Description

Uplink power control processing method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 22, 2024, with application number 202410329888.7 and application name “Uplink power control processing method and device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to an uplink power control processing method and device. Background Art

[0003] During the random access process between the terminal device and the network device, the terminal device may adjust the uplink power according to the power increase amplitude so that the terminal device completes the data interaction during the random access process.

[0004] When a terminal device establishes an RRC (Radio Resource Control) connection with a network device, the terminal device can use the power increase amplitude during random access as the uplink power adjustment value to calculate the uplink power of the terminal device. However, if the network device configures the power configuration field corresponding to the PUCCH in the RRC establishment message, the power increase amplitude during random access will be reset to 0.

[0005] Resetting the power increase range may cause a sudden drop in the uplink power of the terminal device, resulting in abnormal uplink power control of the terminal device.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide an uplink power control processing method and apparatus, which are applied to the field of terminal technology to avoid abnormalities in uplink power control of terminal equipment.

[0008] In a first aspect, an embodiment of the present application provides an uplink power control processing method, which is applied to a terminal device. The method includes:

[0009] In response to a power configuration field sent by a network device, the uplink power of the terminal device is adjusted from a first power value to a second power value. Thereafter, when it is determined based on the first power value and the second power value that a power control abnormality event has occurred, first information is sent to the network device, the first information being used to indicate the occurrence of the power control abnormality event, so that the network device adjusts the power configuration field of a target cell, where the target cell is the cell where the power control abnormality event has occurred.

[0010] In this way, the occurrence of the power control abnormality event is reported to the network device through the first information, so that the network device can adjust the power configuration field of the target cell where the power control abnormality event occurs, thereby specifically solving the problem of uplink power control abnormality, avoiding a sudden drop in the uplink power of the terminal device, and improving the stability and rationality of the uplink power control.

[0011] In a possible implementation, determining whether a power control abnormality event occurs according to the first power value and the second power value includes:

[0012] determining a power drop value, where the power drop value is a difference between the first power value and the second power value; comparing the power drop value with a first preset threshold value to determine whether the power control abnormality event occurs, wherein if the power drop value is greater than or equal to the first preset threshold value, determining that the power control abnormality event occurs; or

[0013] The second power value is compared with a second preset threshold to determine whether the power control abnormality event occurs, wherein if the second power value is less than the second preset threshold, it is determined that the power control abnormality event occurs.

[0014] In this implementation, whether a power control abnormality event occurs is determined based on the power values ​​before and after adjustment, thereby ensuring the correctness of the detected power control abnormality event.

[0015] In a possible implementation manner, the sending the first information to the network device includes:

[0016] Uplink control information is sent to the network device, where the uplink control information includes the first information.

[0017] In this implementation, the terminal device sends the first information through uplink control information (UCI), which enables the terminal device to actively report the first information, thereby enabling instant reporting of the current abnormal power control event, thereby quickly and efficiently resolving the current uplink power abnormality, and allowing the terminal device to restore normal uplink power as soon as possible.

[0018] In a possible implementation, before sending the first information to the network device, the method further includes:

[0019] The uplink power of the terminal device is adjusted from the second power value to a third power value, and the third power value is greater than the second power value.

[0020] In this implementation, the uplink power of the terminal device is increased before sending the first information to ensure that the first information can be effectively sent to the network device, thereby avoiding the situation where the terminal device cannot complete data transmission due to too low uplink power.

[0021] In a possible implementation manner, the sending the first information to the network device includes:

[0022] In response to the first request message sent by the network device, a first response message is sent to the network device, where the first response message includes the first information.

[0023] In this implementation, the terminal device sends the first information to the network device via a first response message (eg, UIR) in response to a request from the network device, thereby effectively reporting the abnormal power control event to the network device.

[0024] In a possible implementation, after determining that an abnormal power control event occurs, the method further includes:

[0025] Record event information corresponding to the power control abnormal event, wherein the event information includes at least one of the following: a power drop value, a timestamp of detecting the power control abnormal event, location information of the power control abnormal event, and cell information of the power control abnormal event.

[0026] In a possible implementation manner, the sending the first information to the network device includes:

[0027] When it is determined that the event information of the recorded power control abnormal event meets the reporting condition, sending the first information to the network device, where the number of the recorded power control abnormal event is one or more;

[0028] Among them, the first information is also used to indicate at least one of the following contents: the power drop value corresponding to each of the power control abnormal events, the timestamp corresponding to each of the power control abnormal events, the location information corresponding to each of the power control abnormal events, the cell information corresponding to each of the power control abnormal events, and the frequency of power control abnormal events occurring within the first unit time length.

[0029] In this implementation method, when the terminal device detects the occurrence of an abnormal power control event, it records the event information of the abnormal power control event, and then generates first information based on the event information of the abnormal power control event. The information content included in the first information is relatively rich, which can provide a rich data basis for the network device to perform information statistics on the abnormal power control event, thereby improving the rationality and correctness of the subsequent network device's adjustment of the power configuration field.

[0030] In a possible implementation, the reporting condition includes at least one of the following: the frequency of the power control abnormal event occurring within the second unit time is higher than a preset frequency, and the number of times the power control abnormal event occurs within a preset time period is greater than a preset number.

[0031] In this implementation, by setting reporting conditions, the first information is sent only when the event information of the power control abnormal event recorded by the terminal device meets the reporting conditions, thereby ensuring the necessity of sending the first information and avoiding unnecessary burden on the network device.

[0032] In a possible implementation, after sending the first information to the network device, the method further includes:

[0033] Receive a power control instruction sent by the network device, where the power control instruction is used to instruct to increase the uplink power of the terminal device.

[0034] In this implementation, the network device sends a power adjustment instruction to the terminal device to increase the uplink power of the terminal device, thereby restoring the uplink power of the terminal device to normal as soon as possible, avoiding long-term impact on data transmission due to low uplink power of the terminal device.

[0035] In a second aspect, an embodiment of the present application provides an uplink power control processing method, which is applied to a network device. The method includes:

[0036] Sending a power configuration field to a terminal device, where the power configuration field is used to instruct adjustment of the uplink power of the terminal device;

[0037] receiving first information sent by the terminal device, where the first information is used to indicate that an abnormal power control event has occurred, and the abnormal power control event is determined based on a first power value before adjustment and a second power value after adjustment of the terminal device;

[0038] The power configuration field of the target cell is adjusted, where the target cell is the cell where the abnormal power control event occurs.

[0039] In a possible implementation, if the power drop value is greater than or equal to a first preset threshold, the first information indicates the power control abnormal event, and the power drop value is the difference between the first power value and the second power value; or,

[0040] If the second power value is less than the second preset threshold, the first information indicates the power control abnormal event.

[0041] In a possible implementation, the receiving the first information sent by the terminal device includes:

[0042] Receive uplink control information sent by the terminal device, where the uplink control information includes the first information.

[0043] In a possible implementation, the receiving the first information sent by the terminal device includes:

[0044] Sending a first request message to the terminal device;

[0045] Receive a first response message sent by the terminal device in response to the first request message, where the first response message includes the first information.

[0074] To facilitate a clear description of the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0075] 1. Terminal equipment

[0076] A terminal device may be a device that includes wireless transceiver functions and can cooperate with network devices to provide communication services to users. Specifically, a terminal device may refer to a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. For example, a terminal device may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, 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 network after 5G, etc. Among them, 5G refers to the fifth generation mobile communication technology (5th Generation Mobile Communication Technology), referred to as 5G.

[0077] 2. Network equipment

[0078] The network device can be a device used to communicate with a terminal device, for example, it can be a base station (Base Transceiver Station, BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication system, it can be a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, it can also be an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network after 5G, or a network device in a future evolved public land mobile network (PLMN) network, etc.

[0079] The network devices involved in the embodiments of the present application may also be referred to as network devices or radio access network (RAN) devices. The RAN device is connected to the terminal device and is used to receive data from the terminal device and send it to the core network device. The RAN device corresponds to different devices in different communication systems. For example, in the 2G system, it corresponds to the base station and the base station controller, in the 3G system, it corresponds to the base station and the radio network controller (Radio Network Controller, RNC), in the 4G system, it corresponds to the evolved base station (Evolutional Node B, eNB), and in the 5G system, it corresponds to the access network device (e.g., gNB, centralized unit CU, distributed unit DU) in the new radio (New Radio, NR).

[0080] 3. Random access process

[0081] The random access involved in the embodiments of the present application may include four-step random access (also referred to as a four-step random access channel, or simply referred to as 4-step RACH) and two-step random access (also referred to as a two-step random access channel, or simply referred to as 2-step RACH). For ease of understanding, the 4-step RACH process is described in detail below with reference to Figure 1. RACH stands for Random Access Channel.

[0082] FIG1 is a schematic diagram of a 4-step RACH process according to an embodiment of the present application. Referring to FIG1 , the process may include:

[0083] S101. The terminal device sends Msg1 to the network device.

[0084] Msg1 may also be referred to as msg1 or MSG1. Msg1 is used to transmit a random access preamble, which may also be referred to as a random access preamble sequence, a preamble, or a preamble sequence.

[0085] In the embodiment of the present application, the preamble and the time-frequency resources occupied by sending the preamble are referred to as physical random access channel (PRACH) resources.

[0086] Optionally, the terminal device may select a PRACH resource and a preamble, and send the selected preamble on the selected PRACH resource. If the random access method is non-contention-based random access, the PRACH resource and preamble may be specified by the base station. The base station may estimate the timing advance (TA) and the uplink grant size required for the terminal device to transmit Msg3 based on the preamble sent by the terminal device.

[0087] For example, the network device may broadcast available PRACH resources through system information.

[0088] S102. The network device sends Msg2 to the terminal device.

[0089] Msg2 may also be referred to as msg2 or MSG2, wherein Msg2 includes the time-frequency resources determined by the network device to be used by the terminal device for sending a payload.

[0090] After the terminal device sends Msg1, it can open a random access response time window (ra-Response Window) and monitor the physical downlink control channel (PDCCH) scrambled by the random access radio network temporary identifier (RA-RNTI) within the random access response time window.

[0091] Among them, RA-RNTI is related to the PRACH time-frequency resources used by the terminal device to send Msg1.

[0092] After a terminal device successfully receives the RA-RNTI-scrambled PDCCH, it can obtain the physical downlink shared channel (PDSCH) scheduled by the PDCCH, which includes a random access response (RAR). The RAR may include the following information:

[0093] The RAR subheader includes a back-off indicator (BI) for indicating the back-off time for retransmitting Msg1.

[0094] RAPID in RAR: preamble index received in network response.

[0095] The RAR payload includes a timing advance group (TAG) for adjusting uplink timing.

[0096] Uplink (UL) grant: an uplink resource indication used to schedule Msg3.

[0097] Temporary cell radio network temporary identifier (C-RNTI): used to scramble the PDCCH of Msg4.

[0098] If the terminal receives the PDCCH scrambled by the RAR-RNTI and the RAR contains the preamble index sent by itself, the terminal considers that the random access response has been successfully received.

[0099] For non-contention-based random access, the random access process ends after the terminal successfully receives Msg2. For contention-based random access, after the terminal successfully receives Msg2, it needs to continue to transmit Msg3 and receive Msg4.

[0100] S103. The terminal device sends Msg3 to the network device.

[0101] Msg3 may also be referred to as msg3 or MSG3. Msg3 is the first scheduled transmission in the random access process, and sends a payload, such as an RRC connection request message, a tracking area update message, and the like.

[0102] Msg3 can inform the network device what event triggered the RACH process. For example, if it is an initial access randomization process, the Msg3 will carry the UE ID and establishment cause; if it is an RRC reestablishment, it will carry the connected UE identifier and establishment cause.

[0103] It should be noted that if different terminal devices select the same preamble in S101 and send the preamble on the same time-frequency resources, the different terminal devices send payloads on the same time-frequency resources, thereby causing resource usage conflict.

[0104] S104. The network device sends Msg4 to the terminal device.

[0105] Msg4 may also be referred to as msg4 or MSG4. Msg4 is used to indicate whether the terminal device has successfully accessed the network device.

[0106] Msg4 can have the following two functions: one is to resolve contention conflicts. The other is for the network device to transmit RRC configuration messages to the terminal device. There are two ways to resolve contention conflicts: one is that if the terminal device carries C-RNTI in Msg3, Msg4 is scheduled with PDCCH scrambled by C-RNTI. The other is that if the terminal device does not carry C-RNTI in Msg3, such as initial access, Msg4 is scheduled with PDCCH scrambled by TC-RNTI. The conflict is resolved by the terminal device receiving the PDSCH of Msg4 and matching the common control channel (CCCH) service data unit (SDU) in the PDSCH.

[0107] 4. Other terms

[0108] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the quantity or execution order, and do not necessarily define differences.

[0109] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0110] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, c can be single or multiple.

[0111] In order to better understand the technical solution of this application, based on the above-mentioned concepts, the relevant technologies involved in this application are further introduced in detail below.

[0112] First, the communication scenario to which the uplink power control processing method in the present application is applicable will be described below with reference to FIG. 2 .

[0113] Figure 2 is a schematic diagram of a communication scenario provided by an embodiment of the present application. Referring to Figure 2 , network device 201 and terminal device 202 are provided. Wireless communication can be performed between network device 201 and terminal device 202. Terminal device 202 can communicate with at least one core network via a radio access network (RAN).

[0114] Among them, the communication system can be a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a Long Term Evolution (LTE) system or a fifth-generation mobile communication (5th-Generation, 5G) system.

[0115] Correspondingly, the network device can be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved NodeB (eNB), an access point (AP) or a relay station in an LTE system, or a base station in a 5G system, etc., without limitation here.

[0116] The 5G mobile communication system described in this application includes a non-standalone (NSA) 5G mobile communication system and / or a standalone (SA) 5G mobile communication system. The technical solution provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system. The communication system can also be a PLMN network, a device-to-device (D2D) network, a machine-to-machine (M2M) network, an IoT network, or other networks.

[0117] It is understandable that if the technical solutions of the embodiments of the present application are applied to other wireless communication networks, the corresponding names can also be replaced by the names of corresponding functions in other wireless communication networks.

[0118] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0119] Based on the communication scenarios described above, terminal devices usually need to establish a connection with network devices to complete the corresponding data interaction.

[0120] When establishing a connection between a terminal device and a network device, if the distance between the terminal device and the network device is short and the path loss experienced by the signal is small, the terminal device can establish communication with the network device with a lower transmit power. Conversely, if the distance between the terminal device and the network device is long and the path loss experienced by the signal is large, the terminal device needs to use a higher transmit power to establish communication with the network device.

[0121] To compensate for transmission losses along different paths and maintain stable received power across network devices, it's necessary to perform transmit power control on the Physical Uplink Control Channel (PUCCH) between the terminal device and the network device. The PUCCH transmit power is also known as uplink power, and controlling the PUCCH transmit power is referred to as uplink power control.

[0122] The following describes an implementation of uplink power control. During the random access process between a terminal device and a network device, the terminal device can continuously adjust the PRACH transmit power according to the Reference Signal Received Power (RSRP) of the current environment until random access is successful.

[0123] For example, when the RSRP in the current environment is relatively poor, the terminal device can continuously increase the transmit power of the PRACH so that the network device can successfully receive the message sent by the terminal device through the PRACH.

[0124] Specifically, during each random access, the terminal device can gradually increase the PRACH transmission power according to the power increase step (for example, it can be recorded as power Ramping Step) configured in the SIB1 (System Information Block 1) sent by the network device. That is, after each random access fails, the PRACH transmission power can be increased by one power Ramping Step and then retried until the terminal device and the network device successfully achieve random access.

[0125] After the terminal device and the network device successfully perform random access, the PRACH transmit power increase amplitude (e.g., PowerRamp-up) can be determined based on the number of terminal device retries and the power Ramping Step. The PRACH transmit power increase amplitude can be understood as the total adjustment amount of the PRACH transmit power of the terminal device and the network device during the random access process. That is, PowerRamp-up = N × powerRampingStep, where N is the number of PRACH retries of the terminal device during the random access process. In this embodiment, the PRACH transmit power increase amplitude can also be simply referred to as the power increase amplitude.

[0126] In one implementation, the PRACH power increase during random access can be used as the transmit power adjustment value to determine the PUCCH transmit power. However, if the network device configures the PUCCH power configuration field (e.g., p0-PUCCH-Value) in the RRC Setup message, the power increase during random access will be reset to 0.

[0127] When the power increase is reset to 0, the PUCCH transmit power may drop suddenly. For example, the PUCCH transmit power may drop from 22.5 to -12. This sudden drop in PUCCH transmit power can cause the transmission of PUCCH information, such as scheduling requests (SRs), to fail. This failure can further lead to uplink data congestion, causing system freezes and even disconnection.

[0128] The problems described above can be collectively understood as abnormalities in the uplink power control of the terminal device. Currently, there is no effective solution to the abnormalities in the uplink power control described above in the relevant technology.

[0129] In response to the shortcomings of current technology in the handling mechanism of uplink power control anomalies, the present application proposes the following technical concept: when the terminal device determines that the power configuration field is configured in the RRC Setup message, the uplink power can be monitored. When the terminal device determines that the uplink power has suddenly dropped, the current abnormal situation can be reported to the network device, so that the network device can adjust the uplink power control of the terminal device to solve the problem of abnormal uplink power control of the terminal device.

[0130] Based on the above introduction, the uplink power control processing method provided by the present application is described below with reference to specific embodiments. First, the description is made with reference to FIG3 , which is a signaling interaction diagram of the uplink power control processing method provided by the embodiment of the present application.

[0131] As shown in FIG3 , the method includes:

[0132] S301. The network device sends a power configuration field to the terminal device.

[0133] In one implementation, the network device may send an RRC Setup message to the terminal device, where the RRC Setup message includes a power configuration field.

[0134] Here is a brief description of how the network device sends the RRC Setup message. Based on the random access process described above, it can be understood that the terminal device can send a random access preamble code through the PRACH channel. After receiving the random access preamble code, the network device can allocate uplink resources to the terminal device. The terminal device can then send an RRC Connection Request message on the Physical Uplink Shared Channel (PUSCH) to establish an RRC connection.

[0135] After receiving the RRC Connection Request message, the network device may send an RRC Setup message to the terminal device and may configure the PUCCH transmit power in the RRC Setup message according to the communication protocol between the network device and the terminal device, so that the terminal device can determine the PUCCH transmit power according to the configuration in the RRC Setup. In this embodiment, the RRC Setup message includes a power configuration field, where the power configuration field may be the p0-PUCCH-Value described above.

[0136] In this embodiment, the power configuration field is used to instruct the terminal device to adjust its uplink power. On the one hand, based on the above introduction, it can be determined that when the power configuration field is included in the RRC Setup message, the power increase amplitude during the random access process will be reset to 0, and then the uplink power of the corresponding terminal device will be adjusted. On the other hand, the power configuration field p0-PUCCH-Value itself can also indicate the power adjustment value of the PUCCH transmission power (that is, the uplink power in this embodiment). For example, the larger the value of p0-PUCCH-Value, the larger the power adjustment value of the corresponding uplink power, that is, the greater the degree of uplink power increase.

[0137] S302. The terminal device adjusts the uplink power of the terminal device from a first power value to a second power value in response to the power configuration field.

[0138] After receiving the power configuration field from the network device, the terminal device can adjust the uplink power of the terminal device according to the power configuration field.

[0139] The terminal device can adjust the uplink power of the terminal device from a first power value to a second power value in response to the power configuration field. In this embodiment, the first power value and the second power value are not fixed power values, wherein the first power value is the uplink power of the terminal device before power adjustment according to the power configuration field, which depends on the transmit power condition when the terminal device receives the power configuration field. And the second power value is the uplink power of the terminal device after power adjustment according to the power configuration field, which depends on the indication of the power configuration field.

[0140] Therefore, the current embodiment introduces that the terminal device adjusts the uplink power from the first power value to the second power value, which does not mean that the uplink power is adjusted from a specific value to another specific value. The uplink power before and after the adjustment depends on the actual implementation. This embodiment does not limit the specific values ​​of the first power value and the second power value.

[0141] S303: The terminal device determines, based on the first power value and the second power value, that an abnormal power control event occurs.

[0142] After adjusting the uplink power in response to the power configuration field, the terminal device can determine whether a power control abnormality event occurs based on the adjustment of the uplink power.

[0143] In one implementation, the terminal device may determine a difference between the first power value and the second power value to obtain a power reduction value, and then compare the power reduction value with a first preset threshold to determine whether a power control abnormality event has occurred.

[0144] For example, when the power drop value is greater than or equal to a first preset threshold, it can be determined that the uplink power of the terminal device has suddenly dropped, and therefore it can be determined that an abnormal power control event has occurred. Conversely, when the power drop value is less than the first preset threshold, it can be determined that although the uplink power of the terminal device has been adjusted, no sudden drop has occurred, and therefore it can be temporarily determined that no abnormal power control event has occurred.

[0145] The first preset threshold is a threshold used to measure whether a sudden drop in uplink power occurs. For example, the first preset threshold may be 10 dB. This embodiment does not impose any particular limitation on the specific setting of the first preset threshold, which may be set according to actual needs.

[0146] In another implementation, the terminal device may also compare the adjusted second power value with a second preset threshold value to determine whether an abnormal power control event occurs.

[0147] For example, when the second power value is less than the second preset threshold, it can be determined that the adjusted uplink power of the terminal device is too low, and therefore it can be determined that an abnormal power control event has occurred. Conversely, when the second power value is greater than or equal to the second preset threshold, it can be determined that although the uplink power of the terminal device has been adjusted, the power is not too low, and therefore it can be temporarily determined that no abnormal power control event has occurred.

[0148] The second preset threshold is used to measure whether the adjusted uplink power is too low. For example, the first preset threshold may be -10 db. This embodiment does not impose any particular limitation on the specific setting of the second preset threshold, which may be set according to actual needs.

[0149] In actual implementation, the specific method used to measure whether a power control abnormality event has occurred can be selected based on actual needs. For example, the two implementation methods described above can be combined, and a power control abnormality event is determined to have occurred only when both conditions described above are met. The power control abnormality event in this embodiment can be understood as an event in which an abnormality occurs in the uplink power control of the terminal device. On this basis, the method for determining a power control abnormality event can be arbitrarily expanded based on actual needs.

[0150] S304: The terminal device sends first information to the network device.

[0151] When the terminal device determines that an abnormal power control event has occurred, the terminal device may send first information to the network device, where the first information is used to indicate that an abnormal power control event has occurred in the terminal device, so that the network device can collect the abnormal power control event.

[0152] In one implementation, the first information may only indicate that a power control abnormality event has occurred in the terminal device; or, the first information may also indicate that a power control abnormality event has occurred in the terminal device due to the power configuration field. In the latter implementation, in addition to informing the network device that a power control abnormality event has occurred, the network device can also be made clear that the cause of the current power control abnormality event is the unreasonable configuration of the power configuration field, thereby improving the efficiency of exception handling.

[0153] S305: The network device adjusts the power configuration field of the target cell in response to the first information.

[0154] Afterwards, the network device can determine that an abnormal power control event has occurred based on the first information. Based on the collected abnormal power control events, the network device can adjust the power configuration field of the target cell where the abnormal power control event occurred to avoid the above-mentioned abnormality in the uplink power control of the terminal device.

[0155] The power configuration field of the network device may be adjusted by not including the power configuration field in the RRC Setup message to avoid a sudden drop in the uplink power of the terminal device or a second power value after adjustment being too low. Alternatively, the power configuration field may be included in the RRC Setup message, but the value of the power configuration field is large, which can also avoid a sudden drop in the uplink power of the terminal device or a second power value after adjustment being too low, thereby avoiding abnormalities in the uplink power control of the terminal device.

[0156] The uplink power control processing method and apparatus provided in the embodiments of the present application, after a terminal device adjusts the uplink power according to the power configuration field sent by a network device, determines whether a power control abnormality event has occurred based on the uplink power before and after the adjustment. If it is determined that a power control abnormality event has occurred, the terminal device can report the occurrence of the power control abnormality event to the network device through a first message, so that the network device can adjust the power configuration field of the target cell where the power control abnormality event has occurred, thereby specifically resolving the problem of uplink power control abnormality, avoiding a sudden drop in the uplink power of the terminal device, and improving the stability and rationality of uplink power control.

[0157] Based on the above introduction, the implementation methods of the terminal device sending the first information to the network device may include, for example, the following two methods: the first is that the terminal device can actively send the first information to the network device; the second is that the terminal device responds to the requirements of the network device and passively sends the first information to the network device.

[0158] The following describes two implementation methods of the terminal device sending the first information to the network device and related solution implementations.

[0159] The first type: the terminal device actively sends the first information to the network device.

[0160] This can be understood in conjunction with Figure 4, which is a first interactive diagram of the first information provided in an embodiment of the present application.

[0161] 4 , in this implementation, the terminal device may, for example, send uplink control information (UCI) to the network device after detecting an abnormal power control event. The uplink control information may include the first information described above.

[0162] For example, a new information element can be defined in the UCI to carry the first information, thereby reporting abnormal power control events. Alternatively, existing information elements in the UCI can be reused to carry the first information, thereby reporting abnormal power control events. This embodiment does not specifically limit the information element in the UCI that carries the first information; it can be configured based on actual needs, as long as the first information can be sent to the network device via the UCI.

[0163] In an extensible implementation, the terminal device may also send the first information through other uplink messages, as long as the uplink message can be actively sent by the terminal device. This embodiment does not limit the specific implementation of the uplink message for sending the first information.

[0164] It is also understood that in this implementation method where the terminal device proactively reports, the terminal device independently determines the time to send the first information. In one implementation method, upon determining that an abnormal power control event has occurred, the terminal device may immediately send the first information to the network device, thereby promptly reporting the abnormal power control event to the network device, allowing the network device to quickly resolve the abnormal power control event.

[0165] In addition, in order to ensure that the first information can be sent to the network device as soon as possible, the first information can be set to only indicate power control abnormal events (or power control abnormal events caused by the power configuration field) to increase the speed of generating the first information and ensure the timeliness of the first information sent to the network device for indicating power control abnormal events.

[0166] Alternatively, the first information may include some simple additional information, such as the cell information where the terminal device is located, the location information of the terminal device, etc., so that the network device can collect more relevant information about the abnormal power control event. In actual implementation, the specific content included in the first information can be set according to actual needs, as long as the first information can be reported to the network device in a timely manner when the abnormal power control event occurs.

[0167] However, when it is determined that an abnormal power control event has occurred, the uplink power of the terminal device is at the second power value described above, wherein the adjusted second power value is relatively small. Therefore, to ensure that the terminal device can effectively send the first information to the network device, the terminal device may further adjust the uplink power of the terminal device from the second power value to a third power value before sending the first information, wherein the third power value is greater than the second power value.

[0168] In one implementation, the third power value can be equal to the first power value, for example, that is, before sending the first information, the uplink power of the terminal device can be restored to the power value before adjustment to ensure that the first information can be effectively sent to the network device.

[0169] Alternatively, the third power value may be any other value, as long as the third power value is greater than the second power value. In actual implementation, for example, a fixed third power value may be pre-set to adjust the uplink power of the terminal device to the third power value as a fixed value. Alternatively, a power increase value may be pre-set and then added to the second power value to obtain the third power value. This embodiment does not limit the specific value of the third power value.

[0170] If the first information can be successfully reported to the network device, the network device can send a power control instruction to the terminal device after receiving the first information, where the power control instruction is used to instruct to increase the uplink power of the terminal device to resolve the power control anomaly currently occurring in the terminal device, so that the terminal device can recover to the uplink power that can normally send and receive data as soon as possible, avoiding affecting data transmission.

[0171] The power control instruction may, for example, instruct that the uplink power of the terminal device be increased by a first value, or may also instruct that the uplink power of the terminal device be increased to a second value, wherein the first value and the second value may be pre-agreed, or may also be dynamically indicated by the power control instruction. Alternatively, the power control instruction may also indicate a new power configuration field, so that the terminal device determines its uplink power according to the new power configuration field, thereby achieving an increase in the uplink power of the terminal device. This embodiment does not impose any particular limitation on the specific indication method of the power control instruction, as long as the power control instruction can be used to instruct the uplink power of the terminal device to increase.

[0172] Here's another way to send the first message:

[0173] The second type: the terminal device passively sends the first information to the network device in response to a request from the network device.

[0174] This can be understood in conjunction with Figure 5, which is a second interactive diagram of the first information provided in an embodiment of the present application.

[0175] 5 , in this implementation, the network device may send a first request message to the terminal device. The first request message may be, for example, a UE Information Request message. The first request message is used to instruct the terminal device to report corresponding data.

[0176] Afterwards, the terminal device may send a first response message to the network device in response to the first request message, where the first response message may be, for example, a UE Information Response (UE information response message, referred to as UIR), and the first response message is used to report corresponding data to the network device.

[0177] Then in one implementation, the first response message may be configured to include the first information, thereby enabling the terminal device to send the first information to the network device.

[0178] In the implementation where the terminal device passively sends the first information, the implementation of the first request message and the first response message is not limited to the two types of information described above. As long as the first request message is sent by the network device and is used to instruct the terminal device to report the corresponding data, this embodiment does not limit the implementation of the first request message and the first response message as long as the first response message is sent by the terminal device in response to the first request message and is used to report the corresponding data of the terminal device.

[0179] It is also understandable that in an implementation where the terminal device passively sends the first information, the timing of sending the first information is not controlled by the terminal device, but depends on when the network device sends the first request message to the terminal device. It is possible that the network device sends the first request message to the terminal device some time after the power control anomaly occurs, and only then can the terminal device respond to the network device's request and send the first information to the network device.

[0180] Therefore, in the current implementation method, the purpose of the terminal device sending the first information to the network device is usually not to immediately resolve the power control abnormality event that occurs in the terminal device, but to uniformly report the power control abnormality events within a period of time to the network device, so that the network device can clearly understand the details of the power control abnormality event that occurs in the terminal device.

[0181] Referring to the above introduction, it can be understood that this implementation method of the terminal device passively sending the first information does not actually require the terminal device to quickly generate the first information. Therefore, the first information can be set to include richer feedback content, thereby providing the network device with richer information related to power control abnormal events.

[0182] In one implementation, after a power control abnormality event occurs, the terminal device may record event information corresponding to the power control abnormality event. Multiple power control abnormality events may occur on the terminal device, so, for example, one piece of event information may be recorded for each power control abnormality event. The event information may include at least one of the following: a power reduction value corresponding to the power control abnormality event, a timestamp of when the power control abnormality event was detected, location information of the power control abnormality event, and cell information of the cell where the power control abnormality event occurred.

[0183] The location information may be, for example, the location information of the terminal device where the abnormal power control event occurred. The location information may be, for example, in the form of latitude and longitude, or in the form of coordinates, which is not limited in this embodiment. The cell information may be, for example, information related to the cell where the terminal device where the abnormal power control event occurred is located. For example, the information may include the cell identifier, location, and cell parameters. Any information related to the cell where the abnormal power control event occurred may be used as the cell information in this embodiment.

[0184] Furthermore, in the actual implementation process, the specific content included in the event information can be further expanded according to actual needs, which is not limited in this embodiment.

[0185] After the terminal device records the event information of the power control abnormality event, if it receives a first request message sent by the network device, the terminal device can generate first information based on the recorded event information of the power control abnormality event, and then send a first response message to the network device to send the first information to the network device.

[0186] In one implementation, the first information can indicate at least one power control abnormality event recorded by the terminal device, wherein the first information can not only be used to indicate that a power control abnormality event has occurred in the terminal device, but can also indicate at least one of the following contents: the power drop value corresponding to each power control abnormality event, the timestamp corresponding to each power control abnormality event, the location information corresponding to each power control abnormality event, the cell information corresponding to each power control abnormality event, and the frequency of power control abnormality events within the first unit time length.

[0187] The first unit time length may be, for example, one hour, or one day, and the present embodiment does not impose any particular limitation on the specific length of the first unit time length. Taking one hour as an example, the frequency of abnormal power control events occurring within the second unit time length may be, for example, five abnormal power control events occurring within one hour.

[0188] When determining the frequency of abnormal power control events within the first unit time, for example, the average frequency of abnormal power control events within the first unit time may be calculated based on the event information of the abnormal power control events recorded by the terminal device, and the average frequency of abnormal power control events within the first unit time may be reported to the network device. Alternatively, the maximum frequency of abnormal power control events within the first unit time may be calculated based on multiple event information recorded by the terminal device, and the average frequency of abnormal power control events within the first unit time may be reported to the network device.

[0189] Furthermore, when sending the first information via the first response message, for example, a new information element may be added to the first response message, thereby carrying the first information via the new information element. Alternatively, an existing information element in the first response message may be reused to carry the first information, which is not limited in this embodiment.

[0190] Regarding the implementation method of carrying the first information by adding a new information element, illustratively, it is assumed that the first response message is UE Information Response, and the UE Information Response includes an rlf-Cause-r16 field, where rlf is a radio link failure (Radio Link Failure).

[0191] The rlf-Cause-r16 field includes multiple enumeration values. For example, a new value may be added to the multiple enumeration values ​​of rlf-Cause-r16. Assume that the newly added value is called p0-PUCCH-ValueMisconfiguration, where the new value p0-PUCCH-ValueMisconfiguration can be understood as a newly added information element for carrying the first information.

[0192] For example, in the case of a power anomaly event, the newly added information element p0-PUCCH-ValueMisconfiguration may include at least one of the following:

[0193] UnsuitableP0-PUCCH-Value: This parameter is used to record power abnormality events caused by incorrectly configured p0-PUCCH-Value of network devices.

[0194] PowerDropLevel: This parameter is used to record the specific value of power drop, which is the power drop value introduced above.

[0195] EventTimestamp: This parameter is used to record the timestamp of the power abnormality event.

[0196] EventFrequency: This parameter is used to record the frequency of power anomaly events within the first unit time (such as per hour).

[0197] The newly added information element may also include location information and cell information corresponding to the power control abnormal event, which are not listed here.

[0198] With reference to the above introduction, it can be determined that by adding a new information element in the first response message to carry the first information, it is possible to report the relevant information of the power abnormality event to the network device.

[0199] Furthermore, based on the above description, in one implementation, when recording event information of a power anomaly event, a terminal device may, for example, activate the newly added information element described above, thereby recording the event information of the power anomaly event using the relevant parameters in the newly added information element. In this implementation, it can be understood that the first information sent by the terminal device and the event information recorded by the terminal device are actually the same information. By activating the newly added information element and recording the event information, the terminal device actually generates the first information.

[0200] When the first information needs to be sent later, the terminal device can directly determine the newly added information element that has recorded the relevant event information as the information element carrying the first information, and then send the first information to the network device.

[0201] Furthermore, after receiving the first request message sent by the network device, the terminal device may directly send a first response message to the network device in response to the first request message, and send the first information to the network device via the first response message. Alternatively, before sending the first response message to the network device, the terminal device may first determine whether the event information of at least one currently recorded power control abnormal event meets the reporting condition, and only send the first information to the network device when the reporting condition is determined to be met.

[0202] By setting reporting conditions, the accuracy and necessity of power anomaly events reported to network devices can be improved, thereby avoiding reporting relevant information of power anomaly events to network devices when unnecessary, causing the network devices to undertake unnecessary analysis and processing work.

[0203] The reporting conditions may include, for example, at least one of the following: the frequency of the abnormal power control event occurring within the second unit time is higher than a preset frequency, and the number of times the abnormal power control event occurs within a preset time period is greater than a preset number.

[0204] The second unit time is similar to the first unit time, and can be, for example, one hour or one day, which is not limited in this embodiment. Taking one hour as an example, the frequency of abnormal power control events occurring within the second unit time can be, for example, three abnormal power control events occurring within one hour. Similar to the above description, the preset frequency here can be an average frequency or a maximum frequency, which is not limited in this embodiment.

[0205] Furthermore, the preset time period may be, for example, a period corresponding to a certain length of time before the current time, such as 12 hours before the current time, or 24 hours before the current time. Taking 12 hours as an example, the number of power control abnormality events occurring within the preset time period may be, for example, eight power control abnormality events occurring within the past 12 hours. In actual implementation, the specific selection and setting of the preset time period may be based on actual needs, and this embodiment does not impose any limitation thereto.

[0206] Furthermore, the preset frequency and the preset number of times described above are threshold parameters for determining whether to report the first information, and can be set arbitrarily according to actual needs. For example, the preset frequency can be set to 5 times, and the preset number of times can be set to 10 times. This embodiment does not impose any particular restrictions on this.

[0207] Regarding the implementation method of the terminal device passively sending the first information, although the purpose of the terminal device sending the first information is usually not to resolve the power abnormality event that is currently occurring, the network device can still try to adjust the uplink frequency of the terminal device to resolve the power abnormality event of the terminal device as much as possible.

[0208] Therefore, after receiving the first information, the network device can send a power control instruction to the terminal device, where the power control instruction is used to instruct to increase the uplink power of the terminal device. The power control instruction is the same as that introduced in the above embodiment and will not be repeated here.

[0209] To sum up, the implementation method in which the terminal device responds to the requirements of the network device and passively sends the first information to the network device can feed back the relevant information of the power abnormality events recorded within a period of time to the network device, so as to provide the network device with relatively rich feedback content of the power abnormality events, facilitate the network device to collect information on the power abnormality events, and thus make targeted adjustments, thereby improving the rationality and correctness of subsequent uplink power control.

[0210] Two implementations of the terminal device sending the first information are introduced above, but it can be understood that the two implementations introduced above can actually coexist.

[0211] That is, the terminal device can proactively send the first information to the network device immediately upon the occurrence of a power control abnormality event, thereby immediately and quickly sending the first information indicating the power control abnormality event to the network device, so that the network device can adjust the uplink power of the terminal device in real time, thereby quickly resolving the abnormal uplink power control state of the terminal device. It can be understood that this operation can, from a micro perspective, achieve the fastest possible resolution of a power control abnormality event for a single terminal device.

[0212] At the same time, upon receiving the first request message from the network device, the terminal device can still passively send the first information to the network device via the first response message, thereby uniformly reporting the event information of multiple power abnormality events recorded by the terminal device over a period of time to the network device, so that the network device can collect the event information of the power control abnormality event and then specifically adjust the power configuration field of the target cell involved in the power control abnormality event. This operation can improve the rationality and correctness of the network device's subsequent uplink power control for multiple terminal devices from a macro perspective.

[0213] In addition, based on the above introduction, it is also necessary to distinguish the action of the network device adjusting the power configuration field of the target cell from the action of the network device sending a power control instruction to the terminal device.

[0214] Among them, the network device sends a power control instruction to the terminal device in order to adjust the current uplink power of the terminal device in an attempt to correct the power control abnormality event caused by the incorrect configuration of the power configuration field, so that the terminal device can restore normal uplink power as soon as possible.

[0215] However, network equipment typically adjusts the target cell's power configuration field not to address a specific power anomaly event for a specific terminal device, but rather to optimize the network device's uplink power control processing to improve the rationality and accuracy of the network device's uplink power control for the terminal device. For example, the network device typically adjusts the target cell's power configuration field after the terminal device reports a power control anomaly event.

[0216] For example, assuming that the network device receives the first information sent by terminal device 1 at time a and the first information sent by terminal device 2 at time b, the network device will then collect statistics on the power control abnormality events of the target cells corresponding to the two terminal devices (and may also include other terminal devices) based on the first information sent by the two terminal devices. Based on the statistical results, the network device will then adjust the power configuration field of the target cell.

[0217] Then, for example, the network device will send the adjusted power configuration field to the terminal device 3 (for example, belonging to a target cell) at time c to avoid a sudden drop in the uplink power of the terminal device 3. The network device will also perform uplink power control on the remaining terminal devices in the target cell according to the adjusted power configuration field, thereby improving the overall rationality of the network device's uplink power control of the terminal devices.

[0218] In one implementation, the network device can, for example, identify the pattern and range of abnormal power control events based on the first information sent by multiple terminal devices, and then make targeted adjustments to the power configuration field based on the identified pattern and range. For example, assuming the identified pattern and range of abnormal power control events are: abnormal power control events occur frequently in cell 1 within a time period d, the network device can increase the power configuration field of cell 1 within the time period d, thereby avoiding the occurrence of abnormal power control events.

[0219] In the actual implementation process, how the network device specifically classifies the mode and scope of power abnormality events, and how to set corresponding adjustment strategies based on the identification results, all depend on the actual implementation of the network device. This embodiment does not impose any restrictions on this, as long as the purpose of the network device is to improve the rationality and correctness of uplink power control and avoid power control abnormality events caused by the power configuration field.

[0220] Furthermore, after adjusting the power configuration field of the target cell, the network device may monitor the first information reported by the terminal device over a long period of time to evaluate the effectiveness of the adjustment of the power configuration field. Furthermore, the network device may periodically update the power control algorithm of the terminal device, such as by updating the aforementioned determination conditions for power anomaly events and the reporting conditions for the first information, thereby optimizing anomaly detection and reporting logic.

[0221] In summary, the uplink power control processing method provided by this application introduces a new statistical event of RLF failure to provide a more accurate and efficient method to count and process uplink power control anomalies. This method not only helps to promptly identify and resolve uplink power control problems, but also provides important support for the stable operation and optimization of 5G networks. In addition, the above process also details how to apply the method provided by this application in an actual network environment, thereby providing network operators with a detailed data processing basis.

[0222] The uplink power control processing method according to the embodiment of the present application has been described above. The following describes an apparatus for executing the uplink power control processing method provided by the embodiment of the present application. Those skilled in the art will appreciate that the method and apparatus may be combined and referenced with each other, and that the relevant apparatus provided by the embodiment of the present application may execute the steps in the uplink power control processing method.

[0223] FIG6 is a structural diagram of an uplink power control processing device according to an embodiment of the present application. As shown in FIG6 , the device 60 includes: a processing module 601 and a transceiver module 602;

[0224] The processing module 601 is used to adjust the uplink power of the terminal device from a first power value to a second power value in response to the power configuration field sent by the network device; the processing module 601 is also used to determine whether a power control abnormality event occurs based on the first power value and the second power value; the transceiver module 602 is used to send first information to the network device when it is determined that a power control abnormality event occurs, and the first information is used to indicate the occurrence of the power control abnormality event, so that the network device adjusts the power configuration field of the target cell, and the target cell is the cell where the power control abnormality event occurs.

[0225] In one possible design, the processing module 601 is specifically configured to:

[0226] determining a power drop value, where the power drop value is a difference between the first power value and the second power value; comparing the power drop value with a first preset threshold value to determine whether the power control abnormality event occurs, wherein if the power drop value is greater than or equal to the first preset threshold value, determining that the power control abnormality event occurs; or

[0227] The second power value is compared with a second preset threshold to determine whether the power control abnormality event occurs, wherein if the second power value is less than the second preset threshold, it is determined that the power control abnormality event occurs.

[0228] In one possible design, the transceiver module 602 is specifically configured to:

[0229] Uplink control information is sent to the network device, where the uplink control information includes the first information.

[0230] In one possible design, the processing module 601 is further configured to:

[0231] Before sending the first information to the network device, the uplink power of the terminal device is adjusted from the second power value to a third power value, and the third power value is greater than the second power value.

[0232] In one possible design, the transceiver module 602 is specifically configured to:

[0233] In response to the first request message sent by the network device, a first response message is sent to the network device, where the first response message includes the first information.

[0234] In one possible design, the processing module 601 is further configured to:
