[0003] Currently, commercial handheld terminals only have the ability to transmit up to 2 streams in the uplink and are configured in at most two frequency bands, and cannot flexibly utilize all uplink spectrum resources. Summary of the Invention

[0004] One technical problem to be solved by the present disclosure is to provide an uplink signal transmission method, a terminal, and a storage medium, which can improve the utilization rate of spectrum resources.

[0005] According to one aspect of the present disclosure, an uplink signal transmission method is proposed. Among them, the terminal is configured in at least three frequency bands, and the method includes: transmitting an uplink signal in one or two of the at least three configured frequency bands.

[0006] In some embodiments, transmitting an uplink signal in one or two of the at least three configured frequency bands includes: transmitting an uplink signal in any one of the at least three configured frequency bands, or transmitting an uplink signal in parallel in the first frequency band and the second frequency band among the at least three configured frequency bands.

[0007] In some embodiments, the first frequency band and the second frequency band are any two of the at least three configured frequency bands, or are some two of the at least three configured frequency bands.

[0008] In some embodiments, the terminal has the ability to transmit a single uplink data stream or a double uplink data stream in each of the at least three configured frequency bands, and has the ability to transmit a double uplink data stream in at least one of the at least three configured frequency bands.

[0009] In some embodiments, at different times, if the terminal transmits uplink signals in different frequency bands, a transmitter frequency band switch is performed.

[0010] In some embodiments, at different times, if the number of transmitters on at least one uplink frequency band is different, a transmitter frequency band switch is performed.

[0011] In some embodiments, when the terminal performs a transmitter frequency band switching between a first frequency band and a second frequency band among at least three configured frequency bands, the terminal satisfies at least one of a first condition and a second condition, where the first condition includes: the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band; the second condition includes: the terminal supports frequency band switching based on supplementary uplink combination between the first frequency band and the second frequency band.

[0012] In some embodiments, when the terminal performs a transmitter frequency band switching while transmitting uplink signals in parallel between a first frequency band and a second frequency band among at least three configured frequency bands, the terminal satisfies a third condition, where the third condition includes that the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band, and supports radio frequency capabilities that meet the requirements of frequency band uplink carrier aggregation between the first frequency band and the second frequency band.

[0013] In some embodiments, the terminal does not need to support radio frequency capabilities for simultaneous uplink concurrency among at least three configured frequency bands.

[0014] In some embodiments, when the terminal is configured with at least three frequency bands, the switching time for the terminal to perform a transmitter frequency band switching between the first frequency band and the second frequency band is the same as the switching time for the terminal to perform a transmitter frequency band switching between the first frequency band and the second frequency band when the terminal is configured with two frequency bands.

[0015] In some embodiments, the switching time for the terminal to perform a transmitter frequency band switching between any two of at least three configured frequency bands is the same, or different.

[0016] In some embodiments, when the terminal has the ability to send uplink dual data streams in both the first frequency band and the second frequency band, the switching time for the terminal to perform a transmitter frequency band switching between the first frequency band and the second frequency band reuses the switching time for the terminal to perform a transmitter frequency band switching for uplink two-transmit - two-receive between the first frequency band and the second frequency band when the terminal is configured with two frequency bands.

[0017] In some embodiments, when the terminal has the ability to send a single uplink data stream in the first frequency band and the ability to send uplink dual data streams in the second frequency band, the switching time for the terminal to perform a transmitter frequency band switching between the first frequency band and the second frequency band reuses the switching time for the terminal to perform a transmitter frequency band switching for uplink one-transmit - two-receive between the first frequency band and the second frequency band when the terminal is configured with two frequency bands.

[0018] In some embodiments, when the terminal has the ability to send a single uplink data stream in both the first frequency band and the second frequency band, the switching time for the terminal to perform a transmitter frequency band switching between the first frequency band and the second frequency band reuses the switching time for the terminal to perform a transmitter frequency band switching for uplink one-transmit - one-receive between the first frequency band and the second frequency band when the terminal is configured with two frequency bands.

[0019] In some embodiments, the terminal is configured in at least three frequency bands, and the switching time for switching the transmitter frequency band between any two frequency bands is greater than or equal to the switching time when the terminal is configured in two frequency bands and performs transmitter frequency band switching between the two frequency bands.

[0020] In some embodiments, the terminal is configured in at least three frequency bands, and the switching times for switching the transmitter frequency band between any two frequency bands are the same or different.

[0021] In some embodiments, the terminal is configured in at least three frequency bands, the switching times for switching the transmitter frequency band between any two frequency bands are the same, and the switching time for switching the transmitter frequency band between any two frequency bands is the maximum value among the multiple switching times for switching the transmitter frequency band between any two frequency bands when the terminal is configured with any two frequency bands.

[0022] In some embodiments, an uplink interruption is performed during the transmitter frequency band switching time.

[0023] In some embodiments, the first transmitter of the terminal switches between the first frequency band and the second frequency band among at least three configured frequency bands, and the second transmitter is in the third frequency band among at least three frequency bands and does not switch. Then, during the switching time between the first frequency band and the second frequency band, the terminal can send an uplink signal in the third frequency band.

[0024] In some embodiments, the first transmitter of the terminal switches between the first frequency band and the second frequency band among at least three configured frequency bands, and the second transmitter is in the third frequency band among at least three frequency bands and does not switch. Then, during the switching time between the first frequency band and the second frequency band, the terminal cannot send an uplink signal in the third frequency band.

[0025] According to another aspect of the present disclosure, a terminal is further provided, wherein the terminal is configured in at least three frequency bands, including: a signal sending unit, configured to send an uplink signal in one or two of the at least three configured frequency bands.

[0040] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] To make the objectives, technical solutions, and advantages of the present disclosure more clear and understandable, the following further describes the present disclosure in detail with reference to specific embodiments and the accompanying drawings.

[0042] Figure 1 It is a schematic flowchart of some embodiments of the uplink signal transmission method of the present disclosure.

[0043] In step 110, the terminal is configured with at least three frequency bands.

[0044] For the situation where there are multiple low frequencies below 1 GHz (such as 700 MHz, 800 MHz, and 900 MHz), medium frequencies around 2 GHz (1.8 GHz, 2.1 GHz), and high frequencies of 3.5 GHz and above in the access network at the same time, the terminal is configured with three or more frequency bands. For example, the terminal is configured with three uplink frequency bands of 700 MHz, 1.8 GHz, and 3.5 GHz, and each frequency band has one or more carrier units.

[0045] In step 120, the terminal transmits uplink signals on one or two of the at least three configured frequency bands.

[0046] In some embodiments, the terminal transmits uplink signals on any one of the at least three configured frequency bands, or transmits uplink signals in parallel on the first frequency band and the second frequency band among the at least three configured frequency bands. The first frequency band and the second frequency band are any two of the at least three configured frequency bands, or are some two of the at least three configured frequency bands.

[0047] For example, the terminal is configured with frequency bands A, B, and C, and can transmit uplink signals alone on any one of frequency bands A, B, and C.

[0048] For another example, the terminal can transmit uplink signals concurrently on frequency bands A + B, B + C, and A + C. Which frequency bands the terminal specifically transmits on is scheduled by the base station, and the sum of the transmitters concurrently operating on each frequency band <= 2.

[0049] For another example, the terminal can transmit uplink signals concurrently on frequency bands A + B and A + C, but cannot transmit uplink signals concurrently on frequency band B + C.

[0050] In some embodiments, the uplink transmission capability of the terminal on each frequency band includes: the terminal has uplink single data stream transmission capability or uplink dual data stream transmission capability on each of the at least three configured frequency bands, and has uplink dual data stream transmission capability on at least one of the at least three configured frequency bands.

[0051] For example, the terminal has a maximum single-transmission capability in the A band, and a maximum dual-transmission capability in the B and C bands; or, the A and B bands have a maximum single-transmission capability, and the C band has a maximum dual-transmission capability.

[0052] In the above embodiments, the terminal is provided with two sets of transmitters and configured in three or more bands. The number of bands for simultaneously transmitting signals is one or two, realizing the dynamic utilization of multiple bands and improving the utilization rate of uplink spectrum resources.

[0053] In some other embodiments of the present disclosure, at different times, if the terminal transmits an uplink signal in different bands, the transmitter band is switched. Or, at different times, if the number of transmitters of the terminal is different on at least one uplink band, the transmitter band is switched.

[0054] For example, at a previous moment, the terminal transmits an uplink signal in the A band, and at a subsequent moment, it transmits an uplink signal in the B band. And if both the A band and the B band are for uplink dual-data-stream transmission, both transmitters perform band switching.

[0055] For another example, at a previous moment, the first transmitter transmits an uplink signal in the A band, and the second transmitter transmits an uplink signal in the B band. At a subsequent moment, both the first transmitter and the second transmitter transmit an uplink signal in the B band, then the first transmitter performs band switching.

[0056] For another example, at a previous moment, the first transmitter transmits an uplink signal in the A band, and the second transmitter transmits an uplink signal in the C band. At a subsequent moment, both the first transmitter and the second transmitter transmit an uplink signal in the B band, then both transmitters perform band switching.

[0057] For another example, at a previous moment, the first transmitter transmits an uplink signal. At a subsequent moment, the first transmitter and the second transmitter transmit uplink signals concurrently. The first transmitter is in the A band at both moments, and the second transmitter is in the A band at the previous moment and in the B band at the subsequent moment, then only the second transmitter performs band switching.

[0058] For another example, at a previous moment, the first transmitter transmits an uplink signal in the A band and the second transmitter is in the A band but does not transmit an uplink signal. At a subsequent moment, both the first transmitter and the second transmitter transmit an uplink signal in the B band, then both transmitters perform band switching.

[0059] In some embodiments, when the terminal performs a transmitter frequency band switching between a first frequency band and a second frequency band, the terminal satisfies at least one of a first condition and a second condition, where the first condition is that the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band; the second condition is that the terminal supports frequency band switching based on supplementary uplink combination between the first frequency band and the second frequency band. That is, the terminal supports being configured on these two frequency bands and performing uplink transmitter frequency band switching between these two frequency bands.

[0060] In some embodiments, when the terminal performs transmitter frequency band switching while transmitting uplink signals in parallel on the first frequency band and the second frequency band, the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band, and supports satisfying the radio frequency capabilities based on frequency band uplink carrier aggregation between the first frequency band and the second frequency band.

[0061] In some embodiments, the terminal does not need to support the radio frequency capabilities of performing uplink concurrency simultaneously on multiple configured frequency bands.

[0062] In the above embodiments, if the uplink transmission frequency bands at different times are different, or the number of transmission antennas of at least one uplink transmission frequency band is different, then dynamic switching of the terminal transmitter is required, and the transmitter switching requirements for the corresponding fallback frequency band pairs are defined.

[0063] In some other embodiments of the present disclosure, when the terminal is configured on at least three frequency bands, the switching time for performing transmitter frequency band switching between the first frequency band and the second frequency band is the same as the switching time for performing transmitter frequency band switching between the first frequency band and the second frequency band when the terminal is configured on two frequency bands.

[0064] For example, if in the related art, the terminal is configured on frequency band A and frequency band B, and the switching time between frequency band A and frequency band B is t1. In this embodiment, the terminal is configured on three uplink frequency bands, namely frequency band A, frequency band B, and frequency band C, and the switching time between frequency band A and frequency band B is also t1. If in the related art, the terminal is configured on frequency band A and frequency band C, and the switching time between frequency band A and frequency band C is t2. In this embodiment, the terminal is configured on three uplink frequency bands, namely frequency band A, frequency band B, and frequency band C, and the switching time between frequency band A and frequency band C is also t2.

[0065] In some embodiments, the switching time for the terminal to perform transmitter frequency band switching between any two frequency bands is the same, or different. That is, the switching times for different frequency band pairs are the same or different. For example, the switching time of the transmitter between frequency band A and frequency band B is t1, and the switching time of the transmitter between frequency band B and frequency band C is also t1; or, the switching time of the transmitter between frequency band A and frequency band B is t1, and the switching time of the transmitter between frequency band B and frequency band C is t2.

[0066] In some embodiments, in the N-band switching mode, if both of two bands to be switched support up to two transmitters in the uplink, then the "switching time when the terminal is configured on these two bands and performs a two-transmitter - two-transmitter switch in the uplink on the two bands" is reused. If on two bands to be switched, one band supports up to one transmitter in the uplink and the other band supports up to two transmitters in the uplink, then the "switching time when the terminal is configured on these two bands and performs a one-transmitter - two-transmitter switch in the uplink on the two bands" is reused. If on each of two bands of a certain band, both support up to one transmitter in the uplink, then the "switching time when the terminal is configured on these two bands and performs a one-transmitter - one-transmitter switch in the uplink on the two bands" is reused.

[0067] In the above embodiments, by determining the transmitter switching time, within the transmitter band switching time, the base station does not perform uplink scheduling, and the terminal performs an uplink interruption, that is, the terminal does not send uplink signals. For example, when one or two transmitters of the terminal switch between two of these bands, then within the switching time, the terminal cannot send uplink signals on these two uplink bands.

[0068] In some other embodiments of the present disclosure, the terminal is configured on at least three bands, and the switching time for any two bands to perform a transmitter band switch is greater than or equal to the switching time when the terminal is configured on two bands and performs a transmitter band switch on the two bands.

[0069] In some embodiments, the switching time for the terminal to perform a transmitter band switch between any two bands is the same or different. For example, the switching time between the A band and the B band, and the switching time between the A band and the C band of the terminal are both t1. Or, the switching time between the A band and the B band of the terminal is t1, and the switching time between the A band and the C band is t2.

[0070] In some embodiments, the terminal is configured on at least three bands, the switching time for performing a transmitter band switch between any two bands is the same, and moreover, the switching time for performing a transmitter band switch between any two bands is the maximum value among multiple switching times when the terminal is configured on any two bands and performs a transmitter band switch between any two bands.

[0071] For example, in the related art, if the terminal is configured on the A band and the B band, the switching time between the A band and the B band is t1, or if the terminal is configured on the A band and the C band, the switching time between the A band and the C band is t2, where t2 > t1. For the terminal of the present disclosure configured on the A band, the B band, and the C band, the switching time between the A band and the C band, and the switching time between the A band and the B band are both t2.

[0072] In the above embodiments, by determining the transmitter switching time, during the transmitter frequency band switching time, the base station does not perform uplink scheduling, and the terminal performs an uplink interruption. For example, when one or two transmitters of the terminal switch between two frequency bands, during the switching time, the terminal cannot send uplink signals on these two uplink frequency bands.

[0073] In some embodiments, if one transmitter of the terminal switches between two frequency bands and the second transmitter is in a third frequency band without switching, during the switching time of the first two frequency bands, the terminal can or cannot send uplink signals on the third uplink frequency band.

[0074] In any two frequency bands in each of the above embodiments of the transmitter switching time, it refers to any two frequency bands capable of performing uplink transmitter frequency band switching.

[0075] This disclosure focuses on the actual deployment scenarios of 5G-Advanced networks. Combining the capabilities of commercial handheld terminals and the current status of 3GPP standards, this disclosure can efficiently and dynamically utilize uplink spectrum resources, improving the utilization rate of spectrum resources.

[0076] Figure 2 It is a schematic structural diagram of some embodiments of the terminal of this disclosure. The terminal is configured in at least three frequency bands and includes a sending unit 210 for sending uplink signals on one or two of the configured at least three frequency bands.

[0077] In some embodiments, the terminal sends uplink signals on any one of the configured at least three frequency bands, or sends uplink signals in parallel on the first and second frequency bands among the configured at least three frequency bands. The first and second frequency bands are any two of the configured at least three frequency bands, or are some two of the configured at least three frequency bands.

[0078] In some embodiments, the uplink sending capabilities of the terminal on each frequency band include: the terminal has uplink single data stream sending capabilities or uplink dual data stream sending capabilities on each of the configured at least three frequency bands, and has uplink dual data stream sending capabilities on at least one of the configured at least three frequency bands.

[0079] In the above embodiments, the terminal is configured in three or more frequency bands and sends uplink signals on one or two frequency bands, realizing the dynamic utilization of multiple frequency bands and improving the utilization rate of uplink spectrum resources.

[0080] In some other embodiments of this disclosure, the terminal further includes a switching unit 220 for, at different times, if the terminal sends uplink signals on different frequency bands, performing transmitter frequency band switching; or, at different times, if the number of transmitters of the terminal on at least one uplink frequency band is different, performing transmitter frequency band switching.

[0081] In some embodiments, when the terminal performs a transmitter frequency band switching between a first frequency band and a second frequency band, the terminal satisfies at least one of a first condition and a second condition, where the first condition is that the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band; and the second condition is that the terminal supports frequency band switching based on supplementary uplink combination between the first frequency band and the second frequency band.

[0082] In some embodiments, when the terminal performs transmitter frequency band switching while transmitting uplink signals in parallel on the first frequency band and the second frequency band, the terminal supports frequency band switching based on carrier aggregation between the first frequency band and the second frequency band, and supports the radio frequency capabilities that satisfy carrier aggregation of uplink carriers based on the frequency band between the first frequency band and the second frequency band.

[0083] In some embodiments, the terminal does not need to support the radio frequency capabilities for simultaneous uplink concurrency on multiple configured frequency bands.

[0084] In the above embodiments, if the uplink transmission frequency bands at different times are different, or the number of transmission antennas for at least one uplink transmission frequency band is different, then dynamic switching of the terminal transmitter is required, and the transmitter switching requirements for the corresponding fallback frequency band pairs are defined.

[0085] In some other embodiments of the present disclosure, when the terminal is configured with at least three frequency bands, the switching time for performing transmitter frequency band switching between the first frequency band and the second frequency band is the same as the switching time for performing transmitter frequency band switching between the first frequency band and the second frequency band when the terminal is configured with two frequency bands.

[0086] In some embodiments, the switching time for the terminal to perform transmitter frequency band switching between any two frequency bands is the same, or different.

[0087] In some embodiments, in the N-band switching mode, if on two frequency bands undergoing switching, both support a maximum of two uplink transmissions, then reuse the "switching time for the terminal configured with these two frequency bands and performing two-transmission transmitter switching for two uplink transmissions on the two frequency bands". If on two frequency bands undergoing switching, one frequency band supports a maximum of one uplink transmission and the other frequency band supports a maximum of two uplink transmissions, then reuse the "switching time for the terminal configured with these two frequency bands and performing one-two transmission transmitter switching for uplink transmissions on the two frequency bands". If on each of the two frequency bands of a certain frequency band pair, both support a maximum of one uplink transmission, then reuse the "switching time for the terminal configured with these two frequency bands and performing one-one transmission transmitter switching for uplink transmissions on the two frequency bands".

[0088] In the above embodiments, by determining the transmitter switching time, within the transmitter frequency band switching time, the base station no longer performs uplink scheduling, and the terminal executes an uplink interruption. For example, when one or two transmitters of the terminal switch between two frequency bands, within the switching time, the terminal cannot send uplink signals on these two uplink frequency bands.

[0089] In some other embodiments of the present disclosure, the terminal is configured with at least three frequency bands, and the switching time for any two frequency bands to perform transmitter frequency band switching is greater than or equal to the switching time when the terminal is configured with two frequency bands and performs transmitter frequency band switching between the two frequency bands.

[0090] In some embodiments, the switching time for the terminal to perform transmitter frequency band switching between any two frequency bands is the same or different.

[0091] In some embodiments, when the terminal is configured with at least three frequency bands, the switching time for performing transmitter frequency band switching between any two frequency bands is the same, and the switching time for performing transmitter frequency band switching between any two frequency bands is the maximum value among the multiple switching times when the terminal is configured with any two frequency bands and performs transmitter frequency band switching between any two frequency bands.

[0092] In the above embodiments, by determining the transmitter switching time, within the transmitter frequency band switching time, the base station no longer performs uplink scheduling, and the terminal executes an uplink interruption. For example, when one or two transmitters of the terminal switch between two frequency bands, within the switching time, the sending unit 210 cannot send uplink signals on these two uplink frequency bands.

[0093] In some embodiments, if one transmitter of the terminal switches between two frequency bands and the second transmitter is in the third frequency band and does not switch, within the switching time of the first two frequency bands, the sending unit 210 can or cannot send uplink signals on the third uplink frequency band.
