技术领域Technical Field
本申请属于通信技术领域，具体涉及一种传输方法、装置、网络侧设备及终端。The present application belongs to the field of communication technology, and specifically relates to a transmission method, device, network-side equipment and terminal.
背景技术Background technique
目前，为了减少终端在待机状态下的接收活动，使得射频(Radio Frequency，RF)和基带(MODEM)模块真正的关闭从而大大降低通信接收的功耗，可以通过在终端的接收模块中引入了一个近“零”功率的接收机从而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理，只靠被动的匹配滤波和较小功耗的信号处理。在基站侧，通过按需(on-demand)触发唤醒信号，就可以激活近“零”功率的接收机获知激活的通告，从而触发终端内部的一系列流程，例如，打开射频收发以及基带处理等模块。At present, in order to reduce the receiving activity of the terminal in the standby state, the RF (Radio Frequency, RF) and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, and only relies on passive matching filtering and signal processing with low power consumption. On the base station side, by triggering the wake-up signal on demand (on-demand), the near "zero" power receiver can be activated to obtain the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.
然而，如何灵活地选择信号的传输格式，使得网络在资源开销和覆盖性能之间做更好的折中已成为亟待解决的问题。However, how to flexibly select the signal transmission format so that the network can make a better compromise between resource overhead and coverage performance has become an urgent problem to be solved.

为了方便理解，以下对本申请实施例涉及的一些内容进行说明：For ease of understanding, some contents involved in the embodiments of the present application are described below:
一、低功耗接收机1. Low power receiver
低功耗接收机，即低功耗唤醒接收机(Low Power Wake up Receiver，LP-WUR)或称为近零功耗接收机(Almost Zero Power Wake Up Receiver,AZP-WUR)。其基本工作原理为接收端包含第一模块和第二模块，具体如图2所示，第一模块为主通信模块，用于移动通信数据的收发，第二模块为低功耗接收模块(也称低功耗唤醒接收模块)，用于接收唤醒信号，也称为低功耗唤醒信号(Low Power Wake Up Signal，LP-WUS)。终端在节能状态下开启低功耗接收模块来监听LP-WUS且关闭主通信模块。当有下行数据到达时，网络侧设备会发送唤醒信号给终端，终端通过低功耗接收模块监听到唤醒信号后通过一系列的判断后触发主通信模块从关闭到开启，而此时低功耗接收模块从工作态进入关闭状态(也称睡眠状态)。低功耗唤醒接收模块可以连续开启，或间歇性开启，在开启时可接收低功耗唤醒信号。Low-power receiver, namely Low-Power Wake-up Receiver (LP-WUR) or Almost-Zero-Power Wake-Up Receiver (AZP-WUR). Its basic working principle is that the receiving end includes a first module and a second module, as shown in FIG2. The first module is a main communication module for receiving and sending mobile communication data, and the second module is a low-power receiving module (also called a low-power wake-up receiving module) for receiving a wake-up signal, also called a low-power wake-up signal (LP-WUS). The terminal turns on the low-power receiving module in the energy-saving state to monitor LP-WUS and turns off the main communication module. When downlink data arrives, the network-side device sends a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments. At this time, the low-power receiving module enters the off state (also called the sleep state) from the working state. The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive the low-power wake-up signal when it is turned on.
二、低功耗唤醒信号2. Low power wake-up signal
为了减少终端在待机状态下的接收活动，使得射频(Radio Frequency，RF)和基带(MODEM)模块真正的关闭从而大大降低通信接收的功耗，可以通过在终端的接收模块中引入了一个近“零”功率的接收机从而实现。这个近“零”功率的接收机不需要复杂的RF模块的信号检测(如放大、滤波、量化等等)和MODEM的信号处理，只靠被动的匹配 滤波和较小功耗的信号处理。In order to reduce the receiving activity of the terminal in the standby state, the RF and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, and only relies on passive matching. Filtering and signal processing with low power consumption.
在基站侧，通过按需(on-demand)触发唤醒信号，就可以激活近“零”功率的接收机获知激活的通告，从而触发终端内部的一系列流程，例如，打开射频收发以及基带处理等模块。On the base station side, by triggering a wake-up signal on demand, the near-zero power receiver can be activated to receive the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.
这种唤醒信号通常来说是一些比较简单的开关键控信号(on-off keying)，那样接收机就可以通过简单的能量检测，以及之后的可能的序列检测识别等过程获知唤醒通告。此外，在终端开启低功耗唤醒接收机来接收唤醒信号的同时，主接收机模块可以维持在一个较低耗电水平下工作，从而通过接收唤醒信号来实现功耗节省。This wake-up signal is usually some simple on-off keying signal, so that the receiver can be informed of the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition. In addition, while the terminal turns on the low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thereby achieving power saving by receiving the wake-up signal.
三、反向散射通信(Backscatter Communication，BSC)，或，被动的物联网(passive IoT)通信3. Backscatter Communication (BSC), or passive IoT communication
反向散射通信是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输自己信息。Backscatter communication refers to the backscatter communication device using the radio frequency signals from other devices or the environment to modulate the signal to transmit its own information.
反向散射通信设备，可以是：Backscatter communication equipment, which can be:
(1)传统射频识别(Radio Frequency Identification，RFID)中的反向散射通信设备，一般是一个标签(Tag)，属于无源IoT设备(Passive-IoT)；(1) The backscatter communication device in traditional radio frequency identification (RFID) is generally a tag, which belongs to passive IoT devices (Passive-IoT);
(2)半无源(semi-passive)的tag，这类tag的下行接收或者上行反射具备一定的放大能力；(2) Semi-passive tags, which have a certain amplification capability in downlink reception or uplink reflection;
(3)具备主动发送能力的tag(active tag)，这类终端可以不依赖对入射信号的反射向基站(gNB)或阅读器(reader)发送信息。(3) Tags with active sending capabilities. This type of terminal can send information to the base station (gNB) or reader without relying on the reflection of the incident signal.
一种简单的实现方式为，tag需要发送“1”时，tag对入射载波信号进行反射，tag需要发送“0”时不进行反射。A simple implementation method is that when the tag needs to send "1", the tag reflects the incident carrier signal, and when the tag needs to send "0", it does not reflect.
反向散射通信设备通过调节其内部阻抗来控制电路的反射系数Γ，从而改变入射信号的幅度、频率、相位等，实现信号的调制。其中信号的反射系数可表征为：
Backscatter communication equipment controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The reflection coefficient of the signal can be characterized as:
其中，Z0为天线特性阻抗，Z1是负载阻抗。假设入射信号为Sin(t)，则输出信号为因此，通过合理的控制反射系数可实现对应的幅度调制、频率调制或相位调制。Where Z0 is the antenna characteristic impedance and Z1 is the load impedance. Assuming the incident signal is S in (t), the output signal is Therefore, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved by properly controlling the reflection coefficient.
可选地，本申请实施例中所述标签设备为上述反向散射通信设备。Optionally, the tag device described in the embodiment of the present application is the above-mentioned backscatter communication device.
可选地，本申请实施例中，第一传输可以是反向散射通信中的相关传输。Optionally, in the embodiment of the present application, the first transmission may be a related transmission in backscatter communication.
本实施例中，反向散射通信包括以下内容的传输：In this embodiment, backscatter communication includes transmission of the following contents:
(1)激励载波(carrier wave，CW)传输，也就是载波信号的传输；一种实施例中，该激励载波可以是由网络侧设备发送给标签(tag)的，还可以是由终端发送给标签的。(1) Excitation carrier wave (CW) transmission, that is, the transmission of a carrier signal; in one embodiment, the excitation carrier wave can be sent from a network-side device to a tag, or can be sent from a terminal to a tag.
(2)控制命令(command)的传输，例如：选取命令、查询命令、重复查询命令、答复命令、读取命令、写入命令、随机请求命令等；一种实施例中，该控制命令可以是由网络侧设备发送给标签(tag)的，还可以是由终端发送给标签的。 (2) Transmission of control commands, such as selection commands, query commands, repeated query commands, reply commands, read commands, write commands, random request commands, etc. In one embodiment, the control command can be sent from a network-side device to a tag, or from a terminal to a tag.
可选地，所述控制命令可以包括以下至少一项：选择类型命令，查询类型命令，接入命令；其中，所述选择类型命令包括以下至少一项：选择命令(一个具体的选择命令)，盘点命令，排序命令；所述查询类型命令包括以下至少一项：查询命令(一个具体的查询命令)，调节查询命令，重复查询命令；所述接入命令包括以下至少一项：随机请求命令，读取命令，写入命令，销毁命令，锁定命令，访问命令，安全相关接入命令，文件管理相关接入命令。Optionally, the control command may include at least one of the following: a selection type command, a query type command, and an access command; wherein the selection type command includes at least one of the following: a selection command (a specific selection command), an inventory command, and a sorting command; the query type command includes at least one of the following: a query command (a specific query command), an adjustment query command, and a repeat query command; the access command includes at least one of the following: a random request command, a read command, a write command, a destroy command, a lock command, an access command, a security-related access command, and a file management-related access command.
选择类型(Select)命令是必备的，由于标签有多种属性，基于用户设定的标准和策略，使用选择类型命令，改变某些属性和标志就人为选择或圈定了一个特定的标签群，可以只对它们进行盘点识别或存取操作，这样有利于减少冲突和重复识别，加快识别速度。The Select command is essential. Since tags have multiple attributes, based on the standards and policies set by the user, the Select command can be used to change certain attributes and flags to artificially select or circle a specific group of tags. Only inventory recognition or access operations can be performed on them. This helps reduce conflicts and repeated recognition and speed up recognition.
盘点阶段的命令用于开始一次盘点。例如，查询命令用于启动一轮盘点，并决定哪些标记参与该轮盘点；调节查询命令用于将标签原来接收时刻(Slot)的数目进行调整；重复查询命令用于减少标签Slot的数字。The commands in the inventory phase are used to start an inventory. For example, the query command is used to start a round of inventory and determine which tags participate in the round; the adjustment query command is used to adjust the number of the tag's original receiving time (Slot); the repeat query command is used to reduce the number of the tag's Slot.
接入命令(Access)中，随机请求(Req_RN)命令要求标签产生一个随机数；读取命令用于从标签的存储中的某个位置读取资料；写入命令用于写入资料到标签的存储中；销毁命令可以隐私的泄漏，标签无法再使用；锁定命令用于标签不能再进行写入的动作，防止资料被任意的串改；访问命令用于当标签拥有密码时候让标签从开启(Open)的状态转成保护(Secure)状态；安全相关接入命令用于保障标签安全；文件管理相关接入命令可以用于对标签内文件进行管理。In the access command (Access), the random request (Req_RN) command requires the tag to generate a random number; the read command is used to read data from a certain location in the tag's storage; the write command is used to write data to the tag's storage; the destroy command can leak privacy and the tag can no longer be used; the lock command is used to prevent the tag from being written to and prevent the data from being arbitrarily tampered with; the access command is used to change the tag from an open state to a secure state when the tag has a password; security-related access commands are used to ensure tag security; file management-related access commands can be used to manage files in the tag.
(3)反馈信息传输，在反向散射通信中，也可以理解为反向散射信息的传输，包括，例如：Tag标识信息(如查询过程中的临时代表Tag身份的16-bit随机数)、电子产品代码信息、Tag状态信息等)。一种实施例中，该反向散射信道或信号可以是标签通过反向散射发送给终端的，还可以是标签通过反向散射发送给网络侧设备的。(3) Feedback information transmission, in backscatter communication, can also be understood as the transmission of backscatter information, including, for example: tag identification information (such as a 16-bit random number temporarily representing the tag identity during the query process), electronic product code information, tag status information, etc.). In one embodiment, the backscatter channel or signal can be sent by the tag to the terminal through backscattering, or it can be sent by the tag to the network side device through backscattering.

b、盘点(Inventory)操作b. Inventory operation
读取器识别标签的过程。读取器通过在四个会话中的一个会话中发送查询命令来开始盘点循环。一个或多个标签可能回复。读取器检测单个标签应答，并请求协议控制(Protocol Control，PC)，可选的请求扩展协议控制(Extended Protocol Control，XPC)字、电子产品代码(Electronic Product Code，EPC)和循环冗余校验16(Cyclic Redundancy Check，CRC-16)。盘点中包含多个命令。其中，非常重要的命令为质询命令。具体参见下表2。The process by which a reader identifies a tag. The reader starts the inventory cycle by sending a query command in one of four sessions. One or more tags may reply. The reader detects a single tag reply and requests a Protocol Control (PC), optionally an Extended Protocol Control (XPC) word, an Electronic Product Code (EPC), and a Cyclic Redundancy Check 16 (CRC-16).

现在超高频射频识别(UHF RFID)的协议设计中，在盘点模式下，要求读取器发送查询指令(Query)后标签(Tag)响应回应(Reply)，即产生一个16-bit的随机数给读取器。然后读取器将该序列通过ACK指令发给Tag后，Tag将相关的数据发送给阅读器。In the current UHF RFID protocol design, in inventory mode, the reader is required to send a query command (Query) and the tag (Tag) responds (Reply), that is, generates a 16-bit random number to the reader. Then the reader sends the sequence to the tag through the ACK command, and the tag sends the relevant data to the reader.
可选地，上述读取器或阅读器可以为本实施例中的设备。Optionally, the reader or reader mentioned above may be the device in this embodiment.
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的传输方法进行详细地说明。The transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.
如图3所示，本申请实施例的一种传输方法，包括：As shown in FIG3 , a transmission method according to an embodiment of the present application includes:
步骤301，网络侧设备发送第一格式的第一信号。Step 301: A network-side device sends a first signal in a first format.
本步骤中，网络侧设备向终端发送第一格式的唤醒信号和/或反向散射通信相关的控 制命令。其中，反向散射通信相关的控制命令可以是用于触发反向散射通信、配置反向散射通信等。In this step, the network side device sends a wake-up signal in a first format and/or a control signal related to backscatter communication to the terminal. Among them, the control command related to backscatter communication can be used to trigger backscatter communication, configure backscatter communication, etc.
步骤302，所述网络侧设备在满足第一条件的情况下，发送第二格式的第一信号；Step 302: the network side device sends a first signal in a second format when a first condition is met;
所述第一条件包括以下至少一项：The first condition includes at least one of the following:
接收到第一信息，所述第一信息为对所述第一格式的第一信号的接收反馈信息；receiving first information, where the first information is reception feedback information of a first signal in the first format;
未接收到第二信息，所述第二信息为通过所述第一格式的第一信号唤醒的终端的相关信息；not receiving second information, where the second information is relevant information of the terminal awakened by the first signal in the first format;
所述第一格式的第一信号的测量值满足第一门限；A measurement value of the first signal in the first format satisfies a first threshold;
所述第一格式的第一信号的测量值满足所述第一门限的次数大于或等于第一次数；The number of times that the measured value of the first signal in the first format satisfies the first threshold is greater than or equal to a first number;
所述第一格式的第一信号的测量值满足所述第一门限的持续时间大于或等于第一时长；The duration for which the measured value of the first signal in the first format meets the first threshold is greater than or equal to a first duration;
确定终端未接收到或错误接收到所述第一格式的第一信号；Determining that the terminal has not received or has erroneously received the first signal in the first format;
确定终端未接收到或错误接收到所述第一格式的第一信号的次数大于或等于第二次数；Determine that the number of times that the terminal fails to receive or incorrectly receives the first signal in the first format is greater than or equal to a second number;
确定终端未接收到或错误接收到所述第一格式的第一信号的持续时间大于或等于第二时长；Determine that a duration during which the terminal fails to receive or erroneously receives the first signal in the first format is greater than or equal to a second duration;
其中，所述第一信号包括以下至少一项：唤醒信号，反向散射通信相关的控制命令。The first signal includes at least one of the following: a wake-up signal, a control command related to backscatter communication.
本步骤中，网络侧设备在步骤301发送第一格式的第一信号之后，还将基于上述的第一条件，在满足该第一条件的情况下，再次发送第二格式的第一信号。In this step, after sending the first signal in the first format in step 301, the network side device will also send the first signal in the second format again based on the above-mentioned first condition when the first condition is met.
如此，按照上述步骤301和302，网络侧设备能够在发送第一格式的第一信号之后，进一步基于如上所述的第一条件，在满足该第一条件的情况下，再次发送第二格式的第一信号，从而实现了按照条件灵活选择第一信号格式的目的，能够在资源开销和覆盖性能之间做更好的折中。In this way, according to the above steps 301 and 302, the network side device can, after sending the first signal in the first format, further send the first signal in the second format again based on the first condition as described above, when the first condition is met, thereby achieving the purpose of flexibly selecting the first signal format according to the condition and making a better compromise between resource overhead and coverage performance.
其中，网络侧设备发送第一格式的第一信号，包括：The network side device sends a first signal in a first format, including:
网络侧设备发送至少一次第一格式的第一信号。The network side device sends a first signal in a first format at least once.
也就是说，在满足第一条件之前，网络侧设备发送M次第一格式的第一信号，M为大于或等于1的正整数。That is, before the first condition is met, the network side device sends the first signal in the first format M times, where M is a positive integer greater than or equal to 1.
该实施例中，第一格式的第一信号的测量值是对应一个或多个测量量的测量值。具体的测量量包括但不限于参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)。In this embodiment, the measurement value of the first signal in the first format is a measurement value corresponding to one or more measurement quantities. Specific measurement quantities include but are not limited to Reference Signal Receiving Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).
而测量值满足第一门限，可以是测量值低于第一门限，也可以是测量值高于第一门限。即，第一格式和第二格式的覆盖性能的好坏不限，也就是说不限于第一格式的覆盖性能一定比第二格式的覆盖性能差。The measured value satisfies the first threshold, which means that the measured value is lower than the first threshold or higher than the first threshold. That is, the coverage performance of the first format and the second format is not limited, that is, the coverage performance of the first format is not necessarily worse than the coverage performance of the second format.
作为一种实施方式，网络侧设备发送的第二格式的第一信号的覆盖性较发送的第一格 式的第一信号的覆盖性能更佳。As an implementation manner, the coverage of the first signal in the second format sent by the network side device is greater than that of the first format sent. The coverage performance of the first signal of the formula is better.
需要说明的是，第一门限、第一次数、第一时长、第二次数、第二时长可以由预先定义或网络侧设备配置。It should be noted that the first threshold, the first number, the first duration, the second number, and the second duration may be predefined or configured by a network-side device.
可选地，该实施例中，所述唤醒信号为低功耗唤醒信号。Optionally, in this embodiment, the wake-up signal is a low-power wake-up signal.
可选地，该实施例中，所述第一信息包括以下至少一项：Optionally, in this embodiment, the first information includes at least one of the following:
第一反馈信息，所述第一反馈信息用于指示所述终端未接收到或错误接收到所述第一格式的第一信号；first feedback information, where the first feedback information is used to indicate that the terminal has not received or has erroneously received the first signal in the first format;
第二反馈信息，所述第二反馈信息用于指示所述第一格式的第一信号的测量值满足第一门限；second feedback information, where the second feedback information is used to indicate that a measurement value of the first signal in the first format satisfies a first threshold;
第三反馈信息，所述第三反馈信息用于指示所述网络侧设备更换所述唤醒信号的格式；third feedback information, where the third feedback information is used to instruct the network side device to change the format of the wake-up signal;
第四反馈信息，所述第四反馈信息用于指示所述第一格式的第一信号的测量值满足所述第一门限的次数大于或等于第一次数；fourth feedback information, where the fourth feedback information is used to indicate that the number of times that the measured value of the first signal in the first format satisfies the first threshold is greater than or equal to a first number;
第五反馈信息，所述第五反馈信息用于指示所述第一格式的第一信号的测量值满足所述第一门限的持续时间大于或等于第一时长；fifth feedback information, where the fifth feedback information is used to indicate that the duration for which the measured value of the first signal in the first format meets the first threshold is greater than or equal to a first duration;
第六反馈信息，所述第六反馈信息用于指示所述终端未接收到或错误接收到所述第一格式的第一信号的次数大于或等于第二次数；Sixth feedback information, where the sixth feedback information is used to indicate that the number of times that the terminal has not received or erroneously received the first signal in the first format is greater than or equal to a second number;
第七反馈信息，所述第七反馈信息用于指示所述终端未接收到或错误接收到所述第一格式的唤醒信号的持续时间大于或等于第二时长。The seventh feedback information is used to indicate that the duration that the terminal fails to receive or erroneously receives the wake-up signal in the first format is greater than or equal to a second duration.
即，终端针对第一格式的第一信号的接收进行反馈，反馈的第一信息包括上所述的第一反馈信息、第二反馈信息、第三反馈信息、第四反馈信息、第五反馈信息、第六反馈信息、第七反馈信息中的至少一项，以便网络侧设备接收到第一信息的情况下，发送第二格式的第一信号。That is, the terminal provides feedback on the reception of the first signal in the first format, and the first feedback information includes at least one of the first feedback information, the second feedback information, the third feedback information, the fourth feedback information, the fifth feedback information, the sixth feedback information, and the seventh feedback information mentioned above, so that when the network side device receives the first information, it sends the first signal in the second format.
可选地，所述第一信息通过物理上行信道承载。Optionally, the first information is carried via a physical uplink channel.
这里，物理上行信道包括物理上行控制信道(Physical Uplink Control CHannel，PUCCH)，和/或，物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)。例如，第一信息通过上行控制信息(Uplink Control Information,UCI)承载。Here, the physical uplink channel includes a physical uplink control channel (Physical Uplink Control CHannel, PUCCH) and/or a physical uplink shared channel (Physical Uplink Shared CHannel, PUSCH). For example, the first information is carried by uplink control information (Uplink Control Information, UCI).
另外，若第一条件包括第一格式的第一信号的测量值满足第一门限，所述第一格式的第一信号的测量值满足所述第一门限的次数大于或等于第一次数，所述第一格式的第一信号的测量值满足所述第一门限的持续时间大于或等于第一时长，终端未接收到或错误接收到所述第一格式的第一信号，终端未接收到或错误接收到所述第一格式的第一信号的次数大于或等于第二次数，终端未接收到或错误接收到所述第一格式的第一信号的持续时间大于或等于第二时长中的至少一项，网络侧设备可以在接收到第一信息后，能够基于该第一信息确定第一条件是否满足。当然，网络侧设备也可直接测量第一格式的第一信号，基于测量结果确定第一条件是否满足，在此不再赘述。In addition, if the first condition includes at least one of the following: the measured value of the first signal in the first format satisfies the first threshold, the number of times the measured value of the first signal in the first format satisfies the first threshold is greater than or equal to the first number, the duration for which the measured value of the first signal in the first format satisfies the first threshold is greater than or equal to the first duration, the terminal does not receive or erroneously receives the first signal in the first format, the number of times the terminal does not receive or erroneously receives the first signal in the first format is greater than or equal to the second number, and the duration for which the terminal does not receive or erroneously receives the first signal in the first format is greater than or equal to the second duration, the network side device can determine whether the first condition is met based on the first information after receiving the first information. Of course, the network side device can also directly measure the first signal in the first format and determine whether the first condition is met based on the measurement result, which will not be repeated here.
应该知道的是，终端接收第一格式的第一信号，由于该第一信号会唤醒终端执行相关 操作，终端就能够向网络侧设备发送第二信息。考虑到第一格式的第一信号的失效，第一条件包括未接收到第二信息，这样，在未接收到第二信息的情况下，发送第二格式的第一信号。It should be known that the terminal receives the first signal in the first format, and since the first signal wakes up the terminal to execute the related The terminal can send the second information to the network side device by operating the first signal in the first format. Considering the failure of the first signal in the first format, the first condition includes not receiving the second information. Thus, the first signal in the second format is sent when the second information is not received.
可选地，所述第二信息包括以下至少一项：Optionally, the second information includes at least one of the following:
随机接入相关上行信息；Random access related uplink information;
混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息；Hybrid Automatic Repeat reQuest (HARQ) feedback information;
上行参考信号信息；Uplink reference signal information;
上行控制信息UCI。Uplink control information UCI.
这里，在网络侧设备发送第一格式的第一信号后，终端需要根据第一格式的第一信号的接收来进行随机接入的发起，或下行信息的监听等。Here, after the network side device sends the first signal in the first format, the terminal needs to initiate random access or monitor downlink information according to the reception of the first signal in the first format.
其中，随机接入相关上行信息也就是终端根据第一格式的第一信号，在发起随机接入过程中，发送给网络侧设备的信息，如前导码(preamble)。该终端可以是被寻呼的终端，或被唤醒信号唤醒的终端。The random access related uplink information is information sent by the terminal to the network side device according to the first signal in the first format during the random access initiation process, such as a preamble. The terminal may be a paged terminal or a terminal awakened by an awakening signal.
其中，HARQ反馈信息可以是物理下行控制信道(Physical Downlink Control CHannel，PDCCH)相关反馈信息，即PDCCH的HARQ反馈；可以是物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)相关反馈信息，即PDSCH的HARQ反馈。Among them, the HARQ feedback information may be feedback information related to the physical downlink control channel (Physical Downlink Control CHannel, PDCCH), that is, the HARQ feedback of PDCCH; it may be feedback information related to the physical downlink shared channel (Physical Downlink Shared CHannel, PDSCH), that is, the HARQ feedback of PDSCH.
可选地，该实施例中，所述未接收到第二信息包括：在第一时间间隔内未接收到所述第二信息；Optionally, in this embodiment, the failure to receive the second information includes: failure to receive the second information within a first time interval;
其中，所述第一时间间隔的起始时间参考点为以下至少一项：The starting time reference point of the first time interval is at least one of the following:
第一时间单元的结束时刻，所述第一时间单元为发送所述第一格式的第一信号的最后一个时间单元；an end time of a first time unit, where the first time unit is a last time unit for sending the first signal in the first format;
第二时间单元的起始时刻，所述第二时间单元为所述第一时间单元的下一个时间单元；a starting time of a second time unit, where the second time unit is the next time unit of the first time unit;
所述第一格式的第一信号的检测时间窗的结束时刻。The end time of the detection time window of the first signal in the first format.
也就是说，若第一条件包括未接收到第二信息，网络侧设备会基于是否在第一时间间隔内未接收到第二信息，来确定是否满足第一条件。That is, if the first condition includes that the second information is not received, the network side device determines whether the first condition is met based on whether the second information is not received within the first time interval.
其中，第一时间间隔的起始时间参考点可以基于发送第一格式的第一信号的时间单元确定，可以基于第一格式的第一信号的检测时间窗的结束时刻。The starting time reference point of the first time interval may be determined based on a time unit for sending the first signal in the first format, or may be determined based on an end time of a detection time window of the first signal in the first format.
当然，第一时间间隔也可以是预先定义的，或网络侧设备配置的。Of course, the first time interval may also be predefined or configured by the network side device.
可选地，第一格式的第一信号的检测时间窗的结束时刻，包括：第一格式的第一信号的检测时间窗的结束时刻所在的时间单元的结束时刻。Optionally, the end time of the detection time window of the first signal in the first format includes: the end time of the time unit in which the end time of the detection time window of the first signal in the first format is located.
可选地，该实施例中，所述第一时间间隔的长度大于或等于所述第一信号的检测时间窗的长度。Optionally, in this embodiment, the length of the first time interval is greater than or equal to the length of the detection time window of the first signal.
这里，第一信号的检测时间窗是预先定义或网络侧设备配置的，终端会在第一信号的检测时间窗内检测第一信号。Here, the detection time window of the first signal is predefined or configured by a network-side device, and the terminal detects the first signal within the detection time window of the first signal.
需要说明的是，由于空闲(idle)/非激活(inactive)态的终端与网络侧存在可能的时 域偏差，因此，第一信号的检测时间窗是为了克服这种时域偏移所带来的第一信号检测错误。对于连接态终端，由于连接态终端与网络侧能够保持严格的时域同步，所以，第一信号检测时间窗可以理解为第一信号监听时机。It should be noted that there may be time delays between idle/inactive terminals and the network. Therefore, the detection time window of the first signal is to overcome the first signal detection error caused by the time domain offset. For the connected terminal, since the connected terminal and the network side can maintain strict time domain synchronization, the first signal detection time window can be understood as the first signal monitoring opportunity.
该实施例中，第一格式的第一信号的检测时间窗和第二格式的第一信号的检测时间窗可以相同，也可以不同。若第一格式的第一信号的检测时间窗和第二格式的第一信号的检测时间窗不同，第一时间间隔的长度大于或等于第一信号的检测时间窗的长度，即第一时间间隔的长度大于或等于第一格式的第一信号的检测时间窗的长度。In this embodiment, the detection time window of the first signal in the first format and the detection time window of the first signal in the second format may be the same or different. If the detection time window of the first signal in the first format and the detection time window of the first signal in the second format are different, the length of the first time interval is greater than or equal to the length of the detection time window of the first signal, that is, the length of the first time interval is greater than or equal to the length of the detection time window of the first signal in the first format.
可选地，该实施例中，所述接收到第一信息包括：在第三时间单元上接收所述第一信息；Optionally, in this embodiment, the receiving the first information includes: receiving the first information at a third time unit;
其中，所述第三时间单元包括以下至少一项：The third time unit includes at least one of the following:
预先定义或网络侧设备配置的时间单元；A time unit that is predefined or configured by network-side devices;
所述第一信号关联的反馈时间单元；a feedback time unit associated with the first signal;
与所述第一格式的第一信号所指示的反馈时间单元。The feedback time unit is indicated by the first signal in the first format.
也就是说，若第一条件包括接收到第一信息，网络侧设备会基于是否在上述第三时间单元上接收第一信息，来确定是否满足第一条件。That is, if the first condition includes receiving the first information, the network side device will determine whether the first condition is met based on whether the first information is received in the third time unit.
其中，可以预先定义或网络侧配置第一信号关联的反馈时间单元(即第一信号指示的时间单元)。所述第一格式的第一信号所指示的反馈时间单元，可以是距离第一格式的第一信号最近的反馈时间单元。反馈时间单元可以是用于反馈特定信息的时间单元，如用于反馈UCI的时间单元。Among them, the feedback time unit associated with the first signal (i.e., the time unit indicated by the first signal) can be predefined or configured on the network side. The feedback time unit indicated by the first signal of the first format can be the feedback time unit closest to the first signal of the first format. The feedback time unit can be a time unit for feeding back specific information, such as a time unit for feeding back UCI.
可选地，所述方法还包括：Optionally, the method further comprises:
所述网络侧设备接收所述终端发送的所述第一信号的格式推荐信息，所述格式推荐信息用于确定所述第一信号的格式。The network side device receives format recommendation information of the first signal sent by the terminal, where the format recommendation information is used to determine a format of the first signal.
这里，终端向网络侧设备发送第一信号的格式推荐信息，以使网络侧设备能够在接收该格式推荐信息后，基于该格式推荐信息确定第一信号的格式，包括第一格式和/或第二格式。Here, the terminal sends format recommendation information of the first signal to the network side device, so that the network side device can determine the format of the first signal, including the first format and/or the second format, based on the format recommendation information after receiving the format recommendation information.
可选地，所述网络侧设备发送第一格式的第一信号，包括：Optionally, the network side device sends a first signal in a first format, including:
所述网络侧设备根据所述格式推荐信息发送所述第一格式的第一信号。The network side device sends a first signal in the first format according to the format recommendation information.
也就是说，网络侧设备会按照终端推荐确定第一格式，发送该格式的第一信号。That is to say, the network side device will determine the first format according to the terminal recommendation and send the first signal in the format.
可选地，所述网络侧设备在满足第一条件的情况下，发送第二格式的第一信号，包括：Optionally, when the first condition is met, the network side device sends the first signal in the second format, including:
所述网络侧设备在满足第一条件的情况下，根据所述格式推荐信息发送第二格式的第一信号。When the first condition is met, the network side device sends the first signal in the second format according to the format recommendation information.
也就是说，网络侧设备会按照终端推荐确定第二格式，发送该格式的第一信号。That is to say, the network side device will determine the second format according to the terminal recommendation and send the first signal in the format.
作为一种实施方式，终端通过向网络侧设备发送格式推荐信息，推荐一个或多个第一信号的格式，网络侧设备可以在该一个或多个格式中选择第一格式和第二格式。或者，终端在网络侧设备发送第一格式的第一信号之前，发送格式推荐信息A，推荐一个或多个第 一信号的格式，网络侧设备可以在该一个或多个格式中选择第一格式；终端在网络侧设备发送第二格式的第一信号之前，发送格式推荐信息B，推荐一个或多个第一信号的格式，网络侧设备可以在该多个格式中选择第二格式。As an implementation mode, the terminal recommends one or more formats of the first signal by sending format recommendation information to the network side device, and the network side device can select the first format and the second format from the one or more formats. Alternatively, before the network side device sends the first signal in the first format, the terminal sends format recommendation information A to recommend one or more formats of the first signal. The format of a signal, the network side device can select a first format from the one or more formats; before the network side device sends a first signal in a second format, the terminal sends format recommendation information B to recommend one or more formats of the first signal, and the network side device can select a second format from the multiple formats.
当然，网络侧设备在接收该格式推荐信息后，也可以不基于该格式推荐信息确定第一信号的格式。因此，可选地，所述方法还包括：Of course, after receiving the format recommendation information, the network side device may not determine the format of the first signal based on the format recommendation information. Therefore, optionally, the method further includes:
所述网络侧设备根据配置信息或预设信息，确定所述第一格式和/或所述第二格式。The network side device determines the first format and/or the second format according to configuration information or preset information.
其中，配置信息可以是网络侧设备配置的，预设信息可以是预先定义的。如此，网络侧设备配置或预先定义确定第一格式和/或第二格式。The configuration information may be configured by the network side device, and the preset information may be predefined. In this way, the network side device configures or predefines the first format and/or the second format.
例如，网络侧设备配置了5种格式(如格式1～5)的第一信号，在配置信息或预设信息中，第一格式为格式1或2；第二格式为格式3，4，5。For example, the network side device is configured with first signals in five formats (such as formats 1 to 5).

可选地，第一格式和第二格式是相互关联的或不相互关联的。Optionally, the first format and the second format are interrelated or not interrelated.
若第一格式和第二格式是相互关联，则在第一格式确定的情况下，确定的第二格式是第一格式关联的格式，如在第一格式为格式1的情况下，由格式1和格式3关联，第二格式一定为格式3，不能为格式4。其中，第一格式跟第二格式的关联关系是网络侧配置或协议约定的。若第一格式和第二格式是不相互关联的，则在第一格式确定的情况下，确定的第二格式是随机确定的，如在第一格式为格式1的情况下，第二格式可以是格式3，4或者5。If the first format and the second format are interrelated, then when the first format is determined, the determined second format is the format associated with the first format, such as when the first format is format 1, format 1 is associated with format 3, and the second format must be format 3, and cannot be format 4. The association between the first format and the second format is a network-side configuration or protocol agreement. If the first format and the second format are not interrelated, then when the first format is determined, the determined second format is randomly determined, such as when the first format is format 1, the second format can be format 3, 4, or 5.
可选地，该实施例中，所述方法还包括：Optionally, in this embodiment, the method further includes:

如此，网络侧设备测量或者判断第一条件是否满足时，基于终端发送的测量量推荐信息来进行。In this way, when the network side device measures or determines whether the first condition is met, it is performed based on the measurement amount recommendation information sent by the terminal.

下面，结合具体场景说明本申请实施例的应用：The following describes the application of the embodiments of the present application in combination with specific scenarios:
场景一、第一信号存在反馈机制，第一条件为接收到第一反馈信息，第一反馈信息指示终端未接收到或错误接收到所述第一格式的第一信号。Scenario 1: There is a feedback mechanism for the first signal, and the first condition is receiving first feedback information, where the first feedback information indicates that the terminal has not received or has erroneously received the first signal in the first format.
网络侧设备在发送第一格式的第一信号后，若收到终端反馈的第一反馈信息，则发送第二格式的第一信号。After sending the first signal in the first format, if the network side device receives first feedback information fed back by the terminal, it sends the first signal in the second format.
其中，还可以预先定义或网络侧设备配置第三时间单元(网络侧设备接收第一反馈信息的时间单元)，如第三时间单元为与第一格式的第一信号所指示的、用于反馈UCI的时间单元。这样，网络侧设备在与第一格式的第一信号所指示的、用于反馈UCI的时间单元上接收到该第一反馈信息，才确定满足第一条件，发送第二格式的第一信号。Among them, a third time unit (a time unit for the network side device to receive the first feedback information) may also be predefined or configured by the network side device, such as a time unit for feeding back UCI indicated by the first signal of the first format. In this way, the network side device receives the first feedback information at the time unit for feeding back UCI indicated by the first signal of the first format, and then determines that the first condition is met and sends the first signal of the second format.
例如，网络侧设备在预先约定好的特定的时间单元内接收到所述第一信息。该特定的时间间隔为终端距离发送第一格式的控制信道/信号(第一信号)最近的反馈时间单元。反馈时间单元例如是用于反馈UCI的反馈时间单元。For example, the network side device receives the first information within a pre-agreed specific time unit. The specific time interval is the feedback time unit that is closest to the terminal for sending the control channel/signal (first signal) in the first format. The feedback time unit is, for example, a feedback time unit for feeding back UCI.
本实施例中，第一格式跟第二格式不同。例如，两种格式的所占的时域资源大小不同。第一格式(的控制信号/信道，下面简称为第一格式)所占的时域大小为1个slot。第二格式所占的时域大小为3个slot。可选地，第一格式跟第二格式所承载的比特数相同，例如10比特。第二格式由于所占的资源更大，资源开销更大，但覆盖性能更好了。因此，当网络侧设备发送了第一格式的控制信道/信号之后。如果收到终端发送的：没有接收到或错误的收到所述第一格式控制信号/信道的反馈信息，则网络在后续会发送第二格式的控制信道/信号，试图让终端能够接收到控制信道/信号。In this embodiment, the first format is different from the second format. For example, the two formats occupy different sizes of time domain resources. The time domain size occupied by the first format (control signal/channel, hereinafter referred to as the first format) is 1 slot. The time domain size occupied by the second format is 3 slots. Optionally, the first format and the second format carry the same number of bits, for example, 10 bits. The second format occupies more resources and has a larger resource overhead, but has better coverage performance. Therefore, after the network side device sends a control channel/signal in the first format. If the feedback information sent by the terminal is received: the control signal/channel of the first format is not received or is received incorrectly, the network will subsequently send a control channel/signal in the second format in an attempt to enable the terminal to receive the control channel/signal.
根据本实施例，网络能够通过终端的反馈情况，在一定条件下灵活的采用不同的控制信道/信号传输格式，从而实现在资源开销和覆盖性能之间做更好的折中。According to this embodiment, the network can flexibly adopt different control channel/signal transmission formats under certain conditions based on the feedback from the terminal, thereby achieving a better compromise between resource overhead and coverage performance.
场景二、第一信号不存在反馈机制。以第一信号为唤醒信号(LP-WUS)为例，LP-WUS的目的是触发idle/inactive态终端发起随机接入，或连接态终端进行PDCCH监听等。第一条件为未接收到第二信息，第二信息为随机接入相关上行信息(如发起随机接入信道(Random Access Channel，RACH)相关信息)、PDCCH的相关反馈信息、PDSCH的相关反馈信息中至少一项。Scenario 2: There is no feedback mechanism for the first signal. Taking the first signal as a wake-up signal (LP-WUS) as an example, the purpose of LP-WUS is to trigger idle/inactive terminals to initiate random access, or connected terminals to monitor PDCCH, etc. The first condition is that the second information is not received, and the second information is at least one of the following: random access-related uplink information (such as information related to initiating a random access channel (RACH)), PDCCH-related feedback information, and PDSCH-related feedback information.
故，网络侧设备在发送第一格式LP-WUS后，若没有接收到随机接入相关上行信息、PDCCH的HARQ反馈信息、PDSCH的HARQ反馈信息中至少一项，则发送第二格式LP-WUS。Therefore, after sending the first format LP-WUS, if the network side device does not receive at least one of the random access related uplink information, the HARQ feedback information of the PDCCH, and the HARQ feedback information of the PDSCH, it sends the second format LP-WUS.
可以理解的是，网络侧设备在发送LP-WUS之后，由于LP-WUS用于触发进行(包 括启动或恢复两层含义)PDCCH监听。网络侧设备会在终端恢复PDCCH监听后的一段时间内对终端进行调度，如果没有收到相关的HARQ反馈信息，则说明终端没有成功接收到LP-WUS。也就是，如果终端在接收到第一格式LP-WUS的时间单元之后的一段时间内未进行PDSCH或PDCCH的HARQ反馈信息的发送，则网络侧设备会发送覆盖性能更好的第二格式LP-WUS。It is understandable that after the network side device sends LP-WUS, since LP-WUS is used to trigger (packet The network side device will schedule the terminal within a period of time after the terminal resumes PDCCH monitoring. If no relevant HARQ feedback information is received, it means that the terminal has not successfully received LP-WUS. That is, if the terminal does not send HARQ feedback information of PDSCH or PDCCH within a period of time after receiving the time unit of the first format LP-WUS, the network side device will send the second format LP-WUS with better coverage performance.
其中，还可以预先定义或网络侧设备配置第一时间间隔，如第一时间间隔的起始时间参考点为发送第一格式LP-WUS的最后一个时间单元的结束时刻，第一时间间隔的长度大于LP-WUS的检测时间窗的长度。这样，网络侧设备在从发送第一格式LP-WUS的最后一个时间单元的结束时刻开始的、长度大于LP-WUS的检测时间窗长度的第一时间间隔内，没有接收到第二信息，才确定满足第一条件，发送第二格式LP-WUS。The first time interval may also be predefined or configured by the network side device, such as the starting time reference point of the first time interval is the end time of the last time unit for sending the first format LP-WUS, and the length of the first time interval is greater than the length of the detection time window of the LP-WUS. In this way, the network side device determines that the first condition is met and sends the second format LP-WUS only if it does not receive the second information within the first time interval starting from the end time of the last time unit for sending the first format LP-WUS and having a length greater than the length of the detection time window of the LP-WUS.
可选地，所述发起RACH相关信息包括：目标终端发起RACH。例如，目标终端指的是被寻呼的终端，或被唤醒信号唤醒的终端。可以理解的是，发起RACH的相关信息包括：preamble。Optionally, the information related to initiating RACH includes: the target terminal initiating RACH. For example, the target terminal refers to a terminal being paged, or a terminal being awakened by a wake-up signal. It can be understood that the information related to initiating RACH includes: preamble.
可选地，所述PDCCH的相关反馈信息指的是PDCCH的HARQ反馈。所述PDSCH的相关反馈信息指的是所述PDSCH的HARQ反馈。Optionally, the PDCCH-related feedback information refers to HARQ feedback of the PDCCH. The PDSCH-related feedback information refers to HARQ feedback of the PDSCH.
进一步地，所述第一条件为：在特定时间间隔内，没有收到第二信息。所述特定时间间隔由网络侧配置或协议约定。此外，可选地，所述特别时间间隔的起始时间参考点为：发送完所述第一格式的LP-WUS所在的时间单元的结束时刻或LP-WUS检测时间窗的结束时刻。Further, the first condition is: no second information is received within a specific time interval. The specific time interval is configured by the network side or agreed upon by the protocol. In addition, optionally, the starting time reference point of the special time interval is: the end time of the time unit in which the LP-WUS in the first format is sent or the end time of the LP-WUS detection time window.
可选地，所述第一格式的第一信号(控制信号/信道)的检测时间窗的结束时刻，包括：所述第一格式的控制信号/信道的检测时间窗的结束时刻所在的时间单元的结束时刻。Optionally, the end time of the detection time window of the first signal (control signal/channel) in the first format includes: the end time of the time unit in which the end time of the detection time window of the control signal/channel in the first format is located.
例如，特定时间间隔需要大于或等于LP-WUS的检测时间窗。终端会在协议约定或网络配置的LP-WUS检测时间窗内检测LP-WUS。For example, the specific time interval needs to be greater than or equal to the LP-WUS detection time window. The terminal will detect the LP-WUS within the LP-WUS detection time window agreed upon by the protocol or configured by the network.
需要说明的是，由于idle/inactive态的终端与网络侧存在可能的时域偏差，因此，LP-WUS检测时间窗是为了克服这种时域偏移所带来的LP-WUS检测错误。It should be noted that, since there may be a time domain deviation between the idle/inactive terminal and the network side, the LP-WUS detection time window is intended to overcome the LP-WUS detection error caused by this time domain deviation.
对于连接态终端，由于连接态终端与网络侧能够保持严格的时域同步，所以一种实施例中，所述LP-WUS检测时间窗可以理解为LP-WUS监听时机。For a connected terminal, since the connected terminal and the network side can maintain strict time domain synchronization, in an embodiment, the LP-WUS detection time window can be understood as an LP-WUS monitoring opportunity.
综上所述，本申请实施例的方法，网络侧设备发送第一格式的第一信号后，进一步根据第一条件灵活的选择第一信号的第二格式，实现了按照条件灵活选择第一信号格式的目的，能够在资源开销和覆盖性能之间做更好的折中。To sum up, in the method of the embodiment of the present application, after the network side device sends the first signal in the first format, it further flexibly selects the second format of the first signal according to the first condition, thereby achieving the purpose of flexibly selecting the first signal format according to the condition, and being able to make a better compromise between resource overhead and coverage performance.
