Description

Information transmission method, communication apparatus, and storage medium

[0001] The present application claims priority to the Chinese patent application No. 202410544648.9, filed on April 30, 2024, and entitled "Information transmission method, communication apparatus, and storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to an information transmission method, a communication apparatus, and a storage medium. BACKGROUND

[0003] In the initial access stage, the terminal can be scheduled with at most one initial bandwidth part (BWP), which will limit the capacity of information transmission in the initial stage. For example, the capacity of transmitting other system information (OSI) is small. In order to solve the above problem, the network device can configure multiple initial BWPs in the initial access stage, so that the terminal schedules the multiple initial BWPs in the initial access stage to improve the capacity of transmitting OSI.

[0004] However, in general, the time when the network device transmits the configuration information of the multiple initial BWPs is usually separated from the time when the network device transmits the OSI by multiple transmission time intervals (TTIs), that is, the terminal can receive the OSI from the network device based on the multiple initial BWPs only after a period of time after receiving the configuration information of the multiple initial BWPs, which results in a large delay in transmitting the OSI. SUMMARY

[0005] In order to solve the above technical problem, the embodiments of the present application provide an information transmission method, a communication apparatus, and a storage medium, which can reduce the delay in transmitting OSI.

[0006] In a first aspect, an information transmission method is provided. The method can be executed by a network device, or by a component of the network device, such as a processor, a chip, or a chip system of the network device, or by a logic module or software that can implement all or part of the network device. Hereinafter, the method is taken as an example executed by the network device. The information transmission method comprises: transmitting first information on a first bandwidth part, and transmitting other system information on multiple bandwidth parts respectively, wherein a subcarrier spacing corresponding to the first bandwidth part is greater than a subcarrier spacing corresponding to other bandwidth parts in the multiple bandwidth parts configured for a terminal, and the first information is used to indicate configuration information of the multiple bandwidth parts.

[0007] In the embodiment of the present application, the network device can send first information for indicating configuration information of multiple part bandwidths on the first part bandwidth, and send other system information on the multiple part bandwidths respectively. Since the subcarrier spacing corresponding to the first part bandwidth is larger than the subcarrier spacing corresponding to other part bandwidths in the multiple part bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first part bandwidth for transmitting the first information and the other system information, so that the unit transmission time interval corresponding to the first part bandwidth becomes shorter, so that the time interval between transmitting the above first information and the other system information can be shortened in the case of the same number of transmission time intervals. That is, based on the above scheme, the network device can transmit the other system information on the first part bandwidth as soon as possible, reduce the delay of the other system information sent by the network device on the first part bandwidth, and further reduce the overall delay of the network device sending the other system information on the multiple part bandwidths.

[0008] In combination with the above first aspect, in a possible implementation, the sending the other system information on the multiple part bandwidths respectively includes: sending the other system information on the first part bandwidth based on a first transmission time interval, determining a second transmission time interval for sending the other system information on a second part bandwidth based on the first transmission time interval, a subcarrier spacing corresponding to the first part bandwidth, and a subcarrier spacing corresponding to the second part bandwidth, and sending the other system information on the second part bandwidth based on the second transmission time interval, where the second part bandwidth is a part bandwidth other than the first part bandwidth in the multiple part bandwidths.

[0009] That is, the network device can send the other system information on different part bandwidths based on different transmission time intervals to improve the flexibility of sending the other system information. In addition, there is a relationship between the second transmission time interval corresponding to the second part bandwidth and the first transmission time interval corresponding to the first part bandwidth, so that the terminal can determine the second transmission time interval based on the first transmission time interval and the subcarrier spacing, that is, the network device does not need to additionally indicate the second transmission time interval corresponding to the second part bandwidth, thereby saving signaling overhead.

[0010] In combination with the above first aspect, in a possible implementation, the multiple part bandwidths are also used for transmitting acknowledgement / negative acknowledgement feedback information, and the method provided in the embodiment of the present application further includes: receiving the acknowledgement / negative acknowledgement feedback information on the multiple part bandwidths respectively.

[0011] That is, in the information transmission method provided by the embodiments of the present application, the network device can not only respectively transmit other system information on the multiple partial bandwidths, but also respectively receive acknowledgement / negative acknowledgement feedback information on the multiple partial bandwidths. Since the subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the multiple partial bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first partial bandwidth for transmitting the first information and the acknowledgement / negative acknowledgement feedback information, so that the unit transmission time interval corresponding to the first partial bandwidth becomes shorter, and in the case of the same number of transmission time intervals, the time interval between the transmission of the first information and the acknowledgement / negative acknowledgement feedback information can be shortened. That is, based on the above scheme, the terminal can transmit the acknowledgement / negative acknowledgement feedback information on the first partial bandwidth as soon as possible, reduce the delay of the acknowledgement / negative acknowledgement feedback information transmitted by the terminal on the first partial bandwidth, and further reduce the overall delay of the terminal in transmitting the acknowledgement / negative acknowledgement feedback information on the multiple partial bandwidths.

[0012] In combination with the first aspect, in a possible implementation, the multiple partial bandwidths are also used for transmitting uplink shared signals, and the method provided by the embodiments of the present application further includes: respectively receiving the uplink shared signals on the multiple partial bandwidths.

[0013] That is, in the information transmission method provided by the embodiments of the present application, the network device can not only respectively transmit other system information on the multiple partial bandwidths, but also respectively receive uplink shared signals on the multiple partial bandwidths. Since the subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the multiple partial bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first partial bandwidth for transmitting the first information and the uplink shared signals, so that the unit transmission time interval corresponding to the first partial bandwidth becomes shorter, and in the case of the same number of transmission time intervals, the time interval between the transmission of the first information and the uplink shared signals can be shortened. That is, based on the above scheme, the terminal can transmit the uplink shared signals on the first partial bandwidth as soon as possible, reduce the delay of the uplink shared signals transmitted by the terminal on the first partial bandwidth, and further reduce the overall delay of the terminal in transmitting the uplink shared signals on the multiple partial bandwidths.

[0014] In combination with the first aspect, in a possible implementation, the multiple partial bandwidths are also used for transmitting sounding reference signals, and the method provided by the embodiments of the present application further includes: respectively receiving the sounding reference signals on the multiple partial bandwidths.

[0015] That is, in the information transmission method provided by the embodiments of the present application, the network device can receive the sounding reference signals on the multiple part bandwidths respectively. That is, the network device can receive more sounding reference signals, so that the network device can obtain more comprehensive channel information by measuring the more sounding reference signals, thereby improving the accuracy of channel measurement.

[0016] In combination with the first aspect, in a possible implementation, the receiving the sounding reference signals on the multiple part bandwidths respectively includes: sending second information, and receiving the sounding reference signals on the third part bandwidth, where the second information is used to indicate the third part bandwidth in the multiple part bandwidths.

[0017] That is, in addition to receiving the sounding reference signals on the multiple part bandwidths respectively, the network device can also receive the sounding reference signals on a part bandwidth (i.e., the third part bandwidth) in the multiple part bandwidths. That is, the network device does not need to receive the sounding reference signals on each part bandwidth, thereby reducing the number of times of transmitting the sounding reference signals, and thereby reducing the communication overhead of transmitting the sounding reference signals.

[0018] In combination with the first aspect, in a possible implementation, the receiving the sounding reference signals on the third part bandwidth includes: receiving the sounding reference signals on the third part bandwidth based on a first frequency hopping pattern.

[0019] That is, the network device can also receive the sounding reference signals on the third part bandwidth through frequency hopping transmission, thereby improving the anti-interference of transmitting the sounding reference signals.

[0020] In combination with the first aspect, in a possible implementation, the receiving the sounding reference signals on the multiple part bandwidths respectively includes: receiving the sounding reference signals on the multiple part bandwidths based on a second frequency hopping pattern.

[0021] That is, the network device can also receive the sounding reference signals on the multiple part bandwidths through frequency hopping transmission respectively, thereby improving the anti-interference of transmitting the sounding reference signals.

[0022] In combination with the first aspect, in a possible implementation, the configuration information of the multiple part bandwidths includes at least one of the following: frequency domain resource indication information of the multiple part bandwidths, a subcarrier spacing corresponding to each part bandwidth in the multiple part bandwidths, an indication manner of the multiple part bandwidths, or a frequency domain resource offset.

[0023] That is, the configuration information of the multiple part bandwidths can include parameters of multiple dimensions of the multiple part bandwidths, such as frequency domain resource indication information, subcarrier spacing, indication manner, or frequency domain resource offset, so that the terminal can clearly and simply determine the multiple part bandwidths based on the configuration information of the multiple part bandwidths.

[0024] In combination with the first aspect, in a possible implementation, the indication manner of the multiple part bandwidths includes a resource indication value RIV and / or a bitmap.

[0025] That is, the embodiments of the present application provide two indication manners of indicating the multiple part bandwidths, one indication manner can indicate the multiple part bandwidths by RIV, and the other indication manner can indicate the multiple part bandwidths by bitmap, so that the network device can adaptively determine the indication manner of the multiple part bandwidths, so that the terminal can more clearly and simply determine the multiple part bandwidths.

[0026] In combination with the first aspect, in a possible implementation, in the case where the indication manner of the multiple part bandwidths is RIV, the frequency domain resource indication information of the multiple part bandwidths includes at least one of the following: a frequency domain resource starting position of a first part bandwidth, an active frequency domain resource unit number of each part bandwidth in the multiple part bandwidths, or a configured frequency domain resource unit number of each part bandwidth; wherein the first part bandwidth is a part bandwidth in the multiple part bandwidths whose frequency domain resource position is less than or equal to a first threshold, and a starting frequency domain resource position of a fourth part bandwidth is a terminal frequency domain resource position of a previous part bandwidth of the fourth part bandwidth, and the fourth part bandwidth is a part bandwidth in the multiple part bandwidths other than the first part bandwidth.

[0027] That is, in the case where the indication manner of the multiple part bandwidths is RIV, the frequency domain resource indication information of the multiple part bandwidths does not need to include full information of each part bandwidth, for example, does not need to include a frequency domain resource starting position of each part bandwidth, but only includes a frequency domain resource starting position of the first part bandwidth. Since the starting frequency domain resource position of the fourth part bandwidth is the terminal frequency domain resource position of the previous part bandwidth of the fourth part bandwidth, the terminal can determine the frequency domain resource starting position of each part bandwidth based on the frequency domain resource starting position of the first part bandwidth, thereby saving signaling overhead.

[0028] In combination with the first aspect, in a possible implementation, the configured frequency domain resource unit number of each part bandwidth is the same, or the configured frequency domain resource unit number of each part bandwidth is inversely proportional to the corresponding subcarrier spacing.

[0029] That is, the embodiment of the present application provides two implementation manners of configuring the maximum frequency domain resource of each part bandwidth, one implementation manner is to configure the number of configured frequency domain resource units of each part bandwidth as the same value, so that the terminal can directly know the maximum frequency domain resource of each part bandwidth, and the process of determining the maximum frequency domain resource of each part bandwidth is saved; the other implementation manner is to configure the relationship between other parameters (for example, subcarrier spacing) and the number of configured frequency domain resource units to achieve the purpose of the maximum frequency domain resource of each part bandwidth, so that compared with the fixed value, the flexibility of the configured maximum frequency domain resource of each part bandwidth can be improved.

[0030] In combination with the first aspect, in a possible implementation manner, in the case that the indication manner of the plurality of part bandwidths is bitmap, the frequency domain resource indication information of the plurality of part bandwidths comprises a bitmap corresponding to each part bandwidth in the plurality of part bandwidths.

[0031] That is, in the case that the indication manner of the plurality of part bandwidths is bitmap, the frequency domain resource indication information of the plurality of part bandwidths can comprise a bitmap corresponding to each part bandwidth in the plurality of part bandwidths, so that the terminal can determine the plurality of part bandwidths through the bitmap corresponding to each part bandwidth.

[0032] In combination with the first aspect, in a possible implementation manner, the configuration information of the plurality of part bandwidths further comprises the number of activated part bandwidths in the plurality of part bandwidths except the first part bandwidth, wherein the first part bandwidth is the part bandwidth in the plurality of part bandwidths whose frequency domain resource position is less than or equal to the first threshold.

[0033] That is, in addition to comprising at least one of the frequency domain resource starting position of the first part bandwidth, the number of activated frequency domain resource units of each part bandwidth in the plurality of part bandwidths, or the number of configured frequency domain resource units of each part bandwidth, the configuration information of the plurality of part bandwidths can further comprise the number of activated part bandwidths in the plurality of part bandwidths except the first part bandwidth, so that the network device does not need to reserve a field for each part bandwidth to indicate whether it is activated, thereby saving signaling overhead.

[0034] In combination with the first aspect, in a possible implementation manner, the frequency domain resource offset is determined based on the subcarrier spacing corresponding to any part bandwidth in the plurality of part bandwidths, wherein the frequency domain resource offset comprises a resource unit granularity frequency domain resource offset and / or a resource block granularity frequency domain resource offset.

[0035] That is, the frequency domain resource offset can be not only a resource unit granularity frequency domain resource offset, but also a finer granularity frequency domain resource offset, i.e., a resource block granularity frequency domain resource offset, so that the frequency domain resource offset can be more accurately reflected.

[0084] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction of the related art is first given. The brief introduction is as follows.

[0085] 1. Initial access stage

[0086] The initial access stage includes a cell search and selection stage and a random access (RA) stage. The cell search and selection stage refers to a stage in which a terminal searches for and selects a network serving the terminal. The RA refers to an information interaction mechanism used for a terminal not accessing a network to establish a connection with the network in an existing communication system, and thus the RA stage refers to a stage in which the terminal accesses the network (i.e., the network determined in the cell search and selection stage). That is, in general, after the cell search and selection stage and the RA stage, the terminal can access the network to implement normal communication with the network device.

[0087] As can be known from the foregoing introduction of the RA, the RA refers to an information interaction mechanism used for a terminal not accessing a network to establish a connection with the network in an existing communication system. The RA can be divided into a contention-based RA and a non-contention-based RA. The interaction processes of the two types of RA are described in detail as follows:

[0088] FIG. 1 shows a schematic diagram of an RA interaction process. As shown in FIG. 1, the process of the contention-based RA usually includes the following four steps, each step corresponding to a message, i.e., step 1 corresponds to message 1, step 2 corresponds to message 2, step 3 corresponds to message 3, and step 4 corresponds to message 4, and the messages are used to carry different signaling or information. The non-contention-based RA usually includes the first two steps (i.e., step 1 and step 2) of the four steps.

[0089] Step 1, a terminal sends a message (Msg) 1 to a network device. Correspondingly, the network device receives the Msg 1 from the terminal.

[0090] The Msg 1 can also be referred to as a random access preamble message. The Msg 1 can be carried on a physical random access channel (PRACH).

[0091] Step 2, the network device sends a Msg 2 to the terminal. Correspondingly, the terminal receives the Msg 2 from the network device.

[0092] The Msg 2 can also be referred to as a random access response message. The Msg 2 is a response of the network device to the received Msg 1, and one Msg 2 can respond to multiple Msg 1s.

[0093] For example, the Msg 2 can include at least one of the following: indices (random access preamble identities, RAPIDs) of multiple Msg 1s, an uplink grant, a timing advance, or a temporary cell radio network temporary identity (TC-RNTI). The above is only an example of the Msg 2, and the Msg 2 can also include other information, which is not limited by the embodiments of the application.

[0094] It should be pointed out that after step 2, the terminal can be synchronized with the network device in uplink, so that the terminal and the network device can subsequently exchange information on a preset resource.

[0095] Step 3, the terminal sends a Msg 3 to the network device. Correspondingly, the network device receives the Msg 3 from the terminal.

[0096] The Msg 3 can also be referred to as a scheduleed transmission message. The information included in the Msg 3 is high-layer information, for example, user identification information. In addition, if multiple different terminals use the same Msg 1 for random access, the network device can distinguish the different terminals through the user identification information carried in the Msg 3.

[0097] Step 4, the network device sends a Msg 4 to the terminal. Correspondingly, the terminal receives the Msg 4 from the network device.

[0098] The Msg4 can also be referred to as a contention resolution message. Since the Msg4 is used for contention resolution, the Msg4 usually includes user identification information carried in the Msg3, so that if the terminal detects the user identification information of the terminal in the Msg4, it is considered that the contention random access is successful, and then the subsequent communication interaction process can be continued.

[0099] Optionally, the network device can monitor a physical uplink control channel (PUCCH) within a preset time window, and transmit the Msg4 based on the PUCCH.

[0100] 2. Initial BWP

[0101] In the initial access process, the terminal needs to occupy a part of the dedicated signal bandwidth to send information to the network device or receive information from the network device, which is referred to as an initial BWP. The configuration information of the initial BWP can be informed to the terminal device by the network device. In addition, the initial BWP can usually be determined by the bandwidth occupied by the coreset 0. Specifically, the terminal can determine the bandwidth occupied by the coreset 0 as the initial BWP.

[0102] The initial BWP can include an uplink initial BWP and a downlink initial BWP, wherein the uplink initial BWP refers to an initial BWP used by the terminal to send information or an initial BWP used by the network device to receive information, and the downlink initial BWP refers to an initial BWP used by the network device to send information or an initial BWP used by the terminal to receive information.

[0103] 3. Coreset 0

[0104] The coreset 0 includes a system information block (SIB) 1, which can be used to indicate necessary system messages in the initial access stage, for example, system messages used to indicate the location of the time-frequency domain resources of the OSI. The OSI refers to other system messages transmitted in the initial access stage in addition to the SIB 1 in a broadcast or on-demand request manner, for example, SIB2-SIB20. Usually, the number of bits occupied by the OSI is higher than the number of bits occupied by the SIB 1.

[0105] 4. Activation of initial BWP

[0106] The activated initial BWP refers to an initial BWP actually occupied by the terminal in the initial BWPs configured by the network device for the terminal. For example, it is assumed that the initial BWPs configured by the network device for the terminal include initial BWP1, initial BWP2, and initial BWP3: if the terminal occupies the initial BWP1 to send a message to the network device, the initial BWP1 can be referred to as the activated initial BWP.

[0107] 5. Indication mode of initial BWP

[0108] The indication mode of the initial BWP includes two modes: a resource indicator value (RIV) and a bitmap.

[0109] The RIV is a value, and the value has a corresponding relationship with the number of partial frequency domain resources and / or the starting position of the frequency domain resources. That is, the RIV can indirectly indicate the number of partial frequency domain resources and / or the starting position of the frequency domain resources. Optionally, the RIV can satisfy the following formula 1:

[0110] The RB start is the starting position of the frequency domain resources. The L RBs is the length of the frequency domain resources. is the number of configured frequency domain resource units.

[0111] The bitmap specifically indicates the frequency domain resources of the initial BWP scheduling in all available frequency domain resources, and indicates whether the frequency domain resources are located in the initial BWP by 1 and 0. For example, it is assumed that the available frequency domain resources include resource blocks (RBs) 1, 2, 3, 4, and 5: if the RBs 1, 2, and 5 are the RBs in the initial BWP, the bitmap used to indicate the initial BWP can be 11001.

[0112] The above is a brief introduction to the technical terms related to the present application.

[0113] In the initial access stage, the terminal can be scheduled with at most one initial BWP, which will limit the capacity of the transmission information in the initial stage. For example, the capacity of the OSI transmission is small. At present, the method for improving the transmission information capacity is mainly the CA technology. The existing new radio (NR) protocol stipulates that the CA technology can aggregate multiple CCs, so that the available bandwidth of the terminal is the sum of the bandwidths corresponding to the multiple carriers, which can effectively improve the peak rate of the transmission information.

[0114] In a communication system supporting CA technology, a network device can configure multiple carriers for a terminal based on the capability reported by the terminal, and activate the multiple carriers configured for the terminal, so that the terminal can use multiple carriers.

[0115] The interaction information about carrier configuration between the network device and the terminal needs to be transmitted through RRC signaling in the RRC connected state. That is, the terminal reports the capability, and the network device issues the carrier configuration information, which needs to be performed in the RRC connected state. The establishment of the RRC connected state needs to be completed in steps 3 to 4 of the RA phase, that is, the network device can only transmit the carrier configuration information after the steps 3 to 4 are completed, which makes the network device unable to use the CA technology before step 3, resulting in that the capacity of the transmission information in the initial stage is still limited.

[0116] In order to further improve the capacity of the transmission information in the initial stage, the network device can configure multiple initial BWPs in the initial access stage, so that the terminal schedules the multiple initial BWPs in the initial access stage to improve the capacity of the transmission OSI.

[0117] However, in general, the time when the network device transmits the configuration information of the multiple initial BWPs is usually separated from the time when the network device transmits the OSI by multiple TTIs, that is, after a period of time when the terminal receives the configuration information of the multiple initial BWPs, the terminal can receive the OSI from the network device based on the multiple initial BWPs, which results in a large delay in transmitting the OSI.

[0118] Therefore, the present application provides an information transmission method. The network device can transmit first information for indicating configuration information of multiple part-bandwidths on a first part-bandwidth, and transmit other system information on the multiple part-bandwidths respectively. Since the subcarrier spacing corresponding to the first part-bandwidth is greater than the subcarrier spacing corresponding to other part-bandwidths in the multiple part-bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first part-bandwidth for transmitting the first information and the other system information, so that the unit transmission time interval corresponding to the first part-bandwidth becomes shorter, which makes the time interval between transmitting the first information and the other system information shorter in the case of the same number of transmission time intervals. That is, based on the information transmission method provided by the embodiments of the present application, the network device can transmit the other system information on the first part-bandwidth as soon as possible, reduce the delay of the other system information transmitted by the network device on the first part-bandwidth, and further reduce the overall delay of the network device transmitting the other system information on the multiple part-bandwidths.

[0119] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0130] FIG. 2 shows a possible, non-limiting system diagram. As shown in FIG. 2, the communication system 2000 includes a radio access network (RAN) 200 and a core network (CN) 300. The RAN 200 includes at least one RAN node (e.g., 210a and 210b in FIG. 2, collectively referred to as 210) and at least one terminal (e.g., 220a-220j in FIG. 2, collectively referred to as 220). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 2), etc., can also be included in the RAN 200. The terminal 220 is connected to the RAN node 210 in a wireless manner. The RAN node 210 is connected to the core network 300 in a wireless or wired manner. The core network device in the core network 300 and the RAN node 210 in the RAN 200 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0131] The RAN 200 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolution system (e.g., a 6G mobile communication system). The RAN 200 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 200 can also be a communication system in which two or more of the above systems are integrated.

[0132] The RAN node 210, which can also be referred to as an access network device, a RAN entity, or an access node, etc., forms part of the communication system, and is configured to facilitate wireless access to the communication system for terminals. The RAN nodes 210 in the communication system 2000 can be of the same type or different types. In some scenarios, the roles of the RAN node 210 and the terminal 220 are relative, e.g., the network element 220i in Figure 2 can be a helicopter or a drone, which can be configured to move as a mobile base station, to the terminal 220j accessing the RAN 200 through the network element 220i, the network element 220i is a base station; but to the base station 210a, the network element 220i is a terminal. The RAN nodes 210 and the terminals 220 are sometimes referred to as communication apparatuses, e.g., the network elements 210a and 210b in Figure 2 can be understood as communication apparatuses with base station functionality, and the network elements 220a-220j can be understood as communication apparatuses with terminal functionality

[0133] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (e.g., 210a in Figure 2), a micro base station or an indoor station (e.g., 210b in Figure 2), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in a vehicle to everything (V2X) technology can be a road side unit (RSU).

[0134] In another possible scenario, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node 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 configured, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0135] 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, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU, and RU are taken as examples for description in this application. Any one 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.

[0136] Optionally, the base station in the embodiments of this application can include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, access points, home base stations, TRPs, transmitting points (TPs), mobile switching centers, etc., and the embodiments of this application do not make specific limitations thereto.

[0137] In a possible implementation, in the embodiments of the present application, the network device and the terminal can be both configured with multiple antennas to support massive multiple input multiple output (Massive-MIMO) technology. Further, the network device and the terminal can support both single-user MIMO (SU-MIMO) technology and multi-user MIMO (MU-MIMO) technology. The MU-MIMO technology can be implemented based on space division multiple access (SDMA) technology. Due to the configuration of multiple antennas, the network device and the terminal can also flexibly support Single Input Single Output (SISO) technology, Single Input multiple Output (SIMO) and multiple input single output (MISO) technology to implement various diversity (for example, but not limited to, transmit diversity and receive diversity) and multiplexing technologies, wherein the diversity technology can include, but is not limited to, transmit diversity (TD) technology and receive diversity (RD) technology, and the multiplexing technology can be spatial multiplexing technology.

[0138] In a possible implementation, the network device and the terminal in the embodiments of the present application can also be referred to as communication apparatuses, which can be a general-purpose device or a special-purpose device, and the embodiments of the present application do not make specific limitations thereon.

[0146] The information transmission method provided by the embodiments of the present application will be described below in conjunction with FIG. 4.

[0147] It should be noted that the names of messages, the names of parameters, or the names of information between the network elements in the following embodiments of the present application are only examples, and other names can also be used in other embodiments. The method provided by the embodiments of the present application does not make specific limitations on this. It can be understood that in the embodiments of the present application, each network element can perform part or all of the steps in the embodiments of the present application. These steps or operations are examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, each step can be performed in a different order as presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0148] FIG. 4 is an example of the information transmission method provided by the embodiments of the present application. The method is illustrated by taking the interaction between a terminal and a network device as an example. Of course, the subject performing the terminal actions in the method can also be a device / module in the terminal, such as a chip, a processor, a processing unit, etc. in the terminal; and the subject performing the network device actions in the method can also be a device / module in the network device, such as a chip, a processor, a processing unit, etc. in the network device, which is not limited in the embodiments of the present application. For example, as shown in FIG. 4, the information transmission method includes the following steps:

[0149] S401, the network device sends first information on a first partial bandwidth. Correspondingly, the terminal receives the first information on the first partial bandwidth.

[0150] The subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the plurality of partial bandwidths configured for the terminal. The first information is used to indicate configuration information of the plurality of partial bandwidths.

[0151] Optionally, the partial bandwidth described in the embodiments of the present application can be understood as an initial BWP. Further, the above-mentioned initial BWP can also be understood as an initial downlink BWP, and the initial downlink BWP can include at least one initial uplink BWP. Of course, the above-mentioned is only an example of the above-mentioned partial bandwidth, and the above-mentioned partial bandwidth can also be understood as other bandwidths, or the above-mentioned partial bandwidth can also be referred to as other names in other network architectures, which is not limited in the embodiments of the present application.

[0152] Optionally, the configuration information of the plurality of partial bandwidths can be understood as configuration parameters of the plurality of partial bandwidths. The configuration parameters of the plurality of partial bandwidths can have the same function as the configuration information of the plurality of partial bandwidths, for example, the configuration parameters of the plurality of partial bandwidths can include parameters or information related to frequency domain resources and / or time domain resources. Of course, the above is only an exemplary description of the configuration information of the plurality of partial bandwidths, and the configuration information of the plurality of partial bandwidths can also be understood as other information, or the configuration information of the plurality of partial bandwidths can also be referred to as other names in other network architectures, and the embodiments of the present application do not make any limitation in this regard.

[0153] S402, the network device respectively transmits other system information on the plurality of partial bandwidths. Correspondingly, the terminal respectively receives other system information on the plurality of partial bandwidths.

[0154] Optionally, the other system information can be understood as OSI. Of course, the above is only an exemplary description of the other system information, and the other system information can also be understood as other information, or the other system information can also be referred to as other names in other network architectures, and the embodiments of the present application do not make any limitation in this regard.

[0155] In the information transmission method provided by the embodiments of the present application, the network device can transmit first information for indicating configuration information of a plurality of partial bandwidths on a first partial bandwidth, and respectively transmit other system information on the plurality of partial bandwidths. Since the subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the plurality of partial bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first partial bandwidth for transmitting the first information and the other system information, so that the unit transmission time interval corresponding to the first partial bandwidth becomes shorter, so that in the case of the same number of transmission time intervals, the time interval between transmitting the first information and the other system information can be shortened. That is, based on the above scheme, the network device can transmit the other system information on the first partial bandwidth as soon as possible, reduce the time delay of the other system information transmitted by the network device on the first partial bandwidth, and further reduce the overall time delay of the network device transmitting the other system information on the plurality of partial bandwidths.

[0156] For example, FIG. 5 shows an example diagram of the relationship between subcarrier spacing and transmission time interval. As shown in FIG. 5, it is assumed that the subcarrier spacing corresponding to the partial bandwidth 1 is 30 kHz, and the subcarrier spacing corresponding to the partial bandwidth 2 is 40 kHz; the unit transmission time interval corresponding to the partial bandwidth 1 is 40 ms, and the unit transmission time interval corresponding to the partial bandwidth 2 is 20 ms. Therefore, the subcarrier spacing corresponding to the partial bandwidth 1 is smaller than the subcarrier spacing corresponding to the partial bandwidth 2, and the unit transmission time interval corresponding to the partial bandwidth 1 is larger than the unit transmission time interval corresponding to the partial bandwidth 2.

[0157] If the first partial bandwidth is the partial bandwidth 1, the network device transmits the first information based on the transmission time interval 1 on the partial bandwidth 1, and transmits the other system information based on the transmission time interval 2 on the partial bandwidth 1, so that the time interval between transmitting the first information and the other system information is the unit transmission time interval corresponding to two partial bandwidth 1 (i.e., 80 ms).

[0158] If the first partial bandwidth is the partial bandwidth 2, the network device transmits the first information based on the transmission time interval 1 on the partial bandwidth 2, and transmits the other system information based on the transmission time interval 2 on the partial bandwidth 2, so that the time interval between transmitting the first information and the other system information is the unit transmission time interval corresponding to two partial bandwidth 2 (i.e., 40 ms).

[0159] As can be seen from the above example, in the case of the same number of transmission time intervals, if the subcarrier spacing corresponding to the first partial bandwidth is larger, the time interval between transmitting the first information and the other system information on the first partial bandwidth is shorter, so that the network device can transmit the other system information on the first partial bandwidth as soon as possible, thereby reducing the time delay of the other system information transmitted by the network device on the first partial bandwidth, and further reducing the overall time delay of the network device transmitting the other system information on multiple partial bandwidths.

[0160] The subcarrier spacing corresponding to the first partial bandwidth is described in detail as follows.

[0161] In a possible implementation, the subcarrier spacing corresponding to the first part bandwidth can be greater than the subcarrier spacing corresponding to each of the other part bandwidths in the plurality of part bandwidths configured for the terminal. That is, the first part bandwidth is the part bandwidth with the largest subcarrier spacing in the plurality of part bandwidths. For example, assuming that the plurality of part bandwidths include part bandwidth 1, part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, and the subcarrier spacing corresponding to part bandwidth 1 is 30 kHz, the subcarrier spacing corresponding to part bandwidth 2 is 40 kHz, the subcarrier spacing corresponding to part bandwidth 3 is 50 kHz, the subcarrier spacing corresponding to part bandwidth 4 is 60 kHz, and the subcarrier spacing corresponding to part bandwidth 5 is 70 kHz, the network device can determine part bandwidth 5 as the first part bandwidth.

[0162] In another possible implementation, the subcarrier spacing corresponding to the first part bandwidth can be greater than the subcarrier spacing corresponding to one of the other part bandwidths. The one of the other part bandwidths is the part bandwidth with the smallest subcarrier spacing. For example, assuming that the plurality of part bandwidths include part bandwidth 1, part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, and the subcarrier spacing corresponding to part bandwidth 1 is 30 kHz, the subcarrier spacing corresponding to part bandwidth 2 is 40 kHz, the subcarrier spacing corresponding to part bandwidth 3 is 50 kHz, the subcarrier spacing corresponding to part bandwidth 4 is 60 kHz, and the subcarrier spacing corresponding to part bandwidth 5 is 70 kHz, the network device can determine part bandwidth 2 and / or part bandwidth 3 and / or part bandwidth 4 and / or part bandwidth 5 as the first part bandwidth.

[0163] In addition, the first part bandwidth can include some or all of the plurality of part bandwidths. That is, the number of part bandwidths included in the first part bandwidth is not limited in the embodiments of the present application.

[0164] In another possible implementation, the subcarrier spacing corresponding to the first part bandwidth can be greater than the subcarrier spacing corresponding to one of the other part bandwidths. The one of the other part bandwidths is any part bandwidth. For example, assuming that the plurality of part bandwidths include part bandwidth 1, part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, and the subcarrier spacing corresponding to part bandwidth 1 is 30 kHz, the subcarrier spacing corresponding to part bandwidth 2 is 40 kHz, the subcarrier spacing corresponding to part bandwidth 3 is 50 kHz, the subcarrier spacing corresponding to part bandwidth 4 is 60 kHz, and the subcarrier spacing corresponding to part bandwidth 5 is 70 kHz, if the one of the other part bandwidths is part bandwidth 3, the network device can determine part bandwidth 4 and / or part bandwidth 5 as the first part bandwidth.

[0165] Of course, the above is only an exemplary description of the subcarrier spacing corresponding to the first part bandwidth, and other relationships can exist between the subcarrier spacing corresponding to the first part bandwidth and the subcarrier spacing corresponding to other part bandwidths. The embodiments of the present application do not make any limitation in this regard.

[0166] The configuration information of the plurality of part bandwidths indicated by the first information is described in detail below.

[0167] Optionally, the configuration information of the plurality of part bandwidths includes at least one of the following: frequency domain resource indication information of the plurality of part bandwidths, subcarrier spacing corresponding to each part bandwidth of the plurality of part bandwidths, indication manner of the plurality of part bandwidths, or frequency domain resource offset.

[0168] The frequency domain resource indication information of the plurality of part bandwidths is mainly used to indicate the number of resource blocks included in each part bandwidth of the plurality of part bandwidths and / or the starting position of the resource blocks included in each part bandwidth. However, the frequency domain resource indication information of the plurality of part bandwidths can also be different in different cases.

[0169] That is, the configuration information of the plurality of part bandwidths can include parameters of multiple dimensions of the plurality of part bandwidths, such as the frequency domain resource indication information, the subcarrier spacing, the indication manner, or the frequency domain resource offset, so that the terminal can clearly and simply determine the plurality of part bandwidths based on the configuration information of the plurality of part bandwidths.

[0170] Further, for the frequency domain resource indication information of the plurality of part bandwidths, the frequency domain resource indication information of each part bandwidth included in the frequency domain resource indication information of the plurality of part bandwidths can be independent of each other. That is, the terminal can directly know the frequency domain resource corresponding to the part bandwidth based on the frequency domain resource indication information of the part bandwidth.

[0171] Alternatively, the frequency domain resource indication information of each part bandwidth included in the frequency domain resource indication information of the plurality of part bandwidths can be dependent on each other. Specifically, the frequency domain resource indication information of each part bandwidth can be dependent on the frequency domain resource position of the previous part bandwidth of the part bandwidth to indicate. That is, the frequency domain resource indication information of each part bandwidth can indicate the relationship between the frequency domain resource of the part bandwidth and the frequency domain resource of the previous part bandwidth, so that the terminal can determine the frequency domain resource corresponding to the part bandwidth based on the frequency domain resource indication information of the part bandwidth and the previous part bandwidth.

[0172] In addition, the first part bandwidth does not need to depend on the frequency domain resource position of other part bandwidths for indication, that is, the frequency domain resource indication information of the first part bandwidth can be independent, and the frequency domain resource indication information about the first part bandwidth can be understood by referring to the description of the corresponding position above, which will not be repeated here.

[0173] Of course, the above is only an exemplary description of the frequency domain resource indication information of the plurality of part bandwidths, and the frequency domain resource indication information of the plurality of part bandwidths can also include other information or be represented in other forms, which is not limited by the embodiments of the present application.

[0174] Further, for the subcarrier spacing corresponding to each part bandwidth of the plurality of part bandwidths, the subcarrier spacing corresponding to each part bandwidth of the plurality of part bandwidths can be used to determine the number of frequency domain resource units included in the part bandwidth, and can be carried in the configuration information of the plurality of part bandwidths. In addition, if the subcarrier spacing corresponding to each part bandwidth of the plurality of part bandwidths is not included in the configuration information of the plurality of part bandwidths, the subcarrier spacing corresponding to each part bandwidth of the plurality of part bandwidths is defaulted to be a preset value.

[0175] In some possible implementation manners, the subcarrier spacing corresponding to the plurality of part bandwidths can be the same. For example, assuming that the plurality of part bandwidths include part bandwidth 1, part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, the subcarrier spacing corresponding to part bandwidths 1 to 5 can all be 30 kHz.

[0176] In other possible implementation manners, the subcarrier spacing corresponding to the plurality of part bandwidths can also be different. For example, assuming that the plurality of part bandwidths include part bandwidth 1, part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, the subcarrier spacing corresponding to part bandwidth 1 can be 30 kHz, the subcarrier spacing corresponding to part bandwidth 2 can be 40 kHz, the subcarrier spacing corresponding to part bandwidth 3 can be 50 kHz, the subcarrier spacing corresponding to part bandwidth 4 can be 60 kHz, and the subcarrier spacing corresponding to part bandwidth 5 can be 70 kHz.

[0177] In addition, different subcarrier spacings can be configured for different partial bandwidths, so that the network device can determine to send information to the terminal with appropriate latency according to the scenario in which the terminal is located. For example, FIG. 6 shows an example diagram of configuring different subcarrier spacings for different scenarios. As shown in FIG. 6, it is assumed that the multiple partial bandwidths include partial bandwidth 1, partial bandwidth 2, partial bandwidth 3, partial bandwidth 4, and partial bandwidth 5, partial bandwidth 1 corresponds to subcarrier spacing 1, partial bandwidth 2 corresponds to subcarrier spacing 2, partial bandwidth 3 corresponds to subcarrier spacing 3, partial bandwidth 4 corresponds to subcarrier spacing 4, and partial bandwidth 5 corresponds to subcarrier spacing 5, and the above subcarrier spacings 1 to 5 decrease in turn. If the terminal is in an indoor scenario, the network device can send information on the partial bandwidth corresponding to a larger subcarrier spacing, for example, on the partial bandwidth corresponding to subcarrier spacing 1, to reduce the information transmission latency, and if the terminal is in an outdoor scenario, the network device can send information on the partial bandwidth corresponding to a smaller subcarrier spacing, for example, on the partial bandwidth corresponding to subcarrier spacing 5, to improve the anti-interference degree of information transmission.

[0178] Further, for the above frequency domain resource offset, optionally, the frequency domain resource offset is determined based on the subcarrier spacing corresponding to any one of the multiple partial bandwidths. The frequency domain resource offset includes a resource unit granularity frequency domain resource offset and / or a resource block granularity frequency domain resource offset.

[0179] That is, the frequency domain resource offset can not only be a resource unit granularity frequency domain resource offset, but also a finer granularity frequency domain resource offset, i.e., a resource block granularity frequency domain resource offset, which can more accurately reflect the frequency domain resource offset.

[0180] Alternatively, the frequency domain resource offset is determined based on the subcarrier spacing corresponding to a specific partial bandwidth of the multiple partial bandwidths, wherein the specific partial bandwidth can be a partial bandwidth with the largest frequency domain resource position in the multiple partial bandwidths.

[0181] It can be understood that if the frequency domain resource offset is a resource block granularity frequency domain resource offset and the frequency domain resource offset is less than one resource unit, the terminal reduces 1 from the original starting frequency domain resource position to determine the real starting frequency domain resource position of the partial bandwidth. In addition, the terminal can additionally indicate the starting frequency domain resource position of the subcarrier granularity to achieve more fine-grained indication of the starting frequency domain resource position.

[0182] For example, the frequency domain resource block described in the embodiments of the present application can be an RB. Of course, the above is only an example of the above frequency domain resource block, and the above frequency domain resource block can also be other frequency domain resources, which are not limited by the embodiments of the present application.

[0183] Further, for the indication manner of the plurality of partial bandwidths, the indication manner of the plurality of partial bandwidths can be important for the terminal to determine the plurality of partial bandwidths, and can be carried in the configuration information of the plurality of partial bandwidths. In addition, if the indication manner of the plurality of partial bandwidths is not included in the configuration information of the plurality of partial bandwidths, the indication manner of the plurality of partial bandwidths is a preset indication manner by default.

[0184] Further, optionally, the indication manner of the plurality of partial bandwidths includes RIV and / or bitmap. Of course, the above is only an exemplary description of the indication manner of the plurality of partial bandwidths, and the indication manner of the plurality of partial bandwidths can also include other manners, and the embodiments of the present application do not make any limitation in this regard.

[0185] In view of the above description of the indication manner of the plurality of partial bandwidths, the indication manner of the plurality of partial bandwidths can be divided into the following three cases: case 1 is that the indication manner of the plurality of partial bandwidths is RIV; case 2 is that the indication manner of the plurality of partial bandwidths is bitmap; and case 3 is that the indication manner of the plurality of partial bandwidths includes RIV and bitmap. That is, the embodiments of the present application provide two indication manners for indicating the plurality of partial bandwidths, one indication manner can indicate the plurality of partial bandwidths through RIV, and the other indication manner can indicate the plurality of partial bandwidths through bitmap, so that the network device can adaptively determine the indication manner of the plurality of partial bandwidths, so that the terminal can more clearly and simply determine the plurality of partial bandwidths. The above two cases are described in detail as follows.

[0186] Case 1 is that the indication manner of the plurality of partial bandwidths is RIV.

[0187] In the case of the indication manner of the plurality of partial bandwidths being RIV (i.e., case 1), the frequency domain resource indication information of the plurality of partial bandwidths includes at least one of the following: a starting position of a frequency domain resource of a first partial bandwidth, an activated frequency domain resource unit number of each partial bandwidth in the plurality of partial bandwidths, or a configured frequency domain resource unit number of each partial bandwidth.

[0188] The first partial bandwidth is a partial bandwidth in the plurality of partial bandwidths whose frequency domain resource position is less than or equal to a first threshold. The starting frequency domain resource position of the fourth partial bandwidth is the ending frequency domain resource position of the previous partial bandwidth of the fourth partial bandwidth. The fourth partial bandwidth is a partial bandwidth in the plurality of partial bandwidths except the first partial bandwidth.

[0189] Optionally, the activated frequency domain resource unit quantity can be understood as an actually occupied frequency domain resource quantity, and the configured frequency domain resource unit quantity can be understood as a maximum value of a usable frequency domain resource quantity. Of course, the above is only an exemplary description of the activated frequency domain resource unit quantity and the configured frequency domain resource unit quantity, and other understandings of the activated frequency domain resource unit quantity or the configured frequency domain resource unit quantity can exist, and the embodiments of the present application do not make any limitation thereto.

[0190] That is, in the case of the indication manner of the multiple part bandwidths being RIV, the frequency domain resource indication information of the multiple part bandwidths does not need to include full quantity information of each part bandwidth, for example, does not need to include the frequency domain resource starting position of each part bandwidth, but only includes the frequency domain resource starting position of the first part bandwidth. Since the starting frequency domain resource position of the fourth part bandwidth is the terminal frequency domain resource position of the previous part bandwidth of the fourth part bandwidth, the terminal can determine the frequency domain resource starting position of each part bandwidth based on the frequency domain resource starting position of the first part bandwidth, thereby saving signaling overhead.

[0191] It can be understood that the specific implementation process of the terminal determining the part bandwidth according to the frequency domain resource indication information of the multiple part bandwidths (that is, at least one of the frequency domain resource starting position of the first part bandwidth, the activated frequency domain resource unit quantity of each part bandwidth in the multiple part bandwidths, or the configured frequency domain resource unit quantity of each part bandwidth) can refer to the implementation process of determining "RIV" described above. That is, the terminal can calculate the RIV of the first part bandwidth according to the above formula 1, and take the terminal frequency domain resource position of the first part bandwidth as the starting frequency domain resource position of the part bandwidth ranked second, and calculate the RIV of the part bandwidth according to the above formula 1. The terminal can sequentially determine the RIV of each part bandwidth based on the above method. Other descriptions of "RIV" can be understood with reference to the description of the corresponding position described above, which will not be described here.

[0192] For example, FIG. 7 shows an example diagram of multiple part bandwidths. As shown in FIG. 7, assuming that the multiple part bandwidths include part bandwidth 1 and part bandwidth 2, the terminal device can determine the RIV of part bandwidth 1 as RIV1 based on the above method, and determine the RIV of part bandwidth 2 as RIV2 based on the above method.

[0193] As can be known from the foregoing description related to the "fourth partial bandwidth", the starting frequency domain resource position of the fourth partial bandwidth is the terminal frequency domain resource position of the preceding partial bandwidth of the fourth partial bandwidth. That is, the plurality of partial bandwidths recorded in the embodiments of the present application can be a plurality of continuous partial bandwidths. For example, assuming that the plurality of partial bandwidths include partial bandwidth 1, partial bandwidth 2, partial bandwidth 3, partial bandwidth 4, and partial bandwidth 5, the partial bandwidth 1 can include frequency domain resource units 0-9, the partial bandwidth 2 can include frequency domain resource units 9-19, the partial bandwidth 3 can include frequency domain resource units 19-29, the partial bandwidth 4 can include frequency domain resource units 29-39, and the partial bandwidth 5 can include frequency domain resource units 39-45.

[0194] Of course, the above is only an exemplary description of the plurality of partial bandwidths recorded in the embodiments of the present application, and the plurality of partial bandwidths recorded in the embodiments of the present application can also be a plurality of discontinuous partial bandwidths, and the embodiments of the present application do not make any limitation on this.

[0195] However, for the configuration of the number of frequency domain resource units of the plurality of partial bandwidths, in some possible implementation manners, the number of frequency domain resource units of each partial bandwidth is the same. For example, assuming that the plurality of partial bandwidths include partial bandwidth 1, partial bandwidth 2, partial bandwidth 3, partial bandwidth 4, and partial bandwidth 5, the number of frequency domain resource units of the partial bandwidths 1-5 can be 275;

[0196] Alternatively, for the configuration of the number of frequency domain resource units of the plurality of partial bandwidths, in some possible implementation manners, the number of frequency domain resource units of each partial bandwidth is inversely proportional to the corresponding subcarrier spacing. For example, assuming that the plurality of partial bandwidths include partial bandwidth 1 and partial bandwidth 2, the subcarrier spacing corresponding to the partial bandwidth 1 can be 30 kHz, the number of frequency domain resource units of the partial bandwidth 1 can be 1100, the subcarrier spacing corresponding to the partial bandwidth 2 can be 120 kHz, and the number of frequency domain resource units of the partial bandwidth 1 can be 275.

[0197] That is, the embodiments of the present application provide two implementation manners for configuring the maximum frequency domain resource of each partial bandwidth. One implementation manner is to configure the number of frequency domain resource units of each partial bandwidth as the same value, so that the terminal can directly know the maximum frequency domain resource of each partial bandwidth, and the process of determining the maximum frequency domain resource of each partial bandwidth is saved. The other implementation manner is to configure the relationship between other parameters (for example, the subcarrier spacing) and the number of frequency domain resource units to achieve the purpose of the maximum frequency domain resource of each partial bandwidth, so that compared with the fixed value, the flexibility of the configured maximum frequency domain resource of each partial bandwidth can be improved.

[0198] Of course, the above is only an exemplary description of the number of configured frequency domain resource units of each part bandwidth, and the number of configured frequency domain resource units of each part bandwidth can also be related to other indicators, and the embodiments of the present application do not make any limitation in this regard.

[0199] For example, the frequency domain resource unit described in the embodiments of the present application can be an RE. Of course, the above is only an exemplary description of the frequency domain resource unit, and the frequency domain resource unit can also be other frequency domain resources, and the embodiments of the present application do not make any limitation in this regard.

[0200] The first threshold described in the embodiments of the present application can be fixed, and can also be dynamically changed. For example, the network device sets the minimum position of the starting frequency domain resource unit in the above plurality of part bandwidths as the first threshold, and the embodiments of the present application do not make any limitation in this regard.

[0201] Case 2 is that the indication manner of the plurality of part bandwidths is bitmap.

[0202] In the case that the indication manner of the plurality of part bandwidths is bitmap (i.e. case 2), the frequency domain resource indication information of the plurality of part bandwidths includes a bitmap corresponding to each part bandwidth in the plurality of part bandwidths. The bitmap related to the embodiments of the present application can be understood with reference to the description of the above "bitmap", which will not be repeated here.

[0203] For example, FIG. 8 shows an example of a plurality of part bandwidths. As shown in FIG. 8, assuming that the plurality of part bandwidths include part bandwidth 1 and part bandwidth 2, the terminal device can obtain, through the frequency domain resource indication information of the plurality of part bandwidths, that the bitmap of part bandwidth 1 is bitmap1 and the bitmap of part bandwidth 2 is bitmap2.

[0204] That is, in the case that the indication manner of the plurality of part bandwidths is bitmap, the frequency domain resource indication information of the plurality of part bandwidths can include a bitmap corresponding to each part bandwidth in the plurality of part bandwidths, so that the terminal can determine the plurality of part bandwidths through the bitmap corresponding to each part bandwidth.

[0205] Case 3 is that the indication manner of the plurality of part bandwidths includes RIV and bitmap.

[0206] In the case of the indication manner of the multiple part bandwidths being RIV and bitmap (i.e., case 3), at least one of the multiple part bandwidths can be indicated by RIV, and the other part bandwidths can be indicated by bitmap. That is, the method described in case 1 and the method described in case 2 can be combined. The frequency domain resource indication information of the multiple part bandwidths in case 3 can be understood with reference to the above-mentioned case 1 and case 2, and will not be described here.

[0207] For example, FIG. 9 shows an example of multiple part bandwidths. As shown in FIG. 9, assuming that the multiple part bandwidths include part bandwidth 1, part bandwidth 2, and part bandwidth 3, the terminal device can learn from the frequency domain resource indication information of the multiple part bandwidths that the bitmap of part bandwidth 1 is bitmap 1, and the bitmap of part bandwidth 3 is bitmap 2. The terminal device can also determine from the frequency domain resource indication information of the multiple part bandwidths that the RIV of part bandwidth 2 is RIV 2 according to the method described in case 1.

[0208] In addition, the configuration information of the multiple part bandwidths further includes the number of activated part bandwidths in the multiple part bandwidths excluding the first part bandwidth. For example, assuming that the multiple part bandwidths include part bandwidth 1 (i.e., the first part bandwidth), part bandwidth 2, part bandwidth 3, part bandwidth 4, and part bandwidth 5, and part bandwidths 1-3 are activated part bandwidths, in this case, the number of activated part bandwidths in the multiple part bandwidths excluding the first part bandwidth is 2. Generally, the number of activated part bandwidths in the multiple part bandwidths excluding the first part bandwidth occupies 2 bits.

[0209] That is, in addition to including at least one of the frequency domain resource starting position of the first part bandwidth, the number of activated frequency domain resource units of each part bandwidth in the multiple part bandwidths, or the number of configured frequency domain resource units of each part bandwidth, the configuration information of the multiple part bandwidths can further include the number of activated part bandwidths in the multiple part bandwidths excluding the first part bandwidth. In this way, the network device does not need to reserve a field for each part bandwidth to indicate whether it is activated, thereby saving signaling overhead.

[0210] Of course, the above is only an example of the configuration information of the multiple part bandwidths, and the configuration information of the multiple part bandwidths can also include other information, which is not limited by the embodiments of the present application.

[0211] The above S402 is described in detail as follows.

[0212] Optionally, as shown in FIG. 10, the implementation process of the above S402 can include the following S1001-S1003.

[0213] S1001, the network device transmits other system information based on a first transmission time interval on a first part of bandwidth. Correspondingly, the terminal receives other system information based on the first transmission time interval on the first part of bandwidth.

[0214] Optionally, the first transmission time interval can be configured through signaling. For example, the first transmission time interval is carried in the downlink control information (DCI) issued by the network device to the terminal. Of course, the above is only an exemplary description of the network device transmitting the first transmission time interval to the terminal, and the network device can also transmit the first transmission time interval to the terminal through other information, which is not limited by the embodiments of the present application.

[0215] Optionally, the transmission time interval described in the embodiments of the present application can be understood as TTI. Of course, the above is only an exemplary description of the transmission time interval, and the transmission time interval can also be understood as other time intervals, or the transmission time interval can also be called other names in other network architectures, which is not limited by the embodiments of the present application.

[0216] S1002, the network device determines a second transmission time interval for transmitting other system information on a second part of bandwidth based on the first transmission time interval, a subcarrier spacing corresponding to the first part of bandwidth, and a subcarrier spacing corresponding to the second part of bandwidth.

[0217] Among them, the second part of bandwidth is a part of bandwidth in the plurality of parts of bandwidth except the first part of bandwidth.

[0218] In a possible implementation, the second transmission time interval for transmitting other system information on the second part of bandwidth can satisfy the following formula 2:

[0219] Among them, K (2) is the second transmission time interval, K (1) is the first transmission time interval, μ2 is a parameter of the subcarrier spacing corresponding to the second part of bandwidth, μ1 is a parameter of the subcarrier spacing corresponding to the first part of bandwidth, and floor(x) represents rounding down x. For example, when the subcarrier spacing corresponding to the first part of bandwidth is 30 kHz and the subcarrier spacing corresponding to the second part of bandwidth is 15 kHz, μ1=1 and μ2=0.

[0220] In other possible implementations, the second transmission time interval for transmitting other system information on the second part of bandwidth can also satisfy the following formulas 3 to 7: K (2) = floor(K (1)(f2 / f1) ceil(K K (2) = ceil(K (1) (f2 / f1) ceil(K

[0221] wherein f2 is a subcarrier spacing corresponding to the second partial bandwidth, f1 is a subcarrier spacing corresponding to the first partial bandwidth, and ceil(x) represents rounding x up.

[0222] S1003, the network device transmits the other system information based on the second transmission time interval on the second partial bandwidth. Correspondingly, the terminal receives the other system information based on the second transmission time interval on the second partial bandwidth.

[0223] For example, FIG. 11 shows an example diagram of transmitting the other system information. As shown in FIG. 11, assuming that the first transmission time interval is the third time slot (e.g., time slot 2) in frame 1, the subcarrier spacing corresponding to the first partial bandwidth is 30 kHz, and the subcarrier spacing corresponding to the second partial bandwidth is 60 kHz, the network device can determine the second transmission time interval (e.g., time slot 2) according to the first transmission time interval, the subcarrier spacing corresponding to the first partial bandwidth, the subcarrier spacing corresponding to the second partial bandwidth, and formula 2. In this example, the network device can transmit the other system information based on time slot 2 on the first partial bandwidth, and transmit the other system information based on time slot 2 on the second partial bandwidth. Correspondingly, the terminal can receive the other system information based on time slot 2 on the first partial bandwidth, and receive the other system information based on time slot 2 on the second partial bandwidth.

[0224] That is, the network device can transmit the other system information based on different transmission time intervals on different partial bandwidths, to improve the flexibility of transmitting the other system information. In addition, there is a relationship between the second transmission time interval corresponding to the second partial bandwidth and the first transmission time interval corresponding to the first partial bandwidth, so that the terminal can determine the second transmission time interval based on the first transmission time interval and the subcarrier spacing, that is, the network device does not need to additionally indicate the second transmission time interval corresponding to the second partial bandwidth, thereby saving signaling overhead.

[0225] Optionally, the information transmission method provided by the embodiments of the present application not only involves the scheme of transmitting system information, but also involves the scheme of transmitting acknowledgement / negative acknowledgement feedback information. Specifically, the above-mentioned multiple partial bandwidths are also used to transmit the acknowledgement / negative acknowledgement feedback information. In view of this, as shown in FIG. 12, after the above-mentioned step S402, the information transmission method provided by the embodiments of the present application can further include the following steps:

[0226] S1201, the terminal transmits acknowledgement / negative acknowledgement feedback information on multiple partial bandwidths respectively. Correspondingly, the network device receives the acknowledgement / negative acknowledgement feedback information on the multiple partial bandwidths respectively.

[0227] Optionally, the acknowledgement / negative acknowledgement feedback information disclosed in the embodiments of the present application can be understood as transmission acknowledgement / negative acknowledgement (ACK / NACK) feedback information. Of course, the above is only an exemplary description of the acknowledgement / negative acknowledgement feedback information, and the acknowledgement / negative acknowledgement feedback information can also be understood as other information, or the acknowledgement / negative acknowledgement feedback information can also be called other names in other network architectures, and the embodiments of the present application do not make any limitation in this regard.

[0228] Further, optionally, the implementation process of S1201 can be that the terminal can transmit the acknowledgement / negative acknowledgement feedback information on the first partial bandwidth based on a third transmission time interval. Correspondingly, the network device receives the acknowledgement / negative acknowledgement feedback information on the first partial bandwidth based on the third transmission time interval. The terminal determines a fourth transmission time interval for transmitting the acknowledgement / negative acknowledgement feedback information on the second partial bandwidth based on the third transmission time interval, a subcarrier interval corresponding to the first partial bandwidth, and a subcarrier interval corresponding to the second partial bandwidth. The terminal transmits the acknowledgement / negative acknowledgement feedback information on the second partial bandwidth based on the fourth transmission time interval. Correspondingly, the network device receives the acknowledgement / negative acknowledgement feedback information on the second partial bandwidth based on the fourth transmission time interval.

[0229] In a possible implementation, the fourth transmission time interval of the acknowledgement / negative acknowledgement feedback information on the second partial bandwidth can satisfy the following formula 8:

[0230] wherein, K (4) is the fourth transmission time interval, K (3) is the third transmission time interval.

[0231] In other possible implementations, the fourth transmission time interval of the acknowledgement / negative acknowledgement feedback information on the second partial bandwidth can satisfy the following formulas 9 to 13: K (4) = floor(K (3) / (f2 / f1)) Formula 9 K (4) = ceil(K (3)(f2 / f1))-1 Formula 12

[0232] For example, FIG. 13 shows an example diagram of transmitting acknowledgement / negative-acknowledgement feedback information. As shown in FIG. 13, assuming that the fifth transmission time interval is the 10th time slot (e.g., time slot 9) in frame 1, the subcarrier spacing corresponding to the first partial bandwidth is 30 kHz, and the subcarrier spacing corresponding to the second partial bandwidth is 60 kHz, the terminal can determine the fourth transmission time interval (e.g., time slot 4) according to the third transmission time interval, the subcarrier spacing corresponding to the first partial bandwidth, the subcarrier spacing corresponding to the second partial bandwidth, and Formula 4. In this example, the terminal can transmit the acknowledgement / negative-acknowledgement feedback information based on time slot 9 on the first partial bandwidth, and transmit the acknowledgement / negative-acknowledgement feedback information based on time slot 4 on the second partial bandwidth. Correspondingly, the network device can receive the acknowledgement / negative-acknowledgement feedback information based on time slot 9 on the first partial bandwidth, and receive the acknowledgement / negative-acknowledgement feedback information based on time slot 4 on the second partial bandwidth.

[0233] That is, in the information transmission method provided by the embodiments of the present application, the network device can not only transmit other system information on multiple partial bandwidths respectively, but also receive acknowledgement / negative-acknowledgement feedback information on the multiple partial bandwidths respectively. Since the subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the multiple partial bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first partial bandwidth for transmitting the first information and the acknowledgement / negative-acknowledgement feedback information, so that the unit transmission time interval corresponding to the first partial bandwidth becomes shorter, which makes the time interval between transmitting the first information and the acknowledgement / negative-acknowledgement feedback information shorter in the case of the same number of transmission time intervals. That is, based on the above scheme, the terminal can transmit the acknowledgement / negative-acknowledgement feedback information on the first partial bandwidth as soon as possible, reduce the time delay of the acknowledgement / negative-acknowledgement feedback information sent by the terminal on the first partial bandwidth, and further reduce the overall time delay of the terminal sending the acknowledgement / negative-acknowledgement feedback information on the multiple partial bandwidths.

[0234] Optionally, in addition to the scheme for transmitting system information, the information transmission method provided by the embodiments of the present application also relates to a scheme for transmitting uplink shared signals. Specifically, the multiple partial bandwidths are also used for uplink shared signals. In view of this, as shown in FIG. 14, after the step S402, the information transmission method provided by the embodiments of the present application can further include the following steps:

[0235] S1401. The terminal transmits the uplink shared signals on the multiple part-bandwidths respectively. Correspondingly, the network device receives the uplink shared signals on the multiple part-bandwidths respectively.

[0236] Further, optionally, the implementation process of S1401 can be that the terminal transmits the uplink shared signal on the first part-bandwidth based on the fifth transmission time interval. Correspondingly, the network device receives the uplink shared signal on the first part-bandwidth based on the fifth transmission time interval. The terminal determines the sixth transmission time interval for transmitting the uplink shared signal on the second part-bandwidth based on the fifth transmission time interval, the subcarrier interval corresponding to the first part-bandwidth, and the subcarrier interval corresponding to the second part-bandwidth. The terminal transmits the uplink shared signal on the second part-bandwidth based on the sixth transmission time interval. Correspondingly, the network device receives the uplink shared signal on the second part-bandwidth based on the sixth transmission time interval.

[0237] In a possible implementation, the sixth transmission time interval for transmitting the uplink shared signal on the second part-bandwidth can satisfy the following formula 14:

[0238] wherein K (6) is the sixth transmission time interval, K (1) is the fifth transmission time interval.

[0239] In other possible implementations, the sixth transmission time interval for transmitting the uplink shared signal on the second part-bandwidth can satisfy the following formula 15 to formula 19: K (6) = floor(K (5) / (f2 / f1)) formula 15 K (6) = ceil(K (5) / (f2 / f1))-1 formula 18

[0240] Optionally, the implementation process of S1401 can be that the terminal transmits the uplink shared signal on the multiple part-bandwidths based on a third frequency hopping pattern. Correspondingly, the network device receives the uplink shared signal on the multiple part-bandwidths based on the third frequency hopping pattern. The third frequency hopping pattern is configured for the uplink shared signals transmitted on the multiple part-bandwidths.

[0241] Optionally, the third frequency hopping pattern can be configured through signaling. For example, the third frequency hopping pattern is carried in DCI sent by the network device to the terminal. Of course, the above is only an exemplary description of the network device transmitting the third frequency hopping pattern to the terminal, and the network device can also transmit the third frequency hopping pattern to the terminal through other information, and the embodiments of the present application do not make any limitation in this regard.

[0242] For example, FIG. 15 shows an example diagram of transmitting an uplink shared signal. As shown in FIG. 15, assuming that the fifth transmission time interval is the 10th time slot (for example, time slot 9) in frame 1, the subcarrier spacing corresponding to the first partial bandwidth is 30 kHz, and the subcarrier spacing corresponding to the second partial bandwidth is 60 kHz, the terminal can determine the sixth transmission time interval (for example, time slot 4) according to the fifth transmission time interval, the subcarrier spacing corresponding to the first partial bandwidth, the subcarrier spacing corresponding to the second partial bandwidth, and formula 4. In this example, the terminal can transmit the uplink shared signal based on time slot 9 on the first partial bandwidth, and transmit the uplink shared signal based on time slot 4 on the second partial bandwidth. Correspondingly, the network device can receive the uplink shared signal based on time slot 9 on the first partial bandwidth, and receive the uplink shared signal based on time slot 4 on the second partial bandwidth.

[0243] That is, in the information transmission method provided by the embodiments of the present application, the network device can not only transmit other system information on multiple partial bandwidths respectively, but also receive uplink shared signals on the multiple partial bandwidths respectively. Since the subcarrier spacing corresponding to the first partial bandwidth is greater than the subcarrier spacing corresponding to other partial bandwidths in the multiple partial bandwidths configured for the terminal, that is, the network device expands the subcarrier spacing corresponding to the first partial bandwidth used to transmit the first information and the uplink shared signal, so that the unit transmission time interval corresponding to the first partial bandwidth becomes shorter, so that the time interval between transmitting the first information and the uplink shared signal can be shortened in the case of the same number of transmission time intervals. That is, based on the above scheme, the terminal can transmit the uplink shared signal on the first partial bandwidth as soon as possible, reduce the time delay of the uplink shared signal sent by the terminal on the first partial bandwidth, and further reduce the overall time delay of the terminal sending the uplink shared signal on the multiple partial bandwidths.

[0244] It should be noted that in the case that multiple partial bandwidths are occupied for information transmission between the network device and the terminal, it is possible that the uplink bandwidth and the downlink bandwidth are different. However, if the uplink bandwidth and the downlink bandwidth are different, the network device can normally receive the sounding reference signal on the overlapping bandwidth (denoted as the overlapping bandwidth) between the uplink bandwidth and the downlink bandwidth, so that the network device can learn the state of the channel based on the sounding reference signal, and adaptively transmit information to the terminal based on the state of the channel. On the bandwidth other than the overlapping bandwidth in the downlink bandwidth, the network device cannot normally receive the sounding reference signal, resulting in that the network device needs to learn the state of the channel by relying on the sounding reference signal received on other partial bandwidths, which can cause the problem of inaccurate channel state learning, that is, inaccurate channel measurement. In view of this, the embodiment of the present application provides another information transmission method, in which the network device transmits sounding reference signals on multiple partial bandwidths respectively, so that the network device can receive more sounding reference signals, and the network device can obtain more comprehensive channel information by measuring the more sounding reference signals, thereby improving the accuracy of channel measurement. As shown in FIG. 16, after the step S402, the information transmission method provided by the embodiment of the present application can further include the following steps:

[0245] S1601, the terminal transmits sounding reference signals on multiple partial bandwidths respectively. Correspondingly, the network device receives the sounding reference signals on multiple partial bandwidths respectively.

[0246] Optionally, after S1601, the network device can measure the sounding reference signals to learn a channel matrix, the channel matrix being used to reflect the state of the channel for transmitting the sounding reference signals. The network device calculates downlink beam weights based on the channel matrix, so as to transmit downlink signals based on the downlink beam weights.

[0247] That is, in the information transmission method provided by the embodiment of the present application, the network device can receive the sounding reference signals on multiple partial bandwidths respectively. That is, the network device can receive more sounding reference signals, so that the network device can obtain more comprehensive channel information by measuring the more sounding reference signals, thereby improving the accuracy of channel measurement.

[0248] In addition, it should be noted that the information transmission method provided by the embodiment of the present application does not limit the order in which the terminal transmits the uplink shared signal and the sounding reference signal. That is, the terminal can first transmit the sounding reference signals on multiple partial bandwidths respectively, and then transmit the uplink shared signals on multiple partial bandwidths respectively; or the terminal can first transmit the uplink shared signals on multiple partial bandwidths respectively, and then transmit the sounding reference signals on multiple partial bandwidths respectively.

[0249] Further, the S1601 can be determined by two implementation manners, that is, the terminal can transmit the sounding reference signals on the multiple partial bandwidths in the following two manners: manner one is that the terminal can transmit the sounding reference signals on the entire multiple partial bandwidths; and manner two is that the terminal can transmit the sounding reference signals on part of the multiple partial bandwidths. Of course, the above is only an exemplary description of the implementation manner of transmitting the sounding reference signals on the multiple partial bandwidths by the terminal, and the terminal can also transmit the sounding reference signals on the multiple partial bandwidths in other manners, which is not limited in the embodiment of the present application.

[0250] The above manner one and manner two are described in detail as follows:

[0251] The manner one is that the terminal can transmit the sounding reference signals on the entire multiple partial bandwidths. As shown in FIG. 17, in the manner one, the S1601 can be implemented by S1701.

[0252] In the S1701, the terminal transmits the sounding reference signals on the multiple partial bandwidths based on a second frequency hopping pattern. Correspondingly, the network device receives the sounding reference signals on the multiple partial bandwidths based on the second frequency hopping pattern.

[0253] It can be understood that the second frequency hopping pattern is configured for the sounding reference signals transmitted on the multiple partial bandwidths.

[0254] Optionally, the second frequency hopping pattern can be configured by signaling. For example, the second frequency hopping pattern is carried in the DCI issued by the network device to the terminal. Of course, the above is only an exemplary description of transmitting the second frequency hopping pattern by the network device to the terminal, and the network device can also transmit the second frequency hopping pattern to the terminal by other information, which is not limited in the embodiment of the present application.

[0255] For example, FIG. 18 shows an example diagram of transmitting the sounding reference signals based on the second frequency hopping pattern. As shown in FIG. 18, assuming that the multiple partial bandwidths include partial bandwidth 1, partial bandwidth 2, partial bandwidth 3, partial bandwidth 4, and partial bandwidth 5, and the second frequency hopping pattern is used for indication, the terminal can transmit the sounding reference signals based on the transmission time interval 1 in the partial frequency domain resources in the partial bandwidth 1, transmit the sounding reference signals based on the transmission time interval 2 in the partial frequency domain resources in the partial bandwidth 2, transmit the sounding reference signals based on the transmission time interval 3 in the partial frequency domain resources in the partial bandwidth 3, transmit the sounding reference signals based on the transmission time interval 4 in the partial frequency domain resources in the partial bandwidth 4, and transmit the sounding reference signals based on the transmission time interval 5 in the partial frequency domain resources in the partial bandwidth 5.

[0256] That is, the network device can also receive the sounding reference signals respectively transmitted through frequency hopping on multiple partial bandwidths, thereby improving the anti-interference of the sounding reference signals.

[0257] The second mode is that the terminal can transmit the sounding reference signals respectively on multiple partial bandwidths. As shown in FIG. 17, in the second mode, S1601 can be implemented through S1702 and S1703.

[0258] S1702, the network device transmits second information. Correspondingly, the terminal receives the second information.

[0259] The second information is used to indicate a third partial bandwidth in the multiple partial bandwidths.

[0260] Optionally, the third partial bandwidth can include some or all of the multiple partial bandwidths. That is, the number of partial bandwidths included in the third partial bandwidth is not limited in the embodiments of the present application.

[0261] S1703, the terminal transmits the sounding reference signals on the third partial bandwidth. Correspondingly, the network device receives the sounding reference signals on the third partial bandwidth.

[0262] That is, in addition to receiving the sounding reference signals respectively on multiple partial bandwidths, the network device can also receive the sounding reference signals on some partial bandwidths (i.e., the third partial bandwidth) in the multiple partial bandwidths. That is, the network device does not need to receive the sounding reference signals on each partial bandwidth, thereby reducing the number of times of transmitting the sounding reference signals, and further reducing the communication overhead of transmitting the sounding reference signals.

[0263] Further, optionally, the implementation process of S1703 can be that the terminal transmits the sounding reference signals on the third partial bandwidth based on a first frequency hopping pattern. Correspondingly, the network device receives the sounding reference signals on the third partial bandwidth based on the first frequency hopping pattern.

[0264] It can be understood that the first frequency hopping pattern is configured for the sounding reference signals transmitted on the third partial bandwidth.

[0265] Optionally, the first frequency hopping pattern can be configured through signaling. For example, the first frequency hopping pattern is carried in the DCI issued by the network device to the terminal. Of course, the above is only an exemplary description of the network device transmitting the first frequency hopping pattern to the terminal, and the network device can also transmit the first frequency hopping pattern to the terminal through other information, which is not limited in the embodiments of the present application.

[0266] For example, FIG. 19 shows an example diagram of transmitting a sounding reference signal based on a first frequency hopping pattern. As shown in FIG. 19, assuming that multiple partial bandwidths include partial bandwidth 1, partial bandwidth 2, partial bandwidth 3, partial bandwidth 4, and partial bandwidth 5, the third partial bandwidth includes partial bandwidth 1, partial bandwidth 3, and partial bandwidth 4, and the first frequency hopping pattern is used for indication, the terminal can transmit a sounding reference signal based on transmission time interval 1 within partial frequency domain resources in the partial bandwidth 1, can transmit a sounding reference signal based on transmission time interval 2 within partial frequency domain resources in the partial bandwidth 3, and can transmit a sounding reference signal based on transmission time interval 3 within partial frequency domain resources in the partial bandwidth 4.

[0267] That is, the network device can also receive the sounding reference signal on the third partial bandwidth in a frequency hopping transmission manner, improving the anti-interference of the sounding reference signal transmission.
