[0002] In traditional deployment schemes for Time Division Duplex (TDD) systems, neighboring cells maintain consistent TDD configurations to avoid severe cross-interference. To better adapt to service transmission, base stations can dynamically adjust their TDD configurations.

[0075] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system.

[0077] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0078] The uplink power control method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0079] Please see Figure 2 , Figure 2 This is a flowchart illustrating an uplink power control method provided in an embodiment of this disclosure. It should be noted that the uplink power control method of this embodiment can be executed by a terminal device. It should also be noted that the uplink power control method of this embodiment can be applied to dynamic TDD (Time Division Duplex) scenarios. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0080] In step 201, the first configuration information sent by the network device is received.

[0081] It should be noted that in dynamic TDD scenarios, there is cross-interference between uplink and downlink transmissions between different cells. This cross-interference can be divided into interference between network devices (such as base stations) and interference between terminal devices. Under different interference conditions, network devices can configure different first configuration information for terminal devices. This first configuration information can be used to instruct the terminal device to determine at least one set of uplink power control parameters.

[0082] Regarding interference between network devices (such as base stations), the network device in this disclosure is the interfered network device, and the terminal device in this disclosure is the interfered terminal device serving the network device. In one implementation, the first configuration information is configured by the interfered network device based on the interference level on at least one resource set. The interference level of the at least one resource set is obtained by the interfered network device performing interference measurements on the downlink signal of the interfering network device at a predetermined time-frequency location.

[0083] In other words, for interference between network devices (such as base stations), the interfered network device performs interference measurement on the downlink signal of the interfering network device at a predetermined time-frequency location, determines the interference level of at least one resource set, and configures first configuration information for the interfered terminal device based on the interference level on the at least one resource set.

[0084] Regarding interference between terminal devices, the network device in this disclosure is an interfering network device, and the terminal device in this disclosure is an interfering terminal device serving the network device. In one implementation, the first configuration information is configured by the interfering network device based on the interference level on at least one resource set. The interference level of the at least one resource set is obtained by the interfering terminal device performing interference measurement on the uplink signal of the interfering terminal device at a predetermined time-frequency location. Furthermore, the interference level of the at least one resource set is sent by the interfering terminal device to the interfering network device through the network device serving the interfering terminal device, or the interference level of the at least one resource set is sent by the interfering terminal device to the interfering network device. The interfering terminal device is the terminal device interfered with by the interfering terminal device.

[0085] Optionally, taking a network device as a base station as an example, for interference between terminal devices, the interfered terminal device reports the interference level of at least one resource set to the serving base station, and the serving base station forwards the interference level of the at least one resource set to the interfering base station. Alternatively, for interference between terminal devices, the interfered terminal device directly reports the interference level of at least one resource set to the interfering base station. The interfering base station configures first configuration information for the interfering terminal device based on the interference level on the at least one resource set.

[0086] In step 202, at least one set of uplink power control parameters is determined.

[0087] In the embodiments of this disclosure, each set of uplink power control parameters may include, but is not limited to, parameters such as target received power and / or power adjustment step size.

[0088] Optionally, after receiving the first configuration information sent by the network device, the terminal device determines at least one set of uplink power control parameters. As an example, the terminal device can determine at least one set of uplink power control parameters based on the first configuration information.

[0089] In one implementation, the at least one set of uplink power control parameters can be configured independently. That is, at least one set of uplink power control parameters can be configured independently based on different configuration parameters. For example, if there are two sets of uplink power control parameters, such as parameter set 1 and parameter set 2, then parameter set 1 can be configured using configuration parameter 1, and parameter set 2 can be configured using configuration parameter 2.

[0090] In another implementation, the first configuration information may include an uplink power control parameter reference set and an offset value. The terminal device can determine at least one uplink power control parameter set based on the uplink power control parameter reference set and offset value in the first configuration information.

[0091] Optionally, the first configuration information may include an uplink power control parameter reference set and at least one offset value. The terminal device can determine the uplink power control parameters in at least one uplink power control parameter set based on the uplink power control parameters in the uplink power control parameter reference set and the at least one offset value. The number of offset values ​​may be the same as the number of parameters in the uplink power control parameter reference set, or the number of offset values ​​may be one less than the number of parameters in the uplink power control parameter reference set. For example, if the uplink power control parameter reference set is not one of the parameter sets in the at least one uplink power control parameter set, the number of offset values ​​may be the same as the number of parameters in the uplink power control parameter reference set; if the uplink power control parameter reference set is one of the parameter sets in the at least one uplink power control parameter set, the number of offset values ​​may be one less than the number of parameters in the uplink power control parameter reference set.

[0092] For example, taking the number of at least three uplink power control parameter sets as an example, assuming that the first configuration information includes an uplink power control parameter reference set (such as reference parameter set 1) and two offset values ​​(such as offset value 1 and offset value 2), the terminal device can determine the first uplink power control parameter set based on reference parameter set 1, determine the second uplink power control parameter set based on reference parameter set 1 and offset value 1, and determine the third uplink power control parameter set based on reference parameter set 1 and offset value 2.

[0093] For example, taking the case where there are at least two uplink power control parameter sets, assuming that the first configuration information includes an uplink power control parameter reference set (such as reference parameter set 1) and two offset values ​​(such as offset value 1 and offset value 2), the terminal device can determine the first uplink power control parameter set based on reference parameter set 1 and offset value 1, and determine the second uplink power control parameter set based on reference parameter set 1 and offset value 2.

[0094] In step 203, the uplink power control parameter set corresponding to the target transmission resource set is selected from at least one set of uplink power control parameters.

[0095] In embodiments of this disclosure, the target transmission resource set may include transmission resources in the time domain or frequency domain.

[0096] Optionally, the terminal device can select the uplink power control parameter set corresponding to the target transmission resource set from at least one set of uplink power control parameters. In other words, the terminal device can determine from the first configuration information which sets of uplink power control parameters the network device has configured for it, and select the uplink power control parameter set corresponding to the target transmission resource set from these sets.

[0097] In step 204, uplink power adjustment is performed on the target transmission resource set.

[0098] In one implementation, the terminal device can perform uplink power adjustment on a target transmission resource set using an uplink power control parameter set corresponding to that target transmission resource set. In embodiments of this disclosure, the number of target transmission resource sets can be one or more.

[0099] By implementing the embodiments of this disclosure, taking into account the different interference conditions on different transmission resources, uplink power adjustment can be performed using different uplink power parameters under different interference conditions, effectively avoiding interference to neighboring cells and effectively reducing the power consumption of terminal devices.

[0100] It should be noted that in dynamic TDD scenarios, there is cross-interference between uplink and downlink transmissions between different cells. This cross-interference can be divided into interference between network devices (such as base stations) and interference between terminal devices. For interference between network devices (such as base stations), the uplink power of the interfered terminal device needs to be adjusted to effectively avoid interference to neighboring cells and effectively reduce the power consumption of the terminal device. For interference between terminal devices, the uplink power of the interfering terminal device needs to be adjusted to effectively avoid interference to neighboring cells and effectively reduce the power consumption of the terminal device. The following will describe this application in detail from the two aspects of interference between network devices (such as base stations) and interference between terminal devices.

[0101] Please see Figure 3 , Figure 3 This is a flowchart illustrating another uplink power control method provided in this disclosure. It should be noted that this method can be executed by a terminal device. It should also be noted that the uplink power control method of this disclosure can be applied to dynamic TDD scenarios. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0102] In step 301, the first configuration information sent by the network device is received.

[0103] In the embodiments of this disclosure, step 201 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0104] In step 302, at least one set of uplink power control parameters is determined.

[0105] In the embodiments of this disclosure, step 302 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0106] In step 303, the pattern information of the target transmission resource set sent by the network device is received.

[0107] Optionally, the terminal device can receive pattern information of the target transmission resource set sent by the network device, and the terminal device can understand which transmission resources the network device has specifically configured for the terminal device based on the pattern information.

[0108] In step 304, the interference level of the target transmission resource set sent by the receiving network device is determined.

[0109] Optionally, network devices may have different levels of interference on different sets of transmission resources. The network device can send the level of interference on the target set of transmission resources to the terminal device. The terminal device can receive the level of interference for the target set of transmission resources sent by the network device.

[0110] In step 305, based on the pattern information and the level of interference, the uplink power control parameter set corresponding to the target transmission resource set is selected from at least one set of uplink power control parameters.

[0111] In one implementation, the terminal device can receive pattern information of a target transmission resource set from the network device and determine the configuration parameters for performing uplink transmission on the target transmission resource set. The terminal device can then select a set of uplink power control parameters to be used on the target transmission resource set based on the level of interference on that set.

[0112] In step 306, uplink power adjustment is performed on the target transmission resource set.

[0113] In the embodiments of this disclosure, step 306 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0114] By implementing the embodiments of this disclosure, the terminal device receives the pattern information of the target transmission resource set of the network device and the interference level of the target transmission resource set, selects the set of uplink power control parameters to be used on the target transmission resource set, and performs uplink power adjustment on the target transmission resource set using the corresponding set of uplink power control parameters. This allows different uplink power parameters to be used to perform uplink power adjustment under different interference conditions, effectively avoiding interference to neighboring cells and effectively reducing the power consumption of the terminal device.

[0115] Please see Figure 4 , Figure 4This is a flowchart illustrating another uplink power control method provided in this disclosure. It should be noted that this method can be executed by a terminal device. It should also be noted that the uplink power control method of this disclosure can be applied to dynamic TDD scenarios. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0116] In step 401, the first configuration information sent by the network device is received.

[0117] In the embodiments of this disclosure, step 401 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0118] In step 402, at least one set of uplink power control parameters is determined.

[0119] In the embodiments of this disclosure, step 402 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0120] In step 403, the pattern information of the target transmission resource set sent by the network device is received.

[0121] Optionally, the terminal device can receive pattern information of the target transmission resource set sent by the network device, and the terminal device can understand which transmission resources the network device has specifically configured for the terminal device based on the pattern information.

[0122] In step 404, the second configuration information sent by the network device is received.

[0123] In the embodiments of this disclosure, the second configuration information is used to indicate the set of uplink power control parameters corresponding to the target transmission resource set. That is, the second configuration information can be used to indicate the mapping relationship between the target transmission resource set and the uplink power control parameter set.

[0124] In one implementation, there is a correspondence between the transmission resource set and the uplink power control parameter set; that is, each transmission resource set has a corresponding uplink power control parameter set. The terminal device receives pattern information of the target transmission resource set sent by the network device, and receives second configuration information of the corresponding uplink power control parameter set for each transmission resource set, so that the terminal device can determine the mapping relationship between the transmission resource set and the uplink power control parameter set.

[0125] In step 405, based on the pattern information and the second configuration information, the uplink power control parameter set corresponding to the target transmission resource set is selected from at least one set of uplink power control parameters.

[0126] Optionally, the terminal device can learn from the pattern information which target transmission resource sets the network device has specifically configured for the terminal device, and learn from the second configuration information the mapping relationship between the target transmission resource sets and the uplink power control parameter sets. In this way, the terminal device can select the uplink power control parameter set corresponding to the target transmission resource set from at least one uplink power control parameter set based on the pattern information and the second configuration information.

[0127] For example, suppose that after receiving the first configuration information sent by the network device, the terminal device determines that the network device has configured uplink power control parameter set 1, uplink power control parameter set 2, and uplink power control parameter set 3 for the terminal device. After receiving the pattern information sent by the network device, the terminal device understands that the network device has specifically configured target transmission resource set a and target transmission resource set b for the terminal device. After receiving the second configuration information sent by the network device, the terminal device understands the mapping relationship between the target transmission resource set and the uplink power control parameter set. For example, the second configuration information includes an indication field, which is used to indicate the mapping relationship between the target transmission resource set and the uplink power control parameter set. For example, if the indication field is 00, it indicates the mapping relationship between target transmission resource set a and uplink power control parameter set 1, that is, target transmission resource set a corresponds to uplink power control parameter set 1. Or, if the indication field is 01, it indicates the mapping relationship between target transmission resource set b and uplink power control parameter set 2, that is, target transmission resource set b corresponds to uplink power control parameter set 2. In this way, the terminal device can select the uplink power control parameter set corresponding to the target transmission resource set from uplink power control parameter set 1, uplink power control parameter set 3, and uplink power control parameter set 3, based on the pattern information and the second configuration information.

[0128] In step 406, uplink power adjustment is performed on the target transmission resource set.

[0129] In the embodiments of this disclosure, step 406 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0130] By implementing the embodiments of this disclosure, the terminal device selects the set of uplink power control parameters to be used on the target transmission resource set according to the pattern information and second configuration information of the target transmission resource set, and performs uplink power adjustment on the target transmission resource set using the corresponding set of uplink power control parameters. This allows different uplink power parameters to be used to perform uplink power adjustment under different interference conditions, effectively avoiding interference to neighboring cells and effectively reducing the power consumption of the terminal device.

[0131] Please see Figure 5 , Figure 5 This is a flowchart illustrating another uplink power control method provided in this disclosure. It should be noted that this method can be executed by a terminal device. It should also be noted that the uplink power control method of this disclosure can be applied to dynamic TDD scenarios. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0132] In step 501, the first configuration information sent by the network device is received.

[0133] In the embodiments of this disclosure, step 501 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0134] In step 502, at least one set of uplink power control parameters is determined.

[0135] In the embodiments of this disclosure, step 502 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0136] In step 503, the instruction information sent by the network device is received.

[0137] In embodiments of this disclosure, the indication information is used to indicate the set of uplink power control parameters corresponding to the target transmission resource set.

[0138] In one implementation, an indication of the uplink power control parameter set can be carried in the downlink control information (DCI). This indication can be carried explicitly or implicitly.

[0139] In step 504, based on the indication information, an uplink power control parameter set corresponding to the target transmission resource set is selected from at least one set of uplink power control parameters. Optionally, the target transmission resource set may also be indicated in the indication information.

[0140] In one implementation, in an explicit manner, the target information field in the DCI can indicate the set of uplink power control parameters on the target transmission resource set. Optionally, the correspondence between the target information field and the uplink power control parameter set needs to be configured in advance, for example, as shown in the table below:

[0141] Table 1 shows the correspondence between the target information domain and the uplink power control parameter set in DCI.

[0142] Instruction information Parameter set indication 00 Parameter set 1 01 Parameter set 2 10 Parameter set 3 11 Parameter set 4

[0143] Taking Table 1 above as an example, if the indication information in the target information field of DCI is 01, it corresponds to parameter set 2 in the uplink power control parameter set. If the indication information in the target information field of DCI is 11, it corresponds to parameter set 4 in the uplink power control parameter set.

[0144] It is understood that each element in Table 1 above exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in Table 1. Therefore, those skilled in the art will understand that the value of each element in Table 1 is an independent embodiment. It should be noted that the embodiments of this disclosure include multiple tables, and each of these tables is similar to Table 1, combining multiple independent embodiments into the same table, and each element in these tables should also be considered an independent embodiment.

[0145] In another implementation, in an implicit manner, the set of uplink power control parameters for the current scheduling instruction can be implicitly carried through Radio Network Temporary Identifier (RNTI) or scrambling sequences. For example, using RNTI, a correspondence between RNTI and uplink power control parameter sets can be defined, and the terminal device determines the uplink power control parameter set corresponding to the target transmission resource set based on the scrambled RNTI value on the DCI. Alternatively, orthogonal scrambling sequences can be defined, with different scrambling sequences corresponding to different uplink power control parameter sets. These scrambling sequences are applied to the target indication information, and the terminal determines the uplink power control parameter set corresponding to the target transmission resource set based on the detected scrambling sequences.

[0146] In step 505, uplink power adjustment is performed on the target transmission resource set.

[0147] In the embodiments of this disclosure, step 505 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0148] By implementing the embodiments of this disclosure, the terminal device receives signaling instructions from the network device, selects the set of uplink power control parameters to be used on the target transmission resource set, and performs uplink power adjustment on the target transmission resource set using the corresponding set of uplink power control parameters. This allows different uplink power parameters to be used to perform uplink power adjustment under different interference conditions, effectively avoiding interference to neighboring cells and effectively reducing the power consumption of the terminal device.

[0149] It is understood that the above embodiments describe the implementation of the uplink power control method of this disclosure from the perspective of the terminal device. This disclosure also proposes an uplink power control method, the implementation of which will be described below from the perspective of the network device.

It should be noted that the uplink power control method in this embodiment can be executed by a network device. Figure 6 As shown, the method may include, but is not limited to, the following steps.

[0150] In step 601, first configuration information is configured based on the degree of interference of at least one resource set.

[0151] It should be noted that in dynamic TDD scenarios, there is cross-interference between uplink and downlink transmissions between different cells. This cross-interference can be divided into interference between network devices (such as base stations) and interference between terminal devices. Under different interference conditions, network devices can configure different first configuration information for terminal devices. This first configuration information can be used to instruct the terminal device to determine at least one set of uplink power control parameters.

This allows the terminal device to perform uplink power adjustment using different uplink power parameters under different interference conditions, effectively avoiding interference to neighboring cells and effectively reducing the power consumption of the terminal device.
