Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to an uplink signal frequency hopping transmission method, a terminal and a network side device. BACKGROUND

[0002] Large bandwidth is a key driving factor for super high data rate transmission. For downlink transmission, one component carrier (CC) or one bandwidth part (BWP) may support a super large bandwidth such as 800M in the future; but for uplink transmission, due to different terminal transceiving capabilities and different service requirements, it is impossible to support larger bandwidth transmission like downlink transmission, such as only supporting 200M or 100M.

[0003] In a time division duplex (TDD) system, in order to realize channel reciprocity, some uplink signals (such as sounding reference signals SRS) are used for uplink channel measurement, and the channel state information (CSI) of the downlink is calculated by using channel reciprocity.

[0004] In a large bandwidth scenario, due to different terminal transceiving capabilities and different service requirements, the terminal cannot determine how to send uplink signals, and thus cannot obtain the downlink CSI by using channel reciprocity through the uplink signals, resulting in that channel estimation cannot be performed in a large bandwidth scenario, and communication performance is affected.

[0045] 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.

[0046] As shown in the figure, 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 includes the following steps. Figure 2

[0047] S202: The terminal receives frequency hopping configuration information, and the frequency hopping configuration information includes information indicating a first BWP.

[0048] In this embodiment, the frequency hopping configuration information can include the frequency range of the first BWP and the like, and a plurality of hops are configured in the first BWP. The frequency hopping configuration information can also include at least one of the following information: the index of each 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 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.

[0049] 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 a plurality of hops are configured in the first BWP.

[0050] As shown in the figure, the terminal performs frequency hopping transmission of the uplink signal in the first BWP, the frequency range of the first BWP exceeds the maximum bandwidth capability of the terminal, a plurality of hops are configured in the first BWP, as shown in SRS hop 0, SRS hop1, SRS hop 2 and SRS hop 3 in Figure 3 Figure 3 The number of hops configured in the first BWP is not limited to 4 hops in Figure 3

[0051] ​​​In one example, in a case that a bandwidth of the activated uplink BWP does not exceed a maximum bandwidth capability of the terminal, and the frequency hopping transmission of the uplink signal is out of a range of the activated uplink BWP, the frequency range of the first BWP is out of the frequency range of the activated uplink BWP. Optionally, the first BWP includes the activated uplink BWP and a second BWP, which can be referred to as a "virtual BWP", and the "virtual BWP" is only used for reference of frequency domain location 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.

[0052] In order to detect a channel out of the activated uplink BWP, the frequency hopping transmission of the uplink signal is out of the activated uplink BWP. Further, the terminal performs the frequency hopping transmission of the uplink signal in the first BWP, and the frequency range of the first BWP is out of the frequency range of the activated uplink BWP.

[0053] In another example, in a case that a bandwidth of the activated uplink BWP exceeds a maximum bandwidth capability of the terminal, the activated uplink BWP is taken as the first BWP, that is, the terminal performs the frequency hopping transmission of the uplink signal in the activated uplink BWP.

[0054] 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 description.

[0055] The "out of the range of the activated uplink BWP" mentioned in various embodiments of the present application can be at least one of a frequency domain location and numerology out of the range of the activated uplink BWP.

[0056] The uplink signal frequency hopping transmission method provided in this application embodiment involves a terminal receiving frequency hopping configuration information, which includes information indicating a first frequency hopping window (BWP). The terminal performs uplink signal frequency hopping transmission within the first BWP, wherein the frequency range of the first BWP exceeds the maximum bandwidth capability of the terminal, and multiple hops are configured within the first BWP. In this application embodiment, under high bandwidth conditions, the terminal can perform uplink signal frequency hopping transmission within the first BWP based on the received frequency hopping configuration information, achieving effective uplink signal transmission. This facilitates obtaining downlink CSI through channel reciprocity of the uplink signal, thereby improving communication system performance.

[0057] The uplink signal frequency hopping transmission method provided in this application embodiment allows the terminal to perform uplink signal frequency hopping transmission within a first BWP. The frequency range of the first BWP can exceed the frequency range of the active uplink BWP. In 6G single CC or BWP large bandwidth scenarios, when the downlink bandwidth capability and uplink bandwidth capability are mismatched, it supports frequency hopping outsideactive UL BWP within a single CC or BWP with MIMO SRS configured.

[0058] This application includes two schemes: Scheme 1, the terminal performs frequency hopping transmission of the uplink signal within the first BWP (which may include the active uplink BWP and the second BWP); Scheme 2, the terminal performs frequency hopping transmission of the uplink signal within the first BWP (which only includes the active uplink BWP). The two schemes will be described in detail below.

[0059] Option 1

[0060] Option 1 involves configuring a first BWP (or virtual BWP). When 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 terminal performs frequency hopping transmission of the uplink signal within the first BWP. In other words, the terminal can perform frequency hopping transmission of the uplink signal outside the activated uplink BWP.

[0061] In one embodiment, such as Figure 3 As shown, the frequency range of the first BWP exceeds the frequency range of the activated uplink BWP, and the first BWP is configured with multiple hops, such as... Figure 3 As shown in SRS hop 0, SRS hop 1, SRS hop 2, and SRS hop 3, the number of hops configured within the first BWP is not limited to [the number of hops configured within the first BWP]. Figure 3 The limit is 4 hops.

[0062] In one embodiment, within the first BWP, the bandwidth of the terminal for frequency hopping transmission of the uplink signal at the same time does not exceed the maximum bandwidth capability of the terminal, for example, in Figure 3 each hop bandwidth does not exceed the maximum bandwidth capability of the terminal, so that each hop can be effectively transmitted.

[0063] In one embodiment, the numerology of the first BWP is the same as that of the activated uplink BWP, which is beneficial to reduce configuration overhead and reduce the complexity of the terminal.

[0064] In one embodiment, the configuration of the first BWP is included in the component carrier (CC) configuration (such as servingcellconfig) or the activated uplink BWP configuration, which is beneficial to save configuration overhead.

[0065] Optionally, the CC configuration can also be expressed as the serving cell configuration (servingcellconfig).

[0066] Optionally, the first BWP configuration in the activated uplink BWP configuration can also be expressed as: associating the corresponding first BWP in the activated BWP.

[0067] 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:

[0068] 1) The bandwidth of the hop does not exceed the maximum bandwidth capability of the terminal, for example, in Figure 3 each hop bandwidth does not exceed the maximum bandwidth capability of the terminal, so that each hop can be effectively transmitted.

[0069] 2) The first hop does not exceed the range of the activated uplink BWP of the terminal.

[0070] 3) The bandwidths of multiple hops are equal.

[0071] 4) There is an overlapping bandwidth between adjacent hops.

[0072] 5) The multiple hops at least include adjacent hops with switching time. This example can be that there is switching time between adjacent hops, or there is switching time between certain two adjacent hops.

[0073] 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 joint estimation of the channels of multiple hops.

[0074] Optionally, the two adjacent hops in 4) above can be adjacent in frequency domain, or adjacent in time domain.

[0075] Optionally, the two adjacent hops above can also have no overlapping bandwidth.

[0076] 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.

[0077] In one embodiment, there is a switching time between the two adjacent hops by default, see the switching time in Figure 4 , which is conducive to hop switching of the terminal.

[0078] In one embodiment, the method further comprises: the terminal determining whether a switching time is needed between the two adjacent hops based on the frequency domain positions of the hops.

[0079] Optionally, the method meets at least one of the following:

[0080] 1) If the two adjacent hops are located within the active uplink BWP, no switching time is needed.

[0081] This embodiment can determine whether a switching time is needed according to the frequency domain relationship between the two adjacent hops and the active uplink BWP.

[0082] Optionally, if the two adjacent hops are located within the active uplink BWP, and the numerology of the two adjacent hops is the same as the numerology of the active uplink BWP, no switching time is needed. In other examples, if the two adjacent hops are located within the active uplink BWP, and the numerology of the two adjacent hops is different from the numerology of the active uplink BWP, a switching time is needed.

[0083] 2) If the two adjacent hops are not located within the active uplink BWP, a switching time is needed.

[0084] This embodiment can determine whether a switching time is needed according to the frequency domain relationship between the two adjacent hops and the active uplink BWP.

[0085] 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.

[0086] This embodiment can determine whether a switching time is needed according to the frequency range of the two adjacent hops.

[0087] 4) If the frequency range of two adjacent hops exceeds the maximum uplink bandwidth capability of the terminal, switching time is needed.

[0088] In this embodiment, whether switching time is needed between two adjacent hops can be determined according to the frequency range of the two adjacent hops.

[0089] 5) If 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, as shown in the following figure. Figure 5

[0090] In this embodiment, the first BWP is divided into a plurality of sub-BWPs, and whether switching time is needed between two adjacent hops can be determined according to whether the two adjacent hops are located in the same sub-BWP.

[0091] 6) If 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.

[0092] In this embodiment, the first BWP is divided into a plurality of sub-BWPs, and whether switching time is needed between two adjacent hops can be determined according to whether the two adjacent hops are located in the same sub-BWP.

[0093] Optionally, the'sub-BWP' can also be replaced by other descriptions, such as sub-band, sub-frequency range, sub-band, etc.

[0094] In the above, 'adjacent' can be time-domain adjacent.

[0095] In one embodiment, the method further comprises: the terminal determines whether switching time is needed between two adjacent hops based on the indication of the network-side device.

[0096] 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 time is needed when switching to a target hop through a hop index or a bitmap. Optionally, the bitmap length is the number of hops, and bit 1 in the bitmap indicates that switching time is needed when switching to the corresponding hop. Optionally, the bitmap length is hop number-1 (for example, the first hop does not need switching time), and bit 1 in the bitmap indicates that switching time is needed when switching to the corresponding hop.

[0097] ​The above-described scheme 1 can be further divided into scheme 1-1 and scheme 1-2, which will be described in detail below.

[0098] Scheme 1-1

[0099] Within the first BWP, a plurality of hops (also referred to as first-level hops for ease of distinction) are configured, and further, within each hop, a second-level hop is configured (if there is a second-level hop, or if a second-level hop is configured).

[0100] The first-level hop is as shown in FIG. 1, and the SRS1 Figure 5 in FIG. 1 Figure 6 st stage hop 0, SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3.

[0101] The second-level hop is defined within each first-level hop (which can be within a frequency range), as shown in FIG. 2, and the SRS1 Figure 6 in FIG. 2 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, SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3 can also include a plurality of second-level hops.

[0102] Optionally, as shown in FIG. 3, the time domain duration of each first-level hop or second-level hop is the same. Figure 4

[0103] It can be understood that if there is no second-level hop configured or no second-level hop, the 'first-level hop' can also be referred to as 'hop', that is, as described in the foregoing embodiments, there is no need to distinguish between the first-level hop and the second-level hop.

[0104] ​​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 only include the "first level hop (or simply hop)", that is, there is no "second level hop". The second level hop can be referred to as a sub-hop.

[0105] The terminal performs frequency hopping transmission of the uplink signal in the first BWP, and the method further includes: 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.

[0106] 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.

[0107] 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 by 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 instructions of the network side device.

[0108] Part or all of the above-mentioned first parameters can be determined according to network instructions or protocol agreements.

[0109] 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.

[0110] 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.

[0111] In this example, the network side device can configure the time domain position of each hop, including the hop time domain starting position and the hop time domain duration. Optionally, the hop time domain starting position includes at least one of the slot offset and the symbol offset; and the hop duration includes at least one of the slot number and the symbol number.

For example: the number of the second level hops in each hop is the same, the bandwidth of the second level hop is the same, etc.; but the frequency domain position (such as n_shift) of the second level hop in each hop can be different, etc.

[0134] The above scheme 1-1 introduces 2-level frequency hopping transmission: the first level hop is frequency hopping outside the active uplink BWP, there is a switching time between adjacent hops, realizing carrier (or radio frequency) switching, traversing a larger bandwidth beyond the active UL BWP; the second level is frequency hopping within the first level hop (adjacent hops have no switching time), realizing bandwidth traversal within the UE bandwidth capability, and increasing the audibility of the reference signal.

[0135] Scheme 1-2

[0136] The uplink signal (such as SRS) frequency hopping is defined in the first BWP, not in the inactive uplink BWP.

[0137] Optionally, the frequency domain position reference point (such as the parameter n_shift) of the hop is the start position of the first BWP.

[0138] In one embodiment, the terminal performs frequency hopping transmission of the uplink signal in the first BWP, the uplink signal including SRS, and the method further includes that the terminal determines each of the hop time-frequency positions of the frequency hopping transmission based on a second parameter, the second parameter including at least one of C_SRS, B_SRS, b_hop, n_RRC, and n_shift; wherein the C_SRS, the B_SRS, and the b_hop are related to a predefined frequency hopping table, and are used to determine the bandwidth, the number, or the hierarchy of the hop; the C_SRS is used to determine the row index of the frequency hopping table, the B_SRS is used to determine the column index of the frequency hopping table, and the b_hop is used to determine the total bandwidth of the frequency hopping; the n_RRC represents an offset parameter related to calculating the frequency domain position of the hop; and the n_shift represents a common frequency domain offset of the plurality of hops relative to a frequency domain reference point. Optionally, the frequency domain reference point of the plurality of hops is the starting position of the first BWP, or the reference point A of the CC.

Optionally, b_hop = 0.

[0140] Optionally, the network side device can instruct the terminal to determine each of the hop time-frequency positions of the frequency hopping transmission based on the second parameter.

[0141] Optionally, the terminal determines each of the hop time-frequency positions of the frequency hopping transmission based on the second parameter by default, as agreed in the protocol. In this example, if the network side device additionally instructs the terminal to determine each of the hop time-frequency positions of the frequency hopping transmission based on the second parameter, the terminal determines each of the hop time-frequency positions of the frequency hopping transmission according to the manner instructed by the network side device.

[0142] In the above-mentioned scheme 1, the method further comprises: in the case that the time domain length between two adjacent hops is greater than the switching time, the terminal needs to switch to the active uplink BWP or the active downlink BWP first when switching between 2 hops.

[0143] In the above-mentioned scheme 1, the total bandwidth of the frequency hopping transmission does not exceed the frequency range of the active downlink BWP of the terminal. Optionally, for the TDD scenario, the active uplink BWP and the associated active downlink BWP have the same BWP index.

[0144] In the above-mentioned scheme 1, when power control is performed on the frequency hopping transmission of the uplink signal, the power control associated BWP can refer to the first BWP.

[0145] Optionally, in the above-mentioned frequency hopping transmission, the frequency domain position of the starting hop does not exceed the frequency range of the active uplink BWP, that is, the bandwidth is within the frequency range of the active uplink BWP, and the numerology is the same as that of the active uplink BWP.

[0146] Scheme 2

[0147] In the case that the bandwidth of the active uplink BWP exceeds the maximum bandwidth capability of the terminal (for example, the bandwidth of the active uplink BWP is approximately equal to the bandwidth of the active downlink BWP), the terminal performs the frequency hopping transmission of the uplink signal in the first BWP (that is, the active uplink BWP); wherein the active uplink BWP is configured with multiple hops.

[0148] In one embodiment, in the active uplink BWP, the bandwidth of the terminal performing the frequency hopping transmission of the uplink signal at the same time does not exceed the maximum bandwidth capability of the terminal.

[0149] Further, the first BWP (active uplink BWP) is divided into multiple sub-BWPs (or sub-channels, or BWP-blocks), and the actual transmission of the terminal is within the sub-BWP; the numerology of different sub-BWPs is the same and meets the bandwidth capability of the terminal.

[0151] 1) The frequency hopping transmission is located within the sub-BWP.

[0152] 2) The numerology of at least two sub-BWPs is the same.

[0153] 3) There is a switching time between two of the sub-BWPs (i.e. different hops are located in different sub-BWP frequency ranges, and switching between different hops is equivalent to switching between sub-BWPs, which requires switching time).

[0154] 4) The configuration of the sub-BWPs includes at least one of the following: the identification of the sub-BWP (sub-BWP ID), the bandwidth of the sub-BWP, and the starting frequency domain position of each sub-BWP.

[0155] 5) There is a default sub-BWP (or reference sub-BWP) among the multiple sub-BWPs. After completing the frequency hopping transmission of the uplink signal, the terminal automatically returns to the default sub-BWP; or, if the interval between two adjacent hops is greater than the switching time (if switching time is required), the terminal switches back to the default sub-BWP.

[0156] 6) The default sub-BWP among the multiple sub-BWPs is used for transmitting PUSCH or PUCCH.

[0157] In one embodiment, the terminal performs frequency hopping transmission of the uplink signal in the first BWP includes: the terminal performs frequency hopping transmission of the uplink signal in the sub-BWPs of the first BWP (active uplink BWP); wherein at least one hop is configured in each sub-BWP. Each sub-BWP can be configured with one hop; or each sub-BWP can be configured with multiple hops.

[0158] The above-mentioned scheme 2 can be further divided into scheme 2-1 and scheme 2-2, which will be described in detail below.

[0159] Scheme 2-1

[0160] The frequency hopping of the uplink signal (such as SRS) is defined in the active uplink BWP. That is, the terminal determines the time-frequency position of each hop of the frequency hopping transmission based on a third parameter, which includes at least one of the following: 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, which is used to determine the bandwidth, number or hierarchy of the hop; 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 frequency hopping; n_RRC represents an offset parameter related to calculating the frequency domain position of the hop; n_shift represents the common frequency domain offset of multiple hops relative to the frequency domain reference point. Optionally, the frequency domain reference point of multiple hops is the starting position of the active uplink BWP, or the reference point A (Point A) of the CC.

[0161] Optionally, the predefined frequency hopping table is shown in Table 1, where the frequency hopping table is determined by C_SRS, B_SRS, m SRS,0 m SRS,1 m SRS, 2m SRS,3 , N0, N1, N2, N3, where 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; m SRS,0 m SRS,1 m SRS,2 m SRS,3 is used to determine the hop bandwidth; N0, N1, N2, N3 are used to determine the hop number; and b_hop is used to determine the total bandwidth of the frequency hopping, i.e., the bandwidth in the column corresponding to B_SRS = b_hop in Table 1. Optionally, b_hop = 0.

[0162] In one embodiment, there is a switching time between two adjacent hops, as shown in the switching time. Figure 5

[0163] In one embodiment, the method further comprises: determining, by the terminal, whether a switching time is needed between two adjacent hops based on the frequency domain position of the hops.

[0164] Optionally, the method satisfies at least one of the following:

[0165] 1) If two adjacent hops are located in the same sub-BWP, no switching time is needed.

[0166] 2) If two adjacent hops are not located in the same sub-BWP, a switching time is needed.

[0167] 3) If the frequency range of two adjacent hops does not exceed the maximum uplink bandwidth capability of the terminal, no switching time is needed.

[0168] 4) If the frequency range of two adjacent hops exceeds the maximum uplink bandwidth capability of the terminal, a switching time is needed.

[0169] In one embodiment, the method further comprises: determining, by the terminal, whether a switching time is needed between two adjacent hops based on the indication of the network side device.

[0170] ​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.

[0171] Scheme 2-2

[0172] The uplink signal (for example, SRS) frequency hopping is defined in a sub-BWP, and the inter-sub-BWP frequency hopping transmission needs switching time.

[0173] In one example, the terminal performs frequency hopping transmission of the uplink signal in the activated UL BWP, including that the activated uplink BWP contains multiple sub-BWPs, and each sub-BWP contains at least one hop (that is, frequency hopping is configured in the sub-BWP).

[0174] In one embodiment, the uplink signal includes SRS, and the parameters of the frequency hopping transmission in the sub-BWP include at least one of the following: the number of hops contained in the sub-BWP, C_SRS, B_SRS, b_hop, n_RRC, and n_shift; wherein the C_SRS, the B_SRS, and the b_hop are related to a predefined frequency hopping table, and are used to determine the bandwidth, number, or hierarchy of the hop; 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 frequency hopping in the sub-BWP; n_RRC represents an offset parameter related to calculating the frequency domain position of the hop; and n_shift represents the common frequency domain offset of multiple hops relative to a frequency domain reference point. Optionally, the frequency domain reference point of the common frequency domain offset of multiple second-level hops in one sub-BWP is the starting position in the sub-BWP, or the starting position of the activated 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.

[0175] Optionally, the frequency hopping table is shown in Table 1, and the frequency hopping table is related to C_SRS, B_SRS, and m SRS,0 m SRS,1 m SRS,2 mSRS,3 At least one of N0, N1, N2, and N3 is related to C_SRS. 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 of the hop within the sub-BWP; m SRS,0 m SRS,1 m SRS,2 m SRS,3 is used to determine the hop bandwidth within the sub-BWP; N0, N1, N2, and N3 are used to determine the number of hops within the sub-BWP; and b_hop is used to determine the total bandwidth of the frequency hopping within the sub-BWP, that is, the bandwidth in the column corresponding to B_SRS = b_hop in Table 1. Optionally, b_hop = 0.

[0176] In one 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.

[0177] In one embodiment, the terminal performs the frequency hopping transmission of the uplink signal within the sub-BWPs of the activated uplink BWP, comprising: within the activated uplink BWP, the terminal switches from one sub-BWP to another sub-BWP to perform the frequency hopping transmission of the uplink signal after the frequency hopping transmission of the uplink signal in the one sub-BWP is completed.

[0178] In this embodiment, the terminal needs to complete the frequency hopping transmission within the sub-BWP and then switch to a new sub-BWP to perform the frequency hopping transmission of the uplink signal, so as to minimize the number of switching. For example, the uplink signal is SRS, and one round of frequency hopping within the sub-BWP requires X times, the index of the sub-BWP is determined based on the formula floor(n_SRS / X), and the frequency hopping index within the sub-BWP is determined based on the formula mod(n_SRS,X), where n_SRS is the SRS frequency hopping count.

[0179] In one embodiment, the terminal performs the frequency hopping transmission of the uplink signal based on the order of the plurality of sub-BWPs; or the terminal performs the frequency hopping transmission of the uplink signal in the plurality of sub-BWPs in an interleaved manner.

[0180] The following will introduce the scheduling restrictions or collision rules introduced by the frequency hopping transmission of the uplink signal.

[0181] In one embodiment, the time domain location of the switching time is related to the time domain location 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.

[0182] In one embodiment, the method further comprises: the terminal transmits the first channel or signal based on a first rule, the first rule comprising at least one of:

[0183] 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.

[0184] 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.

[0185] N is the preparation time of the first channel or signal, and N is calculated based on the minimum 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 frequency hopping transmission of the uplink signal and the BWP of the first channel or signal transmission, and N and T are positive integers.

[0186] Specifically, taking the frequency hopping of SRS as an example.

[0187] For a SRS hop starting from symbol , and another channel or signal (such as PUSCH, PUCCH) starting from symbol N S , the UE considers the following when applying the dropping rule:

[0188] The interval between the last symbol of the PDCCH associated with the DCI and the SRS symbol contains at least N2 symbols and an additional time interval , where is the switching time between the SRS hop and the BWP (such as activeBWP) of the transmission of the other channel or signal.

[0189] The interval between the last symbol of the PDCCH associated with the DCI and the N S symbols of the colliding other channel or signal contains at least N2 symbols.

[0190] N2 is a PUSCH preparation time, and the calculation of N2 is based on the minimum SCS among the following: SRS hop, SCS of other channels / signals, SCS of PDCCH.

[0191] In one embodiment, the method further comprises: in case that the frequency hopping transmission of the uplink signal and the transmission of the second channel or signal overlap in a 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 a priority of the frequency hopping transmission of the uplink signal and the second channel or signal.

[0192] 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 discarded; 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 discarded.

[0193] To make the uplink signal frequency hopping transmission method provided by the embodiments of the present application more comprehensible, the following will be described in combination with several specific embodiments.

[0194] Embodiment one

[0195] Embodiment one mainly introduces the above scheme 1-1.

[0196] The implementation of scheme 1-1 is shown in Figure 5 , where the first-stage hop is a small dot-filled square, see Figure 6 SRS1 st stage hop 0, SRS1 st stage hop 1, SRS1 st stage hop 2, SRS1 st stage hop 3. Of course, the first-stage hop can also be expressed as 'hop' here.

[0197] Switching between two adjacent first-stage hops requires switching time. If the first first-stage hop is in the active uplink BWP frequency range, no switching time is required for the active uplink BWP and the first first-stage hop.

[0198] The second-stage hop is defined within each first-stage hop, and adjacent second-stage hops do not require switching time. As shown in Figure 3 , SRS1 st stage hop 0 contains four second-stage hops, which are SRS2 st stage hop 0, SRS2 stStage 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 2nd level hops.

[0199] Further, the frequency domain starting position offset of the 1st level hop The frequency domain starting position offset of the 2nd level hop within the 1st level hop is Wherein, n_shift is the offset relative to the common frequency domain reference point of the multiple 1st level hops (the frequency domain reference point is the starting point of the first BWP or the reference point A of the CC); n_offset is the offset relative to the frequency domain starting position of the corresponding 1st level hop.

[0200] 1) The following will introduce how to determine the frequency domain starting position offset of the 1st level hop

[0201] Wherein, the frequency domain starting position of the 1st level hop Can be determined according to the following formula (sequential frequency hopping pattern):

[0202]

[0203] Wherein, n_offset is the hop offset of the 1st hop, hop index (or hop counter) of each 1st level hop, N hop1 m is the number of 1st level hops, SRS,hop1 B is the bandwidth of the 1st level hop, SCS is the number of RBs.

[0204] Alternatively, considering the'staggered pattern' of the 1st level hop, it can be determined according to the following formula:

[0205]

[0206] Further,

[0207]

[0208] Optionally, It can be determined according to the time domain order of the 1st level hop, or according to the SRS frequency hopping count nSRS is determined. Where n SRS is the frequency hopping count including the 2nd level hop, if there is no 2nd level hop or no 2nd level hop configured,

[0209] Optionally, if the 2nd level hop is configured, then where N hop1 is the number of 2nd level hops included in the 1st level hop. Optionally, if there are X rounds of 2nd level hops in the 1st level hop, then

[0210] 2) The following will introduce how to determine the frequency domain starting position offset of the 2nd level hop

[0211]

[0212] where B SRS is the 2nd level hopping parameter used to determine the bandwidth of the 2nd level hop, b is the order of the 2nd level hopping, m SRS,b is the bandwidth corresponding to the bth order of the 2nd level hopping, and n b is the frequency domain position index.

[0213] Optionally, the bandwidth m SRS,0 corresponding to the 0th order of the 2nd level hopping is equal to or less than the bandwidth of the 1st level hop.

[0214] Optionally, b hop < B SRS ; optionally, when b hop < B SRS , the 2nd level hopping is enabled.

[0215] Further,

[0216]

[0217] where b hop is the 2nd level 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.

[0218] 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 SRS .

[0219] Optionally, if the 2nd level hop is configured, then where N hop2The number of the second level hops contained in the first level hop is 1. Optionally, if there are X rounds of the second level hops in the first level hop, then

[0220] Further,

[0221]

[0222] wherein N b The number of the narrow bands corresponding to the b-th order of the frequency hopping of the second level.

[0223] The frequency domain starting position offset (relative to the reference point A of the first BWP starting point or CC) of each second level hop can be determined according to the following formula:

[0224]

[0225] Optionally, the first level and second level hop parameters in the above formula can be determined according to the parameters described in the previous embodiment 1-1 and the frequency hopping table, etc.

[0226] Embodiment two

[0227] 1) For embodiment two, the frequency domain starting position offset of the hop can be determined according to the following formula:

[0228]

[0229] wherein, is the offset of n_shift PRBs relative to the common frequency domain reference point of the 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 the frequency hopping, m SRS,b is the bandwidth corresponding to the b-th order of the frequency hopping, n b is the frequency domain position index.

[0230] Further,

[0231]

[0232] wherein b hop is the frequency hopping parameter used to determine the total bandwidth of the hop, n SRS is the hop counter.

[0233] Further,

[0234]

[0235] wherein N b The number of the narrow bands corresponding to the b-th order of the frequency hopping.

[0236] Optionally, the parameters in the above formula can be determined by referring to the parameters of the above-mentioned Scheme 1-2 and the frequency hopping table, etc.

[0237] Furthermore, after determining the aforementioned hops, if a second-level hop is configured within each hop, the method for determining the second-level frequency hopping in Embodiment 1 can also be referred to. Optionally, the bandwidth corresponding to the 0th order of the second-level frequency hopping is equal to or less than the bandwidth of the first-level hop.

[0238] Furthermore, the implementation methods for determining whether adjacent hops need to switch time in Schemes 1-2 are as follows:

[0239] 1) By default, a time switch is required between adjacent hops, such as... Figure 7 As shown.

[0240] 2) Whether a switching time is needed between adjacent hops can be determined based on the frequency domain position of the adjacent hops.

[0241] In one example, the relationship between the hop and the active uplink BWP is used to determine whether a time switch is needed if the adjacent hop is within the active uplink BWP; otherwise, a time switch is needed.

[0242] like Figure 8 As shown, if SRS hop 1 and hop 2 are located within the active uplink BWP and their numberology is consistent with the active uplink BWP, then no switching time is required.

[0243] In one example, based on the frequency range relationship between adjacent hops, if the frequency range of adjacent hops does not exceed the terminal's maximum bandwidth capacity, then no handover time is required; otherwise, handover time is required.

[0244] like Figure 9 As shown, the frequency range of SRS hop 0, SRS hop 1, and SRS hop 2 does not exceed the terminal's maximum bandwidth capability and requires no switching time; however, a switching time is required between SRS hop 3 and SRS hop 2.

[0245] Optionally, the switching time between adjacent hops in the present invention can be determined based on the UE's capabilities.

[0246] In one example, a virtual BWP can be divided into blocks (such as sub-BWPs). If adjacent hops are located in the same sub-BWP, no time switching is required; otherwise, a time switching is required.

[0247] like Figure 10As shown, SRS hop 0, SRS hop 1, SRS hop 2 frequency range is located in sub-BWP 0, no switching time is needed; while SRS hop 3 and SRS hop 2 are located in different sub-BWPs, switching time is needed.

[0248] 3) Whether switching time is needed between adjacent hops can be determined according to network indication.

[0249] As shown, 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. As shown in the bitmap in Figure 10 ,

[0001] indicates that there is switching time between SRS hop 3 and SRS hop 2. Alternatively, the length of the bitmap is the number of hops, and bit 1 in the bitmap indicates that switching to the corresponding hop needs switching time. Alternatively, the length of the bitmap is hop number-1 (such as the first hop does not need switching time), and bit 1 in the bitmap indicates that switching to the corresponding hop needs switching time.

[0253] The time gap between hops will affect the current SRS resource symbol design, and the corresponding SRS resource pattern is as shown in Figure 12 . Among them, Figure 12 The left side of the existing SRS resource pattern, Figure 2 The right side is the SRS resource pattern design considering the time gap.

The gap duration can be obtained by subtracting the ‘symbol group interval’ from the ‘number of symbols of a symbol group’.

[0263] ‘Number of symbols of a symbol group’ (or duration of a symbol group) refers to the number of consecutive symbols contained in one symbol group.

[0264] Optionally, the number of symbols of a symbol group can be calculated by ‘repetition factor’.

[0265] For example, the repetition factor is the number of symbols in a symbol group.

[0266] Optionally, the number of symbols in different symbol groups within a slot is the same (regular case).

[0267] Optionally, the number of symbols in different symbol groups within a slot can be different (special case), and the number of symbols in a symbol group can include multiple (or a group).

[0268] One implementation: the number of symbols in a group of symbol groups includes two values, the first value is the number of symbols in the first symbol group, and the second value is the number of symbols in 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).

[0269] Optionally, the number of symbols in a symbol group can be calculated by the number of symbol groups.

[0270] Optionally, the number of symbols in a symbol group is equal to the number of symbols of the SRS resource within a slot / symbol group.

[0271] Optionally, the symbol sequence number in a symbol group is 0, 1, …, the number of symbols in the symbol group - 1.

[0272] Further, according to at least one of the above parameters, the mapping relationship between the symbol sequence number of the symbol in the SRS resource within the SRS resource and the symbol sequence number within the slot is obtained. Further, it can be determined according to the following parameters: l0, l', and Wherein, l0 is the starting symbol position of the SRS resource in a slot, l' is the symbol sequence number in the SRS resource, and is the number of symbols of the SRS resource within a slot.

[0273] The symbol l' in the SRS resource corresponds to the symbol position l within the slot (the symbol position within the slot can be applied to the actual SRS resource mapping, such as determining the relative RE offset corresponding to the symbol l'):

[0274]

[0275] in, The number of symbols in the symbol group. This refers to the gap duration.
