Description

[0001] This application is a divisional application. The application number of the original application is 201980094493.0, and the original application date is March 29, 2019. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] For some services, the interval between two services is long and the communication data packets are small. In order to achieve energy saving and reduce signaling overhead, LTE release-16 decided to standardize the mechanism of transmission on pre-defined resources, that is, communication that does not require dynamic downlink control information (DCI) scheduling, so it is also called scheduling-free transmission. The process of uplink scheduling-free transmission is: when the terminal device has uplink data to send, the network device does not need to dynamically schedule the uplink for the terminal device, and the terminal device performs uplink transmission on the pre-configured transmission resources according to the pre-defined transmission method.

[0004] At present, after the terminal device performs uplink transmission on the preconfigured uplink resource transmission (PUR), the network device can feedback ACK / NACK information in the PDCCH, where ACK indicates that the preconfigured resource transmission is successful and NACK indicates that the preconfigured resource transmission fails. After the network device feedbacks the ACK / NACK information, the terminal device needs to continue to monitor whether there is DCI for scheduling downlink data within a certain period of time, and receive downlink data through the DCI. It can be seen that the terminal device needs to blindly detect the DCI for scheduling downlink data during the downlink scheduling process, which increases the power consumption of the terminal device. Summary of the invention

[0005] The embodiments of the present application provide a communication method and device for solving the problem of power consumption waste of terminal devices during downlink scheduling in the prior art.

[0006] In the first aspect, an embodiment of the present application provides a communication method, including: a first device determines first control information, the first control information includes first indication information and second indication information, wherein the first indication information is used to indicate the state of pre-configured resource transmission, the state including successful transmission or unsuccessful transmission or scheduled retransmission or retransmission in pre-configured resources; the second indication information is used to indicate whether the first device transmits the first information, the first information includes high-layer data and / or reconfiguration information of pre-configured uplink resources; the first device sends the first control information to the second device. In the embodiment of the present application, when the first device feeds back the state of pre-configured resource transmission to the second device, it indicates whether the second device transmits high-layer data and / or PUR reconfiguration information, so that the second device can determine whether to receive high-layer data and / or PUR reconfiguration information when receiving the state of pre-configured resource transmission. Compared with the method of blindly detecting the DCI of the second device scheduling downlink data in the prior art, in the embodiment of the present application, the first device can notify the second device through the first control information when it does not transmit high-layer data and / or PUR reconfiguration information, so that the second device does not need to monitor the DCI of scheduling high-layer data, so that the second device can reduce the number of blind detections, thereby saving the power consumption of the second device.

[0007] In one possible design, the first control information is downlink control information.

[0008] In one possible design, the second indication information may include: indication information for indicating whether the first information is carried in a physical shared channel scheduled by the first control information; or, the second indication information includes: indication information for indicating whether the terminal device detects second control information, and the second control information is used to schedule the first information; or, the second indication information includes: indication information for indicating whether the first control information includes pre-configured uplink resource reconfiguration information; or, the second indication information includes: indication information for indicating whether the terminal device includes pre-configured uplink resource reconfiguration information in the first control information, and indication information for indicating whether the terminal device detects third control information, and the third control information is used to schedule the high-layer data.

[0009] In one possible design, the first field of the first control information can be used to indicate the second indication information. In the above design, by reusing a field in the first control information to indicate the second indication information, it is possible to avoid increasing the control information overhead, thereby avoiding reducing the spectrum efficiency, and improving the utilization of system resources and avoiding increasing the user power consumption.

[0010] In one possible design, the first control information is control information of format 6-1A or format 6-1B, and the first field may be a resource block allocation field of the first control information.

In the above design, there are some redundant states in the starting number field of physical random access channel repetitions, or the subcarrier indication field of a physical random access channel in the control information of format N1 used to indicate the physical control channel instruction, and the control information also includes some unused reserved fields. By using redundant states or reserved fields to indicate the second indication information, it is possible to avoid adding bits to the first control information, thereby effectively avoiding increasing control information overhead, and improving system resource utilization, and improving the flexibility of DCI use.

[0015] In one possible design, the second field and the third field of the first control information are used to indicate the second indication information. In the above design, by multiplexing two fields in the first control information to indicate the second indication information, not only can the increase of control information overhead be avoided and the utilization rate of system resources be improved, but also the accuracy of indicating the second indication information can be improved.

[0016] In one possible design, the second field may be the resource block allocation field of the first control information; if all bits in the second field are set to 1, the third field is used to indicate the second indication information.

After the second device determines that the second indication information indicates that the first device transmits the first information, it receives the first information according to the second indication information. In the embodiment of the present application, when the first device feeds back the status of pre-configured resource transmission to the second device, it indicates whether the second device transmits high-layer data and / or PUR reconfiguration information, so that the second device can determine whether to receive high-layer data and / or PUR reconfiguration information when receiving the status of pre-configured resource transmission. Compared with the method in the prior art in which the second device blindly checks the DCI for scheduling downlink data, in the embodiment of the present application, the first device can notify the second device through the first control information when no high-level data and / or PUR reconfiguration information is transmitted, so that the second device does not need to monitor the DCI for scheduling high-level data, so that the second device can reduce the number of blind checks, thereby saving the power consumption of the second device.

[0046] The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0047] The communication method provided in the present application can be applied to various communication systems, for example, the Internet of Things (IoT), narrowband Internet of Things (NB-IoT), long term evolution (LTE), fifth generation (5G) communication system, LTE and 5G hybrid architecture, 5G new radio (NR) system, global system for mobile communication (GSM), universal mobile telecommunications system (UMTS), code division multiple access (CDMA) system, and new communication systems that will emerge in the future development of communication. As long as there is an entity in the communication system that can send control information for scheduling transmission blocks, and send and receive transmission blocks, and another entity can receive control information for scheduling transmission blocks, and receive and send transmission blocks, the communication method provided in the embodiments of the present application can be used.

[0048] The terminal device involved in the embodiments of the present application is a device that provides voice and / or data connectivity to users, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device may also be other processing devices connected to a wireless modem. The terminal device may communicate with one or more core networks through a radio access network (RAN). The terminal device may also be referred to as a wireless terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment, etc. The terminal device may be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a wireless access network. For example, the terminal device may also be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. Common terminal devices include, for example, mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, etc., but the embodiments of the present application are not limited thereto.

[0049] The network device involved in the embodiments of the present application can be used to convert received air frames to Internet Protocol (IP) packets and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network, etc. The network device can also coordinate the attribute management of the air interface. For example, the network device may be a base transceiver station (BTS) in a global system for mobile communication (GSM) or code division multiple access (CDMA), a base station (NodeB) in wideband code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in LTE, a new radio controller (NR controller), a gNode B (gNB) in a 5G system, a centralized unit, a new wireless base station, a radio frequency remote module, a micro base station, a relay, a distributed unit, a transmission reception point (TRP) or a transmission point (TP) or any other wireless access device, but the embodiments of the present application are not limited thereto. The network device may cover one or more cells.

[0050] See also Figure 1 As shown, a communication system provided by an embodiment of the present application includes a network device and six terminal devices, namely UE1 to UE6. In the communication system, UE1 to UE6 can send uplink data to the network device, and the network device can receive uplink data sent by UE1 to UE6. In addition, UE4 to UE6 can also form a sub-communication system. The network device can send downlink information to UE1, UE2, UE3, and UE5, and UE5 can send downlink information to UE4 and UE6 based on device-to-device (D2D) technology. Figure 1 It is only a schematic diagram and does not specifically limit the type of communication system, or the number and type of devices included in the communication system.

[0051] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0052] In a communication system, a UE may be in three states: idle, inactive, and connected. A connected UE can communicate with a base station and transmit data through dynamic scheduling of the base station, while an idle UE cannot transmit data through dynamic scheduling of the base station. It needs to perform random access first and establish an RRC connection before it can transmit data, or carry a small amount of uplink data in message 3 during the random access process. The inactive state can be regarded as an intermediate state between these two states. The UE and the core network retain the context of the radio resource control (RRC) message in the connected state, so it can enter the connected state faster than the idle state. According to the current LTE protocol, when the UE changes from the RRC connected state to the idle state, the RRC configuration message is not retained, but when the connected state changes to the inactive state, the context of the RRC message is retained.

[0053] For some services, in order to reduce resource consumption, reduce data transmission delay and save energy, such as Figure 2 As shown, services can be transmitted on predefined resources, that is, there is no need for dynamic downlink control information (DCI) scheduling, and users transmit signals on preconfigured resources. This type of transmission is called configured scheduled transmission, also called preconfigured resource transmission or preconfigured resource scheduling-free transmission or scheduling-free transmission. In particular, the preconfigured resources can be preconfigured uplink resources. The process of uplink scheduling-free transmission or preconfigured uplink resource transmission (PUR) is as follows: when a terminal device has uplink data to send, the network device does not need to perform dynamic uplink scheduling on the terminal device, and the terminal device performs uplink transmission on the preconfigured transmission resources in accordance with a predetermined transmission method.

[0054] At present, after the terminal device performs uplink transmission on the preconfigured uplink resource transmission (PUR), the network device can feedback ACK / NACK information in the PDCCH, where ACK indicates that the preconfigured resource transmission is successful and NACK indicates that the preconfigured resource transmission fails. After the network device feedbacks the ACK / NACK information, the terminal device needs to continue to monitor whether there is DCI for scheduling downlink data within a certain period of time, and receive downlink data through the DCI. It can be seen that the terminal device needs to blindly detect the DCI for scheduling downlink data during the downlink scheduling process, which increases the power consumption of the terminal device.

[0055] Based on this, the embodiment of the present application provides a communication method and device for solving the problem of power consumption waste of terminal devices in the downlink scheduling process in the prior art. The method and the device are based on the same inventive concept. Since the principles of solving the problem by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0056] The multiple involved in the embodiments of the present application refers to two or more.

[0057] It should be understood that, in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0058] See also Figure 3 , is a flow chart of a communication method provided by the present application. The method can be applied to Figure 1 A second device in the communication system, the method comprising:

[0059] S301, a first device determines first control information, the first control information includes first indication information and second indication information, wherein the first indication information is used to indicate a status of pre-configured resource transmission, the status including successful transmission or unsuccessful transmission or scheduled retransmission or retransmission in pre-configured resources; the second indication information is used to indicate whether the first device transmits first information, the first information includes high-layer data and / or PUR reconfiguration information.

[0060] Among them, "high-layer data" can also be called "downlink data", or "data", or can also be called "downlink high-layer data". It can be understood that after the second device successfully transmits information to the first device through the preconfigured transmission method, the first device and the second device will have corresponding interactive information, such as high-layer ACK.

[0061] In a specific implementation, the first control information includes the first indication information, in which case the first control information may not include the second indication information. Alternatively, the first control information includes the second indication information, in which case the first control information may not include the first indication information. Alternatively, the first control information may also include high-layer data and / or PUR reconfiguration information when the first indication information indicates successful transmission (i.e., ACK), and include PUR reconfiguration information when the first indication information indicates unsuccessful transmission or scheduled retransmission or retransmission in preconfigured uplink resources (i.e., NACK).

[0062] It should be noted that the preconfigured uplink resource (PUR) is only an exemplary name. Its essence is that the network device configures the resource, and the second device can transmit uplink information on the resource without the need for dynamic scheduling or downlink control information scheduling of the first device. The resource can also be named by other names, such as configuration authorization resource. It should be understood that if the configuration authorization resource can also realize the function realized by the preconfigured uplink resource in the embodiment of the present application, the configuration authorization resource can also be understood as the preconfigured uplink resource in the embodiment of the present application. For the convenience of description, the resource is uniformly referred to as preconfigured uplink resource in the embodiment of the present application.

[0063] Preconfigured resource transmission may refer to the second device transmitting data in accordance with pre-defined parameters on preconfigured uplink resources. In the embodiments of the present application, "preconfigured resource transmission" may also be referred to as "preconfigured transmission mode", "scheduling-free transmission", "preconfigured resource transmission", "preconfigured resource scheduling-free transmission", etc. It should be understood that "preconfigured resource transmission" in the embodiments of the present application is only an exemplary description. In actual applications, "preconfigured resource transmission" may also be named as other names. If the other names can also realize the function of "preconfigured resource transmission" in the implementation of the present application, they can be understood as uplink signal transmission in accordance with the preconfigured resource transmission mode. For the convenience of description, the transmission mode is uniformly referred to as preconfigured resource transmission in the embodiments of the present application.

[0064] Preconfigured resource retransmission may refer to retransmission in preconfigured uplink resources or in part of preconfigured uplink resources, that is, no dynamic scheduling information (such as DCI) scheduling is required, but retransmission is performed through preconfigured uplink resources, but the configuration information of the corresponding preconfigured resources can be reconfigured or updated through dynamic scheduling information.

[0065] Scheduling retransmission means that the second device retransmits according to scheduling information of dynamic scheduling information (such as DCI) of the first device.

[0066] Among them, the reconfiguration information of the pre-configured uplink resources may include but is not limited to one or more of the following information: time (timing) advance, power control information, number of repetitions, modulation and coding scheme (MCS), transport block size (TBS), etc.

[0067] Exemplarily, the first control information may be downlink control information in an LTE eMTC system, downlink control information in an NR system, etc., which is not specifically limited here. For the convenience of description, the following takes the first control information as downlink control information (DCI) as an example.

[0068] In a specific implementation, the second indication information may include: indication information for indicating whether the first information is carried in a physical downlink shared channel (PDSCH) scheduled by the first control information.

[0069] It should be noted that, in the embodiments of the present application, “the first control information schedules the first information”, “the first control information schedules PDSCH”, “the first information is carried in the PDSCH scheduled by the first control information”, and “there is first information” can all be understood as the PDSCH scheduled by the first control information including the first information.

[0070] Alternatively, the second indication information may also include: indication information used to indicate whether the second device detects second control information, and the second control information is used to schedule the first information.

[0071] It should be noted that, in the embodiments of the present application, "the second device detects the second control information" and "the second device monitors the first search space, and the first search space is the search space for carrying or transmitting the second control information" can be understood as the second device needs to monitor the second control information.

[0072] Alternatively, the second indication information may also include: indication information used to indicate whether the first control information includes pre-configured uplink resource reconfiguration information.

[0073] Alternatively, the second indication information may also include: indication information for indicating whether the second device includes pre-configured uplink resource reconfiguration information in the first control information, and indication information for indicating whether the second device detects third control information, and the third control information is used to schedule the high-layer data.

[0074] It should be noted that, in the embodiments of the present application, "the second device detects the third control information" and "the second device monitors the second search space, and the second search space is the search space for carrying or transmitting the third control information" can be understood as the second device needs to monitor the third control information.

[0075] The first device may be a network device, and the second device may be a terminal device. Alternatively, the second device may be a network device, and the first device may be a terminal device. Alternatively, the first device may be a device with a sending capability, and the second device may be a device with a receiving capability.

[0076] S302: The first device sends the first control information to the second device. Correspondingly, the second device determines whether to receive the first information based on the second indication information.

[0077] In a specific implementation, the first control information may be one or more control information. If the first control information is one control information, the control information includes two indication information, namely, the first indication information and the second indication information. If the first control information is multiple control information, one of the control information includes the first indication information, and the other control information includes the second indication information. The multiple control information may be sent together, so that the second device may receive the multiple control information together without performing additional detection.

[0078] S303: After determining that the second indication information instructs the first device to transmit the first information, the second device receives the first information according to the second indication information.

[0079] In an embodiment of the present application, when the first device feeds back the status of the pre-configured resource transmission to the second device, it indicates whether the second device transmits high-level data and / or pre-configured uplink resource reconfiguration information, so that the second device can determine whether to receive high-level data and / or pre-configured uplink resource reconfiguration information when receiving the status of the pre-configured resource transmission. Compared with the method of the second device blindly checking the DCI for scheduling downlink data in the prior art, in an embodiment of the present application, the first device can notify the second device through the first control information when it does not transmit high-level data and / or pre-configured uplink resource reconfiguration information, so that the second device does not need to monitor the DCI for scheduling high-level data, so that the second device can reduce the number of blind checks, thereby saving the power consumption of the second device.

[0080] For the convenience of description, in the embodiments of the present application, “the first information is carried in the PDSCH scheduled by the first control information”, “the first control information schedules PDSCH”, “the first control information indicates detection of the second control information”, and “the first control information indicates monitoring of the first search space” are collectively referred to as “scheduling the first information”. “The first control information schedules the PDSCH carrying high-layer data”, “the first control information indicates detection of the third control information”, “the first control information indicates monitoring of the second search space”, and “the first control information transmits high-layer data” are collectively referred to as “having high-layer data”. “The first control information schedules the PDSCH carrying PUR reconfiguration information”, and “the first control information includes PUR reconfiguration information” are collectively referred to as “including PUR reconfiguration information”.

[0081] In a specific implementation, the first device may indicate the second indication information in the first control information in the following two ways, but is not limited to:

[0082] In method 1, the first control information may indicate the second indication information through a field, such as the first field is used to indicate the second indication information. Further, when the first field indicates the second indication information, it can be considered that the pre-configured resource transmission is successfully transmitted, that is, the first field can indicate the successful transmission of the pre-configured resource transmission and the second indication information.

[0083] In an exemplary description, the first control information may be control information of format 6-1A or format 6-1B, and the first field may be a resource block assignment field of the first control information. For example, when all the bits in the first field take a value of 1, the second indication information may indicate that the first device does not schedule PDSCH, and may also indicate successful transmission. If not all the bits in the first field take a value of 1, the second indication information may indicate that the first device schedules PDSCH, and may also indicate successful transmission (or successful reception). Take the example where the first information includes high-layer data, as shown in Table 1. In the embodiment of the present application, "successful transmission" may also be referred to as "successful reception".

[0084] Table 1

[0085] resource block assignment Instructions All bits set to 1 Successfully received and no PDSCH is scheduled Other values ​​(not all 1) Successfully received and scheduled PDSCH

[0086] It should be noted that Table 1 is only an exemplary description, and the state, indication content, and correspondence between the state and indication content of the first field are not specifically limited. Alternatively, when all the bits in the first field are set to 1, the second indication information may indicate that the first device schedules the PDSCH, and may also indicate successful transmission. If not all the bits in the first field are set to 1, the second indication information may indicate that the first device does not schedule the PDSCH, and may also indicate successful transmission.

[0087] In another exemplary description, the first control information is control information of format N0, and the first field may be a subcarrier indication field or a modulation and coding scheme (MCS) field of the first control information. The redundant status of the subcarrier indication field and the MCS field may be shown in Table 2. For example, when the subcarrier spacing is 3.75kHz, a value of the Subcarrier indication field of 48-63 indicates successful reception and no PDSCH is scheduled. For another example: when the subcarrier spacing is 15kHz, a value of the Subcarrier indication field of 19-63 indicates successful reception and no PDSCH is scheduled. For another example: for single tone, a value of the MCS field of 11-15 indicates successful reception and no PDSCH is scheduled. For another example: for multi-tone, a value of the MCS field of 14 or 15 indicates successful reception and no PDSCH is scheduled.

[0088] Table 2

[0089]

[0090] In another exemplary description, the first control information is control information of formatN1, and the first control information is used to indicate scheduling authorization, and the first field may be an MCS field of the first control information. The redundant state of the MCS field can be shown in Table 3. For example, a value of 14 or 15 of the MCS field indicates successful reception and no PDSCH is scheduled.

[0091] Table 3

[0092]

[0093] In another exemplary description, the first control information is control information of formatN1, and the first control information is used to indicate a physical control channel instruction, and the first field may be a starting number field of physical random access channel repetitions of the first control information, or a subcarrier indication field of a physical random access channel, or a reserved field. The redundant state of the MCS field can be shown in Table 4. For example, when the value of the Subcarrier indication of NPRACH field is a value between 48 and 63, it indicates successful reception and no PDSCH is scheduled.

[0094] Table 4

[0095]

[0096] In mode 2, the first control information may indicate the second indication information through two fields, such as the second field and the third field are used to indicate the second indication information. When the first control information indicates the second indication information through the second field and the third field, it can be considered that the PUR is successfully transmitted, that is, the second field and the third field indicate that the preconfigured resource transmission is successfully transmitted and the second indication information.

[0097] In an exemplary description, the second field may be a resource block assignment field of the first control information. If all bits in the second field are set to 1, the third field may be used to indicate the second indication information.

[0098] The third field may indicate whether the first information is transmitted through two value states. For example, one state of the third field indicates that PDSCH is scheduled and may also indicate successful transmission, and another state of the third field indicates that PDSCH is not scheduled and may also indicate successful transmission, as shown in Table 5-1.

[0099] Table 5-1

[0100] The third field Instructions A state Successful transmission, no PDSCH scheduled Another state Successful transmission, PDSCH is scheduled

[0101] Taking the third field as the repetition number field as an example, and the first information including high-layer data as an example, when all bits in the repetition number field are set to 1, it can indicate successful transmission and no PDSCH is scheduled, as shown in Table 5-2.

[0102] Table 5-2

[0103] repetition number field Instructions All bits are set to 1 Successfully transmitted and no PDSCH is scheduled

[0104] It should be understood that Table 5-2 is merely an exemplary description and does not specifically limit the type of the third field, the state of the third field, the content indicated by the third field, the correspondence between the state and the indicated content, etc.

[0105] For another example, one state of the third field indicates that the first control information includes pre-configured uplink resource reconfiguration information, and may also indicate successful transmission, and another state of the third field indicates that the first control information does not include pre-configured uplink resource reconfiguration information, and may also indicate successful transmission. As shown in Table 5-3.

[0106] Table 5-3

[0107] The third field Instructions A state Successful transmission, including pre-configured uplink resource reconfiguration information Another state Successfully transmitted, without including pre-configured uplink resource reconfiguration information

[0108] The “including pre-configured uplink resource reconfiguration information” involved in the embodiments of the present application may refer to the first control information including the pre-configured uplink resource reconfiguration information, or may refer to the downlink data scheduled by the first control information including the pre-configured uplink resource reconfiguration information.

[0109] For another example, one state of the third field indicates that there is no high-layer data and does not include pre-configured uplink resource reconfiguration information, and can also indicate successful transmission. Another state of the third field indicates that there is high-layer data and includes pre-configured uplink resource reconfiguration information, and can also indicate successful transmission. As shown in Table 5-4.

[0110] Table 5-4

[0111]

[0112] Alternatively, the third field may also indicate whether the first information is transmitted through four value states. For example, the first state indicates that the pre-configured uplink resource reconfiguration information is included, and there is high-level data, and it may also indicate successful transmission. The second state indicates that the pre-configured uplink resource reconfiguration information is not included, and there is high-level data, and it may also indicate successful transmission. The third state indicates that the pre-configured uplink resource reconfiguration information is included, and there is no high-level data, and it may also indicate successful transmission. The fourth state indicates that the pre-configured uplink resource reconfiguration information is not included, and there is no high-level data, and it may also indicate successful transmission, as shown in Table 6.

[0113] Table 6

[0114]

[0115]

[0116] In another exemplary description, the second field can indicate whether there is high-layer data through state one and state two, respectively, and the third field can indicate whether it includes pre-configured uplink resource reconfiguration information through state three and state four, respectively. For example, if the second field is in state one and the third field is in state three, it indicates that there is no high-layer data and no pre-configured uplink resource reconfiguration information is included. If the second field is in state one and the third field is in state four, it indicates that there is high-layer data and no pre-configured uplink resource reconfiguration information is included. If the second field is in state two and the third field is in state three, it indicates that there is no high-layer data and pre-configured uplink resource reconfiguration information is included. If the second field is in state two and the third field is in state four, it indicates that there is high-layer data and pre-configured uplink resource reconfiguration information is included. As shown in Table 7-1.

[0117] Table 7-1

[0118]

[0119] In the following, the second field is resource block assignment, and the third field is new data indicator (NDI) as an example. If all bits in resource block assignment are set to 1, it indicates that there is no high-level data. If not all bits in resource block assignment are set to 1, it indicates that there is high-level data. If NDI is in the fifth state, it indicates that pre-configured uplink resource reconfiguration information is included. If NDI is in the sixth state, it indicates that pre-configured uplink resource reconfiguration information is not included, as shown in Table 7-2, or as shown in Table 8.

[0120] Table 7-2

[0121]

[0122] Table 8

[0123]

[0124] It should be understood that Table 7 and Table 8 are merely exemplary descriptions and do not specifically limit the type of the second field, the state of the second field, the type of the third field, the state of the third field, the content of the indication, the correspondence between the state and the content of the indication, etc.

[0125] As a possible implementation manner, the first control information is control information of format N0, the second field may be a subcarrier indication field or an MCS field of the first control information, and the third field may be other fields except the second field, which is not specifically limited.

[0126] As another possible implementation, the first control information is control information of format N1, and the first control information is used to indicate scheduling authorization, and the second field may be the MCS field of the first control information. The third field may be other fields except the second field, which is not specifically limited.

[0127] As another possible implementation, the first control information is control information of format N1, and the first control information is used to indicate a physical control channel instruction, and the second field may be a starting number field of a physical random access channel repetition of the first control information, or a subcarrier indication field of a physical random access channel, or a reserved field. The third field may be other fields except the second field, which is not specifically limited.

[0128] In some embodiments, the first device may indicate the first indication information in the first control information in any of the following ways, but is not limited to:

[0129] Method 1, the uplink and downlink differentiation flag of the first control information can be used, such as Flag format 6-0A / format 6-1A differentiation, or Flag for format N0 / format N1 differentiation. Since the pre-configured resource transmission does not require dynamic DCI for scheduling, when the pre-configured resource transmission is successfully transmitted, generally one or more of ACK, downlink high-layer data and pre-configured uplink resource reconfiguration information is fed back, so the DCI for scheduling downlink data can be used for scheduling. When the pre-configured resource transmission fails, NACK and / or retransmission scheduling information is fed back, so the DCI for scheduling uplink data is used for scheduling. Therefore, the differentiation flag in the downlink control information can be reused as an indication of ACK / NACK, that is, when the flag is 0, it indicates NACK, and when the flag is 1, it indicates ACK, which can save DCI overhead and increase the flexibility of DCI use. Taking Flag format 6-0A / format 6-1A differentiation as an example, the way in which the uplink and downlink differentiation flag indicates the first indication information can be shown in Table 9.

[0130] Table 9

[0131]

[0132] It should be understood that Table 9 is only an exemplary description and does not specifically limit the type of field, the state of the field, the correspondence between the state and the indication content, etc.

[0133] Further, if the first indication information indicates that the pre-configured resource transmission is not successfully transmitted, the first device may also indicate the third information through the first control information, and the third information is used to instruct the second device to perform one or more of the following actions: initiating random access, early data transmission (EDT), NACK, scheduling retransmission, pre-configured resource retransmission, pre-configured resource retransmission and configuration update, for example, as shown in Table 10. Among them, scheduling retransmission may refer to scheduling retransmission through dynamic DCI. In this way, the redundant bit information of the first control information can be further used to instruct the second device to fallback (i.e., instruct the second device to initiate random access or EDT) or pre-configured resource retransmission or pre-configured resource reconfiguration, etc., thereby increasing the probability of successful transmission and improving the flexibility of DCI use.

[0134] Table 10

[0135]

[0136]

[0137] It should be understood that Table 10 is only an exemplary description and does not specifically limit the type of the first field, the state of the first field, the type of the second field, the state of the second field, the indicated content, the correspondence between the state and the indicated content, etc.

[0138] Method 2: If the first control information is control information for users of coverage enhancement mode A or coverage enhancement level 0 or coverage enhancement level 1 (such as format 6-1A, format 6-0A), the first indication information may be indicated by the resource block assignment field. For example, the successful transmission may be indicated by setting all the bits of the resource block assignment field of the DCI (format 6-1A) for scheduling downlink data to 1, and the unsuccessful transmission may be indicated by setting all the bits of the resource block assignment field of the DCI (format 6-0A) for scheduling uplink data to 1.

[0139] If the first control information is control information for users of coverage enhancement mode B or coverage enhancement level 2 or coverage enhancement level 3 (such as format 6-1B, format 6-0B), successful transmission can be indicated by setting all bits of the resource block assignment field of the DCI (format 6-1B) for scheduling downlink data to 1, and unsuccessful transmission can be indicated by setting all bits of the MCS field of the DCI (format 6-0A) for scheduling uplink data to 1. As shown in Table 11.

[0140] Table 11

[0141]

[0142] It should be understood that Table 11 is only an exemplary description and does not specifically limit the type of field, the state of the field, the correspondence between the state and the indication content, etc.

[0143] The above-mentioned method 2 uses the redundant state in the DCI to indicate whether the transmission is correct, which can save DCI overhead and increase the flexibility of DCI use.

[0144] Method three, if the first control information is control information for users of coverage enhancement mode A or coverage enhancement level 0 or coverage enhancement level 1 (such as format 6-1A, format 6-0A), the first indication information can be indicated by the resource block assignment field. For example, all bits of the resource block assignment field in the DCI for scheduling uplink data are set to 1 to indicate successful reception, otherwise it indicates unsuccessful reception. If the first control information is control information for users of coverage enhancement mode B or coverage enhancement level 2 or coverage enhancement level 3 (such as format 6-1B, format 6-0B), the first indication information can be indicated by the MCS field. For example, all bits of the MCS field in the DCI for scheduling uplink data are set to 1 to indicate successful reception, otherwise it indicates unsuccessful reception, as shown in Table 12. In this implementation method, uplink DCI feedback ACK / NACK can be applied. This method uses the redundant state in the DCI to represent whether it is transmitted correctly, which can save DCI overhead and increase the flexibility of DCI use.

[0145] Table 12

[0146]

[0147] It should be understood that Table 12 is only an exemplary description and does not specifically limit the type of field, the state of the field, the correspondence between the state and the indication content, etc.

[0148] In mode 4, the first indication information may be indicated by a bit of the first control information, such as 1 may be used to indicate successful transmission and 0 may be used to indicate unsuccessful transmission. Of course, 0 may be used to indicate successful transmission and 1 may be used to indicate unsuccessful transmission. As shown in Table 13. The bit may be a newly added bit in the first control information or an existing bit in the first control information.

[0149] Table 13

[0150] Bit Instructions First value Successfully received Second value Unsuccessful reception

[0151] Method five, the first indication information may be indicated by two fields. Exemplarily, if the first control information is control information for users of coverage enhancement mode A or coverage enhancement level 0 or coverage enhancement level 1 (such as format 6-1A, format 6-0A), the first field may be a resource block assignment field (or NDI field), and the second field may be a bit in the MCS domain to indicate the first indication information. For example, all bits of the resource block assignment field in the DCI for scheduling uplink data are set to 1 and the bit in the MCS domain is 1, indicating successful transmission (ACK). All bits in the resource block assignment field in the DCI for scheduling uplink data are set to 1 and the bit in the MCS domain is 0, indicating unsuccessful transmission and only NACK, to trigger the second device to perform fallback or PUR retransmission. Other states of the resource block assignment field may indicate unsuccessful transmission and scheduled retransmission. If the first control information is control information for users of coverage enhancement mode B or coverage enhancement level 2 or coverage enhancement level 3 (such as format 6-1B, format6-0B), the first field may be an MCS field (or NDI field), and the second field may be a bit in the repetition number field to indicate the first indication information. For example, all bits of the MCS field in the DCI for scheduling uplink data are set to 1 and the bit in the repetition number field is 1, indicating successful transmission (ACK). All bits in the MCS field in the DCI for scheduling uplink data are set to 1 and the bit in the repetition number field is 0, indicating unsuccessful transmission and only NACK, to trigger the second device to perform fallback or PUR retransmission. Other states of the MCS field may indicate unsuccessful transmission and scheduled retransmission. In this implementation, only uplink DCI feedback ACK / NACK is applicable. This method uses the redundant state in the DCI to indicate whether the transmission is correct, which can save DCI overhead and increase the flexibility of DCI use. As shown in Table 14.

[0152] Table 14

[0153]

[0154]

[0155] It should be understood that Table 14 is only an exemplary description and does not specifically limit the type of the first field, the state of the first field, the type of the second field, the state of the second field, the indicated content, the correspondence between the state and the indicated content, etc.

[0156] In a specific implementation, the second field may also be extended to multiple bits to indicate one or more of initiating random access, EDT, ACK, retransmission of preconfigured resources, and retransmission of preconfigured resources and configuration update, as shown in Table 15, for example.

[0157] Table 15

[0158]

[0159] As a possible implementation, in the above exemplary descriptions, the cyclic redundancy check (CRC) of the first control information may be scrambled by a first scrambling code, wherein the first scrambling code may be a system information radio network temporary identifier (SI-RNTI).

[0160] In some embodiments, in the embodiments of the present application, the first control information may also include configuration information of HARQ-ACK (or PUCCH). The configuration information may include, but is not limited to, one or more of the following information: time-frequency resource information (the time-frequency resource may be configured by two-level configuration, high-level configuration, etc.), feedback time (that is, delay), power control information, number of repetitions, etc. Among them, the time-frequency resource information may be specific resource configuration information, or may be a resource index, etc.

[0164] In combination with the above two specific implementation methods, the second indication information may include: indication information for indicating whether the first information is carried in the physical shared channel scheduled by the first control information; or, the second indication information may also include: indication information for indicating whether the second device detects the second control information, and the second control information is used to schedule the first information; or, the second indication information may also include: indication information for indicating whether the first control information includes pre-configured uplink resource reconfiguration information; or, the second indication information may also include: indication information for indicating whether the second device includes pre-configured uplink resource reconfiguration information in the first control information, and indication information for indicating whether the second device detects third control information, and the third control information is used to schedule the high-level data.
