METHOD OF COMMUNICATION AND COMMUNICATION DEVICE TECHNICAL FIELD

[0001] This application relates to the field of communication and, more specifically, to a method of communication and a communication device in the field of communication. BACKGROUND

[0002] A sounding reference signal (SRS) is an uplink reference signal sent by a terminal device to a network device (e.g., a base station). The network device can perform channel estimation on an uplink (UL) channel based on the SRS, or the network device can perform channel estimation on a downlink (DL) channel based on channel reciprocity, so that the network device can perform uplink or downlink transmission with the terminal device.

[0003] To avoid interference that occurs when different terminal devices send SRSs, the SRS sequences used by different terminal devices can be cyclic shift (CS) values ​​from different base sequences, or they can be different CS values ​​from the same base sequence. For different base sequences, interference occurs between the resulting SRS sequences, regardless of whether the same cyclic shift value or different cyclic shift values ​​are used. Different CSs from the same base sequence form different SRS sequences, and a difference between two different CS values ​​causes interference between different SRS sequences from the same base sequence. Consequently, the performance of sending an SRS is affected. SUMMARY

A port group corresponds to a set of comb offsets that supports hops. One or more port groups correspond to a total of one or more sets of comb offsets.

[0006] In the previous solution, Cos, which support hopping, of ports in different port groups can be different. This can reduce the probability of repetition with a Co occupied by a UE port that does not support Co hopping, reducing interference during SRS transmission.

Different groups of ports can correspond to different sets of comb offsets. In this way, ports in different groups of ports can jump at different CO steps. This can reduce the probability of Petition 870250101444, dated 05 / 11 / 2025, page 9 / 254 3 / 230 repeat with a CO from an EU port that does not support CO hopping, to reduce interference during SRS transmission and improve SRS transmission performance.

[00230] Figure 1 is a diagram of a communication system to which the embodiments of this application apply. As shown in Figure 1, the wireless communication system may include a network device 110 and one or more terminal devices (for example, a terminal device 121 and a terminal device 122 shown in Figure 1) that communicate with each other. When network device 110 sends a signal, network device 110 is a transmitting end, and terminal device 121 or terminal device 122 is a receiving end. Conversely, when terminal device 121 or terminal device 122 sends a signal, the Petition 870250101444, dated 05 / 11 / 2025, page 82 / 254 76 / 230 terminal device 121 or terminal device 122 is a transmitting end, and network device 110 is a receiving end.

[00231] Network device 110 may be an access network device configured to communicate with terminal device 121 or terminal device 122. The access network device may be a base transceiver station (BTS) in a GSM system or a CDMA system; It can be a base station, that is, a NodeB (NodeB, NB), in a WCDMA system; or it can be an evolved base station, that is, an evolved NodeB (eNB or eNodeB), in a system LTE; or it could be a radio controller in a cloud radio access network (CRAN) scenario; Or it could be a next-generation NodeB (gNodeB, gNB) in a fifth-generation mobile communication technology (5G), i.e., new radio access (NR), or a base station in another future network system. Alternatively, the 110 network device could be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, a network device in a future evolved PLMN network, or similar. This is not limited to the embodiments of this application.

[00232] The terminal device 121 or the terminal device 122 may be user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user appliance. The terminal device may alternatively be a terminal in the form of a mobile phone, a cordless phone, a session initiation protocol (SIP) phone, a Petition 870250101444, dated 05 / 11 / 2025, page 83 / 254 77 / 230 wireless local loop station (WLL), a personal digital assistant (PDA), a portable device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a portable device, a wearable device, a computing device, a portable device, a vehicle-mounted device or similar, a smartphone, smart glasses, a terminal device on a 5G network, a terminal device on a future public terrestrial mobile network (PLMN) or similar. This is not limited to the embodiments of this application.

[00233] It can be understood that network device 110 in Figure 1 can alternatively be replaced by a terminal device 110. More specifically, the modalities of this request are applied to a direct communication scenario, for example, device-to-device (D2D). For example, the modalities of this request can be applied to vehicle-to-everything (V2X) devices.

[00234] For ease of description, device numbers are omitted in the following modalities. For example, a terminal device represents terminal device 121 or terminal device 122, and a network device represents network device 110.

[00235] First, some concepts are described in the modalities of this request. 1. SRS, SRS resource, SRS port and SRS comb

[00236] An SRS is an uplink reference signal sent by an end device to a network device (e.g., a base station). The access network device obtains a UL channel from the end device based on the SRS sent by the end device. Alternatively, the access network device obtains a DL channel from the end device based on channel reciprocity, to perform Petition 870250101444, dated 05 / 11 / 2025, page 84 / 254 78 / 230 data scheduling (e.g., pre-coding corresponding to downlink data, a modulation and coding scheme (MCS) corresponding to downlink data, or a scheduled time-frequency resource corresponding to downlink data) on the terminal device based on the DL channel. User equipment (UE) and / or a user in the following descriptions may be considered terminal devices.

[00237] An SRS resource is configured by a network device (e.g., a base station), and an SRS resource can correspond to a time-frequency resource and a code domain resource. A code domain resource corresponds to an SRS sequence and is also called an SRS sequence resource. An SRS resource can correspond to one or more SRS ports. One or more SRS ports can correspond to the same time-frequency resource, and different SRS ports correspond to different SRS sequences, or different SRS ports correspond to different time-frequency resources. In one implementation, the SRS resource is configured semi-statically by the network device using a higher-layer parameter. An SRS port corresponds to a group of time-frequency resources and an SRS sequence.A terminal device sends a corresponding SRS sequence on a time-frequency resource corresponding to one or more ports that correspond to an SRS resource. The SRS sequence may also be called an SRS transmission symbol sequence, SRS transmission symbol vector, or similar. The naming of an SRS sequence is not limited in the modalities of this application.

[00238] SRS Port: An SRS port is also called an antenna port or port. In the following embodiments, a port represents an SRS port. The SRS port is used to port Petition 870250101444, dated 05 / 11 / 2025, p. 85 / 254 79 / 230 an SRS. An SRS gate corresponds to an SRS, or an SRS gate corresponds to an SRS sequence. Different SRS gates can be multiplexed in at least one of the following modes: code division mode, frequency division mode, time division mode, or space division mode. In a . , , , . , . NR and {1,2,4} implementation, an SRS feature can include ap r' gates , _.....{n}Np -1P = 1000 + i „ , . of SRS (antenna port)u'l0'=0, where . Each port of SRS corresponds to at least one of the following resources: a specific time-domain resource, a frequency-domain resource, or a code-domain resource. Typically, each SRS port occupies different time-domain, frequency-domain, or code-domain resources to reduce mutual interference or ensure orthogonality between ports. Each SRS port corresponds to a physical antenna or a virtual antenna of a terminal device. In some embodiments of this application, a port index of 0 is equivalent to a port index of 1000, a port index of 1 is equivalent to a port index of 1001, a port index of 2 is equivalent to a port index of 1002 and a port index 3 is equivalent to a port index 1003, where port index 1, port index 2, port index 3, and port index 4 represent the port index. 1001, port index 1002, port index 1003, and port index 1004, respectively. To simplify the description, in an example process in this application, a port 0 can represent port index 0, a port 1 can represent port index 1, a port 2 can represent port index 2, and a port 3 can represent port index 3. The number of ports is not limited to 4, and the number of ports can be greater than 4. For example, there are eight ports, which correspond to port indices 0 to 7 or indices 1000 to 1007, respectively.

[00240] SRS Comb: A comb divides frequency-domain subcarriers into a plurality of groups, and the frequency-domain gap between two adjacent subcarriers in each subcarrier group is a fixed value. That is, the frequency-domain subcarriers in an SRS comb are distributed at equal intervals. The frequency-domain gap between two subcarriers is also called ..... ... K_ , for total number of combs TC. The comb also contains some subcarriers extracted at equal intervals in the frequency domain. An extraction interval is called the quantity of ... K^ K^ . ... The total comb count (TC) is semi-statically configured by a network device using a higher-layer parameter. For example, KTC {2,4,8}. The total comb count KTC can also be understood as the frequency-domain subcarriers divided into equally spaced TC subcarrier groups. The total comb count can also be called comb density or frequency-domain comb count. The total comb count can also represent a total number of supported comb offsets. Figure 2 shows an example of a comb in the case of three different comb counts, according to this request. A comb can be understood as a group of subcarriers corresponding to a comb offset. The comb offset can also be called a comb, for short. For example, a comb offset X can also be called comb X.In Figure 2, each cell represents a resource element (resource element, RE) or a subcarrier, and a cell. Petition 870250101444, dated 05 / 11 / 2025, p. 87 / 254 81 / 230 filled in black is an example of an RE position or subcarrier position occupied by a comb in the case of ..... . , , _. „ K= =2 different comb quantities. On the left of Figure 2, TC indicates that the subcarriers in the frequency domain are divided, based on a subcarrier spacing of 2, into two groups of subcarriers, namely, two combs, which correspond respectively to comb offsets 0 and 1. An SRS port of a terminal device can send a corresponding SRS on one of the two combs. In the middle of Figure 2, KT== 4 indicates that the frequency domain subcarriers are divided, based on a subcarrier spacing of 4, into four subcarrier groups, namely four combs, which correspond respectively to comb offsets 0, 1, 2, and 3. An SRS port of a terminal device can send a corresponding SRS on one of the four combs. (To the right of the Figure) 2, KTC 8 indicates that the frequency domain subcarriers are divided, based on a subcarrier spacing of 8, into eight subcarrier groups, namely eight combs, which correspond respectively to comb offsets 0, 1, 2, 3, 4, 5, 6, and 7. An SRS port of a terminal device can send an SRS on one of the eight combs. A comb offset (CO) indicates a subcarrier offset value of a comb relative to a reference comb. For example, a comb offset of a black-filled cell in Figure 2 is 0. A plurality of ports of an SRS resource can be distributed on the same comb or on two or more combs. The reference comb can be an initial subcarrier of a frequency domain unit, where the frequency domain unit can be one or more RBs, or a frequency domain sub-band.In one implementation, a reference comb offset corresponding to a subcarrier 0 that corresponds to a common resource block 0 can be defined as 0. In another... Petition 870250101444, dated 05 / 11 / 2025, p. 88 / 254 In the 82 / 230 implementation, a reference comb offset corresponding to a lower subcarrier in a bandwidth part (BWP) can be defined as 0. A comb offset corresponding to the reference comb is called the reference comb offset. Typically, the reference comb offset is 0.

[00241] For example, a CO of a gatep can be denoted as kpkpTC, and an initial frequency domain position0 of the gatep can be obtained according to formula (1): kp= kp+nFH k0k0 + «Offset + nRPFS+ nOffset (1)

H9transmissionComb. is a maximum cyclic displacement value. H9 One meaning of ® can be understood as equally dividing the delay domain into ® portions, or it can be understood as equally dividing a phase value into 2 item portions. When CS values ​​are allocated to a plurality of ports corresponding to an SRS feature, CSs corresponding to the ports of the SRS feature are equally divided within a cs,max length of ® based on a maximum range, if possible, to ensure minimal interference between the plurality of ports. Petition 870250101444, dated 05 / 11 / 2025, page 92 / 254 86 / 230 of the SRS resource. In one implementation, it is a relationship of nc, max K association between RS and TC values, as shown in Table 1. Table 1 KTC cs ,max nRS 2 8 4 12 8 6

[00251] For different base sequences, interference occurs between the obtained SRS sequences, regardless of whether the same cyclic offset value or different cyclic offset values ​​are used. More specifically, the network device allocates, to different terminal devices, SRS sequences obtained based on the same cyclic offset value or on different cyclic offset values ​​from different base sequences. The terminal devices can send the SRS sequences on the same time-frequency resource, and the SRS sequences cause interference between the terminal devices.

[00252] For the same base sequence, different SRS sequences can be obtained using different cyclic offset values ​​α. Since the SRS sequences obtained based on the same base sequence and different cyclic offset values ​​are orthogonal to each other, the network device can allocate the SRS sequences obtained based on the same base sequence and different cyclic offset values ​​to different terminal devices, and the terminal devices can send the SRS sequences on the same time frequency resource. The SRS sequences do not cause interference between terminal devices. However, since the distances from different terminal devices to different network devices are different, different terminal devices have Petition 870250101444, dated 05 / 11 / 2025, page 93 / 254 87 / 230 different delays. A transmission reception point (TRP) 1 and a TRP 2 are used as an example. As shown in Figure 3, TRP 1 and TRP 2 configure mutually orthogonal SRS features for UE 1 and UE 2. Typically, the base sequence of an SRS 1 is the same as the base sequence of an SRS 2, but the cyclic offset values ​​α of SRS 1 and SRS 2 are different. Thus, SRS 1 and SRS 2 are orthogonal to each other. However, since the distances from UE1 and UE2 to TRP1 and TRP2 are different, the delay of SRS1 sent by UE1 to TRP2 is different from the propagation delay of SRS2 sent by UE2 to TRP2. For example, as shown in Figure 3, a propagation delay from UE1 to TRP1 is ^1,1, a propagation delay from UE1 to TRP2 is T1,2, a propagation delay from UE2 to TRP1 is ^2,1, and a propagation delay from UE2 to TRP2 is ^2,2. Therefore, ^1,1 <^1,2, and ^2,1 ^2,2.Orthogonality is guaranteed through code-division multiplexing. For example, orthogonality between SRS 1 and SRS 2 is guaranteed by using different cyclic offset values ​​for the SRS. Assuming the maximum number of SRS CSs configured for UE 1 and UE 2 is 12, SRS 1 occupies CS 0, CS 3, CS 6, and CS 9, and SRS 2 occupies CS 1, CS 4, CS 7, and CS 10. When there is no delay difference, SRS 1 and SRS 2 occupy different delay domain ranges, so code-division orthogonality can be guaranteed. However, when it is a delay difference, the propagation delay between TRP 2 and UE 1 is greater than the propagation delay between TRP 2 and UE 2. It is assumed that TRP 2 and UE 2 are temporally aligned. In this case, a channel result obtained by TRP 2 measuring SRS 1 has a shift in the delay domain, leading to interference with SRS 2 and affecting the... Petition 870250101444, dated 05 / 11 / 2025, page 94 / 254 88 / 230 channel measurement accuracy.

[00253] In a possible implementation, to solve the interference problem above, a frequency domain resource for sending an SRS can be randomized by means of comb shift hopping (CO hopping), to reduce interference in the SRS. A good interference randomization effect can be achieved by randomizing, by means of CO hopping, a frequency domain resource for sending an SRS. However, in a real application scenario, there is a terminal device that supports CO hopping and a terminal device that does not support CO hopping. The terminal device that does not support CO hopping can also be called a legacy terminal device (e.g., legacy UE or a terminal device from version 15 to version 17). In this application, the terminal device that supports CO hopping is a terminal device that can randomize, by means of CO hopping, a frequency domain resource for sending an SRS.In other words, a terminal device that supports CO hopping has the capability or function to randomize, via CO hopping, a frequency domain resource to send an SRS. Conversely, a terminal device that does not support CO hopping is a terminal device that cannot randomize, via CO hopping, a frequency domain resource to send an SRS. In other words, a terminal device that does not support CO hopping does not have the capability or function to randomize, via CO hopping, a frequency domain resource to send an SRS. When CO hopping is enabled, to avoid a more serious interference problem caused by random hopping, a plurality of ports corresponding to an SRS resource must occupy the same CO.When a network device configures, on the same multiplexing module, one port corresponding to an SRS resource of the terminal device that supports CO hopping and one port corresponding to an SRS resource of the terminal device that... Petition 870250101444, dated 05 / 11 / 2025, page 95 / 254 Since 89 / 230 does not support CO hopping, the channel estimation performance of the two terminal devices can be seriously degraded. Therefore, how to avoid the degradation of channel estimation performance in the previous case, by making the most of the interference randomization effect of CO hopping, is an urgent problem to be solved. The comb offsets for hopping a plurality of ports corresponding to an SRS feature of a terminal device are consistent. For example, in CO hopping, the COs of the ports can change randomly. For example, as shown in Figure 4, an SRS feature corresponds to a port 0, a port 1, a port 2, and a port 3; the comb offsets of port 0 and port 2 are a CO 0, and the comb offsets of port 1 and port 3 are a CO 2. In CO hopping, all four ports can be moved down by one CO.After the movement, the comb offsets of port 0 and port 2 are a CO 1, and the comb offsets of port 1 and port 3 are a CO 3. However, CO 3 was occupied by a CO that does not support CO hopping. Consequently, severe interference is caused to an SRS sent on CO 3.

[00254] That is, in the previous implementation, to reduce interference, the COs by which the ports used by the terminal device to send an SRS are hopped are the same. Consequently, a CO obtained by hopping overlaps with a UE CO that does not support hopping, and sending an SRS on the overlapping CO is affected. In embodiments of this application, a plurality of ports for sending an SRS can be grouped, and different port groups can correspond to different CO hopping sets. In this way, ports in different port groups can hop at different CO steps. This can reduce the probability of repetition with a CO from a UE port that does not support CO hopping, to reduce interference during SRS transmission.

[00255] The following describes a method of communication in Petition 870250101444, dated 05 / 11 / 2025, page 96 / 254 90 / 230 modalities of this request with reference to Figure 5. As shown in Figure 5, communication method 500 includes the following steps.

[00256] S510: A terminal device sends an SRS based on at least one comb offset in a first set of comb offsets ^p corresponding to a pth group of ports, and a network device receives the SRS based on at least one comb offset in the first set of comb offsets ^p corresponding to the pth group of ports. NR

[00257] A first feature of SRS corresponds to the gates. The SRS gates can be divided into P groups of gates. The P groups of gates include the op group of gates. A value of P is a positive integer greater than or equal to 1 and less than or equal to nsrs ap. P is a positive integer ranging from 1 to P. For example, p can be sequentially 1, 2,... and P; or p can be a positive integer ranging from 0 to P-1, and p can NSRS can be sequentially 0, 1,... and P-1. Optionally, ap can be configured by the network device for the terminal device.

[00258] Optionally, the first set of comb offsets ^p can also be named as a set that supports CO hopping, or it can be named as a CO value to which the op-th group of ports can be mapped after CO hopping is enabled. The first set of comb offsets ^p can alternatively be replaced by a first comb offset range ^p, or it can be replaced by a first comb offset area ^p, or similar. The name of the first set of comb offsets is not Petition 870250101444, dated 05 / 11 / 2025, p. 97 / 254 91 / 230 limited in this modality of this request. n,

[00259] Optionally, a length p of the first set of comb offsets φ can be specified in a protocol or configured by the network device. The length p of the first set of comb offsets φ can also be understood as a quantity of comb offsets included in the first set of comb offsets ^p. n is a positive integer greater than or equal to 1 and less than or equal to K^n. aTC.p=1 indicates that the pth group of ports does not support CO hopping, or at each SRS transmission, an SRS corresponding to the pth group of ports can only be sent in a single n_K^...n.

NSRS [0 02 60] Optionally, P being 1 indicates that the ports corresponding to the first SRS feature belong to an NSSRS group of ports, where a is a positive integer; indicates that NSRSasappotas corresponding to the first SRS feature correspond to the same first set of comb displacements φ; or NSRS indicates that the ports corresponding to the first SRS resource correspond to the same available CO value for which mapping can be performed (when CO hopping is enabled). srs SfSRS

[00261] Optionally,Psendoap indicates that one of theap Petition 870250101444, dated 05 / 11 / 2025, p. 98 / 254 92 / 230 ports corresponding to the first SRS feature belong to a group of ports; to be more specific, the length of the first set of comb offsets ^p is 1, and a port in the pth group of ports corresponds to a comb offset; and indicates that each port of the first SRS feature corresponds to a first set of comb offsets ^p. In one implementation, all ports of the first SRS feature can correspond to different first sets of comb offsets ^p. In that case, all ports of the first SRS feature can perform CO hops in different available CO areas.

[00262] Optionally, P being a positive integer greater than or less than 1 indicates that at least two gates belong to a gate group. In one implementation, different gate groups of the first SRS feature's P gate groups correspond to different sets of offsets of the first comb ^p, and different gate groups include different gates. In this case, the gates included in the different gate groups of the first SRS feature can perform CO hops in different available CO areas.

[00263] Optionally, prior to S510, the terminal device can NSRS p group the ports and obtain the port groups based on the NSRS quantity of port groups and the ports. Optionally, prior to S510, the network device can NSRS p configure the ports and the quantity of port groups for the terminal device. The terminal device can NSRS determine the port groups based on the ports and that are configured by the network device. For example, the Petition 870250101444, dated 05 / 11 / 2025, p. 99 / 254 93 / 230 is the number of doors included in each door group. NSRSap NSRS / P If 'seapnão é um número inteiro', an operation of NSRS / P rounding up or down can be performed to obtain the number of ports included in each port group. Optionally, each port group can be obtained by NSR by means of equally spaced extraction of the ports. To be more specific, the interval between the port indices of adjacent NSRS / p ports included in each of the port groups is . For example, when the port indices corresponding to a plurality of ports included in each port group are sorted in ascending order, the absolute value of a , „ NR / p difference between the port indices of adjacent ports isap Since the CSs corresponding to the ports of an SRS resource are η^max divided equally within an RS length based on a maximum interval, if possible, during port grouping, extraction is also performed at equal intervals as far as possible. In this way, when at least one set of comb offsets is selected from the first set of comb offsets for a port group, the probability of overlap with a comb offset of a port of an SRS resource from another terminal device can be minimized to help reduce interference. For example, NSRS is 4, and there are a total of four ports: port 0, port 1, port 2, and port 3. The ports can be divided into two port groups. A first port group includes port 0 and port 2, and a second port group includes port 1 and port 3.For the first group of gates, the difference between the gate indices corresponding to gate 2 and gate 0 is 2. For the second group of gates, the difference between... Petition 870250101444, dated 05 / 11 / 2025, pp. 100 / 254 94 / 230 the port indexes corresponding to port 3 and port 1 is also 2.

[00264] Optionally, before S510, or before the terminal NSRS device groups the ports, method 500 also includes: The terminal device determines the execution of the CO hop and, upon executing the CO hop, the terminal device can perform NSRS. S510 or group asapportas. In other words, when determining that the SRS needs to be sent in hop mode, the terminal NSRS device can perform S510 or group asapportas. Optionally, the network device can send indication information to indicate to the terminal device to perform the CO hop, and the terminal device can determine, based on the indication information to indicate to the terminal device to perform the CO hop, the performance of the CO hop. Optionally, the terminal device can determine, with n„. Based on the length of the first set of comb displacements ^p, the CO jump should be performed. For example, if the length np of the first set of comb displacements^ is 1, it indicates that the CO jump should not be performed, and if the length np of the first set of comb displacements^ is greater than 1 and less than or equal to TCTC, it indicates that the jump should be performed. CO2 must be performed. One way to determine, by the terminal device, whether the CO2 jump has taken place is not limited in this embodiment of this request.

[00265] Optionally, the terminal device can determine a set of comb offsets for each of the port groups. For example, the network device can directly configure the set of comb offsets for each port group; or the set of comb offsets for each Petition 870250101444, dated 05 / 11 / 2025, page 101 / 254 The 95 / 230 port group can be specified in the protocol; or the network device can configure a parameter to determine the set of comb offsets for each port group, and the terminal device determines the set of comb offsets for each port group based on the configured parameter. One way for the terminal device to determine the set of comb offsets for each of the P port groups is not limited in this embodiment of this application. Optionally, in some possible implementations, the network device can configure, for the terminal device, a set of comb offsets that corresponds to each port group and that does not support CO hopping, and the terminal device determines, based on the TC comb offsets and the set of comb offsets that does not support CO hopping, a set of comb offsets that supports CO hopping for each port group.The sum of a number of comb offsets included in a set of comb offsets that does not support CO hopping, from a gate group, and a number of comb offsets included in a set of comb offsets that does support CO hopping, from the gate group is KTC included in supports hopping. A set of comb offsets is a set of comb offsets, other than CO, from a gate group, and comb offsets included in a set of comb offsets that supports CO hopping from the gate group is a set that supports hopping called a jump set, used for example, the A set of comb offsets, of CO, of a group of ports also a set of offsets to send a corresponding SRS. The fifth group of ports is used which cannot be a comb that cannot be to the group of ports. as an example.KTC For and a second set of comb displacements, which does not support Petition 870250101444, dated 05 / 11 / 2025, p. 102 / 254 96 / 230 CO jump, the th gate group is {θΊ'2,3}. In this case, the first set of comb shifts that supports CO jump, the th gate group is as follows: ^p{4,5,6,7} The sum of the length of the first set of comb displacements and the length of the second set of comb displacements is A union set that includes the first set of comb displacements and the second set of comb displacements is {0,1,2,3,4,5,6,7}.

[00266] The set of comb offsets, determined by the terminal device, of each gate group can take different forms. The first set of comb offsets ψp of the ¼ gate group of the P gate groups is used below as an example for description. The following describes, in three cases, the first set of comb offsets ψp corresponding to the ¼ gate group.

[00267] Case 1: In one possible implementation, the comb offset intervals between any two adjacent comb offsets in the first set of comb offsets ψp corresponding to the opth gate group are equal. In other words, the comb offsets included in the first set of comb offsets ψp are discrete at equal intervals. Two adjacent comb offsets can be understood as follows: The comb offset values ​​included in the first set of comb offsets ψp are sorted in ascending order to obtain the following set: ψ = {CO°p, COp ,-,CO^..„COnf} where a k-th comb displacement cop co^ -1 is adjacent to a k-1st comb displacement p. That the comb displacement intervals between any two Petition 870250101444, dated 05 / 11 / 2025, p. 103 / 254 The statement that 97 / 230 adjacent comb displacements are equal can be understood as follows: A difference between the 97th comb displacement and the 97th displacement of adjacent combs is equal. ok ^simo displacement The one with the comb CO^ - CO-1 is a difference between a j-th comb displacement.

For example, TC is 8, and the first set of comb displacements is as follows: mp = {0,2,4,6} This indicates that the eighth group of gates corresponds to a comb offset 0, a comb offset 2, a comb offset 4, and a comb offset 6, and a comb offset interval between two adjacent comb offsets is 2, wherein a interval between comb offset 6 and comb offset 0 can also be 2.

[00268] It should be noted that the above describes a definition of two adjacent comb offsets, and the definition of two adjacent comb offsets is applicable to case 1 and is also applicable to a definition of adjacent comb offsets in other embodiments of this application. Furthermore, a definition of Petition 870250101444, dated 05 / 11 / 2025, p. 104 / 254 98 / 230 adjacent CS values ​​is also similar to the definition of adjacent comb offsets. To avoid repetition, details are not described.

[00269] For example, in case 1, if the network device configures or presets at least two of the three parameters an The following: the number of comb offsets included in the first set of comb offsets ^p, a comb offset interval between any two adjacent comb offsets, and the 1st comb offset (also called the reference comb offset) in the first set of comb offsets, the terminal device can determine the first set of comb offsets ^p based on these three parameters.

[00270] Optionally, this implementation can also be understood as follows: The first set of comb offsets ^p corresponding to the th group of ports includes at least one subset of comb offsets, and each subset of comb offsets includes one comb offset. The comb offset intervals between any two adjacent subsets of comb offsets are equal. The last subset of comb offsets and the 1st subset of comb offsets can also be called adjacent subsets of comb offsets. Two adjacent subsets of comb offsets can be understood as follows: The at least one subset of comb offsets is sorted in ascending order of comb offsets included in the subset of comb offsets.For a k-th subset of comb offsets and a (k - i)-th subset of comb offsets, a minimum value of a comb offset included in the k-th subset of comb offsets is greater than a maximum value of one. Petition 870250101444, dated 05 / 11 / 2025, p. 105 / 254 99 / 230 comb offset included in the very poor subset of comb offsets, where k is any one of 1, 2,..., or S, where S represents a total number of subsets. In this case, the kth comb displacement subset and the (ki)th comb displacement subset are adjacent comb displacement subsets, and a s1st comb displacement subset and the 1st comb displacement subset are adjacent comb displacement subsets. A comb displacement interval between two adjacent comb displacement subsets can be understood as a difference between the jth comb displacements included in the two adjacent comb displacement subsets, or an absolute value of a difference between the jth comb displacements included in the two adjacent comb displacement subsets.In one case, a comb displacement interval between two adjacent comb displacement subsets can be a difference between the 1st comb displacements included in the two adjacent comb displacement subsets, or an absolute value of a difference between the 1st comb displacements included in the two adjacent comb displacement subsets. For example, TCTC is 8, and the first comb displacement set φρ= {0,2,4,6} includes four comb displacement subsets:{0},{2},{4},{6}.A comb displacement interval between the 1st subset of comb displacements{0} and the 2nd subset of comb displacements{2} is 2, a comb displacement interval between the 2nd subset of comb displacements{2} and the 3rd subset of comb displacements{4} is 2, a comb displacement interval between the 3rd subset of comb displacements{4} and the 4th subset of comb displacements{6} is 2, and a comb displacement interval between the 4th subset of displacements. Petition 870250101444, dated 05 / 11 / 2025, page 106 / 254 100 / 230 of comb {6} and the 1st subset of comb displacements {°' is 2.

[00271] It should be noted that the above describes a definition of adjacent comb offset subsets, and the definition of adjacent subsets is applicable to case 1 and is also applicable to a definition of adjacent subsets in other embodiments of this application. Furthermore, a definition of adjacent CS subsets is similar to the definition of adjacent comb offset subsets. To avoid repetition, the details are not described. Additionally, the above describes a definition of a comb offset interval between two adjacent comb offset subsets, and the definition of a comb offset interval between two adjacent comb offset subsets is applicable to case 1 and is also applicable to a definition of a comb offset interval between two adjacent comb offset subsets in other embodiments of this application.Furthermore, a definition of a CS interval between adjacent CS subsets is also similar to the definition of a comb offset interval between two adjacent comb offset subsets. To avoid repetition, the details are not described.

[00272] Case 2: The first set of comb offsets ^p corresponding to the worst-case gate group includes at least one subset of comb offsets, the comb offsets included in each of the at least one subset of comb offsets are consecutive, and the comb offset intervals between any two adjacent subsets of comb offsets of the at least one subset of comb offsets are equal. That is, the comb offsets included in a subset of comb offsets are consecutive, and the subsets of comb offsets are equally spaced. The last subset of offsets of Petition 870250101444, dated 05 / 11 / 2025, p. 107 / 254 The 101 / 230 comb and the 1st subset of comb offsets can also be two adjacent subsets of comb offsets. That the comb offsets included in each subset of comb offsets are consecutive can be understood as meaning that the interval between adjacent comb offsets included in each subset of comb offsets is 1. For example, that the comb offsets included in a subset of comb offsets are consecutive can be understood as follows: The comb offsets included in the subset of comb offsets are sorted in ascending order of values, and a difference between a kth comb offset is cO ........ pe um (k- 1)th displacement of CO^, pentepé the followingCOpCOp 1. For example, CO2-CO1-1 It should be noted that, for a comb offset and a comb offset of 0, the comb offsets can also be considered consecutive. Optionally, all subsets of comb offsets include equal quantities of comb offsets. Optionally, a total comb quantity TC can be exactly divided by an interval between two adjacent subsets of comb offsets. For example, ^TC is 8, and the first set of comb offsets Vp = {0,1,4,5} includes two subsets: {0,1},{4,5} The comb shifts included in the 1st subset{0,1} are consecutive, the comb shifts included in the 2nd subset{4, 5} are consecutive, an interval between the 1st subset{0,1} and the 2nd subset{4,5} is 4, and an interval between the 2nd subset{4,5} and the 1st subset{0,1} is also 4.

[00273] For example, in case 2, if the network device configures or presets the following three parameters: a number of subsets of comb offsets, a Petition 870250101444, dated 05 / 11 / 2025, p. 108 / 254 102 / 230 number of comb offsets included in each subset of comb offsets and an initial comb offset (also called a reference comb offset) in each subset of comb offsets, the terminal device will be able to determine the first set of comb offsets ^p based on the three parameters. Alternatively, if the network device configures or predefines one or more of the following parameters: a number of subsets of comb offsets, a number of comb offsets included in each subset of comb offsets, an initial comb offset (also called a reference comb offset) from at least one subset of comb offsets, and a range between adjacent subsets of comb offsets, the terminal device will be able to determine the first set of comb offsets ^p based on the parameters.

[00274] It should be noted that the above describes a definition of consecutive comb displacements, and the definition of consecutive comb displacements is applicable to case 2 and is also applicable to a definition of consecutive comb displacements in other embodiments of this application. Furthermore, a definition of consecutive CS values ​​is also similar to the definition of consecutive comb displacements. To avoid repetition, the details are not described.

[00275] It can be understood that, for ease of description, a concept of a subset of comb displacements is introduced in case 1 and case 2. In some cases, a comb displacement that can be included in the first set of comb displacements ^p may have features in case 1 and case 2, but there is no limitation if there is a concept of a subset of comb displacements.

[00276] Case 3: The comb displacements included in the first Petition 870250101444, dated 05 / 11 / 2025, p. 109 / 254 103 / 230 comb offset set ^p corresponding to the 1st gate group are consecutive. To be more specific, the difference between adjacent comb offsets included in the first comb offset set ^p 1. For example, the first comb offset set is as follows: φρ= {0,1,2,3} For a specific definition of consecutive comb offsets, see the descriptions in case 2.

[00277] Optionally, in case 3, the first set of comb offsets ^p corresponding to the eighth gate group is obtained based on a reference comb offset kL TCC, startn„ dop ésimo grupo de portas epetapas de movimenta de pente do n , ,k7c - z , ,p ésimo grupo de portas, ondeCC,starté um número inteiro positivo. To be more specific, consecutive comb offsets can be obtained using the reference comb offset kpnCC,start, and the comb offsets can constitute the first set of comb offsets ^p.

[00278] Optionally, the comb offset step of the 1st port group can be indicated by the network device or can be specified in the protocol. The comb offset step can be understood as a jump value of a comb offset in a case where CO hopping is enabled. The comb offset step corresponds to the reference comb offset. CC, start represents an additional adjustment value of the reference comb offset kpCC, start based on the reference comb offset.

[00279] Optionally, the comb displacement step Petition 870250101444, dated 05 / 11 / 2025, page 110 / 254 104 / 230 represents an additional comb offset value or a comb offset difference relative to the reference comb offset, or the comb offset step represents an additional comb offset value or a comb offset difference relative to an initial comb offset, wherein the initial comb offset belongs to a set of comb offsets or a subset of comb offsets. When CO hopping is enabled, the comb offset step can be understood as an adjustment value or a difference of a comb offset based on a predefined or configured comb offset corresponding to an SRS port (or a corresponding comb offset in a case where CO hopping is disabled). The comb offset step may also be called the comb offset difference or comb offset difference value.

[00280] Optionally, the k*TC,start reference comb offset of the pth port group can be indicated by the network device or can be specified in the protocol. The k*TC,start reference comb offset of the pth port group can be considered an initial comb offset or an initial position of an available comb offset area when the pth port group performs CO hopping. When the k*TC,start reference comb offset of the pth port group is predefined in the protocol, the kpreferenceTC,start comb offset can be 0, 2, or 4.

[00281] Optionally, the reference comb offset kp TC,start of the fifth group of ports can be determined based on some parameters configured by the network device. For example, the terminal device can obtain the offset of Petition 870250101444, dated 05 / 11 / 2025, page 111 / 254 105 / 230 ^0 reference comb TC, start of the first group of ports based on . . K. at least one of a total number of combs TC NSRS configured by the network device, AP, a kTC comb offset from a reference port, an offset value. CS cs,max cyclic maximum RS CS n or a cyclic offset value SRS of a reference port in the pth port group. The reference port in the pth port group can be a port with the lowest port index in the pth port group. For example, kpkpTC,start can be TC in formula (3). To be specific, the kp terminal device can determine TC obtained according to kpkp formula (3) as TC,start. To be specific, TC can be understood as a comb offset used when the terminal device does not perform CO hopping. In other kp words, the reference comb offset TC,start of the first set of comb offsets used when the terminal device needs to perform CO hopping can be the comb offset determined when the terminal device does not perform CO hopping. The comb offset used when the terminal device does not perform CO hopping can alternatively be a comb offset configured by the network device by default.In one implementation, all ports in the th group of ports correspond to the same comb offset of kpreferenceTC,start.

[00282] The following describes the first set of comb offsets defined ^p in case 3 using (a) and (b).

[00283] (a) The first set of comb displacements ^p Petition 870250101444, dated 05 / 11 / 2025, p. 112 / 254 106 / 230 corresponding to the th group of ports is obtained based on at least one of the total number of TCTC combs, the k pn offset of the reference TC comb, the start of the th group of ports or the comb offset steps of the th group of ports, the first set of comb offsets includes np n comb offsets, the comb offsets are in n a one-to-one correspondence with displacement aspetapas n„ , „ . , . ... K, , . The comb offset is a positive integer less than 1C. That is, a comb offset can be determined based on a comb offset step and the reference comb offset of kpnTC,start. Optionally, the comb offset steps are consecutive. To be specific, the interval between two adjacent comb offset steps is 1.

[00284] Optionally, the network device can send the initial indication information and the terminal device can receive the initial indication information. The initial indication information indicates the total number of memory sticks. TC

[00285] Optionally, the network device can send secondary indication information, and the terminal device can receive the indication information. The secondary indication information n They can indicate the length p of the first set of comb displacements ^pe. np can also be referred to as the number of comb displacements included in the first set of comb displacements ^p. Optionally, the length np of the first set of comb displacements ^p. Petition 870250101444, dated 05 / 11 / 2025, page 113 / 254 107 / 230 can be preset. For example, the length of the first set of comb offsets can be preset as 2, 4, or 8.

[00286] Optionally, the network device can indicate aspn Comb displacement steps, or comb displacement steps, can be specified in the protocol. When on The network device indicates the comb displacement aspects, . . . . . the network device can directly indicate the n aspects. Comb offset, or it can indirectly indicate the comb offset steps. For example, the network device may indicate a maximum value of the comb offset steps, . . . . n„ and the terminal device may determine consecutive comb offset steps based on the indicated maximum value of the comb offset steps. The network device may alternatively indicate the comb offset steps using a bitmap. A number of bits included in the bitmap is TC,, and each bit corresponds to a value in a set of available comb offset steps {θ^ ' tr ^} . A bit value in the bitmap being 1 indicates that a step value corresponding to the bit in the set of available comb offset steps n is a comb offset value of the comb offset steps.

[00287] Optionally, the first set of displacements of Vp ={k(0),' -(1),k(2),-^o(n —1)} kp(k) comb is as follows:p'v'> , where CO 7 represents a comb shift with an index of k, or the kth comb shift in the first set of comb shifts. To be more specific, the first set of Petition 870250101444, dated 05 / 11 / 2025, p. 114 / 254 108 / 230 comb offsets may include pcomb offsets, and a specific form of pcomb offsets may not be limited. When the first set of comb offsets, HF· ^ ={kP°(0)'(1)'kP° (2),'>kCΛ^-O} Ί is defined p vp, optionally, the terminal device sends the SRS based on at least one comb offset in the first set of comb offsets ^p corresponding to the op th group of ports in S510 includes: The terminal device determines k0p = «^ + kCo(f(«SRS)) and sets an initial domain position kp = kp + «FH + «RPFS of the frequency 0 0offsetLjfset to which the «th group of gates is mapped, in FHRpFSque«offset «Offset represents a sub-band shift in the frequency domain.

[00300] Optionally, the first set of comb offsets ^pcorresponding to the fifth gate group is as follows: {kTc,start , (kTC,start+1)mod KTC , (kTC,start+ 2)mod KTC < ' '\k / p—art+np—1)mod KTC} 0,1,2,·, η -1 ~ npsao aspetapas de movimentação de pente.

This implies that a comb offset occupied by a kpum CO that does not support CO hopping is less than TC,start. In other words, the network device can configure the first set of comb offsets ^p for the terminal device based on the CO that does not support CO hopping. For example, as shown in Figure 6, a gate group 1 includes a gate 0 and a gate 2, a reference comb offset of gate 0 and gate 2 is a CO 0, a gate group 2 includes a gate 1 and a gate 3, and a parameter comb offset of gate 1 and gate 3 is a CO 2. COs that do not support CO hopping are CO 2 and CO 3 which correspond to a CS 0 and a CS 6, and CO 1 ^.1 corresponding to a CS 3 and a CS 9.TC,start of gate group 1 is CO 0, and two comb offset steps corresponding to gate group 1 are {0, 1}.Therefore, a first set of comb shifts corresponding to gate group 1 is as follows: ^1 {θΊ}.

To be specific, a first comb offset selected by the terminal device from the first set of comb offsets ^p is less than or equal to kpa tc,start. This implies that a CO that does not support CO hopping is kp greater than TC·start. In other words, the network device can configure the first set of comb offsets ^p for the terminal device based on the CO that does not support CO hopping.

[00302] Optionally, it can be specified in the protocol that the first set of comb offsets ^p can be {kTc, start , (kTC, start + 1)mod KTC , (kTC, start +2)mod KTC ,·,^^art + np - 1)mod KTC} {kTC,start ,(kTC,start - 1) mod KTC ,(kTC,start -2)mod KTC O (kTC,start - np + 1) mod KTC} ç. A network device can send third-party indication information, and the terminal device can receive third-party indication information. This third-party indication information indicates one of two sets used as the first set of comb offsets ^p. In other words, two possibilities for the first set of comb offsets ^p can be specified in the protocol. One of the two possibilities used by the terminal device can be indicated by the third-party indication information.

[00303] After the terminal device determines the first set of comb offsets ^pdop ésimo group of ports, in a first and a second implementation, the comb offsets of all ports in the p ésimo group of ports can be equal and all are a first comb offset. In a third implementation, different ports in the p groups of ports can have different comb offsets. In this way, Petition 870250101444, dated 05 / 11 / 2025, pp. 123 / 254 117 / 230 A CO occupied by a port sending an SRS can be more random, so the probability of overlap between the CO occupied by the port sending the SRS and a CO of a terminal device that does not support CO hopping is low, and interference can be reduced. The two implementations are described below.

[00304] In the first implementation, optionally, in (a), the terminal device sends the SRS based on at least one comb offset in the first set of comb offsets ^p corresponding to the op-th group of ports in S510 includes: The terminal device generates a first value based on an n total number of comb displacements included in the first set of comb displacements ^p, where a range of values ​​for the first value is [0, np -1]. The terminal device determines, from the first set of comb offsets ^p, a first comb offset corresponding to the first value, where a comb offset of each port in the pth group of ports is the first comb offset. The terminal device sends the SRS based on the first comb offset. Optionally, a value in [0, np-1] corresponds to a comb shift in the first set of comb shifts ^p. In other words, pvalues ​​in [0, np-1] are in a one-to-one correspondence with the comb offsets in the first set of comb offsets ^p. To be specific, after the terminal device determines the first set of comb offsets ^p, for a specific SRS transmission time, the terminal device needs to determine a comb offset of the nth group of Petition 870250101444, dated 05 / 11 / 2025, pp. 124 / 254 118 / 230 ports starting at the first set of comb offsets ^p. The terminal device can obtain a first value based on the total number of comb offsets; determine, from the first set of comb offsets ^p based on the first value, a first comb offset corresponding to the op-th group of ports; and send the SRS based on the first comb offset. Optionally, during the determination, from the first set of comb offsets ^p based on the first value, of the first comb offset corresponding to the op-th group of ports, a comb offset that is in the first set of comb offsets ^pe that corresponds to the first value can be determined as the first comb offset. Optionally, the first value can be a random value. Optionally, the reference comb offsets of all ports in the op-th group of ports are equal.To be more specific, the initial comb offsets of all ports in the 10th port group are the same CO, and the initial comb offsets of all ports in the 10th port group are equal. Optionally, the reference comb offsets of different port groups may be different. Optionally, sending the SRS based on the first comb offset can be understood as sending the SRS based on the first comb offset at one sending time. At another sending time, the terminal device may determine another comb offset from the first set of comb offsets ^p based on another value and send an SRS based on the other comb offset. To be more specific, after determining the first set of offsets. Petition 870250101444, dated 05 / 11 / 2025, pp. 125 / 254 119 / 230 of comb ^p, the terminal device can select a comb offset from the first set of comb offsets ^p at each periodicity to send an SRS and send, based on the selected comb offset, an SRS at each periodicity to send an SRS. Optionally, at different sending times, the terminal device can select the same comb offset or different comb offsets from the first set of comb offsets ^p. This is not limited in this embodiment of this request. For example, as shown in Figure 6, the first SRS resource used by the terminal device to send the SRS corresponds to four ports: a port 0, a port 1, a port 2, and a port 3. A group of ports 1 includes port 2 and port 0. In other words, the 1st group of ports includes port 2 and port 0. A group of ports 2 includes port 3 and port 1.In other words, the 2nd gate group includes gate 3 and gate 1. A diagram (a) in Figure 6 shows a reference comb offset of a gate included in each gate group and also shows that COs that do not support CO hopping occupy a CO 2 and a CO 3 of a CS 0 and a CS 6, and a CO 1 of a CS 3 and a CS 9. A reference comb offset of gate group 1 is a CO 0, and a reference comb offset of gate group 2 is CO 2. For the first group of gates, ^1 = {0,1}, and a length n, ^1 z1de1é 2. For the 2nd group of doors, ^2 = {2,3,0} , and a length u ^2 of 2 3. The terminal device can determine that a first random value of the gate group 1 at the first transmission moment is 1, and the terminal device can determine that a first comb offset of the 1st gate group Y1 at the first transmission moment is the 1st comb offset {1} in ^ ={0,1}, in Petition 870250101444, dated 05 / 11 / 2025, pp. 126 / 254 120 / 230 that the 0th comb offset in ^1 {θΊ}can be{0}terminal device can determine that a first random value of the gate group 2 at the first moment of transmission is 1, and the terminal device can determine that a first comb offset of the 2nd gate group r2 at the first moment of transmission is the 1st comb offset{3}where the 0th comb offset in Ψ2 = {2,3,0} can be {2}, The second comb shift can be {0}. Therefore, the first transmission moment is shown in a diagram (b) in Figure 6. A CO from the 1st gate group is CO 1, and a CO from the 2nd gate group is CO 3. The terminal device can determine that a first random value from gate group 1 at a second transmission moment is 0, and the terminal device can determine that a first comb shift from the 1st gate group ^1 at the second transmission moment is the 0th comb shift {0} in ^1={0,1}, where the 1st comb shift in ^1={0,1} can be {1}. The terminal device can determine that a first random value of gate group 2 at the second transmission moment is 2, and the terminal device can determine that a first comb offset of the 2nd gate group φ2 at the second transmission moment is the 2nd comb offset {0} in φ- ={2,3'0!, where the comb offset 0 in ^2={2,3,0} can be {2}, and the comb offset 1 can be {3}.Therefore, the second transmission moment is shown in a diagram (c) in Figure 6. A CO of the 1st gate group is CO 0, and a CO of the 2nd gate group is CO 0. The terminal device can determine that a first random value of gate group 1 at a third transmission moment is 1, and the terminal device can determine that a first comb shift of the 1st gate group φι at the third transmission moment is the comb shift {1}1 in Ψ1={0,1}, where o. Petition 870250101444, dated 05 / 11 / 2025, pages 127 / 254 121 / 230 comb shift 0 in φ1 = {0,1} can be {0}. The terminal device can determine that a first random value of gate group 2 at the third transmission moment is 0, and the terminal device can determine that a first comb shift of the 2nd gate group φ2 at the third transmission moment is the 0th comb shift '2} in φ2 = {2,3,0}, where the 2nd comb shift in φ2 = {2,3,0} can be '0', and the 1st comb shift can be '3}. Therefore, the third transmission moment is shown in a diagram (d) in Figure 6. A CO of the 1st gate group is CO 1, and a CO of the 2nd gate group is CO 2. By analogy, a diagram (e) in Figure 6 and a diagram (f) in Figure 6 can be obtained. The first sending moment, the second sending moment, or the third sending moment can be a moment when an SRS is sent. It can be understood that all the diagrams in the Figure correspond to different f(nSRS), and different diagrams in Figure 6 corresponds to different shipping times. Alternatively, the terminal device selects, based on f(nSRS), a way from diagram (a) to diagram (f) in Figure 6 to send an SRS.

[00305] Optionally, in (a), the network device receives the SRS based on at least one comb offset in the first set of comb offsets φ corresponding to the worst group of ports in S510 including: The network device generates a first value based on a total number of comb offsets included in the first set of comb offsets φ where a range of values ​​for the first value is [0, np - 1] The network device determines, from the first set of comb offsets φ, a first comb offset corresponding to the first value, where a comb offset of each port in the th group of Petition 870250101444, dated 05 / 11 / 2025, pp. 128 / 254 122 / 230 ports is the first comb offset. The network device receives the SRS based on the first comb offset. The first set of comb offsets ^p on the network device side is the same as the first set of comb offsets ^p on the terminal device side, and the way the network device determines the first comb offset from the first set of comb offsets ^p is the same way the terminal device determines the first comb offset. To avoid repetition, the details are not described.

[00306] The network device can configure, for the terminal device, a startup identity (identity, ID) to generate the first value, and the terminal device generates the first value based on the startup identity; or the network device can generate the first value based on the startup identity. In this way, the first comb offsets that correspond to the first values ​​and that are determined by the network device and the terminal device from the first set of comb offsets ^p are equal. Therefore, the network device can receive the SRS based on the first comb offset.Optionally, the first value may also be related to one or more of a slot index corresponding to an SRS transmission moment, an OFDM symbol index corresponding to an SRS transmission moment, an OFDM symbol offset corresponding to an SRS transmission moment, an SRS transmission periodicity, a system frame index corresponding to an SRS transmission moment, or an SRS repetition factor. For the generation of the first value, see the previous descriptions.

[00307] In the second implementation, the network device can alternatively indicate comb offsets in the first Petition 870250101444, dated 05 / 11 / 2025, pp. 129 / 254 123 / 230 set of comb offsets ^p using a bitmap. The number of bits included in the bitmap is KC, and each bit corresponds to a value of the oneth comb offset in the first set of comb offsets ^p. A bit value in the bitmap being 1 indicates that a comb offset corresponding to the SRS sending is a comb offset value that is in the first set of comb offsets ^p that corresponds to the bit. To be more specific, after the terminal device determines the first set of comb offsets ^p, for a specific SRS sending time, the terminal device needs to determine, from the first set of comb offsets ^p based on the bitmap, a first comb offset corresponding to the oneth port group; and send the SRS based on the first comb offset.

[00308] Optionally, the network device can determine a first comb offset of the 10th group of ports based on a comb offset that is in the first set of comb offsets ^pe that is indicated by the bitmap, and receive the SRS based on the first comb offset.

[00309] In the first and second implementations, the comb offsets of all ports in the th group of ports are the same and correspond to the first comb offset. In some possible implementations, the comb offsets of all ports in the th group of ports may alternatively be different. This is not limited to the present embodiment of this application.

[00310] In the third implementation, the ésimo group of ports includes m„ _ m„pports. A comb offset of each of the pports in the first set of comb offsets ^pesta Petition 870250101444, dated 05 / 11 / 2025, pp. 130 / 254 124 / 230 relates to an index of a cyclic shift group to which a corresponding cyclic shift value for the gate belongs. The first SRS feature corresponds to T groups of cyclic shift values. A group of cyclic shift values ​​corresponds to a cyclic shift group index. The T groups of cyclic shift values ​​correspond to a total of T cyclic shift group indices. The T cyclic shift group indices can be, ,, where T is a positive integer. That is, a set of comb shifts for each gate in the pth group of gates in the first set of comb shifts ^p is related to an index of a cyclic shift group to which a corresponding cyclic shift value for the gate belongs.Since different ports in the pth group of ports can belong to different groups of cyclic offset values, different ports can have different comb offsets. In this way, a comb offset used by the pth group of ports to send an SRS can be more random, to help reduce interference. Optionally, each of the T groups of offset values... CS, max / p cyclic includes SRS values ​​of cyclic displacement. Optionally, the cyclic displacement values ​​included in each group of cyclic displacement values ​​are cyclic displacement values ​​with consecutive cyclic displacement values. For example, RS all cyclic displacement values ​​are divided into T = 4 groups of cyclic displacement values, and each group of cyclic displacement groups includes three cyclic displacement values. The three groups of cyclic displacement values ​​include, respectively, the following cyclic displacement values: {CS 0, CS 1, CS 2}, {CS 3, CS 4, CS 5}, {CS 6, CS 7, CS 8} and {CS Petition 870250101444, dated 05 / 11 / 2025, pp. 131 / 254 125 / 230 {CS 9, CS 10, CS 11}. A cyclic shift group index corresponding to the 1st group of cyclic shift values ​​{CS 0, CS 1, CS 2} can be 0. A cyclic shift group index corresponding to the 2nd group of cyclic shift values ​​{CS 3, CS 4, CS 5} is 1. A cyclic shift group index corresponding to the 3rd group of cyclic shift values ​​{CS 6, CS 7, CS 8} is 2. A cyclic shift group index corresponding to the 4th group of cyclic shift values ​​{CS 9, CS 10, CS 11} is 3.

[00311] Optionally, a value for the quantity T of groups of cyclic offset NSR values ​​can be a quantity ap of antenna ports, or it can be one of 1, 2, 4, or 8. The quantity T of groups of cyclic offset values ​​can be configured by the network device for the terminal device using indication information, or it can be a predefined value.

[00312] Optionally, a pentep offset of a gate m^ mpésimo das pportas pente ^pé obtained with in the first set of kpbase offsets in TCcorrespondente mJàp ésimaporta and an index Tj of a cyclic offset group to which the value , , . , s mj. . of cyclic displacement corresponding to the 1st port it belongs to. kpTC is obtained based on at least one of the total number of K NSRS combs TC configured by the network device, ap, , . kr^. , . , , . The displacement of the reference gate, the value of cs, max n maximum cyclic displacement RS or the value of displacement c cs pp cyclic SRS of the reference gate in the p th gate group. TC can be obtained according to formula (3). In this case, the m7jp gate in formula (3) can be replaced by the p th gate. By Petition 870250101444, dated 05 / 11 / 2025, pp. 132 / 254 126 / 230 example, cs, max _ , ~ nRS =1Z· • As shown in a diagram (a1) in Figure 7, gate 0, gate 1, gate 2, and gate 3 are a group of gates, and a first set of comb offsets for the group of gates is as follows: φρ= {0,1,2,3} All CSs are divided into a total of four CS groups. An index of CS group 1 is 0, and CS group 1 includes CS 0, CS 1, and CS 2. An index of CS group 2 is 1, and CS group 1 includes CS 3, CS 4, and CS 5. An index of CS group 2 is 2, and CS group 3 includes CS 6, CS 7, and CS 8. An index of CS group 4 is 3, and CS group 4 includes CS 10, CS 11, and CS 11. CS 6 of port 0 belongs to group 1. CS with an index of 2. CS 9 on port 1 belongs to the CS group with an index of 3. CS 0 on port 2 belongs to the CS group with an index of 0. CS 3 on port 3 belongs to the CS group with an index of 1. Different ports included in the port group correspond to different CS group indices. Therefore, after the CO hop is enabled, at the same time of sending... In SRS, different ports correspond to different comb shifts or comb shift steps. For example, based on CS group index 0, a CO corresponding to port 2 does not jump and is still a CO 0; based on CS group index 1, a CO corresponding to port 3 needs to jump to a CO 1; based on CS group index 2, a CO corresponding to port 1 needs to jump from CO 0 to a CO 2; and based on CS group index 3, a CO corresponding to port 1 needs to jump from CO 0 to a CO 3. The CSs, obtained by hopping, of the ports are shown in a diagram (a2) in Figure 7. Similarly, before CO hopping is enabled, the COs of the port group are all a CO 1; and the COs, obtained by means of a jump based on the CS groups to which the gates belong, of the gates are shown in a diagram (b2) in Figure 7. The COs of the gates in diagram (a1) and in diagram (b1) of Figure 7 can be Petition 870250101444, dated 05 / 11 / 2025, pp. 133 / 254 127 / 230 kpTC calculated according to formula (3). For example, in diagram (c1) of Figure 7, a gate group 1 includes a gate ^. 1 and a gate 0,TC is a CO 1, a CS 6 of gate 0 in gate group 1 belongs to a CS group with index T1 of 2, and a CS 0 2 of gate 2 belongs to a CS group with index T of 0. A first set of comb shifts of gate group η ' > , Φλ — {1,2,3} n, — 3 T modn , g mod 3 \ ' ο tx , . It is as follows: 1 1; 1; e1(2mod3) e 2. Therefore, a CO 3 can be obtained after gate 0 jumps through two COs. Since Tmodn1(0mod3) e 0, gate 2 may not jump and is still CO 1. Therefore, the COs, obtained by jumping, from gate 0 and gate 2 are shown in diagram (c2) of Figure 7. In diagram (c1) of Figure 7, a group of gates 2 includes a gate 1 and a gate 3, 2TC is a CO 1, a CS 9 of gate 1 in gate group 2 belongs to a CS group with an index T1 of 3, and a CS 3 of gate 32 belongs to a CS group with an index T of 1. A first set of comb offsets of gate group 2 is the I φ^ — {0,1,2} n, — 3 T mod n , \ mod 3 \zn τί . The following:2 1;1; e1(3mod3) is 0. Therefore, gate 1 does not jump, and is still the CO. Since T modn1(1mod3) is 1, gate 3 jumps by a CO, and CO 1 is obtained. Therefore, the COs, obtained by jumping, from gate 1 and gate 3 are shown in diagram (c2) in Figure 7.

[00313] Optionally, the comb offset n mJpdapésimaporta , m„ . .Ί, m daspportas in the first set of comb offsets ppk p is obtained based on TCo the corresponding cyclic offset group index TmJpésimaporta is specifically as follows: The comb offset njpmj. . m dap ésimaporta dasp Petition 870250101444, dated 05 / 11 / 2025, pages 134 / 254 128 / 230 gates in the first set of comb offsets ^p is obtained z, τJ, kC by performing a modulo operation on T based on TC. For example, a comb offset that is in the first set of comb offsets ^pe corresponds to a value obtained by means of TJmod n , . The foot is determined as the comb displacement nJjp. That is, when T is greater than nJp, it can be determined based on n„p, the comb displacement modulus operation.

[00314] Optionally, the pth group of ports includes mpports, and a comb offset of each of the pports in the first set of comb offsets ^p is related to a cs, Jn cyclic offset SRS value corresponding to the port. For example, cs, Jn SRS can be determined according to formula (6). That is, a set of comb offsets, in the first set of comb offsets ^p, of each port in the pth group of ports is related to a cyclic offset value of the port. Since different ports in the pth group of ports can belong to different cyclic offset values, different ports can have different comb offsets. In this way, a comb offset used by the pth group of ports to send an SRS can be more random, to help reduce interference. Different ports included in the port group correspond to different cyclic offset values.Therefore, after the CO hop is enabled, at the same time of SRS transmission, different ports correspond to different comb offsets or comb offset steps. njm.i Optionally, a pentepde umap ésimaporta displacement Petition 870250101444, dated 05 / 11 / 2025, pages 135 / 254 129 / 230 , m„ ...Ί, 0„ daspportas in the first set of comb displacementsΎρkPn, ' is obtained based on TC and a cyclic displacement value SRSmP. kp corresponding to the 1st port.

In this case, the gate p in formula (3) can be replaced mj . . ... , by the p th gate. One way to obtain the njp comb offset based on the cyclic offset value is similar to the nj way of obtaining the pb comb offset based on the cyclic offset group index. To avoid repetition, the details are not described in this embodiment of this application.

Similarly, the terminal device can obtain the njde pentepcom offset.

To be specific, the terminal device can determine the second value, and determine that the worst comb shift step is(1)f(nsRs). Optionally, it is specified in the protocol that the value of b is 0; or it can be specified in the protocol that the value of b is 1. Optionally, the network device can Petition 870250101444, dated 05 / 11 / 2025, pp. 137 / 254 131 / 230 configure the value of b as 0, or the network device can n^ configure the value of b as 1. Optionally, the ap-th pen offset step is not limited to being determined based on the second value. The ap-th pen offset step of the pen offset steps can alternatively be n determined in another way. For example, the comb displacement steps corresponding to the 8th group of gates n The network device may specify the corresponding port offset steps for the fifth group of ports, or the protocol may specify them. One way for the terminal device to determine the corresponding port offset steps for the fifth group of ports is not limited in this embodiment of this request. The network device may configure an initialization identity (identity, ID) for the terminal device to generate the second value, and the terminal device generates the second value based on the initialization identity; or the network device may generate the second value based on the initialization identity. In this way, the network device and the terminal device determine the same port offset steps based on the second value.Optionally, the second value may also be related to one or more of the following: a slot index corresponding to an SRS transmission moment, an OFDM symbol index corresponding to an SRS transmission moment, an OFDM symbol offset corresponding to an SRS transmission moment, an SRS transmission periodicity, a system frame index corresponding to an SRS transmission moment, or an SRS repetition factor. For the generation of the second value, see the previous descriptions. Petition 870250101444, dated 05 / 11 / 2025, pages 138 / 254 132 / 230

[00317] To be specific, a comb offset in the first set of comb offsets ^p corresponding to the oth gate group corresponds to a comb offset step, n„, and the terminal device can obtain the comb offset steps n„ and determine, based on the comb offset steps k„ and the reference comb offset TC·start, a specific comb offset step that should be used to determine a first comb offset. In other words, in case 2, the terminal device does not need to sequentially determine the p comb offsets included in the first set of comb offsets ^p, but the terminal device needs to learn about the p„. To be specific, in case 1, the combs included in the first set ^p represent the first set of n„, and in case 2, the steps corresponding to the first set ^p represent the first set of n„ offset steps. 1, comb displacements comb displacements ^p; comb displacement of comb displacements of comb ^p. Although the first set of comb displacements ^ps is represented in different forms in case 1 and case 2, case 2 also implies that the first set of comb displacements ^p can alternatively be the case in case 1. For example, in , ,Ί. 4- 0,1,2,·, η -1, the comb displacement steps being, in other words, the value of b being 0, implies that the first set of comb displacements ^p is {kTC,start,(kTC,start + 1)mod KTC ,(kTC,start +2)mod KTC , ' ' (kTC,start + np — 0mod KTC}n ' ' ' ' ; and asp Petition 870250101444, dated 05 / 11 / 2025, pp. 139 / 254 133 / 230 comb displacement steps being 0, -1, -2,---,—np+1 in other words, the value of b being 1, implies that the first set of comb displacements is {kTC, start, (kTC, start 1)modKTC , (kTC, start2) mod KTC ,''{^TC,start np+ 1) mod KTC}

The terminal device sends the SRS based on the frequency domain starting position to which the op-th port group is mapped. For different kpreference TC,start port offsets, the terminal device determines the first port offset in different ways.

[00319] Optionally, the first set of comb displacementsOp may correspond to a first set of comb displacement steps.

This can ensure that the network device can receive the SRS sent by the terminal device.

[00334] It can be understood that, in this modality of this request, a set of comb offsets for each group of ports can be in any format, and is not limited to the cases described in the three previous cases. For example, the comb offsets included in the set of comb offsets for each group of ports can be any comb offsets ranging from KTc— 1 to TC.

[00335] Optionally, in the previous 500 method, the first set of comb offsets ^p corresponds to an initial comb offset value of the pth gate group and a first set of comb offset bias values. In other words, the first set of comb offsets ^p can be determined based on the initial comb offset value of the pth gate group and the first set of comb offset bias values. For example, the initial comb offset value of the pth gate group is 1, and the first set of comb offset bias values ​​is {0, 1}. In this case, the first set of comb offsets is {1, 2}. To be more specific, the terminal device can send the SRS based on at least one comb offset in the first set of Petition 870250101444, dated 05 / 11 / 2025, pp. 154 / 254 148 / 230 comb offsets ^p, or it can send the SRS based on the initial comb offset value of the nth gate group and the first set of comb offset bias values; or the terminal device can determine the first set of comb offsets ^p based on the initial comb offset value of the nth gate group and the first set of comb offset bias values, and send the SRS based on at least one comb offset in the first set of comb offsets ^p.Optionally, the terminal device can send the SRS based on the initial comb offset value of the worst-case group of ports and the first set of comb offset bias values ​​includes: The terminal device selects a first comb offset bias value of the worst-case group of ports from the first set of comb offset bias values, determines a first comb offset value based on the initial comb offset value of the worst-case group of ports and the first comb offset bias value of the worst-case group of ports, and sends the SRS on the first comb offset value.

[00336] Optionally, the initial comb offset values ​​of all ports in the worst-case port group are equal, and the initial comb offset values ​​of different port groups may be different. To be more specific, during port splitting, ports belonging to the same comb may be considered as one port group, and ports on different combs may be split into different port groups. For example, as shown in Figure 8, four ports corresponding to the first SRS feature are ports 0, 1, 2, and 3. Among the four ports, 0 and 2 are a port group 1, Petition 870250101444, dated 05 / 11 / 2025, pages 155 / 254 149 / 230 and 1 and 3 are a gate group 2. As shown in diagram (a) in Figure 8, an initial comb offset value of gate group 1 is 0, an initial comb offset value of gate group 2 is 4, and the first set of comb offset bias values ​​is {0, 1, 2}. In this case, a set of comb offsets corresponding to gate group 1 is {0, 1, 2}, and a set of comb offsets corresponding to gate group 2 is {4, 5, 6}. For example, as shown in diagram (b) of Figure 8, for the 1st SRS transmission occasion, the COs of the ports in port group 1 are a CO 1, and the COs of the ports in port group 2 are a CO 5. For another example, as shown in diagram (c) of Figure 8, for the 2nd SRS transmission occasion, the COs of the ports in port group 1 are a CO 2, and a CO of port group 2 is a CO 6.

[00337] Optionally, for an SRS transmission occasion, the bias values ​​of the first comb offset of different gate groups in the set of bias values ​​of the first comb offset may be the same or certainly different. This is not limited in this embodiment of this application.

[00338] The first set of comb offset bias values ​​is discussed below in two cases.

[00339] Case 1: The comb offset bias values ​​included in the first set of comb offset bias values ​​are consecutive.

[00340] Optionally, the first set of L^ comb displacement bias values ​​includes 1 biases of L consecutive cyclic offsets, where g1 is greater than or equal to . . K^ and less than or equal to the total number of combs TC. For example, the first set of offset bias values ​​of L pente e {0, 1, 2} eg,1 é 3. To be specific, a difference CO between a k-th comb displacement polarization value p Petition 870250101444, dated 05 / 11 / 2025, pp. 156 / 254 150 / 230 ,, ............COe one (ki)th comb displacement bias value p that are included in the first set of values ​​of COk. - CO' = 1 comb displacement polarization is as follows: pp .

When the first set of comb shift bias values ​​is {0,1modKTC,---—Lgj —1)modKTc} the first set of comb shifts ^p corresponding to the th gate group corresponds to a direction in which a comb shift increases from the initial comb shift value of the th gate group kpp gates. For the initial comb shift value TC of the th gate group, see the previous descriptions of formula (3). To avoid repetition, the details are not described. kp Optionally, the initial port offset value TC of the worst-case group of ports can alternatively be indicated by the network device. This is not limited to this mode. Petition 870250101444, dated 05 / 11 / 2025, pages 157 / 254 151 / 230 order.

[00343] Optionally, the first set of comb shift bias values ​​is {0, -1mod KTc,···,(- Lgl+1) mod KTc} , in which mod(') is a modulo operation. When the first set of comb shift bias values ​​is {0, -1 mod KTc, +1) mod KTc}, The first set of comb offsets ^p corresponding to the th group of gates corresponds to a direction in which a comb offset decreases from kpp of the initial comb offset value TCdop th group of kpp gates. For the initial comb offset value TCdop th group of gates, see the previous descriptions of formula (3). To avoid repetition, the details are not described. kp Optionally, the initial comb offset value TCdo pesimogrupo de portas can alternatively be specified by the network device. This is not limited to this application mode.

[00345] For example, the initial frequency domain position to which the worst gate group is mapped is Petition 870250101444, dated 05 / 11 / 2025, pages 158 / 254 152 / 230 n^N™ + (kp+ ket + n,''offset)modKTC shift sc ic offset srs io • nNRc

To be specific, for an SRS send occasion, the first comb offset bias value is a comb offset bias value in the first set of comb offset bias values. See the example shown in Figure 8. For example, in diagram (b) of Figure 8, on an SRS send occasion, the first comb offset bias values ​​of port group 1 and port group 2 are 1. For another example, in diagram (c) of Figure 8, on the 1st SRS send occasion, the first comb offset bias values ​​of port group 1 and port group 2 are 2.

'combOffsetHoppingSubset',g,1 is a value configured by the network device or is a predefined value. If the network device does not configure 'combOffsetHoppingSubset', 4114C. To be more specific, the terminal device may determine a . L, . . . ....... value deg,1 depending on whether the network device is configured Lt 'combOffsetHoppingSubset'. In different cases, the value of deg1 varies. The network device is being configured. Petition 870250101444, dated 05 / 11 / 2025, pages 159 / 254 153 / 230 'combOffsetHoppingSubset' indicates that CO subset hopping is enabled, and the network device can configure a number of comb offset bias values ​​included in the first set of comb offset bias values, or a number of comb offset bias values ​​included in the first set of comb offset bias values ​​can be predefined.

[00420] The first set of comb offsets ^p described above corresponds to the initial comb offset value of the th gate group and the first set of comb offset bias values. To be more specific, the first set of comb offset bias values ​​can be combined with method 500, or the first set of comb offset bias values ​​can be an independent mode.

[00421] In one possible implementation, to solve an interference problem, the interference between SRS sequences is randomized by means of cyclic shift hopping (CS hopping), and a good interference randomization effect can be achieved by randomizing the interference between SRS sequences by means of CS hopping. However, in a real-world application scenario, there is a terminal device that supports CS hopping and a terminal device that does not support CS hopping. In this application, the terminal device that supports CS hopping is a terminal device that can randomize the interference between SRS sequences by means of CS hopping. In other words, the terminal device that supports CS hopping has the capability or function to randomize the interference between SRS sequences by means of CS hopping.In this request, the terminal device that does not support CS hopping is a terminal device that cannot randomize interference between SRS sequences through CS hopping. In other words, the terminal device that... Petition 870250101444, dated 05 / 11 / 2025, pp. 180 / 254 174 / 230 does not support CS hopping and lacks the capability or function to randomize interference between SRS sequences through CS hopping. When the network device configures, in the same CS for multiplexing, an SRS port corresponding to the terminal device that supports CS hopping and an SRS port corresponding to the terminal device that does not support CS hopping, the channel estimation performance of the two terminal devices can be seriously degraded. Therefore, how to avoid the degradation of channel estimation performance in the previous case, by making the most of the interference randomization effect of cyclic shift hopping, is an urgent problem to be solved. In CS hopping mode, the CS bands in which the terminal device ports perform CS hopping to send the SRS are the same band.For example, as shown in Figure 10, a UE SRS feature can correspond to four ports: a port 0, a port 1, a port 2, and a port 3. A CS range in which port 0, port 1, port 2, and port 3 perform CS hopping can be {CS 0, CS 1, CS 2, CS 3, CS 4, CS 5, CS 6, CS 7, CS 8, CS 9, CS 10, CS 11}. A port 0 CS is CS 6, a port 2 CS is CS 0, a port 3 CS is CS 3, and a port 1 CS is CS 9. UE port CSs that do not support CS hopping are CS 2, CS 5, CS 5, and CS 11. All four ports can move right by two CSs. After the movement, a CS from port 0 becomes CS 8, a CS from port 1 becomes CS 11, a CS from port 2 becomes CS 2, and a CS from port 3 becomes CS 5. Consequently, the CSs obtained through hopping from the ports overlap with the CSs occupied by the UE, which does not support CS hopping, and transmission on the CSs is affected.

[00422] In other words, in the previous implementation, to reduce interference, the CSs through which the ports used by the terminal device to send an SRS are hopped are the same. Consequently, the CSs obtained through hopping overlap with the CSs of the UE that does not support CS hopping, and the sending Petition 870250101444, dated 05 / 11 / 2025, pages 181 / 254 EU SRS 175 / 230, which does not support CS hopping, is affected.

[00423] In this application, a CS range in which the ports used by a terminal device to send an SRS perform CS hopping may consist of at least one set of CSs, and each of the at least one set of CSs does not include CSs of UE ports that do not support CS hopping. Thus, when CSs for hopping are selected from the at least one set of CSs for the ports used by the terminal device to send the SRS, EU port CSs that do not support CS hopping are not selected, to reduce interference. The following describes a reporting method in modalities of this request with reference to Figure 11. As shown in Figure 11, reporting method 900 includes the following steps.

[00424] S910: A terminal device determines, from Q sets of cyclic shift values, a value of NSRS cyclic displacement of each of the corresponding ports NSRS is a first-resource SRS, where a is a positive integer and Q is a positive integer greater than 1 and less than \ or equal to aap. NR

[00425] Optionally, it can be configured by a network device for the terminal device.

[00426] Optionally, the Q sets of cyclic offset values ​​can constitute a set of cyclic offset values ​​that supports CS jumps. More specifically, each NSR of the ports can determine a port cyclic offset value from the set of cyclic offset values ​​that supports CS jumps.

[00427] Optionally, all Q sets of cyclic displacement values ​​include equal quantities of values ​​of Petition 870250101444, dated 05 / 11 / 2025, pages 182 / 254 176 / 230 cyclic shift, and the quantities are all 1. That is, the lengths of all sets of cyclic shift values ​​are equal. Optionally, the network device can send the fourth indication information to the terminal device, and the terminal device can receive the fourth indication information from the network device. Fourth indication information indicates that a number of cyclic displacement values ​​are included in each of the Q u sets of cyclic displacement values Li Li is a positive integer greater than or equal to 1 and less than or equal to a value of cs, max maximum cyclic displacement RS. Alternatively, L1 is greater than or equal to 1 and less than or equal to a cyclic shift value ncs,max / QL maximum RS^. Optionally, 1=1 indicates that the length of each of the Q sets of cyclic shift values ​​is 1. To be specific, each set of cyclic shift values ​​includes a CS. This also indicates that CS hopping is not performed or CS hopping is disabled. L1 must be an integer greater than 1 and Cc cs,max less than RS indicates that there is a set of cyclic displacement values ​​with a length greater than 1. This also indicates that CS jump is performed. When CS jump is performed or CS jump is enabled, method 900 can be performed; otherwise, method 900 cannot be performed.

[00428] In some embodiments, the network device may send indication information to the terminal device to indicate whether CS hopping should be performed, and the terminal device determines, based on the indication information, whether CS hopping should be performed. For example, the indication information may be the number of cyclic offset values ​​included in each set of cyclic offset values, Petition 870250101444, dated 05 / 11 / 2025, pp. 183 / 254 177 / 230 and whether the CS jump should be performed is implicitly indicated by the quantity L1 of cyclic shift values. The quantity L1 of cyclic shift values ​​included in each set of cyclic shift values ​​= 1 indirectly indicates that the CS jump should not be performed. The quantity L1 of cyclic shift values ​​included in each set of cyclic shift values ​​being greater than cs,max and less than RS indirectly indicates that the CS jump should not be performed. NSRS

[00429] Optionally, in some possible implementations, the ports corresponding to a target SRS feature correspond to a set of cyclic offset values ​​that supports CS jumps or a set of cyclic offset values ​​that does not support CS jumps. A quantity of sets of cyclic offset values ​​included in the set of cyclic offset values ​​that supports CS jumps is called the lengthL1 of an area that supports CS jumps. A quantity of sets of cyclic offset values ​​included in the set of cyclic offset values ​​that does not support CS jumps is called the length2 of an area that supports CS jumps and does not support CS jumps. The set of cyclic offset values ​​that supports CS jumps and the set of cyclic offset values ​​that does not support CS jumps are equivalent.To be more specific, a union set of the set of cyclic displacement values ​​that supports jumps from the set of cyclic displacement values ​​that do not include A 1 cs,max JT Tcs,max. 1-1- Λ ' (θ'1,'^5RS 1} L + L — IflSπ Ίsaltos de CS é1.2 SRSFor example, , the set of cyclic displacement values ​​that salto de CS is {θ'1'3'4'6'7'9'10}, the set of values ​​of Petition 870250101444, dated 05 / 11 / 2025, pages 184 / 254 178 / 230 cyclic shift that does not support CS jump is {2'5'8'11}, union set of the set of cyclic shift values ​​that support CS jump and the set of cyclic shift values ​​that do not support CS jump is {0'1'2'3'4'5'6'7'8'9'10'11}. In this embodiment of this application, the set of cyclic shift values ​​that support CS jump is used as an example for description.

[00430] Optionally, the cyclic displacement values ​​included in any two adjacent sets of cyclic displacement values ​​of the Q sets of cyclic displacement values ​​are non-consecutive. To be specific, there is a gap between the values ​​in any two adjacent sets of cyclic displacement values ​​of the Q sets of cyclic displacement values, and the gap is greater than 1. A gap between the values ​​in two adjacent sets of cyclic displacement values ​​can be understood as a difference between the 1st cyclic displacement value in a (k+ 1) The k-th set of cyclic displacement values ​​is the last cyclic displacement value in a k-th set of cyclic displacement values ​​when the cyclic displacement values ​​included in each set of cyclic displacement values ​​are sorted in ascending order of values. Optionally, the intervals Δ between the cyclic displacement values ​​in any two adjacent sets of Q sets are equal. Optionally, that in any two adjacent sets of Q sets are equal can be understood as follows: the intervals between the corresponding cyclic displacement values ​​in any two adjacent sets of cyclic displacement values ​​are equal. For example, the Petition 870250101444, dated 05 / 11 / 2025, pages 185 / 254 179 / 230 The intervals between the values ​​of the first cyclic shift in any two adjacent sets of cyclic shift values ​​are equal. For example, the first set of values ​​of The cyclic displacement is M, the 2nd set of cyclic displacement values ​​is {3, 4}, the 3rd set of cyclic displacement values ​​is ^7, and the 4th set of cyclic displacement values ​​is {9, 10}. In this case, an interval between the 1st set of cyclic displacement values ​​{0, 1} and the 2nd The set of cyclic shift values ​​{3,4} consists of three CSs, an interval between the second set of cyclic shift values ​​{3,4} and the third set of cyclic shift values ​​{6,7} consists of three CSs, and an interval between the third set of cyclic shift values ​​{6,7} and The fourth set of cyclic shift values ​​{9,10} consists of three CSs.

[00431] Optionally, in some embodiments, the cyclic displacement values ​​included in any two adjacent sets of cyclic displacement values ​​of the Q sets of cyclic displacement values ​​may alternatively be consecutive.

[00432] For a definition of intervals between corresponding cyclic offset values ​​in any two adjacent sets of cyclic offset values ​​being equal, see the previous definition of intervals between any two adjacent subsets of comb offset being equal. To avoid repetition, the details are not described.

[00433] Optionally, the cyclic displacement values ​​included in each of the Q sets of cyclic displacement values ​​are consecutive. To be specific, an interval between two adjacent cyclic displacement values ​​in each Petition 870250101444, dated 05 / 11 / 2025, pages 186 / 254 The 180 / 230 set of cyclic displacement values ​​is 1. For example, As shown in the Figure, the cyclic displacement is M, the cyclic displacement is P>4!, the cyclic displacement is {6,7}, and the cyclic displacement is {9,10}. Cyclic displacement in each cyclic cycle is consecutive. Pa 0, the 1st set of values ​​of the 2nd set of values ​​of the 3rd set of values ​​of and the 4th set of values ​​of . In this case, the values ​​of the set of offset values ​​to a definition of adjacent cyclic offset values ​​being consecutive, refer to the previous definition of any two adjacent sets of comb offsets. To avoid repetition, the details are not described.

[00434] Optionally, a CS set that supports CS jumps can be performed on a subset that includes some of the sets of cyclic shift values. In other words, when there are Q sets of cyclic shift values, the CS jump can be performed on a subset that includes some of the Q sets of cyclic shift values.

[00435] Optionally, the Q sets of cyclic offset values ​​can be specified in a protocol or configured by the network device.

[00436] Optionally, a qth set of cyclic displacement values ​​from the Q sets of cyclic displacement values ​​is obtained based on at least one initial cyclic displacement value CS, a range of cyclic displacement values ​​Δ between any two adjacent sets of cyclic displacement values, a quantity of comb displacements included in the qth set of cyclic displacement values, or the maximum cyclic displacement value. Petition 870250101444, dated 05 / 11 / 2025, pages 187 / 254 181 / 230 cs, max nRS In other words, the terminal device can determine the qth set of cyclic displacement values ​​based on at least one initial cyclic displacement value CS, the range of cyclic displacement values ​​Δ between any two adjacent sets of cyclic displacement values, the number of comb displacements included in the qth set of cyclic displacement values, or the maximum cyclic displacement value Hrs, wherein the ranges of cyclic displacement values ​​between any two adjacent sets of cyclic displacement values ​​are all positive integers ranging from 1 to n, and an initial cyclic displacement value corresponding to each of the sets of cyclic displacement values ​​CS. To be specific, optionally, the network device can specify at least one of the initial cyclic offset value CS, the range of cyclic offset values ​​Δ between any two sets of adjacent cyclic offset values, or C cs ,max the maximum cyclic offset valueRS for the terminal device. Optionally, the initial cyclic offset value start nCS may be indicated by the network device or specified in the protocol, or it may be determined based on a start parameter configured by the network device. For example, CS may be nC4SRS determined according to formula (6). Optionally, a qth set of cyclic offset values ​​is obtained based on at least one deq, an initial cyclic offset value startCS, a range of cyclic offset values ​​Δ Petition 870250101444, dated 05 / 11 / 2025, pages 188 / 254 182 / 230 between any two sets of adjacent cyclic displacement values ​​or the maximum cyclic displacement value cs, max n RS. Optionally, the qth set of cyclic displacement values ​​((n+ (q -1)Δ)mod nCSm, (nstart + (q -1)Δ + 1)mod nC,---,(+ (q - 1)Δ + L -1!mod nC'max ) I \ CS XJ x J SRS ' \ CS x J 7 j SRS ' '1 CS \ 1 / 1 / SRS I , where mod() is a modulo operation. For example, as shown in cs,max Figure 8, nRS is 12, startCS is 0, Δ is 3 and the length L a1do qésimo conjunto de valores de mobilidade cyclic é 2. In this case, the 1st (q=1) set of comb displacements is {0, 1}, the 2nd (q=2) set of comb displacements is {3, 4}, the The 3rd (q=3) set of comb displacements is {6,7}, and the 4th (q=4) set of comb displacements is {9,10}. Optionally, the range of cyclic displacement values ​​Δ between any two adjacent sets of cyclic displacement values ​​is related to a cs,max quantity of maximum cyclic displacements and to the quantity Q is a set of cyclic displacements. "CS, max" A _ nSRS For example, Q For example, in cs, max Figure 10, SRSé 12. As the EU does not support jumping CS occupies four CSs, and the four Since CSs are equally spaced, the quantity Q of sets of cyclic displacements can be 4. Therefore, the terminal device can determine that Δ 3. In some modes, the network device may directly indicate Δ; or the network device may indicate SRSQ, and the terminal device determines, with SRS based on cs,max, that Δ is 3.

[00437] Optionally, the terminal device can determine a cyclic offset value of a reference port between Petition 870250101444, dated 05 / 11 / 2025, pp. 189 / 254 183 / 230 NSRS Q asapportas de um dos conjuntos de valores de mobilidade cíclico, e o Dispositivo Terminação pode determina NSRS is a cyclic offset value of another port among the ports based on the cyclic offset value of the reference port. For example, the reference port could be the 1aNSR port of the ports, and the 1a port could be understood as a port with the lowest CS. For example, as shown in Figure 10, the 1st set of cyclic shift values ​​is {0,1}, the 2nd set of cyclic shift values ​​is {3,4}, the 3rd set of cyclic shift values ​​is {6,7}, the 4th set of cyclic shift values ​​is {9,10}, and the reference gate is gate 2. For example, it is determined that a cyclic shift value of gate 2 is a CS 1. Since two adjacent gates are spaced by three CSs, it can be determined that a cyclic shift value of gate 3 is a CS 4, a cyclic shift value of gate 0 is a CS 7, and a cyclic shift value of gate 1 is a CS 10.

[00438] Optionally, the variations in the cyclic NSRS offset values ​​of all ports (the variation can also be called the step relative to a reference cyclic offset value for each port) can be the same. For example, if port 1 jumps from a first cyclic offset value to a second cyclic offset value and port 2 jumps from a third cyclic offset value to a fourth cyclic offset value, a range of cyclic offset values ​​1 is the same as a range of cyclic offset values ​​2, where the range of cyclic offset values ​​1 is a range of cyclic offset values ​​between the second cyclic offset value and the first cyclic offset value, and the range of cyclic offset values Petition 870250101444, dated 05 / 11 / 2025, pages 190 / 254 184 / 230 cyclic 2 is a range of cyclic offset values ​​between the fourth cyclic offset value and the third cyclic offset value. For example, as shown in Figure 10, a reference cyclic offset value for port 2 is CS 0, a reference cyclic offset value for port 3 is CS 3, a reference cyclic offset value for port 0 is CS 6, and a reference cyclic offset value for port 1 is CS 9. If a variation of the cyclic offset value for port 2 is 1, port 2 needs to jump from CS 0 to CS 1, port 3 needs to jump from CS 3 to CS 4, port 0 needs to jump from CS 6 to CS 7, and port 1 needs to jump from CS 9 to CS 10.

[00442] In formula (10), nSRS(1)f(nSRS), a value of b is 0 or 1, f(nSRS) is a value generated based on a random sequence. A range of values ​​of f (nSRs) - [0, QL. — 1] .

For a definition of SRS, see the descriptions in the previous embodiments.

[00447] For example, as shown in Figure 12 (a) to Figure (h), optionally, Q=4. The four sets of cyclic displacement values ​​are {0,1} {3,4} {6,7} and {9,10} The four sets of cyclic shift values ​​can constitute a set of cyclic shift values ​​{0, 1, 3, 4, 6, 7, 9, 10} that supports CS jump. One cyclic shift value from each of the four gates, that is, one gate 0, one door 1, one door 2 and one door 3, the terminal device can be determined from {0,1,3,4,6,7,9,10} and the values ​​of Petition 870250101444, dated 05 / 11 / 2025, pp. 193 / 254 187 / 230 cyclic offset of all ports can be the same. For example, Figure 12 (a) shows the reference cyclic offset values ​​of the four ports. In case 1, the reference cyclic offset values ​​of the four ports are calculated according to formula (6). In case 2, the reference cyclic offset values ​​of the four ports can be indicated by the network device or predefined in the protocol; or the network device indicates reference cyclic offset values ​​of some of the ports, and the terminal device can obtain reference cyclic offset values ​​of other ports based on the reference cyclic offset values ​​of some of the ports.A reference cyclic offset value of port 2 is a CS 0, a reference cyclic offset value of port 3 is a CS 3, a reference cyclic offset value of port 0 is a CS 6, and a reference cyclic offset value of port 1 is a CS 9. During an SRS transmission time, a CS of each port varies by 1. As shown in Figure 12(b), the CSs of port 2, port 3, port 0, and port 1 are a CS 1, a CS 4, a CS 7, and a CS 10, respectively. During another SRS transmission, a CS for each port varies by 2. As shown in Figure 12(c), the CSs for port 2, port 3, port 0, and port 1 are, respectively, CS 3, CS 6, CS 9, and CS 0. During the second SRS transmission, the CS for each port varies by 2. As shown in Figure 12(c), the CSs for port 2, port 3, port 0, and port 1 are, respectively, CS 3, CS 6, CS 9, and CS 0. During another SRS transmission, the CS for each port varies by 1.As shown in Figure 12(d), the CSs of port 2, port 3, port 0, and port 1 are, respectively, CS 4, CS 7, CS 10, and CS 1. During another SRS transmission, the CS of each port varies by 2. As shown in Figure 12(e), the CSs of port 2, port 3, port 0, and port 1 are CS 6, CS 9, CS 0, and CS 3, respectively. During another SRS transmission time,... Petition 870250101444, dated 05 / 11 / 2025, pages 194 / 254 188 / 230 one CS of each port varies by 1. As shown in Figure 12(f), the CSs of port 2, port 3, port 0 and port 1 are CS 7, CS 10, CS 1 and CS 4, respectively. During another SRS transmission time, one CS of each port varies by 2. As shown in Figure 12(g), the CSs of port 2, port 3, port 0 and port 1 are CS 9, CS 0, CS 3 and CS 6, respectively. During another SRS transmission time, one CS of each port varies by 2. As shown in Figure 12(h), the CSs of port 2, port 3, port 0 and port 1 are CS 10, CS 1, CS 4 and CS 7, respectively. It can be understood that all Figures 12(a) to Figure 12(h) correspond to different f(nSRS) basis. Alternatively, the terminal device selects, in one of the ways shown in Figure 12(a) to Figure 12(h), to send an SRS.

[00448] In the two previous cases, the maximum displacement value The maximum comb offset (cs,max) can be fixed. In some cases, the maximum comb offset (cs,max) can be K times SRS, the maximum value of cs,max nSRS, where K is a positive integer. In this case, there are a total of nSRS offset values. To be specific, they are divided into smaller granularities. In this case, the CSs is the number of cyclic displacement values ​​included in each cs, max.

[00460] The way the network device determines, from the Q sets of cyclic shift values, the value of The NR cyclic offset of each of the ports corresponding to the first SRS resource is the same as the way the terminal device determines, from the Q sets of cyclic offset values, the NR cyclic offset value of each of the ports corresponding to the first SRS resource. Therefore, the cyclic offset value of each port determined by the network device is the same as the cyclic offset value of each port determined by the terminal device, so that an SRS can be sent and received correctly. To avoid repetition, the detailed description of how the network device determines, from the Q sets of cyclic offset values, the value of NR cyclic displacement of each of the ports corresponding to the first SRS resource is not performed in S920.

[00461] It should be noted that a sequence of S910 and S920 is not Petition 870250101444, dated 05 / 11 / 2025, pp. 199 / 254 193 / 230 limited, and S910 can be performed before, after, or simultaneously with S920.

[00462] S930: The terminal device sends an SRS based on NSRS is the cyclic offset value of each of the ports, and the network device receives the SRS based on the NR cyclic offset value of each of the ports.

[00463] In the previous method, the terminal device and the network device can determine, from the Q sets of cyclic offset values, the cyclic NR offset value of each of the ports corresponding to the first SRS resource. Since any two Q sets of cyclic shift values ​​are non-consecutive, the overlap with a EU CS that does not support CS hopping can be avoided, reducing interference.

[00464] In the previous method 900, Q sets of cyclic offset values ​​correspond to Q subsets of cyclic offset bias values. Optionally, the Q subsets of cyclic offset bias values ​​constitute a first set of cyclic offset bias values. To be more specific, the terminal device can determine a cyclic offset bias value from the first set of cyclic offset NSR bias values ​​based on each of the ports corresponding to the first SRS feature, and the terminal device can determine the cyclic offset value of each port based on the cyclic offset bias value of each port and an initial cyclic offset bias value of each port, and send the SRS based on the cyclic offset value of each port. That is, the terminal device can send the SRS based on a cyclic offset. Petition 870250101444, dated 05 / 11 / 2025, pp. 200 / 254 194 / 230 in the Qsets of cyclic offset values, or it can send the SRS based on the Qsubsets of cyclic offset bias values; or the terminal device can determine the Qsets of cyclic offset values ​​based on the initial cyclic offset value of each port and the subsets of cyclic offset bias values, and send the SRS based on the Qsets of cyclic offset values. For example, as NSRS = 4 shown in Figure 13,ap, and the four ports are port 0, port 1, port 2, and port 3. The network device can configure a length of the first set of cyclic offset bias values ​​as follows: and configure the maximum comb offset value as follows: CS,max i nSRS =12 A subset of shift bias values ​​is {0, 1}, and a first set of cyclic shift bias values ​​including the subset of cyclic shift bias values ​​is also {0, 1}. n'1= 0 An initial cyclic offset value of gate 0 is SRS, and a set of cyclic offset values ​​corresponding to gate 0 can be {0, 1}. An initial cyclic offset value nCS,1=3 of gate 1 is SRS, and a set of cyclic offset values ​​corresponding to gate 1 can be {3, 4}. An initial cyclic offset value of ΛCS, irn,= 6 of gate 2 is SRS, and a set of cyclic offset values ​​corresponding to gate 1 can be {6, 7}. An initial cyclic offset value of gate 3 nCS,1= 9 is SRS, and a set of cyclic offset values ​​corresponding to gate 3 can be {9, 10}.

Optionally, in this type of request, nCS, iSRS can be St start, i reservado porcS.
