或者，接收来自网络侧设备的去激活指示信息，所述去激活指示信息用于指示已分配或者已激活的随机接入资源不可用。
当接收到激活指示信息后，则在触发波束失败恢复时UE可基于所述已分配的随机接入资源发送波束失败恢复请求。
不难理解的是，分配的随机接入资源可能基于网络侧设备发送的第一指 示信息不断处于激活-去激活-激活-去激活的循环过程。
可见，本公开实施例通过对下行的指示信息增设反馈机制，以在UE接收到网络侧设备发送的第一指示信息时，向网络侧设备反馈第一确认信息，使得网络侧设备与用户侧设备均能够明确已分配的随机接入资源是否可用，进而能够合理利用随机接入资源，并保证波束失败恢复的正常进行。
实施例2
图4为本公开实施例2提供的随机接入资源的处理方法的流程示意图，参见图4，该方法具体可以包括如下步骤：
步骤42、接收来自所述网络侧设备的分配信息，所述分配信息用于表示所述网络侧设备基于所述分配请求分配的随机接入资源；
步骤44、接收来自网络侧设备的第一指示信息，所述第一指示信息用于指示已分配的随机接入资源是否可用；
步骤46、向所述网络侧设备发送第一确认信息，所述第一确认信息用于表示已收到所述第一指示信息。
需要说明的是，本实施例中的步骤44和步骤46分别与实施例1中的步骤32和步骤34相对应，故，此处不再赘述，相似之处请参见实施例1中的相关描述。
本实施例中，UE获取随机接入资源的方式可以分为如下两种方案：
方案一、UE主动向网络侧设备发送分配请求，以请求网络侧设备分配随机接入资源。网络侧设备基于分配请求为UE分配随机接入资源，并通过分配信息的形式告知UE已分配的随机接入资源。
方案二、网络侧设备主动为UE分配随机接入资源，并以分配信息的形式告知UE。
不难理解的是，在上述两种方案中，UE在接收到分配信息后，可选择性地向网络侧设备返回确认信息，以告知网络侧设备已收到分配信息。
另外，网络侧设备在为UE分配随机接入资源后，还会告知UE分配的随机接入资源的是否可用，例如：将是否可用的指示信息携带在分配信息中，或者，由UE自行检测已分配的随机接入资源是否可用，例如：尝试性地发起波束失败恢复请求。基于分配的随机接入资源的状态，本公开实施例可以 包括以下两种方案：
方案一、若UE得知分配的随机接入资源为可用状态，则在触发波束失败时，UE基于随机接入资源向网络侧发起波束失败恢复的请求。
方案二、若UE得知分配的随机接入资源为不可用状态，则在收到网络侧设备发送的激活指示信息后才可使用；然后，反馈确认信息；在触发波束失败时，UE基于随机接入资源向网络侧设备发起波束失败恢复的请求。
其中，触发波束失败的条件举例如下：
1、当波束失败的次数达到第一预定阈值时，触发波束失败；
2、当一定时间内，波束失败的次数到达第二预定阈值时，触发波束失败；
3、当波束失败的时长达到第三预定阈值时，触发波束失败。
可见，本公开实施例在实施例1的基础上，通过网络侧和UE侧之间关于分配随机接入资源的方案，灵活地分配随机接入资源。而且，本公开实施例通过设置判定触发波束失败的条件，以准确判定UE是否发生波束失败，避免出现未发生波束失败而执行了波束失败恢复机制的情况，达到进一步地避免资源被浪费的效果。
实施例3
图5为本公开实施例3提供的随机接入资源的处理方法的流程示意图，参见图5，该方法具体可以包括如下步骤：
步骤52、UE接收来自所述网络侧设备的分配信息，所述分配信息用于表示分配的随机接入资源；
步骤54、接收来自所述网络侧设备的第二指示信息，所述第二指示信息用于指示所述已分配的随机接入资源被释放；
其中，接收第二指示信息的方式可以为通过介质访问控制MAC层的控制元素CE接收承载的所述第二指示信息。
步骤56、向所述网络侧设备发送第二确认信息，所述第二确认信息用于表示已收到所述第二指示信息。
其中，发送第二确认信息的方式可以为通过上行物理控制信道PUCCH向所述网络侧设备反馈承载有所述第二确认信息的上行控制信息UCI信息；或者，通过无线资源控制RRC向所述网络侧设备反馈承载有所述第二确认信 息的RRC消息；或者，通过介质访问控制MAC层的控制元素CE向所述网络侧设备反馈承载的所述第二确认信息。
需要说明的是，步骤52和实施例2中UE获取到分配的随机接入资源的方案相似，故，此处不再赘述。相似之处，请参见实施例2中的相关陈述。
可见，本公开实施例在网络侧为UE侧分配随机接入资源之后，还会将分配的随机接入资源释放，释放之后的随机接入资源对UE不可用。网络侧设备可将释放后的随机接入资源分配给其他UE侧，以达到合理安排随机接入资源、提高随机接入资源使用效率的目的。
实施例4
图6为本公开实施例4提供的随机接入资源的处理方法的流程示意图，参见图6，该方法可以具体包括如下步骤：
步骤62、网络侧设备向用户设备发送第一指示信息，所述第一指示信息用于指示预设的随机接入资源是否可用；
其中，预设的随机接入资源可以为网络侧设备为UE分配的随机接入资源也可以为预定义的随机接入资源。下面以网络侧设备为UE分配的随机接入资源为例进行说明：
步骤62的一种实现方式可以为：
向所述用户设备发送激活指示信息，所述激活指示信息用于指示已分配的随机接入资源可用，或者，向所述用户设备发送去激活指示信息，所述去激活指示信息用于指示已分配或者已激活的随机接入资源不可用。
其中，发送去激活指示信息的条件可以为：在确定所述已分配的随机接入资源处于可用状态时，或者，在完成响应波束失败恢复请求后且所述已分配的随机接入资源处于可用状态，发送去激活指示信息。
发送激活指示信息的条件可以为：在确定所述已分配的随机接入资源处于不可用状态，发送激活指示信息。
另外，向所述用户设备发送第一指示信息的方式可以包括如下几种：
通过下行物理控制信道PDCCH向所述用户设备发送承载有第一指示信息的下行控制信DCI信息；或者，通过无线资源控制RRC向所述用户设备发送承载有第一指示信息的RRC消息；或者，通过媒体存取控制MAC的控 制元素CE向所述用户设备发送承载的第一指示信息。
其中，已分配的随机接入资源包括：时域随机接入资源、频域随机接入资源、前导preamble码的分配、组成系统带宽的带宽部分BWP、波束资源、与波束资源相关联的同步信号块SS Block/信道状态信息参考信号CSI-RS中的至少一个。
不难理解的是，网络侧设备可以基于候选波束的ID为UE分配随机接入资源。例如：基于候选波束的ID，分配与ID对应的时域随机接入资源和频域随机接入资源，然后，基于默认的规则，结合默认的组成系统带宽的带宽部分BWP和空域的随机接入资源组成随机接入资源。
步骤64、接收来自所述用户设备的第一确认信息，所述第一确认信息用于表示所述第一指示信息的接收方已收到所述第一指示信息。
需要说明的是，本公开实施例与实施例1相对应，故，此处不再赘述，相似之处，请参见实施例1中的相关描述。
可见，本公开实施例通过对下行的指示信息增设反馈机制，以在UE侧接收到指示信息时，向网络侧返回收到指示信息的确认信息。避免出现由于两者对已分配的随机接入资源是否可用的“理解”不同，导致资源浪费，或者，“理解”冲突从而无法正常进行波束失败恢复的问题。
实施例5
图7为本公开实施例5提供的随机接入资源的处理方法的流程示意图，参见图7，该方法可以具体包括如下步骤：
步骤72、网络侧设备为UE分配可用的随机接入资源；
其中，步骤72具体可以包括两种实现方式：
第一种、网络侧设备在接收到UE发送的分配请求后，为UE分配随机接入资源，其中，分配请求用于请求分配随机接入资源；
第二种、网络侧设备主动为UE分配随机接入资源。例如：
在网络侧设备响应UE发起的第一次波束失败恢复请求时，向UE发送分配信息，所述已分配的随机接入资源用于所述用户设备发起第二次波束失败恢复请求。
步骤74、如果UE触发波束失败条件，则UE使用分配的随机接入资源 向网络侧设备发送波束失败恢复请求。
步骤76、网络侧设备响应波束失败恢复请求；
需要说明的是，结合图1，步骤76可以通过执行波束失败恢复机制来响应波束失败恢复请求；
其中，所述波束失败恢复机制用于将通信链路从失败的波束切换至可用的波束。
步骤78、向UE发送第二指示信息，所述第二指示信息用于指示所述已分配的随机接入资源被释放。
需要说明的是，允许发送第二指示信息的条件为网络侧决定，可以举例如下：
确定波束处于空闲状态，或者，完成响应波束失败恢复请求后，或者，确定所述已分配的随机接入资源处于不可用状态时。
向所述用户设备发送第二指示信息的方式可以为：
通过介质访问控制MAC层的控制元素CE向所述用户设备发送承载的所述第二指示信息；
相应地，UE可通过介质访问控制MAC层的控制元素CE接收对应的所述第二指示信息。
步骤710、UE向网络侧设备发送第二确认信息，所述第二确认信息用于表示所述第二确认信息的发送方已收到所述第二指示信息。
需要说明的是，UE可通过介质访问控制MAC层的控制元素CE向网络侧设备发送承载的所述第二确认信息，相应地，网络侧设备通过介质访问控制MAC层的控制元素CE接收对应的所述第二确认信息。
可见，本公开实施例中网络侧设备为UE分配可用的随机接入资源，以在UE发生波束失败时，可直接基于可用的随机接入资源向网络侧设备发起波束失败恢复，以尽快完成波束失败恢复。而且，本公开实施例中网络侧设备还可基于实际情况自行决定是否释放已分配的随机接入资源，并将已分配的随机接入资源分配给其他UE，进而达到进一步地提高资源使用率的目的。
实施例6
图8为本公开实施例6提供的随机接入资源的处理方法的流程示意图， 参见图8，该方法可以具体包括如下步骤：
步骤82、网络侧设备为UE分配随机接入资源。
其中，网络侧设备分配的随机接入资源为未激活的随机接入资源；
步骤82的实现方式与实施例7中步骤72的实现方式相似，故，此处不再赘述。
步骤84、网络侧设备向UE发送第一指示信息，第一指示信息用于指示已分配的随机接入资源是否可用；
其中，第一指示信息包括：激活指示信息或者去激活指示信息，激活指示信息用于激活已分配的随机接入资源，以使已分配的随机接入资源可用；去激活指示信息用于去激活已分配或者已激活的随机接入资源，以使已分配的随机接入资源不可用。
不难理解的是，激活-去激活可以是一个不断变化的过程，网络侧设备可自由决定激活已分配的随机接入资源给UE用，也可去激活可用的已分配的随机接入资源，并将其分配给其他UE使用。
步骤86、UE向网络侧设备反馈第一确认信息，以告知网络侧设备UE已收到第一指示信息；
步骤88、若第一指示信息为激活指示信息，则在触发波束失败条件时，UE可基于已分配的随机接入资源向网络侧设备发起波束失败恢复的请求；
步骤810、网络侧设备执行波束失败恢复机制，以响应UE发送的响应波束失败恢复的请求；
步骤812、网络侧设备可选择性地决定释放已分配的随机接入资源，或者，再次循环去激活-激活的过程；
步骤814、当再次触发波束失败条件时，UE再次发起波束失败恢复的请求；
步骤816、网络侧设备再次响应波束失败恢复的请求；
步骤818、当满足预定条件时，网络侧设备向UE发送第二指示信息，第二指示信息用于指示释放已分配的随机接入资源；
步骤820、UE发送第二确认信息，以告知网络侧设备已收到第二指示信息。
其中，网络侧设备可自行决定在步骤84-步骤816中的任一可行时间点执行步骤818。例如：完成步骤84后，即可直接告知UE已分配随机接入资源被释放；或者，在完成步骤810或步骤816对应的波束失败恢复后，释放已分配随机接入资源。
可见，本公开实施例与实施例5的不同之处在于，网络侧设备为UE分配未激活的随机接入资源，需要在得到网络侧设备的进一步地激活之后，方可用于发起波束失败恢复请求，进一步地增加了网络侧设备的分配随机接入资源的灵活性。
实施例7
图9为本公开实施例7提供的随机接入资源的处理方法的流程示意图，参见图9，该方法在实施例1的基础上，进一步地包括如下步骤：
步骤92、在第一时刻向UE发送第一指示信息，所述第一指示信息用于指示预设的随机接入资源是否可用；
步骤94、若在预定时间内未接收到确认信息，则在第二时刻再次向UE发送所述第一指示信息；
其中，所述确认信息用于表示UE已收到所述指示信息。
其中，步骤94的一种实现方式可以为：
使用第一波束向所述用户设备发送所述第一指示信息；
其中，所述第一波束为当前使用的发送所述第一指示信息的波束之外的波束。
本公开实施例与实施例1相对应，故，相似之处此处不再赘述。
另外，本公开实施例在实施例1的基础上，增设补救措施，以在未收到第一确认信息时，网络侧设备再次发送第一指示信息。避免由于意外或者极端情况导致第一指示信息无法正常传送至UE，或者，第一确认信息无法正常传送至网络侧设备的缺陷，达到进一步地避免已分配的随机接入资源被浪费、波束失败恢复无法正常进行的目的。
对于上述方法实施方式，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本公开实施方式并不受所描述的动作顺序的限制，因为依据本公开实施方式，某些步骤可以采用其他顺序或者同 时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施方式均属于可选实施方式，所涉及的动作并不一定是本公开实施方式所必须的。

在接收到激活指示信息后，若触发波束失败恢复，第五发送单元(图中未示出)基于所述已分配的随机接入资源发送波束失败恢复请求。
若接收到的是去激活指示信息，则已分配的随机接入资源不可用，需要在接收到激活指示信息后，方可使用。
第一发送单元102，具体用于通过上行物理控制信道PUCCH向网络侧设备反馈承载有所述第一确认信息的上行控制信息UCI信息；或者，通过无线资源控制RRC向网络侧设备反馈承载有所述第一确认信息的RRC消息；或者，通过介质访问控制MAC层控制元素CE向网络侧设备的反馈承载的所述第一确认信息。
相应地，网络侧设备可对应采用相同方式接收第一发送单元102反馈的 第一确认信息。
本公开实施例8的第二种实施方式为：

相应地，网络侧设备执行波束失败恢复机制，以响应波束失败恢复请求。
本公开实施例8的第三种实施方式为：

可见，本公开实施例通过对下行的指示信息增设反馈机制，以在UE接收到网络侧设备发送的指示信息时，向网络侧设备反馈收到指示信息的确认信息，使得网络侧设备与用户侧设备均能够明确已分配的随机接入资源是否可用，进而能够合理利用随机接入资源，并保证波束失败恢复的正常进行。
