Description

[0001] This application claims priority to the PCT patent application filed with the State Intellectual Property Office on September 29, 2019, with application number PCT / CN2019 / 109248 and application name “Communication Methods, Devices and Systems”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to communication methods, devices and systems. Background Art

[0003] The Internet of Things (IoT) is the "Internet of Things". It extends the user end of the Internet to any object, allowing information exchange and communication between any object. This type of communication is also called machine type communications (MTC).

[0004] In release (Rel) 16 of the narrowband internet of things (NB-IoT) system, in order to enable the NB-IoT system and the new radio (NR) system to better share spectrum resources, the coexistence of the NB-IoT system and the NR system was discussed, and it was finally determined that the NB-IoT system can reserve resources, and the reserved resources can be used for scheduling by the NR system.

[0005] However, there is currently no solution on how to reserve resources. Summary of the invention

[0006] The embodiments of the present application provide a communication method, device, and system, which can avoid conflicts between reference signals of a terminal device and data of other terminal devices when reserving resources, thereby avoiding impact on the channel estimation performance of the terminal device.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In the first aspect, a communication method and a corresponding communication device are provided. In this scheme, a terminal device receives resource configuration information from a network device, and determines a symbol corresponding to a first resource in a first time unit based on the resource configuration information. The symbol corresponding to the first resource does not include a symbol where a reference signal is located in the first time unit, and the first resource is not used for data transmission corresponding to the terminal device. Based on this scheme, when reserving resources, the symbol where the reference signal is located is not used as the symbol corresponding to the first resource, so the network device will not perform data scheduling of other terminal devices in the symbol where the reference signal is located, thereby avoiding conflicts between the reference signal of the terminal device and the data transmission of other terminal devices, and further avoiding the impact on the channel estimation performance of the terminal device.

[0009] In one possible design, the resource configuration information includes indication information corresponding to n symbols other than the symbol where a reference signal is located in a first time unit, wherein the indication information corresponding to the first symbol is used to indicate whether the first symbol is a symbol corresponding to a first resource, and the first symbol is one of the n symbols, where n is a positive integer.

[0010] In this scheme, since the resource configuration information will not indicate whether the symbol where the reference signal is located is the symbol corresponding to the first resource, it is impossible for the terminal device to determine that the symbol where the reference signal is located is the symbol corresponding to the first resource based on the resource configuration information. Therefore, it can be achieved that the symbol corresponding to the first resource does not include the symbol where the reference signal is located.

[0011] In one possible design, the resource configuration information includes a first time unit including m symbols, and the resource configuration information includes indication information corresponding to the m symbols, wherein the indication information corresponding to the second symbol is used to indicate whether the second symbol is the symbol corresponding to the first resource, the second symbol is one of the m symbols, and m is a positive integer; the terminal device determines the symbol corresponding to the first resource in the first time unit according to the resource configuration information, including: if the second symbol is the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource does not include the second symbol; if the second symbol is not the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource includes the second symbol.

[0012] In this scheme, even if the resource configuration information indicates that the symbol where the reference signal is located is the symbol corresponding to the first resource, the terminal device does not determine the symbol where the reference signal is located as the symbol corresponding to the first resource. It can also be understood that the terminal device ignores the indication, so that the terminal device can determine that the symbol corresponding to the first resource determined by the resource configuration information does not include the symbol where the reference signal is located.

[0013] In one possible design, the first time unit includes m symbols, and the resource configuration information includes indication information corresponding to the m symbols, wherein the indication information corresponding to the third symbol is used to indicate whether the third symbol is the symbol corresponding to the first resource, the third symbol is one of the m symbols, and m is a positive integer; the terminal device determines the symbol corresponding to the first resource in the first time unit according to the resource configuration information, including: if the third symbol is the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the terminal device adjusts the symbol where the reference signal is located from the third symbol to the fourth symbol, and determines that the symbol corresponding to the first resource includes the third symbol; if the third symbol is not the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource includes the third symbol.

[0014] In this scheme, if the resource configuration information indicates that the symbol where the reference signal is located is the symbol corresponding to the first resource, the terminal device can adjust the symbol where the reference signal is located to a symbol that is not a symbol corresponding to the first resource as indicated by the resource configuration information, thereby enabling the terminal device to determine that the symbol corresponding to the first resource according to the resource configuration information does not include the symbol where the reference signal is located.

[0015] In one possible design, the m symbols include a fifth symbol, the fifth symbol is the symbol where the reference signal is located, and the indication information corresponding to the fifth symbol indicates that the fifth symbol is not the symbol corresponding to the first resource; the communication method also includes: the terminal device adjusts the symbol where the reference signal is located from the fifth symbol to the sixth symbol, and the interval between the fifth symbol and the sixth symbol is equal to the interval between the third symbol and the fourth symbol.

[0016] In this scheme, since the terminal device can adjust the symbol where the reference signal is located from the fifth symbol to the sixth symbol accordingly, it can ensure that the position between at least two symbols where the reference signal is located remains unchanged before the adjustment, thereby avoiding the position jump of the reference signal, and further ensuring that the channel estimation can adopt a set of filtering parameters, thereby reducing the implementation complexity of the channel estimation.

[0017] In one possible design, the communication method also includes: the terminal device receives first indication information from the network device, the first indication information includes a bias value, and the bias value represents the interval between the third symbol and the fourth symbol; or, the first indication information includes position information of the fourth symbol.

[0018] In one possible design, the communication method also includes: the terminal device discards data carried by the symbol corresponding to the first resource.

[0019] In one possible design, the reference signal includes one or more of the following: a narrowband reference signal NRS, a narrowband positioning reference signal NPRS, a demodulation reference signal DMRS, or a cell reference signal CRS.

[0020] In one possible design, the resource configuration information is determined based on a first subcarrier spacing, where the first subcarrier spacing is the largest subcarrier spacing among P subcarrier spacings supported by uplink transmission of the first communication system to which the terminal device accesses, and P is a positive integer greater than or equal to 2. Based on this scheme, since the larger the subcarrier spacing, the shorter the duration of a symbol corresponding to the subcarrier spacing, when the terminal device uses a larger subcarrier for uplink transmission, the resource configuration information is determined according to the larger subcarrier, so that the reserved resources can be more refined.

[0021] In a second aspect, a communication method and a corresponding communication device are provided. In this solution, a network device determines resource configuration information and sends the resource configuration information to a terminal device. The resource configuration information is used by the terminal device to determine a symbol corresponding to a first resource in a first time unit, and the symbol corresponding to the first resource does not include a symbol where a reference signal is located in the first time unit, and the first resource is not used for data transmission corresponding to the terminal device. The technical effects brought about by the second aspect can refer to the technical effects brought about by the above-mentioned first aspect, and will not be repeated here.

[0022] In one possible design, the resource configuration information includes indication information corresponding to n symbols in the first time unit except the symbol where the reference signal is located, wherein the indication information corresponding to the first symbol is used to indicate whether the first symbol is the symbol corresponding to the first resource, and the first symbol is one of the n symbols, and n is a positive integer.

[0023] In one possible design, the first time unit includes m symbols, and the resource configuration information includes indication information corresponding to the m symbols, wherein the indication information corresponding to the second symbol is used to indicate whether the second symbol is the symbol corresponding to the first resource, the second symbol is one of the m symbols, and m is a positive integer; the communication method also includes: if the second symbol is the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource does not include the second symbol; if the second symbol is not the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource includes the second symbol.

[0024] Based on this solution, the symbol corresponding to the first resource determined by the network device according to the resource configuration information does not include the symbol where the reference signal is located, and at the same time, the symbol corresponding to the first resource determined by the network device and the terminal device remains consistent.

[0025] In one possible design, the first time unit includes m symbols, and the resource configuration information includes indication information corresponding to the m symbols, wherein the indication information corresponding to the third symbol is used to indicate whether the third symbol is the symbol corresponding to the first resource, the third symbol is one of the m symbols, and m is a positive integer; the communication method also includes: if the third symbol is the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the network device adjusts the symbol where the reference signal is located from the third symbol to the fourth symbol, and determines that the symbol corresponding to the first resource includes the third symbol; if the third symbol is not the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource includes the third symbol.

[0026] Based on this solution, the symbol corresponding to the first resource determined by the network device according to the resource configuration information does not include the symbol where the reference signal is located, and at the same time, the symbol corresponding to the first resource determined by the network device and the terminal device remains consistent.

[0027] In one possible design, the m symbols include a fifth symbol, the fifth symbol is the symbol where the reference signal is located, and the indication information corresponding to the fifth symbol indicates that the fifth symbol is not the symbol corresponding to the first resource; the communication method also includes: the network device adjusts the symbol where the reference signal is located from the fifth symbol to the sixth symbol, and the interval between the fifth symbol and the sixth symbol is equal to the interval between the third symbol and the fourth symbol.

[0028] In one possible design, the communication method also includes: the network device sends first indication information to the terminal device, the first indication information includes an offset value, and the offset value represents the interval between the third symbol and the fourth symbol; or, the first indication information includes position information of the fourth symbol.

[0029] In one possible design, the communication method also includes: the network device discards data carried by the symbol corresponding to the first resource.

[0030] In one possible design, the reference signal includes one or more of the following: a narrowband reference signal NRS, a narrowband positioning reference signal NPRS, a demodulation reference signal DMRS, or a cell reference signal CRS.

[0031] In one possible design, the resource configuration information is determined based on a first subcarrier spacing, where the first subcarrier spacing is the largest subcarrier spacing among P subcarrier spacings supported by uplink transmission of the first communication system to which the terminal device accesses, and P is a positive integer greater than or equal to 2. Based on this scheme, since the larger the subcarrier spacing, the shorter the duration of a symbol corresponding to the subcarrier spacing, when the terminal device uses a larger subcarrier for uplink transmission, the resource configuration information is determined according to the larger subcarrier, so that the reserved resources can be more refined.

In addition, the network device indicates in the DCI that the uplink reserved resources and / or the downlink reserved resources can be used for data transmission of the first communication system, which is more flexible.

[0065] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies or terms of the present application is first given as follows.

[0066] First, IoT:

[0067] IoT is the "Internet of Things". It extends the user end of the Internet to any object, allowing information exchange and communication between any object. This type of communication is also called machine type communications (MTC). Among them, the communication nodes are called IOT terminals or IOT devices. Typical IoT applications include Internet of Vehicles, smart communities, industrial detection and monitoring, smart meter reading, smart grids, smart agriculture, smart transportation, smart homes, and environmental detection.

[0068] Since the Internet of Things needs to be applied in a variety of scenarios, such as from outdoor to indoor, from above ground to underground, many special requirements are put forward for the design of the Internet of Things. For example, since the IOT terminals in some scenarios are used in environments with poor coverage, such as electric meters and water meters, which are usually installed indoors or even in basements where the wireless network signal is very poor, coverage enhancement technology is needed to solve it. Or, since the number of IOT terminals in some scenarios is much larger than the number of devices for human-to-human communication, that is, large-scale deployment is required, it is required to be able to obtain and use IOT terminals at a very low cost. Or, since the data packets transmitted by IOT terminals in some scenarios are very small and are not sensitive to delays, it is required to support low-rate IOT terminals. Or, since in most cases, IOT terminals are powered by batteries, but at the same time in many scenarios, IOT terminals are required to be able to be used for more than ten years without replacing batteries, which requires IOT terminals to work with extremely low power consumption.

[0069] In order to meet the above needs, the mobile communications standardization organization 3rd Generation Partnership Project (3GPP) passed a new research topic at the RAN#62 plenary meeting to study methods to support extremely low complexity and low-cost Internet of Things in cellular networks, and established the project as NB-IoT at the RAN#69 meeting.

[0070] Second, NR:

[0071] In the face of emerging applications such as MTC communications, smart cities, intelligent transportation, unmanned driving, virtual reality (VR) terminal devices, augmented reality (AR), etc., the NR system (also known as the fifth generation (5G) system) will support three major applications: enhanced mobile broadband (eMBB), ultra reliable and low latency communications (URLLC) and massive machine type communications (mMTC). Currently, 3GPP R15 and R16 NR are mainly aimed at eMBB and URLLC applications. Among them, eMBB deals with human-centric usage scenarios involving user access to multimedia content, services and data. eMBB will meet the needs of explosive growth in data traffic and increased number of users, and is committed to providing a better user experience. Compared with the long term evolution (LTE) system (also known as the fourth generation (4G) system), it can support higher speeds and lower latency.

[0072] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Among them, in the description of the present application, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship, for example, A / B can represent A or B; "and / or" in the present application is only a kind of association relationship describing the associated objects, indicating that there can be three relationships, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. And, in the description of the present application, unless otherwise specified, "multiple" refers to two or more than two. "At least one of the following" or its similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit the differences. At the same time, in the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0073] The embodiments of the present application can be applicable to LTE systems, such as NB-IoT systems; they can also be applicable to other wireless communication systems, such as the global system for mobile communication (GSM), the universal mobile telecommunications system (UMTS), the code division multiple access (CDMA) system, the wideband code division multiple access (WCDMA), the 5G network and new network systems for the future, etc., which are not specifically limited in the embodiments of the present application. Among them, the above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited to this. They are uniformly explained here and will not be repeated below. In addition, the term "system" can be interchangeably with "network".

[0074] like Figure 1 As shown, a communication system 10 provided in an embodiment of the present application is provided. The communication system 10 includes a network device 20 and one or more terminal devices 30 connected to the network device 20. Optionally, different terminal devices 30 can communicate with each other.

[0075] by Figure 1 Taking the interaction between the network device 20 shown and any terminal device 30 as an example, in the embodiment of the present application, the network device 20 determines resource configuration information and sends the resource configuration information to the terminal device 30; the terminal device 30 receives the resource configuration information from the network device 20, and determines the symbol corresponding to the first resource in the first time unit according to the resource configuration information, the symbol corresponding to the first resource does not include the symbol where the reference signal is located in the first time unit, and the first resource is not used for the data transmission corresponding to the terminal device 30. Based on this scheme, when reserving resources, the symbol where the reference signal is located is not used as the symbol corresponding to the first resource, so the network device will not perform data scheduling of other terminal devices in the symbol where the reference signal is located, thereby avoiding the reference signal corresponding to the terminal device 30 from conflicting with the data transmission of other terminal devices, and further avoiding the impact of the conflict on the channel estimation performance of the terminal device 30 and the data transmission performance of other terminal devices.

[0092] Wherein, in some embodiments, Figure 2 The functions of the processor 301 can be achieved by Figure 3 The processor 110 in is implemented.

[0093] In some embodiments, Figure 2 The function of the transceiver 303 can be achieved by Figure 3 The antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, etc. are implemented.

[0103] The following will be combined Figures 1 to 3 ,by Figure 1 Taking the interaction between the network device 20 shown and any terminal device 30 as an example, the communication method provided in the embodiment of the present application is described in detail.

[0104] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are merely examples, and other names may be used in specific implementations, and the embodiments of the present application do not impose any specific limitations on this.

[0105] It should be noted that in the embodiments of the present application, unless otherwise specified, "terminal device" refers to a terminal device in the first communication system. The first communication system can be an NB-IoT system, an enhanced machine type communication (eMTC) system, or a long-term evolution of machines (LTE for Machines, LTE-M) system, or an LTE system. They are uniformly described here and will not be repeated in the following embodiments.

[0106] like Figure 4 As shown, a communication method provided in an embodiment of the present application includes the following steps:

[0107] S401. A network device determines resource configuration information.

[0108] The resource configuration information is used by the terminal device to determine a symbol corresponding to a first resource within a first time unit, and the first resource is not used for data transmission corresponding to the terminal device.

[0109] Among them, in the embodiment of the present application, the first resource may also be called a reserved resource, or other name, and the embodiment of the present application does not make any specific limitation on this; the first resource is not used for data transmission corresponding to the terminal device, which can be understood as the first resource being used for scheduling in the second communication system, or the network device can schedule the first resource to the terminal device in the second communication system for use; or the network device can schedule it to other terminal devices in the first communication system for use.

[0110] It should be noted that in an embodiment of the present application, the second communication system may be a communication system other than the above-mentioned first communication system, such as an NR system, and the embodiment of the present application does not specifically limit this.

[0111] Optionally, the "first time unit" in the embodiment of the present application may include: K time slots, or K subframes, or K half frames, or K radio frames (or called frames), or K super frames, and the embodiment of the present application does not make specific limitations on this, where K is a positive integer; the "symbol" in the embodiment of the present application may be: orthogonal frequency division multiple access (orthogonal frequency division multiplexing, OFDM) symbol, or single carrier frequency division multiple access (single carrier frequency division multiple access, SC-FDMA) symbol.

[0112] It should be noted that the time slot, subframe, half frame, radio frame (or frame) and superframe in the embodiments of the present application can refer to the relevant definition in the first communication system, and can also refer to the relevant definition in the second communication system.

[0113] Among them, in different implementations of the embodiments of the present application, the resource configuration information determined by the network device may also be different, specifically:

[0114] In one possible implementation, the resource configuration information determined by the network device includes indication information corresponding to n symbols other than the symbol where the reference signal is located within the first time unit, wherein the indication information corresponding to the first symbol is used to indicate whether the first symbol is a symbol corresponding to the first resource, and the first symbol is one of the n symbols; n is less than m, m is the total number of symbols included in the first time unit, and n and m are both positive integers.

[0115] Among them, the first symbol is one of the n symbols, which can be understood as: the first symbol is any one of the n symbols. For example, if the n symbols are numbered as symbol 0, symbol 1,..., symbol n-1 in chronological order, then the first symbol can be symbol s, where the value set of s is 0, 1,..., n-1.

[0116] Optionally, the indication information corresponding to the n symbols may be in the form of a bitmap, and one bit in the bitmap may represent the indication information corresponding to one symbol, or may represent the indication information corresponding to multiple discrete symbols among the n symbols, or may represent the indication information corresponding to multiple continuous symbols among the n symbols. The embodiments of the present application do not make any specific limitations on this.

[0117] Exemplarily, the first time unit may be a subframe, and the first time unit includes subframe 1, subframe 1 includes 14 symbols, and the symbols where the reference signal is located are the 4th and 11th symbols in subframe 1, that is, n is 12. Figure 5a As shown, the resource configuration information may use a 12-bit bitmap to represent the indication information corresponding to the 12 symbols, wherein one bit represents the indication information corresponding to one symbol, for example, when the bit is "1", it indicates that the symbol corresponding to the bit is the symbol corresponding to the first resource, and when the bit is "0", it indicates that the symbol corresponding to the bit is not the symbol corresponding to the first resource; or Figure 5b As shown, the resource configuration information can use a 6-bit bitmap to represent the indication information corresponding to the 12 symbols, wherein one bit represents the indication information corresponding to 2 consecutive symbols (except the symbol where the reference signal is located), for example, when the bit is "1", it indicates that the two symbols corresponding to the bit are both symbols corresponding to the first resource, and when the bit is "0", it indicates that the two symbols corresponding to the bit are not symbols corresponding to the first resource. In another possible implementation, the first time unit includes m symbols, and the resource configuration information determined by the network device includes the indication information corresponding to the m symbols, wherein the indication information corresponding to the second symbol is used to indicate whether the second symbol is a symbol corresponding to the first resource, and the second symbol is one of the m symbols; or, the indication information corresponding to the third symbol is used to indicate whether the third symbol is a symbol corresponding to the first resource, and the third symbol is one of the m symbols, and m is a positive integer.

[0118] Among them, the second symbol or the third symbol is one of the m symbols, which can be understood as: the second symbol or the third symbol is any one of the m symbols. For example, if the m symbols are numbered as symbol 0, symbol 1,..., symbol m-1 in chronological order, then the second symbol can be symbol t1, and the third symbol can be symbol t2, where the value sets of t1 and t2 are both 0, 1,..., m-1.

[0119] Optionally, the indication information corresponding to the m symbols may be in the form of a bitmap, and one bit in the bitmap may represent the indication information corresponding to one symbol, or may represent the indication information corresponding to multiple discrete symbols among the m symbols, or may represent the indication information corresponding to multiple continuous symbols among the m symbols. The embodiment of the present application does not make any specific limitation on this.

[0120] Exemplarily, the first time unit may be a subframe, and the first time unit includes subframe 1, subframe 1 includes 14 symbols, that is, m is 14, and the symbols where the reference signal is located are the 4th and 11th symbols in subframe 1. Figure 6a As shown, the resource configuration information may use a 14-bit bitmap to represent the indication information corresponding to the 14 symbols, wherein one bit represents the indication information corresponding to one symbol, for example, when the bit is "1", it indicates that the symbol corresponding to the bit is the symbol corresponding to the first resource, and when the bit is "0", it indicates that the symbol corresponding to the bit is not the symbol corresponding to the first resource; or Figure 6b As shown, the resource configuration information can use a 7-bit bitmap to represent the indication information corresponding to the 14 symbols, wherein one bit represents the indication information corresponding to 2 consecutive symbols. For example, when the bit is "1", it indicates that the two symbols corresponding to the bit are both symbols corresponding to the first resource. When the bit is "0", it indicates that the two symbols corresponding to the bit are not symbols corresponding to the first resource.

[0121] S402: The network device sends resource configuration information to the terminal device. Correspondingly, the terminal device receives the resource configuration information from the network device.

[0122] Optionally, the network device may carry resource configuration information through one or more of downlink control information (DCI), MAC control element (CE), MAC protocol data unit (PDU), or radio resource control (RRC) signaling.

[0123] S403: The terminal device determines a symbol corresponding to the first resource according to the resource configuration information.

[0124] The symbol corresponding to the first resource does not include the symbol where the reference signal is located in the first time unit.

[0125] Optionally, the reference signal includes one or more of the following: a narrowband reference signal (NRS), a narrowband positioning reference signal (NPRS), a demodulation reference signal (DMRS), or a cell-specific reference signal (CRS).

[0126] Among them, NRS and NPRS are reference signals in the NB-IoT system, CRS and PRS are reference signals in the LTE system and eMTC or LTE-M system, and DMRS can be a reference signal in NB-IoT, a reference signal in the LTE system, a reference signal in the eMTC or LTE-M system, or a demodulation reference signal for different physical channels in the NR system.

[0127] Among them, in different implementations of the embodiments of the present application, according to different resource configuration information, the method in which the terminal device determines the symbol corresponding to the first resource according to the resource configuration information may also be different, specifically:

[0128] In a possible implementation, when the resource configuration information includes indication information corresponding to n symbols other than the symbol where a reference signal is located within a first time unit, the terminal device determines the symbol corresponding to the first resource based on the resource configuration information, which may include: if the indication information corresponding to the first symbol indicates that the first symbol is a symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource includes the first symbol; if the indication information corresponding to the first symbol indicates that the first symbol is not a symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource does not include the first symbol, wherein the first symbol is one of the n symbols.

[0129] For example, Figure 5a As shown, the terminal device can determine, according to the resource configuration information, that the symbol corresponding to the first resource includes: the 1st and 6th symbols of subframe 1; Figure 5b As shown, the terminal device can determine, based on the resource configuration information, that the symbols corresponding to the first resource include: the 1st, 2nd, 13th and 14th symbols of subframe 1.

[0130] In this scheme, since the resource configuration information will not indicate whether the symbol where the reference signal is located is the symbol corresponding to the first resource, it is impossible for the terminal device to determine that the symbol where the reference signal is located is the symbol corresponding to the first resource based on the resource configuration information. Therefore, it can be achieved that the symbol corresponding to the first resource does not include the symbol where the reference signal is located.

[0131] It should be noted that, in this implementation, the network device may also determine the symbol corresponding to the first resource in the same manner as the terminal device.

[0132] In another possible implementation, the first time unit includes m symbols, and when the resource configuration information determined by the network device includes indication information corresponding to the m symbols, the terminal device determines the symbol corresponding to the first resource based on the resource configuration information, which may include: if the second symbol is the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource does not include the second symbol; if the second symbol is not the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource includes the second symbol, wherein the second symbol is one of the m symbols.

[0133] For example, Figure 6a As shown, the indication information corresponding to the first symbol of subframe 1 indicates that the first symbol is the symbol where the reference signal is located, and the first symbol is not the symbol where the reference signal is located, so the terminal device determines that the symbol corresponding to the first resource includes the first symbol of subframe 1; the indication information corresponding to the fourth symbol of subframe 1 indicates that the fourth symbol is the symbol where the reference signal is located, and the fourth symbol is the symbol where the reference signal is located, so the terminal device determines that the symbol corresponding to the first resource does not include the fourth symbol of subframe 1, and so on. The terminal device can finally determine that the symbol corresponding to the first resource includes the first and sixth symbols of subframe 1 according to the resource configuration information.

[0134] In this scheme, even if the resource configuration information indicates that the symbol where the reference signal is located is the symbol corresponding to the first resource, the terminal device does not determine the symbol where the reference signal is located as the symbol corresponding to the first resource. It can also be understood that the terminal device ignores the indication, so that the terminal device can determine that the symbol corresponding to the first resource determined by the resource configuration information does not include the symbol where the reference signal is located.

[0135] It should be noted that in this implementation, the network device can also determine the symbol corresponding to the first resource in the same manner as the network device, that is, if the second symbol is the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource does not include the second symbol; if the second symbol is not the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource includes the second symbol. Based on this scheme, it can be achieved that the symbol corresponding to the first resource determined by the network device according to the resource configuration information does not include the symbol where the reference signal is located, and at the same time, the symbol corresponding to the first resource determined by the network device and the terminal device remains consistent.

[0136] In another possible implementation, the first time unit includes m symbols, and when the resource configuration information determined by the network device includes indication information corresponding to the m symbols, the terminal device determines the symbol corresponding to the first resource based on the resource configuration information, which may include: if the third symbol is the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the terminal device adjusts the symbol where the reference signal is located from the third symbol to the fourth symbol, and determines that the symbol corresponding to the first resource includes the third symbol; if the third symbol is not the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the terminal device determines that the symbol corresponding to the first resource includes the third symbol, wherein the third symbol is one of the m symbols.

[0137] Optionally, the fourth symbol may be a symbol indicated by the resource configuration information that is not a symbol corresponding to the first resource.

[0138] For example, Figure 7a As shown, the first symbol of subframe 1 is not the symbol where the reference signal is located, and the corresponding indication information indicates that the first symbol is the symbol corresponding to the first resource, so the terminal device determines that the symbol corresponding to the first resource includes the first symbol of subframe 1; the fourth symbol of subframe 1 is the symbol where the reference signal is located, and the indication information corresponding to the fourth symbol indicates that the fourth symbol is the symbol where the reference signal is located, so the terminal device adjusts the symbol where the reference signal is located from the fourth symbol to the third symbol (i.e., the fourth symbol), and determines that the symbol corresponding to the first resource includes the fourth symbol of subframe 1, and so on. The terminal device can finally determine that the symbols corresponding to the first resource include the first, fourth and sixth symbols of subframe 1 according to the resource configuration information.

[0139] In this scheme, if the resource configuration information indicates that the symbol where the reference signal is located is the symbol corresponding to the first resource, the terminal device can adjust the symbol where the reference signal is located to a symbol that is not a symbol corresponding to the first resource as indicated by the resource configuration information, thereby enabling the terminal device to determine that the symbol corresponding to the first resource according to the resource configuration information does not include the symbol where the reference signal is located.

[0140] It should be noted that in this implementation, the network device can also determine the symbol corresponding to the first resource in the same way as the network device, that is, if the third symbol is the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the network device adjusts the symbol where the reference signal is located from the third symbol to the fourth symbol, and determines that the symbol corresponding to the first resource includes the third symbol; if the third symbol is not the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the network device determines that the symbol corresponding to the first resource includes the third symbol. Based on this scheme, it can be achieved that the symbol corresponding to the first resource determined by the network device according to the resource configuration information does not include the symbol where the reference signal is located, and at the same time, the symbol corresponding to the first resource determined by the network device and the terminal device remains consistent.

[0141] Optionally, in this implementation, the network device may send the first indication information to the terminal device. Accordingly, the terminal device receives the first indication information from the network device. The first indication information includes an offset value, which identifies the interval between the third symbol and the fourth symbol. The unit of the interval may be a symbol or other time domain unit; or the first indication information includes the position information of the fourth symbol. For example, based on the above Figure 7a In the example shown, the first indication information may include a bias value of 1, indicating that the interval between the third symbol and the fourth symbol is 1 symbol; or, the first indication information may include position information of the third symbol of subframe 1, for example, the identifier of the third symbol, indicating that the symbol where the reference signal is located is adjusted from the fourth symbol to the third symbol.

[0142] Among them, the network device can first determine the symbol corresponding to the first resource and then send the first indication information to the terminal device, or it can first send the first indication information to the terminal device and then determine the symbol corresponding to the first resource in combination with the first indication information and the resource configuration information. The embodiment of the present application does not make specific limitations on this.

[0143] Optionally, in this implementation, if the m symbols included in the first time unit include the fifth symbol, the fifth symbol is the symbol where the reference signal is located, and the indication information corresponding to the fifth symbol indicates that the fifth symbol is not the symbol corresponding to the first resource, the communication method provided in the embodiment of the present application also includes: the terminal device adjusts the symbol where the reference signal is located from the fifth symbol to the sixth symbol, the interval between the fifth symbol and the sixth symbol is equal to the interval between the third symbol and the fourth symbol, and the adjustment direction from the fifth symbol to the sixth symbol is consistent with the adjustment direction from the third symbol to the fourth symbol. For example, if the symbol where the reference signal is located is adjusted forward from the third symbol to the fourth symbol, the symbol where the reference signal is located is adjusted forward from the fifth symbol to the sixth symbol; if the symbol where the reference signal is located is adjusted backward from the third symbol to the fourth symbol, the symbol where the reference signal is located is adjusted backward from the fifth symbol to the sixth symbol.

[0144] For example, based on Figure 7a In the example shown, the 11th symbol of subframe 1 is the symbol where the reference signal is located, and the indication information corresponding to the 11th symbol indicates that the 11th symbol is not the symbol corresponding to the first resource, then the terminal device adjusts the symbol where the reference signal is located from the 11th symbol to the 10th symbol, such as Figure 7b As shown, the symbols where the adjusted reference signal is located are the 3rd symbol and the 10th symbol of subframe 1.

[0145] In this scheme, since the terminal device can adjust the symbol where the reference signal is located from the fifth symbol to the sixth symbol accordingly, it can ensure that the position between at least two symbols where the reference signal is located remains unchanged before the adjustment, thereby avoiding the position jump of the reference signal, and further ensuring that the channel estimation can adopt a set of filtering parameters, thereby reducing the implementation complexity of the channel estimation.

[0146] It should be noted that, in this implementation, the network device may also adjust the fifth symbol to the sixth symbol so that the symbol of the reference signal determined by the network device and the terminal device remains consistent.

[0147] Optionally, after the terminal device and the network device determine the symbol corresponding to the first resource, when data is subsequently transmitted between the terminal device and the network device, the terminal device and the network device discard (or delete) the data carried by the symbol corresponding to the first resource. In other words, the symbol corresponding to the first resource is calculated during resource mapping but is not used for data transmission.

[0148] It should be noted that the data carried by the symbols corresponding to the first resource should be discarded or deleted before data transmission. The terminal device and the network device take the first resource into account when mapping resources, but the data carried by the symbols corresponding to the first resource is discarded (or deleted) and not used for data transmission.

[0149] Exemplarily, there are 5 symbols in the first time unit for data transmission between the terminal device and the network device, wherein the 3rd symbol is configured as the symbol corresponding to the first resource. The terminal device and the network device take the symbol corresponding to the first resource into account when mapping the resources. If the resource mapped data is {a, b, c, d, e}, and a, b, c, d, e are mapped to the 5 symbols in sequence, then the data c on the 3rd symbol occupied by the first resource is discarded (or deleted) before data transmission, and the data actually transmitted by the terminal device and the network device is {a, b, d, e}.

[0150] In summary, based on the communication method provided in the embodiment of the present application, when reserving resources, the symbol where the reference signal is located is not used as the symbol corresponding to the first resource. Therefore, the network device will not schedule data of other terminal devices in the symbol where the reference signal is located, thereby avoiding conflicts between the reference signal corresponding to the terminal device and the data transmission of other terminal devices, and further avoiding the impact of conflicts on the channel estimation performance of the terminal device and the data transmission performance of other terminal devices.

[0151] It should be noted that in the embodiment of the present application, the terminal device and the network device can use the first time unit as a period and determine the symbol corresponding to the first resource in each first time unit according to the above resource configuration information. The starting position of each first time unit can be determined according to at least one of the frame number, subframe number, time slot number or symbol number. For example, the starting frame of the first time unit is a frame that satisfies SFN mod x = 0, SFN is the frame number, x is a preset value, and x is a positive integer. For example, Figure 8 As shown, the diagram includes 4 first time units. If the above resource configuration information is "00010000010000", the terminal device and the network device determine the symbol corresponding to the first resource in each of the four first time units according to the resource configuration information.

[0152] It should be noted that in an embodiment of the present application, within a second time unit including multiple first time units, the network device may send resource configuration information to the terminal device only once, and the terminal device and the network device may determine the symbol corresponding to the first resource in the second time unit based on the resource configuration information.

[0153] Exemplarily, the network device may send second indication information to the terminal device, and the second indication information includes indication information corresponding to each first time unit included in the second time unit, and the indication information corresponding to the first time unit may indicate whether it is necessary to determine the symbol corresponding to the first resource in the first time unit according to the resource configuration information. The starting position of each second time unit may be determined according to at least one of the frame number, subframe number, time slot number or symbol number. For example, the starting frame of the second time unit is a frame that satisfies SFN mod y=0, SFN is the frame number, y is a preset value, and y is a positive integer.

[0154] For example, Fig. 9 As shown, the second time unit includes 4 first time units, and the indication information corresponding to the 4 first time units is respectively "1001", wherein "1" indicates that it is necessary to determine the symbol corresponding to the first resource in the first time unit according to the resource configuration information, and "0" indicates that it is not necessary to determine the symbol corresponding to the first resource in the first time unit according to the resource configuration information, that is to say, it indicates that there is no symbol corresponding to the first resource in the first time unit. Therefore, the terminal device and the network device determine the symbol corresponding to the first resource in the first first time unit and the fourth first time unit included in the second time unit according to the resource configuration information.

[0155] Optionally, in an implementation scenario of an embodiment of the present invention, for a first communication system that supports P seed carrier spacing for uplink transmission accessed by a terminal device, since the larger the subcarrier spacing, the shorter the duration of a symbol corresponding to the subcarrier spacing, when the network device determines the resource configuration information in the above step S401, the resource configuration information can be determined according to the first subcarrier spacing, which can also be understood as the network device configuring the resource configuration information according to the first subcarrier spacing, that is, the resource configuration information is determined according to the first subcarrier spacing, or the resource configuration information is configured according to the first subcarrier. Wherein, P is a positive integer greater than or equal to 2, and the first subcarrier spacing is the largest subcarrier spacing in the P seed carrier spacing, that is, the network device reserves resources according to the largest subcarrier spacing, and at this time, more refined resource reservation can be achieved.

[0156] For example, taking the first communication system as the NB-IoT system, the terminal device can use a subcarrier spacing of 3.75kHz or a subcarrier spacing of 15kHz during uplink transmission. At this time, the network device can determine the resource configuration information based on the subcarrier spacing of 15kHz. In addition, if the NB-IoT system coexists with the NR system, since the minimum subcarrier spacing currently supported by the NR system is 15kHz, at this time, reserving resources at 15kHz in the NB-IoT system can better realize dynamic resource sharing with the NR system.

[0157] In this scenario, accordingly, in step S402, the resource configuration information received by the terminal device is the resource configuration information determined by the network device according to the first subcarrier spacing. In step S403, the terminal device determines the symbol corresponding to the first resource under the second subcarrier spacing in combination with the resource configuration information and the second subcarrier spacing, wherein the second subcarrier spacing is the subcarrier spacing actually used by the terminal device for uplink transmission, and the second subcarrier spacing is configured by the network device.

[0158] In a possible implementation, when the second subcarrier spacing is the same as the first subcarrier spacing, the terminal device performs the above Figure 4 The method in the embodiment shown determines the symbol corresponding to the first resource under the second subcarrier spacing; when the second subcarrier spacing is smaller than the first subcarrier spacing, the terminal device needs to determine the symbol corresponding to the first resource under the second subcarrier spacing according to the resource configuration information determined according to the first subcarrier spacing. Among them, since the duration of a symbol corresponding to the first subcarrier spacing is smaller than the duration of a symbol corresponding to the second subcarrier spacing, a symbol that can be used as the first resource under the first subcarrier spacing indicated by the resource configuration information may be included in the duration of a symbol corresponding to the second subcarrier spacing. At this time, when part of the duration of a symbol under the second subcarrier is indicated by the resource configuration information as a symbol corresponding to the first resource under the first subcarrier, the terminal device determines the symbol under the second subcarrier as the symbol corresponding to the first resource under the second subcarrier; when all the durations within the duration of a symbol under the second subcarrier are not indicated by the resource configuration information as the symbol corresponding to the first resource under the first subcarrier, the terminal device determines that the symbol under the second subcarrier is not used as the symbol corresponding to the first resource under the second subcarrier.

[0159] For example, taking the first communication system as a NB-IoT system, the first subcarrier spacing is 15kHz, and the second subcarrier spacing is 3.75kHz, as Fig.12 As shown, the dotted box represents the duration of a symbol corresponding to 15kHz, and the solid box represents the duration of a symbol corresponding to 3.75kHz. If part of the duration of the symbol n corresponding to 3.75kHz is indicated by the resource configuration information as a symbol corresponding to the first resource at 15kHz, the terminal device determines that the symbol n is the symbol corresponding to the first resource at 3.75kHz; and if the entire duration of the symbol n+1 corresponding to 3.75kHz is not indicated by the resource configuration information as a symbol corresponding to the first resource at 15kHz, the terminal device determines that the symbol n+1 is not a symbol corresponding to the first resource at 3.75kHz.

[0160] Based on this solution, since the larger the subcarrier spacing, the shorter the duration of a symbol corresponding to the subcarrier spacing, when the terminal device uses a larger subcarrier for uplink transmission, the resource configuration information is determined according to the larger subcarrier, which can make the reserved resources more refined.

[0161] Optional, such as Fig.13 As shown, another communication method provided in an embodiment of the present application includes the following steps:

[0162] S1301. The network device determines that the second resource is not used for the downlink transmission corresponding to the terminal device, and / or the third resource is not used for the uplink transmission corresponding to the terminal device.

[0163] Specifically, step S1301 may include: the network device determines configuration information, where the configuration information includes first resource configuration information and / or second resource configuration information.

[0164] Among them, the first resource configuration information is used by the terminal device to determine the second time unit corresponding to the second resource within the first time length, and the second resource is not used for the downlink transmission corresponding to the terminal device; the second resource configuration information is used by the terminal device to determine the third time unit corresponding to the third resource within the second time length, and the third resource is not used for the uplink transmission corresponding to the terminal device.

[0165] Among them, when the configuration information includes the first resource configuration information, the network device determines that the second resource is not used for the downlink transmission corresponding to the terminal device; when the configuration information includes the second resource configuration information, the network device determines that the third resource is not used for the uplink transmission corresponding to the terminal device.

[0166] Wherein, the second time unit may be a subframe, or a time slot, or a symbol. Accordingly, when the second time unit is a subframe, the first duration may include: M half frames, or M radio frames (or frames), or M super frames; when the second time unit is a time slot, the first duration may include: M subframes, or M half frames, or M radio frames (or frames), or M super frames; when the second time unit is a symbol, the first duration may include: M time slots, or M subframes, or M half frames, or M radio frames (or frames), or M super frames, where M is a positive integer. Similarly, the third time unit has the same features as the second time unit, and the second duration has the same features as the first duration, and the description of the second time unit and the first duration may be referred to, and will not be repeated here.

[0167] Optionally, the second resource can be called a downlink reserved resource, the third resource can be called an uplink reserved resource, the second resource and the third resource can be collectively referred to as reserved resources, or the second resource and the third resource can also have other names, and the embodiments of the present application do not specifically limit this.

[0168] It should be noted that the second resource is not used for the downlink transmission corresponding to the terminal device, which can be understood as the second resource is used for scheduling in the second communication system, or the network device can schedule the second resource to the terminal device in the second communication system, or the network device can schedule the second resource to other terminal devices in the first communication system, or the network device can schedule the second resource for uplink transmission of the terminal device. The third resource is not used for the uplink transmission corresponding to the terminal device, which can be understood as the third resource is used for scheduling in the second communication system, or the network device can schedule the third resource to the terminal device in the second communication system, or the network device can schedule the third resource to other terminal devices in the first communication system, or the network device can schedule the third resource for downlink transmission of the terminal device. The description of the first communication system and the second communication system can be referred to. Figure 4 The relevant description in the illustrated embodiment will not be repeated here.

[0169] Optionally, when the second time unit and the third time unit are both symbols, the manner in which the network device determines the configuration information, and the related description of the form of the first resource configuration information and the second resource configuration information can refer to the above step S401. When the network device determines the first resource configuration information and / or the second resource configuration information, it can also determine the resource configuration information based on the first subcarrier spacing. The specific implementation method is described in the above embodiment and will not be repeated here.

[0170] S1302: The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information from the network device.

[0171] S1303. The terminal device determines that the second resource is not used for the downlink transmission corresponding to the terminal device, and / or the third resource is not used for the uplink transmission corresponding to the terminal device.

[0172] Specifically, step S1301 may include: when the configuration information includes first resource configuration information, the terminal device determines the second time unit corresponding to the second resource according to the first resource configuration information, and the second resource is not used for the downlink transmission corresponding to the terminal device; when the configuration information includes second resource configuration information, the terminal device determines the third time unit corresponding to the third resource according to the second resource configuration information, and the third resource is not used for the uplink transmission corresponding to the terminal device; when the configuration information includes first resource configuration information and second resource configuration information, the terminal device determines the second time unit corresponding to the second resource according to the first resource configuration information, and the terminal device determines the third time unit corresponding to the third resource according to the second resource configuration information.

[0173] Among them, when the second time unit is a symbol, the second time unit corresponding to the second resource does not include the symbol where the reference signal is located within the first time length; when the third time unit is a symbol, the third time unit corresponding to the third resource does not include the symbol where the reference signal is located within the second time length.

[0174] Among them, the relevant instructions on the reference signal can refer to the description in the above step S403, which will not be repeated here; when the second time unit and the third time unit are symbols, the terminal device determines the second time unit corresponding to the second resource according to the first resource configuration information, and determines the third time unit corresponding to the third resource according to the second resource configuration information. The relevant implementation can refer to the above step S403, where the terminal device determines the symbol corresponding to the first resource according to the resource configuration information, and will not be repeated here.

[0175] S1304: The network device sends downlink control information (DCI) to the terminal device. Correspondingly, the terminal device receives the DCI from the network device.

[0176] The DCI is used to schedule N TBs and feedback information corresponding to the N TBs. The feedback information is used to indicate whether the N TBs are successfully received. The feedback information may be, for example, ACK (acknowledgement) / NACK (negative acknowledgement), where N is a positive integer.

[0177] Optionally, in the NB-IoT system, ACK or NACK feedback information is carried through the narrowband physical uplink shared channel NPUSCH (narrowband physical uplink shared channel) format 2. In the LTE-M system, or the eMTC system, or the LTE system, or the NR system, ACK or NACK feedback information is carried through the physical uplink control channel PUCCH (physical uplink control channel).

[0178] The DCI may include first information, and the first information is used to determine the time-frequency resources for transmitting feedback information corresponding to N transmission blocks (TB) scheduled by the DCI.

[0179] Among them, when the configuration information in the above step S1301 includes the first resource configuration information, the DCI may also include the second information; when the configuration information in the above step S1301 includes the second resource configuration information, the DCI may also include the third information; when the configuration information in the above step S1301 includes the first resource configuration information and the second resource configuration information, the DCI may also include the second information and the third information.

[0180] The second information is used to indicate whether part or all of the second time units corresponding to the second resource can be used during the transmission of the N TBs, that is, when the time domain resources for transmitting the N TBs include part or all of the second time units corresponding to the second resource, whether part or all of the second time units corresponding to the second resource can be used to transmit one or more TBs among the N TBs. The third information is used to indicate whether part or all of the third time units corresponding to the third resource can be used during the transmission of the feedback information corresponding to the N TBs, that is, when the time domain resources indicated by the first information include part or all of the third time units corresponding to the third resource, whether part or all of the third time units corresponding to the third resource can be used to transmit part or all of the feedback information corresponding to the N TBs.

[0181] Optionally, when the network device does not schedule the second resource for use by a terminal device in the second communication system, or does not schedule the second resource for use by other terminal devices in the first communication system, or does not schedule the second resource for uplink transmission of the terminal device, the second information is used to indicate that part or all of the second time units corresponding to the second resource can be used during the transmission of the N TBs.

[0182] Optionally, when the network device does not schedule the third resource for use by a terminal device in the second communication system, or does not schedule the third resource for use by other terminal devices in the first communication system, or does not schedule the third resource for downlink transmission of the terminal device, the third information is used to indicate that part or all of the third time units corresponding to the third resource can be used during the transmission of feedback information corresponding to the N TBs.

[0183] Optionally, the network device may jointly indicate the second information and the third information, for example, the second information and the third information occupy the same field in the DCI, and the field may indicate an index, and different indexes correspond to different second information and third information. For example, when the index is 1, the corresponding second information indicates that part or all of the second time units corresponding to the second resource can be used during the transmission of the N TBs, and the third information indicates that part or all of the third time units corresponding to the third resource can be used during the transmission of feedback information corresponding to the N TBs, etc.; or, the network device may also indicate the second information and the third information separately, for example, the second information and the third information occupy different fields in the DCI, different values ​​of the field occupied by the second information represent different contents of the second information, different values ​​of the field occupied by the third information represent different contents of the third information, etc. The embodiment of the present application does not specifically limit the form of the second information and the third information.

[0184] Optionally, in this embodiment, for the NB-IoT system, the format of the DCI may be format N1; for the LTE-M system, or the eMTC system, the format of the DCI may be format 6-1A, or the format of the DCI may be 6-1B; for the NR system, the format of the DCI may be format 1-0, or format 1-1.

[0185] Optionally, in this embodiment, the cyclic redundancy check (CRC) code of the DCI is scrambled by a cell radio network temporary identifier (C-RNTI) or a semi-persistent scheduling (SPS) C-RNTI.

[0186] Optionally, in this embodiment, for the NB-IoT system, the DCI format containing the second information and / or the third information is mapped to at least one of the following search spaces: narrowband physical downlink control channel (NPDCCH) UE-specific search space (UE-specific search space, USS), type 1 (Type1) NPDCCH common search space (common search space, CSS), Type2 NPDCCH CSS. For the LTE-M system, or the eMTC system, the DCI format containing the second information and / or the third information is mapped to at least one of the following search spaces: MTC physical downlink control channel (MTC physical control channel, MPDCCH) UE-specific search space (UE-specific search space, USS), type 1 (Type1) MPDCCH common search space (common search space, CSS), Type2 MPDCCH CSS, Type0 MPDCCH CSS.

[0187] S1305: The network device sends the N TBs to the terminal device. Correspondingly, the terminal device receives the N TBs.

[0188] In this embodiment of the present application, the second information is used to indicate that part or all of the second time units corresponding to the second resource can be used during the transmission of the N TBs.

[0189] In this case, the network device sends the N TBs to the terminal device by: the network device sends the N TBs to the terminal device on the first time domain resources including part or all of the second time units corresponding to the second resource, wherein the first time domain resources are all time domain resources used to transmit the N TBs.

[0190] Among them, the first time domain resource can be determined according to the scheduling information in the DCI. That is to say, before step S1305, the communication method provided by this embodiment may also include: the terminal device determines the first time domain resource according to the scheduling information. For example, the scheduling information includes the delay between the first moment and the start moment of the N TB transmission, wherein the first moment is the moment after the end moment of the DCI transmission plus T fourth time units, T is a positive integer greater than or equal to 0, and the fourth time unit is a wireless frame (also referred to as a frame), a subframe, a time slot or a symbol. The terminal device can determine the end moment of the DCI transmission, and determine the first time domain resource according to the end moment of the DCI transmission, the delay, and the number of repetitions of the N TB transmissions, wherein the number of repetitions can be configured by the network device and sent to the terminal device.

[0191] Correspondingly, the terminal device receives the N TBs when, according to the second information, the terminal device receives the N TBs from the network device on the first time domain resources including part or all of the second time units corresponding to the second resources.

[0192] S1306: The terminal device sends feedback information corresponding to the N TBs to the network device. Correspondingly, the network device receives feedback information corresponding to the N TBs from the terminal device.

[0193] In this embodiment of the present application, the third information is used to indicate that part or all of the third time units corresponding to the third resource can be used during the transmission of the feedback information corresponding to the N TBs.

[0194] In this case, the terminal device sends feedback information corresponding to the N TBs to the network device, namely: the terminal device sends feedback information corresponding to the N TBs to the network device on the second time domain resources including part or all of the third time units corresponding to the third resources according to the third information.

[0195] It should be noted that, in the embodiment of the present application, the second time domain resource is all the time domain resources used to transmit the feedback information corresponding to the N TBs, and the second time domain resource can be determined according to the first information, that is, before step S1306, the communication method provided in this embodiment may also include: the terminal device determines the second time domain resource according to the first information. For example, the first information may indicate the delay between the end time of the transmission of the N TBs and the start time of the ACK / NACK transmission corresponding to the N TBs. At this time, the terminal device can determine the end time of the transmission of the N TBs, and determine the second time domain resource according to the end time of the transmission of the N TBs, the delay, and the number of repetitions of the ACK / NACK transmission corresponding to the N TBs, wherein the number of repetitions can be configured by the network device and sent to the terminal device.

[0196] Correspondingly, the network device receives the feedback information corresponding to the N TBs from the terminal device, which means that the network device receives the feedback information corresponding to the N TBs from the terminal device on the second time domain resources including part or all of the third time units corresponding to the third resources.

[0197] Based on this solution, when the reserved resources are not used by the second communication system, the DCI can be used to dynamically indicate that the reserved resources can be used for downlink transmission of the first communication system or transmission of feedback information corresponding to downlink data, and then the reserved resources can be used for data transmission of the first communication system to avoid resource waste. In addition, the network device indicates in the DCI that the uplink reserved resources and / or the downlink reserved resources can be used for data transmission of the first communication system, which is more flexible.

[0198] It is understandable that in the embodiment of the present application, the terminal device and / or the network device can perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application can also perform other operations or variations of various operations. In addition, each step can be performed in a different order presented in the embodiment of the present application, and it is possible not to perform all the operations in the embodiment of the present application.

[0199] In the various embodiments of the present application, unless otherwise specified or provided in a logical conflict, the terms and / or descriptions between the different embodiments are consistent and may be referenced to each other, and the technical features in the different embodiments may be combined to form new embodiments according to their inherent logical relationships.

[0200] It can be understood that in the above embodiments, the methods and / or steps implemented by the terminal device can also be implemented by components (such as chips or circuits) that can be used for the terminal device, and the methods and / or steps implemented by the network device can also be implemented by components (such as chips or circuits) that can be used for the network device.

[0201] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of interaction between various network elements. Accordingly, the embodiment of the present application also provides a communication device, which is used to implement the above various methods. The communication device can be a terminal device in the above method embodiment, or a device including the above terminal device, or a component that can be used for a terminal device; or, the communication device can be a network device in the above method embodiment, or a device including the above network device, or a component that can be used for a network device. It can be understood that in order to implement the above functions, the communication device includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0202] The embodiment of the present application can divide the functional modules of the communication device according to the above method embodiment. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0203] For example, take the communication device as the terminal device in the above method embodiment. Fig.10 The schematic diagram of the structure of a terminal device 100 is shown. The terminal device 100 includes a processing module 1001 and a transceiver module 1002. The transceiver module 1002, which may also be called a transceiver unit, is used to implement the sending and / or receiving functions, and may be a transceiver circuit, a transceiver, a transceiver or a communication interface.

[0204] In one possible implementation:

[0205] Among them, the transceiver module 1002 is used to receive resource configuration information from the network device; the processing module 1001 is used to determine the symbol corresponding to the first resource in the first time unit according to the resource configuration information, the symbol corresponding to the first resource does not include the symbol where the reference signal in the first time unit is located, and the first resource is not used for data transmission corresponding to the communication device.

[0206] Optionally, when the first time unit includes m symbols, and the resource configuration information includes indication information corresponding to the m symbols, the processing module 1001 is configured to determine, according to the resource configuration information, a symbol corresponding to the first resource in the first time unit, including:

[0207] If the second symbol is the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the processing module 1001 is used to determine that the symbol corresponding to the first resource does not include the second symbol;

[0208] If the second symbol is not the symbol where the reference signal is located, and the indication information corresponding to the second symbol indicates that the second symbol is the symbol corresponding to the first resource, the processing module 1001 is used to determine that the symbol corresponding to the first resource includes the second symbol.

[0209] Optionally, when the first time unit includes m symbols, and the resource configuration information includes indication information corresponding to the m symbols, the processing module 1001 is configured to determine, according to the resource configuration information, a symbol corresponding to the first resource in the first time unit, including:

[0210] If the third symbol is the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the processing module 1001 is used to adjust the symbol where the reference signal is located from the third symbol to a fourth symbol, and determine that the symbol corresponding to the first resource includes the third symbol;

[0211] If the third symbol is not the symbol where the reference signal is located, and the indication information corresponding to the third symbol indicates that the third symbol is the symbol corresponding to the first resource, the processing module 1001 is used to determine that the symbol corresponding to the first resource includes the third symbol.

[0212] Optionally, when the m symbols include the fifth symbol, the processing module 1001 is further used to adjust the symbol where the reference signal is located from the fifth symbol to the sixth symbol.
