[0086] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work, fall within the scope of protection of the present disclosure.

[0087] The relative arrangement, numerical expressions, and numerical values of the components and steps set forth in the embodiments are not limiting on the scope of the present disclosure, unless otherwise specifically stated.

[0088] It should be understood that the sizes of the various parts shown in the drawings are not drawn in accordance with the actual proportion relationship for the convenience of description.

[0089] The technology, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification when appropriate.

[0090] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0091] It should be noted that similar reference numbers and letters represent similar items in the following drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0092] The inventors notice that, considering the low power consumption, low cost and low complexity characteristics of the Internet of Things device, the environmental Internet of Things system needs to design a dedicated transmission mode and transmission format to realize the scheduling of the Internet of Things device by the base station side, so that the Internet of Things device obtains the transmission resource and the transmission command information, and completes the transmission process. The 3rd Generation Partnership Project (3GPP) organization has not yet designed any timing and time relationship.

[0093] Accordingly, the present disclosure provides a communication method which can design the time relationship of the Internet of Things device in the transmission process.

[0094] FIG. 1 is a flowchart of a communication method according to an embodiment of the present disclosure. In some embodiments, the following communication method is performed by the Internet of Things device, including steps 11-12.

[0095] Step 11, receiving time domain control information sent by a network side device.

[0096] It should be noted that the time domain control information includes at least one of time relationship information, time domain resource information, time interval information and timing scheduling information.

[0097] In step 12, based on the time domain control information, D2R (device to reader) transmission is performed with the network side device at a first time.

[0098] It should be noted that the D2R transmission includes at least one of PDRCH (Physical Device to Reader Channel, physical layer transmission channel on D2R link), D2R control signal, synchronization signal and reference signal.

[0099] In some embodiments, the first time includes at least one of the following:

[0100] 1) The maximum time interval T from the last time granularity of the last R2D (reader to device) transmission to the first time granularity of the D2R transmission R2D_max ;

[0101] 2) The minimum time interval T from the last time granularity of the last R2D transmission to the first time granularity of the D2R transmission R2D_min ;

[0102] It should be noted that, due to the inaccuracy of timing of the IoT device, the time relationship between the end of the R2D transmission and the start of the D2R transmission cannot be accurately determined, and therefore the maximum time interval T R2D_max and the minimum time interval T R2D_min in the time relationship are configured to determine the range of the interval in which the time relationship may be located.

[0103] 3) The time interval T R2D from the last time granularity of the end of the previous R2D transmission to the first time granularity of the D2R transmission;

[0104] It should be noted that, due to the current high-layer configuration or indication information not considering the error impact caused by timing inaccuracy, only the behavior of the IoT device is defined, and therefore the first time can be indicated as the time interval T R2D from the end of the R2D transmission to the start of the D2R transmission.

[0105] 4) The minimum time interval T D2R_D2R_min from the last time granularity of the end of the previous D2R transmission to the first time granularity of the D2R transmission;

[0106] 5) The maximum time interval T D2R_D2R_max from the last time granularity of the end of the previous D2R transmission to the first time granularity of the D2R transmission;

[0107] It should be noted that, in addition to the most common scenario of receiving control information of R2D and then feeding back D2R according to the control information, the IoT device can also have a case of two consecutive D2R transmissions. In this case, the minimum time interval T D2R_D2R_min and the maximum time interval T D2R_D2R_max in the time relationship are configured to determine the range of the interval in which the time relationship may be located.

[0108] 6) The time interval T D2R_D2R from the last time granularity of the end of the previous D2R transmission to the first time granularity of the D2R transmission;

[0109] It should be noted that, in addition to the most common scenario of receiving control information of R2D and then feeding back D2R according to the control information, the IoT device can also have a case of two consecutive D2R transmissions. Due to the current high-layer configuration or indication information not considering the error impact caused by timing inaccuracy, only the behavior of the IoT device is defined, and therefore the first time can include the time interval T D2R_D2R from the end of the R2D transmission to the start of the D2R transmission.

[0110] 7) the maximum time interval T from the first time granularity of the start of the transmission of the carrier CW to the first time granularity of the D2R transmission CW_D2R_max ;

[0111] 8) the minimum time interval T from the first time granularity of the start of the transmission of the carrier CW to the first time granularity of the D2R transmission CW_D2R_min ;

[0112] It should be noted that if the IoT device can be fully controlled by the reader, can wake up in the target time interval, and can be fully charged for a D2R transmission, the reader needs to send the CW carrier at a controllable time to let the IoT device charge first, and after being fully charged, the IoT device can perform a D2R transmission without delay or with a short delay, avoiding the problem that the IoT device wakes up to prepare to send a D2R transmission and runs out of power due to too long waiting time.

[0113] 9) the time interval T from the first time granularity of the start of the transmission of the carrier CW to the first time granularity of the D2R transmission CW_D2R .

[0114] It should be noted that since the current high-layer configuration or indication information does not consider the error caused by timing inaccuracy, only the behavior of the IoT device is defined, so the first time can include the time interval T from the first time granularity of the start of the transmission of the carrier CW to the first time granularity of the D2R transmission CW_D2R .

[0115] In some embodiments, the first time is predefined, preconfigured, high-layer configured, or physically indicated.

[0119] For example, T R2D_max is a positive integer, and the value range is 200 μs to 300 μs.

[0126] 2.3) multiple values configured or indicated directly.

[0127] For example, multiple values of T R2D_max are all set to 200μs~300μs.

[0128] In some embodiments, T R2D_max includes multiple values, meaning that the higher layer configures multiple values, and a value is determined from the multiple values according to some configuration of system parameters, etc. by a pre-defined rule, or multiple values are configured directly for the IoT device to select by itself. If 1 value is configured, the signaling overhead is small, the overall mechanism is relatively simple, and it is in line with the characteristics of IoT devices. If multiple values are configured, it has better flexibility, and the overall performance will be better.

[0129] In some embodiments, the minimum time interval T R2D_min includes at least one of the following:

[0130] 1) a value.

[0583] The disclosure will be described below through specific examples. It should be noted that the device in the text means an Internet of Things device.

[0584] Embodiment one:

[0585] The time interval T from the last time granularity of the previous R2D transmission to the first time granularity of the D2R transmission R2D As shown in FIG. 3.

[0586] As shown in Fig. 3, the next D2R transmission for the R2D transmission can start at the earliest and the latest two possible time instants, starting from the last time instant of the R2D transmission. The time interval between the earliest time instant of the D2R transmission and the starting time instant is considered as T R2D_min , and the time interval between the latest time instant of the D2R transmission and the starting time instant is considered as T R2D_max， . The starting time instant of the D2R transmission will be located between [T R2D_min , T R2D_max ]. This scheme is generally used in the scenario that there is an R2D control signaling, and the control signaling triggers the D2R transmission.

[0587] Embodiment Two:

[0588] The time interval T R2D from the last time granularity of the previous R2D transmission to the first time granularity of the D2R transmission, as shown in Fig. 4.

[0589] As shown in Fig. 4, compared with Embodiment One, the earliest and the latest two possible time instants are no longer defined, but the value of T R2D is directly configured or indicated to inform the device of the theoretical accurate time instant of the D2R transmission, so as to avoid too frequent collision when multiple devices transmit simultaneously. This scheme is generally used in the scenario that there is an R2D control signaling, and the control signaling triggers the D2R transmission.

[0590] Embodiment Three:

[0591] The time interval T D2R_D2R from the last time granularity of the previous D2R transmission to the first time granularity of the D2R transmission, as shown in Fig. 5.

[0592] As shown in Fig. 5, the next D2R transmission can start at the earliest and the latest two possible time instants, starting from the last time instant of the D2R transmission. The time interval between the earliest time instant of the D2R transmission and the starting time instant is considered as T D2R_D2R_min , and the time interval between the latest time instant of the D2R transmission and the starting time instant is considered as T D2R_D2R_max， . The starting time instant of the D2R transmission will be located between [T D2R_D2R_min , T D2R_D2R_max ]. This scheme is generally used in the scenario that there is an R2D transmission, and due to the long decoding time required for decoding the R2D transmission, the device cannot make a reply within the predetermined time range, and thus sends multiple D2R transmissions to express that the device is still processing and will make a delayed reply.

[0593] Embodiment Four:

[0594] The time interval T from the last time granularity of the previous D2R transmission to the first time granularity of this D2R transmission D2R_D2R As shown in FIG. 6.

[0595] As shown in FIG. 6, compared with the embodiment three, instead of defining the earliest and latest two possible time instants, the exact time instant that theoretically needs to be consumed between two D2R transmissions is directly configured or indicated, to inform the device the exact time instant at which the D2R transmission 2 should be sent, to avoid frequent collisions caused by multiple devices delaying the reply.

[0596] Embodiment five:

[0597] The time interval information T from the first time granularity of the CW to the first time granularity of this D2R transmission CW_D2R As shown in FIG. 7.

[0598] As shown in FIG. 7, this time interval is mainly used to consider how long the CW should be sent in advance of the D2R, so if the time at which the CW ends is still used as the starting time instant, it will become a requirement that the D2R transmission should be transmitted within a certain time after the CW transmission is completed. This is unreasonable, because the most ideal state is to immediately transmit the D2R after the CW completes the charging of the device, so the time interval between the CW and the D2R transmission should be as short as possible to ensure the continuity of the D2R transmission, but if it is too short, it will cause the base station side to transmit a segment of the CW for a long time, causing energy waste and potential interference, so this index is designed.

[0599] The time interval length from the time instant of the earliest D2R transmission to the starting time instant of the CW is considered to be T CW_D2R_min The time interval length from the time instant of the latest D2R transmission to the starting time instant of the CW is considered to be T CW_D2R_max， The time interval between the CW and the R2D will be located between [T CW_D2R_min , T CW_D2R_max ].

[0600] Embodiment six:

[0601] The time interval information T from the first time granularity of the CW to the first time granularity of this D2R transmission CW_D2R As shown in FIG. 8.

[0602] As shown in FIG. 8, the current time interval is mainly used to consider how long the CW should be sent in advance D2R, so if the time when the CW ends is still used as the starting time, it will become a requirement that the D2R transmission should be transmitted within a certain time after the CW transmission is completed. This is unreasonable because the most ideal state is to immediately transmit D2R after the CW completes the charging of the device, so the time of the CW and the D2R transmission should be as short as possible to ensure the continuity of the D2R transmission, but if it is too short, it will cause the base station side to transmit the CW for a period of time, resulting in energy waste and potential interference, so the index is designed.

[0603] Unlike embodiment five, embodiment six does not define the earliest sending and latest sending time, but instead configures or indicates an accurate value through the network side to ensure that the CW carrier arrives at the device side as soon as possible. This way is more efficient, but requires more accurate and complex signaling interaction.

[0604] Embodiment seven:

[0605] T R2D may be composed as shown in FIG. 9.

[0606] As shown in FIG. 9, T R2D may be composed of five parts, first of all, there must be a transmission delay, which objectively exists and is the main component of T R2D . Thus, this part of the delay can be pre-defined or pre-configured, or can be individually configured according to the capabilities of the device or the results of the measurement to meet the accuracy of individual transmission and avoid excessive transmission delay. After experiencing the transmission delay, the R2D transmission is received by the device, at which time there can be a device processing delay for decoding the R2D data. However, it can also not be separately defined and configured, but rather be considered in the sending preparation delay, i.e., not considering this part of the delay separately. The third part is the D2R preparation delay, which mainly refers to the time that must be waited after receiving the information to before the corresponding R2D transmission is sent, including R2D command parsing and preparation of corresponding information based on the next D2R transmission. If there is no carrier waiting delay, it can also include the processing time of modulation. The fourth part is the carrier waiting delay, which is used in scenarios where the CW carrier has not been transmitted or the device is in a charging state, resulting in a scenario where the CW needs to be waited for. This delay can be included in the D2R transmission preparation delay and not be separately defined, or it can be separately configured. The fifth part is the modulation time, which mainly depends on the fourth part. In the case where the fourth part is not separately defined, the fifth part is also not separately defined, but is entirely included in the preparation time; if the fourth part is separately defined or configured, the corresponding fifth part delay also needs to be separately defined or configured.

[0607] Embodiment Eight:

[0608] T D2R_D2R The composition of T

[0609] As shown in FIG. 10, the composition of T D2R_D2R does not involve the transmission latency of R2D and the processing latency of R2D, so it only includes the sending preparation latency, the carrier waiting latency and the modulation latency. If the carrier can arrive in advance or on time, it can not need to be configured separately.

[0610] Embodiment Nine:

[0611] T CW_D2R The composition of T

[0612] As shown in FIG. 11, in order to define the time advance relative to the D2R transmission, the time advance information of the CW carrier relative to the R2D transmission can be calculated, so that if the time needed for the CW to be advanced relative to the target D2R transmission needs to be calculated, after T CW_D2R is obtained, the time advance relative to the D2R transmission can be obtained through the time length of R2D and the value of T R2D , and the calculation method is: the time advance relative to the R2D transmission + the duration length of R2D + T R2D . After obtaining this time information, it can be ensured that the D2R transmission does not need to wait for a long time CW carrier, or can directly transmit.

[0613] Embodiment Ten:

[0614] T CW_D2R The composition of T

[0615] As shown in FIG. 12, in order to define the time advance relative to the D2R transmission, the time advance information of the CW carrier relative to the R2D transmission when received on the device side can be calculated, so that if the time needed for the CW to be advanced relative to the target D2R transmission needs to be calculated, after T CW_D2R is obtained, the time advance relative to the D2R transmission can be obtained through the time length of R2D and the value of T R2D . Considering that when receiving the R2D transmission, it can be necessary to consider pre-charging to activate the device, the calculation method is: the time advance relative to the R2D transmission + the duration length of R2D + the sending preparation time, or the time advance relative to the D2R transmission + the R2D charging time + the duration length of R2D + the sending preparation time. After obtaining this time information, it can be ensured that the D2R transmission does not need to wait for a long time CW carrier, or can directly transmit.

[0616] Embodiment Eleven:

[0617] T CW_D2R The composition of the device is shown in FIG. 13.

[0618] As shown in FIG. 13, in order to define the time advance relative to the D2R transmission, the time advance information of the CW carrier relative to the D2R transmission can be calculated. Considering that the advance charging may need to be considered when the D2R transmission, the calculation method is: the time advance relative to the D2R transmission, or the time advance relative to the D2R transmission + R2D charging time. After obtaining this time information, it can be ensured that the D2R transmission does not need to wait for a long time for the CW carrier, or can directly transmit.
