具体实施方式Detailed ways
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。In order to make the purpose, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.
首先,对本申请实施例中涉及的名词进行简单介绍:First, briefly introduce the terms involved in the embodiments of this application:
非连续接收(Discontinuous Reception,DRX):DRX可以让终端周期性的在某些时候进入休眠期,不去监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度信息(或称PDCCH子帧)。而在终端需要监听PDCCH调度信息的时候,则从休眠期中唤醒(wake up),这样就可以使终端达到省电的目的。Discontinuous Reception (DRX): DRX allows the terminal to periodically enter a dormant period at certain times without monitoring the physical Downlink Control Channel (PDCCH) scheduling information (or PDCCH subframe). When the terminal needs to monitor the PDCCH scheduling information, it wakes up from the dormant period, so that the terminal can achieve the purpose of saving power.
DRX的基本机制是为处于无线资源控制连接态(Radio Resource Control_CONNECTED,RRC_CONNECTED)态的终端配置一个DRX周期(DRX cycle)。DRX周期由“激活期(Active Time)”和“休眠期(Inactive Time)”组成:在“激活期”的时间内,终端监听并接收PDCCH调度信息;在“休眠期”时间内,终端不接收下行信道的数据以节省功耗。从图1可以看出,在时域上,时间被划分成一个个连续的DRX周期(Cycle)。当终端在“激活期”期间收到一个调度消息时,终端会启动一个DRX的非活跃态定时器(DRX-Inactivity Timer)并在该期间的每一个子帧监听PDCCH调度信息;如果DRX-Inactivity Timer正在运行,那么即便原本配置的On Duration时间已经结束,终端仍然需要继续监听下行的PDCCH子帧,直到DRX-Inactivity Timer的超时。The basic mechanism of DRX is to configure a DRX cycle (DRX cycle) for the terminal in the radio resource control connected state (Radio Resource Control_CONNECTED, RRC_CONNECTED) state. The DRX cycle is composed of "Active Time" and "Inactive Time": during the "active period", the terminal monitors and receives PDCCH scheduling information; during the "sleep period", the terminal does not receive it Downlink channel data to save power consumption. As can be seen from Figure 1, in the time domain, time is divided into successive DRX cycles (Cycle). When the terminal receives a scheduling message during the "active period", the terminal will start a DRX-Inactivity Timer (DRX-Inactivity Timer) and monitor the PDCCH scheduling information in each subframe of the period; if DRX-Inactivity The Timer is running, so even if the originally configured OnDuration time has expired, the terminal still needs to continue to monitor the downlink PDCCH subframes until the DRX-Inactivity Timer expires.
载波聚合:载波聚合(Carrier Aggregation,CA)是将2个或更多的分量载波(Component Carrier,CC)聚合在一起以支持更大的传输带宽。如图2所示,CA技术可以将2~5个载波聚合在一起,实现最大100MHz的传输带宽,有效提高了上下行传输速率。Carrier aggregation: Carrier Aggregation (CA) is the aggregation of 2 or more component carriers (Component Carrier, CC) to support a larger transmission bandwidth. As shown in Figure 2, CA technology can aggregate 2 to 5 carriers to achieve a maximum transmission bandwidth of 100 MHz, which effectively improves the uplink and downlink transmission rates.
主小区(Primary Cell,PCell)是终端进行初始连接建立的小区,或进行RRC连接重建的小区,或是在小区切换过程中指定的主小区。PCell负责与终端之间的无线资源控制(Radio Resource Control,RRC)通信。PCell对应的载波单元称为主载波(Primary Component Carrier,PCC)。A primary cell (Primary Cell, PCell) is a cell where a terminal establishes an initial connection, or a cell where an RRC connection is reestablished, or a primary cell designated during a cell handover. PCell is responsible for radio resource control (Radio Resource Control, RRC) communication with the terminal. The carrier unit corresponding to PCell is called Primary Component Carrier (PCC).
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,SCell与终端之间不存在任何RRC通信。SCell对应的载波单元称为辅助载波(Secondary Component Carrier,SCC)。A secondary cell (Secondary Cell, SCell) is added during RRC reconfiguration and is used to provide additional radio resources. There is no RRC communication between the SCell and the terminal. The carrier unit corresponding to the SCell is called a secondary carrier (Secondary Component Carrier, SCC).
同一时刻只存在一个主载波,允许存在多个辅助载波,比如3个辅助载波。网络可以根据需要将暂不使用的辅助载波设置为睡眠状态,降低终端功耗;也可以快速激活辅助载波,使得辅助载波处于非睡眠状态以满足传输需要。终端的主载波不能被去激活;终端只能在激活的载波(主载波或辅助载波)上进行数据传输,在去激活的载波(辅助载波)上只支持有限度的测量。There is only one primary carrier at the same time, and multiple secondary carriers are allowed, such as 3 secondary carriers. The network can set the auxiliary carrier that is not in use temporarily to a sleep state as needed to reduce the power consumption of the terminal; it can also quickly activate the auxiliary carrier so that the auxiliary carrier is in a non-sleep state to meet transmission needs. The main carrier of the terminal cannot be deactivated; the terminal can only transmit data on the activated carrier (main carrier or auxiliary carrier), and only supports limited measurement on the deactivated carrier (secondary carrier).
睡眠模式:在睡眠模式下,终端可以忽略掉一个载波的PDCCH或者大幅度减少一个载波上的PDCCH监控。同时,终端只需要保持一些基本的信道测量类的信号接收,如上下行 同步,以及频率校准。Sleep mode: In the sleep mode, the terminal can ignore the PDCCH of one carrier or greatly reduce the PDCCH monitoring on one carrier. At the same time, the terminal only needs to maintain some basic channel measurement signal reception, such as uplink and downlink synchronization, and frequency calibration.
NR调整辅助载波的睡眠状态的机制是:通过切换到睡眠带宽部分(Bandwidth Part,BWP)或者非睡眠BWP,相应地,使得某个辅助载波进入到睡眠状态或者非睡眠状态。具体地,终端在某一时隙接收网络设备通过主载波发送的PDCCH,终端根据PDCCH承载的下行控制信息(Downlink Control Information,DCI)中的指示域的指示,确定辅助载波的状态,进而切换到睡眠BWP或者非睡眠BWP。如图3所示,睡眠载波/BWP的功耗可以大幅度降低。如图3中的(a)示出的非睡眠载波/BWP,大部分时隙会有用于进行PDCCH监控、物理下行共享信道(Physical Downlink Shared Channel,PDSCH)缓存以及测量等的功耗。如图3中的(b)示出的睡眠载波/BWP,在某些时隙仅会有用于测量的功耗,从而实现终端功耗的降低。The mechanism for NR to adjust the sleep state of the auxiliary carrier is: by switching to the sleep bandwidth part (Bandwidth Part, BWP) or non-sleep BWP, correspondingly, a certain auxiliary carrier enters the sleep state or the non-sleep state. Specifically, the terminal receives the PDCCH sent by the network device through the primary carrier in a certain time slot, and the terminal determines the status of the secondary carrier according to the indication field in the Downlink Control Information (DCI) carried by the PDCCH, and then switches to sleep BWP or non-sleeping BWP. As shown in Figure 3, the power consumption of the sleep carrier/BWP can be greatly reduced. For the non-sleeping carrier/BWP as shown in (a) in FIG. 3, most time slots will have power consumption for PDCCH monitoring, physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) buffering, and measurement. In the sleep carrier/BWP shown in (b) of Fig. 3, there is only power consumption for measurement in some time slots, so as to reduce the power consumption of the terminal.
相关技术中,存在两种可能性的辅助载波的睡眠指示方法。当DCI是非调度(即无调度数据)的DCI时,则终端将DCI中的n个比特作为指示域,用于指示辅助载波的睡眠状态,n为正整数,例如:n为15。当DCI是调度(即调度数据)的DCI时,则终端将使用DCI中的专用指示域,来确定辅助载波组的睡眠状态。In the related art, there are two possible sleep indication methods for the auxiliary carrier. When the DCI is a non-scheduled (that is, no scheduled data) DCI, the terminal uses n bits in the DCI as an indicator field to indicate the sleep state of the auxiliary carrier, and n is a positive integer, for example, n is 15. When the DCI is scheduled (that is, scheduled data) DCI, the terminal will use the dedicated indication field in the DCI to determine the sleep state of the auxiliary carrier group.
相关技术中,终端只能使用一种辅助载波的睡眠指示方法。当终端接收到的DCI配置有对应于多种辅助载波的睡眠指示方法的指示域时,终端如何确定辅助载波的睡眠状态,相关技术尚未提供较好的解决方案。In the related art, the terminal can only use one sleep indication method of the auxiliary carrier. When the DCI received by the terminal is configured with indication fields corresponding to the sleep indication methods of multiple auxiliary carriers, how the terminal determines the sleep state of the auxiliary carrier, the related technology has not yet provided a better solution.
DCI格式:PDCCH可以承载多种不同的DCI格式。本申请中的DCI的格式可以是DCI格式0-1或DCI格式1-1(详见第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)标准38212-g00),如表一和表二所示:DCI format: PDCCH can carry many different DCI formats. The DCI format in this application can be DCI format 0-1 or DCI format 1-1 (see the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) standard 38212-g00 for details), as shown in Tables 1 and 2 Show:

The method may be applied to the terminal 13 shown in FIG. 1. This embodiment can be implemented alone or in combination with the embodiment shown in FIG. 5 or FIG. 9. The method includes:
步骤1010,根据DCI中的频域资源指示域,确定DCI是否是无数据调度的DCI。Step 1010: Determine whether the DCI is a DCI without data scheduling according to the frequency domain resource indication field in the DCI.
其中,DCI是第一DCI或第二DCI。Wherein, DCI is the first DCI or the second DCI.
频域资源指示(Frequency Domain Resource Allocation,FDRA)域是DCI中的信息域之一。在上行调度授权DCI(如表一示出的DCI格式0-1)中,该信息域用于指示在一个分量载波上为终端发送物理上行共享信道(Physical Uplink Shared Channel,PDSCH)所分配的资源块。在下行调度授权DCI(如表二示出的DCI格式1-1)中,该信息域用于指示终端需要接收的PDSCH分配在分量载波的哪些资源块上。其中,分量载波是载波聚合场景下聚合的其中一个载波。The Frequency Domain Resource Allocation (FDRA) field is one of the information fields in the DCI. In the uplink scheduling authorization DCI (such as the DCI format 0-1 shown in Table 1), this information field is used to indicate the resources allocated for the terminal to transmit the physical uplink shared channel (PDSCH) on a component carrier Piece. In the downlink scheduling grant DCI (such as the DCI format 1-1 shown in Table 2), this information field is used to indicate which resource blocks of the component carrier the PDSCH that the terminal needs to receive is allocated on. Among them, the component carrier is one of the carriers aggregated in the carrier aggregation scenario.
终端通过DCI中的FDRA域,确定出该DCI是否是无数据调度的DCI。The terminal determines whether the DCI is a DCI without data scheduling through the FDRA field in the DCI.
在一种可能的实现方式中,在与辅助载波对应的BWP的资源分配类型是第一类型,且频域资源指示域中的比特位全为0的情况下,终端确定DCI是无数据调度的DCI。In a possible implementation manner, when the resource allocation type of the BWP corresponding to the secondary carrier is the first type, and the bits in the frequency domain resource indicator field are all 0, the terminal determines that the DCI is scheduled without data. DCI.
在另一种可能的实现方式中,在与辅助载波对应的BWP的资源分配类型是第二类型,且频域资源指示域中的比特位全为1的情况下,终端确定DCI是无数据调度的DCI。In another possible implementation manner, when the resource allocation type of the BWP corresponding to the secondary carrier is the second type, and the bits in the frequency domain resource indicator field are all 1, the terminal determines that the DCI is dataless scheduling DCI.
其中,第一类型和第二类型是两种不同的资源分配类型,第一类型是一种基于位图进行分配的模式,而第二类型不依赖于位图。Among them, the first type and the second type are two different resource allocation types, the first type is a mode of allocation based on a bitmap, and the second type does not depend on a bitmap.
综上所述,本实施例提供的方法,提供了一种确定DCI是否是无数据调度的DCI的方法,进而终端可以根据该方法判断是否存在上述情况一中的第二指示域、上述情况三中的第一指示域和第二指示域,基于判断结果进行目标指示域的选择,保障了辅助载波的睡眠指示方法的准确性。In summary, the method provided in this embodiment provides a method for determining whether the DCI is a DCI without data scheduling, and then the terminal can determine whether there is the second indication field in the above case 1 and the above case 3 according to the method. In the first indication field and the second indication field in, the target indication field is selected based on the judgment result, which ensures the accuracy of the sleep indication method of the auxiliary carrier.

After determining the sleep state of the auxiliary carrier, if a certain auxiliary carrier is switched from a non-sleep state to a sleep state, the terminal activates the sleep state of the BWP corresponding to the auxiliary carrier; if a certain auxiliary carrier is switched from a sleep state to a non-sleep state , The terminal adjusts the BWP corresponding to the auxiliary carrier to a non-sleep state.
示例性的,结合参考图12,在DRX的激活期(Active Time)内,终端通过主载波上的一个DCI,动态的调整一个辅助载波上的睡眠状态。其中,该DCI配置有至少一个指示域,该DCI既可以调度主载波的数据,也可以不调度主载波的数据。Exemplarily, referring to FIG. 12, in the Active Time of DRX, the terminal dynamically adjusts the sleep state on a secondary carrier through a DCI on the primary carrier. Wherein, the DCI is configured with at least one indication field, and the DCI may schedule data of the primary carrier or not schedule data of the primary carrier.
若通过少一个指示域中的目标指示域,确定辅助载波转换为睡眠状态,则激活睡眠BWP,终端在睡眠BWP对应的时间段内,监控PDCCH;若通过少一个指示域中的目标指示域,确定辅助载波转换为非睡眠状态,则切换为非睡眠BWP,终端在非睡眠BWP对应的时间段内,不监控PDCCH。If it is determined that the secondary carrier is converted to the sleep state through one less target indicator field in the indicator field, the sleep BWP is activated, and the terminal monitors the PDCCH during the time period corresponding to the sleep BWP; if one less target indicator field in the indicator field is passed, It is determined that the auxiliary carrier is converted to the non-sleep state, and then it is switched to the non-sleep BWP, and the terminal does not monitor the PDCCH during the time period corresponding to the non-sleep BWP.
综上所述,本实施例提供的方法,终端通过激活辅助载波对应的BWP的睡眠状态,实现了辅助载波的睡眠状态的调整。In summary, in the method provided in this embodiment, the terminal realizes the adjustment of the sleep state of the auxiliary carrier by activating the sleep state of the BWP corresponding to the auxiliary carrier.
