Description

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

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

[0003] For certain services, the interval between two services is relatively long, and the communication data packets are small. To achieve energy saving and reduce signaling overhead, LTE Release-16 standardized a mechanism for transmission on predefined resources, which means communication that does not require dynamic downlink control information (DCI) scheduling, hence it is also called scheduling-free transmission. The process of uplink scheduling-free transmission is as follows: when a terminal device needs to send uplink data, the network device does not need to perform dynamic uplink scheduling for the terminal device; the terminal device performs uplink transmission on pre-configured transmission resources according to a pre-defined transmission method.

[0004] Currently, after a terminal device performs uplink transmission on preconfigured uplink resource transmission (PUR), the network device can send ACK / NACK information in the PDCCH. ACK indicates successful transmission of the preconfigured resource, while NACK indicates transmission failure. After the network device sends ACK / NACK information, the terminal device needs to continue monitoring for a certain period to see if there is a DCI (Distributed Access Control) scheduling downlink data, and uses this DCI to receive downlink data. Therefore, the terminal device needs to blindly detect the DCI scheduling downlink data during the downlink scheduling process, which increases the power consumption of the terminal device. Summary of the Invention

[0005] This application provides a communication method and device to solve the problem of power consumption waste in the downlink scheduling process of terminal devices in the prior art.

[0006] In a first aspect, embodiments of this application provide a communication method, comprising: a first device determining first control information, the first control information including first indication information and second indication information, wherein the first indication information is used to indicate the status of pre-configured resource transmission, the status including successful transmission, unsuccessful transmission, 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 including higher-layer data and / or reconfiguration information of pre-configured uplink resources; and the first device sending the first control information to a second device. In this embodiment, when the first device reports the status of pre-configured resource transmission to the second device, it indicates whether the second device transmits higher-layer data and / or PUR reconfiguration information, so that the second device can determine whether to receive higher-layer data and / or PUR reconfiguration information when receiving the status of pre-configured resource transmission. Compared to the prior art's method of blindly detecting and scheduling downlink data DCI in the second device, in this embodiment, the first device can notify the second device through the first control information when it does not transmit higher-layer data and / or PUR reconfiguration information, thus the second device does not need to monitor and schedule higher-layer data DCI, reducing the number of blind detections and saving power consumption.

[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 the physical shared channel scheduled by the first control information; or, the second indication information includes: indication information for indicating whether the terminal device detects the second control information, the second control information being 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 the third control information, the third control information being used to schedule the higher-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 from the first control information to indicate the second indication information, it is possible to avoid increasing control information overhead, thereby avoiding reduced spectral efficiency, improving system resource utilization, and avoiding increased user power consumption.

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

[0011] In one possible design, the second indication information can instruct the network device to transmit the first information when all bits in the first field are 1; or, if not all bits in the first field are 1, the second indication information indicates that the network device has not transmitted the first information. Specifically, by reusing the redundant state of the resource block allocation field (i.e., all bits are 1) to indicate the second indication information, it is possible to effectively avoid increasing control information overhead, improve system resource utilization, and enhance the flexibility of DCI usage.

[0012] In one possible design, the first control information is control information of format N0, and the first field can be a subcarrier indication field or a modulation and coding scheme field of the first control information. In the above design, the subcarrier indication field or modulation and coding scheme field in the format N0 control information has some redundant states. By using the redundant states of the subcarrier indication field or modulation and coding scheme field to indicate the second indication information, it is possible to avoid adding bits to the first control information, thereby effectively avoiding increased control information overhead, improving system resource utilization, and enhancing the flexibility of DCI usage.

[0013] In one possible design, the first control information is format N1 control information, and the first control information is used to indicate scheduling authorization. The first field is the modulation and coding scheme field of the first control information. In the above design, the modulation and coding scheme field in the format N1 control information used to indicate scheduling authorization has some redundant states. By using the redundant states of the modulation and coding scheme field to indicate the second indication information, it is possible to avoid adding bits to the first control information, thereby effectively avoiding increased control information overhead, improving system resource utilization, and enhancing the flexibility of DCI usage.

[0014] In one possible design, the first control information is format N1 control information, and the first control information is used to indicate physical control channel commands. The first field can be the starting number field for physical random access channel repetition, the subcarrier indication field for the physical random access channel, or a reserved field. In the above design, the starting number field for physical random access channel repetition or the subcarrier indication field for the physical random access channel in the format N1 control information used to indicate physical control channel commands has some redundancy, 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 increased control information overhead, improving system resource utilization, and enhancing the flexibility of DCI usage.

[0015] In one possible design, the second and third fields of the first control information are used to indicate the second indication information. In the above design, by reusing two fields from the first control information to indicate the second indication information, not only can the overhead of control information be avoided and the system resource utilization improved, but the accuracy of indicating the second indication information can also be enhanced.

[0016] In one possible design, the second field can be a field for allocating the resource block 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.

[0017] In one possible design, the first control information is control information of format N1, and the first control information is used to indicate physical control channel instructions. The second field can be the starting number field of physical random access channel repetition in the first control information, or the subcarrier indication field of physical random access channel, or the reserved field.

[0018] In one possible design, the first control information is control information in format N1, and the first control information is used to indicate scheduling authorization, and the second field can be the modulation and coding scheme field of the first control information.

[0019] In one possible design, the first control information is control information of format N0, and the second field can be the subcarrier indication field or the modulation and coding scheme field of the first control information.

[0020] In one possible design, the cyclic redundancy check (CRC) code of the first control information can be scrambled by a first scrambling code, wherein the first scrambling code can be scrambled by a system information radio network temporary identifier (SI-RNTI).

[0021] Secondly, embodiments of this application provide a communication method, comprising: a second device receiving first control information sent by a first device, the first control information including first indication information and second indication information, wherein the first indication information is used to indicate the status of pre-configured resource transmission, the status including successful transmission, unsuccessful transmission, 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 including higher-layer data and / or PUR reconfiguration information. After determining that the second indication information indicates the first device to transmit the first information, the second device receives the first information according to the second indication information. In this embodiment of the 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 higher-layer data and / or PUR reconfiguration information, so that the second device can determine whether to receive higher-layer data and / or PUR reconfiguration information when receiving the status of pre-configured resource transmission. Compared to the existing technology's method of blindly detecting and scheduling downlink data DCI in the second device, in this embodiment, the first device can notify the second device through the first control information when it is not transmitting higher-layer data and / or PUR reconfiguration information. As a result, the second device does not need to monitor and schedule higher-layer data DCI, which reduces the number of blind detections and saves power consumption.

[0024] 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 from the first control information to indicate the second indication information, it is possible to avoid increasing control information overhead, thereby avoiding reduced spectral efficiency, improving system resource utilization, and avoiding increased user power consumption.

[0025] In one possible design, the first control information is control information in format 6-1A or format 6-1B, and the first field can be a resource block allocation field for the first control information.

[0026] In one possible design, the second indication information can instruct the network device to transmit the first information when all bits in the first field are 1; or, if not all bits in the first field are 1, the second indication information indicates that the network device has not transmitted the first information. Specifically, by reusing the redundant state of the resource block allocation field (i.e., all bits are 1) to indicate the second indication information, it is possible to effectively avoid increasing control information overhead, improve system resource utilization, and enhance the flexibility of DCI usage.

[0027] In one possible design, the first control information is control information of format N0, and the first field can be a subcarrier indication field or a modulation and coding scheme field of the first control information.

The first field is the modulation and coding scheme field of the first control information. In the above design, the modulation and coding scheme field in the format N1 control information used to indicate scheduling authorization has some redundant states. By using the redundant states of the modulation and coding scheme field to indicate the second indication information, it is possible to avoid adding bits to the first control information, thereby effectively avoiding increased control information overhead, improving system resource utilization, and enhancing the flexibility of DCI usage.

[0029] In one possible design, the first control information is format N1 control information, and the first control information is used to indicate physical control channel commands. The first field can be the starting number field for physical random access channel repetition, the subcarrier indication field for the physical random access channel, or a reserved field. In the above design, the starting number field for physical random access channel repetition or the subcarrier indication field for the physical random access channel in the format N1 control information used to indicate physical control channel commands has some redundancy, 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 increased control information overhead, improving system resource utilization, and enhancing the flexibility of DCI usage.

[0046] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0047] The communication method provided in this application can be applied to various communication systems, such as the Internet of Things (IoT), narrowband Internet of Things (NB-IoT), Long Term Evolution (LTE), fifth-generation (5G) communication systems, hybrid LTE and 5G architectures, new radio (NR) systems, global system for mobile communication (GSM), universal mobile telecommunications system (UMTS), code division multiple access (CDMA) systems, and other new communication systems that will emerge in future communication developments. As long as there is one entity in the communication system capable of sending control information for scheduling transport blocks and sending and receiving transport blocks, and another entity capable of receiving control information for scheduling transport blocks and sending and receiving transport blocks, the communication method provided in the embodiments of this application can be used.

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

[0049] The network device involved in this application embodiment can be used to convert received air frames and Internet Protocol (IP) packets to each other, acting as a router between the terminal device and the rest of the access network, which may include IP networks, etc. The network device can also coordinate the attribute management of the air interface. For example, the network device can be a base transceiver station (BTS) in Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB) in Wideband Code Division Multiple Access (WCDMA), an evolved 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 radio base station, a remote radio module, a micro base station, a relay, a distributed unit, a transmission reception point (TRP) or transmission point (TP), or any other wireless access device, but the embodiments of this application are not limited thereto. The network device can cover one or more cells.

[0050] See Figure 1 The diagram illustrates a communication system provided in this application embodiment. This system includes a network device and six terminal devices, namely UE1 to UE6. In this 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. Furthermore, UE4 to UE6 can also form a sub-communication system. The network device can send downlink information to UE1, UE2, UE3, and UE5. UE5 can send downlink information to UE4 and UE6 based on device-to-device (D2D) technology. Figure 1 This is merely a schematic diagram and does not specify 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 this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0052] In a communication system, a UE can be in three states: idle, inactive, and connected. In the connected state, the UE can communicate and transmit data with the base station through dynamic scheduling. However, in the idle state, the UE cannot transmit data through dynamic scheduling; it needs to first perform random access and establish an RRC connection before data transmission can begin, or it may carry a small amount of uplink data in message 3 during the random access process. The inactive state can be seen as an intermediate state between these two. The UE and the core network retain the context of the radio resource control (RRC) messages from the connected state, thus allowing for a faster transition to the connected state compared to the idle state. According to current LTE protocol specifications, when a UE transitions from the RRC connected state to the idle state, the RRC configuration messages are not retained; however, when transitioning from the connected state to the inactive state, the RRC message context is retained.

[0053] For certain services, in order to reduce resource consumption, reduce data transmission latency, and save energy, such as... Figure 2 As shown, services can be transmitted on predefined resources, meaning that dynamic downlink control information (DCI) scheduling is not required; users transmit signals on pre-configured resources. This type of transmission is called configuration-scheduled transmission, also known as pre-configured resource transmission, pre-configured resource scheduling-free transmission, or scheduling-free transmission. Specifically, the pre-configured resources can be pre-configured uplink resources. The process of uplink scheduling-free transmission or pre-configured uplink resource transmission (PUR) is as follows: when a terminal device needs to send uplink data, the network device does not need to dynamically schedule the uplink for the terminal device; the terminal device performs uplink transmission on the pre-configured transmission resources according to a pre-defined transmission method.

[0054] Currently, after a terminal device performs uplink transmission on preconfigured uplink resource transmission (PUR), the network device can send ACK / NACK information in the PDCCH. ACK indicates successful transmission of the preconfigured resource, while NACK indicates transmission failure. After the network device sends ACK / NACK information, the terminal device needs to continue monitoring for a certain period to see if there is a DCI (Distributed Access Control) scheduling downlink data, and uses this DCI to receive downlink data. Therefore, the terminal device needs to blindly detect the DCI scheduling downlink data during the downlink scheduling process, which increases the power consumption of the terminal device.

[0055] Based on this, this application provides a communication method and apparatus to solve the problem of power waste in the downlink scheduling process of terminal devices in the prior art. The method and apparatus are based on the same inventive concept. Since the principles by which the method and apparatus solve the problem are similar, the implementations of the apparatus and method can be mutually referred to, and repeated details will not be elaborated further.

[0056] In the embodiments of this application, "multiple" refers to two or more.

[0057] It should be understood that in the description of this application, the words "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or order.

[0058] See Figure 3 This is a flowchart illustrating a communication method provided in this application. This method can be applied to... Figure 1 The second device in the communication system shown, the method includes:

[0059] S301, the first device determines first control information, the first control information including first indication information and second indication information, wherein the first indication information is used to indicate the 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 including higher layer data and / or PUR reconfiguration information.

[0060] Here, "higher-layer data" can also be called "downlink data," or simply "data," or "downlink higher-layer data." It can be understood that after the second device successfully transmits information to the first device using a pre-configured transmission method, the first and second devices will exchange corresponding information, such as higher-layer ACKs.

[0061] In specific implementations, the first control information may include first indication information, in which case the first control information may not include second indication information. Alternatively, the first control information may include second indication information, in which case the first control information may not include first indication information. Alternatively, the first control information may also include higher-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, scheduled retransmission, or retransmission in pre-configured uplink resources (i.e., NACK).

[0062] It should be noted that the term "preconfigured uplink resource" (PUR) is merely an exemplary designation. Essentially, it refers to a network device configuring this resource so that a second device can transmit uplink information on that resource without requiring dynamic scheduling or downlink control information scheduling by the first device. This resource can also be named by other names, such as "configuration authorized resource." It should be understood that if the configuration authorized resource can also achieve the functionality of the preconfigured uplink resource in this embodiment, it can also be understood as the preconfigured uplink resource in this embodiment. For ease of description, this resource is uniformly referred to as the preconfigured uplink resource in this embodiment.

[0063] Pre-configured resource transmission refers to the second device transmitting data according to pre-defined parameters using pre-configured uplink resources. In this application embodiment, "pre-configured resource transmission" can also be called "pre-configured transmission mode," "scheduling-free transmission," or "pre-configured resource transmission without scheduling," etc. It should be understood that "pre-configured resource transmission" in this application embodiment is merely an illustrative example. In practical applications, "pre-configured resource transmission" can also be named by other names. If such other names can also achieve the function of "pre-configured resource transmission" in this application implementation, they can all be understood as uplink signal transmission according to the pre-configured resource transmission mode. For ease of description, this transmission mode is uniformly referred to as pre-configured resource transmission in this application embodiment.

[0064] Retransmission of pre-configured resources can refer to retransmission within or in part of pre-configured uplink resources. In other words, it does not require dynamic scheduling information (such as DCI) for scheduling, but retransmission is performed through pre-configured uplink resources. However, the configuration information of the corresponding pre-configured resources can be reconfigured or updated through dynamic scheduling information.

[0065] Scheduled retransmission refers to the second device retransmitting data based on the scheduling information (such as DCI) of the first device's dynamic scheduling information.

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

[0067] For example, the first control information can be downlink control information in an LTE eMTC system, downlink control information in an NR system, etc., and is not specifically limited here. For ease of description, the first control information below will be taken as downlink control information (DCI).

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

[0069] It should be noted that in the embodiments of this application, "the first control information schedules the first information", "the first control information schedules the 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 first information being included in the PDSCH scheduled by the first control information.

[0070] Alternatively, the second indication information may also include: indication information for indicating whether the second device detects the second control information, the second control information being used to schedule the first information.

[0071] It should be noted that in the embodiments of this application, "the second device detects the second control information" and "the second device monitors the first search space, the first search space being a search space that carries or transmits the second control information" can both be understood as the second device needing to monitor the second control information.

[0072] Alternatively, the second indication information may also include: indication information for indicating 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, the third control information being used to schedule the higher-layer data.

[0074] It should be noted that in the embodiments of this application, "the second device detects the third control information" and "the second device monitors the second search space, the second search space being a search space that carries or transmits the third control information" can both be understood as the second device needing to monitor the third control information.

[0075] In this configuration, the first device can be a network device, and the second device can be a terminal device. Alternatively, the second device can be a network device, and the first device can be a terminal device. Or, the first device can be a device with transmitting capabilities, and the second device can be a device with receiving capabilities.

[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 specific implementation, the first control information can be one or more control information. If the first control information is a single control information, it includes both a first indication information and a second indication information. If the first control information is multiple control information, one of the control information includes the first indication information, and another control information includes the second indication information. The multiple control information can be sent together, so that the second device can receive the multiple control information together without additional detection.

[0078] S303, after determining that the second instruction information instructs the first device to transmit the first information, the second device receives the first information according to the second instruction information.

[0079] In this embodiment, when the first device reports the status of pre-configured resource transmission to the second device, it instructs the second device whether to transmit higher-layer data and / or pre-configured uplink resource reconfiguration information. Thus, when the second device receives the status of pre-configured resource transmission, it can determine whether to receive higher-layer data and / or pre-configured uplink resource reconfiguration information. Compared to the prior art's method of blindly detecting and scheduling downlink data DCI, in this embodiment, the first device can notify the second device through first control information when it does not transmit higher-layer data and / or pre-configured uplink resource reconfiguration information. This allows the second device to avoid monitoring and scheduling higher-layer data DCI, reducing the number of blind detections and thus saving power consumption.

[0080] For ease of description, in this embodiment, "the PDSCH scheduled by the first control information carries first information," "the first control information schedules the PDSCH," "the first control information indicates the detection of second control information," and "the first control information indicates the monitoring of the first search space" are collectively referred to as "scheduling first information." "The PDSCH scheduled by the first control information carries higher-level data," "the first control information indicates the detection of third control information," "the first control information indicates the monitoring of the second search space," and "the first control information transmits higher-level data" are all referred to as "having higher-level data." "The PDSCH scheduled by the first control information carries PUR reconfiguration information," and "the first control information includes PUR reconfiguration information" are all referred to as "including PUR reconfiguration information."

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

[0082] In one approach, the first control information can indicate the second indication information through a field, such as a first field used to indicate the second indication information. Furthermore, when the first field indicates the second indication information, it can be considered that the pre-configured resource transmission was successful; that is, the first field can indicate both successful transmission of the pre-configured resource and the second indication information.

[0083] In one exemplary embodiment, the first control information can be format 6-1A or format 6-1B control information, and the first field can be the resource block assignment field of the first control information. For example, when all bits in the first field are 1, the second indication information can indicate that the first device has not scheduled PDSCH, or it can indicate successful transmission. If not all bits in the first field are 1, the second indication information can indicate that the first device has scheduled PDSCH, or it can indicate successful transmission (or successful reception). Taking the first information including higher-layer data as an example, as shown in Table 1. In the embodiments of this application, "successful transmission" can also be referred to as "successful reception".

[0084] Table 1

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

[0086] It should be noted that Table 1 is merely an illustrative example, and the status, indication content, and correspondence between status and indication content of the first field are not specifically limited. Alternatively, when all bits in the first field are 1, the second indication information can indicate that the first device is scheduling PDSCH, or it can indicate successful transmission. If not all bits in the first field are 1, the second indication information can indicate that the first device has not scheduled PDSCH, or it can indicate successful transmission.

[0087] In another exemplary embodiment, the first control information is format N0 control information, and the first field can be the subcarrier indication field or the modulation and coding scheme (MCS) field of the first control information. The redundancy status of the subcarrier indication field and the MCS field can be seen in Table 2. For example, with a 3.75kHz subcarrier spacing, a value of 48-63 for the Subcarrier indication field indicates successful reception without PDSCH scheduling. As another example, with a 15kHz subcarrier spacing, a value of 19-63 for the Subcarrier indication field indicates successful reception without PDSCH scheduling. As another example, for a single tone, a value of 11-15 for the MCS field indicates successful reception without PDSCH scheduling. As another example, for a multi-tone, a value of 14 or 15 for the MCS field indicates successful reception without PDSCH scheduling.

[0088] Table 2

[0089]

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

[0091] Table 3

[0092]

[0093] In another exemplary embodiment, the first control information is format N1 control information, and the first control information is used to indicate physical control channel instructions. The first field can be the starting number field for physical random access channel repetition, the subcarrier indication field for physical random access channels, or a reserved field. The redundancy status of the MCS field can be seen in Table 4. For example, a value of 48-63 for the Subcarrier indication of NPRACH field indicates successful reception and no PDSCH scheduling.

[0094] Table 4

[0095]

[0096] In method two, the first control information can indicate the second indication information through two fields, such as the second field and the third field. Specifically, when the first control information indicates the second indication information through the second field and the third field, the PUR transmission can be considered successful; that is, the second field and the third field indicate successful transmission of the pre-configured resource and the second indication information.

[0097] In one exemplary embodiment, the second field can be the resource blockassignment field of the first control information. If all bits in the second field are set to 1, the third field can be used to indicate the second indication information.

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

[0099] Table 5-1

[0100] Third field Instructions A state Successful transmission, no PDSCH scheduled. Another state Successful transmission, with scheduled PDSCH

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

[0102] Table 5-2

[0103] repetition number field Instructions Set all bits to 1 Successful transmission and no PDSCH scheduling

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

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

[0106] Table 5-3

[0107] Third field Instructions A state Successful transmission, including pre-configured uplink resource reconfiguration information. Another state Successful transmission, without including pre-configured uplink resource reconfiguration information.

[0108] The phrase "including pre-configured uplink resource reconfiguration information" in the embodiments of this application may refer to the first control information including pre-configured uplink resource reconfiguration information, or it may refer to the downlink data scheduled by the first control information including pre-configured uplink resource reconfiguration information.

[0109] For example, one status indication in the third field, which shows the absence of higher-layer data and the lack of pre-configured uplink resource reconfiguration information, can also indicate successful transmission. Another status indication in the third field, which shows the presence of higher-layer data and the inclusion of pre-configured uplink resource reconfiguration information, can also indicate successful transmission. See Table 5-4.

[0110] Table 5-4

[0111]

[0112] Alternatively, the third field can also indicate whether the first information was transmitted through four possible states. For example, the first state indicates that pre-configured uplink resource reconfiguration information is included and higher-layer data is available, and can also indicate successful transmission. The second state indicates that pre-configured uplink resource reconfiguration information is not included and higher-layer data is available, and can also indicate successful transmission. The third state indicates that pre-configured uplink resource reconfiguration information is included and higher-layer data is not available, and can also indicate successful transmission. The fourth state indicates that pre-configured uplink resource reconfiguration information is not included and higher-layer data is not available, and can also indicate successful transmission, as shown in Table 6.

[0113] Table 6

[0114]

[0115]

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

[0117] Table 7-1

[0118]

[0119] The following example uses the second field as resource block assignment and the third field as new data indicator (NDI). If all bits in resource block assignment are set to 1, it indicates that there is no higher-layer data; if not all bits in resource block assignment are set to 1, it indicates that there is higher-layer data. If NDI is in state 5, it indicates that pre-configured uplink resource reconfiguration information is included; if NDI is in state 6, it indicates that pre-configured uplink resource reconfiguration information is not included, as shown in Table 7-2 or Table 8.

[0120] Table 7-2

[0121]

[0122] Table 8

[0123]

[0124] It should be understood that Tables 7 and 8 are merely illustrative examples and do not specifically limit the type of the second field, the status of the second field, the type of the third field, the status of the third field, the content indicated, or the correspondence between the status and the content indicated.

[0125] As one possible implementation, the first control information is the control information in format N0, and the second field can be the subcarrier indication field or the MCS field of the first control information. The third field can be any field other than the second field, and there is no specific limitation.

[0126] As another possible implementation, the first control information is the control information of formatN1, and the first control information is used to indicate scheduling authorization. The second field can be the MCS field of the first control information. The third field can be any field other than the second field, and there is no specific limitation.

[0127] As another possible implementation, the first control information is format N1 control information, and the first control information is used to indicate physical control channel instructions. The second field can be the starting number field for physical random access channel repetition in the first control information, or the subcarrier indication field for the physical random access channel, or a reserved field. The third field can be any field other than the second field, and there is no specific limitation.

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

[0129] Method 1 can utilize the uplink / downlink differentiation flag in the first control information, such as Flag format 6-0A / format 6-1A differentiation or Flag for format N0 / format N1 differentiation. Since pre-configured resource transmission does not require dynamic DCI scheduling, when a pre-configured resource transmission is successful, it typically returns one or more of the following: ACK, downlink higher-layer data, and pre-configured uplink resource reconfiguration information. Therefore, the DCI for scheduling downlink data can be used for scheduling. When a pre-configured resource transmission fails, it returns NACK and / or retransmission scheduling information. Therefore, the DCI for scheduling uplink data is used for scheduling. Thus, the differentiation flag in the downlink control information can be reused as an ACK / NACK indicator; that is, a flag of 0 indicates NACK, and a flag of 1 indicates ACK. This saves DCI overhead and increases the flexibility of DCI usage. Taking Flag format 6-0A / format 6-1A differentiation as an example, the way the uplink / 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 merely an illustrative example and does not specify the types of fields, the status of fields, or the correspondence between status and indicated content.

[0133] Furthermore, if the first indication information indicates that the pre-configured resource transmission has failed, the first device can also indicate third information through the first control information. The third information is used to instruct the second device to perform one or more of the following actions: initiate random access, early data transmission (EDT), NACK, scheduled retransmission, pre-configured resource retransmission, or pre-configured resource retransmission with configuration update, as shown in Table 10. Scheduled retransmission can refer to retransmission via dynamic DCI. In this way, redundant bits of the first control information can be used to instruct the second device to fallback (i.e., instruct the second device to initiate random access or EDT), or to retransmit or reconfigure pre-configured resources, thereby increasing the probability of successful transmission and enhancing the flexibility of DCI usage.

[0134] Table 10

[0135]

[0136]

[0137] It should be understood that Table 10 is merely an illustrative example and does not specifically limit the type of the first field, the status of the first field, the type of the second field, the status of the second field, the content indicated, or the correspondence between the status and the content indicated.

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

[0139] If the first control information is for users in coverage enhancement mode B, coverage enhancement level 2, or coverage enhancement level 3 (such as format 6-1B or 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. See Table 11.

[0140] Table 11

[0141]

[0142] It should be understood that Table 11 is merely an illustrative example and does not specifically limit the types of fields, the status of fields, or the correspondence between status and indicated content.

[0143] Method 2 described above uses redundant states in DCI to indicate whether the transmission is correct, which can save DCI overhead and increase the flexibility of DCI usage.

[0144] Method 3: If the first control information is for users in coverage enhancement mode A, coverage enhancement level 0, or coverage enhancement level 1 (e.g., format 6-1A, format 6-0A), the first indication information can be indicated through the resource block assignment field. For example, in the DCI for scheduling uplink data, setting all bits of the resource block assignment field to 1 indicates successful reception, and setting them to 0 indicates unsuccessful reception. If the first control information is for users in coverage enhancement mode B, coverage enhancement level 2, or coverage enhancement level 3 (e.g., format 6-1B, format 6-0B), the first indication information can be indicated through the MCS field. For example, in the DCI for scheduling uplink data, setting all bits of the MCS field to 1 indicates successful reception, and setting them to 0 indicates unsuccessful reception, as shown in Table 12. In this implementation, uplink DCI feedback ACK / NACK can be applied. This method uses redundant states in the DCI to characterize whether the transmission is correct, 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 merely an illustrative example and does not specify the type of fields, the status of fields, or the correspondence between status and indicated content.

[0148] Method four: A single bit in the first control information can be used to indicate the first indication information. For example, a 1 can indicate successful transmission, and a 0 can indicate unsuccessful transmission. Alternatively, a 0 can indicate successful transmission, and a 1 can indicate unsuccessful transmission, as shown in Table 13. This bit can be a newly added bit in the first control information, or it can be an existing bit in the first control information.

[0149] Table 13

[0150] Bit Instructions First value Successfully received Second value Unsuccessfully received

[0151] Method 5: The first indication information can be indicated using two fields. For example, if the first control information is for users in coverage enhancement mode A, coverage enhancement level 0, or coverage enhancement level 1 (such as format 6-1A, format 6-0A), the first field can be the resource block assignment field (or the NDI field), and the second field can be a bit in the MCS field to indicate the first indication information. For instance, if all bits in the resource block assignment field of the DCI for scheduling uplink data are set to 1 and the corresponding bit in the MCS field is 1, it indicates successful transmission (ACK). If all bits in the resource block assignment field of the DCI for scheduling uplink data are set to 1 and the corresponding bit in the MCS field is 0, it indicates unsuccessful transmission and only a NACK, triggering a fallback or PUR retransmission by the second device. Other states in the resource block assignment field can indicate unsuccessful transmission and scheduled retransmission. If the first control information is for users in coverage enhancement mode B, coverage enhancement level 2, or coverage enhancement level 3 (such as format 6-1B, format 6-0B), the first field can be the MCS field (or NDI field), and the second field can be a bit from the repetition number field to indicate the first indication information. For example, in the DCI for scheduling uplink data, all bits of the MCS field are set to 1 and the bit in the repetition number field is 1, indicating successful transmission (ACK). In the DCI for scheduling uplink data, all bits of the MCS field are set to 1 and the bit in the repetition number field is 0, indicating unsuccessful transmission and only NACK, triggering the second device to perform fallback or PUR retransmission. Other states in the MCS field can indicate unsuccessful transmission and scheduled retransmission. In this implementation, only uplink DCI feedback ACK / NACK is applicable. This method uses redundant states 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 merely an illustrative example and does not specifically limit the type of the first field, the status of the first field, the type of the second field, the status of the second field, the content indicated, or the correspondence between the status and the content indicated.

[0156] In practice, the second field can be expanded to multiple bits to indicate one or more of the following: random access, EDT, ACK, pre-configured resource retransmission, and pre-configured resource retransmission with configuration update. For example, as shown in Table 15.

[0157] Table 15

[0158]

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

[0160] In some embodiments of this application, the first control information may further include HARQ-ACK (or PUCCH) configuration information. This configuration information may include, but is not limited to, one or more of the following: time-frequency resource information (which may be configured through two-level configuration, high-level configuration, etc.), feedback time (i.e., delay), power control information, repetition count, etc. The time-frequency resource information may be specific resource configuration information, or it may be a resource index, etc.

[0161] Based on the same inventive concept as the method embodiments, this application provides a communication device, the structure of which can be as follows: Figure 4 As shown, it includes a processing unit 401 and a transceiver unit 402.

[0162] In one specific embodiment, the device is specifically used to implement Figure 3The function of the first device in the embodiment can be the first device itself, or a chip or chipset within the first device, or a part of a chip used to perform related method functions. Specifically, the processing unit 401 is used to determine first control information, which includes first indication information and second indication information. The first indication information is used to indicate the status of pre-configured resource transmission, including successful transmission, unsuccessful transmission, scheduled retransmission, or retransmission within pre-configured resources. The second indication information is used to indicate whether the first device should transmit first information, which includes higher-layer data and / or reconfiguration information of pre-configured uplink resources. The transceiver unit 402 is used to send the first control information determined by the processing unit 401 to the second device.

[0163] In another specific embodiment, the device is specifically used to implement Figure 3 The function of the second device in the embodiment can be the second device itself, or a chip or chipset within the second device, or a part of a chip used to perform related method functions. Specifically, the transceiver unit 402 is used to receive data. The processing unit 401 is used to control the transceiver unit 402 to receive first control information sent by the first device. The first control information includes first indication information and second indication information. The first indication information is used to indicate the status of pre-configured resource transmission, including successful transmission, unsuccessful transmission, scheduled retransmission, or retransmission in pre-configured resources. The second indication information is used to indicate whether the first device should transmit first information, which includes higher-layer data and / or reconfiguration information of pre-configured uplink resources. After determining that the second indication information indicates that the first device should transmit the first information, the transceiver unit 402 is controlled to receive the first information according to the second indication information.

[0164] In combination with the two specific implementations described above, 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, the second control information being 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 the third control information, the third control information being used to schedule the higher-layer data.

[0165] For example, the first field of the first control information can be used to indicate the second indication information.

[0166] In one exemplary embodiment, the first control information is control information in format 6-1A or format 6-1B, and the first field can be a resource block allocation field of the first control information.

[0167] In another exemplary description, when all bits in the first field are 1, the second indication information can instruct the first device to transmit the first information; or, when not all bits in the first field are 1, the second indication information can instruct the first device not to transmit the first information.

[0168] In another exemplary embodiment, the first control information is control information of format N0, and the first field can be the subcarrier indication field or the modulation and coding scheme field of the first control information.

[0169] In another exemplary embodiment, the first control information is control information of format N1, and the first control information is used to indicate scheduling authorization, and the first field can be the modulation and coding scheme field of the first control information.

[0170] In other exemplary descriptions, the first control information is control information of format N1, and the first control information is used to indicate physical control channel instructions. The first field may be the starting number field of physical random access channel repetition, or the subcarrier indication field of physical random access channel, or the reserved field of the first control information.

[0171] For example, the second and third fields of the first control information are used to indicate the second indication information.

[0172] In one exemplary embodiment, the second field can 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.

[0173] In one implementation, the CRC of the first control information can be scrambled by SI-RNTI.

[0174] The module division in this embodiment is illustrative and represents only one logical functional division. In actual implementation, other division methods may be used. Furthermore, the functional modules in each embodiment of this application can be integrated into a single processor, exist as separate physical entities, or be integrated into a single module. The integrated modules described above can be implemented in hardware or as software functional modules.

[0175] When the integrated module is implemented in hardware, the communication device can be as follows: Figure 5 As shown, the processing unit 401 can be a processor 502. The processor 502 can be a CPU, a digital processing module, etc. The transceiver unit 402 can be a communication interface 501, which can be a transceiver, an interface circuit such as a transceiver circuit, or a transceiver chip, etc. The network device also includes a memory 503 for storing the program executed by the processor 801. The memory 503 can be non-volatile memory, such as an HDD or SSD, or volatile memory, such as RAM. The memory 503 can be any other medium capable of carrying or storing desired program code in the form of instructions or data structures that can be accessed by a computer, but is not limited to this.

[0176] The processor 502 is used to execute the program code stored in the memory 503, specifically to perform the actions of the processing unit 401 mentioned above, which will not be described in detail here.

[0177] This application embodiment does not limit the specific connection medium between the communication interface 501, processor 502, and memory 503. This application embodiment...
