[0002] The uplink transmit spatial filter (UL Tx spatial filter) is generally corresponding to the uplink transmit beam. During uplink transmission, the uplink transmit spatial filter needs to be determined to transmit SRS.

[0003] However, in related technologies, terminal devices determine the uplink transmission space filter based on the TCI state. The TCI state is configured by the network device, meaning that the terminal device determines the uplink transmission space filter according to the TCI state configured by the network device. This limits the flexibility of the terminal device in determining the uplink transmission space filter, resulting in poor flexibility in the determination of the uplink transmission space filter.

[0136] To make the technical problems, technical solutions and advantages of this application clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0137] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0138] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0139] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0140] In wireless communication systems (such as Long Term Evolution (LTE) systems, New Radio (NR) systems, etc.), the general formula for calculating the uplink transmission power P in related technologies can be:

[0141] P = min{P CMAX {Open-loop operating point} + {Closed-loop offset} + {Other adjustment values};

[0142] In NR and LTE systems, one specific approach is as follows:

[0143] P = min{P CMAX ,{P0(j)+α(k)PL(q)}+{f(l)}+{10log 10 M+Δ};

[0144] That is, the open-loop operating point is determined by P0(j) + α(k)PL(q), the closed-loop offset is determined by f(l), and other adjustment quantities are determined by 10log 10 M+Δ is determined.

[0145] Where P0(j) is the open-loop receiver power target value, and j is an index used to select one from a set of P0 values. Optionally, when there is only one value for j, (j) is omitted.

[0146] PL(q) is the path loss estimate, and q is an index used to select one from a set of path loss estimates maintained by the terminal equipment (UE), or an index used to represent the reference signal used to determine the path loss PL(q). Optionally, when there is only one q value, (q) is omitted.

[0147] α(k) is a partial road loss compensation factor, ranging from 0 to 1, and k is an index used to select one from multiple index values. Optionally, when there is only one k value, (k) is omitted.

[0148] The closed-loop part f(l) is the power control adjustment state value with index l.

[0149] Other adjustment variables are mainly related to resource allocation and link adaptation. M is the adjustment variable related to the bandwidth allocated for this uplink transmission, and Δ is the adjustment variable related to the modulation and coding scheme (MCS) of this uplink transmission.

[0150] P CMAX Configure transmission power; maximum allowed transmission power.

[0151] Taking the NR system as an example, the transmission power of the Sounding Reference Signal (SRS) can be calculated using the formulas in the relevant specifications, and f(l) and other parameters can also be calculated using the formulas in the relevant specifications, so we will not go into details here.

[0152] In related technologies, an SRS resource set can be configured to be associated with a Transmission Configuration Indicator (TCI) state. Specifically, there are several ways:

[0153] Method 1: Configure the associated TCI state for the SRS resource set. For example, instruct the SRS resource set to follow a unified TCI state, and specify which of one or more TCI states is indicated by Radio Resource Control (RRC) parameter configuration, Media Access Control-Control Element (MAC-CE) activation, or Downlink Control Information (DCI).

[0154] Method 2: Configure the associated TCI state for each SRS resource in the SRS resource set. Specifically, you can configure the TCI state associated with each SRS resource in the SRS resource set; or you can configure the TCI state associated with each of the SRS resources in the SRS resource set.

[0155] The TCI state associated with an SRS resource set is used to determine the power control parameters corresponding to the SRS transmission. Optionally, it is also used to determine the UL Tx spatial filter (uplink transmit spatial filter, generally considered to correspond to the uplink transmit beam) for the SRS transmission. Specifically, if an SRS resource set is associated with a TCI state (e.g., the SRS resource is configured with the RRC parameter followUnifiedTCI-StateSRS), then all SRS resources in this SRS resource set are associated with this TCI state, and power transmission is determined based on the power control parameters associated with this TCI state. If there is an SRS resource associated with a TCI state in the SRS resource set, the UE can determine the power control parameters for the SRS transmission corresponding to the SRS resource in the SRS resource set based on the power control parameters associated with the TCI state of the SRS resource with the smallest ID in the SRS resource set. If an SRS associated with a TCI state is configured with a QCL-Type D RS, this RS is used to determine the UL Tx spatial filter corresponding to the SRS. Power control parameters associated with a TCI state can be configured in the RRC signaling that configures the TCI state, or in the MAC-CE signaling and / or DCI signaling that indicates / updates the power control parameters associated with the TCI state. Optionally, the Information Element (IE) corresponding to the TCI state includes parameters for indicating path loss reference signals and / or path loss offsets. Optionally, the IE corresponding to the TCI state includes parameters for configuring uplink power control parameters, which include parameters for indicating at least one of p0, α, closed-loop power control parameters (e.g., closedLoopIndex).

[0156] For some SRS transmissions, especially those used for uplink transmit beam scanning, configuring the corresponding UL Tx spatial filter for SRS transmissions by the base station through the TCI state is not a good approach. This is because the base station is unaware of which transmit beams the UE has (corresponding to the UL Tx spatial filter) and which beams should be used to transmit SRS. Therefore, it is necessary to allow the UE to select the transmit beams for SRS independently. That is, to allow an SRS resource set (including its constituent SRS resources) to not determine the transmit beams based on the TCI state. However, if the base station does not configure its associated TCI state for the SRS resource set, nor for any SRS resource within that set, it becomes unclear how to determine the power control parameters for the SRS transmissions corresponding to that SRS resource set. If other power control parameter determination mechanisms are used, i.e., those not based on the TCI state, some SRS will determine their power control parameters based on the TCI state, while others will use other mechanisms. Both the base station and the UE would need to maintain multiple mechanisms, increasing complexity.

[0157] In addition, for determining the UL Tx spatial filter for SRS transmission, the UE generally determines it according to the TCI state specified by the base station. That is, the terminal device determines the uplink transmission spatial filter according to the TCI state configured by the network device, which limits the flexibility of the terminal device in determining the uplink transmission spatial filter.

[0158] Based on this, embodiments of this application provide a method for determining transmission parameters, a communication device, and a storage medium to solve the problem of poor flexibility in determining the uplink transmission spatial filter.

[0159] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0160] The technical solutions provided in this application can be applied to various systems, especially 6G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), 5G New Radio (NR), and 6G systems. All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G systems (5GS).

[0161] Please see Figure 1 , Figure 1 This is a schematic diagram of the network architecture applicable to the implementation of this application, such as... Figure 1 As shown, it includes terminal 11 and network device 12.

[0162] The terminal involved in this application embodiment can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), Redcap terminals, and Low Power Wide Area (LPWA) terminals. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile terminal, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this application does not limit the terminology used in its embodiments.

[0163] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) network, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a base station in 6G, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may also be geographically separated.

[0164] Network devices and terminals can each use one or more antennas for Multiple-Input Multiple-Output (MIMO) transmission. MIMO transmission can be Single-User MIMO (SU-MIMO) or Multiple-User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0165] Please see Figure 2 , Figure 2 This is a flowchart of a method for determining transmission parameters provided in an embodiment of this application. This method can be applied to a terminal device (UE), such as... Figure 2 As shown, it includes the following steps:

[0166] Step 201: Determine the TCI state corresponding to the uplink signal;

[0167] Step 202: Based on the target information sent by the network device, determine whether to determine the uplink transmission space filter for transmitting uplink signals based on the TCI status.

[0168] It should be noted that the uplink signal can be, but is not limited to, SRS, Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), etc. Network devices can be, but are not limited to, base stations.

[0169] Terminal devices can transmit uplink signals via an uplink transmit spatial filter (UL Tx spatial filter). The terminal device can first determine the uplink transmit spatial filter. During the process of determining the uplink transmit spatial filter for transmitting the uplink signal, the terminal device can determine whether to determine the uplink transmit spatial filter based on the TCI state based on target information sent by the network device. For example, the aforementioned target information can be information sent by the network device through at least one of the following: Radio Resource Control (RRC) signaling; Media Access Control-Control Element (MAC-CE) signaling; Downlink Control Information (DCI) signaling. The target information can be understood as information that can be used to indicate whether the terminal device uses the TCI state to determine the uplink transmit spatial filter for transmitting the uplink signal. For example, determining the TCI state corresponding to the uplink signal can be done through target signaling sent by the network device. The target signaling can indicate the TCI state corresponding to the uplink signal; that is, the TCI state corresponding to the uplink signal can be indicated by the network device. For example, the target signaling may include, but is not limited to, at least one of RRC signaling, MAC-CE signaling, and DIC signaling. It should also be noted that the RRC signaling, MAC-CE signaling, and DIC signaling in the target signaling may be the same as or different from the RRC signaling, MAC-CE signaling, and DIC signaling used to send the target information.

[0170] Additionally, it should be noted that if the uplink transmission space filter is not determined based on the TCI state, other methods can be used to determine it. For example, it can be determined by selecting a method from relevant technologies (such as relevant protocols / specifications). No specific limitations are made here.

[0171] In the method of this application embodiment, the terminal device can determine whether to determine the uplink transmission spatial filter based on the TCI state of the uplink signal according to the target information sent by the network device. It can be understood that, according to the target information, the uplink transmission spatial filter can be determined based on the TCI state, or it can be determined not to determine the uplink transmission spatial filter based on the TCI state. In this way, the terminal device can choose different methods to determine the uplink transmission spatial filter, reduce the limitations of the terminal device in determining the uplink transmission spatial filter, and improve the flexibility of the terminal device in determining the uplink transmission spatial filter.

[0172] In some embodiments, determining whether to determine an uplink transmission spatial filter for transmitting uplink signals based on TCI status, based on target information sent by the network device, includes at least one of the following A1-A4:

[0173] A1: When the indication information in the target information indicates the first state or the first value, the uplink transmission space filter is determined based on the TCI state.

[0174] In other words, the target information includes indication information, which can indicate a state / value. Different processing is performed based on different states / values ​​indicated by the indication information. For example, in this example, when the indication information indicates a first state / first value, the UE can determine the UL Tx spatial filter for transmitting uplink signals based on the TCI state. It should be noted that the first state / first value can be a state / value predetermined by the protocol. It can be understood that the first state can be a state indicating that the TCI state needs to be used to determine the uplink transmission spatial filter, and the first value can be a value indicating that the TCI state needs to be used to determine the uplink transmission spatial filter. It can also be understood that the first value follows the TCI state.

[0175] A2: If the indication information in the target information indicates a second state or a second value, determine that the uplink transmission space filter is not determined based on the TCI state.

[0176] In this example, when the indication information indicates a second state / second value, the UE can determine that it will not determine the UL Tx spatial filter for transmitting uplink signals based on the TCI state. It should be noted that the second state / second value can be a pre-defined state / value in the protocol. It can be understood that the second state can be a state indicating that the TCI state is not needed to determine the uplink transmission spatial filter, and the second value can be a value indicating that the TCI state is not needed to determine the uplink transmission spatial filter; for example, the second value is a value that does not follow the TCI state (notFollowTCIstate).

[0177] That is, for A1 and A2 above, the uplink transmission space filter for transmitting uplink signals can be determined based on the value / state of the indication information in the target information.

[0178] A3: If the target information includes indication information, the uplink transmission spatial filter is determined based on the TCI state, and the indication information is used to indicate that the uplink transmission spatial filter is determined using the TCI state; or, if the target information includes indication information, it is determined that the uplink transmission spatial filter is not determined based on the TCI state, and the indication information is used to indicate that the uplink transmission spatial filter is not determined using the TCI state.

[0179] In this example, since the indication information can indicate different situations, it can be determined whether to determine the uplink transmission spatial filter based on the TCI state according to the different situations of the indication information. In this example, the target information includes indication information. If the indication information is used to indicate that the uplink transmission spatial filter is determined using the TCI state, then the terminal device determines the uplink transmission spatial filter based on the TCI state. If the indication information is used to indicate that the uplink transmission spatial filter is not used using the TCI state, then the terminal device determines that the uplink transmission spatial filter is not determined based on the TCI state.

[0180] A4: If the target information does not include indication information, determine that the uplink transmission spatial filter is not determined based on the TCI state, and the indication information is used to indicate that the uplink transmission spatial filter is determined using the TCI state; or, if the target information does not include indication information, determine the uplink transmission spatial filter based on the TCI state, and the indication information is used to indicate that the uplink transmission spatial filter is not determined using the TCI state.

[0181] In this example, the target information does not include indication information. If the indication information is used to indicate that the uplink transmission spatial filter is determined using the TCI state, that is, if the terminal device does not detect the indication information indicating that the uplink transmission spatial filter is determined using the TCI state, then the terminal device does not determine the uplink transmission spatial filter based on the TCI state. If the indication information is used to indicate that the uplink transmission spatial filter is not determined using the TCI state, that is, if the terminal device does not detect the indication information indicating that the uplink transmission spatial filter is not determined using the TCI state, then the terminal device determines that the uplink transmission spatial filter is determined based on the TCI state.

[0182] In other words, for A3 and A4 above, the determination of whether to use the UL Tx spatial filter for uplink signal transmission based on the TCI state can be based on whether the network device sends indication information. For example, the indication information is used to indicate the use of the TCI state to determine the uplink transmission spatial filter: if the target information includes the indication information, i.e., the indication information is detected, the UE determines the UL Tx spatial filter for uplink signal transmission based on the TCI state; if the indication information is not detected, the UE does not determine the UL Tx spatial filter for uplink signal transmission based on the TCI state; if the target information does not include the indication information, i.e., the indication information is not detected, the UE determines the UL Tx spatial filter for uplink signal transmission based on the TCI state; if the indication information is detected, the UE does not determine the UL Tx spatial filter for uplink signal transmission based on the TCI state. For example, the indication information is used to indicate that the uplink transmission spatial filter is not determined using the TCI state: if the target information does not include the indication information, that is, the indication information is not detected, the UE determines the UL Tx spatial filter for transmitting the uplink signal based on the TCI state; if the target information includes the indication information, that is, the indication information is detected, the UE does not determine the UL Tx spatial filter for transmitting the uplink signal based on the TCI state.

[0183] In this embodiment, in the process of determining whether to determine the uplink transmission space filter based on the TCI state based on the target information, it can be determined by any of the above methods, which can improve the flexibility of determining whether to determine the uplink transmission space filter based on the TCI state.

[0184] In some embodiments, the target information includes at least one of the following B1-B10:

[0185] B1: TCI status configuration information;

[0186] B2: Media Access Control-Control Unit (MAC-CE) signaling used to activate TCI status;

[0187] B3: MAC-CE signaling used to indicate the TCI status associated with an SRS resource or a set of SRS resources;

[0188] B4: Trigger signaling used to schedule uplink signals;

[0189] B5: SRS resource configuration information;

[0190] B6: SRS resource set configuration information;

[0191] B7: SRS configuration information;

[0192] B8: Bandwidth configuration information for BWP;

[0193] B9: Carrier configuration information;

[0194] B10: Community configuration information.

[0195] It should be understood that network devices carry this indication information through target information. For example, it can be carried through one or more of the following methods, including but not limited to RRC signaling (the configuration information of B1 and B5-B10 mentioned above can be information from RRC signaling), MAC-CE signaling, and DCI signaling (B4 mentioned above can be information from DCI signaling). For example, the indication information can be configured through RRC signaling and updated through MAC-CE signaling. Another example is configuring the indication information solely through RRC signaling.

[0196] In this embodiment, the target information may include at least one of the following: TCI status configuration information, Media Access Control-Control Unit (MAC-CE) signaling for activating the TCI status, MAC-CE signaling for indicating the TCI status associated with SRS resources or SRS resource sets, trigger information signaling, SRS resource configuration information, SRS resource set configuration information, SRS configuration information, Bandwidth Part (BWP) configuration information, carrier configuration information, and cell configuration information. That is, the indication information can be carried in at least one of these information and transmitted to the terminal device, so that the network device can configure the indication information to the terminal device, which can improve the flexibility of configuring the indication information.

[0197] In some embodiments, the TCI status configuration information is any of the following:

[0198] The TCI status configuration information is the TCI status configuration information associated with the SRS resource corresponding to the uplink signal.

[0199] The TCI status configuration information is the TCI status configuration information associated with the SRS resource set corresponding to the uplink signal.

[0200] The TCI status configuration information is the TCI status configuration information associated with the target SRS resource in the SRS resource set corresponding to the uplink signal.

[0201] In this implementation, the TCI status configuration information can be any of the three types of configuration information mentioned above, which can improve the flexibility of the TCI status configuration information. Since the TCI status configuration information can be used to configure indication information, the flexibility of configuring indication information can be improved.

[0202] In some embodiments, when the target information includes indication information, determining the uplink transmission spatial filter based on the TCI state includes at least one of the following C1-C2:

[0203] C1: When the target information includes the identifier of at least one SRS resource set and / or the identifier of an SRS resource, and the identifier of at least one SRS resource set and / or the identifier of an SRS resource includes the identifier of the SRS resource set corresponding to the uplink signal and / or the identifier of the SRS resource, the uplink transmission space filter is determined based on the TCI state.

[0204] It is understood that the indication information in this example can be the identifier of at least one SRS resource set and / or the identifier of an SRS resource. The need to determine the uplink transmission space filter based on the TCI state is determined implicitly in C1. In this example, not only must the target information include the identifier of at least one SRS resource set and / or the identifier of an SRS resource, but also the identifier of at least one SRS resource set and / or the identifier of an SRS resource must include the identifier of the SRS resource set corresponding to the uplink signal and / or the identifier of the SRS resource. Only then is it determined that the need to determine the uplink transmission space filter based on the TCI state is required.

[0205] C2: If the target information includes at least one TCI status identifier, and the TCI status corresponding to at least one TCI status identifier includes the TCI status corresponding to the uplink signal, determine the uplink transmission space filter based on the TCI status.

[0206] It is understood that the indication information in this example can be at least one TCI status identifier. The uplink transmission space filter needs to be determined based on the TCI status through the implicit method in C2. In this example, not only does the target information need to include at least one TCI status identifier, but the TCI status corresponding to at least one TCI status identifier also needs to include the TCI status corresponding to the uplink signal before it is determined that the uplink transmission space filter needs to be determined based on the TCI status.

[0207] In this implementation, at least one of the above-mentioned methods C1 and C2 can be selected to determine the uplink transmission space filter that needs to be determined based on the TCI state, which can improve the flexibility of determining the uplink transmission space filter.

[0208] In some embodiments, when the target information includes indication information, determining that the uplink transmit spatial filter is not determined based on the TCI state includes at least one of the following D1-D2:

[0209] D1: If the target information includes at least one SRS resource set and / or the identifier of an SRS resource, and the identifier of at least one SRS resource set and / or the identifier of an SRS resource includes the identifier of the SRS resource set and / or the SRS resource corresponding to the uplink signal, the uplink transmission space filter is not determined based on the TCI state.

[0210] It is understood that the indication information in this example can be the identifier of at least one SRS resource set and / or the identifier of an SRS resource. The uplink transmission space filter is not needed to be determined based on the TCI state by the implicit method in D1. In this example, not only is it required that the target information includes the identifier of at least one SRS resource set and / or the identifier of an SRS resource, but also that the identifier of at least one SRS resource set and / or the identifier of an SRS resource includes the identifier of the SRS resource set and / or the identifier of the SRS resource corresponding to the uplink signal, in order to determine that the uplink transmission space filter is not needed to be determined based on the TCI state.

[0211] D2: If the target information includes at least one TCI status identifier, and the TCI status corresponding to at least one TCI status identifier includes the TCI status corresponding to the uplink signal, the uplink transmission space filter is not determined based on the TCI status.

[0212] It is understood that the indication information in this example can be at least one TCI status identifier. The uplink transmission space filter is not needed to be determined based on the TCI status through the implicit method in D2. In this example, not only does the target information need to include at least one TCI status identifier, but the TCI status corresponding to at least one TCI status identifier also needs to include the TCI status corresponding to the uplink signal in order to determine that the uplink transmission space filter is not needed to be determined based on the TCI status.

[0213] In this implementation, at least one of the above-mentioned methods D1 and D2 can be selected to determine whether the uplink transmission space filter does not need to be determined based on the TCI state, which can improve the flexibility of determining whether the uplink transmission space filter does not need to be determined based on the TCI state.

[0214] For example, taking the uplink signal as SRS as an example, the process of determining whether to determine the uplink transmission space filter based on the TCI state is explained in detail:

[0215] Method 1: The target information is the TCI state configuration information, that is, the indication information is included in the TCI state configuration information (e.g., TCI-stateIE or TCI-UL-stateIE):

[0216] For example, in one instance, if the TCI state configuration information includes one or more SRS resource sets and / or SRS resource identifiers / lists (i.e., the TCI state configuration information includes at least one SRS resource set identifier and / or SRS resource identifier), and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources is determined based on the TCI state. Alternatively, if the TCI state configuration information includes one or more SRS resource sets and / or SRS resource identifiers / lists, and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources is not determined based on the TCI state.

[0217] For example, in one scenario, the TCI state configuration information includes a parameter corresponding to this indication information, assuming it includes two candidate values: followTCIstate (follows the TCI state) and notFollowTCIstate (does not follow the TCI state). The indication information is named srs-Spatialfilter. If the TCI configuration information includes this indication information and indicates followTCIstate (which could correspond to the first value / first state), the UE determines the UL Tx spatial filter for transmitting SRS based on the TCI state. If the TCI configuration information includes this indication information and indicates notFollowTCIstate (which could correspond to the second value / second state), the UE does not determine the UL Tx spatial filter for transmitting SRS based on the TCI state.

[0218] For example, in one scenario, the TCI state configuration information includes a parameter corresponding to this indication information. If the TCI configuration information includes the indication information, the UE determines the UL Tx spatial filter for transmitting SRS based on the TCI state; if the TCI configuration information does not include the indication information, the UE does not determine the UL Tx spatial filter for transmitting SRS based on the TCI state. Assuming there is one candidate value: disabled (i.e., indicating that the above TCI state is used to determine the uplink transmission spatial filter), this indication information can be named spatialfilterFollowTCIstate.

[0219] For example, in one scenario, the TCI state configuration information includes a parameter corresponding to this indication information. If the TCI configuration information does not contain the indication information, the UE determines the UL Tx spatial filter for transmitting SRS based on the TCI state; if the TCI configuration information includes the indication information, the UE does not determine the UL Tx spatial filter for transmitting SRS based on the TCI state. Assuming there is one candidate value: enabled (i.e., indicating that the TCI state is not used to determine the uplink transmission spatial filter), this indication information can be named disableSpatialfilterFollowTCIstate.

[0220] Method 2: The target information is the MAC-CE signaling used to activate the TCI state, that is, the MAC-CE signaling used to activate the TCI state includes this indication information:

[0221] For example, in one example, the parameter includes the indication information. This example is similar to the method in Method 1, which includes the parameter corresponding to the indication information. The difference is that in Method 2, the MAC-CE signaling used to activate the TCI state includes the parameter of the indication information, while in Method 1, the TCI configuration information includes the parameter of the indication information. This will not be elaborated further.

[0222] For example, in one instance, the MAC-CE may include multiple TCI states, each corresponding to a specific instruction.

[0223] For example, in one instance, the MAC-CE includes one or more SRS resource sets and / or SRS resource identifiers / lists (i.e., the MAC-CE signaling includes at least one SRS resource set and / or SRS resource identifier), and when the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources can be determined based on the TCI state. Alternatively, in another instance, when the MAC-CE includes one or more SRS resource sets and / or SRS resource identifiers / lists, and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources is not determined based on the TCI state.

[0224] Method 3: The target information is MAC-CE signaling used to indicate the TCI status of an SRS resource or a set of SRS resources, that is, the MAC-CE signaling used to indicate the TCI status of an SRS resource or a set of SRS resources includes this indication information:

[0225] For example, in one example, the parameter includes indication information. This example is similar to the method in Method 1, which includes the parameter corresponding to the indication information. The difference is that in Method 3, the MAC-CE signaling used to indicate the TCI status associated with the SRS resource or SRS resource set includes the parameter of indication information, while in Method 1, the TCI configuration information includes the parameter of indication information. This will not be elaborated further.

[0226] For example, in one instance, if the MAC-CE includes one or more TCI state identifiers / lists (i.e., the MAC-CE includes at least one TCI state identifier), and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state; however, for other TCI states, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state. Alternatively, if the MAC-CE includes one or more TCI state identifiers / lists, and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state; however, for other TCI states, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state.

[0227] Method 4: The target information is a trigger information signaling used to schedule uplink signals, that is, the trigger information signaling includes this indication information:

[0228] For example, in one example, the parameter includes the indication information. This example is similar to the method in method 1, which includes the parameter corresponding to the indication information. The difference is that in method 4, the parameter includes the indication information in the trigger information signaling, while in method 1, the parameter includes the indication information in the TCI configuration information. This will not be elaborated further.

[0229] For example, in one instance, if the triggering information signaling includes one or more TCI state identifiers / lists (i.e., the triggering information signaling includes at least one TCI state identifier), and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state. Alternatively, if the triggering information signaling includes one or more TCI state identifiers / lists, and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state.

[0230] For example, in one instance, if the triggering information signaling includes one or more SRS resource sets and / or SRS resource identifiers / lists (i.e., the triggering information signaling includes at least one SRS resource set and / or SRS resource identifier), and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the SRS resource set corresponding to the SRS and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state, while the UL Tx spatial filter for transmitting other SRS resource sets / SRS resources can be determined based on the TCI state. Alternatively, if the triggering information signaling includes one or more SRS resource sets and / or SRS resource identifiers / lists, and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the SRS resource set corresponding to the SRS and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state, while the UL Tx spatial filter for transmitting other SRS resource sets / SRS resources is not determined based on the TCI state.

[0231] Method 5: The target information is SRS resource configuration information, meaning the SRS resource configuration information includes this indication information, for example, in the SRS-Resource IE or in the configuration information within the SRS-Resource IE:

[0232] For example, in one example, there is a parameter that includes the indication information. This example is similar to the method in method 1 that includes the parameter corresponding to the indication information. The difference is that in method 5, the parameter that includes the indication information is SRS resource configuration information, while in method 1, the parameter that includes the indication information is TCI configuration information. This will not be elaborated further.

[0233] For example, in one instance, if the SRS resource configuration information includes one or more TCI state identifiers / lists (i.e., the SRS resource configuration information includes at least one TCI state identifier), and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state. Alternatively, if the SRS resource configuration information includes one or more TCI state identifiers / lists, and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state.

[0234] Method 6: The target information is the SRS resource set configuration information, that is, the SRS resource set configuration information includes this indication information, for example, in the SRS-ResourceSet IE or in the configuration information of the SRS-ResourceSet IE:

[0235] For example, in one example, there is a parameter that includes the indication information. This example is similar to the method in Method 1 that includes the parameter corresponding to the indication information. The difference is that in Method 6, the SRS resource set configuration information includes the parameter that includes the indication information, while in Method 1, the TCI configuration information includes the parameter that includes the indication information. This will not be elaborated further.

[0236] For example, in one instance, if the SRS resource set configuration information includes one or more TCI state identifiers / lists (i.e., the SRS resource set configuration information includes at least one TCI state identifier), and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the ULTx spatial filter for transmitting the SRS is not determined based on the TCI state; for other TCI states, the ULTx spatial filter for transmitting the SRS is determined based on the TCI state. Alternatively, if the SRS resource set configuration information includes one or more TCI state identifiers / lists, and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the ULTx spatial filter for transmitting the SRS is determined based on the TCI state; for other TCI states, the ULTx spatial filter for transmitting the SRS is not determined based on the TCI state.

[0237] Method 7: The target information is SRS configuration information, that is, the SRS configuration information includes this indication information:

[0238] For example, in one example, there are parameters that include indication information. This example is similar to the method in Method 1 that includes the parameters corresponding to the indication information. The difference is that in Method 7, it is SRS configuration information, while in Method 1, it is TCI configuration information including the parameters of the indication information. This will not be elaborated further.

[0239] For example, in one instance, if the SRS configuration information includes one or more TCI state identifiers / lists (i.e., the SRS configuration information includes at least one TCI state identifier), and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state. Alternatively, if the SRS configuration information includes one or more TCI state identifiers / lists, and the TCI state corresponding to one or more TCI state identifiers / lists includes the TCI state corresponding to the SRS, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state; for other TCI states, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state.

[0240] For example, in one instance, if the SRS configuration information includes one or more SRS resource sets and / or SRS resource identifiers / lists (i.e., the SRS configuration information includes at least one SRS resource set and / or SRS resource identifier), and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is not determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources can be determined based on the TCI state. Alternatively, if the SRS configuration information includes one or more SRS resource sets and / or SRS resource identifiers / lists, and the SRS resource set / SRS resource corresponding to the identifier / list includes the identifier of the corresponding SRS resource set and / or the identifier of the SRS resource, the UL Tx spatial filter for transmitting the SRS is determined based on the TCI state, while the UL Tx spatial filter for other SRS resource sets / SRS resources is not determined based on the TCI state.

[0241] Additionally, it should be noted that the method for determining whether to determine the uplink transmission spatial filter based on the TCI state when the target information is B8: bandwidth portion BWP configuration information, B9: carrier configuration information, or B10: cell configuration information is similar to the method for determining whether to determine the uplink transmission spatial filter based on the TCI state when the target information is TCI state configuration information. The difference lies in the different target information, which will not be elaborated further.

[0242] In some embodiments, the triggering information signaling includes at least one of the following:

[0243] The downlink control information DCI signaling or MAC-CE signaling of the SRS resource set or SRS resources corresponding to the uplink signal is scheduled or activated;

[0244] The configuration signaling corresponding to the SRS resource set or the trigger state associated with the SRS resource;

[0245] Signaling to schedule or activate uplink signals.

[0246] That is, the triggering information signaling may include at least one of the following: DCI signaling or MAC-CE signaling for the SRS resource set / SRS resource corresponding to the scheduling / activation of the SRS; configuration signaling corresponding to the triggering state associated with the SRS resource set or SRS resource corresponding to the uplink signal (e.g., in aperiodicSRS-ResourceTrigger); and signaling for scheduling / activating the uplink signal.

[0247] In some embodiments, the TCI state corresponding to the uplink signal is a TCI state used to determine the transmission power of the uplink signal. For example, the UE determines the transmission power of the uplink signal based on uplink power control parameters included or associated with the TCI state.

[0248] In some embodiments, the TCI state corresponding to the uplink signal includes at least one of the following:

[0249] The TCI status associated with the SRS resource corresponding to the uplink signal;

[0250] The TCI status associated with the SRS resource set corresponding to the uplink signal;

[0251] The TCI status associated with the target SRS resource in the SRS resource set corresponding to the uplink signal.

[0252] In some embodiments, determining the Transmission Configuration Indicator (TCI) state corresponding to the uplink signal includes:

[0253] The terminal device receives target signaling sent by the network device, which is used to indicate the TCI status. That is, the network device can indicate the TCI status through target signaling, and the terminal device determines the TCI status indicated by the target signaling as the TCI status corresponding to the uplink signal.

[0254] In some embodiments, the target signaling includes at least one of the following:

[0255] Radio Resource Control (RRC) signaling;

[0256] MAC-CE signaling;

[0257] DCI signaling.

[0258] For example, taking the uplink signal as SRS as an example, the TCI state corresponding to the above uplink signal is explained in detail:

[0259] For the TCI state associated with the SRS resource corresponding to the SRS:

[0260] For example, the TCI state indicated by the network device for the SRS resource via one or more of the following: RRC parameters, MAC-CE signaling, and DCI signaling;

[0261] For example, the TCI state indicated by the network device for the SRS resource via RRC parameters;

[0262] For example, the TCI state indicated by the network device for the SRS resource via MAC-CE signaling;

[0263] For example, the TCI state indicated by the network device for the SRS resource via DCI signaling;

[0264] For example, multiple TCI states can be configured for the SRS resource by the network device through RRC parameters, and then one or more TCI states can be selected from them through MAC-CE signaling;

[0265] For example, multiple TCI states can be configured for the SRS resource by the network device through RRC parameters, multiple TCI states can be selected from them through MAC-CE signaling, and one TCI state can be selected from them through DCI signaling;

[0266] For example, configure the network device to associate the SRS resource with one of the multiple valid TCI states indicated by the network device via RRC parameters, and then determine the TCI state associated with the SRS resource based on one or more of the valid TCI states indicated by the network device via RRC parameters, MAC-CE signaling, and DCI signaling.

[0267] In one example, the TCI state associated with the SRS resource is the TCI state used to determine power control parameters and / or the UL Tx spatial filter.

[0268] For the TCI state associated with the SRS resource set corresponding to the SRS:

[0269] For example, the TCI state associated with the SRS resource set and applicable to all SRS resources in the SRS resource set.

[0270] For example, the TCI state indicated by the network device for the SRS resource set via one or more of RRC parameters, MAC-CE signaling, and DCI signaling;

[0271] For example, the TCI state indicated by the network device for this SRS resource set via RRC parameters;

[0272] For example, the TCI state indicated by the network device for the SRS resource set via MAC-CE signaling;

[0273] For example, the TCI state indicated by the network device for the SRS resource set via DCI signaling;

[0274] For example, multiple TCI states can be configured for the SRS resource set by the network device through RRC parameters, and then one or more TCI states can be selected from them through MAC-CE signaling;

[0275] For example, multiple TCI states can be configured for the SRS resource set by the network device through RRC parameters, multiple TCI states can be selected from them through MAC-CE signaling, and one TCI state can be selected from them through DCI signaling;

[0276] For example, configure the network device with respect to which of the multiple valid TCI states indicated by the network device for the SRS resource set via RRC parameters, and then determine the TCI state associated with the SRS resource set based on the valid TCI states indicated by the network device via one or more of RRC parameters, MAC-CE signaling, and DCI signaling.

[0277] For example, the TCI state associated with the SRS resource set is the TCI state used to determine power control parameters and / or UL Txspatial filter.

[0278] For example, a TCIstate associated with a specific SRS resource (i.e., the target SRS resource) in the SRS resource set;

[0279] Examples of specific SRS resources:

[0280] The SRS resource with the smallest ID;

[0281] The SRS resource with the largest ID;

[0282] SRS resources indicated by the network device;

[0283] The SRS resource with the smallest sequence number;

[0284] The SRS resource with the largest serial number.

[0285] The method by which a network device indicates the associated TCI state for a specific SRS resource can be referred to the previous method for indicating the associated TCI state for an SRS resource, and will not be repeated here.

[0286] In this embodiment of the application, by way of example, the TCI state corresponding to the SRS is the TCI state used to determine the power control parameters for transmitting the SRS.

[0287] In some embodiments, determining the uplink transmission spatial filter based on the TCI state may include: determining the uplink transmission spatial filter based on the reference signal associated with the TCI state.

[0288] For the reference signal associated with the TCI state:

[0289] For example, in one example, it could be a reference signal configured in the TCI state configuration information.

[0290] For example, the reference signal in TCI-UL-state IE (e.g., referenceSignal).

[0291] For example, in the QCL information qcl-Type2 and qcl-Type1 of TCI-state IE, the reference signal (e.g., referenceSignal) in the QCL information is configured as typeD.

[0292] For example, the reference signal associated with the TCI state is the default reference signal. For example, it could be the SSB signal, or NZP-CSI-RS, or Msg3 PUSCH, or the PUSCH of a RAR grant, etc.

[0293] In some embodiments, the method for determining the uplink transmit spatial filter based on the reference signal associated with the TCI state may include any of the following:

[0294] If the reference signal is a downlink (DL) RS, then the spatial filter of the UE receiving the reference signal is used as the spatial transmission filter for transmitting the SRS.

[0295] If the reference signal is UL RS, then the SRS is transmitted using the same spatial transmission filter (UL Txspatial filter) that transmits the reference signal.

[0296] In one example, the type of reference signal may include: NZP-CSI-RS, TRS, SSB (SS / PBCH block), SRS, etc. Optionally, SRS is an SRS with usage for beam management. Optionally, NZP-CSI-RS is a CSI-RS used for beam management, for example, configured with the higher-layer parameter repetition.

[0297] In some embodiments, the method further includes:

[0298] The path loss of the uplink signal is determined based on the power control parameters corresponding to the TCI state.

[0299] In this way, the terminal device can always determine the power control parameters corresponding to the SRS transmission based on the TCI state, and can also automatically select the appropriate transmission beam for the SRS transmission (sending a spatial filter to Cinderella). Thus, while meeting the beam management requirements, the terminal device and network device do not need to maintain multiple sets of methods for determining the power control parameters corresponding to the SRS resources, reducing the complexity of the UE and network device.

[0300] In some embodiments, the power control parameters include at least one of the following:

[0301] Road loss offset indicator;

[0302] Road loss offset configuration identifier;

[0303] Road loss offset configuration;

[0304] Road loss offset value;

[0305] Road damage.

[0306] For example, in one example, the power control parameters corresponding to the TCI state can be power parameters configured in the TCI state configuration information. These could include path loss reference signal identifier, path loss offset identifier, path loss offset value, path loss offset configuration identifier, path loss offset configuration, path loss offset value, path loss, and uplink power control parameters (ul-powerControl). It should be noted that the path loss offset identifier can be used to uniquely identify the path loss offset value, the path loss offset configuration identifier can be used to uniquely identify the path loss offset configuration, and the path loss offset configuration corresponds to path loss offset information (e.g., including but not limited to path loss offset values). Path loss can be determined through the path loss offset information corresponding to the path loss offset configuration.

[0307] Optionally, the uplink power control parameters may include at least one of the following: target power value (p0, i.e., target power value), path loss compensation factor (alpha, i.e., α), closed loop index (closedLoopIndex). This configuration information may be one or more of RRC signaling and MAC-CE signaling. In one example, the power control parameters corresponding to the TCI state may be configured in the information activating the TCI state, for example, in the MAC-CE activating the TCI state. In one example, the power control parameters corresponding to the TCI state may be indicated by MAC-CE signaling / DCI signaling that indicates / updates the power control parameters associated with the TCI state. Exemplarily, the aforementioned power parameters include one or more of the following: information indicating a path loss reference signal (e.g., an identifier), information indicating the target power p0, information indicating alpha (i.e., path loss compensation factor α), information indicating the closed loop power control parameter closedLoopIndex, information indicating the path loss offset value, etc. Optionally, the path loss offset value is used to indicate the offset between uplink and downlink path losses, or to indicate the path loss offset between two UL transmissions. The closed-loop power control parameter closedLoopIndex can be used to determine the closed-loop power control adjustment status.

[0308] In this embodiment, the path loss of the uplink signal can be determined based on at least one of the following parameters: path loss offset identifier corresponding to the TCI state, path loss offset configuration identifier, path loss offset configuration, path loss offset value, and path loss, so as to improve the flexibility of path loss determination.

[0309] In some embodiments, determining the path loss of the uplink signal based on the power control parameters corresponding to the TCI state includes:

[0310] Determine the power control parameters corresponding to the TCI state associated with the target SRS resource, and determine the path loss of the uplink signal based on the power control parameters. The target SRS resource is the SRS resource in the SRS resource set where the SRS resource corresponding to the uplink signal is located.

[0311] In related technologies, network devices typically determine UL / DL scheduling and other information based on all SRS resources within an SRS resource set. For example, they select appropriate beam directions and precoding matrices with good UL / DL transmission performance. However, if at least two SRS resources in an SRS resource set are configured with different TCI states, determining the path loss for each SRS resource based on its respective TCI state's associated path loss offset could lead to different path loss calculations for different SRS resources. This results in varying transmission power across different SRS resources within the same SRS resource set, making it difficult for the network device to determine suitable UL / DL scheduling information and thus reducing transmission performance. In this embodiment, the power control parameters corresponding to the TCI state of the target SRS resource in the SRS resource set where the uplink signal is located are determined. The path loss of the uplink signal is determined based on the power control parameters, which ensures that all SRS resources in the same SRS resource set use the same power control parameters. This allows the base station to more effectively measure the differences between multiple SRS resources in the same SRS resource set, thereby better performing UL / DL scheduling and effectively improving system performance.

[0312] In one example, during the process of determining path loss based on the path loss offset value, the first downlink path loss (DL PL, for example, denoted as PL) can be determined based on the downlink path loss reference signal. DL Then, based on DL PL and path loss offset values ​​(e.g., denoted as PL), offset The first uplink path loss (UL PL, for example, can be represented as PL) is determined. UL PL UL For PL DL and PL offset (the difference).

[0313] Another example is: in determining path loss based on path loss offset, an initial UL PL (i.e., the initial uplink path loss) can be determined first based on the downlink path loss reference signal, for example, denoted as PL. UL-inital Then, based on the previous ULPL and road loss offset value, the current ULPL is determined (for example, the previous ULPL is represented as PL). UL-before The current UL road loss PL UL For PL UL-before and PL offset The difference). Before the UE receives the path loss offset value sent by the network device, UL PL equals PL. UL-inital Some examples of the aforementioned UL PL include: receiving PL for the UE. offsetPreviously, the UL PL corresponding to the TCI state of the UL transmission, or the PL received by the UE. offset Before it takes effect, the UL PL corresponding to the TCIstate corresponding to this UL transmission.

[0314] In some embodiments, the target SRS resource is at least one of the following in the SRS resource set containing the SRS resource corresponding to the uplink signal:

[0315] The SRS resource with the smallest identifier (ID);

[0316] The SRS resource with the largest ID;

[0317] SRS resources indicated by the network device;

[0318] The SRS resource with the smallest sequence number;

[0319] The SRS resource with the largest serial number.

[0320] It should be understood that the path loss of the uplink signal can be determined based on the power control parameters corresponding to the TCI state associated with the target SRS resource. The target SRS resource is an SRS resource in the SRS resource set containing the SRS resource corresponding to the uplink signal. That is, the path loss can be determined by selecting the power control parameters corresponding to the TCI state of a specific SRS resource within this SRS resource set. For example, each SRS resource has a corresponding ID, which uniquely indicates the SRS resource. The SRS resource with the smallest ID or the SRSI resource with the largest ID in the SRS resource set can be selected as the target SRS resource. Alternatively, the network device can indicate the target SRS resource by sending resource indication information. After receiving this resource indication information, the terminal device can determine the target SRS resource. Another example is the sequence number corresponding to each SRS resource; the SRS resource with the smallest sequence number or the SRSI resource with the largest sequence number in the SRS resource set can be selected as the target SRS resource.

[0321] In this implementation, at least one of the following can be selected as the target SRS resource: the SRS resource with the smallest ID, the SRS resource with the largest ID, the SRS resource indicated by the network device, the SRS resource with the smallest sequence number, and the SRS resource with the largest sequence number from the SRS resource set where the uplink signal is located. This can improve the flexibility of selecting the target SRS resource.

[0322] In some embodiments, the method further includes:

[0323] The uplink signal transmission power is determined based on the uplink signal path loss.

[0324] It should be noted that there are multiple ways to determine the uplink signal transmission power based on the path loss of the uplink signal, and no specific limitation is made. For example, calculations can be performed using formulas in relevant technologies (e.g., relevant protocols / specifications), which will not be elaborated further. After determining the transmission power, the uplink signal can be transmitted based on the transmission power.
