[0224] The first communication node is a communication node that transmits the measurement reference signal.

[0225] The invention is further described below in conjunction with specific embodiments. Specific embodiment 1

[0227] In this specific embodiment, the uplink measurement reference signal can be sent using time domain OCC, wherein the time domain OCC code is less than or equal to the frequency domain repetition transmission parameter R corresponding to the uplink measurement reference signal in a slot, wherein the frequency domain repetition transmission parameter R of the uplink measurement reference signal indicates that the frequency domain resources occupied by the measurement reference signal on R time domain symbols are the same, wherein the frequency domain resources include at least one of the following resources: frequency domain PRB, subcarriers in PRB.

[0228] Therefore, the base station needs to notify the terminal of the time domain OCC code used by the measurement reference signal. For example, a measurement reference signal includes a port, which may correspond to an OCC code as shown in Table 1. Table 1 is a schematic table 1 according to specific embodiment 1:

[0229] Table 1

[0230] Measurement reference signal port OCC Code Port 0 [1,1,1,1] Port 1 [1,-1,1,-1] Port 2 [1,1,-1,-1] Port 3 [1,-1,-1,1]

[0231] In Table 1, different OCC codes correspond to different ports, such as Figure 1 and Figure 2As shown, it is the mapping of OCC code to time domain symbol. Figure 1 is a schematic diagram of the mapping relationship between the time domain OCC code and the time domain symbol corresponding to port 0 according to the present invention, Figure 1 It is the mapping of the OCC code of port 0 to the time domain symbol. Figure 2 is a schematic diagram of the mapping relationship between the time domain OCC code and the time domain symbol corresponding to port 1 according to the present invention, Figure 2 It is the mapping of the OCC code of port 1 to the time domain symbol. At this time, the signaling may be used to notify the measurement reference signal port index, for example, SRS resource 1 includes port 0, and SRS resource 2 includes port 1. Although SRS resource 1 and SRS resource 2 both include one port, one corresponds to port 0 and the other corresponds to port 1. SRS resource 1 and SRS resource 2 may be SRS resources allocated to different terminals. Figure 1 and Figure 2 The four time domain symbols participating in the time domain OCC may be continuous time domain symbols or non-continuous time domain symbols, may be time domain symbols in one slot or may be time domain symbols in multiple slots.

[0232] In another implementation of this specific embodiment, the base station directly signals the OCC code index, one SRS resource corresponds to one OCC code, and multiple ports included in one SRS resource share one OCC code, as shown in Table 2, which is a schematic table 2 according to specific embodiment 1.

[0233] Table 2

[0234]

[0235]

[0236] For example, SRS resource 3 and SRS resource 4 are both resources including 4 SRS ports, SRS resource 3 corresponds to OCC code index 0, SRS resource 4 corresponds to code index 1, and the 4 SRS ports in SRS resource 3 share the time domain OCC code [1,1,1,1]. In another implementation of this specific embodiment, all SRS ports included in all SRS resources in an SRS resource set share a time domain OCC code index. Of course, this specific embodiment does not exclude that different SRS ports in an SRS resource use different time domain OCC codes.

[0237] In the above manner of this specific embodiment, the base station notifies the terminal of the time domain OCC code index used by SRS through signaling information, such as notifying the port index used by SRS in the signaling, or notifying the time domain OCC code index used by SRS. The base station can also further notify the length information of the time domain OCC code through signaling.

[0238] In another implementation of this specific embodiment, the base station may also agree with the terminal on a rule so that the terminal can obtain the above information through the agreed rule. For example, the terminal may obtain the OCC code index (or port index) used by the terminal through the SRS resource ID, such as the code index OCC of the time domain OCC index =(SRSID) mod T, where SRSID is the ID (Identification) of the SRS resource, and T is the total number of available OCC codes, or the length of the time domain OCC code. Similarly, the time domain OCC code index can be obtained through the SRS resource set ID (SRS resource group ID or SRS resource set ID) where the SRS resource is located, or the terminal identification number, such as C-RNTI.

[0239] In the present application, the uplink measurement reference signal may also be referred to as an uplink sounding reference signal. Specific embodiment 2

[0241] In this specific embodiment, the time domain OCC code of the SRS is associated with the SRS sequence.

[0242] Specifically, the length of the time domain OCC of the SRS is related to whether the SRS sequence changes with the time domain symbol, or whether the time domain OCC of the SRS is enabled is related to whether the SRS sequence changes with the time domain symbol. Or the length of the time domain OCC of the SRS is related to whether the SRS sequence parameter changes with the time domain symbol, wherein the SRS sequence parameter may be one or more of the following parameters: sequence group number, sequence number.

[0243] The length of the time domain OCC of the SRS is 1, which can also be called that the time domain OCC of the SRS is not enabled. The length of the time domain OCC of the SRS is greater than 1, which can also be called that the time domain OCC of the SRS is enabled.

[0244] When the length of the time domain OCC of the SRS is greater than 1, the sequence of the SRS is constant in the time domain symbol where the time domain OCC is located. When the length of the time domain OCC of the SRS is equal to 1, the sequence of the SRS is variable in the time domain symbol where the time domain OCC is located. And / or

[0245] When the length of the time domain OCC of the SRS is greater than 1, the sequence group number of the SRS is constant in the time domain symbol where the time domain OCC is located. When the length of the time domain OCC of the SRS is equal to 1, the sequence group number of the SRS is variable in the time domain symbol where the time domain OCC is located. And / or

[0246] When the length of the time domain OCC of the SRS is greater than 1, the sequence number of the SRS is constant in the time domain symbol where the time domain OCC is located. When the length of the time domain OCC of the SRS is equal to 1, the sequence number of the SRS is variable in the time domain symbol where the time domain OCC is located.

[0247] Specifically, the sequence of SRS in NR Obtained through the following formula:

[0248]

[0249] When time domain OCC is used, the reference signal sent on the SRS is obtained by the following formula:

[0250]

[0251] in is the sequence length of SRS, m is the number of PRBs occupied by SRS, δ is the total number of combs in the IFDMA (Interleaved Frequency Divisionn Multiple Access) mode used by SRS, α is the cyclic shift parameter, Belongs to {0,1} or is fixed to 0, w(l) is the element of the time domain OCC code on the time domain symbol l, or is called the phase scrambling factor of the time domain OCC code on the time domain symbol l.

[0252] Optional, when When it is fixed to 0, the above formula (1-0) is equivalent to:

[0253] In the present application, the sequence corresponding to the SRS is a set of symbols that the SRS needs to send before multiplying the time domain OCC code. For example, the multiple symbols that the SRS needs to send on multiple REs occupied by the SRS on a time domain symbol constitute the sequence, that is, Constitutes a sequence corresponding to SRS.

[0254] When the SRS sequence length Greater than ( is the number of subcarriers included in a PRB, such as in LTE and NR, When 12)

[0255]

[0256]

[0257]

[0258]

[0259] v is the sequence number, belonging to {0,1}, 0≤α≤2π, is less than or equal to Furthermore, when the number of PRBs occupied by SRS is less than 6, v is 0, otherwise v can be 0 or 1.

[0260] When the SRS sequence length Less than or equal to When

[0261]

[0262] in According to the sequence group number u, the predetermined table is searched and obtained.

[0263] Wherein u is the sequence group number, and u is obtained by the following formula:

[0264] u=(f gh (n s )+f ss )mod 30 (1)

[0265]

[0266] Where c(z) is the zth value in the Pseudo-random random sequence, given an initialization value c init , a random sequence can be generated. The initialization value in the sequence generation is in It is a parameter configured by a higher layer, or it may be a physical cell identification number.

[0267] The 31-length Pseudo-random sequence is generated in the following way:

[0268] c(n)=(x 1 (n+N C )+x 2 (n+N C ))mod 2

[0269] x 1 (n+31)=(x 1 (n+3)+x 1 (n))mod 2

[0270] x 2 (n+31)=(x 2 (n+3)+x 2 (n+2)+x 2 (n+1)+x 2 (n))mod 2

[0271] n=0,1,...,M PN -1,N C =1600,x 1 (0) = 1, x 1 (n)=0,n=1,2,...,30,

[0272] In formula (2), h() is a function of a time parameter, so that a sequence group number corresponding to a measurement reference signal port or a measurement reference signal resource will change with the time domain symbol.

[0273] However, when SRS needs to use time domain OCC orthogonality, so that two SRS resources 1 and SRS resources 2 that have partial overlap in the frequency domain are orthogonal, Figure 3 is a schematic diagram of orthogonalizing two SRS resources partially overlapping in the frequency domain through time domain OCC according to the present invention, as Figure 3 As shown, in order to make the ports in SRS resource 1 and the ports in SRS resource 2 orthogonal, time domain OCC can be used. Since the sequences corresponding to the overlapping parts of SRS resource 1 and SRS resource 2 are different, in order to be orthogonal, SRS resource 1 needs to use the same sequence on the two time domain symbols where the time domain OCC is located, and SRS resource 2 also needs to use the same sequence on the two time domain symbols where the time domain OCC is located. Therefore, the sequence group number u needs to remain unchanged on the time domain symbol where the time domain OCC is located.

[0274] That is, the h() function does not include the time domain symbol index, or the h() function takes the same value for multiple time domain symbols of the time domain symbol where the time domain OCC is located.

[0275] Thus, the base station and the terminal may agree that when the length of the time domain OCC is greater than 1, the acquisition parameter of h() does not include the time domain symbol index, and when the length of the time domain OCC is 1, the acquisition parameter of h() includes the time domain symbol index. Or the base station and the terminal agree that when the length of the time domain OCC is greater than 1, the time jump of the sequence group number u is not enabled, and when the length of the time domain OCC is 1, the time jump of the sequence group number u is enabled. Or the base station and the terminal may agree that when the length of the time domain OCC is greater than 1, the value of h() is the same on multiple time domain symbols where the time domain OCC is located, and when the length of the time domain OCC is equal to 1, the value of h() may be different on multiple time domain symbols where the time domain OCC is located.

[0276] Similarly, for example, the serial number v is obtained by the following formula: When the sequence number jump is enabled, v = c(z 1 ), the base station can agree with the terminal that when the length of the domain OCC is greater than 1, z 1 The acquisition parameters do not include the time domain symbol index. When the length of the time domain OCC is equal to 1, z 1 The acquisition parameters include the time domain symbol index. Or the base station and the terminal agree that when the length of the time domain OCC is greater than 1, the time jump of the sequence number v is not enabled, and when the length of the time domain OCC is 1, the time jump of the sequence number v is enabled. Or the base station and the terminal may agree that when the length of the time domain OCC is greater than 1, on multiple time domain symbols where the time domain OCC is located, z 1 The value of is the same. When the length of the time domain OCC is equal to 1, on multiple time domain symbols where the time domain OCC is located, z 1 The value of can be different.

[0277] In the above implementation manner, the time domain OCC code length is related to the sequence, or the time domain OCC code set is related to the sequence. For example, when the terminal and the base station agree that the time domain OCC code belongs to set 1 = {(1,1,1,1)}, the acquisition parameters of h() include the time domain symbol index, or the hopping of the sequence group number u over time is enabled, or the values ​​of h() on the four time domain symbols where the time domain OCC is located may be different; when the time domain OCC code belongs to set 2 = {(1,-1,1,-1), (1,1,-1,-1), (1,-1,-1,1)}, the acquisition parameters of h() do not include the time domain symbol index, or the hopping of the sequence group number u over time is not enabled, or the values ​​of h() on the four time domain symbols where the time domain OCC is located need to be the same.

[0278] Similarly, the code set of the time domain OCC may be related to the sequence number v. For example, when the terminal and the base station agree that the time domain OCC code belongs to the set 1 = {(1,1,1,1)}, z 1 The acquisition parameters include the time domain symbol index, or the sequence number v jump enable over time, or z 1 The values ​​of the four time domain symbols where the time domain OCC is located can be different. When the time domain OCC code belongs to the set 2 = {(1,-1,1,-1), (1,1,-1,-1), (1,-1,-1,1)}, z 1 The acquisition parameters do not include the time domain symbol index, or the sequence number v is not enabled to jump over time, or z 1 The values ​​of the four time domain symbols where the time domain OCC is located need to be the same.

[0279] The above division of the time domain OCC code set 1 and the time domain OCC code set 2 is only an example, and other division methods are not excluded. In short, there is a correlation between the time domain code set and the sequence generation mode, or there is a correlation between the time domain code set and the sequence parameters. Specific embodiment 3

[0281] In this specific embodiment, when the uplink reference signal adopts a time domain OCC code, the length of the time domain OCC satisfies at least one of the following characteristics:

[0282] Feature 1: The length of the time domain OCC code corresponding to the measurement reference signal is less than or equal to the frequency domain repetition transmission parameter R corresponding to the measurement reference signal, wherein the frequency domain repetition transmission parameter is the number of time domain symbols included in the unit of frequency domain hopping of the measurement reference signal in one time unit. Figure 4 is a schematic diagram of the frequency domain repetition transmission parameter R of the SRS according to the present invention being 2, such as Figure 4 In the above, a measurement reference signal port occupies 4 symbols in a slot, the frequency domain resources occupied by the first two time domain symbols are the same, the frequency domain positions occupied by the last two time domain symbols are the same, the frequency domains occupied by the first two time domain symbols and the last two time domain symbols are different, such as the occupied PRBs are different, but the occupied combs in IFDMA (Interleaved Frequency Division Multiple Access) can be the same. Figure 4 The repetition transmission parameter R in the mid-frequency domain indicates that the frequency domain resources (frequency domain resources include frequency domain physical resource blocks PRB and frequency domain subcarriers) occupied by the measurement reference signal on R time domain symbols in a time unit remain unchanged, and may also indicate that the measurement reference signal performs a frequency domain hop after every R time domain symbols (i.e., the measurement reference signal is sent on R time domain symbols), and the R time domain symbols may be located in different slots or in the same time unit. The frequency domain resources include at least one of the following resources: PRB (physical resource block, PRB for short), subcarriers in PRB, and subcarriers.

[0283] Feature 2: The length of the time domain OCC code corresponding to the measurement reference signal is less than or equal to the repetition parameter R5 of the measurement reference signal sequence. Figure 5 is a schematic diagram of the SRS sequence repetition transmission parameter R5 being 2 according to the present invention, as shown in Figure 5As shown, an SRS port occupies 4 time domain symbols in one slot, and the same sequence is used in the first two time domain symbols, that is, the symbols used by the SRS on the same subcarrier in the first two time domain symbols are the same (for example, the symbol of the SRS on the first subcarrier before the time domain OCC is a1, that is, the symbol in the formula (1-0) on the RE a1), the same sequence is used in the last two time domain symbols, that is, the symbols used for SRS on the same subcarrier in the last two time domain symbols are the same, so that the sequence repetition parameter R5 of the SRS reference signal is equal to 2, so that the time domain OCC can only be mapped on the first two time domain symbols, or mapped on the last two time domain symbols, so that the length of the time domain OCC is less than or equal to 2. Figure 6 is a schematic diagram of the SRS sequence repetition transmission parameter R5 being 4 according to the present invention, as shown in Figure 6 In the above, one SRS port occupies 4 time domain symbols in one slot, and the same sequence is used in these 4 time domain symbols, that is, the symbols used by the SRS on the same subcarrier in these 4 time domain symbols before the time domain OCC code are the same, so that the sequence repetition parameter R5 of the SRS reference signal is equal to 4. Therefore, the length of the time domain OCC can be less than or equal to 4. Figures 5-6 In this embodiment, an SRS port occupies 4 time domain symbols in one slot. In this embodiment, the sequence repetition parameter R5 for obtaining the SRS can also be across slots. Figure 7 is a schematic diagram of a sequence repetition transmission parameter R5 of an SRS according to the present invention being 4 and a sequence repetition transmission unit including time domain symbols in more than one slot, that is, Figure 7 As shown, the sequence repetition parameter R5 of the SRS is 4. The sequence repetition parameter R5 can also be referred to as the number of time domain symbols of sequence hopping. The sequence repetition parameter R5 can also be referred to as the relationship between the SRS sequence and the time domain symbol.

[0284] Feature 3: The length of the time domain OCC code includes length 1. The length of the time domain OCC equal to 1 can also be called time domain OCC disabled. In this application, the length of the time domain OCC code belongs to {1, 2, 4}, or the length of the time domain OCC code belongs to {1, 2, 4, 8}.

[0285] Feature 4: There is a correlation between the length of the time domain OCC code and the sequence parameter of the measurement reference signal. For example, when the length of the time domain OCC is greater than 1, the sequences corresponding to the R1 time domain symbols occupied by an SRS port in a time unit are the same; and / or when the length of the time domain OCC is greater than 1, the R1 time domain symbols occupied by an SRS port in a time unit correspond to the same sequence group number (the sequence group number is the u described in the specific embodiment 1); when the length of the time domain OCC is greater than 1, the R1 time domain symbols occupied by an SRS port in a time unit correspond to the same sequence number (the sequence number is the v described in the specific embodiment 1); when the sequences corresponding to the R1 time domain symbols occupied by an SRS port in a time unit are different, the length of the time domain OCC code corresponding to the measurement reference signal port is 1; when the sequence group numbers corresponding to the R1 time domain symbols occupied by an SRS port in a time unit are different, the length of the time domain OCC code corresponding to the measurement reference signal port is 1; when the sequence numbers corresponding to the R1 time domain symbols occupied by an SRS port in a time unit are different, the length of the time domain OCC code corresponding to the measurement reference signal port is 1;

[0286] The R1 satisfies at least one of the following characteristics: R1 is less than or equal to R, R1 is the length of the time domain OCC code, and R1 is less than or equal to N, where N is the number of time domain symbols included in one measurement reference signal port in one time unit.

[0287] In the above specific embodiment, the R1 time domain symbols are in one time unit, such as in one slot. Of course, this specific embodiment does not exclude that the R1 time domain symbols may include time domain symbols in multiple time units, such as the R1 time domain symbols include time domain symbols in more than one slot. Specific embodiment 4

[0289] In this specific embodiment, the base station sends signaling information to the terminal, and the signaling information includes at least one of the following information: correspondence information between the sequence and the time domain symbol, and the time domain OCC code corresponding to the time domain symbol set, wherein the time domain OCC code corresponding to the time domain symbol set can also be called the phase scrambling factor corresponding to the time domain symbol in the time domain symbol set.

[0290] The correspondence information between the sequence and the time domain symbol includes at least one of the following information: information on whether the sequence parameter changes on R2 time domain symbols in a time unit; information on whether the sequence changes on R2 time domain symbols in a time unit; the sequence jumps once after every R3 time domain symbols (i.e., the sequence jumps once after the R3 time domain symbols occupied by the measurement reference signal); the sequence parameter jumps once after every R3 time domain symbols (i.e., the sequence parameter jumps once after the R3 time domain symbols occupied by the measurement reference signal); wherein the sequence parameter is used to generate the sequence, for example, the sequence parameter includes one or two of the following parameters: sequence group number (such as parameter u described in specific embodiment 1), sequence number (such as parameter v in the specific embodiment). In short, the sequence parameter jumps once after the R3 time domain symbols occupied by the channel or signal, wherein the R3 time domain symbols can be in one time unit or in multiple time units, wherein one time unit can be a slot or a subframe, and of course other time units are not excluded. It should be supplemented that the time domain OCC code corresponding to the time domain symbol set can also be called a phase scrambling factor corresponding to the time domain symbol in the time domain symbol set.

[0291] Further, the R2 or R3 satisfies at least one of the following characteristics: less than or equal to R, which is the length of the time domain OCC code corresponding to the channel or signal of the signaling, and less than or equal to N, where N is the number of time domain symbols included in a time unit of the channel or signal, and the channel or signal is the channel or signal corresponding to the signaling information. The R2 and R3 may also be referred to as sequence repetition parameters, sequence hopping parameters, or other equivalent names, which do not affect the creativity of this patent.

[0292] The sequence is transmitted on the following channels or signals: control channel, data channel, sounding reference signal, demodulation reference signal. In order to achieve orthogonalization between SRS (Sounding reference signal, referred to as SRS) and control channel, time domain OCC can be used, so it is necessary to notify the time domain OCC information used for the control channel and the time domain OCC code used for SRS. Similarly, the time domain OCC code index used for the data channel can be notified, and the time domain OCC code index used for the demodulation reference signal can also be notified.

[0293] Further: the time domain OCC code corresponding to the time domain symbol in the time domain symbol set is characterized in that: the signal corresponding to the channel or signal of the signaling information transmitted on the time domain symbol in the time domain symbol set is multiplied by the time domain OCC code before being transmitted.

[0294] When the channel or signal corresponding to the signaling information is the same as the signal transmitted on the time domain symbol in the time domain symbol set, the signal is multiplied by the time domain symbol OCC code and then transmitted. For example, in order to achieve orthogonality between the uplink control channel and the SRS on the same frequency domain resources, the time domain OCC code can be used, but because the sequences used by the uplink control channel and the SRS are different, it is necessary that the uplink control channel has the same corresponding transmission sequence on the time domain symbol set corresponding to the time domain OCC code, and the sequence used by the SRS has the same corresponding transmission sequence on the time domain symbol set corresponding to the time domain OCC code.

[0295] In this specific embodiment or in this application, the sequence is composed of symbols of the information sent on the channel or signal before being multiplied by the time domain OCC code, for example, multiple REs on a time domain symbol multiplied by multiple symbols before the OCC code constitute the sequence. Specific embodiment 5

[0297] In this specific embodiment, the code domain information of the SRS changes once every F time domain symbols, wherein the code domain information includes at least one of the following information: the time domain OCC code of the SRS, sequence parameters, and port index. Wherein F is a positive integer greater than or equal to 1, wherein the F time domain symbols include the SRS, that is, the time domain symbols not including the SRS are not calculated in the F, wherein the sequence parameters are used to generate the sequence, for example, when the SRS adopts the ZC or predetermined sequence in formula (1-1) or formula (1-0), the sequence parameters include at least one of the following parameters: sequence group number u, sequence number v, cyclic shift

[0298] Further, code domain information of the measurement reference signal is obtained according to the first information, wherein the first information includes at least one of the following information: a measurement reference signal resource ID where the measurement reference signal is located, such as Portindex=(SRSID)mod T, where SRSID represents the SRS resource ID where the SRS is located; the number N of time domain symbols contained in the time unit where the measurement reference signal is located, such as 14 time domain symbols included in a slot, that is, N=14, if a slot includes 12 time domain symbols, then N=12, of course, this embodiment does not exclude the number of time domain symbols included in a slot is other cases; integer M; the number L of time domain symbols occupied by the measurement reference signal in a time unit, such as L is the number of time domain symbols occupied by a measurement reference signal in a slot, and L belongs to {1,2,4}; index information l of the time domain symbol where the measurement reference signal is located in the N time domain symbols contained in a time unit. 2 The index information l of the time domain symbol where the measurement reference signal is located in the preset M time domain symbols1 ; The index information l of the measurement reference signal in the L time domain symbols 0 , the frame number of the frame where the measurement reference signal is located; the number of time units B contained in the frame where the measurement reference signal is located; the time unit index obtained according to the subcarrier spacing of the BWP (Bandwidth part) where the measurement reference signal is located; a random sequence with a length of D; a virtual cell number The frequency domain repetition sending parameter R corresponding to the measurement reference signal, the sequence repetition sending parameter R5 corresponding to the measurement reference signal, and the F.

[0299] Optionally, the index information i , i=1,2 can be obtained by the following formula in is the index information of the starting time domain symbol occupied by the measurement reference signal in a time unit in the time unit, is the index information of the starting time domain symbol occupied by the measurement reference signal in the preset M time domain symbols, l'=0,1,...,L-1 is the index information of the time domain symbol occupied by the measurement reference signal in the L time domain symbols. For example, an SRS measurement reference signal port or an SRS measurement reference signal resource occupies 4 time domain symbols with indexes {9,10,11,12} in a slot, then is 9, =1, where it is assumed that the M preset time domain symbols are time domain symbols with indexes {8, 9, 10, 11, 12, 13} in a slot, that is, the M preset time domain symbols are the last 6 time domain symbols in a slot. At this time, l'=0, 1, 2, 3.

[0300] Wherein, the M satisfies the following conditions: less than or equal to the N, and greater than or equal to A; wherein, the A is the maximum number of time domain symbols that the measurement reference signal is allowed to occupy in a time unit, for example, the SRS in the NR can occupy the last 6 time domain symbols in a slot, then A is 6 or M is 6, or the A is the number of time domain symbols occupied by the measurement reference signal in a time unit, for example, the time domain symbols occupied by an SRS resource in a slot belong to {1,2,4}, that is, A belongs to {1,2,4}. The frequency domain repetition transmission parameter R indicates that the frequency domain resources occupied by the measurement reference signal on the R time domain symbols in a time unit remain unchanged, wherein the frequency domain resources include at least one of the following resources: PRB resources, RE (resource element, also called subcarrier) in the PRB, for example, the measurement reference signal occupies the same PRB on the R time domain symbols, but the subcarriers in the occupied PRB can be different, or the measurement reference signal occupies the same PRB on the R time domain symbols, and the subcarriers in the occupied PRB are also the same. Or the frequency domain repetition transmission parameter R indicates that after the R time domain symbols occupied by the measurement reference signal, the frequency domain resource corresponding to the measurement reference signal jumps, and the R time domain symbols can be located in one slot or in multiple slots.

[0301] Furthermore, the time domain OCC code index or port index used by the SRS is obtained by one of the following formulas:

[0302]

[0303]

[0304] Wherein g(X) is a function of X, X is the first information, Portindex represents the port index corresponding to the measurement reference signal, or is the OCC code index corresponding to the measurement reference signal. T is one of the following information: the length of the time domain OCC code, the total number of time domain OCC codes available for SRS, the total number of different ports of SRS, the frequency domain repetition transmission parameter R of the measurement reference signal, and the sequence repetition parameter R5 of the measurement reference signal. c(z) represents the zth value of a randomized sequence, w 0 ∈{0,1,...T-1} is a predetermined value, or w 0 Included in the received signaling information. 1 is an integer greater than or equal to 1. For example, D 1 =8, F is R, or R5, or the minimum value of R and R5.

[0305] Similarly, the cyclic shift parameter of SRS (the cyclic shift parameter is α in formula (1-1) or formula (1-0), such as the ith measurement reference signal port ) can also change over time. For example, the cyclic shift corresponding to SRS Obtained by one of the following formulas:

[0306]

[0307]

[0308] And / or the sequence group number u is obtained by one of the following formulas:

[0309]

[0310]

[0311] And / or the serial number v is obtained by one of the following formulas:

[0312] v = c(g(X));

[0313]

[0314] Wherein g(X) is a function of X, and X is the first information. is the number of measurement reference signal ports included in an SRS resource, is a conventional value, indicating the maximum number of cyclic shifts, or the total number of different cyclic shifts available, belonging to {8,12} or {8,24}, c(z) represents the zth value of a randomized sequence. is a predetermined value, or Included in the received signaling information. 2 is an integer greater than or equal to 1. The C is the total number of sequence groups, for example, 30. ss It is obtained according to agreed rules and / or parameters included in the received signaling information, such as

[0315] The F is equal to the R, or equal to the R5, or equal to the minimum of the R and the R5. It should be noted that the sequence group number u, sequence number v, cyclic shift It can correspond to different F values ​​or the same F value.

[0316] For example, c(z) is a PN sequence, and its initialization value is about function.

[0317] Furthermore, g(X) is one of the following formulas:

[0318] g(l 1 ,M,n s )=l 1 +n s *M,

[0319] g(l 1 ,M,n s ,n f )=l 1 +n s *M+B*n' f *M;

[0320] g(l 2 ,N,n s )=l 2 +n s *N;

[0321] g(l 2 ,N,n s ,n f )=l 2 +n s *N+B*n' f *N;

[0322] g(l 0 ,L,n s )=l 0 +n s *L;

[0329]

[0330] The said n' f =n f Or n' f =n f mod(E), where the said nf is the frame number of the frame where the reference signal is located, and E is a predetermined value. Specific embodiment 6

[0332] In this specific embodiment, the terminal determines the parameters of the sounding reference signal according to the agreed constraint conditions; and uses the parameters to transmit the sounding reference signal.

[0333] Furthermore, the parameter is a frequency hopping parameter of the SRS.

[0334] Furthermore, the SRS is a measurement reference signal triggered by physical layer dynamic signaling, such as a non-periodic SRS.

[0335] Furthermore, the predetermined constraint condition is at least one of the following conditions:

[0336] Condition 1: The frequency domain resources occupied by the measurement reference signal in one time unit are continuous, Figure 8 is a schematic diagram showing that the frequency domain position occupied by the SRS in one slot according to the present invention is the union of the frequency domain positions occupied by the SRS in multiple time domain symbols in one slot, such as Figure 8 As shown, an SRS resource occupies 4 time domain symbols in one slot, and the frequency domain resources occupied in each time domain symbol are different, for example, the frequency domain PRB (Physical resource Block) occupied in each time domain symbol is different, so that the frequency domain resources occupied by the SRS in one slot are the union of the frequency domain resources occupied by the SRS in 4 time domain symbols, such as Figure 8 As shown, this constraint condition is that the frequency domain resources occupied by SRS in one slot are continuous, there is no non-continuous frequency band in the middle, and the frequency domain resources are in units of PRB.

[0337] Condition 2: the frequency domain subcarriers occupied by the measurement reference signal in one time unit are evenly distributed on the frequency domain resources occupied by the measurement reference signal in one time unit;

[0338] Condition 3: The frequency domain resource occupied by the measurement reference signal in one time unit is a frequency hopping bandwidth, where the frequency hopping bandwidth is determined by parameter b hopDetermine, Figure 9(a) is a schematic diagram of a bandwidth in the third level bandwidth in the SRS tree structure according to the present invention. As shown in Figure 9(a), the bandwidth of SRS is represented by a tree-like structure, or a tree is called a multi-level bandwidth structure. In the tree structure, a bandwidth of the nth level includes one or more bandwidths of the n+1th level. In Figure 9(a), the bandwidth of the previous level includes two bandwidths of the next level. As shown in Figure 9(a), a bandwidth in the shaded part of the figure has corresponding bandwidth indexes of 0, 1, 1, 0 in each level of bandwidth b=0, 1, 2, 3. Figure 9(b) is a schematic diagram of a bandwidth in the second level bandwidth in the SRS tree structure according to the present invention. A bandwidth in the shaded part of Figure 9(b) has corresponding bandwidth indexes of 0, 0, 1 in each level of bandwidth b=0, 1, 2. Frequency hopping bandwidth parameter b hop The frequency domain range used to represent the frequency hopping of SRS, that is, the union of the frequency domain positions occupied by SRS in each time domain symbol belongs to b hop One of the bandwidths in the frequency hopping bandwidth. Or it can also be called the frequency hopping bandwidth parameter b hop The frequency hopping bandwidth level set of SRS is obtained as {b hop +1,b hop +2,...,B SRS}, FIG. 10(a) is a frequency hopping bandwidth level b according to the present invention. hop = 1, FIG10(b) is a schematic diagram of the frequency hopping bandwidth level b according to the present invention. hop Schematic diagram of =2.

[0339] Condition 4: The frequency domain resource occupied by the measurement reference signal in one time unit is one BWP;

[0340] Condition 5: The frequency domain resource occupied by the measurement reference signal in a time unit is the maximum bandwidth in the multi-level bandwidth structure, for example, the frequency domain resource occupied by SRS in a slot is m SRS,0 A bandwidth is determined, where m SRS,0 A corresponding bandwidth is shown in FIG. 10( a ) or FIG. 10( b ), and may also be referred to as a bandwidth corresponding to the maximum bandwidth in the tree structure.

[0341] Condition 6: The frequency hopping bandwidth level of the measurement reference signal is an agreed value, such as the b corresponding to the non-periodic measurement reference signal. hop =0;

[0342] Condition 7: The parameters of the measurement reference signal satisfy the formula: or Where b is the bandwidth level information in the multi-level bandwidth structure, b hopA is a frequency hopping bandwidth level set, that is, SRS belongs to level b in the tree structure hopAIn the bandwidth level of b, its bandwidth index will change over time. hopA The bandwidth index of a bandwidth level does not change over time. s is the number of time domain symbols occupied by the measurement reference signal in a time domain, and R is the frequency domain repetition transmission parameter of the measurement reference signal. The multi-level bandwidth structure includes multiple bandwidth levels, and a bandwidth in the b-1th level bandwidth includes N in the bth level bandwidth. b Bandwidth, such as Figure 10(a) to Figure 10(b) As shown, N 0 =1,N 1 =2,N 2 =2,N 3 =2. The bandwidth index occupied by the SRS in a frequency hopping bandwidth level changes with time. Specifically, the frequency domain starting position k occupied by the SRS 0 It can be obtained by the following formula: in n shift is a high-level configuration parameter, k TC is the index of the comb where SRS is located when SRS is transmitted using IFDMA, K TC It is the total number of SRS combs when SRS is transmitted using IFDMA.

[0343]

[0344]

[0345]

[0346] From the above formula, it can be seen that when the bandwidth level belongs to b hopA When SRS corresponds to the bandwidth index n at this bandwidth level b It changes with time. When the bandwidth level does not belong to b hopA , the bandwidth index n corresponding to the SRS at this bandwidth level b Does not change over time, RRC It is a high-level configuration parameter.

[0347] It should be noted that if N b is equal to 1, then the bandwidth index n b It will not change with time and can be regarded as a special case of change with time.

[0348] Furthermore, when the frequency hopping bandwidth is {b hop +1,b hop +2,...,B SRS}, the above formula can be updated as follows:

[0349]

[0350]

[0351] In the above formula, for b'=b hop When N is fixed b' =1.

[0352]

[0353] Since the configuration parameters of SRS need to meet Thus, only the first parameter set information of SRS can be configured, and the second parameter set information can be configured by the parameter configuration and constraint conditions in the first parameter set. Get, for example, for (C SRS ,B SRS ,b hopA ,N s ,R)These 5 parameters can only be configured partially, and the remaining parameters are based on the configured parameters and Get, for example, configuration (C SRS ,B SRS ,N s ,R), the terminal further Get b hopA , or configure (C SRS ,B SRS ,b hopA ,R), the terminal further Get N s , or configure (C SRS ,b hopA ,N s ,R), the terminal further Get B SRS For the constraints When b hopA = {b hop +1,b hop +2,...,B SRS}, this constraint can be updated as: or Or this formula can be equivalent to: For b=b hop When N is fixed b =1), then parameter b hopA You only need to know b hopIn short, the second parameter set of SRS is determined according to the first parameter set of SRS and the predetermined constraint condition. The first parameter set and / or the second parameter set meet at least one of the following characteristics: the first parameter set is included in the received signaling information; the second parameter set is not included in the received signaling information; the second parameter set includes the bandwidth information occupied by the measurement reference signal on a time domain unit, such as B SRS , the intersection between the first parameter set and the second parameter set is empty; the first parameter set includes at least one of the following parameters: a multi-level bandwidth structure index, such as C SRS , where C SRS Indicates selecting one of the multiple tree structures to measure the bandwidth level information occupied by a time domain unit of the reference signal, such as B SRS , measure the frequency hopping bandwidth level information of the reference signal, such as the above b hopA or b hop , measure the number of time domain symbols occupied by the reference signal in a time unit, such as N s , measuring the repetition transmission parameter of the reference signal in a time unit, such as R. The second parameter set includes at least one of the following parameters: a multi-level bandwidth structure index, such as C SRS , where C SRS Indicates selecting one of the multiple tree structures to measure the bandwidth level information occupied by a time domain unit of the reference signal, such as B SRS , measure the frequency hopping bandwidth level information of the reference signal, such as the above b hopA or b hop , measure the number of time domain symbols occupied by the reference signal in a time unit, such as N s , measure the repetition parameter of the reference signal in a time unit, such as R.

[0354] It should be noted that if multiple second parameter values ​​are obtained according to the first parameter set of SRS and the predetermined constraints, that is, multiple second parameter values ​​satisfy the constraints, then one of the second parameter values ​​is selected from the multiple second parameter values ​​according to the agreed rules, such as selecting the minimum value from the multiple second parameter values, or selecting the maximum value.

[0355] Further, the terminal and the base station agree that the parameter configuration of the SRS meets the agreed conditions, or the terminal does not want to receive the SRS parameter configuration that does not meet the agreed conditions. If the terminal receives the SRS parameter configuration that does not meet the agreed conditions, the terminal considers that the control information is decoded incorrectly, or the terminal does not send the SRS. Or when receiving the SRS parameter configuration that does not meet the agreed constraint conditions, the terminal sends a predetermined indication information to the upper layer or the base station. Specific embodiment 7

[0357] In this embodiment, the total number of available cyclic shifts of SRS is described. As in formula (3-1) or (3-2), When the total number of IFDMA combs is 4, When the total number of IFDMA combs is 2, is 24, or when the total number of IFDMA combs is 2, Belongs to {8,24}, whether {8,24} is obtained through signaling information or agreed rules. The total number of IFDMA combs is 2 δ , where δ is the length determination parameter of SRS in formula (1-0) or (1-1) 2 of 2 δ . Specific embodiment 8

[0359] In this embodiment, there is a correlation between PTRS (Phase-tracking reference signal) and SRS.

[0360] Specifically, when the terminal receives the time domain OCC enable of the SRS, or the time domain OCC code of the SRS belongs to a predetermined set, the terminal does not send the PTRS.

[0361] Or when the terminal is configured to send PTRS under a predetermined condition (for example, when the modulation order of PUSCH is greater than a predetermined value), the time domain OCC of SRS is not enabled, or the time domain OCC code of SRS belongs to a predetermined set.

[0362] By adopting the technical solution of the above-mentioned specific embodiment, the uplink measurement reference signal SRS (Sounding Reference Signal, referred to as SRS) adopts the time domain OCC, which does not affect the coverage of the uplink measurement reference signal, and at the same time can increase the capacity of the measurement reference signal in a cell, and can solve the non-orthogonality problem caused by the two partial frequency domain overlaps of the SRS when the SRS is transmitted based on the ZC sequence. At the same time, in this application, the relationship between the time domain OCC code and the SRS and the time domain symbol is associated.

[0363] The time domain OCC, cyclic shift parameter or port index of the measurement reference signal is changed over time, which reduces signaling information and reduces inter-cell interference, thereby increasing the capacity of the measurement reference signal in the cell to a certain extent.

[0364] The frequency hopping bandwidth of the measurement reference signal needs to meet certain constraints, so that the terminal obtains parameter information of the measurement reference signal according to the constraints.

[0365] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention. Specific embodiment 9

[0367] This embodiment provides a method for obtaining channel quality of a measurement reference signal, including:

[0368] Determine BWP (Bandwidth part);

[0369] Obtaining a transmission parameter hypothesis of a control channel according to the parameters of the BWP;

[0370] The channel quality information of the measurement reference signal is obtained according to the transmission parameter assumption of the control channel.

[0371] The BWP parameter or the transmission parameter includes at least one of the following parameters: subcarrier spacing, CP (Cyclic prefix) length, and frequency domain position in a carrier frequency.

[0372] Optionally, the BWP information is determined according to one of the following methods:

[0373] Determine the BWP according to the BWP where the frequency domain resources occupied by the measurement reference signal are located;

[0374] Determine the BWP according to the BWP information in the configuration information of the measurement reference signal;

[0375] The BWP is determined according to the agreed BWP; wherein the agreed BWP may be, for example, a default DLBWP (default downlink BWP) or an initial active BWP (initial active BWP).

[0376] The BWP is determined according to the BWP where the control channel resource corresponding to the sounding reference signal is located.

[0377] Optionally, the measurement reference signal includes at least one of the following: CSI-RS (channel state information reference signal), DMRS (Demodulation reference signal), SSB (Synchronization signals block) synchronization signal.

[0378] Specifically, for example, the terminal detects the CSI-RS resource, predicts and / or detects the performance of the PDCCH (Physical Downlink control channel) when the beam corresponding to the CSI-RS resource is transmitted, and reports predetermined information to the base station when the performance is lower than a predetermined threshold. For example, when the BLER (Block error ratio) of the predicted PDCCH is higher than 10%, the beam recovery request information is reported to the base station.

[0379] In order to obtain the predicted BLER of PDCCH (also called Hypothetical PDCCH BLER), it is necessary to make assumptions on the transmission parameters of PDCCH, wherein the transmission parameters include at least one of the following parameters: subcarrier spacing, CP length, and frequency domain bandwidth in a carrier frequency, that is, assuming that the PDCCH is transmitted using the transmission parameters to obtain the predicted BLER. In order to obtain the transmission parameter hypothesis of PDCCH, BWP can be determined first, and the parameters of the determined BWP can be used as the transmission parameter hypothesis of PDCCH.

[0380] Obtain the BWP in one of the following ways:

[0381] Acquire the BWP according to the BWP where the frequency domain resources occupied by the CSI-RS are located;

[0382] The BWP is acquired according to the BWP information configured in the configuration information of the CSI-RS; for example, a BWP information may be configured in the CSI-RS resource setting in the NR, and the BWP information indicates the BWP where all CSI-RS resources included in the CSI-RS resource setting are located, wherein one CSI-RSresource setting includes one or more CSI-RS resource sets, and one CSI-RS resource set includes one or more CSI-RS resources;

[0383] According to the agreed BWP, the BWP is acquired; wherein the agreed BWP may be, for example, a default DL BWP (default downlink BWP) configured in the NR, or an initial active BWP (initial active BWP).

[0384] The BWP is obtained according to the BWP where the control channel resource corresponding to the measurement reference signal is located; for example, there is a QCL (qual-co-location) relationship between the CSI-RS and the DMRS of CORESET (control resource set) 1, and the parameters of the BWP where CORESET1 is located are used to obtain the transmission parameter hypothesis of the PDCCH.

[0385] The CP length may also be referred to as a CP type.
