Description

Uplink transmission method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 2, 2023, with application number 202311458713.8 and invention name “Uplink Transmission Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and more specifically, to an uplink transmission method and a communication device. Background Art

[0003] In cellular network-based uplink positioning, a terminal device can send a sounding reference signal (SRS) to the network device, allowing the network device to determine the terminal device's location using positioning technology. However, the measurement accuracy of positioning technology is affected by the bandwidth occupied by the SRS. The larger the bandwidth occupied by the SRS, the higher the measurement accuracy of the positioning technology, and the more accurate the terminal device's location is.

[0004] When the bandwidth supported by a terminal device for a single SRS transmission is small, the terminal device can transmit the SRS via frequency hopping. The network device receives and processes the SRS transmitted by the terminal device via frequency hopping, thereby improving the measurement accuracy of positioning technology. For example, a terminal device can transmit an SRS with a bandwidth of 20 megahertz (MHz) in five frequency hopping sub-bands. After receiving and processing the SRS in the five frequency hopping sub-bands, the network device can obtain measurement results equivalent to or similar to those corresponding to an SRS with a bandwidth of 100 MHz.

[0005] Generally speaking, the terminal device sends SRS according to the frequency hopping pattern configured by the network device. Due to the flexibility of the frequency hopping pattern, the network device can schedule or configure the terminal device to send an uplink signal or an uplink channel between two consecutive frequency hopping sub-bands in the time domain. However, the time required for the terminal device to switch from the resource position for sending the previous hop SRS to the resource position for sending the uplink signal or uplink channel, and then from the resource position for sending the uplink signal or uplink channel to the resource position for sending the next hop SRS may be longer than the time domain interval between the two frequency hops, causing the time domain resources for sending the uplink signal or uplink channel to conflict with the time domain resources for sending the next hop SRS. Alternatively, the time domain resource position for the uplink signal or uplink channel that the network device needs to schedule just overlaps with the time domain resources for the terminal device to send a certain hop SRS.

[0006] Therefore, when the resources for frequency hopping SRS transmission of the terminal device conflict with the time domain resources for transmitting uplink signals or uplink channels, how to perform uplink transmission becomes an urgent problem to be solved.

[0007] Summary of the Invention

[0008] The present application provides an uplink transmission method and a communication device, which can resolve the conflict when the time domain resources required for sending SRS in a frequency hopping manner conflict with the time domain resources required for sending other uplink information.

[0009] In a first aspect, an uplink transmission method is provided, which can be executed by a terminal device or by a component of the terminal device (such as a chip or a chip system, etc.), and this application does not limit this. The method includes: when it is determined at a first moment or before the first moment that a first time domain unit and a second time domain unit overlap, sending first uplink information; wherein the first moment is before the second moment and is separated from the second moment by a first time length, the second moment corresponds to the starting moment of the first time domain unit, the first time domain unit is the time domain resource occupied by the nth frequency hop in m frequency hops, the m frequency hops are used to transmit SRS, the second time domain unit is the time domain resource occupied by the first uplink information, the first time length is associated with at least one of the SRS, the first uplink information or a physical downlink control channel (PDCCH), and the PDCCH is used to schedule the first uplink information.

[0010] In the second aspect, an uplink transmission method is provided, which can be executed by a terminal device or by a component of the terminal device (such as a chip or a chip system, etc.), and this application does not limit this. The method includes: when it is determined at a first moment or before the first moment that the first time domain unit and the second time domain unit overlap, sending the first uplink information; wherein the first moment is after the third moment and is separated from the third moment by a first time length, the third moment corresponds to the end moment of the PDCCH, the PDCCH is used to schedule the first uplink information, the first time domain unit is the time domain resource occupied by the nth frequency hop in the m frequency hops, the m frequency hops are used to transmit the SRS, the second time domain unit is the time domain resource occupied by the first uplink information, and the first time length is associated with at least one of the SRS, the first uplink information or the PDCCH.

[0011] In the above technical solution, the first moment is determined according to the starting moment of each hop SRS sent by the terminal device or according to the received PDCCH. Before the first moment, if the terminal device can determine that the first uplink information and the time domain resources for frequency hopping SRS transmission conflict, then the first uplink information is sent instead of SRS, which helps to solve the problem of conflict between SRS resources and other uplink information resources during the frequency hopping SRS transmission process.

[0012] The second moment corresponds to the start moment of the first time domain unit and may include any of the following: the second moment is the start moment of the first time domain unit; the second moment is a moment before the start moment of the first time domain unit, and the second moment and the start moment of the first time domain unit are separated by a first preset duration; or the second moment is a moment after the start moment of the first time domain unit, and the second moment and the start moment of the first time domain unit are separated by a first preset duration. Exemplarily, the first preset duration may be associated with the capabilities of the terminal device, for example, the first preset duration may be 0.01 milliseconds (ms), or 0.05 ms, or other durations.

[0013] The third moment corresponds to the end moment of the PDCCH and may include any of the following: the third moment is the end moment of the terminal device receiving the PDCCH; the third moment is a moment before the end moment of the PDCCH, and the third moment and the end moment of the PDCCH are separated by a second preset duration; or the third moment is a moment after the end moment of the PDCCH, and the third moment and the end moment of the PDCCH are separated by a second preset duration. Exemplarily, the second preset duration may be associated with the capability of the terminal device, for example, the second preset duration may be 0.01 milliseconds (ms), or 0.05 ms, or other durations.

[0014] It should be noted that the SRS involved in the present application may be an SRS for positioning sent in a frequency hopping manner, and each of the m frequency hops may occupy one symbol or multiple symbols.

[0015] In some implementations, m and n are both positive integers, and m is greater than or equal to n.

[0016] In some implementations, before determining that the first time domain unit and the second time domain unit overlap, the method further includes: receiving a PDCCH, and determining, according to the PDCCH, a second time-frequency unit required for sending the first uplink information.

[0017] In some implementations, before determining that the first time domain unit and the second time domain unit overlap, the method further includes: receiving resource configuration information for sending the first uplink information, and determining the second time-frequency unit required to send the first uplink information based on the resource configuration information.

[0018] In some implementations, when it is not determined at or before the first moment that the first time domain unit and the second time domain unit overlap, the SRS is sent and the first uplink information is not sent.

[0019] In some implementations, when it is determined at or before the first time instant that the first time domain unit and the second time domain unit overlap, the SRS is not sent in the first time domain unit.

[0020] In combination with the first aspect or the second aspect, in certain implementations of the first aspect or the second aspect, sending the first uplink information includes: sending the first uplink information in the second time domain unit; the method also includes: sending the SRS in the third time domain unit, the third time domain unit being the part of the first time domain unit excluding the overlapping part with the second time domain unit.

[0021] In the above technical solution, when the time domain resources of the first uplink information conflict with the time domain resources required for frequency hopping to send SRS, after determining to send the first uplink information, the part of the SRS that conflicts with the first uplink information is discarded, and the remaining part of the SRS that does not conflict with the first uplink information is sent. While resolving the time domain resource conflict, it also helps to ensure the accuracy of positioning through the first type of SRS.

[0022] In combination with the first aspect or the second aspect, in certain implementations of the first aspect or the second aspect, it includes: the first duration is associated with the first subcarrier spacing, and the first subcarrier spacing is associated with at least one of SRS, first uplink information or PDCCH.

[0024] In the above technical solution, selecting the smallest subcarrier spacing helps to maximize the first duration, so that the terminal device has enough time to prepare for sending the first uplink information.

[0027] Exemplarily, the first duration includes a first sub-duration and a second sub-duration, the first sub-duration is determined according to the first subcarrier spacing, and the second sub-duration is determined according to the duration required for BWP switching.

[0028] In the above technical solution, when determining the first duration, the time required for the terminal device to perform BWP switching is taken into consideration, which can ensure that the terminal device has sufficient time to perform BWP switching and improve the success rate of sending the first uplink information.

[0083] It should be understood that FIG1 is merely a simplified schematic diagram for ease of understanding, and the wireless communication system 100 may further include other network devices or other terminal devices, which are not shown in FIG1 .

[0084] Positioning is a critical function in mobile communication systems, requiring the system to provide real-time user location information. 5G communication systems place high-precision positioning requirements, requiring outdoor positioning errors to be less than 10 meters and indoor positioning errors to be less than 1 meter. Positioning technologies can include uplink positioning, downlink positioning, and both uplink and downlink positioning. In uplink positioning, network equipment measures the SRS signal transmitted by the terminal device. In actual positioning scenarios, network equipment can include a serving base station and also neighboring base stations. A serving base station is a base station located in the cell where the terminal device to be located is located. The serving base station can provide communication connection services for the terminal device to be located. There can be at least two neighboring base stations. The neighboring base stations can be the base station of the cell where the terminal device to be located is located, or they can be base stations of other cells. Alternatively, some neighboring base stations can be base stations of the cell where the terminal device to be located is located and some can be base stations of other cells.

[0085] Figure 2 shows a schematic diagram of a positioning scenario. As shown in Figure 2, the serving base station can send configuration information to the terminal device. The configuration information may include SRS resource information, and the SRS resource information indicates the time-frequency resource position occupied by an SRS resource. The time domain types of SRS resource configuration are periodic, semi-continuous and non-periodic. The configuration information of the periodic SRS resource includes a period (such as 2ms, 5ms, 10ms, etc.) and a bias parameter. After the serving base station configures the SRS resource for the terminal device, the terminal device will send the SRS on the determined SRS resource according to the configuration information within the time slot of a specific period. The configuration information of the non-periodic SRS resource does not include a period, but only includes a time domain offset K of the downlink control information (DCI) that triggers the SRS. When the terminal device receives the DCI signaling at the Mth moment and the signaling indicates that the SRS is triggered, the SRS will be sent on the corresponding SRS resource at the M+Kth moment, where K and M are positive integers. SRS can support transmission in a frequency hopping manner, and specific frequency hopping characteristics can be determined by parameters in both the time domain and the frequency domain.

[0086] In a specific implementation, when it is necessary to send SRS in a frequency hopping manner, the SRS resource information can indicate the following: the position of the starting physical resource block (PRB) in the frequency domain of the resources required for the first frequency hopping transmission of SRS in the time domain, the bandwidth occupied by each frequency hopping transmission of SRS, the number of overlapping frequency domain resources required for two consecutive SRS hops (such as the number of overlapping PRBs), the starting time slot offset and starting symbol corresponding to the time domain resources occupied by each frequency hopping transmission of SRS, and the number of consecutive symbols required for each frequency hopping transmission of SRS. Based on the above SRS resource information, the terminal device can determine a unique frequency hopping pattern, that is, the time and frequency resources required for each hop when frequency hopping to send SRS. Whether it is periodic, semi-continuous, or non-periodic SRS, it can be configured as a frequency hopping pattern. The frequency hopping corresponding to each frequency hopping pattern can be completed in one time slot or multiple time slots. Furthermore, the terminal device can send SRS for positioning (hereinafter referred to as positioning SRS) according to the frequency hopping pattern. For example, the terminal device may send a positioning SRS to the serving base station, and the terminal device may also send a positioning SRS to the neighboring base station 1 and / or the neighboring base station 2. After receiving the positioning SRS, the serving base station and / or the neighboring base station measure the arrival time of the SRS, and then determine the position of the terminal device to be located based on the time of arrival (TOA) positioning technology or the angle of arrival (UL-AOA) positioning technology.

[0087] As described above, when the network device configures or schedules the terminal to send a positioning SRS in a frequency hopping manner, the network device may still schedule or configure the terminal device to send an uplink signal or an uplink channel, causing the resources for the terminal device to send the positioning SRS and the resources for sending the uplink signal or the uplink channel to overlap in the time domain, or the time required for the terminal device to switch from the resource position for sending the previous hop SRS to the resource position for sending other uplink signals or channels and send them, and then switch to the resource position for the next hop SRS, exceeds the configured time interval between two consecutive hop SRSs, resulting in a time domain resource conflict.

[0088] Figure 3 shows an exemplary flow chart of the uplink transmission method provided in an embodiment of the present application. The method 300 shown in Figure 3 can resolve the conflict between the time domain resources required for sending SRS in a frequency hopping manner and the time domain resources required for the uplink channel or signal. For the convenience of description, the following example uses the execution subject of method 300 as an example of a terminal device. It can be understood that the execution subject of method 300 can also be a component of the terminal device, such as a chip or a chip system or a circuit, which is not limited to this. The steps described below as being performed by a single execution subject can also be divided into steps performed by multiple execution subjects, and these execution subjects can be logically and / or physically separated. The method 300 shown in Figure 3 may include the following steps.

[0089] S301, at a first moment or before the first moment, determine that there is an overlap between a first time domain unit and a second time domain unit, wherein the first moment is before the second moment and is separated from the second moment by a first time length, the second moment corresponds to the starting moment of the first time domain unit, the first time domain unit is the time domain resource occupied by the nth frequency hop in m frequency hops, the m frequency hops are used to transmit SRS, the second time domain unit is the time domain resource occupied by the first uplink information, the first time length is associated with at least one of the SRS, the first uplink information or PDCCH, and the PDCCH is used to schedule the first uplink information.

[0090] Exemplarily, the SRS may include the aforementioned positioning SRS. Hereinafter, the SRS transmitted via frequency hopping is referred to as a first-type SRS. The time-domain transmission method of the first-type SRS may be periodic, semi-continuous, or aperiodic, which is not specifically limited in this application. Both m and n are positive integers, and m is greater than or equal to n.

[0091] In some implementations, before executing S301, the method further includes: the terminal device receives first-category SRS resource configuration information, and determines, based on the first-category SRS resource configuration information, a first time domain unit and a second time corresponding to the nth frequency hop for transmitting the first-category SRS. Exemplarily, the content indicated by the first-category SRS resource configuration information can refer to the description in the above-mentioned embodiment and is not further described here. The first-category SRS resource configuration information may include the SRS resource information in the above-mentioned embodiment.

[0092] In some implementations, before executing S301, the method further includes: the terminal device receives a PDCCH, and determines, according to downlink control information (DCI) carried by the PDCCH, a second time domain unit corresponding to sending the first uplink information.

[0093] In some implementations, before executing S301, the method further includes: the terminal device receives configuration information, the configuration information includes time-frequency resources used to send the first uplink information, and determines the second time domain unit corresponding to sending the first uplink information based on the configuration information.

[0094] S302: Send first uplink information.

[0095] S301 and S302 are described in detail below in conjunction with Figure 4. In Figure 4, taking time domain unit 1 as the first time domain unit and time domain unit 2 as the second time domain unit as an example, moment t1 can be understood as the second moment determined according to the first type of SRS resource configuration information, moment t2 can be understood as the first moment, and the duration between moment t1 and moment t2 is the first duration, which may include N symbols. Exemplarily, the first duration and / or N symbols can be determined based on the capabilities of the terminal device. Specifically, as shown in Figure 4, at moment t2 or before moment t2, it is determined that time domain unit 1 and time domain unit 2 overlap, then the first uplink information is sent through time domain unit 2, and the first type of SRS is not sent.

[0096] In some implementations, as shown in FIG5 , at or before time t2 , if the terminal device does not determine that time domain unit 1 and time domain unit 2 overlap, the first type of SRS is sent through time domain unit 1 without sending the first uplink information.

[0097] In some implementations, the terminal device determines the first moment based on the first duration and the second moment, wherein the first duration is associated with at least one of the first type of SRS, the first uplink information, or the PDCCH, including: the first duration is associated with the first subcarrier spacing, and the first subcarrier spacing is associated with at least one of the first type of SRS, the first uplink information, or the physical downlink control channel PDCCH. Alternatively, the first duration is determined by the terminal device capability. The terminal device capability is associated with at least one of the first type of SRS, the first uplink information, or the PDCCH, for example, the terminal device capability is associated with the first subcarrier spacing, and the first subcarrier spacing is associated with at least one of the first type of SRS, the first uplink information, or the physical downlink control channel PDCCH.

[0098] Among them, the first subcarrier spacing is associated with at least one of the first type of SRS, the first uplink information or the physical downlink control channel PDCCH, which may include: the first subcarrier spacing is the subcarrier spacing for sending the first type of SRS, or the subcarrier spacing for sending the first uplink information, or the subcarrier spacing for receiving PDCCH; or, the first subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacing for sending the first type of SRS, the subcarrier spacing for sending the first uplink information, and the subcarrier spacing for receiving PDCCH; or, the first subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacing for sending the first uplink information and the subcarrier spacing for sending the first type of SRS; or, the first subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacing for sending the first uplink information and the subcarrier spacing for receiving PDCCH; or, the first subcarrier spacing is the minimum subcarrier spacing among the subcarrier spacing for sending the first type of SRS and the subcarrier spacing for receiving PDCCH.

[0099] In some implementations, the first duration and / or the value of N are related to the capabilities of the terminal device. For example, if the capability of the terminal device is processing capability 1, the relationship between the first subcarrier spacing and the value of N can be as shown in Table 1; if the capability of the terminal device is processing capability 2, the relationship between the first subcarrier spacing and the value of N can be as shown in Table 2. Processing capability 1 and processing capability 2 are as defined in the communication protocol 3GPP TS 38.214 and are not further described here. In Tables 1 and 2, μ represents the subcarrier spacing type, and Δf represents the subcarrier spacing.

[0100] Table 1

[0101] Table 2

[0102] Among them, frequency range 1 refers to the low frequency band, that is, the frequency range of 410MHz to 7125MHz.

[0103] For example, if the terminal device has a processing capability of 1 and the first subcarrier spacing determined is 120 kHz, the first duration may be the duration corresponding to 36 symbols when the subcarrier spacing is 120 kHz, that is, 0.125 / 14×36≈0.32 ms. For another example, if the terminal device has a processing capability of 2 and the first subcarrier spacing determined is 30 kHz, the first duration may be the duration corresponding to 5.5 symbols when the subcarrier spacing is 30 kHz, that is, 0.5 / 14×5.5≈0.20 ms.

[0104] In some implementations, the first duration may be determined based on a second subcarrier spacing, where the value of the second subcarrier spacing is less than or equal to a preset threshold. For example, the preset threshold may be 30 kHz, or 60 kHz. Alternatively, the preset threshold may be related to the capabilities of the terminal device. For example, the preset threshold corresponding to processing capability 1 may be 120 kHz, and the preset threshold corresponding to processing capability 2 may be 60 kHz.

[0105] It should be noted that, in a specific implementation, the first subcarrier spacing or the second subcarrier spacing can be as small as possible, so that the determined first duration is as large as possible.

[0106] In some implementations, the first uplink information includes a first uplink channel and / or a first uplink signal, the first uplink channel includes a PUCCH or a PUSCH, and the first uplink signal includes a second-type SRS. The second-type SRS can be understood as any SRS other than an SRS transmitted via frequency hopping, such as an SRS for beam management, an SRS for codebook-based or non-codebook downlink transmission, an SRS for antenna switching, or an SRS for positioning that is not transmitted via frequency hopping.

[0107] The uplink transmission method provided in the embodiment of the present application determines the first moment according to the starting moment of the terminal device sending each hop SRS. Before the first moment, if the terminal device can determine that the time domain resources of the first uplink information and the first type of SRS conflict, then the first uplink information is sent instead of the first type of SRS, which helps to solve the problem of conflict between SRS resources and other uplink information resources during the frequency hopping transmission of SRS.

[0108] Figure 6 shows an exemplary flow chart of the uplink transmission method provided in an embodiment of the present application. The method 600 shown in Figure 6 can resolve the conflict between the time domain resources required for sending SRS in a frequency hopping manner and the time domain resources required for the uplink channel or signal. For the convenience of description, the following is an exemplary explanation using the execution subject of method 600 as a terminal device. It can be understood that the execution subject of method 600 can also be a component of the terminal device, such as a chip or a chip system or a circuit, and this is not limited. The steps described below as being performed by a single execution subject can also be divided into steps performed by multiple execution subjects, and these execution subjects can be logically and / or physically separated. The method 600 shown in Figure 6 may include the following steps.

[0109] S601, determining at a first moment or before the first moment that there is an overlap between the first time domain unit and the second time domain unit, wherein the first moment is after the third moment and is separated from the third moment by a first time length, the third moment corresponds to the end moment of the physical downlink control channel PDCCH, the PDCCH is used to schedule the first uplink information, the first time domain unit is the time domain resource occupied by the nth frequency hop in m frequency hops, the m frequency hops are used to transmit SRS, the second time domain unit is the time domain resource occupied by the first uplink information, and the first time length is associated with at least one of the SRS, the first uplink information or the PDCCH.

[0110] Regarding the SRS, the method for determining the first time domain unit, and the method for determining the second time domain unit, reference may be made to the description in method 300 and will not be repeated here.

[0111] S602: Send first uplink information.

[0112] S601 and S602 are described in detail below in conjunction with Figure 7. In Figure 7, taking time domain unit 1 as the first time domain unit and time domain unit 2 as the second time domain unit as an example, time T1 can be understood as the third time determined according to the PDCCH, time T3 can be understood as the first time, the duration between time T1 and time T3 is the first duration, and the first duration may include N symbols. Time T2 is the starting time for sending the second time domain unit. Specifically, as shown in Figure 7, at or before time T3, it is determined that time domain unit 1 and time domain unit 2 overlap, then the first uplink information is sent through time domain unit 2, and the first type of SRS is not sent.

[0113] In some implementations, as shown in FIG8 , at or before time T3 , if the terminal device does not determine that time domain unit 1 and time domain unit 2 overlap, the first type of SRS is sent through time domain unit 1 without sending the first uplink information.

[0114] In some implementations, the terminal device determines the first time according to the first duration and the third time. The method for determining the first duration can be referred to the description in method 300 and will not be repeated here.

[0115] The uplink transmission method provided in the embodiment of the present application determines the first moment according to the end moment of the terminal device receiving the PDCCH. Before the first moment, if the terminal device can determine that the time domain resources of the first uplink information and the first type of SRS conflict, the first uplink information is sent instead of the first type of SRS, which helps to solve the problem of conflict between SRS resources and other uplink information resources during the frequency hopping transmission of SRS.

[0116] In an embodiment of the present application, the first moment can also be understood as the moment corresponding to the first symbol, the second moment corresponds to the start symbol of the first time domain unit, the third moment corresponds to the end symbol of the PDCCH, and there are N symbols between the start symbol of the first time domain unit and the first symbol, or, there are N symbols between the end symbol of the PDCCH and the first symbol.

[0117] It should be noted that the embodiment of the present application does not specifically limit the relationship between the start symbol of the first time domain unit and the start symbol of the second time domain unit. For example, the start symbol of the second time domain unit may be located before the start symbol of the first time domain unit, as shown in Figures 4, 5, 7, and 8; or, the start symbol of the second time domain unit may overlap with the start symbol of the first time domain unit; or, the start symbol of the second time domain unit may be located after the start symbol of the first time domain unit. In a specific implementation, no matter how the order of the start symbol of the first time domain unit and the start symbol of the second time domain unit is, as long as the terminal device can determine that the first time domain unit and the second time domain unit overlap at or before the first moment, there is enough time to prepare for sending the first uplink information.

[0118] In some implementations, the start symbol of the second time domain unit is located after the start symbol of the first time domain unit, or the end symbol of the second time domain unit is located before the end symbol of the first time domain unit. That is, the first time domain unit can be divided into two parts, one part overlapping with the second time domain unit, and the other part not overlapping with the second time domain unit. The part not overlapping with the second time domain unit is hereinafter referred to as the third time domain unit. Then, before or after executing S302 or S602, the terminal device can also send the first type SRS through the third time domain unit.

[0119] For example, as shown in Figures 9 and 10, time domain unit 3 can be regarded as an example of the third time domain unit. When it is determined that time domain unit 1 and time domain unit 2 overlap before time t2 or time T3, the first type of SRS is sent in time domain unit 3 and the first uplink information is sent in time domain unit 2.

[0120] Generally speaking, a network device can configure one or more BWPs for a terminal device. A BWP can be composed of contiguous PRBs in the frequency domain, and a BWP is a subset of the terminal device's bandwidth. The minimum granularity of a BWP in the frequency domain is one PRB, and one or more bandwidth regions can overlap in the frequency domain. In a single-carrier scenario, a terminal device can have only one active BWP at a time, and the terminal device receives data / reference signals or transmits data / reference signals on the active BWP. In some implementations, the BWP used by the terminal device to send the first uplink information, the BWP used to receive the PDCCH, and the BWP or frequency domain location used to send the first-class SRS may all be different. This requires a certain switching time for the terminal device to switch from the BWP used to receive the PDCCH to the BWP or frequency domain location used to send the first-class SRS, or it requires a certain switching time to switch from the BWP used to receive the PDCCH or the BWP or frequency domain location used to send the first-class SRS to the BWP used to send the first uplink information.

[0121] Therefore, the first duration determined in the above embodiment may include a first sub-duration and a second sub-duration, the first sub-duration being determined according to the first subcarrier spacing, and the second sub-duration being determined according to the duration required for BWP switching. That is, the duration (or number of symbols) between t2 and t1 in Figures 4, 5, and 9, or the duration (or number of symbols) between T1 and T3 in Figures 7, 8, and 10, includes the duration (or number of symbols) determined according to the first carrier spacing and the duration (or number of symbols) determined according to BWP or frequency domain position switching.

[0122] Exemplarily, the BWP switching may include any of the following: switching from the BWP or frequency domain position for sending the first type of SRS to the BWP for sending the first uplink information, switching from the BWP for receiving the PDCCH to the BWP for sending the first uplink information, and switching from the BWP for receiving the PDCCH to the BWP or frequency domain position for sending the first type of SRS. The second sub-duration is determined based on the duration required for the BWP or frequency domain position switching, which can be understood as: the second sub-duration is the duration required for the actual BWP or frequency domain position switching, or the second sub-duration can also be the longest duration required in the above three BWP or frequency domain position switching scenarios.

[0123] In the above embodiment, the duration required for BWP or frequency domain position switching is considered when determining the first duration, so that when a time domain resource conflict occurs, the terminal device can have enough time to perform BWP or frequency domain position switching.

[0124] Taking into account the time required for BWP or frequency domain position switching, combined with the scenarios shown in Figures 9 and 10, when the terminal device sends the first type of SRS in the third time domain unit and sends the first uplink information in the second time domain unit, it may only be able to send the first type of SRS within part of the symbols in the third time domain unit. For example, the third time domain unit includes 3 symbols, and switching from the BWP or frequency domain position for sending the first type of SRS to the BWP for sending the first uplink information requires a time length corresponding to 1 symbol. The terminal device sends the first type of SRS in the first 2 symbols of the third time domain unit, and then switches the BWP or frequency domain position. After the BWP or frequency domain position switch is completed, the first uplink information is sent in the second time domain unit.

[0125] The above, in combination with Figures 3 to 10, illustrates a solution to the problem of resource conflicts between a terminal device and other uplink information when sending a positioning SRS in a frequency hopping manner in a component carrier (CC). In actual implementation, the network device may send configuration information to the terminal device, where the configuration information includes information about multiple carriers for sending positioning SRSs and time-frequency resource information required for sending positioning SRSs on each carrier, so that the terminal device can send positioning SRSs on multiple CCs simultaneously. After the terminal device is configured to send positioning SRSs on multiple CCs simultaneously, it may also be scheduled or configured to send the first uplink information within an initial BWP or an activated BWP. The initial BWP or activated BWP may be one of the multiple CCs used to send SRSs, or the initial BWP or activated BWP may not belong to any CC. At this point, the terminal device can resolve the time domain resource conflict between the first uplink information and the positioning SRS according to the solution in method 300 or method 600.

[0126] Exemplarily, as shown in (a) of FIG11 , the terminal device is configured or scheduled to simultaneously send the positioning SRS in CC1 to CC3, and the terminal device receives the PDCCH before time T1', which schedules the terminal device to send the first uplink information in the activated BWP that coincides with CC1, and time T1' is the end time of the PDCCH. If the terminal device determines before time T2' that there is a time domain resource conflict between the first uplink information and the positioning SRS, the terminal device sends the first uplink information in the activated BWP and no longer sends the positioning SRS in multiple CCs; otherwise, the terminal device sends the positioning SRS in multiple CCs. Alternatively, as shown in (b) of FIG11 , the terminal device is configured or scheduled to simultaneously send the positioning SRS in CC1 to CC3 at time T3', and the terminal device is scheduled or configured to send the first uplink information through the initial BWP or activated BWP of CC4. If the terminal device determines before time T4' that there is a time domain resource conflict between the first uplink information and the positioning SRS, the terminal device sends the first uplink information within the initial BWP or activated BWP and no longer sends the positioning SRS in multiple CCs; otherwise, the terminal device sends the positioning SRS in multiple CCs.

[0127] The duration between T1' and T2' (or T3' and T4') may include N symbols, and the N symbols are determined according to the third subcarrier spacing. The third subcarrier spacing may be the subcarrier spacing with the smallest value among the subcarrier spacings of all CCs, or the third subcarrier spacing may be as small as possible, so that the duration between T1' and T2' (or T3' and T4') is as long as possible. More specifically, the third subcarrier spacing may be related to the capability of the terminal device. For example, when the capability of the terminal device is processing capability 1, the relationship between the third subcarrier spacing and the value of N can refer to Table 1 above. When the capability of the terminal device is processing capability 2, the relationship between the third subcarrier spacing and the value of N can refer to Table 2 above.

[0128] The above, in combination with Figures 1 to 11, illustrates the uplink transmission method provided in the embodiments of the present application. In the various embodiments of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their internal logical relationships.

[0129] The communication device provided in the embodiment of the present application is described in detail below with reference to Figures 12 to 14. It should be understood that the description of the device embodiment corresponds to the description of the method embodiment. Therefore, for matters not described in detail, reference can be made to the method embodiment above. For the sake of brevity, they will not be repeated here.

[0130] Figure 12 is a schematic block diagram of a communication device 2000 provided in an embodiment of the present application. The device 2000 includes a processing unit 2010 (or a determination module) and a transceiver unit 2020 (or a transceiver module). The transceiver unit 2020 can be used to implement corresponding transceiver functions, and the processing unit 2010 can be used to implement corresponding processing functions.

[0131] Optionally, the transceiver unit 2020 may include a sending unit and a receiving unit. The sending unit is configured to perform the sending operation in the above method embodiment. The receiving unit is configured to perform the receiving operation in the above method embodiment.

To avoid repetition, they will not be described here.

[0138] The apparatus 2000 of each of the above-mentioned solutions has the function of implementing the corresponding steps performed by the communication device (such as a terminal device) in the above-mentioned method. The functions can be implemented by hardware, or by hardware executing corresponding software implementations. The hardware or software includes one or more modules corresponding to the above-mentioned functions; for example, the transceiver unit can be replaced by a transceiver (for example, the sending unit in the transceiver unit can be replaced by a transmitter, and the receiving unit in the transceiver unit can be replaced by a receiver), and other units, such as the processing unit, can be replaced by a processor to respectively perform the sending and receiving operations and related processing operations in each method embodiment.

[0139] In addition, the transceiver unit 2020 may also be a transceiver circuit (for example, may include a transmitting circuit, or may also include a receiving circuit), and the processing unit 2010 may be a processing circuit.

[0140] It should be noted that the device in FIG12 can be a communication device (such as a terminal device) in the aforementioned embodiment, or it can be a chip or chip system, such as a system on chip (SoC). The transceiver unit can be an input / output circuit or a communication interface; the processing unit can be a processor, microprocessor, or integrated circuit integrated on the chip. This is not limited here.

[0141] FIG13 is a schematic diagram of another communication device 2100 provided in an embodiment of the present application. The device 2100 includes a processor 2110, which is coupled to a memory 2120. The memory 2120 is used to store computer programs or instructions and / or data. The processor 2110 is used to execute the computer programs or instructions stored in the memory 2120, or read the data stored in the memory 2120, to perform the methods in the above method embodiments.

[0142] Optionally, there are one or more processors 2110 .

[0143] Optionally, the memory 2120 is one or more.

[0144] Optionally, the memory 2120 is integrated with the processor 2110 or provided separately.

[0145] Optionally, as shown in Figure 13, the apparatus 2100 further includes a transceiver 2130, which is configured to receive and / or transmit signals. For example, the processor 2110 is configured to control the transceiver 2130 to receive and / or transmit signals.

[0146] As an example, the processor 2110 may have the function of the processing unit 2010 shown in FIG. 12 , the memory 2120 may have the function of a storage unit, and the transceiver 2130 may have the function of the transceiver unit 2020 shown in FIG. 12 .

[0147] As a solution, the device 2100 is used to implement the operations performed by the communication device (such as terminal equipment) in the above various method embodiments.

[0148] For example, the processor 2110 is configured to execute computer programs or instructions stored in the memory 2120 to implement relevant operations of the communication device in the above various method embodiments.

[0149] In some implementations, taking the device 2100 as a terminal device as an example, the transceiver 2130 may include a transmitter, a receiver, a radio frequency circuit, an antenna, and an input / output device. The processor 2110 is mainly used to process communication protocols and communication data, as well as to control the terminal device, execute software programs, process software program data, etc. The memory 2120 is mainly used to store software programs and data. The radio frequency circuit is mainly used to convert baseband signals and radio frequency signals and process radio frequency signals. The antenna is mainly used to transmit and receive radio frequency signals in the form of electromagnetic waves. The input / output device (for example, a touch screen, a display screen, a keyboard, etc.) is mainly used to receive data input by the user and output data to the user. It should be noted that some types of terminal devices may not have input / output devices.

[0150] When data needs to be sent, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the RF circuit.
