- the synchronization signal block is used to complete AGC and time-frequency synchronization in the idle/inactive state, but in general, the transmission period of SSB is longer (for example, 20ms), and the UE needs to wake up earlier before receiving paging , and the UE may need to receive multiple SSBs for synchronization and AGC, so receiving SSBs consumes more energy.
- channel state information (CSI)-reference signal can be used for synchronization in connected state, CSI measurement, radio resource management (RRM) measurement, wireless link monitoring, beam failure detection, beam management, AGC, etc. , and the UE in the idle state (idle/inactive) cannot use the CSI-RS to complete these functions. Therefore, in order to reduce power consumption, a tracking reference signal (TRS)/CSI-RS is introduced in the radio resource control (RRC) idle/inactive state to assist in measurement, etc., thereby reducing power consumption overhead and realizing energy saving.
- RRC radio resource control
- TRS Since one TRS is composed of 4 CSI-RS resources, and the bandwidth configured by TRS is larger, compared with SSB, using TRS can achieve better time-frequency tracking.
- the UE can skip multiple SSBs if it uses TRS for synchronization before receiving paging under low SNR conditions. Assuming that TRS is not available in the idle/inactive state, the UE needs to use 3 SSBs for AGC, synchronization, RRM measurement, etc.
- the UE needs to wake up more than 40ms in advance; while in the idle/inactive state TRS available , assuming that the UE only needs one TRS and one SSB to complete AGC and synchronization before receiving paging, and generally, the TRS configuration is denser than that of the SSB, and the UE needs to wake up less than 40ms earlier, thereby bringing energy-saving gains.
- a system information block is introduced to carry the configuration of idle/inactive TRS/CSI-RS occasion(s), where the configuration information of TRS/CSI-RS occasion(s) contains one or more TRS resource sets , each TRS resource set contains a set of TRS resources.

- the modification period is used to update other SI messages except the SI messages related to the earthquake and tsunami warning system (ETWS), commercial mobile warning system (CMAS) and positioning assistance data, and is applied to UEs configured with DRX cycle.

- the UE After the UE receives the idle/inactive TRS/CSI-RS availability indication, the UE considers that the idle/inactive TRS/CSI-RS is always valid within the valid duration from the reference point, but one scenario is that during the valid duration Within the period, the configuration information of idle/inactive TRS/CSI-RS occasion(s) or the duration of the effective duration of the bearer may change. When this happens, how does the UE handle the idle/inactive TRS/CSI-RS valid sexual behavior is unclear.

本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术
语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。

例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备,其中,接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、WLAN接入点或WiFi节点等,基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例进行介绍,并不限定基站的具体类型。
工作在空闲态(idle)/非激活态(inactive)状态的UE,在接收寻呼之前需要进行自动增益控制(AGC)、时频同步等以保证可以正确的接收寻呼(paging)物理下行控制信道(PDCCH)/物理下行共享信道(PDSCH)。NR中在idle/inactive状态下使用同步信号块(SSB)完成AGC、时频同步,但一般情况下,SSB的传输周期较长(例如20ms),UE在接收寻呼之前需要更早地醒来,且UE可能需要接收多个SSB进行同步、AGC,从而接收SSB消耗的能量较多。
相关技术中,信道状态信息(CSI)-参考信号(RS)可以用于连接态下的同步,CSI测量,无线资源管理(RRM)测量,无线链路监测,波束失败检测,波束管理,AGC等,而空闲态(idle/inactive)下的UE无法使用CSI-RS完成这些功能。因此为了降低功耗,在无线资源控制(RRC)idle/inactive态中引入跟踪参考信号(TRS)/CSI-RS来辅助进行测量等,从而降低功耗开销,实现节能。
由于一个TRS是由4个CSI-RS资源构成的,且TRS配置的带宽更大,因此相比于SSB来说,使用TRS可以取得更好的时频跟踪。当idle/inactive状态的TRS可用时,UE在低信噪比情况下接收寻呼之前如果使用了TRS进行同步,可以跳过多个SSB。假设在idle/inactive状态下的TRS不可用时,UE在寻呼机会(PO)之前需要使用3个SSB进行AGC、同步、RRM测量等,UE需要提前大于40ms时间醒来;而在idle/inactive状态下的TRS可用
时,假设UE在接收寻呼之前只需要一个TRS和一个SSB完成AGC、同步,且一般情况下,TRS配置相比于SSB密集,UE需要提前少于40ms时间醒来,从而带来节能增益。
相关技术中,引入一个系统信息块(SIB)来承载idle/inactive TRS/CSI-RS occasion(s)的配置,其中TRS/CSI-RS occasion(s)的配置信息包含一个或者多个TRS resource sets,每个TRS resource set包含一组TRS resources。
关于idle/inactive UE的可用性,目前已经同意支持paging PDCCH based availability指示信息和PEI based availability指示信息,对于paging PDCCH based L1availability指示,当收到可用性指示信息时,可用性从参考点开始生效一段时间,其中这一段时间称为有效持续时段(validity duration),有效持续时段的时长由高层可选配置,有效持续时段开始的参考点是UE接收可用性指示信息的默认的非连续接收周期(DRX cycle)中的第一个寻呼帧(PF)所在的系统帧号(SFN)。且有效持续时段的时长以默认寻呼周期(default paging cycle)为时间单位,可用的数值有{1,2,4,8,16,32,[64],[128],[256],[512]};当高层未配置有效持续时段的时长时,UE假设有效持续时段的时长为2个default paging cycle(s)。
修改周期(modification period)用于更新除了地震海嘯告警系统(ETWS),商用移动预警系统(CMAS)和定位辅助数据相关的SI消息的其他SI消息,应用于配置了DRX cycle的UE。在一个modification period中,如果SI消息发生了更改,网络侧会在当前modification period中的paging中携带SI change指示信息;并在下一个modification period中广播更新后的系统信息。
其边界计算方式为:
SFN mod m=0;其中m为构成modification period的无线帧的数目,由系统信息配置。
在UE接收到idle/inactive TRS/CSI-RS availability indication之后,UE认为在从参考点开始的有效持续时段内idle/inactive TRS/CSI-RS一直有效,但一种场景是在所述有效持续时段内,承载idle/inactive TRS/CSI-RS occasion(s)的配置信息或者承载有效持续时段的时长可能会发生改变,当发生这种情况时,UE如何处理idle/inactive TRS/CSI-RS的有效性的行为尚不明确。
