- the terminal device in the idle state or inactive state will only try to receive the paging radio network temporary identity (paging radio network temporary identity, P at a specific PO in each DRX cycle).
- -RNTI scrambled physical downlink control channel (PDCCH).
- the PO can be regarded as a monitoring occasion for a group of PDCCHs.
- a PO may include multiple time units, for example, the time units may be time slots (slots) or orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols.
- the network device may send downlink control information (DCI) for scheduling paging messages in the PO.
- DCI downlink control information
- a paging frame (paging frame, PF) is a radio frame, which may contain one or more POs or the start of POs.
- the terminal device When monitoring the PO, the terminal device first determines the PF, and then determines the PO associated with the PF. It should be noted that the origin of a PO associated with a PF may be located within the PF, or may be located after the PF. The terminal device can determine the PO that it needs to monitor according to the paging configuration parameters and the terminal device identifier.

- FIG. 3(a) is a schematic diagram of power consumption in the process of receiving paging by a terminal device.
- the rectangles with patterns in the figure represent different power consumption states of the terminal device, and the heights of these rectangles represent the power consumption in this state. It can be seen from the figure that the power consumption per unit time in deep sleep mode is lower than the power consumption per unit time in light sleep mode. The larger the interval between SSB and PO, the higher the power consumption of the end device. To reduce power consumption due to the gap between SSB and PO, the easiest way is to send SSB more frequently. However, from the perspective of system overhead, this method is not desirable and goes against the original intention of NR systems to cancel the always-on reference signal.
- FIG. 3(b) is a schematic diagram of power consumption in the process of receiving paging by a terminal device capable of using TRS, and the meaning of the rectangle with a pattern is referred to the above description for FIG. 3(a). It can be seen from the figure that if the terminal device uses the TRS configured between PO and SSB, the terminal device can stay in the deep sleep mode for a longer time, because the power consumption per unit time in the deep sleep mode is lower than that in the light sleep mode The power consumption per unit time in the mode. Extending the time in the deep sleep mode can reduce the power consumption of the terminal device.
- the terminal device In order to enable the terminal device to skip SSB reception, the terminal device needs to know in advance whether there is a reference signal between the SSB and the PO, otherwise, in order to ensure that the PO receives the PDCCH (for example, paging DCI) and/or the physical downlink shared channel (physical downlink shared channel) channel, PDSCH) demodulation performance, the terminal device still needs to wake up at the SSB for time/frequency synchronization.
- the PDCCH for example, paging DCI

- the network device sends the configuration information of the reference signal to the terminal device, and accordingly, the terminal device receives the configuration information of the reference signal from the network device.
- the configuration information of the reference signal is used to indicate at least one resource location of the reference signal. It should be understood that the indication information that enables the terminal device to determine at least one resource location of the reference signal based on it, regardless of whether the indication information has other uses, whether it is an explicit indication or an implicit indication, can be regarded as being used to indicate the network. Whether the device sends a reference signal at the first resource location.
- the reference signal may be TRS, CSI-RS, or the like.
- the network device may configure the reference signal to be sent periodically, for example, the network device configures resource locations of at least one reference signal at equal intervals, and then selects to send the reference signal on all or part of the resource locations.
- the network device may also configure the reference signal to be bound to the PO.
- the network device is configured with at least one PO, and the terminal device determines the resource location of the at least one reference signal according to the offset information between the PO and the reference signal.

在介绍本申请的方法之前,首先对本申请涉及到的一些概念进行说明。
(一)无线资源控制(radio resource control,RRC)状态
在通信系统中,终端设备的RRC状态包括空闲态(RRC_IDLE state)、非激活态(RRC_INACTIVE state)和连接态(RRC_CONNECTED state)。
其中,当终端设备处于空闲态时,终端设备与网络设备之间的空口连接断开,且不再保存上下文信息,终端设备只能接收网络设备发送的广播信息。当终端设备处于非激活态时,终端设备与网络设备之间的空口连接断开,但是继续保存上下文信息,当终端设备由非激活态进入连接态时,能够基于保存的上下文信息快速地恢复到连接态。当终端设备处于连接态时,终端设备与网络设备之间建立空口连接,并根据空口连接与网络设备进行通信。
(二)寻呼(paging)
处于空闲态的终端设备与网络之间不存在RRC连接,处于非激活态的终端设备虽然与网络设备建立了RRC连接,但该连接处于挂起状态。当网络设备有数据要发送给处于空闲态或非激活态的终端设备时,首先需要对终端设备进行寻呼,以通知终端设备建立或恢复RRC连接,然后才能进行数据传输。寻呼可以由5G核心网(5G core network,5GC)发起,这种寻呼也称为核心网(core network,CN)寻呼。寻呼也可以由无线接入网(radio access network,RAN)发起的,这种寻呼也称为RAN寻呼。
(三)非连续接收(discontinuous reception,DRX)
处于空闲态或非激活态的终端设备支持使用DRX的方式来接收寻呼消息以降低功耗,这种DRX也称为寻呼DRX。使用DRX来接收寻呼消息时,处于空闲态或非激活态的终端设备只会在预先定义好的时间段“醒来”以接收寻呼消息,而在其它时间可以保持“休眠”状态,即,在其它时间停止接收寻呼消息,这样就降低了功耗,提升了终端设备的电池使用时间。
当使用DRX来接收寻呼消息时,DRX周期(cycle)也可被称为寻呼周期。DRX周期可以由网络设备配置。例如,网络设备可以通过下述方式来配置DRX周期:
方式一:针对CN寻呼,小区可以通过系统信息块(system information block,SIB)1中的信息元素(information element,IE)“defaultPagingCycle”来广播一个默认的(default) DRX周期;
方式二:针对CN寻呼,非接入(non-access stratum,NAS)层可以通过IE“Paging DRX”配置一个UE特定(UE-specific)的DRX周期。
方式三:针对RAN寻呼,小区可以在RRC连接挂起时,通过在“RRC Release”消息中携带IE“ran-PagingCycle”来配置一个UE特定的DRX周期。
对于处于空闲态的终端设备而言,如果通过方式二被配置了UE特定的DRX周期,可以将通过方式一被配置的默认的DRX周期、以及通过方式二被配置的UE特定的DRX周期之中的最小值作为最终使用的DRX周期。如果没有通过方式二被配置UE特定的DRX周期,则使用通过方式一被配置的默认的DRX周期。
处于非激活态的终端设备可以将通过方式一被配置的默认的DRX周期、通过方式二被配置的UE特定的DRX周期、以及通过方式三被配置的UE特定的DRX周期之中的最小值作为最终使用的DRX周期。
(四)寻呼机会(paging occasion,PO)
当使用DRX来接收寻呼消息时,处于空闲态或非激活态的终端设备只会在每个DRX周期内的某个特定PO上去尝试接收寻呼无线网络临时标识(paging radio network tempory identity,P-RNTI)加扰的物理下行控制信道(physical downlink control channel,PDCCH)。可以将PO看作一组PDCCH的监测时机(monitoring occasion)。一个PO可以包括多个时间单元,例如,时间单元可以是时隙(slots),也可以正交频分复用(orthogonal frequency division multiplexing,OFDM)符号。网络设备可以在PO中发送用于调度寻呼消息的下行控制信息(downlink control information,DCI)。另外,一个寻呼帧(paging frame,PF)是一个无线帧,可以包含一个或多个PO或PO的起点。终端设备在监测PO时,先确定PF,然后再确定PF关联的PO。需要说明的是,一个PF关联的PO的起点可以位于PF内,也可以位于PF之后。终端设备可以根据寻呼配置参数以及终端设备标识来确定自己需要监测的PO。
例如,如图2所示,网络设备每隔80毫秒配置了一个PO,对于特定终端设备来说,只需要按照自己的DRX周期监测其中部分PO。终端设备#1的DRX周期为320毫秒,监测图示中的第一个PO,之后间隔320毫秒监测下一个PO。终端设备#2的DRX周期为320毫秒,监测图示中第二个PO,之后间隔320毫秒监测下一个PO。终端设备#3的DRX周期为640毫秒,监测图示中第一个PO,之后间隔640毫秒监测下一个PO。终端设备#4的DRX周期为640毫秒,监测图示中第二个PO,之后间隔640毫秒监测下一个PO。
在本申请实施例中,当使用“间隔”来描述两个时间单元之间的距离时,可以是表示这两个时间单元的起始点之间的距离,也可以是表示这两个时间单元的中心点之间的距离,还可以是表示这两个时间单元的结束点之间的距离,或者可以表示其中一个时间单元的起始点与另一个时间单元的结束点之间的距离。这里,这两个时间单元可以是同样时长的时间单元,也可以是不同时长的时间单元。
下面将结合上文中介绍的概念,对本申请提供的技术方案进行描述。
在LTE系统中,处于空闲态和连接态的终端设备都可以利用小区参考信号(cell reference signal,CRS)进行测量、时间/频率跟踪、信道估计等。CRS是始终打开的参考信号。为了降低系统开销、小区间干扰影响、以及网络设备侧能耗,NR系统中没有定义类似CRS这样始终打开(always on)的参考信号。LTE系统中CRS支持的各个功能在 NR系统中通过不同类型的参考信号来实现。例如,信道状态信息参考信号(channel state information reference signal,CSI-RS)可用于测量下行信道质量,跟踪参考信号(tracking reference signal,TRS)可用于时间/频率跟踪和信道估计。需要注意的是,CSI-RS和TRS仅在终端设备处于连接态时可以使用。处于空闲态和非激活态的终端设备可以利用同步信号块(synchronization signal block,SSB)进行测量和时间/频率同步。因此,处于空闲态和非激活态的终端设备,需要定期唤醒以监测SSB。
为了监测PO,终端设备会在PO之前距离最近的SSB唤醒,利用该SSB进行时间/频率同步。此后,终端设备必须保持唤醒状态或浅睡眠(light sleep)模式,保持获取的时间/频率同步直到PO结束。图3(a)为终端设备接收寻呼过程中的功耗的示意图,图中具有图案的矩形表示终端设备的不同功耗状态,这些矩形的高度表示该状态下的功耗大小。从图中可以看出深睡眠(deep sleep)模式下单位时长内的功耗低于浅睡眠模式下单位时长内的功耗。SSB和PO之间的间隔越大,终端设备的功耗就越高。为了减少由于SSB和PO之间的间隔而导致的功耗,最简单的方法是更频繁地发送SSB。但是,从系统开销的角度来看,这种方法是不可取的,而且违背NR系统取消始终打开的参考信号的初衷。
除了更频繁地发送SSB之外,还可以考虑让处于空闲态和非激活态的终端设备也可以使用CSI-RS、TRS等参考信号。图3(b)为能够使用TRS的终端设备接收寻呼过程中的功耗的示意图,具有图案的矩形的含义参照上面针对图3(a)的描述。从图中可以看出如果终端设备使用在PO和SSB之间配置的TRS,则终端设备可以在深睡眠模式下停留更长的时间,由于深睡眠模式下单位时长内的功耗低于浅睡眠模式下单位时长内的功耗,拉长处于深睡眠模式的时间可以降低终端设备的功耗。
为了使得终端设备能够跳过SSB接收,终端设备需要事先知道SSB与PO之间是否存在参考信号,否则为了保证PO处接收PDCCH(例如,寻呼DCI)和/或物理下行共享信道(physical downlink shared channel,PDSCH)的解调性能,终端设备仍然需要在SSB处醒来进行时间/频率同步。
为此,本申请提供了一种参考信号的指示方法。图4是该方法的示意性流程图,如图所示,该方法包括步骤S410和步骤S420。下面对图4所示的各步骤进行说明。
在S410,网络设备向终端设备发送参考信号的配置信息,相应地,终端设备从网络设备接收参考信号的配置信息。
这里,参考信号的配置信息用于指示参考信号的至少一个资源位置。应理解的是,能够使得终端设备据此确定参考信号的至少一个资源位置的指示信息,无论该指示信息是否还有其他用途、是显示指示还是隐式指示,均可被视为用于指示网络设备是否在第一资源位置上发送参考信号。
如前所述,参考信号可以是TRS、CSI-RS等。网络设备可以将参考信号配置为周期性发送,例如,网络设备配置等间隔的至少一个参考信号的资源位置,之后选择在全部或部分的资源位置上发送参考信号。或者,网络设备也可以将参考信号配置为与PO绑定,例如,网络设备配置至少一个PO,终端设备根据PO与参考信号之间的偏移信息确定出至少一个参考信号的资源位置,该偏移信息可以是从网络设备接收的,也可以是通过其他方式获知的,例如,该配置信息可以是预设值,例如,偏移值(offset)。当通信系统支持多波束(beam)传输时,参考信号可以在多个波束方向上发送。此时,参考信号的配置信息可以包括多套配置,每一套配置对应一个波束方向。
在S420,网络设备向终端设备发送参考信号的指示信息,相应地,终端设备从网络设备接收参考信号的指示信息。
这里,参考信号的指示信息用于指示网络设备是否在第一资源位置上发送参考信号。应理解的是,能够使得终端设备据此确定网络设备是否在第一资源位置上发送参考信号的指示信息,无论该指示信息是否还有其他用途、是显示指示还是隐式指示,均可被视为用于指示网络设备是否在第一资源位置上发送参考信号。参考信号的指示信息可以只用于指示网络设备在第一资源位置上发送参考信号,也可以只用于指示网络设备不在第一资源位置上发送参考信号,或者,参考信号的指示信息的不同取值分别用于指示网络设备是否在第一资源位置上发送参考信号。
参考信号的指示信息可以被承载于在PO上接收的DCI,该DCI可以被称为寻呼DCI。对于NR系统,该DCI可用于承载短消息(short message)和/或寻呼消息的调度信息。该DCI的格式可以是冗余校验(cyclic redundancy check,CRC)通过寻呼无线网络临时标识(paging-radio network tempory identity,P-RNTI)加扰的DCI格式(format)1_0。参考信号的指示信息可以由寻呼DCI中的新增字段,或者由寻呼DCI中的原有功能字段,或者该指示字段可以是寻呼DCI中的保留(reserved)字段来进行指示。
或者,参考信号的指示信息可以被承载于用于指示终端设备是否监测(monitor)后续PO的信号,该信号可以是寻呼提前指示信号或节能信号,例如,唤醒信号(wake-up signal,WUS)、睡眠信号(go-to-sleep signal)等。为了便于描述,下面将用于接收指示信息的PO称为第一PO,或者将位于用于接收指示信息的信号之后的PO称为第一PO。第一PO可以是位于用于接收指示信息的信号之后的第一个PO,可以是用于接收指示信息的信号关联的至少一个PO,可以是用于接收指示信息的信号关联的至少一个PO(例如,该信号所指示的后续是否需要监测的PO)中的一个PO,可以是用于接收指示信息的信号关联的至少一个PO中的第一个PO,可以是用于接收指示信息的信号关联的至少一个PO中距离该信号时域位置最近的一个PO,也可以是按照某种规则确定出的PO。需要说明的是,这里描述的该信号的功能是用于指示终端设备是否监测后续PO,后续PO可以是第一PO之后的至少一个PO,该至少一个PO和第一PO可以是同一个终端设备需要监测的PO,也可以是不同终端设备需要监测的PO,终端设备确定PO位置的具体方法可以参照LTE系统或者NR系统中的现有技术。
参考信号的至少一个资源位置包括第一资源位置。第一资源位置可以是一个资源位置,也可以是多个资源位置。当第一资源位置是多个资源位置时,参考信号的指示信息可以用于针对每个资源位置分别指示网络设备是否在该资源位置上发送参考信号。
参考信号的第一资源位置可以是与第一PO之后的至少一个PO对应的参考信号的资源位置。为了便于描述,下面将与参考信号的第一资源位置对应的PO称为第二PO。第一PO与第二PO之间的间隔可以是网络设备配置的,也可以是预设值,或者可以是根据网络设备配置的参数和预设值得到的。例如,第一PO与第二PO之间的间隔可以是参考信号的周期的整数倍。参考信号的周期可以由参考信号的配置信息指示,倍数可以是预设值,也可以是网络设备指示的。或者,第一PO与第二PO之间的间隔可以是DRX周期,具体是哪个或哪些DRX周期可以是预设的。例如,第一PO与第二PO之间的间隔可以是默认的DRX周期。当存在多个默认的DRX周期时,第一PO与第二PO之间的间隔可以是默认的DRX周期中的最小值,也可以是默认的DRX周期中的最大值,或者可以存在多 个第二PO,这些第一PO与第二PO之间的间隔分别为不同的默认的DRX周期。
具体地,参考信号的第一资源位置可以是位于第二PO附近的参考信号的资源位置。当参考信号的资源位置与第二PO之间的间隔小于或等于某一阈值时,可以将该参考信号的资源位置看作第二PO附近的参考信号的资源位置。该阈值可以是网络设备配置的,也可以是预设值。或者,当参考信号为与PO在位置上绑定的参考信号时,可以将该参考信号的资源位置看作第二PO附近的参考信号的资源位置。或者说,如果终端设备利用某个参考信号进行同步的话,就能够保证第二PO处的解调性能,那么该参考信号的资源位置可以被看作第二PO附近的参考信号的资源位置。可以仅考虑位于第二PO之前,或者与第二PO属于同一个时隙、符号等的参考信号的资源位置。当存在符合前述要求的多个参考信号的资源位置时,第一资源位置可以是这些资源位置中与第二PO距离最近的参考信号的资源位置。
或者,参考信号的第一资源位置可以是位于第一PO与第二PO之间的参考信号的资源位置。可以针对第一PO与第二PO间隔的整个时段进行指示,也可以将第一PO与第二PO之间的间隔划分为多个时段,针对每个时段分别进行指示。第一PO与第二PO之间的所有网络设备配置的参考信号的资源位置可以都属于第一资源位置,也可以仅其中部分配置的参考信号的资源位置属于第一资源位置,这种情况下网络设备和终端设备需要对于哪些配置的参考信号的资源位置属于第一资源位置具有共识。
需要说明的是,第一PO和第二PO可以是同一个终端设备需要监测的PO,也可以是不同终端设备需要监测的PO。终端设备确定PO位置的具体方法可以参照LTE或者NR系统中的现有技术。
应理解的是,虽然上面以第二PO作为参照物对网络设备会在哪些参考信号的资源位置上发送参考信号进行了描述,但实际上通过其他参照物使得终端设备获知这些参考信号的资源位置的方式同样适用于本申请提供的技术方案。例如,参考信号的指示信息可以指示网络设备在至少一个时段内的参考信号的资源位置上发送参考信号,该时段的起始位置为第一PO,该时段的长度为参考信号的周期的整数倍、默认的DRX周期等。
通过参考信号的配置信息和指示信息,终端设备能够确定出网络设备在哪些资源位置上发送参考信号,从而获知后续需要监测的PO处的解调性能是否能够通过接收参考信号保证。进而,如果在无法通过接收参考信号来保证PO处的解调性能的情况下,终端设备仍需要在该PO之前距离最近的SSB唤醒的话,终端设备还可以判断出是否需要在后续需要监测的PO之前距离最近的SSB唤醒。此外,网络侧仅需要在特定时段内为了保证PO的解调性能而发送参考信号,可以降低网络设备的开销。
下面将结合具体的示例,分四种情况对参考信号的第一资源位置进行描述。
(一)参考信号的第一资源位置为一个PO附近的资源位置
如前所述,参考信号的第一资源位置可以是位于第二PO附近的参考信号的资源位置,第二PO可以是第一PO之后的一个PO。即,参考信号的指示信息用于指示网络设备是否在后续的一个PO附近的参考信号的资源位置上发送参考信号。如果该指示信息用于指示网络设备在该PO附近的参考信号的资源位置上发送参考信号,且终端设备确定需要监测该PO,就可以在该参考信号的资源位置上接收参考信号。
参考信号的指示信息可以是一个比特。当该比特的取值为“1”时,可以表示网络设备在该PO附近的参考信号的资源位置上发送参考信号;当该比特的取值为“0”时,可 以表示网络设备不在该PO附近的参考信号的资源位置上发送参考信号。
如上所述,第一PO与第二PO之间的间隔可以是网络设备配置的,也可以是预设值,或者可以是根据网络设备配置的参数和预设值得到的。第一PO与第二PO之间的间隔可以是参考信号的周期的整数倍,或者可以是DRX周期,例如,默认的DRX周期、默认的DRX周期中的最小值、默认的DRX周期中的最大值等。
下面参照图5(a)对这种方式进行示例性说明。如图5(a)所示,网络设备每隔80毫秒配置了一个PO。终端设备#1的DRX周期为320毫秒,监测图示中的第一个PO,之后间隔320毫秒监测下一个PO。终端设备#2的DRX周期为640毫秒,监测图示中第一个PO,之后间隔640毫秒监测下一个PO。第一PO(即,图示中的第一个PO)处发送的寻呼DCI中携带有取值为“1”的1比特指示信息。该指示信息“1”用于指示网络设备在第二PO(即,图示中的倒数第二个PO)对应的参考信号的资源位置上发送参考信号,该参考信号的资源位置已在图中示出。可以理解为,该指示信息针对的是640毫秒的DRX周期对应的下一个PO。
通过该指示信息,终端设备#2能够获知通过接收该参考信号,能够保证第二PO处的解调性能,不需要在第二PO之前距离最近的SSB唤醒。
除了该参考信号的资源位置之外,网络设备可能还配置了其他参考信号的资源位置,例如,与图示中倒数第三个PO对应的参考信号的资源位置等,但网络设备可以不在这些资源位置上发送参考信号。
虽然第一PO处发送的寻呼DCI中携带的指示信息仅适用于DRX周期为640毫秒的终端设备#2,不适用于DRX周期为320毫秒的终端设备#1,此外,针对终端设备#1在第一PO后监测的下一个PO(即,图示中的第五个PO),图5中也没有示出网络设备会在该PO对应的参考信号的资源位置上发送参考信号,但实际上,如果终端设备#1监测第一PO之前间隔320毫秒的PO,网络设备可以在那个PO处发送的寻呼DCI中携带取值为“1”的指示信息,这样终端设备#1就可以获知网络设备会在第一PO之后间隔320毫秒的PO对应的参考信号的资源位置上发送参考信号。
这种方式的优势在于:节约参考信号的指示信息的开销,且网络设备发送参考信号的开销较小。
(二)参考信号的第一资源位置为至少一个PO附近的资源位置
如前所述,参考信号的第一资源位置可以是位于第二PO附近的参考信号的资源位置,第二PO可以是第一PO之后的至少一个PO。即,参考信号的指示信息用于指示网络设备是否在后续的至少一个PO附近的参考信号的资源位置上发送参考信号。当仅针对一个PO进行指示时,与(一)中相同,如果该指示信息用于指示网络设备在该PO附近的参考信号的资源位置上发送参考信号,且终端设备确定需要监测该PO,就可以在该参考信号的资源位置上接收参考信号。当针对多于一个PO进行指示时,如果该指示信息用于指示网络设备在这些PO中的某个PO附近的参考信号的资源位置上发送参考信号,且终端设备需要监测该PO,就可以在该参考信号的资源位置上接收参考信号。
参考信号的指示信息可以是一个比特组,该比特组包含的比特数与该指示信息所针对的PO的数量相同。比特组中的每个比特对应于一个PO,即,至少一个比特与至少一个PO一一对应。当某个比特的取值为“1”时,可以表示网络设备在该比特对应的PO附近的参考信号的资源位置上发送参考信号;当某个比特的取值为“0”时,可以表示网络设 备不在该比特对应的PO附近的参考信号的资源位置上发送参考信号。
如上所述,第一PO与第二PO之间的间隔可以是网络设备配置的,也可以是预设值,或者可以是根据网络设备配置的参数和预设值得到的。第一PO与第二PO之间的间隔可以是参考信号的周期的整数倍,或者可以是DRX周期,例如,默认的DRX周期、默认的DRX周期中的最小值、默认的DRX周期中的最大值等。当第一PO与第二PO之间的间隔为DRX周期时,比特组中的每个比特对应于一个PO也可以被理解为:比特组中的每个比特对应于一种DRX周期。低比特位可以对应于较小的DRX周期,高比特位可以对应于较大的DRX周期,或者反之。
该比特组包含的比特数可以是预设值,例如,预设值可以是1到6的正整数。
或者,该比特组包含的比特数可以是默认的DRX周期的配置参数的条目的数量。例如,当默认的DRX周期的配置参数的所有条目为320毫秒、640毫秒、1280毫秒和2560毫秒时,这些条目的数量为4,因此,比特组包含的比特数为4。
又或者,该比特组包含的比特数可以是默认的DRX周期的配置参数的条目中小于或等于默认的DRX周期的条目的数量。例如,当默认的DRX周期的配置参数的所有条目为320毫秒、640毫秒、1280毫秒和2560毫秒时,如果网络设备配置的默认的DRX周期为1280毫秒,则这些条目中小于或等于默认的DRX周期的条目为320毫秒、640毫秒、1280毫秒,其数量为3,因此,比特组包含的比特数为3。如前所述,终端设备最终使用的DRX周期为终端设备的默认的DRX周期和特定的DRX周期之中的最小值,因此终端设备最终使用的DRX周期一定小于或等于默认的DRX周期。
下面参照图5(b)对这种方式进行示例性说明。如图5(b)所示,网络设备每隔80毫秒配置了一个PO。终端设备#1的DRX周期为320毫秒,监测图示中的第一个PO,之后间隔320毫秒监测下一个PO。终端设备#2的DRX周期为640毫秒,监测图示中第一个PO,之后间隔640毫秒监测下一个PO。第一PO(即,图示中的第一个PO)处发送的寻呼DCI中携带有取值为“01”的2比特指示信息。该指示信息的第一个比特“0”用于指示网络设备不在第二PO#1(即,图示中的第五个PO)对应的参考信号的资源位置上发送参考信号。该指示信息的第二个比特“1”用于指示网络设备在第二PO#2对应的参考信号的资源位置上发送参考信号,该参考信号的资源位置已在图中示出。可以理解为,该指示信息的第一个比特针对的是320毫秒的DRX周期对应的下一个PO,第二个比特针对的是640毫秒的DRX周期对应的下一个PO。
通过该指示信息,终端设备#1能够获知第二PO#1处的解调性能无法通过接收参考信号保证,需要在第二PO#1之前距离最近的SSB唤醒。此外,通过该指示信息,终端设备#2能够获知通过接收该参考信号,能够保证第二PO#2处的解调性能,不需要在第二PO#2之前距离最近的SSB唤醒。
除了该参考信号的资源位置之外,网络设备可能还配置了其他参考信号的资源位置,例如,与倒数第三个PO对应的参考信号的资源位置等,但网络设备可以不在这些资源位置上发送参考信号。
这种方式的优势在于:可以按需求选择针对不同数量的PO附近的参考信号的资源位置进行指示,且在针对多个PO附近的参考信号的资源位置进行指示时,还可以分别指示不同的PO附近的参考信号的资源位置上有无参考信号发送,增强了指示的灵活性;此外,网络设备发送参考信号的开销相对较小。
(三)参考信号的第一资源位置为一个时段内的资源位置
如前所述,参考信号的第一资源位置可以是位于第一PO与第二PO之间的参考信号的资源位置,可以针对第一PO与第二PO间隔的整个时段进行指示。即,参考信号的指示信息用于指示网络设备是否在后续的一个时段内的参考信号的资源位置上发送参考信号。如果该指示信息用于指示网络设备在该时段内的参考信号的资源位置上发送参考信号,且终端设备确定需要监测这些参考信号中某个参考信号附近的PO,就可以在该参考信号的资源位置上接收参考信号。
参考信号的指示信息可以是一个比特。当该比特的取值为“1”时,可以表示网络设备在该时段内的参考信号的资源位置上发送参考信号;当该比特的取值为“0”时,可以表示网络设备不在时段内的参考信号的资源位置上发送参考信号。
如上所述,第一PO与第二PO之间的间隔可以是网络设备配置的,也可以是预设值,或者可以是根据网络设备配置的参数和预设值得到的。第一PO与第二PO之间的间隔可以是参考信号的周期的整数倍,或者可以是DRX周期,例如,默认的DRX周期、默认的DRX周期中的最小值、默认的DRX周期中的最大值等。
下面参照图5(c)对这种方式进行示例性说明。如图5(c)所示,网络设备每隔80毫秒配置了一个PO,且每隔80毫秒配置了一个参考信号的资源位置。终端设备#1的DRX周期为320毫秒,监测图示中的第一个PO,之后间隔320毫秒监测下一个PO。终端设备#2的DRX周期为640毫秒,监测图示中第一个PO,之后间隔640毫秒监测下一个PO。第一PO(即,图示中的第一个PO)处发送的寻呼DCI中携带有取值为“1”的1比特指示信息。该指示信息“1”用于指示网络设备在第一PO与第二PO(即,图示中的倒数第二个PO)之间的参考信号的资源位置上发送参考信号,这些参考信号的资源位置已在图中示出。可以理解为,该指示信息针对的是以第一PO为起点的时长为640毫秒的时段。
通过该指示信息,终端设备#1能够获知通过接收这些参考信号中的某个参考信号(例如,图示中第四个参考信号),能够保证第一个PO之后间隔320毫秒的PO(即,图示中的第五个PO)处的解调性能,不需要在该PO之前距离最近的SSB唤醒。此外,通过该指示信息,终端设备#2能够获知通过接收这些参考信号中的某个参考信号(例如,图示中最后一个参考信号),能够保证第二PO处的解调性能,不需要在第二PO之前距离最近的SSB唤醒。
除了这些参考信号的资源位置之外,网络设备可能还配置了其他参考信号的资源位置,例如,图示中最后一个参考信号之后间隔80毫秒的参考信号的资源位置等,但网络设备可以不在这些资源位置上发送参考信号。
这种方式的优势在于,节约参考信号的指示信息的开销,此外,在某些情况下,终端设备可能会有较大概率能够通过接收参考信号来保证PO处的解调性能。
(四)参考信号的第一资源位置为至少一个时段内的资源位置
如前所述,参考信号的第一资源位置可以是位于第一PO与第二PO之间的参考信号的资源位置,可以视情况针对第一PO与第二PO间隔的整个时段进行指示,或者将第一PO与第二PO之间的间隔划分为多个时段,针对每个时段分别进行指示。当存在多个时段时,这些时段可以是等长的,也可以是非等长的。应理解的是,虽然这里使用“划分”进行描述,但仅用其描述第一PO与第二PO之间的间隔与上述多个时段之间的关系,实际上可以没有划分的处理,网络设备和终端设备可以直接确定多个时段。即,参考信号的 指示信息用于指示网络设备是否在后续的至少一个时段内的参考信号的资源位置上发送参考信号。如果该指示信息用于指示网络设备在这些时段中的某个时段内的参考信号的资源位置上发送参考信号,且终端设备确定需要监测这些参考信号中某个参考信号附近的PO,就可以在该参考信号的资源位置上接收参考信号。
参考信号的指示信息可以是一个比特组,该比特组包含的比特数与该指示信息所针对的时段的数量相同。比特组中的每个比特对应于一个时段,即,至少一个比特与至少一个时段一一对应。当某个比特的取值为“1”时,可以表示网络设备在该比特对应的时段内的参考信号的资源位置上发送参考信号;当某个比特的取值为“0”时,可以表示网络设备不在该比特对应的时段内的参考信号的资源位置上发送参考信号。
如上所述,第一PO与第二PO之间的间隔可以是网络设备配置的,也可以是预设值,或者可以是根据网络设备配置的参数和预设值得到的。第一PO与第二PO之间的间隔可以是参考信号的周期的整数倍,或者可以是DRX周期,例如,默认的DRX周期、默认的DRX周期中的最小值、默认的DRX周期中的最大值等。可以针对第一PO与第二PO之间的间隔进行设置,再针对该间隔内时段的数量及划分进行设置。也可以直接针对至少一个时段进行设置。还可以默认多个时段是等长的,针对第一PO与第二PO之间的间隔进行设置,再针对每个时段的时长进行设置。这里所说的“设置”可以理解为如上所述的通过网络设备配置和/或预设值进行设置。针对至少一个时段,每个时段可以是参考信号的周期的整数倍,例如,每个时段为参考信号的一个周期。或者,每个时段可以是DRX周期,例如,默认的DRX周期中的最小值、特定的DRX周期中的最小值。
下面参照图5(d)对这种方式进行示例性说明。如图5(d)所示,网络设备每隔80毫秒配置了一个PO,且每隔80毫秒配置了一个参考信号的资源位置。终端设备#1的DRX周期为320毫秒,监测图示中的第一个PO,之后间隔320毫秒监测下一个PO。终端设备#2的DRX周期为640毫秒,监测图示中第一个PO,之后间隔640毫秒监测下一个PO。第一PO(即,图示中的第一个PO)处发送的寻呼DCI中携带有取值为“0110”的4比特指示信息。将第一PO与第二PO(即,图示中的倒数第二个PO)之间的时段划分为时长为160毫秒的四个时段。第一个比特“0”用于指示网络设备不在第一个160毫秒的时段内的参考信号的资源位置上发送参考信号。第二个比特“1”用于指示网络设备在第二个160毫秒的时段内的参考信号的资源位置上发送参考信号,这些参考信号的资源位置已在图中示出。第三个比特“1”用于指示网络设备在第三个160毫秒的时段内的参考信号的资源位置上发送参考信号,这些参考信号的资源位置已在图中示出。第四个比特“0”用于指示网络设备不在第四个160毫秒的时段内的参考信号的资源位置上发送参考信号。可以理解为,该指示信息的第一个比特针对的是以第一PO为起点的时长为160毫秒的时段,该指示信息的第二个比特针对的是第一PO之后间隔160毫秒的时长为160毫秒的时段,该指示信息的第三个比特针对的是第一PO之后间隔320毫秒的时长为160毫秒的时段,该指示信息的第四个比特针对的是第一PO之后间隔480毫秒的时长为160毫秒的时段。
通过该指示信息,终端设备#1能够获知通过接收这些参考信号中的某个参考信号(例如,图示中第四个参考信号),能够保证第一个PO之后间隔320毫秒的PO(即,图示中的第五个PO)处的解调性能,不需要在该PO之前距离最近的SSB唤醒。此外,通过该指示信息,终端设备#2能够获知第二PO处的解调性能无法通过接收参考信号保证,需 要在第二PO之前距离最近的SSB唤醒。
除了这些参考信号的资源位置之外,网络设备可能还配置了其他参考信号的资源位置,例如,图示中最后一个参考信号之后间隔80毫秒的参考信号的资源位置等,但网络设备可以不在这些资源位置上发送参考信号。
这种方式的优势在于:可以按需求选择针对不同数量及粒度的时段的参考信号的资源位置进行指示,且在针对多个时段内的参考信号的资源位置进行指示时,还可以分别指示不同的时段内的参考信号的资源位置上有无参考信号发送,增强了指示的灵活性;此外,在某些情况下,终端设备可能会有较大概率能够通过接收参考信号来保证PO处的解调性能,而且网络设备发送参考信号的开销相对较小。
