[0034] The specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0035] As shown in FIG. 1, the system architecture includes: a terminal 101 and a network device 102; wherein the terminal 101 interacts with the network device 103 through the network 102.

[0036] It should be noted that the medium providing the communication link between the terminal 101 and the network device 103 can be a wired network or a wireless network.

[0037] Optionally, the wireless or wired networks described above use standard communications technologies and / or protocols. The network can be the Internet, but can also include any combination of LANs, MANs, WANs, mobile, wired, or wireless networks, networks of networks, and / or intranets. In some embodiments, technologies used include, without limitation, Hypertext Markup Language (HTML), Extensible Markup Language (XML), and / or the like, to create and transmit data over the network. In addition, conventional encryption technologies such as the Secure Sockets Layer (SSL), Transport Layer Security (TLS), Virtual Private Networks (VPNs), Internet Protocol Security (IPSec), and / or the like, can be used to encrypt all or some of the links between nodes in the network. In other embodiments, custom and / or proprietary data communications technologies can be used in place of, or in addition to, the above technologies.

[0038] The terminal 101 can be a user equipment, a terminal device, an access device, a subscriber unit, a subscriber terminal, or a user device, etc.

[0039] In an embodiment, the terminal 101 can be a device that provides voice / data to a user, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. For example, the terminal 101 can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile Internet device, a virtual reality device, an augmented reality device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart power grids, a wireless terminal in transportation safety, a wireless terminal in smart cities, a wireless terminal in smart homes, a cellular phone, etc. The embodiments of the present disclosure do not make specific limitations on this.

[0040] In the embodiments of the present disclosure, the terminal 101 can also be a terminal device in an IoT system. IoT can connect objects to a network through communication technology, so as to realize human-computer interaction and intelligent network of all things. For example, the terminal 101 can be understood as an IoT device, or an IoT device terminal. Specifically, it can be understood as an ambient IoT terminal or a passive IoT device terminal. The terminal 101 can also be referred to as a UE (User Equipment, user equipment).

[0041] In some embodiments, the network device 103 can be a base station, a relay or an access point, etc. The base station can be, but is not limited to, a 5G and later version base station (for example, a gNB base station), or a base station in other communication systems (for example, an eNB base station).

[0042] Those skilled in the art can know that the number of terminals and network side devices in FIG. 1 is only illustrative, and any number of terminals, network side devices can be provided according to actual needs. The embodiments of the present disclosure do not limit this.

[0043] In the related art, the 3GPP organization proposes the concept of ambient IoT, which does not need to rely on a battery, but obtains energy from the environment or radio frequency signals to perform waveform modulation and transmission. Since it is expected that the product can be low-cost, low-power and low-complexity, limited by cost, the IoT terminal has poor crystal oscillator difference, sampling and timing functions. At the same time, the new radio (NR) uses a physical downlink control channel (PDCCH) to transmit control information, but the IoT product expects to be low-cost, low-power and low-complexity, and cannot support the blind detection process of the PDCCH of the NR. A new standard needs to be developed for IoT to define the content of the control information, so that the network side device is simpler to schedule the IoT device.

[0044] However, the 3GPP organization has not yet concluded what content should be included in the control information of the IoT device. How to design the content of the control information of the IoT device has become a technical problem to be solved.

[0045] Under the above system architecture, in order to at least partially solve the above technical problems, the disclosure embodiment provides a control information indication method of an Internet of Things device, which can be executed by any electronic device with computing processing capability. In some embodiments, the control information indication method of the Internet of Things device provided in the disclosure embodiment can be executed by the Internet of Things device of the above system architecture; in other embodiments, the control information indication method of the Internet of Things device provided in the disclosure embodiment can be implemented by the network side device (such as a base station) in the above system architecture; in other embodiments, the control information indication method of the Internet of Things device provided in the disclosure embodiment can also be implemented through the interaction between the network side device and the Internet of Things device.

[0060] The specific content of the information of the D2R transmission and / or the R2D transmission will be described below.

[0061] In one embodiment, the transmission block information of the D2R transmission and / or the R2D transmission indicates the transmission block information of the current control information transmission, the transmission block information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or the transmission block information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the transmission block information includes at least one of the following information: the size of the data block to be transmitted; the bit length of the transmission; the end occasion of the time domain of the transmission.

The indication object of the transport block information of the R2D transmission is similar to that of the transport block information of the D2R transmission, which will not be described herein again. It should be noted that the indication object of the control information to the first device can be determined according to actual conditions.

[0064] The transport block is a data block transmitted each time, and is a basic unit of uplink transmission and downlink transmission.

[0065] The size of the data block to be transmitted is used to represent the number of data blocks occupied by the control information to be transmitted, which can be in bits or bytes. The bit length of the transmission is used to represent the number of binary bits occupied by the control information to be transmitted. The time domain end position of the transmission is used to represent the value of the last time point of the transport block information of the transmission.

The code rate information includes at least one of the following information: code rate size; and code rate type.

[0069] It should be noted that the indication object of the code rate information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the transport block information, which will not be described herein again.

[0070] In an embodiment, the code rate size is used to represent the speed of the current control information. The code rate size can include 1, 0.5, 0.25, 0.125, 0.0625, 0.03125, 0.015625, or no indication.

[0071] The encoding type of the code rate is used to represent the encoding mode of the code rate. The encoding type of the code rate can include linear encoding, forward error correction encoding (FEC code), cyclic redundancy check code (CRC code), or no encoding.

[0072] The linear encoding can be Manchester code, Miller code, FM0 code, etc. The forward error correction encoding can use convolutional code, which includes zero bit convolutional code (Zero Tail CC, ZTCC) or tail biting convolutional code (Tail Biting CC, BTCC). The ZTCC adds K (K is the constraint length) 0s at the end of the code word to output the last state of the encoding register during encoding, and the TBCC directly initializes the encoding register with the last K bits of the code word to improve the encoding rate. The cyclic redundancy check code can be 6-bit CRC code or 16-bit CRC code, etc.

[0073] It should be noted that the code rate size and the encoding type of the control information can be pre-configured, and the specific information can be determined according to the actual situation, and the present disclosure does not make specific limitations thereto.

[0074] In an embodiment, the encoding information of the D2R transmission and / or the R2D transmission indicates the encoding information of the current control information transmission, the encoding information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or the encoding information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the encoding information includes at least one of the following information: encoding type and encoding mode.

[0075] The encoding type includes at least one of linear encoding, forward error correction encoding, cyclic redundancy check encoding, and no encoding.

For example, the R2D transmission adopts a combination of Manchester code in linear encoding and convolution code in forward error correction encoding, or a combination of PIE encoding in linear encoding and 6-bit cyclic redundancy check in cyclic redundancy check encoding. The convolution code can include ZTCC or BTCC.

[0077] The encoding mode of the D2R transmission includes linear encoding, forward error correction encoding, or cyclic redundancy check code, wherein the linear encoding of the D2R transmission includes at least one of Manchester code, FM0 encoding, Miller encoding, or no encoding; the forward error correction encoding of the D2R transmission includes at least one of convolution code, LDPC code, Polar code, Turbe code, parity check code, or no encoding; and the cyclic redundancy check code of the D2R encoding includes at least one of 6-bit cyclic redundancy check, 16-bit cyclic redundancy check, or no cyclic redundancy check.

[0079] The encoded information is used to represent the encoding mode of different targets. When the control information includes the encoded information of the R2D transmission, Manchester code, PIE encoding, or no encoding can be used alone, or Manchester code and PIE encoding can be used. Correspondingly, when the control information includes the encoded information of the D2R transmission, linear encoding, forward error correction encoding, or cyclic redundancy check code can be used alone, or a combination of at least two of the above encoding modes can be used.

[0080] It should be noted that the indication object of the encoded information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the aforementioned transport block information, which will not be described here.

[0081] In an embodiment, the modulation information of the D2R transmission and / or the R2D transmission indicates modulation information of the current control information transmission, modulation information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or modulation information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the modulation information includes at least one of the following modulation modes: binary on-off keying (OOK); frequency-shift keying (FSK); binary phase shift keying (BPSK).

[0082] OOK, also known as binary amplitude shift keying, is to control the on and off of the sinusoidal carrier with unipolar non-return-to-zero code sequence. For example, one amplitude represents logic 0, and the other amplitude represents logic 1.

[0083] FSK is a modulation mode that controls the carrier frequency change with digital signals. According to whether the phase of the modulated wave is continuous or not, FSK is divided into phase discontinuous FSK and phase continuous FSK. For example, a higher frequency represents logic 1, and a lower frequency represents logic 0.

[0084] BPSK is a conversion mode that converts analog signals into data values. It uses a complex wave combination with a phase offset to represent information keying phase shift. For example, BPSK uses a reference sine wave and a phase-inverted wave to represent logic 0 with the sine wave and logic 1 with the phase-inverted wave.

[0085] In an embodiment, when the modulation mode adopts OOK, the method further includes: indicating OOK, and the indication content includes at least one of the following:

[0086] M value of OOK, the M value being the number of chips available in each OFDM symbol;

[0087] Chip rate of OOK;

[0088] At least one of the following: sequence type, sequence generation parameter, and sequence length of OOK;

[0089] Chip length of OOK.

[0090] It should be noted that the M value can be a specific integer in the range of 1-32, for example, M is at least one of 1, 2, 4, 8, 16, and 32.

[0091] The chip rate is the symbol rate after spreading. Spreading is to multiply the user data symbol with the corresponding spreading code assigned to it. Spreading operation will increase the signal bandwidth. By spreading, bits can be converted into chips.

[0092] Under OOK modulation, binary bits can be encoded into a series of pulses or time intervals, the width of the pulses can represent 0 or 1. The sequence generation parameters of OOK can include the width of the pulse or the length of the time interval, etc. The width of the pulse can be considered as the chip length of OOK, for example, 256 sampling points or 41.67us. The sequence length of OOK is the sequence length for spreading operation, for example, for an IoT signal with 1RB bandwidth, the spreading sequence length is 1RB, i.e. 12 long. The spreading sequence is generally a constant modulus sequence with the same modulus but different phases.

[0093] In an embodiment, when the modulation mode adopts FSK, the method further comprises: indicating FSK, the indication content including at least one of the target frequency value, the frequency shift value.

[0094] When FSK modulation is adopted, two frequencies f1 and f2 are used as target frequency values, f1 and f2 are different carrier frequencies. When transmitting logic 0, a carrier with frequency f1 is sent, and when transmitting logic 1, a carrier with frequency f2 is sent. The frequency shift value is the difference between f2 and f1, which is used to characterize the difficulty of signal discrimination by multiple waveforms with the same energy.

[0095] In an embodiment, the repetition transmission information of the D2R transmission and / or the R2D transmission indicates the repetition transmission information of the current control information transmission, the repetition transmission information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or the repetition transmission information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the repetition transmission information includes at least one of the following information: repetition transmission times; repetition transmission granularity.

[0096] The indication object of the repetition transmission information of the D2R transmission and / or the R2D transmission is the same as the determination method of the transmission block information in the foregoing embodiments, which will not be described here.

[0097] The repetition transmission times can be determined according to whether repetition transmission is needed in the information transmission process, for example, the number of times of timeout retransmission or fast retransmission.

[0098] The repetition transmission granularity includes the transmission block level, the bit level, and the chip level. The transmission block level means that the repetition unit is a transmission block, i.e. one repetition transmission is performed after the transmission of one transmission block is completed. The chip level means that the repetition unit is a chip, i.e. one repetition transmission is performed immediately after the transmission of one chip is completed.

[0099] Bit level refers to a repetition unit of a bit, that is, one bit is transmitted and one repetition transmission is performed for the bit. Considering that a bit can be linearly and / or FEC encoded to be inconsistent with a source bit stream, bit level repetition transmission can be further divided into transmission before linear encoding and / or FEC encoding of each bit or transmission after linear encoding and / or FEC encoding of each bit.

[0100] In one embodiment, the transmission segment indication information of the D2R transmission and / or the R2D transmission indicates transmission segment indication information of the current control information transmission, transmission segment indication information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or transmission segment indication information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information. The transmission segment indication information is used to represent one-time transmission or segmented transmission. For example, in the D2R transmission, the length of the transmission block exceeds the length of the pre-defined or pre-configured network side time domain detection window, and segmented transmission is required to avoid detection failure and affect other signals.

[0101] The indication object of the transmission segment indication information of the D2R transmission and / or the R2D transmission is the same as the determination manner of the transmission block information in the foregoing embodiments, which will not be described herein.

[0102] The transmission segment indication information can be 1-bit information. For example, bit 1 represents segmented transmission, and bit 0 represents one-time transmission, or bit 0 represents segmented transmission, and bit 1 represents one-time transmission.

The time domain resource information includes at least one of a time domain resource length and time domain resource position information.

[0104] The indication object of the time domain resource information of the D2R transmission and / or the R2D transmission is the same as the determination manner of the transmission block information in the foregoing embodiments, which will not be described herein.

[0105] The time domain resource length, also referred to as the time domain resource size, is used to represent the size of the time domain resource occupied in the transmission, and can also be used to implicitly indicate the end position of the time domain. In the time domain resource length of 5G NR, a radio frame, a subframe, a slot, and an OFDM symbol are included. The length of a radio frame is 10 ms, one radio frame includes 10 subframes, and one slot includes 14 OFDM symbols. It should be noted that in the Internet of Things communication system of the present disclosure, the time domain resource length of NR can be multiplexed.

[0106] The time domain resource location information includes start location information and / or end location information. For example, the time domain resource location information can include only the start location information or the end location information, or include both the start location information and the end location information.

[0108] The absolute start location information can indicate a start location of Xth granularity for R2D transmission or D2R transmission, where X is an offset value relative to the absolute location. For example, the Xth granularity is the 273rd chip, which is used to express that the start location is at the position corresponding to the 273rd chip.

[0109] The absolute start location information within the preset first time granularity can indicate, for example, the Yth chip within an OFDM symbol as the absolute start location.

[0110] In the offset information of the start location or the end location relative to the time point at which the current configuration information is located within the preset second time granularity, and the offset information of the start location or the end location relative to the most recent transmission cycle location of the indication information within the preset third time granularity when the indication information is periodic transmission, the offset information includes:

[0111] A preset granularity value, the preset granularity value is a fixed value, for example, the offset information is Z granularities, where Z is a natural number;

[0112] A minimum time interval granularity from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission, which represents a minimum value Tmin from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission;

[0113] A maximum time interval granularity from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission, which represents a maximum value Tmin from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission; or

[0114] The offset time point from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission needs to be transmitted within a preset time range, and the preset time range can be configured as [Tmin, Tmax].

[0115] It should be noted that the preset granularity value, the minimum time interval granularity, the maximum time interval granularity, and the preset time interval can be preconfigured, and specific values can be determined according to actual requirements, and the present disclosure does not limit this.

[0117] The absolute end position information, for example, can indicate an end position of an R2D transmission or a D2R transmission in an Mth granularity, and M is an offset relative to an absolute position. For example, the Mth granularity is 273 chips, and is used to indicate that the end position is at a position corresponding to the 273th chip.

[0118] The absolute end position information within the preset fourth time granularity, for example, can indicate an Nth chip within an OFDM symbol as an end position.

[0119] The offset information in the offset information of a start position or an end position relative to a time point at which the current configuration information is located within a preset fifth time granularity; or offset information of a start position or an end position relative to a transmission cycle position closest to the indication information within a preset sixth time granularity when the indication information is periodic transmission includes: a preset granularity value; a minimum time interval granularity from a time point at which the current configuration information is located to the R2D transmission or the D2R transmission; a maximum time interval granularity from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission; or an offset time point from the time point at which the current configuration information is located to the R2D transmission or the D2R transmission needs to be transmitted within a preset time interval. The same as the definition of the foregoing offset information, which will not be repeated here.

[0120] It should be noted that the second time granularity, the third time granularity, the fourth time granularity, the fifth time granularity, and the sixth time granularity are all time granularity units, for example, OFMD symbol, time slot, OOK chip, bit, etc.

[0121] In an embodiment, the frequency domain resource information of the D2R transmission and / or the R2D transmission indicates frequency domain resource information of the current control information transmission, frequency domain resource information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or frequency domain resource information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the frequency domain resource information includes: frequency resources occupied by the transmission, start position information of the frequency resources, frequency resource mapping mode, transmission carrier frequency information, or subcarrier spacing information.

[0122] It should be noted that the indication object of the frequency domain resource information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the aforementioned transmission block information, which will not be described here again.

[0123] The frequency resource occupied by the transmission includes a transmission bandwidth and / or a guard bandwidth. The transmission bandwidth refers to the size of the frequency resource occupied when the signal is transmitted. The guard bandwidth does not place the signal therein, and is used to separate the IoT signal and other signals.

[0124] The starting position information of the frequency domain resource includes absolute starting position information and / or frequency offset information.

[0125] The absolute starting position information can be the P1st Hz, the P2nd RE, or the P3rd RB. P1, P2, and P3 are determined according to actual conditions. RE (Resource Element) is the smallest physical resource unit in a communication network, and one resource element corresponds to one subcarrier and one symbol period. RB (Resource Block) is a basic frequency domain resource scheduling unit in a communication network, and one resource block includes 12 subcarriers and is composed of 12 REs.

[0126] The frequency offset information is an offset relative to the previous frequency. For example, the offset is defined as offset, and the target frequency position is the sum of the current frequency position information and offset.

[0127] The frequency resource mapping manner includes continuous frequency resource mapping or segmented continuous frequency resource mapping. The continuous frequency resource mapping means that the allocated frequency resource is continuous. The segmented continuous frequency resource mapping means that the allocated frequency resource is continuous in each part. For example, the allocated frequency resource takes into account the guard bandwidth, and therefore the frequency resource of the non-guard bandwidth is indicated, that is, the allocated frequency resource is segmented and continuous.

[0128] The carrier frequency information of the transmission is used to represent the carrier frequency size of the current transmission.

[0129] The subcarrier spacing information is used to represent the subcarrier spacing of the current transmission, and can directly indicate the subcarrier spacing numerical information or indicate the numerology information. The subcarrier spacing information can include at least one of 3.75 KHz, 7.5 KHz, 15 KHz, 30 KHz, 60 KHz, 120 KHz, and 240 KHz. Numerology refers to a parameter set, which can include subcarrier spacing, symbol length, CP length, and the like.

[0131] It should be noted that the indication object of the candidate resource information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the transmission block information in the above-mentioned embodiments, which will not be described here.

[0132] The candidate resource refers to a candidate resource selected from all available resources according to certain rules or algorithms in a communication system, for subsequent communication processes (such as data transmission, signal transmission, etc.).

[0133] The selection rules or selection algorithms of the candidate resource can include resource pool-based selection, channel condition-based sorting, or transmission rank-based determination, etc. For example, the resource pool-based selection can monitor the availability of resources in the resource pool, and select candidate resources from the resource pool according to the preset configuration information. The channel condition-based sorting can perform channel quality evaluation on the resources in the resource pool, and sort the resources according to the channel quality evaluation results, and select the top 5 resources in the channel quality sorting as the candidate resources. The transmission rank-based determination can select a resource group that meets the transmission rank requirement from the candidate resource set as the candidate resource according to the transmission rank requirement, and the transmission rank is used to represent the parallel data stream data or antenna configuration in the transmission process.

[0134] In an embodiment, the candidate resource at least includes a resource set of time domain resources or frequency domain resources, and the set of multiple candidate resources is referred to as a candidate resource set. The resource type of the candidate resource and the position of the candidate resource in the candidate resource set can be recorded in the candidate resource set, wherein the position of the candidate resource in the candidate resource set can be represented by the ordinal of the candidate resource. For example, the A1th candidate resource is the A1th candidate resource in the candidate resource set.

[0135] The maximum number information of the candidate resource refers to the maximum number of candidate resources in the candidate resource set, for example, the maximum number of candidate resources in the candidate resource set is A2.

[0136] The available number information of the candidate resource represents the number of candidate resources in the candidate resource set that are in an active state or available for selection, for example, the available number of candidate resources includes A3.

[0137] The ordinal A1, the maximum number of candidate resources A2, and the available number of candidate resources A3 of the candidate resources can be valued according to actual situations, and the present disclosure does not make specific limitations thereon.

[0139] It should be noted that the indication object of the frequency hopping indication information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the transmission block information in the foregoing embodiments, which will not be described herein again.

[0140] The frequency hopping technology refers to frequency shift keying with a pseudo-random code sequence, which is a technology for expanding the spectrum by constantly changing the carrier frequency.

[0141] The frequency hopping enabling information is used to indicate whether the D2R transmission and / or the R2D transmission supports frequency hopping. For example, when the frequency hopping enabling information is enabled, it indicates that the D2R transmission and / or the R2D transmission supports frequency hopping; and when the frequency hopping enabling information is not enabled, it indicates that the D2R transmission and / or the R2D transmission does not support frequency hopping.

[0142] The frequency hopping times information is used to indicate the frequency hopping times of the D2R transmission and / or the R2D transmission. When the frequency hopping technology is used for communication, the transmission signal bandwidth can be divided into multiple sub-frequencies, and the frequency of the receiving and transmitting end is constantly changed according to the pre-agreed frequency. The parameters of the frequency hopping signal can include the frequency hopping period and the hopping speed. The frequency hopping times are calculated according to the frequency hopping period and the hopping speed.

[0143] In one embodiment, the timeline information of the D2R transmission and / or the R2D transmission indicates the time interval between the current control information transmission and the indicated D2R transmission and / or R2D transmission, or the time interval between the indicated D2R transmission and / or R2D transmission and the next potential D2R transmission and / or D2R transmission, and the timeline information includes at least one of time interval information, time interval size, and time interval characteristics.

[0144] The indication object of the timeline information of the D2R transmission and / or the R2D transmission is the time interval of the D2R transmission and / or the R2D transmission. The D2R transmission and / or the R2D transmission can be D2R transmission and R2D transmission, or R2D transmission and D2R transmission, or twice D2R transmission or twice R2D transmission. The twice D2R transmission or the twice R2D transmission can be continuous or discontinuous.

The minimum time interval can be a time interval from a last time granularity of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the target D2R transmission, or a time interval from a last time granularity of a postamble of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the target D2R transmission.

[0146] In one embodiment, the time interval information includes a maximum time interval between the R2D transmission and the subsequent D2R transmission. The maximum time interval can be a time interval from a last time granularity of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the target D2R transmission, or a time interval from a last time granularity of a postamble of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the target D2R transmission.

[0147] In one embodiment, the time interval information includes a minimum time interval between the D2R transmission and the subsequent R2D transmission. The minimum time interval can be a time interval from a last time granularity of the D2R transmission (e.g., a PDRCH transmission) to a first time granularity of the target R2D transmission, or a time interval from a last time granularity of a postamble of the D2R transmission (e.g., a PDRCH transmission) to a first time granularity of the target R2D transmission.

[0148] In one embodiment, the time interval information includes a maximum time interval between the D2R transmission and the subsequent R2D transmission. The maximum time interval can be a time interval from a last time granularity of the D2R transmission (e.g., a PDRCH transmission) to a first time granularity of the target R2D transmission, or a time interval from a last time granularity of a postamble of the D2R transmission (e.g., a PDRCH transmission) to a first time granularity of the target R2D transmission.

[0149] In one embodiment, the time interval information includes a minimum time interval between two R2D transmissions. The minimum time interval can be a time interval from a last time granularity of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the next R2D transmission, or a time interval from a last time granularity of a postamble of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of the next R2D transmission.

[0150] It should be noted that the two R2D transmissions can be consecutive R2D transmissions, or can be discontinuous. For example, the time interval between the two R2D transmissions is the time interval of the first R2D transmission and the third R2D transmission. Preferably, the time interval of the two R2D transmissions can be the time interval of the consecutive R2D transmissions, i.e. the time interval of the first R2D transmission and the second R2D transmission.

[0151] In an embodiment, the time interval information includes: the maximum time interval between the two R2D transmissions. The maximum time interval can be the time interval from the last time granularity (e.g. PRDCH transmission) of the trailer synchronization code of the R2D transmission (e.g. PRDCH transmission) to the first time granularity of the next R2D transmission.

[0152] It should be noted that the two R2D transmissions can be consecutive R2D transmissions, or can be discontinuous. For example, the time interval between the two R2D transmissions is the time interval of the first R2D transmission and the third R2D transmission. Preferably, the time interval of the two R2D transmissions can be the time interval of the consecutive R2D transmissions, i.e. the time interval of the first R2D transmission and the second R2D transmission.

[0153] In an embodiment, the time interval information includes: the minimum time interval between the two D2R transmissions. The minimum time interval can be the time interval from the last time granularity (e.g. PDRCH transmission) of the D2R transmission to the first time granularity of the next D2R transmission, and can also be the time interval from the last time granularity of the trailer synchronization code of the D2R transmission (e.g. PDRCH transmission) to the first time granularity of the next D2R transmission.

[0154] It should be noted that the time interval between the two D2R transmissions can be different D2R time interval requirements, for example, in a multi-access system, it can be the time interval requirement between the D2R transmission of the first Internet of Things device and the D2R transmission of the second Internet of Things device, or the time interval requirement between the D2R transmission of the first Internet of Things device and the D2R transmission of the third Internet of Things device, used to express the minimum distance between the two Internet of Things devices. Preferably, it is the time interval of the first D2R transmission and the second D2R transmission of the same Internet of Things device.

[0155] In an embodiment, the time interval information comprises: a maximum time interval between two D2R transmissions. The maximum time interval can be a time interval from a last time granularity of a preamble of a D2R transmission (e.g., a PDRCH transmission) to a first time granularity of a next D2R transmission, or a time interval from a last time granularity of a postamble of a D2R transmission (e.g., a PDRCH transmission) to a first time granularity of a next D2R transmission.

[0156] It should be noted that the time interval between two D2R transmissions can be a time interval requirement between different D2R transmissions, for example, in a multi-access system, it can be a time interval requirement between a first D2R transmission of a first IoT device and a D2R transmission of a second IoT device, or a time interval requirement between a first D2R transmission of a first IoT device and a D2R transmission of a third IoT device, for expressing the maximum interval between two IoT device transmissions. Preferably, it is a time interval between a first D2R transmission and a second D2R transmission of the same IoT device.

[0157] It should be noted that the meanings of the maximum time interval and the minimum time interval in the above time interval information are only examples provided for illustrating the embodiments of the present disclosure, and should not be regarded as limiting the protection scope of the present disclosure. According to actual needs, other combinations of parameters and transformed forms can also be within the protection scope of the present disclosure, for example, a time interval from a first time granularity of a preamble of the R2D transmission (e.g., a PRDCH transmission) to a first time granularity of a target D2R transmission, which is not specifically limited by the present disclosure.

[0158] The time interval size is used to represent the number of time granularities occupied by the time interval, for example, the time interval size is B time granularities.

[0159] The characteristics of the time interval can be divided into time intervals according to different types of IoT devices, time intervals according to different types of services, time intervals according to different types of commands, or time intervals according to different use cases.

[0160] It should be noted that the values of the above time intervals according to different types can be the same or different, which is not limited by the present disclosure.

[0161] In an embodiment, the time granularity information of the D2R transmission and / or the R2D transmission indicates time granularity information of the current control information transmission, time granularity information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or time granularity information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the time granularity information comprises a time granularity value and a time granularity unit.

[0162] It should be noted that the indication object of the time granularity information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the transmission block information in the foregoing embodiments, and details are not repeated here.

[0163] The time granularity unit includes at least one of an OFDM frame, an OFDM subframe, an OFDM symbol, an OFDM slot, a microsecond, a sampling point, an OOK chip, a bit, a PRDCH chip, a PRDCH symbol, a PRDCH slot, a PRDCH sampling point, a PRDCH bit, a PDRCH chip, a PDRCH symbol, a PDRCH slot, a PDRCH sampling point, a PRDCH bit, an R2D chip, an R2D symbol, an R2D slot, an R2D sampling point, an R2D bit, a D2R chip, a D2R symbol, a D2R slot, a D2R sampling point, and a D2R bit.

[0164] The time granularity value is used to represent the number of time granularities occupied by the control information. For example, the time granularity value is C time granularities.

[0165] The time granularity unit is a basic unit of time, and the time granularity unit can be any one of the above basic units or can include a plurality of the above basic units.

[0166] When the time granularity unit includes a plurality of basic units, the time granularity unit can include a plurality of identical basic units, for example, the time granularity unit includes two chips; or the time granularity unit can include different basic units, for example, the time granularity unit includes a combination of one chip and one OFDM symbol. For example, a time granularity unit is defined as the sum of the duration of one low-level chip and one high-level chip.

[0167] In the NR communication, a frame structure is composed of a frame, a subframe, a slot (Slot), and a symbol. One frame has a length of 10 ms, and one frame includes 10 subframes, each subframe has a length of 1 ms, and the lengths of the slot and the symbol can be flexibly defined according to the subcarrier spacing.

[0168] For the slot, it can also be referred to as a time unit, such as the OFDM slot, the PRDCH slot, the PDRCH slot, the R2D slot, the D2R slot, and the like. In the NR system, there are five optional subcarrier spacings, and accordingly, the number of slots in each subframe depends on the parameter μ, which has five values, 0-4. When μ=0, the number of slots or subframes is 1, and the length of each slot is 1 ms; when μ=1, the number of slots or subframes is 2, and the length of each slot is 0.5 ms; when μ=2, the number of slots or subframes is 4, and the length of each slot is 0.25 ms; when μ=3, the number of slots or subframes is 8, and the length of each slot is 0.125 ms; and when μ=4, the number of slots or subframes is 16, and the length of each slot is 0.0625 ms.

[0169] Symbol, also known as Symbol, is a short form of time domain symbol. Time domain symbols can also be named in combination with other multiple access methods. The length of the time domain symbol can be different for different subcarrier spacings. For example, the above-mentioned OFDM symbol, R2D symbol, D2R symbol, etc. Generally, each slot includes 14 OFDM symbols.

[0170] Sampling points are a series of discrete sampling points obtained from the transmitted or received waveform by a node such as a base station or an Internet of Things device according to a certain time interval, which is the smallest unit of processing for the transmitting or receiving end. PRDCH sampling points, PDRCH sampling points, R2D sampling points, D2R sampling points, etc. can be divided according to the purpose of the sampling points.

[0171] Chips are used to represent the time resolution of a signal, and the chip rate is the number of chips transmitted per second, which determines the highest rate at which the system can process signals. PRDCH chips, PDRCH chips, R2D chips, D2R chips, OOK chips, etc. can be divided according to the purpose of the chips.

[0172] The definition of microsecond μs can reuse the existing international standard definition. The time granularity of microsecond is mainly used to represent a certain time granularity defined as AAμs, where AA is a specific value. For example, the time granularity of PDRCH is defined as 44.4μs.

[0173] Bit, also known as bit, is used to represent the bit duration of each bit in a R2D or D2R transmission. For example, the R2D transmission duration is 2 bits, which means the duration of the R2D transmission is 2 bit durations.

[0174] In one embodiment, the transmission rate information of the D2R transmission and / or the R2D transmission indicates the transmission rate information of the current control information transmission, the transmission rate information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or the transmission rate information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information. The transmission rate information includes at least one of the following information: data rate information; bit rate information; chip rate information; M value information.

[0175] The indication object of the transmission rate information of the D2R transmission and / or the R2D transmission is similar to the determination method of the indication object of the transmission block information in the foregoing embodiment, which will not be described here.

[0176] Data rate information is used to represent the speed of data transmission per unit time. For example, the amount of information transmitted per unit time on the channel of the D2R transmission and / or the R2D transmission can be measured in bits.

[0177] Bit rate information, also referred to as bit rate, is used to represent the number of bits transmitted through a channel per unit of time, and directly determines the speed and efficiency of data transmission.

[0178] Chip rate information is used to represent the number of chips transmitted per unit of time.

[0179] M value information is used to represent the amount of information that can be carried by each chip. The M value is the number of different discrete values that a chip or symbol can take. For example, the M value includes a specific integer from 1 to 16. Preferably, the M value is at least one of 1, 2, 4, 8, and 16. The M value affects the transmission rate and efficiency of data.

[0180] In one embodiment, the Cyclic Prefix (CP) information of the D2R transmission and / or the R2D transmission indicates the CP information of the current control information transmission, the CP information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or the CP information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information. The CP information includes CP length information, CP type information, and / or CP enable information.

[0181] The indication object of the CP information of the D2R transmission and / or the R2D transmission is similar to the determination method of the indication object of the transmission block information in the foregoing embodiments, which will not be described here.

[0182] The Cyclic Prefix (CP) can copy the signal at the tail of the OFDM symbol to the head, thereby reducing or eliminating the inter-symbol interference caused by multipath propagation.

[0183] The CP type information can include a normal cyclic prefix and an extended cyclic prefix. For example, the length of the normal cyclic prefix is 4.7 μs, and the length of the extended cyclic prefix is 16.67 μs.

[0184] The CP length information represents the length value of the cyclic prefix. When all CP lengths are the same, the CP length information can indicate the CP length size of the current transmission, for example, B time granularities. When some CP lengths are different, the CP length information indicates the CP length value of the CP length that is different and / or the remaining length that is the same. The CP length information can also indicate the number of CP lengths that are the same and / or the number of CP lengths that are different.

[0185] The CP enable information is used to represent whether the current transmission adds a CP. For example, when the CP enable information is 1, it represents that the current transmission adds a CP, and when the enable information is 0, it represents that the current transmission does not add a CP.

[0186] In one embodiment, the synchronization information of the D2R transmission and / or the R2D transmission indicates synchronization information of the current control information transmission, synchronization information of the D2R transmission and / or the R2D transmission scheduled by the current control information, or synchronization information of the D2R transmission and / or the R2D transmission after the D2R transmission and / or the R2D transmission scheduled by the current control information, and the synchronization information includes at least one of the following information: generation density of the intermediate synchronization code, generation structure of the intermediate synchronization code.

[0187] The indication object of the synchronization information of the D2R transmission and / or the R2D transmission is determined in the same manner as the indication object of the transmission block information in the foregoing embodiments, which will not be described herein again.

[0188] The generation density of the intermediate synchronization code refers to the number of time granules per insertion of an intermediate synchronization code. The generation density of the intermediate synchronization code is based on insertion of an intermediate synchronization code at a preset number of time granules, and the preset number can be determined according to actual needs and is preconfigured in the second device. The preset number is within a preset range, for example, the preset number is between 1 and 20.

[0189] The preset number is calculated starting from the first time granule of the preceding synchronization code, calculated starting from the last time granule of the preceding synchronization code, or calculated starting from the first time granule of the R2D transmission or the D2R transmission after the preceding synchronization code.

[0190] As shown in FIG. 3, the preset number is 4, and when the calculation starts from the first time granule of the preceding synchronization code, the intermediate synchronization code can be inserted at the 5th time granule, the 10th time granule, the 15th time granule, and the like.

[0191] For example, the preset number is 4, and when the calculation starts from the last time granule (for example, the 15th time granule) of the preceding synchronization code, the intermediate synchronization code can be inserted at the 20th time granule, the 25th time granule, and the like.

[0192] The calculation of the preset number starting from the first time granule of the R2D transmission or the D2R transmission after the preceding synchronization code can refer to the foregoing examples, which will not be described herein again.

[0193] The generation structure of the intermediate synchronization code includes that all the inserted intermediate synchronization codes are the same, or that the intermediate synchronization code performing a specific function among the inserted at least one intermediate synchronization code has a different generation manner from the target intermediate synchronization code.

[0194] It should be noted that at least one intermediate synchronization code can be inserted in the transmission. When multiple intermediate synchronization codes are inserted, the multiple intermediate synchronization codes are all the same, for example, the intermediate synchronization code is only generated by a sequence, or the intermediate synchronization code is composed of other information, or the composition of the intermediate synchronization code is jointly constituted by the sequence and other information. The other information can be clock acquisition information and the like.

[0195] In one embodiment, when multiple intermediate synchronization codes are inserted, at least one intermediate synchronization code performing a specific function can be included in the multiple intermediate synchronization codes, the at least one intermediate synchronization code performing the specific function is different from the generation mode of the target synchronization code, the target synchronization code is the intermediate synchronization code in the multiple intermediate synchronization codes except the at least one intermediate synchronization code performing the specific function, and the specific function can include measurement, channel estimation, and the like.

[0196] For example, the intermediate synchronization code performing the specific function can be generated once every B1 time granularity.

[0197] As shown in FIG. 4, when the first time granularity of the preamble synchronization code is taken as the starting point for calculation, the intermediate synchronization codes can be inserted at the positions of the 5th time granularity, the 10th time granularity, the 15th time granularity, the 20th time granularity, and the like, respectively, wherein the positions corresponding to the 10th time granularity and the 20th time granularity are inserted with the intermediate synchronization codes performing the specific function.

[0198] For example, the intermediate synchronization code performing the specific function can be generated once every B1 time granularity.

[0199] It should be noted that other intermediate synchronization code generation rules can also be used to generate the intermediate synchronization code performing the specific function, and the present disclosure is not limited in this regard.

[0209] The measurement interval, also referred to as the measurement period, is, for example, performed at an X time granularity, or is determined according to the period of the preamble synchronization code, the intermediate synchronization code, or the postamble synchronization code and the actual enabling condition.
