[0058] The wireless communication 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.

[0059] FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application, as shown in FIG. 2, the wireless communication method 200 can include at least part of the following contents:

[0060] S210, the terminal sends a first SRS to a network side device; wherein the first SRS is obtained by multiplying at least two SRS symbol groups by corresponding orthogonal sequences; wherein the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups jump in one orthogonal sequence group, or the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups jump in different orthogonal sequence groups;

[0061] S220, the network side device receives the first SRS from the terminal.

[0062] It should be understood that FIG. 2 shows steps or operations of the wireless communication method 200, but these steps or operations are only examples, and the present application can also perform other operations or variations of the operations in FIG. 2.

[0063] In the embodiments of the present application, by designing the jump of the orthogonal sequences multiplied by part or all of the at least two SRS symbol groups, the randomization of the SRS is realized, so as to improve the receiving performance of the network side for the SRS, and to suppress the interference of the unknown terminal to the network side receiving the SRS.

[0064] In the embodiments of the present application, the length of one SRS symbol group is the same as the length of the orthogonal sequence corresponding thereto. For example, the length of the i th SRS symbol group in the at least two SRS symbol groups is the same as the length of the orthogonal sequence corresponding to the i th SRS symbol group.

[0065] The jump of the orthogonal sequence in the embodiments of the present application can be understood as that the orthogonal sequence before the jump is different from the orthogonal sequence after the jump. In the embodiments of the present application, optionally, the orthogonal sequence can jump over time.

[0066] The hopping of the orthogonal sequence in the embodiments of the present application can be equivalent to or replaced by the hopping of the index of the orthogonal sequence.

[0067] In some embodiments, the symbols of different SRS symbol groups in the at least two SRS symbol groups can be different symbols in one slot, or can be different symbols in different slots. Of course, the symbols of different SRS symbol groups can be different symbols in one slot and different symbols in different slots. The symbols in different slots can be symbols in different periods, or different SRS occupying symbols in one period.

[0068] In some embodiments, the types of the orthogonal sequence in the embodiments of the present application include but are not limited to at least one of the following:

[0069] Orthogonal cover code (OCC) code (or Walsh code), discrete Fourier transform (DFT) sequence.

[0070] In some embodiments, if the type of the orthogonal sequence in the embodiments of the present application is an OCC code (or Walsh code), the SRS symbol group in the embodiments of the present application applies a time domain OCC (TD-OCC) code.

[0071] For example, if the length of the OCC code is 2, the OCC group contains 2 OCC codes, and the index of the corresponding orthogonal sequence is ∈{0, 1}; wherein the OCC group can be as shown in Table 1.

[0072] Table 1

[0073] For example, if the length of the OCC code is 4, the OCC group contains 4 OCC codes, and the index of the corresponding orthogonal sequence is ∈{0, 1, 2, 3}; wherein the OCC group can be as shown in Table 2.

[0074] Table 2

[0075] For example, if the length of the OCC code is 8, the OCC group contains 8 OCC codes, and the index of the corresponding orthogonal sequence is ∈{0, 1, …, 7}; wherein the OCC group can be as shown in Table 3.

[0076] Table 3

[0077] For example, if the OCC code length is 16, the OCC group contains 16 OCC codes, and the index of the corresponding orthogonal sequence is ∈ {0, 1, …, 15}.

[0078] Further, the 2^M OCC codes of the OCC-2^N can be regarded as a matrix W, where 2^M is equal to the length of the OCC code, and the matrix corresponding to the 2^M OCC codes of the OCC-2^M is as follows:

[0079] Further, the OCC-2^M can be extended from the OCC-2, where 2^M is equal to the length of the OCC code, and the index of the corresponding orthogonal sequence is ∈ {0, 1, …, 2^M-1}.

[0080] In some embodiments, if the type of the orthogonal sequence described in the embodiments of the present application is a DFT type sequence, and if the length of the orthogonal sequence is N, then the orthogonal sequence group size is N (the orthogonal sequence group contains N orthogonal sequences), and the index of the corresponding orthogonal sequence is ∈ {0, 1, …, N-1}.

[0081] For example, a DFT type orthogonal sequence group contains the following orthogonal sequences:

[0082] [exp(j*2*pi / N*0*1),exp(j*2*pi / N*0*2),…,exp(j*2*pi / N*0*(N-1))]

[0083] [exp(j*2*pi / N*1*1),exp(j*2*pi / N*1*2),…,exp(j*2*pi / N*1*(N-1))]

[0084] [exp(j*2*pi / N*2*1),exp(j*2*pi / N*2*2),…,exp(j*2*pi / N*2*(N-1))]

[0085] …

[0086] [exp(j*2*pi / N*(N-1)*1),exp(j*2*pi / N*(N-1)*2),…,exp(j*2*pi / N*(N-1)*(N-1))]。

[0087] For example, another DFT type orthogonal sequence group contains the following orthogonal sequences, i.e., oversampled DFT sequences, O is the oversampling factor, and the orthogonal sequence group contains the following orthogonal sequences:

[0088] [exp(j*2*pi / (NO)*0*1),exp(j*2*pi / (NO)*0*2),…,exp(j*2*pi / (NO)*0*(N-1))]

[0089] [exp(j*2*pi / (NO)*O*1),exp(j*2*pi / (NO)*O*2),…,exp(j*2*pi / (NO)*O*(N-1))]

[0090] [exp(j*2*pi / (NO)*2O*1),exp(j*2*pi / (NO)*2O*2),…,exp(j*2*pi / (NO)*2O*(N-1))]

[0091] …

[0092] [exp(j*2*pi / (NO)*(N-1)O*1),exp(j*2*pi / (NO)*(N-1)O*2),…,exp(j*2*pi / (NO)*(N-1)O*(N-1))]。

[0093] In some embodiments, if the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups jump in one orthogonal sequence group, the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups can be part of the orthogonal sequences in the orthogonal sequence group.

[0094] In some embodiments, if the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups jump in one orthogonal sequence group, the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups are located in a specific orthogonal sequence set in the orthogonal sequence group.

[0095] It should be noted that the specific orthogonal sequence set described in the embodiments of the present application can be equivalent to or replaced by an orthogonal sequence restriction set, or similar names, which are not limited in the present application.

[0096] In some embodiments, the specific orthogonal sequence set is determined based on at least one of the following:

[0097] The bit in the bit sequence corresponding to the specific orthogonal sequence set in the orthogonal sequence group;

[0098] The first indication information is used to indicate the index of the orthogonal sequence in the specific orthogonal sequence set;

[0099] The second indication information is used to indicate that one orthogonal sequence set included in the orthogonal sequence group is the specific orthogonal sequence set.

[0100] In some embodiments, the wireless communication method 200 further comprises:

[0101] The terminal receives the first indication information and / or the second indication information from the network-side device.

[0102] For example, the network-side device configures a bitmap for the orthogonal sequence group, the bitmap has a length of the number of orthogonal sequences included in the orthogonal sequence group, one or more orthogonal sequences with a bit value of 1 in the bitmap are determined as the specific orthogonal sequence set, or one or more orthogonal sequences with a bit value of 0 in the bitmap are determined as the specific orthogonal sequence set.

[0103] Optionally, the orthogonal sequence group is divided into a plurality of orthogonal sequence sets, and the plurality of orthogonal sequence sets include the same or different number of orthogonal sequences.

[0104] In some embodiments, the specific orthogonal sequence set is determined based on the identifier of the terminal. For example, different identifiers of different terminals are associated with different orthogonal sequence sets.

[0105] In some embodiments, if the orthogonal sequences corresponding to part or all of the at least two SRS symbol groups jump in one orthogonal sequence group, the index of the orthogonal sequence corresponding to the first SRS symbol group in the at least two SRS symbol groups is determined based on at least one of the following:

[0106] An initial value of the index of the orthogonal sequence;

[0107] An offset value of the orthogonal sequence corresponding to the first SRS symbol group;

[0108] Time domain position information of the first SRS symbol group;

[0109] The number of orthogonal sequences included in the orthogonal sequence group;

[0110] At least one of the association relationship between the index of the orthogonal sequence and the SRS port index corresponding to the first SRS symbol group;

[0111] At least one of the association relationship between the index of the orthogonal sequence and the index of the SRS port group corresponding to the first SRS symbol group;

[0112] At least one of the association relationship between the TDM factor associated with the SRS port corresponding to the first SRS symbol group and the index of the SRS port;

[0113] a TDM factor associated with a SRS port group corresponding to the first SRS symbol group, and an association between the TDM factor and an index of the SRS port group;

[0114] a repetition factor, used to indicate R time units of repeated transmission, R being a positive integer.

[0115] It should be noted that the first SRS symbol group is any one of the at least two SRS symbol groups, and other SRS symbol groups in the at least two SRS symbol groups are similar to the first SRS symbol group, and can be referred to the first SRS symbol group, which will not be described here.

[0116] In some embodiments, the initial value of the index of the orthogonal sequence can be agreed by a protocol, or the initial value of the index of the orthogonal sequence can be configured by a network side device.

[0117] Optionally, the initial value of the index of the orthogonal sequence is [0~X-1]; wherein X is the size of the orthogonal sequence group, or X is the size of the specific orthogonal sequence set.

[0118] In an implementation manner, the index of the orthogonal sequence corresponding to the first SRS symbol group in the at least two SRS symbol groups is determined based on at least one of the following: a SRS port index corresponding to the first SRS symbol group, and an association between the index of the orthogonal sequence and the SRS port index. Specifically, if at least part of the at least two SRS ports are distinguished by the orthogonal sequence, the index of the orthogonal sequence is related to the SRS port index; otherwise, if the at least two SRS ports are not distinguished by the orthogonal sequence, the at least two SRS ports share the same orthogonal sequence, and the index of the orthogonal sequence is irrelevant to the SRS port index.

[0119] In the embodiment, the terminal can determine the index of the orthogonal sequence corresponding to each SRS symbol group in the at least two SRS symbol groups based on the SRS port index and perform hopping of the orthogonal sequence, so as to realize randomized sending of the SRS.

[0120] Optionally, the association between the index of the orthogonal sequence and the SRS port index can be agreed by a protocol, or the association between the index of the orthogonal sequence and the SRS port index can be configured by a network side device.

[0121] In an implementation, the index of the orthogonal sequence corresponding to the first SRS symbol group of the at least two SRS symbol groups is determined based on at least one of: an index of an SRS port group corresponding to the first SRS symbol group, and an association between the index of the orthogonal sequence and the index of the SRS port group. Specifically, if at least some of the at least two SRS port groups are distinguished by the orthogonal sequence, the index of the orthogonal sequence is associated with the index of the SRS port group; otherwise, if the at least two SRS port groups are not distinguished by the orthogonal sequence, the at least two SRS port groups share the same orthogonal sequence, and the index of the orthogonal sequence is not associated with the index of the SRS port group.

[0122] Optionally, the association between the index of the orthogonal sequence and the index of the SRS port group can be agreed by a protocol, or the association between the index of the orthogonal sequence and the index of the SRS port group can be configured by a network-side device.

[0123] In an implementation, the index of the orthogonal sequence corresponding to the first SRS symbol group of the at least two SRS symbol groups is determined based on at least one of: a time-division multiplexing (TDM) factor associated with an SRS port corresponding to the first SRS symbol group, and an association between the TDM factor and the index of the SRS port. Specifically, if at least some of the at least two SRS ports are distinguished by TDM, the index of the orthogonal sequence is associated with the TDM factor (a continuous symbol occupied by a TDM port); otherwise, if the at least two SRS ports are not distinguished by TDM, the index of the orthogonal sequence is not associated with the TDM factor (a continuous symbol occupied by a TDM port). The index of the orthogonal sequence is associated with the TDM factor, that is, different SRS ports distinguished by TDM share the same index of the orthogonal sequence.

[0124] In the embodiment, the terminal can determine the index of the orthogonal sequence corresponding to each of the at least two SRS symbol groups based on the TDM factor associated with the SRS port index and perform hopping of the orthogonal sequence, thereby realizing randomized transmission of the SRS.

[0125] Optionally, the association between the TDM factor and the index of the SRS port can be agreed by a protocol, or the association between the TDM factor and the index of the SRS port can be configured by a network-side device.

[0126] In an implementation, the index of the orthogonal sequence corresponding to the first SRS symbol group in the at least two SRS symbol groups is determined based on at least one of: a TDM factor associated with the SRS port group corresponding to the first SRS symbol group, and an association between the TDM factor and the index of the SRS port group. Specifically, if at least some of the at least two SRS port groups are distinguished by TDM, the index of the orthogonal sequence is related to the TDM factor (the consecutive symbols occupied by the TDM port); otherwise, if the at least two SRS port groups are not distinguished by TDM, the index of the orthogonal sequence is not related to the TDM factor (the consecutive symbols occupied by the TDM port). The index of the orthogonal sequence is related to the TDM factor, that is, different SRS port groups distinguished by TDM share the same index of the orthogonal sequence.

[0127] In the embodiment, the terminal can determine the index of the orthogonal sequence corresponding to each SRS symbol group in the at least two SRS symbol groups based on the TMD factor associated with the SRS port group index and perform hopping of the orthogonal sequence, thereby realizing randomized transmission of the SRS.

[0128] Optionally, the association between the TDM factor and the index of the SRS port group can be agreed by a protocol, or the association between the TDM factor and the index of the SRS port group can be configured by a network side device.

[0129] In some embodiments, if the hopping of the orthogonal sequence in the orthogonal sequence group occurs between the R time units and another R time unit, different SRS symbol groups in the R time units correspond to the same orthogonal sequence; and / or, if the hopping of the orthogonal sequence in the orthogonal sequence group occurs within the R time units, different SRS symbol groups in the R time units correspond to different orthogonal sequences, and the hopping manner of the orthogonal sequence in different R time units is the same. Optionally, the time unit in the embodiments of the present application includes but is not limited to one of the following: frame, subframe, time slot, symbol, hour, minute, second, millisecond, microsecond.

[0130] For example, each R time unit is also called a time unit corresponding to a frequency hopping counter (SRS transmission counter). Therefore, the hopping of the orthogonal sequence is associated with the SRS frequency hopping counter.

[0131] In an implementation, an index of a corresponding orthogonal sequence of a first SRS symbol group in the at least two SRS symbol groups is determined based on a repetition factor:

[0132] If a hopping of the orthogonal sequences in the set of orthogonal sequences occurs between the R time units and another R time units, different SRS symbol groups within the R time units correspond to a same orthogonal sequence; and / or, if a hopping of the orthogonal sequences in the set of orthogonal sequences occurs within the R time units, different SRS symbol groups within the R time units correspond to different orthogonal sequences, and a hopping manner of the orthogonal sequences in different R time units is same.

[0133] In the embodiment, the terminal can determine an index of a corresponding orthogonal sequence of each SRS symbol group in the at least two SRS symbol groups based on a repetition factor and perform a hopping of the orthogonal sequences, thereby realizing a randomized sending of the SRS.

[0134] For example, if the network side configures a repetition factor, or the network side configures a repetition factor and indicates that the index of the orthogonal sequence is related to the repetition factor, the index of the orthogonal sequence is related to the repetition factor. That is, the index of the orthogonal sequence can be determined based on the repetition factor. For example, repetition factor = R, indicating R symbols of repeated transmission, or indicating a symbol occupied by a frequency hopping once.

[0135] For example, if the network side configures a hopping of the orthogonal sequences, or the network configures a hopping of the orthogonal sequences and indicates that the index of the orthogonal sequence is related to the repetition factor, the index of the orthogonal sequence is related to the repetition factor. For example, repetition factor = R, indicating R symbols of repeated transmission, or indicating a symbol occupied by a frequency hopping once.

[0136] In some embodiments, the index of the corresponding orthogonal sequence of the first SRS symbol group is equal to an initial value of the index of the orthogonal sequence plus or plus modulo an orthogonal sequence offset value corresponding to the first SRS symbol group; wherein a modulus is a size of the set of orthogonal sequences, or a size of a specific set of orthogonal sequences.

[0137] In some embodiments, the index of the orthogonal sequence corresponding to the first SRS symbol group is determined based on the following Formula 1:

[0138] wherein, in Formula 1, n index represents the index of the orthogonal sequence corresponding to the first SRS symbol group, represents an initial value of the index of the orthogonal sequence, represents an orthogonal sequence offset value corresponding to the first SRS symbol group.

[0139] It should be noted that the first SRS symbol group is any one of the at least two SRS symbol groups, and the above Formula 1 is described only by taking the first SRS symbol group as an example. The other SRS symbol groups in the at least two SRS symbol groups are similar to the first SRS symbol group, and the index of the corresponding orthogonal sequence can be determined by referring to the first SRS symbol group. For the sake of brevity, it will not be described here.

[0140] Optionally, in the above Formula 1, if is 0 or does not exist,

[0141] For example, the SRS symbols in a slot can be as shown in FIG. 3. The SRS symbols are divided into three SRS symbol groups, namely SRS symbol group 1, SRS symbol group 2 and SRS symbol group 3. Orthogonal sequence hopping is performed between each SRS symbol group. Each SRS symbol group includes 4 SRS symbols, and the length of each orthogonal sequence is 4. Among them, the orthogonal sequence corresponding to the SRS symbol group 1 is TD-OCC index x, the orthogonal sequence corresponding to the SRS symbol group 2 is TD-OCC index y, and the orthogonal sequence corresponding to the SRS symbol group 3 is TD-OCC index z. For example, the first SRS is obtained by multiplying the SRS symbol group 1 by the TD-OCC index x, multiplying the SRS symbol group 2 by the TD-OCC index y, and multiplying the SRS symbol group 3 by the TD-OCC index z.

Exemplarily, the pseudo-random sequence c(n) with a length of MPN, where n = 0, 1,..., M PN -1, is defined by: c(n) = (x1(n+N C )+x2(n+N C ))mod2 x1(n+31) = (x1(n+3)+x1(n))mod2 x2(n+31) = (x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2

[0163] where N C = 1600, and the first m sequence x1(n) is initialized based on x1(0) = 1, x1(n) = 0, n = 1, 2,..., 30; the initialization of the second m sequence x2(n) is determined by , the value of which is the 'initialization seed'.

[0164] Optionally, the initialization seed can be agreed by a protocol, or the initialization seed can be configured by a network side.

Other SRS symbol groups in the at least two SRS symbol groups are similar to the first SRS symbol group, and the corresponding orthogonal sequence offset value can be determined by referring to the first SRS symbol group. For the sake of brevity, it will not be described here again.

[0167] In some embodiments, the index of the orthogonal sequence corresponding to each SRS symbol group is related to the SRS port index. That is, at least part of the SRS ports are distinguished by the orthogonal sequence. Specifically, the following mode 1, mode 2 and mode 3 are included.

[0169] Optionally, since at least part of the SRS ports are distinguished by the orthogonal sequence, the SRS ports can be further grouped, and the SRS ports in the same group correspond to the same index of the orthogonal sequence. Therefore, the different SRS ports described above can also be expressed as different SRS port groups.

Specifically, the index of the orthogonal sequence can be determined by the following method 4 or method 5.

[0210] Further, if R>X, R symbol is divided into R / X SRS symbol groups, and the orthogonal sequence jumps between the R / X SRS symbol groups.

[0211] In some embodiments, the orthogonal sequence offset value corresponding to each SRS symbol group is related to the TDM factor, or the orthogonal sequence offset value corresponding to each SRS symbol group is related to frequency hopping. When the TDM port is configured, multiple ports of SRS can occupy different symbols. Here, assuming that the TDM factor is s, multiple ports of SRS can occupy different s symbols. If repetition is considered, each port occupies R symbol, and multiple ports of SRS can occupy different sR symbols.

[0221] mod represents a modulo operation.

[0222] Further, although the multiple groups of ports of SRS occupy different symbols, the orthogonal sequence hopping associated with the multiple groups of ports is consistent.

[0223] For example, as shown in FIG. 4, the network side configures a set of orthogonal sequences as TD-OCC2; the size of the set of orthogonal sequences is 2, and the set of orthogonal sequences contains 2 orthogonal sequences. The network side configures 1 slot to contain 12 symbols, the number of ports is 8, and some ports are distinguished by TDM (i.e., ports 0, 1, 4, and 5 are distinguished from ports 2, 3, 6, and 7 by TDM), corresponding to s = 2. Although ports 0, 1, 4, and 5 occupy different symbols from ports 2, 3, 6, and 7, the orthogonal sequence hopping associated with the two ports is consistent. As shown in FIG. 4, hopping is performed in units of 4 symbols. Among the 4 symbols, each of the 2 symbols contains ports 0, 1, 4, and 5 and ports 2, 3, 6, and 7. The 2 symbols of ports 0, 1, 4, and 5 are multiplied by the TD-OCC2 sequence, and the 2 symbols of ports 2, 3, 6, and 7 are multiplied by the TD-OCC2 sequence, and the TD-OCC2 sequences of the two are the same.

In addition, in the embodiments of the present application, the first SRS symbol group and the second SRS symbol group can be the same or different, which is not limited in the present application.

[0237] In some embodiments, the indexes of the orthogonal sequences multiplied by the SRS symbol groups in different orthogonal sequence groups are the same; or the indexes of the orthogonal sequences multiplied by the SRS symbol groups in different orthogonal sequence groups are different.

Optionally, the specific rule is agreed by a protocol, or the specific rule is configured by a network side device.

[0241] In some embodiments, if the indexes of the orthogonal sequences multiplied by the SRS symbol groups in different orthogonal sequence groups are different, the orthogonal sequences can be selected from the orthogonal sequence groups based on the above formulas 1 to 8.

[0246] In this embodiment, the terminal can perform orthogonal sequence hopping based on the indication of the network side device, thereby realizing randomized sending of SRS.

[0247] It should be noted that in this embodiment, whether to perform 'orthogonal sequence hopping' can be indicated by the network side device; if the network side device does not indicate or indicates that the orthogonal sequence does not hop, the same orthogonal sequence is multiplied.

[0248] In some embodiments, before the terminal sends the first SRS to the network side device, the wireless communication method 200 further includes:

[0249] The terminal receives second information from the network side device;

[0251] In the first hopping mode, the orthogonal sequences corresponding to part or all of the SRS symbol groups in the at least two SRS symbol groups hop in one orthogonal sequence group.

[0252] In the second hopping mode, the orthogonal sequences corresponding to part or all of the SRS symbol groups in the at least two SRS symbol groups hop in different orthogonal sequence groups.

[0253] In this embodiment, the terminal can determine the hopping mode of the orthogonal sequence based on the indication of the network side device and perform orthogonal sequence hopping based on the determined orthogonal sequence hopping mode, thereby realizing randomized sending of SRS.

[0254] In some embodiments, at least part of the SRS symbol groups in the at least two SRS symbol groups include different numbers of SRS symbols, and / or the lengths of the orthogonal sequences or orthogonal sequence groups corresponding to at least part of the SRS symbol groups in the at least two SRS symbol groups are different.

[0255] For example, in a slot, a plurality of SRS symbols (e.g., the number of SRS symbols is 10 or the SRS repetition factor = 10) are divided into different SRS symbol groups. As shown in FIG. 5, the plurality of SRS symbols are divided into three SRS symbol groups, denoted as SRS symbol group 1, SRS symbol group 2, and SRS symbol group 3. The SRS symbol group 1 contains 4 symbols, the SRS symbol group 2 contains 4 symbols, and the SRS symbol group 3 contains 2 symbols. Specifically, for the SRS symbol group 1 and the SRS symbol group 2, the corresponding TD-OCC indexes can jump in the orthogonal sequence group of TD-OCC 4; and for the SRS symbol group 3, the corresponding TD-OCC indexes can jump in the orthogonal sequence group of TD-OCC 2.

Specifically, by designing the orthogonal sequences that multiply part or all of the at least two SRS symbol groups to jump, the randomization transmission of the SRS is realized, so as to improve the receiving performance of the network side for the SRS and suppress the interference of the unknown terminal to the network side receiving the SRS.
