[0002] The fifth generation of mobile communication technology (5G) has introduced uplink transmission switching (UL Tx switching for short). This technology aims to address the current implementation limitations of handheld terminals, that is, the limitation that terminals only have two transmission channels, and has developed a mechanism for switching uplink transmission channels between different frequency bands. The terminal can first report its switching time between each pair of uplink frequency bands and the frequency band where the switching occurs, and the network side will schedule the terminal to perform uplink switching between the two frequency bands. Figure 1 As shown, the network side schedules the terminal to perform uplink switching and transmission between the two frequency bands, so that each frequency band can use two transmission channels for uplink dual transmission at each time.

[0080] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0081] In the related art, since the corresponding downlink in the uplink switching time cannot be transmitted in some frequency bands during the uplink switching time of the transmission channel, an indication of downlink interruption (which can be expressed as DL interruption in English) is introduced; the uplink switching time can be indicated by the user equipment (UE) through reporting capabilities, such as 35 microseconds (us), 140us, or 210us. In addition, the UE can also report capabilities to the network side, reporting whether there is a downlink interruption or not. In the case of a downlink interruption, the network side may not perform downlink scheduling within the downlink interruption time. Among them, the downlink interruption time specified in the related art is shown in Table 1. The downlink interruption time is in units of orthogonal frequency division multiplexing (OFDM) symbols, and the downlink interruption time is greater than the uplink switching time. The downlink interruption time can be calculated by formula (1), that is, the downlink interruption time can be calculated using the switching period (which can be expressed as switching period in English), the adjustment uncertainty (which can be expressed as adjustment uncertainty in English) parameter of the timing advance (TA), the relative time difference (RTD, Relative Time Discrepant), the cyclic prefix (CP, Cyclic Prefix) length (which can be expressed as length in English) and the symbol duration (which can be expressed as symbol duration in English).

[0084]

[0085] Table 1

[0086] In actual applications, there may be at least two reasons that cause downlink interruption during uplink switching:

[0087] Reason 1: RF architecture;

[0088] Reason 2: Downlink interference.

[0089] Among them, for the above reason 1, the implementation architecture of the terminal is mainly considered. For example, some time division duplexing (TDD, Time Division Duplexing) frequency bands with a relatively close range share a radio frequency channel; for example, Figure 2As shown, the low band (LB), mid band (MB) and high band (HB) usually share the radio frequency channel. For the frequency bands that share the radio frequency channel, one frequency band cannot perform downlink reception at the same time when performing uplink switching, which will cause downlink interruption.

[0090] In actual applications, as the number of frequency bands and frequency band combinations supported by the terminal increases, other reasons other than the RF architecture may cause downlink interruption during uplink switching, such as the above reason 2; at the same time, as the number of frequency bands supported by the terminal increases, if the terminal reports whether the switching between each pair of frequency bands in each frequency band combination causes downlink interruption, it will also increase signaling overhead. Figure 3 As shown, the downlink interference may include interference of uplink transmission on downlink reception due to harmonics and cross-band isolation (which may be expressed as cross band isolation in English), which may lead to reduced sensitivity at the receiving side and decreased receiving performance.

[0091] From the above description, it can be seen that in the related technology, when the terminal performs uplink switching, downlink interruption may occur, and downlink performance may be lost; and when the terminal performs uplink switching, the network side may not be able to reasonably schedule the terminal, and thus may not be able to guarantee the L1 measurement performance of the terminal, that is, the scheduling performance of the network side also needs to be improved. Therefore, it is necessary to enhance the uplink transmission mechanism of the terminal and the scheduling mechanism of the network side to avoid more downlink interruptions, reduce the loss of downlink performance, and improve the scheduling performance of the network side.

[0092] Based on this, in various embodiments of the present application, the terminal reports to the network side information indicating whether a downlink interruption occurs when the terminal performs an uplink switching and / or related information of downlink interference that occurs when the terminal performs an uplink switching. In this way, the network device can subsequently reasonably schedule the terminal based on the information indicating whether a downlink interruption occurs when the terminal performs an uplink switching and / or related information of downlink interference that occurs when the terminal performs an uplink switching, thereby ensuring the L1 measurement performance of low-cost terminals (such as handheld terminals with only two transmission channels, etc.) while minimizing BWP switching and measurement interval overhead, avoiding reselection failures, thereby improving the scheduling performance on the network side and reducing the loss of downlink performance.

[0093] Specifically, an embodiment of the present application provides an information transmission method, which is applied to a terminal, and the method includes:

[0094] The first information and / or the second information are sent to the network side, wherein the first information indicates whether a downlink interruption occurs when the terminal performs uplink switching, and the second information includes relevant information of downlink interference occurring when the terminal performs uplink switching.

[0095] In actual application, the terminal may also be referred to as a UE or a user.

[0096] In actual application, the first information may also be called interruption information or downlink interruption information, etc., and the second information may also be called interference information or downlink reception interference information, etc. The embodiment of the present application does not limit the names of the first information and the second information, as long as their functions are realized.

[0097] In actual application, the specific form in which the first information indicates whether a downlink interruption occurs when the terminal performs an uplink switch can be set according to needs, and the embodiment of the present application does not limit this. Exemplarily, the size of the first information can be 1 bit. When the first information contains 1, the first information indicates that a downlink interruption occurs when the terminal performs an uplink switch; when the first information contains 0, the first information indicates that no downlink interruption occurs when the terminal performs an uplink switch. Wherein, in the case where the first information indicates that a downlink interruption occurs when the terminal performs an uplink switch, the first information may also include the frequency band or carrier where the downlink interruption occurs, or the first information may only include the frequency band or carrier where the downlink interruption occurs, that is, the frequency band or carrier where the downlink interruption occurs is used to indicate that a downlink interruption occurs when the terminal performs an uplink switch.

[0098] In one embodiment, the downlink interference related information may include at least one of the following (that is, the second information may include at least one of the following):

[0099] third information, wherein the third information represents a change in downlink signal quality;

[0100] fourth information, wherein the fourth information indicates whether a downlink interruption associated with the downlink interference or a downlink interruption caused by the downlink interference occurs;

[0101] fifth information, where the fifth information represents a time when a downlink interruption associated with the downlink interference or a downlink interruption caused by the downlink interference occurs;

[0102] The sixth information represents a location where a downlink interruption associated with the downlink interference or a downlink interruption caused by the downlink interference occurs.

[0103] Here, it should be noted that the downlink interruption associated with the downlink interference and the downlink interruption caused by the downlink interference are equivalent concepts; in other words, the downlink interruption associated with the downlink interference refers to the downlink interruption caused by the downlink interference.

[0104] In actual application, the specific form of the third information representing the change in downlink signal quality can be set according to needs, such as a sensitivity backoff value (which may include a maximum sensitivity backoff decibel (dB) value) and / or a downlink signal quality reduction value (which may include a dB value), etc., which is not limited to the embodiments of the present application.

[0105] In actual application, the fourth information representing whether a downlink interruption associated with the downlink interference occurs or the specific form of the downlink interruption caused by the downlink interference can be set according to needs, such as a bit, etc., and the embodiment of the present application does not limit this.

[0106] In actual application, the specific form of the time when the fifth information represents the downlink interruption associated with the downlink interference or the downlink interruption caused by the downlink interference can be set according to needs, such as the number of interruption symbols (expressed as symbol in English) or the number of microseconds (us), etc., which is not limited to this in the embodiment of the present application.

[0107] In actual application, the specific form of the location of the sixth information representing the downlink interruption associated with the downlink interference or the downlink interruption caused by the downlink interference can be set according to needs, such as the downlink frequency band or carrier where the interference or interruption occurs, etc., and the embodiment of the present application does not limit this.

[0108] In actual application, the terminal may also report to the network side the reason for the downlink interruption when performing uplink switching.

[0109] Based on this, in one embodiment, the method may further include:

[0110] Sending seventh information to the network side, where the seventh information indicates a reason why a downlink interruption occurs when the terminal performs uplink switching.

[0111] The reasons may include at least one of the following:

[0112] Multiple frequency bands (i.e., at least two frequency bands) for uplink switching share one radio frequency channel;

[0113] The terminal generates downlink interference when performing uplink switching;

[0114] The type of downlink interference that occurs when the terminal performs uplink switching, such as harmonic interference and / or cross-band isolation, etc. When the downlink interference that occurs includes harmonic interference, the type of downlink interference may also reflect a specific harmonic interference order, such as second harmonic or third harmonic, etc.;

[0115] The target frequency band for uplink switching does not support simultaneous transmission and reception (which can be expressed as simultaneousTxRx in English).

[0116] In actual application, the specific form of the reason why the terminal has a downlink interruption when performing an uplink switch can be set according to the needs, and the embodiment of the present application does not limit this. Exemplarily, the cause value (which can be expressed as cause value in English) corresponding to each reason why the terminal has a downlink interruption when performing an uplink switch can be pre-configured on the terminal and the network side, and the seventh information can include the cause value corresponding to the reason why the terminal has a downlink interruption when performing an uplink switch. In addition, the reason why the terminal has a downlink interruption when performing an uplink switch can also include other reasons in addition to the above reasons, and the embodiment of the present application does not limit this.

[0117] In actual application, the terminal can also report the implementation information supported by itself to the network side, such as relevant information of the radio frequency architecture, so that the network side can judge (i.e. determine) whether a downlink interruption occurs when the terminal performs uplink switching, and / or determine the time when the downlink interruption occurs based on the implementation information supported by the terminal.

[0118] Based on this, in one embodiment, the method may further include:

[0119] Sending eighth information to the network side, where the eighth information is used to determine whether a downlink interruption occurs when the terminal performs uplink switching and / or the time when the downlink interruption occurs.

[0120] The eighth information may include at least one of the following:

[0121] The number of radio frequency channels of the terminal;

[0122] A correspondence between each radio frequency channel of the terminal and at least one frequency band, wherein each radio frequency channel corresponds to at least one frequency band;

[0123] The number of PLLs of the terminal;

[0124] The number of PLLs corresponding to each radio frequency channel of the terminal.

[0125] In actual application, the eighth information may also be referred to as terminal implementation information, etc. The embodiment of the present application does not limit the name of the eighth information, as long as its function is implemented.

[0126] In actual application, after the network side determines that the terminal has a downlink interruption when performing uplink switching using the eighth information, it can also determine the cause of the downlink interruption based on the eighth information (i.e., determine the seventh information). In addition, the network side can schedule the terminal according to at least one of the first information, the second information, the seventh information, and the eighth information, that is, determine the scheduling information of the terminal according to at least one of the first information, the second information, the seventh information, and the eighth information, and send the scheduling information to the terminal; after receiving the scheduling information, the terminal can perform uplink and / or downlink transmission according to the scheduling information.

[0127] Accordingly, an embodiment of the present application further provides an information transmission method, which is applied to a network device (such as a base station, etc.), and the method includes:

[0128] The first information and / or second information sent by the terminal is received, wherein the first information indicates whether a downlink interruption occurs when the terminal performs uplink switching, and the second information includes relevant information of downlink interference occurring when the terminal performs uplink switching.

[0129] In one embodiment, the method may further include:

[0130] Receive seventh information sent by the terminal, where the seventh information indicates a reason why a downlink interruption occurs when the terminal performs uplink switching.

[0131] In one embodiment, the method may further include:

[0132] Receive the eighth information sent by the terminal, and use the eighth information to determine whether a downlink interruption occurs when the terminal performs uplink switching, and / or determine the time when the downlink interruption occurs.

[0133] In one embodiment, the method may further include:

[0134] Scheduling the terminal according to at least one of the following:

[0135] the first information;

[0136] the second information;

[0137] The seventh information;

[0138] The eighth information.

[0139] Wherein, in actual application, the network device can schedule the terminal according to the first information and / or the second information. Exemplarily, if the first information indicates that a downlink interruption occurs when the terminal performs uplink switching, and at the same time, the fourth information in the second information represents that a downlink interruption occurs due to downlink interference, and the locations (i.e., frequency band or carrier, etc.) of the downlink interruption corresponding to the first information and the second information are the same, then the network device can schedule the terminal according to the downlink interruption with the longest duration among the above two downlink interruptions (i.e., the downlink interruptions corresponding to the first information and the second information, respectively).

[0140] If the first information indicates that a downlink interruption occurs when the terminal performs uplink switching, and at the same time, the fourth information in the second information represents a downlink interruption caused by downlink interference, and the locations of the downlink interruption corresponding to the first information and the second information are different (i.e., frequency bands or carriers, etc.), then the network device can schedule the terminal with corresponding interruption times in the corresponding frequency bands or carriers for the above two downlink interruptions, respectively.

[0141] If the first information indicates that no downlink interruption occurs when the terminal performs uplink switching, and at the same time, the fourth information in the second information represents that a downlink interruption occurs due to downlink interference, the network device may schedule the terminal at the location where the downlink interruption occurs indicated by the sixth information in the second information, using the interruption time indicated by the fifth information in the second information.

[0142] If the first information indicates that the terminal does not have a downlink interruption when performing an uplink switch, or when the first information and the second information correspond to different locations where a downlink interruption occurs, when the dB value (i.e., the value of sensitivity fallback or downlink signal quality reduction) indicated by the third information in the second information is greater than the first threshold, the network device can schedule the terminal at the corresponding location where the downlink interruption occurs using the corresponding interruption time according to the first information; when the dB value indicated by the third information in the second information is less than the second threshold, the network device can schedule the terminal normally, that is, the network device can ignore (or be understood as ignoring) the downlink interruption; when the dB value indicated by the third information in the second information is greater than the third threshold, the network device can schedule the terminal at the location where the downlink interruption occurs indicated by the sixth information in the second information using the interruption time indicated by the fifth information in the second information. Wherein, the first threshold, the second threshold, and the third threshold can be the same or different, and the specific values ​​and size relationship of the first threshold, the second threshold, and the third threshold can be preset by the network device.

[0143] In actual application, the network device may schedule the terminal according to at least one of the first information, the second information and the seventh information. Exemplarily, if the first information indicates that a downlink interruption occurs when the terminal performs an uplink switch, and the reason indicated by the seventh information includes that multiple frequency bands for uplink switching share a radio frequency channel, or that the target frequency band for uplink switching does not support simultaneous transmission and reception, then the network device may not schedule the terminal for downlink transmission at the corresponding location and interruption time of the downlink interruption according to the first information.

[0144] If the first information indicates that the terminal has a downlink interruption when performing an uplink switch, and the reason indicated by the seventh information includes downlink interference when the terminal performs an uplink switch, the network device can determine whether to schedule the terminal for downlink transmission within the interruption time according to the dB value represented by the third information in the second information (i.e., the value of sensitivity fallback or downlink signal quality reduction). Specifically, when the dB value represented by the third information in the second information is less than or equal to the fourth threshold, the network device can schedule the terminal for downlink transmission without considering the downlink interruption; when the dB value represented by the third information in the second information is greater than the fourth threshold, the network device can not schedule the terminal for downlink transmission. Among them, the fourth threshold can be the same as or different from the first threshold, the second threshold and the third threshold, and the specific value of the fourth threshold and the size relationship between the fourth threshold and the first threshold, the second threshold and the third threshold can be preset by the network device.

[0145] If the first information indicates that the terminal has a downlink interruption when performing an uplink switch, and the reason indicated by the seventh information includes the downlink interference and the type of downlink interference when the terminal performs an uplink switch, or only includes the type of downlink interference that occurs when the terminal performs an uplink switch, then the network device can determine whether to schedule the terminal for downlink transmission within the interruption time according to the type of downlink interference that occurs. Specifically, when the type of downlink interference is cross-band isolation, if the dB value represented by the third information in the second information (i.e., the value of sensitivity fallback or downlink signal quality reduction) is less than or equal to the fifth threshold, the network device can schedule the terminal for downlink transmission without considering the downlink interruption; if the dB value represented by the third information in the second information is greater than the fifth threshold, the network device may not schedule the terminal for downlink transmission. When the type of downlink interference is harmonic interference, the network device can avoid the interference position in the frequency domain through scheduling, or can schedule the terminal in the same scheduling mode as when the type of downlink interference is cross-band isolation (i.e., the scheduling mode based on the fifth threshold). Among them, the fifth threshold can be the same as or different from the first threshold, the second threshold, the third threshold and the fourth threshold, and the specific value of the fifth threshold and the size relationship between the fifth threshold and the first threshold, the second threshold, the third threshold and the fourth threshold can be pre-set by the network device.

[0146] In actual application, the network device can determine whether a downlink interruption occurs when the terminal performs uplink switching based on the terminal implementation information (i.e., the eighth information), and can determine the time when the downlink interruption occurs. Exemplarily, the network device can determine whether the two frequency bands share a radio frequency channel when the terminal performs uplink switching between two frequency bands based on the number of radio frequency channels of the terminal contained in the eighth information and the correspondence between each radio frequency channel and at least one frequency band, so as to determine whether a downlink interruption will be caused; when the two frequency bands do not share a radio frequency channel, the switching time can be determined based on the number of PLLs of the terminal and / or the number of PLLs corresponding to each radio frequency channel. The switching time required for switching between frequency bands that do not share a radio frequency channel but share a PLL is less than the switching time between frequency bands that share a radio frequency channel; based on the uplink switching time, the time when the downlink interruption occurs can be determined.

[0147] In actual application, the network device can schedule the terminal according to the second information and the eighth information, that is, the network device uses the eighth information to determine whether a downlink interruption occurs when the terminal performs an uplink switching, and after determining the time of the downlink interruption when the downlink interruption occurs, the determined information can be used in combination with the second information to schedule the terminal. Here, in the case where the terminal reports the eighth information to the network device, since the terminal does not need to inform the network of the interruption information (i.e., the first information) and / or interference information (i.e., the second information) of each pair of switching frequency bands, the network device can also use the eighth information to determine whether a downlink interruption occurs when the terminal performs an uplink switching, and determine the time of the downlink interruption when the downlink interruption occurs. Therefore, the signaling reporting of the interruption information can be reduced and the signaling overhead can be reduced. Exemplarily, if the eighth information is used to determine that a downlink interruption occurs when the terminal is performing uplink switching, and at the same time, the fourth information in the second information represents a downlink interruption caused by downlink interference, and the locations of the downlink interruption corresponding to the eighth information and the second information are the same (i.e., frequency band or carrier, etc.), then the network device can schedule the terminal according to the longest downlink interruption of the above two downlink interruptions (i.e., the downlink interruptions corresponding to the eighth information and the second information respectively).

[0148] If the eighth information is used to determine that a downlink interruption occurs when the terminal is performing uplink switching, and at the same time, the fourth information in the second information represents a downlink interruption caused by downlink interference, and the locations of the downlink interruption corresponding to the eighth information and the second information are different (i.e., frequency bands or carriers, etc.), then the network device can schedule the terminal with corresponding interruption times in corresponding frequency bands or carriers for the above two downlink interruptions, respectively.

[0149] If it is determined by using the eighth information that no downlink interruption occurs when the terminal performs uplink switching, and at the same time, the fourth information in the second information represents a downlink interruption caused by downlink interference, then the network device can schedule the terminal at the location where the downlink interruption occurs indicated by the sixth information in the second information, using the interruption time indicated by the fifth information in the second information.

[0150] If it is determined by using the eighth information that no downlink interruption occurs when the terminal performs uplink switching, or when the locations where the downlink interruption occurs corresponding to the eighth information and the second information are different, when the dB value represented by the third information in the second information (i.e., the value of sensitivity fallback or downlink signal quality reduction) is greater than the first threshold, the network device may use the corresponding interruption time to schedule the terminal at the location where the downlink interruption occurs determined by using the eighth information; when the dB value represented by the third information in the second information is less than the second threshold, the network device may schedule the terminal normally, i.e., the network device may not consider (or may be understood to ignore) the downlink interruption; when the dB value represented by the third information in the second information is greater than the third threshold, the network device may use the interruption time indicated by the fifth information in the second information at the location where the downlink interruption occurs indicated by the sixth information in the second information to schedule the terminal.

[0151] In actual application, when the network device schedules the terminal, it can determine the scheduling information of the terminal according to the first information, the second information, the seventh information, and at least one of the eighth information, and send the scheduling information to the terminal; after the terminal receives the scheduling information, it can perform uplink and / or downlink transmission according to the scheduling information.

[0152] Accordingly, the present application also provides an information transmission method, such as Figure 4 As shown, the method includes:

[0153] Step 401: The terminal sends first information and / or second information to a network device, wherein the first information indicates whether a downlink interruption occurs when the terminal performs uplink switching, and the second information includes relevant information of downlink interference occurring when the terminal performs uplink switching;

[0154] Step 402: The network device receives the first information and / or second information sent by the terminal.

[0155] In the information transmission method provided by the embodiment of the present application, the terminal sends the first information and / or the second information to the network side, the first information indicates whether the terminal has a downlink interruption when performing an uplink switch, and the second information includes the relevant information of the downlink interference that occurs when the terminal performs an uplink switch. In the scheme provided by the embodiment of the present application, the terminal reports to the network side information indicating whether a downlink interruption occurs when the terminal performs an uplink switch and / or relevant information of the downlink interference that occurs when the terminal performs an uplink switch, so that the network device (such as a base station, etc.) can subsequently reasonably schedule the terminal according to the information indicating whether a downlink interruption occurs when the terminal performs an uplink switch and / or relevant information of the downlink interference that occurs when the terminal performs an uplink switch, thereby ensuring the L1 measurement performance of low-cost terminals (such as handheld terminals with only two transmission channels, etc.) under the condition of minimizing BWP switching and measurement interval overhead, avoiding reselection failures, thereby improving the scheduling performance of the network side and reducing the loss of downlink performance.

[0156] In addition, the solution provided in the embodiment of the present application combines the downlink interruption caused by new interference in the uplink switching (such as harmonic interference and / or cross-frequency band isolation, etc.) and the original downlink interruption (such as the downlink interruption caused by multiple frequency bands sharing a radio frequency channel for uplink switching, etc.), and the terminal can report to the network side the location of the interruption impact (i.e., the location of the downlink interruption), the cause of the interruption, the degree of interference causing the interruption, the type of interference causing the interruption and other information to assist the network device in reasonably determining how to schedule the terminal; in other words, the terminal reports at least one of the above-mentioned first information, second information, seventh information and eighth information to the network side to assist the network device in determining how to schedule the terminal, and can provide sufficient auxiliary information for the network side to reasonably schedule the terminal.

[0157] In addition, the solution provided in the embodiment of the present application can reduce the signaling reporting of the interruption information (ie, the first information) and reduce the signaling overhead in some scenarios, such as when the terminal reports the second information and the eighth information.
