Description

Communication method and communication apparatus

[0001] This application claims priority from the Chinese patent application No. 202411248425.4 filed on September 5, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communications, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] In the current cell concept defined by the communication system, each cell can contain uplink carriers and downlink carriers at the same time, and the number of uplink carriers and downlink carriers is generally 1 respectively. With the rise of terminal service demand, the frequency domain resources required for transmission services can be provided through the carrier aggregation (CA) mode.

[0004] However, in the carrier aggregation scheme, the frequency domain resource configuration and information transmission are performed in the carrier granularity, which has poor flexibility and low resource utilization. Therefore, how to improve the flexibility of frequency domain resource configuration has become a problem to be solved. SUMMARY

[0005] The present application provides a communication method to improve the flexibility of frequency domain resource configuration.

[0006] In a first aspect, a communication method is provided, which can be executed by a first communication device (e.g., a terminal device), or by a component (e.g., a processor, a chip, or a chip system, such as a circuit or a chip responsible for communication function in the first communication device (e.g., a Modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core)) of the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. For ease of description, the following description is given with the first communication device as an example.

[0007] The method can include: receiving first indication information from a second communication device, the first indication information indicating a frequency domain location and a frequency domain size of a first frequency domain resource, the first frequency domain resource including all or part of each carrier in at least one carrier; and performing information transmission on the first frequency domain resource.

[0008] Based on the technical solution, the first communication device can learn the frequency domain position and the frequency domain size of the first frequency domain resource configured by the second communication device for the first communication device based on the received first indication information, and the first frequency domain resource includes all or part of each carrier in at least one carrier, that is, the frequency domain resource configured by the second communication device for the first communication device can include one or more carriers, and can include part or all of a certain carrier, without limiting the configuration granularity of one carrier, thereby realizing flexible frequency domain resource configuration. And the frequency domain resource configuration process can include part of a certain carrier, thereby more effectively utilizing scattered frequency domain resources and edge frequency domain resources.

[0009] In combination with the first aspect, in some implementations of the first aspect, the first frequency domain resource includes all or part of each carrier in the plurality of carriers.

[0010] Based on the technical solution, the first frequency domain resource can include part or all of each carrier in the plurality of carriers, supporting multi-carrier configuration, which can improve the bandwidth width of the frequency domain resource compared to single-carrier configuration.

[0011] In combination with the first aspect, in some implementations of the first aspect, the plurality of carriers includes a first carrier and a second carrier, and the first carrier and the second carrier satisfy at least one of the following conditions: the first carrier and the second carrier are two carriers that are continuous or discontinuous in a first frequency band; or the first carrier is located in a first frequency band and the second carrier is located in a second frequency band, the first frequency band and the second frequency band are continuous in the frequency domain, and the first carrier and the second carrier are continuous in the frequency domain; or the first carrier is located in a first frequency band and the second carrier is located in a second frequency band, and the first carrier and the second carrier are discontinuous in the frequency domain.

[0012] Based on the technical solution, in the case that the first frequency domain resource contains resources on multiple carriers, the multiple carriers can be continuous or discontinuous in the frequency domain across the interval between the multiple carriers, and the configuration of the first frequency domain resource is not limited too much, thereby improving the flexibility of the scheme.

[0013] In some implementations of the first aspect, the transmitting or receiving the information on the first frequency domain resource comprises: transmitting or receiving the information on the first frequency domain resource based on at least one of a first transmission manner, a second transmission manner, a third transmission manner, or a fourth transmission manner, wherein the first transmission manner is transmitting or receiving the information on the first carrier or the second carrier; the second transmission manner is transmitting or receiving the information on the first carrier and the second carrier respectively, a first part of the information is mapped to the first carrier, and a second part of the information is mapped to the second carrier, and the first carrier and the second carrier are continuous in frequency domain; the third transmission manner is transmitting or receiving the information on the first carrier and the second carrier respectively, a first part of the information is mapped to the first carrier, and a second part of the information is mapped to the second carrier, and the first carrier and the second carrier are discontinuous in frequency domain; and the fourth transmission manner is transmitting or receiving the information on the first carrier and the second carrier, and all or part of a second frequency domain resource, the first carrier and the second carrier are discontinuous in frequency domain, and the second frequency domain resource is a frequency domain resource between the first carrier and the second carrier.

[0014] According to the above technical solution, the first communication device can transmit or receive information on the first frequency domain resource, and the information can be mapped in any carrier or multiple carriers in the first frequency domain resource. The first communication device can support different transmission manners for information transmission, thereby improving the utilization rate of frequency domain resources.

[0015] In some implementations of the first aspect, a bandwidth of the first frequency domain resource is less than or equal to a working bandwidth of the first communication device, wherein the working bandwidth of the first communication device can be understood as a bandwidth that can be received or transmitted by the first communication device at one time.

[0016] In some implementations of the first aspect, before the transmitting or receiving the information on the first frequency domain resource, the method further comprises: determining whether a first condition is met; if the first condition is met, determining to transmit or receive the information on the first frequency domain resource based on at least one of the first transmission manner, the second transmission manner, the third transmission manner, or the fourth transmission manner; and if the first condition is not met, determining to transmit or receive the information on the first frequency domain resource based on at least one of the first transmission manner, the second transmission manner, or the third transmission manner, wherein the first condition comprises at least one of: a first frequency domain interval between the first carrier and the second carrier is less than a first threshold, a ratio of the first frequency domain interval to the bandwidth of the first frequency domain resource is less than a second threshold, or a signal strength corresponding to the first frequency domain interval is less than a third threshold.

[0017] Based on the technical solution, the first communication device can determine whether the first condition is met before transmitting information on the multiple carriers included in the first frequency domain resource, and the transmission mode is constrained by the first condition, so that the first communication device can select a more appropriate transmission mode for information transmission. For example, the signal strength corresponding to the frequency domain interval between adjacent carriers is less than a certain threshold, and the power does not need to be backed off when transmitting information uplink, thereby improving the transmission performance.

[0018] In some implementations of the first aspect, the second frequency domain interval between any two adjacent carriers in the first frequency domain resource is less than a first threshold, the ratio of the second frequency domain interval to the bandwidth of the first frequency domain resource is less than a second threshold, or the signal strength corresponding to the second frequency domain interval is less than a third threshold.

[0019] Based on the technical solution, the second communication device configures the first frequency domain resource for the first communication device, and the size of the frequency domain interval between adjacent carriers included in the first frequency domain resource and / or the signal strength corresponding to the frequency domain interval meets a certain condition.

[0020] In some implementations of the first aspect, the method further includes: receiving second indication information from the second communication device, the second indication information being used to indicate the signal strength corresponding to part or all of the frequency domain intervals between adjacent carriers in the first frequency domain resource; measuring the signal strength corresponding to the frequency domain intervals between adjacent carriers in the first frequency domain resource to obtain a measurement result; and reporting the measurement result to the second communication device.

[0021] Based on the technical solution, the second communication device can instruct the first communication device to measure the signal strength through the second indication information, so that the second communication device can determine the bandwidth of the first frequency domain resource based on the capability of the second communication device, and effectively utilize the capability of the second communication device.

[0023] Based on the technical solution, there are multiple ways for the first indication information to indicate the frequency domain location and the frequency domain size of the first frequency domain resource, thereby improving the flexibility of the solution.

[0024] In some implementations of the first aspect, the information includes at least one of data, a signal, or a channel.

[0025] According to the above technical solution, the information transmitted by the first communication device on the first frequency domain resource can be data, a signal, or a channel to be transmitted. The object transmitted by the first communication device is not limited.

[0026] In some implementations of the first aspect, the data is one transport block; the signal is a signal determined according to a set of configuration parameters; and the channel is one channel.

[0027] In some implementations of the first aspect, the method further includes receiving third indication information from the second communication device, the third indication information indicating a control resource corresponding to the first frequency domain resource, wherein the control resource is used for receiving and detecting a physical downlink control channel (PDCCH) used for scheduling or activating information transmission on the at least one carrier.

The to-be-indicated information can also be only indicated in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, a protocol stipulates), thereby reducing the indication overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly indicated, so as to reduce the indication overhead caused by separately indicating the same information.

In addition, in the embodiments of the present application, "first", "second", and various numerical numbers (for example, "#1", "#2", etc.) are only for the convenience of description and do not limit the scope of the embodiments of the present application. The size of the serial number of each process below does not mean the execution order, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. It should be understood that the objects thus described can be interchanged under appropriate circumstances, so as to be able to describe schemes other than the embodiments of the present application. In addition, in the embodiments of the present application, the words such as "S410" are only for the convenience of description and do not limit the order of execution steps.

[0085] The technical solutions in this application will be described below in conjunction with the drawings.

[0087] Exemplarily, the satellite communication system can be integrated with a conventional mobile communication system.

[0088] FIG. 1 shows a schematic diagram of a communication system to which embodiments of the present application can be applied. The communication system includes at least one network device and at least one terminal. The terminal includes a ground mobile terminal, a drone, etc. When the network device or the terminal moves rapidly, the transceiver will move relatively, resulting in Doppler shift and sampling point timing drift. The network device and the terminal are sometimes referred to as communication apparatuses. For example, the network device in FIG. 1 can be understood as a communication apparatus with a base station function, and the terminal can be understood as a communication apparatus with a terminal function.

[0089] It should be understood that FIG. 1 is a simple illustration of a communication scenario to which embodiments of the present application can be applied, taking the communication between the network device and the terminal device, and the communication between the network device and the core network device as examples, without limiting other scenarios to which embodiments of the present application can be applied. It should also be understood that FIG. 1 is a simplified schematic diagram for the purpose of understanding, and other network devices or other terminal devices can also be included in the communication system, which are not shown in FIG. 1.

[0090] The terminal in embodiments of the present application can also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The terminal is usually provided with a communication module, circuit or chip for performing corresponding communication functions, and is also configured with program instructions for performing corresponding communication functions.

[0091] The network device in embodiments of the present application can also be referred to as an access network device, a radio access network (RAN) entity or an access node, etc., and constitutes part of the communication system to help the terminal realize wireless access. The communication system can include multiple network devices, which can be nodes of the same type or nodes of different types.

[0092] In a possible scenario, the network device can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a base station in a future mobile communication system (next generation NodeB, gNB), or an access node in a WiFi system, etc. The network device can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a radio controller. Optionally, the network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0093] In another possible scenario, a plurality of network devices cooperate to assist a terminal to implement wireless access, and different network devices respectively implement part of the functions of a base station. For example, the network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The CU node and the DU node split the protocol layers of the gNB, and the functions of part of the protocol layers are placed in the CU for centralized control, and the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU.

[0094] The CU is deployed with the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, and the service data adaptation protocol (SDAP) layer in the protocol stack; and the DU is deployed with the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY) in the protocol stack.

[0095] Among them, the CU has the processing capability of RRC, PDCP and SDAP. The DU has the processing capability of RLC, MAC and PHY.

[0096] It should be understood that the above division (or segmentation) of functions is only an example and does not limit the CU and DU of the present application. That is, there can be other ways of dividing the functions between the CU and the DU, and the embodiments of the present application do not limit this.

[0097] The functions of the CU can be implemented by one entity or by different entities. For example, the functions of the CU can be further divided, for example, by separating the control plane (CP) and the user plane (UP), i.e., the control plane of the CU (CU-CP) and the user plane of the CU (CU-UP). The CU-CP and the CU-UP can be implemented by different functional entities, and the CU-CP and the CU-UP can be coupled with the DU to jointly complete the functions of the network device. The control plane of the CU (CU-CP) can further include a further divided architecture, i.e., the CU-CP is further divided into CU-CP1 and CU-CP2. The CU-CP1 includes various radio resource management functions, and the CU-CP2 includes only the RRC function and the PDCP-control (C) function (i.e., the basic function of the control plane signaling at the PDCP layer).

[0098] In one possible way, the CU-CP is responsible for the control plane function, mainly including RRC and PDCP-C. The PDCP-C is mainly responsible for the encryption and decryption of the control plane data, integrity protection, data transmission, etc. The CU-UP is responsible for the user plane function, mainly including SDAP and PDCP-user (U). The SDAP is mainly responsible for processing the data of the core network and mapping the data flow to the bearer. The PDCP-U is mainly responsible for the encryption and decryption of the data plane, integrity protection, header compression, sequence number maintenance, data transmission, etc. The CU-CP and the CU-UP are connected through an E1 interface. The CU-CP is connected to the core network through an Ng interface. The CU-CP is connected to the DU through an F1-C (control plane). The CU-UP is connected to the DU through an F1-U (user plane). Of course, there is also a possible implementation that the PDCP-C is also in the CU-UP.

[0099] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, the radio access network can also be an open radio access network (O-RAN) architecture, in which the CU in the ORAN system can also be referred to as an open CU (O-CU), the DU can also be referred to as an open DU (O-DU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), and the RU can also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0100] For the convenience of understanding the embodiments of the present application, some basic concepts related to the present application are briefly described.

[0101] 1. Time domain resource: a resource unit in the time domain, which can be a symbol, a slot, a mini-slot, a sub-frame, a frame, etc. The representation of the time domain resource in this application is not limited in any way.

[0102] 2. Frequency domain resource: a resource unit in the frequency domain, which can be a resource element (RE), a resource block (RB), a channel, a sub-channel, a control channel element, a resource pool, a bandwidth part (BWP), a carrier, a band, etc. The representation of the frequency domain resource in this application is not limited in any way.

[0103] Exemplarily, the carrier in this application can also be referred to as a carrier component (CC), and the carrier and the carrier component can be used interchangeably hereinafter.

[0104] 3. Multi-carrier single cell: One cell contains multiple carriers, that is, a "multi-carrier single cell". As shown in FIG. 2, cell #1 contains multiple uplink carrier components (UL CCs), such as UL CC #1, UL CC #2 and UL CC #3 shown in FIG. 2; and / or, cell #1 contains multiple downlink carrier components (DL CCs), such as DL CC #1 and DL CC #2 shown in FIG. 2.

[0105] 4. Carrier aggregation (CA): The CA technology can aggregate 2-5 CCs together to increase the system transmission bandwidth, and effectively improve the uplink and downlink transmission rate. As shown in FIG. 3, 5 CCs of 20 megahertz (MHz) can be aggregated together to achieve a transmission bandwidth of 100 MHz. The terminal determines the maximum number of carriers that can be simultaneously used for uplink and downlink transmission according to its own capability.

[0106] It should be understood that FIG. 3 is only an exemplary way of indicating CA, and does not constitute any limitation on the protection scope of the present application. The CA technology can support continuous or non-continuous carrier aggregation, which will not be further described herein.

[0107] The above briefly introduces the scenarios to which the communication method provided by the embodiments of the present application can be applied, and introduces the basic concepts that can be involved in the embodiments of the present application, and introduces the carrier aggregation technology and the multi-carrier single cell configuration in the basic concepts.

[0108] Exemplarily, for the carrier aggregation technology, the following problems exist:

[0109] Each cell contains both uplink carriers and downlink carriers, and in general, the number of normal uplink carriers (Normal UL CC) and normal downlink carriers (Normal DL CC) is 1. With the increase of the service demand of the terminal device, more carrier aggregation capabilities need to be supported, which will cause the processing complexity of the physical layer or RRC of the terminal device to increase with the increase of the number of supported carriers, and the system overhead and signaling overhead will gradually increase. The carrier aggregation in this scenario can be understood as the aggregation of carriers in multiple cells, and the configurations of different cells are different, thereby causing the processing complexity of the physical layer or RRC of the terminal device to increase.

[0110] For example, in a multi-cell scenario, a measurement reference signal needs to be configured separately in each carrier, and an independent measurement process needs to be performed, which is relatively complex; for another example, frequent cell activation and deactivation, long cell activation time, more than 40 ms for hot activation, and more than 80 ms for cold activation.

[0111] Exemplarily, for the multi-carrier single cell configuration, there are the following problems:

[0112] Each carrier in a cell is still processed independently, and radio frequency and baseband are still independently configured for each carrier, and hardware resource overhead cannot necessarily be saved. In addition, the multi-carrier single cell configuration fails to obtain a large bandwidth transmission gain, and uplink transmission fails to obtain the maximum gain when the terminal only transmits in a single carrier bandwidth and the single carrier bandwidth is small.

[0113] As can be seen from the above, both the carrier aggregation technology and the multi-carrier single cell configuration have the problem of large resource overhead caused by independent configuration of each carrier. A spectrum resource allocation manner is: on the basis of the above multi-carrier single cell, the frequency domain resource is still configured in the granularity of a carrier, and in an implementation manner, multiple carriers are jointly received through the same radio frequency (RF) link, but each carrier is still independently processed in the baseband.

[0114] Although the spectrum resource allocation manner can receive carriers of adjacent frequency bands through the same RF link in the radio frequency, the baseband processing is still processed independently in the granularity of a carrier in essence, and the baseband resource cannot be further reduced.

[0115] On the other hand, the current frequency domain resource allocation mechanism cannot completely divide resources according to the processing capacity of the terminal device (such as the radio frequency, baseband, and other processing capacities of the terminal device), which can cause the mismatch between the capacity of the terminal device and the actual spectrum resource, for example, the processing capacity of a single baseband of the terminal device can reach the processing amount of processing 100 MHz bandwidth data, but the carrier bandwidth can only be 20 MHz.

[0116] To solve the problems existing in the above spectrum resource allocation technology, the present application provides a communication method to improve the flexibility of frequency domain resource configuration.

[0117] The communication method provided by the embodiments of the present application can be applied to a system communicating through multi-antenna technology, for example, the communication system 100 shown in FIG. 1. The communication system can include at least one network device and at least one terminal device.

[0118] The embodiments shown below do not particularly limit the specific structure of the execution subject of the method provided by the embodiments of the present application, as long as the execution subject can communicate according to the method provided by the embodiments of the present application by running a program in which the code of the method provided by the embodiments of the present application is recorded. For example, the method provided by the embodiments of the present application can be executed by a first communication device. In the case where no specific description is made, the "first communication device" in the present application can refer to the first communication device itself (for example, a terminal device), or can be a component (for example, a processor, a chip, or a chip system, etc.) in the first communication device, or can be a logic module or software capable of realizing all or part of the function of the first communication device. For another example, the method provided by the embodiments of the present application can be executed by a second communication device. In the case where no specific description is made, the "second communication device" in the present application can refer to the second communication device itself (for example, a network device), or can be a component (for example, a processor, a chip, or a chip system, etc.) in the second communication device, or can be a logic module or software capable of realizing all or part of the function of the second communication device.

[0119] FIG. 4 is a schematic flowchart of a communication method provided by the embodiments of the present application, including the following steps:

[0120] S410, the second communication device sends first indication information to the first communication device, and correspondingly, the first communication device receives the first indication information from the second communication device.

[0121] The first indication information is used to indicate the frequency domain location and the frequency domain size of the first frequency domain resource, that is, the first indication information indicates the first frequency domain resource configured for the first communication device.

[0122] Specifically, the first frequency domain resource in the present application includes all or part of each of at least one carrier. Alternatively, the first frequency domain resource includes all or part of each of a plurality of carriers. As an example but not as a limitation, the at least one carrier included in the first frequency domain resource in the present application can be a carrier in the same cell. For example, the at least one carrier belongs to a cell served by the second communication device. It can be understood that the embodiments of the present application can be applied to the above-mentioned multi-carrier single-cell scenario, for example, the at least one carrier included in the first frequency domain resource can be at least one of the UL CC#1, the UL CC#2 and the UL CC#3 included in the cell #1 shown in FIG. 2.

[0123] Exemplarily, the first frequency domain resource can also be referred to as a bandwidth group (BWG), a frequency domain resource block, or a frequency domain unit, etc. The name of the first frequency domain resource in the present application is not limited in any way, and the frequency domain resource including all or part of each of the at least one carrier can be referred to as the first frequency domain resource.

[0124] The first frequency domain resource includes all or part of each of the at least one carrier, and can be understood as including all or part of each of N carriers, where N is a positive integer. For example, the first frequency domain resource includes all or part of one carrier, or includes all or part of each of two or more carriers.

[0125] By way of example and not limitation, the first indication information indicates the frequency domain location and the frequency domain size of the first frequency domain resource in the present application, including but not limited to the following possible implementation manners:

[0126] As a possible implementation manner, the first indication information indicates the frequency domain start location of the first frequency domain resource and the bandwidth size of the first frequency domain resource.

[0127] In this implementation manner, the first indication information indicating the frequency domain start location of the first frequency domain resource can indicate the frequency domain start location of the first frequency domain resource or indicate the offset of the frequency domain start location of the first frequency domain resource relative to a frequency domain reference location. The frequency domain reference location can be the boundary of a carrier or a frequency band; or the center position of a carrier or a frequency band; or a predefined frequency domain location, for example, Point A.

[0128] For example, if the first frequency domain resource includes carriers in multiple different frequency bands, and the carriers in the multiple different frequency bands are uniformly sorted, the first indication information can indicate the start location and the continuous bandwidth length of the first frequency domain resource in the form of a resource indication value (RIV). As shown in (a) of FIG. 5, the first frequency domain resource includes carriers in frequency band #1 and frequency band #2, and the carriers in frequency band #1 and frequency band #2 are uniformly sorted. As shown in (a) of FIG. 5, the first frequency domain resource includes carrier #1 in frequency band #1, carrier #2 and carrier #3 in frequency band #2.

[0129] For example, if the first frequency domain resource contains multiple carriers in different frequency bands, and the multiple carriers in different frequency bands are sorted respectively, the first indication information can indicate the starting position and the bandwidth length of the first frequency domain resource by indicating the index of the starting carrier corresponding to the frequency domain starting position of the first frequency domain resource, the first offset of the frequency domain starting position of the first frequency domain resource relative to the starting carrier, the index of the terminal carrier corresponding to the frequency domain starting position of the first frequency domain resource, and the second offset of the frequency domain terminal position of the first frequency domain resource relative to the terminal carrier. As shown in (b) of FIG. 5, the first frequency domain resource includes carriers in frequency band #1 and frequency band #2, and the carriers in frequency band #1 and frequency band #2 are independently sorted in the frequency band. As shown in (b) of FIG. 5, the first frequency domain resource includes carrier #1 in frequency band #1, carrier #1 in frequency band #2, the first indication information can indicate carrier #1 in frequency band #1, the first offset of the frequency domain starting position of the first frequency domain resource relative to the starting RB of carrier #1, carrier #2 in frequency band #2, and the second offset of the terminal starting position of the first frequency domain resource relative to the starting RB of carrier #2.

[0130] As another possible implementation, the first indication information indicates the frequency domain starting position of the first frequency domain resource and the frequency domain terminal position of the first frequency domain resource.

[0131] In this implementation, the first indication information indicating the frequency domain starting position of the first frequency domain resource can indicate the absolute frequency domain starting position of the first frequency domain resource or the offset of the frequency domain starting position of the first frequency domain resource relative to a frequency domain reference position, and the first indication information indicating the frequency domain terminal position of the first frequency domain resource can indicate the absolute frequency domain terminal position of the first frequency domain resource or the offset of the frequency domain terminal position of the first frequency domain resource relative to a frequency domain reference position.

[0132] As another possible implementation, the first indication information indicates the center frequency position of the first frequency domain resource and the bandwidth size of the first frequency domain resource.

[0133] In this implementation, the first indication information indicating the center frequency position of the first frequency domain resource can indicate the center frequency position of the first frequency domain resource or the offset of the center frequency position of the first frequency domain resource relative to a frequency domain reference position. The frequency domain reference position can be the boundary of a carrier or a frequency band, or the center position of a carrier or a frequency band, or a predefined frequency domain position, for example, Point A.

[0134] As another possible implementation, the first indication information indicates at least one carrier contained in the first frequency domain resource.

[0135] In this implementation, the first indication information indicates at least one carrier included in the first frequency domain resource, which can be an identifier (e.g., an index) of each carrier in the at least one carrier.

[0136] For ease of understanding, the manner of indicating the first frequency domain resource by the first indication information is briefly introduced in combination with FIG. 6.

[0137] As shown in FIG. 6, the first indication information can indicate the first frequency domain resource by indicating a frequency domain start position and a bandwidth size of the first frequency domain resource (e.g., the first indication information indicates f1 and the bandwidth Δf shown in FIG. 6); or the first indication information can indicate the first frequency domain resource by indicating a frequency domain start position and a frequency domain end position of the first frequency domain resource (e.g., the first indication information indicates f1 and f2 shown in FIG. 6); or the first indication information can indicate the first frequency domain resource by indicating a center frequency position and a bandwidth size of the first frequency domain resource (e.g., the first indication information indicates f3 and Δf shown in FIG. 6); or the first indication information indicates at least one carrier included in the first frequency domain resource, for example, the first indication information indicates an index and / or a frequency band index of a carrier included in the first frequency domain resource, e.g., the first indication information indicates carrier #1, carrier #2 and carrier #3 shown in FIG. 6.

[0138] It should be understood that the above-mentioned several manners of indicating the first frequency domain resource are only examples and do not limit the protection scope of the present application, and the first indication information can also be indicated by other manners to achieve the purpose of indicating the first frequency domain resource, which will not be illustrated one by one here. In the present application, the first indication information can indicate the frequency domain position and the frequency domain size of the first frequency domain resource, and the indicating manner is not limited.

[0139] For example, in this embodiment, the configuration manner of the first frequency domain resource can be: being configured on continuous carriers in a same frequency band, being configured on non-continuous carriers in the same frequency band, being configured on adjacent carriers in adjacent frequency bands, or being configured on different carriers in different frequency bands.

[0140] The first frequency domain resource being configured on continuous carriers or non-continuous carriers in the same frequency band can be understood as: the first frequency domain resource includes all or part of carriers in a frequency band.

[0141] For example, the first frequency domain resource includes a plurality of carriers, the plurality of carriers include a first carrier and a second carrier, and the first carrier and the second carrier satisfy at least one of the following conditions: the first carrier and the second carrier are two continuous or non-continuous carriers in a first frequency band; or

[0142] The first carrier is located in a first frequency band, the second carrier is located in a second frequency band, the first frequency band and the second frequency band are continuous in a frequency domain, and the first carrier and the second carrier are continuous in the frequency domain; or

[0143] The first carrier is located in a first frequency band, the second carrier is located in a second frequency band, and the first carrier and the second carrier are discontinuous in a frequency domain.

[0144] For ease of understanding, the possible configuration modes of the first frequency domain resource in this embodiment are described in detail in combination with (a) to (d) in FIG. 7.

[0145] As shown in (a) of FIG. 7, the carriers included in the first frequency domain resource can be a plurality of carriers that are continuous in the same frequency band, such as the carrier #1, the carrier #2, and the carrier #3 in the frequency band #1 shown in (a) of FIG. 7, which are included in the first frequency domain resource. The guard band (GB) can be a guard band between different carriers.

[0146] As shown in (b) of FIG. 7, the carriers included in the first frequency domain resource can be a plurality of carriers that are discontinuous in the same frequency band, such as the carrier #1, the carrier #2, and the carrier #4 in the frequency band #1 shown in (b) of FIG. 7, which are included in the first frequency domain resource.

[0147] As shown in (c) of FIG. 7, the carriers included in the first frequency domain resource can be a plurality of carriers that are adjacent in adjacent frequency bands, such as the carrier #2 in the frequency band #1 and the carrier #1 in the frequency band #2 shown in (c) of FIG. 7, which are included in the first frequency domain resource.

[0148] As shown in (d) of FIG. 7, the carriers included in the first frequency domain resource can be a plurality of carriers in different frequency bands, such as the carrier #1 in the frequency band #1 and the carrier #1 in the frequency band #2 shown in (d) of FIG. 7, which are included in the first frequency domain resource.

[0149] The above (a) to (d) of FIG. 7 are only exemplary to indicate the configuration mode of the first frequency domain resource in this embodiment, and do not constitute any limitation on the protection scope of the present application. For example, the number of carriers included in the first frequency domain resource can be two or more than two; for another example, the carriers included in the first frequency domain resource can be other possible forms, which are not illustrated one by one here.

[0150] Optionally, before the second communication device configures the first communication device with the first frequency domain resource described above, the second communication device can learn the frequency bands that can be allocated to the first communication device based on the capability of the first communication device. For example, the first communication device reports to the second communication device the single-carrier bandwidth capability that the first communication device can support and the frequency band combination that the first communication device can support, so that the second communication device can perform frequency domain resource allocation based on the capability of the first communication device.

[0151] Additionally, the second communication device can indicate the first communication device to measure some part of the bandwidth through the second indication information, and the method flow shown in FIG. 4 can further include optional steps S411 and S412 based on the measurement result of the first communication device to perform the above-mentioned first frequency domain resource configuration:

[0152] S411, the second communication device sends the second indication information to the first communication device, and correspondingly, the first communication device receives the second indication information from the second communication device.

[0153] The second indication information is used to indicate the first communication device to measure the signal strength corresponding to part or all of the frequency domain interval between adjacent carriers.

[0154] Specifically, after receiving the second indication information, the first communication device can measure the signal strength corresponding to the frequency domain interval between adjacent frequency bands and / or the signal strength corresponding to the frequency domain interval between adjacent carriers.

[0155] For ease of understanding, the frequency domain interval between adjacent frequency bands and the frequency domain interval between adjacent carriers in the present application are briefly introduced in conjunction with FIG. 8.

[0156] As shown in FIG. 8, frequency band #1 and frequency band #2 are adjacent frequency bands, and the frequency domain interval between frequency band #1 and frequency band #2 is frequency domain interval #1, or in other words, the frequency domain interval between carrier #1 and carrier #2 is frequency domain interval #1.

[0157] It should be understood that in the present application, the "adjacent carriers" are not necessarily continuous in the frequency domain, which can refer to the i-th carrier and the i+1-th carrier within a certain frequency domain resource, or can refer to the lowest frequency carrier in the higher frequency band and the highest frequency carrier in the higher frequency band in any two frequency bands.

[0158] S412, the first communication device sends the measurement result to the second communication device, and correspondingly, the second communication device receives the measurement result from the first communication device.

[0159] In this embodiment, the first communication device measures on the corresponding frequency domain resource based on the indication of the second communication device and reports the measurement result. Optionally, the measurement result includes the signal strength corresponding to the frequency domain interval between some adjacent frequency bands or the signal strength corresponding to the frequency domain interval between some adjacent carriers.

[0160] The second communication device can determine the first frequency domain resource based on the measurement result reported by the first communication device.

[0161] Exemplarily, at least one carrier included in the first frequency domain resource can satisfy the following conditional constraints:

[0162] Any two adjacent carriers in the first frequency domain resource determine to satisfy a second condition;

[0163] The second condition includes at least one of the following:

[0164] The second frequency domain interval between any two adjacent carriers is less than a first threshold, a ratio of the second frequency domain interval to a bandwidth of the first frequency domain resource is less than a second threshold, or a signal strength corresponding to the second frequency domain interval is less than a third threshold. Optionally, the signal strength corresponding to the second frequency domain interval can be known based on a measurement result fed back by the first communication device.

[0165] For ease of understanding, the conditions satisfied by the two adjacent carriers in the first frequency domain resource are briefly introduced in conjunction with FIG. 9.

[0166] As shown in FIG. 9, when the frequency domain interval #1 between carrier #1 and carrier #2 is less than the first threshold, carrier #1 and carrier #2 can be configured as carriers included in the first frequency domain resource. For example, B gap ≤ N thre _ BW , where B gap represents the frequency domain interval #1 between carrier #1 and carrier #2, N thre _ BW represents the first threshold.

[0167] As shown in FIG. 9, when the ratio of the frequency domain interval #1 between carrier #1 and carrier #2 to the bandwidth of the first frequency domain resource is less than the second threshold, carrier #1 and carrier #2 can be configured as carriers included in the first frequency domain resource. For example, B gap / B BWG ≤ N thre _ ratio , where B gap represents the frequency domain interval #1 between carrier #1 and carrier #2, N thre _ ratio represents the second threshold, B BWG represents the bandwidth of the first frequency domain resource, and “ / ” represents division or ratio.

[0168] Further, after the first communication device receives the first indication information, the first communication device can know the frequency domain resource capable of information transmission based on the first indication information, and the method flow shown in FIG. 4 further includes:

[0169] S420, the first communication device performs information transmission on the first frequency domain resource.

[0170] Specifically, the first communication device in this embodiment transmits information in the granularity of the first frequency domain resource, which is not limited to information transmission on a single carrier. The information transmission is more flexible, and the transmission performance is improved. Possible transmission modes will be described in detail below, such as the first transmission mode, the second transmission mode, the third transmission mode, or the fourth transmission mode, etc. described below, which are not described here.

[0171] Exemplarily, the information transmitted by the first communication device can be data, signal, or channel information. For example, the data is a transport block; the signal is a signal determined according to a set of configuration parameters, which can be an uplink or downlink reference signal, such as a channel sounding reference signal SRS, or a channel state information reference signal CSI-RS; and the channel is a channel, such as an uplink shared channel PUSCH, or a downlink shared channel PDSCH.

[0172] Exemplarily, the configuration mode of the signal can be:

[0173] configured according to the bandwidth of the first frequency domain resource, as shown in (a) of FIG. 10, a reference signal (RS) is configured within the bandwidth of the first frequency domain resource; or

[0174] configured on a certain carrier of the first frequency domain resource, information transmission on multiple carriers of the first frequency domain resource, and sharing of measurement results determined according to the RS on the carrier, as shown in (b) of FIG. 10, the first frequency domain resource includes carriers #2, #3 and #4 in a certain frequency band (such as the upper half (U6GHz) frequency band on 6GHz), the RS is configured on the carrier #3, and the carriers #2, #3 and #4 share the measurement results determined according to the RS, that is, the parameters of information transmission on the carriers #2, #3 and #4 are determined according to the measurement results of the RS on the carrier #3.

[0175] In this application, the form of the information transmitted by the first communication device is not limited, which can be a transport block (TB), or a reference signal (such as a sounding reference signal (SRS)), etc. In addition, the information transmitted by the first communication device in this application can be received or transmitted information.

[0176] For ease of description, the transmission mode of the first communication device is introduced below by taking the first communication device transmitting or receiving a TB as an example. It should be understood that the transmission mode of the first communication device transmitting other information can refer to the transmission mode of the first communication device transmitting a TB, and the transmission of other types of information will not be described again.

[0177] Specifically, on the first frequency domain resource, the first communication device can transmit or receive 1 TB, which can be within any one carrier in the first frequency domain resource, or on multiple carriers.

[0178] For example, the first communication device transmits 1 TB on the first frequency domain resource, including:

[0179] Transmit the TB on the first frequency domain resource based on at least one of the first transmission mode, the second transmission mode, the third transmission mode, or the fourth transmission mode.

[0180] The first transmission mode is to transmit the TB on the first carrier or the second carrier; the second transmission mode is to transmit the TB on the first carrier and the second carrier respectively, the first part of the TB is mapped to the first carrier, and the second part of the TB is mapped to the second carrier, the first carrier and the second carrier are continuous in the frequency domain; the third transmission mode is to transmit the TB on the first carrier and the second carrier respectively, the first part of the TB is mapped to the first carrier, and the second part of the TB is mapped to the second carrier, the first carrier and the second carrier are discontinuous in the frequency domain; the fourth transmission mode is to transmit the TB on the first carrier and the second carrier, and all or part of the second frequency domain resource respectively, the first carrier and the second carrier are discontinuous in the frequency domain, and the second frequency domain resource is the frequency domain resource between the first carrier and the second carrier.

[0181] For ease of understanding, the manner of the terminal device transmitting or receiving a TB in the first frequency domain resource is described in detail in combination with FIG. 11. As shown in FIG. 11, the first frequency domain resource includes carrier #1 of frequency band #1, and carrier #1 and carrier #2 in frequency band #2.

[0182] The first transmission mode: as shown in FIG. 11, 1 TB can be transmitted on any one carrier in the first frequency domain resource, such as the transmission mode of TB #1 shown in FIG. 11, transmitting or receiving TB #1 on carrier #1 of frequency band #1 in the first frequency domain resource.

[0183] The second transmission mode: as shown in FIG. 11, 1 TB can be transmitted on multiple continuous carriers in the first frequency domain resource, such as the transmission mode of TB #2 shown in FIG. 11, transmitting or receiving TB #2 on carrier #1 and carrier #2 in frequency band #2 in the BWG.

[0184] In the case shown in the second transmission mode, the guard interval in the carrier can also be used to transmit the TB, and the guard band in carrier #1 and carrier #2 in frequency band #2 described above can also be used to transmit TB #2.

[0185] The third transmission manner: as shown in FIG. 11, one TB can be transmitted on multiple non-continuous carriers within the first frequency domain resource, such as the transmission manner of TB#3 shown in FIG. 11, transmitting or receiving TB#3 on carrier#1 of frequency band#1 and carrier#1 of frequency band#2 within the BWG.

[0186] The fourth transmission manner: as shown in FIG. 11, one TB can be transmitted on multiple non-continuous carriers and the gap between multiple frequency bands within the first frequency domain resource, such as the transmission manner of TB#4 shown in FIG. 11, transmitting or receiving TB#4 on carrier#1 of frequency band#1 and carrier#1 of frequency band#2 within the BWG, and the gap between frequency band#1 and frequency band#2.

[0187] In the case shown in the fourth transmission manner, all or part of the guard interval within the carrier can also be used to transmit the TB, such as all of the interval within carrier#1 of frequency band#1 and carrier#1 of frequency band#2 described above can also be used to transmit TB#4. Or, such as part of the interval within carrier#1 of frequency band#1 and carrier#1 of frequency band#2 described above can also be used to transmit TB#5.

[0188] Exemplarily, before the first communication device transmits the TB on the first carrier and / or the second carrier within the first frequency domain resource, the first communication device can determine whether the positions of the first carrier and the second carrier in the frequency domain satisfy a first condition. For example, if the first condition is satisfied, it is determined to transmit information on the first frequency domain resource based on at least one of the first transmission manner, the second transmission manner, the third transmission manner, or the fourth transmission manner described above; if the first condition is not satisfied, it is determined to transmit information on the first frequency domain resource based on at least one of the first transmission manner, the second transmission manner, or the third transmission manner described above.

[0189] Specifically, the first condition includes at least one of the following:

[0190] The first frequency domain interval between the first carrier and the second carrier is less than a first threshold, the ratio of the first frequency domain interval to the bandwidth of the first frequency domain resource is less than a second threshold, or the signal strength corresponding to the first frequency domain interval is less than a third threshold.

[0191] As shown in FIG. 9 above, if the first frequency domain resource includes carrier#1 in frequency band#1 and carrier#1 in frequency band#2 in FIG. 9. When the frequency domain interval between carrier#1 in frequency band#1 and carrier#1 in frequency band#2 satisfies the first condition described above, the first communication device can transmit the TB on carrier#1 in frequency band#1 and carrier#1 in frequency band#2, and the frequency domain interval between carrier#1 in frequency band#1 and carrier#1 in frequency band#2.

[0192] In addition, it should be noted that, according to the current agreement, the terminal device receives and blindly detects the physical downlink control channel (PDCCH) in the configured control resource set (CORESET). That is, for each carrier, the access network device configures a time-frequency resource for the terminal device to blindly detect the PDCCH.

[0193] As described above, in the present application, the frequency domain resource with BWG granularity can be configured to improve the flexibility of resource configuration, and the BWG can include at least one carrier. Therefore, for the case where multiple carriers are included in a BWG, the multiple carriers can share the same CORESET. For example, the multiple carriers share the same CORESET with the same configuration parameters. In a BWG, the terminal device performs PDCCH blind detection in the configured CORESET. Alternatively, a BWG includes only one CORESET, which is configured by a set of configuration parameters.

[0194] For example, the PDCCH in the CORESET can be scheduled according to at least one of the first transmission mode, the second transmission mode, the third transmission mode, or the fourth transmission mode; or,

[0195] Alternatively, it can be scheduled according to single DCI (single DCI). The DCI is downlink control information, which is carried in the PDCCH, and multiple PDSCHs (downlink data) are scheduled by one DCI.

[0196] For example, the second communication device in the present application can indicate the control resource corresponding to the first frequency domain resource through the third indication information, and the control resource is used for receiving and detecting the PDCCH, and the PDCCH is used for scheduling or activating information transmission on the at least one carrier. For example, the control resource is a CORESET.

[0197] Alternatively, the first frequency domain resource in the present application includes only one control resource, and the control resource is located in the transmission bandwidth of one or more carriers in the first frequency domain resource. The transmission bandwidth is the bandwidth used for transmission in the channel bandwidth and excluding the guard interval. For example, the channel bandwidth of a single carrier is 100MHz, and for SCS=30kHz, the guard interval is 845kHz*2=1.69MHz, and the transmission bandwidth is 100-1.69=98.31MHz≈273RB.

[0198] The control resource is used to schedule and activate information transmission on all carriers in the first frequency domain resource, and the control resource is configured by a set of configuration parameters. For example, the transmission of information on at least one carrier in the first frequency domain resource is scheduled or activated by a PDCCH, and the terminal device can determine the PDCCH by detecting the control resource transmitted in the first frequency domain resource, which is located in the transmission bandwidth of one or more carriers in the first frequency domain resource and determined by a set of configuration parameters. For the first frequency domain resource, the location of the CORESET can be indicated in the following ways:

[0199] Method one: the third indication information includes two bitmap, that is, the location of the CORESET is indicated by two bitmap.

[0200] For example, the first bitmap indicates which carriers in the at least one carrier included in the first frequency domain resource are configured with CORESET. The second bitmap indicates which RBs or RBGs in the carrier configured with CORESET are configured with CORESET.

[0201] It should be understood that the CORESET resource cannot be configured on the GB. For the first frequency domain resource including part of carrier #1 and the CORESET being configured on the carrier #1, the third indication information needs to indicate the carrier #1 in the case of indicating which carriers are configured with CORESET, for example, by 1 bit to indicate whether the CORESET is configured on a certain carrier, such as the bit corresponding to the carrier taking the value of 1 indicating that the CORESET is configured on the carrier, and taking the value of 0 indicating that the CORESET is not configured on the carrier.

[0202] Exemplarily, if the first frequency domain resource includes 3 carriers, such as carrier #1, carrier #2 and carrier 3, if the CORESET is configured on RB1 to RB3 of carrier #1, according to the indication method shown in method one, the third indication information can include two bitmap, the first bitmap indicates that the CORESET is configured on carrier #1, such as the first bitmap being 100, indicating that the CORESET is configured on carrier #1; the second bitmap indicates the RBs on which the CORESET is configured on carrier #1, such as the second bitmap being 111000…000, indicating that the CORESET is configured on RB1 to RB3 of carrier #1, or indicating that the CORESET is configured on RBG1 to RBG3 of carrier #1.

[0203] Method two: the third indication information includes 1 bitmap, that is, the location of the CORESET is indicated by 1 bitmap.

[0204] The length of the bitmap is N RB,BWGis the number of all RBs in the first frequency domain resource including the GB, N RBG is the number of RBs contained in a RBG. For example, a BWG contains two carriers, carrier #1 and carrier #2, and the bandwidth of a single carrier is 100 MHz. When the subcarrier spacing is 30 kHz, the total bandwidth of the BWG is 200 MHz, N RB,BWG = 550, N RBG = 6, L bitmap = 91, that is, the length of the bitmap is 91 bits. Each bit corresponds to an RB or RBG. When the bit value is 1, it indicates that the RB or RBG is configured with a CORESET. When the bit value is 0, it indicates that the RB or RBG is not configured with a CORESET. For example, when the bitmap is 101100...000, it indicates that RB #1, RB #3 and RB #4, or RBG #1, RBG #3 and RBG #5 in the BWG are configured with a CORESET.

[0205] For ease of understanding, the location of the CORESET indicated by the third indication information is briefly introduced in combination with (a) and (b) in FIG. 12. As shown in (a) in FIG. 12, the CORESET indicated by the third indication information can be configured on a certain carrier in the first frequency domain resource (for example, CORESET1 configured on carrier #3), or the CORESET indicated by the third indication information can be configured on multiple carriers in the first frequency domain resource (for example, CORESET2 configured on carrier #2 and carrier #4).

[0206] In the communication method shown in FIG. 4, the first communication device can know the frequency domain location and the frequency domain size of the first frequency domain resource configured by the second communication device for the first communication device based on the received first indication information, and the first frequency domain resource includes all or part of each carrier in at least one carrier, that is, the frequency domain resource configured by the second communication device for the first communication device can include one or more carriers, and can include part or all of a certain carrier, without limiting the configuration granularity of one carrier, thereby realizing flexible frequency domain resource configuration. And the frequency domain resource configuration process can include part of a certain carrier, thereby more effectively utilizing scattered frequency domain resources and edge frequency domain resources.
