Description

Signaling method and apparatus TECHNICAL FIELD

[0001] The present application relates to the field of communication technology. BACKGROUND

[0002] From the early era of 2G system to 4G system, the main service object of cellular mobile communication system is mobile terminal equipment held by people. With the rapid development of mobile Internet and Internet of Things, since the late era of 4G system, the application scenarios of Internet of Things considered and supported in the evolution process of cellular mobile communication system are more and more rich, and more types of Internet of Things device terminal types are supported and landed in actual network deployment and service application, for example, enhanced Machine-Type Communication (eMTC) type terminal device, Narrow Band Internet of Things (NB-IoT) type terminal device, RedCap type terminal device, etc. With the diversification of Internet of Things terminal device types, cellular mobile system has stronger and stronger service ability for vertical industry.

[0003] However, in the field of massive Internet of Things devices, the huge number and lower cost of Internet of Things terminal devices are still a blank of cellular mobile communication system. In order to provide more robust, more reliable and more complete Internet of Things application solutions, how to support lower cost Internet of Things terminal devices in 3GPP cellular mobile system has become a problem to be solved.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application, and for the convenience of understanding by those skilled in the art. The above technical scheme cannot be considered as known to those skilled in the art only because it is described in the background section of the present application.

[0005] SUMMARY

[0006] Radio Frequency Identification (RFID) system is a solution for the field of Internet of Things (IoT) terminal devices with a large number and lower cost. The RFID system is widely used. The RFID system has the advantages of low tag cost and low price. The RFID tag is small in size, and has less restrictions on the size and material of the applied object, and thus is easy to apply to various object management and object tracking scenarios. Although the RFID tag is low in cost, the deployment cost and use cost of the RFID system are relatively high compared with the wide-area commercial network. In terms of deployment, the RFID system is usually locally deployed and dedicated, and the deployment cost is difficult to effectively allocate. In terms of use, if a manual handheld tag reader solution is adopted, the labor cost may become the main expense of the use cost and is difficult to reduce; if a dedicated RFID port or gateway is used for reading and management, the deployment cost will be significantly increased. In addition, the logical architecture of the RFID system is simple, and the wireless resource management is loose, for example, it is difficult to better coordinate the interference in the radio wave transmission, and thus the system capacity and spectrum use efficiency of the RFID system are generally low.

[0007] Compared with the existing RFID system, if the existing commercial mobile communication cellular network (such as the LTE system, the 5G NR system, etc.) can support the industry application of the tag type IoT terminal device, the deployment cost can be effectively reduced, and thus the deployment threshold of this type of IoT device is reduced. In addition, the existing commercial mobile communication cellular network (such as the LTE system, the 5G NR system, etc.) is much higher than the existing RFID system in terms of network security and wireless resource management effectiveness.

[0008] Taking the 5G system as an example, the 5G system can provide high security level authentication, network coordination and accurate and stable terminal device management mechanism, can safely and effectively reduce the labor cost in use, and thus reduce the use cost of this type of IoT, and can also optimize the network to improve the system capacity and spectrum use efficiency. The reduction of the deployment cost and the use cost can effectively promote the application of the tag type IoT terminal device in commercial management and industrial manufacturing, accelerate the digitalization process of the related industry, improve the production efficiency, and ultimately more effectively promote the social development.

[0009] As a new type of IoT terminal in the 5G system, the tag type IoT terminal device (Ambient IoT device, A-IoT device) is severely cost limited. The hardware capability of the device is obviously weaker than that of the ordinary smart phone and other existing cellular mobile communication system supported IoT type device. For example, the tag type IoT terminal device may not have a stable power supply (such as using environmental energy collection instead of a conventional battery), have a narrow bandwidth, have a limited precision of a crystal oscillator due to cost limitation, and have a limited signal processing capability.

[0010] In addition, due to limited device capability of Ambient IoT device (A-IoT device, referred to as device or terminal device for short), how to improve the coverage capability of Ambient IoT system is also a problem to be solved. In order to solve the problem, an intermediate node can be added between the gNB (network device) and the device (terminal device) to improve the coverage capability of the network. However, for the scene in which the intermediate node is needed in the topology structure, how to make the intermediate node know the time domain resource for sending a signal to the A-IoT device or receiving a signal from the A-IoT device is a key problem, so as to avoid the conflict between the signal transmitted and received by the intermediate node and the signal transmitted and received by the device, and further ensure that the signal transmitted by the network side can be received by the A-IoT device and the signal transmitted by the A-IoT device can be received by the network side.

[0015] The third signal is a signal sent by the first device to at least a first terminal device, and the fourth signal is a signal received by the first device from a second terminal device.

[0061] FIGS. 1A-1C are schematic diagrams of a communication system of the embodiments of the present application, which schematically illustrates the case taking the A-IoT device and the network device as examples. As shown in FIGS. 1A-1C, the communication system 100 can include a network device 101 and an A-IoT device 102. For simplicity, FIGS. 1A-1C only take one A-IoT device and one network device as examples for illustration, but the embodiments of the present application are not limited thereto.

[0062] The network device 101 can directly communicate with the A-IoT device 102, for example, as shown in FIG. 1A, directly sending signals to the A-IoT device 102 or directly receiving signals from the A-IoT device 102; the network device 101 can also send signals to the A-IoT device 102 or receive signals from the A-IoT device 102 through an intermediate node, for example, as shown in FIG. 1B, using the intermediate node 103 (which can be a forwarder or an IAB node or a UE or a relay, etc.) to send signals to the A-IoT device 102 or receive signals from the A-IoT device 102; the network device 101 can also send signals to the A-IoT device 102 or receive signals from the A-IoT device 102 with the help of the auxiliary node 103 (which can be a forwarder or an IAB node or a UE or a relay, etc.), for example, as shown in FIG. 1C.

In the embodiments of the present application, for the convenience of description, the intermediate node and the auxiliary node are collectively referred to as "first device", which can be the aforementioned "user equipment" or "terminal device", and the A-IoT device is collectively referred to as "terminal device", such as the "first terminal device" and "second terminal device" described below.

[0065] The various embodiments of the present application will be described below in conjunction with the accompanying drawings. These embodiments are only exemplary and not limiting to the present application.

[0066] Embodiments of the first aspect

[0067] The embodiments of the present application provide a signal sending method, which is described from the side of the terminal device.

[0068] FIG. 2 is a schematic diagram of a signal sending method according to an embodiment of the present application. As shown in FIG. 2, the method comprises:

[0069] 210, the first device receives a first signal from the network device, wherein the first signal at least includes time domain resource information related to the third signal and / or the fourth signal;

[0070] 220, the first device sends a second signal to the network device, wherein the second signal at least includes part or all of the fourth information bits carried by the fourth signal.

[0071] In the above embodiments, the third signal is a signal sent by the first device to at least the first terminal device, and the fourth signal is a signal received by the first device from the second terminal device.

[0072] It is worth noting that the above FIG. 2 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between the operations can be appropriately adjusted, and in addition, some operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above description, and the present application is not limited to the description of the above FIG. 2.

[0073] FIG. 3 is a schematic diagram of information interaction of the first device with the network device and the terminal device. As shown in FIG. 3, the first device 310 can receive a first signal from the network device 320, send a third signal to the first terminal device 330, receive a fourth signal from the second terminal device 340, and send a second signal to the network device 320. Optionally, as shown in FIG. 3, the first device 310 can also receive a fifth signal from the network device 320. The specific meanings of the first signal to the fifth signal will be described later. The third signal can be sent to more than one first terminal device 330.

[0074] In the example of FIG. 3, the first terminal device 330 and the second terminal device 340 are taken as the same terminal device, for example, the first terminal device 330 and the second terminal device 340 have the same device ID, but the present application is not limited thereto, and the first terminal device 330 and the second terminal device 340 can also be different terminal devices.

[0075] In the embodiments of the present application, the first device can be the intermediate node 103 in the scenario shown in FIG. IB, or the auxiliary node 103 in the scenario shown in FIG. 1C, for example, a repeater or an IAB node or a UE or a relay, etc., and the first terminal device and the second terminal device can be the terminal device 102 in the scenarios shown in FIGS. 1A to 1C, for example, an A-IoT device, which has a much lower capability than the first device.

[0076] According to the above embodiments, the time domain resource information related to the signal (the third signal) sent to the first terminal device and / or the time domain resource information related to the signal (the fourth signal) received from the second terminal device is carried by the signal (the first signal) from the network device, which solves the problem of which time domain resources the first device uses to send the signal (the third signal) to the first terminal device and / or which time domain resources the first device uses to receive the signal (the second signal) from the second terminal device, and improves the reliability of signal transmission and reception.

[0077] FIG. 4 is a schematic diagram of time domain resources of the first signal to the fourth signal. As shown in FIG. 4, the first signal and the fourth signal are signals received by the first device, the second signal and the third signal are signals sent by the first device, the first signal and the second signal are signals for communication between the first device and the network side, and the third signal and the fourth signal are signals for communication between the first device and the terminal device (device) side. In addition, in FIG. 4, the rectangular blocks represent the time domain resources of the signals. The relationship between the time domain resources of the signals will be described later.

[0078] In the example of FIG. 4, only the time-domain relationship between the signals is shown. In some examples, the first signal can also schedule multiple third signals or fourth signals, and in addition, the multiple fourth signals can also be a response of a third signal, and the like.

[0079] In the embodiments of the present application, for the convenience of description, the time-domain resource carrying the first signal is referred to as the first time-domain resource, the time-domain resource carrying the second signal is referred to as the second time-domain resource, the time-domain resource carrying the third signal is referred to as the third time-domain resource, and the time-domain resource carrying the fourth signal is referred to as the fourth time-domain resource.

[0080] In some embodiments, the time-domain resource related to the first signal is, for example, the first time-domain resource for carrying the first signal; the time-domain resource related to the second signal is, for example, the second time-domain resource for carrying the second signal, or the second reference time-domain resource for determining the second time-domain resource; the time-domain resource related to the third signal is, for example, the third time-domain resource for carrying the third signal, or the third reference time-domain resource for determining the third time-domain resource; and the time-domain resource related to the fourth signal is, for example, the fourth time-domain resource for carrying the fourth signal, or the fourth reference time-domain resource for determining the fourth time-domain resource.

[0081] In some embodiments, the time-domain resource (for example, the first time-domain resource, and / or, the second time-domain resource or the second reference time-domain resource, and / or, the third time-domain resource or the third reference time-domain resource, and / or, the fourth time-domain resource or the fourth reference time-domain resource) related to the first signal and / or the second signal and / or the third signal and / or the fourth signal can include at least one of the following:

[0082] The start of the time-domain resource;

[0083] The time-domain offset of the time-domain resource;

[0084] The duration of the time-domain resource;

[0085] The end of the time-domain resource;

[0086] The reference SCS of the time-domain resource;

[0087] The period of the time-domain resource.

[0088] In the above embodiments, regarding the start and / or end of the time-domain resource and the time-domain offset of the time-domain resource:

[0089] In some possible implementation, the start and / or end of the time domain resource is in units of frame and / or subframe and / or slot and / or symbol in the NR system; the time offset of the start and / or end of the time domain resource, i.e., the time domain offset of the time domain resource, can be indicated by physical layer signaling and / or MAC CE and / or RRC signaling, for example, can be frame offset and / or subframe offset and / or slot offset and / or symbol offset.

[0090] In one example, the start of the time domain resource is configured as slot offset and symbol offset. The slot where the second reference time domain resource and / or the third reference time domain resource and / or the fourth reference time domain resource is located is n, then the first device starts to send the third signal in the Kth slot after the slot n.

[0091] In the above example, the value of K is a positive integer greater than or equal to 0, which can be configured by RRC signaling or MAC CE or physical layer signaling, for example, the value range of K can be {0, 1, …, Kmax}, and the specific value of K can be indicated by RRC signaling or MAC CE or physical layer signaling;

[0092] In the above example, the Sth symbol in the slot n+K is the start and / or end of the second time domain resource and / or the third time domain resource and / or the fourth time domain resource. For example, by default, the first device starts the second time domain resource and / or the third time domain resource and / or the fourth time domain resource in the first symbol in the slot n+K. For another example, S is configured or indicated by RRC signaling or MAC CE or physical layer signaling, for example, the value range of S is {0, 1, …, 13}, and the above RRC signaling or MAC CE or physical layer signaling indicates that the specific value of S is one in the above value range. For another example, S is jointly indicated with the duration of the time domain resource, for example, S is determined by SLIV (Start and Length Indicator Value) mode, i.e., the corresponding index or value of SLIV is indicated, thereby the corresponding start symbol and the number of symbols or the length of duration can be determined.

[0093] In some other possible implementation, the start and / or end of the time domain resource is in units of absolute time T (for example, second, millisecond, microsecond, etc.).

[0094] In one example, T is a standard pre-agreed default value.

[0095] In another example, T is configured by the network side.

[0096] For example, T is a value configured by the network side based on the capability information reported by the UE. For example, the network device determines T based on a table related to UE capability, as shown in Table 1 below, and configures the value (ms) of T according to the class reported by the UE.

[0097] Table 1

[0098] For another example, T is a value directly configured by the network side. For example, the value range of T is {T1, T2, T3, …}, and the network device indicates that T can take one value in the above value range.

[0099] In yet another example, the first device determines the value of T according to a predefined UE capability class, such as the class in Table 1 above. It should be noted that in this example, the first device also needs to report capability information or a class corresponding to the capability, wherein the capability information reported by the first device at least includes the time required to process the first signal and the third signal, and / or the time required for the first device to switch the transceiver module or the antenna, etc.

[0100] In yet some possible implementation manners, the start and / or end of the time domain resource is in units of a new time unit, for example, in units of a new time unit different from the frame, subframe, slot, symbol defined in the NR system. The time offset of the start and / or end of the time domain resource can be indicated by physical layer signaling and / or MAC CE and / or RRC signaling, for example, can be a frame offset and / or a subframe offset and / or a slot offset and / or a symbol offset.

[0101] In one example, the new time unit is configured by the network side or is pre-agreed based on a standard. For example, the length of a data slice is taken as a time unit. For example, as shown in FIG. 5, the data 0 / 1 in the downlink direction (R2D) or the uplink direction (D2R) is pre-agreed by the standard to be one time unit.

[0102] In the above example, the number of new time units can be pre-agreed based on a standard or configured by the network side, and the specific configuration manner is not limited in the present application.

[0103] In the above examples, “downlink” is the link direction in which the network device and / or the first device sends signals to the first terminal device. “Downlink” can also be referred to as R2D / reader to device / reader to tag / reader to ambient IoT device, and the like.

[0104] In the above examples, “downlink” is the link direction in which the network device and / or the first device sends signals to the first terminal device. “Downlink” can also be referred to as R2D / reader to device / reader to tag / reader to ambient IoT device, and the like.

[0105] In the above examples, “uplink” is the link direction in which the second terminal device sends signals to the network device and / or the first device. “Uplink” can also be referred to as D2R / device to reader / tag to reader / ambient IoT device to reader, and the like.

[0106] In the above examples, “uplink” is the link direction in which the second terminal device sends signals to the network device and / or the first device. “Uplink” can also be referred to as D2R / device to reader / tag to reader / ambient IoT device to reader, and the like.

[0107] In the above embodiments, regarding the time duration of the time domain resource:

[0108] In some possible implementations, the time duration of the time domain resource is in units of frames and / or subframes and / or slots and / or symbols. For example, the time duration of the time domain resource is L frames or subframes or slots or symbols.

[0109] In one example, L is pre-agreed in a standard, for example, the value and unit of L are pre-agreed in a standard.

[0110] In another example, L is configured by the network side, for example, the value range of L is {0, 1, 2, …, 13}, and the specific value of L is configured by the network side; for another example, L is jointly indicated with the start of the time domain resource, for example, the number of continuous symbols L is determined by means of SLIV, that is, the corresponding index or value of SLIV is indicated, thereby the corresponding start symbol position and the number of continuous symbols can be determined.

[0111] In some other possible implementations, the time duration of the time domain resource is in units of absolute time T (for example, seconds, milliseconds, microseconds, and the like).

[0112] In one example, L is predefined in a standard, for example, the standard can predefine the value of T.

[0113] In another example, L is configured by the network side, for example, the value range of L is {T1, T2, T3, …}, and the network side indicates that T can take one value in the above value range.

[0114] In yet some possible implementation manners, the duration of the time domain resource is in a new time unit, for example, in a new time unit different from the frame, subframe, slot, symbol defined in the NR system. The time offset of the duration of the time domain resource can be indicated by physical layer signaling and / or MAC CE and / or RRC signaling, for example, can be a frame offset and / or a subframe offset and / or a slot offset and / or a symbol offset.

[0115] In one example, the new time unit is configured by the network side or is based on the standard pre-agreement. For example, the data slice length predefined in the standard is taken as the time unit. For example, as shown in FIG. 5, the standard pre-agrees that the data 0 / 1 in the downlink direction (R2D) or the uplink direction (D2R) is one time unit.

[0116] In the above example, the number of the new time unit can be pre-defined based on the standard or configured by the network side, and the application does not limit the specific configuration manner.

[0117] In the above example, the meanings of “downlink” and “uplink” are the same as the foregoing, which will not be repeated here.

[0118] In the above embodiment, regarding the period of the time domain resource:

[0119] In one example, the frame where the second reference time domain resource and / or the third reference time domain resource and / or the fourth reference time domain resource is located is frame SFN, the subframe is subframe X, the slot is slot n, and the time offset of the second time domain resource and / or the third time domain resource and / or the fourth time domain resource is Y.

[0120] In the above example, the first device can transmit the first third signal in frame SFN+Y or subframe X+Y or time slot n+Y; the first device can transmit the second third signal in frame SFN+Y+P or subframe X+Y+P or time slot n+Y+P, where P is a periodic value; and so on. That is, the time domain resource of the third signal is the Sth symbol in time slot n+Y+x*P, where x={0, 1, 2, …}.

[0121] In the above example, P can be a fixed value, for example, pre-defined in the protocol, and the application is not limited thereto. P can also be a value configured by the network side, for example, P is configured by the above-mentioned first signal or fifth signal.

[0122] In the above embodiment, the reference subcarrier spacing of the time domain resource is:

[0123] In some possible implementation manners, the reference subcarrier spacing of the time domain resource is pre-agreed by the standard, and / or is determined according to a predetermined rule, and / or is configured by a signal from the network device.

[0124] In one example, the standard pre-agrees the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal. For example, the standard pre-agrees that the subcarrier spacing of the first device for transmitting the third signal is 15 kHz or 30 kHz or 60 kHz, and so on. For another example, the standard pre-agrees that the subcarrier of the first device for receiving the fourth signal is 15 kHz. For another example, the standard pre-agrees that the subcarrier spacing of the first device for transmitting the third signal and receiving the fourth signal is the same, for example, both is 15 kHz.

[0125] In another example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal is determined according to a predetermined rule. For example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal (that is, the reference SCS of the third time domain resource and / or the fourth time domain resource) is the SCS of receiving the first signal or the fifth signal. For another example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal (that is, the reference SCS of the third time domain resource and / or the fourth time domain resource) is the SCS of PDCCH or PDSCH or PUCCH or PUSCH. For another example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal is the reference SCS of the active uplink / downlink BWP (active UL / DL BWP). For another example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal is the SCS of other uplink signal or channel and / or downlink signal or channel. For another example, the reference SCS of the first device for transmitting the third signal and / or receiving the fourth signal is the reference SCS of the UL-DL TDD configuration.

[0126] In yet another example, the first device is configured by the first signal or the fifth signal to transmit the third signal and / or receive the fourth signal with a reference SCS. The present application does not limit the specific configuration manner.

[0127] In some embodiments, as previously described, the time domain resource related to the third signal and / or the fourth signal is, for example, a third time domain resource for carrying the third signal and / or a fourth time domain resource for carrying the fourth signal, or a third reference time domain resource for determining the third time domain resource and / or a fourth reference time domain resource for determining the fourth time domain resource.

[0128] In the above embodiments, as to the third time domain resource and the third reference time domain resource, in some possible implementation manners, the third reference time domain resource is used to determine the start and / or end of the third time domain resource.

[0129] As to the start of the third time domain resource:

[0130] In some possible implementation manners, the third time domain resource starts at the symbol offset in the slot offset after the third reference time domain resource or the end of the third reference time domain resource or the start of the third reference time domain resource. The slot offset and / or the symbol offset can be included in the time domain resource information or can be pre-agreed by the standard, and is an integer greater than or equal to 0.

[0131] For example, the third time domain resource can start at the symbol offset in the slot offset after the end or start of the first slot or the last slot or the N1th slot where the start of the third reference time domain resource is located, as shown in (a) of FIG. 6. For another example, the third time domain resource can also start at the symbol offset in the slot offset in the N2th frame or subframe after the start or end of the frame or subframe where the end of the third reference time domain resource is located, as shown in (b) of FIG. 6. For another example, the slot where the third time domain resource is located is Ks, + K, where n is the slot where the third reference time domain resource is located, K is the slot offset, μ1 is the subcarrier spacing configuration of the third time domain resource, and μ2 is the subcarrier spacing configuration of the third reference time domain resource (or the start or end thereof), as shown in (c) of FIG. 6.

[0132] For another example, the first device transmits a PUCCH with HARQ-ACK information corresponding to a bearer activation command at slot n, and the third time-domain resource is applied starting at the first slot after slot n+3N, where N is numerology, which is the number of slots in one subframe of the SCS configuration of the PUCCH.

[0133] In some possible implementation, the third time-domain resource starts at the third reference time-domain resource or T time after the end of the third reference time-domain resource or the start of the third reference time-domain resource. The T time can be in absolute time units, such as seconds, milliseconds, microseconds, etc. In addition, the T time can be included in the time-domain resource information or be pre-agreed by the standard.

[0134] For example, the third reference time-domain resource (or the start or end thereof) can be in time units such as frames or subframes or slots or symbols, or in absolute time units such as seconds or milliseconds or microseconds, and the application is not limited thereto. In the above example, the T time can be in absolute time units such as seconds or milliseconds or microseconds, and the application is not limited thereto. For example, the third time-domain resource starts T time after the end / start of the first slot or the last slot or the N1th slot of the third reference time-domain resource (or the start or end thereof). For another example, the third time-domain resource starts T time after the start or end of the frame or subframe or slot or symbol of the third reference time-domain resource (or the start or end thereof).

[0135] In yet some possible implementation, the third time-domain resource starts X time units after the third reference time-domain resource or the end of the third reference time-domain resource or the start of the third reference time-domain resource. The time unit can be included in the time-domain resource information or be pre-agreed by the standard. In addition, the X can be included in the time-domain resource information or be pre-agreed by the standard, and be an integer greater than or equal to 0.

[0136] For example, the third time-domain resource can start X time units after the end or start of the first slot or the last slot or the N1th slot of the third reference time-domain resource (or the start or end thereof). For another example, the third time-domain resource can also start X time units in the N2th frame or subframe after the start or end of the frame or subframe of the third reference time-domain resource (or the start or end thereof).

[0137] For the end of the third time-domain resource.

[0138] In some possible implementation manners, the third time domain resource ends at the (symbol offset)th symbol in the (slot offset)th slot after the third reference time domain resource or the end of the third reference time domain resource or the start of the third reference time domain resource. The slot offset and / or the symbol offset can be included in the time domain resource information or can be pre-agreed in a standard, and is an integer greater than or equal to 0.

[0139] For example, the third time domain resource can end at the (symbol offset)th symbol in the (slot offset)th slot after the end or start of the first slot or the last slot or the N1th slot in which the third reference time domain resource is located. For another example, the third time domain resource can also end at the (symbol offset)th symbol in the (slot offset)th slot in the N2th frame or subframe after the start or end of the frame or subframe in which the third reference time domain resource is located. For another example, the slot in which the third time domain resource is located is Ks, + K, where n is the slot in which the third reference time domain resource is located, K is the slot offset, μ1 is a subcarrier spacing configuration of the third time domain resource, and μ2 is a subcarrier spacing configuration of the third reference time domain resource.

[0140] In some possible implementation manners, the third time domain resource ends T time after the third reference time domain resource or the end of the third reference time domain resource or the start of the third reference time domain resource. The T time can be in units of absolute time, for example, in units of seconds, milliseconds, microseconds, and the like. The T time can be included in the time domain resource information or can be pre-agreed in a standard.

[0141] For example, the third reference time domain resource (or the start or end thereof) can be in units of time units such as frames or subframes or slots or symbols, or in units of absolute time such as seconds or milliseconds or microseconds, and the like, without being limited thereto. In the above examples, the T time can be in units of absolute time such as seconds or milliseconds or microseconds, and the like, without being limited thereto. For example, the third time domain resource ends T time after the end / start of the first slot or the last slot or the N1th slot in which the third reference time domain resource is located. For another example, the third time domain resource ends T time after the start or end of the frame or subframe or slot or symbol in which the third reference time domain resource is located.

[0142] In yet some possible time slot manners, the third time domain resource ends at a third reference time domain resource or a third reference time domain resource end or a third reference time domain resource start plus an Xth time unit. The time unit can be included in the time domain resource information or be pre-agreed by the standard. In addition, the X can be included in the time domain resource information or be pre-agreed by the standard, and be an integer greater than or equal to 0.

[0143] For example, the third time domain resource can end at the end or start of a first time slot or a last time slot or an N1th time slot where the third reference time domain resource (or the start or end thereof) is located, plus an Xth time unit. For another example, the third time domain resource can also end at the start or end of an N2th frame or subframe, plus an Xth time unit, where the third reference time domain resource (or the start or end thereof) is located in the frame or subframe.

[0144] In some possible implementation manners, the third reference time domain resource is at least one of:

[0145] a first time domain resource for carrying the first signal;

[0146] a third time domain resource related to the first signal before the current third time domain resource;

[0147] a start of a period where the current third time domain resource is located;

[0148] a time domain resource for scheduling or indicating scheduling information or indication information (DCI / MAC CE) of the current third time domain resource.

[0149] In the above implementation manners, a time interval between the third time domain resource and the third reference time domain resource can be not greater than a first threshold (Tmax1) and / or not less than a second threshold (Tmin1).

[0150] The following is an example.

[0151] In some examples, the third reference time domain resource is a first time domain resource for carrying a first signal, the first signal is related to a third signal, and the third signal is located after the first signal in the time domain.

[0152] In the above examples, a time interval between the third time domain resource and the first time domain resource (or the third reference time domain resource) is not greater than Tmax1 and / or not less than Tmin1.

[0153] In one example, the first signal contains N pieces of time domain resource information related to the third signals, wherein the nth third time domain resource carries the nth third signal, n is an integer greater than 1 and less than or equal to N, and N is an integer greater than or equal to 1. The time interval between the end of the first time domain resource and the start of the nth third time domain resource is not greater than the first threshold (Tmax1) and / or not less than the second threshold (Tmin1).

[0154] In other examples, the third reference time domain resource is a third time domain resource related to the first signal before the current third time domain resource.

[0155] In one example, the first signal contains N pieces of time domain resource information related to the third signals, wherein the nth third time domain resource carries the nth third signal, n is an integer greater than 0 and less than or equal to N, and N is an integer greater than or equal to 1. The third reference time domain resource is the nth’ third time domain resource, for example, the third reference time domain resource of the nth+1 third time domain resource is the nth’ third time domain resource, wherein n’ is an integer greater than or equal to 1 and less than or equal to n, as shown in FIG. 7. The time interval between the end of the nth’ third time domain resource and the start of the nth third time domain resource is not greater than the first threshold (Tmax1) and / or not less than the second threshold (Tmin1).

[0156] In the above example, the nth third signal can be a signal carrying R2D data information, can be an R2D synchronization signal, can be a signal carrying an R2D command, etc., which is not limited in the present application.

[0157] In yet other examples, the third reference time domain resource is the start of a period.

[0158] For example, the time domain resource information related to the third time domain resource contains a period. The third time domain resource starts and / or ends at a time offset after the start of the period.

[0159] In yet other examples, the third reference time domain resource is a time domain resource of scheduling information (DCI, MAC CE, etc.) of the third time domain resource.

[0160] For example, the first signal is carried by a PDSCH, and the first signal is time domain resource configuration information (RRC configuration information). The scheduling information (MAC CE or DCI) of the third time domain resource activates the configured third time domain resource.

[0161] In the implementation manners above, the second threshold (Tmin1) can be related to the capability of the first device, and can be pre-agreed in a standard or configured by the network side. For example, the first device reports capability information, and the network side configures the second threshold (Tmin1) according to the capability information reported by the first device. The specific configuration manner is not limited in the application. The related content about the capability information reported by the first device has been described above, and will not be repeated here.

[0162] In the implementation manners above, the first threshold (Tmax1) can be pre-agreed in a standard or configured by the network side. Similar to the second threshold (Tmin1), the specific configuration manner of the first threshold (Tmax1) is not limited in the application.

[0163] In the implementation manners above, if the action of receiving the first signal and sending the third signal by the first device is continuous, that is, the first device sends the third signal after receiving the first signal, Tmin1 and Tmax1 limit the time interval between the first time domain resource (or the start or end thereof) carrying the first signal and the third time domain resource (or the start or end thereof) carrying the third signal. For example, the first device starts to send a plurality of third signals configured or indicated in relation to the first signal after receiving the first signal, and Tmin1 and Tmax1 limit the time interval between the first signal and the first third signal.

[0164] According to the above embodiments, by limiting Tmin1, it is ensured that the first device can complete the processing of receiving the first signal and the processing before sending the third signal, so as to avoid the conflict between receiving and sending. In addition, by limiting Tmax1, the time delay of the first device sending the third signal is limited.

[0165] The third time domain resource and the third reference time domain resource are exemplarily described above. As for the fourth time domain resource and the fourth reference time domain resource, in some possible implementation manners, the fourth reference time domain resource is used to determine the start and / or end of the fourth time domain resource, and the determination method is similar to that of the start and / or end of the third time domain resource, which will not be repeated here.

[0166] In some possible implementation manners, the fourth reference time domain resource is at least one of the following:

[0167] The time domain resource of the preamble and / or midamble and / or postamble of the third signal;

[0168] The third time domain resource;

[0169] The fourth time domain resource related to the first signal before the current fourth time domain resource;

[0170] The first time domain resource for carrying the first signal;

[0171] a period in which the fourth time-domain resource is located starts;

[0172] a time-domain resource for scheduling or indicating scheduling information or indication information (DCI / MAC CE) of the current fourth time-domain resource.

[0173] In the implementation manner described above, a time interval between the fourth time-domain resource and the fourth reference time-domain resource can be not greater than the third threshold (Tmax2) and / or not less than the fourth threshold (Tmin2).

[0174] In the implementation manner described above, the third signal is related to the fourth signal, and the fourth signal is located after the third signal in the time domain; and / or, the first signal is related to the fourth signal, and the fourth signal is located after the first signal in the time domain.

[0175] The following is an example.

[0176] In some examples, the fourth reference time-domain resource is the third time-domain resource.

[0177] For example, the first signal contains N pieces of time-domain resource information related to the third signal, where the nth third time-domain resource carries the nth third signal, n is an integer greater than 0 and less than or equal to N, and N is an integer greater than or equal to 1. The time between the end of the nth third time-domain resource and the start of the fourth time-domain resource is not greater than the third threshold (Tmax2) and / or not less than the fourth threshold (Tmin2).

[0178] For another example, the first signal contains N pieces of time-domain resource information related to the fourth signal, where the nth fourth time-domain resource carries the nth fourth signal, n is an integer greater than 0 and less than or equal to N, and N is an integer greater than or equal to 1. The time between the end of the third time-domain resource and the start of the nth fourth time-domain resource is not greater than the third threshold (Tmax2) and / or not less than the fourth threshold (Tmin2), and the nth fourth signal is used for responding to the third signal.

[0179] In the above examples, the third signal carried by the third time-domain resource can be a signal carrying R2D data information, can be an R2D synchronization signal, can be a signal carrying an R2D command, and the like, which are not limited in the present application.

[0180] In some other examples, the fourth reference time-domain resource is a time-domain resource of a preamble and / or a midamble and / or a postamble of the third signal.

[0181] For example, the third signal contains a preamble and / or a midamble and / or a postamble, as shown in FIG. 8, the fourth time-domain resource starts and / or ends after a time offset after the time-domain resource of the preamble and / or the midamble and / or the postamble of the third signal.

[0182] In yet some examples, the fourth reference time domain resource is a fourth time domain resource related to the first signal before the current fourth time domain resource.

[0183] For example, the first signal contains N pieces of fourth signal related time domain resource information, where the nth fourth time domain resource carries the nth fourth signal, n is an integer greater than 0 and less than or equal to N, and N is an integer greater than or equal to 1. The fourth reference time domain resource of the (n+1)th fourth time domain resource is the nth’ fourth time domain resource, where n’ is an integer greater than or equal to 1 and less than or equal to n, as shown in FIG. 9.

[0184] In the above example, the time between the end of the nth’ fourth time domain resource and the start of the nth fourth time domain resource is not greater than a third threshold (Tmax2) and / or not less than a fourth threshold (Tmin2).

[0185] In yet some examples, the fourth reference time domain resource is a first time domain resource for carrying the first signal.

[0186] For example, the first signal contains N pieces of fourth signal related time domain resource information, where the nth fourth time domain resource carries the nth fourth signal, n is an integer greater than 0 and less than or equal to N, and N is an integer greater than or equal to 1. The time between the end of the first time domain resource and the start of the nth fourth time domain resource is not greater than a third threshold (Tmax2) and / or not less than a fourth threshold (Tmin2).

[0187] In yet some examples, the fourth reference time domain resource is a time domain resource of scheduling information (DCI, MAC CE, etc.) of the fourth time domain resource.

[0188] For example, the first signal is carried by a PDSCH, and the first signal is time domain resource configuration information (RRC configuration information). The scheduling information (MAC CE or DCI) of the third time domain resource activates the configured third time domain resource.

[0189] In the above implementation, the fourth threshold (Tmin2) is determined at least according to the capability reported by the device (the second terminal device), for example, the Tmin2 is related to the device capability related to the device battery charging time and / or the device capability related to the signal processing time. By defining Tmin2, it can be ensured that the power of the device is sufficient to send the fourth signal to avoid the device from powering off during the sending of the fourth signal, resulting in the failure to complete the sending of the fourth signal, and the device ensures that the third signal is processed before the sending of the fourth signal to avoid the conflict. The example takes the case that the first terminal device and the second terminal device are the same, but the present application is not limited thereto. In addition, the above fourth threshold (Tmin2) can be a configured parameter or a protocol specified parameter.

[0190] In the above implementation, the third threshold (Tmax2) is determined at least according to the capability reported by the device (the second terminal device), for example, the Tmax2 is related to the device crystal oscillator accuracy. By defining Tmax2, it can be ensured that the time domain resource for the device to send the fourth signal is within the time range in which the device can ensure synchronization accuracy. The example takes the case that the first terminal device and the second terminal device are the same, but the present application is not limited thereto. In addition, the above third threshold (Tmax2) can be a configured parameter or a protocol specified parameter.

[0191] In the above implementation, if the actions of the first device to send the third signal and to receive the fourth signal are continuous, that is, the first device receives the fourth signal after the sending of the third signal is completed, then Tmin2 and Tmax2 limit the time interval between the third time domain resource (or the start or end thereof) carrying the third signal and the fourth time domain resource (or the start or end thereof) carrying the fourth signal. For example, the first device starts to receive one or more fourth signals after sending a plurality of third signals, then Tmin1 and Tmax1 limit the time interval between the last sent third signal and the first fourth signal.

[0192] In some embodiments, as described above, the first device also receives a fifth signal from the network device, and the fifth signal is at least used to indicate the first time domain resource for carrying the first signal and / or the second time domain resource for carrying the second signal.

[0193] In the above embodiments, the first signal can be a PDSCH or a PDCCH, for example, the first signal carries time domain resource configuration information, the first signal is carried by a PDSCH, that is, the time domain resource configuration information is configured by high layer signaling; for another example, the first signal carries time domain resource scheduling information, the first signal is carried by a PDCCH, that is, the time domain resource scheduling information is configured by physical layer signaling.

[0194] In the above embodiments, the second signal can be a PUSCH or a PUCCH.

[0195] In the above embodiments, the fifth signal can be a PDSCH or a PDCCH.

[0196] In the above embodiments, the time domain resource carrying the fifth signal can be used to determine the start and / or end of the first time domain resource and / or the second time domain resource. The specific determination method is similar to the determination method of the start and / or end of the third time domain resource and / or the fourth time domain resource, which will not be described here.

[0197] In some embodiments, the first signal further includes time domain resource information related to the second signal.

[0198] In the above embodiments, as described above, the time domain resource related to the second signal can be a second time domain resource for carrying the second signal, or a second reference time domain resource for determining the second time domain resource, for example, a second reference time domain resource for determining the start and / or end of the second time domain resource.

[0199] In the above embodiments, the second reference time domain resource is, for example, at least one of the following:

[0200] The fourth time domain resource for carrying the fourth signal;

[0201] The time domain resource of the preamble and / or midamble and / or postamble of the fourth signal;

[0202] The first time domain resource for carrying the first signal;

[0203] The start of the period in which the second time domain resource is located;

[0204] The time domain resource of the scheduling information or indication information (DCI / MAC CE) for scheduling or indicating the second time domain resource.

[0205] In some possible implementation manners, the time interval between the second time domain resource and the second reference time domain resource is not greater than a fifth threshold (Tmax3) and / or not less than a sixth threshold (Tmin3).

[0206] In some possible implementation manners, the second signal is related to the fourth signal, and the second signal is located after the fourth signal in the time domain.

[0207] The following is an example.

[0208] In some examples, the second reference time domain resource is a fourth time domain resource.

[0209] For example, the first signal contains time domain resource information of a fourth signal. The second time domain resource starts and / or ends at a time offset after the fourth time domain resource and / or the start of the fourth time domain resource and / or the end of the fourth time domain resource, as shown in FIG. 10.

[0210] For another example, the first signal contains N pieces of time domain resource information of a fourth signal, where N is an integer greater than 1. The second time domain resource starts and / or ends at a time offset after the nth fourth time domain resource and / or the start of the nth fourth time domain resource and / or the end of the nth fourth time domain resource, where n is greater than or equal to 1 and less than or equal to N, as shown in FIG. 11.

[0211] In other examples, the second reference time domain resource is a time domain resource of a preamble and / or a midamble and / or a postamble of the fourth signal.

[0212] For example, the fourth signal contains a preamble and / or a midamble and / or a postamble, as shown in FIG. 12, the second time domain resource starts and / or ends at a time offset after the time domain resource of the preamble and / or the midamble and / or the postamble of the fourth signal.

[0213] In yet other examples, the second reference time domain resource is the first time domain resource. This example is similar to the third reference time domain resource and the fourth reference time domain resource, which will not be described here.

[0214] In yet other examples, the second reference time domain resource is a time domain resource of scheduling information of the second time domain resource.

[0215] For example, the first signal is carried by a PDSCH, and the first signal further includes time domain resource configuration information (RRC configuration information) of the second signal. The scheduling information (MAC CE or DCI) of the second time domain resource activates the configured second time domain resource.

[0216] In the above implementation, the sixth threshold (Tmin3) is related to the capability reported by the first device, and the sixth threshold (Tmin3) can be specified by a protocol or configured by a network side, and the specific configuration manner is not limited by the present application.

[0217] In the above implementation, the fifth threshold (Tmax3) can be specified by a protocol or configured by a network side, and the specific configuration manner is not limited by the present application. In the above implementation, the fifth threshold (Tmax3) can be specified by a protocol or configured by a network side, and the specific configuration manner is not limited by the present application.

[0218] According to the above embodiment, by limiting the sixth threshold value (Tmin3), it is ensured that the first device can complete the processing of receiving the fourth signal and the processing before sending the second signal, avoiding the conflict between receiving and sending. In addition, by limiting the fifth threshold value (Tmax3), the time delay of the first device sending the second signal is limited.

[0219] In the above embodiment, if the actions of the first device sending the second signal and receiving the fourth signal are continuous, that is, the first device sends the second signal after receiving the fourth signal ends, Tmin3 and Tmax3 limit the time interval between the fourth time domain resource (or the start or end thereof) carrying the fourth signal and the second time domain resource (or the start or end thereof) carrying the second signal. For example, the first device starts to send one or more second signals after receiving one or more fourth signals, and Tmin3 and Tmax3 limit the time interval between receiving the last fourth signal and sending the first second signal.

[0220] In some embodiments, the fourth signal is also used in response to the third signal. That is, the second terminal device sends the fourth signal after the first terminal device receives the third signal.

[0221] In the above embodiment, one fourth signal can be used to respond to one third signal. The application is not limited thereto, and more than one fourth signal can also be used to respond to one third signal. For example, the second terminal device sends multiple fourth signals within a certain time.

[0222] According to the above embodiment, since the terminal device (the first terminal device / the second terminal device) has weak capability and cannot spontaneously send an uplink signal, but can send a signal (the fourth signal) in response to the third signal, the downlink command / inventory can be responded to.

[0223] The above embodiments only exemplarily illustrate the embodiments of the application, but the application is not limited thereto, and appropriate modifications can be made on the basis of the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0224] According to the embodiments of the application, the problem of which time domain resources the first device (intermedia UE) uses to send the third signal and / or receive the fourth signal in the topology of the ambient IoT system with the first device (intermedia UE) is solved, and the reliability of signal transmission and reception is improved.
