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。
本申请实施例可以应用于各种通信系统，例如无线局域网系统(Wireless Local Area Network，WLAN)、窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)、卫星通信、第五代(5th generation，5G)系统或者将来出现的新的通信系统等。
移动通信技术已经深刻地改变了人们的生活，但人们对更高性能的移动通信技术的追求从未停止。为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，5G移动通信系统应运而生。国际电信联盟(international telecommunication union，ITU)为5G以及未来的移动通信系统定义了三大类应用场景： 增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。
典型的eMBB业务有：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用，这些业务的主要特点是要求超高可靠性、低延时，传输数据量较少以及具有突发性。典型的mMTC业务有：智能电网配电自动化、智慧城市等，主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感，这些mMTC终端需要满足低成本和非常长的待机时间的需求。
不同业务对移动通信系统的需求不同，如何更好地同时支持多种不同业务的数据传输需求，是当前5G移动通信系统所需要解决的技术问题。例如，如何同时支持mMTC业务和eMBB业务，或者同时支持URLLC业务和eMBB业务。
5G标准对mMTC的研究还没有广泛开展。
目前，标准中将mMTC业务的用户设备(user equipment,UE)称为低复杂度的UE(reduced capability UE，REDCAP UE)，或窄带宽用户设备，或物联设备，或低端智能手持终端。该类UE可能在带宽、功耗、天线数等方面比其他UE复杂度低一些，如带宽更窄、功耗更低、天线数更少等。该类UE也可以称为轻量版的终端设备(NR light，NRL)。mMTC用户设备支持的最大带宽小于100MHz。需要说明的是，本申请中的mMTC用户设备不只是机器类通信的设备，也可以是智能手持终端。
本申请实施例应用的移动通信系统的架构示意图。如图1所示，该移动通信系统包括无线接入网设备120即网络设备120和至少一个终端设备(如图1中的终端设备130和终端设备140和终端设备150)。终端设备通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网设备连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端设备可以是固定位置的，也可以是可移动的。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。本申请的实施例对该移动通信系统中包括的核心网设备、无线接入网设备和终端设备的数量不做限定。

为了便于理解本申请，对随机接入过程进行简单描述。随机接入过程如下：
终端设备搜索同步信号和物理广播信道(Synchronization Signal and PBCH，SSB)，终端设备通过搜索SSB，获取网络设备发送的主信息块(Master information block，MIB)。终端设备根据MIB获取控制资源集合(Control resource set，CORESET)的时域资源与频域资源，终端设备可以在CORESET上检测调度系统信息块(System information block，SIB)的下行控制信息(Downlink control information，DCI)，在DCI指示的时频位置上接收SIB1，如此，即可接收SIB1中指示的初始上行链路带宽部分(initial uplink bandwidth part，Initial UL BWP)，初始下行链路带宽部分(initial downlink bandwidth part，Initial DL BWP)，随机接入前导列表，随机接入时机列表等信息。
根据SIB1，终端设备在与SSB关联的随机接入时机(RACH occasion，RO)资源中发送承载随机接入前导的物理随机接入信道信道，(physical random-access channel，PRACH，即Msg1)；
如果基站成功接收到了随机接入前导并且允许UE接入，则在预配置的随机接入响应(Random access response，RAR)的窗口(window)内，给UE发送RAR，即Msg2；
同时，UE在预配置的RAR window内，监听在物理层下行控制信道(Physical downlink control channel，PDCCH)上传输的下行控制信息(Downlink control information，DCI)，该DCI用于指示UE从物理下行共享信道(Physical downlink shared channel，PDSCH)承载的媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU) 中获取RAR信息。
应理解，如果由于不同UE之间选择的随机接入前导冲突，或者信道条件差等原因，导致基站无法接收到preamble前导，则基站不会发送RAR信息，那么UE在RAR window中就不会检测到DCI和MAC RAR，那么本次随机接入失败。
终端在成功检测到DCI后，接收随机接入响应RAR(即Msg2)，按照随机接入响应中的上行授权UL grant指示的时频资源发送物理上行共享信道(Physical Uplink Shared CHannel，PUSCH，即Msg3)，网络设备再向终端设备发送DCI，该DCI指示承载竞争解决消息，即Msg4，的时频资源，终端设备检测检测该DCI，并接收Msg4。
需要注意的是，在无线资源控制(Radio Resource Control，RRC)建立连接之前，UE需要在CORESET 0内接收：调度SIB1的PDCCH，承载SIB1的PDSCH,调度SI的PDCCH，承载SI的PDSCH，调度Msg2的PDCCH，承载Msg2的PDSCH，调度Msg3的PDCCH，调度Msg4的PDCCH,承载Msg4的PDSCH。在无线资源控制(Radio Resource Control，RRC)建立连接之前，UE需要在initial UL BWP内发送Msg1，和承载Msg3的PUSCH，以及对Msg4反馈的PUCCH。

为了便于理解本申请实施例，提前对相关名词作一解释。
本申请各实施例中对于资源有不同的描述，比如，第一资源，又如，带宽资源。
第一资源可以是上行BWP，可以是下行BWP,可以是初始下行BWP，可以是初始上行BWP。第一资源的大小等于或小于第一终端设备支持的最大信道带宽。第一控制资源集表述为CORESET a，例如，在RRC连接建立之前，CORESET a为CORESET 0；例如，在RRC连接建立之前或RRC连接建立之后，CORESET a也可以是公共CORESET，公共CORESET的至少一个RB可以不在CORESET 0的范围内，即CORESET a和CORESET 0可以为不同的CORESET。

应理解，第一资源与带宽资源可以等同，各实施例中确定资源的方法对于第一资源和带宽资源均可以适用。
时间单元可以是子帧，无线帧，时隙，迷你时隙，符号，微秒，毫秒，秒中的任一种。
上行信息：包括随机接入信道(随机接入前导)，随机接入过程中的消息3，对竞争解决消息反馈的物理上行控制信道中的一种或多种。
随机接入过程中的消息3：包括承载Msg3的PUSCH的第一次传输(Msg3的初传)，承载Msg3的PUSCH的第一次传输的第一跳传输(Msg3的初传的第一跳传输)，承载 Msg3的PUSCH的第一次传输的第二跳传输(Msg3的初传的第二跳传输)，承载Msg3的PUSCH的第一次传输之后的传输(Msg3的重传或Msg3的重复)，承载Msg3的PUSCH的第一次传输之后的传输的第一跳传输(Msg3的重传或Msg3的重复的第一跳传输)，承载Msg3的PUSCH的第一次传输之后的传输的第二跳传输(Msg3的重传或Msg3的重复的第二跳传输)中的一种或多种。
对竞争解决消息反馈的物理上行控制信道：包括承载Msg4的PUCCH的第一次传输(初传)，承载Msg4的PUCCH的第一次传输的第一跳传输，承载Msg4的PUCCH的第一次传输的第二跳传输，承载Msg4的PUCCH的第一次传输之后的传输(重传或重复)，承载Msg4的PUCCH的第一次传输之后的传输的第一跳传输，承载Msg4的PUCCH的第一次传输之后的传输的第二跳传输中的一种或多种。
UE在下行BWP中接收下行控制信息、下行共享信道、解调参考信号、定位参考信号等中的一种或多种。UE在上行BWP中发送上行控制信道、上行共享信道、随机接入信道、上行解调参考信号、探测参考信号中的一种或多种。对于有能力同时进行下行接收和上行传输的UE，该UE在上行BWP发送上行信息，同时在下行BWP接收下行信息，上行BWP和上行BWP的频率范围可以不同。例如，频分复用FDD UE有能力同时进行下行接收和上行传输。例如，TDD上下行解耦的UE有能力同时进行下行接收和上行传输。以UE在RRC建立连接之前为例，UE需要在initial UL BWP内发送Msg1，承载Msg3的PUSCH，承载Msg3的重传的PUSCH，对Msg4反馈的PUCCH中的一种或多种。
UE在随机接入信道机会(RACH occasion，RO)中发送随机接入前导。时域上，对于一个PRACH传输机会，最多可以频分复用配置8个RACH occasion，以PRACH的子载波间隔为30KHz为例，一个RO带宽为4.32MHz，频分复用的8个RO的总带宽为34.56MHz。SSB与RO存在映射关系，每个SSB的RO数会通过系统信息块1中的参数来配置，并且SSB按照先时域后频域的方式映射到RO，以每2个RO映射同一个SSB为例，子载波间隔为30KHz，频分复用的RO数为8个，SSB的数量为8个。频分复用的8个RO的频率范围可能会超过低复杂度终端设备支持的最大信道带宽。UE接入小区时会获取其中一个SSB，并且在该SSB对应的RO发送PRACH。例如，UE发送PRACH之后，其后紧接着要发送承载Msg3的PUSCH，若发送Msg1所在的的频率范围与发送承载Msg3的PUSCH所在的频率范围在频率上对应的总频率范围超过UE的最大信道带宽，则需要在发送PRACH后进行频率调谐，进而发送承载Msg3的PUSCH。相邻的下行信息的接收，对于FDD UE或TDD上下行解耦的UE同样存在频率调谐的问题。
频率调谐会降低数据传输可用的符号、降低资源利用效率、增加UE的功耗和UE实现的复杂度。另外，若按照任意RB都可以作为带宽资源的起始RB，并且任意资源大小都可以作为带宽资源的长度的方式来配置带宽资源，由于低复杂度终端设备支持的最大信道带宽小于载波带宽，低复杂度终端设备需要存储所有的可能的配置。这样会造成UE计算带宽资源的复杂度过高。
为解决上述问题，本申请的一个实施例，提出了一种传输信息的方法，如图2所示，
200：网络设备向第一终端设备指示信息，指示信息可以用于指示第一资源，指示信息可以包括第一参考点，也可以包括第一带宽，第一参考点可以用于确定第一资源的位置，第一带宽可以是第一资源的带宽的大小。
应理解，200是可选的，第一参考点和第一带宽也可以是预定义的，本申请对此不作限定。
201：第一终端设备根据第一参考点和/或第一带宽确定第一资源，第一资源的大小等于或小于第一终端设备支持的最大信道带宽；
202：第一终端设备在第一资源中发送上行信息或接收下行信息。
应理解，指示信息可以一次指示第一参考点和第一带宽，如图3，也可以分次指示，如图4。可以是一个指示信息指示第一参考点，另一个指示信息指示第一带宽，或者，一个指示信息指示第一带宽，另一个指示信息指示第一参考点，也可以只指示第一参考点，也可以只指示第一带宽。
应理解，也可以将第一参考点和/或第一带宽的信息携带在其它信息中，其他等效的替代方案也在本申请的保护范围之内。
示例地，网络设备可以先接收第一终端设备的信道状态信息(Channel State Information，CSI)，CSI中包括有子带的大小信息，网络设备根据该子带的大小确定第一终端设备第一资源的带宽。
应理解，第一参考点可以作为第一资源的位置，也可以根据第一参考点和第一偏移量确定第一资源的位置。
第一带宽，第一偏移量和第一参考点也可以是预定义的，本申请对此不作限定。
第一带宽可以根据CSI上报的子带大小、子载波间隔、第一终端设备支持的带宽中的一项或多项确定。
其中，第一偏移量也可以根据CSI上报的子带大小、子载波间隔、第一终端设备支持的第一带宽中的一项或多项确定。
具体地，可以通过第一配置信息配置第一带宽，第二配置信息配置第一偏移量，第三配置信息配置第一参考点。第一配置信息，第二配置信息，第三配置信息可以承载于不同的信息。也可以承载于同一个信息，比如，可以承载于SIB1。
一种可能的实现方式，根据第一终端设备支持的带宽，确定第一资源。
第一终端设备支持的带宽可以是信道带宽，也可以是信道带宽对应的传输带宽。比如，第一终端设备支持的带宽可以是5MHz，10MHz，20MHz，或者5MHZ，10MHz，20MHz，在不同子载波间隔下对应RB数。
第一终端设备支持的带宽为第一信道带宽时，第一信道带宽为第一终端设备支持的最大信道带宽中的一个带宽。例如，第一信道带宽可以是第一终端设备支持的最大信道带宽中的最小带宽。比如，第一终端设备上报支持的最大信道带宽可以是5MHz，10MHz，15MHz，20MHz，第一信道带宽可以是5MHz，10MHz，15MHz，20MHz中的一个带宽，其中第一终端设备上报支持的最大信道带宽中的最小带宽为5MHz，即第一信道带宽也可以是5MHz。
一种可能的实现方式，可以根据第一终端设备支持的带宽的正整数倍确定第一带宽。例如，根据5MHz的正整数倍，确定第一带宽。第一终端设备支持的带宽可以是第一传输带宽，第一传输带宽为第一信道带宽在不同子载波间隔下对应的资源块数。例如，不同子载波间隔下，第一信道带宽和第一传输带宽的对应关系如表格一所示。
子载波间隔为15KHz时，对应5MHz的带宽，第一传输带宽为25个RB。对应地， 可以根据25个RB的正整数倍，比如25个RB，50个RB，75个RB，100个RB等，确定第一带宽。又如，子载波间隔为30KHz时，5MHz对应的第一传输带宽为11个RB，则可以根据11个RB的正整数倍，确定第一带宽。又如，可以根据10个RB的正整数倍，确定第一带宽。又如，子载波间隔为60KHz时，10MHz对应的第一传输带宽为11个RB。则可以根据11个RB的正整数倍确定带宽。
表一 子载波间隔与第一终端设备支持的带宽对应的RB数的关系表
Figure PCTCN2022077812-appb-000001
应理解，表一只是一种示例，本申请对此不做限定。
一种可能的实现方式，根据第一参考点和第一偏移量确定第一资源的额位置时，第一偏移量的确定方法与上述实施例的方法相同，此处不再赘述。
另一种可能的实现方式，第一终端设备支持的带宽为第一传输带宽时，第一传输带宽的正整数倍之外的资源块用于发送第一控制信道。第一传输带宽的正整数倍之外的资源块包括第一传输资源和/或第二传输资源，如图5所示，第一传输资源为第二资源的索引最小的M1个资源块，所述第二传输资源为第二资源的索引最大的M2个资源块；其中，M1和M2为正整数，第二资源为第二类型的终端设备的BWP，或者不同子载波间隔时对应的载波带宽。
示例地，第一控制信道可以包括对Msg4的反馈的PUCCH的第一跳传输，也可以是对Msg4的反馈的PUCCH的第二跳传输。第一控制信道也可以是对Msg4的反馈的PUCCH的第一跳传输和第二跳传输。
具体地，子载波间隔为15KHz时，对应5MHz的第一传输带宽为25个RB，最大信道带宽50MHz对应的RB数为270个RB，第一传输带宽的正整数倍作为第一带宽，第一传输带宽的正整数倍作为第一偏移量，例如，第一带宽可以是25个RB，第一偏移量可以是25个RB，子载波间隔为15KHz时，最多能够配置10个第一带宽，共250个RB，最大信道带宽50MHz对应的RB数为270个RB，剩余的20个RB分布在载波的两端。则第一传输资源可以是第二资源中索引最小的M1个资源块，第二传输资源可以是第二资源中索引最大的M2个资源块。
上述方案以第一带宽为粒度，一方面可以大程度减小带宽的可选范围，另一方面可以作为UE节约能耗情况下配置的最小带宽。
一种可能的实现方式，根据CSI上报的子带大小确定第一资源和/或第一偏移量。
示例地，CSI上报的子带的大小为4个RB的倍数。例如，网络设备以CSI上报的子带的大小确定第一带宽，第一带宽可以是4个RB的倍数，如图6所示，可以是4个RB。也可以是8个RB、16个RB等等。又如，网络设备以CSI上报的子带的大小确定第一偏移量，第一偏移量可以是4个RB的倍数，可以是4个RB、8个RB、16个RB等等。
相比于非4个RB的倍数的带宽，UE上报子带数减少，减少UE上报的复杂度。
一种可能的实现方式，根据CSI上报的子带大小和控制资源集资源分配粒度大小，确定第一资源和/或第一偏移量。可以根据CSI上报的子带大小和控制资源集资源分配粒度大小的公倍数，确定第一资源和/或第一偏移量。例如，CSI上报的子带大小可以是4个RB，CORESET资源分配粒度可以是6个RB，根据以上两项的RB数的公倍数，比如，可以是12的倍数个RB作为第一带宽，和/或作为第一偏移量。
一种可能的实现方式，可以根据CSI上报的子带大小和资源块组粒度大小，确定第一资源和/或第一偏移量。根据CSI上报的子带大小和资源块组粒度大小的公倍数，确定第一资源和/或第一偏移量。例如，CSI上报的子带大小可以是4个RB，资源块组可以包括2的幂次方个RB，以上两项包含的RB数的公倍数，比如，可以是4的倍数个RB作为第一带宽，和/或作为第一偏移量。
又一可能的实现方式，根据CSI上报的子带大小，控制资源集资源分配粒度大小，和资源块组粒度大小，确定第一资源和/或第一偏移量。根据CSI上报的子带大小，控制资源集资源分配粒度大小，和资源块组粒度大小的公倍数，确定第一资源和/或第一偏移量。例如，CSI上报的子带大小可以是4个RB，CORESET资源分配粒度可以是6个RB，资源块组可以包括2的幂次方个RB，以上几项包含的RB数的公倍数，比如，可以是12的倍数个RB作为第一带宽，和/或作为第一偏移量。
上述方案根据CSI上报的子带大小确定第一资源的带宽，解决了子带与第一资源的带宽不匹配会导致UE上报的子带数增加的问题，增加了CORESET资源分配粒度和资源块组作为配置第一带宽的依据，同时避免了第一带宽与CSI上报的子带大小，CORESET的资源分配，数据信道type 0的资源分配出现不匹配的情况，避免了资源的浪费，如图7，降低了UE上报CSI的复杂度。
应理解，上述方案可以与前文所述的实现方式相互结合。比如，在25个RB范围内，可以采用12的倍数作为第一偏移量，例如24个RB，可以避免前文所述的不匹配问题，且可以减小带宽指示范围。
一种可能的实现方式，上述实施例中的第一带宽和第一偏移量可以与子载波间隔相关联。第一带宽与子载波间隔存在第一关联关系；和/或，第一偏移量与子载波间隔存在第二关联关系。例如，第一关联关系可以是：子载波间隔越大，第一带宽越小。又如，第二关联关系可以是：子载波间隔越大，第一偏移量越小。第一关联关系还可以是：子载波间隔越大，第一资源的大小成比例减小，又如，第二关联关系可以是：子载波间隔越大，第一偏移量成比例减小。
示例地，对于15KHz，第一偏移量可以为24个RB，对于30KHz，第一偏移量可以为12个RB，对于60Khz第一偏移量可以为6个RB，等等。例如，对于15KHz，第一偏移量可以为24个RB，对于30KHz，第一偏移量可以为6个RB，对于60Khz第一偏移量可以为4个RB，等等。例如，对于15KHz，第一偏移量可以为12个RB，对于30KHz，第一偏移量可以为6个RB，对于60Khz第一偏移量可以为4个RB，等等。
该方案考虑了子载波间隔不同时，相同带宽包含的RB数不同，当NR支持不同子载波间隔的场景下，也可以用本申请的方案配置第一资源。
一种可能的实现方式，第一终端设备根据第一参考点确定第一资源。
示例地，第一终端设备可以接收指示信息，指示信息指示第一参考点，第一参考点是 可以是第二资源的第一个RB，第二资源的中心频率或中心子载波，第二资源的最后一个RB，公共资源块0，Point A中的一种或多种。指示信息可以承载于SIB1或调度SIB1的PDCCH中。
第二资源是为第二类型终端设备配置的资源，且第二资源包含的资源块数能够大于第一终端设备的最大信道带宽对应的资源块数。例如，第二资源是载波带宽或载波在不同子载波间隔时对应的RB数，第二资源也可以是第二类型终端设备的BWP。
应理解，第一终端设备也可以通过预定义的方式确定第一参考点，第一参考点可以是是第二资源的第一个RB，第二资源的中心频率或中心子载波，第二资源的最后一个RB，公共资源块0，Point A中的一种或多种。
一种可能的实现方式，可以通过信令指示第二资源起始RB和结束RB的位置，如图8所示，多个候选带宽中可以有2个候选带宽以第二资源的结束RB作为参考点，另外3个候选带宽可以以第二资源的起始RB作为参考点。
另一可能的实现方式，可以通过信令指示第二资源起始RB的位置，或者结束RB的位置，通过指示的该参考点依次确定候选带宽。
应理解，此处的个数，以及个数与起始RB、结束RB的对应关系只是一种示例，对此不作限定。
另一种可能的实现方式，可以采用CRB 0(Point A)作为参考点，根据参考点确定第一资源的起点。
该方案为第一资源的配置提供了参考点，能够避免第一资源在某些频域上占用不足一个RB造成的资源浪费的情况。
又一种可能的实现方式，在第一终端设备与第二终端设备共享BWP的情况下，联合考虑第二资源的位置与CRB的起始位置来确定参考点，可以将与CRB资源对齐的频率位置作为参考点，例如图9中的(a)所示，参考点不一定是第二资源的起始或结束RB位置。
该方案能够灵活确定第一资源起始位置，降低了指示的开销，并且避免了资源分配不匹配的问题。
再一种可能的实现方式，根据CSI上报的子带大小(subband size)，CORESET资源分配粒度，资源块组(RBG)，子载波间隔，第一终端设备支持的最小信道带宽中的一种或多种配置第一资源的频域偏移量，该偏移量可以是第一资源的起始位置相对于第二资源的位置偏移的RB。
示例地，如图9中的(b)所示，当第一参考点(Start_RB)为第二资源的起始RB的位置时，第一资源的起始位置可以是MOD(Start_RB+第一偏移量,BW)，
当Start_RB为第二资源的结束RB的位置时，第一资源的起始位置可以是MOD(Start_RB+第一偏移量,BW)，或者MOD(BW，Start_RB-第一偏移量)。其中，BW为第二资源的带宽，或者为载波带宽。
其中，第一参考点和第一偏移量可以根据前文的实施例中的方案来确定，在此不再赘述。例如，第一偏移量可以是25个RB的整数倍，Start_RB+第一偏移量的RB位置可以为index*25，Index为{0,1,2,3,4,5,6,7,8,9,10}。
若没有指示第一偏移量，则默认以Start_RB为第一资源的起始位置。
第一终端设备接收网络设备发送的第二信息，第二信息指示第一带宽，第一参考点，第一偏移量中的至少两种。即网络设备对第一带宽，第一参考点，第一偏移量中的至少两种进行联合编码。例如，第一带宽可选5MHz，10Mhz，20MHz(或者25RB，50RB，100RB)，第一偏移量为25个RB的整数倍，则共需指示30个状态，需要5bit
本方案综合考虑指示的复杂度与灵活性，可以降低用于第一资源的比特开销，同时降低UE的计算复杂度。
本申请的另一实施例，第一参考点作为第一带宽位置的参考点，可以是第一随机接入资源的位置，也即根据第一随机接入资源的位置确定第一资源的位置，第一终端设备在第一资源内发送第一上行信息。
其中，第一资源的大小(也即第一带宽)等于或小于第一终端设备支持的最大信道带宽；第一随机接入资源为第一终端设备可用的随机接入资源。第一终端设备可用的随机接入资源可以是网络设备配置给第一终端设备的随机接入资源。

应理解，第一随机接入资源的大小可以是预定义的。
第一资源的位置包括第一资源的第一个RB；或者，第一资源的位置包括第一资源的最后一个RB；或者，第一资源的位置包括第一资源的中心RB；或者，第一资源的位置包括第一资源的第一个RB的第一个子载波；或者，第一资源的位置包括第一资源的最后一个RB的第一个子载波；或者，第一资源的位置包括第一资源的中心RB的第一个子载波；或者，第一资源的位置包括第一资源的第一个RB的最后一个子载波；或者，第一资源的位置包括第一资源的最后一个RB的最后一个子载波；或者，第一资源的位置包括第一资源的中心RB的最后一个子载波。
本申请用第一位置代表第一资源的参考位置。
应理解，第一随机接入资源的位置可以是预定义的，也可以是信令指示的。
示例地，第一终端设备根据预定义的第一随机接入资源的位置，确定第一资源的位置。例如，预定义的第一随机接入资源的位置可以是第n个随机接入资源的位置，对应的随机接入资源的索引为n-1，n为正整数。如图10所示，预定义的第一随机接入资源的位置可以是第4个随机接入资源的最后一个RB或最后一个RB的最后一个子载波。预定义的第一随机接入资源的位置也可以是第5个随机接入资源的第一个RB或第一个RB的第一个子载波。第一资源的位置可以是以预定义的第一随机接入资源的位置为起始位置。第5个随机接入资源的第一个RB或第一个RB的第一个子载波，确定为第一资源的第一个RB或第一个RB的第一个子载波。第一资源的位置也可以是以预定义的第一随机接入资源的位置为结束位置。
第一随机接入资源的位置也可以是第一信令指示的。第一信令可以承载于系统信息块1(SIB1)，调度SIB1的DCI，随机接入响应(Random access response，RAR)，调度RAR的DCI，调度Msg3上行授权，Msg3，竞争解决消息，调度竞争解决消息的DCI中的一种。第一信令也可以是以上信息中的比特或比特状态。
本申请的一个实施例，提供了一种传输信息的方法，如图11所示：
1101：网络设备向第一终端设备发送第一信息和第一参数，该第一信息用于指示M个带宽资源，其中M是正整数，第一参数为一个时间单元内频分复用的随机接入信道机会的个数，第一终端设备为第一类型终端设备，M个带宽资源中的每个带宽资源的大小等于或小于述第一终端设备支持的最大信道带宽。
应理解，1101是可选的，第一信息和第一参也可以是预定义的。
1102：第一终端设备获取第一信息和第一参数，第一终端设备根据第一信息和第一参数确定第一带宽资源；
应理解，第一信息可以是系统信息。例如，系统信息块1(system information block 1，SIB1)。
1103：第一终端设备在第一带宽资源中发送上行信息或接收下行信息。
具体地，第一参数可以包含在随机接入信道配置信息中。
随机接入信道配置信息还可以包含PRACH的其他信息。例如，随机接入信道机会为PRACH transmission occasion，第一终端设备通过PRACH transmission occasion发送随机接入前导。又如，第一终端设备能够发送PRACH的时隙，在时域能够包括一个或多个PRACH transmission occasion，每个PRACH transmission occasion为一个时间单元。
第一参数可以指示一个PRACH occasion内能够在频率上频分复用的PRACH transmission occasion的个数。一个时隙可以包括一个或多个时间单元，当一个时隙包括多个时间单元时，一个时间单元可以是s个符号，s为大于1的正整数，则第一参数可以指示一个时间单元内能够在频率上频分复用的PRACH transmission occasion的个数，第一参数的值可以是1,或2,或4,或8等。
例如，第一参数的值为8，则一个时间单元内频分复用的随机接入信道机会的个数是8，这8个随机接入信道机会可以按照频率资源从低往高的顺序将索引排列为0～7。
一种可能的实施方式，M个带宽资源中的每个带宽资源的大小可以是预定义的，也可 以是网络设备指示的。例如每个带宽资源的大小可以是5MHz，或是5MHz在不同子载波间隔下对应的RB数，或是10MHz，或是10MHz在不同子载波间隔下对应的RB数，或是20MHz，或是20MHz在不同子载波间隔下对应的RB数。
一种可能的实施方式，M＝2,且2个带宽资源中一个带宽资源包含随机接入信道机会{0,1,2,3}的资源，另一个带宽资源包含随机接入信道机会{4,5,6,7}的资源。2个带宽资源中的每个带宽资源不超过第一终端设备支持的最大信道带宽的基础上，2个带宽资源能够包含所有的随机接入信道机会的资源，第一终端设备能够根据带宽资源确定发送PRACH时的中心频率，能够减少频率调谐的次数。
又一种可能的实施方式，M>1,第一终端设备可以获取第一信令，第一信令指示了M个带宽资源中的第一个带宽资源，M个带宽资源中的其他M-1个带宽资源根据所述第一个带宽资源确定。
例如，第一个带宽资源为按照频率资源的位置从低往高的顺序排列时，位置最低的一个带宽资源。可以通过配置起始位置和配置资源大小来配置第一个带宽资源。其余的M-1个带宽资源可以以第一个带宽资源的结束资源块作为起始资源块，依次排序，这样M个带宽资源可以依次确定。带宽资源的配置不需要考虑RO的位置，更加灵活。
一种可能的实现方式，第一参数的值大于4时，且M＝1时，该带宽资源是第一终端设备的第一带宽资源，该第一带宽资源可以包含预定义的N个随机接入信道机会的资源，其中第一参数个随机接入信道机会包括N个随机接入信道机会,其中N是正整数。
例如，第一参数的值为8，且第一信息为第一终端设备只配置了1个带宽资源，则该带宽资源是第一终端设备的第一带宽资源。该第一带宽资源可以包含预定义的N个随机接入信道机会的资源，N个随机接入信道机会的资源属于第一参数个随机接入信道机会，N是正整数。预定义的N个随机接入信道机会的资源可以是：按照频率资源位置从低往高的资源顺序排序较低的N个随机接入信道机会的资源。具体地，N＝4，第一参数的值可以是8。预定义的N个随机接入信道机会的资源需要包括随机接入前导传输所在的随机接入信道机会的资源。本方案能够节省比特开销，并且能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数。例如，根据随机接入前导传输所在的随机接入信道机会的资源，确定第一带宽资源。第一带宽资源为以随机接入前导传输所在的随机接入信道机会的资源的第一个RB或第一个RB的第一个子载波为起始的资源；或者，根据随机接入前导传输所在的随机接入信道机会的资源，确定第一带宽资源，第一带宽资源为以随机接入前导传输所在的随机接入信道机会的资源的最后一个RB或最后一个RB的最后一个子载波为结束的资源。本方案可能的场景：第一类型终端设备和第二类型终端设备接收相同的系统信息，接收相同的第一参数，且只配置一个带宽资源。
应理解，该场景只是一种示例，本申请对此不做限定。
一种可能的实现方式，第一参数的值大于4时，且M＝1时,该带宽资源是第一终端设备的第一带宽资源，第一终端设备还获取第一指示信息，第一指示信息可以指示第一随机接入信道机会。第一带宽资源的起始资源块与第一随机接入信道机会的起始资源块相同。例如，第一参数的值为8，且第一信息为第一终端设备只配置了1个带宽资源，则该带宽资源是第一终端设备的第一带宽资源。第一带宽资源的起始资源块可以是按照第一指示信息确定的。例如，第一随机接入信道机会是索引为r的随机接入信道机会，r为大于或等 于0的整数。第一带宽资源的起始资源块与第一随机接入信道机会的起始资源块相同，也可以理解为第一带宽资源的起始资源块的频率位置与第一随机接入信道机会的起始资源块的频率位置对齐。例如，N＝4，第一参数的值可以是8。本方案可能的场景：第一类型终端设备和第二类型终端设备接收相同的系统信息，接收相同的第一参数，且只配置一个带宽资源。
示例地，第一指示信息可以包括1个比特，第一指示信息可以在随机接入信道机会索引{0,4}中指示所述第一随机接入信道机会的索引。如果第一指示信息指示为索引0，第一带宽资源可以包含随机接入信道机会索引为{0,1,2,3}的资源。如果第一指示信息指示为索引4，第一带宽资源可以包含随机接入信道机会索引为{4,5,6,7}的资源。例如，根据随机接入前导传输所在的随机接入信道机会的资源，指示第一带宽资源。第一带宽资源为以随机接入前导传输所在的随机接入信道机会的资源的第一个RB或第一个RB的第一个子载波为起始的资源；或者，根据随机接入前导传输所在的随机接入信道机会的资源，确定第一带宽资源，第一带宽资源为以随机接入前导传输所在的随机接入信道机会的资源的最后一个RB或最后一个RB的最后一个子载波为结束的资源。本方案指示的2种可能的第一带宽资源的位置能够包含所有的随机接入信道机会的资源，能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数。
其中，RO的索引如图12所示。
示例地，第一指示信息可以包括2个比特，第一指示信息在随机接入信道机会索引{1,2,3,4}中指示所述第一随机接入信道机会的索引。如果第一指示信息指示为索引1，第一带宽资源可以包含随机接入信道机会索引为{1,2,3,4}的资源。如果第一指示信息指示为索引2，第一带宽资源可以包含随机接入信道机会索引为{2,3,4,5}的资源。如果第一指示信息指示为索引3，第一带宽资源可以包含随机接入信道机会索引为{3,4,5,6}的资源。如果第一指示信息指示为索引4，第一带宽资源可以包含随机接入信道机会索引为{4,5,6,7}的资源。本方案指示的4种可能的第一带宽资源的位置能够包含所有的随机接入信道机会的资源，能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数，并且指示的更加灵活。
示例地，第一指示信息还可以包括3个比特，第一指示信息在随机接入信道机会索引{0,1,2,3,4}中指示第一随机接入信道机会的索引。如果第一指示信指示为索引0，第一带宽资源可以包含随机接入信道机会索引为{0,1,2,3}的资源。如果第一指示信息指示为索引1，第一带宽资源可以包含随机接入信道机会索引为{1,2,3,4}的资源。如果第一指示信息指示为索引2，第一带宽资源可以包含随机接入信道机会索引为{2,3,4,5}的资源。如果第一指示信息指示为索引3，第一带宽资源可以包含随机接入信道机会索引为{3,4,5,6}的资源。如果第一指示信息指示为索引4，第一带宽资源可以包含随机接入信道机会索引为{4,5,6,7}的资源。本方案指示的5种可能的第一带宽资源的位置能够包含所有的随机接入信道机会的资源，能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数，并且指示的更加灵活。
示例地，第一指示信息包括3个比特，第一指示信息还可以在随机接入信道机会索引{0,1,2,3,4,5,6,7}中指示第一随机接入信道机会的索引。如果第一指示信指示为索引0，第一带宽资源可以包含随机接入信道机会索引为{0,1,2,3}的资源。如果第一指示信息指示为 索引1，第一带宽资源可以包含随机接入信道机会索引为{1,2,3,4}的资源。如果第一指示信息指示为索引2，第一带宽资源可以包含随机接入信道机会索引为{2,3,4,5}的资源。如果第一指示信息指示为索引3，第一带宽资源可以包含随机接入信道机会索引为{3,4,5,6}的资源。如果第一指示信息指示为索引4，第一带宽资源可以包含随机接入信道机会索引为{4,5,6,7}的资源。如果第一指示信息指示为索引5，第一带宽资源可以包含随机接入信道机会索引为{5,6,7}的资源。如果第一指示信息指示为索引6，第一带宽资源可以包含随机接入信道机会索引为{6,7}的资源。如果第一指示信息指示为索引7，第一带宽资源可以包含随机接入信道机会索引为{7}的资源。本方案指示的8种可能的第一带宽资源的位置能够包含所有的随机接入信道机会的资源，能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数，并且指示的更加灵活。
示例地，也可以通过第一指示信息的存在与否确定第一随机接入信道机会的索引。第一指示信息不存在也可以理解为，第一终端设备未获取第一指示信息。例如，第一指示信息可以缺省，若第一指示信息缺省，则第一随机接入信道机会是索引为0的随机接入信道机会。本方案可以和前述实施例相互结合。例如，本方案可以和第一指示信息可以包括2个比特一起应用，若第一指示信息缺省，则第一随机接入信道机会是索引为0的随机接入信道机会；若第一指示信息包括2个比特，则第一指示信息在随机接入信道机会索引{1,2,3,4}中指示所述第一随机接入信道机会的索引。
一种可能的实现方式，第一参数的值大于4时，且M>1时,M个带宽资源中的每个带宽资源包含第一参数个随机接入信道机会中的一个或多个随机接入信道机会的资源，第一终端设备在M个带宽资源中确定第一带宽资源。本方案可能的场景：第一类型终端设备和第二类型终端设备接收相同的系统信息，接收相同的第一参数，且配置多个带宽资源。
应理解，该场景只是一种示例，本申请对此不做限定。
可以理解为，M个带宽资源中的不同带宽资源包含的随机接入信道机会的资源不同。例如，第一参数的值为8，且第一信息为第一终端设备配置了2个带宽资源，2个带宽资源中的每个带宽资源包含8个随机接入信道机会中的一个或多个随机接入信道机会的资源，例如，如图13所示，2个带宽资源中的一个带宽资源包含索引为{0,1,2,3}的随机接入信道机会的资源，另一个带宽资源包含索引为{4,5,6,7}的随机接入信道机会的资源。第一终端设备可以在该2个带宽资源中确定第一带宽资源。第一带宽资源可以为索引为{0,1,2,3}的带宽资源第一带宽资源也可以是索引为{4,5,6,7}的带宽资源。第一带宽资源可以根据随机接入前导传输所在的随机接入信道机会的资源来确定。本方案能够节省比特开销，并且能够保证随机接入前导的传输不需要做频率调谐，减少频率调谐次数。
一种可能的实现方式，第一终端设备接收第二指示信息，第二指示信息可以在M个带宽资源中指示第二带宽资源。第二带宽资源可以与所述第一带宽资源不同，即第二带宽资源包含的随机接入信道机会的资源与第一带宽资源包含的随机接入信道机会的资源不完全相同。第二带宽资源也可以与所述第一带宽资源相同，即第二带宽资源包含的随机接入信道机会的资源与第一带宽资源包含的随机接入信道机会的资源相同。
具体地，第二指示信息可以由随机接入响应消息(Random access response，RAR)、调度随机接入响应消息的下行控制信息、竞争解决消息(Msg4)、调度竞争解决消息的下行控制信息中的一种或多种承载，和/或，第二指示信息包含在随机接入响应消息中的 每个媒体接入控制随机接入响应(MAC RAR)的上行授权(UL grant)中。第二指示信息可以为第一类型的终端设备中的每个终端设备指示第二信道带宽，则第二指示信息可以包含在MAC RAR的UL grant中。
第二指示信息可以为第一类型的终端设备中的一组终端设备指示第二信道带宽资源，则第二指示信息可以包含在RAR，调度RAR的DCI，Msg4，调度Msg4的DCI。
第二指示信息可以由两种信息分别承载，例如在调度Msg4的DCI和MAC RAR的UL grant中同时承载，用来指示第一终端设备在第二带宽资源中发送随机接入过程中的消息3，或发送对竞争解决消息反馈的物理上行控制信道。
示例地，第一终端设备在第一带宽资源中发送随机接入前导。第一终端设备在第二带宽资源中发送随机接入过程中的消息3，或发送对竞争解决消息反馈的物理上行控制信道。
第一终端设备发送随机接入前导的带宽资源与发送随机接入过程中的消息3的带宽资源可以不同。第一终端设备发送随机接入前导的带宽资源与发送对竞争解决消息反馈的物理上行控制信道的带宽资源可以不同。第一终端设备发送随机接入前导的带宽资源与发送随机接入过程中的消息3和对竞争解决消息反馈的物理上行控制信道的带宽资源可以不同。第一终端设备发送随机接入过程中的消息3的带宽资源与发送对竞争解决消息反馈的物理上行控制信道的带宽资源可以不同。例如，第五指示信息可以由RAR，调度RAR的DCI，Msg4，调度Msg4的DCI，MAC RAR的UL grant中的一种或多种承载，指示了第三带宽资源，第一终端设备在第二带宽资源中发送随机接入过程中的消息3，第一终端设备在第三带宽资源发送对竞争解决消息反馈的物理上行控制信道，第三带宽资源与第一带宽资源相同或不同，第三带宽资源与第二带宽资源相同或不同。又如，第一终端设备在第一带宽资源中发送随机接入前导，第二指示信息为调度RAR的DCI，指示了第二带宽资源，则第一终端设备在第二带宽资源中发送随机接入过程中的消息3，或发送对竞争解决消息反馈的物理上行控制信道。又如，第一终端设备还可以接收第五指示信息，第五指示信息是调度Msg4的DCI，指示了第三带宽资源，则第一终端设备在第三带宽资源发送对竞争解决消息反馈的物理上行控制信道。
第一终端设备可以在第一带宽资源发送所有上行信息，这样可以保证上行传输过程中不需要做频率调谐，减少频率调谐的次数。第一终端设备也可以在第一带宽资源发送随机接入前导，在第二带宽发送随机接入过程中的消息3和对竞争解决消息反馈的物理上行控制信道，这样可以在减小频率调谐次数的基础上，考虑负载均衡。第一终端设备也可以在第一带宽资源发送随机接入前导，在第二带宽资源发送随机接入过程中的消息3的第一跳传输，在第三带宽资源发送随机接入过程中的消息3的第二跳传输和对竞争解决消息反馈的物理上行控制信道，这样有利于第一终端设备获得随机接入过程中的消息3的频率分集增益。第一终端设备也可以在第一带宽资源发送随机接入前导，在第二带宽资源发送随机接入过程中的消息3和对竞争解决消息反馈的物理上行控制信道的第一跳传输，在第三资源发送对竞争解决消息反馈的物理上行控制信道的第二跳传输，这样有利于物理上行控制信道的频率分集增益，以及解决物理上行控制信道的资源分配导致的资源碎片问题。
示例地，第一终端设备在第一带宽资源中发送随机接入前导，第一终端设备接收第三指示信息。可以根据第三指示信息的比特状态来确定第一终端设备发送信息的资源。第一终端设备只需要检测第三指示信息，就可以确定是否存在第二带宽资源/第三带宽资源， 若不存在则不需要检测配置信息，降低终端设备的复杂度。
比如，第三指示信息的比特状态是第一比特状态，第一终端设备在第一带宽资源中发送随机接入过程中的消息3，和/或在第一带宽资源中发送对竞争解决消息反馈的物理上行控制信道；第三指示信息的比特状态是第二比特状态，第一终端设备在第二带宽资源中发送随机接入过程中的消息3，和/或在第二带宽资源中发送对竞争解决消息反馈的物理上行控制信道。
又如，第三指示信息的比特状态是第二比特状态，第一终端设备在第二带宽资源中发送随机接入过程中的消息3，在第三带宽资源中发送对竞争解决消息反馈的物理上行控制信道。
示例地，第三指示信息可以标识信息，该标识信息可以包含在DCI中，或高层信令中。例如，第三指示信息可以由RAR，调度RAR的DCI，Msg4，调度Msg4的DCI，MAC RAR的UL grant中的一种或多种承载。例如，第三指示信息是调度RAR的DCI，第三指示信息应用该DCI中的可用比特，指示第一终端设备发送信息的资源。
例如，比特状态是第一比特状态时，第一终端设备发送随机接入过程中的消息3，和/或发送对竞争解决消息反馈的物理上行控制信道的带宽资源与发送随机接入前导的第一带宽资源相同。
又如，比特状态是第二比特状态时，第一终端设备发送随机接入过程中的消息3，和/或发送对竞争解决消息反馈的物理上行控制信道的带宽资源与发送随机接入前导的第一带宽资源不同。例如，比特状态是第二比特状态时，第一终端设备发送随机接入过程中的消息3，和/或发送对竞争解决消息反馈的物理上行控制信道的带宽资源与发送随机接入前导的第一带宽资源不同。
一种可能的实现方式，随机接入信道配置信息的应用与第一参数的值有关联。第一参数的值大于4时，随机接入信道配置信息用于所述第一类型的终端设备和用于第二类型的终端设备。第一参数的值小于或等于4时，随机接入信道配置信息只用于第一类型的终端设备。
例如，第一参数的值大于4时，随机接入信道配置信息不能只用于所述第一类型的终端设备。由于第一类型的终端设备支持的最大信道带宽小于第一参数的值大于4对应的随机接入信道机会的资源的大小，因此第一参数的值大于4时，随机接入信道配置信息不能只用于所述第一类型的终端设备，有利于第一类型终端设备和第二类型终端设备,在同一个网络设备覆盖下的共存。
一种可能的实现方式，所述M个带宽资源的配置只用于第一类型的终端设备。例如，M个带宽资源为M个上行BWP或为M个下行BWP。例如，M个带宽资源的配置是为第一类型的终端设备独立配置的。M个带宽资源的配置是为第一类型的终端设备独立配置的，可以理解为，通过独立的字段或独立的参数来配置，该独立的字段或该独立的参数与第二类型的终端设备的字段或参数不同，或该独立的字段或该独立的参数配置的内容与第二类型的终端设备的字段或参数配置的内容不同。
下行信息包括调度SIB1的PDCCH,承载SIB1的PDSCH,调度SI的PDCCH,承载SI的PDSCH,调度Msg2的PDCCH,承载Msg2的PDSCH,调度Msg3的PDCCH,调度Msg4的PDCCH,承载Msg4的PDSCH的一种或多种。
示例地，随机接入信道配置信息用于第一类型的终端设备和用于第二类型的终端设备时，且第一参数的值大于4，第一终端设备在第一带宽资源中发送上行信息或接收下行信息。例如，随机接入信道配置信息是第一类型的终端设备和第二类型的终端设备共同配置的，即不是为第一类型的终端设备独立配置的。例如，第一参数的值为8。
示例地，随机接入信道配置信息用于第一类型的终端设备和用于第二类型的终端设备时，且第一参数的值大于4，第一终端设备在所述第二带宽资源中发送上行信息或接收下行信息。例如，随机接入信道配置信息是第一类型的终端设备和第二类型的终端设备共同配置的，即不是为第一类型的终端设备独立配置的。
示例地，随机接入信道配置信息用于第一类型的终端设备和用于第二类型的终端设备时，且第一参数的值小于等于4，第一终端设备在包含第一参数个随机接入信道机会的带宽资源中发送上行信息或接收下行信息。例如，随机接入信道配置信息是第一类型的终端设备和第二类型的终端设备共同配置的，即不是为第一类型的终端设备独立配置的。例如，第一参数的值为1或2或4。例如，第一参数个随机接入信道机会的带宽资源可以是预定的第一参数个随机接入信道机会的资源，也可以是通过第一指示信息确定的第一带宽资源。
其中，第一带宽资源、第二带宽资源的确定可以参见上述实施例中的方法，在此不再赘述。
示例地，随机接入信道配置信息只用于所述第一类型的终端设备，第一信息指示了第一带宽资源，第一终端设备在第一带宽资源中发送上行信息或接收下行信息。例如，随机接入信道配置信息是为第一类型的终端设备独立配置的。例如，系统信息中配置了第一带宽资源，则第一终端设备在第一带宽资源中发送上行信息或接收下行信息。
一种可能的实现方式，第一终端设备获取指示信息，指示信息用于指示SSB和随机接入的关联配置，第一终端设备根据指示信息确定SSB和随机接入的关联配置。SSB和随机接入的关联配置可以表示一个随机接入信道机会(RO)关联的SSB数。
示例地，关联配置可以是第一关联配置，或关联配置是第二关联配置。例如，第四指示信息的第一比特状态为第一关联配置，第四指示信息的第二比特状态为第二关联配置。例如，第一关联配置为新的SSB和随机接入信道机会的关联配置，即第一关联配置与第二类型的终端设备的SSB和随机接入信道机会的关联配置不同。
示例地，可以根据指示信息的存在与否确定关联配置的类型。
比如指示信息出现，第一终端设备确定SSB和随机接入信道机会的关联配置是第一关联配置；指示信息不出现，第一终端设备确定SSB和随机接入信道机会的关联配置是第二关联配置。例如，指示信息是可选配置的，若配置了指示信息，即指示信息出现，SSB和随机接入信道机会的关联配置是第一关联配置，若没有配置指示信息，即指示信息不出现，SSB和随机接入信道机会的关联配置是第二关联配置。例如，指示信息是标识信息，包含1比特。
应理解，上述指示信息或者指示信息的比特状态与关联配置的对应关系只是一种示例，本申请对此不做限定。
该方案对于FDD系统，或TDD上下行解耦系统来说，通过确定第一资源的频域位置和带宽，能够避免初始接入阶段上行传输之间的RF retuning。
本申请通过确定上行发送的带宽资源或下行接收的带宽资源，从而使两次相邻的上行发送所在的总频率范围，或两次相邻的下行接收所在的总频率范围在终端设备支持的最大信道带宽范围内，来避免频繁的上行发送之间的频率调谐，和/或避免频繁的下行接收之间的频率调谐，进而提升数据传输可用的符号、提升资源利用效率、避免增加UE的功耗和降低UE实现的复杂度。
