- CA Carrier aggregation
- LTE long term evolution
- the maximum bandwidth of a carrier is 20MHz.
- LTE-A LTE has been further improved, called LTE-A.
- LTE-A In order to meet the requirements of LTE-A downlink peak speed of 1Gbps and uplink peak speed of 500Mbps, it is necessary to provide a maximum transmission bandwidth of 100MHz.
- LTE-A has proposed a solution for carrier aggregation.
- Carrier aggregation is the aggregation of two or more component carriers (CC) to support a larger transmission bandwidth.
- CC component carriers
- a terminal can be configured with multiple CCs, one of which is called a primary cell (PCell), which is a cell where the terminal performs initial access, or a cell that performs radio resource control (RRC) connection reestablishment, Or the primary cell specified during handover.
- the PCell is responsible for RRC communication with the terminal, and the physical uplink control channel (physical uplink control channel, PUCCH) is only sent on the PCell.
- the remaining CCs are called secondary cells (SCells) and are added during RRC reconfiguration to provide additional radio resources.
- the terminal can support large bandwidth through an in-band continuous CA (intra-band continuous CA).
- in-band continuous CA intra-band continuous CA
- the terminal can treat the bandwidth of the base station as an aggregation of four 100 MHz bandwidths, and communicate with the base station in the manner of CA.
- BWP bandwidth between the network device and the UE for transmission. Since the 5G system bandwidth (referred to as the bandwidth of one carrier, corresponding to the bandwidth of each CC in a CA or dual connectivity (DC) scenario) can be 200MHz or 400MHz, some terminals do not support such a large bandwidth, so network equipment can The terminal is configured with a BWP (part of the system bandwidth), for example, 20MHz, and the terminal can communicate with the network device at this 20MHz.
- the 5G system bandwidth referred to as the bandwidth of one carrier, corresponding to the bandwidth of each CC in a CA or dual connectivity (DC) scenario
- BWP part of the system bandwidth
- the BWP can be divided into downlink BWP (downlink BWP, DL BWP) and uplink BWP (uplink BWP, UL BWP).
- the network device can configure multiple DL BWP and/or multiple UL BWP for the terminal, and activate at least one DL BWP and at least A UL BWP, the UE receives the downlink signals sent by the network device on the activated DL BWP, including but not limited to: downlink control signaling, downlink data, etc.; the terminal sends uplink signals on the activated UL BWP, including but not limited to: uplink Control signaling, uplink data, uplink scheduling request (SR), uplink sounding reference signal (SRS), channel state information (channel state information, CSI), channel quality indicator (channel quality indicator (CQI) Feedback, etc.
- uplink Control signaling uplink data
- SR uplink scheduling request
- SRS uplink sounding reference signal
- CQI channel quality indicator
- NR supports multiple numerology, each numerology is determined by sub-carrier spacing (SCS) and cyclic prefix (CP).
- SCS sub-carrier spacing
- CP cyclic prefix
- Different numerology can be time division multiplexed or frequency division multiplexed, that is, different numerology can be used in different time or frequency domains.
- the numerology of different CCs or BWPs can be different. Different numerology will result in different slot lengths. As shown in Figure 1, for example, when the subcarrier spacing of CC1 is 30 kHz and the subcarrier spacing of CC2 is 15 kHz, the length of one slot on CC2 is equal to the length of two slots on CC1.
- the network device may indicate whether the terminal monitors the physical downlink control channel (physical downlink control channel, PDCCH) through a power saving signal.
- PDCCH physical downlink control channel
- the terminal monitors the PDCCH during a period when the network device may schedule the terminal, that is, in a wake-up state; and does not monitor the PDCCH during the period when the network device does not schedule the terminal, that is, in the sleep state.
- the wake-up signal is used to notify the terminal when the terminal enters the wake-up state when the terminal is in the sleep state (ie, does not monitor the PDCCH, and/or does not receive the downlink reference signal, and/or does not perform measurement).
- monitoring PDCCH and/or receive downlink reference signals, and/or perform measurements.
- the second is the sleep signal, which is used to notify the terminal when the terminal enters the sleep state without monitoring the PDCCH when the terminal is in the awake state (ie, monitoring the PDCCH according to configuration parameters, and/or receiving downlink reference signals, and/or performing measurements), and /Or no downlink reference signal is received, and/or no measurement is performed.
- the third is a general power-saving signal, which contains indication information, which further indicates whether the terminal needs to be in awake state or sleep state in the next period of time; after receiving the signal, the terminal determines the subsequent time according to the indication information Whether it is awake or sleeping.
- the network device may notify the terminal to enter a sleep state to reduce power consumption of the terminal. For example, if terminal A does not perform uplink or downlink data transmission with a network device for a period of time, the network device may infer that terminal A is likely to have no data transmission requirements for a period of time in the future, so it sends a power saving signal to terminal A , Notify terminal A to enter the sleep state within a period of time in the future to save power consumption.
- a power saving signal is sent to terminal B to inform terminal B that it is not necessary to monitor in a future period of time PDCCH to save the power consumption of terminal B.
- the power saving signal can be sent to the terminal through DCI.
- the reliability is high and the probability of missed/false detection is low; however, the existing DCI format (DCI format) needs to be modified, or a new DCI format needs to be introduced.
- the power saving signal can also be sent to the terminal through a sequence or reference signal (RS), without designing the DCI format, without increasing the complexity of the blind DCI detection of the terminal; however, the reliability is low, and the detection/misdetection is low The probability is large, and air interface resources may be wasted.
- RS sequence or reference signal
- the power saving signal may be sent separately for each CC, indicating the status of the terminal on each CC.
- the power saving signal is more likely to be sent on one CC.
- the power saving signal sent on one CC may indicate the status of the terminal on multiple CCs.
- the power saving signal may also be sent separately on each BWP, but in order to save signaling overhead, it is more likely to be sent on only one BWP, indicating the status of the terminal on multiple BWPs.
- the terminal determines that the terminal is in a sleep state on CC1 (or BWP1) and awake on CC2 (or BWP2) at a certain time according to the power saving signal, the related circuit of the terminal cannot be completely shut down.
- the effect is not significant.
- the ideal state is that the terminal is not scheduled on all CCs (or BWP) when there is no business demand; when the service needs, the terminal is scheduled on each CC (or BWP) at the same time, which helps to improve data Transmission efficiency, reduce transmission delay.
- the network device indicates the status of the terminal on multiple CCs (or multiple BWPs) on one CC (or one BWP), how does the terminal save the signal according to the power consumption sent on one CC (or one BWP), To determine the status on multiple CCs (or multiple BWPs), there is no clear solution in the current standard.
- FIG. 2 exemplarily provides an application scenario of the communication method provided by the embodiment of the present application.
- the signaling of the power saving signal is not limited, and the network device can be sent to the terminal through DCI, or can be sent to the terminal through a sequence or reference signal, and of course, can also be sent to the terminal through other signaling .
- the network device in the embodiment of the present application may be a base station, or other devices used to convert received air frames and internet protocol (IP) packets to each other as the wireless terminal and the rest of the access network Between the routers, the rest of the access network can include IP networks. Network equipment can also be used to coordinate attribute management of the air interface. Among them, in communication systems that use different wireless access technologies, the names of devices with base station functions may be different.
- the base station in the LTE system is called an evolutionary base station (evolutionary node B, eNB), NR system Base station (gNB), etc.

- the power saving signal may be carried in the DCI signaling and sent to the terminal, and the DCI carrying the power saving signal may be a DCI dedicated to the power saving signal, or, in addition to the DCI carrying the power saving signal , Also carries scheduling information for scheduling uplink data or downlink data.
- the power saving signal and the scheduling information multiplex a DCI, the terminal and the network device first complete the transmission of uplink data or downlink data according to the scheduling information, and then the terminal enters the sleep state.
- the terminal first receives the downlink data sent by the network device (or sends the uplink data to the network device) according to the DCI ), and then enter the sleep state. At this time, the terminal may use the first symbol or the first time slot after the last symbol of downlink data (or uplink data) as the first period (and/or second period)
- the start time is shown in Figure 16.
- a hybrid automatic repeat request (HARQ) mechanism may be introduced.
- the terminal After receiving the downlink data, the terminal returns an acknowledgment frame (ACK/NACK) to the network device, indicating whether the terminal successfully received the downlink data. If the reception fails, the network device can resend the scheduling information and resend the downlink data; the terminal is sending After the network device sends the uplink data, if the network device fails to receive, it can send scheduling information to the terminal again to enable the terminal to re-send the uplink data, as shown in FIG. 17.

- the terminal receives DCI in time slot 0, and the DCI includes scheduling information of downlink data and a power-saving signal, instructing the terminal to receive downlink data in time slot 0, after 5 hours Sleep can be entered in the gap.
- the terminal determines that time slot 0 is the start time of the first time period, and the duration of the first time period is 5 time slots (ie, time slot 0 to time slot 4); the terminal receives downlink data in time slot 0 and ACK/NACK is fed back on 1, assuming that the preset duration is 2 time slots. If the terminal does not receive the scheduling information sent by the network device in the 2 time slots after the feedback ACK/NACK (ie, time slot 2 and time slot 3), Then from the time slot 4 to enter the sleep state.
- the terminal uses the first symbol or the first time slot after the last symbol of the received downlink data as the starting time of the first period, the terminal needs to feedback ACK/NACK and wait for a preset period of time before it can enter Sleep state.

- the terminal uses the first symbol or the first time slot after sending ACK/NACK as the starting time of the first time period, the terminal also needs to wait for a preset time period before the network device does not resend scheduling information before it can actually go to sleep status. For example, as shown in FIG. 18, the terminal receives DCI in time slot 0, receives downlink data in time slot 0, and feeds back ACK/NACK in time slot 1.
- the terminal may use time slot 2 as the beginning of the first time period Time, assuming that the preset duration is 2 time slots, if the terminal does not receive the scheduling information sent by the network device in the 2 time slots after the ACK/NACK feedback (ie, time slot 2 and time slot 3), then the time slot 4 Start to enter the sleep state, that is, the terminal is in the sleep state on time slot 4 to time slot 6.
- the first period is the period when the terminal actually enters the sleep state.
- the terminal receives DCI in time slot 0, and the DCI includes scheduling information of downlink data and a power-saving signal, instructing the terminal to receive downlink data in time slot 0, after 5 hours Sleep can be entered in the gap.

Description
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
终端的待机时间是影响用户体验的一个重要部分。由于5G新空口(new radio,NR)***需要支持比长期演进(long term evolution,LTE)***更大的带宽,更高的传输速率,更广的覆盖范围,因此NR终端的功耗比LTE终端的功耗更大。为了保证良好的用户体验,第三代移动通信标准化组织(3rd generation partnership project,3GPP)在Rel-16中针对终端功耗节省课题进行了专门的立项,研究减少终端功耗的优化方案。
为了达到节能的目的,可以从两方面进行优化:一是在有业务负载(即有数据需要传输)时,提升数据传输效率;二是在没有业务负载时,减少能量消耗。针对第二点,在国际电信联盟无线电通信组(international telecommunication union–radiocommunicationssector,ITU-R)的报告中提到,可以通过增大终端处于睡眠状态的比例来达到减少能量消耗的目的。
发明内容
本申请实施例提供一种通信方法,用以实现终端根据一个功耗节省信号确定在不同频域资源上的睡眠时间或唤醒时间。
第一方面,本申请实施例提供了一种通信方法,包括:
网络设备向终端发送功耗节省信号,该功耗节省信号指示N个时间单元,N为大于0的数;终端在接收到该功耗节省信号后,确定该终端在第一频域资源上与上述N个时间单元对应的第一时段内的状态,以及在第二频域资源上与上述N个时间单元对应的第二时段内的状态。其中,状态指睡眠状态或唤醒状态,睡眠状态表示终端不监测第一信号,唤醒状态表示终端根据配置参数监测第一信号。
在上述实施例中,终端在接收到功耗节省信号后,确定该信号指示的N个时间单元在不同频域资源上对应的时段,而不是简单的确定在不同的频域资源上在不同频域资源上睡眠时间或唤醒时间均为N个时间单元。由于令终端在不同频域资源上的状态趋近同步,有助于功耗的节省。
在一种可能的实现方式中,可以令第一频域资源上第一时段的绝对时长与上述N个时间单元的绝对时长相等或近似相等,令第二频域资源上的第二时段的绝对时长与上述N个时间单元绝对时长相等或近似相等。
在一种可能的实现方式中,上述功耗节省信号所指示的时间单元为时隙,则第一时段的时长为第一频域资源的N个时隙,终端根据第一频域资源配置的子载波间隔、第二频域资源配置的子载波间隔以及N确定第二时段的时长。在该实施例中,网络设备以第一频域资源作为参考,指示的N个时隙即为第一频域资源上的N个时隙,终端进一步确定第一频域资源上的N个时隙对应的第二时段的时长。
在一种可能的实现方式,可以确定第一频域资源上的N个时隙的绝对时长,确定在第二频域资源上与上述绝对时长相等或近似相等的时隙数量。
在一种可能的实现方式中,第一频域资源配置的子载波间隔为15*2M1kHz,第二频域资源配置的子载波间隔为15*2M2kHz,其中,M1、M2为大于等于0的整数;则终端确定第二时段的时长为第二频域资源上的N*2M2-M1个时隙,或者
个时隙,或者
个时隙。进一步地,令M2 ≥M1,可以使得第二时段的时长为整数个时隙,避免非整数个时隙的情况,方便终端操作。
在一种可能的实现方式中,终端根据第一频域资源的子载波间隔、第二频域资源的子载波间隔以及N,查表确定第二时段的时长。
在一种可能的实现方式中,上述功耗节省信号所指示的时间单元为时隙;该方法还包括:网络设备在发送上述功耗节省信号之前,还向终端发送第一配置信息,该第一配置信息包括该功耗节省信号的参考子载波间隔。终端则根据参考子载波间隔、第一频域资源的子载波间隔、以及N个时间单元确定第一时段的时长,根据参考子载波间隔、第二频域资源的子载波间隔以及N个时间单元确定第二时段的时长。
在一种可能的实现方式中,可以确定在参考子载波间隔情况下N个时隙的绝对时长,确定在第一频域资源上与上述绝对时长相等或近似相等的时隙数量,确定在第二频域资源上与上述绝对时长相等或进行相等的时隙数量。
在一种可能的实现方式中,上述参考子载波间隔为15*2M0kHz,所述第一频域资源配置的子载波间隔15*2M1kHz,所述第二频域资源配置的子载波间隔15*2M2kHz;终端确定第一时段的时长为第一频域资源上的N*2M1-M0个时隙,或者
个时隙,或者
个时隙;第二时段的时长为第二频域资源上的N*2M2-M0个时隙,或者
个时隙,或者
个时隙。进一步地,令M1≥M0,M2≥M0可以使得第一时段的时长、第二时段的时长为整数个时隙,避免非整数个时隙的情况,方便终端操作。
在一种可能的实现方式中,若第一时段的时长为非整数个时隙和/或第二时段的时长为非整数个时隙,则终端向网络设备报错。终端可能不期望第一时段和第二时段的时长为非整数个时隙,因此,若终端确定出第一时段和/或第二时段的时长为非整数个时隙,则不执行相应的睡眠或唤醒操作,而是向网络设备报错。对应的,网络设备也可以预先估计第一时段和第二时段的时长,尽量使得N个时间单元对应的第一时段和第二时段为整数个时隙。

在一种可能的实现方式中,上述第一时段和第二时段由连续的时隙组成。
在一种可能的实现方式中,上述功耗节省信号所指示的时间单元为监测时机,由于终端根据配置参数监测第一信号时,可能并不会持续监测,例如,在每个时隙中的第一个符号或前几个符号上监测第一信号,或者,在每两个时隙的前几个符号上监测第一信号,在一个监测周期中监测第一信号的时刻被称为一个监测时机。
第一时段的时长为第一频域资源上的N个监测周期,或者N*L1个时隙,其中,L表示终端在第一频域资源上的监测周期为L1个时隙,L1为大于等于1的整数。网络设备以第一频域资源作为参考,指示的N个监测时机即为第一频域资源上的N个监测时机。在一个监测周期中,终端在监测时机上监测第一信号,在其他时段上不监测第一信号,因此,若网络设备指示终端在下一个监测时机上不监测,则终端在下一个监测周期中均不会监测第一信号,故网络设备指示N个监测时机不监测,则终端在N个监测周期中均不监测。
在一种可能的实现方式,可以确定第一频域资源上的N个监测周期的绝对时长,确定在第二频域资 源上与上述绝对时长相等或近似相等的监测周期的数量。
在一种可能的实现方式中,第一频域资源配置的子载波间隔为15*2M1kHz,第二频域资源配置的子载波间隔为15*2M2kHz,终端在第二频域资源上的监测周期为L2个时隙,其中,M1、M2为大于等于0的整数,L2为大于等于1的整数;则第二时段的时长为第二频域资源上的

为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述。
首先对本申请涉及的概念进行解释说明。
-载波聚合(carrier aggregation,CA)
在长期演进(long term evolution,LTE)标准制定的初始阶段,规定了一个载波的带宽最大为20MHz。在之后的标准化过程中,对LTE进行了进一步的改进,被称为LTE-A。为了满足LTE-A下行峰速1Gbps、上行峰速500Mbps的要求,需要提供最大100MHz的传输带宽。但由于大带宽连续频谱的稀缺,LTE-A提出了载波聚合的解决方案。载波聚合是将2个或更多的组分载波(component carrier, CC)聚合在一起以支持更大的传输带宽。通常可以将1个CC等同于1个小区,每个CC的最大带宽为20MHz。
一个终端可以配置多个CC,其中一个CC被称为主小区(primary cell,PCell),是终端进行初始接入的小区,或者是进行无线资源控制(radio resource control,RRC)连接重建的小区,或是在切换(handover)过程中指定的主小区。PCell负责与终端进行RRC的通信,物理上行控制信道(physical uplink control channel,PUCCH)仅在PCell上发送。其余CC被称为辅小区(secondary cell,SCell),是在RRC重配置时添加的,用于提供额外的无线资源。
在新空口(new radio,NR)中,仍采用CA技术,其中上行、下行分别最多支持16个CC。同时,在基站带宽较大,终端能力不足无法通过单载波支持大带宽时,终端可以通过带内连续CA(intra band contiguous CA)的方式支持大带宽。比如,基站带宽为400MHz,而终端支持的最大连续带宽为100MHz时,终端可以将基站的带宽当作4个100MHz带宽的聚合,采用CA的方式与基站通信。
-带宽部分(BWP)
NR中引入了BWP的概念,即,支持网络设备和UE之间占用一部分带宽进行传输。由于5G的***带宽(指一个载波的带宽,对应CA或者双连接(dual connectivity,DC)场景中每个CC的带宽)可以为200MHz或者400MHz,有些终端不支持这样的大带宽,因此网络设备可以给终端配置BWP(***带宽的一部分),例如20MHz,终端可以在这20MHz上与网络设备进行通信。
BWP可以分为下行BWP(downlink BWP,DL BWP)和上行BWP(uplink BWP,UL BWP),网络设备可以为终端配置多个DL BWP和/或多个UL BWP,并且激活至少一个DL BWP和至少一个UL BWP,UE在激活的DL BWP上接收网络设备发送的下行信号,包括但不限于:下行控制信令,下行数据等;终端在激活的UL BWP上发送上行信号,包括但不限于:上行控制信令,上行数据,上行调度请求(scheduling request,SR),上行探测参考信号(sounding reference signal,SRS),信道状态信息(channel state information,CSI),信道质量指示(channel quality indicator,CQI)反馈等等。
-参数集(numerology)
在NR的标准化中,引入了numerology的概念。NR中支持多种numerology,每一种numerology由子载波间隔(sub-carrier spacing,SCS)以及循环前缀(cyclic shift,CP)决定。不同的numerology可以时分复用或者频分复用,即,在不同的时间或频域上可以使用不同的numerology。
不同CC或BWP的numerology可以是不同的。不同numerology会导致时隙长度的不同。如下图1所示,比如CC1的子载波间隔为30kHz,CC2的子载波间隔为15kHz的时候,CC2上的一个时隙的长度等于CC1上两个时隙的长度。
-功耗节省信号(power saving signal)
为了节省终端的功耗,网络设备可以通过功耗节省信号(power saving signal)指示终端是否监测物理下行控制信道(physical downlink control channel,PDCCH)。终端根据该功耗节省信号,在网络设备可能会调度该终端的时段内监测PDCCH,即处于唤醒状态;而在网络设备不会调度该终端的时段内不监测PDCCH,即处于睡眠状态。功耗节省信号有以下三种实现方式:
一是唤醒信号,作用是在终端处于睡眠状态(即不监测PDCCH,和/或不接收下行参考信号,和/或不进行测量)时,通知终端在何时进入唤醒状态,根据配置参数、监测PDCCH,和/或接收下行参考信号,和/或进行测量。
二是睡眠信号,作用是在终端处于唤醒状态(即根据配置参数监测PDCCH,和/或接收下行参考信号,和/或进行测量)时,通知终端在何时进入睡眠状态,不监测PDCCH,和/或不接收下行参考信号, 和/或不进行测量。
三是通用的功耗节省信号,在信号中包含指示信息,进一步指示终端在接下来的一段时间内是需要处于唤醒状态还是睡眠状态;终端接收到该信号后,根据指示信息确定在随后的时间内处于唤醒状态还是睡眠状态。
终端处于睡眠状态时,可以关闭相关电路,从而降低自身功耗。
若网络设备在确定某个时段内不会向终端发送PDCCH时,可以通知终端进入睡眠状态,以降低终端的功耗。例如,若终端A在一段时间内没有与网络设备进行上行或下行数据传输,则网络设备可以推断终端A在未来一段时间内较大可能没有数据传输的需求,故而向终端A发送功耗节省信号,通知终端A在未来一段时间内进入睡眠状态,以节省功耗。又例如,若网络设备当前十分繁忙,待接收或发送的数据较多,在未来一段时间内无暇调度终端B,故而向终端B发送功耗节省信号,通知终端B在未来一段时间内不必再监测PDCCH,以节省终端B的功耗。
功耗节省信号可以通过DCI发送给终端,可靠性较高,漏检/误检概率较小;但需要修改现有的DCI格式(DCI format),或者引入新的DCI format。
功耗节省信号也可以通过序列(sequence)或参考信号(reference signal,RS)发送给终端,无需设计DCI format,不增加终端盲检DCI的复杂度;但可靠性较低,漏检/误检概率大,且有可能浪费空口资源。
在CA的场景下,功耗节省信号可以在每个CC分别发送,分别指示每个CC上终端的状态。但是,为了节省信令开销,功耗节省信号较大可能在一个CC上发送,此时在一个CC上发送的功耗节省信号可以指示终端在多个CC上的状态。
同样的,在BWP场景下,功耗节省信号也可以在每个BWP上分别发送,但为了节省信令开销,较大可能仅在一个BWP上发送,指示终端在多个BWP上的状态。
若终端根据功耗节省信号确定在某一时刻,终端在CC1(或BWP1)上处于睡眠状态,在CC2(或BWP2)上处于唤醒状态,则终端的相关电路并不能完全关闭,节省功耗的作用不显著。理想的状态是,终端在没有业务需求时,在所有的CC(或BWP)上均不被调度;在有业务需要时,终端在各个CC(或BWP)上同时被调度,有助于提高数据传输效率、降低传输时延。
然而,当网络设备在一个CC(或一个BWP)上指示终端在多个CC(或多个BWP)上的状态时,终端如何根据在一个CC(或一个BWP)上发送的功耗节省信号,确定在多个CC(或多个BWP)上的状态,目前标准中还没有明确的解决方案。
为了解决上述问题,本申请实施例提供了一种通信方法及装置,用于实现终端根据一个频域资源上接收到的功耗节省信号确定在不同频域资源上的状态。图2示例性的提供了一种本申请实施例提供的通信方法的应用场景。
在本申请实施例中,并不对功耗节省信号的信令进行限定,网络设备可以通过DCI发送给终端,也可以通过序列或参考信号发送给终端,当然,还可以通过其它信令发送给终端。
结合图2,本申请实施例中的网络设备可以为基站,或其他用于将收到的空中帧与网际协议(internet protocol,IP)分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括IP网络。网络设备还可用于协调对空中接口的属性管理。其中,在采用不同无线接入技术的通信***中,具备基站功能的设备的名称可能会有所不同,例如,LTE***中的基站称之为演进型基站(evolutional node B,eNB)、NR***中的基站(gNB)等。本申请实施例对此不进行不限定。
结合图2,本申请实施例中的终端可以指用户设备(user equipment,UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、终端设备、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例提供的通信方法的流程示意图可以如图3所示,该方法可以包括以下步骤:
步骤301、网络设备向终端发送功耗节省信号,该功耗节省信号指示N个时间单元,N大于0。可选的,N为大于0的整数。
步骤302、终端在接收到该功耗节省信号后,确定在第一频域资源上与上述N个时间单元对应的第一时段内的状态,以及在第二频域资源上与上述N个时间单元对应的第二时段内的状态。
其中,上述状态包括睡眠状态或唤醒状态,睡眠状态表示终端不监测第一信号,唤醒状态表示终端根据配置参数监测第一信号。
网络设备可以向处于唤醒状态的终端发送睡眠信号,则终端根据该睡眠信号确定在第一频域资源上的第一时段内、在第二频域资源上的第二时段内进入睡眠状态。或者,网络设备也可以向处于睡眠状态的终端发送唤醒信号,则终端根据该唤醒信号确定在第一频域资源上的第一时段内、在第二频域资源上的第二时段内进入唤醒状态。又或者,网络设备向终端发送的功耗节省信号中携带状态指示信息,终端根据该指示信息进入何种状态;例如,若该指示信息指示终端进入唤醒状态,则终端在第一频域资源上的第一时段内、在第二频域资源上的第二时段内进入唤醒状态;若该指示信息指示终端进入睡眠状态,则在第一频域资源上的第一时段内、在第二频域资源上的第二时段内进入睡眠状态。
在本申请实施例中,功耗节省信号不限于指示终端是否监测PDCCH,还可以用于指示终端是否监测其他信号,例如,上述第一信号还可以指CSI-RS、SSB等。下述实施例中将以第一信号为PDCCH为例进行详细说明,应当理解,下述实施例中的PDCCH也可以被替换为CSI-RS、SSB等其他信号。
上述频域资源可以为CC,即,第一频域资源为第一CC,第二频域资源为第二CC。进一步的,第一CC可以为主CC,第一CC可以为辅CC。
上述频域资源也可以为BWP,即,第一频域资源为第一BWP,第二频域资源为第二BWP。进一步的,第一BWP可以为主BWP,第二BWP可以为辅BWP。或者第一BWP可以为主CC上BWP,第二BWP可以为辅CC上BWP。其中,BWP有时也可称为载波带宽部分(carrier bandwidth part)、子带(subband)带宽、窄带(narrowband)带宽,或者其他的名称,本申请对此并不做限定。
在一种可能的实现方式中,上述功耗节省信号所指示的N个时间单元可以为N个时隙,或者N个监测时机,或者N个C-DRX周期。下面针对这三种情况分别介绍如何确定第一时段以及第二时段。
一种实施例、N个时隙
如前所述,时隙并非绝对时间单元,一个时隙的绝对时间长度与子载波间隔的大小有关。因此,网络设备在确定N的大小时,需要考虑子载波间隔的大小。
在一种可能的实现方式中,以第一频域资源配置的子载波间隔作为参考子载波间隔,故而网络设备所指示的N个时隙即为第一频域资源上的N个时隙。因此,终端可以直接确定第一时段为第一频域资源上的N个时隙。
终端可以根据第一频域资源配置的子载波间隔、第二频域资源配置的子载波间隔以及N确定第二时 段的时长。
可选地,终端可以根据第一频域资源的子载波间隔、第二频域资源的子载波间隔以及N计算出第二时段的时长。例如,若第一频域资源配置的子载波间隔为15*2M1kHz,第二频域资源配置的子载波间隔为15*2M2kHz,M1、M2为大于等于0的整数;则终端确定第二时段的时长为第二频域资源上的N*2M2-M1个时隙。
例如,CC1的子载波间隔为15kHz,即M1=0,CC2的子载波间隔为30kHz,即M2=1,终端在CC1上和CC2上均每个时隙监测一次PDCCH。功耗节省信号指示终端在此后的4个时隙中不接收PDCCH,则终端确定第一时段的时长为CC1上的4个时隙,确定第二时段的时长为CC2上的N*2M2-M1=4*21-0=8个时隙,如图4所示,终端在第一时段内、在CC1上不再监测PDCCH,在第二时段内、在CC2上不再监测PDCCH。
又例如,CC1的子载波间隔为30kHz,即M1=1,CC2的子载波间隔为15kHz,即,M2=0,终端在CC1上和CC2上均每个时隙监测一次PDCCH。功耗节省信号指示终端在此后的4个时隙中不接收PDCCH,即进入睡眠状态,则终端确定第一时段的时长为CC1上的4个时隙,第二时段的时长为CC2上的N*2M2-M1=4*20-1=2个时隙,如图5所示。
在上述实施例中,若M2≥M1,则第二时段为整数个时隙;若M2<M1,则第二时段为非整数个时隙。由于非整数个时隙增加了终端执行的复杂度,因此,网络设备可以将较小的子载波间隔作为参考子载波间隔,即,将子载波间隔小的资源频域作为第一频域资源,从而使得M2≥M1,保证第二时段为整数个时隙。
例如,CC1的子载波间隔为30kHz,即M1=1,CC2的子载波间隔为15kHz,即M2=0,终端在CC1上和CC2上均每个时隙监测一次PDCCH。功耗节省信号指示终端在此后的5个时隙中不接收PDCCH,即进入睡眠状态,则终端确定第一时段的时长为CC1上的5个时隙,第二时段的时长为CC2上的
个时隙,如图6所示;或者,终端确定第二时段的时长为CC2上的
个时隙,如图7所示。
或者,终端还可以在确定出非整数个时隙时,向网络设备报错。由于终端不期望网络设备所指示的N个时隙对应的第一时段和/或第二时段为非整数个时隙,故而终端可以在确定第一时段和/或第二时段为非整数个时隙时,不执行功耗节省信号指示的进入唤醒状态或进入睡眠状态的操作,并向网络设备报错。另一方面,若网络设备根据预先约定或与终端设备的通信,获取到终端不期望第一时段和/或第二时段为非整数个时隙,则网络设备在发送功耗节省信号之前,可以先根据第一频域资源的子载波间隔、第二频域资源的子载波间隔确定,能够使得第一时段和第二时段均为整数个时隙的N的取值。
应当理解,非整数个时隙虽然为终端操作增加了复杂度,但并非终端无法实现。因此,若第一时段和/或第二时段为非整数个时隙,终端也可以不取整或不报错,而是根据非整数个时隙执行睡眠或唤醒的操作。
例如,CC1的子载波间隔为30kHz,即M1=1,CC2的子载波间隔为15kHz,即M2=0,终端在CC1上和CC2上均每个时隙监测一次PDCCH。功耗节省信号指示终端在此后的5个时隙中不接收PDCCH,即进入睡眠状态,则终端确定第一时段的时长为CC1上的5个时隙,第二时段的时长为CC2上的N*2
M2-M1=2.5个时隙,如图8所示。
可选地,终端可以根据第一频域资源的子载波间隔、第二频域资源的子载波间隔以及N查表确定第 二时段的时长。例如,第一频域资源配置的子载波间隔为15*2M1kHz,第二频域资源配置的子载波间隔为15*2M2kHz,终端中预先配置有如表1所示的第二时段时长对应表。
表1
M1 | M2 | N | X(表示第二时段的时长为第二频域资源上的X个时隙) |
0 | 1 | 1 | 2 |
0 | 1 | 2 | 4 |
… | … | … | … |
0 | 2 | 1 | 4 |
0 | 2 | 2 | 8 |
… | … | … | … |
应当理解,表1中所示的数值仅为举例,并不对本申请构成限定。
进一步的,表1中的第二时长X可以是根据前述实施例中的公式确定出的。
在另一种可能的实现方式中,网络设备可以不以第一频域资源配置的子载波间隔或第二频域资源配置的子载波间隔作为参考子载波间隔。网络设备在向终端发送功耗节省信号之前,可以向终端发送第一配置信息,该第一配置信息包括功耗节省信号的参考子载波间隔。
相应地,终端则根据参考子载波间隔、第一频域资源配置的子载波间隔以及N确定第一时段的时长,根据参考子载波间隔、第二频域资源配置的子载波间隔以及N确定第二时段时长。
可选地,终端还可以根据参考子载波间隔、第一频域资源的子载波间隔以及N计算出第一时段的时长,根据参考子载波间隔、第二频域资源的子载波间隔以及N计算出第二时段的时长。
例如,若参考子载波间隔为15*2M0kHz,第一频域资源配置的子载波间隔为15*2M1kHz,第二频域资源配置的子载波间隔为15*2M2kHz,M0、M1、M2为大于等于0的整数;则终端确定第一时段为第一频域资源上的N*2M1-M0个时隙,第二时段的时长为第二频域资源上的N*2M2-M0个时隙。
若M1≥M0、M2≥M0,则第一时段、第二时段为整数个时隙;若M1<M0、M2<M0,则第一时段、第二时段为非整数个时隙。
如前所述,终端可能不期望第一时段和/或第二时段为非整数个时隙。在一些实施例中,可以令参考子载波间隔小于等于第一频域资源的子载波间隔、令参考子载波间隔小于第二频域资源,即,M1≥M0、M2≥M0,从而保证第一时段和第二时段为整数个时隙。
在另一些实施例中,也可以不对M0、M1、M2的大小进行限定,终端在计算第一时段、计算第二时段时,可以增加取整操作,即,第一时段的时长为第一频域资源上的
个时隙,或者
个时隙;第二时段时长为第二频域资源上的
个时隙,或者
个时隙。
还有一些实施例中,终端也可以在确定第一时段和/或第二时段为非整数个时隙时,向网络设备报错。
另一方面,若网络设备根据预先约定或与终端设备的通信,获取到终端不期望第一时段和/或第二时段为非整数个时隙,则网络设备在发送功耗节省信号之前,可以先根据参考子载波间隔、第一频域资源的子载波间隔、第二频域资源的子载波间隔确定,能够使得第一时段和第二时段均为整数个时隙的N的取值。
当然,终端还可以根据非整数个时隙进行睡眠或唤醒的操作。
可选地,终端可以根据参考子载波间隔、第一频域资源的子载波间隔以及N查表确定第一时段的时长,根据参考子载波间隔、第二频域资源的子载波间隔以及N查表确定第二时段的时长。
例如,假设参考子载波间隔为15*2M0kHz,第一频域资源配置的子载波间隔为15*2M1kHz,终端可以根据表2确定第一时段的时长。
表2
M0 | M1 | N | X(表示第一时段的时长为第一频域资源上的X个时隙) |
0 | 1 | 1 | 2 |
0 | 1 | 2 | 4 |
… | … | … | … |
0 | 2 | 1 | 4 |
0 | 2 | 2 | 8 |
… | … | … | … |
表2中所示的数值仅为举例,并不对本申请构成限定。进一步的,表2中的第一时长X可以是根据前述实施例中的公式确定出的。
终端确定第二时段的时长的方式与确定第一时段的时长的方式类似,此处不再举例。
一般来说,上述所述第一时段和第二时段包含的时隙,均为连续时隙。
另一种实施例、N个监测时机
如图4所示,终端被配置的监测周期为1个时隙,在每个时隙的第一符号上监测PDCCH,即图4中阴影所示部分,每个阴影部分被称为一个监测时机;又如图8所示,在CC1上每2个时隙包含一个监测时机,即终端在CC1上被配置的监测周期为2个时隙,在CC2上每4个时隙包含一个监测时机,即终端在CC2上被配置的监测周期为4个时隙。
由于监测时机并非绝对时间单元,N个监测时机对应的N个监测周期的长度,与监测周期、子载波间隔均有关联,因此,网络设备在确定N的大小时,需要考虑监测周期以及子载波间隔的大小。若网络设备发送的睡眠信号指示N个监测时机,则表示在参考监测周期、参考子载波间隔的情况下,N个监测周期不监测PDCCH;若网络设备发送的唤醒信号指示N个监测时机,则表示在参考监测周期、参考子载波间隔的情况下,终端在N个监测周期中根据配置参数监测PDCCH,即,终端在N个监测周期中的每个监测周期的监测时机监测PDCCH。
在一种可能的实现方式中,可以将第一频域资源配置的子载波间隔作为参考子载波间隔、将终端在第一频域资源配置的监测周期作为参考监测周期,故而网络设备所指示的N个监测时机为终端在第一频域资源上的N个监测时机。因此,终端可以直接根据功耗节省信号确定在第一频域资源上的N个监测时机上监测或不监测PDCCH,即,第一时段为第一频域资源上的N个监测周期。
终端可以根据第一频域资源配置的子载波间隔、在第一频域资源上的监测周期、第二频域资源配置的子载波间隔、在第二频域频域上的监测周期以及N确定第二时段时长。
可选地,终端还可以根据第一频域资源的子载波间隔、在第一频域资源上的监测周期、第二频域资源的子载波间隔、在第二频域资源上的监测周期以及N计算出第二时段时长。例如,若第一频域资源的子载波间隔为15*2M1kHz,第二频域资源的子载波间隔为15*2M2kHz,终端在第一频域资源上的监测周期为L1个时隙,在第二频域资源上的监测周期为L2个时隙,其中,M1、M2为大于等于0的整数,L1、L2为大于等于1的整数;则终端确定第二时段时长为第二频域资源上的
个监测周期。
例如,CC1和CC2的子载波间隔均为15kHz,即M1=M2=0,终端在CC1上每2个时隙监测一次PDCCH,在CC2上每4个时隙监测一次PDCCH。功耗节省信号指示终端在此后的4个监测时机中不接收PDCCH,则终端确定第一时段的时长为CC1上的4个监测时机对应的4个监测周期,即8个时隙,确定第二时段 的时长为CC2上的
个监测时机对应的2个监测周期,即8个时隙,如图9所示。
又例如,CC1和CC2的子载波间隔均为15kHz,即M1=M2=0,终端在CC1上每4个时隙监测一次PDCCH,在CC2上每2个时隙监测一次PDCCH。功耗节省信号指示终端在此后的1个监测时机中不接收PDCCH,则终端确定第一时段的时长为CC1上的1个监测时机对应的1个监测周期,即4个时隙,确定第二时段的时长为CC2上的
个监测时机对应的2个监测周期,即4个时隙,如图10所示。
终端可能不期望确定出的第二时段为非整数个监测周期,可选地,终端还可以在计算第二时段时,增加取整操作,即,第二时段时长为第二频域资源上的
个监测周期,或者
个监测周期,从而使得第二时段的时长为整数个监测周期。
例如,CC1和CC2的子载波间隔均为15kHz,即M1=M2=0,终端在CC1上每2个时隙监测一次PDCCH,在CC2上每3个时隙监测一次PDCCH。耗节省信号指示终端在此后的2个监测时机中不接收PDCCH,则终端确定第一时段的时长为CC1上的2个监测时机对应的2个监测周期,即4个时隙,确定第二时段的时长为CC2上的
个监测时机对应的2个监测周期,即6个时隙。如图11所示,由于CC2与CC1的监测周期不同,因此,在接收到功耗节省信号之后,CC2的第一个监测时机与CC1的第一个监测时机可能存在三种情况:CC2的第一个监测时机可能与CC1的第一个监测时机一致,如图10中第二行所示的CC2;或者,CC2的第一个监测时机比CC1的监测时机晚了2个时隙,如图11中第三行所示的CC2;或者,CC2的第一个监测时机比CC1的监测时机晚了1个时隙,如图11中第四行所示的CC2。
或者,终端确定第二时段的时长为CC2上的
个监测时机对应的1个监测周期,即3个时隙。如图12所示,由于CC2与CC1的监测周期不同,因此,在接收到功耗节省信号之后,CC2的第一个监测时机与CC1的第一个监测时机可能存在三种情况:CC2的第一个监测时机可能与CC1的第一个监测时机一致,如图12中第二行所示的CC2;或者,CC2的第一个监测时机比CC1的监测时机晚了2个时隙,如图12中第三行所示的CC2;或者,CC2的第一个监测时机比CC1的监测时机晚了1个时隙,如图12中第四行所示的CC2。
此外,如终端不期望第二时段为非整数个监测周期,还可以在确定出非整数个监测周期时,向网络设备报错。另一方面,若网络设备根据预先约定或与终端设备的通信,获取到终端不期望第一时段和/或第二时段为非整数个监测周期,则网络设备在发送功耗节省信号之前,可以先根据第一频域资源的子载波间隔和监测周期、第二频域资源的子载波间隔和监测周期确定,能够使得第一时段和第二时段均为整数个时隙的N的取值。
在上述终端确定第一时段时长、第二时段时长的方式中,以第一时段时长、第二时段时长的单位为监测周期进行举例说明,然而,终端还可以确定第一时段包含的时隙数量以及第二时段包含的时隙数量。例如,终端确定第一时段的时长为第一频域资源上的N*L1个时隙,第二时段的时长为第二频域资源上的N*L1*2
M2-M1个时隙,或者
个时隙,或者
个时隙。
例如,CC1和CC2的子载波间隔均为15kHz,即M1=M2=0,终端在CC1上每2个时隙监测一次PDCCH,在CC2上每3个时隙监测一次PDCCH。耗节省信号指示终端在此后的2个监测时机中不接收PDCCH,则终端确定第一时段的时长为CC1上的N*L1=2*2=4,确定第二时段的时长为CC2上的N*L1*2
M2-M1=2*2*2
1-1=4时隙。如图13所示,由于CC2与CC1的监测周期不同,因此,在接收到功耗节省信号之后,CC2的第一个监测时机与CC1的第一个监测时机可能存在三种情况:CC2的第一个监测时机可能 与CC1的第一个监测时机一致,如图13中第二行所示的CC2,第二时段包含了2个监测时机;或者,CC2的第一个监测时机比CC1的监测时机晚了2个时隙,如图13中第三行所示的CC2,第二时段包含了1个监测时机;或者,CC2的第一个监测时机比CC1的监测时机晚了1个时隙,如图13中第四行所示的CC2,第二时段包含了1个监测时机。
在以时隙为单位的上述实施例中,在不进行取整操作时,若M2≥M1,则第二时段为整数个时隙;若M2<M1,则第二时段为非整数个时隙。由于终端可能不期望非整数个时隙,故可以将较小的子载波间隔作为参考子载波间隔,即,将子载波间隔小的资源频域作为第一频域资源,从而使得M2≥M1。
应当理解,非整数个监测周期或非整数个时隙虽然为终端操作增加了复杂度,但并非终端无法实现。因此,若第一时段和/或第二时段为非整数个监测周期或非整数个时隙,终端也可以不取整或不报错,而是根据非整数个时隙执行睡眠或唤醒的操作。
可选地,终端可以根据第一频域资源的子载波间隔、在第一频域资源上的监测周期、第二频域资源的子载波间隔、在第二频域资源上的监测周期以及N查表确定第二时段时长。例如,第一频域资源的子载波间隔为15*2M1kHz,第二频域资源的子载波间隔为15*2M2kHz,终端在第一频域资源上的监测周期为L1个时隙,在第二频域资源上的监测周期为L2个时隙,其中,M1、M2为大于等于0的整数,L1、L2为大于等于1的整数,终端可以根据表3确定第二时段的时长。
表3
应当理解,表3中所示的数值仅为举例,并不对本申请构成限定。
在另一种可能的实现方式中,网络设备也可以不将第一频域资源的子载波间隔作为参考子载波间隔、不将终端在第一频域资源上的监测周期作为参考监测周期。网络设备在向终端发送功耗节省信息后之前,可以向终端发送第二配置信息,该第二配置信息包括功耗节省信号的参考子载波间隔以及参考监测周期。
相应地,终端根据参考子载波间隔、参考监测周期、第一频域资源的子载波间隔、终端在第一频域资源上的监测周期以及N确定第一时段的时长;根据参考子载波间隔、参考监测周期、第二频域资源的子载波间隔、终端在第二频域资源上的监测周期以及N确定第二时段的时长。
可选地,终端还可以根据参考子载波间隔、参考监测周期、第一频域资源的子载波间隔、在第一频域资源上的监测周期以及N计算出第一时段时长;根据参考子载波间隔、参考监测周期、第二频域资源的子载波间隔、在第二频域资源上的监测周期以及N计算出第二时段时长。
例如,若参考子载波间隔为15*2M0kHz,参考监测周期为L0个时隙,第一频域资源配置的子载波间隔为15*2M1kHz,终端在第一频域资源上的监测周期为L1个时隙,其中,M0、M1为大于等于0的整数,L0、L1为大于等于1的整数。则终端确定第一时段的时长为第一频域资源上的
个监测周期,或者
个监测周期,或者
个监测周期,或者N*L0*2
M1-M0个时隙, 或者
个时隙,或者
个时隙;第二时段的时长为第二频域资源上的
个监测周期,或者
个监测周期,或者
个监测周期,或者N*L0*2
M2-M0个时隙,或者
个时隙,或者
个时隙。
若M1≥M0、M2≥M0,则第一时段、第二时段为整数个时隙;若M1<M0、M2<M0,则第一时段、第二时段为非整数个时隙。如前所述,终端可能不期望第一时段和/或第二时段为非整数个时隙。在一些实施例中,可以令参考子载波间隔小于等于第一频域资源的子载波间隔、令参考子载波间隔小于第二频域资源,即,M1≥M0、M2≥M0,从而保证第一时段和第二时段为整数个时隙。
或者,终端也可以在确定第一时段和/或第二时段为非整数个监测周期,或者为非整数个时隙时,向网络设备报错。另一方面,若网络设备根据预先约定或与终端设备的通信,获取到终端不期望第一时段和/或第二时段为非整数个周期,或者非整数个时隙,则网络设备在发送功耗节省信号之前,可以先根据参考子载波间隔、参考监测周期、第一频域资源的子载波间隔、在第一频域资源上的监测周期、第二频域资源的子载波间隔、在第二频域资源上的监测周期确定,能够使得第一时段和第二时段均为整数个监测周期的N的取值,或者时段第一时段和第二时段均为非整数个时隙的N的取值。
当然,终端还可以根据非整数个监测周期或非整数个时隙进行睡眠或唤醒的操作。
可选地,终端可以根据上述信息查表确定第一时段的时长以及第二时段的时长。例如,设参考子载波间隔为15*2M0kHz,参考监测周期为L0个时隙,第一频域资源配置的子载波间隔为15*2M1kHz,终端在第一频域资源上的监测周期为L1个时隙,其中,M0、M1为大于等于0的整数,L0、L1为大于等于1的整数,终端可以根据表4根据确定第一时段时长为W监测周期,或者根据表5确定第一时段时长为Z个时隙。
表4
表5
应当理解,表4、表5中所示的数值仅为举例,并不对本申请构成限定。
终端确定第二时段的时长的方式与确定第一时段的时长的方式类似,此处不再举例。
一般来说,上述所述第一时段和第二时段包含的时隙,均为连续时隙。
再一种实施例、N个C-DRX周期
在LTE和NR中,都定义了C-DRX的概念,具体的,处于RRC连接态(RRC_connected)的终端可以被配置C-DRX周期(C-DRX cycle)。如图14所示,C-DRX周期由激活期(on duration)和休眠期(opportunity for DRX)组成,在激活期内,终端监测并接收PDCCH;在休眠期内,UE不接收PDCCH以减少功耗。其中,C-DRX周期大小,以及激活期和休眠期的长度,均可以由网络设备配置给终端。
网络设备给终端配置C-DRX周期时,在CA的场景下,可以为不同CC配置不同的C-DRX参数,在BWP场景下,可以为不同BWP配置不同的C-DRX参数,即,不同CC或不同BWP上的C-DRX周期可能不同。
在本申请实施例中,网络设备可以在为终端在不同频域资源上配置了C-DRX参数后,进一步根据需求,再向终端发送功耗节省信号,网络设备发送的功耗节省信号可以指示为N个C-DRX周期
由于N个C-DRX周期的长度与一个C-DRX周期的长度有关,因此,网络设备在确定N的大小时,需要考虑一个C-DRX周期的长度,即,根据参考C-DRX周期确定N的取值。
在一种可能的实现方式中,可以将第一频域资源上的C-DRX周期作为参考C-DRX周期,故而网络设备所指示的N个C-DRX周期为第一频域资源上的N个C-DRX周期。因此,终端可以直接确定第一时段为第一频域资源上的N个C-DRX周期。
终端可以根据第一频域上的C-DRX周期、第二频域资源上的C-DRX周期以及N确定第二时段的时长。
可选地,终端还可以根据第一频域资源的C-DRX周期、第二频域资源的C-DRX周期以及N计算出第二时段的时长。例如若第一频域资源上的C-DRX周期为K1个绝对时间单元,第二频域资源上的C-DRX周期为K2个绝对时间单元,K1、K2为的大于等于1的整数;则终端确定第二时段的时长为第二频域资源上的N*K1/K2个C-DRX周期。
在上述终端确定第一时段时长、第二时段时长的方式中,以第一时段时长、第二时段时长的单位为C-DRX周期进行举例说明,此外,终端还可以确定第一时段和第二时段包含的绝对时段单元的数量。例如,终端确定第一时段的时长和第二时段时长均为N*K1个绝对时间的单元。
可选地,终端可以根据第一频域资源上的C-DRX周期、第二频域资源上的C-DRX周期以及N查表确定第二时段的时长。例如,第一频域资源上的C-DRX周期为K1个绝对时间单元,第二频域资源上的C-DRX周期为K2个绝对时间单元,其中,绝对时间单元可以为毫秒(ms)、秒(s)等,K1、K2为大于等于1的整数;终端可以根据表6或表7确定第二时段的时长。
表6
应当理解,表6中所示的数值仅为举例,并不对本申请构成限定。
在另一种可能的实现方式中,网络设备也可以不将第一频域资源上的C-DRX周期作为参考C-DRX周期。网络设备在向终端发送功耗节省信号之前,可以向终端发送第三配置信息,该第三配置信息包括参考C-DRX周期为K0个绝对时间单元。
相应地,终端则根据参考C-DRX周期、第一频域资源上的C-DRX周期以及N确定第一时段的时长,根据参考C-DRX周期、第二频域资源上的C-DRX周期以及N确定第二时段的时长。
可选地,终端还可以根据参考C-DRX周期、第一频域资源上的C-DRX周期以及N计算出第一时段的时长;根据参考C-DRX周期、第二频域资源上的C-DRX周期以及N计算出第二时段的时长。
例如,若参考C-DRX周期为K0个绝对时间单元,第一频域资源的C-DRX周期为K1个绝对时间单元,第二频域资源上的C-DRX周期为K2个绝对时间单元,其中,K0、K1、K2位大于等于1的整数。则终端确定第一时段的时长为第一频域资源上的N*K0/K1个C-DRX周期,第二时段的时长为第二频域资源上的N*K0/K2个C-DRX周期;或者,终端还可以确定第一时段和第二时段的时长均为N*K0个绝对时间单元。
在一些实施例中,终端可能不期望第一时段、第二时段的时长为非整数个C-DRX周期,因此,若终端确定出第一时段和/或第二时段的时长为非整数个C-DRX周期时,可以向网络设备报错。另一方面,若网络设备根据预先约定或与中能够的的通信,获取到终端不期望第一时段和/或第二时段为非整数个C-DRX周期,则网络设备在发送功耗节省信号之前,可以向根据参考C-DRX周期、第一频域资源上的C-DRX周期、第二频域资源上的C-DRX周期确定,能够使得第一时段和第二时段均为整数个C-DRX周期的N的取值。
可选地,终端可以根据参考C-DRX周期、第一频域资源上的C-DRX周期以及N查表确定第一时段的时长。例如,假设参考C-DRX周期为K0个绝对时间单元,第一频域资源上的C-DRX周期为K1个绝对时间单元,终端可以根据表7确定第一时段的时长为B个C-DRX周期,或者根据表8确定第一时段的时长为C个绝对时间单元。

应当理解,表7、表8中所示的数值仅为举例,并不对本申请构成限定。
终端确定第二时段的时长的方式与确定第一时段的时长的方式类似,此处不再举例。
上面针对三种情况分别介绍了确定第一时段和第二时段的时长的方式,而终端在根据功耗节省信号进行休眠或唤醒操作、网络设备确定是否可以向终端发送第一信号时,还应当确定第一时段和第二时段的起始时间。具体地,第一时段和第二时段的起始时间的确定方式,可以包括以下四种方式:
方式一、
终端可以将接收到功耗节省信号之后的、在第一频域资源上的第一个时隙作为第一时段的起始时间,将接收到功耗节省信号之后的、在第二频域资源上的第一个时隙作为第二时隙的起始时间。对于网络设备来说,则可以将发送功耗节省信号之后的、在第一频域资源上的第一个时隙作为第一时段的起始时间,将发送功耗节省信号之后的,在第二频域资源上的第一个时隙作为第二时隙的起始时间,如图4至图7所示。
或者,终端也可以将接收到功耗节省信号的时隙作为第一时段、第二时段的起始时间。相应的,网络设备则将发送功耗节省信号的时隙作为第一时段、第二时段的起始时间,如图15所示。
该确定第一时段、第二时段起始时间的方式一,对于上述情况一、情况二、情况三均可适用。
方式二、
当功耗节省信号指示的N个时间单元为N个监测时机时,终端可以将接收到功耗节省信号之后的、在第一频域资源上的第一个监测时机作为第一时段的起始时间,将接收到功耗节省信号之后的、在第二频域资源上的第一个监测时机作为第二时段的起始时间。对于网络设备来说,则可以将发送功耗节省信号之后的、在第一频域资源上的第一个监测时机作为第一时段的起始时间,将发送功耗节省信号之后的,在第二频域资源上的第一个监测时机作为第二时段的起始时间,如图9至图12所示。
方式三、
当功耗节省信号指示的N个时间单元为N个C-DRX周期时,终端可以将接收到功耗节省信号之后的、在第一频域资源上的下一个C-DRX的起始时间作为第一时段的起始时间,将接收到功耗节省信号之后的、在第二频域资源上的下一个C-DRX的起始时间作为第二时段的起始时间。对于网络设备来说,则可以将发送功耗节省信号之后的、在第一频域资源上的下一个C-DRX的起始时间作为第一时段的起始时间,将发送功耗节省信号之后的,在第二频域资源上的下一个C-DRX的起始时间作为第二时段的起始时间。
其中,C-DRX的起始时间,可以指一个C-DRX周期的起始时间,也可以指C-DRX周期中激活期的起始时间。
方式四、
如前所述,功耗节省信号可以携带在DCI信令中发送给终端,携带有功耗节省信号的DCI可以是功耗节省信号专用的DCI,或者,该DCI除了携带有功耗节省信号外,还携带有用于调度上行数据或下行数据的调度信息。当功耗节省信号与调度信息复用一个DCI时,终端和网络设备则先根据调度信息完成上行数据或下行数据的传输,然后终端再进入睡眠状态。
在一种可能的实现方式中,若DCI中包括功耗节省信号以及下行数据(或上行数据)的调度信息,则终端先根据该DCI接收网络设备发送的下行数据(或向网络设备发送上行数据),然后再进入睡眠状态,此时,终端可以将下行数据(或上行数据)的最后一个符号之后的第一个符号或第一个时隙作为第一时段(和/或第二时段)的起始时间,如图16所示。
在另一种可能的实现方式中,网络设备与终端在进行通信时,可以引入混合自动重传请求(hybrid automatic repeat request,HARQ)机制。终端在接收到下行数据后,向网络设备返回确认帧(ACK/NACK),表示终端是否成功接收了下行数据,若接收失败,则网络设备可以重新发送调度信息并重新发送下行数据;终端在向网络设备发送上行数据之后,若网络设备接收失败,可以再次向终端发送调度信息,以使终端重新发送上行数据,如图17所示。
若DCI调度的为下行数据,终端可以将接收到功耗节省信号(DCI)的时隙作为第一时段的起始时间;或者,可以将终端接收下行数据的最后一个符号之后的第一个符号或第一个时隙作为第一时段的起始时间;或者,也可以将终端发送ACK/NACK之后的第一个符号或第一个时隙作为第一时段的起始时间;或者,还可以在终端发送ACK/NACK之后等待预设时长,且该预设时长内终端没接收到网络设备的调度信息,即不必进行重传,终端再开始进入睡眠状态。
具体地,若终端将接收到功耗节省信号(DCI)的时隙作为第一时段的起始时间,由于终端还需要根据DCI接收下行数据并反馈ACK/NACK,再等待一段预设时长以确定不会进行重传,然后才能真正进入睡眠状态。例如,如图18所示,终端在时隙0中接收到DCI,该DCI中包括下行数据的调度信息以及功耗节省信号,指示终端在时隙0中接收下行数据、在此后的5个时隙中可进入睡眠状态。终端确定时隙0为第一时段的起始时间,第一时段的时长为5个时隙(即,时隙0~时隙4);终端在时隙0中接收下行数据,并在时隙1上反馈ACK/NACK,假设预设时长为2个时隙,若终端在反馈ACK/NACK之后的2个时隙(即时隙2和时隙3)中没有接收到网络设备发送的调度信息,则从时隙4开始进入睡眠状态。
若终端将接收下行数据的最后一个符号之后的第一个符号或第一个时隙作为第一时段的起始时间,由于终端还需要反馈ACK/NACK并等待一段预设时长,然后才能正在进入睡眠状态。例如,如图18所示,终端在时隙0中接收到DCI,该DCI中包括下行数据的调度信息以及功耗节省信号,指示终端在时隙0中接收下行数据、在此后的5个时隙中可进入睡眠状态。终端确定时隙1为第一时段的起始时间,第一时段的时长为5个时隙(即,时隙1~时隙5);终端在时隙1上反馈ACK/NACK,假设预设时长为2个时隙,若终端在反馈ACK/NACK之后的2个时隙(即时隙2和时隙3)中没有接收到网络设备发送的调度信息,则从时隙4开始进入睡眠状态,即终端在时隙4、时隙5上处于睡眠状态。
若终端将发送ACK/NACK之后的第一个符号或第一个时隙作为第一时段的起始时间,终端还需要等待预设时长,在网络设备没有重新发送调度信息时,才能真正进入睡眠状态。例如,如图18所示,终端在时隙0中接收到DCI,在时隙0上接收下行数据,在时隙1上反馈ACK/NACK,终端可以将时隙2作为第一时段的起始时间,假设预设时长为2个时隙,若终端在反馈ACK/NACK之后的2个时隙(即时隙2和时隙3)中没有接收到网络设备发送的调度信息,则从时隙4开始进入睡眠状态,即终端在时隙4~时隙6上处于睡眠状态。
若终端在反馈ACK/NACK并等待预设时长后,再开启第一时段的计时,则第一时段即为终端真正进入睡眠状态的时段。例如,如图18所示,终端在时隙0中接收到DCI,该DCI中包括下行数据的调度信息以及功耗节省信号,指示终端在时隙0中接收下行数据、在此后的5个时隙中可进入睡眠状态。终端在时隙0上接收下行数据,在时隙1上反馈ACK/NACK,假设预设时长为2个时隙,若终端在反馈ACK/NACK之后的2个时隙(即时隙2和时隙3)中没有接收到网络设备发送的调度信息,则将时隙4作为第一时段的起始时间,即终端在时隙4~时隙8上处于睡眠状态。
另一方面,若DCI调度的为上行数据,终端可以在接收到功耗节省信号(DCI)的时隙作为第一时段的起始时间,或者,也可以将终端发送上行数据的最后一个符号之后的第一个符号或第一个时隙作为第一时段的起始时间,或者,还可以在发送上行数据之后等待预设时长,且该预设时长内终端没有接收到网络设备的调度信息,即不必进行重传,终端再开始进入睡眠状态。与DCI调度下行数据的情况类似, 此处不再赘述。
上述预设时长可以为网络设备配置给所述终端的。
方式五、
第一时段的起始时间可以为上述方式一至方式四中的任意一种,而第二时段的起始时间与第一时段的起始时间相同。
例如,如图8b所示,终端确定第一时段的起始时间为接收到功耗节省信号之后、在CC1上的第一个时隙或第一个监测时机,并且,终端将第一时段的起始时间作为第二时段的起始时间,此时在CC2上处于一个时隙的中间位置,该位置也不是监测时机。
不论采用上述哪种方式确定第一时段、第二时段起始时间,终端和网络设备需要根据预先约定,或者根据终端与网络设备之间的通信,采用相同方式确定起始时间。
在上述实施例中,终端在接收到功耗节省信号后,确定该信号指示的N个时间单元在不同频域资源上对应的时段,而不是简单的确定在不同的频域资源上在不同频域资源上睡眠时间或唤醒时间均为N个时间单元。由于令终端在不同频域资源上的状态趋近同步,有助于功耗的节省。
基于相同的技术构思,本申请实施例还提供了一种通信方法,该通信方法包括:
网络设备向终端发送功耗节省信号,该功耗节省信号指示N个时间单元,N为大于0的数。终端确定该终端在第一频域资源上与N个时间单元对应的第一时段内的状态,以及在第二频域资源上与N个时间单元对应的第二时段内的状态。其中,终端的状态包括睡眠状态和唤醒状态,睡眠状态表示终端不进行测量,唤醒状态表示终端根据配置参数进行测量。
例如,终端接收网络设备发送的CSI-RS,然后根据该CSI-RS进行信道状态测量,并根据网络设备的配置或指示信息,将测量结果反馈给基站,以使基站根据测量结果对该终端的数据调度进行优化。若终端接收到网络设备发送的功耗节省信号,指示终端进入睡眠状态,则终端确定第一频域资源上的第一时段不再进行信道状态测量、确定第二频域资源上的第二时段不再进行信道状态测量。
可选地,终端在进入睡眠状态后不再进行测量,可以指终端不接收CSI-RS,或者,也可以指终端接收CSI-RS但不对该CSI-RS进行处理。
第一时段的时长、起始时间,以及第二时段的时长、起始时间的确定方法,与前述实施例类似,此处不再一一赘述。
基于相同的技术构思,本申请实施例还提供了一种终端,用于实现上述方法实施例中终端所执行的功能。如图19所示,该终端可以包括接收单元1901和处理单元1902。其中,接收单元1901用于实现上述方法实施例中的接收功耗节省信号以及监测第一信号,处理单元1902用于执行上述方法实施例中终端的其他功能。

以上这些单元可以是被配置成实施以上方法的一个或多个集成电路,例如:一个或多个特定集成电路(application specific integrated circuit,ASIC),或,一个或多个微处理器,或,一个或者多个现场可编程门阵列(field programmable gate array,FPGA)等。再如,当以上某个单元通过处理元件调度程序的形式实现时,该处理元件可以是通用处理器,例如中央处理器(central processing unit,CPU)或其它可以调用程序的处理器。再如,这些单元可以集成在一起,以片上***(system-on-a-chip,SOC)的形式实现。
基于相同的技术构思,本申请实施例还提供了一种通信设备,用于实现上述方法实施例中终端的功能。如图21所示,该通信设备2100可以包括处理器2101和通信接口2102。进一步地,通信设备2100还可以包括存储器2103、通信总线2104。
