[0031] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms "a," "the," and "the" used in this application and claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to any or all possible combinations of one or more associated listed items.

[0032] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" used may also be interpreted as "at the time of" or "when" or "in response to determining".

[0033] TDD systems can operate in HD mode, meaning that at the same time, the same frequency domain resources can only be used for UL or DL. To make more flexible use of frequency domain resources and improve resource utilization, TDD systems can also operate in FD (Full-Duplex) mode, meaning that at the same time, the same frequency domain resources are used for both UL and DL, that is, uplink and downlink data are processed simultaneously on the same frequency domain resources.

[0034] In a TDD system, the frame structure is divided into DL time slots, UL time slots, and flexible time slots. Once the frame structure is determined, the UE can transmit and receive data according to the frame structure. For UEs using HD (Half Duplex) mode, the base station (such as a gNB) schedules the UE to transmit or receive according to the frame structure. For UEs using FD mode, the base station schedules the UE to transmit, receive, or both according to the frame structure. In summary, the base station can configure the frame structure and notify the UE of the frame structure so that the UE understands the frame structure and can correctly transmit and receive data. Furthermore, after understanding the frame structure, the UE can be aware of potential inter-UE interference and use interference cancellation techniques to mitigate interference and improve communication reliability.

[0035] For example, in a TDD system, for a frame structure primarily used for downlink transmission, more DL time slots are usually configured. This results in fewer UL time slots, which in turn limits the uplink transmission rate and increases the transmission delay of uplink data, resulting in a longer uplink transmission delay and the unutilization of uplink services.

[0036] In one example, a method for transmitting SRS frequency-hopping signals is proposed. This method uses SBFD time-frequency resources to configure flexible downlink and uplink frequency domain resources for UEs. This allows uplink data to be transmitted using the uplink frequency domain resources. This means that uplink frequency domain resources can be configured using downlink time slots or flexible time slots, and uplink data can be transmitted using these resources. This improves the uplink transmission rate and reduces the transmission latency of uplink data. Furthermore, downlink frequency domain resources can be configured using uplink time slots or flexible time slots, and downlink data can be transmitted using these resources. This improves the downlink transmission rate and reduces the transmission latency of downlink data.

[0037] In one example of the present application, a method for transmitting an SRS frequency hopping signal is proposed, which can be applied to a base station. FIG1A is a flow chart of the method for transmitting an SRS frequency hopping signal. The method may include:

[0038] Step 111: Send SRS frequency hopping transmission configuration information to the user equipment. The SRS frequency hopping transmission configuration information is used to indicate an SRS frequency hopping resource set, and the SRS frequency hopping resource set may include multiple SRS frequency hopping resources. For each SRS frequency hopping resource, the SRS frequency hopping resource is located in an uplink time slot or uplink symbol, or the SRS frequency hopping resource is located in an uplink subband of an SBFD time-frequency resource. The SBFD time-frequency resource is located in a downlink time slot or downlink symbol, or the SBFD time-frequency resource is located in an F time slot or F symbol.

[0039] Step 112: Receive an SRS frequency hopping signal sent by the user equipment to the base station based on the SRS frequency hopping resource.

[0040] In one example of the present application, a method for transmitting an SRS frequency hopping signal is proposed, which can be applied to a user equipment. FIG1B is a flow chart of the method for transmitting an SRS frequency hopping signal. The method may include:

[0041] Step 121: Receive SRS frequency hopping transmission configuration information sent by a base station. The SRS frequency hopping transmission configuration information is used to indicate an SRS frequency hopping resource set. The SRS frequency hopping resource set may include multiple SRS frequency hopping resources. Each SRS frequency hopping resource is located in an uplink time slot or uplink symbol, or is located within an uplink subband of an SBFD time-frequency resource. The SBFD time-frequency resource is located in a downlink time slot or downlink symbol, or is located in an F time slot or F symbol.

[0042] Step 122: Send an SRS frequency hopping signal to the base station based on each SRS frequency hopping resource in the SRS frequency hopping resource set. For example, determine the SRS frequency hopping resource set based on the SRS frequency hopping transmission configuration information, and send an SRS frequency hopping signal to the base station based on each SRS frequency hopping resource in the SRS frequency hopping resource set.

[0043] In one example, the multiple SRS frequency hopping resources in the SRS frequency hopping resource set may be periodic multiple SRS frequency hopping resources or aperiodic multiple SRS frequency hopping resources. The SRS frequency hopping transmission configuration information may indicate the time slot occupied by the SRS frequency hopping resource and the symbol occupied in the time slot, and indicate which frequency domain resources (e.g., PRB resources) in the symbol are occupied by the SRS frequency hopping resource.

[0044] In one example, the SRS frequency hopping transmission configuration information may include first SRS frequency hopping transmission configuration information and second SRS frequency hopping transmission configuration information. The first SRS frequency hopping transmission configuration information is used to indicate a first SRS frequency hopping resource set, which includes SRS frequency hopping resources located in an uplink subband of an SBFD time-frequency resource. The second SRS frequency hopping transmission configuration information is used to indicate a second SRS frequency hopping resource set, which includes SRS frequency hopping resources located in an uplink time slot or uplink symbol.

[0045] In one example, the SRS frequency hopping transmission configuration information may include third SRS frequency hopping transmission configuration information, and the third SRS frequency hopping transmission configuration information is used to indicate a third SRS frequency hopping resource set. The third SRS frequency hopping resource set includes SRS frequency hopping resources located in an uplink subband of an SBFD time-frequency resource, and / or the third SRS frequency hopping resource set includes SRS frequency hopping resources located in an uplink time slot or uplink symbol.

[0046] As can be seen from the above technical solution, the UE uses the SRS frequency hopping resources in the SRS frequency hopping resource set to send SRS frequency hopping signals to the base station. The SRS frequency hopping resources can be located in the uplink subband of SBFD, thereby utilizing SBFD time-frequency resources to transmit SRS frequency hopping signals, improving the transmission reliability and cell coverage radius of uplink data, enhancing the accuracy of downlink beamforming and the real-time performance of beam tracking, reducing the interference of uplink and downlink data transmission caused by the introduction of SBFD time-frequency resources, and enabling the effective combination and implementation of SBFD time-frequency resource configuration and SRS frequency hopping signal transmission mechanism. From the perspective of the entire system, it supports SRS frequency hopping signal transmission in the TDD system, improves resource utilization, improves network coverage and network capacity, increases uplink transmission resources and uplink transmission reliability, reduces uplink transmission delay and increases uplink transmission capacity, and provides support for path loss and positioning measurement.

[0047] The above technical solution of the present application is described below with reference to examples.

[0048] The TDD frame structure can be implemented through a combination of semi-static configuration and dynamic indication. Multiple SFCs (Slot Format Combinations) are defined in high-layer signaling using the SFI (Slot Format Indicator). For example, a base station can select slot formats that meet service requirements and add them to the SFC. Table 1 shows some of the slot formats, where D represents a DL symbol, U represents an UL symbol, and F represents a flexible symbol. Each SFC is identified by a fixed ID and contains one or more slot format types.

[0049] Table 1

[0050] After completing SFI configuration, the base station sends multiple slot format combinations to the UE in an RRC message. After configuring multiple slot format combinations via RRC signaling, the base station notifies the UE of the index of the currently used SFC via periodic PDCCH in DCI format 2_0. After correctly receiving the DCI format 2_0 information, the UE determines the slot format for each slot within a certain period based on the SFC index value. At this point, the base station and UE have completed the frame structure configuration through dynamic indication, enabling uplink and downlink data transmission.

[0051] For resource allocation, it can be divided into time domain resource allocation and frequency domain resource allocation (taking the resource allocation of the downlink channel as an example). Time domain resource allocation: The Time domain resource assignment field in the DCI indicates the time domain position of the downlink channel. This field has a total of 4 bits, with values ​​from 0 to 15. Assuming the value is m, then m+1 indicates the row index of the time domain resource allocation table, and the information in this row indicates the time domain resources of the PDSCH. There are two ways of indication: one is to indicate three pieces of information: the time slot offset between the PDSCH and the PDCCH that schedules the PDSCH, the starting symbol of the PDSCH in the time slot, and the symbol length of the PDSCH. The other is to indicate the time slot offset between the PDSCH and the PDCCH that schedules the PDSCH, and a SLIV value. The user equipment calculates the starting symbol and the number of continuous symbols of the PDSCH based on the SLIV value.

[0052] Frequency domain resource allocation: The Frequency domain resource assignment field in the DCI indicates the frequency domain resource allocation of the downlink channel. PDSCH frequency domain resource allocation is divided into Type 0 and Type 1. Type 0 supports non-contiguous resource allocation to obtain frequency diversity gain, and Type 1 supports continuous resource allocation, which can reduce the number of bits required for this field. DCI format 1_0 only supports Type 1. Type 0: For the non-contiguous resource allocation type, an RBG is a VRB group, which consists of P consecutive VRBs. The number is determined by the high-level parameters rbg-Size and BWP bandwidth. Under the resource allocation type of Type 0, Frequency domain resource assignment is used as a bitmap to indicate which RBGs are allocated to the downlink channel. Each bit in the bitmap represents an RBG, and the highest bit corresponds to RBG0. Similarly, a bit of 1 indicates that the RBG is allocated to the downlink channel, and a bit of 0 indicates that it is not a downlink channel resource. Type 1: The frequency domain resource indication field does not serve as a bitmap, but indicates a RIV (Resource Indicator Value) value, which is used by the user equipment to calculate the starting RB and the number of occupied RBs of the downlink channel.

[0053] In a TDD system, the frame structure can be divided into UL time slots, DL time slots, and flexible time slots according to time slots. The symbols in the flexible time slots can be configured as UL symbols, DL symbols, and F symbols. F symbols can be used for UL, DL, or GP. Among them, uplink data can be transmitted in the UL time slot, UL symbols in the flexible time slot, or F symbols. Uplink data cannot be transmitted in the DL time slot or the DL symbols in the flexible time slot. Similarly, downlink data can be transmitted in the DL time slot, DL symbols in the flexible time slot, or F symbols. Downlink data cannot be transmitted in the UL time slot or the UL symbols in the flexible time slot.

[0054] Full-duplex communication can be achieved through SBFD, that is, SBFD time-frequency resources can be configured in time-frequency resources (such as UL time slots, DL time slots, and flexible time slots). In this way, at the same time, data in different directions from other time-frequency resources can be transmitted on the SBFD time-frequency resources. For example, SBFD time-frequency resources are configured in the DL time slot, and uplink data is transmitted via the SBFD time-frequency resources, so that the uplink data is transmitted in the DL time slot. For another example, SBFD time-frequency resources are configured in the DL symbols of the flexible time slot, and uplink data is transmitted via the SBFD time-frequency resources, so that the uplink data is transmitted in the DL symbols of the flexible time slot. For another example, SBFD time-frequency resources are configured in the UL time slot, and downlink data is transmitted via the SBFD time-frequency resources, so that the downlink data is transmitted in the UL time slot. For another example, SBFD time-frequency resources are configured in the UL symbols of the flexible time slot, and downlink data is transmitted via the SBFD time-frequency resources, so that the downlink data is transmitted in the UL symbols of the flexible time slot.

[0055] In an example, the SBFD time-frequency resource may be the time-frequency resource corresponding to the SBFD time slot or the time-frequency resource corresponding to the SBFD symbol. The SBFD symbol may be defined as a symbol that the base station and the UE may be configured with an SBFD sub-band. On the SBFD sub-band of these SBFD symbols (referred to as SBFD time-frequency resources), the base station and the UE may perform full-duplex communication. That is, uplink transmission, downlink transmission, or simultaneous uplink and downlink transmission may be performed on the SBFD time-frequency resources. The SBFD time-frequency resource may be explicitly indicated as uplink, downlink, or flexible. When the SBFD time-frequency resource is indicated as flexible, uplink or downlink may be flexibly scheduled on the SBFD time-frequency resource. If the SBFD time-frequency resource is not explicitly indicated, it means that it is flexible and can be used to transmit uplink or downlink data. The configuration of the SBFD time slot or SBFD symbol may include: which symbols in the DL time slot, UL time slot, and F time slot are used for SBFD transmission, as well as the implementation period and starting point, etc. For the convenience of description, in the subsequent embodiments, the SBFD time-frequency resources are time-frequency resources corresponding to the SBFD time slots as an example for description.

[0056] In one example, SBFD indicated as uplink is called UL-SBFD, i.e., SBFD time-frequency resources are used for uplink, and SBFD indicated as downlink is called DL-SBFD, i.e., SBFD time-frequency resources are used for downlink. To support FD communication, SBFD time-frequency resources can be semi-statically configured, such as through RRC (Radio Resource Control) signaling, or dynamically configured, such as through DCI (Downlink Control Information).

[0057] SBFD time-frequency resources can be configured in DL symbols, F symbols, and UL symbols. Symbols configured with SBFD time-frequency resources are called SBFD symbols, while the remaining symbols without SBFD time-frequency resources are called normal symbols. That is, non-SBFD symbols are called normal symbols, such as UL symbols, DL symbols, and F symbols. SBFD can be configured in some symbols of a timeslot. That is, some symbols of a timeslot are SBFD symbols, while the rest are normal symbols. This allows DL or UL data transmission to span normal symbols or SBFD symbols.

[0058] In one example, SBFD time-frequency resources located in a downlink timeslot means that SBFD time-frequency resources are configured in the downlink timeslot, such as configuring SBFD time-frequency resources for a symbol or multiple symbols in the downlink timeslot. SBFD time-frequency resources located in a downlink symbol means that SBFD time-frequency resources are configured for a downlink symbol. The downlink symbol may be a downlink symbol in the downlink timeslot, a downlink symbol in the F timeslot, or a downlink symbol in the uplink timeslot. SBFD time-frequency resources located in the F timeslot means that SBFD time-frequency resources are configured in the F timeslot, such as configuring SBFD time-frequency resources for a symbol or multiple symbols in the F timeslot. SBFD time-frequency resources located in the F symbol means that SBFD time-frequency resources are configured for the F symbol. The F symbol may be an F symbol in the downlink timeslot, an F symbol in the F timeslot, or an F symbol in the uplink timeslot. SBFD time-frequency resources located in the uplink timeslot means that SBFD time-frequency resources are configured in the uplink timeslot, such as configuring SBFD time-frequency resources for a symbol or multiple symbols in the uplink timeslot. The SBFD time-frequency resource is located in the uplink symbol, which means that the SBFD time-frequency resource is configured in the uplink symbol. The uplink symbol may be an uplink symbol in an uplink timeslot, an uplink symbol in an F timeslot, or an uplink symbol in a downlink timeslot.

[0059] In an example, a UE can send an SRS frequency hopping signal to a base station. In the full-duplex mode of TDD, an SRS frequency hopping signal transmission method is proposed. After configuring SBFD time-frequency resources, if the SRS frequency hopping resources overlap with the SBFD time-frequency resources, an SRS frequency hopping signal transmission method between the UE and the base station is given. The SRS frequency hopping resources can be configured to SBFD time slots / SBFD symbols and non-SBFD time slots / non-SBFD symbols (i.e., ordinary time slots / ordinary symbols) at the same time, so that the UE and the base station can transmit SRS frequency hopping signals in SBFD time slots or SBFD symbols, and can also transmit SRS frequency hopping signals in non-SBFD time slots / non-SBFD symbols.

[0060] For example, after configuring the SBFD time-frequency resources, if the SRS frequency hopping resources (also referred to as the SRS frequency hopping bandwidth) exceed the uplink subband of the SBFD time-frequency resources (also referred to as the configured bandwidth of the uplink subband of the SBFD time-frequency resources), then how to configure the SRS frequency hopping resources and how to transmit the SRS frequency hopping signal in this case are given. For another example, after inserting the downlink subband and / or protection subband of the SBFD time-frequency resources into the uplink time slot, if the resources of the uplink time slot are discontinuous, then how to configure the SRS frequency hopping resources and how to transmit the SRS frequency hopping signal in this case are given. In response to the above problems, SRS frequency hopping design schemes and power allocation schemes for different scenarios are proposed to solve the problem of base stations and UEs transmitting SRS frequency hopping signals.

[0061] In an example, for the SRS frequency hopping transmission configuration based on SBFD time-frequency resources, the following methods can be adopted: the first method is that the base station configures a dedicated SRS frequency hopping resource set for the UE for the SBFD time slot / SBFD symbol; the second method is that the base station configures a unified SRS frequency hopping resource set for the UE for the SBFD time slot / SBFD symbol and the non-SBFD time slot / non-SBFD symbol. These two configuration methods are explained below.

[0062] Case 1: For the SBFD time slot or SBFD symbol, the base station configures a dedicated SRS frequency hopping resource set for the UE, which is called the first SRS frequency hopping resource set. The first SRS frequency hopping resource set may include SRS frequency hopping resources located in the uplink subband of the SBFD time-frequency resources.

[0063] In an example, an uplink subband (i.e., UL subband) of an SBFD time-frequency resource may be configured in a downlink time slot or downlink symbol, and an uplink subband of an SBFD time-frequency resource may be configured in an F time slot or F symbol. When the uplink subband of an SBFD time-frequency resource is configured for a downlink time slot or downlink symbol, an F time slot or F symbol, in order to ensure that each hop of the SRS frequency hopping resource (i.e., each SRS frequency hopping resource in the first SRS frequency hopping resource set) does not exceed the uplink subband of the SBFD time-frequency resource, the following solution may be adopted:

[0064] Solution A: The first SRS frequency hopping resource set configured by the base station does not exceed the frequency domain resource range of the uplink subband of the SBFD time-frequency resources, and each SRS frequency hopping resource within the first SRS frequency hopping resource set does not exceed the range of the first SRS frequency hopping resource set. That is, when configuring the SRS frequency hopping resources, each SRS frequency hopping resource needs to be located in the uplink subband of the SBFD time-frequency resources. In order to ensure that each SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resources, the base station can configure multiple SRS frequency hopping resources for the UE. The starting position and end position of each SRS frequency hopping resource need to be located within the uplink subband of the SBFD time-frequency resources. In this way, the first SRS frequency hopping resource set can be generated, and the first SRS frequency hopping resource set can include these multiple SRS frequency hopping resources.

[0065] Among them, the starting position of the SRS frequency hopping resource is located within the uplink subband of the SBFD time-frequency resource, which may include: the PRB index of the starting position of the SRS frequency hopping resource is greater than or equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the starting position of the SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource.

[0066] Among them, the end position of the SRS frequency hopping resource is located within the uplink subband of the SBFD time-frequency resource, which may include: the PRB index of the end position of the SRS frequency hopping resource is greater than or equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the end position of the SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource.

[0067] To summarize, the starting position and ending position of each SRS frequency hopping resource should follow the following strategy: the lowest PRB index of the uplink subband ≤ the PRB index of the starting position of each hop SRS frequency hopping resource ≤ the highest PRB index of the uplink subband, the PRB index of the ending position of each hop SRS frequency hopping resource ≤ the highest PRB index of the uplink subband, and the PRB index of the ending position will be greater than the PRB index of the starting position, that is, the sum of the bandwidths of all hops of the SRS frequency hopping resource is not greater than the bandwidth of the uplink subband of the SBFD time-frequency resource, and the lowest PRB index of all hops ≥ the lowest PRB index of the uplink subband.

[0068] In an example, for the multiple SRS frequency hopping resources in the first SRS frequency hopping resource set, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources between time slots (Inter-slot); or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources within a time slot (Intra-slot); or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources with repeated transmission between time slots; or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources with repeated transmission within a time slot, and there is no restriction on this.

[0069] Referring to FIG2A , which is a schematic diagram of multiple SRS frequency hopping resources between time slots, an uplink subband (UL subband) of an SBFD time-frequency resource can be configured in four consecutive downlink time slots or F time slots. The last symbol of each time slot is used to transmit the SRS frequency hopping signal. For the first and third hops, the PRB index of the starting position of the SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband, and the PRB index of the starting position of the SRS frequency hopping resource ≤ the PRB index of the ending position of the SRS frequency hopping resource ≤ the highest PRB index of the uplink subband. For the second and fourth hops, the PRB index of the ending position of the SRS frequency hopping resource is equal to the highest PRB index of the uplink subband, and the lowest PRB index of the uplink subband ≤ the PRB index of the starting position of the SRS frequency hopping resource ≤ the PRB index of the ending position of the SRS frequency hopping resource.

[0070] Referring to Figure 2B , which is a schematic diagram of multiple SRS frequency-hopping resources within a time slot, the uplink subband of the SBFD time-frequency resource can be configured in four consecutive downlink time slots or F time slots. Unlike Figure 2A , a complete SRS frequency-hopping signal transmission (including all SRS hops) is completed within a time slot. For example, the first and second hops represent all SRS hops within one time slot, and the third and fourth hops represent all SRS hops within another time slot. For each SRS frequency-hopping resource, it must be located in the uplink subband of the SBFD time-frequency resource, i.e., both the starting and ending positions are located in the uplink subband. This description will not be repeated here.

[0071] Referring to FIG2C , which is a schematic diagram of multiple SRS frequency-hopping resources with repeated transmission within a time slot, the uplink subband of the SBFD time-frequency resource can be configured in four consecutive downlink time slots or F time slots. Unlike FIG2A , a complete SRS frequency-hopping signal transmission (including all SRS hops) is completed within one time slot, and each SRS frequency-hopping signal is transmitted repeatedly, such as the first and second hops are repeated transmissions, the third and fourth hops are repeated transmissions, the fifth and sixth hops are repeated transmissions, and the seventh and eighth hops are repeated transmissions. For each SRS frequency-hopping resource, the SRS frequency-hopping resource needs to be located in the uplink subband of the SBFD time-frequency resource, that is, the starting position and the end position are both located in the uplink subband, which will not be described in detail here.

[0072] Solution B: When the base station configures the SRS frequency hopping resources, it does not need to ensure that each SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resources. Instead, after configuring the SRS frequency hopping resources (the configured SRS frequency hopping resources are called original SRS frequency hopping resources, which can also be called SRS frequency hopping resource configuration), the SRS frequency hopping resources are optimized to obtain target SRS frequency hopping resources that meet the requirements. In this way, the target SRS frequency hopping resources corresponding to all original SRS frequency hopping resources can be combined into a first SRS frequency hopping resource set.

[0073] For example, the base station can configure multiple original SRS frequency hopping resources for the UE. The original SRS frequency hopping resources may be located in the uplink subband of the SBFD time-frequency resources, or may exceed the range of the uplink subband of the SBFD time-frequency resources. By optimizing the original SRS frequency hopping resources, the target SRS frequency hopping resources corresponding to the original SRS frequency hopping resources are obtained, and then a first SRS frequency hopping resource set is generated. The first SRS frequency hopping resource set includes the target SRS frequency hopping resources corresponding to all the original SRS frequency hopping resources.

[0074] When the base station configures the original SRS frequency hopping resources for the UE, the bandwidth configuration list may be used to configure the original SRS frequency hopping resources for the UE, and no restriction is imposed on the configuration process of the original SRS frequency hopping resources.

[0075] In an example, for each original SRS frequency hopping resource, taking an original SRS frequency hopping resource as an example, the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource may be determined in the following manner:

[0076] Mode 11: If the original SRS frequency hopping resource is located within the uplink sub-band of the SBFD time-frequency resource, that is, does not exceed the range of the uplink sub-band, then the original SRS frequency hopping resource is used as the target SRS frequency hopping resource.

[0077] Mode 12: If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is canceled, that is, there is no target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource, and the UE will not send an SRS frequency hopping signal on the original SRS frequency hopping resource.

[0078] Method 13: If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is used as the target SRS frequency hopping resource, even if the original SRS frequency hopping resource exceeds the range of the uplink subband, the original SRS frequency hopping resource is used as the target SRS frequency hopping resource.

[0079] For example, assuming that the original SRS frequency hopping resource includes a first SRS frequency hopping resource and a second SRS frequency hopping resource, the first SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource, and the second SRS frequency hopping resource exceeds the uplink subband range of the SBFD time-frequency resource (when exceeding the uplink subband range, the second SRS frequency hopping resource may be located in the downlink subband or the protection subband), then the original SRS frequency hopping resource (i.e., the first SRS frequency hopping resource and the second SRS frequency hopping resource) is used as the target SRS frequency hopping resource.

[0080] Method 14: If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, the original SRS frequency hopping resource includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then the first SRS frequency hopping resource is used as the target SRS frequency hopping resource, but the second SRS frequency hopping resource is not used as the target SRS frequency hopping resource, that is, the target SRS frequency hopping resource only includes the first SRS frequency hopping resource.

[0081] Method 15: If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then the original SRS frequency hopping resource is shifted and the original SRS frequency hopping resource after the shift operation is used as the target SRS frequency hopping resource.

[0082] In one example, when the total SRS frequency hopping bandwidth configuration is larger than the configured bandwidth of the uplink subband of the SBFD time-frequency resource, that is, the lowest PRB index of the transmission bandwidth of any SRS hop exceeds the lowest PRB index of the uplink subband, or the highest PRB index of the transmission bandwidth of any SRS hop exceeds the highest PRB index of the uplink subband, then the transmission bandwidth of the SRS hop is automatically shifted up or down by Δ, where Δ is the total number of PRBs exceeding the uplink subband. For example, assuming that the original SRS frequency hopping resource includes a first SRS frequency hopping resource and a second SRS frequency hopping resource, the original SRS frequency hopping resource is shifted, such as by Δ upward or downward, where Δ is the total number of PRBs occupied by the second SRS frequency hopping resource. If the lowest PRB index of the original SRS frequency hopping resource exceeds the lowest PRB index of the uplink subband, the original SRS frequency hopping resource can be shifted up; if the highest PRB index of the original SRS frequency hopping resource exceeds the highest PRB index of the uplink subband, the original SRS frequency hopping resource can be shifted down.

[0083] In this case, since the shift is upward or downward by a Δ, the total number of PRBs occupied by the original SRS frequency hopping resources and the target SRS frequency hopping resources is the same, that is, the transmit power of the UE remains unchanged.

[0084] In an example, if the PRB index of the starting position of the original SRS frequency hopping resource is smaller than the lowest PRB index of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource can be shifted upward in the frequency domain, and the original SRS frequency hopping resource after the upward shift operation is used as the target SRS frequency hopping resource. The PRB index of the starting position of the target SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, or the PRB index of the starting position of the target SRS frequency hopping resource is greater than the lowest PRB index of the uplink subband of the SBFD time-frequency resource.

[0085] Taking the example that the PRB index of the starting position of the target SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband, the original SRS frequency hopping resource is shifted upward by Δ in the frequency domain, and Δ is the total number of PRBs occupied by the second SRS frequency hopping resource, so that the PRB index of the starting position is equal to the lowest PRB index of the uplink subband.

[0086] In an example, if the PRB index of the end position of the original SRS frequency hopping resource is greater than the highest PRB index of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource can be shifted downward in the frequency domain, and the original SRS frequency hopping resource after the downward shift operation is used as the target SRS frequency hopping resource, and the PRB index of the end position of the target SRS frequency hopping resource is equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource, or, the PRB index of the end position of the target SRS frequency hopping resource is less than the highest PRB index of the uplink subband of the SBFD time-frequency resource.

[0087] Taking the example that the PRB index of the end position of the target SRS frequency hopping resource is equal to the highest PRB index of the uplink subband, the original SRS frequency hopping resource is shifted downward by Δ in the frequency domain, and Δ is the total number of PRBs occupied by the second SRS frequency hopping resource, so that the PRB index of the end position is equal to the highest PRB index of the uplink subband.

[0088] In one example, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources between time slots (Inter-slot); or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources within a time slot (Intra-slot); or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources with repeated transmission between time slots; or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources with repeated transmission within a time slot, and there is no restriction on this.

[0089] Referring to FIG3A , which is a schematic diagram of multiple original SRS frequency-hopping resources within a time slot, SBFD time-frequency resources can be configured in uplink subbands across four consecutive downlink time slots or F time slots. FIG3A illustrates a bandwidth shifting method for a two-hop scenario. When the two-hop SRS configuration exceeds the uplink subband, it is shifted upward or downward. For example, if the PRB index at the starting position of the first hop is less than the lowest PRB index of the uplink subband, the original SRS frequency-hopping resource of the first hop is shifted upward by Δ so that the PRB index at the starting position equals the lowest PRB index of the uplink subband. Referring to FIG3B , which is a schematic diagram of multiple target SRS frequency-hopping resources within a time slot, it can be seen that after the original SRS frequency-hopping resource of the first hop is shifted upward by Δ, the target SRS frequency-hopping resources of the first and second hops overlap, which does not affect the generation and transmit power of the SRS frequency-hopping signal for each hop, and more accurate channel state detection in the center region of the uplink subband is achieved.

[0090] See Figure 3C, which is a schematic diagram of multiple original SRS frequency hopping resources within a time slot. Figure 3C illustrates a bandwidth shifting method for a four-hop configuration. When the SRS four-hop configuration exceeds the uplink subband, it will be shifted upward or downward. For example, if the PRB index at the end position of the second hop is greater than the highest PRB index of the uplink subband, the original SRS frequency hopping resource of the second hop is shifted downward by Δ so that the PRB index at the end position equals the highest PRB index of the uplink subband. See Figure 3D, which is a schematic diagram of multiple target SRS frequency hopping resources within a time slot. As can be seen from Figure 3D, after the original SRS frequency hopping resource of the second hop is shifted downward by Δ, the target SRS frequency hopping resources of the second and third hops overlap.

[0091] In an example, the translation operation is only performed on the original SRS frequency hopping resources that exceed the uplink subband range, while the original SRS frequency hopping resources that do not exceed the uplink subband range are not shifted. As shown in Figure 3A, only the original SRS frequency hopping resources of the first hop that exceed the uplink subband range are shifted, and the original SRS frequency hopping resources of the second hop that do not exceed the uplink subband range are not shifted. As shown in Figure 3B, only the original SRS frequency hopping resources of the second hop that exceed the uplink subband range are shifted, and the original SRS frequency hopping resources of the first, third, and fourth hops that do not exceed the uplink subband range are not shifted.

[0092] Refer to Figure 3E, which is a schematic diagram of multiple original SRS frequency hopping resources between time slots. Figure 3E is a bandwidth shifting method for the 4-hop case. For example, the PRB index of the starting position of the 1st and 3rd hops is less than the lowest PRB index of the uplink subband. Therefore, the original SRS frequency hopping resources of the 1st and 3rd hops can be shifted upward by Δ so that the PRB index of the starting position is equal to the lowest PRB index of the uplink subband. Refer to Figure 3F, which is a schematic diagram of multiple target SRS frequency hopping resources between time slots.

[0093] FIG3G is a schematic diagram illustrating multiple original SRS frequency-hopping resources with repeated transmissions within a time slot. FIG3G illustrates a bandwidth shifting method for a two-hop scenario, where the SRS repeated transmission pattern is repeated transmission pattern 1 (1, 1, 2, 2, i.e., the first and second SRS hops are repeated transmissions, and the third and fourth SRS hops are repeated transmissions). When the two-hop SRS configuration exceeds the uplink subband, it is shifted upward or downward. For example, if the PRB index at the end position of the second hop is greater than the highest PRB index of the uplink subband, the original SRS frequency-hopping resource of the second hop is shifted downward by Δ so that the PRB index at the end position equals the highest PRB index of the uplink subband. FIG3H is a schematic diagram illustrating multiple target SRS frequency-hopping resources with repeated transmissions within a time slot. The bandwidth shifting method is applied to the original SRS frequency-hopping resources that exceed the uplink subband range, as well as the original SRS frequency-hopping resources with repeated transmissions following the original SRS frequency-hopping resources. For example, if the bandwidth of the second SRS hop exceeds the uplink subband range, the second hop and its repeated transmissions are shifted downward by Δ (the portion exceeding the bandwidth), that is, the SRS frequency hopping resources on the 3rd and 4th symbols.

[0094] See Figure 3I , which is a schematic diagram of multiple original SRS frequency-hopping resources with repeated transmissions within a time slot. Figure 3I illustrates a bandwidth shifting method for a two-hop scenario, where the SRS repeated transmission pattern is repeated transmission pattern 2 (1, 2, 1, 2, i.e., the first and third are repeated transmissions, and the second and fourth are repeated transmissions). For example, if the PRB index at the end position of the second hop is greater than the highest PRB index of the uplink subband, the original SRS frequency-hopping resource of the second hop is shifted downward by Δ so that the PRB index at the end position equals the highest PRB index of the uplink subband. See Figure 3J , which is a schematic diagram of multiple target SRS frequency-hopping resources with repeated transmissions within a time slot. The bandwidth shifting method is applied to original SRS frequency-hopping resources that exceed the uplink subband range, as well as to the original SRS frequency-hopping resources with repeated transmissions following the original SRS frequency-hopping resources. For example, if the bandwidth of the second SRS hop exceeds the uplink subband range, the second hop and its repeated transmissions are shifted downward by Δ (the portion exceeding the bandwidth), that is, the SRS frequency hopping resources on the 2nd and 4th symbols.

[0095] Method 16: If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, the original SRS frequency hopping resource includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then a cyclic shift operation is performed on the original SRS frequency hopping resource, and the original SRS frequency hopping resource after the cyclic shift operation is used as the target SRS frequency hopping resource.

[0096] For example, if the second SRS frequency hopping resource exceeds the lower boundary range of the uplink subband of the SBFD time-frequency resource, the second SRS frequency hopping resource is cyclically shifted to the upper boundary of the uplink subband to obtain a third SRS frequency hopping resource located in the uplink subband; or, if the second SRS frequency hopping resource exceeds the upper boundary range of the uplink subband of the SBFD time-frequency resource, the second SRS frequency hopping resource is cyclically shifted to the lower boundary of the uplink subband to obtain a third SRS frequency hopping resource located in the uplink subband; then, a target SRS frequency hopping resource is generated, and the target SRS frequency hopping resource includes the first SRS frequency hopping resource and the third SRS frequency hopping resource.

[0097] In an example, the entire bandwidth of the uplink subband of the SBFD time-frequency resource can be viewed as a ring. When the bandwidth of a certain SRS hop exceeds the bandwidth boundary of the uplink subband, the portion of the SRS frequency hopping resource that exceeds the bandwidth at one end will be reallocated to the corresponding bandwidth at the other end. In this way, even if the total bandwidth of the SRS frequency hopping transmission exceeds the uplink subband, the UE will not send the SRS frequency hopping signal outside the uplink subband, and the integrity of the SRS frequency hopping signal can be guaranteed, and the transmit power of the SRS frequency hopping signal can be kept unchanged.

[0098] In an example, if the PRB index of the starting position of the original SRS frequency hopping resource is less than the lowest PRB index of the uplink subband of the SBFD time-frequency resource, that is, the second SRS frequency hopping resource exceeds the lower boundary range of the uplink subband, then the second SRS frequency hopping resource is cyclically shifted to the upper boundary of the uplink subband to obtain a third SRS frequency hopping resource located in the uplink subband, that is, the third SRS frequency hopping resource is the SRS frequency hopping resource at the upper boundary.

[0099] Among them, after the second SRS frequency hopping resource is cyclically shifted to the upper boundary of the uplink subband to obtain the third SRS frequency hopping resource, the PRB index of the starting position of the first SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the ending position of the first SRS frequency hopping resource is less than the highest PRB index of the uplink subband of the SBFD time-frequency resource. The PRB index of the starting position of the third SRS frequency hopping resource is greater than the lowest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the ending position of the third SRS frequency hopping resource is equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource, or the PRB index of the ending position of the third SRS frequency hopping resource is less than the highest PRB index of the uplink subband of the SBFD time-frequency resource, taking the case where the PRB index of the ending position is equal to the highest PRB index of the uplink subband.

[0100] After obtaining the first SRS frequency hopping resource and the third SRS frequency hopping resource, the first SRS frequency hopping resource and the third SRS frequency hopping resource can be combined into a target SRS frequency hopping resource, that is, the target SRS frequency hopping resource includes two SRS frequency hopping resources, and the two SRS frequency hopping resources can be discontinuous SRS frequency hopping resources.

[0101] In an example, if the PRB index of the end position of the original SRS frequency hopping resource is greater than the highest PRB index of the uplink subband of the SBFD time-frequency resource, that is, the second SRS frequency hopping resource exceeds the upper boundary range of the uplink subband, then the second SRS frequency hopping resource is cyclically shifted to the lower boundary of the uplink subband to obtain a third SRS frequency hopping resource located in the uplink subband, that is, the third SRS frequency hopping resource is the SRS frequency hopping resource at the lower boundary.

[0102] In which, after the second SRS frequency hopping resource is cyclically shifted to the lower boundary of the uplink subband to obtain the third SRS frequency hopping resource, the PRB index of the end position of the first SRS frequency hopping resource is equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the starting position of the first SRS frequency hopping resource is greater than the lowest PRB index of the uplink subband of the SBFD time-frequency resource. The PRB index of the end position of the third SRS frequency hopping resource is less than the highest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the starting position of the third SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, or the PRB index of the starting position of the third SRS frequency hopping resource is greater than the lowest PRB index of the uplink subband of the SBFD time-frequency resource, taking the case where the PRB index of the starting position is equal to the lowest PRB index of the uplink subband.

[0103] After obtaining the first SRS frequency hopping resource and the third SRS frequency hopping resource, the first SRS frequency hopping resource and the third SRS frequency hopping resource can be combined into a target SRS frequency hopping resource, that is, the target SRS frequency hopping resource includes two SRS frequency hopping resources, and the two SRS frequency hopping resources can be discontinuous SRS frequency hopping resources.

[0104] In one example, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources between time slots (Inter-slot); or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources within a time slot (Intra-slot); or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources with repeated transmission between time slots; or, the multiple original SRS frequency hopping resources may be multiple original SRS frequency hopping resources with repeated transmission within a time slot, and there is no restriction on this.

[0105] Refer to Figure 4A, which is a schematic diagram of multiple original SRS frequency hopping resources within a time slot. Figure 4A is a bandwidth cyclic shift method for the 2-hop case. When the SRS two-hop configuration exceeds the uplink sub-band, a cyclic shift will be performed. For example, the PRB index of the end position of the second hop is greater than the highest PRB index of the uplink sub-band. Therefore, the original SRS frequency hopping resource of the second hop is cyclically shifted, and the excess part (i.e., the second SRS frequency hopping resource) is cyclically shifted to the lower boundary of the uplink sub-band (i.e., the excess part is located at the bottom of the uplink sub-band) to obtain a third SRS frequency hopping resource. The third SRS frequency hopping resource and the first SRS frequency hopping resource constitute the target SRS frequency hopping resource. Refer to Figure 4B, which is a schematic diagram of multiple target SRS frequency hopping resources within a time slot.

[0106] Refer to Figure 4C, which is a schematic diagram of multiple original SRS frequency hopping resources between time slots. The PRB index of the end position of the 2nd and 4th original SRS frequency hopping resources is greater than the highest PRB index of the uplink subband. The 2nd and 4th original SRS frequency hopping resources are cyclically shifted, and the excess part is cyclically shifted to the lower boundary to obtain the third SRS frequency hopping resource. The third SRS frequency hopping resource and the first SRS frequency hopping resource constitute the target SRS frequency hopping resource. Refer to Figure 4D, which is a schematic diagram of multiple target SRS frequency hopping resources between time slots.

[0107] Of course, if the PRB index of the starting position of the original SRS frequency hopping resource is less than the lowest PRB index of the uplink subband, the original SRS frequency hopping resource can be cyclically shifted, and the excess part can be cyclically shifted to the upper boundary (that is, the excess part is located at the top of the uplink subband). This process will not be described in detail.

[0108] See Figure 4E, which is a schematic diagram of multiple original SRS frequency-hopping resources with repeated transmissions within a time slot. Figure 4E illustrates a bandwidth cyclic shift method for a two-hop scenario, where the SRS repeated transmission pattern is repeated transmission pattern 1 (1, 1, 2, 2). The bandwidth cyclic shift method is applied to original SRS frequency-hopping resources that exceed the uplink subband range, as well as to the original SRS frequency-hopping resources for repeated transmissions following the original SRS frequency-hopping resources. For example, if the original SRS frequency-hopping resource for the second hop exceeds the upper boundary of the uplink subband, the original SRS frequency-hopping resources for the second hop and subsequent repeated transmissions are cyclically shifted to obtain a target SRS frequency-hopping resource within the uplink subband. See Figure 4F, which is a schematic diagram of multiple target SRS frequency-hopping resources.

[0109] Refer to Figure 4G, which is a schematic diagram of multiple original SRS frequency hopping resources with repeated transmission within a time slot, and the pattern of SRS repeated transmission is repeated transmission pattern 2 (i.e., repeated transmission of 1, 2, 1, 2). The original SRS frequency hopping resource of the second hop exceeds the upper boundary of the uplink subband. The original SRS frequency hopping resource of the second hop and subsequent repeated transmissions is cyclically shifted to obtain the target SRS frequency hopping resource located within the uplink subband. Refer to Figure 4H, which is a schematic diagram of multiple target SRS frequency hopping resources.

[0110] In an example, the base station can adopt scheme A to determine the first SRS frequency hopping resource set, or adopt scheme B to determine the first SRS frequency hopping resource set (such as adopting at least one of methods 11-16, for example, for each original SRS frequency hopping resource, a method can be used to determine the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource, and the methods corresponding to different original SRS frequency hopping resources can be the same or different). After obtaining the first SRS frequency hopping resource set, the base station can send first SRS frequency hopping transmission configuration information to the UE. The first SRS frequency hopping transmission configuration information is used to indicate the first SRS frequency hopping resource set, and the first SRS frequency hopping resource set includes multiple SRS frequency hopping resources, and each SRS frequency hopping resource can be located in the uplink subband of the SBFD time-frequency resource.

[0111] The UE may receive the first SRS frequency hopping transmission configuration information, determine the first SRS frequency hopping resource set based on the first SRS frequency hopping transmission configuration information, and send an SRS frequency hopping signal to the base station based on each SRS frequency hopping resource in the first SRS frequency hopping resource set. The base station receives the SRS frequency hopping signal sent by the UE.

[0112] In one example, for solution B, when configuring SRS frequency hopping resources, the base station does not need to ensure that each SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource. Instead, the configured SRS frequency hopping resources are referred to as original SRS frequency hopping resources, and all original SRS frequency hopping resources are grouped into a first SRS frequency hopping resource set. The base station then sends first SRS frequency hopping transmission configuration information to the UE, where the first SRS frequency hopping transmission configuration information is used to indicate the first SRS frequency hopping resource set. The UE may receive the first SRS frequency hopping transmission configuration information and determine the first SRS frequency hopping resource set based on the first SRS frequency hopping transmission configuration information.

[0113] After obtaining the first SRS frequency hopping resource set, the UE can obtain multiple original SRS frequency hopping resources from the first SRS frequency hopping resource set. For each original SRS frequency hopping resource, method 11-method 16 can be used to determine the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource, and the UE sends an SRS frequency hopping signal to the base station based on the target SRS frequency hopping resource, and the base station receives the SRS frequency hopping signal sent by the UE.

[0114] Case 2: For non-SBFD time slots or non-SBFD symbols (such as uplink time slots or uplink symbols), the base station configures an SRS frequency hopping resource set for the UE, and this SRS frequency hopping resource set is called the second SRS frequency hopping resource set. The second SRS frequency hopping resource set includes SRS frequency hopping resources located in the uplink time slot or uplink symbol.

[0115] In one example, SRS frequency hopping resources can be configured in an uplink time slot or uplink symbol, that is, each SRS frequency hopping resource in the second SRS frequency hopping resource set is located in an uplink time slot or uplink symbol. After multiple SRS frequency hopping resources are configured in the uplink time slot or uplink symbol, the multiple SRS frequency hopping resources can be combined into a second SRS frequency hopping resource set. With respect to the multiple SRS frequency hopping resources in the second SRS frequency hopping resource set, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources between time slots (inter-slot); or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources within a time slot (intra-slot); or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources with repeated transmission between time slots; or, the multiple SRS frequency hopping resources can be multiple SRS frequency hopping resources with repeated transmission within a time slot.

[0116] In one example, the base station may send second SRS frequency hopping transmission configuration information to the UE, where the second SRS frequency hopping transmission configuration information is used to indicate a second SRS frequency hopping resource set, and the second SRS frequency hopping resource set includes multiple SRS frequency hopping resources, each of which may be located in an uplink time slot or an uplink symbol.

[0117] The UE can receive the second SRS frequency hopping transmission configuration information, determine the second SRS frequency hopping resource set based on the second SRS frequency hopping transmission configuration information, and send an SRS frequency hopping signal to the base station based on each SRS frequency hopping resource in the second SRS frequency hopping resource set. The base station receives the SRS frequency hopping signal sent by the UE.

[0118] In an example, for Case 1 and Case 2, the first SRS frequency hopping transmission configuration information and the second SRS frequency hopping transmission configuration information can be sent separately or simultaneously, and the sending manner can be flexibly set.

[0119] The first SRS frequency hopping transmission configuration information may be dynamic resource configuration information or semi-static resource configuration information, and the second SRS frequency hopping transmission configuration information may be dynamic resource configuration information or semi-static resource configuration information.

[0120] Case 3: For SBFD time slots or SBFD symbols, and non-SBFD time slots or non-SBFD symbols (e.g., uplink time slots or uplink symbols), the base station configures a unified SRS frequency hopping resource set for the UE. This SRS frequency hopping resource set may be referred to as a third SRS frequency hopping resource set. The third SRS frequency hopping resource set may include SRS frequency hopping resources located in an uplink subband of the SBFD time-frequency resources, and / or the third SRS frequency hopping resource set may include SRS frequency hopping resources located in an uplink time slot or uplink symbol.

[0121] In one example, an uplink subband of an SBFD time-frequency resource can be configured in a downlink time slot, downlink symbol, F time slot, or F symbol, and an SRS frequency hopping resource can be configured in an uplink subband of the SBFD time-frequency resource. SRS frequency hopping resources can be configured in an uplink time slot or uplink symbol. When a unified third SRS frequency hopping resource set is configured for a UE, the SRS frequency hopping resource can be located in an uplink subband of the SBFD time-frequency resource, or in an uplink time slot or uplink symbol.

[0122] After the base station configures the SRS frequency hopping resources, the configured SRS frequency hopping resources are called original SRS frequency hopping resources (also called SRS frequency hopping resource configuration). Then, by optimizing the original SRS frequency hopping resources, target SRS frequency hopping resources that meet the requirements are obtained. In this way, the target SRS frequency hopping resources corresponding to all original SRS frequency hopping resources can be combined into a third SRS frequency hopping resource set.

[0123] In one example, if the original SRS frequency hopping resource is located in an uplink time slot or uplink symbol, the target SRS frequency hopping resource is determined based on the original SRS frequency hopping resource, and the target SRS frequency hopping resource does not overlap with the downlink subband of the SBFD time-frequency resource. Alternatively, if the original SRS frequency hopping resource is located in a downlink time slot, downlink symbol, F time slot, or F symbol, and there is an uplink subband of the SBFD time-frequency resource, the target SRS frequency hopping resource is determined based on the overlap between the original SRS frequency hopping resource and the uplink subband of the SBFD time-frequency resource.

[0124] In an example, for each original SRS frequency hopping resource, taking an original SRS frequency hopping resource as an example, the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource may be determined in the following manner:

[0125] Method 21: If the original SRS frequency hopping resource is located in an uplink time slot or uplink symbol, and the uplink time slot or uplink symbol does not have a downlink subband (UL subband) and a protection subband of the SBFD time-frequency resource, that is, the downlink subband and the protection subband are not configured in the uplink time slot or uplink symbol, then the original SRS frequency hopping resource is used as the target SRS frequency hopping resource.

[0126] Method 22: If the original SRS frequency hopping resource is located in the uplink time slot or uplink symbol, and the uplink time slot or uplink symbol has a downlink subband and / or protection subband of the SBFD time-frequency resource, that is, the uplink time slot or uplink symbol is configured with a downlink subband and / or protection subband, but the original SRS frequency hopping resource does not overlap with the downlink subband and / or protection subband of the SBFD time-frequency resource, then the original SRS frequency hopping resource can be used as the target SRS frequency hopping resource. Among them, the original SRS frequency hopping resource does not overlap with the downlink subband and / or protection subband means: if there is a downlink subband in the uplink time slot or uplink symbol, the original SRS frequency hopping resource does not overlap with the downlink subband; if there is a protection subband in the uplink time slot or uplink symbol, the original SRS frequency hopping resource does not overlap with the protection subband; if there is a downlink subband and a protection subband in the uplink time slot or uplink symbol, the original SRS frequency hopping resource does not overlap with the downlink subband, and the original SRS frequency hopping resource does not overlap with the protection subband.

[0127] In one example, the downlink subband and / or protection subband of the SBFD time-frequency resource can be configured in the uplink time slot or uplink symbol, and the original SRS frequency hopping resource cannot overlap with the downlink subband and / or protection subband of the SBFD time-frequency resource. Therefore, the overlap of the original SRS frequency hopping resource with the downlink subband and / or protection subband also needs to be considered. If the original SRS frequency hopping resource does not overlap with the downlink subband and / or protection subband, the original SRS frequency hopping resource can be used as the target SRS frequency hopping resource.

[0128] Method 23: If the original SRS frequency hopping resource is located in an uplink time slot or uplink symbol, and the uplink time slot or uplink symbol contains a downlink subband and / or protection subband of the SBFD time-frequency resource, then the discontinuous resources other than the downlink subband and / or protection subband of the SBFD time-frequency resource can be cascaded to obtain a cascaded resource set, that is, the cascaded resource set includes discontinuous resources other than the downlink subband and / or protection subband of the SBFD time-frequency resource, and the original SRS frequency hopping resource is only allowed to be configured in the cascaded resource set. In this way, the original SRS frequency hopping resource can be used as the target SRS frequency hopping resource.

[0129] For example, if the downlink subband and / or protection subband of the SBFD time-frequency resource is configured in the uplink time slot or uplink symbol, and the original SRS frequency hopping resource is located in the uplink time slot or uplink symbol, then the original SRS frequency hopping resource may fall in the downlink subband and / or protection subband of the SBFD time-frequency resource, resulting in the inability to normally send the SRS frequency hopping signal. See Figure 5A, which is a schematic diagram of the overlap of the original SRS frequency hopping resource and the downlink subband of the SBFD time-frequency resource. Obviously, the second and third original SRS frequency hopping resources overlap with the downlink subband of the SBFD time-frequency resource.

[0130] In order to avoid the overlap of the original SRS frequency hopping resources and the downlink subband and / or protection subband of the SBFD time-frequency resources, a cascade resource set can be used to cascade discontinuous resources other than the downlink subband and / or protection subband of the SBFD time-frequency resources (such as resources located on the upper side of the downlink subband and / or protection subband, and resources located on the lower side of the downlink subband and / or protection subband) to obtain a cascade resource set. See Figure 5B, which is a schematic diagram of a cascade resource set. The cascade resource set includes resources located on the upper side of the downlink subband and resources located on the lower side of the downlink subband. After obtaining the cascade resource set, only the original SRS frequency hopping resources are allowed to be configured in the cascade resource set, so that the original SRS frequency hopping resources do not overlap with the downlink subband and / or protection subband. The bandwidth of the SRS frequency hopping resources becomes smaller, which potentially increases the transmit power spectrum density (PSD) of the SRS.

[0131] In summary, a cascade resource set is obtained by cascading discontinuous resources outside the downlink subband and / or protection subband, and only the original SRS frequency hopping resources are allowed to be configured in the cascade resource set, so that the original SRS frequency hopping resources do not overlap with the downlink subband and / or protection subband.

[0132] As shown in Figure 5B, the cascaded resource set includes resources located on the upper side of the downlink subband (denoted as resource a1) and resources located on the lower side of the downlink subband (denoted as resource a2). Resource a1 and resource a2 are two non-continuous resources. Both the base station and the UE can cascade resource a1 and resource a2, that is, eliminate the resources of the downlink subband to obtain a continuous resource. The continuous resource includes resource a1 and resource a2. In this way, the UE can send an SRS frequency hopping signal to the base station based on the continuous resource.

[0133] The base station and the UE may pre-configure a resource concatenation indication, which indicates whether to perform resource concatenation. Alternatively, the base station may send a resource concatenation indication to the UE, which indicates whether to perform resource concatenation. If the resource concatenation indication indicates that resource concatenation is to be performed, the UE may concatenate two non-contiguous resources to obtain a contiguous resource and send an SRS frequency hopping signal to the base station based on the contiguous resource.

[0134] For example, assuming that resource a1 includes the 21st to 40th PRBs and resource a2 includes the 61st to 80th PRBs, then by cascading resource a1 and resource a2 to obtain a cascaded resource set, the UE can send SRS frequency hopping signals to the base station through the 21st to 40th PRBs and the 61st to 80th PRBs.

[0135] Method 24. If the original SRS frequency hopping resource is located in the uplink time slot or uplink symbol, and the uplink time slot or uplink symbol has a downlink subband and / or a protection subband of the SBFD time-frequency resource, then, if the original SRS frequency hopping resource coincides with the downlink subband and / or the protection subband of the SBFD time-frequency resource (if the uplink time slot or uplink symbol has a downlink subband, the original SRS frequency hopping resource coincides with the downlink subband; if the uplink time slot or uplink symbol has a protection subband, the original SRS frequency hopping resource coincides with the protection subband; if the uplink time slot or uplink symbol has a downlink subband and a protection subband, the original SRS frequency hopping resource coincides with the downlink subband, or the original SRS frequency hopping resource coincides with the protection subband), then the original SRS frequency hopping resource can be directly used as the target SRS frequency hopping resource.

[0136] Alternatively, if the original SRS frequency hopping resource overlaps with the downlink subband and / or protection subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is cancelled, ie, there is no target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource.

[0137] Alternatively, if the original SRS frequency hopping resources coincide with the downlink subband and / or protection subband of the SBFD time-frequency resources, assuming that the original SRS frequency hopping resources include a first part of resources and a second part of resources, the first part of resources coincides with the downlink subband of the SBFD time-frequency resources, and the second part of resources does not coincide with the downlink subband of the SBFD time-frequency resources, then the second part of resources can be used as the target SRS frequency hopping resources, but the first part of resources is not used as the target SRS frequency hopping resources, that is, the target SRS frequency hopping resources only include the second part of resources.

[0138] Alternatively, if the original SRS frequency hopping resource overlaps with the downlink subband and / or protection subband of the SBFD time-frequency resource, the original SRS frequency hopping resource may be shifted and the shifted original SRS frequency hopping resource may be used as the target SRS frequency hopping resource.

[0139] In an example, if an SRS is configured across SBFD time slots / SBFD symbols or non-SBFD time slots / non-SBFD symbols (inter-time slot hopping scheme), when any hop of the SRS exceeds the uplink subband of the SBFD time-frequency resource (for downlink time slots, downlink symbols, F time slots, F symbols), or falls within the downlink subband (for uplink time slots, uplink symbols), the hopped SRS frequency hopping resource can be shifted forward or backward to the nearest normal uplink time slot or uplink symbol (with or without SRS). There are two shifting methods:

[0140] The first is partial shifting, which shifts the portion of the SRS signal that exceeds the uplink subband (for downlink timeslots, downlink symbols, F timeslots, and F symbols) or falls within the downlink subband (for uplink timeslots and uplink symbols) to a normal uplink timeslot or uplink symbol. The second is full shifting, which shifts the entire SRS signal to a normal uplink timeslot or uplink symbol if all or part of any SRS hop exceeds the uplink subband (for downlink timeslots, downlink symbols, F timeslots, and F symbols) or falls within the downlink subband (for uplink timeslots and uplink symbols).

[0141] Among them, this translation may be forward or backward, depending on the overlapping position of the SRS frequency hopping resource and the ordinary uplink time slot or uplink symbol (for example, when the position of the front ordinary uplink time slot or uplink symbol is closer to the position of the SRS frequency hopping resource, it is translated forward, and when the position of the rear ordinary uplink time slot or uplink symbol is closer to the position of the SRS frequency hopping resource, it is translated backward), and the interval of the translation position needs to be guaranteed to configure sufficient preparation time for the UE. Of course, the above method may reduce the SRS transmission power spectral density PSD.

[0142] In one example, for all shifts, the original SRS frequency hopping resources may be shifted forward or backward in the time domain to available uplink time slots or uplink symbols, and the original SRS frequency hopping resources after the shift operation may be used as target SRS frequency hopping resources.

[0143] Referring to FIG5C , which is a schematic diagram of the shifting operation on the original SRS frequency hopping resource, the second original SRS frequency hopping resource overlaps (partially or completely) with the downlink sub-band of the SBFD time-frequency resource. Therefore, the second original SRS frequency hopping resource is shifted as a whole to the uplink symbol of the first hop of the SRS.

[0144] In an example, for partial shift, assuming that the original SRS frequency hopping resources include a first part of resources and a second part of resources, the first part of resources can be shifted forward or backward in the time domain to an available uplink time slot or uplink symbol, and the first part of resources after the shift operation is used as the third part of resources, and the position of the second part of resources remains unchanged. Then, the target SRS frequency hopping resources are generated, which may include the third part of resources and the second part of resources.

[0145] Refer to Figure 5C, which is a schematic diagram of the shift operation on the original SRS frequency hopping resources. The third original SRS frequency hopping resource overlaps with the downlink sub-band of the SBFD time-frequency resource (i.e., partially overlaps), and the original SRS frequency hopping resource includes a first part of the resources and a second part of the resources. Therefore, the first part of the resources of the third original SRS frequency hopping resource can be shifted to the uplink symbol of the first hop of the SRS.

[0146] Regarding whether to shift the original SRS frequency hopping resource forward or backward, find the first usable uplink time slot or uplink symbol in front of the original SRS frequency hopping resource, the target resource of the uplink time slot or uplink symbol is not occupied (that is, it is not occupied by the downlink subband or other data, and it is a usable resource), and the frequency domain position of the target resource is the same as the frequency domain position of the original SRS frequency hopping resource, and find the first usable uplink time slot or uplink symbol from behind the original SRS frequency hopping resource, the target resource of the uplink time slot or uplink symbol is not occupied, and the frequency domain position of the target resource is the same as the frequency domain position of the original SRS frequency hopping resource. If the interval between the previously available uplink time slot or uplink symbol and the original SRS frequency hopping resource is smaller, the original SRS frequency hopping resource is shifted forward to the first previously available uplink time slot or uplink symbol. If the interval between the subsequently available uplink time slot or uplink symbol and the original SRS frequency hopping resource is smaller, the original SRS frequency hopping resource is shifted backward to the first subsequently available uplink time slot or uplink symbol.

[0147] Method 25: If the original SRS frequency hopping resource is located in a downlink time slot, downlink symbol, F time slot or F symbol, and the downlink time slot, downlink symbol, F time slot or F symbol has an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource (i.e., does not exceed the uplink subband range), the original SRS frequency hopping resource can be used as the target SRS frequency hopping resource.

[0148] For example, when the base station configures the original SRS frequency hopping resource, it ensures that the original SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource, such as the PRB index of the starting position of the original SRS frequency hopping resource is greater than or equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, the PRB index of the starting position of the original SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the end position of the original SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource. Based on this, the original SRS frequency hopping resource is used as the target SRS frequency hopping resource.

[0149] Method 26: If the original SRS frequency hopping resource is located in a downlink time slot, downlink symbol, F time slot or F symbol, and there is an uplink subband of the SBFD time-frequency resource, then when the base station configures the SRS frequency hopping resource, it is not necessary to ensure that each SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource. However, if the original SRS frequency hopping resource is still located in the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource can be used as the target SRS frequency hopping resource.

[0150] Method 27: If the original SRS frequency hopping resource is located in a downlink time slot, downlink symbol, F time slot or F symbol, and there is an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is canceled, that is, there is no target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource.

[0151] Method 28: If the original SRS frequency hopping resource is located in a downlink time slot, downlink symbol, F time slot or F symbol, and there is an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource will be used as the target SRS frequency hopping resource. That is, even if the original SRS frequency hopping resource exceeds the range of the uplink subband, the original SRS frequency hopping resource will be used as the target SRS frequency hopping resource.

[0152] For example, assuming that the original SRS frequency hopping resource includes a first SRS frequency hopping resource and a second SRS frequency hopping resource, the first SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource, and the second SRS frequency hopping resource exceeds the uplink subband range of the SBFD time-frequency resource, then the first SRS frequency hopping resource and the second SRS frequency hopping resource are used as target SRS frequency hopping resources.

[0153] Method 29: If the original SRS frequency hopping resource is located in a downlink time slot, a downlink symbol, an F time slot or an F symbol, and there is an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, the original SRS frequency hopping resource includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then the first SRS frequency hopping resource is used as the target SRS frequency hopping resource, but the second SRS frequency hopping resource is not used as the target SRS frequency hopping resource.

[0154] Method 30: If the original SRS frequency hopping resource is located in a downlink time slot, a downlink symbol, an F time slot or an F symbol, and there is an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, the original SRS frequency hopping resource includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then the original SRS frequency hopping resource is shifted, and the original SRS frequency hopping resource after the shift operation is used as the target SRS frequency hopping resource.

[0155] Method 31: If the original SRS frequency hopping resource is located in a downlink time slot, a downlink symbol, an F time slot or an F symbol, and there is an uplink subband of the SBFD time-frequency resource, then if the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, that is, the original SRS frequency hopping resource includes the first SRS frequency hopping resource and the second SRS frequency hopping resource, then a cyclic shift operation is performed on the original SRS frequency hopping resource, and the original SRS frequency hopping resource after the cyclic shift operation is used as the target SRS frequency hopping resource.

[0156] The implementation process of method 31 is similar to that of method 16 and will not be repeated here.

[0157] For method 30, when performing a shift operation on the original SRS frequency hopping resource, an upward shift operation is performed on the original SRS frequency hopping resource in the frequency domain, and the original SRS frequency hopping resource after the upward shift operation is used as the target SRS frequency hopping resource, or a downward shift operation is performed on the original SRS frequency hopping resource in the frequency domain, and the original SRS frequency hopping resource after the downward shift operation is used as the target SRS frequency hopping resource. For the implementation process, please refer to method 15.

[0158] With respect to method 30, when performing a shift operation on the original SRS frequency hopping resource, the original SRS frequency hopping resource may be shifted forward or backward in the time domain to an available uplink time slot or uplink symbol, and the original SRS frequency hopping resource after the shift operation may be used as the target SRS frequency hopping resource (see full shift in method 24). Alternatively, the original SRS frequency hopping resource includes a first SRS frequency hopping resource and a second SRS frequency hopping resource, and the second SRS frequency hopping resource may be shifted forward or backward in the time domain to an available uplink time slot or uplink symbol, and the original second SRS frequency hopping resource after the shift operation may be used as the third SRS frequency hopping resource, thereby generating a target SRS frequency hopping resource, wherein the target SRS frequency hopping resource includes the first SRS frequency hopping resource and the third SRS frequency hopping resource (see partial shift in method 24).

[0159] Referring to Figure 5D , which illustrates a full shift, in the first transmission, the second original SRS frequency-hopping resource exceeds the uplink subband range of the SBFD time-frequency resource, and the second original SRS frequency-hopping resource is shifted entirely to the uplink symbol of the first SRS hop. In the second transmission, the first original SRS frequency-hopping resource exceeds the uplink subband range of the SBFD time-frequency resource, and the first original SRS frequency-hopping resource is shifted entirely to the uplink symbol of the second SRS hop.

[0160] Referring to Figure 5E , which illustrates a partial shift, in the first transmission, the second original SRS frequency-hopping resource exceeds the uplink subband range of the SBFD time-frequency resources, and the second SRS frequency-hopping resource of the second original SRS frequency-hopping resource is shifted to the uplink symbol of the first SRS hop. In the second transmission, the first original SRS frequency-hopping resource entirely exceeds the uplink subband range of the SBFD time-frequency resources, and the first original SRS frequency-hopping resource is shifted entirely to the uplink symbol of the second SRS hop.

[0161] In one example, the base station may adopt at least one of methods 21 to 31. For example, for each original SRS frequency hopping resource, a method may be used to determine the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource. The methods corresponding to different original SRS frequency hopping resources may be the same or different. After obtaining the target SRS frequency hopping resources corresponding to all original SRS frequency hopping resources, all target SRS frequency hopping resources may be grouped into a third SRS frequency hopping resource set. Then, the base station may send third SRS frequency hopping transmission configuration information to the UE. The third SRS frequency hopping transmission configuration information is used to indicate a third SRS frequency hopping resource set, and the third SRS frequency hopping resource set includes multiple SRS frequency hopping resources. Each SRS frequency hopping resource may be located in an uplink subband of the SBFD time-frequency resource, or in an uplink time slot or uplink symbol.

[0162] In one example, the multiple SRS frequency hopping resources in the third SRS frequency hopping resource set are multiple SRS frequency hopping resources between time slots; or, the multiple SRS frequency hopping resources are multiple SRS frequency hopping resources within a time slot; or, the multiple SRS frequency hopping resources are multiple SRS frequency hopping resources with repeated transmission between time slots; or, the multiple SRS frequency hopping resources are multiple SRS frequency hopping resources with repeated transmission within a time slot.

[0163] The UE can receive the third SRS frequency hopping transmission configuration information, determine the third SRS frequency hopping resource set based on the third SRS frequency hopping transmission configuration information, and send an SRS frequency hopping signal to the base station based on each SRS frequency hopping resource in the third SRS frequency hopping resource set. The base station receives the SRS frequency hopping signal sent by the UE.

[0164] In one example, when configuring SRS frequency hopping resources, the base station may refer to the configured SRS frequency hopping resources as original SRS frequency hopping resources, group all original SRS frequency hopping resources into a third SRS frequency hopping resource set, and send third SRS frequency hopping transmission configuration information to the UE. The third SRS frequency hopping transmission configuration information is used to indicate the third SRS frequency hopping resource set. The UE may receive the third SRS frequency hopping transmission configuration information and determine the third SRS frequency hopping resource set based on the third SRS frequency hopping transmission configuration information.

[0165] After obtaining the third SRS frequency hopping resource set, the UE can obtain multiple original SRS frequency hopping resources from the third SRS frequency hopping resource set. For each original SRS frequency hopping resource, method 21-method 31 can be used to determine the target SRS frequency hopping resource corresponding to the original SRS frequency hopping resource, and the UE sends an SRS frequency hopping signal to the base station based on the target SRS frequency hopping resource, and the base station receives the SRS frequency hopping signal sent by the UE.

[0166] In an example, the third SRS frequency hopping transmission configuration information may be resource configuration information in a dynamic manner or in a semi-static manner, and there is no limitation on this.

[0167] Based on the same inventive concept, an SRS frequency hopping signal transmission device corresponding to the above-mentioned SRS frequency hopping signal transmission method, as well as a base station and a UE are also provided. Since the principles of solving the problems by the base station and the UE are similar to those of the SRS frequency hopping signal transmission method, the implementation of the base station and the UE can refer to the implementation of the SRS frequency hopping signal transmission method, and the repeated parts will not be repeated.

[0168] Based on the same application concept as the above method, this application proposes an SRS frequency hopping signal transmission device as an example, which is applied to a user equipment, as shown in FIG6A , and includes:

[0169] The receiving module 611 is configured to receive SRS frequency hopping transmission configuration information sent by a base station, where the SRS frequency hopping transmission configuration information is used to indicate an SRS frequency hopping resource set, where the SRS frequency hopping resource set includes multiple SRS frequency hopping resources.

[0170] a sending module 612, configured to send an SRS frequency hopping signal to a base station based on each SRS frequency hopping resource in the SRS frequency hopping resource set;

[0171] For each SRS frequency hopping resource, the SRS frequency hopping resource is located in an uplink time slot or an uplink symbol, or the SRS frequency hopping resource is located in an uplink subband of an SBFD time-frequency resource.

[0172] In one example, the SRS frequency hopping transmission configuration information includes first SRS frequency hopping transmission configuration information and second SRS frequency hopping transmission configuration information; the first SRS frequency hopping transmission configuration information is used to indicate a first SRS frequency hopping resource set, and the first SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink subband of an SBFD time-frequency resource; the second SRS frequency hopping transmission configuration information is used to indicate a second SRS frequency hopping resource set, and the second SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink time slot or an uplink symbol;

[0173] Alternatively, the SRS frequency hopping transmission configuration information includes third SRS frequency hopping transmission configuration information, where the third SRS frequency hopping transmission configuration information is used to indicate a third SRS frequency hopping resource set, where the third SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink subband of an SBFD time-frequency resource, and / or an SRS frequency hopping resource located in an uplink time slot or uplink symbol;

[0174] The SBFD time-frequency resource is located in a downlink time slot or a downlink symbol, or the SBFD time-frequency resource is located in an F time slot or an F symbol.

[0175] Based on the same application concept as the above method, this application proposes an SRS frequency hopping signal transmission device as an example, which is applied to a base station, as shown in FIG6B . The device includes:

[0176] a sending module 621, configured to send SRS frequency hopping transmission configuration information to a user equipment, where the SRS frequency hopping transmission configuration information is used to indicate an SRS frequency hopping resource set, and the SRS frequency hopping resource set includes multiple SRS frequency hopping resources;

[0177] The receiving module 622 is configured to receive an SRS frequency hopping signal sent by the user equipment to the base station based on the SRS frequency hopping resource;

[0178] For each SRS frequency hopping resource, the SRS frequency hopping resource is located in an uplink time slot or an uplink symbol; or, the SRS frequency hopping resource is located in an uplink subband of an SBFD time-frequency resource.

[0179] In one example, the SRS frequency hopping transmission configuration information includes first SRS frequency hopping transmission configuration information and second SRS frequency hopping transmission configuration information; the first SRS frequency hopping transmission configuration information is used to indicate a first SRS frequency hopping resource set, and the first SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink subband of an SBFD time-frequency resource; the second SRS frequency hopping transmission configuration information is used to indicate a second SRS frequency hopping resource set, and the second SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink time slot or an uplink symbol;

[0180] Alternatively, the SRS frequency hopping transmission configuration information includes third SRS frequency hopping transmission configuration information, where the third SRS frequency hopping transmission configuration information is used to indicate a third SRS frequency hopping resource set, where the third SRS frequency hopping resource set includes an SRS frequency hopping resource located in an uplink subband of an SBFD time-frequency resource, and / or an SRS frequency hopping resource located in an uplink time slot or uplink symbol;

[0181] The SBFD time-frequency resource is located in a downlink time slot or a downlink symbol, or the SBFD time-frequency resource is located in an F time slot or an F symbol.

[0182] In one example, the apparatus further comprises (not shown in FIG6B ):

[0183] A processing module is used to configure multiple SRS frequency hopping resources for the user equipment, where the starting position and the ending position of each SRS frequency hopping resource are both located in the uplink subband of the SBFD time-frequency resource; and generate a first SRS frequency hopping resource set, where the first SRS frequency hopping resource set includes the multiple SRS frequency hopping resources.

[0184] In one example, the starting position and the ending position of the SRS frequency hopping resource are both located within the uplink subband of the SBFD time-frequency resource, including:

[0185] The PRB index of the starting position of the SRS frequency hopping resource is greater than or equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource, and the PRB index of the starting position of the SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource;

[0186] The PRB index of the end position of the SRS frequency hopping resource is less than or equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource.

[0187] In one example, the processing module is configured to configure a plurality of original SRS frequency hopping resources for the user equipment;

[0188] If the original SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is used as the target SRS frequency hopping resource;

[0189] If the original SRS frequency hopping resource exceeds the range of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource includes a first SRS frequency hopping resource and a second SRS frequency hopping resource, the first SRS frequency hopping resource is located in the uplink subband of the SBFD time-frequency resource, and the second SRS frequency hopping resource exceeds the uplink subband range of the SBFD time-frequency resource, then:

[0190] canceling the original SRS frequency hopping resource; or,

[0191] Using the first SRS frequency hopping resource as the target SRS frequency hopping resource; or,

[0192] Using the first SRS frequency hopping resource and the second SRS frequency hopping resource as the target SRS frequency hopping resource; or,

[0193] Performing a translation operation or a cyclic shift operation on the original SRS frequency hopping resource, and using the original SRS frequency hopping resource after the translation operation or the cyclic shift operation as the target SRS frequency hopping resource;

[0194] A first SRS frequency hopping resource set is generated, where the first SRS frequency hopping resource set includes target SRS frequency hopping resources corresponding to the multiple original SRS frequency hopping resources.

[0195] In one example, when the processing module performs a shift operation on the original SRS frequency hopping resource, it is specifically used to: if the PRB index of the starting position of the original SRS frequency hopping resource is less than the lowest PRB index of the uplink subband of the SBFD time-frequency resource, then perform an upward shift operation in the frequency domain on the original SRS frequency hopping resource, and use the original SRS frequency hopping resource after the upward shift operation as the target SRS frequency hopping resource, and the PRB index of the starting position of the target SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource; or,

[0196] If the PRB index of the end position of the original SRS frequency hopping resource is greater than the highest PRB index of the uplink subband of the SBFD time-frequency resource, the original SRS frequency hopping resource is subjected to a downward shift in the frequency domain, and the original SRS frequency hopping resource after the downward shift operation is used as the target SRS frequency hopping resource, and the PRB index of the end position of the target SRS frequency hopping resource is equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource.

[0197] In one example, the processing module is specifically configured to perform a cyclic shift operation on the original SRS frequency hopping resource: if the second SRS frequency hopping resource exceeds the lower boundary range of the uplink subband of the SBFD time-frequency resource, cyclically shift the second SRS frequency hopping resource to the upper boundary of the uplink subband to obtain a third SRS frequency hopping resource located within the uplink subband; or, if the second SRS frequency hopping resource exceeds the upper boundary range of the uplink subband of the SBFD time-frequency resource, cyclically shift the second SRS frequency hopping resource to the lower boundary of the uplink subband to obtain a third SRS frequency hopping resource located within the uplink subband;

[0198] A target SRS frequency hopping resource is generated, where the target SRS frequency hopping resource includes the first SRS frequency hopping resource and the third SRS frequency hopping resource.

[0199] In one example, when the processing module cyclically shifts the second SRS frequency hopping resource to the upper boundary of the uplink subband to obtain the third SRS frequency hopping resource located in the uplink subband, the PRB index of the end position of the third SRS frequency hopping resource is equal to the highest PRB index of the uplink subband of the SBFD time-frequency resource; when the processing module cyclically shifts the second SRS frequency hopping resource to the lower boundary of the uplink subband to obtain the third SRS frequency hopping resource located in the uplink subband, the PRB index of the starting position of the third SRS frequency hopping resource is equal to the lowest PRB index of the uplink subband of the SBFD time-frequency resource.

[0200] In one example, the processing module is configured to configure a plurality of original SRS frequency hopping resources for the user equipment;
