Description

一种通信方法及装置 技术领域
本申请实施例涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
在新无线(new radio，NR)通信系统的随机接入过程中，基站向用户设备(user equipment，UE)发送物理下行控制信道(physical downlink control channel，PDCCH)，该PDCCH用于调度物理下行共享信道(physical downlink shared channel，PDSCH)。基站在该PDSCH上发送随机接入响应(random access response，RAR)，RAR中携带用于调度用户设备发送的物理上行共享信道(physical uplink shared channel，PUSCH)的上行调度授权。
当用户设备的接收天线数少时会影响RAR的接收，通过基站重复多次发送PDCCH和用户设备多次接收PDCCH的方式来增强用户设备对PDCCH的接收效果，从而达到覆盖增强的效果，用户设备通过盲检测获取PDSCH上的无线资源控制(radio resource control，RRC)信令配置调度RAR的控制信道的最大重复次数，并且通过下行控制信息(downlink control information，DCI)确定具体重复次数，以实现覆盖增强。
不同天线数量或者不同接收能力的终端设备，需要通过固定的盲检测方法接收覆盖增强的配置信息，导致盲检测复杂度高、网络配置灵活性低，因此，亟需一种能够提高网络配置灵活性、提高通信效率的方法。

具体实施方式
下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。

本申请实施例提供了一种通信方法及装置，能够降低盲检测复杂度，并且节省网络资源。
终端设备，例如UE，随机接入网络设备，例如基站，过程包括基于竞争的随机接入和基于非竞争的随机接入，基站可以是4G基站eNB或者5G基站gNB，也可以是未来的其他通信架构。
请参阅图1所示的基于竞争的随机接入架构，步骤1：UE在物理随机接入信道(physicalrandom access channel，PRACH)上发送随机前导序列(random access preamble)，该步骤1通过消息1(Msg1)执行，基站通过检测Preamble获得preamble ID，即随机接入前导标识(random access preamble identifier，RAPID)。
步骤2：基站向UE发送随机接入响应(random access response，RAR)，步骤2通过Msg2执行，在发送随机接入响应之前先发送物理下行控制信道PDCCH，该PDCCH调度物理下行共享信道PDSCH。随机接入响应承载在该PDSCH上发送，RAR中携带基站估计的传输时延对应的时间提前量(timing advance，TA)，RAPID，(temporary cell-radio network tempory identity，TC-RNTI)，及用于第3步UE发送Msg3所需的上行(up link，UL)权限(Grant)。UE使用TA调整上行定时。
步骤3：根据RAR中UL Grant的调度发送预定传播信号(scheduled transmission)，步骤3由Msg3执行，其中Msg3携带用于冲突解决的UE的标识信息。
步骤4：基站在PDSCH上将竞争解决消息(contention resolution)发送给UE，步骤4由Msg4执行，该步骤解决了由于多个UE试图使用同一个随机接入资源和相同preamble接入时导致的竞争和冲突。
基于非竞争的随机接入架构请参阅图2，基于非竞争的随机接入使用基站通过随机前导序列指配(random access preamble assignment)发送的专用的随机接入资源和preamble，不存在竞争冲突，因此只需要执行上述步骤1和步骤2，不需要步骤3和步骤4。该专用的随机接入资源可以通过PRACH时频资源索引(Mask Index)指示。
在步骤2中，基站发送承载RAR的PDSCH给UE，RAR中携带Msg1中指示的传输时延对应的TA，RAPID，TC-RNTI，及用于Msg3发送的UL Grant。由于终端设备接收天线数的减少会导致覆盖小，从而导致影响到初始接入过程中RAR及Msg4的接收，因此需要接收做覆盖恢复，其中一个方面为RAR的覆盖恢复。终端设备可以包括降能力终端设备(reduced capability UE，REDCAP UE)，该REDCAP UE的天线数可以1根发射天线和1根接收天线(即1T1R)，或者1根发射天线和2根接收天线。另外，REDCAP UE的带宽以及发射天线数减少也会影响上行的覆盖，例如上行共享信道(physical uplink shared channel，PUSCH)的发送也需要做覆盖恢复。需要说明的是，本申请实施例中的覆盖恢复与覆盖增强的含义相同，可以等价替换，在此不再赘述。
在LTE的覆盖增强技术中，LTE中会配置PDCCH和PDSCH重复发送多次，来增强基站发送PDCCH和PDSCH的覆盖，提高UE成功接收的准确率。
1、通过重复发送多次PDCCH来增强PDCCH的覆盖。通过RRC信令配置调度RAR的控制信道的最大重复次数(R max)，并且在DCI格式(format)6-1A中指示具体重复次数，具体如下：
RRC信令(physical downlink control channel，MPDCCH)mpdcch-重复次数(NumRepetiton)-RA中配置调度RAR的PDCCH的最大重复次数；
通过DCI format 6-1A中的字段DCI重复次数子帧(subframe repetition number)，该字段为2比特(bits)时会指示如下表1中的一列，从而指示具体的重复次数，表格中r1，r2，r3，r4表示不同的重复次数等级，r1为重复次数最少的等级,同样r4为重复次数最多的等级。
Figure PCTCN2020123429-appb-000002
表1
例1，RRC指示了最大重复次数为4，则对应上述表格，r1对应重复次数为1，r2对应重复次数为2，r3对应重复次数为4，示例性的，如果网络设备通过DCI来指示具体的重复次数为r1，则该PDCCH的重复发送次数为1；例2，RRC指示了最大重复次数为16，则对应上述表格，r1对应2，r2对应4，r3对应8，r4对应16，可以通过DCI指示确定的重复次数等级以确定具体的重复次数。
2、通过重复发送多次PDSCH来增强PDSCH的覆盖。通过RRC信令配置承载RAR的PDSCH的最大重复次数，并在36.213协议中定义PDSCH重复等级表格，通过DCI format 6-1A指示重复次数，具体为：
通过RRC信令pdsch-最大(max)NumRepetition控制单元(conctrol element,CE)方式A(modeA)来配置对应覆盖增强等级A的PDSCH的最大重复次数，可以配置为16或32次。
DCI format6-1A中的字段Repetition number来指示如下表2中与高级覆盖参数(Higher layer parameter)对应的具体的PDSCH重复级别，从而指示具体的重复次数：
Figure PCTCN2020123429-appb-000003
表2
例如RRC信令配置最大重复次数为16，则通过查询上述表格，得到候选的重复次数的集合为{1,4,8,16}，网络设备通过DCI指示具体的重复次数，终端设备可以结合pdsch-maxNumRepetitionCEmodeA参数以及DCI的指示来确定具体的重复次数。例如，通过DCI中的2bits可以指示{1,4,8,16}中的一种重复次数，即PDSCH的发送次数，Not configured为未配置。
对于PDCCH，由于系统信息块(system information block，SIB)是承载在PDSCH中传输，该PDSCH会由PDCCH来调度。PDCCH包括一个或多个控制信道单元(control-channel elements，CCEs)，具体是由聚合等级来确定的，例如表3所示：
Aggregation level Number of CCEs
1 1
2 2
4 4
8 8
16 16
表3
PDCCH支持不同聚合等级(aggregation level,AL)和CCE之间的关系可以用下表4来表示：
Figure PCTCN2020123429-appb-000004
表4
控制资源集(Control resource set，CORESET)是NR新引入的概念，表示用于承载PDCCH的时频资源集合。
1个UE可以配置多个CORESET，每个CORESET只能绑定1个CCE到资源元素组(resource element group，REG)映射关系。REG是PDCCH资源映射的基本单位，1个REG定义为1个OFDM符号上的1个RB。资源元素组束(REG bundle)是NR新引入的概念。REG以时间优先映射(time-first)的方式先组成REG bundle，再以REG bundle为粒度交织或非交织地映射到控制资源上。1个REG bundle(REG组合)由一组在时域和/或频域上连续的REG组成，1个REG bundle大小等于频域上占REG的大小乘以时域上占OFDM符号的大小。组成PDCCH的CCE以REG bundle为基本单位映射在CORESET(control-resource set，控制资源集)上。CORESET上的REG以先时域后频域的递增顺序编号。
L个连续的REG组成一个REG bundle。
UE在盲检测PDCCH的时候，首先获取CORESET的信息，该CORESET可以理解为资源集合，基站会在CORESET的某一个PDCCH的候选(candidate)资源发送PDCCH，而UE会通过盲检测的方式，按照一定的规则检测所有的candidates(规则包括检测每种聚合等级，对应不同的聚合等级有不同的candidate数，对不同类型的加扰进行检测)，直到成功解码该PDCCH。
终端设备可以有不同的类型，例如终端设备类型1和终端设备类型2，并且，终端设备类型1和终端设备类型2的第一特征信息是不同的。其中终端设备的第一特征信息包括以下中的至少一种：带宽(信道带宽)、支持或配置的资源单元数(资源单元可以是RB，RE，子载波，RB组，REG bundle，控制信道元素，子帧，无线帧，时隙，迷你时隙，符号)、射频通道数、混合自动重传请求(hybrid automatic repeat request，HARQ)进程数、支持的峰值速率、应用场景、时延要求、处理能力、协议版本、双工方式(半双工，全双工)、业务(物联应用如视频监控，移动宽带(mobile broadband，MBB)等)、聚合等级信息、候选控制信道信息，终端设备的类型、终端设备的发射天线数、终端设备的接收天线数、资源、资源索引、级别、级别索引、增强级别、增强级别索引、重复级别、重复级别索引、重复次数、重复次数索引、覆盖增强值、覆盖增强范围的索引、路径损耗值、路径损耗范围的索引、参考信号接收功率值、参考信号接收功率范围的索引、参考信号接收质量值、参考信号接收质量范围的索引、信道质量信息值、信道质量信息范围的索引、业务类型、业务类型的索引、功率节省需求、功率节省需求的索引、时延需求、时延需求的索引、检测预先规定的所述第一信道的次数、检测预先规定的所述第一信道的次数的索引、移动性需求、移动性需求的索引。
需要说明的是，本申请实施例的终端设备类型1，终端设备类型2可以为REDCAP的不同终端类型，也可以是终端设备类型1为REDCAP UE，终端设备类型2为常规终端设备(legacy UE)，或者其他情况，类型种类也可以多于两种，在此不做限制，本申请实施例中以终端设备类型1和终端设备类型2为REDCAP的不同终端类型为例进行说明。

基于随机接入架构和基站与UE传输架构，下面对本申请实施例中的通信方法进行描述：
本申请中，终端设备是一种具有无线收发功能的设备，可以是固定设备，移动设备、手持设备(例如手机)、穿戴设备、车载设备，或内置于上述设备中的无线装置(例如，通信模块，调制解调器，或芯片系统等)。所述终端设备用于连接人，物，机器等，可广泛用于各种场景，例如包括但不限于以下场景：蜂窝通信、设备到设备通信(device-to-device，D2D)、车到一切(vehicle to everything，V2X)、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)、物联网(internet of things，IoT)、虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、智能家具、智能办公、智能穿戴、智能交通，智慧城市(smart city)、无人机、机器人等场景的终端设备。所述终端设备有时可称为用户设备(user equipment，UE)、终端、接入站、UE站、远方站、无线通信设备、或用户装置等等，为描述方便，本申请中将终端设备以UE为例进行说明。
本申请中的网络设备，例如包括接入网设备，和/或核心网设备。所述接入网设备为具有无线收发功能的设备，用于与所述终端设备进行通信。所述接入网设备包括但不限于上述通信系统中的基站(BTS,Node B,eNodeB/eNB，或gNodeB/gNB)、收发点(transmission reception point,TRP)，3GPP后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。所述基站可以是：宏基站，微基站，微微基站，小站，中继站等。多个基站可以支持上述提及的同一种接入技术的网络，也可以支持上述提及的不同接入技术的网络。基站可以包含一个或多个共站或非共站的传输接收点。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)，和/或分布单元(distributed unit，DU)。网络设备还可以是服务器，可穿戴设备，或车载设备等。例如，V2X技术中的网络设备可以为路侧单元(road side unit，RSU)。以下对接入网设备以为基站为例进行说明。所述通信系统中的多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同接入技术中的多个基站进行通信。所述核心网设备用于实现移动管理，数据处理，会话管理，策略和计费等功能。不同接入技术的系统中实现核心网功能的设备名称可以不同，本申请并不对此进行限定。以5G系统为例，所述核心网设备包括：访问和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)、或用户面功能(user plane function，UPF)等。
需要说明的是，终端设备根据网络设备发送的消息进行处理可以通过调整因子处理，也可以不通过调整因子处理，下面分别说明：
一、终端设备不通过调整因子处理网络设备发送的消息：
本实施中，终端设备根据接入状态信息确定是否接入网络，根据第一重复次数集合确定第一信道的第一重复次数。该接入状态信息用于指示终端设备是否可以接入网络，当该接入状态信息指示终端设备不能接入网络时，终端设备停止监听PDCCH，当该接入状态信息指示终端设备可以接入网络时，终端设备执行确定第一重复次数的操作。具体的，接入状态信息可以包括至少一个比特，通过比特状态、比特值来指示终端设备是否可以接入网络，例如，比特值为1时表示终端设备可以接入网络，比特值为0时表示终端设备不可以接入网络。
实际应用中，终端设备可以确定接入状态信息，也可以不确定接入状态信息，下面分别说明：
1、需要确定接入状态信息：
本实施例中，终端设备可以根据接入状态信息确定是否可以接入网络，请参阅图4，本申请实施例中通信方法一流程包括：
401、终端设备向网络设备发送接入请求，相应的，网络设备接收来自终端设备的接入请求。
本实施例中，终端设备在接入网络的随机接入过程中，终端设备可以向网络设备发送接入请求，该请求可以包括终端设备的第一特征信息，也可以不包括第一特征信息，本实 施例对此不作限定。
402、网络设备确定接入状态信息和重复等级信息。
本实施例中，网络设备可在如下四种情况下确定接入状态信息：
情况1：网络设备根据终端设备的接入请求确定该终端设备的终端类型，该终端类型可以是通过第一特征信息确定的，具体的，第一特征信息为该终端设备的随机接入序列的时域资源和/或频域资源，具体此处不作限定。
情况2：终端设备发送接入请求后，可以通过Msg3向网络设备发送第一特征信息，具体的，第一特征信息可以为该终端设备的带宽，或者终端设备的发射天线数，终端设备的接收天线数。
情况3：终端设备发送接入请求后，并且已经接入到网络，终端设备通过物理上行共享信道发送第一特征信息，例如第一特征信息为该终端设备的带宽，或者终端设备的发射天线数，终端设备的接收天线数。
情况4：网络设备不需要根据第一特征信息确定第一信息。网络设备会根据此时的负载情况，确定是否允许终端设备接入网络。例如，当网络的负载较大，即接入网络的终端设备的数量较多，则不允许REDCAP UE或某一类型的终端设备接入网络；当网络的负载较小，即接入网络的终端设备的数量较少，则允许REDCAP UE或某一类型的终端设备接入网络。
以上情况1至4，当网络设备根据第一特征信息确定发送接入请求的终端设备为REDCAP UE时，如果网络设备不支持该终端类型，例如网络设备可能只支持legacy UE，而不支持REDCAP UE，则确定该终端设备不被允许接入网络；如果该终端设备为legacy UE或者网络设备也支持REDCAP UE，则确定该终端设备被允许接入网络。
网络设备可以指示给终端设备如何上报终端设备的设备类型(也就是下行的指示方式)包括：网络设备可以通过主信息块(master information block，MIB)、物理广播信道(physical broadcast channel,PBCH)、系统信息块(system information block，SIB)或PDCCH(用于调度承载SIB1的PDSCH的PDCCH)来指示终端设备，该系统信息块可以为SIB1，也就是说网络设备的指示信息可以承载于上述信道，可以由上述信道承载的至少一个比特来指示，例如当需要指示两种设备类型时，可以通过1个比特来指示，当需要指示三种或四种设备类型时，可以通过2个比特来指示。网络设备可以指示不同设备类型对应的随机接入序列的时域资源，和/或频域资源，和/或码域资源，则网络设备根据资源可以识别不同类型的终端设备；也可以指示终端设备通过特定的比特或字段上报设备类型；还可以指示终端设备不需要在随机接入阶段识别终端设备的设备类型，也就是说指示终端设备无需向网络设备指示所述设备类型。进一步，网络设备可以通过多个指示信息来分别指示不同类型的终端设备对应的不同上报方式，例如，对于四种不同的终端设备类型，网络设备可以通过SIB1中的4个比特来分别指示四种设备类型分别对应的四种上报方式。
相应的，终端设备指示网络设备所述设备类型的方式(也就是上行的指示方式)包括：通过Msg1传输，或Msg3传输，或消息A(MsgA)传输，或消息5(Msg5)传输，或承载UE能力信息的PUSCH传输。具体的，终端设备可以通过传输资源与设备类型的对应关系来 指示，也可以通过特定的比特或字段来指示。其中，终端设备可以根据来自网络设备的消息来确定具体的指示方式，也可以通过预定义的规则来确定具体的指示方式。例如，网络设备通过MIB来指示至少一个设备类型对应的至少一个Msg1资源，终端设备接收MIB之后可以根据MIB以及所述设备类型来确定对应的Msg1资源，根据对应的Msg1资源向网络设备发送Msg1,网络设备根据Msg1的资源确定对应的设备类型。又例如，网络设备通过PBCH指示终端设备在Msg3消息中的一个比特来上报设备类型；再例如，标准预定义终端设备在MsgA中上报设备类型。
应理解，上述的多种下行的指示方式以及多种上行的指示方式可以相互组合。
网络终端可以根据第一特征信息确定接入状态信息，即网络设备先根据第一特征信息确定该终端设备是否可以接入网络，当终端设备不可以接入网络时，网络设备可以设置一个比特状态指示该终端设备不被允许接入网络，该比特状态即为网络设备确定的接入状态信息，即比特状态与第一特征信息相关。在一个示例中，该第一特征信息可以为终端设备的设备类型，当该设备类型为终端设备类型1或终端设备类型2时，如果网络设备只支持legacy UE，而不支持REDCAP UE，则网络设备可以设置该比特状态来指示该终端设备不被允许接入网络。具体的，该比特状态可以为比特值(bit value)。可选的，还可以有其他比特状态对应其他不同第一特征信息的终端设备，用于指示其他设备类型的终端设备是否被允许接入网络。
在另一个示例中，该比特状态也可以是为0或1，如果网络设备只支持legacy UE，而不支持REDCAP UE，当设备类型为终端设备类型1或终端设备类型2时，该比特状态设置为0，即该终端设备不被允许接入网络；当设备类型为legacy UE时，该比特状态设置为1，即该终端设备被允许接入网络，本实施例对此不作限定。
当终端设备不被允许接入网络时，网络设备确定的重复等级信息指示的信息可以为空，或者步骤402不需要确定重复等级信息。
当终端设备被允许接入网络时，网络设备可以根据预定义的规则确定出第一信道对应的第一重复次数、重复等级信息和第一最大重复次数，第一信道为网络设备和终端设备传输信息的物理性通道，可以是PDCCH，还可以是其他信道，例如PDSCH、PUSCH等。
该第一重复次数可以为网络设备发送第一信道的发送次数。
重复等级信息是对终端设备接收第一信道可能的重复次数的个数的体现。
第一最大重复次数则是用于结合重复等级信息划定重复次数选择范围。
该重复等级信息可以用来指示该第一信道对应的第一重复次数集合，第一重复次数集合为终端设备接收或发送第一信道可能的重复次数的集合，第一重复次数集合包括的第一重复次数可以为一个也可以为多个。示例性的，当终端设备的设备类型为legacy UE时，重复等级信息可以设置为第一数值，该第一数值用于指示上述第一重复次数为1，或者，用于指示上述第一重复次数为第一预定义值。第一预定义值可以是第一最大重复次数R max，还可以是其他数值，例如

具体此处不作限定。第一数值可以为设置为1或其他数值，具体此处不作限定。
在一种可能的示例中，终端设备类型1的重复等级信息可以设置为第二数值，例如4， 用于指示该设备类型的终端设备对应的第一重复次数集合包含4个重复次数，示例性的，可以为R max,
Figure PCTCN2020123429-appb-000006
然后网络设备可以通过配置第一指示消息(例如DCI)来指示其中的第一重复次数；终端设备类型2的重复等级信息可以设置为第三数值，例如2，用于指示该设备类型的终端设备对应的第一重复次数集合包含2个重复次数，示例性的，可以为R max,
Figure PCTCN2020123429-appb-000007
然后网络设备可以通过配置第一指示消息(例如DCI)来指示其中的第一重复次数。
当接入状态信息指示终端设备不被允许接入网络时，本申请实施例的第一信息只包含该接入状态信息或者第一信息包括接入状态信息和重复等级信息，该重复等级信息指示的信息为空；当接入状态信息指示终端设备被允许接入网络时，第一信息包括接入状态信息、重复等级信息和第一最大重复次数。此时，第一信息也可以由多个消息承载，例如分别承载接入状态信息，重复等级信息和第一最大重复次数。
403、网络设备向终端设备发送接入状态信息和/或重复等级信息，相应的，终端设备接收来自网络设备的接入状态信息和/或重复等级。
网络设备确定了接入状态信息和重复等级信息后，网络设备将包括接入状态信息和重复等级信息的第一信息发送给终端设备。可选的，在当终端设备不被允许接入网络时，该重复等级信息为空或者网络设备只发送接入状态信息给终端设备。
404、终端设备确定是否可以接入网络，如果终端设备可以接入网络，则执行步骤406，如果终端设备不能接入网络，则执行步骤405。
终端设备可以基于接收的上述第一信息，确定接入状态信息，并根据该接入状态信息判断该终端设备是否可以接入网络。示例性的，当第一信息中的比特状态为1时，可以指示终端设备可以接入网络，比特状态为0时，可以指示终端设备不可以接入网络；或者该比特状态有数值时指示终端设备可以接入网络，该比特状态没有数值时终端设备不可以接入网络，具体此处不作限定。
405、终端设备确定无法接入网络。
终端设备确定接入状态信息后，如果该接入状态信息指示终端设备不被允许接入网络，则终端设备确定无法接入网络，停止监听网络设备通过物理信道传输的信息。
406、终端设备确定第一重复次数。
终端设备确定可以接入网络后，可以根据第一信息确定重复等级信息和第一最大重复次数，并基于该重复等级信息确定第一信道的第一重复次数，示例性的，当重复等级信息为1时，终端设备不需要盲检测PDCCH，终端设备可以确定该第一重复次数为1或者第一预定义值；当重复等级信息为2或4时，终端设备可以根据重复等级信息和第一最大重复次数确定第一重复次数集合，此时终端设备需要盲检测PDCCH获取第一指示信息(例如DCI)确定第一重复次数集合中的第一重复次数。
407、终端设备传输第一信道。
终端设备在确定第一重复次数后，可以根据该第一重复次数接收第一信道。示例性的，当第一信道为PDCCH时，网络设备根据该第一重复次数发送PDCCH，具体的，网络设备发送PDCCH的时序不做限定，终端设备根据该第一重复次数接收该PDCCH；该PDCCH可以是 调度系统信息块(system information block，SIB)的PDCCH，或者是调度承载RAR的PDSCH的PDCCH，或者是调度承载Msg4的PDSCH的PDCCH，或者是调度其他承载下行数据的PDSCH的PDCCH。当第一信道为PDSCH时，终端设备根据第一重复次数接收该PDSCH，或者其他承载下行数据的PDSCH；该PDSCH可以是承载SIB的PDSCH，或者是承载RAR的PDSCH，或者是承载Msg4的PDSCH。当第一信道为PUSCH时，步骤407执行的步骤还可以是UE根据第一重复次数发送PUSCH；该PUSCH可以是承载Msg3的PUSCH，或者其他承载上行数据的PUSCH，具体此处不作限定。
本申请实施例中，终端设备可以根据网络设备发送的接入状态信息确定是否可以接入网络，避免终端设备不被支持接入网络时仍监听第一信道浪费网络资源，能够节省网络资源、提高通信效率。
进一步的，终端设备根据重复等级信息确定第一重复次数可以减少盲检测的复杂度。
2、网络设备不需要向终端设备发送接入状态信息：
实际应用中，网络设备可以不发送接入状态信息给终端设备，该接入状态信息可以由第一信息中的其他信息指示，并指示重复次数集合，网络设备也可以不限制终端设备类型，即不同终端设备都可以接入网络，网络设备可以向终端设备发送直接包含重复次数集合的第一信息，下面分别说明：

2.2、网络设备向终端设备发送直接包含重复次数集合的第一信息：
本实施例中，网络设备直接向终端设备发送重复次数集合，具体的，重复次数集合指示的重复次数中，PDCCH的重复次数可能与PDSCH的重复次数有关联，也可能跟PUSCH的重复次数有关联。
2.2.1、PDCCH的重复次数与PDSCH的重复次数存在关联关系，终端设备可以根据PDCCH的重复次数确定PDSCH的重复次数，或根据PDSCH的重复次数确定PDCCH的重复次数，以减少PDSCH或PDCCH的指示信息所占用的网络资源：
请参阅图7，本实施例通信方法另一流程包括：
701、终端设备向网络设备发送接入请求，相应的，网络设备接收来自终端设备的接入请求。
本实施例中步骤701可以参照图4所示实施例中步骤401的相关说明，此处不再赘述。
702、网络设备确定第一重复次数集合和第二重复次数集合。
本实施例可基于如图4所示实施例中步骤402中四种情况的前提下和终端类型的指示方法实施，此处不再赘述。
在一种可能的实施方式中，第一信道的第一重复次数与终端设备的第一特征信息相关联，示例性的，第一特征信息以设备类型为例，当网络设备允许该终端设备接入网络时，如果终端设备的设备类型为legacy UE，则网络设备可以确定第一重复次数为1或者第一预定义值。如果UE的设备类型为终端设备类型1，网络设备可以确定第一重复次数为16；如果终端设备的设备类型为终端设备类型2，网络设备可以确定第一重复次数为4，以上数值仅为举例，具体此处不作限定。第二信道的第二重复次数与第一重复次数确定方式相同，此处不再赘述，但是第二重复次数与第一重复次数之间可以存在线性运算关系。
网络设备确定第一重复次数和第二重复次数后，可以通过按照预定义的规则或表格或者基于接收的多个终端设备的接入请求确定第一重复次数对应的第一重复次数集合和第二重复次数对应的第二重复次数集合。可选的，网络设备也可以是根据第一特征信息确定第一重复次数集合或第二重复次数集合。
703、网络设备向终端设备发送第一重复次数集合和第二重复次数集合，相应的，终端设备接收来自网络设备的第一重复次数集合和第二重复次数集合。
网络设备确定第一重复次数集合和第二重复次数集合后，可以通过RRC消息向终端设备发送第一重复次数集合和第二重复次数集合，当第二重复次数集合只有一个重复次数时，该重复次数为第一参数，当第二重复次数集合有多个重复次数时，终端设备可以通过网络设备发送的第一指示信息选择第二重复次数集合中的一个重复次数作为第一参数。
704、终端设备确定第一重复次数和第二重复次数。
当第一重复次数集合指示一个最大重复次数时，终端设备可以按照预定义的规则或表格确定该最大重复次数指示的多个重复次数，并且根据上述第一指示信息从上述多个重复 次数中确定第一重复次数；当第一重复次数集合指示多个重复次数时，终端设备可以直接根据该第一指示信息确定第一重复次数，然后将第一重复次数和第二重复次数集合通过线性运算算法计算出第二重复次数，具体的，当第二重复次数集合只包括一个重复次数时，则该重复次数为第一参数，可以与第一重复次数直接计算出第二重复次数；当第二重复次数集合包括多个重复次数时，终端设备可以先通过第一指示信息中的1比特数据指示出第二重复次数集合中的第一参数，然后将该第一参数与第一重复次数通过线性计算得出第二重复次数。
示例性的，当第二重复次数集合只包括一个重复次数时，第一指示信息例如DCI指示PDCCH第一重复次数X，网络设备通过RRC消息向终端设备指示PDSCH第一参数Y，则PDSCH的第二重复次数可以根据X和Y确定，该确定方式可以是相加、相乘以及其他的线性运算关系。示例：DCI中指示的PDCCH的第一重复次数为2，网络设备通过RRC消息向终端设备指示PDSCH的第一参数为4，则PDSCH的第二重复次数可以是2*4＝8次。当第二重复次数集合包括多个重复次数时，DCI中指示的PDCCH的第一重复次数为2，网络设备通过RRC消息向终端设备指示PDSCH的第二重复次数集合为{1,2,4,8}，则终端设备可以先通过DCI指示第二重复次数集合中的第一参数，然后将第一参数与第一重复次数相乘，也可以先将第二重复次数与第一重复次数相乘，并与第二重复次数集合取并集，则PDSCH的实际重复次数集合可以是{1,2,4,8,16}，然后终端设备通过DCI指示该实际重复次数集合中的一个值获得第二重复次数。具体的，第一信道可以为PDCCH，第二信道可以为PDSCH，或者，第一信道可以为PDSCH，第二信道可以为PDCCH，具体此处不作限定。
上述线性运算关系用于表示PDSCH重复次数集合或者PDSCH重复次数，与PDCCH聚合等级、网络设备支持的终端设备的设备类型、网络设备支持的终端设备的能力(如接收天线数)中的一种或多种的关系。示例：PDSCH的重复次数与网络设备支持的终端设备的设备类型相关，对于终端设备类型1的终端设备，PDSCH的重复次数较大，对于终端设备类型2的终端设备，PDSCH的重复次数较小，legacy UE则对应更小的重复次数，又或者，若PDCCH的聚合等级大，则PDCCH的解码性能较好，并且覆盖较好，此时PDSCH的重复次数可以为较小的重复次数，综上所述，可以适应性地对线性运算算法进行调节。
705、网络设备向终端设备发送第一信道和第二信道，相应的，终端设备接收来自网络设备的第一信道和第二信道。
本实施例中，终端设备根据确定的上述第一重复次数接收PDCCH和根据上述第二重复次数接收PDSCH，或根据第一重复次数接收PDSCH和根据第二重复次数接收PDCCH。
本实施例中，网络设备指示终端设备第一信道和第二信道的重复次数通过DCI只需指示其中一个信道的重复次数或者指示第二个重复次数所需的比特数据更少，能够节省网络资源、提高通信效率。
2.2.2、PDCCH的重复次数与PUSCH的重复次数有关联
终端设备可以基于PDCCH的重复次数可能与PUSCH的重复次数的关联关系，根据PDCCH的重复次数确定PUSCH的重复次数，或根据PUSCH的重复次数确定PDCCH的重复次数，减少PUSCH或PDCCH的指示信息所占用的网络资源：

804、终端设备确定第一重复次数和第二重复次数。
第一重复次数和第二重复次数的确定可参照图7所示实施例中步骤704的确定方式，此处不再赘述。
示例性的，第一信道可以为PDCCH，第二信道可以为PUSCH，或者，第一信道可以为PUSCH，第二信道可以为PDCCH，具体此处不作限定。
805、终端设备传输第一信道和第二信道。
本实施例中，第一信道为PDCCH，第二信道为PUSCH时，终端设备可以根据第一重复次数接收PDCCH，根据第二重复次数发送PUSCH。
在另一示例中，当第一信道为PUSCH，第二信道为PDCCH时，终端设备还可以是根据第一重复次数发送PUSCH，根据第二重复次数接收PDCCH，具体此处不作限定。
本实施例中，网络设备指示终端设备第一信道和第二信道的重复次数通过DCI只需指示其中一个信道的重复次数或者指示第二个重复次数所需的比特数据更少，能够节省网络资源、提高通信效率。
二、终端设备通过调整因子处理来自网络设备的第一最大重复次数或第一重复次数集合，以确定实际的接收第一信道的第一重复次数，节省基站获取该终端设备的设备类型所占用的计算资源：
请参阅图9，本实施例中通信方法的另一流程包括：
901、终端设备向网络设备发送接入请求，相应的，网络设备接收来自终端设备的接入请求。
本实施例中步骤901可以参照图4所示实施例中步骤401的相关说明，具体此处不再赘述。
902、网络设备确定第一最大重复次数或第一重复次数集合。
本实施例可参照如图4所示实施例中步骤402中四种情况的前提下和终端类型的指示方法实施，此处不再赘述。
本实施例中，当网络设备确定该终端设备被允许接入网络时，第一信道的第一重复次数与该设备类型相关联，第一信道可以为PDCCH，还可以是其他信道，例如PDSCH、PUSCH，具体此处不作限定。示例性的，当终端设备的设备类型为legacy UE时，第一重复次数可以为1或者第一预定义值。当终端设备的设备类型为终端设备类型1时，第一重复次数可以为16；当终端设备的设备类型为终端设备类型2时，第一重复次数可以为4，以上数值 仅为举例，具体此处不作限定。
网络设备确定第一重复次数后，基于该第一重复次数可以确定该终端设备对应的第二最大重复次数或者第二重复次数集合。可选的，网络设备也可以是根据第二特征信息确定第一最大重复次数或第一重复次数结合。
903、网络设备向终端设备发送第一重复次数或第一重复次数集合，相应的，终端设备接收来自网络设备的第一最大重复次数或第一重复次数集合。
第一最大重复次数或第二重复次数集合可以是通过高层信令或物理层信令配置的，例如RRC信令，或MAC CE，或者是物理层信令，如DCI。
904、终端设备根据调整因子确定第一重复次数。
终端设备在接收到上述第一最大重复次数或第一重复次数集合后，可以在上述第一最大重复次数或第一重复次数集合中根据调整因子确定第一重复次数。在一个示例中，终端设备接收来自网络设备的第一最大重复次数后，可以根据调整因子对第一最大重复次数进行调整，获得终端设备实际对应的第二最大重复次数，终端设备将该第二最大重复次数按照预定义的规则或表格得到多个可能的重复次数，再根据来自网络设备的第一指示信息从多个可能的重复次数中确定第一重复次数。该第一指示信息可以是物理层信令或者是高层信令，物理层可以是DCI，高层信令可以是RRC或MAC CE。网络设备可以通过高层信令向终端设备预配置调整因子，也可以是在与终端设备之间的协议中预定义该调整因子，也可以是通过物理层信令向终端设备指示调整因子，还可以是通过第一特征信息使得终端设备确定该调整因子。
在另一个示例中，终端设备接收网络设备发送的第一重复次数集合后，可以根据调整因子对该第一重复次数集合进行调整，获得该终端设备实际对应的第二重复次数集合，终端设备可以根据网络设备发送的第一指示信息从该第二重复次数集合中确定上述第一重复次数。
示例性的，以网络设备发送的RRC消息中包含的legacy UE的第一最大重复次数或第一重复次数集合为例，终端设备类型1的调整因子可以配置为4，终端设备类型2的调整因子可以配置为2，legacy UE的调整因子则为1或者不设置，终端设备可以将各终端类型的调整因子可以作用于legacy UE的第一最大重复次数上，例如第一最大重复次数为8，则终端设备类型1的最大重复次数为32，终端设备类型2的最大重复次数为16，legacy UE的最大重复次数为8。终端设备获得最大重复次数后，可以通过查表得到重复次数集合，然后根据第一指示信息例如DCI指示第一重复次数。调整因子也可以作用于第一重复次数集合，legacy UE的重复次数集合为{1,2,4,8}，终端设备类型2的重复次数集合为{2,4,8,16}，终端设备类型1的重复次数集合为{4,8,16,32}。在本示例中，终端设备类型1或终端设备类型2的调整因子也可以是1，不指示或不配置则调整因子默认为1。
上述调整因子为网络设备通过高层信令或物理层信令向终端设备配置的，高层信令可以包括RRC消息或MAC CE，物理层信令为第一指示信息例如DCI；或者上述调整因子为所述网络设备预定义的；或者上述调整因子与第一特征信息相关。示例性的，调整因子可以是通过DCI来指示的，例如DCI中的1或2比特指示调整因子集合中调整因子的值，该调 整因子集合可以RRC信令配置的，或者调整因子是legacy UE的重复次数集合中的一个数值，或者是终端设备类型1的重复次数集合中的一个数值，或者是终端设备类型2的重复次数集合中的一个数值。示例性的，调整因子可以是通过RRC来指示的，例如RRC信令配置调整因子集合中的一个值，该调整因子集合可以是预定义的，或者RRC信令配置legacy UE的重复次数集合中的一个数值为调整因子，或者RRC信令配置终端设备类型1的重复次数集合中的一个数值为调整因子，或者RRC信令配置终端设备类型2的重复次数集合中的一个数值为调整因子。示例性的，调整因子是根据第一特征信息确定的，终端设备类型1与终端设备类型2的第一特征信息不同，则定义不同的调整因子，例如接收天线数为1根天线的终端设备的调整因子大于接收天线数为2根天线的终端设备的调整因子，接收能力强的终端设备的调整因子小于接收能力弱的终端设备的调整因子，即接收能力强的终端设备的重复次数小于接收能力弱的终端设备的重复次数。
905、终端设备传输第一信道。
本实施例中步骤905可以参照图4所示实施例中步骤407的相关说明，此处不再赘述。
