Description

Channel sending method, receiving method, device, equipment and network element

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on April 3, 2024, with application number 202410403737.1 and application name “Channel Transmission Method, Receiving Method, Device, Equipment and Network Element”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] To support the interconnection of hundreds of billions of devices and address the high network construction costs associated with large-scale IoE deployment, as well as the high operational costs associated with subsequent maintenance, such as battery replacement, a new type of Internet of Things (IoT) device is being designed within the 5G New Radio Access (NR) system: Ambient IoT (A-IoT). A-IoT devices have limited or no energy storage capabilities and are characterized by low complexity, low cost, and low power consumption, contributing to the realization of the perception and interconnection of everything.

[0004] In a 5G NR A-IoT communication system, different types of A-IoT devices with different capabilities may coexist. Currently, A-IoT devices can be divided into the following two types:

[0005] Type 1 devices: Peak power consumption is approximately 1 μW, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10 X ppm, the device has neither downlink nor uplink amplification capabilities. The device's uplink transmission is backscattered on an externally provided carrier.

[0006] Type II devices: peak power consumption ≤ several hundred μW, with energy storage capability, and initial sampling frequency offset (SFO) up to 10 X ppm, the device has downlink and / or uplink amplification capabilities. The device's uplink transmission can be generated internally by the device or backscattered on an externally provided carrier.

Depending on the form and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It can also use diversity transmission, precoded transmission, or beamforming transmission.

[0224] As shown in FIG2 , an embodiment of the present disclosure provides a channel sending method, the method comprising:

[0225] Step 201: A first device sends a target channel to a first network element, where the target channel includes at least one of the following formats or types:

[0226] a first channel format or type for transmission or reception of access information;

[0227] Second channel format or type for sending or receiving short messages;

[0228] A third channel format or type for long message transmission or reception;

[0229] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0230] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0231] In some embodiments, the target channel refers to the physical channel that the device sends to the first network element, which may also be called the A-IoT uplink channel. In some embodiments, the target channel is a physical device to reader channel (PDRCH).

[0232] In some embodiments, the downlink channel refers to a physical channel sent by the first network element to the device, which may also be called an A-IoT downlink channel. In some embodiments, the downlink channel is a physical reader to device channel (PRDCH).

[0233] As a specific embodiment, the first network element includes at least one of the following: a reader, a base station, a terminal, an intermediate node, and other network elements.

[0234] In some embodiments, the first device is an ambient Internet of Things (A-IoT) device.

[0235] In at least one embodiment of the present disclosure, the downlink channel identification information includes at least one of the following: an index number of the downlink channel, an index number of a command type carried by the downlink channel, a communication process number of the downlink channel, and an index number of a query signal of the downlink channel.

[0236] The downlink channel is a channel sent by the first network element to the first device before the target channel is sent.

[0237] In some embodiments, there may be multiple downlink channels. To distinguish which downlink channel the target channel is a backscatter channel or response channel for, embodiments of the present disclosure add downlink channel identification information to the target channel. Specifically, the downlink channel identification information indicates the downlink channel to which the channel of the fifth channel format or type responds.

[0238] In other words, the downlink channel identification information carried by the fifth channel format or type of the target channel is used to indicate to the first network element the identification information of the downlink channel previously sent by the first network element to the device, so that the first network element can know the correspondence between the target channel and the downlink channel to which it responds.

[0239] In one implementation, the preamble sequence of the target channel is used to indicate a device type, a device capability, or a first network element identifier.

[0240] For example, the preamble of the target channel is used to indicate the device type; for example, specific preamble sequence 1 is used to indicate that the device type is type 1 device; specific preamble sequence 2 is used to indicate that the device type is type 2a device; and specific preamble sequence 3 is used to indicate that the device type is type 2b device.

[0241] For another example, the preamble of the target channel is used to indicate the device capability; for example, the specific preamble sequence 4 is used to indicate that the device does not have a certain capability, such as frequency shift capability; the specific preamble sequence 5 is used to indicate that the device has a certain capability, such as frequency shift capability.

[0242] For another example, the preamble of the target channel is used to indicate the first network element identifier, and the first network element identifier is used to indicate the target object of the target channel; for example, a preamble sequence in a specific format is used, including: a preamble sequence starting with 101010 indicates that the preamble sequence carries the first network element identifier, and the last N bits of the preamble sequence are used to represent the first network element identifier.

[0243] In at least one embodiment of the present disclosure, as shown in FIG4 , the target channel (Type 1 PDRCH) of the first channel format or type carries at least one of the following information:

[0244] A preamble, which is used to complete synchronization between the first device and the first network element; the preamble may also carry other information, such as device capabilities;

[0245] a target channel format or type (PDRCH Type), where the target channel format or type is used to indicate the format or type of the target channel;

[0246] Access information (information for accessing), the access information being used to carry access information of the first device, the access information including at least one of a random identifier, a temporary identifier, and a random number; in some embodiments, the access information includes: contention-based access information and / or slot-based Aloha access information;

[0247] Cyclic Redundancy Check (CRC): The cyclic redundancy check is used to check the correctness of transmitted data.

[0248] To establish a communication connection with the first network element, the device must first complete random access and acquire communication resources. Therefore, the first channel format or type of target channel is applicable to scenarios where, during a random access process, the first device sends random access information to the first network element, transmitting a random identifier, a temporary identifier, a random number, etc. This random access information may be a response to a downlink channel message sent by the first network element to the device, or it may be an active random access message sent autonomously by the device.

[0249] By adopting the above-mentioned design of the first channel format or type for sending or receiving access information, the first channel format or type field can be used to indicate that the target channel is random access information, thereby facilitating the device to receive random access information.

[0250] In at least one embodiment of the present disclosure, as shown in FIG5 , the second channel format or type of target channel (Type2PDRCH) carries at least one of the following information:

[0251] A preamble, which is used to complete synchronization between the first device and the first network element; the preamble may also carry other information, such as device capabilities;

[0253] Device ID, which is used to carry identification information of the first device. The device identification information includes: an identifier or serial number of the device;

[0254] Cyclic Redundancy Check (CRC): The cyclic redundancy check is used to check the correctness of transmitted data.

[0255] In some embodiments, the applicable scenario of the target channel of the second channel format or type is: after receiving the downlink channel sent by the first network element, the device sends a response message (i.e., the target channel) to the first network element, which includes its device identifier information, so that the first network element can know the identifier of the responding device.

[0256] By adopting the above-mentioned design of the second channel format or type for sending or receiving short messages, the identifier information of the device can be indicated through the device identifier field, thereby facilitating the first network element to receive device response information and identify the responding device.

[0257] In at least one embodiment of the present disclosure, as shown in FIG6 , the target channel of the third channel format or type (Type 3 PDRCH) carries at least one of the following information:

[0264] In some embodiments, the target channel of the third channel format or type is applicable to a scenario where, after receiving a downlink channel from a first network element, the device sends a response message to the first network element, including its device identifier information, so that the first network element can obtain the identifier of the responding device. Simultaneously, the device also sends data information (e.g., sensor data) to the first network element in the target channel.

[0265] By adopting the above-mentioned design of the third channel format or type for sending or receiving long messages, the target channel format or type field can be used to indicate that the target channel is a long message, thereby facilitating the first network element to receive the long message.

[0266] In at least one embodiment of the present disclosure, as shown in FIG7 , the target channel of the fourth channel format or type (Type 4 PDRCH) carries at least one of the following information:

[0267] A preamble, which is used to complete synchronization between the first device and the first network element; the preamble may also carry other information, such as device capabilities;

[0268] a target channel format or type (PDRCH Type), where the target channel format or type is used to indicate the format or type of the target channel;

[0269] Device ID, which is used to carry identification information of the first device. The device identification information includes: an identifier or serial number of the device;

[0270] A first network element identifier (Reader ID), where the first network element identifier is used to carry identification information of the first network element and indicates a target object for sending the target channel;

[0271] Cyclic Redundancy Check (CRC): The cyclic redundancy check is used to check the correctness of transmitted data.

[0272] The fourth channel format or type of target channel is applicable when, after receiving a downlink channel from a first network element, a device sends a response message to the first network element containing its device identifier, allowing the first network element to obtain the identifier of the responding device. The target channel also contains the first network element identifier, indicating to the first network element the target recipient of the target channel.

[0273] By adopting the above-mentioned design scheme of the fourth channel format or type for sending or receiving short messages with the first network element identifier, the target channel format or type field can be used to indicate that the target channel is a short message with the first network element identifier, thereby facilitating the first network element to receive the information.

[0274] In at least one embodiment of the present disclosure, as shown in FIG8 , the target channel of the fifth channel format or type (Type5PDRCH) carries at least one of the following information:

[0275] A preamble, which is used to complete synchronization between the first device and the first network element; the preamble may also carry other information, such as device capabilities;

[0276] a target channel format or type (PDRCH Type), where the target channel format or type is used to indicate the format or type of the target channel;

[0277] Device ID, which is used to carry identification information of the first device. The device identification information includes: an identifier or serial number of the device;

[0278] Downlink channel identification information (PRDCH ID), where the downlink channel identification information is used to indicate identification information of a downlink channel sent by the first network element to the first device;

[0279] Cyclic Redundancy Check (CRC): The cyclic redundancy check is used to check the correctness of transmitted data.

[0280] In some embodiments, the fifth channel format or type of target channel is applicable to scenarios where, after receiving a downlink channel message sent by a first network element, a device sends a response message to the first network element, which includes its device identifier information, so that the first network element can obtain the identifier of the responding device. The target channel message also includes a downlink channel index number, which indicates to the first network element the identification information of the downlink channel to which the target channel message sent by the device corresponds.

[0281] By adopting this design of the fifth channel format or type for sending or receiving short messages with downlink channel identification information, the target channel format or type field can be used to indicate that the target channel is for short messages with second channel identification information, thereby facilitating the reader to receive the information.

[0282] In an optional implementation, when the target channel includes two formats or types, the target channel includes:

[0283] the first channel format or type and the second channel format or type; or,

[0284] said first channel format or type and said third channel format or type; or,

[0293] The first channel format or type, the second channel format or type, the third channel format or type, and the fifth channel format or type.

[0294] In summary, in the embodiment of the present disclosure, the first device sends a target channel to the first network element, and the target channel includes at least one format or type of a first channel format or type for sending or receiving access information, a second channel format or type for sending or receiving short messages, a third channel format or type for sending or receiving long messages, a fourth channel format or type for sending or receiving short messages with a first network element identifier, and a fifth channel format or type for sending or receiving short messages with downlink channel identification information; this method enables different types of devices with different capabilities to send target channels of different formats or types to the first network element, so that one channel can be used to be compatible with multiple information such as access information, device information or data information, and is also compatible with first type devices and second type devices, allowing low-complexity first type devices to complete basic operations, and high-complexity second type devices to complete more operations. At the same time, one channel can also adapt to multiple application scenarios, thereby simplifying system design, reducing device complexity and cost, and saving device power consumption.

At the same time, one channel can also adapt to multiple application scenarios, thereby simplifying system design, reducing device complexity and cost, and saving device power consumption.

[0356] In order to more clearly describe the channel sending method and receiving method provided by the embodiments of the present disclosure, the target channel is described below with reference to several examples.

[0357] Example 1: The target channel carries information in the preamble

[0358] The first device sends a target channel to the first network element, where the target channel includes at least one of the following formats or types:

[0359] a first channel format or type for transmission or reception of access information;

[0360] Second channel format or type for sending or receiving short messages;

[0361] A third channel format or type for long message transmission or reception;

[0362] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0363] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0364] In this example, specifically:

[0365] In addition to being used for synchronization, the preamble in the target channel can also be used to indicate the device type, device capabilities, or first network element identifier. After receiving the preamble sent by the device, the first network element can obtain the device type, device capabilities, or first network element identifier of the device that sent the preamble from the preamble.

[0366] Among them, the preamble of the target channel is used to indicate the device type; for example, specific preamble sequence 1 is used to indicate that the device type is type 1 device; specific preamble sequence 2 is used to indicate that the device type is type 2a device; specific preamble sequence 3 is used to indicate that the device type is type 2b device.

[0367] As shown in FIG9 , the first device generates a specific preamble sequence 1 and sends it to the first network element, and the second device generates a specific preamble sequence 2 and sends it to the first network element; the first network element determines that the first device is a type 1 device and the second device is a type 2a device.

[0368] This example uses a leading sequence to indicate the device type, device capability or reader identifier. A specific leading sequence can be used to indicate the device type, device capability or first network element identifier information of the device sending the leading sequence, so that the first network element can obtain this information, which is beneficial for the first network element to perform subsequent operations and processing based on this information.

[0369] Example 2: Downlink channel identification information in the target channel of the fifth channel format or type

[0370] The first device sends a target channel to the first network element, where the target channel includes at least one of the following formats or types:

[0371] a first channel format or type for transmission or reception of access information;

[0372] Second channel format or type for sending or receiving short messages;

[0373] A third channel format or type for long message transmission or reception;

[0374] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0375] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0376] In this example, specifically:

[0377] The downlink channel identification information in the target channel is used to indicate the index number of the downlink channel sent by the first network element to the device:

[0378] The downlink channel is the channel sent by the first network element to the device before the target channel is sent. There may be multiple downlink channels. To distinguish which downlink channel the target channel is the backscatter channel or response channel for, the downlink channel index number needs to be added to the target channel.

[0379] The target channel transmits the downlink channel index number for indicating to the first network element the index number of the downlink channel previously sent by the first network element to the device, so that the first network element can know the correspondence between the target channel and the downlink channel to which it responds.

[0380] As shown in FIG10 , the first network element sends a downlink channel with an index number of 2 and a downlink channel with an index number of 4 to the first device. The first device determines that the target channel is a response to the downlink channel with an index number of 2. The first device sends the target channel with the downlink channel index number of 2 to the first network element.

[0381] The first network element sends a downlink channel with an index number of 1, a downlink channel with an index number of 3, and a downlink channel with an index number of 5 to the second device. The second device determines that the target channel is a response to the downlink channel with an index number of 3, and the second device sends the target channel with the downlink channel index number of 3 to the first network element.

[0382] The first network element determines that the target channel sent by the first device is a response to the downlink channel with an index number of 2, and the target channel sent by the second device is a response to the downlink channel with an index number of 3.

[0383] This example uses a solution of downlink channel identification information, and the target channel identification information can be used to indicate the identifier of the downlink channel sent by the first network element to the device, so that the first network element can obtain which downlink channel sent by the first network element the target channel sent by the device is in response to, which is beneficial for the first network element to perform subsequent operations and processing based on this information.

[0384] Example 3: The target channel contains two formats or types

[0385] The first device sends a target channel to the first network element, where the target channel includes at least one of the following formats or types:

[0386] a first channel format or type for transmission or reception of access information;

[0387] Second channel format or type for sending or receiving short messages;

[0388] A third channel format or type for long message transmission or reception;

[0389] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0390] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0391] In this example, specifically:

[0392] The target channel includes a first channel format or type for sending or receiving access information, and a second channel format or type for sending or receiving short messages.

[0393] That is, based on the target channel type or format field in the target channel, the target channel can be divided into two formats or types: a first channel format or type for sending or receiving access information, and a second channel format or type for sending or receiving short messages. This facilitates the device to send the first channel format or type for sending or receiving access information, or the second channel format or type for sending or receiving short messages to the first network element according to different scenarios and requirements.

[0394] To establish a communication connection with a first network element, a device must first complete random access and acquire communication resources. Therefore, during the random access process, the first device sends random access information to the first network element, transmitting a random identifier, temporary identifier, random number, etc. After completing random access, the device receives a downlink channel from the first network element and then sends a response message to the first network element containing its device identifier information, allowing the first network element to obtain the identifier of the responding device.

[0395] A design scheme in which the target channel includes two formats or types is adopted. The device can send target channels of different formats or types according to the scenario or requirements, and the device can also indicate through the target channel format or type field whether the specific type of the target channel is for the first channel format or type, or the second channel format or type, thereby facilitating the first network element to receive the target channel according to the target channel format or type field.

[0396] Example 4: The target channel contains three formats or types

[0397] The first device sends a target channel to the first network element, where the target channel includes at least one of the following formats or types:

[0398] a first channel format or type for transmission or reception of access information;

[0399] Second channel format or type for sending or receiving short messages;

[0400] A third channel format or type for long message transmission or reception;

[0401] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0402] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0403] In this example, specifically:

[0404] The target channel includes a first channel format or type for sending or receiving access information, a second channel format or type for sending or receiving short information, and a third channel format or type for sending or receiving long information.

[0405] That is, based on the target channel type or format field in the target channel, the target channel can be divided into three formats or types: a first channel format or type for sending or receiving random access information, a second channel format or type for sending or receiving short messages, and a third channel format or type for sending or receiving long messages. This facilitates the device to send the first channel format or type for sending or receiving random access information, the second channel format or type for sending or receiving short messages, and the third channel format or type for sending or receiving long messages to the first network element according to different scenarios and requirements.

[0406] In order to establish a communication connection with the first network element, the device first needs to complete random access and obtain communication resources. Therefore, the applicable scenario is that during the random access process, the first device sends random access information to the first network element, transmitting a random identifier, a temporary identifier, a random number, etc. After completing the random access, after receiving the downlink channel sent by the first network element, the device sends a response message to the first network element, which includes its device identifier information, so that the first network element can know the identifier of the responding device. Alternatively, the device sends data information (for example, sensor data) to the first network element in the target channel.

[0407] By adopting a design scheme in which the target channel includes three formats or types, the device can send target channels of different formats or types according to the scenario or requirements, and the device can also indicate through the target channel format or type field whether the specific type of the target channel is a first channel format or type for sending or receiving random access information, a second channel format or type for sending or receiving short messages, or a third channel format or type for sending or receiving long messages, thereby facilitating the first network element to receive the target channel according to the target channel format or type field.

[0408] Example 5: The target channel contains four formats or types

[0409] The first device sends a target channel to the first network element, where the target channel includes at least one of the following formats or types:

[0410] a first channel format or type for transmission or reception of access information;

[0411] Second channel format or type for sending or receiving short messages;

[0412] A third channel format or type for long message transmission or reception;

[0413] a fourth channel format or type for sending or receiving a short message with the first network element identifier;

[0414] The fifth channel format or type used for sending or receiving short messages with downlink channel identification information.

[0415] In this example, specifically:

[0416] The target channel includes a first channel format or type for sending or receiving access information, a second channel format or type for sending or receiving short messages, a third channel format or type for sending or receiving long messages, and a fourth channel format or type for sending or receiving short messages with a first network element identifier.

[0417] That is, according to the target channel type or format field in the target channel, the target channel can be divided into four formats or types: a first channel format or type for sending or receiving access information, a second channel format or type for sending or receiving short messages, a third channel format or type for sending or receiving long messages, and a fourth channel format or type for sending or receiving short messages with the first network element identifier. This facilitates the device to send the first channel format or type for sending or receiving access information, the second channel format or type for sending or receiving short messages, the third channel format or type for sending or receiving long messages, and the fourth channel format or type for sending or receiving short messages with the first network element identifier to the first network element according to different scenarios and requirements.

[0418] In order to establish a communication connection with the first network element, the device first needs to complete random access and obtain communication resources. Therefore, the applicable scenario is that during the random access process, the first device sends random access information to the first network element and transmits a random identifier, a temporary identifier, a random number, etc. After completing the random access, after receiving the downlink channel sent by the first network element, the device sends a response message to the first network element, which includes its device identifier information, so that the first network element can know the identifier of the responding device. Alternatively, the device sends data information (for example, sensor data) to the first network element in the target channel. Alternatively, the target channel also includes a first network element identifier, which is used to indicate to the first network element the target object of the target channel.

[0419] By adopting a design scheme in which the target channel includes four formats or types, the device can send target channels of different formats or types according to the scenario or needs, and the device can also indicate through the target channel format or type field whether the specific type of the target channel is a first channel format or type for sending or receiving access information, a second channel format or type for sending or receiving short messages, a third channel format or type for sending or receiving long messages, or a fourth channel format or type for sending or receiving short messages with a first network element identifier, thereby facilitating the first network element to receive the target channel according to the target channel format or type field.
