Description

Uplink signal frequency hopping transmission method, terminal and network side device Cross-reference The present application claims priority to the Chinese patent application No. 2024106267109, filed on May 20, 2024, and entitled "Uplink signal frequency hopping transmission method, terminal and network side device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present application belongs to the field of communication technology, and specifically relates to an uplink signal frequency hopping transmission method, a terminal and a network side device. BACKGROUND Large bandwidth is a key driving factor for ultra-high data rate transmission. For downlink transmission, one component carrier (CC) or one bandwidth part (BWP) may support a very large bandwidth such as 800M in the future; but for uplink transmission, due to different terminal transceiver capabilities and different service requirements, it is not possible to support larger bandwidth transmission like downlink transmission, such as only supporting 200M or 100M. In a time division duplex (TDD) system, in order to realize channel reciprocity, some uplink signals (such as sounding reference signals SRS) can be used for uplink channel measurement, and the downlink channel state information (CSI) can be calculated by using channel reciprocity. In a large bandwidth scenario, due to different terminal transceiver capabilities and different service requirements, the terminal cannot determine how to transmit uplink signals, and thus cannot obtain downlink CSI by using channel reciprocity through uplink signals, resulting in that channel estimation cannot be performed in a large bandwidth scenario, and communication performance is affected.

The uplink signal frequency hopping transmission method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, some embodiments and application scenarios. As shown in FIG. 2, the embodiments of the present application provide an uplink signal frequency hopping transmission method 200, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal, and the method comprises the following steps. S202: The terminal receives frequency hopping configuration information, wherein the frequency hopping configuration information comprises information indicating a first BWP. In this embodiment, the frequency hopping configuration information can comprise a frequency range of the first BWP, and the first BWP is configured with multiple hops. The frequency hopping configuration information can further comprise at least one of the following information: an index of each hop, a number of hops, a bandwidth of each hop, a frequency domain starting position of each hop, a frequency domain starting position of the first hop or the hop with the lowest frequency domain position, a time domain position of each hop, a time domain position of the first hop, and a bandwidth of the overlapping of adjacent hops. S204: The terminal performs frequency hopping transmission of the uplink signal in the first BWP, wherein the frequency range of the first BWP exceeds the maximum bandwidth capability of the terminal, and the first BWP is configured with multiple hops. As shown in FIG. 3, the terminal performs frequency hopping transmission of the uplink signal in the first BWP, wherein the frequency range of the first BWP exceeds the maximum bandwidth capability of the terminal, and the first BWP is configured with multiple hops, such as SRS hop 0, SRS hop 1, SRS hop 2 and SRS hop 3 shown in FIG. 3. The number of hops configured in the first BWP is not limited to 4 hops in FIG. 3. In one example, in the case that the bandwidth of the activated uplink BWP does not exceed the maximum bandwidth capability of the terminal, and the frequency hopping transmission of the uplink signal exceeds the range of the activated uplink BWP, the frequency range of the first BWP exceeds the frequency range of the activated uplink BWP. Optionally, the first BWP comprises the activated uplink BWP and a second BWP, which can be referred to as a “virtual BWP”. The “virtual BWP” is only used for frequency domain position reference of multiple hops. Optionally, the virtual BWP can also be replaced by other descriptions, such as virtual frequency band, virtual frequency range, virtual wideband, etc. To detect a channel outside the active uplink BWP, the frequency hopping transmission of the uplink signal is outside the active uplink BWP. Further, the terminal performs the frequency hopping transmission of the uplink signal in a first BWP, and a frequency range of the first BWP is outside a frequency range of the active uplink BWP. In another example, in a case where a bandwidth of the active uplink BWP exceeds a maximum bandwidth capability of the terminal, the active uplink BWP is taken as the first BWP, that is, the terminal performs the frequency hopping transmission of the uplink signal in the active uplink BWP. The uplink signal mentioned in various embodiments of the present application includes, but is not limited to, at least one of a sounding reference signal (SRS), a physical uplink control channel (PUCCH), a demodulation reference signal (DMRS), and a physical uplink shared channel (PUSCH). In subsequent embodiments, the uplink signal is taken as the SRS for example. The range outside the active uplink BWP mentioned in various embodiments of the present application can be at least one of a frequency domain position and numerology outside the range of the active uplink BWP. The uplink signal frequency hopping transmission method provided by the embodiments of the present application includes that a terminal receives frequency hopping configuration information, the frequency hopping configuration information including information indicating a first BWP; and the terminal performs frequency hopping transmission of an uplink signal in the first BWP, wherein a frequency range of the first BWP is outside a maximum bandwidth capability of the terminal, and the first BWP is configured with multiple hops. In the embodiments of the present application, under a large bandwidth, the terminal can perform frequency hopping transmission of the uplink signal in the first BWP based on the received frequency hopping configuration information, and effective transmission of the uplink signal can be realized, which is conducive to obtaining downlink CSI by using channel reciprocity through the uplink signal and improving the performance of the communication system. The uplink signal frequency hopping transmission method provided by the embodiments of the present application includes that a terminal can perform frequency hopping transmission of the uplink signal in a first BWP, and a frequency range of the first BWP can be outside a frequency range of an active uplink BWP. In a 6G single CC or BWP large bandwidth scenario, in a case where a downlink bandwidth capability does not match an uplink bandwidth capability, frequency hopping transmission (frequency hopping outside active UL BWP) of MIMO SRS outside an uplink BWP is supported in a single CC or BWP. The embodiments of the present application include two schemes: scheme 1, the terminal performs frequency hopping transmission of the uplink signal in the first BWP (which can include the active uplink BWP and the second BWP); and scheme 2, the terminal performs frequency hopping transmission of the uplink signal in the first BWP (which only includes the active uplink BWP). The two schemes will be described in detail below. Scheme 1 Scheme 1 configures the first BWP (also referred to as a virtual BWP), so that in the case where the bandwidth of the active uplink BWP does not exceed the maximum bandwidth capability of the terminal, and the frequency hopping transmission of the uplink signal exceeds the range of the active uplink BWP, the terminal performs frequency hopping transmission of the uplink signal in the first BWP, that is, the terminal can perform frequency hopping transmission of the uplink signal outside the active uplink BWP. In one embodiment, as shown in FIG. 3, the frequency range of the first BWP exceeds the frequency range of the active uplink BWP, and a plurality of hops are configured in the first BWP, such as SRS hop 0, SRS hop 1, SRS hop 2, and SRS hop 3 shown in FIG. 3. The number of hops configured in the first BWP is not limited to 4 hops in FIG. 3. In one embodiment, in the first BWP, the bandwidth of the terminal performing frequency hopping transmission of the uplink signal at the same time does not exceed the maximum bandwidth capability of the terminal, for example, in FIG. 3, the bandwidth of each hop does not exceed the maximum bandwidth capability of the terminal, so that each hop can be effectively transmitted. In one embodiment, the numerology of the first BWP is the same as that of the active uplink BWP, which is beneficial to reduce configuration overhead and reduce the complexity of the terminal. In one embodiment, the configuration of the first BWP is included in the component carrier (CC) configuration (such as servingcellconfig) or the configuration of the active uplink BWP, which is beneficial to save configuration overhead. Optionally, the CC configuration can also be referred to as the serving cell configuration (servingcellconfig). Optionally, the first BWP configuration is included in the active uplink BWP configuration, which can also be referred to as: associating the corresponding first BWP in the active BWP. In one embodiment, the terminal performs frequency hopping transmission of the uplink signal in the first BWP, and the frequency hopping transmission satisfies at least one of the following: 1) The bandwidth of the hop does not exceed the maximum bandwidth capability of the terminal, for example, in FIG. 3, the bandwidth of each hop does not exceed the maximum bandwidth capability of the terminal, so that each hop can be effectively transmitted. 2) The first hop does not exceed the range of the active uplink BWP of the terminal. 3) The bandwidths of multiple hops are equal. 4) There is an overlapping bandwidth between adjacent hops. 5) At least one adjacent hop in the multiple hop hops includes a switching time. This example can be that there is a switching time between adjacent hops, or there is a switching time between certain two adjacent hops. Optionally, the overlapping bandwidth in the above 4) is used to compensate for the channel error (such as phase error) between multiple hops, and better jointly estimates the channels of multiple hops. Optionally, the adjacent two hops in the above 4) can be adjacent in frequency domain position, or adjacent in time domain position. Optionally, the adjacent two hops in the above 4) can also have no overlapping bandwidth. Optionally, when the frequency domain starting position of the 'first hop or the frequency domain position of the lowest hop' is configured, the starting frequency domain position of other hops can be calculated according to the hop bandwidth. In one embodiment, there is a switching time between the adjacent two hops by default, as shown in the switching time in FIG. 3, which is beneficial for the terminal to perform hop switching. In one embodiment, the method further includes: the terminal determines whether a switching time is needed between the adjacent two hops based on the frequency domain position of the hop. Optionally, the method satisfies at least one of the following: 1) If the adjacent two hops are located within the active uplink BWP, no switching time is needed. This embodiment can determine whether a switching time is needed according to the frequency domain relationship between the adjacent two hops and the active uplink BWP. Optionally, if the adjacent two hops are located within the active uplink BWP, and the numerology of the adjacent two hops is the same as the numerology of the active uplink BWP, no switching time is needed. In other examples, if the adjacent two hops are located within the active uplink BWP, and the numerology of the adjacent two hops is different from the numerology of the active uplink BWP, a switching time is needed. 2) If the adjacent two hops are not within the active uplink BWP, a switching time is needed. The embodiment can determine whether switching time is needed according to the frequency domain relationship between the two adjacent hops and the activated uplink BWP. 3) If the frequency range of the two adjacent hops does not exceed the maximum uplink bandwidth capability of the terminal, no switching time is needed. The embodiment can determine whether switching time is needed according to the frequency range of the two adjacent hops. 4) If the frequency range of the two adjacent hops exceeds the maximum uplink bandwidth capability of the terminal, switching time is needed. The embodiment can determine whether switching time is needed according to the frequency range of the two adjacent hops. 5) If the two adjacent hops are located in the same sub-BWP, no switching time is needed between the two adjacent hops, wherein the first BWP is divided into a plurality of sub-BWPs, and the sub-BWP is shown in FIG. 4. The embodiment can divide the first BWP into a plurality of sub-BWPs, and determine whether switching time is needed between the two adjacent hops according to whether the two adjacent hops are located in the same sub-BWP. 6) If the two adjacent hops are not located in the same sub-BWP, switching time is needed between the two adjacent hops, wherein the first BWP is divided into a plurality of sub-BWPs. The embodiment can divide the first BWP into a plurality of sub-BWPs, and determine whether switching time is needed between the two adjacent hops according to whether the two adjacent hops are located in the same sub-BWP. Optionally, the'sub-BWP' can be replaced by other descriptions such as sub-band, sub-frequency range, sub-band, etc. The above-mentioned 'adjacent' can be time domain adjacent. In one embodiment, the method further comprises: the terminal determines whether switching time is needed between the two adjacent hops based on the indication of the network side device. In this embodiment, the network side device can directly indicate whether switching time is needed between two adjacent hops; or the network side device indicates whether switching time is needed when switching to a target hop, for example, by indicating whether switching to a target hop needs switching time through hop index or through bitmap. Optionally, the bitmap length is hop number, and bit 1 in the bitmap indicates that switching to the corresponding hop needs switching time. Optionally, the bitmap length is hop number-1 (for example, the first hop does not need switching time by default), and bit 1 in the bitmap indicates that switching to the corresponding hop needs switching time. The above scheme 1 can be further divided into scheme 1-1 and scheme 1-2, which will be described in detail below. Scheme 1-1 In the first BWP, multiple hops (also called first-level hops for easy distinction) are configured, and further, second-level hops are configured in each hop (if there are second-level hops, or if second-level hops are configured). The first-level hops are shown in FIG. 5, see SRS1 in FIG. 5 st stage hop 0, SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3. The second-level hops are defined in each first-level hop (which can be in a frequency range), as shown in FIG. 6, SRS1 st stage hop 0 can include four second-level hops, which are SRS2 st stage hop 0, SRS2 st stage hop 1, SRS2 st stage hop 2, SRS2 st stage hop 3; similarly, in SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3 can also include multiple second-level hops. Optionally, as shown in FIG. 6, the time domain duration of each first-level hop or second-level hop is the same. It can be understood that if no second-level hop is configured or no second-level hop exists, the first-level hop can also be referred to as a hop, that is, as described in the foregoing several embodiments, no distinction is made between the first-level hop and the second-level hop. Optionally, when the frequency domain starting position of the first hop or the hop with the lowest frequency domain position is configured, the starting frequency domain positions of other hops can be calculated according to the hop bandwidth. The hop mentioned in scheme 1-1 can include the first-level hop and the second-level hop; or can include only the first-level hop (or simply hop), that is, no second-level hop exists. The second-level hop can be referred to as a sub-hop. The terminal performs frequency hopping transmission of the uplink signal in the first BWP, and the method further includes that the terminal determines the time-frequency position of each hop of the frequency hopping transmission based on a first parameter, and the first parameter includes at least one of the following: the index of the hop, the number of hops, the bandwidth of each hop, the frequency domain starting position of each hop, the frequency domain starting position of the first hop or the hop with the lowest frequency domain position, the time domain position of each hop, the time domain position of the first hop, and the bandwidth of the overlapping of adjacent hops. Optionally, the network-side device can instruct the terminal to determine the time-frequency position of each hop of the frequency hopping transmission based on the first parameter. Optionally, the terminal determines the time-frequency position of each hop of the frequency hopping transmission based on the first parameter by default, as agreed in the protocol. In this example, if the network-side device additionally instructs the terminal to determine the time-frequency position of each hop of the frequency hopping transmission based on the first parameter, the terminal determines the time-frequency position of each hop of the frequency hopping transmission according to the manner instructed by the network-side device. Part or all of the above-mentioned first parameters can be determined according to network instructions or protocol agreements. The index of the hop (hop index) can also be referred to as the time index of the hop (hop time index) or the time counter of the hop (hop time counter), which is used to represent the count in the time domain of the hop. In one example, the first parameter includes the time domain position of each hop; wherein the terminal is configured with the time domain position of each hop, and the time domain position includes the time domain starting position and the time domain duration. In this example, the network-side device can configure the time domain position of each hop, including the time domain starting position of the hop and the time domain duration of the hop. Optionally, the time domain starting position of the hop includes at least one of the slot offset and the symbol offset; and the time domain duration of the hop includes at least one of the number of slots and the number of symbols. In one example, the first parameter comprises a time domain position of a first hop; wherein the terminal is configured with a starting time domain position of the first hop, a starting time offset of the hop, a duration of each hop. In this example, the network side device can configure a starting time domain position of a first hop, a starting time offset of a neighboring hop, a duration of each hop. The first parameter comprises a time domain position of a first hop; wherein the terminal is configured with a starting time domain position of the first hop, a time gap of a neighboring hop, a duration of each hop. In this example, the network side device can configure a starting time domain position of a first hop, a duration of each hop, a time gap of a neighboring hop. In one example, the terminal performing frequency hopping transmission of the uplink signal in the first BWP comprises: the terminal performing second level frequency hopping transmission of the uplink signal in each hop (such as a first level hop) in the first BWP, each hop containing a plurality of second level hops of the second level frequency hopping transmission, which can be applied to a scenario including first level hops and second level hops. Optionally, whether the terminal performs second level frequency hopping transmission in a hop can be indicated by the network. In one embodiment, the uplink signal comprises SRS, and the parameters of the second level frequency hopping transmission comprise at least one of the following: a number of the second level hops, C_SRS, B_SRS, b_hop, n_RRC, n_shift; wherein the C_SRS, the B_SRS, and the b_hop are related to a predefined frequency hopping table, used to determine the bandwidth, number or hierarchy of the second level hops; C_SRS is used to determine the row index of the frequency hopping table, B_SRS is used to determine the column index of the frequency hopping table, and b_hop is used to determine the total bandwidth of the second level frequency hopping; n_RRC represents an offset parameter related to calculating the frequency domain position of the second level hop; and n_shift represents a common frequency domain offset of a plurality of second level hops relative to a frequency domain reference point.

In this embodiment, the network side device can directly indicate whether a switching time is needed between two adjacent hops; or the network side device indicates whether a switching time is needed when switching to a target hop, for example, by indicating whether a switching time is needed when switching to a target hop through hop index or through a bitmap. Optionally, the bitmap has a length of the number of hops, and bit 1 in the bitmap indicates that a switching time is needed when switching to the corresponding hop. Optionally, the bitmap has a length of hop number - 1 (e.g. the first hop does not need a switching time by default), and bit 1 in the bitmap indicates that a switching time is needed when switching to the corresponding hop. Scheme 2-2 The uplink signal (e.g. SRS) frequency hopping is defined in a sub-BWP, and the inter-sub-BWP frequency hopping transmission needs a switching time. In one example, the terminal performs the frequency hopping transmission of the uplink signal in the activated UL BWP, comprising: the activated uplink BWP contains multiple sub-BWPs, and each sub-BWP contains at least one hop (i.e. the frequency hopping configuration is in the sub-BWP).

Optionally, the frequency domain reference point of the common frequency domain offset of multiple second-level hops in a sub-BWP is the starting position in the sub-BWP, or the starting position of the active BWP, or the reference point A (point A) of the CC. Optionally, the frequency domain reference points of the common frequency domain offsets corresponding to the hops in different sub-BWPs can be the starting positions in the respective sub-BWPs, or the starting position of the first BWP, or the reference point A (point A) of the CC. Optionally, the frequency hopping table is as shown in Table 1, and the frequency hopping table is related to at least one of C_SRS, B_SRS, m SRS,0 m SRS,1 m SRS,2 m SRS,3 , N0, N1, N2, and N3. Among them, C_SRS is used to determine the row index of the frequency hopping table; B_SRS is used to determine the column index of the frequency hopping table, and is also used to determine the minimum hop bandwidth in the sub-BWP; m SRS,0 m SRS,1 m SRS,2 m SRS,3 is used to determine the hop bandwidth in the sub-BWP; N0, N1, N2, and N3 are used to determine the number of hops in the sub-BWP; and b_hop is used to determine the total bandwidth of the frequency hopping in the sub-BWP, that is, the bandwidth in the column corresponding to B_SRS = b_hop in Table 1. Optionally, b_hop = 0. In an embodiment, the method further comprises: after the frequency hopping transmission of the uplink signal is completed, the terminal switches to the default sub-BWP; or if two adjacent hops are located in different sub-BWPs and the time interval exceeds the switching time, the terminal switches to the default sub-BWP, or stays in the previous sub-BWP, or switches to the next sub-BWP in advance. In an embodiment, the terminal performs frequency hopping transmission of the uplink signal in the sub-BWP of the activated uplink BWP includes that the terminal switches from one of the sub-BWPs to another of the sub-BWPs to perform frequency hopping transmission of the uplink signal after the frequency hopping transmission of the uplink signal in the one of the sub-BWPs is completed. In this embodiment, the terminal needs to complete frequency hopping transmission in a sub-BWP and then switch to a new sub-BWP to perform frequency hopping transmission of the uplink signal to minimize the number of switching. For example, the uplink signal is SRS, and one round of frequency hopping in a sub-BWP needs X times, the index of the sub-BWP is determined based on the formula floor(n_SRS / X), and the frequency hopping index in the sub-BWP is determined based on the formula mod(n_SRS,X), where n_SRS is the SRS frequency hopping count. In an embodiment, the terminal performs frequency hopping transmission of the uplink signal based on the order of the plurality of sub-BWPs; or the terminal interleaves frequency hopping transmission of the uplink signal in the plurality of sub-BWPs. The following will introduce the scheduling restrictions or collision rules introduced by frequency hopping transmission of the uplink signal. In an embodiment, the time domain position of the switching time is related to the time domain position of the hop. Alternatively, the switching time is located in the N symbols adjacent to the first symbol of the hop; or the switching time is located in the N symbols adjacent to the last symbol of the hop. In an embodiment, the method further includes that the terminal performs transmission of a first channel or signal based on a first rule, and the first rule includes at least one of the following: 1) The interval between the last symbol of the first channel or signal and the first symbol of the frequency hopping transmission of the uplink signal contains at least N symbols and an additional time interval T. 2) The interval between the last symbol of the first channel or signal and the first symbol of the frequency hopping transmission of the uplink signal contains at least N symbols. N is the preparation time of the first channel or signal, and N is calculated based on the smallest SCS among the following: the hop of the uplink signal, the SCS of the first channel or signal, and the SCS of the PDCCH; T is the switching time of the BWP of the frequency hopping transmission of the uplink signal and the transmission of the first channel or signal, and N and T are positive integers. Specifically, taking frequency hopping of SRS as an example. For a symbol Start SRS hop, symbol N SOther channels or signals (e.g. PUSCH, PUCCH) starting at the same time as the SRS hop, the UE considers the following when applying the dropping rule: The gap between the last symbol of the DCI associated PDCCH and the SRS symbol contains at least N2 symbols and an additional time gap where is the switching time between the SRS hop and the BWP (e.g. active BWP) of the other channel or signal transmission. The gap between the last symbol of the DCI associated PDCCH and the colliding other channel or signal N S contains at least N2 symbols. where N2 is the PUSCH preparation time, N2 is calculated based on the smallest SCS among the SRS hop, the SCS of the other channel / signal, the SCS of the PDCCH. In one embodiment, the method further comprises: in case the frequency hopping transmission of the uplink signal and the transmission of the second channel or signal overlap in the same symbol, the terminal determines to perform the frequency hopping transmission of the uplink signal or the transmission of the second channel or signal based on the priority of the frequency hopping transmission of the uplink signal and the second channel or signal. For example, if the priority of the frequency hopping transmission of the uplink signal is higher than the priority of the second channel or signal, the frequency hopping transmission of the uplink signal is performed and the second channel or signal is dropped; for another example, if the priority of the frequency hopping transmission of the uplink signal is lower than the priority of the second channel or signal, the transmission of the second channel or signal is performed and the frequency hopping transmission of the uplink signal is dropped. To make the uplink signal frequency hopping transmission method provided by the embodiments of the present application more clear, the following will be described in combination with several specific embodiments. Embodiment one Embodiment one mainly introduces the above scheme 1-1. The implementation of scheme 1-1 is shown in FIG. 5, the first hop is a small dot filled block, see SRS1 st stage hop 0, SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3. Of course, the first hop here can also be expressed as 'hop'. The switching between two adjacent 1st stage hops requires switching time. If the 1st 1st stage hop is in the active uplink BWP frequency range, no switching time is required for the active uplink BWP to switch to the 1st 1st stage hop. The 2nd stage hops are defined within each 1st stage hop, and no switching time is required between adjacent 2nd stage hops. As shown in FIG. 6, SRS1 st contains 4 2nd stage hops, SRS2 st , SRS2 st , SRS2 st , SRS2 st , SRS2 st , SRS1 st , SRS1 st , SRS1 Further, the frequency domain starting position of the 1st stage hop is offset by n_shift The offset of the frequency domain starting position of the 2nd stage hop within the 1st stage hop is n_shift wherein, n_shift is the offset relative to the common frequency domain reference point of the multiple 1st stage hops (the frequency domain reference point is the starting point of the first BWP or the reference point A of the CC); n_shift is the offset relative to the frequency domain starting position of the corresponding 1st stage hop. 1) The following will introduce how to determine the frequency domain starting position offset of the 1st stage hop wherein, the frequency domain starting position of the 1st stage hop is can be determined according to the following formula (sequential frequency hopping pattern): wherein, n_shift is the hop offset of the 1st hop, N is the hop index (or hop counter) of each 1st stage hop, hop1 m is the number of 1st stage hops, SRS,hop1 is the bandwidth of the 1st stage hop, is the SCS number of one RB. Or, considering the'staggered pattern' of the 1st level hop, it can be determined according to the following formula: Further, Optionally, It can be determined according to the time domain order of the 1st level hop, or according to the SRS frequency hopping count n SRS Determination. Wherein n SRS is the frequency hopping count containing the 2nd level hop, if there is no 2nd level hop or no 2nd level hop is configured, Optionally, if the 2nd level hop is configured, Where N hop1 is the number of 2nd level hops contained in the 1st level hop. Optionally, if there are X rounds of 2nd level hops in the 1st level hop, 2) The following will introduce how to determine the frequency domain starting position offset of the 2nd level hop Wherein, B SRS is the 2nd level frequency hopping parameter used to determine the bandwidth of the 2nd level hop, b is the order of the 2nd level frequency hopping, m SRS,b is the bandwidth corresponding to the bth order of the 2nd level frequency hopping, n b is the frequency domain position index. Optionally, the bandwidth m SRS,0 corresponding to the 0th order of the 2nd level frequency hopping is equal to the bandwidth of the 1st level hop, or less than the bandwidth of the 1st level hop. Optionally, b hop <B SRS ; optionally, when b hop <B SRS , enable the 2nd level frequency hopping. Further, Wherein, b hop is the 2nd level frequency hopping parameter used to determine the total bandwidth of the 2nd level hop, is the hop index (or hop counter) of the 2nd level hop in the 1st level hop. Optionally, It can be determined according to the time domain order of the 2nd level hop, or according to the SRS frequency hopping count n SRSDetermination. Optionally, if the 2nd level hop is configured, then where N hop2 is the number of 2nd level hops contained in the 1st level hop. Optionally, if there are X rounds of 2nd level hops in the 1st level hop, then Further, where N b is the number of narrow bands corresponding to the bth order of the 2nd level hop. The frequency domain starting position offset of each 2nd level hop (relative to the reference point A of the first BWP starting point or CC) can be determined according to the following formula: Optionally, the 1st and 2nd level hop parameters in the above formula can be determined by referring to the parameters described in the previous embodiment 1-1 and the frequency hopping table, etc. Embodiment two 1) For embodiment two, the frequency domain starting position offset of the hop can be determined according to the following formula: wherein, is the offset of n_shift PRBs relative to the common frequency domain reference point of multiple hops. The frequency domain reference point is the reference point A of the first BWP starting point or CC. B SRS is the frequency hopping parameter used to determine the bandwidth of the hop, b is the order of frequency hopping, m SRS,b is the bandwidth corresponding to the bth order of frequency hopping, n b is the frequency domain position index. Further, wherein, b hop is the frequency hopping parameter used to determine the total bandwidth of the hop, n SRS is the hop counter. Further, wherein, N b is the number of narrow bands corresponding to the bth order of the 2nd level hop. Optionally, the parameters in the above formula can be determined by referring to the parameters in the previous embodiment 1-2 and the frequency hopping table, etc. Further, after the above hop is determined, if the 2nd level hop within each hop is configured. The determination method of the 2nd level frequency hopping can also be referred to in embodiment one. Optionally, the bandwidth corresponding to the 0th order of the 2nd level frequency hopping is equal to or less than the bandwidth of the first level hop. Further, the implementation of whether the adjacent hop needs switching time in scheme 1-2 is as follows: 1) The adjacent hop needs switching time by default, as shown in FIG. 3. 2) Whether the adjacent hop needs switching time can be determined according to the frequency domain position of the adjacent hop. In an example, according to the relationship between the hop and the activated uplink BWP, if the adjacent hop is located in the activated uplink BWP, no switching time is needed; otherwise, switching time is needed. As shown in FIG. 7, the SRS hop 1 and hop 2 are located in the activated uplink BWP and the numerology is consistent with the activated uplink BWP, so no switching time is needed. In an example, according to the frequency range relationship of the adjacent hop, if the frequency range of the adjacent hop does not exceed the maximum bandwidth capability of the terminal, no switching time is needed; otherwise, switching time is needed. As shown in FIG. 8, the frequency range of the SRS hop 0, SRS hop 1 and SRS hop 2 does not exceed the maximum bandwidth capability of the terminal, so no switching time is needed; while the switching time is needed between the SRS hop 3 and SRS hop 2. Optionally, the switching time of the adjacent hop in the scheme of the application can be determined according to the UE capability. In an example, the virtual BWP can be divided into blocks (such as sub-BWP), if the adjacent hop is located in the same sub-BWP, no switching time is needed; otherwise, switching time is needed. As shown in FIG. 9, the frequency range of the SRS hop 0, SRS hop 1 and SRS hop 2 is located in the sub-BWP 0, so no switching time is needed; while the switching time is needed between the SRS hop 3 and SRS hop 2 which are located in different sub-BWPs. 3) Whether the adjacent hop needs switching time can be determined according to the network indication. As shown in FIG. 10, the network indicates a bitmap. The length of the bitmap is the same as the number of hops, and each bit value of the bitmap indicates whether there is switching time before the corresponding hop. For example, the bitmap in FIG. 10 is

[0001] , which indicates that there is switching time between the SRS hop 3 and SRS hop 2. Optionally, the length of the bitmap is the number of hops, and the bit is 1 in the bitmap, which indicates that switching to the corresponding hop needs switching time. Optionally, the length of the bitmap is hop-1 (such as the first hop does not need switching time by default), and the bit is 1 in the bitmap, which indicates that switching to the corresponding hop needs switching time. Embodiment Three This embodiment can be combined with any of the above embodiments. If multiple hops occur in one slot, time gap is configured between adjacent hops, as shown in Figure 11, which is not less than the switching time between hops. The time gap between hops will affect the current SRS resource continuous symbol design, and the corresponding SRS resource pattern is shown in Figure 12. The left side of Figure 12 is the existing SRS resource pattern, and the right side of Figure 12 is the SRS resource pattern design considering the time gap. This embodiment can also introduce SRS symbol groups, indicating the number of consecutive symbols. Adjacent symbol groups have a time gap, and the time gap unit is symbol. Further, the symbol position of SRS resource in a slot (or the symbol position of symbol group in a slot) can be determined according to at least one of the following parameters: starting symbol, symbol number, gap duration, and symbol number of symbol group. Any of the above parameters can be determined by at least one of the following ways: protocol agreement, network configuration, and UE selection. ‘Starting symbol’ indicates the starting symbol position of SRS resource in a slot. ‘Symbol number’ indicates the number of symbols of SRS resource in a slot. ‘Gap duration’ indicates the number of gap symbols of adjacent symbol groups. Optionally, the gap duration of adjacent symbol groups is the same. Optionally, the gap duration of adjacent symbol groups can be different, and here the gap duration can include multiple (or a group). One implementation: when calculating the symbol position of SRS resource in a slot, the symbol occupied by the potential gap duration is skipped. Optionally, gap duration can also be expressed by'symbol group interval'. That is, symbol group interval is the interval between the start symbols of adjacent symbol groups. Gap duration can be obtained by'symbol group interval' minus'symbol number of symbol group'. 'symbol number of symbol group' (or duration of symbol group) indicates the number of consecutive symbols in one symbol group. Optionally, symbol number of symbol group can be obtained by'repetition factor'. For example, repetition factor is equal to symbol number of symbol group. Optionally, symbol number of different symbol groups in one slot is the same (regular case). Optionally, symbol number of different symbol groups in one slot can be different (special case), then symbol number of symbol group can contain multiple (or a group). One embodiment: the symbol number of a group of symbol groups contains two values, the first value is the symbol number of the first symbol group, and the second value is the symbol number of the other symbol groups, and the first value is greater than the second value (or the first value is an integer multiple of the second value, and the integer > 1). Optionally, symbol number of symbol group can be obtained by'symbol group number'. Optionally, symbol number of symbol group is equal to the number of symbols of SRS resource in slot / symbol group number. Optionally, the symbol sequence number in symbol group is 0, 1, … symbol number in symbol group-1. Further, the mapping relationship between the symbol sequence number of the symbol in the SRS resource in the SRS resource and the symbol sequence number in the slot is obtained according to at least one of the above parameters. Further, it can be determined according to the following parameters: l0, l', l'', wherein, lo is the starting symbol position of the SRS resource in one slot, l' is the symbol index within the SRS resource, and is the number of symbols of the SRS resource in one slot. The symbol l' within the SRS resource corresponds to the symbol position l in the slot (the symbol position in the slot can be applied to actual SRS resource mapping, such as determining the relative RE offset corresponding to the symbol l'): wherein, is the number of symbols of the symbol group, is the Gap duration. Optionally, wherein, R is the repetition factor.
