[0069] 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.
[0070] In this application's embodiments, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0071] Currently, when the noise floor increases or the wireless communication environment changes, the terminal device can only passively receive the changes, and all uplink transmission power is adjusted with P0 as the target.
[0072] The setting of P0 is determined based on network planning experience and the current wireless communication environment. It needs to ensure that the access network equipment can correctly demodulate the signal strength, while also taking into account the mutual interference between terminal equipment and minimizing the transmission power.
[0073] In related technologies, P0 is a fixed value. In some cases, it may cause power waste for nearby terminals and may interfere with other terminals. In some cases, the uplink transmission power may not be able to continue to increase, affecting the terminal perception of distant terminals.
[0074] However, with constantly changing external interference, there is a possibility of wasted transmission power. For example, for a near-point terminal, when external interference is reduced, the signal-to-interference-plus-noise ratio (SINR) of the reference signal is sufficient to meet the demodulation needs of the near-point terminal. However, the near-point terminal still sends uplink transmissions to the access network equipment at a higher transmission power, which not only wastes power but may also interfere with other terminals. As another example, for a far-point terminal, when the SINR of the reference signal is insufficient to meet the demodulation needs of the far-point terminal, it is necessary to increase the signal-to-noise ratio (SNR) at the receiving end of the access network equipment. However, with P0 unchanged, the transmission power cannot be increased, affecting the terminal's perception.
[0075] To address at least one of the aforementioned problems, this application provides a power determination method, apparatus, access network equipment, and storage medium.
[0076] The power determination method, apparatus, access network equipment, and storage medium of this embodiment are described below with reference to the accompanying drawings. Before specifically explaining the embodiments of this application, for ease of understanding, the technical terms involved in this application are first introduced:
[0077] The initial P0 refers to the pre-configured P0, which can be set by relevant personnel on the access network equipment side before cell activation, based on network planning experience and the current wireless communication environment.
[0078] The target P0 refers to the desired power obtained after adjusting the initial P0.
[0079] The first set RSRP (Reference Signal Receiving Power) threshold can be a preset receiving power threshold or threshold value. This first set RSRP threshold can also be called the near RSRP threshold. The first set RSRP threshold is a relatively high threshold value, used to indicate whether the quality of the reference signal is relatively high, that is, to indicate whether the terminal device (referred to as the target terminal in this application) is a near terminal.
[0080] The second RSRP threshold is also a pre-set received power threshold or threshold value, which can also be called the far-point RSRP threshold (RSRP-threshold-far). The second RSRP threshold is a relatively low threshold value used to indicate whether the quality of the reference signal is relatively low, that is, to indicate whether the terminal device (referred to as the target terminal in this application) is a far-point terminal. The second RSRP threshold is lower than the first RSRP threshold.
[0081] The first set SINR threshold is a preset signal-to-interference-plus-noise ratio (SINR) threshold or value. This first set SINR threshold can also be called the near-terminal (or near-user) SINR high threshold. The first set SINR threshold is a relatively high threshold value used to indicate whether the quality of the reference signal is relatively high.
[0082] The second set SINR threshold is also a preset signal-to-interference-plus-noise ratio (SINR) threshold or value. This second set SINR threshold can also be called the near-terminal (or near-user) SINR low threshold. The second set SINR threshold is a relatively low threshold value used to indicate whether the quality of the reference signal is relatively low; that is, the second set SINR threshold is less than the first set SINR threshold.
[0083] The third SINR threshold is also a pre-set signal-to-interference-plus-noise ratio (SINR) threshold or value. This third SINR threshold can also be called the far-terminal (or far-user) SINR low threshold. The third SINR threshold is a relatively low threshold value used to indicate whether the quality of the reference signal is relatively low. The third SINR threshold is lower than the second SINR threshold; that is, the threshold for the far-terminal is lower than the threshold for the near-terminal.
[0084] The number threshold is set as a pre-defined number threshold value or threshold. This set number threshold can also be called the neighboring cell (NeiborCell) user number threshold (NeiborCell-RRC-num), where RRC refers to Radio Resource Control.
[0085] Set a utilization threshold, which is a pre-defined threshold value or limit for the utilization of Physical Resource Blocks (PRBs). This utilization threshold can also be called the NeiborCell-PRB-ratio.
[0086] Set an interference threshold, which is a pre-defined interference threshold value or threshold. This interference threshold can also be called the NeiborCell-IOT-threshold.

[0089] In this example, a base station is used as an example of an access network device. A base station can include multiple cells providing services to terminal devices. Depending on the specific application, a base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices via one or more sectors on the air interface, or other names. Network devices can be used to exchange received air frames with Internet Protocol (IP) packets, acting as routers between the wireless terminal devices and the rest of the access network, which may include an IP communication network. Network devices 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 Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in Wide-band Code Division Multiple Access (WCDMA), 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 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 base station may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, and the Centralized Unit and Distributed Unit may be geographically separated.
[0090] Terminal devices can be devices that provide voice and / or data connectivity to users, handheld devices 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). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, 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. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application does not limit the terminology.
[0091] like Figure 1 As shown, the power determination method may include the following steps:
[0092] Step 101: Obtain the quality detection information of the serving cell of the target terminal; wherein, the quality detection information is used to indicate the quality of the reference signal within the serving cell.
[0093] The target terminal can be any terminal device within the serving cell.
[0094] In this embodiment of the application, the access network device can be the access network device of the serving cell to which the target terminal is connected.
[0095] In this embodiment of the application, the reference signal within the serving cell may include an uplink reference signal and / or a downlink reference signal.
[0096] The uplink reference signal may include: demodulation reference signal (DMRS) and sounding reference signal (SRS).
[0097] The downlink reference signals may include: Cell-Specific Reference Signal (CS-RS), Multicast Broadcast Single Frequency Network (MBSFN) Reference Signal (MBSFN-RS), UE-Specific Reference Signal (US-RS), Positioning Reference Signal (PRS), and Channel State Information (CSI) Reference Signal (CSI-RS).
[0098] In this embodiment of the application, the access network device can obtain the quality detection information of the serving cell of the target terminal, wherein the quality detection information is used to indicate the quality of the reference signal within the serving cell.
[0099] As an example, the access network device can measure the uplink reference signal within the serving cell to obtain quality detection information, and / or the access network device can acquire quality detection information sent by the target terminal, wherein the quality detection information is obtained by measuring the downlink reference signal within the serving cell.
[0100] Step 102: Adjust the initial P0 according to the quality inspection information to obtain the target P0.
[0101] In this embodiment of the application, the access network device can adjust the initial P0 according to the quality detection information to obtain the target P0.
[0102] Step 103: Send first indication information to the target terminal; wherein the first indication information carries target P0, and target P0 is used by the target terminal to determine the first transmit power of uplink transmission, so as to send uplink transmission to the access network device according to the first transmit power.
[0103] In this embodiment, uplink transmission can be signaling, data, or a combination of signaling and data transmission. Uplink transmission includes, but is not limited to, transmission via the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shard Channel (PUSCH).
[0104] In this embodiment of the application, the access network device can send a first indication information to the target terminal. For example, the first indication information can be RRC reconfiguration information. The first indication information carries a target P0. After receiving the first indication information, the target terminal can determine the uplink transmission power (referred to as the first transmission power in this application) based on the target P0 carried in the first indication information, and then send uplink transmission to the access network device based on the first transmission power.
[0105] The power determination method of this application embodiment obtains the quality detection information of the serving cell of the target terminal; wherein the quality detection information is used to indicate the quality of the reference signal within the serving cell; the initial expected power P0 is adjusted according to the quality detection information to obtain the target P0; and first indication information is sent to the target terminal; wherein the first indication information carries the target P0, and the target P0 is used by the target terminal to determine the first transmit power for uplink transmission, so as to send uplink transmission to the access network equipment according to the first transmit power. Therefore, the expected power can be adjusted according to the actual wireless communication environment information of the target terminal, which can take into account the target terminal's energy consumption and sensing performance, as well as uplink interference, thereby improving the quality and reliability of data transmission in the wireless communication environment.
[0106] To clearly illustrate how the initial P0 is adjusted based on quality detection information in the above embodiments of this application, this application also proposes a power determination method.
[0107] Figure 2 This is a flowchart illustrating another power determination method provided in an embodiment of this application.
[0108] like Figure 2 As shown, the power determination method may include the following steps:
[0109] Step 201: Obtain the quality detection information of the serving cell of the target terminal; wherein, the quality detection information is used to indicate the quality of the reference signal within the serving cell.
[0110] It should be noted that the explanation of the reference signal in the above embodiments also applies to this embodiment, and will not be repeated here.
[0111] The quality inspection information may include the RSRP (referred to as the target RSRP in this application) obtained by measuring the reference signal, and the SINR (referred to as the target SINR in this application) obtained by measuring the reference signal.
[0112] In this embodiment of the application, the access network device can measure the uplink reference signal in the serving cell to obtain the target SINR, and the target terminal can measure the downlink reference signal in the serving cell to obtain the target RSRP and send the target RSRP to the access network device. Correspondingly, the access network device can receive the target RSRP sent by the target terminal.
[0113] Step 202: If the target RSRP is greater than the first set RSRP threshold, determine whether the target SINR is greater than the first set SINR threshold. If yes, proceed to step 203; otherwise, proceed to step 204.
[0114] In this embodiment of the application, if the target RSRP is greater than the first set RSRP threshold, it can be further determined whether the target SINR is greater than the first set SINR threshold. If the target SINR is greater than the first set SINR threshold, step 203 can be executed. If the target SINR is less than or equal to the first set SINR threshold, step 204 can be executed.
[0115] Step 203: Reduce the initial P0 to obtain the target P0.
[0116] In this application embodiment, when the target SINR is greater than the first set SINR threshold, it indicates that the target terminal is a near-point terminal. At this time, in order to reduce the power consumption of the target terminal and reduce the interference generated by the target terminal and caused to other terminals (such as reducing the interference caused to terminal devices accessed in the neighboring cells (referred to as neighboring cells) of the serving cell), the initial P0 can be reduced to obtain the target P0.
[0117] As an example, the initial P0 can be decreased by a first set step size to obtain the target P0. For example, if the first set step size is marked as L1, then the target P0 = initial P0 – L1.
[0118] As another example, the initial P0 can be reduced by a first predetermined ratio to obtain the target P0. For example, if the first predetermined ratio is marked as R1, then the target P0 = initial P0 * R1.
[0119] Step 204: Determine whether the target SINR is less than the second set SINR threshold. If yes, proceed to step 205; otherwise, proceed to steps 206 to 207.
[0120] The second set SINR threshold is smaller than the first set SINR threshold.
[0121] In this embodiment of the application, if the target SINR is less than or equal to the first set SINR threshold, it can be further determined whether the target SINR is less than the second set SINR threshold. If the target SINR is less than the second set SINR threshold, step 205 can be executed. If the target SINR is greater than or equal to the second set SINR threshold, steps 206 to 207 can be executed.
[0122] It should be noted that steps 203 and 204 are two parallel implementation methods, and in actual application, only one needs to be executed.
[0123] Step 205: Increase the initial P0 to obtain the target P0.
[0124] In this embodiment of the application, if the target SINR is less than the second set SINR threshold, it indicates that the target terminal may be a remote terminal. In this case, in order to enhance the uplink demodulation performance and thus improve the terminal perception, the initial P0 can be increased to obtain the target P0.
[0125] As an example, the initial P0 can be increased by a second set step size to obtain the target P0. For example, if the second set step size is marked as L2, then the target P0 = initial P0 + L2.
[0126] As another example, the initial P0 can be increased according to a second predetermined ratio to obtain the target P0. For example, if the second predetermined ratio is marked as R2, then the target P0 = initial P0 * R2.
[0127] Step 206: Keep the initial P0 unchanged.
[0128] In the embodiments of this application, if the target SINR is greater than or equal to the second set SINR threshold, the initial P0 can be kept unchanged.
[0129] Step 207: Send second indication information to the target terminal; wherein the second indication information carries an initial P0, the initial P0 is used by the target terminal to determine the second transmit power of the uplink transmission, so as to send the uplink transmission to the access network device according to the second transmit power.
[0130] It should be noted that the explanation of uplink transmission in the foregoing embodiments also applies to this embodiment, and will not be repeated here.
[0131] In this embodiment of the application, the access network device can send a second indication information to the target terminal. For example, the second indication information can be RRC reconfiguration information. The second indication information carries an initial P0. After receiving the second indication information, the target terminal can determine the uplink transmission transmit power (referred to as the second transmit power in this application) based on the initial P0 carried in the second indication information, and then send uplink transmission to the access network device based on the second transmit power.
[0132] It should be noted that steps 205 and 208 are two parallel implementation methods with steps 206 to 207. In actual application, only one needs to be executed.
[0133] Step 208: Send first indication information to the target terminal; wherein the first indication information carries target P0, and target P0 is used by the target terminal to determine the first transmit power of uplink transmission, so as to send uplink transmission to the access network device according to the first transmit power.
[0134] The explanation of step 208 can be found in the relevant description in any embodiment of this application, and will not be repeated here.
[0135] The power determination method of this application embodiment can effectively adjust the initial P0 based on the RSRP and SINR of the reference signal in the environment where the target terminal is located, so as to balance the power consumption and sensing performance of the target terminal, as well as uplink interference, and improve the quality and reliability of data transmission in the wireless communication environment. For example, for a near-point terminal, if the target RSRP is higher than a first set RSRP threshold, and the target SINR is higher than a first set SINR threshold, P0 can be reduced to reduce the power consumption of the near-point terminal and reduce the interference caused by the near-point terminal to other terminals; if the target SINR is lower than a second set SINR threshold, P0 can be increased to improve the terminal's sensing performance.
[0136] To clearly illustrate how the initial P0 is adjusted based on quality detection information in the above embodiments of this application, this application also proposes a power determination method.
[0137] Figure 3 This is a flowchart illustrating another power determination method provided in an embodiment of this application.
[0138] like Figure 3 As shown, the power determination method may include the following steps:
[0139] Step 301: Obtain the quality detection information of the serving cell of the target terminal; wherein, the quality detection information is used to indicate the quality of the reference signal within the serving cell.
[0140] The quality inspection information may include the RSRP (referred to as the target RSRP in this application) obtained by measuring the reference signal, and the SINR (referred to as the target SINR in this application) obtained by measuring the reference signal.
[0141] The explanation of step 301 can be found in the relevant description of step 201 in the above embodiments, and will not be repeated here.
[0142] Step 302: If the target RSRP is less than or equal to the first set RSRP threshold, determine whether the target RSRP is less than the second set RSRP threshold. If yes, proceed to step 303; otherwise, proceed to steps 307 to 308.
[0143] Wherein, the second set RSRP is less than the first set RSRP threshold.
[0144] In this embodiment of the application, if the target RSRP is less than or equal to the first set RSRP threshold, it can be further determined whether the target RSRP is less than the second set RSRP threshold. If the target RSRP is less than the second set RSRP threshold, step 303 can be executed. If the target RSRP is greater than or equal to the second set RSRP threshold, steps 307 to 308 can be executed.
[0145] It should be noted that steps 303 and 306 are two parallel implementation methods with steps 307 to 308. In actual application, only one needs to be executed.
[0146] Step 303: Determine whether the target SINR is less than the third set SINR threshold. If yes, proceed to step 304; otherwise, proceed to steps 307 to 308.
[0147] Among them, the third SINR setting is less than the second SINR setting.
[0148] In this embodiment of the application, if the target RSRP is less than the second set RSRP threshold, it can be further determined whether the target SINR is less than the third set SINR. If the target SINR is less than the third set SINR threshold, step 304 can be executed. If the target SINR is greater than or equal to the third set SINR threshold, steps 307 to 308 can be executed.
[0149] It should be noted that steps 304 to 306 and steps 307 to 308 are two parallel implementation methods. In actual application, only one needs to be executed.
[0150] Step 304: Obtain the third transmit power used by the target terminal to send uplink transmission to the access network device.
[0151] In this embodiment of the application, if the target SINR is less than the third set SINR threshold, it indicates that the target terminal is a remote terminal. At this time, the actual transmission power (referred to as the third transmission power in this application) used by the target terminal to send uplink transmission to the access network device can be further obtained.
[0152] For example, access network devices can interact with the target terminal to obtain the third transmit power used by the target terminal to actually send uplink transmissions.
[0153] Step 305: Adjust the initial P0 according to the third transmission power to obtain the target P0.
[0154] In this embodiment of the application, the initial P0 can be adjusted according to the third transmission power to obtain the target P0.
[0155] Step 306: Send first indication information to the target terminal; wherein the first indication information carries target P0, and target P0 is used by the target terminal to determine the first transmit power of uplink transmission, so as to send uplink transmission to the access network device according to the first transmit power.
[0156] The explanation of step 306 can be found in the relevant description in any embodiment of this application, and will not be repeated here.
[0157] Step 307: Keep the initial P0 unchanged.
[0158] In this embodiment of the application, if the target RSRP is greater than or equal to the second set RSRP threshold, or if the target SINR is greater than or equal to the third set SINR threshold, it indicates that the transmit power of the target terminal is appropriate. In this case, the initial P0 can be kept unchanged.
[0159] Step 308: Send third indication information to the target terminal; wherein the third indication information carries an initial P0, the initial P0 is used by the target terminal to determine the fourth transmit power of the uplink transmission, so as to send the uplink transmission to the access network device according to the fourth transmit power.
[0160] In this embodiment of the application, the access network device can send a third indication information to the target terminal. For example, the third indication information can be RRC reconfiguration information. The third indication information carries an initial P0. After receiving the third indication information, the target terminal can determine the uplink transmission power (referred to as the fourth transmission power in this application) based on the initial P0 carried in the third indication information, and then send uplink transmission to the access network device based on the fourth transmission power.
[0161] The power determination method of this application embodiment can effectively adjust the initial P0 based on the RSRP and SINR of the reference signal in the environment where the target terminal is located, so as to take into account the power consumption and uplink interference of the target terminal and improve the quality and reliability of uplink transmission in the wireless communication environment. For example, for a remote terminal, if the target RSRP is lower than a second set RSRP threshold and the target SINR is lower than a third set SINR threshold, then the third transmit power actually used by the target terminal is further obtained, and the initial P0 is adjusted according to the third transmit power to take into account the power consumption of the target terminal, reduce the interference caused by the target terminal to other terminals, and improve the terminal's sensing performance.
[0162] To clearly illustrate how the initial P0 is adjusted based on the third transmission power in the above embodiments, this application also proposes a power determination method.
[0163] Figure 4 This is a flowchart illustrating another power determination method provided in an embodiment of this application.
[0164] like Figure 4 The power determination method may include the following steps:
[0165] Step 401: Obtain the quality detection information of the serving cell of the target terminal; wherein, the quality detection information is used to indicate the quality of the reference signal within the serving cell.
[0166] The quality inspection information may include the RSRP (referred to as the target RSRP in this application) obtained by measuring the reference signal, and the SINR (referred to as the target SINR in this application) obtained by measuring the reference signal.
[0167] The explanation of step 401 can be found in the relevant description of step 201 in the above embodiments, and will not be repeated here.
[0168] Step 402: If the target RSRP is less than or equal to the first set RSRP threshold, determine whether the target RSRP is less than the second set RSRP threshold. If yes, proceed to step 403; otherwise, proceed to steps 412 to 413.
[0169] Wherein, the second set RSRP is less than the first set RSRP threshold.
[0170] It should be noted that step 403 and steps 412 to 413 are two parallel implementation methods. In actual application, only one needs to be executed.
[0171] Step 403: Determine whether the target SINR is less than the third set SINR threshold. If yes, proceed to step 404; otherwise, proceed to steps 412 to 413.
[0172] It should be noted that step 404 and steps 412 to 413 are two parallel implementation methods. In actual application, only one needs to be executed.
[0173] Step 404: Obtain the third transmit power used by the target terminal to send uplink transmission to the access network device.
[0174] Step 405: Determine whether the third transmission power is less than the set power threshold. If yes, proceed to step 406; otherwise, proceed to steps 412 to 413.
[0175] It should be noted that step 406 and steps 412 to 413 are two parallel implementation methods. In actual application, only one needs to be executed.
[0176] Step 406: Determine the number of terminal devices accessing neighboring cells of the serving cell and the utilization rate of physical resource blocks (PRBs) of neighboring cells.
[0177] In this embodiment of the application, when the third transmit power is less than a set power threshold, the number of terminal devices accessing the neighboring cells (hereinafter referred to as neighboring cells) of the serving cell and the physical resource block (PRB) utilization rate of the neighboring cells can be further determined.
[0178] As an example, taking the access network equipment as a base station, assume that the base station of the serving cell of the target terminal is base station 1, and the base station of the neighboring cell of the serving cell is base station 2. Then, base station 1 can interact with base station 2 to obtain the number of terminal devices accessing the neighboring cell (hereinafter referred to as the neighboring cell) and the PRB utilization rate of the neighboring cell. For example, base station 1 can send a request message to base station 2. After receiving the request message, base station 2 can respond to the request message by sending a response message to base station 1 carrying the aforementioned number of terminal devices and PRB utilization rate.
[0179] Step 407: Determine whether the number of terminal devices is greater than the set number threshold, and / or whether the PRB utilization rate is greater than the set utilization rate threshold. If yes, proceed to step 408; otherwise, proceed to step 410.
[0180] It should be noted that steps 408 and 410 are two parallel implementation methods, and in actual application, only one needs to be executed.
[0181] Step 408: Increase the initial P0 to obtain the target P0.
[0182] In this embodiment of the application, if the number of terminal devices accessing the adjacent cell is greater than a set threshold, and / or the PRB utilization rate of the adjacent cell is greater than a set utilization rate threshold, P0 can be increased to obtain a target P0. Alternatively, if the interference information of the adjacent cell is less than or equal to a set interference threshold, the initial P0 can be increased to obtain a target P0.
[0183] As an example, the initial P0 can be increased by a second set step size to obtain the target P0. For example, if the second set compensation is marked as L2, then the target P0 = initial P0 + L2.
[0184] As another example, the initial P0 can be increased according to a second predetermined ratio to obtain the target P0. For example, if the second predetermined ratio is marked as R2, then the target P0 = initial P0 * R2.
[0185] Step 409: Send the first instruction information to the target terminal.
[0186] The first indication information carries a target P0, which is used by the target terminal to determine the first transmit power of the uplink transmission, so as to send the uplink transmission to the access network equipment according to the first transmit power.
[0187] The explanation of step 409 can be found in the relevant description in any embodiment of this application, and will not be repeated here.
[0188] Step 410: Obtain interference information from neighboring cells.
[0189] In this embodiment of the application, the access network device can obtain interference information of neighboring cells (hereinafter referred to as neighboring cells) of the serving cell.
[0190] As an example, taking the access network equipment as a base station, assume that the base station of the serving cell of the target terminal is base station 1, and the base station of the neighboring cell of the serving cell is base station 2. Then, base station 1 can interact with base station 2 to obtain interference information from the neighboring cell (referred to as neighboring cell). For example, base station 2 can send XN information to base station 1, where the XN information carries interference information (such as IoT information).
[0191] Step 411: Determine whether the interference information is less than or equal to the set interference threshold. If yes, proceed to step 408; otherwise, proceed to steps 412 to 413.
[0192] It should be noted that step 408 and steps 412 to 413 are two parallel implementation methods. In actual application, only one needs to be executed.
[0193] Step 412: Keep the initial P0 unchanged.
[0194] In this embodiment, if the target RSRP is greater than or equal to a second set RSRP threshold, or if the third transmit power is greater than or equal to a set power threshold, or if the target SINR is greater than or equal to a third set SINR threshold, it indicates that the transmit power of the target terminal is appropriate. In this case, the initial P0 can be kept unchanged. That is, the initial P0 can be kept unchanged when the set conditions are met. The set conditions include at least one of the following: the target RSRP is greater than or equal to the second set RSRP threshold; the target SINR is greater than or equal to the third set SINR threshold; the third transmit power is greater than or equal to the set power threshold; and the interference information is greater than a set interference threshold.
[0195] Step 413: Send the third instruction information to the target terminal.
[0196] In this embodiment of the application, a third indication information can be sent to the target terminal. This third indication information carries an initial P0, which is used by the target terminal to determine a fourth transmit power for uplink transmission, so as to send uplink transmission to the access network device according to the fourth transmit power.
[0197] The power determination method of this application embodiment can effectively adjust the initial P0 based on the RSRP and SINR of the reference signal in the environment where the target terminal is located, thereby improving the terminal's perception performance. For example, for a remote terminal, if the target RSRP is lower than a second set RSRP threshold and the target SINR is lower than a third set SINR threshold, it is further determined whether the third transmit power actually used by the target terminal has reached a set power threshold. If it has not reached the set power threshold, the neighboring cell load (number of terminal devices accessing the neighboring cell, PRB utilization rate, etc.) is further obtained. If the neighboring cell load is relatively small, P0 can be increased. If the neighboring cell load is relatively high, it is determined whether the neighboring cell interference information exceeds a set interference threshold. If it does not exceed the set interference threshold, P0 can be increased to improve the terminal's perception performance.
[0198] To clearly illustrate any embodiment of this application, a power determination method is also proposed.
[0199] Figure 5 This is a flowchart illustrating another power determination method provided in an embodiment of this application.
[0200] like Figure 5 As shown, the power determination method may further include the following steps:
[0201] Step 501: Determine whether an opening operation of the set control is detected. If yes, proceed to steps 502 to 505. If no, proceed to step 506.
[0202] The setting control is used to trigger the adjustment of the initial P0. For example, the setting control can be a P0 adaptive switch, a P0 adjustment switch, a P0 adaptive adjustment switch, etc.
[0203] In this embodiment of the application, the access network device can monitor or listen to the opening operation of the setting control. If the opening operation of the setting control is detected, steps 502 to 505 can be executed. If the opening operation of the setting control is not detected, step 506 can be executed.
[0204] Step 502: Measure the uplink reference signal in the serving cell of the target terminal to obtain the target SINR.
[0205] In this embodiment of the application, when an operation to enable the setting control is detected, the access network device can measure the uplink reference signal in the serving cell of the target terminal to obtain the target SINR.
[0206] Step 503: Receive the target RSRP sent by the target terminal, wherein the target RSRP is obtained by measuring the downlink reference signal in the serving cell.
[0207] In this embodiment of the application, the target terminal can measure the downlink reference signal in the serving cell to obtain the target RSRP, and send the target RSRP to the access network device. Correspondingly, the access network device can receive the target RSRP sent by the target terminal.
[0208] Step 504: Adjust the initial P0 according to the target SINR and target RSRP to obtain the target P0.
[0209] Step 505: Send the first instruction information to the target terminal.
[0210] The first indication information carries a target P0, which is used by the target terminal to determine the first transmit power of the uplink transmission, so as to send the uplink transmission to the access network equipment according to the first transmit power.
[0211] The explanation of steps 504 to 505 can be found in the relevant description in any embodiment of this application, and will not be repeated here.
[0212] Step 506: Send the fourth instruction information to the target terminal.
[0213] The fourth indication information carries an initial P0, which is used by the target terminal to determine the fifth transmit power for uplink transmission, so as to send uplink transmission to the access network equipment according to the fifth transmit power.
[0214] In this embodiment, if no activation operation of the setting control is detected, the initial P0 does not need to be adjusted. The access network device can send a fourth indication information to the target terminal. For example, the fourth indication information can be RRC reconfiguration information. The fourth indication information carries the initial P0. After receiving the fourth indication information, the target terminal can determine the uplink transmission power (referred to as the fifth transmission power in this application) based on the initial P0 carried in the fourth indication information, and then send uplink transmission to the access network device based on the fifth transmission power.
[0215] It should be noted that steps 502 to 505 and step 506 are two parallel implementation methods. In actual application, only one needs to be executed.
[0216] The power determination method of this application embodiment can enable relevant personnel to determine whether to enable the setting control according to actual application needs. When the setting control is enabled, the initial P0 can be adjusted, while when the setting control is not enabled, there is no need to adjust the initial P0, which can meet the actual application needs or actual business needs.
[0217] In any embodiment of this application, taking an access network device as a base station as an example, the target terminal can measure the downlink reference signal in the serving cell to obtain the RSRP, and the base station of the serving cell to which the target terminal is connected can obtain the RSRP transmitted by the target terminal. Furthermore, the base station can measure the uplink reference signal in the serving cell to obtain the SINR. In addition, the base station can also obtain the load information of the serving cell of the target terminal and the load information of the neighboring cells of the serving cell, so as to make a power control decision based on the RSRP, SINR, and the aforementioned load information, and adaptively adjust the P0 power corresponding to the uplink transmission. This reduces the energy consumption of near-point terminals, reduces some of the uplink interference generated by the target terminal to terminal devices connected to neighboring cells, and solves the problem that terminal devices cannot adaptively adjust their transmission power according to changes in the wireless communication environment, thereby improving the sensing performance of some far-point terminals.
[0218] Specifically, assuming the base station of the serving cell of the target terminal is base station 1, and the base station of the neighboring cell of the serving cell is base station 2, base station 1 can determine the location of the target terminal (i.e., whether the target terminal is a far-point terminal or a near-point terminal) based on the RSRP measured by the target terminal for the downlink reference signal and the SINR measured by base station 1 for the uplink reference signal. Based on this location, power control decisions can be made according to a set strategy, and the uplink transmission P0 power can be adaptively adjusted to reduce the energy consumption of the near-point terminal and reduce some of the uplink interference generated by the near-point terminal to its neighboring edge terminals. For the far-point terminal, after comprehensively judging the number of IoT devices in the neighboring cell and the number of terminal devices accessed in the neighboring cell (i.e., the number of users) and the PRB utilization load, the transmit power of the far-point terminal can be further increased to enhance its uplink demodulation performance, thereby improving the terminal's perception performance, while ensuring that it does not cause stronger interference to the neighboring cell. Alternatively, the transmit power of the near-point terminal in the neighboring cell can be reduced to decrease the uplink interference generated by it to the edge terminals of the serving cell of the near-point terminal. This also solves the problem that terminal devices cannot adaptively adjust their transmit power in a timely manner according to changes in the wireless communication environment. After adjusting P0, the target terminal can be notified to make the change via an RRC reconfiguration message.
[0219] The process of adjusting P0 according to the set strategy can be as follows: Figure 6As shown, for a near-point terminal, if RSRP is higher than the first set RSRP threshold (RSRP-threshold-near), and SINR is higher than the first set SINR threshold (SINR-threshold-near-high), then P0 can be reduced. This can reduce the power consumption of the target terminal and reduce the interference caused by the target terminal to other terminals. If SINR is lower than the second set SINR threshold (SINR-threshold-near-low), then P0 can be increased to improve the terminal's sensing performance. For remote terminals, if the RSRP is lower than the second set RSRP threshold (RSRP-threshold-far) and the SINR is lower than the third set SINR threshold (SINR-threshold-far-low), then it is further determined whether the actual transmit power of the target terminal has reached the set power threshold (i.e., the maximum transmit power Pmax). If it has not reached the set power threshold, then the neighboring cell load (the number of terminal devices accessing the neighboring cell (i.e., the number of users), PRB utilization, etc.) is further obtained. If the neighboring cell load is low, P0 can be increased. If the neighboring cell load is high, the neighboring cell IOT information carried in the XN message sent by base station 2 is determined. If the neighboring cell interference in the neighboring cell IOT information does not exceed the set interference threshold (NeiborCell-IOT-threshold), then P0 can be increased to improve the terminal's perception performance. In other cases, P0 remains unchanged.
[0220] according to Figure 6 It can be seen that by adding a setting control (such as a P0 adaptive switch), when this setting control is turned on, it can be triggered. Figure 6 The process shown can be as follows: when the setting control is closed, P0 can remain unchanged; P0 can be adaptively adjusted based on RSRP and SINR, as well as relevant thresholds; P0 can be adaptively adjusted based on load-related information such as the number of terminal devices (i.e., the number of users) and PRB utilization in neighboring cells; and P0 can be adaptively adjusted based on the XN information exchanged between base stations to determine the IOT information of neighboring cells.
[0221] In summary, the adaptive adjustment of P0 can reduce the transmission power of certain near-point terminals while meeting their service requirements, and also reduce the interference generated by these near-point terminals on terminal devices accessing neighboring cells. For some near-point terminals, it can improve terminal perception. For some far-point terminals, considering the load of neighboring cells and the IoT situation, it ensures that there is no strong interference to neighboring cells, while improving the perception performance of far-point terminals in the cell.
