When the network device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is equipped with a protocol stack including the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control protocol (Radio Link Control, RLC) layer, and the Media Access Control (Media Access Control, MAC) layer; distributed The unit is provided with a physical (Physical, PHY) layer protocol stack, and the embodiment of the present disclosure does not limit the specific implementation of the network device 12.

网络设备12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于***移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。A wireless connection can be established between the network device 12 and the terminal 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, such as The wireless air interface is a new air interface; alternatively, the wireless air interface may also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

在一个实施例中，终端11之间还可以建立E2E(End to End，端到端)或D2D(device to device，终端到终端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。In one embodiment, an E2E (End to End, end-to-end) or D2D (device to device, terminal to terminal) connection can also be established between terminals 11. For example, V2V (vehicle to vehicle, vehicle to vehicle) communication, V2I (vehicle to infrastructure, vehicle to roadside equipment) communication and V2P (vehicle to pedestrian, vehicle to person) communication in vehicle networking communication (vehicle to everything, V2X) Wait for the scene.

其中，当终端之间建立连接时，若其中一个或多个终端在终端间的通信中起到基站的功能，则该一个或多个终端也可以视为上述网络设备，而其它终端可以视为上述终端11。比如，在车联网场景中，车载终端A向另一个车载终端B上报其能力信息(比如天线能力信息)，由车载终端B根据其能力信息对车载终端A与车载终端B之间的通信进行控制，即车载终端B充当了车辆网中的头车作用，此时，车载终端B可以视为上述网络设备，而车载终端A可以视为上述终端11。Among them, when a connection is established between terminals, if one or more terminals function as a base station in the communication between terminals, the one or more terminals can also be regarded as the above-mentioned network equipment, and the other terminals can be regarded as The above-mentioned terminal 11. For example, in the Internet of Vehicles scenario, vehicle-mounted terminal A reports its capability information (such as antenna capability information) to another vehicle-mounted terminal B, and vehicle-mounted terminal B controls the communication between vehicle-mounted terminal A and vehicle-mounted terminal B based on its capability information. , that is, the vehicle-mounted terminal B acts as the leading vehicle in the vehicle network. At this time, the vehicle-mounted terminal B can be regarded as the above-mentioned network device, and the vehicle-mounted terminal A can be regarded as the above-mentioned terminal 11.

在一个实施例中，上述无线通信***还可以包含网络管理设备13。若干个网络设备分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信***中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关 (Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。In one embodiment, the above-mentioned wireless communication system may also include a network management device 13. Several network devices are connected to the network management device 13 respectively. The network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a mobility management entity (Mobility Management Entity) in an evolved packet core network (Evolved Packet Core, EPC). MME). Alternatively, the network management device can also be other core network devices, such as serving gateway (Serving GateWay, SGW), public data network gateway (Public Data Network GateWay, PGW), policy and charging rules functional unit (Policy and Charging Rules) Function, PCRF) or Home Subscriber Server (HSS), etc. The embodiment of the present disclosure does not limit the implementation form of the network management device 13 .

在目前的3GPP标准化中，提出了新的终端类型叫做Reduced capability UE或者简称为NR-lite或者Redcap终端。该类设备基于5G NR-lite中的通常需要满足如下要求：(1)低造价、低复杂度；(2)一定程度的覆盖增强；(3)功率节省；(4)有些终端是1RX有些是2RX；(5)在5G标准R18版本的Redcap用户引入之后，其带宽(BandWidth，BW)得到了进一步降低。In the current 3GPP standardization, a new terminal type called Reduced capability UE or simply NR-lite or Redcap terminal is proposed. This type of equipment based on 5G NR-lite usually needs to meet the following requirements: (1) low cost and low complexity; (2) a certain degree of coverage enhancement; (3) power saving; (4) some terminals are 1RX and some are 2RX; (5) After the introduction of Redcap users of the 5G standard R18 version, its bandwidth (BandWidth, BW) has been further reduced.

图2示出了为终端配置的具有不同带宽的BW方案，比如BW1或者BW3方案。例如，为终端配置的BW1和BW3具有不同带宽。其中，针对BW1方案，下行链路(Downlink，DL)方向和上行链路(Uplink，UL)方向上，数据(Data)信道、控制(Control)信道和射频(Radio Frequency，RF)信道不能在超出5MHz的范围以外传输。针对BW3方案，下行链路方向和上行链路方向上，控制信道和射频信道不能在超出20MHz的范围以外传输，数据信道不能在超出5MHz的范围以外传输。Figure 2 shows BW solutions with different bandwidths configured for the terminal, such as the BW1 or BW3 solution. For example, BW1 and BW3 configured for terminals have different bandwidths. Among them, for the BW1 solution, in the downlink (DL) direction and the uplink (UL) direction, the data (Data) channel, control (Control) channel and radio frequency (Radio Frequency, RF) channel cannot exceed Transmission outside the 5MHz range. For the BW3 solution, in the downlink direction and uplink direction, the control channel and radio frequency channel cannot be transmitted beyond the range of 20MHz, and the data channel cannot be transmitted beyond the range of 5MHz.

下行链路方向上，每个单元载波上，一个UE最多可以配置4个BWP，但是某个时刻只有一个激活的BWP。激活的BWP表示小区工作带宽之内UE所采用的工作带宽，在BWP之外，UE不会接收PDSCH(physical downlink shared channel，物理下行共享信道)、PDCCH(physical downlink control channel，物理下行控制信道)或者CSI-RS(channel-state information reference signal,信道状态信息参考信号)等，但是如果用于进行无线资源相关的测量或者发送SRS(Sounding Reference Signal，探测参考信号)则可以例外。In the downlink direction, on each unit carrier, a UE can be configured with up to 4 BWPs, but there is only one active BWP at a certain time. The activated BWP represents the working bandwidth used by the UE within the working bandwidth of the cell. Outside the BWP, the UE will not receive PDSCH (physical downlink shared channel, physical downlink shared channel), PDCCH (physical downlink control channel, physical downlink control channel) Or CSI-RS (channel-state information reference signal, channel state information reference signal), etc., but exceptions can be made if it is used for wireless resource-related measurements or sending SRS (Sounding Reference Signal, sounding reference signal).

针对增强型能力缩减(enhanced Reduced capability，eRedCap)终端，其主要场景为大量的传感器(sensor)和工业传感器，因此终端数量比较庞大，网络之前的寻呼容量将不足以支撑寻呼需求，因此需要网络配置多个下行的寻呼初始BWP。在eRedcap终端引入之后，如何进行回落需要重新考虑。比如对于工作在BW1的终端而言，因为当前工作的带宽已经比较小，因此其进行回落的意义不是很大。For enhanced reduced capability (eRedCap) terminals, the main scenarios are a large number of sensors and industrial sensors. Therefore, the number of terminals is relatively large, and the previous paging capacity of the network will not be enough to support the paging demand, so it is necessary to The network is configured with multiple downlink paging initial BWPs. After the introduction of the eRedcap terminal, how to perform fallback needs to be reconsidered. For example, for the terminal working on BW1, because the current working bandwidth is already relatively small, it is not very meaningful to roll back.

图3是根据一示例性实施例示出的一种带宽部分BWP切换方法的流程示意图。所述带宽部分BWP切换方法由图1所示的无线通信***中的终端执行，该终端为第一类终端。如图3所示，所述带宽部分BWP切换方法可以包括：Figure 3 is a schematic flowchart of a bandwidth partial BWP switching method according to an exemplary embodiment. The bandwidth partial BWP switching method is executed by the terminal in the wireless communication system shown in Figure 1, and the terminal is a first type terminal. As shown in Figure 3, the bandwidth partial BWP switching method may include:

步骤301：根据所述第一类终端是否配置有非激活定时器，确定所述第一类终端回落到目标下行BWP或者保持在当前激活下行BWP。Step 301: According to whether the first type terminal is configured with an inactivation timer, determine whether the first type terminal falls back to the target downlink BWP or remains at the currently activated downlink BWP.

本实施例提供的BWP切换方法由第一类终端执行。第一类终端可以为支持带宽小于预设阈值的终端，或者为特定类型终端，或者为支持的带宽小于第二类终端支持的带宽任意终端。The BWP switching method provided in this embodiment is executed by the first type of terminal. The first type of terminal may be a terminal whose supported bandwidth is less than a preset threshold, or a specific type of terminal, or any terminal whose supported bandwidth is less than the bandwidth supported by the second type of terminal.

示例性地，该第一类终端可为eRedCap终端等。所述第二类终端可包括所述第一类终端以外的任意终端，示例性地，第二类终端可为RedCap终端或增强移动带宽(enhance Mobile Broadband，eMBB)等。For example, the first type of terminal may be an eRedCap terminal or the like. The second type of terminal may include any terminal other than the first type of terminal. For example, the second type of terminal may be a RedCap terminal or enhanced mobile bandwidth (eMBB), etc.

所述第一类终端可以基于BWP工作。一个第一类终端可以被同时配置多个BWP。但该第一类终端同一时刻在一个服务小区上工作在一个激活的BWP上。The first type of terminal can work based on BWP. A Type 1 terminal can be configured with multiple BWPs at the same time. However, the first type of terminal works on an activated BWP in a serving cell at the same time.

在一些示例中，所述非激活定时器与所述终端配置的BWP之间可以是一对一的对应关系、和/或一对多的对应关系。In some examples, the inactivation timer and the BWP configured by the terminal may have a one-to-one correspondence and/or a one-to-many correspondence.

在一些示例中，所述非激活定时器包括：BWP非激活定时器和/或辅小区(Scell)去激活定时器。In some examples, the inactivation timer includes: a BWP inactivation timer and/or a secondary cell (Scell) deactivation timer.

网络设备可以为第一类终端配置各个BWP上使用的非激活定时器。若第一类终端配置有非激活定时器，则在非激活定时器超时时从当前激活的BWP自动回落到目标下行BWP。The network device can configure the inactivation timer used on each BWP for the first type terminal. If the first type of terminal is configured with an inactivation timer, it will automatically fall back from the currently activated BWP to the target downlink BWP when the inactivation timer times out.

若第一类终端未配置非激活定时器，则会保持在当前激活的下行BWP，若第一类终端未配置非激活定时器，则第一类终端不会回落到目标下行BWP的操作，从而至少减少了配置有非激活定时器的第一类终端的BWP回落。If the first type of terminal is not configured with an inactivation timer, it will remain at the currently activated downlink BWP. If the first type of terminal is not configured with an inactivation timer, the first type of terminal will not fall back to the operation of the target downlink BWP, thus At least reduce BWP fallback for Class 1 terminals configured with inactivation timers.

在一些实施例中，所述目标下行BWP为第一类终端的缺省下行BWP。In some embodiments, the target downlink BWP is the default downlink BWP of the first type of terminal.

在另一些实施例中，第一类终端配置有缺省(default)下行BWP时，目标下行BWP为缺省下行BWP。第一类终端未配置缺省下行BWP且配置有初始下行BWP时，目标下行BWP可以为初始下行BWP。In other embodiments, when the first type of terminal is configured with a default downlink BWP, the target downlink BWP is the default downlink BWP. When the first type of terminal is not configured with a default downlink BWP and is configured with an initial downlink BWP, the target downlink BWP can be the initial downlink BWP.

其中，初始下行BWP是网络设备通过***消息为终端配置的下行BWP。缺省下行BWP是网络设备基于省电考虑而为终端专门设置的一个带宽较小的BWP。The initial downlink BWP is the downlink BWP configured by the network device for the terminal through system messages. The default downlink BWP is a BWP with a smaller bandwidth specially set by the network device for the terminal based on power saving considerations.

总之，在本公开实施例中，目标下行BWP可为带宽小于第一类终端当前激活BWP的BWP，如此可以通过BWP回落，可以减少第一类终端监听的BWP，从而能够节省功耗。In short, in the embodiment of the present disclosure, the target downlink BWP can be a BWP with a bandwidth smaller than the currently activated BWP of the first type terminal. In this way, through BWP fallback, the number of BWPs monitored by the first type terminal can be reduced, thereby saving power consumption.

在一些示例中，可以根据所述第一类终端的BWP配置信息，确定所述第一类终端是否配置有当前激活下行BWP使用的非激活定时器。In some examples, it may be determined according to the BWP configuration information of the first type terminal whether the first type terminal is configured with an inactivation timer that currently activates downlink BWP usage.

其中，第一类终端可以接收来自网络设备的BWP配置消息，所述BWP配置消息用于第一类终端配置BWP使用的非激活定时器。Wherein, the first type of terminal may receive a BWP configuration message from the network device, where the BWP configuration message is used by the first type of terminal to configure an inactivation timer used by the BWP.

本公开实施例中，通过第一类终端根据第一类终端是否配置有非激活定时器，确定第一类终端回落到目标下行BWP或者保持在当前激活下行BWP，通过回落到带宽较窄的目标下行BWP，能够降低用户设备的功耗，而通过保持在当前激活下行BWP，能够抑制当前激活下行BWP的带宽较窄时不必要的BWP切换，实现对第一类终端的下行BWP的灵活切换。In the embodiment of the present disclosure, the first-type terminal determines whether the first-type terminal falls back to the target downlink BWP or remains at the currently activated downlink BWP based on whether the first-type terminal is configured with an inactivation timer. By falling back to the target with a narrower bandwidth Downlink BWP can reduce the power consumption of user equipment, and by keeping the currently activated downlink BWP, it can suppress unnecessary BWP switching when the bandwidth of the currently activated downlink BWP is narrow, achieving flexible switching of downlink BWP for the first type of terminal.

在一个实施例中，上述步骤301中，所述根据所述第一类终端是否配置有非激活定时器，确定所述第一类终端回落到目标下行BWP或者保持在当前激活下行BWP，可以包括以下至少之一：In one embodiment, in the above step 301, determining whether the first type terminal falls back to the target downlink BWP or remains at the currently activated downlink BWP according to whether the first type terminal is configured with an inactivation timer may include At least one of the following:

本实施例中，如果第一类终端未配置所述非激活定时器，会继续保持在当前激活下行BWP，并在接收到网络设备发送的BWP切换指示信息(例如，DCI)时执行下行BWP的切换。例如，BWP切换指示信息指示第一类终端激活缺省下行BWP并去激活当前激活下行BWP。In this embodiment, if the first type of terminal is not configured with the inactivation timer, it will continue to maintain the currently activated downlink BWP, and execute the downlink BWP when receiving the BWP switching indication information (for example, DCI) sent by the network device. switch. For example, the BWP switching indication information instructs the first type terminal to activate the default downlink BWP and deactivate the currently activated downlink BWP.

如果第一类终端配置有所述非激活定时器，第一类终端会在所述非激活定时器超时时回落到目标下行BWP。目标下行BWP可以为缺省下行BWP或者初始下行BWP。If the first type of terminal is configured with the inactivation timer, the first type of terminal will fall back to the target downlink BWP when the inactivation timer expires. The target downstream BWP can be the default downstream BWP or the initial downstream BWP.

本实施例中，当第一类终端配置有所述非激活定时器，若第一类终端配置有缺省下行BWP，第一类终端会在所述非激活定时器超时时回落到缺省下行BWP。In this embodiment, when the first type of terminal is configured with the inactivation timer, if the first type of terminal is configured with a default downlink BWP, the first type of terminal will fall back to the default downlink when the inactivation timer expires. BWP.

第一类终端未配置缺省下行BWP且配置有初始下行BWP时，第一类终端会在所述非激活定时器超时时可以回落到初始下行BWP。When the first-type terminal is not configured with a default downlink BWP and is configured with an initial downlink BWP, the first-type terminal can fall back to the initial downlink BWP when the inactivation timer times out.

在一些示例中，如果第一类终端配置有所述非激活定时器，第一类终端未配置缺省下行BWP且未配置初始下行BWP，第一类终端会在所述非激活定时器超时时保持在所述当前激活下行BWP。In some examples, if the first type of terminal is configured with the inactivation timer, the first type of terminal is not configured with a default downlink BWP and is not configured with an initial downlink BWP, the first type of terminal will be activated when the inactivation timer times out. Maintain the currently active downstream BWP.

在另一些示例中，如果所述第一类终端配置的非激活定时器用于回落到缺省下行BWP且不用于回落到初始下行BWP，所述第一类终端未配置所述缺省下行BWP时，确定在非激活定时器超时时保持在所述当前激活下行BWP。In other examples, if the inactivation timer configured by the first type terminal is used to fall back to the default downlink BWP and is not used to fall back to the initial downlink BWP, when the first type terminal is not configured with the default downlink BWP , determine to maintain the currently activated downlink BWP when the inactivation timer times out.

在一个实施例中，所述非激活定时器的重启条件仅仅包括如下：In one embodiment, the restart conditions of the inactivation timer only include the following:

在所述第一类终端配置有所述缺省下行BWP，且所述当前激活下行BWP不是所述缺省下行BWP的情况下，所述第一类终端接收到的数据调度的次数达到预定次数或者接收到切换到当前激活下行BWP指令。When the first type terminal is configured with the default downlink BWP and the currently activated downlink BWP is not the default downlink BWP, the number of data schedules received by the first type terminal reaches a predetermined number of times Or receive an instruction to switch to the currently active downlink BWP.

其中，所述预定次数可以根据实际应用需要进行设定，例如所述预定次数可以设为1次。The predetermined number of times can be set according to actual application needs. For example, the predetermined number of times can be set to one time.

在一个实施例中，协议约定为第一类终端(即，第一类型用户)在配置有缺省下行BWP的前提下，才可以配置BWP非激活定时器；即，若没有配置缺省下行BWP则无需配置BWP非激活定时器。In one embodiment, the protocol stipulates that the first type of terminal (that is, the first type of user) can configure the BWP inactivation timer only if the default downlink BWP is configured; that is, if the default downlink BWP is not configured Then there is no need to configure the BWP inactivation timer.

在一个实施例中，协议约定需要为第一类终端(即，第一类型用户)配置缺省下行BWP。In one embodiment, the protocol stipulates that a default downlink BWP needs to be configured for the first type of terminal (ie, the first type of user).

在一个实施例中，协议约定为第一类型用户在没有配置缺省下行BWP的前提下，若配置了BWP非激活定时器，则该BWP非激活定时器失效处理。In one embodiment, the protocol stipulates that if a BWP inactivation timer is configured for the first type of user without configuring a default downlink BWP, the BWP inactivation timer will be invalidated.

本实施例中，由于非激活定时器用于回落到缺省下行BWP且不用于回落到初始下行BWP，因此如果第一类终端未配置缺省下行BWP，那么无论第一类终端是否配置有初始下行BWP，第一类终端都会在所述非激活定时器超时时保持在所述当前激活下行BWP。In this embodiment, since the inactivation timer is used to fall back to the default downlink BWP and is not used to fall back to the initial downlink BWP, if the first type of terminal is not configured with a default downlink BWP, then no matter whether the first type of terminal is configured with an initial downlink BWP BWP, the first type of terminal will maintain the currently activated downlink BWP when the inactivation timer times out.

在一个实施例中，所述方法还包括以下至少之一：In one embodiment, the method further includes at least one of the following:

当所述第一类终端配置有所述非激活定时器，所述第一类终端配置有初始下行BWP且未配置所述缺省下行BWP时，确定在所述非激活定时器超时时目标下行BWP为所述初始下行BWP和所述当前激活下行BWP中的带宽较小的下行BWP。When the first type terminal is configured with the inactivation timer, the first type terminal is configured with an initial downlink BWP and the default downlink BWP is not configured, it is determined that the target downlink is reached when the inactivation timer times out. The BWP is the downlink BWP with smaller bandwidth among the initial downlink BWP and the currently activated downlink BWP.

本实施例中，如果所述第一类终端配置有所述非激活定时器，所述第一类终端配置有初始下行BWP且未配置所述缺省下行BWP时，第一类终端会对初始下行BWP的带宽与当前激活下行BWP的带宽进行比较，在所述非激活定时器超时时工作在带宽较小的下行BWP上。In this embodiment, if the first type terminal is configured with the inactivation timer, and the first type terminal is configured with an initial downlink BWP and the default downlink BWP is not configured, the first type terminal will respond to the initial downlink BWP. The bandwidth of the downlink BWP is compared with the bandwidth of the currently activated downlink BWP, and when the inactivation timer times out, the downlink BWP with smaller bandwidth is operated.

在一个实施例中，所述BWP为多个。不同所述备选下行BWP具有不同优先级。在进行BWP回落时，可以根据优先级回落到高优先级的BWP上。In one embodiment, there are multiple BWPs. Different candidate downlink BWPs have different priorities. When performing BWP fallback, you can fall back to the high-priority BWP according to the priority.

示例性地，BWP的带宽越小则BWP的优先级越高。For example, the smaller the bandwidth of the BWP, the higher the priority of the BWP.

在一些实施例中，所述当所述第一类终端配置有所述非激活定时器且配置有所述目标下行BWP时，确定在所述非激活定时器超时时回落到所述目标下行BWP，可以包括：In some embodiments, when the first type of terminal is configured with the inactivation timer and the target downlink BWP, it is determined to fall back to the target downlink BWP when the inactivation timer expires. , which can include:

当所述第一类终端配置有所述非激活定时器、在确定未配置有第一优先级的备选下行BWP且配置有第二优先级的备选下行BWP时，确定在所述非激活定时器超时时回落到第二优先级的所述备选下行BWP；When the first type terminal is configured with the inactivation timer, and when it is determined that the alternative downlink BWP of the first priority is not configured and the alternative downlink BWP of the second priority is configured, it is determined that the inactivation timer is configured. When the timer times out, fall back to the alternative downlink BWP of the second priority;

或者，当所述第一类终端配置有所述非激活定时器、在确定配置有第一优先级的备选下行BWP且配置有第二优先级的备选下行BWP时，确定在所述非激活定时器超时时回落到第一优先级的所述备选下行BWP；其中，所述第一优先级高于所述第二优先级。Or, when the first type terminal is configured with the inactivation timer, and when it is determined that the first priority candidate downlink BWP is configured and the second priority candidate downlink BWP is configured, it is determined that the non-activation timer is configured. The alternative downlink BWP falls back to the first priority level when the activation timer expires; wherein the first priority level is higher than the second priority level.

其中，目标下行BWP的备选下行BWP的优先级，可用于确定该备选下行是否能够优先作为在非激活定时器超时时回落的目标下行BWP。Among them, the priority of the candidate downstream BWP of the target downstream BWP can be used to determine whether the candidate downstream BWP can be prioritized as the target downstream BWP that falls back when the inactivation timer times out.

本实施例中，网络设备可以在为终端配置下行BWP时，可以为下行BWP配置对应的优先级，每个BWP对应一个优先级，每个BWP对应的优先级可以相同，也可以不同。另外，备选下行BWP的优先级可以是第一类终端根据每一个BWP的带宽设定该BWP对应的优先级，BWP的带宽越小，BWP对应的优先级越高，也可以第一类终端根据BWP的传输质量设定BWP对应的优先级。In this embodiment, the network device can configure corresponding priorities for the downlink BWPs when configuring the downlink BWP for the terminal. Each BWP corresponds to a priority, and the priorities corresponding to each BWP can be the same or different. In addition, the priority of the candidate downlink BWP can be that the first type terminal sets the priority corresponding to each BWP according to the bandwidth of the BWP. The smaller the bandwidth of the BWP, the higher the priority corresponding to the BWP. It can also be the first type terminal. Set the priority corresponding to BWP according to the transmission quality of BWP.

在一个实施例中，所述目标下行BWP的备选下行BWP包括：缺省下行BWP或者初始下行BWP。In one embodiment, the candidate downlink BWPs of the target downlink BWP include: a default downlink BWP or an initial downlink BWP.

在一些示例中，缺省下行BWP的优先级为第一优先级，初始下行BWP的优先级为第二优先级。In some examples, the priority of the default downlink BWP is the first priority, and the priority of the initial downlink BWP is the second priority.

本实施例中，当第一类终端配置有非激活定时器且配置有缺省下行BWP时，第一类终端会在非激活定时器超时时回落到缺省下行BWP。当第一类终端配置有非激活定时器、在确定未配置有缺省下行BWP且配置有初始下行BWP时，第一类终端可以在非激活定时器超时时回落到初始下行BWP。In this embodiment, when the first type of terminal is configured with an inactivation timer and a default downlink BWP, the first type of terminal will fall back to the default downlink BWP when the inactivation timer times out. When the first type terminal is configured with an inactivation timer and it is determined that the default downlink BWP is not configured and the initial downlink BWP is configured, the first type terminal can fall back to the initial downlink BWP when the inactivation timer expires.

The third type of terminal may include: any terminal that supports a larger bandwidth than the second type of terminal. For example, the third type of terminal may include: enhanced mobile broadband (eMBB) terminal.

The system information block can be, for example, System Information Block 1 (SIB1).

本实施例中，如果第一类终端配置有缺省下行BWP，第一类终端会在非激活定时器超时时回落到缺省下行BWP。如果第一类终端未配置缺省下行BWP且配置有初始下行BWP，第一类终端会在非激活定时器超时时回落到初始下行BWP。如果第一类终端未配置缺省下行BWP且未配置初始下行BWP，第一类终端会在非激活定时器超时时回落到为第二类终端配置的初始下行BWP或者为所述第三类终端配置的初始下行BWP。其中，为第二类终端配置的初始下行BWP的优先级高于为所述第三类终端配置的初始下行BWP。In this embodiment, if the first type of terminal is configured with a default downlink BWP, the first type of terminal will fall back to the default downlink BWP when the inactivation timer times out. If the first type of terminal is not configured with a default downlink BWP and is configured with an initial downlink BWP, the first type of terminal will fall back to the initial downlink BWP when the inactivation timer times out. If the first type of terminal is not configured with a default downlink BWP and is not configured with an initial downlink BWP, the first type of terminal will fall back to the initial downlink BWP configured for the second type of terminal or the third type of terminal when the inactivation timer times out. Configured initial downlink BWP. Wherein, the initial downlink BWP configured for the second type of terminal has a higher priority than the initial downlink BWP configured for the third type of terminal.

本实施例中，第一类终端可以基于网络设备发送的携带于***信息块中的初始下行BWP的配置信息，进行配置初始下行BWP。In this embodiment, the first type of terminal may configure the initial downlink BWP based on the initial downlink BWP configuration information carried in the system information block sent by the network device.

在一些示例中，第一类终端的初始下行BWP的配置信息或者所述配置信息的指示信息，可以携带于***信息块1(SIB1)中或者新创建的SIB中。In some examples, the configuration information of the initial downlink BWP of the first type terminal or the indication information of the configuration information may be carried in the system information block 1 (SIB1) or in the newly created SIB.

例如，使用SIB1中的预留比特的全部或部分表示所述第一类终端的初始下行BWP的配置信息或者所述配置信息的指示信息。该指示信息用于通知第一类终端在哪个***信息消息或SIB中可以接收到第一类终端的初始下行BWP的配置信息。For example, all or part of the reserved bits in SIB1 are used to represent the configuration information of the initial downlink BWP of the first type terminal or the indication information of the configuration information. The indication information is used to notify the first type terminal in which system information message or SIB it can receive the initial downlink BWP configuration information of the first type terminal.

又例如，使用新创建的SIB携带第一类终端的初始下行BWP的配置信息或者所述配置信息的指示信息。其中，新创建的SIB例如SIB1-bis(System Information Block Type 1bis)。For another example, the newly created SIB is used to carry the configuration information of the initial downlink BWP of the first type terminal or the indication information of the configuration information. Among them, the newly created SIB is such as SIB1-bis (System Information Block Type 1bis).

在一些示例中，初始下行BWP可以具有以下搜索空间中至少一个：随机访问响应(Random Access Response，RAR)搜索空间、寻呼搜索空间以及***消息搜索空间。In some examples, the initial downstream BWP may have at least one of the following search spaces: a Random Access Response (RAR) search space, a paging search space, and a system message search space.

在一些示例中，初始下行BWP为一个时，第一类终端可以将该初始下行BWP作为目标下行BWP。In some examples, when the initial downlink BWP is one, the first type of terminal may use the initial downlink BWP as the target downlink BWP.

在一些示例中，初始下行BWP为多个时，第一类终端可以按照规则选择一个初始下行BWP作为目标下行BWP，比如随机选择一个初始下行BWP；也可以选择预定类型的初始下行BWP作为目标下行BWP，比如预定类型为接收寻呼消息的初始下行BWP。In some examples, when there are multiple initial downlink BWPs, the first type of terminal can select an initial downlink BWP as the target downlink BWP according to the rules, such as randomly selecting an initial downlink BWP; it can also select a predetermined type of initial downlink BWP as the target downlink BWP. BWP, for example, the predetermined type is the initial downlink BWP for receiving paging messages.

在一些示例中，接收寻呼消息的初始下行BWP可以为多个，比如对第一类终端配置两个下行初始BWP，其中包含寻呼搜索空间，用于接收寻呼消息，可以从接收寻呼消息的两个下行初始BWP中选择一个下行初始BWP作为目标下行BWP。In some examples, there can be multiple initial downlink BWPs for receiving paging messages. For example, two initial downlink BWPs are configured for the first type of terminal, which include paging search spaces for receiving paging messages. The paging messages can be received from Select one of the two downstream initial BWPs of the message as the target downstream BWP.

具体地，预设选择规则可以按照第一类终端的标识信息(UE-ID)对下行初始BWP总个数取模；按照取模的索引(index)，选择对应标号的接收寻呼消息的初始下行BWP作为所述目标下行BWP。Specifically, the preset selection rule can modulate the total number of downlink initial BWPs according to the identification information (UE-ID) of the first type of terminal; according to the modulo index (index), select the initial number of the corresponding number to receive the paging message. The downstream BWP serves as the target downstream BWP.

例如，为第一类终端配置了三个接收寻呼消息的初始下行BWP，并按照0、1、2进行编排，将取模运算结果作为index可以对应到0、1或2，作为所述目标下行BWP。For example, three initial downlink BWPs for receiving paging messages are configured for the first type of terminal, and are arranged according to 0, 1, and 2. The modulo operation result is used as an index and can correspond to 0, 1, or 2 as the target. Downward BWP.

在所述第一类终端配置有所述缺省下行BWP，且所述当前激活下行BWP不是所述缺省下行BWP的情况下，所述第一类终端接收到的数据调度的次数达到预定次数或者接收到切换到当前激活下行BWP指令；When the first type terminal is configured with the default downlink BWP and the currently activated downlink BWP is not the default downlink BWP, the number of data schedules received by the first type terminal reaches a predetermined number of times Or receive an instruction to switch to the currently active downlink BWP;

在所述第一类终端未配置所述缺省下行BWP，且所述当前激活下行BWP不是所述初始下行BWP的情况下，所述第一类终端接收到的数据调度的次数达到预定次数或者接收到切换到当前激活下行BWP指令。In the case that the first type terminal is not configured with the default downlink BWP, and the currently activated downlink BWP is not the initial downlink BWP, the number of data schedules received by the first type terminal reaches a predetermined number of times or The command to switch to the currently active downlink BWP is received.

本实施例中，所述非激活定时器的重启条件被满足时，所述非激活定时器重启，并用于对第一类终端当前激活下行BWP不活动的时间进行计时，从而保证可以及时地将第一类终端当前激活下行BWP回落到目标下行BWP。In this embodiment, when the restart condition of the inactivation timer is met, the inactivation timer is restarted and used to time the time when the first type terminal currently activates the downlink BWP and is inactive, thereby ensuring that the downlink BWP can be inactive in a timely manner. The currently activated downlink BWP of the first type terminal falls back to the target downlink BWP.

The method is executed by the network device in the wireless communication system shown in FIG. 1 . As shown in Figure 4, the bandwidth partial BWP configuration method may include:

步骤401：根据目标终端的类型，确定是否为所述目标终端配置非激活定时器，其中，所述非激活定时器，用于供所述目标终端回落到目标下行BWP。Step 401: Determine whether to configure an inactivation timer for the target terminal according to the type of the target terminal, where the inactivation timer is used for the target terminal to fall back to the target downlink BWP.

网络设备可以为目标终端配置各个BWP上使用的非激活定时器。若目标终端配置有非激活定时器，则目标终端开启从当前激活的BWP自动回落到目标下行BWP的功能。若目标终端未配置非激活定时器，则目标终端会保持在当前激活的下行BWP。The network device can configure the inactivation timer used on each BWP for the target terminal. If the target terminal is configured with an inactivation timer, the target terminal enables the function of automatically falling back from the currently activated BWP to the target downlink BWP. If the target terminal is not configured with an inactivation timer, the target terminal will remain in the currently activated downlink BWP.

在一些示例中，目标终端配置有缺省下行BWP时，目标下行BWP为缺省下行BWP；目标终端未配置缺省下行BWP且配置有初始下行BWP时，目标下行BWP可以为初始下行BWP。In some examples, when the target terminal is configured with a default downlink BWP, the target downlink BWP is the default downlink BWP; when the target terminal is not configured with a default downlink BWP and is configured with an initial downlink BWP, the target downlink BWP can be the initial downlink BWP.

The method is executed by the network device in the wireless communication system shown in FIG. 1 . As shown in Figure 5, the bandwidth part BWP determination method may include:

步骤501：根据第一类终端是否配置有非激活定时器，确定所述第一类终端当前工作的下行BWP；其中，所述第一类终端当前工作的下行BWP，用于供所述网络设备进行下行信息的发送。Step 501: Determine the downlink BWP currently working for the first type terminal according to whether the first type terminal is configured with an inactivation timer; wherein the downlink BWP currently working for the first type terminal is used for the network device Send downlink information.

在一些示例中，所述非激活定时器包括：BWP非激活定时器和/或辅小区去激活定时器。In some examples, the inactivation timer includes: a BWP inactivation timer and/or a secondary cell deactivation timer.

在另一些实施例中，第一类终端配置有缺省下行BWP时，目标下行BWP为缺省下行BWP。第一类终端未配置缺省下行BWP且配置有初始下行BWP时，目标下行BWP可以为初始下行BWP。In other embodiments, when the first type of terminal is configured with a default downlink BWP, the target downlink BWP is the default downlink BWP. When the first type of terminal is not configured with a default downlink BWP and is configured with an initial downlink BWP, the target downlink BWP can be the initial downlink BWP.

总之，在本公开实施例中，目标下行BWP可为带宽小于第一类终端当前激活下行BWP的BWP，如此可以通过BWP回落，可以减少第一类终端监听的BWP，从而能够节省功耗。In short, in the embodiment of the present disclosure, the target downlink BWP can be a BWP with a bandwidth smaller than the currently activated downlink BWP of the first type of terminal.

其中，该特定类型终端可以为增强型Redcap类型终端。The specific type of terminal may be an enhanced Redcap type terminal.

基于上述实施例，为特定类型终端不配置BWP非激活定时器。Based on the above embodiment, the BWP inactivation timer is not configured for a specific type of terminal.

作为一个示例：若为特定类型终端配置BWP非激活定时器；该BWP非激活定时器仅用于特定类型终端回落到缺省下行BWP。As an example: If a BWP inactivation timer is configured for a specific type of terminal; the BWP inactivation timer is only used for the specific type of terminal to fall back to the default downlink BWP.

作为一个示例：若为特定类型终端配置了缺省下行BWP，则该BWP非激活定时器超时之后，特定类型终端回落到缺省下行BWP；若没有配置缺省下行BWP，则继续保持在当前工作的下行BWP。As an example: If a default downlink BWP is configured for a specific type of terminal, after the BWP inactivation timer times out, the specific type of terminal falls back to the default downlink BWP; if no default downlink BWP is configured, it will continue to work at the current level.

作为一个示例：目标下行BWP则切换到SIB1中为第二类用户配置的初始下行BWP(可以为eMBB用户配置的初始下行BWP或者为R17的Redcap用户配置的初始下行BWP)。As an example: the target downstream BWP is switched to the initial downstream BWP configured for the second type of users in SIB1 (the initial downstream BWP can be configured for eMBB users or the initial downstream BWP configured for R17 Redcap users).

进一步地，为R17的Redcap用户配置的下行初始BWP的优先级高于为eMBB用户配置的初始下行BWP的优先级。Further, the priority of the downlink initial BWP configured for R17 Redcap users is higher than the priority of the initial downlink BWP configured for eMBB users.

作为另一个示例：目标下行BWP则切换到SIB1-bis或者SIB1中为特定类型用户配置的下行初始BWP(若仅仅配置了一个)。As another example: the target downstream BWP is switched to SIB1-bis or the downstream initial BWP configured for a specific type of user in SIB1 (if only one is configured).

进一步地，若没有为特定类型用户配置的下行初始BWP，则切换到SIB1中为第二类用户配置的初始下行BWP。Further, if there is no downlink initial BWP configured for a specific type of user, switch to the initial downlink BWP configured for the second type of user in SIB1.

作为又一个示例：目标下行BWP则切换到SIB1-bis中为特定类型用户配置的下行BWP(若配置了多个)，则按照如下规则选择：As another example: the target downstream BWP is switched to the downstream BWP configured for a specific type of user in SIB1-bis (if multiple are configured), and is selected according to the following rules:

作为另一种实施方式：预定类型的下行初始BWP可以是为特定类型终端配置的包含***消息搜索空间的下行初始BWP。As another implementation manner: the predetermined type of downlink initial BWP may be a downlink initial BWP configured for a specific type of terminal and including a system message search space.

作为又一种实施方式：预定类型的下行初始BWP可以是为特定类型终端配置的任意一种类型的下行初始BWP：As another implementation manner: the predetermined type of downlink initial BWP may be any type of downlink initial BWP configured for a specific type of terminal:
