Power control methods and equipment

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 201910631595.3, filed in China on July 12, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to a power control method and device. Background Technology

[0004] In Rel-15, network devices use the Sounding Reference Signal (SRS) Resource Indicator (SRI) field in the Downlink Control Information (DCI) to instruct terminal devices on the power control parameters used to transmit the Physical Uplink Shared Channel (PUSCH). The SRI field in the DCI corresponds to an SRS resource, which includes spatially relevant information indicating the transmit beam of the PUSCH. The SRI also indicates the PUSCH power control parameters, which the terminal device can use to determine the PUSCH transmit power.

[0005] Typically, different beams have different path losses and corresponding transmission powers. If spatially relevant information changes, network equipment may need to reconfigure power control parameters for terminal devices.

[0006] However, if the network device fails to reconfigure the power control parameters to the terminal device in a timely manner, the terminal device will continue to use the previously configured power control parameters to send PUSCH. This will cause the terminal device to send PUSCH with inaccurate power, which in turn will cause the PUSCH to interfere with or limit the coverage of other terminal devices.

[0007] Summary of the Invention

[0008] This disclosure provides a power control method and apparatus to solve the problem that the transmission power determined by the terminal device is inaccurate because the network device fails to adjust the power control parameters in a timely manner according to beam changes.

[0009] To solve the above-mentioned technical problems, this disclosure is implemented as follows:

[0010] In a first aspect, embodiments of this disclosure provide a power control method applied to a terminal device. The method includes: receiving configuration information from a network device, the configuration information being used to indicate target space-related information of target uplink data; determining the transmission power of the target uplink data based on the target space-related information; wherein the target space-related information includes at least one of the following: M power control parameters, target power control parameters corresponding to the target space-related information, and information indicating the target power control parameters; M is a positive integer; the target uplink data includes: SRS or PUSCH.

[0011] Secondly, embodiments of this disclosure provide a power control method applied to a network device. The method includes: sending configuration information to a terminal device, the configuration information being used to indicate target space-related information of target uplink data; wherein the target space-related information includes at least one of the following: M power control parameters, target power control parameters, and information used to indicate the target power control parameters; M is a positive integer; the target uplink data includes: SRS or PUSCH.

[0012] Thirdly, embodiments of this disclosure provide a terminal device, which includes: a receiving module, configured to receive configuration information from a network device, the configuration information being used to indicate target space-related information of target uplink data; and a determining module, configured to determine the transmission power of the target uplink data based on the target space-related information; wherein the target space-related information includes at least one of the following: M power control parameters, target power control parameters corresponding to the target space-related information, and information indicating the target power control parameters; M is a positive integer; and the target uplink data includes: SRS or PUSCH.

[0013] Fourthly, embodiments of this disclosure provide a network device, which includes: a transmitting module, configured to transmit configuration information to a terminal device, the configuration information being used to indicate target space-related information of target uplink data; wherein the target space-related information includes at least one of the following: M power control parameters, target power control parameters, information used to indicate the target power control parameters; M is a positive integer; the target uplink data includes: SRS or PUSCH.

[0014] Fifthly, embodiments of this disclosure provide a terminal device including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the power control method as described in the first aspect.

[0015] In a sixth aspect, embodiments of this disclosure provide a network device including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the power control method as described in the second aspect.

[0016] In a seventh aspect, embodiments of this disclosure provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the power control method described above.

[0017] In this embodiment, the network device can send configuration information to the terminal device. This configuration information is used to indicate the target spatial information related to the target uplink data. The terminal device can determine the transmission power of the target uplink data based on the target spatial information. Compared with traditional uplink transmission, when the spatial information changes, if the target spatial information includes at least one of the following: M power control parameters, the target power control parameters corresponding to the target spatial information, and information indicating the target power control parameters, then there is no need to wait for the network device to reconfigure the power control parameters. The terminal device can directly obtain or find the target power control parameters based on the target spatial information indicated by the configuration information. This allows the terminal to use accurate power control parameters to control the power of the target uplink data. This not only avoids the terminal device using inaccurate power to send the target uplink data (i.e., SRS or PUSCH), but also avoids the signaling configuration overhead and latency caused by reconfiguring the power control parameters.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] The technical solution provided in this application will be described below with reference to the accompanying drawings.

[0032] The technical solutions provided in this disclosure can be applied to various communication systems, such as 5G communication systems, future evolution systems, or multiple communication convergence systems. They can include various application scenarios, such as machine-to-machine (M2M), direct-to-machine (D2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine-type communication (mMTC). These scenarios include, but are not limited to, communication between terminal devices, communication between network devices, and communication between network devices and terminal devices. The embodiments of this disclosure can be applied to communication between network devices and terminal devices, or between terminal devices and terminal devices, or between network devices in 5G communication systems.

[0033] Figure 1 illustrates a possible structural diagram of a communication system according to an embodiment of this disclosure. As shown in Figure 1, the communication system includes at least one network device 100 (only one is shown in Figure 1) and one or more terminal devices 200 connected to each network device 100.

[0034] The network device 100 mentioned above can be a base station, core network equipment, transmission and reception point (TRP), relay station, or access point, etc. The network device 100 can be a base transceiver station (BTS) in a Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA) network, an NB (NodeB) in Wideband Code Division Multiple Access (WCDMA), or an eNB or eNodeB (evolutionary NodeB) in LTE. The network device 100 can also be a radio controller in a Cloud Radio Access Network (CRAN) scenario. The network device 100 can also be a network device in a 5G communication system or a network device in a future evolved network. However, the terminology used does not constitute a limitation of this disclosure.

[0035] Terminal device 200 can be a wireless terminal device or a wired terminal device. The wireless terminal device can be a device that provides voice and / or other service data connectivity to the user, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc. Wireless terminal equipment can communicate with one or more core networks via a Radio Access Network (RAN). Wireless terminal equipment can be mobile terminal equipment, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices. They exchange voice and / or data with the RAN, and include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), etc. Wireless terminal equipment can also be mobile devices, User Equipment (UE), UE terminal equipment, access terminal equipment, wireless communication equipment, terminal equipment units, terminal equipment stations, mobile stations, mobile stations, remote stations, remote terminals, subscriber units, subscriber stations, and user agents. Agent), terminal device, etc. As an example, in this embodiment of the disclosure, Figure 1 shows a mobile phone as the terminal device.

[0036] In current uplink transmissions, if network devices fail to reconfigure power control parameters for terminal devices in a timely manner, the terminal devices will continue to use the previously configured power control parameters to transmit SRS or PUSCH. This leads to the terminal devices transmitting SRS or PUSCH with inaccurate power, which in turn causes interference or transmission failure to other terminal devices. Network devices can configure SRS power control parameters via Radio Resource Control (RRC) signaling. This can be done using SRS resource sets, where each resource set can include an indication of an SRS resource. Each SRS resource contains spatial information related to the transmission beam of the SRS.

[0037] To address the aforementioned issues, network devices can send configuration information to terminal devices. This configuration information indicates target spatial information related to the target uplink data. The terminal device can then determine the transmission power of the target uplink data based on this spatial information. Compared to traditional uplink transmission, when spatial information changes, if the target spatial information includes at least one of the following: M power control parameters, the target power control parameters corresponding to the target spatial information, and information indicating the target power control parameters; where M is a positive integer, then there is no need to wait for the network device to reconfigure the power control parameters. The terminal device can directly obtain or find the target power control parameters based on the target spatial information indicated by the configuration information. This allows the terminal to use accurate power control parameters to control the power of the target uplink data, avoiding not only the terminal device sending the target uplink data with inaccurate power (i.e., SRS or PUSCH) but also avoiding the signaling configuration overhead and latency caused by reconfiguring the power control parameters.

[0038] Figure 2 illustrates an interactive flow diagram of a power control method provided in an embodiment of this disclosure. As shown in Figure 2, the power control method provided in this embodiment may include the following steps 201 to 203:

[0039] Step 201: The network device sends configuration information to the terminal device.

[0040] Step 202: The terminal device receives configuration information from the network device.

[0041] The configuration information described above indicates the target space-related information of the target uplink data, which corresponds to the target power control parameters. The target uplink data includes SRS or PUSCH.

[0042] Optionally, the aforementioned target space-related information includes at least one of the following: M power control parameters, target power control parameters corresponding to the target space-related information, and information used to indicate the target power control parameters.

[0043] For example, the target space-related information mentioned above carries a first identifier, that is, the information used to indicate the target power control parameter is the first identifier. The first identifier is used to indicate the target power control parameter, and the terminal device can determine the target power control parameter indicated by the first identifier from M power control parameters according to the first identifier.

[0044] For example, when the target space-related information includes M power control parameters, the aforementioned information for indicating the target power control parameters may be configured by the network device to the terminal device through other configuration information or signaling.

[0045] For example, when the target-related information includes M power control parameters, the terminal device can determine the target power control parameter from the M power control parameters according to a predetermined rule. The aforementioned target rule can be configured by the network device or can be predefined.

[0046] For example, the target power control parameter mentioned above can be at least one of M power control parameters, where M is a positive integer. Each power control parameter corresponds to one beam.

[0047] In one example, where the target space-related information includes M power control parameters and information indicating the target power control parameters, the target power control parameters are at least one of the M power control parameters.

[0048] For example, the configuration information described above is used to indicate M power control parameters. Example a: The configuration information described above includes target space-related information and M power control parameters. Example b: The configuration information described above includes target space-related information, which in turn includes M power control parameters.

[0049] For example, the configuration information described above is used to indicate target power control parameters. Example c: The configuration information described above includes target space-related information and target power control parameters. Example d: The configuration information described above includes target space-related information, which in turn includes target power control parameters.

[0050] For example, the M power control parameters mentioned above are pre-configured by the network device for the terminal device, or predefined, or specified by the protocol. For instance, the M power control parameters mentioned above may be pre-configured by the network device before sending configuration information.

[0051] In one example, after obtaining information indicating the target power control parameter, the terminal device determines the target power control parameter from M power control parameters based on the information indicating the target power control parameter.

[0052] It is understandable that after the terminal device obtains the target space information, when the space information changes, it can determine the target power control parameter indicated by the target space information from the pre-configured M power control parameters based on the target space information. This avoids the delay caused by re-receiving the power control parameters configured by the network device, and eliminates the need for the network device to send the reconfigured power control parameters to the terminal device, thus eliminating the need for additional configuration signaling by the network device.

[0053] For example, target spatial information can also be used to indicate the transmission beam of the aforementioned target uplink data. For instance, taking the transmission of SRS as an example, spatial information 1 indicates that the transmission beam of the SRS is beam 1, and spatial information 2 indicates that the transmission beam of the SRS is beam 2.

[0054] Optionally, the above configuration information used to indicate target space-related information of the target uplink data can be either: the configuration information includes target space-related information, or the configuration information carries an identifier indicating target space-related information.

[0055] In one example, the terminal device may pre-store at least one space-related information, and the configuration information carrying an identifier indicating the target space-related information may indicate the target space-related information in the at least one space-related information.

[0056] Step 203: The terminal device determines the uplink data transmission power of the target based on the target space-related information.

[0057] It should be noted that the above configuration information can be used to configure the network device to transmit target uplink data to the terminal device, or it can be used to configure the network device to switch transmission beams for the terminal device. Switching transmission beams can be: switching from the first beam transmitting SRS to the second beam transmitting SRS; or switching transmission beams can be: switching from the first beam transmitting PUSCH to the second beam transmitting PUSCH.

[0058] In one example, after receiving the configuration information, the terminal device can first determine the target space-related information from the configuration information, and then determine the transmission beam indicated by the target space-related information and the target power control parameters corresponding to the target uplink data based on the target space-related information.

[0059] The power control method provided in this disclosure allows a network device to send configuration information to a terminal device. This configuration information indicates target spatial information related to the target uplink data. The terminal device can determine the transmission power of the target uplink data based on the target spatial information. Compared to traditional uplink transmission, when spatial information changes, if the target spatial information includes at least one of the following: M power control parameters, the target power control parameters corresponding to the target spatial information, and information indicating the target power control parameters; where M is a positive integer, then there is no need to wait for the network device to reconfigure the power control parameters. The terminal device can directly obtain or find the target power control parameters based on the target spatial information indicated by the configuration information. This allows the terminal to use accurate power control parameters to control the power of the target uplink data. This not only avoids the terminal device sending the target uplink data (i.e., SRS or PUSCH) with inaccurate power, but also avoids the signaling configuration overhead and latency caused by reconfiguring the power control parameters.

[0060] Optionally, the target space-related information includes at least one of the following: an SRS power control parameter set, an identifier for the SRS power control parameter set; a PUSCH power control parameter set, a PUSCH power control parameter identifier set, and a target SRS resource identifier (SRI). The SRS power control parameter set includes target power control parameters, which are power control parameters for transmitting SRS. The PUSCH power control parameter set includes target power control parameters, which are power control parameters for transmitting PUSCH. The PUSCH power control parameter identifier set includes identifiers for target power control parameters, which are power control parameters for transmitting PUSCH. The target SRI is used to indicate the PUSCH power control parameter identifier set.

[0061] Typically, any power control parameter includes at least one of the following: the network device's preset received power (P0), path loss compensation factor (alpha), path loss calculation reference signal (PathlossReferenceRS), and closed-loop power control process (CloseloopProcess).

[0062] For example, when transmitting SRS, the preset receiving power is the preset receiving power of the network device when receiving SRS, and when transmitting PUSCH, the preset receiving power is the preset receiving power of the network device when receiving PUSCH.

[0063] Understandably, the terminal device can calculate the path loss based on the path loss calculation reference signal, and then calculate the transmission power according to other power control parameters.

[0064] For example, Figure 3 is a schematic diagram of an SRS resource provided in an embodiment of this disclosure. As shown in Figure 3(a), the spatially related information in the SRS resource includes a power control parameter set, which is {P0, alpha, PathlossReferenceRS, CloseloopProcess}. When the spatially related information corresponding to the SRS resource is the spatially related information of PUSCH, the power control parameter set is the PUSCH power control parameter set; when the spatially related information corresponding to the SRS resource is the spatially related information of SRS, the power control parameter set is the SRS power control parameter set.

[0065] For ease of explanation, the examples in this disclosure use the following as examples: the power control parameters include the network device's preset received power (P0), the path loss compensation factor (alpha), the path loss calculation reference signal (PathlossReferenceRS), and the closed-loop power control process. These will not be elaborated upon further below.

[0066] Optionally, in this embodiment of the disclosure, when the target uplink data is SRS, the target space-related information includes at least one of the following: a set of SRS power control parameters and an identifier of the set of SRS power control parameters.

[0067] For example, target space-related information may be SRS resource set information configured for network devices, which includes at least one of the following: an SRS power control parameter set and an identifier for the SRS power control parameter set.

[0068] Each SRS resource in the SRS resource set may include space-related information, and the space-related information is configured with a set of power control parameters.

[0069] Optionally, in this embodiment of the disclosure, when the target uplink data is PUSCH, the target space-related information includes at least one of the following: a set of PUSCH power control parameters, a set of PUSCH power control parameter identifiers, and a target SRS resource indicator (SRI).

[0070] For example, the target space-related information can be SRS space-related information configured for the network device, which includes at least one of the following: a set of PUSCH power control parameters, a set of PUSCH power control parameter identifiers, and a target SRS resource identifier (SRI).

[0071] For example, referring to Figure 4, the PUSCH power parameter identifier set may include {P0 identifier, alpha identifier, PathlossReferenceRS identifier, CloseloopProcess identifier}. Spatial information in the SRS resource may include SRIs (e.g., target SRIs), which correspond to a set of power control parameter identifiers associated with that SRI in the PUSCH resource. For example, the PUSCH resource includes set 1 and set 2, with SRI1 corresponding to set 1 and SRI2 corresponding to set 2. Set 1 includes {P0 set 1, alpha set 1, PathlossReferenceRS1, CloseloopProcess1}, and set 2 includes {P0 set 2, alpha set 2, PathlossReferenceRS2, CloseloopProcess2}.

[0072] Optionally, if the target power control parameter is at least one of the M power control parameters pre-configured by the network device for the terminal device, the power control method provided in this embodiment of the present disclosure further includes steps 204a and 204b before step 201.

[0073] Step 204a: The network device sends M power control parameters to the terminal device.

[0074] Step 204b: The terminal device receives M power control parameters from the network device.

[0075] Optionally, in this embodiment of the disclosure, before step 201, the power control method provided in this embodiment of the disclosure further includes steps 205a and 205b.

[0076] Step 205a: The network device sends N spatial information to the terminal device.

[0077] The N spatially related information can be used to indicate the aforementioned M power control parameters, where N is a positive integer.

[0078] Step 205b: The terminal device receives N spatial information from the network device.

[0079] Optionally, the network device can send the above N spatial information items to the terminal device via RRC signaling.

[0080] Based on this scheme, before the network device sends configuration information to the terminal device, the network device can send the aforementioned M power control parameters to the terminal device by sending N spatially related information to the terminal device. This allows the terminal device to quickly determine the target power control parameters from the M power control parameters indicated by the N spatially related information sent in advance by the network device after receiving the configuration information.

[0081] Optionally, in this embodiment of the disclosure, the configuration information described above is used to indicate at least one SRS resource, and the at least one SRS resource contains target space-related information; wherein, the configuration information described above is carried on the target MAC CE (MAC CE is the control unit of the media access layer), and the at least one SRS resource is the SRS resource corresponding to the target MAC CE; and / or, the configuration information described above includes a resource indicator (SRI) of at least one SRS resource.

[0082] It is understood that when the configuration information is used to indicate a resource set (including at least one SRS resource), each SRS resource in the SRS resource set contains space-related information, the SRS resource set includes target space-related information, and the target SRS resource in the SRS resource set may carry an SRS power control parameter set and / or an identifier of the SRS power control parameter set, that is, the target SRS resource contains target space-related information.

[0083] Referring to Figure 3(c), the SRS resource set includes at least one SRS resource (the figure uses one SRS resource as an example for illustration). The SRS space-related information in this SRS resource includes: P0 set identifier, alpha set identifier, PathlossReferenceRS identifier, and CloseloopProcess identifier.

[0084] Assuming that before step 201, the terminal device performs uplink transmission on the first beam, the uplink transmission on the first beam can be either PUSCH transmission or SRS transmission.

[0085] Optionally, if the transmission beam indicated in the target space-related information becomes the second beam, and if the second beam is different from the first beam, the terminal device can determine the transmission power of the target uplink data on the second beam according to the target power control parameters indicated in the target space-related information.

[0086] Example 1: The first MAC CE is the MAC CE that carries the first configuration information before receiving the configuration information. The first MAC CE corresponds to the first SRS resource. The second MAC CE is the MAC CE that carries the above configuration information. The second MAC CE corresponds to the second SRS resource. The first SRS resource includes first spatial related information, which includes {P01, alpha1, PathlossReferenceRS1, CloseloopProcess1}. The second SRS resource includes second spatial related information, which includes {P02, alpha2, PathlossReferenceRS2, CloseloopProcess2}. The first configuration information is used to configure the terminal device to determine the power using the power control parameters indicated by the first spatial related information.

[0087] In the case of transmitting SRS, when the beam indication changes from the first MAC CE to the second MAC CE, the terminal device can determine that the power control parameters corresponding to the spatial information in the second SRS resource corresponding to the second MAC CE are the target power control parameters.

[0088] Example 2: The first SRI is the SRS resource indication for PUSCH transmitted before receiving the above configuration information, and the second SRI is the SRS resource indication for PUSCH transmitted in the above configuration information. The first SRI corresponds to the first SRS resource, which includes first spatial information, and the first spatial information includes the first SRI. The second SRI corresponds to the second SRS resource, which includes second spatial information, and the second spatial information includes the second SRI. The PUSCH resource includes a first set and a second set. The first set is PUSCH power control parameter identifier set 1, and the second set is PUSCH power control parameter identifier set 2. The power control parameters in set 1 include: {P01, alpha1, PathlossReferenceRS1, CloseloopProcess1}, and the power control parameters in set 2 include: {P02, alpha2, PathlossReferenceRS2, CloseloopProcess2}.

[0089] When the PUSCH beam indication changes from the first SRI to the second SRI, the terminal device can determine that the power control parameters in set 2 corresponding to the second SRI are the target power control parameters for transmitting the PUSCH.

[0090] Based on this scheme, the configuration information is used to indicate at least one SRS resource, which contains target space related information. When the terminal device determines that the MAC CE carrying the above configuration information has changed from the MAC CE of the first configuration information before receiving the configuration information, or determines that the SRI of the above configuration information has changed from the SRI carried in the configuration information before receiving the first configuration information, the power control parameters indicated in the at least one SRS resource containing target space related information can be indicated according to the above configuration information.

[0091] Optionally, in the embodiments of this disclosure, any power control parameter includes at least one of the following: the preset received power of the network device, the path loss compensation factor, the path loss calculation reference signal, and the closed-loop power control process; wherein, when the target space related information includes the target signal, the target signal is the path loss calculation reference signal.

[0092] The target signal may include a Synchronization Signal Block (SSB) or Channel State Information-Reference Signals (CSI-RS). An SSB is composed of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

[0093] As shown in Figure 3(b), spatial information in SRS resources may include SSB identifiers and CSI-RS identifiers.

[0094] Typically, if the target space-related information includes the target signal, the target power control parameters corresponding to the target space-related information can be configured with a road loss calculation reference signal, or they can be left unconfigured.

[0095] Example 4: If the target space-related information indicates the transmission of PUSCH, and the target space-related information includes SSB, the SSB can be used as a reference signal for path loss calculation to calculate the transmission power of PUSCH.

[0096] Example 5: If the target space-related information indicates the transmission of SRS, and the target space-related information includes SSB, the SSB can be used as a reference signal for path loss calculation to calculate the transmission power of SRS.

[0097] In one possible example, when the beam indication changes from the first SRI to the second SRI, the terminal device can calculate the path loss in the power control parameters of the PUSCH based on the second SSB in the target space-related information in the second SRS resource corresponding to the second SRI.

[0098] Example 6: If the target space-related information indicates the transmission of PUSCH, and the target space-related information includes CSI-RS, CSI-RS can be used as a reference signal for path loss calculation to calculate the transmission power of PUSCH.

[0099] Example 7: If the target space-related information indicates the transmission of SRS, and the target space-related information includes CSI-RS, CSI-RS can be used as a reference signal for path loss calculation to calculate the transmission power of SRS.

[0100] In one possible example, when the beam indication changes from the first MAC CE to the second MAC CE, the terminal device can calculate the path loss in the power control parameters of the SRS based on the second CSI-RS in the target space related information in the second SRS resource corresponding to the second MAC CE.

[0101] Based on this scheme, when the target space-related information includes the target signal, the terminal device can use the target signal as a reference signal for path loss calculation to calculate the path loss in the power control parameters and further calculate the transmission power of the target uplink data.

[0102] Optionally, if the target power control parameters do not configure a road loss calculation reference signal, the reference signal that is quasi-co-located with the control resource set (CORESET) will be used as the road loss calculation reference signal.

[0103] Generally, quasi-co-location (QCL) can be understood as follows: if the channel characteristics of one antenna port symbol can be derived from that of another antenna port, then it is considered that the QCL of these two antenna ports can be used for the channel estimation results obtained from one antenna port.

[0104] Example 8: If a PUSCH is transmitted and the path loss calculation reference signal is not configured in the PUSCH power control parameters indicated by the target space information, the terminal device can use the reference signal that is quasi-co-located with the control resource set as the path loss calculation reference signal to calculate the transmission power of the PUSCH.

[0105] Example 9: If SRS is transmitted and the SRS power control parameters indicated by the target space information do not have a path loss calculation reference signal configured, the terminal device can use the reference signal that is quasi-co-located with the control resource set as the path loss calculation reference signal to calculate the transmission power of SRS.

[0106] It should be noted that when the reference signal co-located with the control resource set is used as the reference signal for path loss calculation, the terminal equipment can determine the transmission power of the target uplink data by combining other parameters configured in the target power control parameters.

[0107] Based on this scheme, if the target power control determined by the terminal device according to the configuration information does not have a path loss calculation reference signal configured, the terminal device can use the reference signal that is quasi-co-located with the control resource set as the path loss calculation reference signal to calculate the transmission power of the target uplink data.

[0108] As shown in Figure 5, this embodiment of the present disclosure provides a terminal device 500, which includes a receiving module 501 and a determining module 502. The receiving module 501 is used to receive configuration information from a network device, the configuration information being used to indicate target space-related information of target uplink data.

[0114] Optionally, any power control parameter may include at least one of the following: the preset received power of the network device, the path loss compensation factor, the path loss calculation reference signal, and the closed-loop power control process; wherein, when the target space-related information includes the target signal, the target signal is the path loss calculation reference signal.

[0115] Optionally, in conjunction with Figure 5, as shown in Figure 6, the terminal device further includes a processing module 503; the processing module 503 is used to use the reference signal that is quasi-co-located with the control resource set as the reference signal for road loss calculation when the target power control parameters are not configured with a road loss calculation reference signal.

[0116] In the terminal device provided in this embodiment, the network device can first send configuration information to the terminal device. This configuration information is used to indicate the target space-related information of the target uplink data. The terminal device can determine the transmission power of the target uplink data according to the target power control parameters indicated by the target space-related information. Compared with traditional uplink transmission, when the space-related information changes, if the target space-related information includes at least one of the following: M power control parameters, the target power control parameters corresponding to the target space-related information, and information indicating the target power control parameters; M is a positive integer, then there is no need to wait for the network device to reconfigure the power control parameters. The terminal device can directly obtain or find the target power control parameters according to the target space-related information indicated by the above configuration information, so that the terminal can use accurate power control parameters to control the power of the target uplink data. This not only avoids the terminal device using inaccurate power to send the target uplink data (i.e., SRS or PUSCH), but also avoids the signaling configuration overhead and latency caused by reconfiguring the power control parameters.

Compared to traditional uplink transmission, when spatial information changes, if the target spatial information includes at least one of the following: M power control parameters, the target power control parameters corresponding to the target spatial information, and information indicating the target power control parameters; where M is a positive integer, then there is no need to wait for the network device to reconfigure the power control parameters.

This allows the terminal to use accurate power control parameters to control the power of the target uplink data.
