具体实施方式
本申请实施例描述的网络架构和业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，随着网络架构的演变和新业务场景的出现，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。
本申请实施例提供的技术方案可能应用于可以分配频率资源的无线通信系统，例如第五代移动通信技术(the fifth generation mobile communication technology，简称5G)系统。本申请实施例提供的技术方案还可能应用于其它基于正交频分复用(orthogonal frequency division multiplexing，简称OFDM)的网络，例如长期演进(long term evolution，简称LTE)系统。本申请实施例中，术语“系统”和“网络”的范围类似。
在无线通信系统中，包括通信设备，通信设备包括网络设备和用户设备(user equipment，简称UE)，通信设备间可以利用空口资源进行无线通信。其中，网络设备还可以称为网络侧设备。通信设备间的无线通信包括：网络设备和UE间的无线通信，网络设备和网络设备间的无线通信。通信设备间利用空口资源进行无线通信时，对空口资源进行管理和/或分配的通信设备还可以称为调度实体，被调度的通信设备还可以称为从属实体。示例性地，当网络设备和UE进行无线通信时，网络设备还可以称为调度实体，UE还可以称为从属实体。本申请实施例可以以网络设备和UE间的无线通信为例，对本申请实施例提供的技术方案进行描述，其中，该技术方案可用于进行调度实体和从属实体间的无线通信。在本申请实施例中，术语“无线通信”还可以简称为“通信”，术语“通信”还可以描述为“数据传输”。
本申请实施例涉及到的UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。本申请实施例中，UE还可以称为终端(terminal)或终端设备(terminal equipment，简称TE)等，本申请不做限定。
本申请实施例涉及到的网络设备包括基站(base station，简称BS)，该网络设备可能为一种部署在无线接入网中可以和UE进行无线通信的设备。其中，基站可能有多种形式，比如宏基站、微基站、中继站和接入点等。当宏基站和微基站通过无线回传的方式进行无线通信时，宏基站还可以称为调度实体，微基站还可以称为从属实体。示例性地，本申请实施例涉及到的基站可以是5G系统中的基站，其中，5G系统中的基站还可以称为发送接收点(transmission Reception Point，简称TRP)或gNB(generation Node B，简称gNB)；本申请实施例涉及到的基站还可以是LTE中的演进型基站(evolved Node B，简称eNB或e-NodeB)。在本申请实施例提供的技术方案中，可 以以基站是5G系统中的gNB为例，以gNB和UE间的无线通信为例，描述本申请实施例提供的技术方案，该技术方案可用于进行调度实体和从属实体间的无线通信。本领域技术人员可以不付出创造性劳动，将本申请实施例提供的技术方案用于进行其它调度实体和从属实体间的无线通信。
在无线通信系统中，gNB和UE可以利用空口资源进行无线通信。空口资源可以包括频率资源，频率资源可以位于设置的频率范围。其中，频率范围还可以称为频带(band)。在频域，频率资源的中心点可以称为中心频点，频域资源的宽度可以称为带宽(bandwidth，简称BW)。示例性地，图1所示为频率资源可能的结构示意图。如图1中所示，频率资源可以为频带内的一段资源，频率资源的带宽为W，中心频点的频率为F，频率资源的边界点的频率分别为F-W/2和F+W/2，还可以描述为，频率资源中最高频点的频率为F+W/2，频率资源中最低频点的频率为F-W/2。
gNB和UE利用系统频率资源进行无线通信时，gNB管理系统频率资源，从系统频率资源中为UE分配频率资源，使得gNB和UE可以利用该分配的频率资源进行通信。其中，系统频率资源是网络设备可以管理和分配的频率资源，在本申请实施例中，系统频率资源还可以简称为系统资源。在频域，系统频率资源的宽度可以称为系统频率资源的带宽，还可以称为系统带宽或传输带宽。在通信系统中，随着UE业务量的增加，尤其是随着UE数量的增加，系统业务量显著增加，因此，现有通信系统中提出了系统带宽为大带宽的设计，用于在系统中提供较高的数据传输速率。在系统带宽为大带宽的系统中，考虑到UE的成本以及UE的业务量，UE支持的带宽可能远小于系统带宽。其中，UE支持的带宽还可以称为UE的带宽能力。UE支持的带宽越大，UE的处理能力越强，UE的数据传输速率可能越高，UE的设计成本可能越高。示例性地，在5G系统中，系统带宽最大可能为400MHz，UE的带宽能力可能为20MHz、50MHz或100MHz等。在无线通信系统中，不同UE的带宽能力可以相同也可以不同，本申请实施例不做限制。
当系统带宽为大带宽时，gNB为UE分配频率资源的一种方法为：首先，gNB通过信令动态地为UE配置该UE的工作带宽资源。其中，为UE配置的工作带宽资源包括于系统频率资源中，其带宽可以小于等于UE支持的带宽。然后，gNB从UE的工作带宽资源中为UE分配频率资源，可以使gNB和UE在该分配的频率资源进行无线通信。
本申请实施例中，带宽资源包括于系统频率资源中，可以是系统频率资源中连续的或者不连续的部分或者全部资源。带宽资源还可以称为带宽部分、频率资源、频率资源部分、部分频率资源或者其它名称，本申请不做限制。当带宽资源为系统频率资源中的一段连续资源时，带宽资源还可以称为子带、窄带或者其它名称，本申请不做限制。在基于OFDM的系统中，可以为一个带宽资源配置相应的参数，该参数包括子载波间隔和循环前缀(cyclic prefix，简称CP)中至少一个。第三代合作伙伴计划(third generation partnership project，简称3GPP)在研究和制定无线通信系统的标准的过程中，该参数的英文名称还可以称为numerology。不同带宽资源的参数的值可以相同，也可以不同，本申请不作限制。
在本申请实施例中，UE的工作带宽资源还可以描述为用于gNB和UE传输UE 特定信息的带宽资源。其中，UE特定信息包括UE特定下行控制信息(downlink control information，简称DCI)、UE特定上行控制信息(uplink control information，简称UCI)、承载于数据信道的UE特定信息和UE特定参考信号中至少一个。其中，gNB和UE传输UE特定信息包括：gNB向UE发送UE特定信息、gNB接收UE发送的UE特定信息、UE接收gNB发送的UE特定信息、和UE向gNB发送UE特定信息中至少一个。例如，UE可以在特定搜索空间从gNB接收PDCCH，接收该PDCCH中携带的DCI。进一步地，UE的工作带宽资源还可以称为工作带宽资源、UE工作带宽资源、带宽资源或者其它名称，本申请不做限制。进一步地，不同UE的工作带宽资源可以相同，也可以不相同，本申请不做限制。示例性地，多个UE可以共享相同的工作带宽资源，也可以为每个UE独立配置工作带宽资源。
如果gNB通过信令动态地为UE配置该UE的工作带宽资源，可能会出现gNB和UE对该UE的工作带宽资源的理解不一致，由此导致gNB接收不到UE发送的数据，UE也接收不到gNB发送的数据，即gNB和UE无法正常地进行数据传输。导致出现gNB和UE对该UE的工作带宽资源理解不一致的场景有如下可能：示例性地，如果gNB通过信令动态地为UE重配置该UE的工作带宽资源，且无需该UE向gNB发送针对该信令的反馈，UE可能会漏检或错检该信令，此时，gNB可能认为该UE的工作带宽资源为UE目标工作带宽资源，UE可能认为该UE的工作带宽资源为UE源工作带宽资源，即gNB和UE可能对该UE的工作带宽资源理解不一致。再示例性地，如果gNB通过信令动态地为UE重配置该UE的工作带宽资源，且UE向gNB发送针对该信令的反馈，gNB可能会漏检或错检该反馈，此时，gNB可能认为该UE的工作带宽资源为UE源工作带宽资源，UE可能认为该UE的工作带宽资源为UE目标工作带宽资源，即gNB和UE可能对该UE的工作带宽资源理解不一致。
本申请实施例中，当gNB为UE重配置该UE的工作带宽资源时，UE源工作带宽资源是重配置前该UE的工作带宽资源，UE源工作带宽资源还可以称为源工作带宽资源、UE的源工作带宽资源、源带宽资源、第一带宽资源或者其它名称，本申请不做限制。进一步地，UE源工作带宽资源可以为一个或者多个带宽资源，还可以理解为，gNB可以为UE配置一个或者多个该UE的工作带宽资源。其中，术语“源”在英文中可能翻译为source。
本申请实施例中，当gNB为UE重配置该UE的工作带宽资源时，UE目标工作带宽资源是gNB为UE重配置的该UE的工作带宽资源。工作带宽资源的重配置生效后，gNB和UE可以将UE目标工作带宽资源作为该UE的工作带宽资源。UE目标工作带宽资源还可以称为目标工作带宽资源、UE的目标工作带宽资源、目标带宽资源、第二带宽资源或者其它名称，本申请不做限制。进一步地，UE目标工作带宽资源可以为一个或者多个带宽资源，还可以理解为，在重配置过程中gNB可以为UE配置一个或者多个该UE的工作带宽资源。其中，术语“目标”在英文中可能翻译为target。
为了解决上述gNB和UE对该UE的UE工作带宽资源的理解不一致的问题，本申请实施例提供了多种技术方案，每种技术方案均涉及相应的方法、装置和系统，以下分别进行举例说明。本申请中装置有时也可以称为通信装置。
第一种技术方案：
在本申请实施例提供的第一种技术方案中，引入了UE校准带宽资源，用于gNB向UE发送UE目标工作带宽资源的信息。具体地：在UE源工作带宽资源，gNB与UE进行UE的第一UE特定信息的传输。在UE的UE校准带宽资源，gNB向UE发送UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于gNB与UE进行UE的第二UE特定信息的传输。其中，UE源工作带宽资源和UE校准带宽资源不完全相同。通过本申请实施例提供的第一种技术方案，UE可以在校准带宽资源接收gNB为UE配置的UE目标工作带宽资源的信息，可以使UE对该UE的工作带宽资源的配置进行校准。因此，可以减少出现gNB和UE对该UE的工作带宽资源理解不一致的概率；或者，当gNB和UE对该UE的工作带宽资源理解不一致时可以进行相应的校准，可以使gNB和UE对UE的工作带宽资源理解一致。
本申请实施例提供的第一种技术方案中，UE校准带宽资源和UE源工作带宽资源不完全相同，用于gNB向UE发送UE目标工作带宽资源的信息。UE校准带宽资源还可以称为校准带宽资源、配置带宽资源、UE配置带宽资源、第三带宽资源或者其它名称，本申请不做限制。作为一种实现的可能，UE校准带宽资源可以为用于gNB向UE发送同步信号和/或广播信道的带宽资源，该带宽资源可以为多个UE共享的带宽资源，在该场景下，UE校准带宽资源还可以称为公共带宽资源或者其它名称，本申请不做限制。作为另一种实现的可能，UE校准带宽资源可以为用于UE初始接入gNB的带宽资源，该带宽资源可以为多个UE共享的带宽资源，在该场景下，UE校准带宽资源还可以称为接入带宽资源、初始接入带宽资源或者其它名称，本申请不做限制。其中，用于gNB向UE发送同步信号和/或广播信道的带宽资源和用于UE初始接入gNB的带宽资源可以为相同或不同的带宽资源，本申请不做限制。
在本申请实施例提供的第一种技术方案中，在UE校准带宽资源，gNB可以周期性地向UE发送UE目标工作带宽资源的信息。该方法中，在UE校准带宽资源，UE可以周期性地接收UE目标工作带宽资源的信息，即UE可以周期性地对UE工作带宽资源的配置进行校准；UE也可以判断其是否需要进行校准，如果需要校准，UE可以接收UE目标工作带宽资源的信息。
在本申请实施例提供的第一种技术方案中，在UE校准带宽资源，gNB还可以基于接收到的UE发送的第一请求，向UE发送UE目标工作带宽资源的信息。其中，第一请求用于请求gNB向UE发送UE目标工作带宽资源的信息。
进一步地，在本申请实施例提供的第一种技术方案中，gNB还可以在UE的工作带宽资源向该UE发送UE目标工作带宽资源的信息。
第二种技术方案：
本申请实施例提供的第二种技术方案中，引入了工作带宽资源回退机制(以下简称“回退机制”)。
本申请实施例提供的第二种技术方案中，可以在gNB侧引入回退机制。在UE源工作带宽资源，gNB与该UE进行该UE的第一UE特定信息的传输。在UE源工作带宽资源，gNB还向UE发送UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于gNB与UE进行该UE的第二UE特定信息的传输。如果gNB没有收到反馈， gNB将UE的UE源工作带宽资源作为UE的工作带宽资源，其中，该反馈为对应于携带UE目标工作带宽资源的信息的信道的反馈。该方法中，如果gNB没有收到反馈，说明UE可能未接收到或者未正确接收到UE目标工作带宽资源的信息，UE可能依然将UE源工作带宽资源作为UE的工作带宽资源，因此，gNB回退至UE源工作带宽资源，gNB将UE源工作带宽资源作为UE的工作带宽资源，可以保证UE和gNB对UE的工作带宽资源的理解一致。
本申请实施例提供的第二种技术方案中，可以在UE侧引入回退机制。在UE源工作带宽资源，UE与gNB进行该UE的第一UE特定信息的传输。在UE源工作带宽资源，UE还接收gNB向UE发送的UE目标工作带宽资源的信息，将UE目标工作带宽资源作为该UE的工作带宽资源。其中，UE目标工作带宽资源用于gNB与UE进行UE的第二UE特定信息的传输。UE向gNB发送反馈，其中，该反馈为对应于携带UE目标工作带宽资源的信息的信道的反馈。在UE目标工作带宽资源，如果UE没有收到gNB发送的第二UE特定信息，UE将UE源工作带宽资源作为UE的工作带宽资源；或者，UE向gNB发送第二请求，在UE目标工作带宽资源，如果UE没有收到gNB发送的第一响应，UE将UE源工作带宽资源作为UE的工作带宽资源。该方法中，如果UE没有收到第二UE特定信息或者没有收到第一响应，说明gNB可能未接收到或者未正确接收到UE发送的反馈，gNB可能依然将UE源工作带宽资源作为UE的工作带宽资源，因此，UE回退至UE源工作带宽资源，UE将UE源工作带宽资源作为UE的工作带宽资源，可以保证UE和gNB对UE的工作带宽资源的理解一致。
在本申请实施例提供的第一种技术方案和第二种技术方案中，gNB向UE发送的UE目标工作带宽资源的信息可能为以下两种信息中的任何一种。
第一种信息：gNB向UE发送的UE目标工作带宽资源的信息可以指示UE目标工作带宽资源为UE候选工作带宽资源中的至少一个带宽资源，或者可以指示UE目标工作带宽资源为包括UE候选工作带宽资源和UE校准带宽资源的集合中的至少一个带宽资源。其中，可以通过预配置的方式为gNB和UE配置UE候选工作带宽资源中至少一个带宽资源的资源位置信息，还可以通过gNB向UE发送信息的方式为UE配置UE候选工作带宽资源中至少一个带宽资源的资源位置信息。
第二种信息：gNB向UE发送的UE目标工作带宽资源的信息包括UE目标工作带宽资源的频率资源位置信息。
第三种技术方案：
本申请实施例提供的第三种技术方案中，引入了一种接入机制。在UE的工作带宽资源，如果UE判断其和gNB对该UE的工作带宽资源理解可能不一致，UE接入gNB。该方法中，通过UE接入gNB，可以恢复UE和gNB的正常通信。
基于上述描述的本申请实施例提供的三种技术方案，下面结合附图，进一步详细 地描述该三种技术方案涉及的方法、装置和系统。
图2所示为本申请实施例提供的第一种带宽资源配置方法，该方法对应于本申请实施例提供的第一种技术方案。
步骤201，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤202，在UE的UE校准带宽资源，gNB向UE发送UE目标工作带宽资源的信息，UE接收gNB发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于gNB与UE进行该UE的第二UE特定信息的传输。其中，UE源工作带宽资源和UE校准带宽资源不完全相同。
gNB通过信令为UE发送该UE的UE目标工作带宽资源的信息，该信令为动态信令，可能由物理下行控制信道(physical downlink control channel，简称PDCCH)携带。gNB发送PDCCH时，PDCCH携带的信息的循环冗余码(cyclic redundancy code，简称CRC)可能被使用相应的无线网络临时标识(radio network temporary identifier,简称RNTI)加扰，用于进行PDCCH的传输的错误检测。UE接收PDCCH，根据上述相应的RNTI对控制信道进行解码，获得PDCCH携带的信息。如果gNB向UE发送的UE目标工作带宽资源的信息为UE特定信息，UE目标工作带宽资源的信息由PDCCH携带，则，gNB可以使用UE特定的RNTI对PDCCH携带的信息的CRC进行加扰。其中，UE特定的RNTI可以为小区RNTI(cell RNTI，简称C-RNTI)。如果gNB向UE发送的UE目标工作带宽资源的信息为多个UE共享的信息，UE目标工作带宽资源的信息由PDCCH携带，则，gNB可以使用公共RNTI对PDCCH携带的信息的CRC进行加扰。其中，该多个UE可能为小区中的全部或者部分UE。
本申请实施例中，信令包括半静态信令和动态信令。半静态信令可以包括无线资源控制(radio resource control，简称RRC)信令、广播消息、系统消息和媒体接入控制(medium access control，简称MAC)控制元素(control element，简称CE)中至少一个，动态信令可以包括物理下行控制信道携带的信令和物理下行数据信道携带的信令中至少一个。其中，物理下行控制信道携带的信令可以称为下行控制信息(downlink control information，简称DCI)。
UE源工作带宽资源和UE校准带宽资源不完全相同还可以描述为：UE源工作带宽资源包括的部分频率资源或全部频率资源不包括在UE校准带宽资源中，或者UE校准带宽资源包括的部分频率资源或全部频率资源不包括在UE源工作带宽资源中。示例性地，在基于OFDM的通信系统中，UE源工作带宽资源和UE校准带宽资源不完全相同可能为：UE源工作带宽资源包括的至少一个子载波不包括在UE校准带宽资源中，或者UE校准带宽资源包括的至少一个子载波不包括在UE源工作带宽资源中。
gNB和UE可以通过预配置的方式确定UE校准带宽资源的频率资源位置信息。gNB还可以通过信令配置的方式为UE配置UE校准带宽资源。gNB向UE发送信令，该信令中指示了UE校准带宽资源的频率资源位置信息。相应地，UE接收gNB发送的该信令，用于确定UE校准带宽资源的频率资源位置信息。对于一个带宽资源，例如UE校准带宽资源，该带宽资源的频率资源位置信息可以为以下第一种频率资源位 置信息至第五种频率资源位置信息中的任一种频率资源位置信息。
第一种频率资源位置信息，包括比特图(bitmap)，用于配置带宽资源包括系统带宽中的哪些资源块(resource block，简称RB)或者哪些资源块组(resource block group，简称RBG)。本申请实施例中，RB和RBG为基于OFDM的通信系统中的资源单位。在基于OFDM的通信系统中，在频域，系统资源中包括若干个资源格，一个资源格对应于一个子载波，一个RB包括C1个资源格，C1为大于1的整数，示例性地，C1为12。系统带宽可以被描述为C2个RB，C2为大于等于1的整数。进一步地，在时域，一个RB可以包括C3个符号，C3为大于1的整数，示例性地，C3为7或14。以一个RB频域包括12个资源格时域包括7个符号为例，图3所示为系统带宽可能的结构示意图，如图3中所示，系统带宽中包括RB 0至RB C2-1共C2个RB。在频域，系统带宽还可以被描述为C4个RBG，一个RBG包括C5个RB，C4和C5为大于1的整数。使用第一种频率资源位置信息，可以通过比特图中各比特的取值，任意地选择包含在带宽资源中的RB或者RBG，因此可以提供灵活的资源配置，可以适用于连续的和非连续的资源分配。
第二种频率资源位置信息，包括参考RB的索引，和连续地分配的RB的个数。其中，参考RB可以是带宽资源中的任意RB，连续地分配的RB的个数是带宽资源的宽度。示例性地，参考RB可以是带宽资源中频率最高的RB、带宽资源中频率最低的RB、或者带宽资源的中心RB。使用第二种频率资源位置信息，可以通过对参考RB索引的指示信息和连续分配RB个数的指示信息进行联合编码，因此，可以用较少的信息位进行资源分配，能够降低资源分配时的信令开销。
第三种资源配置信息，包括参考RBG的索引，和连续地分配的RBG的个数。其中，参考RBG可以是带宽资源中的任意RBG，连续地分配的RBG的个数是带宽资源的宽度。示例性地，参考RBG可以是带宽资源中频率最高的RBG、带宽资源中频率最低的RBG、或者带宽资源的中心RBG。使用第三种频率资源位置信息，可以通过对参考RBG索引的指示信息和连续分配RBG个数的指示信息进行联合编码，因此，可以用较少的信息位进行资源分配，能够降低资源分配时的信令开销。
第四种频率资源位置信息，包括S个组合索引，S为大于等于1的整数。一个组合索引指示P组资源配置信息。P组资源配置信息中的任一组资源配置信息包括一个起始RB索引和一个结束RB索引，或者包括一个起始RBG索引和一个结束RBG索引。其中，P为大于等于1的整数，索引也可以称为标识。一组资源配置信息指示一段连续资源，如果该组资源配置信息包括一个起始RB索引和一个结束RB索引，起始RB索引和结束RB索引相同，则该组资源配置信息指示了一个RB，该RB对应的索引为该起始RB索引或该结束RB索引。如果该组资源配置信息包括一个起始RBG索引和一个结束RBG索引，起始RBG索引和结束RBG索引相同，则该组资源配置信息指示了一个RBG，该RBG对应的索引为该起始RBG索引或结束RBG索引。一个组合索引指示的P组资源配置信息中的各资源配置信息指示的资源之和为该组合索引指示的资源。上述S个组合索引指示的资源之和为带宽资源对应的资源。使用第四种频率资源位置信息，可以通过对起始RB索引的指示信息和结束RB索引的指示信息进行联合编码，因此，可以用较少的信息为进行资源分配，可以降低信令开销。第四 种频率资源位置信息可以支持连续和非连续的资源配置，可以灵活地进行资源配置。
第五种频率资源位置信息，包括子带指示，用于指示带宽资源为系统带宽中的至少一个子带。其中，系统带宽包括至少一个子带。图4所示为系统带宽包括的子带的可能的结构示意图，如图4中所示，系统带宽包括子带0、子带1和子带2共3个子带，一个子带包括系统带宽中的部分带宽。需要说明的是，系统带宽可以包括任意数量的子带，图4中仅示出了其中一种可能。系统带宽包括的不同子带的带宽可以相同也可以不同，本申请实施例不作限制。使用第五种资源配置信息，当分配给UE的带宽频率的带宽大小固定且为连续资源时，可以有效地降低信令开销。
本申请实施例中，频率资源位置信息用于指示资源在频率的位置，其还可以称为频率资源位置配置、频率资源配置信息或者其它名称，本申请不做限制。
在第一种带宽资源配置方法中，gNB向UE发送的UE目标工作带宽资源的信息可以为以下第一种和第二种目标工作带宽资源的信息中至少一种。
第一种目标工作带宽资源的信息：
在第一种带宽资源配置方法中，gNB向UE发送的UE目标工作带宽资源的信息可以指示UE目标工作带宽资源为UE候选工作带宽资源中的至少一个带宽资源，或者可以指示UE目标工作带宽资源为包括UE候选工作带宽资源和UE校准带宽资源的集合中的至少一个带宽资源。此时，第一种带宽资源配置方法还包括：gNB向UE发送UE候选工作带宽资源的频率资源位置信息，UE目标工作带宽资源是UE候选工作带宽资源的子集，UE目标工作带宽资源的信息指示了UE目标工作带宽资源为UE候选工作带宽资源中的至少一个带宽资源。其中，UE候选工作带宽资源可能包括UE校准频率资源。或者，gNB向UE发送UE候选工作带宽资源的频率资源位置信息，UE目标工作带宽资源是包括UE候选工作带宽资源和UE校准带宽资源的集合的子集，UE目标工作带宽资源的信息指示了UE目标工作带宽资源为包括UE候选工作带宽资源和UE校准带宽资源的集合中的至少一个带宽资源。其中，UE候选工作带宽资源不包括UE校准频率资源，UE校准频率资源可能为信令配置的或者预配置的频率资源。UE接收gNB发送的UE候选工作带宽资源的频率资源位置信息。
本申请实施例中，UE候选工作带宽资源还可以描述为UE可选工作带宽资源、UE可能的工作带宽资源、M1个可以用作UE工作带宽资源的带宽资源或者其它名称，本申请不做限制。其中，M1为大于等于1的整数。进一步地，如上述描述，UE候选工作带宽资源还可能包括UE校准带宽资源。UE源工作带宽资源可以为UE候选工作带宽资源中至少一个带宽资源。图5所示为UE候选工作带宽资源的示意图。图5的示例中，系统带宽为400MHz，UE支持的带宽20MHz，UE候选工作带宽资源中的一个带宽资源的带宽为20MHz，UE校准带宽资源为20MHz。系统资源中包括20个带宽资源，各带宽资源无交叠，其中，1个为UE校准带宽资源，另外19个带宽资源为UE候选工作带宽资源；或者该20个带宽资源为UE候选工作带宽资源，其中1个为UE校准带宽资源。UE源工作带宽资源为19个带宽资源中的至少一个带宽资源，该19个带宽资源为系统资源中包括20个带宽资源减去UE校准带宽资源后得到的19个带宽资源。UE目标带宽资源为UE候选工作带宽资源中至少一个带宽资源。图5中所示 各带宽资源无交叠，带宽资源为连续的资源，实际应用中，各带宽资源可以交叠，带宽资源可以为连续的或者不连续的资源，本申请不做限制。
gNB向UE发送UE候选工作带宽资源的频率资源位置信息时，对于候选工作带宽资源中的一个带宽资源，该带宽资源的频率资源位置信息可以为上述第一种频率资源位置信息至第五种频率资源位置信息中的任一种频率资源位置信息。进一步地，gNB向UE发送UE候选工作带宽资源的频率资源位置信息时，可以通过相同的信令发送候选工作带宽资源中的不同带宽资源的频率资源位置信息，也可以通过不同的信令发送候选工作带宽资源中的不同带宽资源的频率资源位置信息，本申请不做限制。
当gNB通过信令配置的方式为UE配置UE校准带宽资源时，即gNB向UE发送UE校准带宽资源的频率资源位置信息时，该信令可以和gNB向UE发送UE候选工作带宽资源的频率资源位置信息时使用的信令相同，也可以不相同。本申请不做限制。当gNB为UE配置UE校准带宽资源时使用的信令和gNB向UE发送UE候选工作带宽资源的频率资源位置信息时使用的信令相同时，该信令中可以包括标志信息，用于指示哪个频率资源为UE校准带宽资源。
在第一种目标工作带宽资源的信息中，为了简化描述，还可以描述为UE目标工作带宽资源的信息指示了UE目标工作带宽资源为M2个带宽资源中的至少一个带宽资源。其中，当UE目标工作带宽资源的信息指示了UE目标工作带宽资源为UE候选工作带宽资源中的至少一个带宽资源时，M2等于UE候选工作带宽资源包括的带宽资源的个数，UE候选工作带宽资源包括的带宽资源还可以描述为M2个带宽资源；当UE目标工作带宽资源的信息指示了UE目标工作带宽资源为包括UE候选工作带宽资源和UE校准带宽资源的集合中的至少一个带宽资源时，M2等于包括UE候选工作带宽资源和UE校准带宽资源的集合中包括的带宽资源的个数，包括UE候选工作带宽资源和UE校准带宽资源的集合还可以描述为M2个带宽资源。在第一种目标工作带宽资源的信息中，UE目标工作带宽资源的信息可以为以下第一种指示信息至第三种指示信息中的任一种指示信息中，用于指示UE目标工作带宽资源为M2个带宽资源中的至少一个带宽资源。其中，M2为大于1的整数。
第一种指示信息，包括K1＝M2个信息位，该K1个信息位和上述M2个带宽资源一一对应。当一个信息位取值为t1时，认为UE目标带宽资源包括该信息位对应的带宽资源，当一个信息位取值为t2时，认为UE目标带宽资源不包括该信息位对应的带宽资源。其中，t1和t2为整数。示例性地，t1为1，t2为0。利用第一种指示信息，可以通过比特图中各比特取值的改变，可以灵活地进行资源配置，可以灵活地指示UE目标带宽资源为M2个带宽资源中的至少一个带宽资源。

其中，K1同第一种指示信息中的K1。如果该K2个信息位的值为K2_X，认为UE目标带宽资源为上述M2个带宽资源中的第K2_X个带宽资源。其中，当K2_X从0开始计数时，K2_X为大于等于0且小于K1的整数；当K2_X从1开始计数时，K2_X为大于等于1且小于等于K1的整数。示例性地，如果M2＝8，则K2＝3，当K2_X值为1时，UE目标带宽资源为上述M2个带宽资源中的第1个带宽资源。如果利用第二种指示信息，可以灵活地指示UE目标带宽资源为M2个带宽资源中的任一个带宽资源，还可以通过二进制编码 降低指示信息的信令开销。
第三种指示信息，包括K3个信息位，K3为整数。通过预配置的方法，配置K3_X对应于至少一个带宽资源，其中，K3_X为K3个信息位可能的取值，该至少一个带宽资源包括于上述M2个带宽资源中。如果K3个信息位的值为K3_X，认为K3_X对应的带宽资源为UE目标带宽资源。示例性地，表1所示为K3_X和带宽资源的可能对应关系。其中，表1中以M2＝8，K3＝1为例。K3_X可能为0或1，当K3_X为0时，认为其对应的带宽资源0、带宽资源1、带宽资源2和带宽资源3为UE目标带宽资源；当K3_X为1时，认为其对应的带宽资源4、带宽资源5、带宽资源6和带宽资源7为UE目标带宽资源。在本申请实施例中，认为带宽资源为UE目标带宽资源，还可以描述为：可以将该带宽资源作为UE目标带宽资源。表1中仅给出一个可能的示例，实际应用中，K3_X和带宽资源的对应关系可能为其它任意关系，本申请不做限制。利用第三种指示信息，可以灵活地指示UE目标带宽资源为M2个带宽资源中的任一个带宽资源，还可以通过二进制编码降低指示信息的信令开销。

通过第一种目标工作带宽资源的信息，可以通过较少的信息位为UE配置UE目标工作带宽资源，指示UE目标工作带宽资源为多个带宽资源中的至少一个带宽资源。
第二种目标工作带宽资源的信息：
在第一种带宽资源配置方法中，gNB向UE发送的UE目标工作带宽资源的信息包括UE目标工作带宽资源的频率资源位置信息。其中，对于UE目标工作带宽资源中的一个带宽资源，该带宽资源的频率资源位置信息可以为上述第一种频率资源位置信息至第五种频率资源位置信息中的任一种频率资源位置信息。通过第二种目标工作带宽资源的信息，可以灵活地将系统资源中的资源配置为UE目标工作带宽资源。为UE灵活地配置资源，用于进行gNB和UE间的通信，可以带来以下三个好处：
第一个好处，在系统资源中为UE配置信道质量较好的资源，提高gNB和UE间的数据传输速率。
第二个好处，可以灵活地为UE配置参数，该参数包括子载波间隔和CP，用于满足UE的业务的服务质量(quality of service，简称QoS)要求。其中，服务质量包括时延和/或误块率(block error rate，简称BLER)。在无线通信系统中，例如5G系统中，为了支持服务质量要求不同的多种业务类型，不同UE或者同一个UE的不同业务类型的数据传输可以使用不同的参数。
第三个好处，提供了一种前向兼容的通信系统。网络设备为UE灵活地配置工作带宽资源，可以使网络设备在系统资源中灵活地配置空白资源，在该空白资源中可以引入各种可能的通信系统，从而实现在系统资源中灵活地进行通信系统的演进。进一 步地，如果系统资源中需要支持多种通信系统，通过灵活地配置空白资源，可以在空白资源中根据该多种通信系统中的各通信系统的负载灵活地配置各通信系统的资源，可以在系统资源中提高该多种通信系统的总的数据传输速率。
本领域技术人员可以理解，本申请实施例的提供三个技术方案中，以及该三个技术方案涉及的方法中，可以灵活地配置资源的方法都有可能有以上三个好处。
通过本申请实施例提供的第一种带宽资源配置方法，UE可以在校准带宽资源接收gNB为UE配置的UE目标工作带宽资源的信息，可以使UE对UE工作带宽资源的配置进行校准。因此，可以减少出现gNB和UE对UE的工作带宽资源理解不一致的概率，或者当gNB和UE对UE的工作带宽资源理解不一致时可以进行相应的校准，从而可以使gNB和UE对UE的工作带宽资源理解一致。
下面结合图6，详细说明本申请实施例提供的第二种带宽资源配置方法，该方法对应于方法对应于本申请实施例提供的第一种技术方案中gNB周期性地向UE发送UE目标工作带宽资源的信息。
步骤601，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤602，在第一周期，在UE的UE校准带宽资源，gNB向UE发送UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于gNB与UE进行UE的第二UE特定信息的传输，UE源工作带宽资源和UE校准带宽资源不完全相同，第一周期包括整数个第一时间单元。
步骤602可以包括步骤202。
gNB可以基于第一周期，周期性地为UE发送UE目标工作带宽资源的信息。其中，第一周期包括整数个第一时间单元，还可以描述为第一周期包括N1第一个时间单元，N1为大于1的整数。在一个第一周期，在该第一周期中的N2个第一时间单元，在UE的UE校准带宽资源，gNB可以向UE发送UE目标工作带宽资源的信息。其中，N2为小于等于N1的整数。
gNB和UE可以根据预配置确定第一周期。gNB还可以向UE发送信令，该信令中包括第一周期的配置。相应地，UE接收gNB发送的信令。UE根据接收到的信令，确定第一周期。预配置或者信令配置第一周期时，可以配置第一周期为整数个时间单元，示例性地，该时间单元为第一时间单元；也可以配置第一周期为具体的时间长度，该时间长度的单位为秒或者毫秒等常用的时间单位。本申请实施例中，时间单元还可以称为时间单位，包括符号、时隙、微时隙、子帧、无线帧等通信系统领域常用的时间单元。当通信系统中支持多种参数时，由于不同参数对应的时间单元长度不同，因此，当配置第一周期为整数个第一时间单元时，还可以配置第一时间单元对应的参数，其中，参数包括子载波间隔和CP中至少一个。示例性地，可以配置第一时间单元对应的子载波间隔和UE工作带宽资源对应的子载波间隔相同；还可以配置第一时间单元对应的子载波间隔为参考子载波间隔，参考子载波间隔为根据载波频域预配置的子载波间隔；还可以通过gNB向UE发送的信令为UE配置第一时间单元对应的子载波间隔。
gNB和UE可以根据预配置确定第一周期中的N2个第一时间单元。gNB还可以向UE发送信令，信令中包括第一周期中的N2个第一时间单元的配置。相应地，UE接收gNB发送的信令。UE根据接收到的信令，确定第一周期中的N2个第一时间单元。配置第一周期中的N2个第一时间单元时，可以通过以下第一种配置信息至第三种配置信息中的任一种进行相应的配置：
第一种配置信息，包括偏移量P1和步长P2。第一周期中的N2个第一时间单元中的第一个时间单元为第一周期中第P1个第一时间单元，第一周期中的N2个第一时间单元中的两个相邻第一时间单元的距离为P2个第一时间单元。其中，P1和P2为整数。利用第一种配置信息，可以通过偏移量P1和步长利用较少的信息位指示第一周期中的N2个第一时间单元，适用于等间隔配置。本领域技术人员可以理解，当N2＝1时，第一种配置信息中还可以不包括步长P2。
第二种配置信息，包括P3个信息位，P3等于第一周期包括的第一时间单元的个数，即P1等于上述N1。该P3个信息位和第一周期包括的第一时间单元一一对应。当一个信息位取值为t1时，认为该信息位对应的第一时间单元包括于本步骤中描述的第一周期中的N2个第一时间单元中；当一个信息位取值为t2时，认为该信息位对应的第一时间单元不包括于本步骤中描述的第一周期中的N2个第一时间单元中中。其中，t1和t2为整数。示例性地，t1为1，t2为0。利用第二种配置信息，可以通过各信息位取值的改变，灵活地配置第一周期中至少一个第一时间单元可用于传输UE目标工作带宽资源的信息，适用于时域内连续和非连续的配置。
第三种配置信息，包括数值N2。第一周期内的任意N2个第一时间单元为本步骤中描述的第一周期中的N2个第一时间单元。在TDD系统中，gNB可以根据业务量等参数配置上下行配置，上下行配置用于配置时间单元是用于下行(downlink，简称DL)传输还是上行(uplink，简称UL)传输。利用第三种配置信息，可以使gNB基于其上下行配置，灵活地选择第一时间单元，在该选择的第一时间单元向UE发送UE目标工作带宽资源的信息。
进一步地，在一个第一周期中，或者在一个第一周期中的N2个第一时间单元中的一个或者多个第一时间单元，如果gNB不需要为UE重配置工作带宽资源，gNB可以不向UE发送UE目标工作带宽资源的信息，以节省信令开销。
在本申请实施例中，gNB在第一周期，或者在第一周期中的N2个第一时间单元中的一个或者多个第一时间单元向UE发送UE目标工作带宽资源的信息，该信息可以由物理信道A携带，示例性地，物理信道A为PDCCH。还可以描述为，gNB在第一周期，或者在第一周期中的N2个第一时间单元中的一个或者多个第一时间单元向UE发送物理信道A，物理信道A中携带UE目标工作带宽资源的信息。在本申请实施例中，gNB向UE发送物理信道，还可以描述为gNB向UE发送该物理信道携带的信息。
在第一周期，在UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于gNB与UE进行UE的第二UE特定信息的传输；UE源工作带宽资源和UE校准带宽资源不完全相同；第一周期包括 整数个第一时间单元。UE可以利用以下第一种接收方法，周期性地接收UE目标工作带宽资源的信息；UE也可以利用以下第二种接收方法，UE基于判断是否需要校准UE工作带宽资源，接收UE目标工作带宽资源的信息。
第一种接收方法，UE周期性地接收UE目标工作带宽资源的信息。在一个第一周期，在该第一周期，在第一周期中的N2个第一时间单元，在该UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息。其中，第一周期中的N2个第一时间单元同上述描述，这里不再赘述。
图7所示为UE在UE校准带宽资源接收gNB发送的UE目标工作带宽资源的信息的一个示意图。如图7中所示，配置第一周期，配置第一周期中一个第一时间单位A，用于传输UE目标工作带宽资源的信息，即N2＝1。gNB在第一周期的第一时间单元A，在UE的UE校准带宽资源，向该UE发送UE目标工作带宽资源的信息。图7中示例N2＝1，实际中N2可以为任意大于等于1小于等于上述N1的整数。如图7中所示，在第一个第一周期，UE在接收UE目标工作带宽资源的信息之前，UE的工作带宽资源为带宽资源A。UE在第一个第一周期的第一时间单元A，在UE的UE校准带宽资源，接收gNB发送的UE目标工作带宽资源的信息，该信息可以指示UE目标工作带宽资源为带宽资源A，UE依然将带宽资源A作为UE的工作带宽资源，还可以描述为，UE不更新该UE的工作带宽资源。在第二个第一周期，UE在接收UE目标工作带宽资源的信息之前，UE的工作带宽资源为带宽资源A。UE在第二个第一周期的第一时间单元A，在UE的UE校准带宽资源，接收gNB发送的UE目标工作带宽资源的信息，该信息可以指示UE目标工作带宽资源为带宽资源B，UE将带宽资源B作为UE的工作带宽资源，即UE更新了UE的工作带宽资源，还可以描述将UE的工作带宽资源进行了校准。
第二种接收方法，UE基于判断是否需要校准UE工作带宽资源，接收UE目标工作带宽资源的信息。在UE源工作带宽资源，如果UE接收到gNB发送的该UE的第一UE特定信息，UE启动或重新启动第一定时器。其中，UE重新启动第一定时器可能为，在UE源工作带宽资源，如果UE接收到gNB发送的该UE的第一UE特定信息，且第一定时器为运行状态，则，UE重新启动第一定时器。第一定时器期满之后，在UE的UE校准带宽资源，接收gNB发送的UE目标工作带宽资源的信息。示例性地，如果第一定时器期满，在定时器期满后的第一时间单元，在UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息。其中，该第一时间单元可以为一个或者多个第一时间单元，该第一时间单元包括于一个或多个第一周期中，为第一周期中的N2个第一时间单元中的第一时间单元。在一种实现方式中，如果第一定时器期满，UE从源工作带宽资源切换至UE校准带宽资源，在UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息。第二种接收方法中，如果UE在接收UE目标工作带宽资源的信息时，需要从UE源工作带宽资源切换至UE校准带宽资源，和/或需要从UE校准带宽资源切换至UE目标工作带宽资源，通过该方法可以减少UE在不同带宽资源之间的切换，从而可以减少引入切换时间，为UE节省时域空口资源，提高数据传输速率。其中，UE在接收UE目标工作带宽资源的信息时，需要从UE源工作带宽资源切换至UE校准带宽资源的可能的场景为：UE的带 宽能力不足以同时支持UE源工作带宽资源和UE校准带宽资源。UE在接收UE目标工作带宽资源的信息时，需要从UE校准带宽资源切换至UE目标工作带宽资源的可能的场景为：UE的带宽能力不足以同时支持UE校准带宽资源和UE目标工作带宽资源。
本申请实施例中，UE的带宽能力不足以同时支持X个带宽资源可以描述为：UE的带宽能力为W，该X个带宽资源的最高频点的频率组成的集合为H i,i＝1,2...X，该X个带宽资源的最低频点的频率组成的集合为L i,i＝1,2...X，W<(h-l)，其中，h＝max(H i,i＝1,2...X)，l＝min(L i,i＝1,2...X)。
在本申请实施例提供的任一种方法中，当UE从带宽资源C切换至带宽资源D时，可以为UE配置保护周期(guard period)，用于UE用于从带宽资源C切换至带宽资源D。其中，保护周期用于UE从一个带宽资源切换至另一个带宽资源，还可以称为切换时间，保护时间或者其它名称，本申请不做限制。其中，切换还可以称为调整或者其它名称，本申请不做限制，其英文翻译可能为retune。其中，保护周期可以配置为整数个时间单元；还可以配置具体的时间长度，该时间长度的单位为秒、毫秒、微秒等常用的时间单位。在UE的保护周期，gNB可能不和UE进行通信。
示例性地，在第一周期，在UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息之前，在第一保护周期，UE可能从UE源工作带宽资源切换至UE校准带宽资源。再示例性地，在UE的UE校准带宽资源，UE接收gNB向UE发送的UE目标工作带宽资源的信息之后，在第二保护周期，UE从UE校准带宽资源切换至UE目标工作带宽资源。示例性地，如上述描述，图7所示为UE在UE校准带宽资源接收gNB发送的UE目标工作带宽资源的信息的一个示意图。在图7中，UE在第一时间单元A之前，在第一保护周期，从UE源工作带宽资源切换至UE校准带宽资源；UE在第一时间单元A之后，在第二保护周期，从UE校准带宽资源切换至UE目标工作带宽资源。其中，第一保护周期和第二保护周期可以相同，也可以不相同，本申请不做限制。
通过本申请实施例提供的第二种带宽资源配置方法，通过第一周期，可以在时域内相对固定地进行UE目标工作带宽资源的信息的传输，可以使得UE在时域内有针对性地进行UE目标工作带宽资源的信息的接收，从而可以提高了UE接收UE目标工作带宽资源的信息的鲁棒性，进一步地，还可能节省UE的功率。
下面结合图8，详细说明本申请实施例提供的第三种带宽资源配置方法，该方法对应于本申请实施例提供的第一种技术方案中，gNB基于UE请求，向UE发送UE目标工作带宽资源的信息。
步骤801，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤802，UE向gNB发送第一请求，第一请求用于请求gNB向该UE发送UE目标工作带宽资源的信息。
gNB接收UE发送的第一请求。
可选地，第一请求可以为调度请求(scheduling request，简称SR)。如果第一请 求为SR，第一请求可以承载于上行控制信道或者上行数据信道。SR为UE发送给gNB的信令，用于请求gNB对该UE进行上行调度，可以使UE根据上行调度信息向gNB发送数据。通过重用SR作为第一请求，可以减少系统中信令的类型，简化系统设计。
在UE向gNB发送第一请求前，UE还可以判断其是否需要校准工作带宽资源，如果需要校准，UE向gNB发送第一请求，用于进一步降低信令开销。具体地，在UE源工作带宽资源，如果UE接收到gNB发送的第一UE特定信息，启动定时器。如果定时器为运行状态，在UE源工作带宽资源，如果UE接收到gNB发送的第一UE特定信息，重新启动所述第三定时器。第三定时器期满后，UE向gNB发送第一请求。利用第定时器，可以使UE在一段时间内没有和gNB进行通信时，可以考虑该没有通信的状态是否由gNB和UE对该UE的工作带宽资源的理解不一致造成，从而可以考虑对其工作带宽资源进行校准。
步骤803，在UE的UE校准带宽资源，gNB向UE发送UE目标工作带宽资源的信息，UE接收gNB发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于与UE进行UE的第二UE特定信息的传输。其中，UE源工作带宽资源和UE校准带宽资源不完全相同。
步骤803可以包括步骤202。
第一请求的传输和在UE校准带宽资源UE目标工作带宽资源的信息的传输之间的定时关系可能为：在时间单元n，传输第一请求，在时间单元n+k，传输UE目标工作带宽资源的信息。其中，UE目标工作带宽资源的信息的传输在第一请求的传输之后，n为整数，k大于等于0的整数。示例性地，gNB在时间单元n接收第一请求，在时间单元n+k向UE发送UE目标工作带宽资源的信息。UE在时间单元n发送第一请求，在时间单元n+k接收gNB发送的UE目标工作带宽资源的信息。当传输第一请求的时间单元和传输UE目标工作带宽资源的信息的时间单元对应的子载波间隔和/或CP类型不同时，其对应的时间单元的索引可以进行调整，本申请不做限制。示例性地，如果传输第一请求的时间单元对应的子载波间隔为60kHz，该时间单元对应的索引可能为n；如果传输UE目标工作带宽资源的信息的时间单元对应的子载波间隔为15kHz，该时间单元对应的索引可能为n/4，其中，4＝60/15。导致该现象出现的原因可能为：传输第一请求的时间单元为一个时隙，该时隙包括7个符号。传输UE目标工作带宽资源的信息的时间单元为一个时隙，该时隙包括7个符号。其中，60kHz对应的符号长度为15kHz对应的符号长度的1/4，60kHz对应的时隙长度为15kHz对应的时隙长度的1/4，因此，在相同的时间，60kHz的时隙的索引可能是15kHz的时隙的索引的4倍。其中，时隙的索引不超过该时隙的索引的取值范围。
gNB和UE可以基于系统预配置确定上述k值。可以预配置k值为常数，也可以预配置k值为n+k1至n+k1+L中任一个或多个值，其中，k1和L为整数。示例性地，k1和L为预配置的常数。
gNB还可以向UE发送信令，通过该信令指示k值。UE接收gNB发送的信令，根据信令配置确定k值。
通过本申请实施例提供的第三种带宽资源配置方法，如果UE在接收UE目标工作带宽资源的信息时，需要从UE源工作带宽资源切换至UE校准带宽资源，和/或需 要从UE校准带宽资源切换至UE目标工作带宽资源，通过该方法可以减少UE在不同带宽资源之间的切换，从而避免引入切换时间，为UE节省时域空口资源，提高数据传输速率。
进一步地，在本申请实施例提供的第一种带宽资源配置方法至第三种带宽资源配置方法中，gNB还可以在UE源工作带宽资源，向该UE发送UE目标工作带宽资源的信息。相应地，UE还可以在UE的UE源工作带宽资源，接收gNB发送的UE目标工作带宽资源的信息。在该方法中，可以配置UE目标工作带宽资源的信息在UE源工作带宽资源的发送频率高于UE目标工作带宽资源的信息在UE校准带宽资源的发送频率。示例性地，配置UE目标工作带宽资源的信息在UE源工作带宽资源的发送周期比UE目标工作带宽资源的信息在UE校准带宽资源的发送周期短。再示例性地，配置UE目标工作带宽资源的信息在UE的UE源工作带宽资源的发送周期和UE目标工作带宽资源的信息在UE校准带宽资源的发送周期相同，在该周期内，可以用于在UE源工作带宽资源传输UE目标工作带宽资源的信息的时间单元比可以用于在UE校准带宽资源传输UE目标工作带宽资源的信息的时间单元多。再示例性地，UE可以在判断其需要校准时，在UE校准带宽资源接收gNB发送的UE目标工作带宽资源的信息。通过这些方法，可以使UE判断需要校准时或者每隔较长的一段时间，才切换至UE校准带宽资源接收UE目标工作带宽资源的信息，进行UE的工作带宽资源的配置。通过该方法，可能进一步减少UE在不同带宽资源之间的切换，从而避免引入切换时间，为UE节省时域空口资源，提高数据传输速率。
下面结合图9，详细说明本申请实施例提供的第四种带宽资源配置方法，该方法对应于本申请实施例提供的第二种技术方案中gNB侧的相应设计。其中，图9所示为在gNB侧实现第四种带宽资源配置方法时对应的流程示意图。
步骤901，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤902，在UE源工作带宽资源，gNB向UE发送UE目标工作带宽资源的信息，UE接收gNB发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于与UE进行UE的第二UE特定信息的传输。
步骤902中，UE目标工作带宽资源的信息的内容，UE目标工作带宽资源的信息的传输方法等和UE目标工作带宽资源的信息相关的内容类似步骤202中的描述，这里不再赘述。步骤902和步骤202的主要区别在于：步骤202中，引入了UE校准带宽资源，在UE校准带宽资源，gNB向UE发送UE目标工作带宽资源的信息；在步骤902中，在UE源工作带宽资源，gNB向UE发送UE目标工作带宽资源的信息。
步骤903，gNB启动第二定时器；
步骤904，如果第二定时器是运行状态，如果gNB接收到UE发送的反馈，停止第二定时器，其中，该反馈为对应于携带所述UE目标工作带宽资源的信息的信道的反馈。
该反馈可能为1比特信息。
该反馈的值可以包括确认反馈，也可以包括确认反馈和非确认反馈。
当该反馈的值包括确认反馈，不包括非确认反馈时：收到反馈，gNB认为UE可能正确接收到了UE目标工作带宽资源的信息，认为UE可能将UE目标工作带宽资源作为UE的工作带宽资源，因此，gNB可以将UE目标工作带宽资源作为UE的工作带宽资源；没有收到反馈，gNB认为UE可能没有收到或者没有正确接收到UE目标工作带宽资源的信息，认为UE可能没有将UE目标工作带宽资源作为UE的工作带宽资源，认为UE可能将UE源工作带宽资源作为UE的工作带宽资源，因此，gNB可以将UE源工作带宽资源作为UE的工作带宽资源。该方法中，确认反馈还可以简称为反馈。
当该反馈的值包括确认反馈和非确认反馈时：收到确认反馈，gNB认为UE可能正确接收到了UE目标工作带宽资源的信息，认为UE可能将UE目标工作带宽资源作为UE的工作带宽资源，因此，gNB可以将UE目标工作带宽资源作为UE的工作带宽资源；没有收到反馈或者收到非确认反馈，gNB认为UE可能没有收到或者没有正确接收到了UE目标工作带宽资源的信息，认为UE可能没有将UE目标工作带宽资源作为UE的工作带宽资源，认为UE可能将UE源工作带宽资源作为UE的工作带宽资源，因此，gNB可以将UE源工作带宽资源作为UE的工作带宽资源。
步骤905，在第二定时器期满后，gNB将所述UE源工作带宽资源作为所述UE的工作带宽资源。
本申请实施例提供的第四种带宽资源配置方法中，通过gNB的回退机制，可以保证UE和gNB对UE的工作带宽资源的理解一致。
下面结合图10，详细说明本申请实施例提供的第五种带宽资源配置方法，该方法对应于本申请实施例提供的第二种技术方案中UE侧的第一种设计。其中，图10所示为在UE侧实现第五种带宽资源配置方法时对应的流程示意图。
步骤1001，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤1002，在UE源工作带宽资源，gNB向UE发送UE目标工作带宽资源的信息，UE接收gNB发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于与UE进行UE的第二UE特定信息的传输。
步骤1002同步骤902。
步骤1003，UE向gNB发送反馈，其中，该反馈为对应于携带UE目标工作带宽资源的信息的信道的反馈。
步骤1003中的反馈可以同步骤904中的反馈。
步骤1004，UE启动第三定时器。
步骤1005，在UE目标工作带宽资源，如果接收到gNB发送的第二UE特定信息，停止第三定时器。
步骤1006，第三定时器期满(expire)后，将所述UE源工作带宽资作为所述UE的工作带宽资源。
本申请实施例提供的第五种带宽资源配置方法中，直到第三定时器期满，如果UE没有接收到第二UE特定信息，UE认为gNB可能未接收或者未正确接收到反馈，UE 认为gNB可能将UE源带宽资源作为UE的工作带宽资源，因此，UE可以将UE源带宽资源作为UE的工作带宽资源，从而可能使gNB和UE对UE的工作带宽资源理解一致。
下面结合图11，详细说明本申请实施例提供的第六种带宽资源配置方法，该方法对应于本申请实施例提供的第二种技术方案中UE侧的第二种相应设计。其中，图11所示为在UE侧实现第六种带宽资源配置方法时对应的流程示意图。
步骤1101，在UE源工作带宽资源，gNB与UE进行该UE的第一UE特定信息的传输。
步骤1102，在UE源工作带宽资源，gNB向UE发送UE目标工作带宽资源的信息，UE接收gNB发送的UE目标工作带宽资源的信息。其中，UE目标工作带宽资源用于与UE进行UE的第二UE特定信息的传输。
步骤1102同步骤1002。
步骤1103，UE向gNB发送反馈，其中，该反馈为对应于携带UE目标工作带宽资源的信息的信道的反馈。
步骤1103同步骤1003。
步骤1104，UE向gNB发送第二请求；
gNB可以接收第二请求。
步骤1105，在UE目标工作带宽资源，如果UE没有接收到gNB发送的第一响应，UE将UE源工作带宽资作为UE的工作带宽资源，其中，所述第一响应为对应于所述第二请求的响应。
第一响应可以为1比特信息，还可以为UE特定信息或者其它信息，本申请不做限制。
第二请求的传输和第一响应的传输之间的定时关系类似步骤803中第一请求的传输和在UE校准带宽资源UE目标工作带宽资源的信息的传输之间的定时关系，这里不再赘述。其中，第二请求的传输对应第一请求的传输，第一响应的传输对应在UE校准带宽资源UE目标工作带宽资源的信息的传输。
本申请实施例提供的第六种带宽资源配置方法中，如果UE没有接收到第一响应，UE认为gNB可能未接收或者未正确接收到反馈，UE认为gNB可能将UE源带宽资源作为UE的工作带宽资源，因此，UE可以将UE源带宽资源作为UE的工作带宽资源，从而可能使gNB和UE对UE的工作带宽资源理解一致。
下面结合图12，详细介绍本申请实施例提供的第一种接入方法，该方法对应于本申请实施例提供的第三种设计。其中，图12所示为在UE侧实现第一种接入方法时对应的流程示意图。
步骤1201，在UE的工作带宽资源，如果UE接收到gNB发送的第三UE特定信息，启动或者重新启动第四定时器。
在UE的工作带宽资源，如果UE接收到gNB发送的第三UE特定信息，UE可以启动或者重新启动第四定时器。进一步的，第四定时器还可以在对UE的工作带宽资 源进行重配置后启动或重新启动。具体为，在UE源工作带宽资源，UE与网络设备进行该UE的第一UE特定信息的传输。在UE源工作带宽资源，网络设备向UE发送UE目标工作带宽资源的信息。相应的，在UE源工作带宽资源，UE接收网络设备发送的UE目标工作带宽资源的信息，将UE目标工作带宽资源作为该UE的工作带宽资源，UE启动第四定时器，其中，UE目标工作带宽资源用于UE与网络设备进行该UE的第三UE特定信息的传输。将UE目标工作带宽资源作为该UE的工作带宽资源后，在UE的工作带宽资源，如果UE接收到gNB发送的第三UE特定信息，UE启动或者重新启动第四定时器。
步骤1202，如果第四定时器期满，UE接入gNB。
接入gNB后，gNB可以向UE发送信息，UE可以接收gNB为其发送的信息，该信息指示了用于gNB和UE传输UE特定信息的带宽资源。示例性地，该信息为上述方法中描述的UE目标工作带宽资源的信息。
在第一种接入方法，基于定时器，在UE的工作带宽资源，如果第四定时器期满，UE认为其和gNB对UE的工作带宽资源的理解可能不一致，UE接入gNB，可以在接入后和gNB实现对UE的工作带宽资源的理解一致。

步骤1301，UE向gNB发送第三请求。
步骤1302，在UE的工作带宽资源，如果UE没有接收到gNB发送的第二响应，UE接入gNB。其中，第二响应对应于第三请求。
第二响应可以为1比特信息，还可以为UE特定信息或者其它信息，本申请不做限制。
第三请求的传输和第二响应的传输之间的定时关系类似步骤803中第一请求的传输和在UE校准带宽资源UE目标工作带宽资源的信息的传输之间的定时关系，这里不再赘述。其中，第三请求的传输对应第一请求的传输，第二响应的传输对应在校准带宽资源UE目标工作带宽资源的信息的传输。
在第二种接入方法中，基于请求反馈机制，在UE工作带宽资源，如果没有收到第二响应，UE认为其和gNB对UE的工作带宽资源的理解可能不一致，UE接入gNB，可以在接入后和gNB实现对UE的工作带宽资源的理解一致。
本申请实施例提供的第一种和第二种接入方法，UE接入gNB后，可以配置用于UE接入gNB的带宽资源为UE的工作带宽资源。进一步地，UE接入gNB后，gNB可以在用于UE接入gNB的带宽资源，向UE发送信息，为UE配置该UE的工作带宽资源，其中，该信息可以为上述描述的UE目标工作带宽资源的信息。
本申请实施例提供的第一种和第二种接入方法中，UE接入gNB的接入方法可以为本领域技术人员常用的方法。示例性地，该接入方法可以为5G系统或者LTE系统中的随机接入方法。该接入方法可以包括基于竞争的接入和非基于竞争的接入。gNB 和UE可以通过预配置确定用于UE接入gNB的带宽资源的频率资源位置信息。gNB还可以通过信令为UE配置用于UE接入gNB的带宽资源的频率资源信息。UE根据接收到的gNB发送的信令，确定gNB为其配置的用于UE接入gNB的带宽资源。其中，用于UE接入gNB的带宽资源的资源位置信息可以为步骤201中第一种频率资源位置信息至第五种频率资源位置信息中的任一种频率资源位置信息。
