[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] Figure 1 A block diagram of a communication system provided in an exemplary embodiment of the present disclosure is shown. The communication system may include an access network 12 and a user terminal 14.

[0048] Access network 12 includes a plurality of network devices 120. Network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functionality to user terminal (hereinafter referred to as "terminal") 14. Base stations may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functionality may differ; for example, in Long Term Evolution (LTE) systems, they are called eNodeB or eNB; in 5G NR (New Radio) systems, they are called gNodeB or gNB. As communication technologies evolve, the description of "base station" may change. For the convenience of the description in the embodiments of this disclosure, the devices that provide wireless communication functionality to user terminal 14 are collectively referred to as network devices.

[0049] User terminal 14 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile stations (MS), terminal devices, etc. For ease of description, the devices mentioned above are collectively referred to as user terminals. Network device 120 and user terminal 14 communicate with each other through some air interface technology, such as a Uu interface.

[0050] For example, there are two communication scenarios between network device 120 and user terminal 14: uplink communication scenario and downlink communication scenario. Uplink communication refers to sending signals to network device 120; downlink communication refers to sending signals to user terminal 14.

[0051] The technical solutions of this disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution of NR system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, and Wireless Local Area Network (WLAN). Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems.

[0052] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-everything (V2X) systems. The embodiments disclosed herein can also be applied to these communication systems.

[0053] Figure 2A flowchart illustrating a method for transmitting SRS according to an exemplary embodiment of this disclosure is shown, the method being applied to Figure 1 In the terminal of the communication system shown, the method includes:

[0054] Step 210: Receive the configuration information of the SRS resources, which include 8 antenna ports.

[0055] For example, the terminal receives configuration information of an SRS resource sent by the network device. The configuration information is used to configure an SRS resource for the terminal.

[0056] The configured SRS resources include 8 antenna ports. That is, the SRS resource configuration information includes: the number of SRS antenna ports. Port number P of the 8 antenna ports i =1000+i,i∈{0,1,2,3,4,5,6,7}.

[0057] Alternatively, the configured SRS resources include at least two antenna port groups corresponding to 8 antenna ports (i.e., K antenna port groups). In other words, the SRS resource configuration information includes: the number of SRS antenna ports. The number of antenna ports in each antenna port group is 8 / K, where K = 2, 4, or 8; the port number P of the 8 antenna ports is... i =1000+i, where i∈{0,1,2,3,4,5,6,7}. Alternatively, the SRS resource configuration information may also include: the number of SRS antenna ports. The number of antenna ports in each antenna port group is 8 / K, where K = 2, 4, or 8; the port numbers of the 8 / K antenna ports in each antenna port group.

[0058] Step 220: Map the SRS corresponding to at least two antenna port groups onto the physical resources corresponding to different transmission combs, and simultaneously send the SRS corresponding to at least two antenna port groups. The at least two antenna port groups are obtained based on the division of 8 antenna ports.

[0059] When measuring uplink channel quality, the terminal maps an SRS resource onto the same physical resource (PR). For example, physical resources refer to continuous carrier resources in the frequency domain, where one physical resource block (PRB) corresponds to 12 consecutive carriers in the frequency domain and one timeslot in the time domain.

[0060] For example, the uplink channel includes at least one of: Physical Uplink Control Channel (PUCCH); Physical Uplink Shared Channel (PUSCH). The terminal may map an SRS resource on the physical resources of PUCCH and / or PUSCH.

[0061] For example, the terminal maps an SRS resource on the same physical resource based on the configuration information.

[0062] The above configuration information includes at least one of the following parameters:

[0063] Transmission comb parameter K TC ;

[0064] Frequency domain offset parameter

[0065] SRS configuration bandwidth;

[0066] Circular shift parameter

[0067] Number of antenna ports

[0068] The temporal location of the transport comb.

[0069] The transmission comb parameter indicates the comb-like structure of the SRS resources in the frequency domain, meaning that the SRS resources are not mapped onto consecutive subcarriers. The transmission comb parameter is denoted by `comb`, where `comb = K`. TC K TC The value is a positive integer, and the interval between adjacent subcarriers in the SRS resource is (K). TC -1) subcarriers, that is, the interval (K) between adjacent resource elements (REs) in the SRS resource. TC -1) subcarriers, for example, when comb=8, adjacent RE resources in an SRS resource are spaced 7 subcarriers apart. The frequency offset parameter refers to the offset value of the subcarrier occupied by the first RE resource in an SRS resource; the frequency offset parameter is a non-negative integer less than the transmission comb parameter. The SRS configuration bandwidth refers to the bandwidth occupied by the SRS resource. The cyclic shift parameter refers to the number of bits cyclically shifted in the sequence. An antenna port is a logical transmit channel defined by a reference signal; the antenna port is mapped to a physical antenna for signal transmission. The time-domain position of the transmission comb indicates the symbols occupied by the transmission comb in the time slot.

[0070] For example, the above configuration information may also include: the length of the ZC sequence; the length of the ZC sequence refers to the numerical length of the ZC sequence. For instance, the terminal generates 8 SRS sequences based on at least one ZC sequence, and uses the 8 SRS sequences to carry the SRS of 8 antenna ports.

[0071] For example, each antenna port group corresponds to one transmission comb. The terminal maps the SRS corresponding to at least two antenna port groups to the physical resources corresponding to at least two transmission combs, and simultaneously transmits the SRS corresponding to at least two antenna port groups.

[0072] For example, the aforementioned at least two antenna port groups may be antenna port groups mapped to the same antenna panel or different antenna panels; that is, the aforementioned at least two antenna ports are antenna port groups mapped to M antenna panels, where M is a positive integer less than or equal to 8. For instance, the first antenna port group in the aforementioned at least two antenna port groups is mapped to the first antenna panel, and the second antenna port group in the aforementioned at least two antenna port groups is mapped to the second antenna panel.

[0073] For example, a terminal may use N consecutive orthogonal frequency-division multiplexing (OFDM) symbols for one SRS resource, where N = {1, 2, 4}.

[0074] For example, the SRS resource described above has at least one of the following functions:

[0075] codebook;

[0076] Antenna switching;

[0077] Non-codebook.

[0078] The terminal can perform channel quality detection based on the codebook, channel quality detection during antenna switching, or channel quality detection based on a non-codebook.

[0079] For example, the transmission comb parameter K TC The value range of K is {2, 4, 8, 12}. For example, with K... TCTaking a parameter of 2 as an example, when the transmission comb parameter is equal to 2, the terminal maps two transmission combs on one PRB: a first transmission comb 301 and a second transmission comb 302; the frequency domain offset parameter of the first transmission comb 301 is 0, and the frequency domain offset parameter of the second transmission comb 302 is 1; adjacent subcarriers in each transmission comb are spaced by 1 subcarrier, the subcarriers occupied by the first transmission comb 301 include subcarrier 0, subcarrier 2, subcarrier 4, subcarrier 6, subcarrier 8, and subcarrier 10, and the subcarriers occupied by the second transmission comb 302 include subcarrier 1, subcarrier 3, subcarrier 5, subcarrier 7, subcarrier 9, and subcarrier 11; both the first transmission comb 301 and the second transmission comb 302 are located on symbol 10 of one time slot; the four antenna ports, port 0, port 1, port 2, and port 3, are mapped to the first transmission comb 301, and the four antenna ports, port 4, port 5, port 6, and port 7, are mapped to the second transmission comb 302. For example, Figure 3 Each of the two transport combs in the middle can occupy 1 OFDM symbol.

[0080] For example, the maximum value of the cyclic shift parameter of the transmission comb corresponding to at least two antenna port groups is Cyclic shift parameters configured for 8 antenna ports The corresponding value range is

[0081] Optionally, the maximum number of cyclic shift parameters supported by the transport comb parameters is 8. The range of values ​​is The terminal then uses all eight cyclic shift parameters to generate SRS resources.

[0082] For example, the maximum number of cyclic shift parameters supported by the transport comb parameters is 12. The range of values ​​is The terminal uses a portion of the 12 cyclic shift parameters to generate SRS resources, meaning it actually uses 8 out of the 12 cyclic shift parameters to generate SRS resources.

[0083] For example, the above configuration information includes a cyclic shift parameter corresponding to at least two antenna port groups; after receiving the configuration information, the terminal calculates the cyclic shift parameter corresponding to all antenna ports in at least two antenna port groups based on the configured cyclic shift parameter.

[0084] Alternatively, the above configuration information may include a cyclic shift parameter corresponding to each of the at least two antenna port groups; after receiving the configuration information, the terminal calculates the cyclic shift parameter corresponding to all ports within the antenna port group for each antenna port group using the cyclic shift parameter configured for the antenna port group.

[0085] Among them, the cyclic shift parameter The calculation formula is as follows:

[0086]

[0087] Circular offset value α of circular shift i The calculation formula is as follows:

[0088]

[0089] In the formula, i is a positive integer; in the formula This indicates the configured cyclic shift parameters.

[0090] In other embodiments, the transmission comb parameter K TC When the bandwidth is equal to 8 or 12, only one SRS resource can be mapped to one PRB. Therefore, the minimum bandwidth parameter corresponding to the SRS configuration bandwidth must be greater than or equal to the bandwidth of 6 PRBs; or, the SRS configuration bandwidth must be a multiple of the bandwidth of 6 PRBs; or, the minimum bandwidth parameter corresponding to the SRS configuration bandwidth must be greater than or equal to the bandwidth of 8 PRBs; or, the SRS configuration bandwidth must be a multiple of the bandwidth of 8 PRBs. This allows multiple RE resources to be mapped to multiple PRBs, avoiding the unrepresentative nature of uplink channel quality measurements due to a limited number of RE resources.

[0091] In summary, the SRS transmission method provided in this embodiment allows the eight antenna ports in the SRS resource to be divided into at least two antenna port groups. After receiving the configuration information of the SRS resource, the terminal maps the SRS corresponding to the at least two antenna port groups onto the physical resources corresponding to different transmission combs, and simultaneously transmits the SRS corresponding to the at least two antenna port groups. This method is used to support the implementation of related functions when the terminal uses eight transmit antenna ports, such as supporting codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or supporting non-codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or supporting channel quality detection during antenna switching when the terminal uses eight transmit antenna ports.

[0092] In some embodiments, at least two antenna port groups can be mapped to at least two transmission combs with different frequency domain offset parameters, such as... Figure 4 As mentioned above, step 220 can be implemented by step 420 as follows:

[0093] Step 420: Map the SRS corresponding to at least two antenna port groups onto the physical resources corresponding to at least two transmission combs in the frequency domain dimension, and simultaneously transmit the SRS corresponding to at least two antenna port groups.

[0094] There is a one-to-one correspondence between the aforementioned antenna port groups and transmission combs. Optionally, at least two antenna port groups correspond to transmission combs in the same time domain location. For example, Figure 3 The first transmission comb 301 and the second transmission comb 302 are both located on time slot symbol 10.

[0095] Optionally, the transmission comb parameter K of the transmission comb corresponding to at least two antenna port groups TC Same. For example, Figure 3 The transfer comb parameters of the first transfer comb 301 and the second transfer comb 302 are both 2.

[0096] Optionally, the frequency domain offset parameters of the transmission combs corresponding to at least two antenna port groups. Different, the stated The value is less than K TC The non-negative integer. For example, if the value of the transmission comb parameter is 8, then the range of the frequency domain offset parameter of the transmission comb corresponding to at least two antenna port groups is {0,1,2,3,4,5,6,7}.

[0097] Optionally, some or all of the frequency domain offset parameters of the aforementioned transmission comb are configured by the network device for the terminal. For example, the terminal receives the first frequency domain offset parameter of the transmission comb corresponding to the first antenna port group, where the first antenna port group is one of at least two antenna port groups; based on the first frequency domain offset parameter, it calculates other frequency domain offset parameters of the transmission combs corresponding to other antenna port groups, where the other antenna port groups are antenna port groups other than the first antenna port group among the at least two antenna port groups.

[0098] Alternatively, the terminal receives frequency domain offset parameters of the transmission comb corresponding to at least two antenna port groups.

[0099] That is, the network device configures a frequency domain offset parameter of the transmission comb for the terminal. Then, based on this frequency offset parameter, other frequency offset parameters of other transmission combs are calculated. Alternatively, the network device can configure a set of frequency domain offset parameters corresponding to at least two transmission combs for the terminal.

[0100] Optionally, the terminal calculates the other frequency domain offset parameters based on the adjacent transmission comb principle; or, based on the uniform distribution principle; or, based on the maximum spacing principle; or, based on other predefined principles. For example, the principles for determining the above four other frequency domain offset parameters are explained:

[0101] 1) Adjacent transport comb principle.

[0102] Frequency domain offset parameters for each port of other transmission combs Generate according to the following formula:

[0103]

[0104] or,

[0105]

[0106] For example, such as Figure 3 As shown, the corresponding subcarriers on the first transmission comb 301 and the second transmission comb 302 are adjacent to each other.

[0107] 2) The principle of uniform distribution.

[0108] Frequency domain offset parameters for each port of other transmission combs Generate according to the following formula:

[0109]

[0110] For example, such as Figure 5 As shown, the K values ​​of the third transmission comb 501 and the fourth transmission comb 502 in the SRS resource are... TC =4, where the frequency domain offset parameter of the third transmission comb 501 is 3 and the frequency domain offset parameter of the fourth transmission comb 502 is 1; both the third transmission comb 501 and the fourth transmission comb 502 occupy time slot symbols 12 and 13; adjacent subcarriers in each transmission comb are spaced 3 subcarriers apart, the subcarriers occupied by the third transmission comb 501 include subcarrier 1, subcarrier 5, and subcarrier 9, and the subcarriers occupied by the fourth transmission comb 502 include subcarrier 3, subcarrier 7, and subcarrier 11; in the 6 subcarriers corresponding to the two transmission combs, adjacent subcarriers are spaced 1 subcarrier apart, that is, the two transmission combs conform to the principle of uniform distribution.

[0111] 3) Maximum interval principle.

[0112] The difference in frequency domain offset parameters between connected transmission combs is the largest. For example, K TC When the value is 4, the first frequency domain offset parameter is 0, and the other frequency domain offset parameters are 3, so that at least two transmission combs meet the maximum spacing principle.

[0113] For example, such as Figure 6 As shown, the K values ​​of the fifth transmission comb 601 and the sixth transmission comb 602 in the SRS resource... TC=8, where the frequency domain offset parameter of the fifth transmission comb 601 is 0, and the frequency domain offset parameter of the sixth transmission comb 602 is 1; both the fifth transmission comb 601 and the sixth transmission comb 602 occupy 4 consecutive time slot symbols 8 to 11; the adjacent subcarriers in each transmission comb are spaced 7 subcarriers apart, the subcarriers occupied by the fifth transmission comb 601 include subcarriers 0 and 8 of the first PRB, and subcarrier 4 of the second PRB, and the subcarriers occupied by the sixth transmission comb 602 include subcarrier 7 of the first PRB, and subcarriers 3 and 11 of the second PRB; in the 6 subcarriers corresponding to the two transmission combs, the subcarriers corresponding to each other are spaced 6 subcarriers apart, that is, the two transmission combs meet the maximum spacing principle.

[0114] 4) Other predefined principles.

[0115] Other predefined principles can be other ways of determining other frequency domain offset parameters as defined by the protocol.

[0116] In summary, the SRS transmission method provided in this embodiment supports SRS transmission on multiple transmission combs in different frequency domain dimensions for multiple antenna port groups.

[0117] In some embodiments, at least two antenna port groups can be mapped to at least two transmission combs with the same frequency domain offset parameter, such as... Figure 7 As mentioned above, step 220 can be implemented by step 720 as follows:

[0118] Step 720: Map the SRS corresponding to at least two antenna port groups onto the physical resources corresponding to at least two transport combs in the time domain dimension, and simultaneously transmit the SRS corresponding to at least two antenna port groups.

[0119] There is a one-to-one correspondence between the antenna port groups and the transmission combs. Optionally, at least two antenna port groups correspond to transmission combs that are located in different time domains but are adjacent to each other.

[0120] Optionally, the transmission comb parameter K of the transmission comb corresponding to at least two antenna port groups TC same.

[0121] Optionally, the frequency domain offset parameters of the transmission combs corresponding to at least two antenna port groups. same, The value is less than K TC The non-negative integer. For example, if the value of the transmission comb parameter is 8, then the range of the frequency domain offset parameter of the transmission comb corresponding to at least two antenna port groups is {0,1,2,3,4,5,6,7}.

[0122] For example, such as Figure 8As shown, the SRS resource is configured with a seventh transmission comb 801 and an eighth transmission comb 802; the transmission comb parameters of the seventh transmission comb 801 and the eighth transmission comb 802 are both 8, and the frequency domain offset parameter is both 7; the seventh transmission comb 801 and the eighth transmission comb 802 are located on the same subcarriers, including: subcarrier 7 on the first PRB, and subcarriers 3 and 11 on the second PRB; the seventh transmission comb 801 and the eighth transmission comb 802 are located at different time domain positions, the seventh transmission comb 801 is located on time slot symbols 8 and 9, and the eighth transmission comb 802 is located on time slot symbols 10 and 11, and the time domain positions of the seventh transmission comb 801 and the eighth transmission comb 802 are adjacent.

[0123] For example, the time-domain locations of at least two transport combs can be in the same time slot or in different time slots. For instance, Figure 8 The seventh transmission comb 801 and the eighth transmission comb 802 are located in the same time slot.

[0124] Optionally, the frequency domain offset parameter of the transmission comb corresponding to at least two antenna port groups is configured by the network device for the terminal. For example, the terminal receives a frequency domain offset parameter of the transmission comb corresponding to at least two antenna port groups; that is, the network device configures a frequency domain offset parameter of the transmission comb for the terminal.

[0125] In summary, the SRS transmission method provided in this embodiment supports SRS transmission on multiple transmission combs in different time domain dimensions for multiple antenna port groups.

[0126] In some embodiments, at least two antenna port groups are obtained by sequentially grouping eight antenna ports according to their port numbers. For example... Figure 3 As shown, one antenna port group includes port 0, port 1, port 2 and port 3, and another antenna port group includes port 4, port 5, port 6 and port 7.

[0127] In other embodiments, at least two antenna port groups are obtained by grouping the eight antenna ports according to their port numbers (odd or even). For example... Figure 5 As shown, one antenna port group includes port 0, port 2, port 4 and port 6, and another antenna port group includes port 1, port 3, port 5 and port 7.

[0128] In other embodiments, at least two antenna port groups are obtained by sequentially grouping the odd-numbered port numbers out of the eight antenna ports to obtain at least two first antenna port groups, and by sequentially grouping the even-numbered port numbers out of the eight antenna ports to obtain at least two second antenna port groups. For example... Figure 9As shown, after grouping the 8 antenna ports in the frequency domain, one first antenna port group includes port 1 and port 3, and another first antenna port group includes port 5 and port 7; one second antenna port group includes port 0 and port 2, and another second antenna port group includes port 4 and port 6. For example, the transmission comb parameter configured in the SRS resource is 12, and the frequency domain offset parameters of the transmission comb include {5, 7, 9, 11}. Therefore, there are 4 transmission combs with the same transmission comb structure.

[0129] like Figure 10 As shown, the ports with even numbers among the 8 antenna ports are: port 0, port 2, port 4, and port 6; the ports with odd numbers among the 8 antenna ports are: port 1, port 3, port 5, and port 7; after grouping the 8 antenna ports in the time domain, one first antenna port group includes port 1 and port 3, and another first antenna port group includes port 5 and port 7; one second antenna port group includes port 0 and port 2, and another second antenna port group includes port 4 and port 6.

[0130] In other embodiments, at least two antenna port groups are grouped according to a predefined combination method in the protocol. For example, ports 0, 1, 6, and 7 are predefined as one antenna port group, while ports 2, 3, 4, and 5 are another antenna port group.

[0131] In summary, the SRS transmission method provided in this embodiment supports multiple ports combined on multiple transport combs for SRS transmission.

[0132] Figure 11 A flowchart illustrating a method for receiving SRS provided in an exemplary embodiment of this disclosure is shown, the method being applied to Figure 1 In the network device of the communication system shown, the method includes:

[0133] Step 1010: Send the configuration information of the SRS resources, which include 8 antenna ports.

[0134] The network device configures and sends SRS resource configuration information to the terminal.

[0135] When at least two transmission combs configured in the SRS resource configuration information are in different frequency domain dimensions, the SRS resource configuration information includes at least one of the following:

[0136] A time-domain location of the transmission comb corresponding to at least two antenna port groups;

[0137] At least two antenna port groups correspond to a transmission comb parameter K TC ;

[0138] A frequency domain offset parameter of the transmission comb corresponding to the first antenna port group in at least two antenna port groups, wherein the first antenna port group is one of at least two antenna port groups; or, frequency domain offset parameters of at least two transmission combs corresponding to at least two antenna port groups.

[0139] A cyclic shift parameter corresponding to at least two antenna port groups; or, a cyclic shift parameter corresponding to each of the at least two antenna port groups.

[0140] When at least two transport combs configured in the SRS resource configuration information are in different time domain dimensions, the SRS resource configuration information includes at least one of the following:

[0141] At least two adjacent time-domain positions of the transmission comb corresponding to at least two antenna port groups;

[0142] At least two antenna port groups correspond to a transmission comb parameter K TC ;

[0143] A frequency domain offset parameter corresponding to at least two antenna port groups;

[0144] A cyclic shift parameter corresponding to at least two antenna port groups; or, a cyclic shift parameter corresponding to each of the at least two antenna port groups.

[0145] When a cyclic shift parameter is configured for at least two antenna port groups, the cyclic shift parameter is used to determine the cyclic shift parameter of all antenna ports in the at least two antenna port groups; when a cyclic shift parameter is configured for each antenna port group, the cyclic shift parameter corresponding to an antenna port group is used to determine the cyclic shift parameter of all antenna ports within that antenna port group.

[0146] Optionally, at least two antenna port groups are obtained by sequentially grouping the eight antenna ports according to their port numbers; or, at least two antenna port groups are obtained by grouping the eight antenna ports according to their port numbers in an odd-even manner; or, at least two antenna port groups are obtained by grouping the odd-numbered port numbers among the eight antenna ports sequentially to obtain at least two first antenna port groups, and by sequentially grouping the even-numbered port numbers among the eight antenna ports to obtain at least two second antenna port groups.

[0147] For example, the number of antenna ports of the SRS Port number P of the 8 antenna ports i =1000+i,i∈{0,1,2,3,4,5,6,7}.

[0148] Optionally, the configuration information for the SRS resources also includes: the maximum value of the cyclic shift parameter of the transmission comb corresponding to at least two antenna port groups is... Cyclic shift parameters configured for 8 antenna ports The corresponding value range is

[0149] For example, the maximum number of cyclic shift parameters supported by the transport comb parameters is 8. The range of values ​​is The terminal then uses all eight cyclic shift parameters to generate SRS resources.

[0150] For example, the maximum number of cyclic shift parameters supported by the transport comb parameters is 12. The range of values ​​is The terminal uses a portion of the 12 cyclic shift parameters to generate SRS resources, meaning it actually uses 8 out of the 12 cyclic shift parameters to generate SRS resources.

[0151] For example, the SRS resource can function as one of the following: codebook; antenna switching; or non-codebook.

[0152] For example, network devices can send SRS allocation information to terminals via higher-level signaling.

[0153] Step 1020: Simultaneously receive SRS corresponding to at least two antenna port groups on physical resources corresponding to different transmission combs. The at least two antenna port groups are obtained based on the division of 8 antenna ports.

[0154] Optionally, the terminal may simultaneously receive SRS corresponding to at least two antenna port groups on physical resources corresponding to transmission combs in different frequency domain dimensions; or, it may simultaneously receive SRS corresponding to at least two antenna port groups on physical resources corresponding to transmission combs in different time domain dimensions.

[0155] In summary, the SRS receiving method provided in this embodiment divides the eight antenna ports in the SRS resource into at least two antenna port groups. After the network device sends the configuration information of the SRS resource to the terminal, it simultaneously receives the SRS corresponding to at least two antenna port groups on the physical resources corresponding to different transmission combs. This method is used to support the implementation of related functions when the terminal uses eight transmit antenna ports. For example, it is used to support codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or to support non-codebook-based channel quality detection when the terminal uses eight transmit antenna ports, or to support channel quality detection during antenna switching when the terminal uses eight transmit antenna ports.
