[0149] FIG1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0152] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces within the network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0153] In some embodiments, the network device 102 can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0154] In some embodiments, the network device 102 may be a single device, or may be multiple devices or a group of devices. The network device 102 may be virtual or physical.

[0155] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0156] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0157] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0158] In a communication system, a terminal can send an SRS to an access network device to obtain uplink channel quality. The SRS resources used by the terminal to send the SRS can be configured by the access network device. The access network device can send configuration information to the terminal to configure the SRS resources.

[0159] A terminal may have one or more antenna ports, and may transmit SRS via one or more antenna ports. In this case, the SRS resources configured by the access network device for the terminal may correspond to the number of antenna ports of the terminal. More specifically, an SRS resource may have one or more SRS ports, and the number of SRS ports may correspond to the number of antenna ports of the terminal. In some embodiments, the number of SRS ports supported by an SRS resource may be 1, 2, 4, 8, etc. In some embodiments, the number of SRS ports may be configured using the high-level parameter nrofSRS-Ports in the configuration information.

[0160] The SRS resource may occupy one or more symbols in the time domain (e.g., orthogonal frequency division multiplexing (OFDM) symbols). The symbols occupied by the SRS resource may be continuous in the time domain. In some embodiments, the number of available time domain resources, i.e., the number of symbols that the SRS resource may occupy, may be 1, 2, 4, 8, 10, 12, 14, etc. In some embodiments, the number of symbols occupied by the SRS resource may be configured by a high-level parameter nrofSymbol in the configuration information. In some embodiments, the position of the starting symbol of the SRS resource may be 0, 1, 2, 3, 4, 5, etc. In some embodiments, the position of the starting symbol of the SRS resource may be configured by a high-level parameter startPosition in the configuration information.

[0161] Figure 2 is a schematic diagram of the mapping of SRS resources onto time-frequency domain resources. As shown in Figure 2, three SRS resources are mapped onto the time-frequency domain resources: the first SRS resource, the second SRS resource, and the third SRS resource. The first SRS resource occupies one symbol in the time domain and is the third symbol from the last symbol in the timeslot where the first SRS resource is located. The higher-level parameters nrofSymbol and startPosition associated with the first SRS resource can be 1 and 3, respectively. The second SRS resource occupies four symbols in the time domain and the last symbol of the second SRS resource is the second symbol from the last symbol in the timeslot where the second SRS resource is located. The higher-level parameters nrofSymbol and startPosition associated with the second SRS resource can be 4 and 2, respectively. The third SRS resource occupies two symbols in the time domain and the last symbol of the third SRS resource is the zeroth symbol from the last symbol in the timeslot where the third SRS resource is located. The higher-level parameters nrofSymbol and startPosition associated with the third SRS resource can be 2 and 0, respectively.

[0162] The SRS resources can be arranged in a comb-like manner in the frequency domain. That is to say, the subcarriers occupied by an SRS resource are arranged at equal intervals. Obviously, the subcarriers occupied by an SRS resource are non-continuous. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resources in the frequency domain can be 2, 4, etc. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resources in the frequency domain can be configured by the high-level parameter transmissionComb in the configuration information. In some embodiments, the offset of the subcarriers occupied by the SRS resources in the frequency domain can be 0, 1, 2, 3, etc. In some embodiments, the offset of the subcarriers occupied by the SRS resources in the frequency domain can be configured by the high-level parameter combOffset in the configuration information.

[0163] Continuing with Figure 2, the first SRS resource is arranged in a comb-like pattern in the frequency domain, with an arrangement period of 2, and the offset of the first occupied subcarrier relative to the first subcarrier (lower edge) of the time-frequency resource is 0. The high-level parameters transmissionComb and combOffset related to the first SRS resource can be 2 and 0, respectively. Similarly, the high-level parameters transmissionComb and combOffset related to the second SRS resource can be 2 and 1, respectively, and the high-level parameters transmissionComb and combOffset related to the third SRS resource can be 4 and 0, respectively.

[0164] In some embodiments, the mapping of an 8-port SRS resource (i.e., an SRS resource supporting 8 SRS ports) to time-frequency resources can be performed using either time division multiplexing (TDM) or non-TDM. In some embodiments, whether the 8-port SRS resource uses the TDM method can be configured using the higher-level parameter transmissionComb in the configuration information. In some embodiments, for the non-TDM method, the mapping of the 8-port SRS resource to time-frequency resources can be achieved by arranging different combinations of period, subcarrier offset, and cyclic shift. In one example, the higher-level parameter transmissionComb associated with the 8-port SRS resource can be 2, and different cyclic shifts can be used. In another example, the higher-level parameter transmissionComb associated with the 8-port SRS resource can be 4 or 8, and different subcarrier offsets and cyclic shifts can be used. In some embodiments, for the TDM method, the 8-port SRS resource can occupy multiple symbols. In one example, the 8-port SRS resource can occupy 2 symbols. In this case, the 8 SRS ports corresponding to the 8-port SRS resource can be divided into two SRS port subsets. Each SRS port subset can include 4 SRS ports. For example, a first subset of SRS ports may include ports 0, 1, 4, 5, and a second subset of SRS ports may include ports 2, 3, 6, 7.

[0165] In order to implement codebook-based uplink transmission (for example, physical uplink shared channel (PUSCH)), the SRS resource set configured by the access network device for the terminal can be applicable to codebook-based uplink transmission. The SRS resource set may include one or more SRS resources. After receiving the SRS sent by the terminal through the SRS resource, the access network device may send an SRS resource indication (SRS resource indication, SRI) to the terminal to indicate the selected SRS resource. At the same time, the access network device may determine the precoding matrix and number of transmission layers used by the terminal for actual transmission, and notify the terminal through the transmit precoding matrix indicator (TPMI) and rank indicator (RI) respectively. The terminal precodes the data according to the TPMI and RI, and uses the antenna port corresponding to the SRS resource indicated by the SRI to send the precoded data.

[0166] With the development of communication technology, a terminal may have three transmitting antennas. In this case, the access network equipment needs to be able to configure corresponding SRS resources for the terminal.

In one example, the number of antenna ports of terminal 101 may be equal to 3. In other words, the number of transmit antennas of terminal 101 may be equal to 3.

[0178] In some embodiments, the port parameters of the transmitting antenna may be carried in the srs-TxSwitch information element.

[0179] In some embodiments, the capability information may be carried in upper layer signaling, for example, signaling in a radio resource control (RRC) process.

[0180] In some embodiments, the capability information may be carried in a UE Capability Information message. In one example, the UE Capability Information message may be transmitted during an RRC process. In some embodiments, the UE Capability Information message may be sent by terminal 101 in response to a UE Capability Information Query message from network device 102. In some embodiments, the UE Capability Information message may be proactively sent by terminal 101.

[0181] In some embodiments, network device 102 may not receive capability information.

[0185] In some embodiments, the first information may be used to configure an SRS resource set. The SRS resource set includes at least one 3-port SRS resource.

[0186] In some embodiments, the first information may be used to indicate the configuration of the SRS resource set to the terminal 101 .

[0187] In some embodiments, the name of the first information is not limited, and it can be, for example, configuration information, SRS resource configuration information, resource configuration information, SRS resource indication information, SRS resource parameter information, etc. The embodiments of the present disclosure do not make specific limitations on this.

[0190] In some embodiments, the number of SRS resource sets may be equal to 1. The SRS resource set may include at least one 3-port SRS resource.

[0191] In some embodiments, the SRS resource set can function as a codebook. That is, a three-port SRS resource in the SRS resource set can obtain uplink CSI via the three SRS ports. In some embodiments, the CSI can be used for codebook-based PUSCH transmission. In other words, the CSI can be used for codebook-based PUSCH transmission.

[0192] In some embodiments, a 3-port SRS resource may be implemented based on the first SRS resource.

[0193] In some embodiments, the 3-port SRS resource can be implemented by repeating the first SRS resource on the time domain resource. It can be understood that the 3-port SRS resource obtained based on the repetition of the first SRS resource can be called an "equivalent" 3-port SRS resource.

[0194] In some embodiments, the first SRS resource may include one of the following: a 1-port SRS resource (or referred to as a single-port SRS resource) or a 2-port SRS resource.

[0195] In some embodiments, the first information may include a first information element.

[0196] In some embodiments, the first information element may be used to indicate that the number of ports of a 3-port SRS resource in an SRS resource set is 3. In some embodiments, the first information element may be used to configure the number of SRS ports associated with the SRS resource set to 3. In one example, the first information element may be used to indicate that the number of SRS ports associated with the SRS resource set is 3. For example, the first information element may be used to directly indicate that the value of the SRS port number is 3. In one example, the first information element may be used to enable the number of SRS ports associated with the SRS resource set to be 3. For example, the first information element may be used to enable an SRS port number parameter. The SRS port number parameter indicates that the SRS port number is 3. After being enabled by the first information element, the SRS port number parameter takes effect.

[0197] In some embodiments, the first information may include the second information element.

[0198] In some embodiments, the second information element may be used to configure the number of symbols occupied by the 3-port SRS resource in the time domain.

[0199] In some embodiments, the second information element may be used to indicate the number of time domain resources occupied by the 3-port SRS resource.

[0200] In some embodiments, the symbols occupied by the 3-port SRS resource in the time domain may be continuous.

[0201] In some embodiments, the second information element may be used to indicate the number of symbols occupied by the 3-port SRS resource derived from the first SRS resource in the time domain. In other words, the second information element may be used to indicate the number of symbols occupied by the 3-port SRS resource in a time slot.

[0202] In some embodiments, the second information element may be used to indicate the number of symbols occupied by the first SRS resource in a time slot.

[0203] In some embodiments, the second information element may include the number of symbols occupied by the 3-port SRS resource and the number of symbols occupied by the first SRS resource, or may include one of the number of symbols occupied by the 3-port SRS resource and the number of symbols occupied by the first SRS resource.

[0208] In some embodiments, the third information element may be used to indicate the number of repetitions corresponding to the first SRS resource.

[0209] In some embodiments, the number of repetitions corresponding to the first SRS resource may be predefined. In this case, the first information may not include the third information element.

[0210] In some embodiments, a 3-port SRS resource can be implemented by repeating the first SRS resource in the time domain with a repetition number. To implement the 3-port SRS resource, the repetition number of the first SRS resource can correspond to the first SRS resource. In one example, the first SRS resource can be a 1-port SRS resource, and the corresponding repetition number can be 3. The number of symbols occupied by the 3-port SRS resource can be equal to the number of symbols occupied by the 1-port SRS resource multiplied by 3. In one example, the first SRS resource can be a 2-port SRS resource, and the corresponding repetition number can be 2. The number of symbols occupied by the 3-port SRS resource can be equal to the number of symbols occupied by the 2-port SRS resource multiplied by 2.

[0211] In some embodiments, the first information may include a fourth information element.

[0212] In some embodiments, when a 3-port SRS resource is implemented by repetition of a 2-port SRS resource in the time domain, the first 2-port SRS resource may correspond to the first port and the second port, and the second 2-port SRS resource may correspond to the third port and the fourth port. Three of the first port, the second port, the third port, and the fourth port may each correspond to three SRS ports.

[0213] In some embodiments, the fourth information element may be used to indicate the fifth port.

[0216] In some embodiments, the fourth information element may include first indication information.

[0217] In some embodiments, the first indication information may be used to indicate the fifth port.

[0218] In some embodiments, the name of the first indication information is not specifically limited, and it can be, for example, port removal (drop) indication information, port ignore indication information, etc.

[0219] In some embodiments, the first indication information may include an index value of the fifth port.

[0220] In some embodiments, the fourth information element may include a bitmap.

[0221] In some embodiments, the bitmap may include 4 bits. These 4 bits correspond to the first port, the second port, the third port, and the fourth port, respectively. Each bit is used to indicate whether the corresponding port is removed. In one example, the value of the bitmap may be [1, 1, 1, 0], where the value of the first three bits is 1, which indicates that the first port, the second port, and the third port are adopted; the value of the fourth bit is 0, which indicates that the fourth port is removed. In other words, the bit with a value of 0 corresponds to the fifth port. In one example, the value of the bitmap may be [0, 1, 0, 0], where the value of the first, third, and fourth bits is 0, which indicates that the first port, the third port, and the fourth port are adopted; the value of the second bit is 1, which indicates that the second port is removed. In other words, the bit with a value of 1 corresponds to the fifth port.

[0222] In some embodiments, the first information may include a fifth information element.

[0223] In some embodiments, the fifth information element may be used to configure the function as a codebook.

[0224] In some embodiments, the fifth information element may be used to configure the function of the SRS resource set as a codebook.

[0225] In some embodiments, the fifth information element may be used to indicate that the SRS resource set is used as a codebook.

[0226] In some embodiments, the fifth information element may be a usage information element. In one example, the value of the usage information element may be equal to "codebook," indicating that the usage is codebook. For example, the value range of the usage information element may be {beamManagement, codebook, nonCodebook, antennaSwitching}. Therefore, for terminal 101, the value of the usage information element in the first message may be equal to codebook. Of course, the fifth information element may also be other information elements or signaling, which is not specifically limited in the present embodiment.

[0227] In some embodiments, the first information may include a sixth information element.

[0228] In some embodiments, the sixth information element may be used to configure the first resource type.

[0229] In some embodiments, the sixth information element may be used to configure the resource type of the SRS resource set to be the first resource type.

[0232] In some embodiments, resource types may include: periodic, semi-persistent, aperiodic

[0233] In some embodiments, the first resource type may be one of the following: periodic, semi-persistent, or aperiodic.

[0234] In some embodiments, the sixth information element may be a resourceType information element. In one example, the value range of the resourceType information element may be {periodic, semi-persistent, aperiodic}. Therefore, for terminal 101, the value of the resourceType information element in the first message may be equal to any one of periodic, semi-persistent, and aperiodic. Of course, the sixth information element may also be other information elements or signaling, and this is not specifically limited in the present embodiment.

[0250] In some embodiments, the seventh information element may be associated with one of the following: an SRS resource set, a first SRS resource. In some embodiments, the seventh information element may be set in an information element for an SRS resource set. In one example, the seventh information element may be set in an information element corresponding to an SRS resource set.

In one example, the seventh information element may be set in an information element corresponding to a first SRS resource. For example, the seventh information element may be set in an SRS-Resource information element.

[0251] In some embodiments, different first SRS resources in an SRS resource set may correspond to different beam directions. That is, different three-port SRS resources in different SRS resource sets may correspond to different beam directions. In some embodiments, the seventh information element associated with different first SRS resources may have different values, thereby configuring different beam directions for different first SRS resources.

[0252] In some embodiments, an SRS resource set may include two 3-port SRS resources. The first SRS resources corresponding to the two 3-port SRS resources may be the same or different. In one example, the two first SRS resources in the SRS resource set may both be 1-port SRS resources. In another example, the two first SRS resources in the SRS resource set may both be 2-port SRS resources. In another example, the two first SRS resources in the SRS resource set may be a 1-port SRS resource and a 2-port SRS resource, respectively.

[0253] In some embodiments, the configured available time domain resources may be greater than or equal to the number of symbols occupied by the three SRS ports. In one example, when the available time domain resources include four symbols and the number of symbols occupied by the one-port SRS resource is two, the number of symbols occupied by the one-port SRS resource corresponding to each repetition may be reduced from two to one. In this way, the number of symbols occupied by the three-port SRS resource resulting from the repetition of the one-port SRS resource can be reduced from six to three. In one example, when the available time domain resources include five symbols and the number of symbols occupied by the one-port SRS resource is two, the number of symbols occupied by the one-port SRS resource corresponding to any one repetition may be reduced from two to one. In this way, the number of symbols occupied by the three-port SRS resource resulting from the repetition of the one-port SRS resource can be reduced from six to five.

[0254] In step S303 , the terminal 101 sends an SRS to the network device 102 .

[0255] In some embodiments, terminal 101 may send SRS via a configured 3-port SRS resource.

[0256] In some embodiments, the SRS may be transmitted via three transmit antennas of the terminal 101. The three transmit antennas may correspond to three SRS ports of a three-port SRS resource.

[0257] In some embodiments, network device 102 may receive an SRS.

[0258] In some embodiments, SRS may be transmitted in 1 or 2 beam directions.

[0259] In some embodiments, the first SRS resource may be repeated in the time domain to determine a 3-port SRS resource and determine the 3 SRS ports corresponding to the 3-port SRS resource.

[0260] In some embodiments, the number of repetitions corresponding to the first SRS resource may be determined based on the third information element. In one example, the number of repetitions may be directly determined based on the third information element.

[0261] In some embodiments, the number of repetitions corresponding to the first SRS resource can be obtained using a predefined method. In some embodiments, the number of repetitions corresponding to the first SRS resource can be associated with the number of ports of the first SRS resource. In one example, according to the predefined method, the number of repetitions corresponding to a 1-port SRS resource can be 3. In another example, according to the predefined method, the number of repetitions corresponding to a 2-port SRS resource can be 2.

[0262] In some embodiments, the number of repetitions corresponding to the first SRS resource can be obtained based on the second information element. In this case, the second information element can implicitly indicate the number of repetitions. In one example, the second information element may include the number of symbols occupied by the 3-port SRS resource and the number of symbols occupied by the first SRS resource. At this time, the number of repetitions can be determined based on the number of symbols occupied by the 3-port SRS resource and the number of symbols occupied by the first SRS resource. In one example, the number of repetitions can be equal to the number of symbols occupied by the 3-port SRS resource divided by the number of symbols occupied by the first SRS resource. For example, in the case where the second information element includes the number of symbols occupied by the 3-port SRS resource and the number of symbols occupied by the 1-port SRS resource, the number of repetitions can be equal to the number of symbols occupied by the 3-port SRS resource divided by the number of symbols occupied by the 1-port SRS resource.

[0263] In some embodiments, the first SRS resource may be a 1-port SRS resource, and the number of repetitions may be 3. Thus, the ports of the three 1-port SRS resources repeated at different time domain positions may correspond to three SRS ports, respectively.

[0264] In some embodiments, the index values ​​of the three SRS ports of the 3-port SRS resource may be {0, 1, 2} respectively. It is understandable that the three SRS ports may also have other index values, which are not specifically limited in the embodiments of the present disclosure.

[0265] In some embodiments, the 1-port SRS resource repeated three times may correspond to the first port, the second port, and the third port, respectively. The mapping relationship between the first port, the second port, the third port and the three SRS ports {0, 1, 2} can be seen in Table 1 below.

[0266] Table 1: Mapping between the ports of a repeated 1-port SRS resource and the three SRS ports

[0267] In some embodiments, the first SRS resource may be a 2-port SRS resource, and the number of repetitions may be equal to 2. Thus, three ports out of a total of four ports (respectively, the first port, the second port, the third port, and the fourth port) of the two 2-port SRS resources repeated at different time domain positions may correspond to three SRS ports, respectively.

[0268] In some embodiments, the 2-port SRS resource repeated twice may correspond to the first port, the second port, the third port, and the fourth port, respectively. The mapping relationship between the first port, the second port, the third port, the fourth port and the three SRS ports {0, 1, 2} can be seen in Table 2 below.

[0269] Table 2: Mapping between each port of the repeated 2-port SRS resource and the three SRS ports

[0270] In some embodiments, three of the first port, the second port, the third port, and the fourth port may correspond to three SRS ports, respectively. These three ports may be determined by removing the fifth port.

[0271] In some embodiments, the fifth port may be determined in one of the following ways: predefined, signaling configuration, or determined according to the first parameter.

[0272] In some embodiments, the index values ​​of the first port, the second port, the third port, and the fourth port may be {0, 1, 2, 3}, respectively. It is understood that the first port, the second port, the third port, and the fourth port may also have other index values, which are not specifically limited in the embodiments of the present disclosure.

[0273] In some embodiments, in a predefined manner, the fifth port can be one of the following: the port with the smallest index value, or the port with the largest index value. In one example, the fifth port can be SRS port {0}. In another example, the fifth port can be SRS port {3}. Of course, the fifth port can also be other ports, and this is not specifically limited in the embodiments of the present disclosure.

[0274] In some embodiments, in a signaling configuration mode, the fifth port may be determined according to the fourth information element.

[0275] In some embodiments, the fifth port may be configured in one of the following ways: indication information, bitmap.

[0276] In some embodiments, the fifth port may be determined by the first parameter. In this case, it can be understood that the fifth port is implicitly determined.

[0277] In some sets of embodiments, the first parameter may be a parameter in the combOffset information element. In one example, the index value of the fifth port may be determined by taking the value of the combOffset information element modulo 4.

[0278] FIG4A is a schematic diagram of a first mapping relationship between a 3-port SRS resource and 3 SRS ports in an embodiment of the present disclosure. As shown in FIG4A , the 3-port SRS resource can be obtained by repeating a 1-port SRS resource 3 times in the time domain. The number of symbols occupied by the corresponding 1-port SRS resource each time can be 1. The 3-port SRS resource obtained by repeating the 1-port SRS resource 3 times can occupy 3 consecutive symbols. The 1-port SRS resource corresponding to the first symbol can correspond to SRS port {0}. The 1-port SRS resource corresponding to the second symbol can correspond to SRS port {1}. The 1-port SRS resource corresponding to the third symbol can correspond to SRS port {2}.

[0279] Figure 4B is a schematic diagram of the second mapping relationship between a 3-port SRS resource and three SRS ports in an embodiment of the present disclosure. As shown in Figure 4B, the 3-port SRS resource can be obtained by repeating the 2-port SRS resource twice in the time domain. The number of symbols occupied by the corresponding 2-port SRS resource each time can be 2. The 3-port SRS resource obtained by repeating the 2-port SRS resource twice can occupy 4 consecutive symbols. The two ports of the 2-port SRS resource corresponding to the first two symbols can correspond to SRS ports {0, 1}. One port of the 2-port SRS resource corresponding to the last two symbols can correspond to SRS port {2}. The other port of the 2-port SRS resource corresponding to the last two symbols is removed and not sent.

[0280] In some embodiments, for example, each SRS port {0, 1, 2} in FIG. 4A and FIG. 4B may also have other index numbers (ie, port numbers), such as {1000, 1001, 1002}, which is not specifically limited in the embodiments of the present disclosure.

[0281] In some embodiments, the SRS resources actually allocated by network device 102 can satisfy the transmission of 3-port SRS resources. In this case, the available time domain resources can be greater than or equal to the product of the first SRS resource and the corresponding number of repetitions. In one example, for a 1-port SRS resource occupying 1 symbol, the available time domain resources can be greater than or equal to 3 symbols. In another example, for a 1-port SRS resource occupying 2 symbols, the available time domain resources can be greater than or equal to 6 symbols. In another example, for a 2-port SRS resource occupying 3 symbols, the available time domain resources can be greater than or equal to 6 symbols.

[0282] In some embodiments, the available time domain resources may be consecutive symbols that may be allocated for 3-port SRS resource transmission within a time slot.

[0283] In some embodiments, the symbols occupied by the 3-port SRS resource may collide with the symbols occupied by the first uplink resource. The available time domain resources do not include the colliding symbols.

[0284] In some embodiments, the first uplink resource may be used to carry at least one of the following: an uplink channel, an uplink signal.

[0285] In some embodiments, the symbol occupied by the 3-port SRS resource may be the first symbol, and the symbol occupied by the first uplink resource may be the second symbol.

[0286] In some embodiments, the first symbol and the second symbol may partially conflict with each other. In some embodiments, at least one symbol in the first symbol may be identical to at least one symbol in the second symbol. Identical symbols may be referred to as conflicting symbols.

[0287] In some embodiments, the first uplink resource may have a higher priority than the 3-port SRS resource.

[0288] In some embodiments, when the first symbol and the second symbol partially collide, the terminal 101 may determine not to send the SRS. In this case, the network device 102 may not expect the terminal 101 to send the SRS.

[0289] In some embodiments, when the first symbol and the second symbol partially collide, the terminal 101 may transmit the SRS on the remaining symbols in the first symbol except the collided symbol.

[0290] In some embodiments, when the remaining symbols excluding the collision symbol in the first symbol include symbols corresponding to all of the three SRS ports, the terminal 101 may transmit the SRS on the remaining symbols. In some embodiments, when the remaining symbols excluding the collision symbol in the first symbol include symbols corresponding to some of the three SRS ports, the terminal 101 may determine not to transmit the SRS.

[0291] It should be noted that, when the number of consecutive symbols occupied by the 3-port SRS resources may be greater than the available time domain resources, the terminal 101 may also adopt other methods for processing, which is not specifically limited in the embodiments of the present disclosure.

[0292] In step S304 , the network device 102 sends second information to the terminal 101 .

[0293] In some embodiments, terminal 101 may receive second information.

[0294] In some embodiments, the second information may be used to indicate the first SRS resource.

[0295] In some embodiments, the name of the second information is not limited, and it can be, for example, resource indication information, resource scheduling information, SRS resource indication information, etc.

[0296] In some embodiments, the second information may be carried in downlink control information (DCI) signaling.

[0297] In some embodiments, the DCI signaling may be carried in a physical downlink control channel (PDCCH).

[0298] In some embodiments, the second information may include an eighth information element.

[0299] In some embodiments, the eighth information element may be used to indicate the first SRS resource.

[0300] In some embodiments, the eighth information element may be used to indicate a first SRS resource used for PUSCH transmission based on a codebook, where the first resource is a 3-port SRS resource in an SRS resource set.

[0301] In some embodiments, the eighth information element may be an SRS resource indication.

[0302] In some embodiments, the eighth information element may be an SRI (SRS resource indicator) information element.

[0303] In some embodiments, the SRS resource set may include one 3-port SRS resource. The number of bits of the eighth information element may be 0. In other words, the fourth information element may be omitted. In one example, the second information may indicate the 3-port SRS resource by default.

[0304] In some embodiments, the SRS resource set may include two 3-port SRS resources. The number of bits in the fourth information element may be 1. Different values ​​of the fourth information element may be used to indicate different 3-port SRS resources. In one example, if the value of the fourth information element is "0," it may indicate the first 3-port SRS resource; if the value of the fourth information element is "1," it may indicate the second 3-port SRS resource. In another example, if the value of the fourth information element is "1," it may indicate the first 3-port SRS resource; if the value of the fourth information element is "0," it may indicate the second 3-port SRS resource.

[0305] In step S305 , the terminal 101 sends a PUSCH to the network device 102 .

[0306] In some embodiments, network device 102 may receive the PUSCH.

[0307] In some embodiments, the terminal 101 may perform codebook-based PUSCH transmission using the first SRS resource specified by the second information.

[0308] In some embodiments, the terminal 101 may perform codebook-based PUSCH transmission through an SRS port corresponding to the first SRS resource specified by the second information.
