本申请主张在2017年11月17日在中国提交的中国专利申请号No.201711148879.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种资源映射方法、确定方法、网络侧设备及用户终端。
背景技术
相关技术中的通信协议不支持对于较大资源分配和较大的带宽配置下的分布式虚拟资源块(distributed VRB，DVRB)的资源映射，由于在5G中引入了更大的带宽和码块组(Code Block Group，CBG)传输，在较大的资源分配的情况下，需要在这种场景下支持DVRB映射。
在较小的资源分配和较大的带宽配置下，如长期演进(Long Term Evolution，LTE)中规定50物理资源块(physical resource block，PRB)以上，LTE支持采用尺度更小，按照小区带宽1/4量级的频率间隔的DVRB的映射，更小的频率间隔的应用允许将分布式传输限制在整个小区带宽的一部分。
在新空口(new radio，NR)中，由于上述的大资源分配和小资源分配的方案都同时存在需求，因此需要有一种融合的方案实现上述两种方案。
另外，由于NR对于预编码资源块组(Precoding Resource block Groups，PRG)的设计采用了type1和type2两种不同的类型，因此需要对于这种类型分开设计不同的DVRB的映射方案，并且确定其DVRB映射的交织器的具体参数。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完成地描述，显然，所描述的实施例仅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付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。
网络侧设备在决定将哪些资源块(resource block，RB)分配给某个特定用户终端(User Equipment，UE)时，可能会将时域和频域相关的下行信道质量考虑在内。即信道相关的频选调度会将信道的变化，如由频率选择性衰落引起的信道变化等，考虑在内，然后将那些信道质量好的RB(不一定连续)分配给该UE，这样可能会显著地提升UE的速率以及整个小区的吞吐量。
然而频选调度要求UE上报下行信道质量给网络侧设备，这会带来较大的信令开销，同时需要保证网络侧设备能够成功并及时地接收到下行信道质量信息，以避免收不到或收到过时的信息。因此在某些场景下，频选调度是不适用的，例如：对于低速业务，如语音业务，与频选相关的反馈信令会带来相对较大的开销，得不偿失；在UE高速移动的场景下，如在高速运行的高铁上，很难或根本不可能跟踪实时信道质量，因而无法提供频选调度所需的信道质量精确度。
在这种情况下，一种可选的方案是将下行传输分布到频域内非连续的资源块上以获得频率分集增益，从而提高传输的可靠性。
为了实现上述两种不同目的的资源映射，引入了PRB和虚拟资源块(virtual resource block，VRB)的概念。其中PRB表示物理资源块，VRB表示虚拟资源块，网络侧设备一般通过VRB给用户终端指示资源信息，具体的物理资源映射需要通过VRB映射到对应PRB后才能得到，一般集中式PRB表示一个用户终端的资源占用连续的PRB，分布式PRB表示一个用户终端占用带宽上不连续的PRB资源，这样可以提高系统的频率分集增益，提高抗干 扰能力
在LTE中，定义了2种类型的VRB：集中式VRB(localized VRB，LVRB)和分布式VRB(distributed VRB，DVRB)。
在集中式的资源映射方式中，VRB对和PRB对是一一对应的，即VRB的位置就是PRB的位置，RB资源块编号n PRB＝n VRB，范围是
Figure PCTCN2018109976-appb-000005
Figure PCTCN2018109976-appb-000006
下行的VRB的资源块数目，n pRB为下行PRB的编号；
在分布式的资源映射方式中，VRB对和PRB对不是一一对应的，连续的VRB编号将映射到不连续的PRB编号上，并且一个子帧内的2个时隙也有着不同的映射关系，如图1所示，通过这种方法来达到“分布式”的资源分配。无论是将连续的VRB对映射到不连续的PRB对上，还是分开每个PRB对，使一个PRB对的两个RB的资源传输带有一定的频率间隔(可以看成基于时隙(slot)的跳频)，目的都是为了达到频率上的分集效应。
值得注意的是，并不是所有的VRB都可以用来进行交织的，如果用n VRB来表示VRB的频率位置，那么可以用来交织的VRB的范围是
Figure PCTCN2018109976-appb-000007
只有该范围内的VRB才可以进行RB对的交织，才可以进行分布式的VRB资源分配。这么做的主要目的是为了保证在有多种资源分配方式的不同用户终端复用资源的时候，减少资源冲突的可能性，即将分布式的资源集中在某一些物理资源上。
如图1所示，如果n VRB的范围是0～10，那么网络侧设备进行分布式资源调度时，RB的编号可能分配到0～10这11个VRB。注意这里的参数
Figure PCTCN2018109976-appb-000008
不是下行带宽的RB个数
Figure PCTCN2018109976-appb-000009
参数
Figure PCTCN2018109976-appb-000010
计算根据LTE的协议如下：
(1)如果采用时隙GAP1，则
Figure PCTCN2018109976-appb-000011
Figure PCTCN2018109976-appb-000012
比如当前是5MHz带宽，
Figure PCTCN2018109976-appb-000013
则
Figure PCTCN2018109976-appb-000014
Figure PCTCN2018109976-appb-000015
如果是10MHz带宽，
Figure PCTCN2018109976-appb-000016
则
Figure PCTCN2018109976-appb-000017
因此对于10MHz带宽来说，采用频率间隔GAP1时只有46个VRB对才可以进行RB的频率交织，才能进行分布式的RB分配。
(2)如果采用GAP2，则
Figure PCTCN2018109976-appb-000018
比如当前是10MHz带宽，
Figure PCTCN2018109976-appb-000019
则
Figure PCTCN2018109976-appb-000020
Figure PCTCN2018109976-appb-000021
因此对于10MHz带宽来说，采用频率间隔GAP2时只有36个VRB对才可以进行RB的频率交织，才能进行分布式的RB分配。
其中
Figure PCTCN2018109976-appb-000022
和
Figure PCTCN2018109976-appb-000023
分别由表1定义：
表1 (从TS36.211第6.2.3.2章节)
Figure PCTCN2018109976-appb-000024
一般来说会使用交织器来完成VRB到PRB的映射，并且为了实现DVRB，即使得映射后的资源尽可能分散，要求映射后的逻辑资源尽可能在整个物理资源上都均匀分布开。
Block interleaver(块状交织)可以用来完成这个过程，通过将VRB从行写入，从列读出完成VRB的重新排序和打乱。对于块状交织器最重要的两个参数是要确定其行数目和列数目。
在LTE的设计中，如前面所述，由于经过DVRB映射后的资源会分布到整个带宽上，会在一定程度上造成资源的碎片化，因此有必要限制资源映射大带宽。
因此在4G LTE的设计中规定了如下的原则：
(1)如果下行控制信息(Downlink Control Information，DCI)format(格式)1A/1B/1D使用分布式VRB分配方式，且其DCI的循环冗余校验(Cyclic Redundancy Check，CRC)由小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)加扰，则当下行带宽为6～49RB时，分配给 对应UE的VRB数可以从1个到最多
Figure PCTCN2018109976-appb-000025
个，这个值很接近系统带宽，在协议中有具体规定；然而当下行带宽为50～110RB时，分配给对应UE的VRB数可以从1个到最多16个。
(2)分布式的VRB到PRB映射，要避免连续分配的RB长度大于一半系统带宽，这样会导致资源的碎片化。
举例如下：
如在50PRB的配置下，当配置成GAP1和GAP2时候，前16个VRB映射后的资源情况如图2所示，其中的数字是VRB的逻辑编号。
LTE中由于DVRB还使用了intra-subfame hopping，也即是在一个subframe里面的两个slot使用了跳频，因此图2中画出了前后两个slot的映射。可以看到，GAP1的DVRB映射和GAP2的DVRB映射的主要区别在于映射后的资源的分布带宽。GAP1的分布带宽等于系统带宽，GAP2的分布带宽约为系统带宽的1/2的量级。
PRB bundling即物理资源块绑定。LTE中为了提高信道估计的质量，假定多个PRB使用相同的Precoder(赋形向量)，这样接收端(也就是用户终端侧)可以将多个PRB联合起来做信道估计，在LTE中这样的配置叫做预编码资源块组(Precoding Resource block Groups，PRG)配置。
UE可以假定在一个服务小区下时，预编码粒度是频域中的多个资源块(PRB)。预编码资源块组(PRGS)大小划分依据系统带宽和，并且PRG是由连续的PRB组成。UE可以假设在一个PRG中，所有预定的PRB适用相同的Precoder。PRG的大小和系统的带宽相关，LTE中规定如表2所示：
表2
Figure PCTCN2018109976-appb-000026
其中，P′为一个PRG中包含的PRB的数目，即PRG size(大小)。
在LTE的在类型0的资源分配中，分配给UE的资源由位图(bitmap) 来表示，其中位图中的每一位代表一个资源块组，也就是RBG，置1表示相应的资源块分配给了此UE，0则表示未分配。资源块组RBG是由一个或多个连续的VRB组成，VRB是集中类型的，RBG的大小P(包含的RB数目)与系统带宽有关，如表3所示：
表3
Figure PCTCN2018109976-appb-000027
5G NR中的PRG配置可能有两种类型:type 1和type 2，其中，type 1是指由所述网络侧设备配置或者预定义一组PRG size的集合，比如，[1,2,4,8,16],通过L1信令动态指示所述用户终端使用的PRG size；type 2是指PRG size等于被连续调度的资源的数目。
NR中资源支持两种类型的资源分配，bitmap类型(type 0)和连续资源分配类型(type 1)。
类型0：类型0用bitmap的形式，因为bitmap的每个比特都代表一个RBG(resource block group),RBG代表一个RB组，RB组的大小可能与带宽有关，比如20M的系统带宽，每个RBG包括4个RB，这样20M带宽一共有25个RBG，对应的DCI中的bitmap就有25比特。如果将某个RBG分配给UE，就在UE对应的DCI的bitmap对应比特置1就可以了。
类型1：分配给UE的资源为一段连续的VRB，其VRB到实际物理资源PRB的映射可以是集中式(localized)，也可以是分布式的(distributed)。
相关技术中的协议不支持对于较大资源分配和较大的带宽配置下的DVRB的资源映射，由于在5G中引入了更大的带宽和CBG传输，在较大的资源分配的情况下，需要在这种场景下支持DVRB映射。
由于NR对于PRG的设计采用了type1和type2两种不同的类型，因此 需要对于这种类型分开设计不同的DVRB的映射方案，并且确定其DVRB映射的交织器的具体参数。
本公开要解决的技术问题是提供一种资源映射方法、确定方法、网络侧设备及用户终端，能够满足type1和type2两种不同的PRG类型的资源映射需要。
本公开实施例提供了一种资源映射方法，应用于网络侧设备，如图3所示，包括：
步骤101：确定物理下行控制信道的资源映射配置信息；
步骤102：根据所述资源映射配置信息将虚拟资源块映射到物理资源块，并将所述资源映射配置信息发送给用户终端，以使所述用户终端利用所述资源映射配置信息中的配置参数获知资源分散映射后所占用的带宽；
其中，所述资源映射配置信息中的配置参数包括以下至少一个：
下行带宽的可用虚拟资源块VRB数目
Figure PCTCN2018109976-appb-000028
相邻VRB映射到对应的物理资源块PRB后的频率间隔；
用户终端所在的传输带宽；
调度的数据所占带宽。
本实施例中，网络侧设备向用户终端发送物理下行控制信道的资源映射配置信息，在该资源映射配置信息中携带有配置参数，用户终端可以根据资源映射配置信息中的配置参数确定资源分散映射后所占用的带宽，进而在所确定的带宽上接收下行数据，本公开的技术方案能够满足type1和type2两种不同的PRG类型的资源映射需要，在保证了资源的分集增益的同时，提高了资源的可用性，保证了资源的连续性。
在DVRB的映射过程中，一般需要确定以下参数：
(1)块状交织器(Block interleaver)的交织颗粒度(N unit)，一般来说是P′或者P′的倍数。所有的VRB以N unit为颗粒度分为
Figure PCTCN2018109976-appb-000029
组；
(2)确定交织矩阵的列数目(或者行数目)，也就是N col，块状交织器的列数目。对
Figure PCTCN2018109976-appb-000030
组应用Block interleaver，即通过将VRB从行写入，从列读出完成VRB的重新排序和打乱，或者VRB从列写入，从行读出完成VRB的重新排序和打乱。
上述交织后的逻辑资源映射到物理资源，一般来说，由于经过DVRB映射后的资源会分布到整个带宽上，会在一定程度上造成资源的碎片化，因此有必要限制资源映射大带宽。此时对于
Figure PCTCN2018109976-appb-000031
的数目也会有一定的限制。
本实施例中，所述资源映射配置信息包括从VRB编号到PRB编号的映射函数或其编号f(·)，n PRB＝f(n VRB,n s)，所述映射函数f(·)的自变量至少包括VRB编号和时隙编号，其中，VRB编号的取值范围为
Figure PCTCN2018109976-appb-000032
n PRB的取值也有一定范围，不能超出物理资源数目的限制，从
Figure PCTCN2018109976-appb-000033
n s是slot的编号，此处引入slot编号作为自变量，是允许slot之间的随机化；另外，对于不同的
Figure PCTCN2018109976-appb-000034
N unit，N col，f(·)映射的结果也会有所不同。
当
Figure PCTCN2018109976-appb-000035
接近于总的物理资源
Figure PCTCN2018109976-appb-000036
的时候，可利用的物理资源较多。但是由于资源分散映射后在物理上的频域间隔较小，因此分集的增益较小；当
Figure PCTCN2018109976-appb-000037
远小于总的物理资源
Figure PCTCN2018109976-appb-000038
的时候，可利用的物理资源较少，但是由于资源分散映射后在物理上的频域间隔较大，因此分集的增益较大。
具体实施例一中，通过协议或者通过网络侧设备的无线资源控制(Radio Resource Control，RRC)信令，在一组DVRB的映射方式(对应不同的映射带宽)中通知其中的一种UE的DVRB映射方式，所述将所述资源映射配置信息发送给用户终端包括：
通过RRC信令将所述资源映射配置信息发送给所述用户终端，以使所述用户终端从多个资源映射配置方式中选择一资源映射配置方式，还可以是通过RRC信令将所述资源映射配置信息的编号发送给所述用户终端，以使所述用户终端从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式或为预先发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式包括对应的映射函数和VRB编号取值范围。
本实施例的背景是网络侧设备可以半静态的控制DVRB的映射方式，比如网络侧设备控制DVRB映射后的离散的程度，也就是映射后的占据的带宽的大小，从而有效控制资源的碎片化的情况。具体的实现可以如下：
网络侧设备通过RRC信令通知UE具体的DVRB的映射方式，如当收到RRC信令i时候，采用f i(·)映射函数；其中，f i(·)可以有不同的函数形式，比 如f i(·)对应的DVRB映射后的带宽可以是不同(如全带宽或1/2带宽，对应不同的应用场景)，以及不同或者相同的n VRB取值范围(对应较小的资源分配和较大的带宽配置的场景)。
具体实施例二中，通过协议或者通过网络侧设备的RRC信令配置一组UE的DVRB映射方式(对应不同的映射带宽)，之后通过L1信令选择一个DVRB的映射方式，所述将所述资源映射配置信息发送给用户终端包括：
通过L1信令将所述资源映射配置信息发送给所述用户终端，以使所述用户终端从多个资源映射配置方式中选择一资源映射配置方式，还可以是通过L1信令将所述资源映射配置信息的编号发送给所述用户终端，以使所述用户终端从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式或为通过RRC信令发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式包括对应的映射函数和VRB编号取值范围。
本实施例的背景是网络侧设备可以动态的控制DVRB的映射方式，比如网络侧设备控制DVRB映射后的离散的程度，也就是映射后的占据的带宽的大小，从而有效控制资源的碎片化的情况。具体的实现可以如下：网络侧设备通过RRC信令通知UE一组DVRB的映射方式或者由协议规定一组DVRB的映射方式，通过L1的动态信令通知具体采用了哪一种映射方式，如当收到L1信令i时候，采用f i(·)映射函数；其中，f i(·)可以有不同的函数形式，比如f i(·)对应的DVRB映射后的带宽可以是不同(如全带宽或1/2带宽，对应不同的应用场景)，以及不同或者相同的n VRB取值范围(对应较小的资源分配和较大的带宽配置的场景)。
具体实施例三中，用户终端可以根据实际调度的资源的带宽，在一组DVRB映射方式(对应不同的映射带宽)中隐式确定一种DVRB的映射方式，实际调度的资源的带宽即调度的数据所占带宽有别于传输带宽，是指实际调度使用了多少带宽，所述将所述资源映射配置信息发送给用户终端包括：
将被调度的资源块的数目通知给所述用户终端，以便所述用户终端根据所述被调度的资源块的数目从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式或为通 过RRC信令发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式包括对应的映射函数和VRB编号取值范围且每一资源映射配置方式对应一被调度的资源块的数目。
上述的具体实施例一和二中的DVRB都是在一个带宽中进行的资源分散化的操作，本实施例的资源分散化只在被调度的那些资源中进行。为了便于理解，两者的差别如图4和图5所示，图中带点的是调度的VRB，在调度带宽内的DVRB指的是在该VRB所对应的PRB资源集合内将各个PRB的顺序进行打乱，这在某些情况下能够使得基于CBG传输的数据传输的性能得到优化，并且又不至于使得资源碎片化。
具体的实现可以如下：网络侧设备通过RRC信令通知UE一组DVRB的映射方式或者由协议规定一组DVRB的映射方式，终端根据被调度到的资源的数目(通常是VRB的数目)来动态的确定采用了哪一种映射方式，例：
当被调度的资源的数目小于等于一定值时候，采用f 1(·)；
当被调度的资源的数目大于一定值时候，采用f 2(·)；
f 1(·)和f 2(·)有不同的函数形式：
其中f 1(·)和f 2(·)对应的DVRB映射后的带宽可以是不同(如全带宽或1/2带宽，对应不同的应用场景)；或者f 1(·)对应的DVRB是在给定带宽下的分散化，f 2(·)对应的DVRB是在调度带宽内分散化；不同或者相同的n VRB取值范围(对应较小的资源分配和较大的带宽配置的场景)。
具体实施例四中，可以根据配置的可能传输带宽(BWP带宽或者载波的带宽)，在一组DVRB映射方式(对应不同的映射带宽)中隐式确定一种DVRB的映射方式，所述将所述资源映射配置信息发送给用户终端包括：
将为所述用户终端分配的带宽部分BWP的配置发送给所述用户终端，以便所述用户终端根据所述BWP的配置从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式或为通过RRC信令发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式包括对应的映射函数和VRB编号取值范围且每一资源映射配置方式对应一BWP的配置。
具体的实现可以如下：网络侧设备通过RRC信令通知UE一组DVRB的 映射方式或者由协议规定一组DVRB的映射方式，终端根据BWP带宽来动态的确定采用了哪一种映射方式，例如对于采用f i(·)映射函数；f i(·)可以有不同的函数形式：
f i(·)对应的DVRB映射后的带宽可以是不同(如全带宽或1/2带宽，对应不同的应用场景)；
或者f i(·)对应的DVRB是在给定带宽下的DVRB或者在调度带宽内的DVRB可选择；
不同或者相同的n VRB取值范围(对应较小的资源分配和较大的带宽配置的场景)。
具体实施例五中，可以根据BWP带宽和资源分配的类型(如type0或type1)，在一组DVRB映射方式(对应不同的映射带宽)中隐式确定一种DVRB的映射方式，所述将所述资源映射配置信息发送给用户终端包括：
将为所述用户终端分配的BWP的配置和资源分配类型发送给所述用户终端，以便所述用户终端根据所述BWP的配置和所述资源分配类型从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式或为通过RRC信令发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式对应一BWP的配置和资源分配类型的组合。
具体的实现可以如下：对于NR下行资源分配类型0(bitmap类型)，DVRB是在给定被调度的资源上进行分散化，意即block interleaver只在被调度的VRB上面进行；
对于NR下行资源分配类型1(连续资源分配)，DVRB是在给定带宽下进行分散化，意即block interleaver在BWP带宽内或者一个已知的带宽内上面进行。
具体实施例六中，可以根据DCI format来确定DVRB的映射方式，所述将所述资源映射配置信息发送给用户终端包括：
通过下行控制信息将所述资源映射配置信息发送给所述用户终端，以便所述用户终端根据所述下行控制信息的格式从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射 配置方式或为通过RRC信令发送给所述用户终端的多个资源映射配置方式，每一资源映射配置方式对应一种格式的下行控制信息。
具体的实现可以如下：对于回退DCI和普通的DCI，两者的DCI格式不同，考虑采用不同的DVRB的映射方式。如：对于回退DCI，DVRB是在给定带宽下进行分散化，意即block interleaver在BWP带宽内或者一个已知的带宽内上面进行；对于普通的DCI，DVRB是在被调度的资源上进行分散化，意即block interleaver只在被调度的VRB上面进行。
进一步地，所述将所述资源映射配置信息发送给用户终端包括：
通过下行控制信息将所述资源映射配置信息发送给所述用户终端，以便所述用户终端根据所述下行控制信息的格式从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式中的资源分散映射后所占用的带宽为预分配的带宽或实际被调度的资源的带宽，其中预分配的带宽是由所述网络侧设备配置或者至少由如下的参数获知：
下行带宽的可用VRB数目

和/或
相邻VRB映射到对应的物理资源块PRB后的频率间隔；和/或
用户终端所在的传输带宽；和/或
调度的数据所占带宽。
具体实施例七中，在初始接入的时候，由于尚未有UE-specific的信令传达到终端，因此需要进行特殊的处理来确定具体使用DVRB映射。举例如下：当在初始接入的时候，网络侧设备发送fallback DCI(回退DCI)来传达控制信令，考虑采用固定的PRG type来简化流程；
当终端接收承载剩余系统信息(Remaining system information，RMSI)，message(消息)2(RAR(random access response))，message 4，其他系统信息(Other system information，OSI)的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)时候，并且终端使用DVRB的方式进行接收的时候，考虑采用如下的默认方式进行接收：
(1)DVRB是在给定带宽下进行分散化，意即block interleaver在初始接入的BWP带宽内进行；
(2)DVRB是在被调度的资源上进行分散化，意即block interleaver只 在被调度的VRB上面进行；
(3)可以根据实际调度的资源的带宽，在一组DVRB映射方式(对应不同的映射带宽)中隐式确定一种DVRB的映射方式，所述将所述资源映射配置信息发送给用户终端包括：将实际调度的资源的带宽值通知给所述用户终端，以便所述用户终端根据实际调度的资源的带宽值从多个资源映射配置方式中选择一资源映射配置方式，所述多个资源映射配置方式为预配置的多个资源映射配置方式，每一资源映射配置方式对应一带宽值。
其中，RMSI是5G NR中引入的类似于LTE中SIB1的系统信息。OSI是5G NR中引入的类似于LTE中除去SIB1以外的其余SIBx系统信息。
对于相关技术中的4G LTE物理层设计中物理随机接入(Physical Random Access Channel，PRACH)信道主要用于用户终端侧发起上行随机接入请求，使得网络侧设备侧根据其请求进一步决定后续的响应。
相关技术中的随机接入过程主要有4个步骤，如下：
步骤1：前导码发送(Message 1)
步骤2：随机接入响应(Message 2)
步骤3：层2/层3消息(Message 3)
步骤4：竞争解决消息(Message 4)
其中步骤1主要有物理层的Preamble(码)生成的序列(sequence)映射到物理层的时频资源后发送；步骤2主要是网络侧设备通过PDSCH信道发送随机接入响应(Random Access Response，RAR)，并用随机接入无线网络临时标识(Random Access Radio Network Temporary ID，RA-RNTI)加以识别，以识别在哪个时频时隙侦测到了接入前缀。如果因为几个UE在相同的前缀时频资源中选择了相同的标志而发生碰撞，这些UE也都会收到RAR；步骤3这是调度分配在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的第一个与随机接入相关的消息，这个消息携带了确定的随机接入过程消息，比如RRC连接请求消息、位置区更新消息，或者调度请求消息；步骤4主要目的是竞争解决消息，竞争解决消息是针对C-RNTI或者临时C-RNTI的。在后一种情况下，竞争解决消息回应的是L2/L3消息中携带的UE ID。竞争解决消息支持HARQ。如果竞争冲突发生之后，有一个L2/L3 消息被成功解码，则只有那个侦测到自己的UE ID(或者C-RNTI)的UE才会发HARQ反馈消息，而其它UE则意识到存在一个冲突，就不会发HARQ反馈消息，而是尽快结束这次接入过程，并开始一个新的随机接入。
