Description
本发明实施例涉及通信技术领域,尤其涉及一种通信方法及设备。The embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication method and device.
搜索空间集合(search space set)定义为承载终端设备检测物理下行控制信道(Physical Downlink Control CHannel,PDCCH)的时间资源。搜索空间集合包含多个侦听时间,终端设备需要在搜索空间集合的所对应的侦听时间检测搜索空间集合传输的PDCCH,终端设备在搜索空间集合的侦听时间检测到网络设备发送给该终端设备的PDCCH的情况下,终端设备按照该终端设备的PDCCH上承载的下行控制信令(Downlink Control Information,DCI)的指示进行相应的接收或者发送,终端设备在搜索空间集合的侦听时间中未检测到网络设备发送给该终端设备的PDCCH的情况下,终端设备等待下一个搜索空间集合的侦听时间。现有技术所定义的侦听时间具有一定的周期性,而通信数据一般都是突发性的数据包,很多情况下,终端设备在搜索空间集合的侦听时间中检测不到发送给该终端设备的PDCCH,但终端设备检测搜索空间集合传输的PDCCH需要消耗大量的资源,以致增加了终端设备的功耗。为了降低终端设备的功耗,一种方式是增大终端设备检测搜索空间集合传输的PDCCH的侦听时间的周期。然而,由于终端设备的业务有突发性业务,也有周期性业务,而增大检测搜索空间集合传输的PDCCH的侦听时间的周期,会增加业务时延。The search space set (search space set) is defined as the time resource that carries the terminal device to detect the physical downlink control channel (Physical Downlink Control CHannel, PDCCH). The search space set contains multiple listening times. The terminal device needs to detect the PDCCH transmitted by the search space set at the corresponding listening time of the search space set. The terminal device detects the network device and sends it to the terminal during the listening time of the search space set. In the case of the PDCCH of the device, the terminal device performs corresponding reception or transmission according to the instructions of the Downlink Control Information (DCI) carried on the PDCCH of the terminal device. When the PDCCH sent by the network device to the terminal device is detected, the terminal device waits for the listening time of the next search space set. The listening time defined in the prior art has a certain periodicity, and the communication data is generally burst data packets. In many cases, the terminal device cannot detect and send to the terminal during the listening time of the search space set The PDCCH of the device, but the terminal device detecting the PDCCH transmitted by the search space set needs to consume a lot of resources, so that the power consumption of the terminal device is increased. In order to reduce the power consumption of the terminal device, one way is to increase the period in which the terminal device detects the listening time of the PDCCH transmitted by the search space set. However, since the services of the terminal device have burst services and periodic services, increasing the period of detecting the PDCCH listening time transmitted by the search space set transmission will increase the service delay.
发明内容Summary of the invention
本发明实施例提供了一种通信方法及设备,用于降低终端设备功耗的同时不造成业务时延的增加。Embodiments of the present invention provide a communication method and device for reducing power consumption of a terminal device without causing an increase in service delay.
第一方面提供一种通信方法,根据规则确定第一侦听时间,在第一侦听时间检测在第一搜索空间集合传输的PDCCH。可见,检测搜索空间集合传输的PDCCH的侦听时间不是固定不变的,而是可以根据规则进行确定的,因此,可以降低终端设备功耗的同时不造成业务时延的增加。A first aspect provides a communication method that determines a first listening time according to rules, and detects the PDCCH transmitted in the first search space set at the first listening time. It can be seen that the listening time for detecting the PDCCH transmitted by the search space set is not fixed, but can be determined according to rules. Therefore, the power consumption of the terminal device can be reduced without causing an increase in service delay.
在一个实施例中,可以在第二侦听时间检测在第二搜索空间集合传输的终端设备的PDCCH上承载的包括该终端设备检测搜索空间集合的时间信息的DCI,并根据时间信息确定第一侦听时间。可见,可以根据网络设备发送的时间信息确定检测搜索空间集合传输的PDCCH的侦听时间,因此,可以降低终端设备功耗的同时不造成业务时延的增加。In one embodiment, the DCI including the time information of the terminal device detection search space set carried on the PDCCH of the terminal device transmitted in the second search space set may be detected at the second listening time, and the first Listening time. It can be seen that the listening time for detecting the PDCCH transmitted by the search space set can be determined according to the time information sent by the network device. Therefore, the power consumption of the terminal device can be reduced without causing an increase in service delay.
在一个实施例中,时间信息可以为该终端设备检测第一搜索空间集合的时间,也可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的时间间隔,还可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的侦听时间数量,还可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的侦听周期数量。In one embodiment, the time information may be the time when the terminal device detects the first search space set, or the time interval between the time when the terminal device detects the first search space set and the second listening time, or The number of listening times between the time when the terminal device detects the first search space set and the second listening time, and the detection between the time when the terminal device detects the first search space set and the second listening time Number of listening cycles.
在一个实施例中,可以先统计第三搜索空间集合的侦听时间或者多个搜索空间集合(即,一个或多个搜索空间集合)的侦听时间检测到发送给终端设备的PDCCH的第一次数,或者统计第四搜索空间集合的侦听时间或者多个搜索空间集合(即,一个或多个搜索空间 集合)的侦听时间未检测到发送给该终端设备的PDCCH的第二次数,之后根据第一次数或第二次数调整该终端设备的侦听周期。可见,可以根据统计的在侦听时间检测到或未检测到发送给终端设备的PDCCH的次数动态的调整终端设备的侦听周期,因此,可以降低终端设备功耗的同时不造成业务时延的增加。侦听周期为检测搜索空间集合的周期。侦听周期大于或等于第一阈值且小于或等于第二阈值,即虽然侦听周期可以动态调整,但只能在一定的范围内进行调整,从而可以保证侦听周期不会太短,也不会太长。In one embodiment, the listening time of the third search space set or the listening time of multiple search space sets (ie, one or more search space sets) may be first counted to detect the first PDCCH sent to the terminal device The number of times, or counting the listening time of the fourth search space set or the second number of times the listening time of multiple search space sets (ie, one or more search space sets) does not detect the PDCCH sent to the terminal device, Then, the listening period of the terminal device is adjusted according to the first or second times. It can be seen that the listening period of the terminal device can be dynamically adjusted according to the statistical number of times the PDCCH sent to the terminal device is detected or not detected during the listening time, therefore, the power consumption of the terminal device can be reduced without causing service delay increase. The listening period is the period for detecting the set of search spaces. The listening period is greater than or equal to the first threshold and less than or equal to the second threshold, that is, although the listening period can be adjusted dynamically, it can only be adjusted within a certain range, so as to ensure that the listening period is not too short, nor It will be too long.
在一个实施例中,在第一次数大于或等于第三阈值的情况下,可以减小该终端设备的侦听周期,即在网络设备向终端设备发送的PDCCH较多的情况下,可以减小终端设备的侦听周期,以便终端设备可以不错过发送给该终端设备的PDCCH,从而可以不造成业务时延的增加。在第二次数大于或等于第四阈值的情况下,可以增大该终端设备的侦听周期,即在网络设备向终端设备发送的PDCCH较少的情况下,可以增大终端设备的侦听周期,以便可以降低终端设备的功耗。因此,可以根据在侦听时间检测到或未检测到终端设备的PDCCH的次数动态的调整侦听周期,从而可以降低终端设备功耗的同时不造成业务时延的增加。In one embodiment, in the case where the first number of times is greater than or equal to the third threshold, the listening period of the terminal device can be reduced, that is, when the network device sends more PDCCHs to the terminal device, it can be reduced The listening period of the small terminal device, so that the terminal device can not miss the PDCCH sent to the terminal device, so as not to cause an increase in service delay. When the second number of times is greater than or equal to the fourth threshold, the listening period of the terminal device can be increased, that is, when the network device sends less PDCCH to the terminal device, the listening period of the terminal device can be increased So that the power consumption of the terminal device can be reduced. Therefore, the listening period can be dynamically adjusted according to the number of times the PDCCH of the terminal device is detected or not detected during the listening time, so that the power consumption of the terminal device can be reduced without causing an increase in service delay.
在一个实施例中,可以接收来自网络设备的默认搜索空间集合配置,在第一时间检测默认搜索空间集合配置对应的第五搜索空间集合,终端设备只需要检测默认搜索空间集合,因此,可以减少终端设备的检测次数,从而可以降低终端设备的功耗。In one embodiment, the default search space set configuration from the network device can be received, and the fifth search space set corresponding to the default search space set configuration is detected at the first time, and the terminal device only needs to detect the default search space set, therefore, it can be reduced The number of detections of the terminal device, so that the power consumption of the terminal device can be reduced.
在一个实施例中,接收到来自网络设备的默认搜索空间集合配置之后,还可以接收来自网络设备的携带有触发指令的动态信令或媒体访问控制(Media Access Control,MAC)信令,并根据触发指令检测除第五搜索空间集合之外的搜索空间集合,以便终端设备可以根据网络设备的触发指令检测除默认搜索空间集合之外的搜索空间集合。In one embodiment, after receiving the default search space set configuration from the network device, it may also receive dynamic signaling or media access control (MAC) signaling from the network device that carries the trigger instruction, and according to The trigger instruction detects a search space set other than the fifth search space set, so that the terminal device can detect a search space set other than the default search space set according to the trigger instruction of the network device.
第二方面提供一种通信方法,根据规则确定第一侦听时间,在第一侦听时间,在第一搜索空间集合传输PDCCH。由于终端设备的侦听时间需要与网络设备确定的该终端设备的侦听时间保持一致,可见,终端设备检测搜索空间集合传输的PDCCH的侦听时间不是固定不变的,而是可以根据规则进行确定的,因此,可以降低终端设备功耗的同时不造成业务时延的增加。The second aspect provides a communication method, which determines the first listening time according to the rule, and transmits the PDCCH in the first search space set at the first listening time. Since the listening time of the terminal device needs to be consistent with the listening time of the terminal device determined by the network device, it can be seen that the listening time of the PDCCH detected by the terminal device to detect the search space set transmission is not fixed but can be performed according to rules Certainly, therefore, the power consumption of the terminal device can be reduced without causing an increase in service delay.
在一个实施例中,可以先确定终端设备检测搜索空间集合的时间信息,之后可以根据时间信息确定第一侦听时间,同时,也可以在第二侦听时间,在第二搜索空间集合向该终端设备传输该终端设备的PDCCH,该PDCCH上承载有包括时间信息的DCI,时间信息可以指示该终端设备根据时间信息确定第一侦听时间。可见,终端设备可以根据网络设备发送的时间信息确定检测搜索空间集合传输的PDCCH的侦听时间,因此,可以降低终端设备功耗的同时不造成业务时延的增加。In one embodiment, the time information of the search space set detected by the terminal device may be determined first, and then the first listening time may be determined according to the time information. At the same time, the second search time may be sent to the The terminal device transmits the PDCCH of the terminal device, and the PDCCH carries DCI including time information, and the time information may instruct the terminal device to determine the first listening time according to the time information. It can be seen that the terminal device can determine the listening time for detecting the PDCCH transmitted by the search space set according to the time information sent by the network device. Therefore, the power consumption of the terminal device can be reduced without causing an increase in service delay.
在一个实施例中,时间信息可以为该终端设备检测第一搜索空间集合的时间,也可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的时间间隔,还可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的侦听时间数量,还可以为该终端设备检测第一搜索空间集合的时间与第二侦听时间之间的侦听周期数量。In one embodiment, the time information may be the time when the terminal device detects the first search space set, or the time interval between the time when the terminal device detects the first search space set and the second listening time, or The number of listening times between the time when the terminal device detects the first search space set and the second listening time, and the detection between the time when the terminal device detects the first search space set and the second listening time Number of listening cycles.
在一个实施例中,可以先统计第三搜索空间集合的侦听时间或者多个搜索空间集合的 侦听时间向终端设备发送PDCCH的第一次数,或者统计第四搜索空间集合的侦听时间或者多个搜索空间集合的侦听时间未向该终端设备发送PDCCH的第二次数,之后根据第一次数或第二次数调整该终端设备的侦听周期。由于终端设备需要与网络设备中该终端设备的侦听时间保持一致,可见,可以根据统计的在侦听时间向或未向该终端设备发送的PDCCH的次数动态的调整该终端设备的侦听周期,因此,可以降低终端设备功耗的同时不造成业务时延的增加。此外,由于网络设备与终端设备中的侦听时间保持一致,网络设备可以在终端设备的侦听时间将终端设备的PDCCH传输给终端设备,以便终端设备可以检测到发送给自身的PDCCH,从而可以不造成业务时延的增加。侦听周期为检测搜索空间集合的周期。侦听周期大于或等于第一阈值且小于或等于第二阈值,即虽然侦听周期可以动态调整,但只能在一定的范围内进行调整,从而可以保证侦听周期不会太短,也不会太长。In one embodiment, the listening time of the third search space set or the listening times of multiple search space sets may be counted first to send the PDCCH the first time to the terminal device, or the listening time of the fourth search space set may be counted Or the listening times of multiple search space sets do not send the second number of PDCCHs to the terminal device, and then the listening period of the terminal device is adjusted according to the first number or the second number of times. Since the terminal device needs to be consistent with the listening time of the terminal device in the network device, it can be seen that the listening period of the terminal device can be dynamically adjusted according to the statistics of the number of PDCCHs sent to or not sent to the terminal device during the listening time Therefore, the power consumption of the terminal device can be reduced without increasing the service delay. In addition, since the listening time in the network device and the terminal device are consistent, the network device can transmit the PDCCH of the terminal device to the terminal device at the listening time of the terminal device, so that the terminal device can detect the PDCCH sent to itself, so that Does not cause an increase in business delay. The listening period is the period for detecting the set of search spaces. The listening period is greater than or equal to the first threshold and less than or equal to the second threshold, that is, although the listening period can be adjusted dynamically, it can only be adjusted within a certain range, so as to ensure that the listening period is not too short, nor It will be too long.
在一个实施例中,在第一次数大于或等于第三阈值的情况下,减小该终端设备的侦听周期,在第二次数大于或等于第四阈值的情况下,增大该终端设备的侦听周期。因此,可以根据在侦听时间向到或未向终端设备发送该终端设备的PDCCH的次数动态的增大或减小该终端设备的侦听周期,从而可以降低终端设备功耗的同时不造成业务时延的增加。In one embodiment, when the first number of times is greater than or equal to the third threshold, the listening period of the terminal device is reduced, and when the second number of times is greater than or equal to the fourth threshold, the terminal device is increased Listening cycle. Therefore, it is possible to dynamically increase or decrease the listening period of the terminal device according to the number of times the terminal device's PDCCH is sent to or not sent to the terminal device at the listening time, thereby reducing the power consumption of the terminal device without causing traffic Increase in latency.
在一个实施例中,可以向该终端设备发送默认搜索空间集合配置,默认搜索空间集合配置可以指示终端设备在第一时间检测默认搜索空间集合配置对应的第五搜索空间集合。默认搜索空间集合配置可以为默认搜索空间集合的标识、传输时间等信息。可见,网络设备可以指示终端设备只检测默认搜索空间集合,因此,可以减少终端设备的检测次数,从而可以降低终端设备的功耗In one embodiment, a default search space set configuration may be sent to the terminal device, and the default search space set configuration may instruct the terminal device to detect the fifth search space set corresponding to the default search space set configuration at the first time. The default search space set configuration may be information such as the identification and transmission time of the default search space set. It can be seen that the network device can instruct the terminal device to detect only the default search space set, therefore, the number of detections of the terminal device can be reduced, thereby reducing the power consumption of the terminal device
在一个实施例中,向该终端设备发送默认搜索空间集合配置之后,可以向该终端设备发送携带有触发指令的动态信令或MAC信令,触发指令可以指示终端设备检测除第五搜索空间集合之外的搜索空间集合,可见,网络设备在存在业务需求的情况下,可以通过指令的方式激活终端设备检测除默认搜索空间集合之外的搜索空间集合。In one embodiment, after sending the default search space set configuration to the terminal device, the terminal device may be sent dynamic signaling or MAC signaling carrying a trigger instruction, and the trigger instruction may instruct the terminal device to detect the fifth search space set In addition to the search space set, it can be seen that the network device can activate the terminal device to detect the search space set other than the default search space set by means of instructions when there is a service requirement.

Please refer to FIG. 1, which is a schematic diagram of a network architecture provided by an embodiment of the present invention. As shown in FIG. 1, the network architecture may include terminal device 1 and network device 2, and radio wave, visible light, laser, infrared light, photon, power line, coaxial cable, and copper strand may be used between terminal device 1 and network device 2. Line etc. to communicate. The terminal device 1 may also be a user equipment (User Equipment, UE) or a subscriber station (Subscriber Station, SS). The network device 2 may be a base station, a wireless access point, a transceiver station, a relay station, a cell, a transceiver point (Transmission and Receive Point, TRP), an evolved base station (Evolved Node, Base Station, eNB), a next-generation base station (next generation node) station, gNB), etc. The network device 2 is used to send the PDCCH to the terminal device 1, and indicates the information of the resource used to receive or transmit the signal through the PDCCH. The terminal device 1 is used to detect the PDCCH, and in the case of detecting its own PDCCH, obtain the information of the resource receiving or transmitting the signal from the signaling carried by the PDCCH, and receive or send the signal on the resource corresponding to the information, For example, receiving a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) or sending a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).
为了更好地理解本发明实施例提供的一种通信方法及设备,下面先对本发明实施例使用的一个应用场景进行描述。通常情况下,DCI承载在PDCCH上,网络设备会为终端设备配置检测PDCCH的时间资源和频率资源。控制资源集合(Control Resource Set,CORESET)定义承载PDCCH的频率资源和承载PDCCH的信令的时域长度,搜索空间集合为承载PDCCH的时间和频率资源集合,搜索空间集合的时域资源称为搜索空间集合的侦听时间(monitor occasion),由于搜索空间集合用于承载PDCCH,故也称为PDCCH的侦听时间,用于指示终端设备检测PDCCH的时间资源。请参阅图2,图2是本发明实施例提供的一种搜索空间集合侦听时间的示意图。如图2所示,网络设备配置给终端设备的搜索空间集合侦听时间包括侦听周期、侦听偏移量、侦听持续时间和侦听符号比特图。侦听周期,用于指示终端设备检测搜索空间集合的侦听时间的周期,通常以时隙为单位计量。侦听偏移量,用于指示在一个侦听周期内,终端设备检测搜索空间集合的第一个侦听时间距离该周期开始位置的偏移,以时隙为单位计量时,侦听偏移量,用于指示在一个侦听周期内,终端设备检测搜索空间集合的第一个侦听时间所在时隙距离该周期第一个时隙的时间偏移。侦听持续时间,用于指示在一个侦听周期内,终端设备检测搜索空间集合的侦听时间存在的连续时隙的数量。侦听符号比特图通过位图(bitmap)的形式指示搜索空间集合的侦听时间在一个时隙内的开始位置,如图2所示,1个时隙包括14个符号,每个符号可以对应一个比特,比特值为1对应的符号位置表示一个搜索空间集合的侦听时间的开始位置。其中,搜索空间集合中的一次侦听持续时间等于CORESET中所给出的时域长度。In order to better understand a communication method and device provided by the embodiments of the present invention, an application scenario used by the embodiments of the present invention will be described below. Generally, DCI is carried on the PDCCH, and the network device configures the terminal device with time and frequency resources for detecting the PDCCH. Control resource set (ControlReset, CORESET) defines the frequency resource carrying the PDCCH and the time domain length of the signaling carrying the PDCCH. The search space set is the time and frequency resource set carrying the PDCCH. The time domain resource of the search space set is called the search The monitoring time of the space set (monitor), because the search space set is used to carry the PDCCH, is also called the listening time of the PDCCH, and is used to instruct the terminal device to detect the time resource of the PDCCH. Please refer to FIG. 2, which is a schematic diagram of a search space set listening time according to an embodiment of the present invention. As shown in FIG. 2, the search space set listening time configured by the network device to the terminal device includes a listening period, a listening offset, a listening duration, and a listening symbol bitmap. The listening period is used to instruct the terminal device to detect the listening time of the search space set, which is usually measured in units of time slots. Listening offset, used to indicate that within a listening period, the terminal device detects the offset of the first listening time of the search space set from the beginning of the period. When measured in time slot units, the listening offset The quantity is used to indicate that within a listening period, the terminal device detects the time offset of the time slot where the first listening time of the search space set is located from the first time slot of the period. The listening duration is used to indicate the number of consecutive time slots in which the terminal device detects the listening time of the search space set during a listening period. The listening symbol bitmap indicates the starting position of the listening time of the search space set in a time slot in the form of a bitmap. As shown in FIG. 2, a time slot includes 14 symbols, and each symbol can correspond to One bit, the symbol position corresponding to the bit value 1 indicates the start position of the listening time of a search space set. Among them, the duration of one listening in the search space set is equal to the length of the time domain given in CORESET.
基于图1所示的网络架构,请参阅图3,图3是本发明实施例提供的一种通信方法的流程示意图。其中,该通信方法是从终端设备的角度来描述的。如图3所示,该通信方法可以包括以下步骤。Based on the network architecture shown in FIG. 1, please refer to FIG. 3, which is a schematic flowchart of a communication method according to an embodiment of the present invention. Among them, the communication method is described from the perspective of the terminal device. As shown in FIG. 3, the communication method may include the following steps.
301、根据规则确定第一侦听时间。301: Determine the first listening time according to the rules.
本实施例中,可以根据规则确定第一侦听时间,可以是先在第二侦听时间检测在第二搜索空间集合传输的终端设备的PDCCH上承载的包括该终端设备检测搜索空间集合的时间信息的DCI,之后根据该时间信息确定第一侦听时间。该时间信息可以是该终端设备下一次检测搜索空间集合的时间信息,也可以是下几次检测搜索空间集合的时间信息。在第一侦听时间与第二侦听时间之间可以有其它侦听时间,也可以没有其它侦听时间。在第一侦听时间与第二侦听时间之间有其它侦听时间的情况下,终端设备在这些侦听时间可以检测搜索空间集合,也可以不检测搜索空间集合。In this embodiment, the first listening time may be determined according to the rules, which may be that the time included in the PDCCH of the terminal device transmitted in the second search space set and including the terminal device detecting the search space set is first detected at the second listening time DCI of the information, and then determine the first listening time according to the time information. The time information may be time information for the next detection of the search space set by the terminal device, or may be time information for the next detection of the search space set. There may or may not be other listening time between the first listening time and the second listening time. When there are other listening times between the first listening time and the second listening time, the terminal device may detect the set of search spaces during these listening times, or may not detect the set of search spaces.
本实施例中,该时间信息可以为该终端设备检测搜索空间集合的时间,即网络设备可以将终端设备检测搜索空间集合的具体时间发送给终端设备。该时间信息也可以为该终端设备检测搜索空间集合的时间与第二侦听时间之间的时间间隔,即终端设备在接收到时间信息之后的多长时间后检测搜索空间集合。该时间信息还可以为该终端设备检测搜索空间集合的时间与第二侦听时间之间的侦听时间数量,即终端设备接收到时间信息之后间隔几 个侦听时间后检测搜索空间集合。该时间信息还可以为该终端设备检测搜索空间集合的时间与第二侦听时间之间的侦听周期数量,即终端设备接收到时间信息之后间隔几个侦听周期后检测搜索空间集合。其中一种具体的实施方法为,终端设备在搜索空间集合1(简称SS1,对应第二搜索空间)第N个侦听时间(对应第二侦听时间)中,检测到发送给终端设备的PDCCH,如果成功检测到发送给该终端设备的PDCCH,且在该PDCCH中包含的DCI中,包含终端设备下一次检测搜索空间集合1的时间信息,则终端设备根据该时间信息,确定下一次检测搜索空间集合1的侦听时间(对应第一侦听时间)。其中一种实施方法为,时间信息指示为下一次侦听搜索空间集合1的时间。如果第二侦听时间在M个时隙,时间信息为K,则终端设备下一次检测搜索空间集合1的侦听时间为(M+K)时隙。其中第二种实施方法为,时间信息指示下一次侦听搜索空间集合1与当前侦听时间之间的侦听时间次数,例如终端设备当前为搜索空间的第M个侦听时间,时间信息指示下一次侦听搜索空间集合1与当前侦听时间之间的侦听时间次数为K,则终端设备在当前侦听时间之后的第(M+K)次侦听时间检测搜索空间集合1。其中第三种实施方法为,时间信息指示为该终端设备检测搜索空间集合1的时间与当前侦听时间之间的侦听周期数量K,则终端设备在当前侦听时间后的第K个侦听周期检测搜索空间集合1。In this embodiment, the time information may be the time when the terminal device detects the search space set, that is, the network device may send the specific time when the terminal device detects the search space set to the terminal device. The time information may also be a time interval between the time when the terminal device detects the search space set and the second listening time, that is, how long after the terminal device receives the time information, the search space set is detected. The time information may also be the number of listening times between the time when the terminal device detects the search space set and the second listening time, that is, the terminal device detects the search space set after several listening times after receiving the time information. The time information may also be the number of listening cycles between the time when the terminal device detects the search space set and the second listening time, that is, the terminal device detects the search space set after a few listening cycles after receiving the time information. One specific implementation method is that the terminal device detects the PDCCH sent to the terminal device in the Nth listening time (corresponding to the second listening time) of the search space set 1 (referred to as SS1, corresponding to the second search space). If the PDCCH sent to the terminal device is successfully detected and the DCI contained in the PDCCH contains the time information of the next detection of the search space set 1 by the terminal device, the terminal device determines the next detection search based on the time information The listening time of space set 1 (corresponding to the first listening time). One of the implementation methods is that the time information indicates the next time to listen to the search space set 1. If the second listening time is in M time slots and the time information is K, then the next time that the terminal device detects the search space set 1 the listening time is (M + K) time slot. The second implementation method is that the time information indicates the number of listening times between the next listening search space set 1 and the current listening time, for example, the terminal device is currently the Mth listening time of the search space, and the time information indicates The number of listening time between the next listening search space set 1 and the current listening time is K, then the terminal device detects the search space set 1 at the (M + K) th listening time after the current listening time. The third implementation method is that the time information indicates the number K of the listening period between the time when the terminal device detects the search space set 1 and the current listening time, then the terminal device detects the Kth detection period after the current listening time Listening cycle detection search space set 1.
其中第二种具体的事实方法为,终端设备在搜索空间集合2(简称SS2,对应第二搜索空间)第N个侦听时间(对应第二侦听时间)中,检测发送给终端设备的PDCCH,如果成功检测到发送给终端设备的PDCCH,且在该PDCCH中包含的DCI中,包含该终端设备下一次检测搜索空间集合1的时间信息,则终端设备根据该时间信息,确定下一次检测搜索空间集合1的侦听时间(对应第一侦听时间)。其中一种实施方法为,时间信息指示下一次侦听搜索空间集合1的时间。如果第二侦听时间在第M个时隙,时间信息为K,则终端设备下一次检测搜索空间集合1的侦听时间为第(M+K)个时隙。其中第二种实施方法为,时间信息指示下一次侦听搜索空间集合1与当前侦听时间之间的侦听时间次数,例如终端设备当前为搜索空间的第M次侦听时间,时间信息指示下一次侦听搜索空间集合1与当前侦听时间之间的侦听时间次数为K,则终端设备在当前侦听时间之后的第(M+K)次侦听时间检测搜索空间集合1,这里的侦听时间的次数,可以是仅仅统计搜索空间集合1的侦听时间的次数,还可以统计搜索空间集合2的侦听时间的次数,还可以是统计搜索空间1的侦听时间和搜索空间集合2的侦听时间的次数,进一步的,如果终端设备还要检测搜索空间集合3,则还可以进一步包括搜索空间集合3的侦听时间的次数,等等。其中第三种实施方法为,时间信息指示为该终端设备检测搜索空间集合1的时间与当前侦听时间之间的侦听周期数量K,则终端设备在当前侦听时间后的第K个侦听周期检测搜索空间集合1,这里的侦听周期,可以是搜索空间集合1的侦听周期,也可以是搜索空间集合2的侦听周期,优选是搜索空间集合1的侦听周期。The second specific fact method is that the terminal device detects the PDCCH sent to the terminal device in the Nth listening time (corresponding to the second listening time) of the search space set 2 (referred to as SS2, corresponding to the second search space). If the PDCCH sent to the terminal device is successfully detected and the DCI included in the PDCCH contains the time information of the next detection of search space set 1 by the terminal device, the terminal device determines the next detection search based on the time information The listening time of space set 1 (corresponding to the first listening time). One of the implementation methods is that the time information indicates the next time when the search space set 1 is listened to. If the second listening time is in the Mth time slot and the time information is K, the terminal device next detects that the listening time for the search space set 1 is the (M + K) th time slot. The second implementation method is that the time information indicates the number of listening times between the next listening search space set 1 and the current listening time, for example, the terminal device is currently the Mth listening time of the search space, and the time information indicates The number of listening times between the next listening search space set 1 and the current listening time is K, then the terminal device detects the search space set 1 at the (M + K) th listening time after the current listening time, here The number of times of listening time may be only the number of times of listening time of search space set 1, the number of times of listening time of search space set 2 may also be counted, or the time of listening time and search space of search space 1 may be counted The number of times of listening time of set 2, further, if the terminal device also needs to detect the search space set 3, it may further include the number of times of listening time of the search space set 3, and so on. The third implementation method is that the time information indicates the number K of the listening period between the time when the terminal device detects the search space set 1 and the current listening time, then the terminal device detects the Kth detection period after the current listening time The listening period detects the search space set 1, and the listening period here may be the listening period of the search space set 1, or the listening period of the search space set 2, preferably the search period of the search space set 1.
本实施例中,根据规则确定第一侦听时间,也可以是先统计第三搜索空间集合的侦听时间或者多个搜索空间集合的侦听时间检测到发送给该终端设备的PDCCH的第一次数,或者统计第四搜索空间集合的侦听时间或者多个搜索空间集合的侦听时间未检测到发送给该终端设备的PDCCH的第二次数,之后根据第一次数或第二次数调整该终端设备的侦听周期。侦听周期为检测搜索空间集合的周期,侦听周期大于或等于第一阈值且小于或等于第 二阈值。可以在第一次数大于或等于第三阈值的情况下,减小该终端设备的侦听周期,在第二次数大于或等于第四阈值的情况下,增大该终端设备的侦听周期。可以通过计数器实现第一次数和/或第二次数的统计,可以通过两个计数器实现,即一个计数器统计第一次数,一个计数器统计第二次数,也可以通过两个计数器实现。其中,第三搜索空间集合的侦听时间与第四搜索空间集合的侦听时间可以连续的,也可以是非连续的,同理多个搜索空间集合以及多个搜索空间集合的侦听时间可以是连续的,也可以是非连续的。计数器每次增加的值相同,可以为1,也可以为其它值。这里的第三搜索空间集合和第四搜索空间集合,可以是同一个搜索空间集合,也可以是不同的搜索空间集合。In this embodiment, the first listening time is determined according to the rule, or it may be that the listening time of the third search space set or the listening time of multiple search space sets is first counted to detect the first PDCCH sent to the terminal device The number of times, or count the listening time of the fourth search space set or the listening times of multiple search space sets without detecting the second number of PDCCHs sent to the terminal device, and then adjust according to the first number or the second number The listening period of the terminal device. The listening period is the period for detecting the set of search spaces. The listening period is greater than or equal to the first threshold and less than or equal to the second threshold. When the first number of times is greater than or equal to the third threshold, the listening period of the terminal device may be reduced, and when the second number of times is greater than or equal to the fourth threshold, the listening period of the terminal device may be increased. The first count and / or the second count can be implemented by a counter, and can be implemented by two counters, that is, one counter counts the first count, one counter counts the second count, or can be implemented by two counters. The listening time of the third search space set and the listening time of the fourth search space set may be continuous or discontinuous. Similarly, the listening time of multiple search space sets and multiple search space sets may be Continuous or non-continuous. The value incremented by the counter every time is the same, which can be 1 or other values. Here, the third search space set and the fourth search space set may be the same search space set or different search space sets.
本实施例中,可以是在计数器的值每增加一次后就立即判断计数器统计的值是否满足调整侦听周期的条件,在判断出满足的情况下,调整侦听周期,同时将该计数器的值置零,在判断出不满足的情况下,将继续统计。在侦听时间和/或搜索空间集合为连续的情况下,可以通过一个计数器实现。在侦听时间和/或搜索空间集合为连续的情况下,也可以是在检测到发送给终端设备的PDCCH之后第一次未检测到发送给终端设备的PDCCH的情况下,判断第一次数是否大于或等于第三阈值,在判断出大于或等于第三阈值的情况下,减小侦听周期,同时将统计第一次数的计数器置零;在判断出小于第三阈值的情况下,将统计第一次数的计数器清零,同时统计第二次数的计数器增加一个值。同理也可以是在未检测到发送给终端设备的PDCCH之后第一次检测到发送给终端设备的PDCCH的情况下,判断第二次数是否大于或等于第四阈值,在判断出大于或等于第四阈值的情况下,增大侦听周期,同时将统计第二次数的计数器置零;在判断出小于第四阈值的情况下,将统计第二次数的计数器清零,同时统计第一次数的计数器增加一个值。减小或增大侦听周期时,每次减小或增大的值可以相同,也可以不同。在每次减小或增大的值不同的情况下,减小多少可以由第一次数决定,例如:减小后的侦听周期可以等于原侦听周期除以第一次数,同理增大多少可以由第二次数决定,例如:增大后的侦听周期可以等于原侦听周期乘以第二次数。其中,第一阈值可以为长非连续接收(Discontinuous Reception,DRX)周期,也可以为其它值,第二阈值可以为搜索空间集合的检测持续时间时隙,也可以为其它值。In this embodiment, it can be determined whether the value counted by the counter satisfies the condition for adjusting the listening period every time the value of the counter is increased, and when it is determined to be satisfied, the listening period is adjusted and the value of the counter is adjusted Set to zero, and continue to count when it is judged to be unsatisfactory. In the case where the set of listening time and / or search space is continuous, it can be implemented by a counter. In the case where the listening time and / or the search space set are continuous, it may be that the PDCCH sent to the terminal device is not detected for the first time after the PDCCH sent to the terminal device is detected. Whether it is greater than or equal to the third threshold, when it is determined that it is greater than or equal to the third threshold, the listening period is reduced, and the counter that counts the first number of times is set to zero; when it is determined that it is less than the third threshold, The counter counting the first count is cleared, and the counter counting the second count is increased by one value. In the same way, it is also possible to determine whether the second number of times is greater than or equal to the fourth threshold when the PDCCH sent to the terminal device is detected for the first time after the PDCCH sent to the terminal device is not detected. In the case of four thresholds, increase the listening period, and at the same time reset the counter that counts the second time to zero; when it is judged that it is less than the fourth threshold, clear the counter that counts the second time and count the first time Increments the counter by one. When decreasing or increasing the listening period, the value of each decrease or increase may be the same or different. When the value of each decrease or increase is different, the amount of decrease can be determined by the first number of times. For example, the reduced listening period can be equal to the original listening period divided by the first number of times. The increase can be determined by the second number of times. For example, the increased listening period can be equal to the original listening period multiplied by the second number of times. The first threshold may be a long discontinuous reception (DRX) period or other values, and the second threshold may be a detection duration time slot of the search space set or other values.
本实施例中,根据规则确定第一侦听时间,也可以是先统计第三搜索空间集合的侦听时间检测到发送给该终端设备的PDCCH的第一次数,之后根据第一次数调整该终端设备的侦听周期,其中一种具体的实施方法为,终端设备统计第三搜索空间集合的侦听时间连续地检测到发送给该终端设备的PDCCH的次数,之后根据该次数调整该第一搜索空间集合的侦听周期。例如,若当前搜索空间集合的侦听周期为M个时隙,且终端设备统计到第三搜索空间集合的连续L个侦听时间都检测到发送给该终端设备的PDCCH,或者终端设备统计到第三搜索空间集合的侦听时间(该侦听时间可以不连续)检测到发送给该终端设备的PDCCH的次数达到L,则减小搜索空间集合的侦听周期D,例如将D调整为max{1,ceill(D/2)}D/2,其中,ceill表示向上取整,max表示取两个数中的最大的数,此时,对应的侦听偏移可以保持不变,也可以对应的进行缩放。又例如,若终端设备统计到第四搜索空间集合的连续J个侦听时间都没有检测到发送给该终端设备的PDCCH,或者终端设备统计到第四搜索空间集合的侦听时间(该侦听时间可以不连续)没有检测到发送给该终端设备的PDCCH的次数达到J,则增大搜索空间集合的侦听周期D,例如将D调整为2*D,此时, 对应的侦听可以保持不变,也可以对应的进行缩放,优选对应的进行缩放,例如侦听偏移值为S,则调整后的侦听偏移值为floor(2*S),floor表示向下取整。In this embodiment, the first listening time is determined according to the rules, or it may be that the listening time of the third search space set is first counted to detect the first number of PDCCHs sent to the terminal device, and then adjusted according to the first number of times A specific implementation method of the listening period of the terminal device is that the terminal device counts the number of times the PDCCH of the third search space set continuously detects the PDCCH sent to the terminal device, and then adjusts the A listening period of the search space set. For example, if the listening period of the current search space set is M time slots, and the terminal device counts consecutive L listening times of the third search space set, the PDCCH sent to the terminal device is detected, or the terminal device counts The listening time of the third search space set (the listening time may not be continuous) detects that the number of PDCCHs sent to the terminal device reaches L, then reduces the listening period D of the search space set, for example, adjusting D to max {1, ceill (D / 2)} D / 2, where ceill means rounding up, and max means taking the largest of the two numbers. At this time, the corresponding listening offset may remain unchanged or it may Correspondingly zoom. For another example, if the terminal device does not detect the consecutive J listening times of the fourth search space set, the PDCCH sent to the terminal device is not detected, or the terminal device counts the listening time of the fourth search space set (the listening Time may be discontinuous) if the number of PDCCHs sent to the terminal device is not detected to reach J, increase the listening period D of the search space set, for example, adjust D to 2 * D. It can be scaled correspondingly, preferably correspondingly. For example, if the listening offset value is S, the adjusted listening offset value is floor (2 * S), and floor means rounding down.
本实施例中,根据规则确定第一侦听时间,也可以是先统计多个搜索空间集合的侦听时间检测到发送给该终端设备的PDCCH的第一次数,之后根据第一次数调整该终端设备的侦听周期,其中一种具体的实施方法为,终端设备统计多个搜索空间集合的侦听时间连续地检测到发送给该终端设备的PDCCH的次数,之后根据该次数调整该第一搜索空间集合的侦听周期。例如,若当前搜索空间集合的侦听周期为M个时隙,且终端设备统计到在多个搜索空间集合的连续L个侦听时间都检测到发送给该终端设备的PDCCH,或者终端设备统计到在多个搜索空间集合的侦听时间(该侦听时间可以不连续)检测到发送给该终端设备的PDCCH的次数达到L,则减小搜索空间集合的侦听周期D,例如将D调整为max{1,ceill(D/2)},此时,对应的侦听偏移可以保持不变,也可以对应的进行缩放。又例如,若终端设备统计到多个搜索空间集合的连续J个侦听时间都没有检测到发送给该终端设备的PDCCH,或者终端设备统计到在多个搜索空间集合的侦听时间(该侦听时间可以不连续)没有检测到发送给该终端设备的PDCCH的次数达到J,则增大搜索空间集合的侦听周期D,例如将D调整为2*D,此时,对应的侦听可以保持不变,也可以对应的进行缩放,优选对应的进行缩放,例如侦听偏移值为S,则调整后的侦听偏移值为floor(S*2)。In this embodiment, the first listening time is determined according to the rule, or it may be that the listening times of multiple search space sets are first counted to detect the first number of PDCCHs sent to the terminal device, and then adjusted according to the first number of times A specific implementation method of the listening period of the terminal device is that the terminal device counts the number of times of detection of multiple search space sets to continuously detect the number of PDCCHs sent to the terminal device, and then adjusts the A listening period of the search space set. For example, if the listening period of the current search space set is M time slots, and the terminal device counts consecutive L listening times in multiple search space sets, the PDCCH sent to the terminal device is detected, or the terminal device counts When the number of PDCCHs sent to the terminal device is detected to reach L during the listening time of multiple search space sets (the listening time may be discontinuous), the listening period D of the search space set is reduced, for example, adjusting D It is max {1, ceill (D / 2)}. At this time, the corresponding listening offset can be kept unchanged or can be scaled accordingly. For another example, if the terminal device does not detect the consecutive J listening times of multiple search space sets, the PDCCH sent to the terminal device is not detected, or the terminal device counts the listening times in multiple search space sets (the detection The listening time may be discontinuous) If the number of PDCCHs sent to the terminal device is not detected to reach J, increase the listening period D of the search space set, for example, adjust D to 2 * D. At this time, the corresponding listening can be If it remains unchanged, it can also be scaled correspondingly, preferably correspondingly. For example, if the listening offset value is S, the adjusted listening offset value is floor (S * 2).

The reduction of the listening period mentioned in the embodiment of the present invention may be a multiple reduction, for example, 2 times 3 times reduction, or a progressive reduction, for example, 1 reduction, 2 reduction, and so on.
本实施例中,根据规则确定第一侦听时间,也可以是先统计第三搜索空间集合的侦听时间或者多个搜索空间集合的侦听时间检测到发送给该终端设备的PDCCH的第一次数,具体的一种实施方法为,若终端有多个搜索空间集合,例如搜索空间集合1和搜索空间集合2,终端设备统计多个搜索空间集合的侦听时间检测到发送给该终端设备的PDCCH的第一次数,例如统计搜索空间集合1的侦听时间和搜索空间集合2的侦听时间检测到发送给该终端设备的PDCCH的第一次数。In this embodiment, the first listening time is determined according to the rules, or it may be that the listening time of the third search space set or the listening time of multiple search space sets is first counted to detect the first PDCCH sent to the terminal device. Times, a specific implementation method is that if the terminal has multiple search space sets, such as search space set 1 and search space set 2, the terminal device counts the listening time of the multiple search space sets and detects and sends it to the terminal device The first number of times of the PDCCH of the first time, for example, the statistics of the listening time of the search space set 1 and the listening time of the search space set 2 detect the first number of PDCCHs sent to the terminal device.

If the terminal device does not receive any scheduling information about itself within a certain period of time, the terminal device enters the sleep stage and stops monitoring the PDCCH channel. If in the continuous phase, the terminal device needs to start or restart the inactive timer (inactive timer) when the terminal device receives scheduling information related to itself on the PDCCH channel, the terminal device monitors the PDCCH during the period when the inactive timer has not expired The channel remains active. After that, if the inactive timer expires, it enters the sleep phase.
