在介绍本申请实施例的无线通信的方法之前，首先本申请实施例相关的技术做一介绍。Before introducing the wireless communication method according to the embodiment of the present application, firstly, the technology related to the embodiment of the present application is introduced.
带宽部分(Bandwidth Part，BWP)切换机制Bandwidth Part (BWP) switching mechanism
NR***中支持的最大信道带宽可以到400MHZ(宽带载波，wideband carrier)，如果UE一直保持工作在宽带载波上，则UE的功率消耗是很大的。根据UE实际的吞吐量来调整UE的RF带宽可以优化UE的功率消耗，这就是引入BWP的动机。The maximum channel bandwidth supported in the NR system can reach 400MHZ (wideband carrier). If the UE keeps working on the wideband carrier, the power consumption of the UE is very large. Adjusting the RF bandwidth of the UE according to the actual throughput of the UE can optimize the power consumption of the UE, which is the motivation for introducing BWP.
处于连接状态的终端，一个时刻最多只能有一个激活的下行BWP和一个激活的上行BWP。网络可以给连接态的终端配置至多4个上行BWP以及至多4个下行BWP，对于(Frequency Division Multiplexing，FDD)***，上行BWP和下行BWP之间没有显示的关联(association)关系。比如，网络可以一个连接态终端配置4个上行BWP(例如，BWP索引(index)分别是0，1，2，3)和4个下行BWP(例如，BWP index分别为0，1，2，3)，当前激活的UL BWP index可以是0，当前激活的下行BWP index可以是1；如果通过下行控制信息(Downlink Control Information，DCI)指令将下行BWP切换到另外一个BWP，比如从当前激活的DL BWP 1切换到DL BWP 2，而UL BWP可以保持不变。A terminal in a connected state can only have at most one active downlink BWP and one active uplink BWP at a time. The network can configure up to 4 uplink BWPs and up to 4 downlink BWPs for the terminal in the connected state. For the (Frequency Division Multiplexing, FDD) system, there is no association (association) relationship between the uplink BWP and the downlink BWP. For example, the network can configure a connected terminal with 4 upstream BWPs (for example, the BWP indices are 0, 1, 2, and 3, respectively) and 4 downstream BWPs (for example, the BWP indexes are 0, 1, 2, and 3, respectively). ), the currently activated UL BWP index can be 0, and the currently activated downlink BWP index can be 1; if the downlink control information (Downlink Control Information, DCI) command is used to switch the downlink BWP to another BWP, for example, from the currently activated DL BWP 1 switches to DL BWP 2, while UL BWP can remain unchanged.
可以通过BWP切换的方式来改变连接状态的终端在服务小区上激活的BWP，BWP的切换方法例如可以为以下四种：The BWP activated on the serving cell by the terminal in the connected state can be changed by means of BWP handover. For example, the BWP handover methods can be the following four:
1、基于物理下行控制信道(Physical Downlink Control Channel，PDCCH)的BWP切换1. BWP handover based on Physical Downlink Control Channel (PDCCH)
即网络控制的BWP切换。例如网络通过给终端发送PDCCH，通知终端切换的目标BWP。That is, network-controlled BWP handover. For example, the network notifies the terminal of the target BWP of handover by sending a PDCCH to the terminal.
2、基于无线资源控制(Radio Resource Control，RRC)(重)配置的BWP切换。2. BWP handover based on Radio Resource Control (RRC) (re)configuration.
即网络控制的BWP切换。例如网络设备通过在RRC(重)配置消息中携带第一激活下行BWP标识(firstActiveDownlinkBWP-Id)和/或第一激活上行BWP标识(firstActiveUplinkBWP-Id),指示终端将激活的下行BWP切换为firstActiveDownlinkBWP-Id所指示的下行BWP，和/或将激活的上行BWP切换为firstActiveUplinkBWP-Id所指示的上行BWP。That is, network-controlled BWP handover. For example, the network device instructs the terminal to switch the activated downlink BWP to firstActiveDownlinkBWP- The downlink BWP indicated by Id, and/or the activated uplink BWP is switched to the uplink BWP indicated by firstActiveUplinkBWP-Id.
3基于定时器(timer)超时的BWP切换3 BWP handover based on timer (timer) timeout
隐式的BWP切换。网络可以为终端的每个服务小区配置一个定时器(BWP去激活定时器，bwp-InactivityTimer)。如果终端当前激活的DL BWP是除缺省(default)BWP和初始(initial)DL BWP以外的BWP，每次当终端在当前激活的BWP上收到指示该UE上行或下行调度的PDCCH，或者终端收到指示该UE在当前激活的BWP上行或下行调度的PDCCH，启动或重启定时器bwp-InactivityTimer。当定时器bwp-InactivityTimer超时时，终端自动切换到default DL BWP或者initial DL BWP，其中default DL BWP和initial DL BWP由网络设备配置，例如通过RRC配置。Implicit BWP toggle. The network may configure a timer (BWP deactivation timer, bwp-InactivityTimer) for each serving cell of the terminal. If the currently activated DL BWP of the terminal is a BWP other than the default (default) BWP and the initial (initial) DL BWP, every time when the terminal receives a PDCCH indicating the uplink or downlink scheduling of the UE on the currently activated BWP, or the terminal After receiving the PDCCH indicating that the UE is scheduled in the currently activated BWP uplink or downlink, the timer bwp-InactivityTimer is started or restarted. When the timer bwp-InactivityTimer times out, the terminal automatically switches to the default DL BWP or the initial DL BWP, where the default DL BWP and the initial DL BWP are configured by the network device, for example, through RRC.
4、随机接入初始化引起的BWP切换4. BWP handover caused by random access initialization
在随机接入信道(Random Access Channel，RACH)初始化过程中，如果终端在当前激活的UL BWP上没有配置RACH机会(RACH Occasion，RO)，则终端自动将UL BWP切换到initial UL BWP，同时将DL BWP切换到initial DL BWP。During the Random Access Channel (RACH) initialization process, if the terminal does not configure the RACH opportunity (RACH Occasion, RO) on the currently activated UL BWP, the terminal automatically switches the UL BWP to the initial UL BWP, and at the same time switches the UL BWP to the initial UL BWP. DL BWP switches to initial DL BWP.
处于空闲态和非激活态的终端设备，可以通过小区定义的同步信号块(cell defining SSB，CD-SSB)获取驻留小区的主信息块(Master Information Block，MIB)和***信息块(System Information Block，SIB)1信息。其中，SIB1中指示了用于初始接入的初始BWP(initial BWP)的相关配置信息，例如，包含了initial UL BWP和initial DL BWP的相关配置信息。在initial UL BWP的相关配置信息中，网络为初始接入的终端设备配置了随机接入资源(例如，RACH-ConfigCommon)，随机接入资源和同步信号块(Synchronization Signal Block，SSB)之间的对应关系。网络设备还可以通过配置一个参考信号接收功率(Reference Signal Receiving Power，RSRP)门限(例如，rsrp-ThresholdSSB)控制终端设备的随机接入资源的选择。当随机接入过程被触发时，终端可以选择RSRP测量值满足上述RSRP门限的SSB，进一步根据随机接入资源和SSB的对应关系选择对应的随机接入资源发送随机接入前导(preamble)(即Msg1)，并在选择的SSB上接听网络发送的随机接入响应消息(即Msg2)。Terminal equipment in idle state and inactive state can obtain the master information block (Master Information Block, MIB) and system information block (System Information) of the camping cell through the cell-defining synchronization signal block (cell defining SSB, CD-SSB). Block, SIB)1 information. Wherein, SIB1 indicates the relevant configuration information of the initial BWP (initial BWP) used for initial access, for example, including the relevant configuration information of the initial UL BWP and the initial DL BWP. In the relevant configuration information of the initial UL BWP, the network configures random access resources (for example, RACH-ConfigCommon) for the initial access terminal equipment, and the random access resources and synchronization signal blocks (Synchronization Signal Block, SSB) between Correspondence. The network device may also control the selection of random access resources of the terminal device by configuring a reference signal receiving power (Reference Signal Receiving Power, RSRP) threshold (for example, rsrp-ThresholdSSB). When the random access process is triggered, the terminal can select the SSB whose RSRP measurement value meets the above-mentioned RSRP threshold, and further select the corresponding random access resource according to the corresponding relationship between the random access resource and the SSB to send the random access preamble (ie, Msg1), and receive the random access response message (ie Msg2) sent by the network on the selected SSB.
SSB波束到寻呼资源的映射Mapping of SSB beams to paging resources
寻呼(paging)的主要功能是使得网络设备能在UE处于无线资源控制(Radio Resource Control，RRC)空闲(IDLE)态或者RRC非激活(INACTIVE)态通过寻呼消息(paging message)寻呼UE，或者通过短消息(short message)通知UE***消息变更或者地震海啸/公共预警信息(适用于UE的所有RRC状态，包括连接态)。The main function of paging is to enable the network device to page the UE through a paging message when the UE is in the Radio Resource Control (RRC) idle (IDLE) state or the RRC inactive (INACTIVE) state. , or notify the UE of system message changes or earthquake and tsunami/public early warning information (applicable to all RRC states of the UE, including the connected state) through a short message.
寻呼消息的接收包括盲检由寻呼无线网络临时标识符(Paging Radio Network Temporary Identity， P-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以及接收由该PDCCH调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。其中，寻呼消息在PDSCH中传输(或者说，寻呼消息承载在PDSCH中)。The reception of the paging message includes blind detection of the Physical Downlink Control Channel (PDCCH) scrambled by the Paging Radio Network Temporary Identity (P-RNTI), and reception of the PDCCH scheduled by the PDCCH. Physical Downlink Shared Channel (PDSCH). Wherein, the paging message is transmitted in the PDSCH (or in other words, the paging message is carried in the PDSCH).
对于处于RRC_IDLE状态或者RRC_INACTIVE状态的UE，由于UE与网络之间没有其他的数据通信，为了终端省电的目的，UE可以非连续的监听paging信道，即采用paging非连续接收(Discontinuous Reception，DRX)机制。在Paging DRX机制下，UE只需要在每个DRX周期(cycle)内的一个寻呼时机(Paging Occasion，PO)期间监听paging。具体地，在一个DRX周期内，终端设备可以在寻呼无线帧(Paging Frame，PF)上的PO上去监听PDCCH。PF可以指一个无线帧，例如为固定10ms，该无线帧可以包含一个或多个PO，或者一个或多个PO的起始位置。For the UE in the RRC_IDLE state or the RRC_INACTIVE state, since there is no other data communication between the UE and the network, for the purpose of power saving of the terminal, the UE can monitor the paging channel discontinuously, that is, adopt the paging discontinuous reception (Discontinuous Reception, DRX) mechanism. Under the Paging DRX mechanism, the UE only needs to monitor paging during a paging occasion (Paging Occasion, PO) in each DRX cycle (cycle). Specifically, within one DRX cycle, the terminal device may monitor the PDCCH on the PO on the paging frame (Paging Frame, PF). PF may refer to a radio frame, for example, a fixed 10ms, and the radio frame may contain one or more POs, or the starting positions of one or more POs.
可选地，PO是S个PDCCH监听时机(monitoring occasion)组成，其中，S为管理信息库(Management Information Base，MIB)中广播的同步信号块(Synchronization Signal Block，SSB)实际发送数量。Optionally, PO is composed of S PDCCH monitoring occasions (monitoring occasions), wherein S is the actual number of synchronization signal blocks (Synchronization Signal Block, SSB) broadcast in the management information base (Management Information Base, MIB).
因此，UE在获知PF，PO和PO中的PDCCH monitoring occasion个数之后，只需知道该PO中的第一个PDCCH monitoring occasion的起始位置即可进行PDCCH的监听。可选地，该起始位置可以由高层信令配置，或者基于PO index确定。Therefore, after knowing the number of PDCCH monitoring occasions in the PF, PO and PO, the UE only needs to know the starting position of the first PDCCH monitoring occasion in the PO to monitor the PDCCH. Optionally, the starting position may be configured by higher layer signaling, or determined based on PO index.
SSB和RACH的资源映射Resource mapping for SSB and RACH
在NR相同中中，下行广播信息例如SSB，剩余***信息(Remaining System Information，RMSI)，初始接入也可以支持波束(Beam)管理机制。In the same NR, downlink broadcast information such as SSB, remaining system information (Remaining System Information, RMSI), and initial access can also support a beam (Beam) management mechanism.
具体地，SSB在时域周期内有多次发送机会，可以分别对应不同的波束。在NR***中，只有当SSB波束扫描信号“覆盖”到UE时，UE才有机会发送随机接入。Specifically, the SSB has multiple transmission opportunities in the time domain period, which may correspond to different beams respectively. In an NR system, the UE has the opportunity to send random access only when the SSB beam scan signal "covers" the UE.
即：物理随机接入信道(Physical Random Access Channel，PRACH)的发送时刻(即RO)需要和SSB发送的时刻(索引)建立映射关系。同时基站根据UE上行PRACH的资源位置，决定下行随机接入响应(Random Access Response，RAR)发送的波束。That is, the sending time (that is, the RO) of the physical random access channel (Physical Random Access Channel, PRACH) needs to establish a mapping relationship with the sending time (index) of the SSB. At the same time, the base station determines the beam sent by the downlink random access response (Random Access Response, RAR) according to the resource location of the UE's uplink PRACH.
在NTN***中，为了保证卫星的覆盖以及提升整个卫星通信***的***容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面，一颗卫星波束可以覆盖直径几十至上百公里的地面区域。In the NTN system, in order to ensure the coverage of satellites and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground, and a satellite beam can cover a diameter of Dozens to hundreds of kilometers of ground area.
卫星波束是卫星覆盖地球表面的最小单位，对应于不同的方向。通常，一个卫星通过成百上千个卫星波束来进行地球表面的覆盖。这些卫星波束可以被部署为不同的小区，也可以被部署在同一个小区内。A satellite beam is the smallest unit that a satellite covers the earth's surface, corresponding to different directions. Usually, a satellite covers the earth's surface through hundreds or thousands of satellite beams. These satellite beams can be deployed as different cells or within the same cell.
为了减低不同卫星波束之间的同频干扰，网络部署时可以针对相邻卫星波束采用不同的频点/载波/频段，如图2所示。一种实现方式是为不同的卫星波束配置同一个小区内不同的BWP，这样，终端设备在卫星波束之间移动时就不需要做小区切换，而只需要做小区内的BWP切换。其中，每个卫星波束只关联部分SSB，或者说，每个BWP只关联部分SSB，此情况下，如何进行SSB波束到paging资源的映射和RACH资源映射以避免资源的浪费是一项急需解决的问题。In order to reduce co-channel interference between different satellite beams, different frequency points/carriers/frequency bands can be used for adjacent satellite beams during network deployment, as shown in Figure 2. An implementation method is to configure different BWPs in the same cell for different satellite beams, so that the terminal equipment does not need to perform cell handover when moving between satellite beams, but only needs to perform intra-cell BWP handover. Among them, each satellite beam is only associated with a part of the SSB, or in other words, each BWP is only associated with a part of the SSB. In this case, how to perform the mapping of the SSB beam to the paging resource and the RACH resource mapping to avoid the waste of resources is an urgent need to solve problem.
图3是根据本申请实施例的无线通信的方法200的示意性流程图，该方法200可以由图1所示的通信***中的终端设备执行，如图3所示，该方法200包括如下内容：FIG. 3 is a schematic flowchart of a method 200 for wireless communication according to an embodiment of the present application. The method 200 may be executed by a terminal device in the communication system shown in FIG. 1 . As shown in FIG. 3 , the method 200 includes the following contents :

S220，所述终端设备在所述N个SSB波束中选择目标SSB波束；S220, the terminal device selects a target SSB beam from the N SSB beams;
S230，所述终端设备在所述目标SSB波束所映射的资源上进行信号发送或接收。S230, the terminal device performs signal transmission or reception on the resource mapped by the target SSB beam.
本申请实施例可以应用于NTN场景，或者也可以应用于其他配置多个BWP实现频分复用的场景，本申请并不限于此。The embodiments of the present application may be applied to NTN scenarios, or may also be applied to other scenarios in which multiple BWPs are configured to implement frequency division multiplexing, and the present application is not limited thereto.
应理解，本申请实施例的SSB波束可以为其他参考信号波束，例如信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)波束，解调参考信号(Demodulation Reference Signal,DMRS)波束等，本申请并不限于此。It should be understood that the SSB beams in this embodiment of the present application may be other reference signal beams, such as channel state information reference signal (Channel State Information Reference Signal, CSI-RS) beams, demodulation reference signal (Demodulation Reference Signal, DMRS) beams, etc., The present application is not limited to this.
需要说明的是，所述参考信号波束是通过参考信号传输实现的波束，在某种意义来说，即参考信号是以波束形态存在的，因此，参考信号波束可以称为参考信号，即SSB波束也可以称为SSB，二者可以相互替换。以下，以SSB波束为例进行说明，但本申请并不限于此。It should be noted that the reference signal beam is a beam realized by reference signal transmission. In a sense, the reference signal exists in the form of a beam. Therefore, the reference signal beam can be called a reference signal, that is, an SSB beam. Also known as SSB, the two are interchangeable. Hereinafter, the SSB beam is used as an example for description, but the present application is not limited to this.
在本申请实施例中，终端设备当前激活的第一BWP关联N个SSB波束，所述N个SSB波束为所述终端设备的服务小区的所有SSB波束中的部分，或者说，所述N小于SIB1中广播的SSB波束数量。此情况下，终端设备可以将所述N个SSB波束映射到该第一BWP上的用于信号发送或接收的上下行资源上，进一步在后续信号传输时，确定使用所述N个SSB波束中的哪个SSB波束，即可使 用哪个SSB波束映射的资源进行信号的发送或接收，从而能够避免将服务小区中的所有SSB波束都映射到所述第一BWP的资源上导致的资源浪费的问题。In this embodiment of the present application, the first BWP currently activated by the terminal device is associated with N SSB beams, and the N SSB beams are part of all SSB beams in the serving cell of the terminal device, or in other words, the N is less than Number of SSB beams broadcast in SIB1. In this case, the terminal device can map the N SSB beams to the uplink and downlink resources used for signal transmission or reception on the first BWP, and further determine to use the N SSB beams during subsequent signal transmission. The resource mapped by which SSB beam can be used for signal transmission or reception, thereby avoiding the problem of resource waste caused by mapping all SSB beams in the serving cell to the resources of the first BWP.
