Description

一种无线接入的方法以及装置
本申请要求于2020年8月7日提交中国专利局、申请号为202010791129.4、申请名称为“一种无线接入的方法以及装置”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
本申请涉及通信领域，并且，更具体地，涉及无线接入的方法和装置。
背景技术
在通信过程中，由于机器类终端设备所对应的应用场景下的业务对数据传输速率要求并不高，可以降低实现规格，进而降低实现成本；另一方面，降低机器类终端设备的实现成本也有助于扩大机器类终端设备的市场，促进物联市场的发展。
然而，在一些场景下，如新无线(new radio，NR)系统，在初始接入阶段中，基站与对应的小区之间没有交互，因此基站无法获取终端设备的类型，例如机器类终端设备，进而无法确定终端设备的带宽能力；同时，由于基站还无法识别每个机器类终端设备，因此，无法通过终端设备的专有信令为每个机器类终端设备单独配置数据传输频率资源，进而会导致非连接态的数据传输频率资源上的负载过重；此外，上行初始带宽部分可以用于随机接入过程中用于传输信息3的物理上行共享信道和用于传输混合自动重传请求反馈的物理上行控制信道，其中混合自动重传请求反馈为初始接入过程中对于信息4的反馈，此外，初始接入过程中的物理随机接入信道资源也都必须在上行初始带宽部分内传输。进一步的，终端设备还可以通过物理上行控制信道跳频、物理上行共享信道跳频保证在连接过程中与基站之间的数据传输性能，其中物理上行控制信道跳频的频率范围以及物理上行共享信道跳频的频率范围也需要保证在上行初始带宽部分内。因此定义包括上述数据传输资源以及跳频资源的频率范围对于NR终端设备而言是有必要的，这样才能保证与基站建立数据传输连接。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
第五代(the Fifth-Generation，5G)移动通信技术新无线(New Radio，NR)，是基于正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)的全新空口设计的全球性5G标准，也是下一代非常重要的蜂窝移动技术基础，5G技术的业务非常多样，可以面向增强型移动宽带(Enhanced Mobile Broadband，eMBB)业务、超可靠低延时通信(Ultra-Reliability Low-Latency Communication，URLLC)业务以及大规模机器通信(Massive Machine-Type Communication，mMTC)业务，其中mMTC业务例如可以是工业无线传感器网络(Industrial Wireless Sensor Network，IWSN)业务，视频监控(Video Surveillance)业务，以及可穿戴(Wearables)业务。
机器类终端设备，往往对成本、功率消耗有更高的要求。例如机器类终端设备一般是低成本实现的，这是因为机器类终端设备所对应的应用场景下的业务对数据传输速率要求并不高，比如IWSN下的传感器所承载的数据传输速率不大于2Mbps就足以满足IWSN业务，经济型视频监控摄像头所承载的数据传输速率一般为2～4Mbps，可穿戴业务下的终端设备例如智能手表下行峰值速率不超过150Mbps，其上行峰值速率不超过50Mbps，远低于NR legacy终端设备(例如NR eMBB终端设备)的峰值速率，基于此，机器类终端设备可以相对于NR legacy终端设备降低实现规格，进而降低实现成本；另一方面，降低机器类终端设备的实现成本也有助于扩大机器类终端设备的市场，促进物联市场的发展。 目前，3GPP启动了在NR系统下对低能力终端设备(NR reduced capability，NR RedCap)的研究(reference：RP-193238)，旨在针对日益增长的物联市场，例如上述提到的IWSN、视频监控以及可穿戴业务，设计一种满足物联市场性能需求且成本低/实现复杂度低的终端设备，以扩大NR系统在物联市场的应用。为了便于描述，在本文的后续部分，都以NR RedCap UE为例进行说明。
降低终端设备成本的一种实现方式是降低终端设备的信道带宽，或者也可以理解为降低终端设备的带宽能力，即NR RedCap UE的带宽能力可以远小于NR legacy终端设备的带宽能力。目前NR Legacy终端设备例如版本Rel-15/版本Rel-16的终端设备必须要具备的带宽能力为100MHz，而NR RedCap UE从可以接收NR基站发送的初始接入信号进而接入NR系统角度而言，其带宽能力可以只有20MHz，在某些NR系统的配置下，NR RedCap UE的带宽能力可以进一步降低，例如为5MHz或者10MHz，此时，NR RedCap UE也可以接入NR系统。不大于20MHz的带宽能力相对于100MHz的带宽能力，可以极大降低RedCap UE的成本。
本申请实施例的技术方案可以应用于各种通信系统，例如：第五代(5th generation，5G)系统或新无线(new radio，NR)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)等。本申请实施例的技术方案还可以应用于设备到设备(device to device，D2D)通信等。
为便于理解本申请实施例，首先结合图1和图2详细说明适用于本申请实施例的通信系统。
图1是适用于本申请实施例的无线通信系统100的一示意图。如图所示，该无线通信系统100可以包括至少一个网络设备，例如图1所示的网络设备111，该无线通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备121至终端设备123。网络设备和终端设备均可配置多个天线，网络设备与终端设备可使用多天线技术通信。
其中，网络设备和终端设备通信时，网络设备可以管理一个或多个小区，每个小区可以为至少一个终端设备提供服务。在一种可能的实现方式中，网络设备111和终端设备121至终端设备123组成一个单小区通信系统，不失一般性，将小区记为小区#1。网络设备111可以是小区#1中的网络设备，或者说，网络设备111可以为小区#1中的终端设备(例如终端设备121)服务。
需要说明的是，小区可以理解为网络设备的无线信号覆盖范围内的区域。
图2是适用于本申请实施例的无线通信系统200的另一示意图。如图所示，本申请实施例的技术方案还可以应用于D2D通信。该无线通信系统200包括多个终端设备，例如图2中的终端设备201至终端设备203。终端设备201至终端设备203之间可以直接进行通信。例如，终端设备201和终端设备202可以单独或同时发送数据给终端设备203。
应理解，上述图1和图2仅是示例性说明，本申请并未限定于此。例如，本申请实施例还可以应用于随机接入场景(如5G NR随机接入过程)。
还应理解，该无线通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller， BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
还应理解，该无线通信系统中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1.物理上行控制信道
物理上行控制信道(Physical Uplink Control CHannel，PUCCH)用于承载上行控制信息，相比LTE，NR PUCCH支持5种不同的格式，按照时域上所占用的符号数量可以分为短格式和长格式两种，短格式占用1-2个符号，可以承载1-2比特(bit)信息，长格式占用4-14个符号，可承载大于2bit的信息。NR引入短格式PUCCH的目的是可以缩短混合自动重传请求应答(Hybrid Automatic Repeat-Request Acknowledgement,HARQ-ACK)反馈的时延，长格式仍然是考虑到持续时间长可以保证覆盖。
NR中，考虑到系统配置的灵活性，所有大于等于2个符号的PUCCH都是可以配置跳频，包括时隙内和时隙间跳频。跳频时第一跳(hop)内的符号数量是，剩下的符号在第二hop内。
PUCCH格式0 1 3 4使用的都是低峰值平均功率比(low-PAPR)序列，可降低上行传输的峰均比。low-PAPR序列在一个基本序列的基础上通过循环移位产生，基本序列根据序列长度的不同分为了两种情况。
2.物理上行共享信道
物理上行共享信道(PUSCH，Physical Uplink Shared Channel)用于承载来自传输信道USCH的数据。所谓共享指的是同一物理信道可由多个用户分时使用，或者说信道具有较短的持续时间。
3.控制资源集合
控制资源集合(Control-Resource Set,CORESET)主要指示物理下行控制信道占用符号数(时域)、RB数(频域)，即CORESET指示包括PDCCH的频域资源。CORESET包含若干个PRB，最小为6个时域上，符号数为1-3每个小区可以配置多个CORESET(0～11)，其中COREST0可用于剩余最小系统信息(Remaining Minimum System Information,RMSI)(又可以成为系统信息块类型1(System Information Block Type 1,SIB1)的调度。
4.物理下行控制信道
物理下行控制信道(Physical Downlink Control Channel,PDCCH)承载调度以及其他控制信息，具体包含传输格式、资源分配、上行调度许可、功率控制以及上行重传信息等。PDCCH信道是一组物理资源粒子的集合，其承载上下行控制信息，根据其作用域不同，PDCCH承载信息区分公共控制信息(公共搜索空间)和专用控制信息(专用搜寻空间)。
5.主信息块
主信息块(Master Information Block,MIB),当网络侧设备开机后，会先发送MIB消息，然后再发送一系列的系统消息块(system information block,SIB)消息。MIB消息中承载的是最基本的信息，这些信息涉及到物理下行共享信道信道的解码，UE只有先解码到MIB，才能利用MIB中的参数去继续解码物理下行共享信道中的数据，包括解码系统消息块信息。
6.无线资源控制状态
RRC状态，终端设备有3种RRC状态：RRC连接态、RRC空闲态和RRC非激活态。
RRC连接(connected)态(或，也可以简称为连接态。在本文中，“连接态”和“RRC连接态”，是同一概念，两种称呼可以互换)：终端设备与网络建立了RRC连接，可以进行数据传输。
RRC空闲(idle)态(或，也可以简称为空闲态。在本文中，“空闲态”和“RRC空闲态”，是同一概念，两种称呼可以互换)：终端设备没有与网络建立RRC连接，基站没有存储该终端设备的上下文。如果终端设备需要从RRC空闲态进入RRC连接态，则需要发起RRC连接建立过程。
RRC非激活态(或，也可以简称为非激活态。在本文中，“去活动态”、“去激活态”、“非激活态”、“RRC非激活态”或“RRC去激活态”等，是同一概念，这几种称呼可以互换)：终端设备之前在锚点基站进入了RRC连接态，然后锚点基站释放了该RRC连接，但是锚点基站保存了该终端设备的上下文。如果该终端设备需要从RRC非激活态再次进入RRC连接态，则需要在当前驻留的基站发起RRC连接恢复过程(或者称为RRC连接重建立过 程)。因为终端设备可能处于移动状态，因此终端设备当前驻留的基站与终端设备的锚点基站可能是同一基站，也可能是不同的基站。RRC恢复过程相对于RRC建立过程来说，时延更短，信令开销更小。但是基站需要保存终端设备的上下文，会占用基站的存储开销。
7.系统消息块
系统消息块(System Information Block,SIB)是基站广播的系统信息，分为多种类型，这样可以用不同的频率来发送。总共有19种类型的SIB，SIB的调度信息通过MIB或SB承载。
终端设备为了保证与NR基站之间的数据传输，需要通过随机接入过程与NR基站建立起连接，以便于NR基站可以识别该终端设备，并完成后续的数据传输。以初始接入为例，NR Legacy终端设备在空闲态(idle state)，通过接收NR基站发送的同步信号块(synchronization signal block，SSB)，可以实现与NR基站之间的时频同步以及获取该NR基站对应的小区初始接入配置信息，即系统信息块1(system information block 1，SIB1)信息，在SIB1内会配置终端设备用于发起随机接入的资源，以及包括该随机接入资源的连续带宽资源，目前协议中将这一段连续带宽资源定义为上行初始带宽部分(bandwidth part，BWP)。上行初始BWP可以用于随机接入过程中用于传输信息3(message 3，Msg3)的物理上行共享信道(physical uplink shared channel，PUSCH)、随机接入过程中用于传输信息A(message A，Msg A)和用于传输混合自动重传请求(hybrid automatic repeat request，HARQ)反馈的物理上行控制信道(physical uplink control channel，PUCCH)，其中HARQ反馈为随机接入过程中对于信息4(message 4，Msg 4)或者为随机接入过程中对于信息B(message B，Msg B)的反馈，此外，随机接入过程中的物理随机接入信道(physical random access channel，PRACH)资源也都必须在上行初始BWP内传输。进一步的，终端设备还可以通过PUCCH跳频、PUSCH跳频保证在随机接入过程中以及RRC连接过程中与基站之间的数据传输性能，其中PUCCH跳频的频率范围以及PUSCH跳频的频率范围也需要保证在上行初始BWP内。因此定义包括上述数据传输资源以及跳频资源的频率范围对于NR终端设备而言是有必要的，这样才能保证与基站建立数据传输连接。
应理解，此处的上行初始BWP的形式不仅可以为保证随机接入数据传输的频率资源集合，也可以用于其他场景下的数据传输。
此外，即使终端设备进入连接态，也会在一些条件下，基于初始接入阶段对应的上行初始BWP完成数据传输。
结合上述描述，对于NR RedCap UE，为了保证与基站之间的数据传输，也需要考虑针对RedCap UE设计其上行初始BWP。
图3为一种随机接入阶段系统数据传输的一种架构图。现有技术中，首先，在随机接入阶段，上行初始BWP的频率资源配置包括在SIB1信息中，终端设备在接收SIB1信息之前，与基站之间的数据传输如图3所示，可以观察到，终端设备在接收SIB1信息之前，没有发送上行信息，即与NR基站对应的小区之间是没有交互的，因此NR基站(或网络侧设备)无法获取终端设备的类型，即不确定接收SIB1信息的终端设备是带宽能力为100MHz的终端设备还是带宽能力不大于20MHz的终端设备(例如NR RedCap终端设备)。这样就会导致现有技术存在如下问题：
(1)网络设备配置的上行初始BWP带宽超过NR RedCap UE的带宽能力，导致NR  RedCap终端设备无法接入。
例如，上行初始BWP内包括PRACH资源，根据目前协议规定，网络设备配置的总PRACH资源带宽会超过20MHz。另一方面，在NR系统中，SSB与PRACH资源(比如前导preamble)之间存在对应关系，UE根据检测到的SSB，以及SSB与preamble之间的对应关系，可以选择对应的preamble发起随机接入，网络设备通过接收到的preamble可以确定发起该preamble的UE检测到的SSB波束方向，在与该UE建立无线资源控制(radio resource control，RRC)连接之前，通过该preamble对应的SSB波束方向，向该UE发送下行数据，这样可以保证下行数据传输性能。但是由于网络设备配置的总PRACH资源带宽会超过20MHz，因此会导致NR RedCap UE无法选择最佳SSB波束方向对应的PRACH资源，进而影响RedCap UE数据传输性能，甚至导致RedCap UE无法接入。
(2)限制NR Legacy UE对应的上行初始BWP带宽，影响NR Legacy UE的初始接入性能。
网络设备考虑到系统中可能存在的NR RedCap UE，在配置上行初始BWP带宽时，可以将上行初始BWP带宽大小配置为不大于NR RedCap UE带宽能力的值，这样就可以保证RedCap UE的接入，但是这样会限制Legacy UE接入的性能，例如，如上所述，UE根据上行初始BWP的大小，可以确定上行传输信道的跳频资源范围，限制上行初始BWP的带宽，会降低上行传输信道的跳频资源范围，影响数据传输性能。又例如，根据NR RedCap UE配置上行初始BWP带宽，还会影响legacy UE接入的容量。例如针对NR Legacy UE，上行初始BWP可以最大配置到100MHz，而如果考虑NR RedCap UE与NR Legacy UE共享上行初始BWP，则上行初始BWP的带宽只能配置到20MHz，上行初始BWP的带宽缩减会降低NR Legacy UE接入的容量。
图4为一种数据传输频率资源的资源负载的一种示意图。其中，第一类型终端设备可以为低成本、低带宽的终端设备，例如NR RedCap UE，第二类型终端设备可以为传统终端设备(NR Legacy UE，例如NR eMBB UE)。如图所示，由于受限于第一类型终端设备的带宽能力，用于非连接态的数据传输频率资源一种方式下不能超过第一类型终端设备的带宽能力，这样就使得在非连接态例如初始接入阶段，网络设备与第一类型终端设备之间的数据传输只能集中在第一类型终端设备带宽能力对应的频率范围内。考虑到，在非连接态例如初始接入阶段，网络设备还无法识别每个第一类型终端设备，因此无法通过终端设备的专有信令为每个第一类型终端设备单独配置数据传输频率资源，进而会导致在非连接态下旨在与网络设备建立RRC连接的第一类型终端设备都会集中在一个频率范围内，例如20MHz。考虑到在非连接态下，该20MHz内会包括如下信道的传输：preamble传输、随机接入过程中Msg3传输、针对Msg4的HARQ-ACK传输等，以及对于连接态的终端设备，在某些条件下也会回退到非连接态下对应的数据传输频率资源上完成与网络设备的数据传输。这样就会导致非连接态的数据传输频率资源上的负载过重，特别是当考虑到第一类型终端设备连接数比较多的时候，会导致数据传输频率资源上的负载会进一步加重。针对第二类型终端设备，不存在上述问题，这是因为第二类型终端设备的必选带宽能力为100MHz，这样网络设备就可以配置频率资源范围比较大的数据传输频率资源。
第一终端设备与第二终端设备之间的区别包括如下至少一项：
1、带宽能力不同。例如第二类型终端设备最大可以支持在一个载波上同时使用 100MHz频域资源和网络设备进行数据传输，而第一类型终端设备最大可以支持在一个载波上同时使用20MHz、10MHz或者5MHz频域资源和网络设备进行数据传输。
2、收发天线个数不同。例如第二类型终端设备最小支持的天线配置为4发2收，即在最小天线配置下，使用4根接收天线接收下行数据，使用2根发送天线发送上行数据；而第一类型终端设备最大支持的天线配置低于4发2收，例如第一类型终端设备UE只支持2收1发，或者也可以支持1收1发，或者也可以支持2收2发。
3、上行最大发射功率不同。例如，第二类型终端设备的上行最大发射功率可以为23dBm或者26dBm，而第一类型终端设备的上行最大发射功率可以为4dBm～20dBm中的一个值。
4、第一类型终端设备与第二类型终端设备对应的协议版本不同。例如，NR Rel-15、NR Rel-16终端设备可以认为是第二类型终端设备，而第一类型终端设备可以认为是NR Rel-17终端设备。
5、第一类型终端设备与第二类型终端设备支持的载波聚合(carrier aggregation，CA)能力不同。例如，第二类型终端设备可以支持载波聚合，而第一类型终端设备不支持载波聚合；又例如，第一类型终端设备与第二类型终端设备都支持载波聚合，但是第二类型终端设备同时支持的载波聚合的最大个数大于第一类型终端设备同时支持的载波聚合的最大个数。例如，第二类型终端设备可以最多同时支持5个载波或者32个载波的聚合，而第一类型终端设备最多同时支持2个载波的聚合。
6、第二类型终端设备支持频分双工(Frequency Division Duplexing，FDD)，而第一类型终端设备支持半双工FDD。第一类型终端设备和第二类型终端设备对数据的处理时间能力不同。例如，第二类型终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延，小于第一类型终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延。第二类型终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延，小于第一类型终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延。
7、第二类型终端设备与第一类型终端设备的处理能力不同。第一类型终端设备的处理能力低于第二类型终端设备。例如，第一类型终端设备和第二类型终端设备对数据的处理时间能力不同。例如，第二类型终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延，小于第一类型终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延。第二类型终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延，小于第一类型终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延。又例如，第一类型终端设备能够处理的最大传输块大小(transmission block size，TBS)小于第二类型终端设备处理能够处理的TBS。又例如，第一类型终端设备能够处理的最大下行调制阶数(例如64QAM)小于第二类型终端设备能够处理的最大下行调制阶数(例如256QAM)，和/或第一类型终端设备能够处理的最大上行调制阶数(例如64QAM或者16QAM)小于第二类型终端设备能够处理的最大上行调制阶数(例如256QAM或者64QAM)。又例如，第一类型终端设备支持的混合自动重传请求(hybrid Automatic Repeat reQuest，HARQ)个数小于第二类型终端设备支持的HARQ个数。
8、第二类型终端设备的上行(或下行)传输峰值的传输速率与第一类型终端设备对应的上行(或下行)传输峰值速率不同。第一类型终端设备对应的上行(或下行)传输 峰值速率低于第二类型终端设备的上行(或下行)传输峰值的传输速率。
在本申请实施例中，第一类型终端设备以NR RedCap终端设备为例，第二类型终端设备以NR Legacy终端设备为例。
图5示出了一种适用于本申请实施例的无线接入的一种系统架构图。如图所示，本申请的网络设备与终端设备由空中接口实现连接。

对终端设备的说明：本申请中，终端设备还可以包括中继Relay，和网络设备可以进行数据通信的都可以看为终端设备。
在本申请中，小区可以理解为载波。
需要说明的是，在本申请中，虽然以低能力或低成本或低复杂度终端设备为例进行描述，但所列举的实施方式也同样适用于其他类型的终端设备，例如NR Rel-17或及以后的终端设备。为便于描述，本申请以NR RedCap UE为例进行描述。
需要说明的是，在本申请中，数据传输频率资源、或者用于PUSCH传输的最大频率资源、用于PUCCH传输的最大频率资源，以及用于NR RedCap UE preamble传输的最大频率资源都是由连续的资源块(resource block，RB)组成的。
下面将结合附图详细说明本申请提供的各个实施例。
图6为适用于本申请实施例的无线接入的方法的一种示意性流程图。方法600可以包括如下步骤。
下文实施例，为区分且不失一般性，用第一设备表示网络设备，第二设备表示第一类型终端设备，例如NR RedCap UE。
应理解，第一设备还可能有其他形式，例如，第一设备与第二设备均可以为第一类型终端设备，或者，第一设备还可以为第二类型终端设备(NR Legacy UE，例如NR eMBB UE)，第二设备可以为第一类型终端设备。此处不做限定。
应理解，在本申请中，第一类型终端设备和第二类型终端设备的主要区别在于带宽能力不同，然而在具体实施过程中，第一类型终端设备和第二类型终端设备的区别不限于带宽能力不同，即，带宽能力不同并不是必选的区别特征。
S601第一设备确定第一频率资源。
示例地，所述第一设备可以确定第一频率资源，其中，第一频率资源包括用于传输物理上行控制信道PUCCH的频率资源，第一频率资源为M个用于传输PUCCH的频率资源中的一个频率资源，这M个用于传输PUCCH的频率资源为N个第二频率资源中的M个频率资源，第二频率资源用于传输所述第一类型终端设备的上行数据，其中，M小于N，M和N均为正整数。
应理解，在本申请实施例中，所述第二频率资源可以用于传输所述第一类型终端设备的随机接入上行数据，也可以用于第二类型终端设备的随机接入上行数据。
应理解，在本申请实施例中，所述第一设备确定所述第一频率资源时，虽然所述第一频率资源为M个用于传输PUCCH的频率资源中的一个频率资源，所述M个用于传输PUCCH的频率资源为N个第二频率资源中的M个频率资源，但是，所述第一设备可以直接确定用于传输PUCCH的频率资源，无需确定所述第二频率资源。
需要说明的是，第二频率资源用于传输上行数据，优选地，这里的上行数据可以包括随机接入过程中的上行数据，例如随机接入前导序列preamble，Msg A，Msg 3，以及针对随机接入Msg 2或者Msg 4的HARQ-ACK传输，其中HARQ-ACK传输承载于PUCCH中。在一种可能的实现方式中，第二频率资源也可以用于第一类型终端设备在RRC连接态传输的上行数据。
以随机接入为例，定义N个第二频率资源用于第一类型终端设备的上行数据传输，可以实现业务负载均衡，尤其对于大连接第一类型终端设备有好处。
此外，在N个第二频率资源中定义M个第二频率资源包括PUCCH传输(其中M小于N)，可以降低PUCCH传输特别是PUCCH跳频传输对系统内其他终端设备PUSCH传输的性能影响，例如，对系统内legacy UE或者宽带UE(例如信道带宽能力为100MHz)的PUSCH传输性能影响；另一方面，考虑到PUCCH可以支持多用户复用传输，因此不需要每个第二频率资源内都包括PUCCH传输，这样在保证多用户HARQ-ACK传输性能的情况下还可以降低PUCCH的开销。
在一种可能的实现方式中，N个第二频率资源中只有1个频率资源包括用于PUCCH传输的频率资源，可以进一步降低PUCCH的传输开销。进一步在一种可能的实现方式中，当N个第二频率资源中只有1个频率资源包括用于PUCCH传输的频率资源时，第一频率资源为N个第二频率资源中包括频率最高或者频率最低的频率资源。以N＝3为例，假设3个第二频率资源中的1个第二频率资源包括的频率资源范围对应由公共资源块(common resource block，CRB)索引为p1的CRB和CRB索引为p2的CRB组成的频率资源范围，另外1个第二频率资源包括的频率资源范围对应由CRB索引为p3的CRB和CRB索引为p4的CRB组成的频率资源范围，还有1个第二频率资源包括的频率资源范围对应由CRB索引为p5的CRB和CRB索引为p6的CRB组成的频率资源范围，其中p1<p2<p3<p4<p5<p6，则包括用于PUCCH传输的频率资源或者第一频率资源可以对应频率起点为CRB索引为p1且频率终点为CRB索引p2的频率资源，或者，包括用于PUCCH传输的频率资源或者第一频率资源也可以对应频率起点为CRB索引为p5且频率终点为CRB索引p6的频率资源。这里，CRB是相对于系统载波point A确定的资源块，系统载波point A可以对应该系统载波中包括的频率最低的资源块中包括的频率最低的子载波，或者对应该系统载波带宽内包括的频率最低的频域资源单元，其中频率最低的频域资源单元包括该系统载波带宽内对应的频率最低的子载波。或者在本申请中，频率最高或者频率最低也可以用第二频率资源包括的子载波对应的频率来表示，在N个第二频率资源中，包括最低频率子载波的第二频率资源可以理解为N个第二频率资源中包括频率最低的频率资源，包括最高频率子载波的第二频率资源可以理解为N个第二频率资源中包括频率最高的频率资源。或者，在本申请中，频率最高或者频率最低也可以用N个第二频率资源包括的频率资源对应的绝对频率来确定频率最高或者频率最低。或者也可以采用其他方式，不做具体限定。由于为了保证PUCCH传输的性能，PUCCH一般采用跳频的方式，因此将包括PUCCH传输的第一 频率资源限定为N个第二频率资源中频率最高或者频率最低的频率资源，可以降低对其他终端设备PUSCH传输性能的影响，其他终端设备例如是第二类型终端设备，具有大带宽能力的终端设备(例如100MHz)，Legacy终端设备等。
在一种可能的实现方式中，第一频率资源具有如下特征：第一频率资源为一个特定频率资源内包括的频率最高或者频率最低的资源作为第一频率资源，例如第一频率资源为特定频率资源内的一段连续的频率资源，且包括该特定频率资源中频率最高的频域资源单元或者频率最低的频域资源单元。其中的特定频率资源可以为第一类型终端设备对应的系统上行载波或者第二类型终端设备对应的系统上行载波，第一类型终端设备对应的系统上行载波或者第二类型终端设备对应的系统上行载波可以相同，也可以不相同。或者，特定频率资源还可以为第二类型终端设备对应的上行初始BWP，或者，特定频率资源还可以为第一类型终端设备对应的上行信道传输带宽或者第二类型终端设备对应的上行信道传输带宽。由于为了保证PUCCH传输的性能，PUCCH一般采用跳频的方式，因此将包括PUCCH传输的第一频率资源配置在特定频率资源的频率资源的一侧，可以减轻对系统内其他终端设备例如第二类型终端设备的数据传输速率的影响。
应理解，此处的第二频率资源不仅可以为保证随机接入数据的频率资源，也可以为传输其他上行数据的频率资源，在TDD系统内，第二频率资源还可以用于传输下行数据。
第一设备可以通过广播信息通知的方式或RRC专有信令的方式，告知第二设备该第一频率资源，在此本申请不做限定。或者，第一设备还可以通过物理层信令，指示第一频率资源。
S602所述第一设备发送第一指示信息给第二设备。
示例地，第一设备发送第一指示信息，该第一指示信息用于指示第一频率资源的配置信息和/或用于传输PUCCH的资源索引的信息。
具体地，一种实现方式是，第一设备在配置N个第二频率资源时，将包括传输PUCCH的第一频率资源通过第二频率资源标识的方式实现。例如第一设备通过广播信息的方式通知N个第二频率资源，但是只有1个是包括用于传输PUCCH的频率资源，第一设备在配置N个第二频率资源时，可以同时配置第二频率资源对应的识别信息，用于指示该第二频率资源是否包括PUCCH资源。一种实现方式时，第一设备可以通过配置包括PUCCH资源的第二频率资源索引，来指示哪个第二频率资源包括PUCCH资源。例如第一设备配置了4个第二频率资源，分别对应的第二频率资源索引为0,1,2,3，则在这种实现方式下，第一设备配置包括PUCCH资源的第二频率资源索引为第二频率资源索引0-3中的任一个；或者第一设备可以直接通过配置N个第二频率资源中是否包括PUCCH资源，来实现指示包括PUCCH资源的第二频率资源。例如第一设备配置了4个第二频率资源，频率资源索引分别为0-3，同时第一设备只针对频率资源索引为0的第二频率资源配置了PUCCH资源，针对其他第二频率资源，没有配置PUCCH资源。通过对在资源配置中包括用于传输PUCCH的频率资源的识别，能够确定第一频率资源。
在一种可能的实现方式中，第一设备可以通过广播信息通知的方式将第一频率资源的配置信息和/或用于传输PUCCH的资源索引的信息告知第二设备。
在本申请实施例中，第一频率资源的配置信息包括以下至少一项：第一频率资源的频率资源位置(包括带宽大小、频率起始位置)、第一频率资源内用于PUCCH传输的配置 信息，PUCCH传输的配置信息包括以下至少一项：PUCCH传输格式、PUCCH传输对应的符号个数，PUCCH传输的频率资源，PUCCH传输的码资源。
在一种实现方式中，第一设备可以直接通知第一频率资源的配置信息，具体可以通过系统广播信息、RRC专有信令或者物理层信令通知，或者也可以采用其他方式，不做具体限定。在另外一种实现方式中，第一设备可以配置N个第二频率资源，并指示对应第一频率资源的第二频率资源的标识信息来配置第一频率资源。例如第一设备配置了4个第二频率资源，其中第二频率资源索引为0的第二频率资源被标识为包括PUCCH资源的频率资源(具体实现方式同上述实施方式)，则被标识为包括PUCCH资源的第二频率资源可以确定为第一频率资源。
在另外一种实现方式中，第一设备还可以通知用于传输PUCCH的资源索引信息，该资源索引信息可以对应用于PUCCH传输的频率资源信息，例如资源块信息。
具体的，例如，第一设备可以通过SIB1包括的Location And Bandwidth for RedCap UE将第一频率资源的配置信息和/或用于传输PUCCH的资源索引的信息指示给第二设备。应理解，此处广播信息可以是物理广播信道(physical broadcast channel，PBCH)承载的信息，例如为MIB中包括的信息，也可以是调度系统信息块SIB传输的控制信息中包括的信息或者是SIB信息中包括的信息，其中调度SIB传输的控制信息可以承载在PDCCH中，SIB信息可以承载在PDSCH中。
在一种可能的实现方式中，第一设备可以通过RRC专有信令指示第一频率资源的配置信息和/或用于传输PUCCH的资源索引的信息给第二设备。
具体地，第一设备可以在第二设备回退到RRC非激活态时，通过RRC专有信令配置目标频率资源的信息和/或用于传输PUCCH的资源索引的信息，可以用于第二设备在非连接态时可以通过第一频率资源和第一设备进行数据传输。
在一种可能的实现方式中，第一设备还可以通过物理层信令指示第一频率资源的配置信息和/或用于传输PUCCH的资源索引的信息。
优选地，第一设备可以通过SIB1包括的Location And Bandwidth for RedCap UE将第一频率资源的配置信息发送给第二设备，或者通过SIB1包括的其他信息将第一频率资源的配置信息发送给第二设备。或者，第一设备可以在随机接入过程中通过Msg2或者Msg4中包括的控制信息将第一频率资源的配置信息或者PUCCH的资源索引信息发送给第二设备。
S603所述第二设备确定第一频率资源。
示例地，第二设备可以根据接收的第一设备发送的第一指示信息确定第一频率资源。
在一种可能的实现方式中，当该指示信息用于指示传输PUCCH的资源索引时，第二设备需要根据该传输PUCCH的资源索引确定传输PUCCH的资源块，并根据该传输PUCCH的资源块确定第一频率资源，其中，第一频率资源包括该传输PUCCH的资源块。优选地，第一频率资源包括至少2个第一频率资源中频率最高或者频率最低的频率资源。
图7为一种适用于本申请实施例的用于传输PUCCH的频率资源的一种示意图，如图所示，在本实施例中，存在2个第二频率资源，只有一个第二频率资源包括PUCCH传输(对应图中的第二频率资源#1)，第二频率资源#2不包括用于PUCCH传输的频率资源。应理解，在包括PUCCH传输的频率资源内，除了用于PUCCH传输的频率资源之外，也 可以包括用于PUSCH传输的频率资源。在一种可能的实现方式中，在2个第二频率资源中，其中1个第二率资源(即第二频率资源#1)可以对应第一类型终端设备例如RedCap终端设备的上行初始BWP。
在至少2个第二频率资源内，只有一个第二频率资源包括PUCCH资源可以降低控制信道开销。考虑到PUCCH上承载的数据除了可以通过频分复用(frequency division multiplexing，FDM)实现多用户复用，还可以通过码分复用(code division multiplexing，CDM)实现多用户复用，此外，在非连接态，PUCCH上承载的数据传输主要是针对下行数据的HARQ-ACK反馈，综合上述两点，PUCCH传输资源相对于PUSCH传输资源而言，资源开销较小，所以不需要每个第一频率资源内都包括PUCCH资源，这样对于不包括PUCCH的第一频率资源而言，可以保证一定的上行数据传输的峰值速率。此外，如果只有一个第二频率资源包括PUCCH传输，那么对于NR Legacy UE的数据传输性能影响也会比较小。这是因为，至少2个第二频率资源在频率上是FDM的，但也有可能有部分频率资源重叠，如果每个第二频率资源上都包括PUCCH资源，考虑到PUCCH资源如图中所示，一般带宽较小而且为了保证性能分别在第二频率资源的两侧，所以会导致一个载波带宽内存在多处窄带且分布离散的PUCCH资源，进而影响NR Legacy UE的上行数据传输的连续资源大小以及资源块组(resource block group，RBG)的分配。通过本实施例，即使对于NR RedCap UE，存在至少2个第二频率资源，也只有1个第二频率资源包括一个PUCCH资源，进而不仅保证了NR RedCap UE的数据传输性能，也降低了对NR Legacy UE数据传输性能的影响。
应理解，PUCCH传输的数据传输频率资源可以对应为RedCap UE的上行初始BWP。
示例地，所述第二设备可以根据所述第一设备的指示信息确定所述第二频率资源，进一步地，从所述第二频率资源中确定所述第一频率资源。
在一种可能实现的方式中，所述第二设备可以根据接收的所述第一设备发送的指示信息确定所述第二频率资源。
例如，第二频率资源的数量可以与用于第二类型终端设备下行系统信息的传输带宽相关联，带宽越大，数量N越大。
例如，第二频率资源的数量可以与用于传输第二类型终端设备的随机接入上行数据的频率资源相关联。
例如，第二频率资源的数量可以与所述第一设备通知的载波带宽相关联或系统载波所在的频段相关联。
例如，所述第二设备可以根据系统载波的带宽、系统载波所在的频段、用于传输第二类型终端设备的随机接入上行数据的频率资源、用于传输第二类型终端设备的下行系统信息的传输带宽中的一个或者多个确定第二频率资源的数量N，在此，本申请不做限定。其中，用于传输第二类型终端设备的下行系统信息的传输带宽可以为第二类型终端设备对应的下行初始BWP的传输带宽，例如通过MIB中的pdcch-ConfigSIB1控制字段指示的CORESET#0对应的频域资源。
例如，所述第二设备可以根据第二频率资源的数量与用于传输第二类型终端设备的随机接入上行数据的频率资源确定第二频率资源，例如确定每个第二频率资源的频率位置。
例如，所述第二设备可以根据第二频率资源的数量与随机接入前导RACH资源的数 量确定每一个第二频率资源的位置。
S604所述第二设备在第一频率资源内传输PUCCH至所述第一设备。
示例地，所述第二设备确定包括用于传输PUCCH的频率资源的第一频率资源后，可以通过第一频率资源传输PUCCH，第一设备在第一频率资源内，接收来自第二设备的该PUCCH承载的数据。
应理解，本实施例是以第一类型终端设备中的一个终端设备，即，第二设备为例，然而，第一频率资源可以为适用于第一类型终端设备的频率资源。
图8为适用于本申请实施例的上行数据传输的方法的另一种示意性流程图。方法800可以包括如下步骤。
下文实施例，为区分且不失一般性，用第一设备表示网络设备，第二设备表示第一类型终端设备(例如NR RedCap UE)。
应理解，第一设备还可能有其他形式，例如，第一设备与第二设备均可以为第一类型终端设备，或者，第一设备还可以为第二类型终端设备(NR Legacy UE，例如NR eMBB UE)，第二设备可以为第一类型终端设备。此处不做限定。
应理解，在本申请中，第一类型终端设备和第二类型终端设备的主要区别在于带宽能力不同，然而在具体实施过程中，第一类型终端设备和第二类型终端设备的区别不限于带宽能力不同，即，带宽能力不同并不是必选的区别特征。
S801第一设备确定第三频率资源。
示例地，所述第一设备可以确定第三频率资源，其中，第三频率资源为用于传输PUCCH的频率资源或者理解为包括用于传输PUCCH的频率资源，其中，该第三频率资源的数量为1。该第三频率资源的频率资源范围不同于第四频率资源的频率资源范围，所述第四频率资源包括用于传输PUSCH的频率资源。或者，也可以理解为，该用于传输PUCCH的最大频率资源范围不同于用于传输PUSCH的最大频率资源范围。
在一种可能的实现方式中，第三频率资源的频率资源范围小于第四频率资源的频率资源范围。
在现有技术中，终端设备与网络设备在进行数据传输时，用于传输PUCCH的频率资源(可以对应第三频率资源)与用于传输PUSCH的频率资源(可以对应第四频率资源)可以是相同的频率资源。即如果用于传输PUSCH的频率资源内也包括用于传输PUCCH的频率资源，则用于传输PUCCH的最大频率资源范围与用于传输PUSCH的频率资源范围是相同的。例如在现有技术中，终端设备在任何时刻，通过一个激活的BWP与网络设备进行数据传输，在该BWP内PUSCH传输资源的频率资源范围可以为该BWP内包括的频率最低的RB到频率最高的RB所组成的频率资源范围，该BWP内PUCCH传输资源的频率资源范围虽然是可以配置的，但是可配置的频率资源范围也是可以为该BWP内包括的频率最低的RB到频率最高的RB所组成的频率资源范围。另外一般而言，为了保证PUCCH传输的性能，终端设备在时隙内会通过PUCCH跳频的传输方式，使得PUCCH传输获得频率分集增益，例如PUCCH可以通过如下方式确定在时隙内传输的具体频率资源(用PRB表示)，其中在一个时隙内，第一跳PUCCH的频率资源对应的PRB索引为
Figure PCTCN2021110039-appb-000001
第二跳PUCCH的频率资源对应的物理资源块(physical resource block，PRB)索引为
Figure PCTCN2021110039-appb-000002
其中C与PUCCH资源索引和为PUCCH资源分配的初 始循环索引总个数有关，
Figure PCTCN2021110039-appb-000003
为网络设备为终端设备配置的用于PUCCH传输的PRB索引对应的PRB或RB，
Figure PCTCN2021110039-appb-000004
为包括该PUCCH传输的BWP频域资源大小或者也可以理解为BWP频率资源范围，其中BWP频率资源范围或频率资源大小可以用该BWP内包括的PRB或者RB的个数来表示。基于上述公式，可以理解的是，用于传输PUCCH的最大频率资源范围即为包括该PUCCH传输的BWP频率资源大小或者该BWP频率资源范围(例如当
Figure PCTCN2021110039-appb-000005
和C＝0时)。再考虑到该BWP内还可以包括PUSCH传输，网络设备可以调度终端设备的PUSCH频率资源分布在整个BWP内。对于带宽不受限的终端设备，例如NR Legacy终端设备(可以对应本申请实施例中的第二类型终端设备)，由于其带宽可以达到100MHz，因此用于PUCCH传输的最大频率资源范围和用于PUSCH传输的最大频率资源范围可以为均为100MHz，既能实现PUCCH跳频增益又可以保证PUSCH传输性能。但是对于带宽受限或者能力较低的终端设备(对应本申请实施例中的第二设备或者第一类型终端设备)，由于其带宽能力受限，例如只有20MHz，因此为了保证PUCCH跳频传输性能，包括PUCCH传输的第三频率资源范围最大也只能为该终端设备的信道带宽例如20MHz，这样利用现有技术就会导致PUSCH传输的最大频率资源范围也只能为20MHz，这样就会限制PUSCH传输的频选调度增益，一般用于传输PUSCH的最大频率资源范围越大，PUSCH传输被调度的灵活性就越大，就越能获取频选调度增益。基于此，在本申请实施例中，针对第一类型终端设备，用于传输该类型终端设备的PUCCH的频率资源即第三频率资源的频率资源范围可以不同于传输该类型终端设备的PUSCH的频率资源即第四频率资源的频率资源范围。对于第一类型终端设备，通过将第三频率资源与第四频率资源解耦设计，既可以保证PUCCH跳频实现，又可以保证PUSCH传输的频选调度增益，进而可以分别对PUCCH传输和PUSCH传输进行优化，提升第一类型终端设备的数据传输性能。
在一种可能的实现方式中，该第三频率资源的频率资源范围小于第四频率资源的频率资源范围，这样有助于提升PUSCH的频选调度增益。
在一种可能的实现方式中，该第三频率资源的频率资源范围大小不大于第一类型终端设备的带宽能力，例如第一类型终端设备的带宽能力为20MHz，则第三频率资源的频率资源范围为20MHz。这样既可以保证PUCCH跳频增益，又可以实现不对PUCCH传输的符号数有影响。相反地，如果第三频率资源的频率资源范围大小大于第一类型终端设备的带宽能力，则考虑到PUCCH传输，第一类型终端设备需要在第一跳PUCCH之间与第二跳PUCCH之间考虑射频(radio frequency，RF)调谐(retuning)的时间，该RF retuning时间一般会对应几个正交频分复用符号(orthogonal frequency division multiplexing，OFDM)符号，即在RF retuning时间内，第一类型终端设备无法与网络设备(对应本申请实施例中的第一设备)进行数据传输，这样就会导致在有一个时隙内用于PUCCH传输的符号个数变少，进而影响PUCCH传输性能。
图9为适用于本申请实施例的频率资源范围的一种示意图。如图所示，第一类型终端设备用于PUSCH传输的最大频率资源范围与用于PUCCH传输的最大频率资源范围不同，例如，用于PUSCH传输的最大频率资源范围可以大于用于PUCCH传输的最大频率资源范围。其中，在用于PUCCH传输的最大频率资源范围内，没有分配给PUCCH传输的其他资源可以用于PUSCH传输。需要说明的是，用于PUSCH传输的最大频率资源范围是 指在网络设备调度给第一类型终端设备的PUSCH传输资源可以分布在这个最大频率资源范围内包括的任意一个或者多个频域资源单位例如RB上。此外，图9中，在用于PUCCH传输的最大频率资源范围内，用于PUCCH传输的频率资源只是一种示例性的实现方式，第一类型终端设备与网络设备之间的PUCCH传输频率资源还可以分布与用于PUCCH传输的最大频率资源范围中包括对的其他频域资源单位例如RB上。
图10为适用于本申请实施例的频率资源范围的另一种示意图。如图所示，需要说明的是，这里所说的用于PUSCH传输的最大频率资源，可以是指从传输PUSCH可以占用的最小频率位置与可以占用的最大频率位置之间的资源范围。
在本申请实施例中，用于PUSCH传输的最大频率资源范围可以与用于PUCCH传输的最大频率资源范围之间有重叠，或者用于PUSCH传输的最大频率资源范围也可以包括用于PUCCH传输的最大频率范围，或者用于PUSCH传输的最大频率资源范围与用于PUCCH传输的最大频率资源范围之间是没有重叠的，例如以频分复用(frequency division multiplexing，FDM)分布的。
示例性的，本申请实施例中的频率资源可以对应BWP，例如第三频率资源对应包括PUCCH传输的第三BWP，第四频率资源对应包括PUSCH传输的第四BWP。第一类型终端设备通过上述公式确定PUCCH传输资源时，其中第二跳PUCCH传输资源对应的
Figure PCTCN2021110039-appb-000006
中的
Figure PCTCN2021110039-appb-000007
对应的为第三BWP大小(例如第三BWP大小可以为第三BWP包括的频域资源单位个数)。第一类型终端设备确定PUSCH传输资源时，则根据第四BWP确定PUSCH的传输资源位置。进一步地，如果第一设备使能了第一类型终端设备的PUSCH跳频传输，则第一类型终端设备根据第四BWP大小(例如第四BWP大小可以为第四BWP包括的频域资源单位个数)，确定PUSCH跳频传输对应的频率资源。
需要说明的是，在本申请实施例中，用于传输PUCCH的最大频率资源范围并不是指在包括PUCCH传输的频率资源内(例如第三频率资源)，所有的频率资源都用于传输PUCCH，而是指在包括PUCCH传输的频率资源内(例如第三频率资源)，将所有可能用于PUCCH传输的频率资源中，PUCCH传输所对应的频率最低的RB与频率最高的RB对应的频率资源范围看为用于传输PUCCH的最大频率资源范围。以BWP为例，结合上述公式，可以发现在所有可能用于PUCCH传输的频率资源中，PUCCH传输所对应的频率最低的RB与频率最高的RB对应的频率资源范围即为包括PUCCH传输的BWP对应的频率资源范围。
需要说明的是，在本申请实施例中，用于传输PUSCH的最大频率资源范围并不是指在包括PUSCH传输的频率资源内(例如第四频率资源)，所有的频率资源都用于传输PUSCH，而是指在包括PUCCH传输的频率资源内(例如第三频率资源)，将所有可能用于PUSCH传输的频率资源中，PUSCH传输所对应的频率最低的RB与频率最高的RB对应的频率资源范围看为用于传输PUSCH的最大频率资源范围。例如，在第四频率资源范围内，在某个时刻，PUSCH传输可以包括第四频率资源范围内包括的频率最低的RB，在另外时刻，PUSCH传输可以包括第四频率资源范围内包括的频率最高的RB，也就是说，PUSCH传输可以灵活地分布在包括PUSCH传输的第四频率资源范围内，用于传输PUSCH的最大频率资源范围即为第四频率资源对应的频率资源范围。
需要说明的是，在本申请实施例中，所述PUSCH对应的最大频率资源传输范围(即 第四频率资源或第四频率资源范围)可以为第一设备通知的系统上行载波对应的频率范围、或者为第一设备为第二设备配置的上行信道带宽对应的频率范围、或者为第一设备为第二类型终端设备配置的上行初始BWP带宽对应的频率范围中的任一项，或者也可以理解为，第四频率资源可以为第一设备通知的系统上行载波、或者为第二设备对应的上行信道(通过SIB1或者RRC专有信令配置)、或者为第二类型终端设备对应的上行初始BWP中的任一项。其中，所述第二类型终端设备为与第一类型终端设备能力不同的终端设备，例如带宽能力不同的终端设备。由于第二设备可以确定与该第一设备接入，所以该第一设备通过广播信息的方式发送的系统载波上行带宽信息第二设备是可以接收的，并且也可以接收到第一设备为第二类型终端设备配置的上行初始BWP带宽(例如通过接收SIB1确定第二类型终端设备对应的上行初始BWP)。
应理解，在一些具体实施例当中，当所述第一设备可以直接确定传输PUCCH的频率资源时，本步骤为可选步骤，即：所述第一设备可以直接确定传输PUCCH的频率资源，无需确定第三频率资源，进一步地，确定传输PUCCH的频率资源的频率资源范围，该传输PUCCH的频率资源的频率资源范围不同于第四频率资源的频率资源范围，所述第四频率资源包括用于传输物理上行共享信道PUSCH的频率资源。
S802所述第一设备发送指示信息给第二设备。
所述第一设备发送指示信息于所述第二设备，其中，所述指示信息包括第二指示信息和/或第三指示信息。
示例地，当所述第一设备确定传输PUCCH的频率资源时，所述第一设备发送所述第二指示信息，所述第二指示信息用于指示所述PUCCH的频率资源。
示例地，当所述第一设备确定所述第三频率资源时，所述第一设备发送所述第二指示信息，该第二信息用于指示第三频率资源，即，包括PUCCH传输的频率资源。
在一种可能实现的方式中，以第三频率资源对应BWP为例，所述第二指示信息可以对应该BWP的配置信息。可选的，所述第二指示信息用于指示第三频率资源，可以为所述第二指示信息指示以下至少一项：第三频率资源的频率资源位置、第三频率资源的频率资源大小、第三频率资源包括的PUCCH传输配置信息。
所述第一设备发送第三指示信息，所述第三指示信息用于指示所述第四频率资源，即，包括PUSCH传输的频率资源。
在一种可能实现的方式中，以第四频率资源对应BWP为例，所述第三指示信息可以对应该BWP的配置信息。可选的，所述第三指示信息用于指示第四频率资源，可以为所述第三指示信息指示以下至少一项：第四频率资源的频率资源位置、第四频率资源的频率资源大小、第四频率资源包括的PUSCH传输配置信息。
可以理解的是，通过所述第二指示信息和所述第三指示信息分别指示第三频率资源和第四频率资源，可以实现包括PUCCH传输的最大频率资源范围和包括PUSCH传输的最大频率资源范围的解耦配置，这样可以实现对于PUCCH传输和PUSCH传输分别进行优化设计，例如考虑到第一类型终端设备的带宽能力对PUCCH跳频传输的影响，包括PUCCH传输的最大频率资源范围不大于第一类型终端设备的带宽能力。而另一方面，配置不同与第三频率资源范围且用于PUSCH传输的最大频率资源范围，可以保证PUSCH的灵活调度，对于第一类型终端设备的带宽能力对于PUSCH传输性能的影响，只需要保 证每次调度的PUSCH传输资源不超过第一类型终端设备的带宽能力即可，但是调度的PUSCH的频率资源位置可以在不同于第三频率资源的第四频率资源范围内灵活调度，进而保证PUSCH频选调度增益。
考虑到在非连接态时，PUCCH的发送主要是针对Message 4或Message B的HARQ-ACK反馈，因此用于PUCCH传输的最大频率资源范围(即第三频率资源或第三频率资源的资源范围)可以通过随机接入过程中的Message 4或者Message B发送，具体的可以通过调度Message 4或者Message B的PDCCH承载，也可以通过包括Message 4或者Message B的PDSCH承载。
在一种可能的实现方式中，第一设备可以通过Message 4信息和Message B信息中的一种或者两种形式，将用于指示第三频率资源的指示信息发送至第二设备。
在一种可能的实现方式中，在一种可能的实现方式中，第一设备可以通过广播信息通知的方式将第三频率资源指示第二设备。具体的广播信息通知方式的介绍，可以参考S602中的描述，为了简洁，此处不再赘述。
在一种可能的实现方式中，第一设备可以通过RRC专有信令指示第一最大频率资源范围给第二设备。具体的RRC专有信令的介绍，可以参考S602中的描述，为了简洁，此处不再赘述。
在一种可能的实现方式中，第二信息可以直接指示第四频率资源。
在一种可能的实现方式中，第二信息不直接指示第四频率资源，可以指示PUSCH调度资源，PUSCH调度资源可以与第四频率资源相关联。
需要说明的是，在本申请实施例中，第一信息、第二信息可以承载在系统广播信令、RRC专有信令、物理层控制信令或者媒体介入控制(medium access control，MAC)信令中，第一信息和第二信息的通知方式可以相同，也可以不相同。
在本申请实施例中，第一设备可以配置PUCCH传输的最大频率资源范围(或者可以理解为，第一设备配置第三频率资源)，例如通过第二指示信息配置第三频率资源，而用于PUSCH传输的最大频率资源范围可以不用额外定义，直接通过调度PUSCH传输实现，即可以通过调度PUSCH传输的位置来隐式确定用于PUSCH传输的最大频率资源范围。这样实现的好处在于，PUSCH的传输是可以通过数据调度实现的，即使第二设备的带宽能力受限，但只要每次数据调度时，保证调度的PUSCH传输带宽不大于第二设备的带宽能力即可，并且通过调度也可以实现PUSCH的跳频。但是PUCCH传输不同，因为考虑到多用户复用，PUCCH传输不像PUSCH传输那样，可以灵活动态调度，需要考虑一个频率资源范围，来支持PUCCH传输跳频，基于此，第一设备可以只配置PUCCH传输的最大频率范围，既能保证第二设备数据传输性能，又能不增加过多的数据传输最大频率资源范围指示的开销。
S803所述第二设备确定第三频率资源。
示例地，所述第二设备可以直接确定用于传输PUCCH的频率资源。其中该用于传输PUCCH的频率资源包括于第三频率资源内，该第三频率资源的频率资源范围不同于第四频率资源的频率资源范围，该第四频率资源包括用于传输物理上行共享信道PUSCH的频率资源。可选地，该第三频率资源的频率资源范围小于该第四频率资源的频率资源范围。
示例地，所述第二设备可以确定第三频率资源。当所述第二设备确定第三频率资源时， 所述第二设备可以根据第一设备发送的配置信息确定第三频率资源。例如第一设备可以配置PUCCH传输的最大频率资源范围(或者可以理解为，所述第一设备配置第三频率资源)，例如通过第二指示信息配置第三频率资源，而用于PUSCH传输的最大频率资源范围可以不用额外定义，直接通过调度PUSCH传输实现，即可以通过调度PUSCH传输的位置来隐式确定用于PUSCH传输的最大频率资源范围。这样实现的好处在于，PUSCH的传输是可以通过数据调度实现的，即使第二设备的带宽能力受限，但只要每次数据调度时，保证调度的PUSCH传输带宽不大于第二设备的带宽能力即可，并且通过调度也可以实现PUSCH的跳频。但是PUCCH传输不同，因为考虑到多用户复用，PUCCH传输不像PUSCH传输那样，可以灵活动态调度，需要考虑一个频率资源范围，来支持PUCCH传输跳频，基于此，第二设备可以根据第一设备配置的PUCCH传输的最大频率范围，确定PUCCH传输频率资源范围，并根据被调度的PUSCH传输资源与用于PUSCH传输的最大频率资源范围之间的关联关系，确定第四频率资源对应的频率资源范围，这样既能保证第二设备数据传输性能，又能不增加过多的数据传输最大频率资源范围指示的开销。
示例地，所述第二设备还可以根据所述来自第一设备的第二指示信息直接确定所述用于传输PUCCH的频率资源。
在一种可能的实现方式中，可以将用于PUCCH传输的最大频率资源范围(即第三频率资源)定义为第二设备对应的上行初始BWP。
在一种可能的实现方式中，随机接入前导资源对应的最大频率资源的传输范围大于第三频率资源或大于第三频率资源的频率资源范围。
所述第二设备发送随机接入前导资源所对应的最大频率资源范围可以与用于PUSCH传输的最大频率资源范围(即第四频率资源对应的频率资源范围)、用于PUCCH传输的最大频率资源范围(即第三频率资源对应的频率资源范围)均不同。目前NR系统中每个随机接入前导资源序列对应的传输带宽都不会超过20MHz，也就是说第二设备可以直接利用现有随机接入前导资源实现初始接入，尽管考虑所有的频分复用RACH时机(FDMed RACH occasion，FDMed RO)频率资源，其频率资源范围会超过第二设备的传输带宽，但是就每个随机接入前导资源传输而言，其传输带宽都在第二设备带宽能力范围内，另外，针对PUSCH传输，如上所述可以通过调度的方式，实现更大频率资源范围内的传输，只需要保证每次PUSCH传输带宽不超过第二设备带宽能力就可以，但对于PUCCH而言，需要考虑定义频率资源范围，因此，可以针对每个信道独立考虑其所对应的最大频率资源范围的配置，保证每个信道的数据传输性能。
在一种可能的实现方式中，所述第二设备可以接收第四指示信息，所述第四指示信息用于指示用于第一类型终端设备的随机接入前导资源对应的最大频率资源范围，例如，所述第四指示信息所述信息指示FDMed RO，则FDMed RO对应的频率资源范围可以对应用于第一类型终端设备的随机接入前导资源对应的最大频率资源范围。其中用于第一类型终端设备的随机接入前导资源也可以用于第二类型终端设备的随机接入，此时，所述第四指示信息还可以为指示用于第二类型终端设备的随机接入前导资源对应的最大频率资源范围。即第一类型终端设备对应的随机接入前导资源最大频率资源可以与第二类型终端设备对应的随机接入前导资源最大频率资源范围相同。
在一种可能的实现方式中，在本申请实施例中，第一类型终端所对应的随机接入前导 资源对应的最大频率资源范围可以与第四频率资源范围相同。可以理解的是，在这种情况下，所述第四指示信息即为所述第三指示信息，或者所述第三指示信息和所述第四指示信息还是不同的信息，但是指示了相同的范围。
在本申请实施例中，通过对第一类型终端设备对应的随机接入前导资源对应的最大频率资源范围、包括PUCCH传输的第三频率资源以及包括PUSCH传输的第四频率资源分布配置，可以针对不同信道适配于信道特征分别设计和优化，进而满足第一类型终端设备特别是具有低带宽能力的第一类型终端设备的各个信道的传输需求。
图11为适用于本申请实施例的频率资源范围的另一种示意图。如图所示，对于所述第二设备而言，例如在初始接入阶段，用于随机接入前导资源传输的最大频率资源范围、用于PUCCH传输的最大频率资源范围、以及用于PUSCH传输的最大频率资源范围对应的大小可以彼此不相同，进一步的，可以将其中一个最大频率资源作为第二设备对应的上行初始BWP。
S804所述第二设备在第三频率资源内传输PUCCH至所述第一设备。
所述第二设备在第三频率资源内传输PUCCH至所述第一设备。
示例地，所述第二设备确定用于传输PUCCH的频率资源后，在第三频率资源内传输PUCCH。对应地，第一设备在第三频率资源内，接收来自所述第二设备的PUCCH。
在本申请实施例中，所述第二设备发送随机接入前导资源所对应的最大频率资源范围可以与用于PUSCH传输的最大频率资源范围、用于PUCCH传输的最大频率资源范围均不同。对于所述第二设备而言，例如在初始接入阶段，用于随机接入前导资源传输的最大频率资源范围、用于PUCCH传输的最大频率资源范围、以及用于PUSCH传输的最大频率资源范围对应的大小可以彼此不相同，在一种可能实现的方式中，可以将其中一个最大频率资源作为第二设备对应的上行初始BWP。
需要说明的是，在本申请实施例中，第一设备还会配置第二类型终端设备对应的PUCCH传输的最大频率资源范围和PUSCH传输的最大频率资源范围。例如在随机接入过程中，第一设备可以配置第二类型终端设备对应的上行初始BWP对应PUCCH传输的最大频率资源范围和PUSCH传输的最大频率资源范围，即对于第二类型终端设备而言，PUCCH传输对应的最大频率资源与PUSCH传输对应的最大频率资源可以是相同的频率资源。可以理解的，对于第二类型终端设备而言，用于配置PUCCH传输对应的最大频率资源和用于配置PUSCH传输对应的最大频率资源的配置信息可以是同一个信息。可选地，第二类型终端设备对应的用于传输PUCCH的最大频率资源(也是用于第二类型终端设备传输PUSCH的最大频率资源)可以作为本申请实施例中的第四频率资源，即第一类型终端设备对应的用于传输PUSCH的最大频率资源。可选地，第一设备用于配置第二类型终端设备对应的PUCCH传输的最大频率资源范围和PUSCH传输的最大频率资源范围的配置信息可以与上述中的第二指示信息、第三指示信息、第四指示信息均不相同。
在本申请实施例中，频率资源由N个连续/非连续的PRB/RB组成，N为正整数。示例的，所述频域资源由N个连续的PRB/RB组成。例如，频率资源可以为BWP。
在本申请实施例中，所述N个第二频率资源中包括M个用于传输PUCCH的频率资源可以是网络设备(作为本申请实施例中第一设备的一种实现方式)使能的。例如当网络设备不使能该特性时，对于第一类型终端设备而言，用于传输PUCCH的频率资源个数等 于用于传输第一类型终端设备的上行数据的第二频率资源的个数，即M＝N。
在本申请实施例中，第三频率资源的频率资源范围不同于第四频率资源的频率资源范围可以是网络设备(作为本申请实施例中第一设备的一种实现方式)使能的。例如当网络设备不使能该特性时，第三频率资源的频率资源范围等于第四频率资源的频率资源范围。
需要说明的是，本申请实施例中的第一频率资源、第二频率资源、第三频率资源以及第四频率资源不仅可以用于传输第一类型终端设备在RRC空闲态的上行数据，也可以用于传输第一类型终端设备在RRC连接态或者非激活态的上行数据。
