Method performed by user equipment and user equipment

Technical field

本发明涉及无线通信技术领域，具体涉及由用户设备执行的方法以及相应的用户设备。The present invention relates to the field of wireless communication technology, and in particular, to a method executed by user equipment and a corresponding user equipment.

Background technique

2016年3月，在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)RAN#71次全会上，一个关于5G技术标准的新的研究项目(参见非专利文献1)获得批准。该研究项目的目的是开发一个新的无线(New Radio：NR)接入技术以满足5G的所有应用场景、需求和部署环境。NR主要有三个应用场景：增强的移动宽带通信(Enhanced Mobile Broadband：eMBB)、大规模机器类通信(massive Machine Type Communication：mMTC)和超可靠低延迟通信(Ultra-Reliable and Low Latency Communications：URLLC)。2017年6月，在3GPP RAN#75次全会上，相应的5G NR的工作项目(参见非专利文献2)获得批准。In March 2016, at the 3GPP (3rd Generation Partnership Project) third-generation partnership project RAN # 71 plenary session, a new research project on 5G technology standards (see Non-Patent Document 1) was approved. The purpose of this research project is to develop a new wireless (New Radio: NR) access technology to meet all 5G application scenarios, needs and deployment environments. NR has three main application scenarios: enhanced mobile broadband communication (Enhanced Mobile Broadband: eMBB), large-scale machine type communication (massive Machine Type Communication: mMTC) and ultra-reliable low-latency communication (Ultra-Reliable and Low Latency Communications: URLLC) . In June 2017, at the 3GPP #RAN # 75 plenary session, the corresponding 5G NR work item (see Non-Patent Document 2) was approved.

5G支持寻呼(paging)机制，例如，当网络需要发起对某个UE的连接，而该UE处于RRC_IDLE或者RRC_INACTIVE状态时，网络可以在某个或某些区域(例如，跟踪区域，tracking area)发送寻呼消息(paging message)，对该UE发起寻呼。另一方面，为减少UE的耗电，5G还支持DRX(Discontinuous Reception，不连续接收)，其基本机制是给UE配置一个DRX周期(DRX cycle)，使得UE在一个DRX周期内只有一部分时间需要监听(monitor)下行的控制信令，例如寻呼相关的控制信令，其他时间可以处于休眠状态(例如，可以将接收机关闭)。5G supports paging mechanism. For example, when the network needs to initiate a connection to a UE, and the UE is in the RRC_IDLE or RRC_INACTIVE state, the network can be in a certain area or certain areas (eg, tracking area, tracking area) Send a paging message (paging messages) to initiate paging to the UE. On the other hand, in order to reduce the power consumption of the UE, 5G also supports DRX (Discontinuous Reception). The basic mechanism is to configure a DRX cycle for the UE, so that the UE only needs part of the time in a DRX cycle. Monitor downlink control signaling, such as paging-related control signaling, and can be in a sleep state at other times (for example, the receiver can be turned off).

在物理层，寻呼消息是承载在PDSCH(Physical Downlink Shared Channel，物理下行共享信道)上的，而PDSCH是通过PDCCH(Physical Downlink Control Channel，物理下行控制信道)进行调度的。一个PDCCH由一个或者多个CCE(control-channel element，控制信道元素)组成，而一个CCE又由多个(例如，6个)PEG(resource-element group，资源元素组)组成，而REG则在CORESET(control-resource set，控制资源集)内定义。一个CORESET在频域包含多个资源块(每个资源块由频域上12个连续的子载波组成)，在时域上包含一个或者多个(例如，1个，或者2个，或者3个)OFDM符号。At the physical layer, paging messages are carried on PDSCH (Physical Downlink Shared Channel), and PDSCH is scheduled through PDCCH (Physical Downlink Control Channel). A PDCCH is composed of one or more CCE (control-channel elements), and a CCE is composed of multiple (for example, 6) PEG (resource-element groups), and REG is in Defined in CORESET (control-resource set). A CORESET contains multiple resource blocks in the frequency domain (each resource block consists of 12 consecutive subcarriers in the frequency domain), and contains one or more in the time domain (for example, 1, or 2, or 3) ) OFDM symbol.

基站可以配置某些UE是否监听寻呼。例如，可以根据参数pagingSearchSpace(又称为paging-SearchSpace)是否已配置(例如通过专用信令进行配置)确定是否在相应的BWP上监听寻呼。The base station can configure whether certain UEs monitor paging. For example, it can be determined whether to monitor paging on the corresponding BWP according to whether the parameter pagingSearchSpace (also called paging-SearchSpace) has been configured (for example, through dedicated signaling).

UE在由网络配置的一些可能出现PDCCH传输的时域和频域的位置监听PDCCH。这些时域和频域的位置可以关联到某个CORESET，以及该CORESET在时域上出现的模式(例如出现的周期)。这样的配置信息可以称为搜索空间(search space)配置信息，其中用于寻呼的搜索空间可以称为寻呼搜索空间(paging search space)。每个搜索空间都有一个搜索空间标识符(search space ID)，例如，可以通过参数pagingSearchSpace配置寻呼搜索空间的标识符。图6是搜索空间配置的一个例子，其中对搜索空间中的所有PDCCH监听机会(PDCCH monitoring occasion)按照时间顺序由小到大进行编号。The UE monitors the PDCCH at some positions configured by the network in the time and frequency domains where PDCCH transmission may occur. The positions of these time and frequency domains can be associated with a CORESET, and the mode in which the CORESET appears in the time domain (eg, the period of occurrence). Such configuration information may be referred to as search space configuration information, and the search space used for paging may be referred to as paging search space. Each search space has a search space identifier (search space ID). For example, the identifier of the paging search space can be configured through the parameter pagingSearchSpace. FIG. 6 is an example of a search space configuration, in which all PDCCH monitoring opportunities (PDCCH monitoring) in the search space are numbered in chronological order from small to large.

寻呼搜索空间所定义的PDCCH监听机会中，可以只有一部分用于监听寻呼，这部分PDCCH监听机会称为寻呼PDCCH监听机会(PDCCH monitoring occasion for paging)。一个给定的UE可以只监听所述寻呼PDCCH监听机会中的一部分。Among the PDCCH monitoring opportunities defined in the paging search space, only a part may be used to monitor paging. This part of the PDCCH monitoring opportunities is called PDCCH monitoring opportunity (PDCCH monitoring opportunity for paging). A given UE may monitor only a part of the paging PDCCH monitoring opportunities.

每个DRX周期中定义了一个或者多个PF(paging frame，寻呼帧)，每个PF对应一个或者多个PO(paging occasion，寻呼机会)，而每个PO又对应一组寻呼PDCCH监听机会。在多波束操作(multi-beam operation)中，每个PO可以对应一次波束扫描(beam sweeping)，每个PO所对应的寻呼PDCCH监听机会的个数可以等于一次波束扫描所需要的寻呼PDCCH监听机会的个数。图7是说明参数pagingSearchSpace所指示的搜索空间的ID是0时，DRX周期、PF、PO、PDCCH监听机会和寻呼PDCCH监听机会之间的关系的一个例子，其中SSB 0，SSB 1，……，SSB 63表示64个索引分别为0，1，……，63的候选SSB(candidate SS/PBCH block，或者candidate SSB)，而SSB 1和SSB 9是其中实际传输的SSB(一般来说，不同的SSB可以使用不同的传输波束)。One or more PFs (paging frames) are defined in each DRX cycle, each PF corresponds to one or more POs (paging occasions), and each PO corresponds to a group of paging PDCCH monitoring opportunity. In multi-beam operation, each PO can correspond to a beam sweep (beam sweeping), and the number of paging PDCCH monitoring opportunities corresponding to each PO can be equal to the paging PDCCH required for one beam scan The number of monitoring opportunities. 7 is an example illustrating the relationship between the DRX cycle, PF, PO, PDCCH monitoring opportunity and paging PDCCH monitoring opportunity when the search space ID indicated by the parameter pagingSearchSpace is 0, where SSB 0, SSB 1, ... , SSB 63 means 64 candidate SSBs (candidate SS / PBCH block, or candidate SSB) with indexes 0, 1, ..., 63 respectively, and SSB 1 and SSB 9 are the actual SSBs transmitted (generally, different The SSB can use different transmission beams).

在一个DRX周期中，UE可以根据一个UE标识符(例如，根据参数5G-S-TMSI确定的UE标识，如UE_ID＝5G-S-TMSI mod 1024)和/或一个为接收寻呼而确定的参考传输波束(例如，UE接收MIB或者SIB1时所使用的SSB所对应的传输波束)和/或其他参数确定其中一个PF，以及所述PF所对应的一个PO，以及所述PO所对应的一个寻呼PDCCH监听机会。In a DRX cycle, the UE may be based on a UE identifier (for example, a UE identifier determined according to the parameter 5G-S-TMSI, such as UE_ID = 5G-S-TMSI mod 1024) and / or a determination for receiving paging Determine one of the PFs, and one PO corresponding to the PF, and one corresponding to the PO with reference to the transmission beam (for example, the transmission beam corresponding to the SSB used by the UE when receiving the MIB or SIB1) and / or other parameters Paging PDCCH monitoring opportunities.

例如，PF的SFN(System Frame Number，系统帧号，简称帧号，其所指示的“系统帧”也可以称为radio frame即“无线帧”，或者简称“帧”)可以通过下式进行计算：For example, PFN's SFN (System Frame Number, system frame number, abbreviated frame number, the "system frame" indicated by it may also be called radio frame (wireless frame), or simply "frame") can be calculated by the following formula :

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)(SFN + PF_offset) mod = T = (TdivN) * (UE_ID modN)

其中，among them,

■SFN是所要计算的PF所在的系统帧号。SFN is the system frame number where the PF to be calculated is located.

■PF_offset是一个用于计算PF的偏移值。■ PF_offset is an offset value used to calculate PF.

●T是DRX周期。例如，一个缺省的DRX周期可以由寻呼控制信道配置信息(例如PCCH-Config IE所指示的配置信息)中的参数defaultPagingCycle进行配置。其中，在现有的3GPP标准规范中，寻呼控制信道配置信息的定义如下：● T is the DRX cycle. For example, a default DRX cycle may be configured by the parameter defaultPagingCycle in the paging control channel configuration information (such as the configuration information indicated by PCCH-ConfigIE). Among them, in the existing 3GPP standard specifications, the paging control channel configuration information is defined as follows:

■N是DRX周期内的PF的个数。N和PF_offset一起可以通过寻呼控制信道配置信息中的参数nAndPagingFrameOffset进行配置。■ N is the number of PFs in the DRX cycle. N and PF_offset can be configured through the parameter nAndPagingFrameOffset in the paging control channel configuration information.

PO的编号可以通过下式进行计算：The PO number can be calculated by the following formula:

i_s＝floor(UE_ID/N)mod Nsi_s = floor (UE_ID / N) mod Ns

其中，among them,

■Ns是每个PF所对应的PO的个数。Ns可以通过寻呼控制信道配置信息中的参数ns进行配置。■ Ns is the number of POs corresponding to each PF. Ns can be configured through the parameter ns in the paging control channel configuration information.

若参数pagingSearchSpace所指示的搜索空间的ID是0，则UE可以根据类型0-PDCCH公共搜索空间(Type0-PDCCH common search space，即用于监听SIB1的调度信息的搜索空间，其ID为0)中从SSB索引到PDCCH监听机会的映射方式确定PDCCH监听机会，并将所确定的PDCCH监听机会作为寻呼PDCCH监听机会。例如，在图7中，假设Ns＝1，且基站只传输了SSB1和SSB9(即一次波束扫描只涉及2个波束)，则UE要么检测到SSB1，要么检测到SSB9，并按照所检测到的SSB的索引根据类型0-PDCCH公共搜索空间中从SSB索引到PDCCH监听机会的映射方式计算寻呼PDCCH监听机会的位置。例如，在SSB和CORESET复用模式2下，若SSB的子载波间隔是120kHz，PDCCH的子载波间隔是60kHz，则SSB索引i所对应的PDCCH监听机会的帧号f、帧内的时隙号s以及第一个符号的索引b可以通过如下方式确定：If the ID of the search space indicated by the parameter pagingSearchSpace is 0, then the UE can search the SIB1 scheduling information according to the type 0-PDCCH common search space (Type 0-PDCCH common search space, which is ID 0) The mapping method from the SSB index to the PDCCH monitoring opportunity determines the PDCCH monitoring opportunity, and uses the determined PDCCH monitoring opportunity as the paging PDCCH monitoring opportunity. For example, in FIG. 7, assuming Ns = 1, and the base station only transmits SSB1 and SSB9 (that is, only one beam scan involves two beams), then the UE either detects SSB1 or SSB9, and according to the detected The index of the SSB calculates the position of the paging PDCCH monitoring opportunity according to the mapping method from the SSB index to the PDCCH monitoring opportunity in the type 0-PDCCH common search space. For example, in SSB and CORESET multiplexing mode 2, if the SSB subcarrier interval is 120 kHz and the PDCCH subcarrier interval is 60 kHz, the frame number f of the PDCCH monitoring opportunity corresponding to the SSB index i, and the slot number in the frame s and the index b of the first symbol can be determined as follows:

●f等于索引为i的SSB所在的帧号。● f is equal to the frame number of the SSB with index i.

●s等于索引为i的SSB所在的时隙号。● s is equal to the slot number where the SSB with index i is located.

●若i＝4k，则b＝0；若i＝4k+1，则b＝1；若i＝4k+2，则b＝6；若 i＝4k+3，则b＝7。其中，k＝0，1，...，15。● If i = 4k, then b = 0; if i = 4k + 1, then b = 1; if i = 4k + 2, then b = 6; if i = 4k + 3, then b = 7. Among them, k = 0, 1, ..., 15.

若参数pagingSearchSpace所指示的寻呼搜索空间的ID是一个非0值，则UE将从PF中的第一个PDCCH监听机会开始的所有由所述寻呼搜索空间所定义的PDCCH监听机会中和上行符号不重叠的PDCCH监听机会确定为寻呼PDCCH监听机会，并将这些寻呼PDCCH监听机会从0开始依次进行编号。每个PO包含S个连续的寻呼PDCCH监听机会，其中S可以等于小区中实际传输的SSB个数(例如通过SIB1中的参数ssb-PositionsInBurst进行指示)。每个PO中的第K个寻呼PDCCH监听机会对应小区中第K个实际传输的SSB(例如，UE可以认为每个PO中的第K个寻呼PDCCH监听机会所使用的传输波束和小区中第K个实际传输的SSB所使用的传输波束是一样的)，其中K的取值范围是1到S。UE监听第(i_s+1)个PO，其中i_s的取值范围是0到Ns-1。若参数firstPDCCH-MonitoringOccasionOfPO已配置，则第(i_s+1)个PO起始于参数firstPDCCH-MonitoringOccasionOfPO所指示的寻呼PDCCH监听机会，否则第(i_s+1)个PO起始于编号为(i_s*S)的寻呼PDCCH监听机会。If the ID of the paging search space indicated by the parameter pagingSearchSpace is a non-zero value, the UE will neutralize and uplink all PDCCH monitoring opportunities defined by the paging search space starting from the first PDCCH monitoring opportunity in the PF PDCCH monitoring opportunities with non-overlapping symbols are determined as paging PDCCH monitoring opportunities, and these paging PDCCH monitoring opportunities are numbered sequentially from 0. Each PO contains S consecutive paging PDCCH monitoring opportunities, where S may be equal to the number of SSBs actually transmitted in the cell (for example, indicated by the parameter ssb-PositionsInBurst in SIB1). The Kth paging PDCCH monitoring opportunity in each PO corresponds to the Kth actually transmitted SSB in the cell (for example, the UE may consider the transmission beam and cell used by the Kth paging PDCCH monitoring opportunity in each PO The transmission beam used by the Kth actually transmitted SSB is the same), where K ranges from 1 to S. The UE monitors the (i_s + 1) th PO, where the value range of i_s is 0 to Ns-1. If the parameter firstPDCCH-MonitoringOccasionOfPO is configured, the (i_s + 1) PO starts with the paging PDCCH monitoring opportunity indicated by the parameter firstPDCCH-MonitoringOccasionOfPO, otherwise the (i_s + 1) PO starts with the number (i_s * S) Paging PDCCH monitoring opportunities.

在现有的3GPP 5G标准规范关于寻呼机制的设计中，若参数pagingSearchSpace所指示的寻呼搜索空间的ID是一个非0值，如前所述，确定寻呼PDCCH监听机会是从PF中的第一个PDCCH监听机会开始的。这要求任何一个PF都至少包含一个PDCCH监听机会。但是所述要求并不是在所有参数配置下总能满足，例如，当所述寻呼搜索空间的周期大于10毫秒的时候，有些帧中不包含任何PDCCH监听机会。因此，需要改进现有的3GPP标准规范中的寻呼机制，以确保UE能够正确定位寻呼PDCCH监听机会。In the design of the existing 3GPP 5G standard specification on the paging mechanism, if the ID of the paging search space indicated by the parameter pagingSearchSpace is a non-zero value, as described above, the paging PDCCH monitoring opportunity is determined from the A PDCCH monitoring opportunity starts. This requires that any PF contains at least one PDCCH monitoring opportunity. However, the requirements are not always satisfied under all parameter configurations. For example, when the period of the paging search space is greater than 10 milliseconds, some frames do not include any PDCCH monitoring opportunities. Therefore, it is necessary to improve the paging mechanism in the existing 3GPP standard specifications to ensure that the UE can correctly locate the paging PDCCH monitoring opportunity.

另外，在现有的3GPP 5G标准规范关于寻呼机制的设计中，UE可以认为同一个寻呼消息会使用小区中所有实际传输的波束(即所述S个传输波束)各传输一次。这是因为，对处于RRC_IDLE状态或者RRC_INACTIVE状态的UE，基站并不知道UE为接收寻呼所确定的传输波束(即所对应的SSB索引)是S个传输波束中的哪一个。问题是，在现有寻呼机制的设计中，有时候寻呼消息却并不总是能够用所有S个波束各传输一次。例如，若参数pagingSearchSpace所指示的寻呼搜索空间的ID是一个非0值，如前所述，每个PO中包含S个连续的寻呼PDCCH监听机会，其中第K个寻呼PDCCH监听机会使用小区中第K个实际传输的SSB的传输波束。另一方面，有些基站在每个符号上只支持一个传输波束，对于这些基站，若所述S个连续的寻呼PDCCH监听机会中的一个(假设对应SSB索引k)在时间上和索引为j的SSB重叠(即至少有一个符号重叠)，且k≠j，则在两者重叠的符号上，基站无法支持同时发送相应的PDCCH和SSB。图8显示了一个这样的例子，其中k＝8，j＝0。In addition, in the design of the existing 3GPP 5G standard specification regarding the paging mechanism, the UE may assume that the same paging message will be transmitted once using all actually transmitted beams (that is, the S transmission beams) in the cell. This is because, for the UE in the RRC_IDLE state or the RRC_INACTIVE state, the base station does not know which of the S transmission beams the transmission beam (ie, the corresponding SSB index) determined by the UE for receiving paging is. The problem is that in the design of existing paging mechanisms, sometimes paging messages are not always able to be transmitted once with all S beams. For example, if the ID of the paging search space indicated by the parameter pagingSearchSpace is a non-zero value, as described above, each PO contains S consecutive paging PDCCH monitoring opportunities, of which the Kth paging PDCCH monitoring opportunity is used The transmission beam of the Kth actually transmitted SSB in the cell. On the other hand, some base stations support only one transmission beam per symbol. For these base stations, if one of the S consecutive paging PDCCH monitoring opportunities (assuming corresponding SSB index k) is in time and index j SSB overlaps (that is, at least one symbol overlaps), and k ≠ j, on the symbols where the two overlap, the base station cannot support sending the corresponding PDCCH and SSB simultaneously. Figure 8 shows an example where k = 8 and j = 0.

因此，需要改进现有的3GPP标准规范中的寻呼机制，以确保在一个PO中能遍历小区中所有实际传输的SSB所对应的传输波束。Therefore, the paging mechanism in the existing 3GPP standard specification needs to be improved to ensure that the transmission beams corresponding to all actually transmitted SSBs in the cell can be traversed in one PO.

在步骤101，获取与寻呼有关的参数配置信息。In step 101, parameter configuration information related to paging is acquired.

其中，among them,

所述与寻呼有关的参数配置信息可以通过诸如基站发送的系统信息进行指示，也可以通过诸如基站发送的专用信令进行指示，也可以来自预定义信息或者预配置信息或者UE为接收寻呼而确定的其他配置信息，也可以通过从所述系统信息、所述专用信令、所述预定义信息、所述预配置信息、所述UE为接收寻呼而确定的其他配置信息的一个或多个中推导得到。The parameter configuration information related to paging may be indicated by system information such as sent by the base station, or may be indicated by dedicated signaling such as sent by the base station, or may be from pre-defined information or pre-configured information or the UE receives paging The other determined configuration information may also be selected from one of the system information, the dedicated signaling, the predefined information, the pre-configuration information, and other configuration information determined by the UE to receive paging or Derived from multiple.

所述与寻呼有关的参数配置信息可以包括如下中的一项或多项：The parameter configuration information related to paging may include one or more of the following:

●参考传输波束。例如，UE为接收寻呼而确定的一个参考传输波束。所述参考传输波束可以通过SSB索引指示。所述SSB索引可以是UE在获取MIB或者SIB1时所接收的SSB的索引，也可以是基站实际传输的其他SSB的索引。● Reference transmission beam. For example, a reference transmission beam determined by the UE for receiving paging. The reference transmission beam may be indicated by an SSB index. The SSB index may be an index of the SSB received by the UE when acquiring the MIB or SIB1, or an index of other SSBs actually transmitted by the base station.

●寻呼搜索空间配置信息。例如，通过参数pagingSearchSpace配置的寻呼搜索空间。● Paging search space configuration information. For example, the paging search space configured through the parameter pagingSearchSpace.

●寻呼控制信道配置信息。● Paging control channel configuration information.

●UE特定的DRX配置信息。● UE specific DRX configuration information.

●UE标识符(记为UE_ID)。例如，根据参数5G-S-TMSI确定的UE标识符，如UE_ID＝5G-S-TMSI mod 1024。● UE identifier (denoted as UE_ID). For example, the UE identifier determined according to the parameter 5G-S-TMSI, such as UE_ID = 5G-S-TMSI mod1024.

其中，among them,

所述寻呼控制信道配置信息可以通过PCCH-Config IE进行指示。所述PCCH-Config IE中可以包含诸如以下参数中的一个或多个：The paging control channel configuration information may be indicated through PCCH-ConfigIE. The PCCH-Config IE may contain one or more of the following parameters:

●缺省的寻呼周期，记为T_default。例如，通过参数defaultPagingCycle进行配置。● The default paging cycle is recorded as T_default. For example, the parameter defaultPagingCycle is used for configuration.

●DRX周期内的PF的个数，记为N。例如，通过参数nAndPagingFrameOffset进行配置。● The number of PFs in the DRX cycle is denoted as N. For example, the parameter nAndPagingFrameOffset is used for configuration.

●PF偏移，记为PF_offset。例如，通过参数nAndPagingFrameOffset进行配置。● PF offset, recorded as PF_offset. For example, the parameter nAndPagingFrameOffset is used for configuration.

●每个PF所对应的PO的个数，记为Ns。例如，通过参数ns进行配置。● The number of POs corresponding to each PF is recorded as Ns. For example, the parameter ns is used for configuration.

所述UE特定的DRX配置信息可以包含UE特定的DRX周期(或者说DRX值)。The UE-specific DRX configuration information may include a UE-specific DRX cycle (or DRX value).

所述UE特定的DRX配置信息可以通过RRC信令进行指示，也可以通过高层(例如NAS层)信令进行指示。The UE-specific DRX configuration information may be indicated through RRC signaling, or may also be indicated through higher layer (eg, NAS layer) signaling.

在步骤102，根据所述与寻呼有关的参数配置信息，确定DRX周期(记为T)。例如，若配置了UE特定的DRX值，则T由所述UE特定的DRX值和系统信息中广播的缺省DRX值(例如所述缺省的寻呼周期T_default)中的最小(或者说最短)的值确定。又如，若未配置UE特定的DRX值，则T由所述缺省DRX值确定。In step 102, according to the paging-related parameter configuration information, a DRX cycle (denoted as T) is determined. For example, if a UE-specific DRX value is configured, T is the smallest (or shortest) of the UE-specific DRX value and the default DRX value broadcast in the system information (eg, the default paging cycle T_default) ) Is determined. For another example, if the UE-specific DRX value is not configured, T is determined by the default DRX value.

在步骤103，根据所述与寻呼有关的参数配置信息，以及所述DRX周期，确定PF。例如，所述PF的帧号(记为SFN)可以通过如下方式之一得到：In step 103, the PF is determined according to the paging-related parameter configuration information and the DRX cycle. For example, the frame number of the PF (denoted as SFN) can be obtained in one of the following ways:

在步骤104，根据所述与寻呼有关的参数配置信息，和/或所述DRX周期，和/或所述PF，确定其他与寻呼有关的参数。In step 104, according to the paging-related parameter configuration information, and / or the DRX cycle, and / or the PF, determine other paging-related parameters.

例如，确定与寻呼PDCCH监听机会有关的信息。例如，将满足寻呼条件的PDCCH监听机会确定为寻呼PDCCH监听机会。其中，所述寻呼条件可以是下面中的一个或多个(按“与”或“或”的方式任意组合)：For example, the information related to the paging PDCCH monitoring opportunity is determined. For example, the PDCCH monitoring opportunity meeting the paging condition is determined as the paging PDCCH monitoring opportunity. Wherein, the paging condition may be one or more of the following (arbitrarily combined according to "AND" or "OR"):

●不和上行符号重叠。● Do not overlap with the upstream symbol.

又如，确定PO。例如，所述PO的编号(i_s)可以通过下式计算得到：As another example, determine PO. For example, the PO number (i_s) can be calculated by the following formula:

i_s＝floor(UE_ID/N)mod Nsi_s = floor (UE_ID / N) mod Ns

且所述UE监听第(i_s+1)个PO。And the UE monitors the (i_s + 1) th PO.

又如，确定PO中包含的连续的寻呼PDCCH监听机会。例如，所述“PO中包含的连续的寻呼PDCCH监听机会”的个数(S)可以等于实际传输的SSB的个数(例如通过SIB1中的参数ssb-PositionsInBurst进行指示)。又如，若参数firstPDCCH-MonitoringOccasionOfPO已配置，则第(i_s+1)个PO起始于参数firstPDCCH-MonitoringOccasionOfPO所指示的寻呼PDCCH监听机会，否则第(i_s+1)个PO起始于编号为(i_s*S)的寻呼PDCCH监听机会。In another example, the continuous paging PDCCH monitoring opportunities included in the PO are determined. For example, the number (S) of the "continuous paging PDCCH monitoring opportunities included in the PO" may be equal to the number of SSBs actually transmitted (for example, indicated by the parameter ssb-PositionsInBurst in SIB1). For another example, if the parameter firstPDCCH-MonitoringOccasionOfPO is configured, the (i_s + 1) PO starts with the paging PDCCH monitoring opportunity indicated by the parameter firstPDCCH-MonitoringOccasionOfPO, otherwise the (i_s + 1) PO starts with the number (i_s * S) paging PDCCH monitoring opportunities.

例如，可以根据图1所示的流程图中的步骤104确定PO的编号。也可以按其他方式确定PO的编号，本发明对此不做限定。For example, the number of the PO can be determined according to step 104 in the flowchart shown in FIG. 1. The number of the PO can also be determined in other ways, which is not limited in the present invention.

又如，可以根据实施例一所示的方法确定寻呼PDCCH监听机会及其编号。也可以按其他方式确定寻呼PDCCH监听机会及其编号，本发明对此不做限定。For another example, the paging PDCCH monitoring opportunity and its number can be determined according to the method shown in the first embodiment. The paging PDCCH monitoring opportunity and its number may also be determined in other ways, which is not limited in the present invention.

又如，可以根据图1所示的流程图中的步骤104确定PO中包含的连续的寻呼PDCCH监听机会。也可以按其他方式确定PO中包含的连续的寻呼PDCCH监听机会，本发明对此不做限定。As another example, the continuous paging PDCCH monitoring opportunities included in the PO may be determined according to step 104 in the flowchart shown in FIG. 1. The continuous paging PDCCH monitoring opportunities included in the PO may also be determined in other ways, which is not limited in the present invention.

又如，在所述PO中，若某个寻呼PDCCH监听机会(记其编号为i，下面称为寻呼PDCCH监听机会i)和某个实际传输的SSB(记其索引为 j，下面称为SSB j。可选地，实际传输的SSB也可以采用其他标识，例如一个从0开始的、按SSB索引递增的顺序进行编号的整数，例如，实际传输的SSB为SSB索引0和SSB索引32，分别编号为0和1。)的符号重叠(例如，至少在一个符号上重叠)，则所述寻呼PDCCH监听机会i可以对应所述SSB j。记所述和实际传输的SSB的符号重叠的寻呼PDCCH监听机会的个数为M(其中0≤M≤S)。例如，S＝8，M＝2，寻呼PDCCH监听机会1和SSB 0的符号重叠，寻呼PDCCH监听机会4和SSB 32的符号重叠，则寻呼PDCCH监听机会1对应SSB 0，寻呼PDCCH监听机会4对应SSB 32。对于其余(S-M)个寻呼PDCCH监听机会以及其余(S-M)个实际传输的SSB，从寻呼PDCCH监听机会到实际传输的SSB的对应关系可以是下面的一种：As another example, in the PO, if a certain paging PDCCH monitoring opportunity (denoted by its number i, hereinafter referred to as paging PDCCH monitoring opportunity i) and an actual transmitted SSB (denoted by its index is j, hereinafter referred to as It is SSB. Alternatively, the actual SSB transmitted can also use other identifiers, such as an integer starting from 0 and numbered in order of increasing SSB index, for example, the actual SSB transmitted is SSB index 0 and SSB index 32 , Symbols numbered 0 and 1, respectively.) If the symbols overlap (for example, at least one symbol overlaps), then the paging PDCCH monitoring opportunity i may correspond to the SSB j. It is noted that the number of paging PDCCH monitoring opportunities overlapping with the actual transmitted SSB symbol is M (where 0≤M≤S). For example, S = 8, M = 2, paging PDCCH monitoring opportunity 1 and SSB 0 symbols overlap, paging PDCCH monitoring opportunity 4 and SSB 32 symbols overlap, then paging PDCCH monitoring opportunity 1 corresponds to SSB 0, paging PDCCH Monitoring opportunity 4 corresponds to SSB 32. For the remaining (S-M) paging PDCCH monitoring opportunities and the remaining (S-M) actually transmitted SSBs, the corresponding relationship from the paging PDCCH monitoring opportunities to the actually transmitted SSBs can be one of the following:

●按照寻呼PDCCH监听机会的编号递增的顺序以及实际传输的SSB的编号(或者实际传输的SSB的索引)递增的顺序。例如，若所述(S-M)个寻呼PDCCH监听机会的编号依次是0、2、3、5、6、7，而所述(S-M)个实际传输的SSB的索引依次是8、16、24、40、48、56，则寻呼PDCCH监听机会0对应SSB 8，寻呼PDCCH监听机会2对应SSB 16，寻呼PDCCH监听机会3对应SSB 24，寻呼PDCCH监听机会5对应SSB 40，寻呼PDCCH监听机会6对应SSB 48，寻呼PDCCH监听机会7对应SSB 56。● According to the order of increasing the number of paging PDCCH monitoring opportunities and the order of the actually transmitted SSB (or the index of the actually transmitted SSB). For example, if the numbers of the (SM) paging PDCCH monitoring opportunities are 0, 2, 3, 5, 6, 7, and the (SM) actually transmitted SSB indexes are 8, 16, 24, respectively. , 40, 48, 56, then paging PDCCH monitoring opportunity 0 corresponds to SSB 8, paging PDCCH monitoring opportunity 2 corresponds to SSB 16, paging PDCCH monitoring opportunity 3 corresponds to SSB 24, paging PDCCH monitoring opportunity 5 corresponds to SSB 40, paging PDCCH monitoring opportunity 6 corresponds to SSB 48, and paging PDCCH monitoring opportunity 7 corresponds to SSB 56.

●按照寻呼PDCCH监听机会的编号递增的顺序以及实际传输的SSB的编号(或者实际传输的SSB的索引)递减的顺序。例如，若所述(S-M)个寻呼PDCCH监听机会的编号依次是0、2、3、5、6、7，而所述(S-M)个实际传输的SSB的索引依次是8、16、24、40、48、56，则寻呼PDCCH监听机会0对应SSB 56，寻呼PDCCH监听机会2对应SSB 48，寻呼PDCCH监听机会3对应SSB 40，寻呼PDCCH监听机会5对应SSB 24，寻呼PDCCH监听机会6对应SSB 16，寻呼PDCCH监听机会7对应SSB 8。● In order of increasing number of paging PDCCH monitoring opportunities and decreasing order of actually transmitted SSB number (or index of actually transmitted SSB). For example, if the numbers of the (SM) paging PDCCH monitoring opportunities are 0, 2, 3, 5, 6, 7, and the (SM) actually transmitted SSB indexes are 8, 16, 24, respectively. , 40, 48, 56, then paging PDCCH monitoring opportunity 0 corresponds to SSB 56, paging PDCCH monitoring opportunity 2 corresponds to SSB 48, paging PDCCH monitoring opportunity 3 corresponds to SSB 40, paging PDCCH monitoring opportunity 5 corresponds to SSB 24, paging PDCCH monitoring opportunity 6 corresponds to SSB 16, and paging PDCCH monitoring opportunity 7 corresponds to SSB 8.

●通过高层信令(例如RRC信令)指示从寻呼PDCCH监听机会到实际传输的SSB的对应关系。例如，所述RRC信令指示为按照寻呼PDCCH监听机会的编号递增的顺序以及实际传输的 SSB的编号(或者实际传输的SSB的索引)递增的顺序。又如，所述RRC信令指示为按照寻呼PDCCH监听机会的编号递增的顺序以及实际传输的SSB的编号(或者实际传输的SSB的索引)递减的顺序。● Instruct the corresponding relationship from the paging PDCCH monitoring opportunity to the actually transmitted SSB through high layer signaling (eg RRC signaling). For example, the RRC signaling indication is in the order of increasing number of paging PDCCH monitoring opportunities and the order of actually transmitted SSB number (or index of actually transmitted SSB). For another example, the RRC signaling indication is in order of increasing number of paging PDCCH monitoring opportunities and decreasing order of actually transmitted SSB number (or index of actually transmitted SSB).

●通过其他方式确定的从寻呼PDCCH监听机会到实际传输的SSB的对应关系。● The correspondence relationship between the paging PDCCH monitoring opportunity and the actually transmitted SSB determined by other methods.

可选地，本发明的实施例三中，若所述UE处于RRC_CONNECTED状态，则对于与寻呼有关的参数配置信息(例如，某个参数是否已配置，和/或该参数所配置的值是什么，等等)，专用信令的指示可以覆盖系统信息如SIB1的指示。Optionally, in the third embodiment of the present invention, if the UE is in the RRC_CONNECTED state, then the parameter configuration information related to paging (for example, whether a parameter has been configured, and / or the value configured by the parameter is What, etc.), the indication of dedicated signaling can override the indication of system information such as SIB1.
