Description

一种无线通信方法和装置Wireless communication method and device 技术领域Technical field
本申请涉及通信领域，尤其涉及一种无线通信方法和装置。The present application relates to the field of communications, and in particular, to a wireless communication method and device.
背景技术Background technique
在长期演进(long term evolution，LTE)通信***中，定义了非连续接收(discontinuous reception，DRX)功能，当终端设备处于无线资源控制(radio resource control，RRC)连接(connected)态时，DRX可以控制终端设备监测物理下行控制信道(physical downlink control channel，PDCCH)的行为，节省终端设备不必要的功耗。In a long term evolution (LTE) communication system, a discontinuous reception (DRX) function is defined. When a terminal device is in a radio resource control (RRC) connected state, DRX can Control the terminal device to monitor the behavior of the physical downlink control channel (PDCCH) to save unnecessary power consumption of the terminal device.
在载波聚合(carrier aggregation，CA)的场景下，终端设备可以将主小区(primary cell，PCell)和辅小区(secondary cell，SCell)等多个服务器小区对应的载波单元聚合起来发送数据，从而可以提高传输带宽。目前，DRX功能是针对终端设备的媒体访问控制(media access control，MAC)实体的，即一个MAC实体被配置一个DRX功能，因此终端设备根据相同的DRX参数在PCell和SCell上监测PDCCH，即当终端设备在PCell监测PDCCH时，同时也在SCell上监测PDCCH。In the case of carrier aggregation (CA), a terminal device can aggregate carrier units corresponding to multiple server cells such as a primary cell (PCell) and a secondary cell (SCell) to send data, so that it can send data. Increase transmission bandwidth. At present, the DRX function is targeted at the media access control (MAC) entity of the terminal device, that is, a MAC entity is configured with a DRX function, so the terminal device monitors the PDCCH on the PCell and SCell according to the same DRX parameter, that is, when When the PCell monitors the PDCCH, the terminal device also monitors the PDCCH on the SCell.
然而在实际调度中，PCell和SCell上的调度特征通常不相同。比如，在PCell上调度较多、较频繁，在SCell上调度较少、较稀疏。若对PCell和SCell进行PDCCH监测的时间一致，当终端设备在SCell监测PDCCH时，很少会收到PDCCH，从而造成终端设备的功耗浪费。However, in actual scheduling, the scheduling characteristics on PCell and SCell are usually different. For example, scheduling on PCell is more frequent and more frequent, and scheduling on SCell is less and sparse. If the PDCCH monitoring time for the PCell and the SCell are the same, when the terminal device monitors the PDCCH in the SCell, it rarely receives the PDCCH, which causes waste of power consumption of the terminal device.

新无线接入(new radio access technical，New RAT或NR)沿用了LTE的DRX机制。其中，New RAT或NR也可以称为第五代(the fifth generation，5G)移动通信***。终端设备(例如，用户设备(user equipment，UE))在RRC连接态时可以被配置DRX功能。DRX可以控制UE在一个DRX周期(DRX cycle)中的某些时间段内监测(监听)PDCCH，在其余时间段内不监测PDCCH。示例性的，DRX可以控制UE监测C-RNTI、配置调度无线网络临时标识(configured scheduling RNTI，CS-RNTI)、间断无线网络临时标识(interruption RNTI，INT-RNTI)、时隙格式指示无线网络临时标识(slot format indication RNTI，SFI-RNTI)、半静态信道状态信息无线网络临时标识(semi-persistent CSI RNTI，SP-CSI-RNTI)、传输功率控制无线网络临时标识(transmit power control RNTI，TPC-PUCCH-RNTI)、传输功率控制物理上行共享信道无线网络临时标识(transmit power control physical uplink shared channel RNTI，TPC-PUSCH-RNTI)或者传输功率控制探测参考信号无线网络临时标识(transmit power control sounding reference signal RNTI，TPC-SRS-RNTI)加扰的PDCCH。其中，RNTI是无线网络临时标识(radio network temporary identity)的简称。由于PDCCH可以用来承载DCI，因此RNTI加扰PDCCH也可以理解为RNTI加扰DCI。其中，加扰DCI的过程可以是DCI进行循环冗余校验(cyclic redundancy check，CRC)附着之后，使用无线网络临时标识对CRC校验位进行加扰；或者使用RNTI对DCI进行CRC附着之后的序列加扰。New radio access (new radio access technology, New RAT or NR) follows the DRX mechanism of LTE. Among them, New RAT or NR can also be called the fifth generation (5G) mobile communication system. A terminal device (for example, a user equipment (UE)) may be configured with a DRX function in an RRC connected state. The DRX can control the UE to monitor (listen to) the PDCCH in certain time periods in a DRX cycle, and not monitor the PDCCH in the remaining time periods. Exemplarily, the DRX may control the UE to monitor the C-RNTI, configure a scheduled wireless network temporary identity (configured RNTI, CS-RNTI), an intermittent wireless network temporary identity (interruption RNTI, INT-RNTI), and a time slot format to indicate that the wireless network is temporarily Identification (slot format indication RNTI, SFI-RNTI), semi-persistent channel state information wireless network temporary identification (semi-persistent CSI RNTI, SP-CSI-RNTI), transmission power control wireless network temporary identification (transmit power control RNTI, TPC- (PUCCH-RNTI), transmission power control physical uplink shared channel wireless network temporary identification (transmit power control physical uplink shared channel RNTI (TPC-PUSCH-RNTI)) or transmission power control detection reference signal wireless network temporary identification (transmit power control control sounding reference reference signal RNTI, TPC-SRS-RNTI) scrambled PDCCH. Among them, the RNTI is an abbreviation for radio network temporary identity. Since the PDCCH can be used to carry DCI, the RNTI scrambled PDCCH can also be understood as the RNTI scrambled DCI. The process of scrambling the DCI may be after the DCI attaches a cyclic redundancy check (CRC) and then uses a wireless network temporary identifier to scramble the CRC check bits; or it uses RNTI to attach the DCI to the CRC. Sequence scrambling.
如图1所示，一个DRX周期包括On Duration和Opportunity for DRX。其中，On Duration可以称为开启持续时间，Opportunity for DRX可以称为DRX机会。在On Duration起始时刻(或者DRX Cycle起始时刻)可以启动DRX开启持续时间定时器(drx-onDurationTimer，也可以称为onDurationTimer)。drx-onDurationTimer的时长为On Duration的时长，即drx-onDurationTimer的时长包括一个DRX cycle开始的一段持续时间。UE可以在On Duration期间内监测PDCCH，即UE可以在drx-onDurationTimer运行期间内监测PDCCH。当UE在drx-onDurationTimer运行期间内接收到调度上行(uplink，UL)或下行(downlink，DL)的新传输的PDCCH(即接收到一个新传的PDCCH)时，可以启动(或重启)非激活定时器(drx-InactivityTimer)。drx-InactivityTimer的时长包括UE接收到一个PDCCH后的一段持续时间，例如可以是该PDCCH所在子帧后的一段持续时间，也可以是该PDCCH所在的PDCCH时机后的一段持续时间。其中，该PDCCH可以用于指示UE一个新的UL或DL传输。PDCCH时机为用于终端设备监测PDCCH的一段时间(例如，一个或多个符号)，也可以称为PDCCH监测时机。UE可以在drx-InactivityTimer运行期间继 续监测PDCCH直到drx-InactivityTimer超时。As shown in Figure 1, a DRX cycle includes OnDuration and Opportunity for DRX. Among them, OnDuration can be called the opening duration, and Opportunity for DRX can be called the DRX opportunity. A DRX on-duration timer (drx-onDurationTimer, also called onDurationTimer) can be started at the start time of OnDuration (or the start time of DRX cycle). The duration of drx-onDurationTimer is the duration of OnDuration, that is, the duration of drx-onDurationTimer includes the duration of the beginning of a DRX cycle. The UE can monitor the PDCCH during the OnDuration period, that is, the UE can monitor the PDCCH during the drx-onDurationTimer operation period. When the UE receives a newly transmitted PDCCH (ie, receives a newly transmitted PDCCH) that schedules uplink (uplink, UL) or downlink (downlink, DL) during the drx-onDurationTimer operation period, it can start (or restart) the inactive Timer (drx-InactivityTimer). The duration of the drx-InactivityTimer includes a duration after the UE receives a PDCCH, for example, a duration after a subframe in which the PDCCH is located, or a duration after a PDCCH opportunity in which the PDCCH is located. The PDCCH may be used to indicate a new UL or DL transmission to the UE. The PDCCH timing is a period of time (eg, one or more symbols) used by the terminal device to monitor the PDCCH, and may also be referred to as a PDCCH monitoring timing. The UE may continue to monitor the PDCCH during drx-InactivityTimer operation until drx-InactivityTimer times out.
另外，当UE对数据的混合自动重传请求(hybrid automatic repeat request，HARQ)的PDCCH进行监听时，由于前一次传输和重传之间没有固定的时序关系，因此针对上行和下行HARQ进程(process)，分别定义了一个时间窗，允许UE从前一次上行或下行传输算起，并持续该时间窗后，才开始监听上行或下行的PDCCH。该时间窗可以通过定时器实现。每个上行HARQ进程和每个下行HARQ进程都可以对应一个定时器。例如，下行HARQ进程对应的定时器为HARQ RTT Timer或drx-HARQ-RTT-TimerDL，上行HARQ进程对应的定时器为UL HARQ RTT Timer或drx-HARQ-RTT-TimerUL。其中，RTT是往返时间(Round Trip Time)的简称。对于上行HARQ进程，当对应的定时器超时，对应的上行重传定时器(drx-RetransmissionTimerUL，也可以称为drx-ULRetransmissionTimer)启动。对于下行HARQ进程，当对应的定时器超时，对应的下行重传定时器(drx-RetransmissionTimerDL，也可以称为drx-RetransmissionTimer)启动。当drx-RetransmissionTimerUL或者drx-RetransmissionTimerDL运行时，UE可以监听PDCCH。其中，drx-RetransmissionTimerUL可以定义为：the maximum duration until a grant for UL retransmission is received(接收到一个上行重传授权的最大持续时间)。drx-RetransmissionTimerDL可以定义为：the maximum duration until a grant for DL retransmission is received(接收到一个下行重传的最大持续时间)。In addition, when the UE monitors the PDCCH of the hybrid automatic repeat request (HARQ) of the data, since there is no fixed timing relationship between the previous transmission and retransmission, the uplink and downlink HARQ processes are targeted. ) Respectively define a time window, allowing the UE to count from the previous uplink or downlink transmission and continue to monitor the uplink or downlink PDCCH only after the time window is continued. This time window can be implemented by a timer. Each uplink HARQ process and each downlink HARQ process can correspond to a timer. For example, the timer corresponding to the downlink HARQ process is HARQ RTT Timer or drx-HARQ-RTT-TimerDL, and the timer corresponding to the uplink HARQ process is UL HARQ RTT Timer or drx-HARQ-RTT-TimerUL. Among them, RTT is the abbreviation of Round Trip Time. For the uplink HARQ process, when the corresponding timer expires, the corresponding uplink retransmission timer (drx-RetransmissionTimerUL, also referred to as drx-ULRetransmissionTimer) starts. For the downlink HARQ process, when the corresponding timer expires, the corresponding downlink retransmission timer (drx-RetransmissionTimerDL, also called drx-RetransmissionTimer) starts. When drx-RetransmissionTimerUL or drx-RetransmissionTimerDL is running, the UE can monitor the PDCCH. Among them, drx-RetransmissionTimerUL can be defined as: the maximum duration of a grant for UL transmission (the maximum duration of receiving an uplink retransmission authorization). drx-RetransmissionTimerDL can be defined as: the maximum duration of the grant for DL retransmission is received (the maximum duration of receiving a downlink retransmission).
当DRX周期被配置时，UE可以在激活期(Active time)内监测PDCCH；否则，UE不需要监测PDCCH。其中，激活期包括：When the DRX cycle is configured, the UE can monitor the PDCCH during the active time; otherwise, the UE does not need to monitor the PDCCH. Among them, the activation period includes:
1)以下定时器中的至少一个正在运行的时间段：drx-onDurationTimer、drx-InactivityTimer、drx-RetransmissionTimerUL、drx-RetransmissionTimerDL或竞争解决定时器(ra-ContentionResolutionTimer或mac-ContentionResolutionTimer)。其中，竞争解决定时器可以用于确定随机接入过程中终端设备发送消息三后监测用于指示消息四的PDCCH的时间长度。1) At least one of the following timers is running: drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerUL, drx-RetransmissionTimerDL, or contention resolution timer (ra-ContentionResolutionTimer or mac-ContentionResolutionTimer). The contention resolution timer may be used to determine the length of time for monitoring the PDCCH indicating message four after the terminal device sends message three during the random access process.
2)调度请求(Scheduling Request，SR)被发送并且处于挂起(pending)。当一个SR被触发，该SR处于挂起直到它被取消。SR处于挂起的时间段即SR被发送的时刻到该SR被取消的时刻之间的时间段。2) A Scheduling Request (SR) is sent and is pending. When an SR is triggered, the SR is suspended until it is cancelled. The SR is in a suspended time period, that is, a time period between the time when the SR is transmitted and the time when the SR is cancelled.
3)终端设备成功接收一个RAR后还没有接收到一个指示新传的PDCCH。其中，该PDCCH由C-RNTI加扰，该RAR不是UE从基于竞争的随机接入前导选择的随机接入前导的RAR。3) After the terminal device successfully receives an RAR, it has not received a PDCCH indicating a new transmission. The PDCCH is scrambled by the C-RNTI, and the RAR is not the RAR of the random access preamble selected by the UE from the contention-based random access preamble.

其中，一个服务小区的PDCCH是指该PDCCH指示的传输是在该服务小区上的传输。例如，PCell的PDCCH是指该PDCCH指示的传输是在PCell上的传输。SCell的PDCCH是指该PDCCH指示的传输是在该SCell上的传输。例如，SCell1的PDCCH指该PDCCH指示的传输是在SCell1上的传输。The PDCCH of a serving cell means that the transmission indicated by the PDCCH is a transmission on the serving cell. For example, the PDCCH of the PCell means that the transmission indicated by the PDCCH is a transmission on the PCell. The PDCCH of the SCell means that the transmission indicated by the PDCCH is a transmission on the SCell. For example, the PDCCH of SCell1 means that the transmission indicated by the PDCCH is a transmission on SCell1.
举例来说，如图3a所示，假设终端设备被配置或被激活一个SCell。在第一定时器运行前，终端设备可以在PCell和SCell上都不监测PDCCH。当第一定时器开始运行后，终端设备进行第一处理，例如在PCell上监测PDCCH，并进行第二处理，例如在SCell上不监测PDCCH。For example, as shown in FIG. 3a, it is assumed that the terminal device is configured or an SCell is activated. Before the first timer runs, the terminal device may not monitor the PDCCH on both the PCell and the SCell. After the first timer starts running, the terminal device performs the first processing, for example, monitoring the PDCCH on the PCell, and performs the second processing, for example, not monitoring the PDCCH on the SCell.
在一种可能的设计中，第一条件还包括处于以下情况中的一个或多个：In a possible design, the first condition further includes one or more of the following conditions:
1)第二定时器未处于运行状态。可选的，可以是一个SCell对应的第二定时器未处于运行状态。或者，可以是多个SCell对应的同一个第二定时器未处于运行状态。其中，第二定时器用于确定终端设备在接收到PDCCH后监测PDCCH的时间长度，或者第二定时器用于确定终端设备在接收到指示新传的PDCCH后监测PDCCH的时间长度。举例来说，第二定时器可以为Drx-InactivityTimer。1) The second timer is not running. Optionally, the second timer corresponding to one SCell may not be in a running state. Alternatively, the same second timer corresponding to multiple SCells may not be in a running state. The second timer is used to determine the length of time that the terminal device monitors the PDCCH after receiving the PDCCH, or the second timer is used to determine the length of time that the terminal device monitors the PDCCH after receiving the newly transmitted PDCCH. For example, the second timer may be a Drx-InactivityTimer.
例如，若是一个SCell对应的第二定时器未处于运行状态，当第一定时器处于运行状态时，终端设备可以在PCell上监测PDCCH，并在该SCell上不监测PDCCH。若是多个SCell对应的同一个第二定时器未处于运行状态，当第一定时器处于运行状态时，终端设备可以在PCell上监测PDCCH，在该多个SCell上不监测PDCCH。再例如，若是一个SCell对应的第二定时器未处于运行状态，当第一定时器处于运行状态时，终端设备可以监测PCell的PDCCH，不监测该SCell的PDCCH。若是多个SCell对应的同一个第二定时器未处于运行状态，当第一定时器处于运行状态时，终端设备可以监测PCell的PDCCH，不监测该多个SCell的PDCCH。For example, if the second timer corresponding to an SCell is not in the running state, when the first timer is in the running state, the terminal device may monitor the PDCCH on the PCell and not monitor the PDCCH on the SCell. If the same second timer corresponding to multiple SCells is not in the running state, when the first timer is in the running state, the terminal device can monitor the PDCCH on the PCell, and does not monitor the PDCCH on the multiple SCells. For another example, if the second timer corresponding to an SCell is not in the running state, when the first timer is in the running state, the terminal device can monitor the PDCCH of the PCell, and does not monitor the PDCCH of the SCell. If the same second timer corresponding to multiple SCells is not in the running state, when the first timer is in the running state, the terminal device can monitor the PDCCH of the PCell and does not monitor the PDCCH of the multiple SCells.
另外，若第二定时器处于运行状态，无论第一定时器是否处于运行状态，终端设备在SCell上监测PDCCH直到第二定时器超时；或者，终端设备监测SCell的PDCCH直到第二定时器超时；或者终端设备在SCell上监测PDCCH并且监测SCell的PDCCH直到第二定时器超时。In addition, if the second timer is running, no matter whether the first timer is running, the terminal device monitors the PDCCH on the SCell until the second timer expires; or the terminal device monitors the PDCCH of the SCell until the second timer expires; Or the terminal device monitors the PDCCH on the SCell and monitors the PDCCH of the SCell until the second timer expires.
例如，如图3b所示，假设UE被配置或被激活一个SCell。在第一定时器(例如drx-onDurationTimer)运行前，UE在PCell和SCell上都不监测PDCCH。当drx-onDurationTimer开始运行后，UE开始在PCell上监测PDCCH，但在SCell上不监测PDCCH。当第二定时器(例如drx-InactivityTimer)开始运行后，UE开始在SCell上监测 PDCCH。UE可以在SCell上监测PDCCH直到drx-InactivityTimer超时。可选的，UE可以在PCell上监测PDCCH直到drx-InactivityTimer超时。For example, as shown in FIG. 3b, it is assumed that the UE is configured or activated with one SCell. Before the first timer (such as drx-onDurationTimer) runs, the UE does not monitor the PDCCH on both the PCell and the SCell. When drx-onDurationTimer starts to run, the UE starts monitoring the PDCCH on the PCell, but does not monitor the PDCCH on the SCell. After the second timer (for example, drx-InactivityTimer) starts to run, the UE starts monitoring the PDCCH on the SCell. The UE can monitor the PDCCH on the SCell until drx-InactivityTimer times out. Optionally, the UE may monitor the PDCCH on the PCell until drx-InactivityTimer times out.
在一种可能的设计中，若终端设备在PCell或SCell上监测到PDCCH，或者若终端设备在PCell或SCell上监测到指示新传的PDCCH，终端设备可以启动或重启第二定时器。可选的，若终端设备在PCell或一个SCell上监测到PDCCH，终端设备可以启动或重启该SCell对应的第二定时器。若终端设备在PCell或多个SCell中的任意一个SCell上监测到PDCCH，终端设备可以启动或重启该多个SCell对应的同一个第二定时器。In a possible design, if the terminal device monitors the PDCCH on the PCell or SCell, or if the terminal device monitors the newly transmitted PDCCH on the PCell or SCell, the terminal device can start or restart the second timer. Optionally, if the terminal device detects the PDCCH on the PCell or an SCell, the terminal device may start or restart a second timer corresponding to the SCell. If the terminal device monitors the PDCCH on the PCell or any one of the SCells, the terminal device can start or restart the same second timer corresponding to the multiple SCells.
举例来说，如图3c所示，在第一定时器运行期间，若终端设备在PCell上监测到PDCCH，可以启动第二定时器。在第二定时器运行期间，若终端设备在SCell上监测到PDCCH，可以重启第二定时器。For example, as shown in FIG. 3c, during the running of the first timer, if the terminal device monitors the PDCCH on the PCell, the second timer may be started. During the operation of the second timer, if the terminal device monitors the PDCCH on the SCell, the second timer may be restarted.
2)下行重传定时器未处于运行状态。例如，下行重传定时器可以为drx-RetransmissionTimerDL。可选的，该下行重传定时器可以是SCell上的DL HARQ进程对应的下行重传定时器。2) The downlink retransmission timer is not in the running state. For example, the downlink retransmission timer may be drx-RetransmissionTimerDL. Optionally, the downlink retransmission timer may be a downlink retransmission timer corresponding to a DL HARQ process on the SCell.
另外，若下行重传定时器处于运行状态，无论第一定时器是否处于运行状态，终端设备可以在SCell上监测PDCCH；或者，监测SCell的PDCCH；或者在SCell上监测PDCCH并且监测SCell的PDCCH。可选的，若下行重传定时器处于运行状态，终端设备可以在PCell上监测PDCCH；或者，监测PCell的PDCCH；或者在PCell上监测PDCCH并且监测PCell的PDCCH。In addition, if the downlink retransmission timer is in the running state, regardless of whether the first timer is in the running state, the terminal device can monitor the PDCCH on the SCell; or monitor the PDCCH on the SCell; or monitor the PDCCH on the SCell and monitor the PDCCH on the SCell.

For example, the uplink retransmission timer may be drx-RetransmissionTimerUL.

示例性的，在一种可能的情况中，若第一定时器处于运行状态，且第二定时器未处于运行状态，终端设备进行第一处理和第二处理。在又一种可能的情况中，若第一定时器处于运行状态，且第二定时器和下行重传定时器未处于运行状态，终端设备进行第一处理和第二处理。在再一种可能的情况中，若第一定时器处于运行状态，且第二定时器、下行重传定时器和上行重传定时器未处于运行状态，终端设备进行第一处理和第二处理。Exemplarily, in a possible case, if the first timer is in a running state and the second timer is not in a running state, the terminal device performs the first processing and the second processing.

现有技术中，终端设备根据相同的DRX参数在PCell和SCell上监测PDCCH。由于终端设备在SCell监测PDCCH很少会接收到PDCCH，从而造成终端设备功耗浪费。基于本申请实施例提供的方案，当第一定时器处于运行状态时，终端设备可以在SCell上不监测PDCCH和/或不监测SCell的PDCCH，从而降低了终端设备监测PDCCH的功耗。In the prior art, the terminal device monitors the PDCCH on the PCell and the SCell according to the same DRX parameter. Because the terminal device rarely receives the PDCCH while monitoring the PDCCH in the SCell, the terminal device consumes power. Based on the solution provided by the embodiment of the present application, when the first timer is in a running state, the terminal device may not monitor the PDCCH and / or the SCell PDCCH on the SCell, thereby reducing the power consumption of the terminal device monitoring the PDCCH.

If drx-InactivityTimer is started or restarted, start or restart the third timer. For example, as shown in FIG. 4c, it is assumed that the terminal device is configured or an SCell is activated. If the drx-InactivityTimer is started (for example, after the terminal device receives a PDCCH on the PCell, the drx-InactivityTimer starts to run), the third timer is started. The terminal device performs fourth processing during the operation of the second timer until the second timer expires; the terminal device performs third processing during the operation of the third timer until the third timer expires. After the third timer expires, if the drx-InactivityTimer restarts (for example, after the terminal device receives a PDCCH in the PCell during the drx-InactivityTimer operation, the drx-InactivityTimer restarts), the third timer starts. During the running of the third timer, if drx-InactivityTimer restarts, the third timer restarts. The terminal device performs third processing during the third timer operation until the third timer expires.
可选的，第三定时器的长度小于第二定时器的长度。定时器的长度也可以称为定时器的时长。其中，第三定时器的长度可以是网络设备配置的，例如可以是网络设备通过RRC信令配置的。这样一来，由于第三定时器的长度小于第二定时器的长度，终端设备在SCell上监测PDCCH的时长小于终端设备在PCell上监测PDCCH的时长，从而降低了终端设备监测SCell的PDCCH的功耗。Optionally, the length of the third timer is shorter than the length of the second timer. The length of the timer can also be called the duration of the timer. The length of the third timer may be configured by the network device, for example, may be configured by the network device through RRC signaling. In this way, because the length of the third timer is shorter than the length of the second timer, the duration that the terminal device monitors the PDCCH on the SCell is shorter than the duration that the terminal device monitors the PDCCH on the PCell, thereby reducing the power of the terminal device to monitor the PDCCH of the SCell. Consuming.
