Definitions
- Embodiments of the present application relate to the field of Internet of Things communications, and in particular, to a data transmission method, device, system, and storage medium.
- a narrowband Internet of Things (NB-IoT) system is a typical Internet of Things (IoT) system, which includes multiple terminal devices and network devices that provide communication services for the multiple terminal devices.
- IoT Internet of Things
- the NB-IoT system needs to support a larger coverage area.
- Network devices have different coverage conditions for terminal devices in different deployment environments. For terminal devices under different coverage conditions, the number of repetitions (that is, the number of repeated transmissions) required for downlink transmission is different.
- the coverage condition is related to the wireless channel quality of the terminal device and the distance between the terminal device and the network device.
- the NB-IoT system defines two types of downlink physical channels: narrowband physical downlink control channel (NPDCCH) and narrowband physical downlink shared channel (NPDSCH).
- NPDCCH narrowband physical downlink control channel
- NPDSCH narrowband physical downlink shared channel
- NPDSCH corresponding to different terminal devices is transmitted in a time division multiplexing (TDM) manner, and NPDCCH and NPDSCH are also transmitted in a TDM manner.
- TDM time division multiplexing
- NPDCCH and NPDSCH are also transmitted in a TDM manner.
- TDM time division multiplexing
- the network device determines the time period for the downlink transmission of the terminal device.
- the network device determines whether there is a gap in the GAP. If there is a gap, the network device does not perform downlink transmission with the terminal device in the gap, and continues to perform downlink transmission with the terminal device after the gap.
- the terminal device determines whether there is a gap in the time period used for downlink transmission. If there is a gap, the terminal device does not receive downlink transmission in the gap, and continues to receive downlink transmission after the gap. This processing of network equipment and terminal equipment is also called delayed transmission.
- Downlink transmission includes transmission of NPDCCH and transmission of NPDSCH.
- the maximum number of repetitions R max of the NPDCCH search space is usually compared with the interval threshold N gap, threshold configured by the NB-IoT system to determine whether there is a gap in the NPDCCH transmission. If R max is greater than or equal to N gap, threshold , There is a gap in the transmission of the NPDCCH. If R max is less than N gap, threshold , there is no gap in the transmission of the NPDCCH.
- a manner of determining whether there is a gap in the transmission of NPDSCH is the same as a manner of determining whether there is a gap in the transmission of NPDCCH. Wherein, whether there is gap in NPDCCH transmission refers to whether there is gap in the time period used for NPDCCH transmission, and whether there is gap in NPDSCH transmission refers to whether there is gap in the time period used for NPDSCH transmission.
- Downlink data is transmitted in the form of a transport block (TB) during actual transmission.
- the downlink data may be split into multiple TBs for transmission. .
- the TB is carried on the NPDSCH for transmission.
- the subsequent evolution of NB-IoT Specification 13 has evolved from supporting only one DCI to schedule one TB to supporting one DCI to schedule multiple TBs.
- R max is less than N gap, threshold , there is no gap in the time period used for downlink transmission, so the downlink transmission will not be delayed.
- the total duration of NPDSCH transmissions carrying multiple TBs may be large, which results in the NPDSCH transmissions carrying multiple TBs occupying the downlink channel for a long time, which results in the downlink channel being blocked and affecting the downlink transmission of other terminal equipment. Therefore, a new gap determination method is urgently needed to avoid continuous downlink transmission for a long duration to a terminal device, thereby preventing the downlink channel from being blocked.

- MTC Machine type communication
- M2M machine-to-machine
- IoT Internet-to-machine
- MTC may cover smart meter reading, medical detection monitoring, logistics detection monitoring, industrial detection monitoring, automotive networking, smart communities, and wearable device communications.
- the Internet of Things industry structured around MTC is considered to be the fourth wave in the information industry after computers, the Internet, and mobile communications networks, and is the future direction of wireless networks.
- the MTC system based on the cellular network infrastructure is an important type of MTC system.
- This type of MTC system is often called a Cellular MTC system or a Cellular IoT (CIoT) system.
- the 3rd Generation Partnership Project (3rd Generation Partnership Project) (3GPP) standards organization has always paid attention to the development of the Cellular MTC system and actively carried out the standardization of related technologies.
- the Cellular MTC system includes network equipment and terminal equipment.
- Network equipment can be MTC base stations
- terminal equipment can be MTC equipment
- MTC equipment is also called M2M equipment or IoT equipment.
- the requirements of the Cellular MTC system for network equipment and terminal equipment include the following four aspects:
- the first aspect network equipment has a large coverage area: MTC services require network equipment to support a large coverage area. Specifically, it is required that the network equipment has a strong coverage enhancement technology and can provide communication services for terminal equipment with a large penetration loss (for example, a penetration loss of 20 dB). For example, terminal devices in smart home and smart meter reading services such as smart water meters and smart meters are usually deployed indoors or in the basement. The Cellular MTC system requires network equipment to provide robust communication services for terminal devices deployed in the indoor and basement.
- network devices have a very high number of connections: network devices may be deployed on a large scale (more than tens of thousands or even hundreds of thousands) with terminal devices such as smart homes, smart communities, surveillance, automobiles, and wearable devices. Network devices need to provide communication services for large-scale deployed terminal devices while preventing network congestion.
- the terminal equipment has a low cost (low cost): the cost of the terminal equipment needs to be lower than the cost of existing mobile terminals to meet the conditions that the terminal equipment can be deployed on a large scale.
- terminal equipment has low power consumption (low power consumption): due to the diversity of terminal equipment and the diversity of the deployment environment of terminal equipment, terminal equipment is generally battery-powered, and it will be expensive to replace batteries for a large number of terminal equipment Extremely high labor cost and time cost, therefore, each functional device of the terminal device is required to have extremely low power consumption. In this way, the terminal device can have a longer standby time to reduce the number of battery replacements.
- MTC system is also called M2M system or IoT system.
- NB-IoT system is a typical IoT system.
- network devices In NB-IoT system, network devices have different coverage conditions for terminal devices in different deployment environments. Network devices are based on coverage conditions. Use different scheduling strategies to schedule terminal devices deployed in different environments. Among them, the coverage condition is related to the wireless channel quality of the terminal device and the distance between the terminal device and the network device. For example, the wireless channel quality of the terminal equipment in the center of the cell is better, and the coverage conditions of these terminal equipment by the network equipment are better.
- the network equipment can establish a reliable communication link with these terminal equipment using a small transmission power, so Network devices can use large code blocks, high-order modulation, and carrier bonding to quickly complete data transmission with these terminal devices; for example, the wireless channel quality of terminal devices at the cell edge or basement is poor, and network devices The coverage conditions of these terminal devices are poor. Network devices use large transmit power to establish communication links with these terminal devices. Therefore, network devices need to use technologies such as small code blocks, low-order modulation, repeated transmission, and spreading. Means to complete the data transmission with these terminal equipment.
- the NB-IoT system introduces the concept of coverage level to distinguish terminal devices with different coverage conditions.
- each terminal device corresponds to a coverage level.
- the coverage conditions of terminal devices at the same coverage level are the same or similar.
- Network devices can use the same or similar scheduling parameters to schedule terminal devices at the same coverage level.
- the coverage level introduced by the NB-IoT system includes three coverage levels: “ordinary coverage”, “edge coverage” and “extended coverage”.
- the coverage level of terminal devices closer to the network device may be “ordinary coverage”.
- the number of repetitions may be non-repeating; the coverage level of the terminal device far from the network device may be "edge coverage", and the network device repeats when transmitting data with these terminal devices.
- the number of times can be medium; the coverage level of the terminal equipment in the deployment environment such as the basement is "extended coverage”.
- the number of repetitions may be hundreds or even thousands of times.
- the number of repetitions refers to the number of repeated transmissions.
- the terminal device can select an appropriate number of repetitions for data transmission according to its corresponding coverage level to reduce unnecessary repeated transmissions and reduce power overhead.
- the NB-IoT system defines two types of downlink physical channels, namely NPDCCH and NPDSCH.
- NPDCCH is used to carry DCI
- NPDSCH is used to carry downlink data.
- Downlink data is usually transmitted in the form of TB.
- NPDSCH is used to carry downlink data, which is NPDSCH.
- NPDCCH is used to schedule NPDSCH (that is, DCI is used to schedule TB).
- the system bandwidth of the NB-IoT system is 180 kilohertz (kHz), the bandwidth occupied by NPDSCH transmission is 180 kHz, and the bandwidth occupied by NPDCCH transmission is 90 kHz or 180 kHz.
- the NPDCCH and NPDSCH corresponding to the same terminal device are transmitted in TDM, the NPDSCH corresponding to different terminal devices are transmitted in TDM, and the NPDCCH corresponding to different terminal devices is transmitted in TDM or frequency division multiplexing (FDM).
- FIG. 1 shows a schematic diagram of NPDCCH scheduling for NPDSCH according to an embodiment of the present application.
- the meaning of the arrow is that the NPDSCH pointed by the arrow is scheduled by the NPDCCH without the arrow.
- This FIG. 1 uses terminal equipment as a user equipment (User Equipment, UE) for illustration.
- UE User Equipment

- the NPDCCH corresponding to UE2 and the NPDSCH corresponding to UE2 are transmitted in TDM

- the corresponding NPDSCH is transmitted in a TDM manner
- the NPDSCH corresponding to UE1 and the NPDSCH corresponding to UE3 are transmitted in a TDM manner
- the NPDSCH corresponding to UE2 and the NPDSCH corresponding to UE3 are transmitted in a TDM manner.
- the terminal device needs to monitor an NPDCCH candidate set to obtain DCI.
- the NPDCCH candidate set is called an NPDCCH search space (SS), and resources of the search space are periodically distributed.
- the network device may indicate to the terminal device the period of the search space (that is, the length of the period of the search space in the time domain) and the search space within each period by using a system message or radio resource control (RRC) signaling.
- RRC radio resource control
- the terminal device blindly detects the NPDCCH in the search space according to the instruction of the network device.
- the system message or RRC signaling carries parameters R max , G, and ⁇ offset .
- R max represents the maximum number of repetitions of the NPDCCH search space.
- the terminal device After receiving the system message or RRC signaling, the terminal device multiplies the product of R max and G by Determine the period of the search space, determine R max as the duration of the search space in the period of each search space, and determine the product of R max , G, and ⁇ offset as the starting position of the period of the search space and search The interval of the starting position of the space in the time domain.
- G * R max * ⁇ offset represents the length of the G * R max * ⁇ offset offset from the starting position of the period of the search space in the time domain.
- the cycle search space is G * R max
- the interval between the start position of the search space period and the start position of the search space in the time domain is G * R max * ⁇ offset .
- each candidate in the time domain is equal to R max / 8 (that is, R max of 8) effective subframes, and the length of each candidate in the 8th to 11th candidates in the time domain Equal to R max / 4 (ie, R max 1/4) effective sub-frames, and the length of each candidate in the 12th to 13th candidates in the time domain is equal to R max / 2 (that is, 2/2 R max ) effective subframes, and the length of the 14th candidate in the time domain is equal to R max effective subframes.
- the downlink transmission of a terminal device with poor coverage conditions needs to be repeated hundreds or even thousands of times, so the downlink transmission of a terminal device with poor coverage conditions takes a long time.
- the NPDSCH corresponding to different terminal equipment can only be transmitted in TDM mode, if the downlink transmission of the terminal equipment with poor coverage conditions occupies the channel, the downlink transmission of the terminal equipment with better coverage conditions must wait until the downlink of the terminal equipment with poor coverage conditions The transmission can only be performed after the end of the transmission. Therefore, the downlink transmission of the terminal equipment with poor coverage conditions will block the downlink transmission of the terminal equipment with poor coverage conditions.
- NB-IoTRel-13 introduced the concept of gap.
- the network device determines whether there is a gap in the time period used for the downlink transmission of the terminal device. If there is a gap, the network device does not include the gap in the gap. Perform downlink transmission with the terminal device, and continue to perform downlink transmission with the terminal device after the gap. The terminal device determines whether there is a gap in the time period used for downlink transmission. If there is a gap, the terminal device does not receive downlink transmission in the gap, and continues to receive downlink transmission after the gap.
- Downlink transmission includes transmission of NPDCCH and transmission of NPDSCH.
- the maximum number of repetitions R max of the NPDCCH search space is usually compared with the interval threshold N gap, threshold configured by the NB-IoT system to determine whether there is a gap in the NPDCCH transmission. If R max is greater than or equal to N gap, threshold , There is a gap in the transmission of the NPDCCH. If R max is less than N gap, threshold , there is no gap in the transmission of the NPDCCH.
- a manner of determining whether there is a gap in the transmission of NPDSCH is the same as a manner of determining whether there is a gap in the transmission of NPDCCH. Among them, the gap is distributed periodically.
- the network device can configure gap configuration parameters.
- the gap configuration parameters include gap interval threshold N gap, threshold , gap period N gap, period, and gap duration factor N gap, coff .
- the gap can also be called downlink (DL) gap.
- Network devices can configure the interval threshold N gap, threshold by the parameter dl-GapThreshold, and configure the gap period N gap, period of the gap by the parameter dl-GapPeriodicity.
- GapDurationCoeff configures gap duration factors N gap, coff , N gap, threshold , N gap, period, and N gap, coff . The range of values is shown in Table 1 below:
- the maximum number of repetitions R max1 search space NPDCCH hypotheses corresponding to the UE1 is greater than or equal to the interval threshold N gap, threshold, UE2 of NPDCCH search space maximum
- the number of repetitions R max2 is less than the interval threshold N gap, threshold , then there is a gap in the transmission of NPDCCH and NPDSCH corresponding to UE1, and there is no gap in the transmission of NPDCCH and NPDSCH corresponding to UE2.
- An intuitive understanding can be seen: UE1 can see gap, and the gap is transparent to UE2 (that is, the gap cannot be seen by UE2).
- the NPDCCH transmission and NPDSCH transmission corresponding to UE1 need a high number of repetitions, and the NPDCCH transmission and NPDSCH transmission corresponding to UE2 need a small number of repetitions or No repetition is needed.
- the transmission of the NPDSCH corresponding to UE1 includes the first part and the second part. Because the resources of the second part overlap with the resources of the gap, the second part is postponed to be transmitted after the gap.
- the NPDCCH and NPDSCH corresponding to UE2 can be transmitted within the gap without waiting for the transmission of UE1 to complete. Since the NPDCCH and NPDSCH corresponding to UE2 can be transmitted within the gap without waiting for the transmission of UE1 to complete, the introduction of gaps can avoid the downlink channel being blocked .
- downlink data may be split into multiple TBs for transmission based on the amount of business data and the TB size limit imposed by the NB-IoT system.
- the subsequent evolution of NB-IoT Rel-13 evolved from supporting only one DCI to scheduling one TB to supporting one DCI to schedule multiple TBs.
- the maximum repetition number R max of the search space of the NPDCCH corresponding to the terminal device is less than the interval threshold N gap, threshold . According to the existing gap determination method, there is no gap in the NPDCCH transmission and NPDSCH transmission corresponding to the terminal device.
- FIG. 4 is a schematic diagram of scheduling multiple TBs by one DCI provided in the related art. Referring to FIG. 4, one DCI schedules four TBs, and the total duration of NPDSCH transmission carrying the four TBs is large.
- this embodiment of the present application provides a new gap determination method that can schedule multiple TBs in a DCI.

Description
本申请实施例涉及物联网通信领域,特别涉及一种数据传输方法、设备及***、存储介质。
窄带物联网(narrowband internet of things,NB-IoT)***是一种典型的物联网(internet of things,IoT)***,其包括多个终端设备和为该多个终端设备提供通信服务的网络设备。考虑终端设备的不同部署环境,比如室外,室内和地下室等部署环境,NB-IoT***需要支持较大的覆盖范围。网络设备对不同部署环境中的终端设备的覆盖条件不同,对于不同覆盖条件下的终端设备,在进行下行传输时所需要的重复次数(也即是重复传输的次数)不同。其中,覆盖条件和终端设备的无线信道质量以及终端设备与网络设备之间的距离有关。
NB-IoT***定义了两种下行物理信道,分别为窄带物理下行控制信道(narrowband physical downlink control channel,NPDCCH)和窄带物理下行共享信道(narrowband physical downlink shared channel,NPDSCH),NPDCCH用于承载下行控制信息(downlink control information,DCI),NPDSCH用于承载下行数据。
在NB-IoT***中,不同终端设备对应的NPDSCH以时分复用(time division multiplexing,TDM)的方式传输,NPDCCH和NPDSCH也以TDM的方式传输。对于覆盖条件较差(例如无线信道质量较差)的终端设备,为了保证传输的可靠性,在进行下行传输时需要较多的重复次数,从而该覆盖条件较差的终端设备的下行传输会长时间占用下行信道,导致下行信道受阻。为此,NB-IoT规范13引入间隔(gap)的概念,网络设备与终端设备进行下行传输的过程中,针对该终端设备的下行传输,网络设备确定用于该终端设备的下行传输的时间段中是否有gap,若有gap,则网络设备在该gap中不与该终端设备进行下行传输,且在该gap后继续与该终端设备进行下行传输。终端设备确定用于下行传输的时间段中是否有gap,若有gap,则该终端设备在该gap中不进行下行传输的接收,且在该gap后继续进行下行传输的接收。网络设备和终端设备的这种处理也被称为推迟传输。
下行传输包括NPDCCH的传输和NPDSCH的传输。目前,通常是将NPDCCH的搜索空间的最大重复次数R
max与NB-IoT***配置的间隔门限N
gap,threshold进行比较来确定NPDCCH的传输中是否有gap,如果R
max大于或者等于N
gap,threshold,则NPDCCH的传输中有gap,如果R
max小于N
gap,threshold,则NPDCCH的传输中没有gap。NPDSCH的传输中是否有gap的确定方式与NPDCCH的传输中是否有gap的确定方式相同。其中,NPDCCH的传输中是否有gap指的是用于NPDCCH传输的时间段中是否有gap,NPDSCH的传输中是否有gap指的是用于NPDSCH传输的时间段中是否有gap。
下行数据在实际传输时是按照传输块(transportblock,TB)的方式传输的,根据业务数据量的大小以及NB-IoT***对TB大小的限制,可能会将下行数据拆分成多个TB进行 传输。其中,TB承载在NPDSCH上进行传输。NB-IoT规范13后续演进版本从只支持一个DCI调度一个TB发展到支持一个DCI调度多个TB。在一个DCI调度多个TB的场景下,按照现有的gap确定方式,如果R
max小于N
gap,threshold,则用于下行传输的时间段中没有gap,因此不会推迟下行传输。但是承载多个TB的NPDSCH传输的总时长可能较大,导致承载多个TB的NPDSCH传输长时间占用下行信道,从而导致下行信道受阻,影响其它终端设备的下行传输。因此亟需一种新的gap确定方式,以避免针对一个终端设备持续时间较长的连续下行传输,进而避免下行信道受阻。

本申请实施例提供的技术方案的有益效果是:
本申请实施例提供的数据传输方法、设备及***、存储介质,网络设备根据第一参数和第一间隔门限确定下行控制信道的传输中是否有间隔,根据下行控制信道的传输中是否有间隔的确定结果,通过下行控制信道向终端设备发送下行控制信息,根据第二参数和第二间隔门限确定下行数据信道的传输中是否有间隔,根据下行数据信道的传输中是否有间隔的确定结果,通过下行数据信道向终端设备发送一个或多个传输块,第一参数和第二参数不同且第一间隔门限和第二间隔门限相同,或者,第一参数和第二参数相同且第一间隔门限和第二间隔门限不同,或者,第一参数和第二参数不同且第一间隔门限和第二间隔门限不同。本申请实施例提供的方案使得针对下行控制信道和下行数据信道的传输是否有间隔,可以采用不同的判断方式,从而使得相同时间段用于发送下行数据信道时所包括的间隔数能够不同于该相同时间段用于发送下行控制信道时所包括的间隔数,具体可以使得相同时间段用于发送下行数据信道时所包括的间隔数能够不少于该相同时间段用于发送下行控制信道时所包括的间隔数。从而,相比于目前的gap确定方式,本申请实施例提供的gap确定方式能够使得下行数据信道的传输中具有更多的间隔,因此在一个DCI调度多个TB的场景下,可以更好地避免针对一个终端设备持续时间较长的连续下行数据传输,从而更好地避免下行信道受阻。

为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施例实施方式作进一步地详细描述。
机器类型通信(machine type communication,MTC)又称为机器间(machine to machine,M2M)通信或者IoT通信,将是未来通信领域的一项重要应用。未来MTC可能涵盖智能抄表、医疗检测监控、物流检测监控、工业检测监控、汽车联网、智能社区以及可穿戴设备通信等。围绕MTC构造的物联网产业被认为是信息产业中,继计算机、互联网和移动通信网之后的第四次浪潮,是未来无线网络的发展方向。
基于蜂窝网络基础架构的MTC***是一类重要的MTC***,这一类MTC***通常称为Cellular MTC***或者Cellular IoT(CIoT)***。第三代合作伙伴计划(3rd generation partnership project,3GPP)标准组织一直关注Cellular MTC***的发展,并积极开展相关技术的标准化。Cellular MTC***包括网络设备和终端设备,网络设备可以为MTC基站,终端设备可以为MTC设备,MTC设备又称为M2M设备或IoT设备。目前,Cellular MTC***对网络设备和终端设备的需求包括以下四个方面:
第一方面:网络设备具有较大的覆盖范围:MTC业务需要网络设备能够支持较大的覆盖范围。具体地,需要网络设备具有较强的覆盖增强技术,能够为较大穿透损耗(例如穿透损耗为20分贝)的终端设备提供通信服务。例如,诸如智能水表、智能电表等的智能家居、智能抄表服务中的终端设备通常部署在室内或地下室,Cellular MTC***要求网络设备能够为部署在室内和地下室的终端设备提供稳健的通信服务。
第二方面:网络设备具有极高的连接数:网络设备下可能大规模的部署(超过数万个甚至数十万个)有智能家居、智能社区、监控、汽车和可穿戴设备等终端设备,网络设备需要在防止网络拥塞的前提下,同时为大规模部署的终端设备提供通信服务。
第三方面:终端设备具有较低的成本(low cost):终端设备的成本需要低于现有的移动终端的成本,以满足终端设备能够大规模部署的条件。
第四方面:终端设备具有较低的功耗(low power consumption):由于终端设备的多样性以及终端设备的部署环境的多样性,终端设备一般采用电池供电,为大量的终端设备更换电池会耗费极高的人力成本和时间成本,因此要求终端设备的各功能器件具有极低的功耗,这样一来,终端设备可以有更长的待机时间,以减少更换电池的次数。
MTC***又称为M2M***或者IoT***,NB-IoT***是一种典型的IoT***,在NB-IoT***中,网络设备对不同部署环境中的终端设备的覆盖条件不同,网络设备基于覆盖条件使用不同的调度策略对部署在不同环境中的终端设备进行调度。其中,覆盖条件和终端设备的无线信道质量以及终端设备与网络设备之间的距离有关。例如,处于小区中心位置的终端设备的无线信道质量较好,网络设备对这些终端设备的覆盖条件较好,网络设备使用较小的发送功率就能与这些终端设备建立可靠的通信链路,因此网络设备可以使用大码块、高阶调制和载波绑定等技术手段快速完成与这些终端设备之间的数据传输;又例如,处于小区边缘或者地下室的终端设备的无线信道质量较差,网络设备对这些终端设备的覆盖条件较差,网络设备使用较大的发送功率才能与这些终端设备建立通信链路,因此网络设备需要使用小码块、低阶调制、多次重复发送和扩频等技术手段才能完成与这些终端设备之间的数据传输。
为了保证通信的可靠性,节省发送功率,NB-IoT***引入覆盖等级的概念对不同覆盖条件的终端设备进行区分。在NB-IoT***中,每个终端设备对应一个覆盖等级,处于同一覆盖等级的终端设备的覆盖条件相同或相似,网络设备可以采用相同或相似的调度参数对处于同一覆盖等级的终端设备进行调度。示例地,NB-IoT***引入的覆盖等级包括“普通覆盖”、“边缘覆盖”和“扩展覆盖”这三个覆盖等级,距离网络设备较近的终端设备的覆盖等级可以为“普通覆盖”,网络设备在与这些终端设备进行数据传输时,重复次数可以为不重复;距离网络设备较远的终端设备的覆盖等级可以为“边缘覆盖”,网络设备在与这些终端设备进行数据传输时,重复次数可以为中等;处于地下室等部署环境的终端设备的覆盖等级为“扩展覆盖”,网络设备在与这些终端设备进行数据传输时,重复次数可能高达几百次甚至上千次。其中,重复次数指的是重复传输的次数,终端设备可以根据自身对应的覆盖等级选择合适的重复次数进行数据传输,以降低不必要的重复传输,减少功率开销。
NB-IoT***定义了两种下行物理信道,分别为NPDCCH和NPDSCH,NPDCCH用于承载DCI,NPDSCH用于承载下行数据,下行数据通常以TB的形式传输,NPDSCH用于承载下行数据也即是NPDSCH用于承载TB,NPDCCH用于调度NPDSCH(也即是DCI用于调度TB)。NB-IoT***的***带宽为180千赫兹(kHz),NPDSCH的传输占用的带宽为180kHz,NPDCCH的传输占用的带宽为90kHz或者180kHz。同一终端设备对应的NPDCCH和NPDSCH以TDM的方式传输,不同终端设备对应的NPDSCH以TDM的方式传输,不同终端设备对应的NPDCCH以TDM或频分复用(frequency division multiplexing,FDM)的方式传输。请参考图1,其示出了本申请实施例所涉及的一种NPDCCH调度NPDSCH的示意图,箭头所代表的含义为:箭头指向的NPDSCH是由无箭头一端的NPDCCH调度的。该图1以终端设备为用户设备(User Equipment,UE)进行说明。参见图1,UE1对应的NPDCCH与UE1对应的NPDSCH以TDM的方式传输,UE2对应的NPDCCH与UE2对应的NPDSCH以TDM的方式传输,UE3对应的NPDCCH与UE3对应的NPDSCH以TDM的方式传输,UE1对应的NPDCCH与UE2对应的NPDCCH以TDM的方式传输,UE1对应的NPDCCH与UE3对应的NPDCCH以TDM的方式传输,UE2对应的NPDCCH与UE3对应的NPDCCH以FDM的方式传输,UE1对应的NPDSCH与UE2对应的NPDSCH以TDM的方式传输,UE1对应的NPDSCH与UE3对应的NPDSCH以TDM的方式传输, UE2对应的NPDSCH与UE3对应的NPDSCH以TDM的方式传输。
终端设备需要监听一个NPDCCH候选集合以获取DCI,该NPDCCH候选集合称为NPDCCH搜索空间(search space,SS),搜索空间的资源周期性分布。网络设备可以通过***消息或者无线资源控制(radio resource control,RRC)信令向终端设备指示搜索空间的周期(也即是搜索空间的周期在时域上的长度)和搜索空间在每个周期内的起始位置,终端设备根据网络设备的指示在搜索空间内盲检测NPDCCH。其中,***消息或者RRC信令中携带参数R
max、G和α
offset,R
max表示NPDCCH的搜索空间的最大重复次数,终端设备接收到***消息或者RRC信令后,将R
max和G的乘积确定为搜索空间的周期,将R
max确定为搜索空间在每个搜索空间的周期内的持续时长,将R
max、G和α
offset三者的乘积确定为搜索空间的周期的起始位置与搜索空间的起始位置在时域上的间隔,G*R
max*α
offset表示在时域上从搜索空间的周期的起始位置向后偏移G*R
max*α
offset长度。一个搜索空间的周期内可以有多个NPDCCH候选。请参考图2,其示例出了本申请实施例所涉及的一种NPDCCH候选的示意图,搜索空间的周期为G*R
max,搜索空间在G*R
max内的持续时长为R
max个有效子帧,搜索空间的周期的起始位置与搜索空间的起始位置在时域上的间隔为G*R
max*α
offset,一个搜索空间的周期内有15个NPDCCH候选,第0至第7个候选中的每个候选在时域上的长度等于R
max/8(也即是8分之R
max)个有效子帧,第8至第11个候选中的每个候选在时域上的长度等于R
max/4(也即是4分之R
max)个有效子帧,第12至第13个候选中的每个候选在时域上的长度等于R
max/2(也即是2分之R
max)个有效子帧,第14个候选在时域上的长度等于R
max个有效子帧。
在NB-IoT***中,覆盖条件较差的终端设备的下行传输需要高达几百次甚至上千次的重复,从而覆盖条件较差的终端设备的下行传输需要较长的时间。由于不同终端设备对应的NPDSCH只能以TDM的方式传输,如果覆盖条件较差的终端设备的下行传输占用信道,覆盖条件较好的终端设备的下行传输要等到覆盖条件较差的终端设备的下行传输结束之后才能进行,因此,覆盖条件较差的终端设备的下行传输会阻塞覆盖条件较差好的终端设备的下行传输。为此,NB-IoTRel-13引入gap的概念。网络设备与终端设备进行下行传输的过程中,针对该终端设备的下行传输,网络设备确定用于该终端设备下行传输的时间段中是否有gap,若有gap,则网络设备在该gap中不与该终端设备进行下行传输,且在该gap后继续与该终端设备进行下行传输。终端设备确定用于下行传输的时间段中是否有gap,若有gap,则该终端设备在该gap中不进行下行传输的接收,且在该gap后继续进行下行传输的接收。
下行传输包括NPDCCH的传输和NPDSCH的传输。目前,通常是将NPDCCH的搜索空间的最大重复次数R
max与NB-IoT***配置的间隔门限N
gap,threshold进行比较来确定NPDCCH的传输中是否有gap,如果R
max大于或者等于N
gap,threshold,则NPDCCH的传输中有gap,如果R
max小于N
gap,threshold,则NPDCCH的传输中没有gap。NPDSCH的传输中是否有gap的确定方式与NPDCCH的传输中是否有gap的确定方式相同。其中,gap是周期性分布的,网络设备可以配置gap配置参数,gap配置参数包括gap的间隔门限N
gap,threshold、gap的周期N
gap,period和gap的持续时长因子N
gap,coff,在下行传输中,gap也可以称为下行(downlink,DL)gap,网络设备可以通过参数dl-GapThreshold配置间隔门限N
gap,threshold,通过参数dl-GapPeriodicity配置gap的周期N
gap,period,通过参数dl-GapDurationCoeff配置gap 的持续时长因子N
gap,coff,N
gap,threshold、N

gap,coff的取值范围如下表1所示:
表1

N gap,threshold | {32,64,128,256} |
N gap,period | {64,128,256,512} |
N gap,coff | {1/8,1/4,3/8,1/2} |
每个gap的周期内,gap的起始无线帧和起始子帧根据公式
确定,gap的持续时长根据公式N
gap,duration=N
gap,coff×N
gap,period确定,其中,n
f为无线帧号或***帧号,n
s为时隙号,mod表示取余或者取模运算,
表示取整运算。
图3是本申请实施例所涉及的一种下行信道的传输示意图,假设UE1对应的NPDCCH的搜索空间的最大重复次数R
max1大于或等于间隔门限N
gap,threshold,UE2的NPDCCH的搜索空间的最大重复次数R
max2小于间隔门限N
gap,threshold,则UE1对应的NPDCCH的传输和NPDSCH的传输中有gap,UE2对应的NPDCCH的传输和NPDSCH的传输中没有gap,直观的理解可以是:UE1可以看见gap,而gap对于UE2来说是透明的(也即是UE2看不见gap)。假设UE1的覆盖条件较差,UE2的覆盖条件较好,则UE1对应的NPDCCH的传输和NPDSCH的传输需要较高的重复次数,UE2对应的NPDCCH的传输和NPDSCH的传输需要较少的重复次数或者不需要重复,如图3所示,UE1对应的NPDSCH的传输包括第一部分和第二部分,由于第二部分的资源与gap的资源重叠,因此第二部分推迟(postpone)至gap之后传输。UE2对应的NPDCCH和NPDSCH可以在gap内传输,而不需要等待UE1传输完成,由于UE2对应的NPDCCH和NPDSCH可以在gap内传输,而不需要等待UE1传输完成,因此,引入gap可以避免下行信道受阻。
实际应用中,根据业务数据量的大小以及NB-IoT***对TB大小的限制,可能会将下行数据拆分成多个TB进行传输。为了提高调度效率,降低DCI开销,NB-IoT Rel-13后续演进版本从只支持一个DCI调度一个TB发展到支持一个DCI调度多个TB,在一个DCI调度多个TB的场景中,假设某一终端设备对应的NPDCCH的搜索空间的最大重复次数R
max小于间隔门限N
gap,threshold,按照现有的gap确定方式,该终端设备对应的NPDCCH的传输和NPDSCH的传输中都没有gap,对于一个DCI调度多个TB的场景,承载每个TB的NPDSCH的传输时长较短,但是承载多个TB的NPDSCH传输的总时长较大,导致承载多个TB的NPDSCH的传输长时间占用下行信道,影响其它终端设备的下行传输。例如,图4是相关技术提供的一种一个DCI调度多个TB的示意图,参见图4,一个DCI调度4个TB,承载该4个TB的NPDSCH的传输的总时长较大。
针对一个DCI调度多个TB的场景中,承载多个TB的NPDSCH的传输长时间占用下行信道的问题,本申请实施例提供了一种新的gap确定方式,可以在一个DCI调度多个TB的场景中,避免承载多个TB的NPDSCH的传输长时间占用下行信道,进而避免针对一个终端设备持续时间较长的连续下行传输,避免下行信道受阻,提高***资源利用效率。本申请实施例的详细方案请参考下述实施例。

步骤605、网络设备根据下行数据信道的传输中是否有间隔的确定结果,通过下行数据信道向终端设备发送一个或多个传输块。
网络设备可以根据下行数据信道的传输中是否有间隔的确定结果,将一个或多个传输块承载在下行数据信道中,然后通过下行数据信道向终端设备发送该一个或多个传输块。第一参数、第二参数、第一间隔门限和第二间隔门限使得相同时间段用于发送下行数据信道时所包括的间隔数不少于相同时间段用于发送下行控制信道时所包括的间隔数。
在本实施例中,假设第一参数和第二参数相同,第一间隔门限N
gap,threshold1和第二间隔门限N
gap,threshold2不同。第一参数为物理下行控制信道的搜索空间的最大重复次数R
max,第一间隔门限N
gap,threshold1和第二间隔门限N
gap,threshold2是***配置的。物理下行控制信道的搜索空间的最大重复次数R
max为16,第一间隔门限N
gap,threshold1配置为32,第二间隔门限N
gap,threshold2配置为8。由于第一参数R
max小于第一间隔门限N
gap,threshold1,因此下行控制信道的传输中没有间隔。由于第二参数R
max大于第二间隔门限N
gap,threshold2,因此下行数据信道的传输中有间隔。间隔是周期性出现的,如果对一定时间段的间隔进行计数,在本例中下行数据信道的传输中有间隔,下行控制信道的传输中没有间隔,因此第一参数、第二参数、第一间隔门限和第二间隔门限使得相同时间段用于发送下行数据信道时所包括的间隔数不少于相同时间段用于发送下行控制信道时所包括的间隔数。
可选地,如果下行数据信道的传输中有间隔,则网络设备根据公式

f为无线帧号或***帧号,n

表示取整运算。如果下行数据信道的传输中没有间隔,则下行数据信道可以在连续的有效子帧上传输,网络设备可以通过该连续的有效子帧向终端设备发送一个或多个传输块。需要说明的是:如果在下行数据信道的传输中有间隔,将下行数据信道推迟到间隔之后传输,由于一个或者多个传输块由下行数据信道承载,因此,可以理解为将该一个或多个传输块推迟至间隔之后向终端设备发送。

综上所述,本申请实施例提供的数据传输方法,根据第一参数和第一间隔门限确定下行控制信道的传输中是否有间隔,根据下行控制信道的传输中是否有间隔的确定结果,通 过下行控制信道与终端设备传输下行控制信息,根据第二参数和第二间隔门限确定下行数据信道的传输中是否有间隔,根据下行数据信道的传输中是否有间隔的确定结果,通过下行数据信道与终端设备传输一个或多个传输块,第一参数和第二参数不同且第一间隔门限和第二间隔门限相同,或者,第一参数和第二参数相同且第一间隔门限和第二间隔门限不同,或者,第一参数和第二参数不同且第一间隔门限和第二间隔门限不同。本申请实施例提供的方案使得针对下行控制信道和下行数据信道的传输是否有间隔,可以采用不同的判断方式,从而使得相同时间段用于发送下行数据信道时所包括的间隔数能够不同于该相同时间段用于发送下行控制信道时所包括的间隔数,具体可以使得相同时间段用于发送下行数据信道时所包括的间隔数能够不少于该相同时间段用于发送下行控制信道时所包括的间隔数。从而,相比于目前的gap确定方式,本申请实施例提供的gap确定方式能够使得下行数据信道的传输中具有更多的间隔,因此在一个DCI调度多个TB的场景下,可以更好地避免针对一个终端设备持续时间较长的连续下行数据传输,从而更好地避免下行信道受阻,提高***资源利用效率。此外,本申请实施例提供的数据传输方法,通过设置第二间隔门限来确定下行数据信道的传输中是否有间隔,相比于相关技术,该间隔确定方式更为灵活。
