具体实施方式Detailed ways
为了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作进一步地详细描述。In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
以下,对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。In the following, some terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
1)寻呼信令:用于寻呼一个或多个终端设备。 1) Paging signaling: used to page one or more terminal devices.
2)选择(select)信令:用于选择或寻呼一个或多个标签进行随机接入。2) Select signaling: used to select or page one or more tags for random access.
3)查询(Query)信令:用于触发标签接入网络。Query信令还可以用于指示标签随机接入的资源配置。示例性的,Query信令可以包括参数Q,参数Q用于标签计算最大发送时隙数以及随机选择一个接入时隙。标签可以根据参数Q计算最大接入的时隙范围,例如[0,2Q-1],标签可以在该范围内随机选择一个数值,保存为counter。标签每当接收一个Query信令(再次接收的Query信令可以称为QueryRep),则将counter的值更新为counter-1。当counter等于0时,标签可以发送一个随机数,如16位随机数(random number 16,RN16)。需要说明的是,读写器发送Query后所对应的时隙为0,则产生counter初始值为0的终端,可在收到Query后即可发起接入。3) Query signaling: used to trigger tags to access the network. Query signaling can also be used to indicate resource configuration for label random access. For example, Query signaling may include parameter Q, which is used by the tag to calculate the maximum number of sending time slots and randomly select an access time slot. The tag can calculate the maximum access time slot range based on the parameter Q, such as [0, 2Q-1]. The tag can randomly select a value within this range and save it as counter. Whenever the tag receives a Query signaling (the Query signaling received again can be called QueryRep), the value of counter is updated to counter-1. When counter is equal to 0, the tag can send a random number, such as a 16-bit random number (random number 16, RN16). It should be noted that if the corresponding time slot after the reader sends the Query is 0, a terminal with an initial counter value of 0 will be generated and can initiate access after receiving the Query.
4)RFID技术:标签进入磁场后,接收读写器发出的射频信号,通过感应电流所获得的能量发送出存储在芯片中的产品信息(如无源标签或被动标签等)。示例性的,请参见图1,为RFID系统的架构示意图,该RFID系统包括读写器(也可称为阅读器)、标签(tag)、以及天线。可以理解的是,天线有读写器天线和标签天线。4) RFID technology: After the tag enters the magnetic field, it receives the radio frequency signal from the reader and uses the energy obtained from the induced current to send out the product information stored in the chip (such as passive tags or passive tags, etc.). For example, please refer to Figure 1, which is a schematic architectural diagram of an RFID system. The RFID system includes a reader/writer (also called a reader), a tag, and an antenna. It can be understood that the antennas include reader antennas and tag antennas.
读写器,是一种能够获取和处理电子标签的数据的设备,它可以作为单独的设备,也可以嵌入至其它设备或系统中。读写器可以通过读写器天线向标签发送射频信号,以便向标签查询数据或写入数据。读写器还可以通过通信接口与其它设备(例如图1中计算机)连接,进而将读写器本地存储的数据或从标签中获取的数据传输至其它设备中。本申请实施例对读写器的具体形态不作限制。例如,读写器可以是终端设备,或者网络设备(如网络设备),或者一个具有读写功能的设备,或者其他可能形态的设备。应理解,图1中的计算机不是系统必须的,因此以虚线进行示意。A reader/writer is a device that can acquire and process data from electronic tags. It can be used as a standalone device or can be embedded in other devices or systems. The reader can send radio frequency signals to the tag through the reader antenna to query or write data to the tag. The reader/writer can also be connected to other devices (such as the computer in Figure 1) through the communication interface, thereby transmitting data stored locally by the reader/writer or data obtained from the tags to other devices. The embodiments of this application do not limit the specific form of the reader/writer. For example, the reader/writer can be a terminal device, or a network device (such as a network device), or a device with reading and writing functions, or other possible devices. It should be understood that the computer in Figure 1 is not necessary for the system, so it is illustrated with a dotted line.
标签,也可称为电子标签或RFID标签,是一种微型的无线收发装置,主要包括内置的标签天线、耦合元件以及芯片。芯片中具备能够支持读写器读取或写入标签数据的存储空间。标签通过标签天线接收到读写器发送的射频信号后,可以通过耦合元件实现对射频信号的耦合,进而在耦合通道内可以实现对标签的芯片提供能量、以及将芯片中存储的标签数据通过标签天线反馈给读写器。标签可以包括有源标签、无源标签和半有源标签三种。对于无源标签也可以称为是无源物联网(internet of things,IOT)设备。标签也可以看成一种终端设备。A tag, also known as an electronic tag or RFID tag, is a miniature wireless transceiver device, which mainly includes a built-in tag antenna, coupling element and chip. The chip has storage space that can support the reader to read or write tag data. After the tag receives the radio frequency signal sent by the reader through the tag antenna, it can couple the radio frequency signal through the coupling element, and then in the coupling channel, it can provide energy to the tag's chip and pass the tag data stored in the chip through the tag. The antenna feeds back to the reader. Tags can include active tags, passive tags and semi-active tags. Passive tags can also be called passive Internet of Things (IOT) devices. A tag can also be viewed as a terminal device.
5)标签的随机接入过程,如下A1~A所示:5) The random access process of tags is as shown below A1~A:
A1,读写器发送select信令,其中,select信令可以包含标签内存信息,用于选择或寻呼一个或多个标签进行随机接入。A1, the reader/writer sends select signaling, where the select signaling can contain tag memory information and is used to select or page one or more tags for random access.
A2,读写器发送Query信令用于指示标签随机接入的资源配置。示例性的,Query信令可以包括参数Q,参数Q用于标签计算最大发送时隙数以及随机选择一个接入时隙。A2, the reader/writer sends Query signaling to indicate the resource configuration of tag random access. For example, Query signaling may include parameter Q, which is used by the tag to calculate the maximum number of sending time slots and randomly select an access time slot.
A3,被寻呼到的标签(也就是符合select信令包含的标签内存信息的标签)随机选择一个随机接入机会或接入时隙向读写器发送随机接入请求。A3. The paged tag (that is, the tag that matches the tag memory information contained in the select signaling) randomly selects a random access opportunity or access time slot to send a random access request to the reader.
A4,若读写器成功接收随机接入请求,则反馈一个确认消息(ACK)。A4, if the reader successfully receives the random access request, it will feed back an acknowledgment message (ACK).
6)覆盖等级:网络设备在发送该信令时,向不同覆盖等级的终端设备发送信令所采用的重复次数不同。例如,对于覆盖较远的终端设备,网络设备可以采用较多的重复次数发送信令,对于覆盖较近的终端设备,网络设备可以采用较少的重复次数发送信令。本申请中,可以是覆盖等级越大表示覆盖越远,对应的重复次数越多,也可以是覆盖等级越大表示覆盖越近,对应的重复次数越少,这里不做具体限定。6) Coverage level: When the network device sends the signaling, the number of repetitions used to send the signaling to terminal devices with different coverage levels is different. For example, for terminal devices with farther coverage, the network device can use a larger number of repetitions to send signaling, and for terminal devices with closer coverage, the network device can use a smaller number of repetitions to send signaling. In this application, a larger coverage level may mean that the coverage is further away, and the corresponding number of repetitions is greater. It may also be that a larger coverage level indicates that the coverage is closer, and the corresponding number of repetitions is smaller. There is no specific limitation here.
7)终端设备也可以称为终端。本申请实施例的终端设备还可以称为用户设备(user equipment,UE)等。终端可以广泛应用于各种场景,例如,物联网(internet of things,IOT)、设备到设备(device-to-device,D2D)、车物(vehicle to everything,V2X)通信、机器类通信(machine-type communication,MTC)、物联网(internet of things,IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。7) Terminal equipment can also be called terminal. The terminal equipment in the embodiment of this application may also be called user equipment (user equipment, UE), etc. Terminals can be widely used in various scenarios, such as Internet of things (IOT), device-to-device (D2D), vehicle to everything (V2X) communication, machine communication (machine -type communication (MTC), Internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. .

前文介绍了本申请实施例所涉及到的一些名词概念,下面介绍本申请实施例涉及的技术特征。The foregoing has introduced some terms and concepts involved in the embodiments of the present application, and the technical features involved in the embodiments of the present application will be introduced below.
标签支持微瓦级,或者百微瓦级的功耗,不能支持复杂的设计,因此标签的测量能力较弱,若将标签引入通信网络中,基站无法对标签进行功率控制,从而导致通信性能较差。Tags support microwatt level or hundreds of microwatt level power consumption and cannot support complex designs. Therefore, the tag's measurement capability is weak. If the tag is introduced into the communication network, the base station cannot control the power of the tag, resulting in poor communication performance. Difference.
例如,在通信网络中,基站通过如下方式对终端设备进行功率控制:基站发送系统消息,系统消息里包含目标接收功率,功率爬坡参数powerRampingStep。终端设备根据基站发送的指示信息,调整发射功率以满足基站配置的目标接收功率,并发送前导码(preamble)。若终端设备没有接收到基站针对preamble发送的随机接入响应,则调整发射功率:在之前发送功率上增加powerRampingStep,再次发送preamble。但是对于标签等测量能力较低的终端设备来讲,无法判断传输过程中损失的功率,因此无法确定如何调整发射功率才能满足读写器所指示的目标基接收功率。因此该方案不适合测量能力较低的终端设备。For example, in a communication network, the base station controls the power of the terminal device in the following way: the base station sends a system message, which contains the target received power and the power ramping parameter powerRampingStep. According to the instruction information sent by the base station, the terminal device adjusts the transmission power to meet the target reception power configured by the base station, and sends a preamble. If the terminal device does not receive the random access response sent by the base station for the preamble, it adjusts the transmission power: add powerRampingStep to the previous transmission power and send the preamble again. However, for terminal equipment with low measurement capabilities such as tags, it is impossible to determine the power lost during the transmission process, so it is impossible to determine how to adjust the transmit power to meet the target base received power indicated by the reader. Therefore, this solution is not suitable for terminal equipment with low measurement capabilities.
又例如,由于无法对标签进行功率控制,标签可能因为发送功率较低,导致读写器无法接收到该标签的随机接入消息。若标签随机接入失败,则需要在读写器配置一个新的参数Q后,标签基于该新的参数Q进行接入,导致该标签随机接入的时延较长。For another example, due to the inability to control the power of the tag, the tag may have low transmission power, causing the reader to be unable to receive the random access message of the tag. If the random access of the tag fails, the reader needs to be configured with a new parameter Q, and then the tag accesses based on the new parameter Q, resulting in a longer random access delay for the tag.
再例如,由于无法对标签进行功率控制,若标签支持上行频分发送数据,也就是,不同标签可以选择不同的频率进行接入,多个标签可以在同一时域资源的不同的频率上发送随机数(RN16)。同时发送数据的多个标签可能会出现干扰,导致读写器没有办法成功解码。For another example, since the power of the tag cannot be controlled, if the tag supports uplink frequency division to send data, that is, different tags can choose different frequencies for access, and multiple tags can send random signals on different frequencies of the same time domain resource. number (RN16). Multiple tags sending data at the same time may cause interference, causing the reader to be unable to successfully decode.

The embodiments of the present application can be applied to the scenarios shown in the above-mentioned Figures 2 to 6. For ease of description, the following describes the scenario shown in Figure 2, where the reader is a network device and the label is a terminal device. The terminal device may be a terminal device with weak measurement capabilities.
参见图7,为本申请提供的一种通信方法的流程示意图。该方法包括:Refer to Figure 7, which is a schematic flow chart of a communication method provided by this application. The method includes:
S701,网络设备向终端设备发送第一信令。相应的,终端设备接收来自网络设备的第一信令。S701. The network device sends the first signaling to the terminal device. Correspondingly, the terminal device receives the first signaling from the network device.
其中,第一信令包括终端设备的第一发送功率值或者第一发送功率范围,为了便于描述,下面以发送功率值为例进行说明。The first signaling includes a first transmission power value or a first transmission power range of the terminal device. For convenience of description, the following description takes the transmission power value as an example.
示例性的,第一信令为选择指令,或者,第一信令为寻呼指令,或者,第一信令为查询信令。目前,在通信网络中,网络设备通过系统消息向终端设备指示目标接收功率,接收到该系统消息的终端设备调整发射功率以满足网络设备配置的目标接收功率。而本申请通过选择指令/寻呼指令/查询指令指示发送功率值,可以使得该指令所选择(或者寻呼、或者触发)的终端设备调整发送功率值,而其他终端设备不调整发送功率值,从而可以实现分组调整。 For example, the first signaling is a selection instruction, or the first signaling is a paging instruction, or the first signaling is a query signaling. Currently, in the communication network, the network device indicates the target received power to the terminal device through a system message, and the terminal device that receives the system message adjusts the transmit power to meet the target received power configured by the network device. However, this application indicates the transmit power value through the selection command/paging command/query command, which can cause the terminal device selected (or paging, or triggered) by the command to adjust the transmit power value, while other terminal devices do not adjust the transmit power value. This enables group adjustment.
作为一个示例,第一信令指示的发送功率值可以是终端设备在随机接入过程中第一条信令或数据所使用的发射功率,例如,随机接入请求或者随机接入过程中的消息A或者随机接入消息中的消息3。这里的随机接入过程可以理解为终端设备与网络设备建立一种通信连接关系的过程,即完成这个流程后,终端设备与网络设备可以进行数据的传输。具体的,该第一条信令或者数据可以为随机接入前导码或者随机数。可选的,若终端设备接收到调整(或者更新)发射功率值的信令,则可以调整发送功率值后发送后续信令或数据,若终端设备未接收到调整(或者更新)发射功率值的信令,终端设备可以维持该第一信令指示的发射功率值进行发送数据。As an example, the transmit power value indicated by the first signaling may be the transmit power used by the terminal device for the first signaling or data in the random access process, for example, a random access request or a message in the random access process. A or message 3 in the random access message. The random access process here can be understood as the process of establishing a communication connection relationship between the terminal device and the network device. That is, after completing this process, the terminal device and the network device can transmit data. Specifically, the first piece of signaling or data may be a random access preamble or a random number. Optionally, if the terminal device receives a signaling to adjust (or update) the transmit power value, it can adjust the transmit power value and then send subsequent signaling or data. If the terminal device does not receive a signal to adjust (or update) the transmit power value, signaling, the terminal device can maintain the transmit power value indicated by the first signaling to send data.
一种可能的实现方式中,第一信令包括一个或多个覆盖等级对应的发送功率值,其中,该一个或多个覆盖等级包括上述终端设备对应的覆盖等级。举例说明,假设上述终端设备对应的覆盖等级为第一覆盖等级,第一信令可以包括第一覆盖等级对应的第一发送功率值。可选的,第一信令还可以包括第二覆盖等级对应的第二发送功率值、第三覆盖等级对应的发送功率值等。本申请不限定第一信令所指示的覆盖等级的数量。In a possible implementation, the first signaling includes transmit power values corresponding to one or more coverage levels, where the one or more coverage levels include coverage levels corresponding to the above-mentioned terminal equipment. For example, assuming that the coverage level corresponding to the above-mentioned terminal device is the first coverage level, the first signaling may include a first transmission power value corresponding to the first coverage level. Optionally, the first signaling may also include a second transmission power value corresponding to the second coverage level, a transmission power value corresponding to the third coverage level, etc. This application does not limit the number of coverage levels indicated by the first signaling.
作为一个示例,第一信令可以用于调整其他待接入的终端设备(例如在上述终端设备之后接入的终端设备)的发送功率,也就是第一信令适用于其他待接入的终端设备。或者,第一信令也可以用于调整上述终端设备和其他待接入的终端设备(例如在上述终端设备之后接入的终端设备)的发送功率,也就是第一信令适用于上述终端设备和其他待接入的终端设备。或者,第一信令也可以用于调整上述终端设备的发射功率,也就是第一信令适用于上述终端设备。As an example, the first signaling can be used to adjust the transmission power of other terminal devices to be accessed (for example, terminal devices to be accessed after the above-mentioned terminal device), that is, the first signaling is applicable to other terminal devices to be accessed. equipment. Alternatively, the first signaling can also be used to adjust the transmission power of the above-mentioned terminal device and other terminal devices to be accessed (for example, a terminal device accessed after the above-mentioned terminal device), that is, the first signaling is applicable to the above-mentioned terminal device. and other terminal devices to be accessed. Alternatively, the first signaling may also be used to adjust the transmit power of the above-mentioned terminal device, that is, the first signaling is applicable to the above-mentioned terminal device.
可选的,在上述实现方式中,终端设备可以预先获取自身的覆盖等级,例如,预先配置覆盖等级,或者,通过在第一信令之前接收的信令的重复次数确定自身的覆盖等级,或者,也可以通过测量判断覆盖等级等等。终端设备也可以通过其他方式获取自身的覆盖等级,这里不做具体限定。Optionally, in the above implementation manner, the terminal device can obtain its own coverage level in advance, for example, pre-configure the coverage level, or determine its own coverage level by the number of repetitions of signaling received before the first signaling, or , you can also judge the coverage level and so on through measurement. The terminal device can also obtain its own coverage level through other methods, which are not specifically limited here.
另一种可能的实现方式中,第一信令是以第一重复次数发送的,第一发送功率值对应于第一重复次数。其中,重复次数可以包括如下至少一项:比特重复的次数、符号重复的次数、码块重复的次数、信息重复的次数等。In another possible implementation, the first signaling is sent with a first number of repetitions, and the first transmission power value corresponds to the first number of repetitions. The number of repetitions may include at least one of the following: the number of bit repetitions, the number of symbol repetitions, the number of code block repetitions, the number of information repetitions, etc.
一种示例性说明中,若第一信令对应的重复次数越多,所包括的发送功率越大。可以理解为,若第一信令对应重复次数1时指示发送功率值1,第一信令对应重复次数2时指示发送功率值2,若重复次数1大于重复次数2,则发送功率值1大于发送功率值2。In an exemplary description, if the number of repetitions corresponding to the first signaling is greater, the included transmission power is greater. It can be understood that if the first signaling corresponds to the repetition number 1, it indicates the transmission power value 1, and when the first signaling corresponds to the repetition number 2, it indicates the transmission power value 2. If the repetition number 1 is greater than the repetition number 2, the transmission power value 1 is greater than Transmit power value 2.
另一种可能的实现方式中,第一信令是以第一覆盖等级配置发送的,第一发送功率值对应于第一覆盖等级。In another possible implementation, the first signaling is sent in a first coverage level configuration, and the first transmission power value corresponds to the first coverage level.
一种示例性说明中,假设覆盖等级越小表示终端设备与网络设备之间的通信性能越好或者表示终端设备与网络设备之间的距离越近。若第一信令对应的覆盖等级越大,所包括的发送功率越大。可以理解为,若第一信令对应覆盖等级1时指示发送功率值3,第一信令对应覆盖等级2时指示发送功率值4,若覆盖等级1大于覆盖等级2,则发送功率值3大于发送功率值4。In an exemplary explanation, it is assumed that the smaller the coverage level, the better the communication performance between the terminal device and the network device, or the closer the distance between the terminal device and the network device. If the coverage level corresponding to the first signaling is larger, the included transmission power is larger. It can be understood that if the first signaling corresponds to coverage level 1, it indicates a transmit power value of 3, and if the first signaling corresponds to coverage level 2, it indicates a transmit power value of 4. If coverage level 1 is greater than coverage level 2, then the transmit power value 3 is greater than Transmit power value 4.
S702,终端设备以第一发送功率值向网络设备发送第二信令。相应的,网络设备接收来自终端设备的第二信令。S702: The terminal device sends the second signaling to the network device with the first transmission power value. Correspondingly, the network device receives the second signaling from the terminal device.
示例性的,第二信令可以是随机接入请求或者随机接入过程中的消息A或者随机接入过程中的消息3。举例说明,第二信令可以包括随机数和/或前导码,或者,第二信令可以为随机接入前导码。其中,随机数可以是RN16等。For example, the second signaling may be a random access request or message A in the random access process or message 3 in the random access process. For example, the second signaling may include a random number and/or a preamble, or the second signaling may be a random access preamble. Among them, the random number can be RN16, etc.
或者,第二信令也可以是用于传输上行数据的消息,具体的,第二信令可以包括上行数据和前导码。Alternatively, the second signaling may also be a message used to transmit uplink data. Specifically, the second signaling may include the uplink data and a preamble.
可选的,若网络设备成功接收到第二信令,则网络设备可以向终端设备发送响应消息。如图8所示。一种可选的方案中,终端设备在接收到响应消息后可以发送上行数据。Optionally, if the network device successfully receives the second signaling, the network device may send a response message to the terminal device. As shown in Figure 8. In an optional solution, the terminal device can send uplink data after receiving the response message.
可选的,若网络设备未成功接收到第二信令,例如,网络设备只检测到第二信令中的前导码,具体的,可以是只检测到和随机数(或者上行数据)一起发送的前导码;或者,网络设备检测到第二信令的发送功率较低,例如,网络设备检测到前导码的功率小于门限值,其中,该前导码可以是和随机数(或者上行数据)一起发送的前导码,也可以是随机接入前导码。网络设备可以向终端设备发送第三信令,第三信令指示终端设备调整发送功率为第三发送功率值。Optionally, if the network device fails to receive the second signaling successfully, for example, the network device only detects the preamble in the second signaling. Specifically, it may only detect the preamble sent together with the random number (or uplink data). preamble; or, the network device detects that the transmission power of the second signaling is low, for example, the network device detects that the power of the preamble is less than the threshold value, where the preamble can be and random number (or uplink data) The preamble sent together can also be a random access preamble. The network device may send third signaling to the terminal device, and the third signaling instructs the terminal device to adjust the transmit power to the third transmit power value.
可选的,终端设备在接收第三信令之后可以以第三发送功率值再次(或者重新)发送第二信令。如图9所示。Optionally, after receiving the third signaling, the terminal device may send the second signaling again (or re) with the third transmission power value. As shown in Figure 9.
终端设备还可以以第三发送功率值向网络设备发送第四信令。其中,第三发送功率值可以是第三信 令包括的,例如,第三信令中可以包括第三发送功率值。或者,第三发送功率值也可以是终端设备根据第三信令确定的,例如,第三信令包括第三发送功率值与第一发送功率值之间的差值,终端设备可以根据第一发送功率值和该差值确定第三发送功率值;又例如,第三信令仅指示提升发送功率值,由终端设备确定提升后的发送功率值为第三发送功率值,在该方式中,终端设备提升的幅值可以是终端设备确定的,也可以是协议规定的,也可以是预先配置的,这里不做具体限定。The terminal device may also send fourth signaling to the network device with a third transmission power value. Wherein, the third transmit power value may be a third signal For example, the third signaling may include a third transmission power value. Alternatively, the third transmit power value may also be determined by the terminal device based on the third signaling. For example, the third signaling includes the difference between the third transmit power value and the first transmit power value. The terminal device may determine the third transmit power value based on the first transmit power value. The transmit power value and the difference determine the third transmit power value; for another example, the third signaling only indicates to increase the transmit power value, and the terminal device determines that the increased transmit power value is the third transmit power value. In this method, The amplitude of the improvement of the terminal device may be determined by the terminal device, may be specified by the protocol, or may be pre-configured, and is not specifically limited here.
一种可能的实施方式中,第三信令还可以指示第一覆盖等级对应的发送功率调整为第三发送功率值。或者,第三信令指示第一覆盖等级的终端设备将发送功率调整为第三发送功率值。In a possible implementation, the third signaling may also indicate that the transmission power corresponding to the first coverage level is adjusted to the third transmission power value. Alternatively, the third signaling instructs the terminal device of the first coverage level to adjust the transmission power to the third transmission power value.
作为一种示例性描述,本申请中“调整发送功率值”也可以描述为“更新发送功率值”或者“提升发送功率值”等等。As an exemplary description, "adjusting the transmission power value" in this application can also be described as "updating the transmission power value" or "increasing the transmission power value" and so on.
示例性的,第三信令可以是Query信令,也可以是QueryRep信令,还可以是配置信令。For example, the third signaling may be Query signaling, QueryRep signaling, or configuration signaling.
在一种可能的实施方式中,上述第一信令和/或第三信令可以适用于第一类终端设备,例如,第一信令和/或第三信令可以适用于测量能力较弱的终端设备,例如,无源标签、半无源标签或主动生成载波标签等。当然,上述第一信令和/或第三信令也可以适用于其他类型的终端设备,这里不再一一列举。可选的,第一信令和/或第三信令适用的终端设备类型可以在第一信令和/或第三信令中通过隐式或显式的方式进行指示,也可以通过其他信令进行指示,这里不做具体限定。In a possible implementation, the above-mentioned first signaling and/or third signaling may be applicable to the first type of terminal equipment. For example, the first signaling and/or the third signaling may be applicable to terminal devices with weak measurement capabilities. Terminal equipment, such as passive tags, semi-passive tags or actively generated carrier tags, etc. Of course, the above-mentioned first signaling and/or third signaling may also be applicable to other types of terminal equipment, and will not be listed one by one here. Optionally, the type of terminal equipment to which the first signaling and/or the third signaling is applicable may be indicated implicitly or explicitly in the first signaling and/or the third signaling, or may be indicated through other signaling. Orders are given for instructions, and there are no specific limitations here.
可选的,上述通过第三信令调整发送功率值的方案的一种并列方案可以为:当终端设备随机接入失败的次数大于或等于N时,提升发送功率值并再次发起随机接入。其中,N为大于0的整数。Optionally, a parallel solution to the above solution of adjusting the transmit power value through third signaling may be: when the number of random access failures of the terminal device is greater than or equal to N, the transmit power value is increased and random access is initiated again. Among them, N is an integer greater than 0.
一种具体的方案中,若终端设备随机接入失败的次数小于M,终端设备可以在原来发送功率值的基础上增加第一值并再次发起随机接入。若终端设备随机接入失败的次数大于或等于M,终端设备可以在原来发送功率值的基础上增加第二值并再次发起随机接入,其中,M为大于N的整数,第二值可以大于第一值。In a specific solution, if the number of random access failures of the terminal device is less than M, the terminal device can increase the first value based on the original transmission power value and initiate random access again. If the number of random access failures of the terminal device is greater than or equal to M, the terminal device can increase the second value based on the original transmission power value and initiate random access again, where M is an integer greater than N, and the second value can be greater than first value.
本申请实施例中通过指示具体的发送功率值,相比于指示目标接收功率,可以简化功率控制流程,使得基站可以实现对测量能力弱的终端设备的功率控制。并且,本申请实施例中网络设备可以根据不同的覆盖等级指示对应的发送功率值,可以实现更精确的功率控制。In the embodiment of the present application, by indicating a specific transmit power value, compared with indicating the target received power, the power control process can be simplified, so that the base station can implement power control for terminal equipment with weak measurement capabilities. Moreover, in this embodiment of the present application, the network device can indicate corresponding transmission power values according to different coverage levels, thereby achieving more precise power control.
以上介绍了一种实现网络设备对终端设备进行功率控制的方法,该方法在随机接入之前通过选择信令、寻呼信令、查询信令等指示发送功率值,使得终端设备可以根据指示的发送功率值发起随机接入,实现网络设备对终端设备的功率控制。下面介绍另一种方法,该方法在随机接入过程中调整终端设备的发送功率值,一方面可以实现网络设备对终端设备的功率控制,另一方面还可以降低终端设备的随机接入时延。The above introduces a method for network equipment to control the power of terminal equipment. This method sends power values through selection signaling, paging signaling, query signaling and other instructions before random access, so that the terminal equipment can follow the instructions. The sending power value initiates random access and realizes the power control of the network device on the terminal device. Another method is introduced below. This method adjusts the transmit power value of the terminal device during the random access process. On the one hand, it can realize the power control of the terminal device by the network device. On the other hand, it can also reduce the random access delay of the terminal device. .

The second power; for another example, the second signaling only instructs to increase the transmit power, and the terminal device determines that the increased transmit power is the second power. In this method, the amplitude of the increase by the terminal device can be determined by the terminal device, or It can be specified in the agreement or pre-configured.

In addition, when the network device determines that the terminal device's transmission power is low and cannot successfully decode, it can instruct the terminal device to reconnect, so that the terminal device does not have to wait for other terminal devices to complete the access before trying to access, thereby reducing the terminal device's random access delay.

For example, the network device can instruct the terminal device to increase the transmit power by a numerical value.
