Method and apparatus for communication

[0001] This application claims priority to the Chinese Patent Application No. 202411354792.2, filed on September 26, 2024, and entitled "Method and apparatus for communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and more particularly, to a method and apparatus for communication. BACKGROUND

[0003] The China Radio Administration issued the "26GHz Frequency Band 5G Millimeter Wave Innovation Guidelines for Public Comment" requiring that in the 24.75-27.5GHz frequency band range, the total radiated power (TRP) threshold value above the horizontal plane is 25dBm / 200MHz, which can be understood as the TRP requirement of the entire upper hemisphere being less than or equal to 25dBm / 200MHz. This regulation constraint is referred to as the "upper hemisphere regulation".

[0004] Currently, methods of lowering the downtilt angle of the radio frequency module of the base station or reducing the equivalent isotropically radiated power (EIRP) of the radio frequency module of the base station are used to meet the TRP requirement of the entire upper hemisphere, but this will cause the coverage distance to decrease, affecting the coverage ability of the base station and the user experience, thereby leading to a decrease in communication performance. SUMMARY

[0008] Based on the above technical solution, in the case that the predicted average total transmit power is greater than the preset threshold, at least one of the transmit power of the data signal, the transmit power of the control signal, or the transmit power of the access signal is reduced in the time window according to the priority information. Compared with the scheme of reducing the downtilt angle of the radio frequency module of the base station and reducing the EIRP of the radio frequency module of the base station, the embodiments of the present application can reduce the impact on the coverage range and the user experience while ensuring that the TRP meets the regulatory requirements, thereby improving the communication performance.

[0061] In order to facilitate the understanding of the embodiments of the present application, the technical solutions related to the embodiments of the present application are briefly introduced as follows.

[0062] I. Regulatory policy

[0063] China District No. 26Ghz frequency band 5G millimeter wave innovation guide draft requires that in the range of 24.75~27.5GHz frequency band, the TRP threshold value above the horizontal plane is 25dBm / 200MHz, which can be understood as requiring the entire upper hemisphere TRP to be less than or equal to 25dBm / 200MHz. This regulation constraint is referred to as the "upper hemisphere regulation". Fig. 4 is a schematic diagram of the TRP power threshold value above the horizontal plane being 25dBm / 200MHz.

[0064] II. Regulatory agency acceptance method

[0065] The total radiation emission power is monitored by a spectrum analyzer in a darkroom. The time slot of the spectrum analyzer is aligned with the downlink slot of the base station. The measured power of all measurement points on the upper hemisphere of all antennas of the base station is integrated and averaged. Fig. 5 is a schematic diagram of the time window monitored by the spectrum analyzer; the time window includes 4 time slots, wherein "D" represents the downlink time slot, "S" represents the flexible time slot, and "U" represents the uplink time slot. The downlink time slot is used to transmit downlink signals, the uplink time slot is used to transmit uplink signals, and the flexible time slot can be used to transmit downlink signals or uplink signals.

[0066] III. Method for reducing total radiation emission power

[0067] 1. Lowering the downtilt angle of the radio frequency module of the base station

[0068] In order to meet the TRP requirement of the entire upper hemisphere, the downtilt angle of the radio frequency module of the base station is lowered, but this will cause the coverage distance to decrease, thereby affecting the coverage ability of the base station and the user experience. Fig. 6 is a schematic diagram showing that lowering the downtilt angle of the radio frequency module causes the coverage distance to decrease; the downtilt angle of the radio frequency module is lowered from 8.5 degrees to 12.1 degrees, and the coverage distance is reduced from 200m to 140m.

[0069] 2. Reducing the EIRP of the radio frequency module of the base station

[0070] In order to meet the TRP requirement of the entire upper hemisphere, the EIRP of the radio frequency module of the base station is reduced, but the coverage distance is reduced, thereby affecting the coverage capability of the base station and the user experience. FIG. 7 is a schematic diagram of the reduction of the coverage distance caused by the reduction of the EIRP of the radio frequency module; taking the reduction of 1 dB of the EIRP of the radio frequency module and the coverage distance of 200 m before the reduction of the power as an example, according to the formula: reduction of dB = 20*log(coverage distance before the reduction of the power) - 20*log(coverage distance after the reduction of the power), the coverage distance after the reduction of the power is calculated as 179 m by reverse calculation, and the coverage is damaged by 21 m.

[0071] As can be seen from the above, the reduction of the down-tilt angle and the direct reduction of the power of the cell will both cause the reduction of the coverage range of the base station, result in the coverage damage of the access user, and affect the user experience rate. Therefore, how to reduce the influence on the coverage range and the user experience while meeting the regulation requirement of the TRP needs to be considered.

[0072] Therefore, an embodiment of the present application provides a communication method, which can reduce the influence on the coverage range and the user experience while meeting the regulation requirement of the TRP, thereby improving the communication performance.

[0073] FIG. 8 is a schematic flow interaction diagram of a communication method 800 provided by an embodiment of the present application. The execution subject of the communication method 800 provided by the embodiment of the present application can be a network device or a module (such as a circuit, a chip, a chip system or a processor) in the network device, and can also be a logic node, a logic module or software capable of realizing all or part of the function of the network device. The chip can be a modem chip, also known as a baseband chip; or can be a system on chip (SoC) chip containing a modem core; or can be a system in package (SIP) chip. The network device in the embodiment of the present application can be a base station or an access network device.

[0074] S810, predicting an average total transmission power, the average total transmission power including a sum of average transmission powers above a horizontal plane respectively corresponding to a plurality of signals in a time window: an access signal for accessing a network, a control signal carried on a PDCCH, and a data signal carried on a PDSCH. The average total transmission power in the embodiment of the present application can be understood as the TRP; and the average transmission power can be understood as the average scheduling power.

[0075] Optionally, the average total transmitting power is predicted according to the total transmitting power corresponding to each of the plurality of beams used for transmitting the plurality of signals and the power component corresponding to each of the plurality of beams, wherein the power component corresponding to a beam comprises a ratio of the transmitting power above the horizontal plane corresponding to the beam to the total transmitting power corresponding to the beam.

[0076] For example, the average transmitting power above the horizontal plane of the access signal within the time window is predicted according to the total transmitting power corresponding to each of the at least one first beam used for transmitting the access signal and the power component corresponding to each of the at least one first beam. The average transmitting power above the horizontal plane of the control signal within the time window is predicted according to the total transmitting power corresponding to each of the at least one second beam used for transmitting the control signal and the power component corresponding to each of the at least one second beam. The average transmitting power above the horizontal plane of the data signal within the time window is predicted according to the total transmitting power corresponding to each of the at least one third beam used for transmitting the data signal and the power component corresponding to each of the at least one third beam. The average total transmitting power is determined according to the average transmitting power above the horizontal plane corresponding to each of the access signal, the control signal and the data signal within the time window.

[0077] The transmitting power δ1 above the horizontal plane of the access signal can be represented by the following formula (1):

[0078] wherein P i represents the transmitting power of the beam i used for transmitting the access signal within the cell, C i represents the power component of the beam i, and I represents the number of the at least one first beam used for transmitting the access signal.

[0079] The transmitting power δ2 above the horizontal plane of the control signal can be represented by the following formula (2):

[0080] wherein P j represents the transmitting power of the beam j used for transmitting the control signal within the cell, C j represents the power component of the beam j within the cell, and J represents the number of the at least one second beam used for transmitting the control signal.

[0081] The transmitting power δ3 above the horizontal plane of the data signal can be represented by the following formula (3):

[0082] wherein P k represents the transmitting power of the beam k used for transmitting the data signal within the cell, C krepresents a power component of the beam k in the cell, and K represents a number of at least one third beam used for transmitting the data signal.

[0083] S820, according to the priority information, reducing the transmission power of at least one of the data signal, the control signal, or the access signal in the time window, so that the average total transmission power after the transmission power is reduced is less than or equal to the preset threshold. In other words, in the case that the predicted average total transmission power is greater than the preset threshold, according to the priority information, the transmission power of at least one of the data signal, the control signal, or the access signal is reduced in the time window, so that the average total transmission power after the transmission power is reduced is less than or equal to the preset threshold. The preset threshold in the present application can be understood as a regulation threshold or a TRP threshold value 25dBm / 200MHz; the average total transmission power less than or equal to the preset threshold can be understood as that the TRP meets the regulation requirements.

[0084] In the technical scheme provided in the embodiments of the present application, in the case that the predicted average total transmission power is greater than the preset threshold, at least one of the transmission power of the data signal, the control signal, or the access signal is reduced in the time window according to the priority information. Compared with the scheme of reducing the downtilt angle of the radio frequency module of the base station and reducing the EIRP of the radio frequency module of the base station, the embodiments of the present application can reduce the impact on the coverage range and the user experience while realizing that the TRP meets the regulation requirements, thereby improving the communication performance.

[0085] Optionally, in the case that the predicted average total transmission power is greater than the preset threshold, the transmission power of at least one of the data signal or the control signal is reduced in the time window according to the priority information, and the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the control signal. In this optional scheme, the transmission power of the access signal can not be changed, so that the signal quality of the access signal can be ensured not to decrease while realizing that the average total transmission power is less than or equal to the preset threshold (the TRP meets the regulation requirements), thereby reducing the impact on the coverage range.

[0086] Optionally, in the case that the predicted average total transmission power is greater than the preset threshold, and the average transmission power above the horizontal plane of the access signal is also greater than the preset threshold, the transmission power of the access signal is reduced, so that the average transmission power above the horizontal plane of the access signal after the transmission power is reduced is less than or equal to the preset threshold; and according to the priority information, the transmission power of at least one of the data signal or the control signal is reduced in the time window, and the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the control signal, so that the average total transmission power after the transmission power is reduced is less than or equal to the preset threshold.

[0087] It should be noted that according to the priority information, the transmission power of at least one of the data signal or the control signal is reduced in the time window, and the priority information indicates that the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the control signal. Specifically, it can be understood that according to the priority information, it is determined to preferentially reduce the transmission power of the data signal in the time window. If the average total transmission power after reducing the transmission power of the data signal is still greater than the preset threshold, it is determined to reduce the transmission power of the control signal. If the average total transmission power after reducing the transmission power of the data signal is less than or equal to the preset threshold, it is determined not to reduce the transmission power of the control signal.

[0088] Optionally, in the case that the predicted average total transmission power is greater than the preset threshold, according to the priority information, the transmission power of at least one of the data signal or the access signal is reduced in the time window, and the priority information indicates that the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the access signal. In this optional scheme, the transmission power of the control signal can not be changed, which can ensure that the signal quality of the control signal does not decrease while realizing that the average total transmission power is less than or equal to the preset threshold (TRP meets the regulatory requirements), and to a certain extent, the influence on user experience can be reduced.

[0089] Exemplarily, in the case that the predicted average total transmission power is greater than the preset threshold, and the average total transmission power above the horizontal plane of the control signal is also greater than the preset threshold, the transmission power of the control signal is reduced so that the average total transmission power above the horizontal plane of the control signal after reduction is less than or equal to the preset threshold; and according to the priority information, the transmission power of at least one of the data signal or the access signal is reduced in the time window, and the priority information indicates that the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the access signal, so that the average total transmission power after reducing the transmission power is less than or equal to the preset threshold.

[0090] It should be noted that according to the priority information, the transmission power of at least one of the data signal or the access signal is reduced in the time window, and the priority information indicates that the priority of reducing the transmission power of the data signal is higher than the priority of reducing the transmission power of the access signal. Specifically, it can be understood that according to the priority information, it is determined to preferentially reduce the transmission power of the data signal in the time window. If the average total transmission power after reducing the transmission power of the data signal is still greater than the preset threshold, it is determined to reduce the transmission power of the control signal. If the average total transmission power after reducing the transmission power of the data signal is less than or equal to the preset threshold, it is determined not to reduce the transmission power of the control signal.

[0091] Optionally, in the case that the predicted average total transmit power is greater than the preset threshold, at least one of the transmit power of the data signal, the transmit power of the control signal, or the transmit power of the access signal is reduced in the time window according to the priority information, the priority information indicating that the priority of reducing the transmit power of the data signal is higher than the priority of reducing the transmit power of the control signal, and the priority of reducing the transmit power of the control signal is higher than the priority of reducing the transmit power of the access signal. In this optional scheme, the priority of reducing the transmit power of the access signal is the lowest, and thus the possibility of reducing the transmit power of the access signal is the smallest. The signal quality of the access signal can be ensured from being degraded while the average total transmit power is less than or equal to the preset threshold (TRP meets the regulatory requirements), thereby reducing the impact on the coverage range.

[0092] For example, according to the priority information, it is determined that the transmit power of the data signal is preferentially reduced in the time window. If the average total transmit power after the transmit power of the data signal is reduced is still greater than the preset threshold, it is determined that the transmit power of the control signal is reduced. If the average total transmit power after the transmit power of the data signal and the control signal is reduced is still greater than the preset threshold, it is determined that the transmit power of the access signal is reduced.

[0093] For example, according to the priority information, it is determined that the transmit power of the data signal is preferentially reduced in the time window. If the average total transmit power after the transmit power of the data signal is reduced is still greater than the preset threshold, it is determined that the transmit power of the control signal is reduced. If the average total transmit power after the transmit power of the data signal and the control signal is reduced is less than or equal to the preset threshold, it is determined that the transmit power of the access signal is not reduced.

[0094] For example, according to the priority information, it is determined that the transmit power of the data signal is preferentially reduced in the time window. If the average total transmit power after the transmit power of the data signal is reduced is less than or equal to the preset threshold, it is determined that the transmit power of the control signal and the access signal is not reduced.

[0095] Optionally, in the case that the predicted average total transmit power is greater than the preset threshold, the transmit power of the data signal is reduced in the time window. In this optional scheme, the transmit power of the data signal is reduced, and the transmit power of the control signal and the access signal is not changed. The signal quality of the control signal and the access signal can be ensured from being degraded while the average total transmit power is less than or equal to the preset threshold (TRP meets the regulatory requirements), thereby reducing the impact on the user experience and the coverage range.

[0096] For example, the preset threshold is T, and the average total transmit power of the access signal above the horizontal plane in the time window is The average total transmit power of the control signal above the horizontal plane in the time window is the average transmit power above the level of the data signal in the time window is predicted to be the average transmit power above the level of the data signal in the time window is predicted to be

[0097] Optionally, the implementation manner of reducing the transmit power of the data signal comprises: reducing frequency domain resources used for transmitting the data signal, and / or, reducing time domain resources used for transmitting the data signal. Optionally, the implementation manner of reducing the transmit power of the data signal comprises: not reducing time-frequency resources used for transmitting the data signal, and directly reducing the transmit power of the data signal.

[0098] Exemplarily, in the case that the base station transmits the data signal to a terminal device far away, the transmit power of the data signal can be reduced by means of reducing resource blocks (RBs) used for transmitting the data signal. In the case that the base station transmits the data signal to a terminal device close by, the transmit power of the data signal can be reduced by means of directly reducing the transmit power of the data signal.

[0099] The following describes reducing the transmit power of the data signal in the time window in combination with specific examples.

[0100] Optionally, if the average transmit power above the level of the access signal in the first time unit is greater than a preset threshold, and / or, the average transmit power above the level of the control signal in the second time unit is greater than a preset threshold, the transmit power of the data signal is reduced in the third time unit, wherein the time window comprises the first time unit, the second time unit and the third time unit, the first time unit is used for transmitting the access signal, the second time unit is used for transmitting the control signal, and the third time unit is used for transmitting the data signal.

Exemplarily, if the average transmit power above the level of the access signal in the first time unit is greater than a preset threshold, and the average transmit power above the level of the control signal in the second time unit is greater than a preset threshold, the transmit power of the data signal is reduced in the third time unit.

[0102] Optionally, the fourth time unit is earlier than the third time unit, wherein the time window further comprises the fourth time unit, and the fourth time unit is used for transmitting the data signal; in this optional solution, the power can be transferred to the last time unit used for transmitting the data signal. FIG. 9 is a schematic diagram of a time window provided by an embodiment of the present application. It should be noted that the power can also be transferred to the first time unit used for transmitting the data signal, or to all time units used for transmitting the data signal in the time window, which is not limited herein.

[0103] Optionally, the priority of transmitting the data signal in the third time unit is lower than the priority of transmitting the data signal in the fourth time unit, wherein the time window further comprises the fourth time unit, and the fourth time unit is used for transmitting the data signal; in this optional solution, the power can be transferred to the time unit used for transmitting the data signal with the lower priority.

[0105] Optionally, any one of the first time unit, the second time unit, the third time unit and the fourth time unit can be used for transmitting at least one of the data signal, the control signal or the access signal. For example, different time units are different time slots, and different signals can be transmitted in different symbols of the same time unit.
