- the UE does not receive downlink channels and signals such as PDCCH to reduce power consumption.
- a UE in RRC idle (IDLE) state needs to receive paging messages in a similar manner to DRX.

- the energy saving signal is introduced.
- the energy-saving signal is used in combination with the DRX mechanism, and the terminal receives the indication of the energy-saving signal before DRX On Duration.
- the power-saving signal may also be referred to as a power-saving wake-up signal.
- the power-saving signal When the terminal has data transmission in one DRX cycle, the power-saving signal "wakes up" the terminal to monitor the PDCCH during the DRX On duration. Otherwise, when the terminal has no data transmission in a DRX cycle, the energy-saving signal does not "wake up” the terminal, and the terminal does not need to monitor the PDCCH during the DRX On Duration.
- the terminal when the terminal has no data transmission, the terminal can omit PDCCH monitoring during the DRX On duration, thereby achieving energy saving.
- the time when the terminal is outside the DRX On duration is called the inactive time, and the time in the DRX On Duration is called the active time.

- the power saving signal may carry multi-user power saving indication information.
- the network informs each user of the starting position of the energy-saving indication bits in the DCI, and the number of bits for a single user can be implicitly obtained by the configured number of secondary cell (carrier) groups (the wake-up indication bit must appear, and the secondary cell (carrier) is dormant.
- the number of indication bits may be 0). Further, the network will also notify the terminal of the total number of bits of DCI and the PS (Power Saving, energy saving signal)-RNTI of the scrambled PDCCH.
- the network configures a time offset (eg PS-offset) for determining the starting point of the PDCCH listening occasion. After the starting point of the PDCCH monitoring occasion is determined, the end point of the PDCCH monitoring needs to be further determined.
- the end point of PDCCH monitoring may be determined by the device capability of the terminal.
- the terminal needs to perform operations such as device wake-up and initialization after wake-up within the minimum time interval before DRX ON. Therefore, the terminal does not need to monitor the energy-saving signal within the minimum time interval before DRX ON.
- a terminal with a faster processing speed can use a shorter minimum time interval, see value 1 in Table 1, while a terminal with a slower processing speed needs to use a longer minimum time interval, see value 2 in Table 1.
- the energy-saving signal starts from the time position indicated by the PS-offset configured by the network, and monitors the energy-saving signal within a complete PDCCH search space period (for example, defined by the parameter "duration" of the PDCCH search space) after the starting point, and the monitored The position of the power saving signal is before the time period corresponding to the minimum time interval. As shown in FIG. 4 , the terminal monitors the monitoring timing of the energy-saving signal indicated by the dotted box.
- the network can send pages to UEs in idle (IDLE) state and connected (RRC-CONNECTION) state.
- the paging process can be triggered by the core network or the base station, and is used to send a paging request to the UE in an idle state, or to notify the system to update the information, or to notify the UE to receive the Earthquake and Tsunami Warning System (ETWS) And commercial mobile alert service (Commercial Mobile Alert System, CMAS) and other information.
- EWS Earthquake and Tsunami Warning System
- CMAS commercial mobile alert service
- the base station interprets the content, obtains the tracking area identification (Tracking Area Identity, TAI) list (list) of the UE, and performs air interface calls in the cells belonging to the tracking area in the list. paging.
- TAI Track Area Identity
- the core network domain of the paging message will not be decoded by the base station, but will be transparently transmitted to the UE.
- the base station After receiving the paging message of the core network, the base station aggregates the paging messages of the UEs with the same PO (paging occasion, paging occasion) into a paging message, and transmits it to the relevant UE through the paging channel.
- the UE receives the paging parameters through the system message, calculates the PO in combination with its own UE_ID, and receives the paging message at the corresponding time.
- the paging message is carried through the Physical Downlink Shared Channel (PDSCH).
- PDSCH Physical Downlink Shared Channel
- the UE obtains the paging indication information by detecting the PDCCH scrambled with the P-RNTI, thereby receiving the paging message.
- the UE in the idle state will save power by means of DRX, and the UE obtains DRX-related information from SIB2 (System Information Blocks 2, system message 2).
- SIB2 System Information Blocks 2, system message 2.
- the UE receives the paging message by monitoring the PDCCH scrambled by the P-RNTI at the PO on the PF (Paging Frame, paging frame) in one DRX cycle.
- PF indicates which system frame number the paging message should appear on, and PO indicates the time when it may appear.
- a PF frame may include one or more POs.
- SFN system frame number
- the index (index) of the PO corresponding to the UE_ID, that is, i_s can be calculated according to the following formula.
- i_s floor(UE_ID/N)mod Ns
- UE_ID (5G-S-TMSI mod 1024).
- N is the number of PFs in T. Ns is the number of POs in a PF.
- PF_offset is the frame offset used to determine the PF. For example, as shown in FIG. 5 , it is the position of the PF in one DRX cycle (cycle), and the position of the PO in the PF.
- SSB SS/PBCH block
- Common channels and signals in the NR system need to cover the entire cell by means of multi-beam scanning, which is convenient for UEs in the cell to receive.
- the multi-beam transmission of synchronization signal is realized by defining the SS/PBCH burst set (burst set).
- An SS/PBCH burst set contains one or more SS/PBCH blocks.
- One SS/PBCH block is used to carry the synchronization signal and broadcast channel of one beam. Therefore, an SS/PBCH burst set can contain synchronization signals for up to L beams in a cell.
- L is related to the frequency band of the system, for example:
- L When the frequency range is up to 3GHz (gigahertz), L is 4 (For frequency range up to 3GHz, Li is 4);
- An SS/PBCH block contains a primary synchronization signal (PSS) of one symbol, an SSS of one symbol and a PBCH (Physical broadcast channel) of two symbols.
- the time-frequency resources occupied by the PBCH include a demodulation reference signal (Demodulation Reference Signal, DMRS), which is used for demodulation of the PBCH.
- DMRS Demodulation Reference Signal
- all SS/PBCH blocks in the SS/PBCH burst set are sent within a time window of 5ms (milliseconds) and are sent repeatedly with a certain period.

- an indication method for controlling the energy saving information received by paging is provided, an example of which is as follows:
- Example 1 The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is configured through the network
- the UE When the UE is in the RRC idle or RRC inactive state, it can determine the monitoring timing to detect the PDCCH according to its own PF and PO, and can perform DRX at other times to save power. In order to further achieve the purpose of power saving, it is ideal that the UE can know in advance whether there will be a paging message sent to itself when each of its own POs arrives. If not, the UE may not perform PDCCH detection at the PO to achieve further power saving.
- a method for determining a time-domain resource location where an energy-saving signal is located is provided by taking an example of carrying an energy-saving signal through a sequence such as a reference signal sequence or a synchronization signal sequence.
- the power saving information can be implicitly indicated by the difference of the sequence.
- the power saving signal can indicate whether the UE monitors the paging message in the PF or PO.
- the UE When the UE is in the RRC idle or RRC inactive state, it needs to perform time-frequency synchronization before receiving the paging message. Since the UE in the RRC idle or RRC inactive state is not configured with UE-specific reference signals such as CSI-RS, the UE can only perform time-frequency synchronization based on the SSB.
- the UE generally needs to "wake up" in advance to start the time-frequency synchronization operation before its own PO.
- the UE performs time-frequency synchronization by detecting the SSB.
- the UE performs time-frequency synchronization by detecting the SSB.
- it depends on the implementation of the UE, for example, by receiving 1-3 SSB burst sets (burst sets) to restore time-frequency synchronization.
- Fig. 8 takes the UE's detection of the latest SSB burst set before PO as an example to illustrate the process of the UE detecting SSB before PO to perform time-frequency synchronization.
- the minimum time interval between the time domain resource where the energy-saving signal is located and before the DRX ON is determined by the device capability of the terminal.
- a terminal with a faster processing speed can use a shorter minimum time interval, see the value 1 in Table 1 of the above embodiment, while a terminal with a slower processing speed needs to use a longer minimum time interval, see Table 1. value 2.
- the minimum time interval is configured to the UE through the network.
- the network can determine the time gap time gap 1 according to the sending situation of the SSB, such as the period configuration, the timing relationship with the PO, etc., and indicate it to the UE.
- the UE After receiving the time interval indication information, the UE determines not to detect the energy saving signal in the time interval before the PO starts. For example, as shown in FIG. 9, the network configures the offsets PS-offset and PS-offset2.
- PS-offset is used to indicate the starting point of the time domain resource of the UE to detect the energy saving signal (that is, the starting point of the time interval)
- PS-offset2 is used to indicate the end point of the time domain resource of the UE detecting the energy saving signal (that is, the starting point of the time interval).
- the energy-saving signal is not detected within the time interval indicated by PS-offset2 (ie, time gap 1).
- the UE can recover time-frequency synchronization through the SSB to detect paging when the PO arrives.
- the energy saving signal indicates that paging is not to be detected at the PO, the UE may also not perform time-frequency synchronization recovery within the time interval.
- the unit of the time interval may be a time slot, a subframe, a symbol, a millisecond, a period of an SSB, or the like.
- the network instructs the time interval for not detecting the energy-saving signal before the PO or PF starts, so that the UE has enough time to perform time-frequency synchronization after receiving the energy-saving signal, and the network can flexibly according to the SSB transmission situation Configure this time interval.
- Example 2 The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is a predefined time interval.
- the minimum time interval before the DRX ON of the time domain resource where the energy-saving signal is located is determined by the device capability of the terminal. Referring to Table 1 of the above embodiment, this minimum time interval is relatively short. It is difficult for the UE to complete the time-frequency synchronization within this time interval.
- the minimum time interval between the time domain resource of the energy saving signal and the PO or PF may be predefined.
- the predefined value may not be determined according to the UE capability, but may be determined according to the requirement of completing the time-frequency synchronization recovery within the time interval. For example, assuming that the period of the SSB is predefined as 5ms, and the UE needs to receive 2 SSB burst sets to restore time-frequency synchronization, the minimum time interval can be predefined as 10ms. For the 15KHz subcarrier spacing, it is 10 time slots, as shown in Table 3.
- Subcarrier spacing kHz
- Minimum time interval slots 15 10 30 20 60 40 120 80
- the minimum time interval may have nothing to do with the processing capability of the UE, and the value can satisfy the processing capability of the UE, and only one set of values may be reserved in Table 3.
- This example uses a predefined method to determine the minimum time interval between the time domain resource of the energy-saving signal and the PO or PF, which can save signaling overhead and is simple to implement.
- Example 3 The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is determined according to a predefined rule.
- all SS/PBCH blocks in the SS/PBCH burst set are sent within a time window of 5ms, and are repeatedly sent with a certain period.
- the period can be configured through high-level parameters such as ssb-PeriodicityServingCell, including 5ms, 10ms, 20ms, 40ms, 80ms, 160ms and so on. This period can be obtained via system message SIB1.
- the UE may determine the minimum time interval between the time domain resources of the energy-saving signal and the PO or PF according to the period.
- the relationship between the minimum time interval and the transmission period of the SSB may be predefined.
- the predefined minimum time interval is N times the transmission period of the SSB, and N may be equal to 1, 2, 3, etc., depending on the number of SSBs that the UE needs to receive to complete the time-frequency synchronization recovery within the minimum time interval. In this way, the UE can determine the minimum time interval.
- T represents the transmission period of the SSB obtained by the UE from the system message or RRC signaling, in ms; and N is a predefined coefficient. According to Table 2, the minimum time interval under different subcarrier intervals is obtained, and the unit is time slot.
- the minimum time interval is determined according to the transmission period of the SSB, which can ensure a desired number of SSBs within the time interval for the UE to perform time-frequency synchronization recovery. Compared with the predefined minimum time interval, it has certain flexibility.
- the UE can have enough time to perform time-frequency synchronization after receiving the energy-saving signal, so as to correctly receive the paging during the PO period. .

为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
DRX的机制包括为处于无线资源控制(Radio Resource Control,RRC)连接(CONNECTED)状态的UE配置DRX周期(cycle)。一个DRX cycle包括“On Duration(开启持续)”和“Opportunity for DRX(DRX机会)”。在“On Duration”时间内,UE监听并接收包括物理下行控制信道(Physical Downlink Control Channel,PDCCH)在内的下行信道和信号。在“Opportunity for DRX”时间内,UE不接收PDCCH等下行信道和信号,以减少功耗。在RRC空闲(IDLE)状态下的UE需要采用与DRX类似的方式接收寻呼消息。在一个DRX周期内存在一个寻呼时机(PO),UE只在PO接收寻呼消息,而在PO之外的时间不接受寻呼消息,来达到省电的目的。在PO期间,UE通过检测通过P-RNTI(Paging-Radio Network Temporary Identity,寻呼-无线网络临时标识)加扰的PDCCH信号来判断是否有寻呼消息。
在5G的演进中,对UE节电提出了更高的要求。例如对于DRX机制,在每个On Duration期间,UE需要不断检测PDCCH来判断基站是否调度发给自己的数据传输。但是对于大部分UE来说,可能在很长一段时间没有接收数据传输的需要,但是仍然需要保持定期的唤醒机制来监听可能的下行传输,对于这类UE,节电有进一步优化的空间。对于RRC IDLE状态下的UE接收寻呼消息的情况也是类似。
为了进一步实现节能,引入了节能信号。节能信号与DRX机制结合使用,终端在DRX On Duration之前接收节能信号的指示。示例性地,节能信号也可以称为节能唤醒信号。当终端在一个DRX周期有数据传输时,节能信号“唤醒”终端,以在DRX On duration期间监听PDCCH。否则,当终端在一个DRX周期没有数据传输时,节能信号不“唤醒”终端,终端在DRX On Duration期间不需要监听PDCCH。相比单一的DRX机制,在终端没有数据传输时,终端可省略DRX On duration期间PDCCH监听,从而实现节能。终端在DRX On duration之外的时间被称为非激活时间,在DRX On Duration的时间被称为激活时间。通过节能信号指示终端在DRX On Duration是否监听PDCCH的过程,如图2所示。
示例性地,节能信号可以通过DCI format 2_6承载。网络配置终端检测承载DCI format 2_6的PDCCH的搜索空间集合(search space set)。例如,在节能信号中,单个用户所需的 比特数目为最多6个。其中包括1个唤醒指示比特和最多5个辅小区休眠指示比特。节能信号携带多个用户的指示比特以提升资源使用效率。如图3所示,节能信号可以承载多用户节能指示信息。网络通知每一个用户的节能指示比特在DCI中的起始位置,而单用户的比特数目可通过配置的辅小区(载波)分组数目隐式得到(唤醒指示比特一定出现,辅小区(载波)休眠指示比特数目可以为0)。进一步地,网络还会通知终端DCI的总比特数目以及加扰PDCCH的PS(Power Saving,节能信号)-RNTI。
该PDCCH的监听时机与DRX On Duration(可以简称DRX ON)的时间窗口之间有一定的定时关系。网络配置一个时间偏移(例如PS-offset),用于确定PDCCH监听时机的起始点。在确定PDCCH监听时机的起点之后,还需要进一步确定PDCCH监听的终点。PDCCH监听的终点可以是由终端的设备能力所确定的。终端在DRX ON之前的最小时间间隔内需要执行设备唤醒以及唤醒后的初始化等操作,因此,在DRX ON之前的最小时间间隔内终端不需要监听节能信号。处理速度较快的终端,可以使用较短的最小时间间隔,见下表1中的值1,而处理速度较慢的终端,需要使用较长的最小时间间隔,见表1中的值2。
表1最小时间间隔
节能信号以网络配置的PS-offset指示的时间位置为起点,在该起点后一个完整的PDCCH搜索空间周期内(例如,由PDCCH搜索空间的参数“duration”定义)监听节能信号,且所监听的节能信号的位置在最小时间间隔所对应的时间段之前。如图4所示,终端监听虚线框所标示的节能信号的监听时机。
在NR***中,网络可以向空闲(IDLE)状态和连接(RRC-CONNECTION)状态的UE发送寻呼。寻呼过程可以由核心网触发或者基站触发,用于向处于空闲态的UE发送寻呼请求,或者用于通知***信息更新,或者通知UE接收地震海啸预警信息(Earthquake and Tsunami Warning System,ETWS)以及商用移动预警服务(Commercial Mobile Alert System,CMAS)等信息。基站接收到核心网的寻呼消息后,解读其中的内容,得到该UE的跟踪区域标识(Tracking Area Identity,TAI)列表(list),并在其下属于列表中的跟踪区域的小区进行空口的寻呼。寻呼消息的核心网域不会在基站解码,而是透传给UE。基站收到核心网的寻呼消息之后,将PO(paging occasion,寻呼时机)相同的UE的寻呼消息汇总成一条寻呼消息,通过寻呼信道传输给相关UE。UE通过***消息接收寻呼参数,结合自身UE_ID计算PO,在相应的时间接收寻呼消息。寻呼消息通过物理下行共享信道(Physical Downlink Shared Channel,PDSCH)承载。UE通过检测用P-RNTI加扰的PDCCH获得寻呼指示信息,从而接收寻呼消息。空闲态的UE会通过DRX的方式省电,UE从SIB2(System Information Blocks 2,***消息2)获取DRX相关信息。UE在一个DRX周期中的PF(Paging Frame,寻呼帧)上的PO监听通过P-RNTI加扰的PDCCH来接收寻呼消息。
PF表示寻呼消息应该出现在哪个***帧号上,PO则表示可能出现的时刻。一个PF帧可能包括1个或多个PO。每个DRX周期或者寻呼周期(Paging Cycle),UE只需要监听其中属于自己的PO。满足下面公式的***帧号(System Frame Number,SFN)即可作为一个PF:
(SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)
在PF内,可以根据下面公式计算UE_ID对应的PO的索引(index),即i_s。
i_s=floor(UE_ID/N)mod Ns
在上述公式中,SFN为***帧号,UE_ID为UE标识。mod表示取模运算,div表示整除运算。floor()表示向下取整。T表示UE的DRX周期。如果将***消息中指示的默认DRX周期记为T_sib的话,并且如果已经配置了UE的DRX值T_ue,则T=min(T_ue,T_sib);如果没有配置T_ue,则使用***消息中指示的默认值T=T_sib。UE_ID=(5G-S-TMSI mod 1024)。N为T内的PF的个数。Ns为一个PF内的PO的个数。PF_offset为用于确定PF的帧偏移。例如,如图5所示,为在一个DRX周期(cycle)内的PF的位置,以及PF内PO的位置。
下面介绍NR的SS/PBCH block(SSB)传输:
在NR***中的公共信道和信号,如同步信号和广播信道,需要通过多波束扫描的方式覆盖整个小区,便于小区内的UE接收。同步信号(SS,synchronization signal)的多波束发送是通过定义SS/PBCH突发集合(burst set)实现的。一个SS/PBCH burst set包含一个或多个SS/PBCH block。一个SS/PBCH block用于承载一个波束的同步信号和广播信道。因此,一个SS/PBCH burst set可以包含小区内最多L个波束的同步信号。L与***的频段有关,例如:
频率范围高达3GHz(千兆赫)时,L为4(For frequency range up to 3GHz,L is 4);
频率范围从3GHz到6GHz,L为8(For frequency range from 3GHz to 6GHz,L is 8);
频率范围从6GHz到52.6GHz,L为64(For frequency range from 6GHz to 52.6GHz,L is 64)
一个SS/PBCH block(SSB)中包含一个符号的主同步信号(Primary Synchronization Signal,PSS),一个符号的SSS和两个符号的PBCH(Physical broadcast channel,物理广播信道)。其中,PBCH所占的时频资源中,包含解调参考信号(Demodulation Reference Signal,DMRS),用于PBCH的解调。
例如,SS/PBCH burst set内所有的SS/PBCH block在5ms(毫秒)的时间窗内发送,并以一定的周期重复发送。周期可以通过高层的参数例如:ssb-PeriodicityServingCell(SSB周期服务单元)进行配置,周期可以包括5ms,10ms、20ms、40ms、80ms、160ms等。
目前的节能信号,需要满足以网络配置的节能信号偏移(PS-offset)指示的时间位置为起点,在该起点后一个完整的PDCCH搜索空间周期内(由PDCCH搜索空间的参数“duration”定义)监听节能信号,且所监听的节能信号的位置与DRX On duration起始位置 的间隔需要满足最小时间间隔。该最小时间间隔只需要考虑UE的处理能力即可,不需要考虑UE由于在DRX On duration到达之前进行时频同步,以便于DRX On duration期间能够正确地接收PDCCH。这是因为,对于连接态的UE,可以通过配置的CSI-RS(Channel-State Information Reference Signal,信道状态信息参考信号)、TRS(Time Reference Signal,时间参考信号)等参考信号进行时频同步。对于空闲态的UE,节能信号可以用于指示UE是否在达到的PO上接收寻呼。由于空闲态的UE没有被配置CSI-RS、TRS等参考信号,只能利用周期发送的(Synchronization Signal,同步信号)/PBCH(Physical Broadcast Channel,物理广播信道)块(block)(简称SSB(同步信号块))进行时频同步。目前的最小时间间隔并不能满足在PO到达之前通过SSB进行时频同步的目的,导致不能正确地接收寻呼。

本实施例的网络设备执行方法300的具体示例可以参见上述方法200的中关于网络设备例如基站的相关描述,为了简洁,在此不再赘述。
在本申请实施例中,提供了用于控制寻呼接收的节能信息的指示方法,示例如下:
示例1:节能信号的时域资源与PO或PF之间的最小时间间隔通过网络配置
当UE处于RRC idle或RRC inactive状态时,可以根据自己的PF和PO,确定检测 PDCCH的监听时机,在其他时间可以进行DRX,以达到节电的目的。为了进一步达到节电的目的,比较理想的是UE可以在每个自己的PO到达的时候提前知道是否会有发给自己的寻呼消息。如果没有,UE就可以在该PO不进行PDCCH的检测,以达到进一步的省电。
本示例中,以通过序列例如参考信号序列或者同步信号序列等承载节能信号为例,提供一种确定节能信号所在的时域资源位置的方法。通过序列的不同可以隐含地指示节能信息。通过节能信号可以指示UE是否在PF或者PO监听寻呼消息。当UE处于RRC idle或RRC inactive状态时,在接收寻呼消息之前需要进行时频同步。由于RRC idle或RRC inactive状态下的UE没有被配置UE特定的参考信号如CSI-RS,UE只能基于SSB进行时频同步。因此,UE在自己的PO之前,一般需要提前“醒来”开始进行时频同步操作。UE在PO到达之前,通过检测SSB进行时频同步。至于UE需要提前多长时间、检测几个周期的SSB来达到时频同步,取决于UE的实现,例如通过接收1-3个SSB突发集合(burst set)来恢复时频同步。图8以UE对在PO之前最近的SSB突发集合进行检测为例,说明UE在PO之前检测SSB进行时频同步的过程。
相关技术中,节能信号所在的时域资源距离DRX ON之前的最小时间间隔是由终端的设备能力所确定的。处理速度较快的终端,可以使用较短的最小时间间隔,参见上述实施例的表1中的值1,而处理速度较慢的终端,需要使用较长的最小时间间隔,见表1中的值2。
本示例中,该最小时间间隔通过网络配置给UE。网络可以根据SSB的发送情况,例如周期配置、与PO的定时关系等,确定该时间间隔time gap 1,并指示给UE。UE在收到该时间间隔指示信息,确定在PO开始前的该时间间隔内不检测节能信号。例如,如图9所示,网络配置偏移量PS-offset和PS-offset2。其中,PS-offset用于指示UE检测节能信号的时域资源的起点(也即时间间隔的起点),PS-offset2用于指示UE检测节能信号的时域资源的终点(也即时间间隔的起点),即在PS-offset2指示的时间间隔内(即time gap 1)不检测节能信号。在该时间间隔内,UE可以通过SSB进行时频同步的恢复,从而在PO到达时检测寻呼。当然,如果节能信号指示在PO不检测寻呼,则UE也可以在时间间隔内不进行时频同步的恢复。具体的,该时间间隔的单位可以是时隙、子帧、符号、毫秒或者SSB的周期等。
进一步的,结合由UE能力确定的最小时间间隔time gap 2,UE可以进一步确定出时间间隔time gap=Max{time gap 1,time gap 2},即在time gap 1和time gap 2之间取较大的时间间隔。这样既满足了UE的能力,又可以根据网络配置一个较长的时间间隔,用于UE在接收完节能信号之后有足够的时间进行时频同步。
在本示例中,通过网络指示PO或PF开始前不检测节能信号的时间间隔,可以使UE在接收完节能信号之后有足够的时间进行时频同步,并且,网络可以根据SSB的发送情况灵活地配置该时间间隔。
示例2:节能信号的时域资源与PO或PF之间的最小时间间隔为预定义的时间间隔。
相关技术中,节能信号所在的时域资源距离DRX ON之前的最小时间间隔是由终端的 设备能力所确定的。参见上述实施例的表1,这个最小时间间隔是比较短的。UE在这个时间间隔内完成时频同步很困难。
本示例中,节能信号的时域资源与PO或PF之间的最小时间间隔可以是预定义的。该预定义的值可以不是根据UE能力确定的,而是根据该时间间隔内完成时频同步恢复的要求来确定。例如,假设SSB的周期预定义为5ms,UE需要接收2个SSB burst set来恢复时频同步,那么该最小时间间隔可以预定义为10ms。对于15KHz子载波间隔来说就是10个时隙,如表3所示。
表3最小时间间隔
子载波间隔(kHz) | 最小时间间隔(slots) |
15 | 10 |
30 | 20 |
60 | 40 |
120 | 80 |
在本示例中,该最小时间间隔可以与UE的处理能力无关,且取值都是可以满足UE处理能力的,表3中可以只保留一组值。
本示例采用预定义的方式确定节能信号的时域资源与PO或PF之间的最小时间间隔,可以节省信令开销,实现简单。
示例3:节能信号的时域资源与PO或PF之间的最小时间间隔根据预定义的规则确定。
根据相关技术,SS/PBCH burst set内所有的SS/PBCH block在5ms的时间窗内发送,并以一定的周期重复发送。该周期可以通过高层的参数例如ssb-PeriodicityServingCell进行配置,包括5ms,10ms,20ms,40ms,80ms,160ms等。该周期可以通过***消息SIB1获得。
例如,UE获得SSB的传输周期后,可以根据该周期确定节能信号的时域资源与PO或PF之间的最小时间间隔。具体的,可以预定义该最小时间间隔与SSB的传输周期的关系。例如预定义最小时间间隔为SSB的传输周期的N倍,N可以等于1,2,3…,取决于UE在该最小时间间隔内完成时频同步恢复所需要接收的SSB的个数。通过这种方式,UE可以确定该最小时间间隔。参见上述实施例中的表2,T表示UE从***消息或者RRC信令中获得的SSB的传输周期,以ms为单位;N为预定义的系数。根据表2得到不同子载波间隔下的最小时间间隔,以时隙为单位。
在本示例中,根据SSB的传输周期确定最小时间间隔,可以保证时间间隔内有期望数量的SSB用于UE进行时频同步的恢复,相比预定义的最小时间间隔,具有一定的灵活性。
根据本申请实施例的确定PO和节能信号时域资源之间的最小时间间隔的方法,可以使UE在接收完节能信号之后有足够的时间进行时频同步,从而在PO期间正确地接收寻呼。
