具体实施方式Detailed ways
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。In order to understand the features and technical contents of the embodiments of the present application in more detail, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
在对本申请实施例进行说明之前，对相关内容进行简要说明。Before describing the embodiments of the present application, relevant contents are briefly described.
在新无线(New Radio，NR)***中，网络设备可以为终端设备配置非连续接收(Discontinuous Reception，DRX)功能，使终端设备在时域上的不连续检测(或监听)PDCCH，进而达到终端设备省电的目的。在没有数据传输的时候，可以通过终端设备停止接收PDCCH，即终端设备通过停止PDCCH盲检来降低功耗，从而提升终端设备的电池使用时间。In the New Radio (NR) system, the network equipment can configure the Discontinuous Reception (DRX) function for the terminal equipment, so that the terminal equipment can discontinuously detect (or monitor) the PDCCH in the time domain, and then reach the terminal equipment. The purpose of device power saving. When there is no data transmission, the terminal device can stop receiving the PDCCH, that is, the terminal device can reduce power consumption by stopping the blind detection of the PDCCH, thereby improving the battery life of the terminal device.
在现有的长期演进(Long Term Evolution，LTE)***中，可以为无线资源控制连接态(RRC_CONNECTED)的终端设备配置一个DRX周期(cycle)。DRX周期示意图，如图1所示，DRX cycle包括DRX激活期(Active Time)和DRX非激活期(Inactive Time；在DRX Active Time内，终端设备监听并接收PDCCH；在DRX Inactive Time(也可以称为休眠期)内，终端设备不接收PDCCH以减少功耗。寻呼消息的传输也适用于处于RRC空闲(idle)状态的DRX机制，此时DRX周期为寻呼消息的周期。In an existing Long Term Evolution (Long Term Evolution, LTE) system, a DRX cycle (cycle) may be configured for a terminal device in a radio resource control connected state (RRC_CONNECTED). A schematic diagram of the DRX cycle, as shown in Figure 1, the DRX cycle includes the DRX active period (Active Time) and the DRX inactive period (Inactive Time; during the DRX Active Time, the terminal device monitors and receives the PDCCH; During the sleep period), the terminal equipment does not receive the PDCCH to reduce power consumption. The transmission of the paging message is also applicable to the DRX mechanism in the RRC idle state, where the DRX cycle is the cycle of the paging message.
针对DRX机制，时间被划分成一个个连续的DRX cycle，每个DRX cycle的开始时刻为DRX ON状态,在DRX ON期间，终端设备会按照配置的监听(Monitoring Occasion，MO)检测PDCCH。当终端设备检测到PDCCH时，还启动和刷新对应的去激活定时器(Inactivity Timer)。如果DRX ON未结束或者Inactivity Timer未结束，则终端设备处于DRX Active Time。处于DRX Active Time的终端设备需要检测PDCCH。For the DRX mechanism, time is divided into successive DRX cycles, and the start time of each DRX cycle is the DRX ON state. During the DRX ON period, the terminal device will detect the PDCCH according to the configured Monitoring Occasion (MO). When the terminal device detects the PDCCH, it also starts and refreshes the corresponding inactivity timer (Inactivity Timer). If DRX ON does not end or Inactivity Timer does not end, the terminal device is in DRX Active Time. Terminal devices in DRX Active Time need to detect PDCCH.
NR***继承了LTE***中针对DRX的配置方式，终端设备在DRX active time期间监听所有配置的PDCCH搜索空间，并在DRX off期间停止监听所有配置的PDCCH搜索空间。在DRX active time期间，网络设备可以指示终端设备在一段时间内跳过或忽略PDCCH检测(PDCCH skipping)；其中，PDCCH skipping指示可以携带在DCI中，如利用DCI中的2比特信息指示PDCCH skipping的监听时机数量。终端设备跳过PDCCH检测的示意图，如图2所示，终端设备接收到PDCCH skipping指示后，在指示的监听时机内停止PDCCH监听(即PDCCH skipping)，并在指示的监听时机之外恢复PDCCH监听。The NR system inherits the configuration method for DRX in the LTE system. The terminal device monitors all the configured PDCCH search spaces during the DRX active time, and stops monitoring all the configured PDCCH search spaces during the DRX off period. During the DRX active time, the network device can instruct the terminal device to skip or ignore the PDCCH detection (PDCCH skipping) for a period of time; wherein, the PDCCH skipping indication can be carried in the DCI, such as using 2-bit information in the DCI to indicate the PDCCH skipping The number of listening times. The schematic diagram of the terminal equipment skipping PDCCH detection, as shown in Figure 2, after receiving the PDCCH skipping instruction, the terminal equipment stops PDCCH monitoring (ie PDCCH skipping) within the indicated listening timing, and resumes PDCCH monitoring outside the indicated monitoring timing .
申请人发现，终端设备在跳过PDCCH检测过程中，可能存在PDCCH丢失的问题，如图2所示，若网络设备在一个slot发送数据，但是终端设备在该slot可能未正确接收到数据。针对未正确接受的数据，网络设备需要执行数据重传；而PDCCH skipping过程中的数据重传必然会消耗网络资源，与为节能而实施的PDCCH skipping产生矛盾。本申请实施例提供的控制信道检测方法能够优化PDCCH skipping过程，在节省终端设备功耗的同时，使得终端设备能够执行有效的信道监听。The applicant found that when the terminal equipment skips the PDCCH detection process, there may be a problem of PDCCH loss. As shown in Figure 2, if the network equipment sends data in a slot, the terminal equipment may not receive data correctly in the slot. For incorrectly received data, network equipment needs to perform data retransmission; however, data retransmission during the PDCCH skipping process will inevitably consume network resources, which contradicts PDCCH skipping implemented for energy saving. The control channel detection method provided by the embodiment of the present application can optimize the PDCCH skipping process, and at the same time save the power consumption of the terminal device, enable the terminal device to perform effective channel monitoring.

在一些实施例中，终端设备在所述部分监听时机检测的控制信道的搜索空间类型，与承载所述第一DCI的控制信道的搜索空间类型相同。举例来说，若承载第一DCI的PDCCH的搜索空间类型为Type-0搜索空间，则终端设备在所述部分监听时机检测的控制信道的搜索空间类型也为Type-0搜索空间；若承载第一DCI的PDCCH的搜索空间类型为Type-1搜索空间，则终端设备在所述部分监听时机检测的控制信道的搜索空间类型也为Type-1搜索空间。In some embodiments, the search space type of the control channel detected by the terminal device at the partial listening opportunity is the same as the search space type of the control channel carrying the first DCI. For example, if the search space type of the PDCCH carrying the first DCI is Type-0 search space, the search space type of the control channel detected by the terminal device at the partial listening time is also Type-0 search space; The search space type of the PDCCH of a DCI is a Type-1 search space, and the search space type of the control channel detected by the terminal device at the partial listening timing is also a Type-1 search space.

If the type of the channel scheduled by the control channel carrying the first DCI is PDSCH, the type of the channel scheduled by the control channel detected by the terminal device at the partial listening opportunity is also PDSCH.
在一些实施例中，若网络设备需要重传数据包，则网络设备向终端设备发送第二DCI，所述第二DCI用于调度数据包重传。在具体实施时，若终端设备检测到所述第二DCI，则终端设备根据第二DCI能够确定重传数据包的时域位置，终端设备将在根据第二DCI所确定的时域位置接收重传的数据包。在该场景下，终端设备可以停止在所述部分监听时机检测所述控制信道。若第一DCI用于指示所述控制信道的检测参数，即控制信道的检测参数发生了变化，则终端设备除了可以停止在所述部分监听时机检测所述控制信道以外，还可以根据第一DCI指示的变化后检测参数检测控制信道。在具体实施时，若终端设备未检测到所述第二DCI，则终端设备在所述部分监听时机检测所述控制信道，以等待终端设备重传数据包。In some embodiments, if the network device needs to retransmit the data packet, the network device sends a second DCI to the terminal device, where the second DCI is used to schedule retransmission of the data packet. In specific implementation, if the terminal device detects the second DCI, the terminal device can determine the time domain position of the retransmitted data packet according to the second DCI, and the terminal device will receive the retransmission data packet at the time domain position determined according to the second DCI. transmitted data packets. In this scenario, the terminal device may stop detecting the control channel at the partial listening opportunity. If the first DCI is used to indicate the detection parameter of the control channel, that is, the detection parameter of the control channel has changed, the terminal device can stop detecting the control channel at the partial listening opportunity, and can also detect the control channel according to the first DCI. Indicated after the change of the detection parameter is detected in the control channel. In a specific implementation, if the terminal device does not detect the second DCI, the terminal device detects the control channel at the partial listening opportunity, so as to wait for the terminal device to retransmit the data packet.
本申请实施例提供的信道检测方法的示意图，如图8所示，网络设备在slot(x)传输完全部数据，但是，由于终端设备根据网络设备发送的DCI在slot(x)执行PDCCH skipping，则终端设备未成功接收slot(x)内传输的数据包；网络设备需重传该数据包。在该场景下，终端设备在PDCCH skipping的监听时机中的部分监听时间检测控制信道以接收重传数据包。若终端设备在所述部分监听时机中成功接收重传数据包，则终端设备可以停止在所述部分监听时机中检测控制信道，根据网络设备发送的DCI在slot(y)检测控制信道。The schematic diagram of the channel detection method provided by the embodiment of the present application, as shown in FIG. 8 , the network device transmits all data in slot(x), but since the terminal device performs PDCCH skipping in slot(x) according to the DCI sent by the network device, Then the terminal device fails to receive the data packet transmitted in slot(x); the network device needs to retransmit the data packet. In this scenario, the terminal device detects the control channel during part of the listening time in the listening opportunity of PDCCH skipping to receive the retransmitted data packet. If the terminal device successfully receives the retransmitted data packet in the partial listening opportunity, the terminal device may stop detecting the control channel in the partial listening opportunity, and detect the control channel at slot(y) according to the DCI sent by the network device.
本申请实施例提供的控制信道检测方法，将网络设备指示的PDCCH skipping的监听时机中的部分监听时机作为数据包重传的窗口，可以减少终端设备对重传的数据包的PDCCH检测；保证终端设备未成功接收网络设备发送PDCCH skipping指示时所调度的数据包的情况下，能够较快地完成未成功接收的数据包的重传。并且，由于数据包的重传窗口位于PDCCH skipping的监听时机内，能够避免在PDCCH skipping之后重传数据包带来的***时延。本申请实施例提供的控制信道检测方法对PDCCH的功能进行了扩展，使得PDCCH不仅具备调度PUSCH和指示PDCCH skipping的功能，还具备指示数据包重传的时间窗的功能；针对数据包重传，无需额外的物理层节能信号，不引入额外的信令，极大地节省了无线资源。由于终端设备在PDCCH skipping的监听时机中的部分监听时机与PDCCH中已经携带的时域参数k0、k1、k2有关，因此，本申请实施例中用于节能指示(在部分监听时机检测控制信道)的比特位在PDCCH携带的指示信息中所占的比重小，节省***资源。采用本申请实施例提供的控制信道检测方法，能够根据k0、k1、k2、网络设备指示的调整偏移值动态的支持终端设备节能，且终端设备节能的自适应时间尺度可以从数十微秒级降低至微秒级。In the control channel detection method provided by the embodiment of the present application, some of the listening timings of the PDCCH skipping indicated by the network device are used as the window for data packet retransmission, which can reduce the PDCCH detection of the retransmitted data packet by the terminal device; If the device fails to receive the data packet scheduled when the network device sends the PDCCH skipping indication, it can quickly complete the retransmission of the unsuccessfully received data packet. Moreover, since the retransmission window of the data packet is located within the listening opportunity of the PDCCH skipping, the system delay caused by the retransmission of the data packet after the PDCCH skipping can be avoided. The control channel detection method provided in the embodiment of the present application extends the function of the PDCCH, so that the PDCCH not only has the functions of scheduling PUSCH and indicating PDCCH skipping, but also has the function of indicating the time window for data packet retransmission; for data packet retransmission, There is no need for additional physical layer energy-saving signals, and no additional signaling is introduced, which greatly saves wireless resources. Since part of the listening timings of the terminal equipment in the listening timings of PDCCH skipping are related to the time domain parameters k0, k1, and k2 already carried in the PDCCH, the embodiments of the present application are used for energy saving indication (detecting the control channel at the partial listening timings) The proportion of the bits in the indication information carried by the PDCCH is small, which saves system resources. By using the control channel detection method provided by the embodiment of the present application, it is possible to dynamically support the energy saving of the terminal device according to the adjustment offset value indicated by k0, k1, k2 and the network device, and the adaptive time scale of the energy saving of the terminal device can be from tens of microseconds down to the microsecond level.
本申请实施例提供的控制信道检测方法的另一种可选处理流程，如图9所示，包括以下步骤：Another optional processing flow of the control channel detection method provided by the embodiment of the present application, as shown in FIG. 9 , includes the following steps:
步骤S301，网络设备向终端设备发送第一DCI，所述第一DCI用于所述终端设备确定跳过控制信道检测的监听时机，所述跳过控制信道检测的的部分监听时机用于所述终端设备检测控制信道。Step S301, the network device sends a first DCI to the terminal device, where the first DCI is used by the terminal device to determine the listening timing for skipping control channel detection, and the partial listening timing skipped control channel detection is used for the The terminal device detects the control channel.
在一些实施例中，所述控制信道可以是PDCCH，所述控制信道也可以是免调度的PDSCH。In some embodiments, the control channel may be a PDCCH, and the control channel may also be a scheduling-free PDSCH.
在一些实施例中，以控制信道是PDCCH为例，第一DCI中的X比特用于直接指示所述PDCCH skipping的监听时机，即终端设备在第一DCI指示的监听时机内不检测PDCCH。第一DCI也可以用于指示控制信道的检测参数，终端设备根据所述控制信道的检测参数能够确定所述PDCCH skipping的监听时机；其中，所述控制信道的检测参数可以包括下述中的至少一项：所述控制信道的检测周期、所述控制信道的搜索空间集合、所述控制信道承载的DCI的格式和所述控制信道的类型。这里，所述控制信道的检测周期可以是两次相邻的控制信道检测之间的时间间隔；所述控制信道承载的DCI的格式可以是format-1或format-0；所述控制信道的类型可以是终端设备专有的控制信道、或多个终端设备公共的控制信道。所述第一DCI所指示的控制信道的检测参数可以与终端设备上一次接收到的检测参数不同，即控制信道的检测参数发生了调整；在控制信道的检测参数发生调整的情况下，如控制信道的检测周期或控制信道的搜索空间集合发生 变化，则终端设备在执行PDCCH检测时，必然会在一些监听时机跳过PDCCH检测。In some embodiments, taking the control channel as the PDCCH as an example, the X bits in the first DCI are used to directly indicate the listening timing of the PDCCH skipping, that is, the terminal device does not detect the PDCCH within the listening timing indicated by the first DCI. The first DCI can also be used to indicate the detection parameter of the control channel, and the terminal device can determine the monitoring timing of the PDCCH skipping according to the detection parameter of the control channel; wherein, the detection parameter of the control channel can include at least one of the following: One item: the detection period of the control channel, the search space set of the control channel, the format of the DCI carried by the control channel, and the type of the control channel.

The first time domain offset is represented by k0, the second time domain offset is represented by k1, and the adjustment offset is represented by m, where m is a preset integer value, and the first offset is equal to k0+k1+m.

在一些实施例中，终端设备在所述部分监听时机检测的控制信道的搜索空间类型，与承载所述第一DCI的控制信道的搜索空间类型相同。举例来说，若承载第一DCI的PDCCH的搜索空间类型为Type-0搜索空间，则终端设备在所述部分监听时机检测的控制信道的搜索空间类型也为Type-0搜索空间；若承载第一DCI的PDCCH的搜索空间类型为Type-1搜索空间，则终端设备在所述部分监听时机检测的控制信道的搜索空间类型也为Type-1搜索空间。In some embodiments, the search space type of the control channel detected by the terminal device at the partial listening opportunity is the same as the search space type of the control channel carrying the first DCI.
