Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a power compensation method and related equipment. Background Technology

[0002] Sounding Reference Signal (SRS) can be used to estimate uplink channel frequency domain information for frequency-selective scheduling; it can also be used to estimate the uplink channel for downlink beamforming. SRS round-robin transmission refers to which physical antenna the terminal uses to transmit SRS information. The more antennas that can participate in transmitting the reference signal, the more accurate the channel estimation, and consequently, the higher the data rate that can be obtained.

[0003] As the number of receiving antennas at the terminal increases, the number of antennas involved in SRS round-robin transmission also increases, and the trigger frequency of antenna round-robin switching also increases significantly. High-frequency antenna switching generates insertion loss. Insertion loss leads to power imbalance among antennas, which greatly affects channel detection results and reduces the accuracy of channel estimation.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure 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 disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0050] 5G networks and other technologies support beamforming, enabling directional transmission to terminals. For a base station to transmit directionally, it must first detect the terminal's location and the quality of the transmission path, allowing for more precise allocation of base station resources to each terminal. Terminals sending SRS (Sounding Reference Signal) information is one method used by base stations to detect terminal location and channel quality.

[0051] SRS, or Sounding Reference Signal, can be used to estimate uplink channel frequency domain information for frequency-selective scheduling and to estimate the uplink channel for downlink beamforming. SRS round-robin transmission refers to which physical antenna the terminal uses to transmit SRS information. In SRS mode, the more antennas that can participate in transmitting the reference signal, the more accurate the channel estimation, and consequently, the higher the data rate. If transmission is only done on a fixed antenna, information from other antennas will be lost, the antennas will not be fully utilized, and it will be difficult to achieve the highest data rate. 5G terminals are generally equipped with multiple transceiver antennas. By fully utilizing the multiple antennas of the 5G terminal to report channel information in turn (i.e., SRS antenna round-robin transmission), the base station can obtain more comprehensive information and perform more accurate data transmission.

[0052] Currently, commercial terminals generally support 4Rx (4-antenna reception), and in 3GPP R18 & 19, 6Rx (6-antenna reception) and 8Rx (8-antenna reception) terminals are also in the standardization and research stage. As the number of receiving antennas in a terminal increases, the number of antennas involved in SRS round-robin transmission also increases, thus significantly increasing the trigger frequency of the SRS antenna round-robin switch. High-frequency SRS antenna switching generates significant insertion loss, leading to a mismatch in transmit power between different antennas, which severely affects the accuracy of the base station's CSI calculation.

[0053] Theoretically, the calculation of SRS transmit power is related to the carrier frequency, carrier, and SRS resources, but not to the port. However, due to the insertion loss caused by antenna switching, the transmit power of each SRS port is reduced to varying degrees, resulting in a power imbalance between SRS ports.

[0054] For 6Rx and 8Rx terminals, each SRS antenna is highly likely to experience the above-mentioned problems. Furthermore, as the number of antennas increases, the number of SRS switching interfaces also increases, leading to a greater difference in insertion loss between the first and subsequent SRS ports (for example, the first SRS port only passes through a single-pole single-throw switch, having a smaller impact on the circuit and lower insertion loss; the sixth SRS port only passes through a single-pole six-throw switch, having a larger impact on the circuit and higher insertion loss). The power imbalance between SRS antennas caused by insertion loss will significantly affect channel detection results and reduce channel estimation accuracy. Simultaneously, because the base station cannot obtain the accurate transmit power of each SRS antenna, it will also affect the reasonable resource scheduling and power allocation for the terminal.

[0055] Figure 1 A flowchart of a power compensation method according to an embodiment of this disclosure is shown, as follows: Figure 1 As shown, the power compensation method provided in this embodiment includes S101.

[0056] In S101, if it is determined that the terminal generates insertion loss of the sounding reference signal, then the insertion loss value of the terminal's sounding reference signal (SRS) port is compensated.

[0057] It is understandable that compensating for insertion loss essentially means increasing the reduction in transmit power of each SRS port caused by insertion loss. In some embodiments, the transmit power of each SRS port can be compensated using the power margin of the aforementioned terminal (UE).

[0058] Figure 2 A flowchart of a power compensation method according to an embodiment of this disclosure is shown, as follows: Figure 2 As shown, the power compensation method provided in this embodiment includes S201-S203.

[0059] In S201, the terminal sends a first capability parameter to the base station. The first capability parameter is used to indicate whether the terminal supports the self-compensation function of Sounding Reference Signal (SRS) insertion loss (IL).

[0060] It should be noted that the first capability parameter may also have other names, such as terminal capability compensation parameter and self-compensation capability parameter, etc., and there is no limitation here. In some embodiments, the English equivalent of the above-mentioned first capability parameter may be SRS-IL-self-compensation-r19, which can be used to indicate whether the UE supports SRS IL self-compensation.

[0061] In S202, if the base station determines that the terminal supports the probe reference signal insertion loss self-compensation function, it sends first information to the terminal, which indicates whether the terminal activates the probe reference signal insertion loss self-compensation function.

[0062] In some embodiments, the terminal (UE) reports the first capability parameter (SRS-IL-self-compensation-r19) to the base station through the terminal capability reporting procedure (RRC UE capability transfer), indicating that the terminal supports the SRS IL self-compensation function. The base station can indicate whether the terminal activates the SRS IL self-compensation function in the RRC IE SRS-config through first information, such as the RRC parameter (SRS-power-compensation). If the RRC parameter (SRS-power-compensation) is configured, the UE performs SRS IL self-compensation (when triggered at an appropriate time).

[0063] The terminal receives the first information sent by the base station. If the first information indicates that the terminal activates the probe reference signal insertion loss self-compensation function, the terminal continues to execute S203.

[0064] In S203, if the insertion loss of the probe reference signal generated by the terminal is determined, the insertion loss value of the probe reference signal port of the terminal is compensated.

[0065] In this embodiment of the present disclosure, the terminal can report to the base station whether it supports the "self-compensation of probe reference signal insertion loss" function, and decide whether to activate this function according to the instructions of the base station. After activating the function, the insertion loss value of the probe reference signal port of the terminal is used for compensation, which can improve the problem of antenna power imbalance between probe reference signal ports caused by insertion loss.

[0066] In some embodiments, compensating for the insertion loss value of the terminal's probe reference signal port may include, for example: Figure 3 The steps shown are as follows: calculate the sum of the insertion loss values ​​of each probe reference signal port of the terminal; determine whether the sum of the insertion loss values ​​of each probe reference signal port of the terminal is greater than the power margin of the terminal to determine whether the terminal has sufficient power margin; if the terminal has sufficient power margin, then compensate for the insertion loss values ​​of all probe reference signal ports of the terminal.

[0067] In some embodiments, compensating for the insertion loss value of the terminal's probe reference signal port may include, for example: Figure 4 The steps shown are as follows: calculate the sum of the insertion loss values ​​of each probe reference signal port of the terminal; determine whether the sum of the insertion loss values ​​of each probe reference signal port of the terminal is greater than the power margin of the terminal to determine whether the terminal has sufficient power margin; if the terminal has sufficient power margin, calculate the power difference between each probe reference signal port of the terminal and determine the maximum value of the power difference; if the maximum value of the power difference is determined to be greater than the first threshold value, then compensate for the insertion loss values ​​of all probe reference signal ports of the terminal.

[0068] In some embodiments, in the above Figure 3 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 5 As shown, starting from the first probe reference signal port of the terminal, the insertion loss value of the probe reference signal port of the terminal is compensated sequentially until the power margin of the terminal is exhausted.

[0069] In some embodiments, in the above Figure 4 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 6As shown, starting from the first probe reference signal port of the terminal, the insertion loss value of the probe reference signal port of the terminal is compensated sequentially until the power margin of the terminal is exhausted.

[0070] In some embodiments, in the above Figure 3 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 7 As shown, the power difference between each probe reference signal port of the terminal is calculated, and the maximum value of the power difference is determined. If the maximum value of the power difference is greater than the second threshold value, then starting from the first probe reference signal port of the terminal, the insertion loss value of the probe reference signal ports of the terminal is compensated sequentially until the power margin of the terminal is exhausted. It should be noted that the second threshold value can be the same as the first threshold value or different from the first threshold value.

[0071] In some embodiments, in the above Figure 4 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 8 As shown, the power difference between each probe reference signal port of the terminal is calculated, and the maximum value of the power difference is determined. If the maximum value of the power difference is greater than the second threshold value, then starting from the first probe reference signal port of the terminal, the insertion loss value of the probe reference signal ports of the terminal is compensated sequentially until the power margin of the terminal is exhausted. It should be noted that the second threshold value can be the same as the first threshold value or different from the first threshold value.

[0072] In some embodiments, in the above Figure 3 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 9 As shown, the transmission power of each detection reference signal port of the terminal is adjusted to make the transmission power of each detection reference signal port of the terminal equal.

[0073] In some embodiments, in the above Figure 4 Based on the implementation examples, if the terminal does not have sufficient power margin, the steps can be as follows: Figure 10 As shown, the transmission power of each detection reference signal port of the terminal is adjusted to make the transmission power of each detection reference signal port of the terminal equal.

[0074] In some embodiments, Figure 9 and Figure 10 In this embodiment, adjusting the transmission power of each detection reference signal port of the terminal to make the transmission power of each detection reference signal port of the terminal equal can be achieved by reducing the transmission power of the port with low insertion loss and increasing the transmission power of the port with high insertion loss, so that the transmission power of each detection reference signal port of the terminal is equal.

[0075] In the above embodiments, compensating for insertion loss essentially increases the reduction in transmit power of each SRS port caused by insertion loss. Therefore, the UE must have sufficient power margin to perform this operation. Secondly, the UE can compensate directly or set a threshold (the first and second thresholds mentioned above). Compensation is only performed when the power difference between ports exceeds the threshold. Finally, when the UE does not have sufficient power margin, certain methods can be used to minimize the power imbalance between ports.

[0076] In the above embodiment, the UE calculates the IL value of each SRS port and determines whether the UE has sufficient power margin (whether the sum of the IL values ​​of each port is greater than the power margin). If it is sufficient, one of the following operations can be performed:

[0077] 1) Compensate for the IL of all SRS ports, or;

[0078] 2) Set a threshold x. When the maximum value of the power difference between each port (calculate the power difference between each pair of ports and take the maximum value) exceeds x, compensate for the IL of all SRS ports.

[0079] If there is insufficient power margin, one of the following operations can be performed:

[0080] 1) Try to compensate the IL of all SRS ports, starting from the first SRS port, and compensate as much as possible until all power margin is used up;

[0081] 2) Set a threshold x. When the maximum value of the power difference between each port (calculate the power difference between each pair of ports and take the maximum value) exceeds x, compensate the IL of all SRS ports. Start from the first SRS port and compensate as much as possible until all power margin is used up.

[0082] 3) Instead of compensating for the IL value of each port, we now ensure that the transmission power of all ports is equal. That is, we reduce the power of the port with the smaller IL to compensate the port with the larger IL, so that the power of all ports is equal.

[0083] Before executing a capability, the UE can report to the base station that it supports that capability. Simultaneously, when the UE's SRS IL compensation function is activated, the base station may also need to know whether the UE has performed compensation, as compensation may not be complete (limited by power margin). The base station needs to know whether the power of the UE's SRS ports is truly consistent after compensation, which will affect subsequent CSI calculations. Therefore, the following scheme is designed.

[0084] In some embodiments, the UE performs SRS IL compensation, but the compensation information is not reported. The UE reports whether it supports IL compensation capability for the SRS port; the base station configures higher-layer parameters and sends them to the UE to activate the function; when the UE generates SRS IL, it uses the scheme in the above embodiments to perform insertion loss compensation.

[0085] In some embodiments, a UE capability parameter (SRS-IL-self-compensation-r19) can be defined to indicate whether the UE supports SRS IL self-compensation.

[0086] If the UE reports the capability parameter (SRS-IL-self-compensation-r19) to the base station through the UE capability transfer procedure (RRC UE capability transfer), it indicates that the UE supports the SRS IL self-compensation function.

[0087] The base station instructs the UE whether to activate the SRS IL self-compensation function via the RRC parameter (SRS-power-compensation, first information) in the RRC IE SRS-config. If the RRC parameter (SRS-power-compensation) is configured, the UE will perform SRS IL self-compensation (when triggered at the appropriate time).

[0088] In some embodiments, the first information instruction also indicates that the terminal reports compensation information.

[0089] In some embodiments, the terminal may also report compensation information to the base station.

[0090] In some embodiments, the compensation information reported by the terminal may include:

[0091] Insertion loss compensation was performed at the probe reference signal port;

[0092] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and whether there was sufficient power margin during compensation;

[0093] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and whether the power of all probe reference signal ports is equal after compensation;

[0094] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and there is sufficient power margin during compensation, and the power of all probe reference signal ports is equal after compensation.

[0095] In this embodiment of the disclosure, the compensation information is reported to the base station, which can improve the accuracy of the base station in calculating CSI (Channel State Information).

[0096] In some embodiments, the UE performs SRS IL compensation and reports the compensation information.

[0097] The UE reports whether it supports IL compensation capability for the SRS port; the base station configures higher-layer parameters and sends them to the UE to activate the SRSIL compensation information reporting function; when the UE generates SRS IL, it uses the scheme in the above embodiment to perform insertion loss compensation, and simultaneously:

[0098] The UE reports the event "IL compensation for SRS port performed";

[0099] Alternatively, the UE reports the event "IL compensation of the SRS port was performed, and there is sufficient power margin during compensation";

[0100] Alternatively, the UE reports the event "IL compensation for the SRS port was performed, and whether the power of all SRS ports is equal after compensation";

[0101] Alternatively, the UE may report the event "IL compensation for the SRS port was performed, and whether there was sufficient power margin during compensation and whether the power of all SRS ports is equal after compensation";

[0102] In some embodiments, a UE capability parameter (SRS-IL-self-compensation-r19) can be defined to indicate whether the UE supports SRS IL self-compensation.

[0103] If the UE reports the capability parameter (SRS-IL-self-compensation-r19) to the base station through the UE capability transfer procedure (RRC UE capability transfer), it indicates that the UE supports the SRS IL self-compensation function.

[0104] The base station instructs the UE whether to activate the SRS IL self-compensation function via the RRC parameter (SRS-power-compensation & reporting, second information) in the RRC IE SRS-config. If the RRC parameter (SRS-power-compensation & reporting) is configured, it indicates that the base station instructs the UE to perform SRS IL self-compensation (at an appropriate time); simultaneously:

[0105] The UE reports whether SRS IL compensation has been performed through the compensation-confirm field (first reported information) of the UEassistanceInformation message in the terminal assistance information reporting process of the RRC layer; when the field is the first value, it indicates that the UE has performed IL compensation of the SRS port.

[0106] The UE reports whether SRS IL compensation has been performed and the power margin during compensation through the compensation & Powerheadroom-confirm field (second reporting information) of the UEassistanceInformation message in the RRC layer terminal assistance information reporting process. When the field is the first value, it indicates that the UE has performed SRS port IL compensation and has sufficient power margin during compensation. When the field is the second value, it indicates that the UE has performed SRS port IL compensation and has insufficient power margin during compensation.

[0107] The UE reports whether SRS IL compensation has been performed and the power status of the SRS ports after compensation through the compensation & PowerperPort-confirm field (third reporting information) of the UEassistanceInformation message in the terminal assistance information reporting process of the RRC layer. When the field is the first value, it indicates that the UE has performed IL compensation for the SRS ports and that the power of all SRS ports is equal after compensation. When the field is the second value, it indicates that the UE has performed IL compensation for the SRS ports and that there are still SRS ports with unequal power after compensation.

[0108] The UE reports whether SRS IL compensation has been performed and the power margin and port power status through the compensation&Powerheadroom&PowerperPort-confirm fields (fourth reporting information) of the UEassistanceInformation message in the RRC layer terminal assistance information reporting process. When this field is the first value, it indicates that the UE has performed SRS port IL compensation and there is sufficient power margin during compensation (when the power margin is sufficient, the power of all ports will be equal after compensation). When this field is the second value, it indicates that the UE has performed SRS port IL compensation and there is insufficient power margin during compensation, and there are still SRS ports with unequal power after compensation. When this field is the third value, it indicates that the UE has performed SRS port IL compensation and there is insufficient power margin during compensation, and the power of all SRS ports is equal after compensation.

[0109] In this embodiment, the terminal has SRS IL compensation capability, which enables the UE to compensate for power imbalance between SRS ports. This compensation is transparent to the base station and has been verified through simulation. This solution can greatly improve the accuracy of channel estimation.

[0110] In embodiments of this disclosure, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0111] In this disclosure, the term "and / or" is merely a description of 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. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0112] Furthermore, although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result.

[0113] In some embodiments, certain steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be broken down into multiple steps for execution.

[0114] Based on the same inventive concept, this disclosure also provides a terminal, such as... Figure 11 As shown, the terminal includes a power compensation module 1101.

[0115] The power compensation module 1101 is used to determine the insertion loss of the probe reference signal generated by the terminal, and then compensate for the insertion loss value of the probe reference signal port of the terminal.

[0116] In some embodiments, the terminal may further include a capability reporting module and an information receiving module.

[0117] The capability reporting module is used to determine the insertion loss of the probe reference signal generated by the terminal. Before compensating the insertion loss value of the probe reference signal port of the terminal, the first capability parameter is sent to the base station. The first capability parameter is used to indicate whether the terminal supports the probe reference signal insertion loss self-compensation function.

[0118] The information receiving module is used to receive the first information sent by the base station. The first information is sent by the base station after determining that the terminal supports the probe reference signal insertion loss self-compensation function. The first information indicates whether the terminal activates the probe reference signal insertion loss self-compensation function.

[0119] In some embodiments, the power compensation module 1101 is used to calculate the sum of the insertion loss values ​​of each probe reference signal port of the terminal; determine whether the sum of the insertion loss values ​​of each probe reference signal port of the terminal is greater than the power margin of the terminal, so as to determine whether the terminal has sufficient power margin; if the terminal has sufficient power margin, then the insertion loss values ​​of all probe reference signal ports of the terminal are compensated.

[0120] In some embodiments, the power compensation module 1101 is used to calculate the sum of the insertion loss values ​​of each probe reference signal port of the terminal; determine whether the sum of the insertion loss values ​​of each probe reference signal port of the terminal is greater than the power margin of the terminal to determine whether the terminal has sufficient power margin; if the terminal has sufficient power margin, calculate the power difference between each probe reference signal port of the terminal and determine the maximum value of the power difference; if the maximum value of the power difference is determined to be greater than a first threshold value, then compensate the insertion loss values ​​of all probe reference signal ports of the terminal.

[0121] In some embodiments, the power compensation module 1101 is further configured to compensate for the insertion loss value of the terminal's probe reference signal port sequentially, starting from the first probe reference signal port of the terminal, if the terminal does not have sufficient power margin, until the terminal's power margin is exhausted.

[0122] In some embodiments, the power compensation module 1101 is further configured to calculate the power difference between each probe reference signal port of the terminal if the terminal does not have sufficient power margin, and determine the maximum value of the power difference; if the maximum value of the power difference is determined to be greater than a second threshold value, then starting from the first probe reference signal port of the terminal, the insertion loss value of the probe reference signal port of the terminal is compensated sequentially until the power margin of the terminal is exhausted.

[0123] It should be noted that the second threshold value can be the same as or different from the first threshold value.

[0126] In some embodiments, the first information instruction also indicates that the terminal reports compensation information.

[0127] In some embodiments, the terminal may further include an information reporting module.

[0128] The information reporting module is used to report compensation information to the base station.

[0129] In some embodiments, the compensation information includes:

[0130] Insertion loss compensation was performed at the probe reference signal port;

[0131] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and whether there was sufficient power margin during compensation;

[0132] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and whether the power of all probe reference signal ports is equal after compensation;

[0133] Alternatively, the insertion loss value compensation of the probe reference signal port was performed, and there is sufficient power margin during compensation, and the power of all probe reference signal ports is equal after compensation.
