Description
本发明涉及通信领域,特别涉及一种指示信息的接收方法、发送方法及装置。The present invention relates to the field of communications, and in particular to a receiving method, sending method and device of indication information.
利用非授权频段进行通信时,为了保证信道利用的公平性、控制通信设备间的相互干扰,需要采用先听后说(Listen Before Talk,LBT)的机制,即设备在发送信号之前需要检测目标频段是否正在被其他设备用于发送信号,仅当目标频段的检测结果为空闲状态时,才能够利用该频段信道发送信号。When using unlicensed frequency bands for communication, in order to ensure the fairness of channel utilization and control mutual interference between communication devices, it is necessary to adopt the Listen Before Talk (LBT) mechanism, that is, the device needs to detect the target frequency band before sending signals Whether it is being used by other devices to send signals, only when the detection result of the target frequency band is idle, can the frequency band channel be used to send signals.
一个设备占用非授权频段发送信号的时间长度与其检测时间有关,在长期演进(Long Term Evolution,LTE)的授权辅助接入(Licensed Assisted Access,LAA)中,对于信道接入类型1,根据竞争窗(Contention Window,CW)长度的不同,定义了四种信道接入优先级,竞争窗长度越长则检测信道空闲状态的时间越长,那么设备能够占用信道时间则越长。例如,当优先级p=1时,竞争窗的可选数值为{3,7},最多能够占用信道2ms的时间;而当优先级p=3时,竞争窗的可选数值为{15,31,63},最多能够占用信道8ms或10ms的时间。The length of time that a device occupies an unlicensed frequency band to send signals is related to its detection time. In the Long Term Evolution (LTE) Licensed Assisted Access (LAA), for channel access type 1, according to the contention window The length of the (Contention Window, CW) defines four channel access priorities. The longer the contention window, the longer it takes to detect the idle state of the channel, and the longer the device can occupy the channel. For example, when priority p=1, the optional value of the contention window is {3,7}, which can occupy the channel for 2ms at most; and when priority p=3, the optional value of the contention window is {15, 31,63}, can occupy the channel for 8ms or 10ms at most.
另外,LTE LAA中还规定了允许占用了信道的发送设备在其信道占用时间内与其响应设备(即接收设备)共享信道占用时间,该响应设备在该发送设备的信道占用时间内发送信号时可以使用25us的不带竞争窗的信道接入类型2进行信道空闲检测。In addition, LTE LAA also stipulates that a sending device that occupies a channel can share channel occupancy time with its responding device (i.e. receiving device) during its channel occupancy time. The responding device can transmit a signal during the channel occupancy Use 25us channel access type 2 without contention window for channel idle detection.
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。It should be noted that the above introduction to the technical background is only set forth to facilitate a clear and complete description of the technical solutions of the present invention and to facilitate the understanding of those skilled in the art. It should not be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention.
发明内容Summary of the invention
网络设备可以通过格式1C的公共控制信息指示信道占用时间内本子帧及下一子帧下行符号数,以及上行子帧相对于本子帧的偏移和上行子帧个数。当用户设备(User Equipment,UE)被调度的上传输在该公共控制信息所指示的上行子帧内时,UE可以共享该网络设备的信道占用时间,仅采用25us的信道接入类型2即可接入信道。The network device can indicate the number of downlink symbols in the current subframe and the next subframe within the channel occupation time, as well as the offset of the uplink subframe relative to the current subframe and the number of uplink subframes through the common control information of the format 1C. When the user equipment (User Equipment, UE) is scheduled to transmit in the uplink subframe indicated by the common control information, the UE can share the channel occupation time of the network equipment, and only use 25us channel access type 2 Access channel.
另外,在新无线(new radio,NR)系统中,一个时隙格式可以包括上行符号、下行符号以及灵活符号。网络设备可以通过如下三个阶段的配置信息为UE配置时隙格式:首先,网络设备可以通过公共配置信息TDD-UL-DL-ConfigurationCommon为服务小区内的UE配置周期性的上行和/或下行符号格式;其次,网络设备还可以通过UE专用配置信息TDD-UL-DL-ConfigDedicated改写由TDD-UL-DL-ConfigurationCommon配置为灵活符号的符号;另外,如果网络设备为UE进一步配置了SlotFormatIndicator信息,网络设备还可以通过由SFI-RNTI加扰的公共动态信令DCI format 2-0进一步将灵活符号改写为上行或下行符号。In addition, in a new radio (NR) system, a slot format may include uplink symbols, downlink symbols, and flexible symbols. The network equipment can configure the time slot format for the UE through the following three-stage configuration information: First, the network equipment can configure periodic uplink and/or downlink symbols for the UE in the serving cell through the common configuration information TDD-UL-DL-ConfigurationCommon Secondly, the network equipment can also rewrite the symbols configured as flexible symbols by TDD-UL-DL-ConfigurationCommon through UE-specific configuration information TDD-UL-DL-ConfigDedicated; in addition, if the network equipment further configures the SlotFormatIndicator information for the UE, the network The device can further rewrite the flexible symbols into uplink or downlink symbols through public dynamic signaling DCI format 2-0 scrambled by SFI-RNTI.
发明人发现,在LTE LAA中,没有检测和接收指示信道占用时间以及该信道占用时间内的上行和/或下行符号结构的指示信息的有效机制,另外,关于是否改写上行和/或下行符号的格式,并没有有效的指示方法。The inventor found that in LTE LAA, there is no effective mechanism for detecting and receiving indication information indicating the channel occupation time and the uplink and/or downlink symbol structure within the channel occupation time. In addition, there is no effective mechanism for whether to rewrite the uplink and/or downlink symbols. Format, and there is no effective way to indicate.

实施例1Example 1
本发明实施例提供了一种指示信息的接收方法,该方法应用于用户设备侧。The embodiment of the present invention provides a method for receiving indication information, and the method is applied to the user equipment side.
图2是本发明实施例1的指示信息的接收方法的一示意图,如图2所示,该方法包括:Fig. 2 is a schematic diagram of a method for receiving indication information according to Embodiment 1 of the present invention. As shown in Fig. 2, the method includes:
步骤201:在第一时间资源和第二时间资源上,以不同的时间间隔检测网络设备发送的第一指示信息;和/或Step 201: On the first time resource and the second time resource, detect the first indication information sent by the network device at different time intervals; and/or
步骤202:仅在一个第一频域单元内接收该第一指示信息,Step 202: Only receive the first indication information in a first frequency domain unit,
该第二时间资源是该第一时间资源以外的时间资源。The second time resource is a time resource other than the first time resource.
例如,该第一指示信息包括指示该第一时间资源以及该第一时间资源包含的上行符号和/或下行符号的下行控制信息。For example, the first indication information includes downlink control information indicating the first time resource and uplink symbols and/or downlink symbols contained in the first time resource.
这样,通过在第一时间资源上和第一时间资源以外的第二时间资源上以不同的时间间隔来检测指示该第一时间资源以及该第一时间资源上的上行和/或下行符号的指示信息,和/或,通过仅在一个第一频域单元内接收该第一指示信息,能够提高检测和接收该指示信息的效率,并可以根据实际需要,灵活的确定检测和接收该指示信息的方式,另外,可以根据实际需要灵活的指示是否更新上行和/或下行符号的格式。In this way, by detecting the indication indicating the first time resource and the uplink and/or downlink symbols on the first time resource at different time intervals on the first time resource and the second time resource other than the first time resource Information, and/or, by receiving the first indication information in only one first frequency domain unit, the efficiency of detecting and receiving the indication information can be improved, and the detection and reception of the indication information can be flexibly determined according to actual needs. In addition, it is possible to flexibly indicate whether to update the format of the uplink and/or downlink symbols according to actual needs.
另外,该第一指示信息也可以是指示其他内容的下行控制信息。In addition, the first indication information may also be downlink control information indicating other content.
在本实施例中,并不限定步骤201和步骤202的时序关系。In this embodiment, the timing relationship between step 201 and step 202 is not limited.
在本实施例中,该第一时间资源是该第一指示信息所指示的资源,例如,该第一指示信息指示的第一时间资源是网络设备信道占有时间的资源。In this embodiment, the first time resource is the resource indicated by the first indication information, for example, the first time resource indicated by the first indication information is the resource for the time occupied by the network device channel.
在本实施例中,该第二时间资源是该第一时间资源以外的时间资源,例如,当该第一时间资源是网络设备信道占有时间的资源时,该第二时间资源是网络设备信道占有时间的资源以外的时间资源。In this embodiment, the second time resource is a time resource other than the first time resource. For example, when the first time resource is a resource for the channel occupancy of a network device, the second time resource is a channel occupancy of the network device. Time resources other than time resources.
在本实施例中,例如,该第一时间资源和该第二时间资源中的至少一个是非授权频段资源。In this embodiment, for example, at least one of the first time resource and the second time resource is an unlicensed frequency band resource.
在步骤201中,在第一时间资源和第二时间资源上,以不同的时间间隔检测网络设备发送的第一指示信息。In step 201, the first indication information sent by the network device is detected at different time intervals on the first time resource and the second time resource.
以下,对在第一时间资源和第二时间资源上如何以不同的时间间隔检测网络设备发送的第一指示信息进行示例性的说明。Hereinafter, how to detect the first indication information sent by the network device at different time intervals on the first time resource and the second time resource will be exemplarily described.
示例1、在该第二时间资源上,以第一时间间隔检测第一指示信息,在该第一时间资源上不检测或暂停检测该第一指示信息。Example 1. On the second time resource, the first indication information is detected at a first time interval, and the detection of the first indication information is not detected or suspended on the first time resource.
在本实施例中,例如,该第一时间间隔可以包括至少一个符号。In this embodiment, for example, the first time interval may include at least one symbol.
图3是本发明实施例1的检测第一指示信息的一示意图。如图3所示,在第一指示信息指示的第一时间资源以外的第二时间资源上,以第一时间间隔检测该第一指示信息,在该第一指示信息指示的第一时间资源上,不检测或暂停检测该第一指示信息。FIG. 3 is a schematic diagram of detecting first indication information in Embodiment 1 of the present invention. As shown in FIG. 3, on a second time resource other than the first time resource indicated by the first indication information, the first indication information is detected at a first time interval, and the first indication information is detected on the first time resource indicated by the first indication information. , Do not detect or suspend the detection of the first indication information.
在本实施例中,在第二时间资源上以第一时间间隔检测该第一指示信息时,可以周期性的或非周期性的在以第一时间间隔开的至少一个符号上检测该第一指示信息。In this embodiment, when the first indication information is detected at the first time interval on the second time resource, the first indication information may be detected periodically or aperiodically on at least one symbol separated by the first time interval. Instructions.
这样,由于UE接收到该第一指示信息后已经获得了该第一指示信息指示的第一时间资源,例如,网络设备信道占有时间的资源,因此在该第一时间资源上,不需要再检测该第一指示信息,从而能够减少UE功率消耗,另外,节省了信令开销,提高了资源利用率。In this way, since the UE has already obtained the first time resource indicated by the first indication information after receiving the first indication information, for example, the resource of the time occupied by the network device channel, there is no need to check on the first time resource. The first indication information can reduce UE power consumption, in addition, save signaling overhead, and improve resource utilization.
示例2、在该第二时间资源内的,第二时间间隔中的指定符号上检测第一指示信息,该第二时间资源包含至少一个第二时间间隔;在该第一时间资源内以第二时间间隔为周期的符号上检测第一指示信息。Example 2. In the second time resource, the first indication information is detected on the designated symbol in the second time interval, and the second time resource includes at least one second time interval; in the first time resource, the second The first indication information is detected on a symbol whose time interval is a period.
在本实施例中,该以第二时间间隔为周期的时间资源中的指定符号可以是:以一个第二时间间隔的起始符号为起点的、在至少一个第三时间间隔内以第一时间间隔为周期的符号;或者,一个第二时间间隔中的至少一个第三时间间隔内通过位图(bitmap)或索引值指示的符号,其中,该第一时间间隔≤该第三时间间隔≤该第二时间间隔。In this embodiment, the designated symbol in the time resource whose period is the second time interval may be: a start symbol of a second time interval as a starting point, and a first time interval in at least one third time interval. An interval is a symbol of a period; or, a symbol indicated by a bitmap or an index value in at least one third time interval in a second time interval, where the first time interval ≤ the third time interval ≤ the The second time interval.
例如,该第三时间间隔是时隙或子帧,该第二时间间隔包含至少一个第三时间间隔。For example, the third time interval is a time slot or a subframe, and the second time interval includes at least one third time interval.
图4是本发明实施例1的检测第一指示信息的另一示意图。如图4所示,在第二 时间资源内的,在第二时间间隔中的指定符号上检测第一指示信息,该指定符号是以一个第二时间间隔的起始符号为起点的、在至少一个第三时间间隔内以第一时间间隔为周期的多个符号,或者,一个第二时间间隔中的至少一个第三时间间隔内通过位图(bitmap)或索引值指示的符号;在第一时间资源内以第二时间间隔为周期的符号上检测第一指示信息。该第一指示信息例如是包括指示该第一时间资源以及该第一时间资源包含的上行符号和/或下行符号的下行控制信息。FIG. 4 is another schematic diagram of detecting first indication information in Embodiment 1 of the present invention. As shown in Fig. 4, in the second time resource, the first indication information is detected on the designated symbol in the second time interval. The designated symbol starts from the start symbol of a second time interval and is at least A plurality of symbols in a third time interval with the first time interval as the period, or at least one symbol indicated by a bitmap or index value in at least one third time interval in a second time interval; The first indication information is detected on the symbols with the second time interval as the period in the time resource. The first indication information includes, for example, downlink control information indicating the first time resource and uplink symbols and/or downlink symbols included in the first time resource.
这样,UE以较密周期检测第一指示信息,减小了漏检测的概率。而在检测到第一指示信息后以较稀疏的周期检测第一指示信息,既可以减小功率消耗,又可以获得更新的第一指示信息。In this way, the UE detects the first indication information in a denser period, which reduces the probability of missed detection. After the first indication information is detected, the first indication information is detected in a sparse cycle, which can reduce power consumption and obtain updated first indication information.
另外,该第一指示信息例如是调度下行数据的下行控制信息。在第二时间资源中的第二时间间隔中的指定符号上检测该第一指示信息;在接收到一个指示第一时间资源的指示信息后,在第一时间资源内以第二时间间隔为周期检测该第一指示信息。In addition, the first indication information is, for example, downlink control information for scheduling downlink data. Detect the first indication information on the designated symbol in the second time interval in the second time resource; after receiving an indication information indicating the first time resource, use the second time interval as a period in the first time resource The first indication information is detected.
示例3、在该第二时间资源内的第二时间间隔中的第一指定符号上检测第一指示信息,在一个该第一时间资源的第一个第三时间间隔中的第二指定符号上检测第一指示信息。Example 3: The first indication information is detected on the first designated symbol in the second time interval of the second time resource, and the first indication information is detected on the second designated symbol in the first third time interval of the first time resource Detect the first indication information.
在本实施例中,该第一指定符号和示例2中的相同,例如是以一个第二时间间隔的起始符号为起点的、在至少一个第三时间间隔内以第一时间间隔为周期的符号;或者,一个第二时间间隔中的至少一个第三时间间隔内通过位图(bitmap)或索引值指示的符号,其中,该第一时间间隔≤该第三时间间隔≤该第二时间间隔。In this embodiment, the first designated symbol is the same as that in Example 2, for example, starting from the start symbol of a second time interval, and taking the first time interval as the period in at least one third time interval. Symbol; or, a symbol indicated by a bitmap or index value in at least one third time interval in a second time interval, wherein the first time interval ≤ the third time interval ≤ the second time interval .
在本实施例中,该第二指定符号和示例2中的类似,例如是以该第一时间资源的第一个第三时间间隔的起始符号为起点的、在该第三时间间隔内以第一时间间隔为周期的符号;或者,在该第一时间资源的第一个第三时间间隔内通过位图(bitmap)或索引值指示的符号,其中,该第一时间间隔≤该第三时间间隔。In this embodiment, the second designated symbol is similar to that in Example 2. For example, the start symbol of the first third time interval of the first time resource is taken as the starting point, and within the third time interval, The first time interval is a symbol of a period; or, the symbol indicated by a bitmap or an index value in the first third time interval of the first time resource, wherein the first time interval ≤ the third time interval time interval.
例如,该第三时间间隔是时隙或子帧,该第二时间间隔包含至少一个第三时间间隔。For example, the third time interval is a time slot or a subframe, and the second time interval includes at least one third time interval.
图5是本发明实施例1的检测第一指示信息的又一示意图。如图5所示,在第二时间资源内的,在以一个第二时间间隔的起始符号为起点的、在一个第三时间间隔内以第一时间间隔为周期的符号上检测第一指示信息;在第一时间资源内,在以该第一时间资源的第一个第三时间间隔的起始符号为起点的、在该第三时间间隔内以第一时 间间隔为周期的符号上检测第一指示信息。FIG. 5 is another schematic diagram of detecting first indication information in Embodiment 1 of the present invention. As shown in Figure 5, in the second time resource, the first indication is detected on a symbol starting from a start symbol of a second time interval and a period of the first time interval in a third time interval. Information; in the first time resource, detecting on symbols starting from the start symbol of the first third time interval of the first time resource and taking the first time interval as the period in the third time interval The first instruction information.
这样,例如,UE在第一时间资源的第一个时隙内多次接收第一指示信息,且指示内容相同,均指示接收到该第一指示信息的时隙开始的第一时间资源内的上行和/或下行符号格式,节省了高层配置信令开销。并且,由于多次接收的第一指示信息指示的内容相同,UE可以将多次接收到的第一指示信息进行软合并,提高了第一指示信息的准确性。In this way, for example, the UE receives the first indication information multiple times in the first time slot of the first time resource, and the indication content is the same, and all indicate the information in the first time resource starting from the time slot where the first indication information is received. The uplink and/or downlink symbol format saves high-level configuration signaling overhead. In addition, since the contents indicated by the first indication information received multiple times are the same, the UE can soft-combine the first indication information received multiple times, which improves the accuracy of the first indication information.
在本实施例中,该第一时间间隔、该第二时间间隔、该指定符号以及该第三时间间隔中的至少一个可以由网络设备通过无线资源控制消息或MAC CE信令通知。In this embodiment, at least one of the first time interval, the second time interval, the designated symbol, and the third time interval may be notified by the network device through a radio resource control message or MAC CE signaling.
在本实施例中,对于被网络设备指示为上行符号的符号,不在该符号上检测该第一指示信息。这样,可以提高检测的效率,减少UE功率消耗。In this embodiment, for a symbol indicated as an uplink symbol by the network device, the first indication information is not detected on the symbol. In this way, the detection efficiency can be improved and the UE power consumption can be reduced.
以上,对步骤201中的时域上的检测方式进行了示例性的说明。Above, the detection method in the time domain in step 201 has been exemplified.
在步骤202中,仅在一个第一频域单元内接收该第一指示信息,即,在频域上限定了接收第一指示信息的方式。In step 202, the first indication information is received only in one first frequency domain unit, that is, the manner of receiving the first indication information is defined in the frequency domain.

以下,对该一个第一频域单元通过无线资源控制消息进行通知进行示例性的说明。Hereinafter, the notification of the one first frequency domain unit through the radio resource control message will be exemplified.
例如,该无线资源控制消息指示该一个第一频域单元的标识,或者,该无线资源控制消息指示第二频域单元中的各个第一频域单元是否为该一个第一频域单元。For example, the radio resource control message indicates the identity of the one first frequency domain unit, or the radio resource control message indicates whether each first frequency domain unit in the second frequency domain unit is the one first frequency domain unit.
在本实施例中,该第二频域单元是传输带宽资源(Band Width Part,BWP),其例如是非授权频段资源;该第一频域单元是信道空闲检测(例如,CCA或LBT)的频域检测单位,例如,信道空闲检测子带宽。In this embodiment, the second frequency domain unit is a transmission bandwidth resource (Band Width Part, BWP), which is, for example, an unlicensed frequency band resource; the first frequency domain unit is a frequency for channel idle detection (for example, CCA or LBT).

For example, the configuration information is Mainsubband information, and the sub-bandwidth represented by the sub-bandwidth identifier carried by the information is the main sub-bandwidth. . In addition, the transmission bandwidth resource configuration information may also include configuration information of the sub-bandwidth included in the transmission bandwidth resource.
再例如,主要子带宽的配置信息可以包括在子带宽配置信息中,在配置该子带宽时指示该子带宽是否为主要子带宽。For another example, the configuration information of the main sub-bandwidth may be included in the sub-bandwidth configuration information, and when the sub-bandwidth is configured, it is indicated whether the sub-bandwidth is the main sub-bandwidth.
再例如,也可以是,在网络设备发送给UE的下行专用传输带宽资源的配置信息中包含主要子带宽的配置信息。For another example, it may also be that the configuration information of the downlink dedicated transmission bandwidth resource sent by the network device to the UE includes the configuration information of the main sub-bandwidth.

又例如,该第一指示信息的控制资源集合配置信息中所配置的控制资源集合的频域资源被配置在第二频域单元的一个第一频域单元内,并且,UE在该一个第一频域单元的该控制资源集合的频域资源内接收该第一指示信息。For another example, the frequency domain resources of the control resource set configured in the control resource set configuration information of the first indication information are configured in a first frequency domain unit of the second frequency domain unit, and the UE is in the first frequency domain unit. The first indication information is received in the frequency domain resource of the control resource set of the frequency domain unit.
以下,对该一个第一频域单元通过无线资源控制消息和MAC CE信令进行通知进行示例性的说明。Hereinafter, the notification of the one first frequency domain unit through the radio resource control message and MAC CE signaling will be exemplified.
例如,该无线资源控制消息配置具有至少一个第一频域单元的第二频域单元,该MAC CE信令激活该至少一个第一频域单元中的一个第一频域单元作为该一个第一频域单元。For example, the radio resource control message configures a second frequency domain unit with at least one first frequency domain unit, and the MAC CE signaling activates a first frequency domain unit of the at least one first frequency domain unit as the first frequency domain unit.

另外,在该MAC CE信令的该激活生效之前,可以在预定义的一个第一频域单元上接收该第一指示信息。In addition, before the activation of the MAC CE signaling takes effect, the first indication information may be received on a predefined first frequency domain unit.
例如,该预定义的第一频域单元可以是预定义的一个索引值的第一频域单元,例如,具有最小索引值或最大索引值的第一频域单元。For example, the predefined first frequency domain unit may be a first frequency domain unit with a predefined index value, for example, the first frequency domain unit with the smallest index value or the largest index value.
以上,对在步骤202中限定的仅在一个第一频域单元上接收第一指示信息的方式进行了示例性的说明。Above, the manner of receiving the first indication information on only one first frequency domain unit defined in step 202 has been exemplified.

在本实施例中,该用户设备从网络设备接收无线资源控制消息,该无线资源控制配置消息包含至少一个第四时间间隔包含的上行和/或下行符号的配置信息、至少一个第四时间间隔的级联以及该级联的标识的配置信息。In this embodiment, the user equipment receives a radio resource control message from the network device, and the radio resource control configuration message includes configuration information of uplink and/or downlink symbols included in at least one fourth time interval, and at least one fourth time interval The configuration information of the cascade and the identifier of the cascade.
在本实施例中,该第四时间间隔可以是以下的至少一个:整数个符号、时隙、子帧以及整数倍个毫秒的时间间隔。In this embodiment, the fourth time interval may be at least one of the following: an integer number of symbols, a time slot, a subframe, and a time interval of an integer multiple of milliseconds.
图6是本发明实施例1的无线资源控制配置消息的内容的一示意图。如图6所示,该无线资源控制消息包含标识分别为0~3的4个第四时间间隔的级联,并指示了每个第四时间间隔的上行和/或下行符号。例如,每个第四时间间隔包含14个符号,对于标识为2的级联,其包含4个第四时间间隔,其中,第1个第四时间间隔中均为下行(DL)符号,第2个第四时间间隔中前4个符号为下行符号,后10个符号为上行(UL)符号,第3个第四时间间隔中均为上行符号,第4个第四时间间隔中均为下行符号。FIG. 6 is a schematic diagram of the content of a radio resource control configuration message according to Embodiment 1 of the present invention. As shown in FIG. 6, the radio resource control message includes the concatenation of 4 fourth time intervals with identifiers 0 to 3, and indicates the uplink and/or downlink symbols of each fourth time interval. For example, each fourth time interval contains 14 symbols. For the concatenation identified as 2, it contains 4 fourth time intervals. Among them, the first and fourth time intervals are all downlink (DL) symbols, and the second The first 4 symbols in the fourth time interval are downlink symbols, the last 10 symbols are uplink (UL) symbols, the third and fourth time intervals are all uplink symbols, and the fourth and fourth time intervals are all downlink symbols. .
在本实施例中,该第一指示信息可以包含第一指示域,该第一指示域指示该网络设备通过无线资源控制消息为该用户设备配置的一个第四时间间隔的级联的标识,该用户设备通过该第一指示域确定第三时间资源以及第三时间资源包含的上行和/或下行符号。In this embodiment, the first indication information may include a first indication field, the first indication field indicating that the network device configures a fourth time interval cascade identifier for the user equipment through a radio resource control message, the The user equipment determines the third time resource and the uplink and/or downlink symbols contained in the third time resource through the first indication field.
在本实施例中,该第三时间资源可以是第一时间资源,例如,网络设备信道占用时间的资源,另外,该第三时间资源也可以包含第一时间资源,或者,与第一时间资源部分相同。In this embodiment, the third time resource may be a first time resource, for example, a resource occupied by a channel of a network device. In addition, the third time resource may also include the first time resource, or be combined with the first time resource. The parts are the same.
例如,该第三时间资源由整数个连续的第四时间间隔组成,该第三时间资源包含的第四时间间隔的个数通过该第一指示域指示的该标识对应的第四时间间隔的级联所包含的第四时间间隔的个数确定,该第三时间资源包含的上行和/或下行符号是该第一指示域指示的该标识对应的第四时间间隔的级联所表示的上行和/或下行符号。For example, the third time resource is composed of an integer number of consecutive fourth time intervals, and the number of fourth time intervals contained in the third time resource is the level of the fourth time interval corresponding to the identifier indicated by the first indicator field. The number of the fourth time interval included in the association is determined, and the uplink and/or downlink symbols included in the third time resource are the uplink and/or downlink symbols indicated by the cascade of the fourth time interval corresponding to the identifier indicated by the first indicator field. / Or downlink symbol.
图7是本发明实施例1的第一指示信息指示的指示内容的一示意图。如图7所示, 第一指示域指示的标识信息为2,参见图6和图7,标识为2的级联中包含了4个第四时间间隔,则网络设备通过该第一指示信息指示了从接收到该第一指示信息的第四时间间隔为起始的4个第四时间间隔的上行和/或下行符号的结构。所指示的级联中的第1个第四时间间隔的被配置为全下行符号,则接收到该第一指示信息的第四时间间隔中包含的14个符号均为下行符号;所指示的标识为2的级联中的第2个第四时间间隔被配置为前4个符号为下行符号,其余10个符号为上行符号,则表示接收到该第一指示信息的第四时间间隔的下一个第四时间间隔包括4个下行符号以及10个上行符号,后两个第四时间间隔同理。FIG. 7 is a schematic diagram of the instruction content indicated by the first instruction information in Embodiment 1 of the present invention. As shown in FIG. 7, the identification information indicated by the first indication field is 2. Referring to FIGS. 6 and 7, the cascade with the identification 2 includes 4 fourth time intervals, and the network device indicates by the first indication information The structure of the uplink and/or downlink symbols of 4 fourth time intervals starting from the fourth time interval in which the first indication information is received is presented. If the first fourth time interval in the indicated concatenation is configured as a full downlink symbol, the 14 symbols included in the fourth time interval in which the first indication information is received are all downlink symbols; the indicated identifier The second fourth time interval in the concatenation of 2 is configured such that the first 4 symbols are downlink symbols, and the remaining 10 symbols are uplink symbols, which means the next fourth time interval in which the first indication information is received The fourth time interval includes 4 downlink symbols and 10 uplink symbols, and the last two fourth time intervals are the same.
在本实施例中,可以是,该第三时间资源中的第一个第四时间间隔是接收到该第一指示信息的第四时间间隔。In this embodiment, it may be that the first fourth time interval in the third time resource is the fourth time interval for receiving the first indication information.
例如,第三时间资源为网络设备信道占用时间的资源,当第一指示域指示标识信息为2的级联时,表示第三时间资源的时间长度为包括接收到该第一指示信息的第四时间间隔在内的连续4个第四时间间隔。因此,UE可以在指示的下行符号上接收网络设备发送的下行传输,并且在共享网络设备信道占用时间内的上行符号发送上行传输,在共享网络设备信道占用时间内的上行符号传输信号时,UE可以采用较短的信道检测方式,例如,采用20us检测时间的信道接入方式,或者不检测信道而直接发送上行信号。For example, the third time resource is the resource for the time occupied by the channel of the network device. When the first indicator field indicates the cascade with the identification information of 2, it indicates that the time length of the third time resource is the fourth time including receiving the first indicator information. 4 consecutive fourth time intervals including the time interval. Therefore, the UE can receive the downlink transmission sent by the network device on the indicated downlink symbol, and send the uplink transmission on the uplink symbol within the time occupied by the channel of the shared network device. When the UE transmits the signal on the uplink symbol within the time occupied by the channel of the shared network device, A shorter channel detection method can be used, for example, a channel access method with a 20us detection time, or the uplink signal is sent directly without detecting the channel.
在本实施例中,也可以是,该第一指示信息还包含第二指示域,通过该第二指示域确定该第三时间资源中的第一时间资源。In this embodiment, it may also be that the first indication information further includes a second indication field, and the first time resource in the third time resource is determined through the second indication field.
例如,该第二指示域指示该第三时间资源中的第一个第四时间间隔开始属于该第一时间资源的连续的第四时间间隔的个数。For example, the second indication field indicates the number of consecutive fourth time intervals that belong to the first time resource from the first fourth time interval in the third time resource.
图8是本发明实施例1的第一指示信息指示的指示内容的另一示意图。如图8所示,第二指示域指示第三时间资源为2个第四时间间隔的时间。则第一指示域指示的标识信息为2的级联中前2个第四时间间隔即包括接收到第一指示信息的第四时间间隔的连续两个第四时间间隔为第三时间资源,该级联中的后2个第四时间间隔在第三时间资源以外,其指示的上行和/或下行符号的结构为第三时间资源外的连续2个第四时间间隔的上行和/或下行符号结构。FIG. 8 is another schematic diagram of the instruction content indicated by the first instruction information in Embodiment 1 of the present invention. As shown in FIG. 8, the second indication field indicates that the third time resource is the time of two fourth time intervals. Then the first two fourth time intervals in the cascade where the identification information indicated by the first indication field is 2, that is, two consecutive fourth time intervals including the fourth time interval in which the first indication information is received, are the third time resources. The last two fourth time intervals in the concatenation are outside the third time resource, and the structure of the indicated uplink and/or downlink symbols is two consecutive uplink and/or downlink symbols of the fourth time interval outside the third time resource structure.
例如,第三时间资源为网络设备信道占用时间的资源,当UE被调度在第三时间资源内的第2个第四时间间隔内的上行符号发送信号时,UE可以采用20us检测时间 的信道接入方式或不检测信道而直接接入信道发送上行信号。而UE在第三时间资源以外的下行符号上接收下行信号,在上行符号上不接收下行信号,且如果在该上行符号上调度了UE发送上行信号,需要采用网络设备指示的信道接入类型接入信道,而不能够采用20us检测时间的信道接入方式或不检测信道直接接入信道。For example, the third time resource is the resource occupied by the channel of the network device. When the UE is scheduled to transmit signals on the uplink symbol in the second and fourth time intervals in the third time resource, the UE can use the channel connection with a detection time of 20 us. Or directly access the channel without detecting the channel to send the uplink signal. The UE receives downlink signals on downlink symbols other than the third time resource, and does not receive downlink signals on uplink symbols. If the UE is scheduled to transmit uplink signals on the uplink symbol, it needs to use the channel access type indicated by the network device to connect. Into the channel, it is not possible to use the channel access method with 20us detection time or directly access the channel without detecting the channel.
也可以是,该第二指示域指示该第三时间资源中的最后一个第四时间间隔终止之前不属于该第一时间资源的时间长度。例如,该时间长度是以下的至少一个:至少一个第四时间间隔、整数倍个毫秒的时间间隔以及整数个符号。It may also be that the second indication field indicates the length of time that does not belong to the first time resource before the last fourth time interval in the third time resource expires. For example, the time length is at least one of the following: at least one fourth time interval, a time interval of an integer multiple of milliseconds, and an integer number of symbols.
另外,还可以是,该无线资源控制消息还包含与该第四时间间隔的级联相对应的信道接入优先级的配置信息。图9是本发明实施例1的无线资源控制配置消息的内容的另一示意图。如图9所示,该无线资源控制消息还包含与该第四时间间隔的级联相对应的信道接入优先级的配置信息,即标识为0~3的级联的优先级分别为1、1、2、4。In addition, it may also be that the radio resource control message further includes channel access priority configuration information corresponding to the concatenation of the fourth time interval. FIG. 9 is another schematic diagram of the content of a radio resource control configuration message according to Embodiment 1 of the present invention. As shown in FIG. 9, the radio resource control message also includes configuration information of the channel access priority corresponding to the cascade of the fourth time interval, that is, the priority of the cascades identified as 0 to 3 are 1, respectively. 1, 2, 4.
当该第三时间资源的时间长度大于或等于该信道接入优先级允许的时间长度最大值时,该第一时间资源为该第三时间资源中从起始时间开始该信道接入优先级允许的时间长度的最大值长度的时间资源,当该第三时间资源的时间长度小于该优先级的最大值时,该第一时间资源是该第三时间资源。When the time length of the third time resource is greater than or equal to the maximum time length allowed by the channel access priority, the first time resource is the channel access priority allowed from the start time in the third time resource When the time length of the third time resource is less than the maximum value of the priority, the first time resource is the third time resource.
在本实施例中,可以是,第三时间资源与第一时间资源并不相同或并不完全相同,例如,该第三时间资源中的第一个第四时间间隔是接收到该第一指示信息所在的第二时间间隔内的第一个第四时间间隔,该第一时间资源中的第一个第四时间间隔是接收到该第一指示信息的第四时间间隔。In this embodiment, it may be that the third time resource is not the same or not exactly the same as the first time resource. For example, the first fourth time interval in the third time resource is that the first indication is received. The first fourth time interval within the second time interval in which the information is located, and the first fourth time interval in the first time resource is the fourth time interval for receiving the first indication information.
图10是本发明实施例1的第一指示信息指示的指示内容的又一示意图。如图10所示,第一指示域指示的第三时间资源中的第一个第四时间间隔是接收到该第一指示信息所在的第二时间间隔内的第一个第四时间间隔,而第一时间资源中的第一个第四时间间隔是接收到该第一指示信息的第四时间间隔。FIG. 10 is another schematic diagram of the instruction content indicated by the first instruction information in Embodiment 1 of the present invention. As shown in FIG. 10, the first fourth time interval in the third time resource indicated by the first indication field is the first fourth time interval within the second time interval in which the first indication information is received, and The first fourth time interval in the first time resource is the fourth time interval for receiving the first indication information.
例如,该第一指示域指示的该标识对应的第四时间间隔的级联的结束点为该第一时间资源的结束点。例如,图10中的标识2对应的级联的结束点为第一时间资源的结束点。For example, the end point of the concatenation of the fourth time interval corresponding to the identifier indicated by the first indication field is the end point of the first time resource. For example, the end point of the cascade corresponding to the identifier 2 in FIG. 10 is the end point of the first time resource.
这样,减小了信道占用时间内多次发送第一指示信息需要指示不同的标识信息的级联而造成高层信令配置的大量开销。In this way, a large amount of overhead for high-level signaling configuration caused by the cascading of different identification information required to be sent for multiple times during the channel occupation time is reduced.
又例如,该第一指示信息还包含第三指示域,该第三指示域指示该第一时间资源的结束时间。该第三指示域指示该第一时间资源的时间长度,或者,该第一时间资源的结束点相对于该第三时间资源的结束点的时间长度。For another example, the first indication information further includes a third indication field, and the third indication field indicates the end time of the first time resource. The third indication field indicates the time length of the first time resource, or the time length of the end point of the first time resource relative to the end point of the third time resource.
另外,在本实施例中,该第一指示信息还可以包含一个使能域,该使能域指示是否改写上一次接收到的第一指示信息指示的上行和/或下行符号。In addition, in this embodiment, the first indication information may also include an enable field indicating whether to rewrite the uplink and/or downlink symbols indicated by the first indication information received last time.
例如,该使能域中的“0”表示第一次配置该第三时间资源以及该第三时间资源包含的上行和/或下行符号,或者,不改写前一次接收到的第一指示信息指示的上行和/或下行符号;该使能域中的“1”表示将改写前一次接收到的第一指示信息指示的该第三时间资源中的上行和/或下行符号。For example, "0" in the enable field indicates that the third time resource and the uplink and/or downlink symbols contained in the third time resource are configured for the first time, or the first indication information received previously is not rewritten. The “1” in the enable field means that the uplink and/or downlink symbols in the third time resource indicated by the first indication information received last time will be overwritten.
由上述实施例可知,通过在第一时间资源上和第一时间资源以外的第二时间资源上以不同的时间间隔来检测指示该第一时间资源以及该第一时间资源上的上行和/或下行符号的指示信息,和/或,通过仅在一个第一频域单元内接收该第一指示信息,能够提高检测和接收该指示信息的效率,并可以根据实际需要,灵活的确定检测和接收该指示信息的方式,另外,可以根据实际需要灵活的指示是否更新上行和/或下行符号的格式。It can be seen from the above embodiment that the first time resource and the uplink and/or uplink and/or on the first time resource are detected and indicated at different time intervals on the first time resource and the second time resource other than the first time resource. The indication information of the downlink symbol, and/or, by receiving the first indication information in only one first frequency domain unit, the efficiency of detecting and receiving the indication information can be improved, and the detection and reception can be flexibly determined according to actual needs In addition, the manner of indicating information can flexibly indicate whether to update the format of uplink and/or downlink symbols according to actual needs.
