Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a resource indication method and device. Background Art

[0003] When the ambient internet of things (A-IoT) network is co-deployed with the long term evolution (LTE) network, the cell reference signal (CRS) resources of the LTE network are no longer allocated to the A-IoT network to ensure the communication performance of the LTE network.

[0004] However, when A-IoT networks are deployed together with LTE networks, how terminal devices obtain the resources of the A-IoT network is an urgent problem that needs to be solved.

[0005] Summary of the Invention

[0006] In order to solve the above technical problems, this application provides a resource indication method and apparatus, which can enable terminal devices to obtain the resources of the A-IoT network. To achieve the above purpose, this application adopts the following technical solutions:

[0007] In a first aspect, a resource indication method is provided. The method may be performed by a first apparatus, which may be a terminal device, a component applied to the terminal device (e.g., a processor, a chip, or a chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The following description uses the first apparatus as an example. The method includes: receiving first information; and determining, based on the first information, available or unavailable resources of a first network.

[0008] In other words, the first device can receive and, based on the first information, determine the available or unavailable resources of the first network. In this way, if the first network is an A-IoT network and is co-deployed with other networks, the first device can also be informed of the available or unavailable resources of the A-IoT network, thereby improving system communication performance.

[0009] In a first possible design, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, or the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network.

[0010] For example, the first network is an A-IoT network, and the second network is a Long Term Evolution (LTE) network.

[0011] For another example, the first network is an A-IoT network, and the second network is a narrowband Internet of Things NB-IoT network.

[0012] The first information indicating that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network may include: the first network and the second network are deployed in-band. In this case, the first device needs to avoid the time-frequency resources occupied by the second network.

[0013] The first information indicating that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network may include: the first network and the second network are not deployed in-band, or the second network is not deployed. In this case, the first device does not need to avoid the time-frequency resources occupied by the second network.

[0014] That is, the first information indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network, so that the first device knows whether to avoid the time-frequency resources occupied by the second network.

[0015] In a second possible design, the first information indicating that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. Alternatively, the first information indicating that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network.

[0016] The first state includes at least one of the following: the first device is in an idle state or a connected state, or the first device has been connected to the first network; and the method is applied to the first device.

[0017] That is, the first information also indicates the first state, so that the first device knows that it is in the first state to determine whether to avoid the time-frequency resources occupied by the second network.

[0018] In a third possible design, the first information indicates the number of antenna ports of the second network, where the number of antenna ports of the second network includes a first number of antenna ports, a second number of antenna ports, and a third number of antenna ports. The status value of the first information includes a first value and a second value, where the first value indicates the first number of antenna ports and / or the second number of antenna ports, and the second value indicates the third number of antenna ports. For example, the second network is an LTE network.

[0019] For the second network, different numbers of antenna ports correspond to respective resource mapping patterns. In this way, the first device can obtain the time-frequency resources occupied by the reference signal of the second network based on the number of antenna ports of the second network indicated by the first information.

[0020] In a fourth possible design, the number of the first antenna ports is 1, the number of the second antenna ports is 2, and the number of the third antenna ports is 4. For example, the second network is an LTE network.

[0021] In a fifth possible design, the resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports are the same. The resource mapping pattern corresponding to the first number of antenna ports can be understood as the resource mapping pattern occupied by the cell-specific reference signal (CRS) when the first number of antenna ports is used to send the CRS. The resource mapping pattern corresponding to the second number of antenna ports can be understood as the resource mapping pattern occupied by the CRS when the second number of antenna ports is used to send the CRS. For example, the second network is an LTE network.

[0022] In a sixth possible design, the status value of the first information further includes a third value. The first value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The second value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The third value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network, or that the second network is not deployed, or that the third value is in a reserved state. For example, the second network is an LTE network.

[0023] That is to say, in addition to indicating the number of antenna ports of the second network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network, so that the first device knows whether to avoid the time-frequency resources occupied by the reference signal of the second network.

[0024] In a seventh possible design, the antenna port is an antenna port of a cell-specific reference signal (CRS). The available resources of the first network do not include time domain symbols occupied by the CRS, or the unavailable resources of the first network include time domain symbols occupied by the CRS.

[0025] The first device does not support non-coherent demodulation, and accordingly, the first device cannot demodulate information at the resource element RE granularity. In this case, the first device can also determine the available resources or unavailable resources of the first network based on the time domain symbols occupied by the CRS.

[0026] In an eighth possible design, the first information indicates a number of symbols of a control channel of the second network, where the number of symbols includes a first number of symbols, a second number of symbols, and a third number of symbols. The state value of the first information includes a fourth value, a fifth value, and a sixth value, where the fourth value indicates the first number of symbols, the fifth value indicates the second number of symbols, and the sixth value indicates the third number of symbols. For example, the second network is an LTE network.

[0027] For the second network, the control channel of the second network may occupy a different number of symbols. In this way, the first device can obtain the time domain resources occupied by the control channel of the second network based on the number of symbols of the control channel of the second network indicated by the first information.

[0028] In a ninth possible design, the status value of the first information further includes a seventh value. The fourth value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The fifth value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The sixth value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The seventh value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network, or the second network is not deployed, or the seventh value is in a reserved state. For example, the second network is an LTE network.

[0029] That is to say, in addition to indicating the number of symbols of the control channel of the second network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network, so that the first device knows whether to avoid the time domain resources occupied by the control channel of the second network.

[0030] In a tenth possible design, the available resources of the first network do not include the time domain symbols occupied by the control channel; or, the unavailable resources of the first network include the time domain symbols occupied by the control channel.

[0031] In an eleventh possible design, the state value of the first information includes the first value, the second value, the fourth value, the fifth value, or the sixth value, and the first network and the second network are jointly deployed or coexist.

[0032] In a twelfth possible design, the time domain resources occupied by the first information are included in a first resource set, and the first resource set includes time domain symbols identified by at least one of the following indexes: 3, 5, 6, 9, 10, 12, 13.

[0033] That is, the first resource set includes available resources of the first network, and the CRS of the second network may occupy time domain symbols identified by the following indexes: 0, 4, 7, 11, or the CRS of the second network may occupy time domain symbols identified by the following indexes: 0, 1, 4, 7, 8, 11. In order to avoid the CRS of the second network, the first resource set does not include the time-frequency resources occupied by the CRS of the second network.

[0034] In a thirteenth possible design, the first resource set further includes a time domain symbol identified by a first index. The first index includes 0, 1, and 2, or the first index includes 1 and 2, or the first index includes 2.

[0035] Since the control channel of the second network occupies the time domain symbol identified by the following index: 0, or the control channel of the second network occupies the time domain symbols identified by the following indexes: 0, 1, or the control channel of the second network occupies the time domain symbols identified by the following indexes: 0, 1, 2, or the control channel of the second network occupies the time domain symbols other than those identified by the following indexes: 0, 1, 2. In order to avoid the control channel of the second network, the first resource set does not include the time domain resources occupied by the control channel of the second network.

[0036] In a fourteenth possible design, the first resource set is further used to transmit data signals of the first network and / or control signals of the first network.

[0037] In a fifteenth possible design, the first information indicates a number of antenna ports of the second network, where the number of antenna ports of the second network includes a first number of antenna ports and a second number of antenna ports. The status value of the first information includes a first value, where the first value indicates the first number of antenna ports and / or the second number of antenna ports. For example, the second network is an NB-IoT network.

[0038] For the second network, different numbers of antenna ports correspond to respective resource mapping patterns. In this way, the first device can obtain the time-frequency resources occupied by the reference signal of the second network based on the number of antenna ports of the second network indicated by the first information.

[0039] In a sixteenth possible design, the number of the first antenna ports is 1, and the number of the second antenna ports is 2.

[0040] In a seventeenth possible design, the resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports are the same. The resource mapping pattern corresponding to the first number of antenna ports can be understood as the resource mapping pattern occupied by the NRS when the NRS is sent using the first number of antenna ports. The resource mapping pattern corresponding to the second number of antenna ports can be understood as the resource mapping pattern occupied by the NRS when the NRS is sent using the second number of antenna ports.

[0041] In an eighteenth possible design, the status value of the first information further includes a second value. The first value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. The second value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network, or the second network is not deployed, or the second value is in a reserved state. For example, the second network is an NB-IoT network.

[0042] That is to say, in addition to indicating the number of antenna ports of the second network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network, so that the first device knows whether to avoid the time-frequency resources occupied by the reference signal of the second network.

[0043] In a nineteenth possible design, the antenna port of the second network is an antenna port of a narrowband reference signal (NRS). The available resources of the first network do not include time-domain symbols occupied by the NRS, or the unavailable resources of the first network include time-domain symbols occupied by the NRS. For example, the second network is an NB-IoT network.

[0044] The first device does not support non-coherent demodulation, and accordingly, the first device cannot demodulate information at the resource element RE granularity. In this case, the first device can also determine the available resources or unavailable resources of the first network based on the time domain symbols occupied by the NRS.

[0045] In a twentieth possible design, the time domain resources occupied by the first information are included in a third resource set, and the third resource set includes time domain symbols identified by at least one of the following indexes: 0, 1, 2, 3, 4, 7, 8, 9, 10, 11.

[0046] That is, the third resource set includes available resources of the first network, and the NRS of the second network may occupy time domain symbols identified by the following indexes: 5, 6, 12, 13. To avoid the NRS of the second network, the third resource set does not include time domain resources occupied by the NRS of the second network.

[0047] In a twenty-first possible design, the third resource set is also used to transmit data signals of the first network and / or control signals of the first network.

[0048] In the first aspect, the first possible design to the second possible design of the first aspect are applicable when the second network is an LTE network or an NB-IoT network. The third possible design to the fourteenth possible design of the first aspect are applicable when the second network is an LTE network. The fifteenth possible design to the twenty-first possible design of the first aspect are applicable when the second network is an NB-IoT network.

[0049] In a second aspect, a resource indication method is provided. The method may be performed by a first apparatus, which may be a terminal device, a component applied to the terminal device (e.g., a processor, a chip, or a chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The following description uses the first apparatus as an example. The method includes: receiving first information; and determining, based on the first information, available or unavailable resources of a first network.

[0050] In other words, the first device can receive and, based on the first information, determine the available or unavailable resources of the first network. In this way, if the first network is an A-IoT network and is co-deployed with other networks, the first device can also be informed of the available or unavailable resources of the A-IoT network, thereby improving system communication performance.

[0051] In a first possible design, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network. The first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network. The first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network. Alternatively, the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and outside the time-frequency resources of the third network.

[0052] For example, the first network is an Ambient Internet of Things (A-IoT) network, the second network is a Long Term Evolution (LTE) network, and the third network is a Narrowband Internet of Things (NB-IoT) network.

[0053] For another example, the first network is an A-IoT network, the second network is an NB-IoT network, and the third network is an LTE network.

[0054] That is, the first information indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network and the third network, so that the first device knows whether to avoid the time-frequency resources occupied by the second network and the third network.

The first information indicating that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network. The first information indicating that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network. The first information indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network, including: the first information indicates that in the first state, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network.

[0056] The first state includes at least one of the following: the first device is in an idle state or a connected state, or the first device has been connected to the first network; and the method is applied to the first device.

[0057] That is, the first information also indicates the first state, so that the first device knows that whether to avoid the time-frequency resources occupied by the second network and the third network is determined only in the first state.

[0058] In a third possible design, the first information indicates the number of antenna ports of the second network, where the number of antenna ports of the second network includes a first number of antenna ports, a second number of antenna ports, and a third number of antenna ports. The state value of the first information includes a first value, a second value, a third value, and a fourth value.

The third value indicates the third number of antenna ports, and the fourth value indicates the third number of antenna ports. For example, the second network is an LTE network.

[0059] For the second network, different numbers of antenna ports correspond to respective resource mapping patterns. In this way, the first device can obtain the time-frequency resources occupied by the reference signal of the second network based on the number of antenna ports of the second network indicated by the first information.

[0060] In a fourth possible design, the first value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network. The second value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, or indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and the third network is not deployed. The third value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network. The fourth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, or indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and the third network is not deployed. For example, the second network is an LTE network.

[0061] That is, in addition to indicating the number of antenna ports of the second network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network and the third network, so that the first device knows: in addition to avoiding the time-frequency resources occupied by the reference signal of the second network, whether to avoid the time-frequency resources occupied by the third network.

[0062] In a fifth possible design, the number of the first antenna ports is 1, the number of the second antenna ports is 2, and the number of the third antenna ports is 4.

[0063] In a sixth possible design, the resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports are the same. The resource mapping pattern corresponding to the first number of antenna ports can be understood as the resource mapping pattern occupied by the cell-specific reference signal (CRS) when the first number of antenna ports is used to send the CRS. The resource mapping pattern corresponding to the second number of antenna ports can be understood as the resource mapping pattern occupied by the CRS when the second number of antenna ports is used to send the CRS.

[0064] In a seventh possible design, the antenna port of the second network is an antenna port of a cell-specific reference signal (CRS). The available resources of the first network do not include time domain symbols occupied by the CRS, or the unavailable resources of the first network include time domain symbols occupied by the CRS.

[0065] The first device does not support non-coherent demodulation, and accordingly, the first device cannot demodulate information at the resource element RE granularity. In this case, the first device can also determine the available resources or unavailable resources of the first network based on the time domain symbols occupied by the CRS.

[0066] In an eighth possible design, the first information indicates a number of antenna ports of the third network, where the number of antenna ports of the third network includes a fourth number of antenna ports and a fifth number of antenna ports. The status value of the first information includes a fifth value, where the fifth value indicates the fourth number of antenna ports and / or the fifth number of antenna ports. For example, the third network is an NB-IoT network.

[0067] For the third network, different numbers of antenna ports correspond to respective resource mapping patterns. In this way, the first device can obtain the time-frequency resources occupied by the reference signal of the third network based on the number of antenna ports of the third network indicated by the first information.

[0068] In a ninth possible design, the number of the fourth antenna ports is 1, and the number of the fifth antenna ports is 2.

[0069] In a tenth possible design, the resource mapping pattern corresponding to the fourth number of antenna ports is the same as the resource mapping pattern corresponding to the fifth number of antenna ports.

The resource mapping pattern corresponding to the fifth number of antenna ports can be understood as the resource mapping pattern occupied by the NRS when the fifth number of antenna ports is used to send the NRS.

[0070] In an eleventh possible design, the status value of the first information also includes a sixth value. The fifth value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and within the time-frequency resources of the third network, or indicates that the second network is not deployed and the time-frequency resources occupied by the first network are within the time-frequency resources of the third network. The sixth value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network, or indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and the third network is not deployed, or indicates that the second network is not deployed and the time-frequency resources occupied by the first network are outside the time-frequency resources of the third network, or indicates that the second network is not deployed and the third network is not deployed. For example, the third network is an NB-IoT network.

[0071] That is, in addition to indicating the number of antenna ports of the third network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network and the third network, so that the first device knows: in addition to not avoiding the time-frequency resources occupied by the second network, whether to avoid the time-frequency resources occupied by the reference signal of the third network.

[0072] In a twelfth possible design, the antenna port of the third network is an antenna port of a narrowband reference signal (NRS). The available resources of the first network do not include time-domain symbols occupied by the NRS, or the unavailable resources of the first network include time-domain symbols occupied by the NRS. For example, the third network is an NB-IoT network.

[0073] The first device does not support non-coherent demodulation, and accordingly, the first device cannot demodulate information at the resource element RE granularity. In this case, the first device can also determine the available resources or unavailable resources of the first network based on the time domain symbols occupied by the NRS.

For example, the second network is an LTE network.

[0075] For the second network, the control channel of the second network may occupy a different number of symbols. In this way, the first device can obtain the time domain resources occupied by the control channel of the second network based on the number of symbols of the control channel of the second network.

[0076] In a fourteenth possible design, the status value of the first information further includes a tenth value.

For example, the second network is an LTE network.

[0077] That is to say, in addition to indicating the number of symbols of the control channel of the second network, the first information also indicates the positional relationship between the time-frequency resources of the first network and the time-frequency resources of the second network, so that the first device knows whether to avoid the time-frequency resources occupied by the control channel of the second network.

[0078] In a fifteenth possible design, the available resources of the first network do not include the time domain symbols occupied by the control channel; or, the unavailable resources of the first network include the time domain symbols occupied by the control channel.

For example, the second network is an LTE network.

[0080] In a seventeenth possible design, the time domain resources occupied by the first information are included in a second resource set, and the second resource set includes time domain symbols identified by at least one of the following indexes: 3, 9, 10.

[0081] That is, the second resource set includes available resources of the first network. The CRS of the second network may occupy time domain symbols identified by the following indices: 0, 4, 7, 11, or the CRS of the second network may occupy time domain symbols identified by the following indices: 0, 1, 4, 7, 8, 11. The NRS of the third network may occupy time domain symbols identified by the following indices: 5, 6, 12, 13. To avoid the CRS of the second network and the NRS of the third network, the second resource set does not include the time domain resources occupied by the CRS of the second network and the NRS of the third network.

[0082] In an eighteenth possible design, the second resource set also includes a time domain symbol identified by a second index; the second index includes 0, 1, 2, or the second index includes 1, 2, or the second index includes 2.

[0083] Since the control channel of the second network occupies the time domain symbol identified by the following index: 0, or the control channel of the second network occupies the time domain symbols identified by the following indexes: 0, 1, or the control channel of the second network occupies the time domain symbols identified by the following indexes: 0, 1, 2, or the control channel of the second network occupies the time domain symbols other than those identified by the following indexes: 0, 1, 2. In order to avoid the control channel of the second network, the second resource set does not include the time domain resources occupied by the control channel of the second network.

[0084] In a nineteenth possible design, the second resource set is further used to transmit data signals of the first network and / or control signals of the first network.

[0085] In the second aspect, the first possible design to the second possible design of the second aspect are applicable when the second network is an LTE network and the third network is an NB-IoT network, or when the second network is an NB-IoT network and the third network is an LTE network. The third possible design to the nineteenth possible design of the second aspect are applicable when the second network is an LTE network and the third network is an NB-IoT network.

[0086] In combination with the first aspect or the second aspect, in a possible design, the first information is carried on a broadcast channel. That is, the first information is received via the broadcast channel.

[0087] In combination with the first aspect or the second aspect, in one possible design, the method is applied to a first device, where the first device is served by the first network.

[0088] In combination with the first aspect or the second aspect, in one possible design, the method is applied to a first device, which satisfies at least one of the following: supports non-coherent demodulation; supports envelope detection; supports amplitude modulation ASK; supports frequency modulation FSK; supports non-orthogonal frequency division multiplexing OFDM receiver structure; does not support OFDM reception and demodulation; or does not support in-phase orthogonal IQ demodulation.

[0089] That is, the first device cannot demodulate information at RE granularity.

The second information indicates a first resource and / or a second resource, wherein the first resource is continuous in the frequency domain and is used for the first apparatus to access the first network, and the second resource is continuous in the frequency domain and is used for synchronization between the first apparatus and the first network.

[0091] That is to say, if the second information indicates the first resource, it means that the first device is allocated the first resource that is continuous in the frequency domain, so that the access process is performed on the first resource, which helps to reduce the probability of the access process being interrupted and reduce the access delay.

[0092] If the second information indicates the second resource, it means that the first device is allocated the second resource that is continuous in the frequency domain, so that it receives the synchronization signal on the second resource and completes synchronization with the first network, which helps to reduce the probability of the synchronization process being interrupted and reduce the synchronization delay.

[0093] In combination with the first or second aspect, in one possible design, the first resource is continuous in the time domain. Because the first resource is continuous in the time domain, the impact of other networks on information transmission on the first resource can be avoided, which helps to further reduce the probability of the access process being interrupted and reduce access latency.

Any embodiment or design described in this application as an "example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of the word "example" is intended to present concepts in a concrete manner.

[0203] In the embodiments of the present application, “of”, “corresponding”, “relevant” and “corresponding” may sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0204] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0205] Figure 1a is a schematic diagram of the architecture of a communication system used in an embodiment of the present application. As shown in Figure 1a, the communication system includes a first device and a second device. The first device and the second device can communicate with each other. For example, the first device can be the terminal device of Figure 1b, and the second device can be the network device of Figure 1b. Alternatively, the first device can be the network device of Figure 1b, and the second device can be the terminal device of Figure 1b.

[0206] Figure 1b is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1b, the communication system 1000 includes at least one network device (such as 110a and 110b in Figure 1b) and at least one terminal device (such as 120a-120j in Figure 1b). The terminal device can communicate with the network device wirelessly. Optionally, different network devices can communicate with each other. Optionally, different terminal devices can communicate with each other.

[0207] It should be noted that Figure 1b is only a schematic diagram. Although not shown, the communication system 1000 can also include other network devices. For example, the communication system 1000 can also include one or more core network (CN) devices, wireless relay devices and wireless backhaul devices, which are not specifically limited here.

[0208] The network device can be connected to the core network device via wireless or wired communication. The core network device and the network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the network device can be integrated into the same physical device, or the functions of some core network devices and some network devices can be integrated into one physical device. This embodiment of the present application does not specifically limit this.

[0209] Optionally, the network device is a network-side device with wireless transceiver functions. The network device may be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, referred to as a RAN device. The RAN may be an access network in the 3rd Generation Partnership Project (3GPP), for example, 4G, 5G, or the future-oriented 6G network. The RAN may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. The RAN device may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation base station (next generation nodeB, gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, a wireless fidelity (WiFi) system, a long-range radio (LoRa) system, or an access node in a vehicle networking system. RAN equipment can also be a module or unit that performs some of the functions of a base station. For example, it can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU here performs the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), and can also perform the functions of the service data adaptation protocol (SDAP); the DU performs the functions of the base station's radio link control layer and medium access control (MAC) layer, and can also perform some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be set up separately, or they can be included in the same network element, such as the baseband unit (BBU).The RU may be included in a radio frequency device or radio frequency unit, for example, a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). In different systems, CU, DU, or RU may have different names, but those skilled in the art will understand their meanings. For example, in an ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, and RU may also be called O-RU. Any of the CU (or CU-CP, CU-UP), DU, and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The radio access network device may be a macro base station (such as 110a in Figure 1b), a micro base station or an indoor station (such as 110b in Figure 1b), a relay node, a donor node, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the radio access network device. For ease of description, network device is referred to as the abbreviation of radio access network device, and base station is used as an example of radio access network device.

[0210] Optionally, the terminal device accesses the core network via a network device. The terminal device includes a device that provides voice and / or data connectivity to the user. Specifically, it includes a device that provides voice to the user, a device that provides data connectivity to the user, or a device that provides both voice and data connectivity to the user. For example, it may include a handheld device with wireless connectivity or a processing device connected to a wireless modem. The terminal device can communicate with the core network via the radio access network, exchange voice or data with the RAN, or exchange voice and data with the RAN. The terminal device may include user equipment (UE), wireless terminal device, mobile terminal device, D2D terminal device, V2X terminal device, machine-to-machine / machine-type communications (M2M / MTC) terminal device, Internet of Things (IoT) terminal device, subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user device, etc. For example, it may include a mobile phone (or so-called "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). Also included are limited devices, such as those with low power consumption, limited storage capacity, or limited computing power. Examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners.

[0211] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBUs).

[0212] In the embodiment of the present application, the terminal device may further include a relay. Alternatively, it can be understood that anything that can communicate data with a base station can be considered a terminal device.

[0213] In the embodiments of the present application, the device for implementing the functions of the terminal device can be the terminal device, or it can be a device that can support the terminal device to implement the functions, such as a chip system, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices. In the technical solutions provided in the embodiments of the present application, the device for implementing the functions of the terminal is a terminal device as an example for description.

[0214] It should be understood that network devices and terminal devices can be fixed or mobile. Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on aircraft, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0215] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1b can be configured as a mobile base station. To terminal devices 120j that access the wireless access network through 120i, terminal device 120i is a network device; but to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a network device. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1b can be referred to as communication devices with network device functionality, and 120a-120j in Figure 1b can be referred to as communication devices with terminal device functionality.

[0216] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through authorized spectrum, unauthorized spectrum, or both. They can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communications.

[0217] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device functions. The control subsystem that includes the network device functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device functions.

[0218] In an embodiment of the present application, a network device sends a downlink signal or downlink information to a terminal device, and the downlink information is carried on a downlink channel; the terminal device sends an uplink signal or uplink information to the network device, and the uplink information is carried on an uplink channel. In order to communicate with the network device, the terminal device needs to establish a wireless connection with the cell controlled by the network device. The cell with which the terminal device has established a wireless connection is called the serving cell of the terminal device. When the terminal device communicates with the serving cell, it will also be interfered with by signals from neighboring cells.

[0219] It should be noted that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0220] To facilitate understanding of the embodiments of the present application, the following briefly describes the terms used in the embodiments of the present application. It should be understood that these descriptions are only for facilitating understanding of the embodiments of the present application and should not constitute any limitation on the present application.

[0221] 1. Internet of Things (IoT)

[0222] IoT stands for the Internet of Things. It extends the internet's user end to any object, enabling information exchange and communication between any object. This type of communication is also known as machine-type communications (MTC).

[0223] An increasing number of IoT devices are already being deployed in our daily lives. Examples include smart water meters, shared bicycles, and devices focused on sensing and data collection for smart cities, environmental monitoring, smart homes, and forest fire prevention. In the future, IoT devices will be ubiquitous, embedded in every piece of clothing, package, and key. Virtually all offline items will be brought online through IoT technology.

[0224] However, due to the widespread distribution and large number of IoT devices, achieving the Internet of Everything presents significant challenges to the industry, with power supply being the primary challenge. Currently, IoT technology is still primarily driven by carriers, and IoT modules (the models within IoT devices) communicate with network devices (such as base stations) using standard cellular protocols. Because network devices (such as base stations) need to cover as large an area as possible, IoT modules must be able to communicate even at great distances from them. This requires IoT modules to consume up to 30mA of current during wireless communication, necessitating the use of relatively high-capacity batteries. This also makes it difficult to reduce the size of IoT modules, increasing the cost of IoT devices.

[0225] Furthermore, some low-power end devices play a vital role in IoT applications such as healthcare, smart homes, industrial sensors, and wearables. However, due to the limited size of these devices, extending their operating time is difficult to achieve simply by increasing battery capacity. Therefore, reducing the power consumption of wireless communications is crucial to extending end-device battery life. Among these components, the radio transceiver is one of the most power-hungry.

[0226] Therefore, in order to further popularize IoT technology and implant IoT modules into the human body or smaller objects, it is no longer possible to use higher-capacity batteries. Instead, it is necessary to use smaller batteries or even completely get rid of battery limitations, or design a method to reduce the power consumption of radio transceivers to solve the cost, size, power consumption and other limitations of IoT devices.

[0227] 2. Low-power ambient IoT (A-IoT)

[0228] During the 3GPP Release-18 standardization discussions, a study on low-power wake-up signals and receivers for new radio (NR) was approved. Furthermore, A-IoT was also discussed at the 3GPP plenary meeting.

[0229] A-IoT is a type of ultra-low power IoT device, which is mainly divided into active and passive types.

[0230] Active A-IoT is an active tag or active terminal that uses the energy stored in its own energy storage module to transmit wireless signals. Active A-IoT can also be described by other terms, such as active A-IoT device, active A-IoT terminal, active A-IoT terminal device, active IoT, active IoT device, active IoT terminal, active IoT terminal device, active tag, active terminal, active terminal device, etc. These terms are collectively described here and will not be further elaborated.

[0231] For example, Figure 2 shows a schematic diagram of an active A-IoT network architecture. In Figure 2, active A-IoT devices can communicate directly with network devices.

[0232] Among them, passive A-IoT mainly relies on obtaining energy from external RF signals and communicating by backscattering RF signals, ultimately achieving ultra-low power consumption or even zero power consumption. In addition, passive A-IoT can also be described in other ways, such as passive A-IoT device, passive A-IoT terminal, passive A-IoT terminal device, passive IoT device, passive IoT terminal, passive IoT terminal device, passive source tag (passive tag), battery-free terminal, battery-free device, battery-free terminal, battery-free device, backscatter terminal, backscatter device, etc., which are all described here as a unified description and will not be repeated in the following text.

[0233] For example, Figure 3 is a schematic diagram of a passive A-IoT network architecture. In Figure 3, the link between the terminal device (such as a mobile phone) and the passive A-IoT device is a passive link. A passive A-IoT device (such as a passive tag) cannot actively send radio frequency signals by itself. The terminal device (such as a mobile phone) needs to first transmit a carrier signal (or excitation signal). Correspondingly, the passive A-IoT device (such as a passive tag) receives the carrier signal (or excitation signal), modulates the carrier signal, and then sends the modulated signal to the terminal device (such as a mobile phone) or the network device (such as a base station). Among them, the carrier signal carries downlink data (DL data), and the modulated signal carries uplink data (UL data).

[0234] 3. A-IoT Receiver

[0235] In this application, an A-IoT receiver can be a receiver for an A-IoT device. Considering its low power consumption, the A-IoT receiver does not include a high-power, high-precision phase-locked loop (PLL) module. The A-IoT receiver does not support coherent demodulation, but does support low-power envelope detection.

[0236] For example, the A-IoT receiver can receive an on-off keying (OOK) modulated signal or an amplitude-shift keying (ASK) modulated signal.

[0237] For another example, an A-IoT receiver can receive signals that do not require a fast Fourier transform (FFT) or an inverse fast Fourier transform (IFFT) during the generation or decoding process.

[0238] For example, an A-IoT receiver can receive Manchester-encoded signals.

[0239] In this application, the receiver in a passive A-IoT device can be described as: a passive A-IoT receiver, a backscatter receiver, a zero-power receiver, an extremely low-power receiver, a receiver that absorbs RF signals, a receiver that reflects RF signals, etc.

[0240] In addition, the passive A-IoT receiver itself cannot actively send RF signals. Please refer to the introduction in Figure 3 and will not be repeated here.

[0241] When using OOK modulation, each bit (which may be an encoded bit) corresponds to a symbol. A symbol is also called a chip. When a bit is 1, a signal is transmitted within the symbol length (i.e., the signal power is non-zero within the symbol length). Conversely, when a bit is 0, no signal is transmitted within the symbol length (i.e., the signal power is zero within the symbol length).

[0242] It should be understood that, as a possible alternative, when a bit is 0, a signal is transmitted within the symbol length (i.e., the signal power within the symbol length is not 0). Conversely, when a bit is 1, no signal is transmitted within the symbol length (i.e., the signal power within the symbol length is 0), which is not limited in this application.

[0243] It should be noted that in this application, A-IoT receivers are different from traditional high-energy receivers. Traditional high-energy receivers are receivers that can receive synchronization signal blocks (SSBs), physical downlink control channels (PDCCHs), physical downlink shared channels (PDSCHs), or channel state information reference signals (CSI-RSs).

[0244] For example, a conventional high-power receiver can receive binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64QAM, or 256QAM modulated signals.

[0245] For another example, a conventional high-energy consumption receiver may receive a signal that has undergone an FFT or IFFT during the generation or decoding process.

[0246] For another example, a traditional high-energy consumption receiver is a receiver with a relatively high local oscillator accuracy.

[0247] 4-1, ASK

[0248] ASK modulation adjusts the carrier amplitude based on the value of the digital signal, while maintaining the carrier frequency and phase. As shown in Figure 4, the transmitted digital signal is a binary signal consisting of 0s and 1s. Compared to the carrier signal, the modulated signal transmits one amplitude signal when a bit is 1 (maintaining the carrier amplitude unchanged) and another amplitude signal when a bit is 0 (the amplitude becomes 0). Clearly, ASK modulation modulates one bit of data into one symbol. The modulated signal has two symbol waveforms, one for transmitting 1s and one for transmitting 0s. 2ASK is also known as OOK.

[0249] In the ASK modulation method, the carrier signal can be expressed as: f(t) = Asin(2πft+θ) Formula (1)

[0250] Wherein, f(t) represents the carrier signal, A represents the amplitude of the carrier signal, f represents the frequency of the carrier signal, and θ represents the initial phase of the carrier signal.

[0251] 4-2, OOK

[0252] OOK demodulation primarily utilizes non-coherent demodulation. This includes envelope detection, which typically uses a diode for unidirectional filtering followed by low-pass filtering. The signal undergoes a bandpass filter, envelope detector, and sampling decision to achieve OOK signal demodulation, as shown in Figure 5.

[0253] For low-power non-coherent receivers, it is difficult to demodulate information at the resource element (RE) granularity. Generally, the bandpass filter width is on the order of resource blocks (RBs). The information carried by the signal is obtained by measuring the signal envelope characteristics within this bandpass filter bandwidth (on the order of RBs).

[0254] 5. Narrowband Internet of Things (NB-IoT) deployment model

[0255] NB-IoT occupies 180kHz bandwidth in the frequency domain, corresponding to one RB in LTE transmission. The subcarrier spacing is 3.75kHz or 15kHz. For example, when NB-IoT and LTE networks coexist, three deployment methods are supported:

[0256] The first deployment method, standalone deployment, uses a separate frequency band for NB-IoT, such as one or more carriers, to transmit NB-IoT-related information, as shown in Figure 6. This method is primarily applicable to refarming the Global System for Mobile Communications (GSM) frequency band. Since a single GSM carrier has a bandwidth of 200 kHz, NB-IoT can be deployed on the GSM band with 10 kHz of guard bands reserved at each end.

[0257] The second deployment method, guardband deployment, utilizes unused RB resources in the guard band of the LTE carrier to deploy NB-IoT, as shown in Figure 7. The LTE channel bandwidth includes the LTE guard band and the LTE transmission bandwidth.

[0258] The third deployment method is in-band deployment: NB-IoT is deployed using RBs on the transmission bandwidth of the LTE carrier (i.e., the LTE transmission bandwidth), as shown in Figure 8.

[0259] The network device uses the narrowband master system information block (MasterInformationBlock-NB) operating mode information element (operationModeInfo-r13) to indicate the current deployment mode of the NB-IoT cell. In other words, the terminal device needs to receive MIB-NB to know the deployment mode used by the cell.

[0260] However, in in-band deployment, unavailable resources for NB-IoT include:

[0261] The first item is the resources for the cell-specific reference signal (CRS) of the LTE network.

[0262] The second item is the resources occupied by CSI-RS, where CSI-RS is a reference signal that may exist in the LTE network.

[0263] The third item is the resources of the control area for the LTE downlink control channel. The downlink control channel may include a layer 1 (layer 1, L1) control channel or a layer 2 (layer 2, L2) control channel. The downlink control channel may include one or more of the following: a physical control format indicator channel (PCFICH), a physical hybrid-ARQ indicator channel (PHICH), and a physical downlink control channel (PDCCH). The resources of the control area may include one or more REs, or the resources of the control area may include one or more orthogonal frequency division multiplexing (OFDM) symbols. In addition, OFDM symbols can also be referred to as symbols for short. The two have the same meaning and can be replaced with each other.

[0264] The above three resources occupy the entire LTE system bandwidth. When deploying NB-IoT, these resources must be avoided to ensure the original LTE signal transmission.

[0265] In addition, the signal that occupies the entire system bandwidth can be described as an always-on signal.

[0266] However, in other deployment modes, such as guard band deployment and independent deployment, the above problems do not exist.

[0267] 6. A-IoT deployment model

[0268] Currently, when A-IoT coexists with LTE networks, three deployment modes are supported: independent deployment, guard band deployment, and in-band deployment. Please refer to the introduction of NB-IoT deployment mode for details.

[0269] 7. 5G NR SSB

[0270] The SSB in NR mainly includes the following four items:

[0271] The first item is the primary synchronization signal (PSS), which is the signal that the terminal device searches for when it powers on and enters the NR system. During this phase, the terminal device searches for cells on a given carrier frequency. If the terminal device detects the PSS, it determines the PSS period based on the PSS, meaning that the terminal device synchronizes to the PSS period.

[0272] The second item is the secondary synchronization signal (SSS). That is, if the terminal device detects the PSS, the transmission timing of the SSS is determined according to the PSS. The terminal device determines the physical cell identifier (PCI) by detecting the SSS.

[0273] The third item is the physical broadcast channel (PBCH). The PBCH primarily carries information called the master information block (MIB). The MIB includes information such as the system frame number, cell block indicator, and the system information block (SIB) parameter set. Terminal devices use the MIB to obtain the remaining system information broadcast by the network.

[0274] The fourth item is the demodulation reference signal for PBCH (DMRS for PBCH). Since there is no CRS in the NR system, the terminal device first obtains the DMRS for PBCH when demodulating the PBCH.

[0275] Each beam is configured with the PSS, SSS, PBCH, and DMRS (DMRS for PBCH) to enable downlink synchronization of terminal devices. The PSS, SSS, PBCH, and DMRS (DMRS for PBCH) are transmitted simultaneously. The NR system bundles the PSS, SSS, PBCH, and DMRS (DMRS for PBCH) to ensure simultaneous transmission. These are collectively referred to as SSBs (SSBs can also be referred to as SS / PBCH blocks). A beam carrying an SSB is described as an SSB beam.

[0276] In addition, during the movement, the terminal device continuously searches and measures cells based on SSB, selects the appropriate SSB beam, and realizes initial access and mobility management.

[0277] In the NR system, more antennas are used for enhanced coverage. However, more antennas result in narrower beams radiated by the antennas. A single narrow beam cannot cover the entire cell. Therefore, the NR system covers the entire cell through beam scanning. That is, at a certain moment, the network device can send a beam in one beam direction, and at another moment, the network device sends a beam in another beam direction. By sending different beams at multiple times, the entire cell is covered.

[0278] In the NR system, the SSB period is 20ms, occupying 20 RBs and not taking up the entire system bandwidth. Furthermore, the SSB time and frequency position is relatively flexible. When deployed with other networks, the network equipment side effectively avoids NR's SSB. The specific details are not elaborated here.

[0279] 8. CRS in LTE networks

[0280] In LTE networks, CRSs occupy the entire LTE system bandwidth in the frequency domain. Specifically, CRSs are transmitted in every downlink subframe, in every RB within the entire downlink system bandwidth. A cell can use one CRS, corresponding to one antenna port, as shown in Figure 9. A cell can use two CRSs, corresponding to two antenna ports, as shown in Figure 10. A cell can use four CRSs, corresponding to four antenna ports, as shown in Figure 11. In other words, the CRS mapping method differs for different numbers of antenna ports.

[0281] In Figures 9-11, on each antenna port, the REs occupied by CRS are no longer used for other transmissions. Furthermore, if a certain RE on a particular antenna port is used to transmit CRS, the REs at the same time-frequency location on other antenna ports are no longer used for other transmissions, thereby preventing CRS from being interfered with by transmissions on other antenna ports.

[0282] By receiving the MIB, the terminal device learns the number of antenna ports specific to the cell (such as 1, 2 or 4), thereby determining how many CRSs are used in the same cell, that is, on which antenna ports the CRSs are transmitted.

[0283] In addition, in the LTE network, the PDCCH occupies the entire LTE system bandwidth in the frequency domain and occupies the first three symbols of a subframe in the time domain.

[0284] 9. NB-IoT narrowband reference signal (NRS)

[0285] The NRS is primarily used for downlink physical channel channel estimation and downlink channel quality measurement, such as measuring reference signal received power (RSRP) and reference signal received quality (RSRQ). In an NB-IoT network, each downlink antenna port (also known as a downlink NB-IoT antenna port) corresponds to an NRS. When the number of downlink antenna ports is 1, the NRS resource mapping pattern is shown in Figure 12; when the number of downlink antenna ports is 2, the NRS resource mapping pattern is shown in Figure 13. In other words, the NRS mapping method varies for different numbers of antenna ports.

[0286] In addition, the generation method of NRS is the same as that of CRS in LTE, occupying the entire system bandwidth of the NB-IoT network and belonging to the always-on signal in NB-IoT.

[0287] 10. NB-IoT and LTE networks are deployed together

[0288] After the terminal device determines the cell to be communicated, it needs to obtain the system information of the cell (such as MIB-NB, SIB-NB). The following introduces the resource mapping solution when the LTE network and NB-IoT are deployed together:

[0289] In the first solution, in in-band mode, the network device indicates the following information to the terminal device:

[0290] Information A, the deployment mode of the NB-IoT and LTE networks, such as whether it is in-band, guardband, or standalone. Information A is indicated by two bits in MIB-NB.

[0291] In-band deployments include two scenarios: SamePCI and DiffPCI. SamePCI indicates that the NB-IoT cell and the LTE cell use the same cell identifier, such as PCI. DiffPCI indicates that the NB-IoT cell and the LTE cell use different cell identifiers.

[0292] Information B, the number of antenna ports and raster offset of NB-IoT. Among them, the raster offset is used to indicate the position of the NB-IoT carrier within the LTE system bandwidth, such as the distance of the NB-IoT carrier relative to the center of the LTE carrier and the offset between the NB-IoT center frequency and the nearest integer multiple of 100kHz. Exemplarily, there are 4 types of raster offset, such as ±7.5kHz, ±2.5kHz, etc. Information B is indicated by the eutra-CRSSequenceInfo-r13 field in MIB-NB, such as occupying 5 bits in the eutra-CRSSequenceInfo-r13 field.

[0293] It is easy to understand that when information A indicates that the deployment mode is In-band deployment, if the NB-IoT cell and the LTE cell use different cell identifiers (i.e., diffPCI), the MIB does not include information B; if the NB-IoT cell and the LTE cell use the same cell identifier (i.e., SamePCI), the MIB includes information B. In this case, the network device indicates the resource mapping mode under common deployment through 7 bits.

[0294] In the case where information A indicates that the deployment mode is guardband deployment or standalone deployment, the MIB does not include information B.

[0295] In the second solution, under guardband deployment, the network device does not need to indicate the raster offset to the terminal device.

[0296] In the third solution, in a standalone deployment, the center frequency of the NB-IoT anchor carrier deviates by no more than 7.5 kHz from the nearest 100 kHz grid, allowing the terminal device to synchronize with the network.

[0297] In summary, when NB-IoT and LTE networks are deployed together, a total of 7 bits in MIB-NB are required for indication.

[0298] 11. A-IoT is deployed together with other networks

[0299] When A-IoT is deployed alongside other networks (such as LTE and NB-IoT), signals from these other networks may occupy the entire system bandwidth, preventing it from being allocated to A-IoT. However, terminal devices cannot be informed of the available or unavailable resources of A-IoT, impacting communication performance.

[0300] In view of this, an embodiment of the present application provides a resource indication method, which can be applied to the communication system shown in Figure 1a. In the resource indication method provided in the embodiment of the present application, a first device receives first information and determines available resources or unavailable resources of a first network based on the first information.

[0301] In other words, the first device can determine the available or unavailable resources of the first network based on the first information. This allows the first device to know the available or unavailable resources of the A-IoT network, even if the first network is an A-IoT network and is co-deployed with other networks, thereby improving system communication performance.

[0302] It should be understood that the message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in specific implementations. The embodiments of the present application do not specifically limit this.

[0303] 14 and 15, the resource indication method proposed in the embodiment of the present application is described in detail. The resource indication method 1400 proposed in the embodiment of the present application includes the following operations:

[0304] S1401. The first device receives first information.

[0305] Exemplarily, the first device is described as follows:

[0306] The first device may be a terminal device, as described in FIG1a or FIG1b , which will not be described in detail.

[0307] The first device is provided with services by the first network. For example, the first device sends or receives service data via the first network. In an embodiment of the present application, the first network may be an A-IoT network.

[0308] The first device satisfies at least one of the following:

[0309] The first one supports non-coherent demodulation.

[0310] The second item supports envelope detection.

[0311] The third item is support for ASK.

[0312] The fourth item is to support FSK.

[0313] Fifth, support for non-OFDM receiver structures.

[0314] Sixth, OFDM reception and demodulation are not supported.

[0315] Seventh, in-phase quadrature (IQ) demodulation is not supported.

[0316] For example, the first device includes an A-IoT receiver. For details, please refer to the introduction of the A-IoT receiver and will not be repeated here.

[0317] For example, the implementation process of S1401 is introduced with reference to three examples (Example 1 to Example 3 below):

[0318] Example 1, S1401 includes S1401a: the first device receives first information from the first network.

[0319] For example, the second device on the first network sends first information to the first device, and correspondingly, the first device receives the first information from the second device on the first network.

[0320] Exemplarily, the second device may be a network device, as described in FIG. 1a or FIG. 1b , which will not be described in detail.

[0321] It should be understood that the applicable scenarios of Example 1 are as follows:

[0322] In the first scenario, the first network is deployed, but the second and third networks are not deployed.

[0323] In the second scenario, the first network and the second network are deployed, but the third network is not deployed.

[0324] The third scenario deploys the first network, the second network, and the third network.

[0325] In the three scenarios above, the first network can be an A-IoT network, the second network can be an LTE network, and the third network can be an NB-IoT network. Alternatively, the first network can be an A-IoT network, the second network can be an NB-IoT network, and the third network can be an LTE network.

[0326] Example 2, S1401 includes S1401b: the first device receives first information from the second network.

[0327] For example, a third device on the second network sends first information to a first device, and correspondingly, the first device receives the first information from the third device on the second network.

[0328] Exemplarily, the third device is similar to the second device and may be a network device, as described in FIG. 1a or FIG. 1b , which will not be described in detail.

[0329] It should be understood that the applicable scenarios of Example 2 are as follows:

[0330] In the first scenario, the first network and the second network are deployed, but the third network is not deployed.

[0331] In the second scenario, the first network, the second network, and the third network are deployed.

[0332] In the above two scenarios, the first network can be an A-IoT network, the second network can be an LTE network, and the third network can be an NB-IoT network. Alternatively, the first network can be an A-IoT network, the second network can be an NB-IoT network, and the third network can be an LTE network.

[0333] Example 3, S1401 includes S1401c: the first device receives first information from the third network.

[0334] For example, the fourth device on the third network sends the first information to the first device. Correspondingly, the first device receives the first information from the fourth device on the third network.

[0335] Exemplarily, the fourth device is similar to the second device and may be a network device, as described in reference to FIG. 1a or FIG. 1b , which will not be described in detail.

[0336] It should be understood that the applicable scenario of Example 3 is as follows: deploying a first network, a second network, and a third network. The first network can be an A-IoT network, the second network can be an LTE network, and the third network can be an NB-IoT network. Alternatively, the first network can be an A-IoT network, the second network can be an NB-IoT network, and the third network can be an LTE network.

[0337] Exemplarily, the first information is introduced as follows: the first information is carried on a broadcast channel. That is, the first device receives the first information through the broadcast channel.

[0338] For example, in the above example 1, the second device of the first network sends the first information through the broadcast channel. Correspondingly, the first device receives the first information from the second device of the first network through the broadcast channel.

[0339] For another example, in Example 2 above, the third device on the second network sends the first information via a broadcast channel. Correspondingly, the first device receives the first information from the third device on the second network via the broadcast channel.

[0340] For another example, in Example 3 above, the fourth device on the third network sends the first information via a broadcast channel. Correspondingly, the first device receives the first information from the fourth device on the third network via the broadcast channel.

[0341] For the first device, after receiving the first information, the first device executes S1402:

[0342] S1402. The first device determines available resources or unavailable resources of the first network according to the first information.

[0343] For example, when the first information indicates available resources of the first network, the first device determines the available resources of the first network based on the first information. Correspondingly, the first device can also determine unavailable resources of the first network.

[0344] For another example, when the first information indicates unavailable resources of the first network, the first device determines the unavailable resources of the first network based on the first information. Correspondingly, the first device can also determine available resources of the first network.

[0345] Next, the first information is introduced through three examples (Example A, Example B, and Example C below):

[0346] Example A: The first information is related to the second network, where the second network may be an LTE network.

[0347] The introduction of Example A is as follows:

[0348] In a first aspect, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, or the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network.

[0349] Or, as a possible alternative description:

[0350] The first information indicates that the resources occupied by the first network are within the transmission bandwidth of the second network. Alternatively, the first information indicates that the resources occupied by the first network are not within the transmission bandwidth of the second network. In this case, the second network may or may not exist.

[0351] Exemplarily, the time-frequency resources occupied by the first network are within the time-frequency resources of the second network. It can be understood that the first network and the second network are deployed in-band.

[0352] For example, in the frequency domain, it can be understood that the first network and the second network occupy the same frequency band (or frequency point). For example, the frequency band occupied by the first network is 180KHz, and the frequency band occupied by the second network is 180KHz, and the frequency bands occupied by the two networks overlap.

[0353] For another example, regarding the frequency domain, it can be understood that the first network and the second network occupy part of the same frequency band (or frequency point). For example, the frequency band occupied by the first network is 180KHz, and the frequency band occupied by the second network is 2MHz. That is, the frequency band (or frequency point) occupied by the first network is included in the frequency band (or frequency point) occupied by the second network.

[0354] Exemplarily, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network. This can be understood as the first network and the second network being deployed in a non-in-band manner, such as a standalone deployment or a guardband deployment. Alternatively, the first network is deployed but the second network is not.

[0355] It should be understood that in the embodiments of the present application, the following descriptions have the same meaning and can be replaced by the same: the Xth network is not deployed and the Xth network does not exist. For example, the second network is not deployed and the second network does not exist are equivalent.

[0356] It should be understood that in the embodiments of the present application, the following descriptions have the same meaning and can be replaced by the same: the Xth network and the Yth network are deployed together, the Xth network and the Yth network coexist, and the Xth network and the Yth network are deployed.

[0357] Furthermore, the first information indicating that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network. The first state includes at least one of the following: the first device is in an idle state or a connected state, or the first device has connected to the first network.

[0358] The idle state means that the first device has not established an RRC connection with the network side, and the network side (such as a base station) has not stored the context of the first device. In addition, the idle state can also be referred to as the RRC idle state. In the embodiments of the present application, "idle state" and "RRC idle state" are the same concept and can be used interchangeably.

[0359] The connection state means that the first device has established an RRC connection with the network side, and data can be transmitted through the RRC connection. In addition, the connection state can also be referred to as the RRC connection state. In the embodiments of the present application, "connection state" and "RRC connection state" are the same concept and can be used interchangeably.

[0360] The fact that the first device has accessed the first network can be understood as that the first device has performed a random access (RA) process and established an RRC connection with the network side.

[0361] The first information indicating that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network. The first state can be described in the above paragraph and will not be repeated here.

[0362] In a second aspect, the first information indicates the number of antenna ports of the second network. The number of antenna ports of the second network includes the number of first antenna ports, the number of second antenna ports, and the number of third antenna ports. The status value of the first information includes a first value and a second value, the first value indicating the number of first antenna ports and / or the number of second antenna ports, and the second value indicating the number of third antenna ports. The resource mapping patterns corresponding to the first antenna port number and the second antenna port number are identical.

[0363] Furthermore, the status value of the first information also includes a third value. The first value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the second value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, and the third value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the third value is in a reserved state.

[0364] Exemplarily, the second network is an LTE network, and the antenna ports of the second network are antenna ports of CRS. The number of the first antenna port is 1, the number of the second antenna port is 2, and the number of the third antenna port is 4. The resource mapping pattern corresponding to the first antenna port number can be understood as the resource mapping pattern used when the first antenna port number is used to send CRS, as shown in Figure 9. In Figure 9, CRS occupies time domain symbols indexed as 0, 4, 7, and 11 in a time slot. The resource mapping pattern corresponding to the second antenna port number can be understood as the resource mapping pattern used when the second antenna port number is used to send CRS, as shown in Figure 10. In Figure 10, CRS occupies time domain symbols indexed as 0, 4, 7, and 11 in a time slot. The resource mapping pattern corresponding to the third antenna port number can be understood as the resource mapping pattern used when the third antenna port number is used to send CRS, as shown in Figure 11. In Figure 11, CRS occupies time domain symbols indexed as 0, 1, 4, 7, 8, and 11 in a time slot. In the embodiment of the present application, the resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports occupy the same time domain resources.

[0365] It should be noted that, in the embodiment of the present application, the time domain symbol includes an OFDM symbol. In a subframe, the index of the time domain symbol starts from 0.

[0366] Exemplarily, the status value of the first information is as shown in Table 1:

[0367] Table 1

[0368] In Table 1, taking the example of an A-IoT network as the first network and an LTE network as the second network, "in-band deployment" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network. "non-in-band deployment" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network.

[0369] In Table 1, "LTE antenna port number 1 / 2" indicates that the number of antenna ports for CRS is 1 or 2, that is, the first antenna port number or the second antenna port number. "LTE antenna port number 4" indicates that the number of antenna ports for CRS is 4, that is, the third antenna port number.

[0370] In Table 1, the status value of the first information is a two-bit bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (i.e., In-band in Table 1), and the number of antenna ports of CRS is 1 or 2, the status value of the first information is 10. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band), and the number of antenna ports of CRS is 4, the status value of the first information is 11. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network (i.e., non-In-band in Table 1), such as standalone, guardband, or no LTE, the status value of the first information is one of 00, 01 and reserved status.

[0371] It should be understood that in example A, the available resources of the first network do not include time-domain symbols occupied by the CRS, or the unavailable resources of the first network include time-domain symbols occupied by the CRS.

[0372] For example, the first resource set is recorded as the available resources of the first network. To avoid CRS, the first resource set includes time domain symbols identified by at least one of the following indices: 3, 5, 6, 9, 10, 12, and 13. The first resource set includes time domain resources occupied by the first information, such as the time domain resources occupied by the broadcast channel carrying the first information. Alternatively, the first resource set is also used to transmit data signals and / or control signals of the first network.

[0373] It should be understood that in Example A, when the third value indicates that the second network is not deployed, or the third value is in a reserved state, it can be understood that the available resources of the first network are all resources, or that the unavailable resources of the first network do not exist.

[0374] In a third aspect, the first information indicates the number of symbols of the control channel of the second network.

[0375] For example, taking three symbol quantities as an example, the symbol quantities indicated by the first information include a first symbol quantity, a second symbol quantity, and a third symbol quantity. The state value of the first information includes a fourth value, a fifth value, and a sixth value. The fourth value indicates the first symbol quantity, the fifth value indicates the second symbol quantity, and the sixth value indicates the third symbol quantity.

[0376] In an embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, e.g., the control channel occupies the time domain symbol indexed 0 in a subframe. The second symbol number may be 2, e.g., the control channel occupies the time domain symbols indexed 0 and 1 in a subframe. The third symbol number may be 3, e.g., the control channel occupies the time domain symbols indexed 0, 1, and 2 in a subframe.

[0377] Furthermore, the status value of the first information also includes a seventh value. Among them, the fourth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the fifth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the sixth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, and the seventh value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the seventh value is reserved.

[0378] Exemplarily, the status value of the first information is as shown in Table 2:

[0379] Table 2

[0380] In Table 2, taking the example of an A-IoT network as the first network and an LTE network as the second network, "In-band" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network. "Non-in-band" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network.

[0381] In Table 2, "Number of symbols occupied by control channel 1" indicates the first number of symbols, "Number of symbols occupied by control channel 2" indicates the second number of symbols, and "Number of symbols occupied by control channel 3" indicates the third number of symbols.

[0382] In Table 2, the status value of the first information is a two-bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band in Table 2) and the number of symbols occupied by the control channel is 1 (i.e., the first symbol number is 1), the status value of the first information is 00. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band in Table 2) and the number of symbols occupied by the control channel is 2 (i.e., the second symbol number is 2), the status value of the first information is 01. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band in Table 2) and the number of symbols occupied by the control channel is 3 (i.e., the third symbol number is 3), the status value of the first information is 10. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network (such as Non-In-band in Table 2), such as in standalone, guardband, or no LTE, the status value of the first information is one of 11 and reserved.

[0383] For another example, taking two symbol quantities as an example, that is, the symbol quantities include a first symbol quantity and a second symbol quantity, the state value of the first information includes a fourth value and a fifth value, wherein the fourth value indicates the first symbol quantity and the fifth value indicates the second symbol quantity.

[0384] In an embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, such as the control channel occupies the time domain symbol indexed as 0 in a subframe. The second symbol number may be 2, such as the control channel occupies the time domain symbols indexed as 0 and 1 in a subframe.

[0385] Furthermore, the status value of the first information also includes a seventh value. The fourth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the fifth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, and the seventh value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the seventh value is in a reserved state.

[0386] Exemplarily, the status value of the first information is as shown in Table 3:

[0387] Table 3

[0388] In Table 3, taking the example of an A-IoT network as the first network and an LTE network as the second network, "In-band" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network. "Non-in-band" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network.

[0389] In Table 3, "Number of symbols occupied by the control channel 1" indicates the first number of symbols, and "Number of symbols occupied by the control channel 2" indicates the second number of symbols.

[0390] In Table 3, the status value of the first information is a two-bit bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band in Table 3), and the number of symbols occupied by the control channel is 1 (that is, the first symbol number is 1), the status value of the first information is 00. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band in Table 3), and the number of symbols occupied by the control channel is 2 (that is, the second symbol number is 2), the status value of the first information is 01. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network (such as non-In-band in Table 3), such as standalone, guardband, or no LTE, the status value of the first information is 11 and one of the reserved states.

[0391] For another example, taking a number of symbols as an example, that is, the number of symbols includes a first number of symbols, the state value of the first information includes a fourth value, wherein the fourth value indicates the first number of symbols.

[0392] In the embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, for example, the control channel occupies a time domain symbol with an index of 0 in a subframe.

[0393] Furthermore, the status value of the first information also includes a seventh value. The fourth value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network, the seventh value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network, or the second network is not deployed, or the seventh value is in a reserved state.

[0394] Exemplarily, the status value of the first information is as shown in Table 4:

[0395] Table 4

[0396] In Table 4, taking the example of an A-IoT network as the first network and an LTE network as the second network, "In-band" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network. "Non-in-band" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network.

[0397] In Table 4, "Number of symbols occupied by control channel 1" indicates the first number of symbols.

[0398] In Table 4, taking the case where the first network is an A-IoT network and the second network is an LTE network as an example, the state value of the first information is a two-bit bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network (such as In-band), and the number of symbols occupied by the control channel is 1 (that is, the first symbol number is 1), the state value of the first information is 00. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network (such as non-In-band), such as standalone, guardband, or no LTE, the state value of the first information is 11 and one of the reserved states.

[0399] It should be understood that in example A, the available resources of the first network do not include time domain symbols occupied by the control channel, or the unavailable resources of the first network include time domain symbols occupied by the control channel.

[0400] For example, the first resource set is recorded as the available resources of the first network. The first resource set includes time domain symbols identified by a first index. The first index includes 0, 1, and 2, or the first index includes 1 and 2, or the first index includes 2.

[0401] Specifically, when the time-frequency resources occupied by the A-IoT network are in addition to the time-frequency resources occupied by the LTE network, the first index includes 0, 1, and 2. When the control channel occupies 1 time domain symbol (such as the control channel occupies the time domain symbol with index 0 in a subframe), the first index includes 1 and 2, but does not include 0. When the control channel occupies 2 time domain symbols (such as the control channel occupies the time domain symbols with indexes 0 and 1 in a subframe), the first index includes 2, but does not include 0 and 1. When the control channel occupies 3 time domain symbols (such as the control channel occupies the time domain symbols with indexes 0, 1, and 2 in a subframe), the first index does not include 0, 1, and 2.

[0402] It should be understood that in example A, the state value of the first information includes the first value, the second value, the fourth value, the fifth value, or the sixth value, and the first network and the second network are jointly deployed or coexist.

[0403] It should be understood that in example A, the status value of the first information includes the third value or the seventh value, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network or the second network is not deployed.

[0404] It should be understood that in Example A, when the seventh value indicates that the second network is not deployed, or the seventh value is in a reserved state, it can be understood that the available resources of the first network are all resources, or that the unavailable resources of the first network do not exist.

[0405] In Example B, the first information is related to a second network and a third network, where the second network may be an LTE network and the third network may be an NB-IoT network.

[0406] Example B is described as follows:

[0407] In the fourth aspect, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network, or the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and outside the time-frequency resources of the third network.

[0408] It's easy to understand that the phrase "the time-frequency resources occupied by the first network are within the time-frequency resources of the second network" can be replaced by the phrase "the resources occupied by the first network are within the transmission bandwidth of the second network." The phrase "the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network" can be replaced by the phrase "the resources occupied by the first network are not within the transmission bandwidth of the second network." In this case, the second network may or may not exist.

[0409] Furthermore, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network, including: the first information indicates that in the first state, the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network. The first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, including: the first information indicates that in the first state, the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network. The first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network, including: the first information indicates that in the first state, the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network and within the time-frequency resources of the third network. The first information indicating that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network includes: the first information indicating that, in a first state, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network. The first state includes at least one of the following: the first device is in an idle state or a connected state, or the first device is connected to the first network. For details, please refer to the introduction of Example A and will not be repeated here.

[0410] In a fifth aspect, the first information indicates the number of antenna ports of the second network. The number of antenna ports of the second network includes the number of first antenna ports, the number of second antenna ports, and the number of third antenna ports. The status value of the first information includes a first value, a second value, a third value, and a fourth value. The first value indicates the number of first antenna ports and / or the number of second antenna ports, and the second value indicates the number of first antenna ports and / or the number of second antenna ports. The third value indicates the number of third antenna ports, and the fourth value indicates the number of third antenna ports.

[0411] Furthermore, the first value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network.

[0412] The second value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, or the second value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and the third network is not deployed.

[0413] The third value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and within the time-frequency resources of the third network.

[0414] The fourth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and outside the time-frequency resources of the third network, or the fourth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network and the third network is not deployed.

[0415] Exemplarily, the second network is an LTE network, and the antenna ports of the second network are antenna ports of the CRS. For example, the number of the first antenna port is 1, the number of the second antenna port is 2, and the number of the third antenna port is 4. For details, see the introduction of Example A, which will not be repeated here.

[0416] Exemplarily, the status value of the first information is as shown in Table 5:

[0417] Table 5

[0418] In Table 5, for example, if the first network is an A-IoT network, the second network is an LTE network, and the third network is an NB-IoT network, "LTE-In-band" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network. "Reused with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the NB-IoT network. "Not reused with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the NB-IoT network. In this case, the NB-IoT network may or may not exist.

[0419] In Table 5, "LTE antenna port number 1 / 2" indicates that the number of antenna ports for CRS is 1 or 2, that is, the first antenna port number or the second antenna port number. "LTE antenna port number 4" indicates that the number of antenna ports for CRS is 4, that is, the third antenna port number.

[0420] In Table 5, the status value of the first information is a three-bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network and are located within the time-frequency resources occupied by the NB-IoT network, and the number of antenna ports of the CRS is 1 or 2, the status value of the first information is 000. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network and are located within the time-frequency resources occupied by the NB-IoT network, and the number of antenna ports of the CRS is 4, the status value of the first information is 001. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network and are located outside the time-frequency resources occupied by the NB-IoT network, and the number of antenna ports of the CRS is 1 or 2, the status value of the first information is 010. When the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the LTE network and are located outside the time-frequency resources occupied by the NB-IoT network, and the number of antenna ports of the CRS is 4, the status value of the first information is 011.

[0421] In a sixth aspect, the first information indicates the number of antenna ports of the third network. The number of antenna ports of the third network includes the number of fourth antenna ports and the number of fifth antenna ports. The status value of the first information includes a fifth value, and the fifth value indicates the number of fourth antenna ports and / or the number of fifth antenna ports. The resource mapping patterns corresponding to the fourth antenna port number and the fifth antenna port number are the same.

[0422] Furthermore, the status value of the first information also includes a sixth value. The fifth value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and within the time-frequency resources of the third network, or the fifth value indicates that the second network is not deployed and the time-frequency resources occupied by the first network are within the time-frequency resources of the third network.

[0423] The sixth value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and outside the time-frequency resources of the third network, or, the sixth value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network and the third network is not deployed, or, the sixth value indicates that the second network is not deployed and the time-frequency resources occupied by the first network are outside the time-frequency resources of the third network, or, the sixth value indicates that the second network is not deployed and the third network is not deployed.

[0424] Exemplarily, the third network is an NB-IoT network, and the antenna port of the third network is the antenna port of the NRS. The number of the fourth antenna port is 1, and the number of the fifth antenna port is 2. The resource mapping pattern corresponding to the fourth antenna port number can be understood as the resource mapping pattern used when the fourth antenna port number is used to send the NRS, as shown in Figure 12. In Figure 12, the NRS occupies the time domain symbols indexed as 5, 6, 12, and 13 in a time slot. The resource mapping pattern corresponding to the fifth antenna port number can be understood as the resource mapping pattern used when the fifth antenna port number is used to send the NRS, as shown in Figure 13. In Figure 13, the NRS occupies the time domain symbols indexed as 5, 6, 12, and 13 in a time slot. In an embodiment of the present application, the resource mapping patterns corresponding to the fourth antenna port number and the fifth antenna port number occupy the same time domain resources.

[0425] Exemplarily, the status value of the first information is as shown in Table 6:

[0426] Table 6

[0427] In Table 6, taking the example of an A-IoT network as the first network, an LTE network as the second network, and an NB-IoT network as the third network, "Not LTE-In-band" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network. "Multiplexed with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the NB-IoT network. "Not Multiplexed with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the NB-IoT network.

[0428] In Table 6, “the number of antenna ports of NB-IoT is 1 / 2” indicates that the number of antenna ports of NRS is 1 or 2, that is, the fourth antenna port number or the fifth antenna port number.

[0429] In Table 6, the status value of the first information is a three-bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network and within the time-frequency resources occupied by the NB-IoT network, the status value of the first information is 100. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the LTE network and outside the time-frequency resources occupied by the NB-IoT network, the status value of the first information is 101.

[0430] It should be understood that in example B, the available resources of the first network do not include the time domain symbols occupied by the CRS and the time domain symbols occupied by the NRS, or the unavailable resources of the first network include the time domain symbols occupied by the CRS and the time domain symbols occupied by the NRS.

[0431] For example, the second resource set is recorded as the available resources of the first network. To avoid CRS and NRS, the second resource set includes time domain symbols identified by at least one of the following indices: 3, 9, and 10. The second resource set includes the time domain resources occupied by the first information, such as the time domain resources occupied by the broadcast channel carrying the first information. Alternatively, the second resource set is also used to transmit data signals and / or control signals of the first network.

[0432] In a seventh aspect, the first information indicates the number of symbols of the control channel of the second network.

[0433] For example, taking three symbols as an example, the symbol quantity includes a first symbol quantity, a second symbol quantity, and a third symbol quantity. The state value of the first information includes a seventh value, an eighth value, and a ninth value. The seventh value indicates the first symbol quantity, the eighth value indicates the second symbol quantity, and the ninth value indicates the third symbol quantity.

[0434] In an embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, e.g., the control channel occupies the time domain symbol indexed 0 in a subframe. The second symbol number may be 2, e.g., the control channel occupies the time domain symbols indexed 0 and 1 in a subframe. The third symbol number may be 3, e.g., the control channel occupies the time domain symbols indexed 0, 1, and 2 in a subframe.

[0435] Furthermore, the status value of the first information also includes a tenth value. The seventh value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the eighth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the ninth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the tenth value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the tenth value indicates a reserved state.

[0436] Exemplarily, the status value of the first information is shown in Table 2 and will not be repeated here.

[0437] For another example, taking two symbols as an example, the number of symbols includes a first symbol number and a second symbol number. The state value of the first information includes a seventh value and an eighth value. The seventh value indicates the first symbol number, and the eighth value indicates the second symbol number.

[0438] In an embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, such as the control channel occupies the time domain symbol indexed as 0 in a subframe. The second symbol number may be 2, such as the control channel occupies the time domain symbols indexed as 0 and 1 in a subframe.

[0439] Furthermore, the status value of the first information also includes a tenth value. The seventh value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the eighth value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, and the tenth value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the tenth value indicates a reserved state.

[0440] Exemplarily, the status value of the first information is shown in Table 3 and will not be repeated here.

[0441] For another example, taking the two-symbol example, the number of symbols includes a first symbol number, and the state value of the first information includes a seventh value, wherein the seventh value indicates the first symbol number.

[0442] In the embodiment of the present application, the control channel may include a PDCCH. The first symbol number may be 1, for example, the control channel occupies a time domain symbol with an index of 0 in a subframe.

[0443] Furthermore, the status value of the first information also includes a tenth value. The seventh value indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, the tenth value indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network, or the second network is not deployed, or the tenth value is in a reserved state.

[0444] Exemplarily, the status value of the first information is shown in Table 4 and will not be repeated here.

[0445] It should be understood that in example B, the available resources of the first network do not include time domain symbols occupied by the control channel, or the unavailable resources of the first network include time domain symbols occupied by the control channel.

[0446] For example, the second resource set is recorded as the available resources of the first network. The second resource set includes time domain symbols identified by a second index. The second index includes 0, 1, and 2, or the second index includes 1 and 2, or the second index includes 2.

[0447] For example, when the time-frequency resources occupied by the A-IoT network are in addition to the time-frequency resources occupied by the LTE network, the second index includes 0, 1, and 2. When the control channel occupies one time domain symbol (such as the control channel occupies the time domain symbol with index 0 in a subframe), the second index includes 1 and 2, but does not include 0. When the control channel occupies two time domain symbols (such as the control channel occupies the time domain symbols with indexes 0 and 1 in a subframe), the second index includes 2, but does not include 0 and 1. When the control channel occupies three time domain symbols (such as the control channel occupies the time domain symbols with indexes 0, 1, and 2 in a subframe), the second index does not include 0, 1, and 2.

[0448] It should be understood that in example B, the state value of the first information includes the first value, the second value, the third value, the fourth value, the fifth value, the seventh value, the eighth value or the ninth value, and the first network and the second network are jointly deployed or coexist.

[0449] It should be understood that in example B, the status value of the first information includes the sixth value or the tenth value, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network or the second network is not deployed.

[0450] It should be understood that in Example B, when the second network is not deployed, it can be understood that there is no need to avoid the time and frequency resources occupied by the second network.

[0451] It should be understood that in example B, the state value of the first information includes a first value, a third value, and a fifth value, and the first network and the third network are co-deployed or co-exist.

[0452] It should be understood that in example B, the status value of the first information includes the second value, the fourth value or the sixth value, the time-frequency resources occupied by the first network are outside the time-frequency resources of the third network or the third network is not deployed.

[0453] It should be understood that in Example B, when the third network is not deployed, it can be understood that there is no need to avoid the time and frequency resources occupied by the third network.

[0454] Example C: The first information is related to the second network, where the second network may be an NB-IoT network.

[0455] The introduction of Example C is as follows:

[0456] In the eighth aspect, the first information indicates that the time-frequency resources occupied by the first network are located within the time-frequency resources of the second network, or the first information indicates that the time-frequency resources occupied by the first network are located outside the time-frequency resources of the second network. For details, see the introduction of the first aspect in Example A and will not be repeated here.

[0457] In a ninth aspect, the first information indicates the number of antenna ports of the second network, where the number of antenna ports of the second network includes a first number of antenna ports and a second number of antenna ports. The status value of the first information includes a first value, where the first value indicates the first number of antenna ports and / or the second number of antenna ports. The resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports are the same.

[0458] Furthermore, the status value of the first information also includes a second value. The first value indicates that the time-frequency resources occupied by the first network are within the time-frequency resources of the second network, the second value indicates that the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network, or the second network is not deployed, or the second value is in a reserved state.

[0459] Exemplarily, the second network is an NB-IoT network, and the antenna ports of the second network are the antenna ports of the NRS. The number of first antenna ports is 1, and the number of second antenna ports is 2. The resource mapping pattern corresponding to the first number of antenna ports can be understood as the resource mapping pattern used when the first number of antenna ports is used to send the NRS, as shown in Figure 12. In Figure 12, the NRS occupies the time domain symbols indexed as 5, 6, 12, and 13 in a time slot. The resource mapping pattern corresponding to the second number of antenna ports can be understood as the resource mapping pattern used when the second number of antenna ports is used to send the NRS, as shown in Figure 13. In Figure 13, the NRS occupies the time domain symbols indexed as 5, 6, 12, and 13 in a time slot. In an embodiment of the present application, the resource mapping patterns corresponding to the first number of antenna ports and the second number of antenna ports occupy the same time domain resources.

[0460] Exemplarily, the status value of the first information is as shown in Table 7:

[0461] Table 7

[0462] In Table 7, taking the example of an A-IoT network as the first network and an NB-IoT network as the second network, "Reuse with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the NB-IoT network. "Not reuse with NB-IoT" indicates that the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the NB-IoT network.

[0463] In Table 7, “the number of antenna ports of NB-IoT is 1 / 2” indicates that the number of antenna ports of the NRS is 1 or 2, that is, the number of first antenna ports or the number of second antenna ports.

[0464] In Table 7, the status value of the first information is a two-bit value. Specifically, when the time-frequency resources occupied by the A-IoT network are within the time-frequency resources occupied by the NB-IoT network, the status value of the first information is 00. When the time-frequency resources occupied by the A-IoT network are outside the time-frequency resources occupied by the NB-IoT network, the status value of the first information is one of 01, 10, 11, and the reserved state.

[0465] It should be understood that in Example C, the available resources of the first network do not include the time-domain symbols occupied by the NRS, or the unavailable resources of the first network include the time-domain symbols occupied by the NRS.

[0466] For example, the third resource set is recorded as the available resources of the first network. To avoid NRS, the third resource set includes time domain symbols identified by at least one of the following indices: 0, 1, 2, 3, 4, 7, 8, 9, 10, and 11. The third resource set includes the time domain resources occupied by the first information, such as the time domain resources occupied by the broadcast channel carrying the first information. Alternatively, the third resource set is also used to transmit data signals and / or control signals of the first network.

[0467] It should be understood that in Example C, the state value of the first information includes the first value, and the first network and the second network are jointly deployed or coexist.

[0468] It should be understood that in example C, the status value of the first information includes the second value, and the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network or the second network is not deployed.

[0469] It should be understood that in Example C, when the second value indicates that the second network is not deployed, or the second value is in a reserved state, it can be understood that the available resources of the first network are all resources, or that the unavailable resources of the first network do not exist.

[0470] In some embodiments, as one approach, the first information occupies at least one subframe. In other words, all time-domain symbols in a subframe can be used to transmit the first information. Alternatively, as another approach, the first information occupies at least one radio frame. In other words, all time-domain symbols in a radio frame can be used to transmit the first information. Both of the above approaches can be understood as the first device being allocated contiguous resources in the time domain.

[0471] That is to say, the resources used to transmit the first information are not occupied by other networks, such as the LTE network, the NB-IoT network, and the NR network, thereby effectively ruling the interference of the broadcast channel, the data channel, and the control channel in the above networks (i.e., the LTE network, the NB-IoT network, and the NR network) with the first information, and helping to ensure the transmission performance of the first information.

[0472] In some embodiments, when the first device receives the first information, the time-frequency resources occupied by the first network are outside the time-frequency resources of the second network. This means that when the first device receives the first information, the first network and the second network are deployed non-in-band, effectively preventing interference from the second network's broadcast channel, data channel, and control channel on the first information, thereby ensuring transmission performance of the first information.

[0473] Optionally, after the first device receives the first information, the deployment mode of the first network and the second network may change, such as changing from non-in-band deployment to in-band deployment. For details, see the introduction to the first state in Example A and will not be repeated here.

[0474] In some embodiments, as shown in FIG15 , the resource indication method 1400 of the embodiment of the present application further includes the following operations:

[0475] S1411. The first device receives second information.

[0476] The second information indicates the first resource and / or the second resource.

[0477] Exemplarily, the first resource is continuous in the frequency domain and is used by the first device to access the first network. This can be understood as the first device accessing the first network using the first resource. For example, the first device performs a random access procedure on the first resource to access the first network. Because the first resource is continuous in the frequency domain, the impact of other networks on information transmission on the first resource is effectively avoided, helping to reduce the probability of access interruption and access latency.

[0478] Furthermore, the first resource is continuous in the time domain. Since the first resource is continuous in the time domain, the influence of other networks on the information transmission on the first resource can be avoided, which helps to further reduce the probability of access process being interrupted and reduce access delay.

[0479] Exemplarily, the second resource is continuous in the frequency domain and is used to synchronize the first device with the first network. This means that the second device on the first network transmits a synchronization signal on the second resource. In response, the first device receives the synchronization signal on the first resource, thereby synchronizing with the first network. Because the second resource is continuous in the frequency domain, it effectively mitigates the impact of other networks on information transmission on the second resource, helping to reduce the probability of synchronization interruptions and synchronization latency.

[0480] Furthermore, the second resource is continuous in the time domain. Since the second resource is continuous in the time domain, the influence of other networks on the information transmission on the second resource can be avoided, which helps to further reduce the probability of the synchronization process being interrupted and reduce the synchronization delay.

[0481] It should be noted that in the embodiments of the present application, the Xth value and the Yth value are different. Taking bit values ​​as an example, when two bits are used, the Xth value can be 00, and the Yth value can be one of 01, 10, and 11. When three bits are used, the Xth value can be 001, and the Yth value can be 010, etc.

[0482] It should be noted that in the embodiments of the present application, for the introduction of the time domain, such as time domain symbols, OFDM symbols, time slots, subframes, and radio frames, please refer to the introduction of the relevant 3GPP technical specifications, and no further description is given.

The chip system may be composed of a chip, or may include a chip and other discrete components.

[0484] It is understandable that, in order to realize the above functions, the communication device includes hardware structures and / or software modules corresponding to the execution of each function.

[0485] 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 modules can be implemented in the form of hardware or in the form of software functional modules. It should be pointed out that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. In actual implementation, there may be other division methods.

[0509] Since the communication device 160 provided in this embodiment can execute the above method, the technical effects that can be obtained can refer to the above method embodiments and will not be repeated here.

[0510] As a possible product form, the first device, the second device, the third device or the fourth device described in the embodiments of the present application can also be implemented using the following: one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits that can perform the various functions described throughout this application.

[0511] As another possible product form, the first device, second device, third device or fourth device described in the embodiment of the present application can be implemented by a general bus architecture. For ease of explanation, refer to Figure 17, which is a structural diagram of a communication device 1700 provided in an embodiment of the present application, wherein the communication device 1700 includes a processor 1701 and a transceiver 1702. The communication device 1700 can be a first device, or a chip or chip system therein; or, the communication device 1700 can be a second device, or a chip or module therein; or, the communication device 1700 can be a third device, or a chip or module therein; or, the communication device 1700 can be a fourth device, or a chip or module therein. Figure 17 only shows the main components of the communication device 1700. In addition to the processor 1701 and the transceiver 1702, the communication device 1700 can further include a memory 1703, and an input and output device (not shown).

[0512] Optionally, processor 1701 is primarily used to process communication protocols and communication data, as well as control the entire communication device, execute software programs, and process software program data. Memory 1703 is primarily used to store software programs and data. Transceiver 1702 may include a radio frequency circuit and an antenna. The radio frequency circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as a touch screen, display, and keyboard, are primarily used to receive user input and output data to the user.

[0513] Optionally, the processor 1701 , the transceiver 1702 , and the memory 1703 may be connected via a communication bus.

[0514] When the communication device is powered on, the processor 1701 can read the software program in the memory 1703, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 1701 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1701. The processor 1701 converts the baseband signal into data and processes the data.
