In this system, how to implement processing of multiple signals, for example, to implement beam selection, is a problem to be solved for the terminal device.

Disclosure of Invention

The embodiment of the application provides a method and equipment for processing signals, which can realize the selection of beams according to the measurement results of a plurality of signals.

In a first aspect, a method for processing a signal is provided, including:

the terminal equipment measures N downlink signals to obtain N measurement results, wherein N is an integer greater than 1;

determining a first transmission quality comparison result of a first downlink signal and a second downlink signal according to a first measurement result and a second measurement result in the N measurement results and a first adjustment amount corresponding to the first measurement result and the second measurement result, wherein the first downlink signal is a downlink signal corresponding to the first measurement result in the N downlink signals, and the second downlink signal is a downlink signal corresponding to the second measurement result in the N downlink signals;

determining K downlink signals from the N downlink signals according to at least one transmission quality comparison result, wherein the at least one measurement result comprises the first transmission quality comparison result, each transmission quality comparison result in the at least one transmission quality comparison result is a comparison result of transmission quality of two downlink signals in the N downlink signals, and 1< K < N;

and sending the information of the K downlink signals to network equipment.

Therefore, in the method for processing signals according to the embodiment of the present application, the terminal device does not directly compare the measurement results of the two downlink signals to determine the quality of the transmission quality of the two downlink signals, but determines the transmission quality comparison result of the two downlink signals by combining the adjustment amounts corresponding to the measurement results of the two downlink signals when comparing the measurement results of the two downlink signals, so that the selection of the beam according to the adjusted transmission quality comparison result can be realized, and further, when selecting the beam according to the adjusted transmission quality comparison result, the probability of selecting the beam can be adjusted.

As a possible implementation manner, the terminal device may determine, for the N measurement results, a transmission quality comparison result of each two downlink signals in the N downlink signals by combining the adjustment amounts corresponding to each two downlink signals. The comparison result of the transmission quality of every two downlink signals can be used to indicate the quality of the transmission quality between every two downlink signals in the N downlink signals, so that the terminal device can sequence the transmission quality of the N downlink signals. In one step, the terminal device may select a certain number of downlink signals with better transmission quality from the N downlink signals according to the transmission quality of the N downlink signals, and since different downlink signals are transmitted using different beams, the terminal device may determine a beam for transmitting the downlink signal according to the downlink signals, so that the terminal device may report information of the beam corresponding to the selected downlink signal with better transmission quality to the network device.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

It should be understood that the solution of the present invention can be applied to various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an Advanced Long Term Evolution (LTE-a) System, a Universal Mobile Telecommunications System (UMTS), 5G, and the like.

Fig. 1 illustrates a wireless communication system 100 suitable for use with embodiments of the present invention. The wireless communication system 100 may include at least one network device, such as the first network device 110 and the second network device 120 shown in fig. 1. First network device 110 and second network device 120 may each communicate with terminal device 130 over a wireless air interface. First network device 110 and second network device 120 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area. The first network device 110 or the second network device 120 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB) in a WCDMA system, an evolved Node B (eNB) or an eNodeB) in an LTE system, or a network device in a future 5G network, such as a Transmission Point (TRP), a Base Station, a small Base Station device, and the like, which is not particularly limited in this embodiment of the present invention.

The wireless communication system 100 further includes one or more terminal Equipment (UE) 130 located within the coverage area of the first network Equipment 110 and the second network Equipment 120. The terminal device 130 may be mobile or stationary. Terminal device 130 may communicate with one or more Core networks (Core networks) via a Radio Access Network (RAN), which may be referred to as an Access terminal, a terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The 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 function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, and the like.

In the communication system, the network device can transmit different CSI-RS or SS blocks by using different beams, and the terminal device can distinguish different beams according to the different SS blocks or CSI-RS or resources used for transmitting the CSI-RS.

In the communication system, a terminal device may measure some downlink signals, for example, signals in CSI-RS or SS block, determine which signals have better transmission quality according to the measurement result, or determine which signals have better transmission quality for beai transmitting the signals, and report information about the determined beams to a network device, for example, the terminal device may measure N signals, select an optimal K signals, and report information about the K signals to the network device, where N is an integer and 1< ═ K < N.

However, in an actual network, the transmission power corresponding to different cells, for example, macro stations or small base stations (small cells) is different, and the transmission power of macro stations is often greater than the transmission power corresponding to small cells, so that beams with better transmission quality are determined directly according to the measurement result of each signal, and the probability that the beams used by the small cells are selected is always lower than that of the beams used by the macro stations.

In view of this, embodiments of the present disclosure provide a method for processing signals, which can process a plurality of signals according to measurement results of the plurality of signals and by combining with an adjustment amount, thereby implementing selection of a beam.

Fig. 2 is a schematic flow chart of a method 200 for processing a signal according to an embodiment of the present application, where the method 200 may be performed by a terminal device in the wireless communication system shown in fig. 1, and as shown in fig. 2, the method 200 includes:

s210, the terminal device measures the N downlink signals to obtain N measurement results, wherein N is an integer greater than 1.

In this embodiment of the application, the N downlink signals may be CSI-RS or signals in SS block, and for example, may include at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSs), a Physical Broadcast Channel (PBCH), and a Demodulation Reference Signal (DMRS) for demodulating PBCH, which is not limited in this embodiment.

That is to say, the N downlink signals may all be CSI-RS, or may all be SSS, or may all be PSS and SSS, or some signals are CSI-RS and some signals are SSS, and the like, which is not limited in this embodiment.

It should be noted that the N measurement results may be obtained after filtering (L1) and/or L3, for example, the measurement results may be measurement results that can be used for transmission quality comparison, such as Reference Signal Received Power (RSRP) of L1, or RSRP of layer 3, and the embodiment of the present invention is not limited thereto.

And S220, determining a first transmission quality comparison result of the first downlink signal and the second downlink signal according to the first measurement result and the second measurement result in the N measurement results and a first adjustment amount corresponding to the first measurement result and the second measurement result.

The first downlink signal is a downlink signal corresponding to the first measurement result in the N downlink signals, and the second downlink signal is a downlink signal corresponding to the second measurement result in the N downlink signals.

It should be noted that, in the embodiment of the present application, the first adjustment value corresponding to the first measurement result and the second measurement result is used to adjust the comparison value of the measurement results of the first downlink signal and the second downlink signal, that is, the adjustment value corresponding to the first measurement result and the second measurement result is used to adjust the comparison result of the transmission quality of the two downlink signals, in other words, in the prior art, the measurement results of the two downlink signals are directly compared to determine the transmission quality of the two downlink signals, and in the embodiment of the present application, on the basis of the comparison result of the measurement results of the two downlink signals, the comparison result is further adjusted by combining the first adjustment amount, so as to determine the comparison result of the transmission quality of the two downlink signals.

Specifically, if the terminal device wants to select K downlink signals from N downlink signals, it needs to compare the transmission quality of the N downlink signals, and determine K downlink signals satisfying the condition from the N downlink signals according to the comparison result of the transmission quality between two downlink signals. For example, the terminal device may compare the transmission quality of the first downlink signal and the second downlink signal, determine whether the transmission quality of the first downlink signal and the second downlink signal is good or bad, the terminal device may determine a first transmission quality comparison result of the first downlink signal and the second downlink signal by combining a difference between the first measurement result and the second measurement result with a first adjustment amount corresponding to the first measurement result and the second measurement result, or, the comparison result of the first measurement result and the second measurement result is adjusted according to the first adjustment amount, and the adjusted comparison result is determined as the first transmission quality comparison result, that is, the first adjustment amount may be regarded as an adjustment amount of a comparison result of the first measurement result and the second measurement result.

Therefore, in the method for processing signals according to the embodiment of the present application, the terminal device does not directly compare the measurement results of the two downlink signals to determine the quality of the transmission quality of the two downlink signals, but determines the transmission quality comparison result of the two downlink signals by combining the adjustment amounts corresponding to the measurement results of the two downlink signals when comparing the measurement results of the two downlink signals, and implements selection of beams according to the transmission quality comparison result, and on the other hand, performs beam selection according to the adjusted transmission quality comparison result to adjust the probability of beam selection.

It should be understood that the K downlink signals selected from the N downlink signals may be K signals with the best transmission quality, or may also be K signals with poor transmission quality, or may also be K downlink signals meeting other conditions, and the embodiment of the present application does not limit the selection conditions of the K downlink signals, and the embodiment of the present application only takes the selection of the K signals with the best transmission quality from the N downlink signals as an example for description, and should not be limited in any way.

For example, if the first downlink signal is a downlink signal corresponding to a low power cell, and the second downlink signal is a downlink signal corresponding to a high power cell, such that a difference between the first measurement result and the second measurement result is a negative value, and a difference between the first measurement result and the second measurement result is often large, that is, a difference between transmission quality of the first downlink signal and transmission quality of the second downlink signal is large, when the difference between the first measurement result and the second measurement result is adjusted by using a first adjustment amount, a positive adjustment amount may be added on the basis of the difference between the first measurement result and the second measurement result, so that a difference between measurement results of the first downlink signal and the selected second downlink signal can be reduced, that is, a difference between transmission quality of the first downlink signal and transmission quality of the second downlink signal is reduced, so that when beam selection is performed, it is advantageous to increase the probability that the beam of the low power cell is selected.

For example, downstream signal 1(Sig1) and downstream signal 2(Sig2) correspond to the measurement result X₁And X₂The comparison value of the measurement results of Sig1 and Sig2 is X₁-X₂The prior art is directly based on X₁-X₂The quality of the transmission quality of the sigs 1 and the sigs 2 is determined, and in the embodiment of the application, the measured result comparison value of the sigs 1 and the sigs 2 can be further combined with the adjustment value delta X corresponding to the sigs 1 and the Sig2, namely the measurement result comparison value of the adjustment value delta X corresponding to the sigs 1 and the sigs 2 is determined for the X₁-X₂The adjustment is carried out to obtain the transmission quality comparison result of Sig1 and Sig2, namely X₁-X₂+ Δ X or X₁-X₂- Δ x, where Δ x may be positive or negative, or of course zero.

Then, the terminal device may determine which downstream signal of Sig and Sig2 has the better transmission quality according to the transmission quality comparison result of Sig1 and Sig2, if X is₁-X₂Greater than zero, it can be determined in the prior art that the transmission quality of Sig1 is better than that of Sig2, otherwise it is determined that the transmission quality of Sig2 is better than that of Sig1, i.e., in the prior art, the transmission quality comparison result is X₁-X₂. In the embodiment of the present application, the transmission quality comparison results of Sig1 and Sig2 are X to X according to the adjustment values Δ X corresponding to Sig1 and Sig2₁-X₂As a result of the adjustment, the transmission quality comparison results of Sig1 and Sig2 are changed from the prior art, that is, the probability that the corresponding beams of Sig1 and Sig2 are selected is changed.

Alternatively, if the sign of Δ X is equal to X₁-X₂Of opposite sign, the comparison result of the transmission quality of the adjusted Sig1 and Sig2 may be X₁-X₂+ Δ X, or if the sign of Δ X is equal to X₁-X₂Are the same, the comparison result of the transmission quality of the adjusted Sig1 and Sig2 may be X₁-X₂Δ x, that is, the first adjustment amount is such that the absolute value of the measurement result comparison values of Sig1 and Sig2 is larger than the absolute value of the transmission quality comparison results of Sig1 and Sig2, that is, the difference in transmission quality between Sig1 and Sig2 is reduced. If Sig1 is the downlink signal transmitted by the low power cell and Sig2 is the downlink signal transmitted by the high power cell, X is the downlink signal transmitted by the low power cell in most cases₂＞X₁Therefore, the beam is directly selected according to the measurement results of Sig1 and Sig2, the probability that the beam corresponding to Sig2 is selected is much greater than that of the beam corresponding to Sig1, and if the measurement result comparison value is adjusted according to the adjustment value corresponding to Sig1 and Sig2 on the basis of the measurement result comparison values of Sig1 and Sig2, the transmission quality comparison results of Sig1 and Sig2 are obtained, which is equivalent to reducing the transmission quality comparison results between Sig1 and Sig2, that is, reducing the difference between the transmission qualities of Sig1 and Sig2, so that the probability that the beam corresponding to Sig1 is selected can be improved when the beam is selected according to the transmission quality comparison results of Sig1 and Sig 2.

It should be noted that the adjustment amounts corresponding to the two measurement results may be determined by the terminal device according to a large amount of measurement data, or may also be configured by the network device, which is not limited in this embodiment of the application, and the adjustment amounts corresponding to the two measurement results may also be adjusted according to actual situations, for example, in a certain time period, the adjustment amounts corresponding to the two measurement results are a first value, in another time period, the adjustment amounts corresponding to the two measurement results may be a second value, and the first value and the second value may be the same or different.

Optionally, in an embodiment of the present application, the method further includes:

It should be noted that, here, the first adjustment information may be considered as configured by the network device, and the first adjustment information may be used to determine the first adjustment amount, for example, the first adjustment information may be directly the first adjustment amount, that is, the first adjustment information is an adjustment amount of the measurement result for the first downlink signal and the second downlink signal. Alternatively, the terminal device may process the first adjustment information and determine the processed first adjustment information as the first adjustment amount, for example, the first adjustment information may be in a functional relationship with the first adjustment amount, the first adjustment information may be denoted as M, the first adjustment amount may be denoted as M, and the first adjustment information and the first adjustment amount may have the following relationship: and m ═ f (m), so that the terminal equipment can determine the first adjustment amount by substituting the first adjustment information into a function. Or the first adjustment information and the first adjustment amount may have a corresponding relationship, and the corresponding relationship may be in the form of a table, so that the terminal device may determine the first adjustment amount by combining the corresponding relationship according to the first adjustment information.

Optionally, the first adjustment information may include adjustment information corresponding to the first downlink signal and the second downlink signal, where the adjustment information corresponding to each downlink signal may be the transmission power of each downlink signal, or may also be an adjustment amount corresponding to each downlink signal, and the adjustment amount may be used to adjust the measurement result of each downlink signal, so as to obtain an adjusted measurement result.

In this embodiment, the first adjustment information is information of transmission powers of the first downlink signal and the second downlink signal.

That is, the first adjustment information may include information of the transmission power of the first downlink signal and information of the transmission power of the second downlink signal, the information of the transmission power of the first downlink signal may be regarded as pad information corresponding to the first downlink signal, and the information of the transmission power of the second information may be regarded as adjustment information corresponding to the second downlink signal.

Here, the information of the transmission power of the first downlink signal and the second downlink signal is information relative to the transmission power, such as an absolute value, a relative value, or rank information of the transmission power of the first downlink signal and the second downlink signal.

For example, the absolute value of the transmission power of the first downlink signal may be used as a reference value, so that the information about the transmission power of the other signals may be a relative value with respect to the absolute value of the transmission power of the first downlink signal, and the information about the transmission power of the first downlink signal is zero; or, a specific transmission power value may be used as a reference value, and the information of the transmission powers of the N downlink signals may be a relative value with respect to the specific transmission power value. Or the absolute value of the transmission power may be divided into a plurality of levels, and the information of the transmission power of each downlink signal may be a level corresponding to the absolute value of the transmission power of each downlink signal.

As an embodiment, in a case that the first adjustment information is information of transmission powers of the first downlink signal and the second downlink signal, the processing the first adjustment information, and determining the processed first adjustment information as the first adjustment amount includes:

For example, the terminal device may determine the first adjustment amount according to the transmission powers of the first downlink signal and the second downlink signal in combination with the first corresponding relationship, and optionally, the terminal device may first make a difference between the transmission powers of the first downlink signal and the second downlink signal, and determine, according to the transmission power difference and in combination with the first corresponding relationship, the adjustment amount corresponding to the transmission power difference as the first adjustment amount. Or the terminal device may determine, according to the transmission powers of the first downlink signal and the second downlink signal, the adjustment amounts corresponding to the transmission powers of the two downlink signals in combination with the first corresponding relationship, then may determine the difference between the adjustment amounts corresponding to the transmission powers of the two downlink signals, and determine the difference between the adjustment amounts as the first adjustment amount.

That is to say, the first corresponding relationship may be a corresponding relationship between a transmission power difference and an adjustment amount, or the first corresponding relationship may also be a corresponding relationship between a transmission power and an adjustment amount, so that the terminal device may determine a corresponding adjustment amount by first making a difference between transmission powers and then combining the first corresponding relationship, or the terminal device may determine an adjustment amount corresponding to each transmission power by first combining the first corresponding relationship, then making a difference between adjustment amounts, and then determining a difference between adjustment amounts as the first adjustment amount.

It should be understood that, in the embodiment of the present application, the first corresponding relationship may be in the form of a table or a tree, which is not limited in the embodiment of the present application.

For example, the first correspondence may be as shown in table 1.

TABLE 1

Adjustment value Deltax	Difference in transmission power
		Z₁	(Y₁，Y₂)
Z₂	(Y₂，Y₃)
		Z₃	(Y₃，Y₄)
...	...
		Z_L	(Y_L，Y_L+1)

That is, the difference in transmission power can be segmented, and each segment corresponds to a corresponding adjustment amount, for example, as shown in table 1, when the difference in transmission power between two downlink signals falls into (Y)₁，Y₂) Then, the corresponding adjustment amount can be determined as Z₁When the difference of the transmission power of the two downlink signals falls into (Y)₂，Y₃) Then, the corresponding adjustment amount can be determined as Z₂When the other segments fall into the corresponding adjustment amount, the adjustment amount is not listed.

In the correspondence shown in Table 1, segment (Y)₁，Y₂) Corresponding adjustment Z₁Segment (Y)₂，Y₃) Corresponding adjustment Z₂When the difference between the transmission power of the first downlink signal and the transmission power of the second downlink signal falls within (Y)₁，Y₂) When the difference value of the transmission power of the first downlink signal and the transmission power of the second downlink signal is recorded as a first difference value, the difference value of the transmission power of the first downlink signal and the transmission power of the second downlink signal falls into (Y)₂，Y₃) In the process, the difference between the transmission powers of the first downlink signal and the second downlink signal is recorded as a second difference, so that the first difference is smaller than the second difference, and a large transmission power usually means that the measurement result corresponding to the signal is large, and then a small difference between the transmission powers of the two downlink signals means that the adjustment amount to be compensated is small, and if the difference between the measurement results of the two downlink signals is to be reduced, a segment (Y) can be set₁，Y₂) Corresponding adjustment Z₁Less than segment (Y)₂，Y₃) Corresponding adjustment Z₂That is, when the difference between the transmission powers is small, the difference between the measurement results is small, and therefore the measurement results of the two downlink signals can be adjusted by using a small adjustment amount.

It should be noted that the correspondence shown in table 1 is only an example and is not limited, for example, the number of segments used in the first correspondence and the adjustment amount corresponding to each segment may be adjusted according to actual situations, and the embodiment of the present application does not limit a specific correspondence.

As another embodiment, the processing the first adjustment information and determining the processed first adjustment information as the first adjustment amount includes:

The first function may be a linear function or a nonlinear function, and for example, the first function may be f (x) kx, or the first function may be f (x) kx²And the like, where k is a constant, x is an argument, and k may be a positive number or a negative number, an integer, or a fraction, and a result obtained by substituting the information of the transmission powers of the first downlink signal and the second downlink signal into the first function is the first adjustment amount.

Optionally, the first function f (x) ax, the first adjustment amount is a (P)₂-P₁) Or a (P)₁-P₂) Wherein a is a constant, x is an independent variable, and P is₁Information of the transmission power of the first downlink signal, P₂And the information is the transmission power information of the second downlink signal.

If the measurement result of the first downlink signal is X₁The measurement result of the second downlink signal is X₂The difference between the transmission power of the first downlink signal and the transmission power of the second downlink signal is P₁-P₂The first adjustment amount Δ x is a (P)₂-P₁) Or a (P)₁-P₂) And a may be 1, a number greater than 1, or a number less than 1, and then the comparison result of the transmission quality of the first downlink signal and the second downlink signal may be X₁-X₂+Δx。

Specifically, if a is greater than zero, the first adjustment amount may be a (P)₂-P₁) The terminal device may determine a difference between the first measurement result and the second measurement result, and a result obtained by adding the first adjustment amount to the difference as the first transmission quality comparison result, that is, the first transmission quality comparison result is X₁-X₂+a(P₂-P₁) (ii) a Or

If a is less than zero, the first adjustment amount may be a (P)₁-P₂) The terminal device may determine a difference between the first measurement result and the second measurement result, and a result obtained by adding the first adjustment amount to the difference, as the first transmission quality comparison result, that is, the first transmission quality comparison result is X₁-X₂+a(P₁-P₂)。

Because the measurement result corresponds to the transmission power, the transmission power is large, and often corresponds to the measurement result, if the transmission power of the first downlink signal is greater than the transmission power of the second downlink signal, the first measurement result is often greater than the second measurement result, and then the first adjustment quantity may be opposite in sign to the difference between the first measurement result and the second measurement result, so that the first adjustment quantity may cancel part of the difference between the measurement results, and the purpose of reducing the difference between the transmission qualities of the first downlink signal and the second downlink signal is achieved, thereby improving the probability that the beam corresponding to the second downlink signal is selected when the beam selection is performed.

That is to say, the first adjustment amount may make the absolute value of the difference between the measurement results of the two downlink signals greater than the absolute value of the comparison result of the transmission qualities of the two downlink signals, so that, after the adjustment, the difference between the transmission quality of the signal of the low-power cell and the transmission quality of the signal of the high-power cell is reduced, and therefore, when performing beam selection, the probability that the beam of the low-power cell is selected can be improved.

Optionally, in this embodiment of the present application, the a may be configured by a system, or the a is agreed by a protocol.

In the embodiment of the present application, the agreement may include pre-configuration on the terminal device, and system configuration is not required.

Optionally, in some embodiments, the method further comprises:

and the terminal equipment receives configuration information sent by the network equipment, wherein the configuration information comprises the first adjustment information.

The first adjustment Information corresponds to the first adjustment Information described above, and optionally, the network device may send the configuration Information to the terminal device through Radio Resource Control (RRC) signaling, or the network device may also send the configuration Information to the terminal device through Downlink Control Information (DCI).

In this embodiment of the present application, the configuration information includes adjustment information corresponding to each downlink signal, or the first configuration information includes adjustment information of a group of downlink signals, where the group of downlink signals includes some or all of the N downlink signals, and if the configuration information does not include the adjustment information of the first downlink signal or the second downlink signal, the adjustment information of the first downlink signal or the second downlink signal adopts a default value.

That is to say, the network device may configure corresponding adjustment information for each downlink signal in the N downlink signals, or the network device may also configure corresponding adjustment information for a part of the N downlink signals, and a default value may be used for a downlink signal without corresponding adjustment information, where the default value may be a zero value, or may be a positive value, or may be a negative value, and the default values corresponding to different downlink signals may be the same or different, and the default value may be a protocol convention or a system configuration.

The adjustment information corresponding to each downlink signal may be information of transmission power corresponding to each downlink signal, or an adjustment amount corresponding to each downlink signal, where the adjustment amount corresponding to each downlink signal may be used to adjust a measurement result of each downlink signal.

Or the network device may also configure corresponding adjustment information for a group of downlink signals, that is, a group of downlink signals may correspond to the same adjustment information, where the adjustment information may be an adjustment amount, that is, a group of downlink signals may correspond to one adjustment amount, and another group of downlink signals may correspond to another adjustment amount.

Optionally, in this embodiment of the present application, the adjustment information corresponding to the N downlink signals is N adjustment amounts corresponding to the N downlink signals, or indexes of the N adjustment amounts in a preconfigured adjustment amount set;

For example, the network device may configure a corresponding adjustment amount for each downlink signal, where the adjustment amount may be used to adjust the measurement result of each downlink signal to obtain an adjusted measurement result, and the adjustment amount corresponding to each of the N downlink signals is offset, for example₁，offset₂，...，offset_NThe measurement result corresponding to the N downlink signals is X₁，X₂，...，X_NThe adjusted measurement result of each downlink signal may then be X₁+offset₁，X₂+offset₂，...，X_N+offset_1NOr the adjusted measurement result of each downlink signal may be X₁-offset₁，X₂-offset₂，...，X_N-offset_1N。

From another perspective, the adjustment amount of the first downlink signal and the second downlink signal may be offset₁-offset₂Or offset₂-offset₁That is, the adjustment amount corresponding to the measurement result of the two downlink signals can be determined according to the adjustment amount corresponding to each of the two downlink signals

Further, S220 may include:

That is, the first adjustment amount may be used to offset a part of a difference between the first measurement result and the second measurement result, or the first adjustment amount may enable an absolute value of the first transmission quality comparison result to be smaller than an absolute value of a difference between the first measurement result and the second measurement result, that is, the embodiment of the present application may reduce a difference between transmission qualities of signals of the low power cell and the high power cell, so that when performing beam selection, a probability that a beam of the low power cell is selected may be improved.

S230, determining K downlink signals from the N downlink signals according to at least one transmission quality comparison result, where the at least one measurement result includes the first transmission quality comparison result, and each of the at least one transmission quality comparison result is a comparison result of transmission qualities of two downlink signals in the N downlink signals, and 1 ≦ K < N.

Therefore, the terminal device may perform transmission quality comparison on other signals in the N downlink signals according to the method for performing transmission quality comparison on the first downlink signal and the second downlink signal, so as to determine the K downlink signals from the N downlink signals.

Optionally, the terminal device may compare transmission quality of every two downlink signals in the N downlink signals, and determine a result of comparing transmission quality of any two downlink signals, so as to determine K downlink signals in the N downlink signals according to the result of comparing transmission quality of any two downlink signals. That is, the terminal device may determine, according to the comparison result of the transmission quality of every two downlink signals, whether the transmission quality between every two downlink signals in the N downlink signals is good or bad, so as to sequence the transmission quality of the N downlink signals, and select K downlink signals from the N downlink signals according to the sequencing condition of the transmission quality of the N downlink signals.

Or the terminal device may also adjust an algorithm for comparing the transmission quality of the N downlink signals according to an actual situation, and as long as the measurement result is adjusted by combining the adjustment amount according to the measurement result of the two downlink signals when the transmission quality of the two downlink signals is compared, so as to determine the transmission quality comparison result, the method and the terminal device fall within the protection scope of the embodiment of the present application.

For example, the N downstream signals include downstream signal 1(Sig1), downstream signal 2(Sig2), and downstream signal 3(Sig3), which correspond to the measurement result X respectively₁，X₂，X₃Said X is₁And X₂Corresponding adjustment amount is Deltax₁，X₁And X₃Corresponding adjustment amount is Deltax₂，X₂And X₃Corresponding adjustment amount is Deltax₃When transmission quality comparison is performed, X may be compared₁-X₂+Δx₁Determined as a result of the comparison of the transmission quality of Sig1 and Sig2, if X₁-X₂+Δx₁Above zero, it may be determined that the transmission quality of Sig1 is better than Sig2, otherwise, it may be determined that the transmission quality of Sig2 is better than Sig 1. Similarly, the transmission quality comparison result of Sig1 and Sig3 may be determined to be X₁-X₃+Δx₂The transmission quality comparison result between Sig2 and Sig3 is X₂-X₃+Δx₃If it is necessary to select 1 signal with the best transmission quality from the 3 signals, the transmission qualities of Sig1 and Sig2 may be compared first, if it is determined that the transmission quality of Sig1 is better than that of Sig2, the transmission qualities of Sig1 and Sig3 may be compared further, if it is determined that the transmission quality of Sig3 is better than that of Sig1, it may be determined that the selected signal is Sig3, otherwise, it is determined that the selected signal is Sig1, and therefore, it is not necessary to compare the transmission qualities of Sig2 and Sig3 to select a signal that meets the requirements.

For another example, if 2 downlink signals with the optimal transmission quality need to be determined in 4 downlink signals, where the N downlink signals include Sig1, Sig2, Sig3, and Sig4, the terminal device may compare transmission qualities of Sig1 with Sig2, Sig3, and Sig4 in sequence, determine a signal with the optimal transmission quality in the four signals, and mark the signal with the optimal transmission quality as Sig1, and then the terminal device may compare Sig2 with Sig3 and Sig4 in sequence, and determine downlink information with the optimal transmission quality in the three downlink signals, so that two downlink signals with the optimal transmission quality in the 4 downlink signals may be determined.

It should be understood that, in S230, an algorithm for determining K signals satisfying a certain condition from the N downlink signals may be adjusted according to actual conditions, the above-listed algorithms are only for convenience of understanding the embodiment of the present application, and are not limited to the above-described specific algorithms, and the embodiment of the present application may use some sorting algorithms in the prior art to sort the transmission quality of the N downlink signals.

And S240, sending the information of the K downlink signals to the network equipment.

Optionally, S240 may include:

Here, the identification information of the K downlink signals may be information of beams corresponding to the K downlink signals, for example, a beam identification (identity, ID), or the terminal device may number the N downlink signals, where the identification information corresponding to the K downlink signals may be the numbers of the K downlink signals, or the identification information of the K downlink signals may also be other identification information for identifying each of the K downlink signals, which is not limited in this embodiment of the application.

The terminal device may further send K measurement results corresponding to the K downlink signals to the network device, where the K measurement results may also be used for the network device to further select the K downlink signals and determine a beam used for downlink transmission.

Since the network device may configure a corresponding adjustment amount for each downlink signal, and the adjustment amount may be used to adjust the measurement result of each downlink signal, so as to determine the adjusted measurement result of each downlink signal, the terminal device may calculate the adjusted measurement result of each downlink signal, and the measurement result reported to the network device by the terminal device may also be the adjusted measurement result corresponding to the K downlink signals.

Therefore, in the method for processing signals according to the embodiment of the present application, the terminal device does not directly compare the measurement results of the two downlink signals to determine the quality of the transmission quality of the two downlink signals, but determines the transmission quality comparison result of the two downlink signals by combining the adjustment amounts corresponding to the measurement results of the two downlink signals when comparing the measurement results of the two downlink signals, so that the selection of the beam according to the adjusted transmission quality comparison result can be implemented, and further, when selecting the beam, the selection of the beam according to the adjusted transmission quality comparison result can be implemented, and the probability of the selected beam can be adjusted
