Description

随机接入方法、终端及网络设备
本申请要求于2017年11月17日提交中国国家知识产权局、申请号为201711149117.6、申请名称为“随机接入方法、终端及网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及一种随机接入方法、终端及网络设备。
背景技术
新空口(New Radio，NR)技术中，基站通过多个波束发送下行信号，其中下行信号可以是：下行同步信号块(synchronization/PBCH signal block，SS/PBCH block)、下行同步信号块、系统信息块、剩余最小系统信息、第一系统信息块NR SIB1、第0系统信息块NR SIB0、半静态配置的下行子帧和/或时隙和/或OFDM符号、预留的下行信号、下行解调参考信号(Demodulation Reference Signal，DMRS)、下行信道状态信息参考信号(Channel state information–reference signal，CSI-RS)。具体地，基站利用多个波束实现对小区的覆盖，基站与终端通信过程中，需要合理的波束方向才能进行通信，需要基站需要合理的波束方向接收终端发送的随机接入前导、以及向终端发送随机接入响应等。其中，下行信号的发送采用时分的方式，即分别在不同时间发送不同的下行信号，也在不同时间接收终端发送的随机接入前导。而且，NR技术中，一个下行信号集的下行信号的最大数目根据频段的不同可以不同。例如：在3千兆赫兹(GHz)以下一个下行信号集的下行信号的最大数目为4个；在3～6GHz时一个下行信号集的下行信号的最大数目为8个；在6GHz以上一个下行信号集的下行信号的最大数目为64个。下行信号集中所有下行信号映射在5毫秒(ms)的窗口内的不同时隙和正交频分复用(orthogonal frequency division multiplexing，OFDM)符号上。
具体地，下行信号集以周期发送，且一个下行信号集中实际发送的下行信号可能不是最大数目，例如：在6GHz以下时，由8比特指示8个下行信号是否实际发送；在6GHz以上时，采用8+8的方式指示下行信号是否实际发送：64个下行信号分成8个组，每个组8个下行信号，由8比特指示每个组中的下行信号是否发送，另外还有8比特指示8个下行信号集是否发送。
但是，NR技术中发送下行信号集的周期较小，最小可以为5ms，也就是一个系统帧中几乎所有时隙都可能有下行信号发送。相应地，终端发送的随机接入前导会配置在上行时间上，那么基站发送下行信号的时间就可能与终端发送上行随机接入前导的时间冲突。

S202、终端根据实际可用的随机接入资源、以及下行信号与随机接入资源的关联关系，确定实际发送的下行信号对应的目标随机接入资源。
即在实际可用的随机接入资源中确定实际发送的下行信号对应的目标随机接入资源，即不会使用与实际发送的下行信号位置重合(本申请中还可以理解为：部分重叠/冲突/占用(overlap/conflict/occupy/overlay/intersect/cross)等)的随机接入资源来发送上行信息。
S203、终端采用目标随机接入资源，向网络设备发送随机接入前导。
本实施例中，终端根据随机接入资源的位置信息、以及网络设备实际发送的下行信号的时间位置信息，确定实际可用的随机接入资源，并根据实际可用的随机接入资源、以及下行信号与随机接入资源的关联关系，确定实际发送的下行信号对应的目标随机接入资源，进而采用目标随机接入资源，向网络设备发送随机接入前导。避免了实际发送的下行信号和上行发送的随机接入前导冲突。
相应地，网络侧设备也会确定实际可用的随机接入资源以及目标随机接入资源，以便针对性地接收随机接入前导。
图3为本申请另一实施例提供的随机接入方法流程示意图，如图3所示，该方法包括：
S301、网络设备根据随机接入资源的时间位置信息、实际发送的下行信号的时间位置信息，确定实际可用的随机接入资源，其中，实际可用的随机接入资源与实际发送的下行信号位置不重合。
类似地，网络设备可以根据帧结构配置索引和/或时隙结构信息，确定系统帧中的上行子帧、时隙、OFDM符号的数量以及时间信息。进而可以根据随机接入配置索引、随机接入前导子载波间隔，确定随机接入资源所在的上行子帧、时隙、OFDM符号的数量和时间信息。
进一步地，网络设备再结合实际发送的下行信号指示信息、下行信号集周期信息，确定实际可用的随机接入资源。
S302、网络设备根据实际可用的随机接入资源、以及下行信号与随机接入资源的关联关系，确定实际发送的下行信号对应的目标随机接入资源。
S303、网络设备根据实际发送的下行信号对应的目标随机接入资源，接收终端发送的随机接入前导。
需要说明的是，网络设备和终端遵循同样的规则确定实际可用的随机接入资源、下行信号与随机接入资源的关联关系、目标随机接入资源等相关参数。即网络设备会知道终端在哪些随机接入资源发送随机接入前导，进而在这些随机接入资源上接收随机接入前导，以完成随机接入过程。也会确定出在哪些随机接入资源，终端不发送随机接入前导了。
本实施例中，网络设备可以根据随机接入资源的时间位置信息、实际发送的下行信号的时间位置信息，确定实际可用的随机接入资源，其中，实际可用的随机接入资源与实际发送的下行信号位置不重合，并根据实际可用的随机接入资源、以及下行信号与随机接入资源的关联关系，确定实际发送的下行信号对应的目标随机接入资源，进而根据实际发送的下行信号对应的目标随机接入资源，接收终端发送的随机接入前导。避免了实际发送的下行信号和上行发送的随机接入前导冲突。
上述下行信号时间位置可以由下述一项或多项确定：下行信号所在的时隙、或者所述 下行信号所在的OFDM符号、所述时隙基于所述下行信号的子载波间隔、下行/上行保护时间，所述下行/上行保护时间为一段时间间隔。
在上述实施例的基础上，终端根据随机接入资源的时间位置信息、以及网络设备实际发送的下行信号的时间位置信息，确定实际可用的随机接入资源，可以为：根据随机接入资源的时间位置信息、以及网络设备实际发送的下行信号的时间位置信息，确定与实际发送的下行信号时间位置重合的随机接入资源。进而将与实际发送的下行信号时间位置不重合的随机接入资源作为实际可用的随机接入资源。
具体地，终端确定与实际发送的下行信号时间位置重合的随机接入资源不可用，即不使用与实际发送的下行信号时间位置重合的随机接入资源发送随机接入前导。相应地，确定与实际发送的下行信号时间位置不重合的随机接入资源作为实际可用的随机接入资源。
其中，终端确定与实际发送的下行信号时间位置重合的随机接入资源不可用，可以是将与实际发送的下行信号时间位置重合的随机接入资源打孔(本申请中还可以理解为：删除/释放(puncture/release/delete/remove)等)。
基于同样的原理，终端确定与实际发送的下行信号时间位置重合的随机接入资源不可用，即与实际发送的下行信号时间位置重合的部分无需接收随机接入前导。
本申请中，所述随机接入资源所在时隙基于以下至少一个信号的子载波间隔：随机接入消息1(MSG1)、随机接入消息3(MSG3)、上行初始接入带宽、下行初始接入带宽、下行同步信号块、系统信息(例如第一新空口系统信息块NR SIB1、第0新空口系统信息块NR SIB0)、剩余最小系统信息(remaining minimum system information，RMSI)、其它下行信号(例如半静态配置的下行子帧和/或时隙和/或OFDM符号)的子载波间隔，或者所述随机接入资源所在时隙长度由网络设备指示。
第一新空口系统信息块NR SIB1、第0新空口系统信息块NR SIB0、所述下行信号为半静态配置的下行子帧和/或时隙和/或OFDM符号、所述下行信号中一项或多项为预留的下行信号。
本申请中，下行信号时间位置是指所述下行信号所在的时隙和/或OFDM符号、所述时隙和/或OFDM符号基于所述下行信号的子载波间隔。
所述下行信号时间位置还可以包括下行/上行保护时间(guard period，例如用于下行与上行切换)，所述下行/上行保护时间为一段时间间隔。
在本申请中，由于下行同步信号块、下行同步信号块、系统信息块、剩余最小系统信息、第一新空口系统信息块NR SIB1、第0新空口系统信息块NR SIB0、半静态配置的下行子帧和/或时隙和/或OFDM符号、预留的下行信号、半持续调度的下行子帧和/或时隙和/或OFDM符号、下行解调参考信号、下行信道状态信息参考信号)的子载波间隔、上行PRACH、半静态配置的上行子帧和/或时隙和/或OFDM符号、预留的上行信号、半持续调度的上行子帧和/或时隙和/或OFDM符号的子载波间隔各不一样，对应的时间尺度，例如时隙、OFDM符号长度也不一样，因此进行随机接入资源调整时需要考虑各个不同信号子载波之间的差异。
具体地，以下行同步信号块与随机接入资源进行重叠时的调整方式为例进行说明，值得注意的是，这里的实施例考虑的下行同步信号块是基于下行同步信号块子载波对应的时间尺度，随机接入资源是基于随机接入前导子载波对应的时间尺度。类似的资源打孔、调 整方法同样适用于其他下行信号(以不同的子载波间隔)与随机接入资源重叠时进行调整的方式。
具体实现过程中，可以有下述几种情况(需要说明的是，本申请附图中“SS/PBCH”标识下行信号(下行同步信号块)，“PRACH”标识随机接入资源)：
(1)终端将与实际发送的下行信号时间位置重合的随机接入资源打孔。
本实施方式中，终端将与实际发送的下行信号时间位置重合的随机接入资源所在时隙中，与实际发送的下行信号时间位置重合的随机接入资源打孔，其他随机接入资源保留，还可以作为实际可用的随机接入资源继续用来发送随机接入前导。
例如实际传输的下行信号占用时域上第i个到第i+3个OFDM符号，那么时域上位于第iK个到第iK+4K-1个OFDM符号的随机接入资源确定为不使用(例如被打孔)。其中，K标识随机接入资源子载波间隔与下行信号子载波间隔之间的倍数，例如K可以是下述任一种：1/4、1/2、1、2、4。i为大于或等于0的整数。
图4为本申请提供的一种资源结构示意图。如图4所示，K＝2时，假设下行信号子载波间隔为15千赫兹(15kHz)、随机接入资源子载波间隔为30kHz。
一个随机接入资源所在时隙的时间长度内，最多可以传1个下行信号，具体可以是下行信号集中的任意1个下行信号。如图4所示，实际发送的下行信号占用时隙中第2～5个OFDM符号，位于随机接入资源时间尺度上的时隙中第12～13个OFDM符号可以放置随机接入资源。
再举例说明，假设实际发送的下行信号占用时隙中第8～11个OFDM符号，位于随机接入资源时间尺度上的时隙中第10～13个OFDM符号可以放置随机接入资源。
图5为本申请提供的另一种资源结构示意图。如图5所示，K＝1/2时，假设下行信号子载波间隔为30kHz、随机接入资源子载波间隔为15kHz。
此时，一个随机接入资源所在的时隙时间长度内，最多可以传4个下行信号，记为下行信号0～3，可以为下行信号集中的任意4个下行信号。
如图5所示，实际发送的下行信号占用时隙中的第2～5和/或第8～11个OFDM符号时，位于随机接入资源时间尺度上的时隙中第10～13个OFDM符号可以放置随机接入资源。
又例如，下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第6～13个OFDM符号可以放置随机接入资源。
下行信号1、下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙中第3～13个OFDM符号可以放置随机接入资源。
或者，实际发送的下行信号占用时隙中的第2～5或6～9个OFDM符号时，位于随机接入资源时间尺度上的时隙中第10～13个OFDM符号可以放置随机接入资源。
下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙中第5～13个OFDM符号可以放置随机接入资源。
下行信号1、下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙中第3～13个OFDM符号可以放置随机接入资源。
需要说明的是，如果随机接入资源配置基于非时隙调度，则没有被传输的下行信号所在的非时隙可以放置随机接入资源。例如，基于7个OFDM符号(在随机接入资源子载波间隔对应的时间尺度上)的非时隙调度，在下行信号1没有被传输而下行信号2被传输时， 该下行信号所在的时间资源的第3～6个OFDM符号可以用于放置随机接入资源。或者则在下行信号0和1没有被传输而下行信号2被传输时，该下行信号所在的时间资源的第0～6个OFDM符号可以用于放置随机接入资源。
又如假设下行信号子载波间隔为120kHz、随机接入资源子载波间隔为60kHz。此时，一个随机接入资源所在的时隙时间长度内，最多可以传4个下行信号，例如记为下行信号0～3，可以对应下行信号集中的任意4个下行信号。
例如下行信号传输的位置分别为两个相邻(下行信号时间尺度的)时隙中的第4～7、8～11、16～19、20～23个OFDM符号，则当下行信号2被传输而下行信号3没有被传输时，位于随机接入资源时间尺度上时隙的第10～13个OFDM符号可以放置随机接入资源。
当下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第6～13个OFDM符号可以放置随机接入资源。
当下行信号1、下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙k的第4～13个OFDM符号可以放置随机接入资源。
如果随机接入资源配置基于非时隙(即所配置的至少一个随机接入资源在时间上所占的OFDM符号小于一个时隙或者14个OFDM符号，例如随机接入资源占2/4/7个OFDM符号。所述OFDM符号的时间尺度可以与随机接入资源的时间尺度相同或者不相同。)调度，则没有被传输的下行信号所在的非时隙可以放置随机接入资源。具体地，基于7个OFDM符号(在随机接入资源子载波间隔对应的时间尺度上)的非时隙调度，则在下行信号1没有被传输而下行信号2被传输时，该下行信号所在的时间资源第4～6个OFDM符号可以用于放置随机接入资源。
或者则在下行信号0～1没有被传输而下行信号2被传输时，该下行信号所在的时间资源第0～6个OFDM符号可以用于放置随机接入资源。
或者，假设下行信号子载波间隔为240kHz、随机接入资源子载波间隔为120kHz。此时，一个随机接入资源所在的时隙时间长度内，最多可以传4个下行信号，例如记为下行信号0～3，可以对应下行信号集中的任意4个下行信号。
例如4个下行信号传输的位置分别为两个(下行信号时间尺度的)时隙中的8～11、12～15、16～19、20～23个OFDM符号，则当下行信号2被传输而下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第10～13个OFDM符号可以放置随机接入资源。
当下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第8～13个OFDM符号可以放置随机接入资源。
当下行信号1、下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙k的第6～13个OFDM符号可以放置随机接入资源。
如果随机接入资源配置基于非时隙调度，则没有被传输的下行信号所在的非时隙可以放置随机接入资源。例如，基于7个OFDM符号(在随机接入资源子载波间隔对应的时间尺度上)的非时隙调度，在下行信号1没有被传输而下行信号2被传输时，该下行信号所在的时间资源第6个OFDM符号可以用于放置随机接入资源；或者在下行信号0～1没有被传输而下行信号2被传输时，该下行信号所在的时间资源第0～6个OFDM符号可以用于放置随机接入资源。
或者，4个下行信号传输的位置分别为两个(下行信号时间尺度的)时隙中的4～7、 8～11、12～15、16～19个OFDM符号，则当下行信号2被传输而下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第8～13个OFDM符号可以放置随机接入资源。
当下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙的第6～13个OFDM符号可以放置随机接入资源。
当下行信号1、下行信号2和下行信号3没有被传输时，位于随机接入资源时间尺度上的时隙k的第4～13个OFDM符号可以放置随机接入资源。
如果随机接入资源配置基于非时隙调度，则没有被传输的下行信号所在的非时隙可以放置随机接入资源。例如，基于7个OFDM符号(在随机接入资源子载波间隔对应的时间尺度上)的非时隙调度，在下行信号1～2没有被传输而下行信号3被传输时，该下行信号所在的时间资源第4～6个OFDM符号可以用于放置随机接入资源；或者在下行信号0～2没有被传输而下行信号3被传输时，该下行信号所在的时间资源第0～6个OFDM符号可以用于放置随机接入资源。
图6为本申请提供的另一种资源结构示意图。如图6所示，K＝1，即下行信号子载波间隔和随机接入资源子载波间隔相同，均可以为15kHz、30kHz、120kHz中的任意一种。
一个随机接入资源所在的时隙时间长度内，最多可以传2个下行信号，例如记为下行信号0～1，可以对应下行信号集中的任意2个下行信号。
如图6所示，第一个实际发送的下行信号0占用时隙中的第2～5个OFDM符号。此时如果时隙内的下行信号1没有被传输，则该下行信号所在的时隙尾部第6～13个OFDM符号中可以放置随机接入资源。再例如，第一个下行信号0占用时隙中的第4～7个OFDM符号。此时如果时隙内的下行信号1没有被传输，则该下行信号所在的时隙尾部第8～13个OFDM符号中可以放置随机接入资源。
如果随机接入资源配置基于非时隙调度(指小于14个OFDM符号，例如2/4/7个OFDM符号)，则没有被传输的下行信号所在的非时隙(OFDM符号位置)可以放置随机接入资源。特别地，以基于7个OFDM符号的非时隙调度为例，在下行信号0没有被传输而下行信号1被传输时，该下行信号所在的时间资源的第0～6个OFDM符号可以用于放置随机接入资源。
再一种可能性中，K＝1/4，假设下行信号子载波间隔为240kHz、随机接入资源子载波间隔为60kHz。
此时，一个随机接入资源所在的时隙时间长度内，最多可以传8个下行信号，例如记为下行信号0～7，可以对应下行信号集中的任意8个下行信号。
例如8个下行信号传输的位置分别为4个(下行信号时间尺度的)时隙中的8～11、12～15、16～19、20～23、32～35、36～39、40～43、44～47个OFDM符号，则当下行信号6被传输而下行信号7没有被传输时，位于随机接入资源时间尺度上的时隙的第11～13个OFDM符号可以放置随机接入资源。
当下行信号5被传输而下行信号6～7没有被传输时，位于随机接入资源时间尺度上的时隙的第10～13个OFDM符号可以放置随机接入资源。
当下行信号4被传输而下行信号5～7没有被传输时，位于随机接入资源时间尺度上的时隙的第9～13个OFDM符号可以放置随机接入资源。
当下行信号3被传输而下行信号4～7没有被传输时，位于随机接入资源时间尺度上的 时隙的第7～13个OFDM符号可以放置随机接入资源。
当下行信号2被传输而下行信号6～7没有被传输时，位于随机接入资源时间尺度上的时隙的第5～13个OFDM符号可以放置随机接入资源。
当下行信号1被传输而下行信号2～7没有被传输时，位于随机接入资源时间尺度上的时隙的第4～13个OFDM符号可以放置随机接入资源。
当下行信号1被传输而下行信号1～7没有被传输时，位于随机接入资源时间尺度上的时隙的第3～13个OFDM符号可以放置随机接入资源。
如果随机接入资源配置基于非时隙调度，则没有被传输的下行信号所在的非时隙可以放置随机接入资源。例如，基于7个OFDM符号(在随机接入资源子载波间隔对应的时间尺度上)的非时隙调度，在下行信号3没有被传输而下行信号4～7中任意一个被传输时，该下行信号所在的时间资源第5～6个OFDM符号可以用于放置随机接入资源；或者在下行信号2～3没有被传输而下行信号4～7中任意一个被传输时，该下行信号所在的时间资源第4～6个OFDM符号可以用于放置随机接入资源；或者在下行信号1～3没有被传输而下行信号4～7中任意一个被传输时，该下行信号所在的时间资源第3～6个OFDM符号可以用于放置随机接入资源；或者在下行信号0～3没有被传输而下行信号4～7中任意一个被传输时，该下行信号所在的时间资源第0～6个OFDM符号可以用于放置随机接入资源。
(2)终端将与实际发送的下行信号时间位置重合的随机接入资源、以及与该实际发送的下行信号时间位置重合的随机接入资源所在时隙中与实际发送的下行信号时间位置重合的随机接入资源之前所有随机接入资源打孔。
图7为本申请提供的另一种资源结构示意图。如图7所示，假设K＝1。
除了确定不在与实际发送的下行信号时间位置重合的随机接入资源发送随机接入前导，还确定本时隙中这部分重合的随机接入资源之前的随机接入资源也不发送随机接入前导。
需要说明的是，发送随机接入前导是上行的，而下行信号是网络设备下行发送的，将本时隙中这部分重合的随机接入资源之前的随机接入资源也打孔，可以避免上下行的频繁切换。
(3)终端将与实际发送的下行信号时间位置重合的随机接入资源所在时隙中所有随机接入资源打孔。
图8为本申请提供的另一种资源结构示意图。如图8所示，假设K＝2。
与(2)类似，为了更好地避免上下行频繁切换，确定与实际发送的下行信号时间位置重合的随机接入资源所在时隙都不发送随机接入前导。
需要说明的是，网络设备确定合计可用的随机接入资源的方式，可以参照终端侧执行，不再赘述。
在上述实施例的基础上，因为原来的一部分随机接入资源不用了，那么一种实施方式中，需要增加实际可用的随机接入资源。
可选地，可以先根据下行或上行帧结构配置、以及时隙格式配置信息(slot format information)，确定随机接入配置周期内可用的上行时隙以及没有放置随机接入资源的上行OFDM符号位置。
进而可以根据打孔的随机接入资源数量，确定增加的实际可用的随机接入资源，具体 可以是确定增加的实际可用的随机接入资源的时间位置、频域数量等。所述增加的随机接入资源所在的时间位置可以是半静态配置的上行子帧、半静态配置的上行时隙、半静态配置的上行OFDM符号中的至少一种。在另外的实现方式中，所述增加的随机接入资源所在的时间位置可以是半静态配置未定上行或者下行子帧/时隙/OFDM符号。所述未定上行或者下行子帧/时隙/OFDM符号又称为unknown子帧/时隙/OFDM符号，是指在随机接入时没有确定该子帧/时隙/OFDM的方向是上行或者下行，或者是指在该子帧/时隙/OFDM的上行或者下行方向由RRC、MAC CE或者DCI信令动态配置或者调度。
相应地，网络设备也会采用跟终端相同的方式确定增加的实际可用的随机接入资源的时间位置、频域数量等。以确保在哪些随机接入资源上接收随机接入前导。
具体实现时，可以在时域、频域、其他上行OFDM符号位置增加随机接入资源。
1)一种可选方案中，终端在除被打孔的随机接入资源所在上行时隙以外的上行时隙增加实际可用的随机接入资源。
例如，终端在被打孔的随机接入资源所在上行时隙的相邻上行时隙，增加新的随机接入资源作为实际可用的随机接入资源。例如，在被打孔的随机接入资源所在上行时隙之前的第K1个上行子帧/时隙/OFDM符号增加随机接入资源；再例如在被打孔的随机接入资源所在上行时隙之前的第K2个上行子帧/时隙/OFDM符号增加随机接入资源，所述K1和K2为非负整数。可选地，K1和K2为预设值或者根据预设定规则确定的值，例如固定为1个时隙。可选地，增加的随机接入资源数量与被打孔的随机接入资源数量不一样，例如更多。可选地，增加的随机接入资源数量与被打孔的随机接入资源数量不一样，例如更少。可选地，根据可用的上行子帧/时隙/OFDM符号数量确定增加的随机接入资源数量。
图9为本申请提供的又一种资源结构示意图；图10为本申请提供的另一种资源结构示意图。
如图9、图10所示，被打孔的随机接入资源所在上行时隙的相邻上行时隙中，没有下行信号传输，确定这个时隙中部分或全部来传输随机接入前导。
2)另一种可选地方案中，终端在与实际发送的下行信号位置不重合随机接入资源所在上行时隙的频域上，增加新的随机接入资源作为实际可用的随机接入资源。
图11为本申请提供的又一种资源结构示意图；图12为本申请提供的另一种资源结构示意图。
如图11、12所示，在频域上增加随机接入资源，新增加的随机接入资源在时间上也不与实际发送的下行信号重合。
可选地，频域上增加的随机接入资源数量不超过网络设备配置的信道带宽或者初始上行接入带宽。
3)再一种可选地方案中，终端在与实际发送的下行信号位置不重合随机接入资源所在上行时隙的其他OFDM符号中，增加新的随机接入资源作为实际可用的随机接入资源。可选地，根据可用的上行子帧/时隙/OFDM符号数量确定增加的随机接入资源数量。
图13为本申请提供的又一种资源结构示意图；图14为本申请提供的另一种资源结构示意图。
如图13、14所示，在被打孔的随机资源所在时隙的其他OFDM符号中，增加新的随机接入资源作为实际可用的随机接入资源。
可选地，增加的随机接入资源可以在时域上均匀分布于随机接入配置周期内的其它上行时隙或OFDM符号位置上，在此不作限制。
4)一种可选地方案中，网络设备可以指示增加的随机接入资源所在的上行时间位置，终端在网络设备指示的上行时间位置增加随机接入资源。
其中，网络设备指示的随机接入资源所在的上行时间位置，可以是备用的随机接入资源，在实际发送的下行信号与随机接入资源有重合，或者一个随机接入配置周期内与实际发送的下行信号重合的随机接入资源数量大于第一预设阈值时，或者实际发送的下行信号大于第二预设阈值时，激活备用的随机接入资源。
需要说明的是，以上4种增加随机接入资源的方案可以配置不同的标识，例如用2个bit来标识，网络设备在配置信息中携带“增加随机接入资源的方案”标识，以便终端知道采用哪种方案增加随机接入资源。
另外，终端在新增加的随机接入资源上发送随机接入前导时，与之前的发送方法相同，在此不作限制。
可选地，在确定将部分随机接入资源打孔后，还可以调整随机接入配置周期：
一种方式中，将原来N个随机接入配置周期内的随机接入资源，调整成M个新的随机接入配置周期，N和M可以为任意大于0的整数。在新的随机接入配置周期内，不再有与下行信号重叠的随机接入资源。
可选地，调整前N个随机接入配置周期内总的随机接入资源数量大于调整后M个新的随机接入配置周期内总的随机接入资源数量。或者，
调整前N个随机接入配置周期内总的随机接入资源数量等于调整后M个新的随机接入配置周期内总的随机接入资源数量。或者，
调整前N个随机接入配置周期内总的随机接入资源数量小于调整后M个新的随机接入配置周期内总的随机接入资源数量。
可选地，调整前的一个随机接入配置周期内总的随机接入资源数量大于调整后的一个新的随机接入配置周期内总的随机接入资源数量；或者，
调整前的一个随机接入配置周期内总的随机接入资源数量等于调整后的一个新的随机接入配置周期内总的随机接入资源数量；或者，
调整前的一个随机接入配置周期内总的随机接入资源数量小于调整后的一个新的随机接入配置周期内总的随机接入资源数量。
需要说明的是，上述调整随机接入配置周期可以包括增加和/或打孔随机接入资源。
图15为本申请提供的又一种资源结构示意图。如图15所示，先确定实际传输的下行信号，即第一排中黑色部分。
进而通过增加和/或打孔随机接入资源，调整随机接入配置周期。
在上述实施例的基础上，S201之前，还可以根据实际发送的下行信号、实际发送下行信号的周期、一个随机接入配置周期内与实际发送的下行信号重合的随机接入资源数量中的一种或多种，确定调整随机接入资源的方式。
例如：一个随机接入配置周期内与实际发送的下行信号重合的随机接入资源数量大于第一预设阈值时，确定增加随机接入资源。具体增加方式可以参见前述图9～图14所示的实施例，在此不再赘述。
或者，一个随机接入配置周期内与实际发送的下行信号重合的随机接入资源数量小于或等于第一预设阈值时，确定调整随机接入配置周期。
或者，在上述实施例的基础上，S201之前，终端还可以根据下行/上行帧结构配置、时隙格式配置信息、随机接入配置信息中的一种或多种，确定调整随机接入资源的方式。
需要说明的是，终端执行的调整，网络设备也要执行相应地调整，例如调整下行信号与随机接入资源的关联关系、调整随机接入配置周期等，在此不再赘述。
进一步地，终端根据实际可用的随机接入资源、以及下行信号与随机接入资源的关联关系，确定所述实际发送的下行信号对应的目标随机接入资源之前，还可以根据实际发送的下行信号、以及所述实际可用的随机接入资源，更新下行信号与随机接入资源的关联关系，获取新的下行信号与随机接入资源的关联关系。
即由于原来的部分随机接入资源被确定不可用，还可能增加了新的实际可用的随机接入资源，下行信号与随机接入资源的关联关系也需要适应性地更新调整。
调整之后，终端根据实际可用的随机接入资源、以及调整后的下行信号与随机接入资源的关联关系，确定实际发送的下行信号对应的目标随机接入资源。
具体地，可以将被打孔的随机接入资源原先关联的下行信号和/或下行信号组，关联到随机接入配置周期内剩余的随机接入资源。
或者，更新实际传输的下行信号中每个下行信号关联的随机接入资源数量。更新后，实际传输的下行信号中每个下行信号关联的随机接入资源数量小于原来每个下行信号关联的随机接入资源数量。
或者更新实际传输的下行信号中部分下行信号关联的随机接入资源数量。更新后，更新的这部分实际传输的下行信号关联的随机接入资源数量小于原来这部分实际传输的下行信号关联的随机接入资源数量。
或者，调整后的随机接入配置周期不变，在调整后的随机接入配置周期内的增加随机接入资源，调整每个或部分下行信号关联的随机接入资源的时间和/或频率位置。即将增加的实际可用的随机接入资源与每个或部分实际发送的下行信号关联。
或者，调整后的随机接入配置周期变长，根据调整后的随机接入配置周期内的随机接入资源，调整每个或部分下行信号关联的随机接入资源的时间和/或频率位置。
或者，调整后的随机接入配置周期变短，根据调整后的随机接入配置周期内的随机接入资源，调整每个或部分下行信号关联的随机接入资源的时间和/或频率位置。
