Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource determination method, a switching interval position determination method and a device. Background Art

[0002] In the fifth generation of mobile communication technology (5th- In the new radio (NR) of High Generation (5G), when downlink transmission is performed, the power of the network equipment (for example, the base station) is relatively large, and good downlink coverage can be achieved. However, due to the limited transmission power of the terminal equipment, the uplink coverage may be limited during uplink transmission. In order to solve the problem of limited uplink coverage of 5G NR, the industry has proposed the supplementary uplink (SUL) technology, that is, configuring an additional SUL carrier outside the normal uplink (NUL) carrier for auxiliary uplink transmission, thereby improving the uplink coverage capability and capacity. In the SUL technology, the terminal device can dynamically select the transmission link between NUL and SUL, and the switching between NUL and SUL can be understood as switching between two frequency domain resources. With the development of communication technology, the terminal device can switch between three or more frequency domain resources. The frequency domain resources to which the terminal device switches may not be used for information transmission at the same time, resulting in transmission conflicts. Summary of the invention

[0003] The present application provides a resource determination method, a switching interval position determination method and a device, which can effectively resolve transmission conflicts when the frequency domain resources switched to cannot transmit information at the same time.

[0004] In a first aspect, an embodiment of the present application provides a resource determination method, wherein the method can be executed by a terminal device, or by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The resource determination method may include:

[0005] Determine priority indication information. Exemplarily, the priority indication information is used to indicate the priority of the frequency domain resource. For example, the priority indication information indicates the priority of at least one first frequency domain resource and the priority of at least one second frequency domain resource.

[0006] The priority indication information is used to determine the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource.

[0007] When the number of second frequency domain resources in at least one second frequency domain resource is at least two and at least two second frequency domain resources cannot be used for information transmission at the same time, the frequency domain resource to be transmitted is determined from the at least two second frequency domain resources according to the priority indication information.

[0008] By implementing the method described in the first aspect, the terminal device can determine the priority indication information, and the priority indication information can be used to determine the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource. The priority indication information can also be used to determine the frequency domain resource to be transmitted from at least two second frequency domain resources switched to, thereby achieving the situation where the frequency domain resources switched to cannot communicate in an information transmission scenario at the same time, effectively resolving transmission conflicts, and multiplexing the priority indication information without the need for additional information indication, thereby saving overhead.

[0009] Alternatively, in a first aspect, an embodiment of the present application provides a resource determination method, wherein the method may be executed by a terminal device, or may be executed by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The resource determination method may include:

[0010] Switching from at least one first frequency domain resource to at least one second frequency domain resource;

[0011] When the number of the second frequency domain resources in the at least one second frequency domain resource is at least two and the at least two second frequency domain resources cannot be used for information transmission at the same time, determining the frequency domain resource to be transmitted from the at least two second frequency domain resources according to the priority indication information;

[0012] Determine, according to the priority indication information, a frequency domain resource where a switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted.

[0013] Alternatively, in a first aspect, an embodiment of the present application provides a resource determination method, wherein the method may be executed by a terminal device, or may be executed by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The resource determination method may include:

[0014] Determine priority indication information;

[0015] Determine, according to the priority indication information, a frequency domain resource where a switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource;

[0016] When the number of second frequency domain resources in the at least one second frequency domain resource is at least two and the at least two second frequency domain resources cannot be used for information transmission at the same time, the frequency domain resource to be transmitted is determined from the at least two second frequency domain resources according to the priority indication information.

[0017] In a possible implementation, the method further includes:

[0018] The priority indication information is received from a network device, where the priority indication information is carried by RRC signaling.

[0019] In implementing this method, the priority indication information can be configured by the network device to facilitate the terminal device to determine the frequency domain resources where the switching interval is located and resolve transmission conflicts.

[0020] In a possible implementation, the method further includes:

[0021] Capability information is sent to a network device, where the capability information is used to indicate that the terminal device supports using the priority indication information to determine the frequency domain resources to be transmitted when the at least two second frequency domain resources cannot be used for information transmission at the same time.

[0022] By implementing this method, the terminal device can report capability information to the network device, so that the network device can know that the terminal device supports the use of priority indication information to determine the frequency domain resources to be transmitted when the switched frequency domain resources cannot be used for information transmission at the same time, thereby resolving the transmission conflict problem.

[0023] In a possible implementation, the method further includes:

[0024] Switch from the at least one first frequency domain resource to the frequency domain resource to be transmitted.

[0025] By implementing this method, after determining the frequency domain resource to be transmitted, the terminal device switches from at least one first frequency domain resource to the frequency domain resource to be transmitted, thereby solving the transmission conflict problem of at least two frequency domain resources switched to.

[0026] In a possible implementation manner, the priority indication information includes the priority of the at least one first frequency domain resource and the priority of the frequency domain resource to be transmitted, and the method further includes:

[0027] Based on the priority of the at least one first frequency domain resource and the priority of the frequency domain resource to be transmitted, a frequency domain resource where a switching interval is located when switching from the at least one first frequency domain resource to the frequency domain resource to be transmitted is determined.

[0028] By implementing this method, the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted can be further determined according to the priority indicated in the priority indication information, thereby facilitating switching.

[0029] In one possible implementation, the frequency domain resource where the switching interval is located when switching from the at least one first frequency domain resource to the frequency domain resource to be transmitted is the at least one first frequency domain resource or the frequency domain resource to be transmitted, and the frequency domain resource where the switching interval is located when switching from the at least one first frequency domain resource to the frequency domain resource to be transmitted does not include the frequency domain resource with the highest priority among the at least one first frequency domain resource and the frequency domain resource to be transmitted.

[0030] By implementing this approach, the switching interval can be placed on the side that does not include the highest priority frequency domain resources in the switching scenario, thereby protecting the highest priority frequency domain resources.

[0031] In a possible implementation manner, when the at least one first frequency domain resource includes the frequency domain resource with the highest priority, the frequency domain resource where the switching interval is located when switching from the at least one first frequency domain resource to the frequency domain resource to be transmitted is the frequency domain resource to be transmitted;

[0032] When the frequency domain resources to be transmitted include the frequency domain resources with the highest priority or are the frequency domain resources with the highest priority, the frequency domain resources where the switching interval is located when switching from the at least one first frequency domain resource to the frequency domain resources to be transmitted are the at least one first frequency domain resource.

[0033] In a second aspect, an embodiment of the present application provides a method for determining a switching interval position, wherein the method can be executed by a terminal device, or by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The method for determining a switching interval position may include:

[0034] Determine to switch from at least one first frequency domain resource to at least one second frequency domain resource, where the information carried on the at least one second frequency domain resource includes information that is transferred from at least one third frequency domain resource to the at least one second frequency domain resource;

[0035] The frequency domain resource where the first switching interval is located is determined based on the priority of at least one first frequency domain resource and the virtual priority of at least one second frequency domain resource, and the virtual priority of at least one second frequency domain resource is higher than the priority of at least one second frequency domain resource; or, the frequency domain resource where the first switching interval is located is determined based on the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource;

[0036] The first switching interval is a switching interval for switching from at least one first frequency domain resource to at least one second frequency domain resource.

[0037] Implement the method described in the second aspect. When determining the frequency domain resources where the first switching interval for switching from at least one first frequency domain resource to at least one second frequency domain resource is located, increase the priority of the second frequency domain resources, determine the switching interval based on the increased virtual priority and the priority of the first frequency domain resources, and place the switching interval on the first frequency domain resources as much as possible, thereby ensuring that the second frequency domain resources to be followed will not be occupied due to the switching interval, and ensuring that the information followed to the second frequency domain resources can be effectively followed.

[0038] When determining the frequency domain resource where the first switching interval for switching from at least one first frequency domain resource to at least one second frequency domain resource is located, the frequency domain resource where the switching interval is located can be determined based on the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource, and the priority of the third frequency domain resource corresponding to the accompanying information, so as to place the first switching interval on the first frequency domain resource as much as possible, ensure that the second frequency domain resource to be followed will not be occupied due to the switching interval, and ensure that the information followed to the second frequency domain resource can be effectively followed.

[0039] In one possible implementation, the frequency domain resources where the first switching interval is located are the at least one first frequency domain resource or the at least one second frequency domain resource, and the frequency domain resources where the first switching interval is located do not include the frequency domain resource with the highest priority among the priority of the at least one first frequency domain resource and the virtual priority of the at least one second frequency domain resource.

[0040] When implementing this method, when determining the frequency domain resource where the first switching interval is located based on the priority of the first frequency domain resource and the virtual priority of the second frequency domain resource, the first switching interval is placed on the side where the frequency domain resource that does not contain the highest priority is located, so as to place the first switching interval on the first frequency domain resource as much as possible.

[0041] In a possible implementation manner, the frequency domain resource with the highest priority among the priority of the at least one first frequency domain resource, the priority or virtual priority of the at least one second frequency domain resource, and the priority of the at least one third frequency domain resource is a resource in the at least one first frequency domain resource, and the frequency domain resource where the first switching interval is located is the at least one second frequency domain resource; or,

[0042] The frequency domain resource with the highest priority among the priority of the at least one first frequency domain resource, the priority or virtual priority of the at least one second frequency domain resource, and the priority of the at least one third frequency domain resource is a resource in the at least one second frequency domain resource or a resource in the at least one third frequency domain resource, and the frequency domain resource where the first switching interval is located is the at least one first frequency domain resource.

[0043] By implementing this approach, when determining the frequency domain resource where the first switching interval is located, the priority of the third frequency domain resource is taken into consideration, thereby increasing the probability of placing the first switching interval on the first frequency domain resource.

[0044] In one possible implementation, the virtual priority of the at least one second frequency domain resource is the highest priority; or, the virtual priority of the at least one second frequency domain resource is the priority determined by adding a priority value increment to the priority value of the at least one second frequency domain resource.

[0045] By implementing this method, the virtual priority of the second frequency domain resource can be set to the highest priority, thereby ensuring that the frequency domain resource where the first switching interval is located is the first frequency domain resource. Alternatively, the virtual priority can be determined by increasing the priority increment based on the priority value of the second frequency domain resource, thereby increasing the probability that the frequency domain resource where the first switching interval is located is the first frequency domain resource.

[0046] In a possible implementation, the priority value increment is configured by a network device, or the priority value increment is determined by the priority of information routed from the at least one third frequency domain resource to the at least one second frequency domain resource.

[0047] By implementing this method, the priority increment value can be configured, or the priority increment value can be determined according to the priority of the associated information, thereby facilitating the determination of the virtual priority of the second frequency domain resource.

[0048] In a possible implementation manner, the determining the frequency domain resource where the first switching interval is located based on the priority of the at least one first frequency domain resource and the virtual priority of the at least one second frequency domain resource, the virtual priority of the at least one second frequency domain resource is higher than the priority of the at least one second frequency domain resource; or, determining the frequency domain resource where the first switching interval is located based on the priority of the at least one first frequency domain resource, the priority or virtual priority of the at least one second frequency domain resource, and the priority of the at least one third frequency domain resource, includes:

[0049] The start time of the information that at least one third frequency domain resource is routed to the at least one second frequency domain resource is before the end time of the second switching interval, and the frequency domain resource where the first switching interval is located is determined based on the priority of the at least one first frequency domain resource and the virtual priority of the at least one second frequency domain resource; or, the frequency domain resource where the first switching interval is located is determined based on the priority of the at least one first frequency domain resource, the priority or virtual priority of the at least one second frequency domain resource, and the priority of the at least one third frequency domain resource;

[0050] The second switching interval is a switching interval for switching from the at least one first frequency domain resource to the at least one second frequency domain resource, which is determined based on a priority of the at least one first frequency domain resource and a priority of the at least one second frequency domain resource.

[0051] To implement this method, if the start time of the information that at least one third frequency domain resource is routed to at least one second frequency domain resource is before the end of the second switching interval, it is necessary to change the method of determining the switching interval. The second switching interval is determined based on the priority of at least one first frequency domain resource and the priority of at least one second frequency domain resource, so as to be compatible with the existing method of determining the switching interval.

[0052] In a third aspect, an embodiment of the present application provides a resource determination method, wherein the method can be executed by a terminal device, or by a component of the terminal device (such as a processor, a chip, or a chip system, etc.). The resource determination method may include:

[0053] In a case where at least one first frequency domain resource is switched to at least two second frequency domain resources and the at least two second frequency domain resources cannot be used for information transmission at the same time, determining a frequency domain resource to be transmitted from the at least two second frequency domain resources;

[0054] Switch from the at least one first frequency domain resource to the frequency domain resource to be transmitted.

[0055] Implement the method described in the third aspect, and when at least two second frequency domain resources cannot be used for information transmission at the same time, determine the frequency domain resource to be transmitted from the at least two second frequency domain resources, so as to switch from at least one first frequency domain resource to the frequency domain resource to be transmitted, thereby realizing communication in a scenario where the frequency domain resource switched to cannot simultaneously carry out information transmission, thereby effectively resolving transmission conflicts.

[0056] In one possible implementation, the frequency domain resource where the first switching interval for switching from the at least one first frequency domain resource to the frequency domain resource to be transmitted is the at least one first frequency domain resource or the frequency domain resource to be transmitted, and the frequency domain resource where the first switching interval is located does not include the frequency domain resource with the highest priority among the at least one first frequency domain resource and the frequency domain resource to be transmitted.

[0110] Before introducing the method of the present application in detail, some concepts involved in the present application are briefly introduced first.

[0111] 1. SUL

[0112] In the 5G NR system, the uplink transmission of the terminal device is usually power-limited, so the received signal strength of the uplink transmission signal when it reaches the base station may not be sufficient to ensure its coverage performance. In addition, there will be insufficient UL spectrum, so it is impossible to rely on the retransmission of data to ensure its uplink coverage performance. Currently, NR introduces supplementary uplink (supplementary UL, SUL) as an alternative when the uplink coverage in the NR system is insufficient. LTE's low-frequency bands usually have better coverage performance. SUL considers using carriers from the lower frequency bands where LTE is located (for example: 700MHz, 1.8GHz, or 2.1GHz bands) for NR UL transmission. It is currently determined that when the terminal device uses the LTE band for NR transmission, it can reuse the band with LTE UL time division duplexing (TDD).

[0113] For example, when a terminal device transmits UL data on a normal uplink (NUL) (e.g., NR band 2.6 GHz), depending on channel conditions, a carrier from a lower frequency band [700 MHz, 1.8 GHz, 2.1 GHz] where LTE is located can be used for NR UL transmission, and this carrier is called SUL.

[0114] Currently, the new 4.9 GHz spectrum has the prospect of being used. This spectrum provides spectrum resources with higher bandwidth and more sufficient uplink resources. Therefore, it is possible to consider expanding uplink coverage on this spectrum as SUL 2band. 4.9 GHz can be co-sited or off-sited. Co-sited means adding a new higher frequency spectrum 4.9 GHz to the gNB (such as macro gNB), such as Figure 2a As shown in the figure, it is a schematic diagram of co-location. The gNB can use the spectrum of SUL1, SUL2 and NUL. Different-site means: the new higher-frequency spectrum 4.9GHz is used on the small cell TP (such as factory coverage), and the spectrum of SUL1 and NUL is used on the gNB (such as macro gNB). Figure 2b The schematic diagram of the different site is shown in FIG. SUL1 may refer to a lower frequency band (eg, 700 MHz, 1.8 GHz, or 2.1 GHz) where LTE is located.

[0115] Whether it is co-sited or not, it is expected that the terminal equipment can dynamically switch between multiple frequency bands (i.e. bands) of 700M / 800M / 900M, 1.8G, 2.1G, 3.5G or 4.9GHz according to the channel status and the load status of the corresponding band. This is the current flexible spectrum access technology. Among them, it involves the switching of uplink transmission of terminal equipment between three bands, four bands or more bands.

[0116] 2. Frequency band

[0117] Band originally refers to the frequency range of electromagnetic waves. In the field of communications, it refers to the frequency band of electromagnetic waves that can be used for communication. For example, a band includes one or more carriers. In this application, the terminal device reports one or more bands to the network device, and the network device selects one or more carriers from the aforementioned one or more bands and configures them to the terminal device. The terminal device uses the carrier configured by the aforementioned network device for communication.

[0118] 3. Uplink Tx Switch

[0119] Uplink RF chain switching refers to the terminal device switching the RF chain from one band (or carrier) to another band (or carrier) to support uplink transmission on the other band (or carrier). The period of time during which the uplink RF chain switching is performed is called the switching period. The switching period can also be called the switching time, or the switching gap, which is not limited here. This application uniformly refers to it as the switching gap.

[0120] The switching period is used for tuning or retuning of the RF chain. The switching period location determines which band or carrier the switching period is located in.

[0121] There can be one RF chain transmission (i.e., 1Tx or 1T) on one band (carrier), or there can be two RF chains transmission (i.e., 2Tx or 2T) on one band (or carrier). For example, one RF chain transmission on band A can be represented as A1T, and two RF chains transmission on band A can be represented as A2T. For a terminal device, it can support up to two RF chains at the same time, and the one or two RF chains can be transmitted through one port, that is, 1Tx can occur on one port, or 2Tx can occur on one port. It is determined according to the actual configuration and is not limited here.

[0122] 4. How to determine the switching period location

[0123] The terminal device can switch between two bands or two carriers, or it may switch between three or more bands or carriers. Figure 2c As shown, the terminal device may switch from frequency domain resource A and frequency domain resource B to frequency domain resource C and frequency domain resource D, where the frequency domain resource may be a band or a carrier. When it involves switching between three or more bands or carriers, a criterion is proposed for which band or carrier the switching interval position should be on: for all bands or carriers involved in a switching, the terminal device determines the switching interval position as the switching-from band(s) or switching-to / switched-to band(s) that is not the highest priority band. Figure 2c For example, if the priority order of frequency domain resource A-frequency domain resource D is that the priority of frequency domain resource D is greater than the priority of frequency domain resource C, the priority of frequency domain resource C is greater than the priority of frequency domain resource B, and the priority of frequency domain resource B is greater than the priority of frequency domain resource A. Since the highest priority among frequency domain resources A-frequency domain resource D is frequency domain resource D, frequency domain resource D is the frequency domain resource to be switched to, the switching interval position cannot be placed on the frequency domain resource to be switched to, that is, the switching interval position is placed on frequency domain resource A and frequency domain resource B, such as Figure 2d As shown, it is a schematic diagram of the switching interval position of this scenario.

[0124] If the priority order of frequency domain resource A-frequency domain resource D is that the priority of frequency domain resource A is greater than the priority of frequency domain resource B, the priority of frequency domain resource B is greater than the priority of frequency domain resource C, and the priority of frequency domain resource C is greater than the priority of frequency domain resource D. Since the highest priority among frequency domain resources A-frequency domain resource D is frequency domain resource A, and frequency domain resource A needs to be the frequency domain resource before switching, the switching interval position cannot be placed on the frequency domain resource that needs to be switched before, that is, the switching interval position is placed on frequency domain resource C and frequency domain resource D, such as Figure 2e As shown, it is a schematic diagram of the switching interval position of this scenario.

[0125] The frequency domain resources described in the embodiments of the present application may be frequency bands (i.e., bands), or may be carriers. In the embodiments of the present application, the frequency domain resources to be transmitted may be replaced by frequency domain resources of information to be transmitted. The information in the present application may include but is not limited to at least one of control information, data information, or signals.

[0126] Figure 3a is a schematic diagram of a frequency domain resource switching scenario provided in an embodiment of the present application; Figure 3aAs shown, when switching from frequency domain resource A to frequency domain resource B, if the network device also schedules information transmission on frequency domain resource C, the frequency domain resource B and frequency domain resource C cannot be used for information transmission at the same time. How the terminal device handles the transmission of frequency domain resource B and frequency domain resource C becomes a problem that needs to be solved urgently.

[0127] To solve this problem, a solution provided by an embodiment of the present application may be that the terminal device uses the priority indication information used to determine the switching interval position to determine the frequency domain resources to be transmitted in the frequency domain resources B and the frequency domain resources C. For a specific description of this specific solution, please refer to Figure 4a The description of is not repeated here.

[0128] To solve this problem, another solution provided by the embodiment of the present application may be that the terminal device determines the frequency domain resource to be transmitted according to the implementation, and it is necessary to ensure that no matter whether the terminal device selects frequency domain resource B or frequency domain resource C, the switching interval position is in the frequency domain resource before switching or the frequency domain resource after switching, and the time of the switching interval and the time of the previous switching interval and / or the next switching interval meet the prescribed switching interval limit. For a detailed description of this specific solution, please refer to Figure 6a The description of is not repeated here.

[0129] The present application is not limited to the above solution, and other solutions may also be adopted, for example, information on one frequency domain resource among frequency domain resource B and frequency domain resource C is routed to another frequency domain resource.

[0130] Figure 3b This is a schematic diagram of a routing scenario provided by an embodiment of the present application; the network device schedules information transmission on frequency domain resource A in the first time unit, and schedules information transmission on frequency domain resource B and frequency domain resource C in the second time unit (i.e., the next time unit). The physical uplink control channel (PUCCH) carried by frequency domain resource B can be routed to the physical uplink shared channel (PUSCH) on frequency domain resource C. For example, if the priority order of each frequency domain resource is the priority of frequency domain resource B>the priority of frequency domain resource A>the priority of frequency domain resource C. If the switching interval position is determined based on the priorities of the actually transmitted frequency domain resource A and frequency domain resource C, the determined switching interval position should be on the frequency domain resource C, such as Figure 3b As shown, the information on the frequency domain resource B needs to be routed to the frequency domain resource C. The condition for the route is that the start time of the information on the frequency domain resource B that needs to be routed cannot be earlier than the end time of the switching interval. Figure 3bIn the example, the start time of the information that needs to be associated with the channel on the frequency domain resource B is earlier than the end time of the switching interval, and effective association cannot be achieved. It can be understood that Figure 3b The priorities of various frequency domain resources are only for example.

[0131] To solve this problem, the present application provides a solution of increasing the priority of frequency domain resource C, thereby determining the switching interval position based on the increased virtual priority of frequency domain resource C and the priority of frequency domain resource A, so as to place the switching interval position on frequency domain resource A as much as possible.

[0132] To solve this problem, another solution provided by the present application is to determine the switching interval position based on frequency domain resource A, frequency domain resource B and frequency domain resource C, so as to place the switching interval position on frequency domain resource A as much as possible.

[0133] About Figure 3b For a detailed description of the solution, please refer to Figure 5a The description of is not repeated here.

[0134] The following examples describe the resource determination method and the switching interval position determination method of the present application. It should be noted that the various technical solutions (or embodiments) of the present application can be implemented independently or in combination based on certain internal connections. The present application is not limited thereto. And the various terms and definitions between the various embodiments can be referenced to each other. In each embodiment of the present application, different implementation methods can also be implemented in combination or independently.

[0135] Please refer to Figure 4a , which is a flow chart of a resource determination method provided in an embodiment of the present application. Figure 1 , Figure 2a , Figure 2b A system architecture diagram can be used to identify the method for this resource. Figure 4a As shown, the method may include: 101-102, wherein the execution order of each step is not limited in the embodiment of the present application. Figure 4a As shown, the resource determination method of the embodiment of the present application includes but is not limited to the following steps:

[0136] 101. Determine priority indication information, where the priority indication information is used to determine a frequency domain resource where a switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource.

[0137] The priority indication information may be used to indicate the priority of the frequency domain resource. Exemplarily, the priority indication information may indicate the priority of at least one first frequency domain resource and the priority of at least one second frequency domain resource.

[0138] In some embodiments, the priority indication information may be configured by a network device, for example, the network device sends the priority indication information to the terminal device, and correspondingly, the terminal device receives the priority indication information. The priority indication information may be carried by at least one of the following: Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, or physical layer signaling.

[0139] The terminal device can determine the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource based on the priority indication information. Among them, the frequency domain resource where the switching interval is located is at least one first frequency domain resource or at least one second frequency domain resource, and the frequency domain resource where the switching interval is located does not include the frequency domain resource with the highest priority among at least one first frequency domain resource and at least one second frequency domain resource. That is, the switching period location is the switch from band or switch to band where the highest priority is not located.

[0140] 102. When the number of second frequency domain resources in at least one second frequency domain resource is at least two and at least two second frequency domain resources cannot be used for information transmission at the same time, determine the frequency domain resource to be transmitted from at least two second frequency domain resources according to the priority indication information.

[0141] If the number of second frequency domain resources in at least one second frequency domain resource is at least two, and the at least two second frequency domain resources cannot be used for information transmission at the same time. The fact that the at least two second frequency domain resources cannot be used for information transmission at the same time can be replaced by the fact that the at least two second frequency domain resources do not support concurrent (dual UL) transmission. The fact that the at least two second frequency domain resources cannot be used for information transmission at the same time can be understood as the terminal device cannot simultaneously transmit information on the at least two second frequency domain resources. For example, it may be due to the capability limitation of the terminal device that the simultaneous information transmission on the at least two second frequency domain resources is not supported, or it may be due to the interference between the at least two second frequency domain resources that the information cannot be transmitted on the at least two second frequency domain resources at the same time.

[0142] In an embodiment of the present application, the terminal device may determine the frequency domain resource to be transmitted from at least two second frequency domain resources according to the priority indication information. For example, the frequency domain resource with the highest priority among the at least two second frequency domain resources may be used as the frequency domain resource to be transmitted; or, the frequency domain resource with a priority greater than or equal to the priority threshold among the at least two second frequency domain resources may be used as the frequency domain resource to be transmitted. The frequency domain resource to be transmitted may include one or more second frequency domain resources, which is not limited in the present application.

[0143] In some embodiments, the terminal device may report capability information to the network device, where the capability information is used to indicate that the terminal device supports using priority indication information for determining a switching interval position to determine a frequency domain resource to be transmitted when at least two second frequency domain resources cannot be used for information transmission at the same time.

[0144] In an embodiment of the present application, the priority indicated by the priority indication information can be understood as having two uses (alternatively, the use of the priority can be replaced by the meaning of the priority). The first use is to determine the switching interval position, and the second use is to determine the frequency domain resources to be transmitted when at least two frequency domain resources cannot be used for information transmission at the same time (i.e., transmission conflict). Alternatively, the above-mentioned capability information can be used to indicate that the terminal device supports the use of the second use of the priority to determine the frequency domain resources to be transmitted when a transmission conflict occurs.

[0145] In one implementation, the second use of the priority may be configured by the network device to the terminal device. For example, it may be configured to the terminal device through at least one of RRC signaling, MAC signaling, or physical layer signaling. In another implementation, the second use of the priority may also be pre-defined or default.

[0146] When determining the frequency domain resources to be transmitted, the terminal device may discard the information transmission on the frequency domain resources other than the frequency domain resources to be transmitted among the at least two second frequency domain resources. For the convenience of description, the frequency domain resources other than the frequency domain resources to be transmitted among the at least two second frequency domain resources are referred to as other second frequency domain resources. Alternatively, when determining the frequency domain resources to be transmitted, the terminal device may perform switching from at least one first frequency domain resource to the frequency domain resources to be transmitted, without performing switching from at least one first frequency domain resource to other second frequency domain resources.

[0147] Combine the following Figure 4b For example, the priority indication information indicates that the priority of frequency domain resource B>the priority of frequency domain resource A>the priority of frequency domain resource C. If frequency domain resource B and frequency domain resource C cannot be used for information transmission at the same time, the priority of frequency domain resource B is greater than the priority of frequency domain resource C, so the terminal device can transmit information on frequency domain resource B and discard the information transmission on frequency domain resource C. It can also be understood that the terminal device can switch from frequency domain resource A to frequency domain resource B, but will not switch from frequency domain resource A to frequency domain resource C.

[0148] The terminal device can switch from at least one first frequency domain resource to the frequency domain resource to be transmitted. The following example illustrates a method for determining a switching interval position when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted:

[0149] The above-mentioned priority indication information may indicate the priority of at least one first frequency domain resource and the priority of the frequency domain resource to be transmitted. The terminal device may determine the frequency domain resource in which the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted based on the priority of at least one first frequency domain resource and the priority of the frequency domain resource to be transmitted.

[0150] Among them, the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted is at least one first frequency domain resource or the frequency domain resource to be transmitted, and the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted does not include the frequency domain resource with the highest priority among the at least one first frequency domain resource and the frequency domain resource to be transmitted. Exemplarily, if the frequency domain resource with the highest priority is a frequency domain resource included in at least one first frequency domain resource, then the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted is the frequency domain resource to be transmitted. Exemplarily, if the frequency domain resource with the highest priority is the frequency domain resource to be transmitted or the frequency domain resource included in the frequency domain resource to be transmitted, then the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to the frequency domain resource to be transmitted is the at least one first frequency domain resource.

[0151] Next, continue to combine Figure 4b For example, it is necessary to switch from frequency domain resource A to frequency domain resource B. The priority of frequency domain resource B is greater than the priority of frequency domain resource A. Therefore, the switching interval is located on frequency domain resource A, such as Figure 4b The switching interval 1 is shown.

[0152] In an embodiment of the present application, the terminal device can determine priority indication information, and the priority indication information can be used to determine the frequency domain resource where the switching interval is located when switching from at least one first frequency domain resource to at least one second frequency domain resource. The priority indication information can also be used to determine the frequency domain resource to be transmitted from at least two second frequency domain resources, thereby realizing that the frequency domain resource switched to cannot communicate in an information transmission scenario at the same time, effectively resolving transmission conflicts, and multiplexing the priority indication information without the need for additional information indication, thereby saving overhead.

[0153] Please refer to Figure 5a , which is a flow chart of a method for determining a switching interval position provided in an embodiment of the present application. Figure 1 , Figure 2a , Figure 2b This is a system architecture diagram applicable to the switching interval position determination method. Figure 5a As shown, the method may include: 201-202, wherein the execution order of each step is not limited in the embodiment of the present application. Figure 5aAs shown, the method for determining the switching interval position in the embodiment of the present application includes but is not limited to the following steps:

[0154] 201, determine to switch from at least one first frequency domain resource to at least one second frequency domain resource, where information carried on the at least one second frequency domain resource includes information transferred from at least one third frequency domain resource to the at least one second frequency domain resource.

[0155] The information carried on at least one second frequency domain resource includes information that is routed to the at least one second frequency domain resource from at least one third frequency domain resource, which can be understood as placing the information on at least one third frequency domain resource on at least one second frequency domain resource for transmission without the need to transmit information on the at least one third frequency domain resource. Exemplarily, if at least one second frequency domain resource and at least one third frequency domain resource cannot transmit information at the same time, the information on at least one third frequency domain resource can be routed to at least one second frequency domain resource for transmission. Exemplarily, the information carried on at least one third frequency domain resource may include PUCCH, and the information carried on at least one second frequency domain resource may include PUSCH.

[0156] like Figure 5b As shown, at least one third frequency domain resource may include frequency domain resource B, at least one second frequency domain resource may include frequency domain resource C, and the PUCCH carried on frequency domain resource B may be routed to frequency domain resource C. The terminal device switches from frequency domain resource A to frequency domain resource C. Figure 5b In the present application, the priority order of each frequency domain resource is not limited. For example, the priority of the PUCCH carried on the frequency domain resource B can be a high priority or a low priority, which is not limited in this application.

[0157] 202. Determine the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource and the virtual priority of at least one second frequency domain resource; or, determine the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource and the priority of at least one third frequency domain resource.

[0158] Among them, the virtual priority of the second frequency domain resource is higher than the priority of the second frequency domain resource, and the priority of at least one first frequency domain resource, the priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource can be configured by the network device through priority indication information. The virtual priority of the second frequency domain resource can be the priority after the priority of the second frequency domain resource is increased.

[0159] In the present application, the priority can also be understood as the first priority; the virtual priority can also be understood as the second priority. Alternatively, the virtual priority of at least one second frequency domain resource can be replaced by the second priority of at least one second frequency domain resource, and the priority of at least one second frequency domain resource can be replaced by the first priority of at least one second frequency domain resource. In an embodiment of the present application, the second priority of the second frequency domain resource can be determined based on the first priority of the second frequency domain resource. The second priority of the second frequency domain resource is higher than the first priority of the second frequency domain resource. For example, the second priority is the highest priority, or the second priority is the priority determined by adding a priority value increment to the first priority value.

[0160] The priority of at least one first frequency domain resource can also be understood as the first priority of at least one first frequency domain resource, and the priority of at least one third frequency domain resource can also be understood as the first priority of at least one third frequency domain resource.

[0161] In some embodiments, the virtual priority of at least one second frequency domain resource may also be configured by the network device through priority indication information. Exemplarily, the network device may configure the priority of the frequency domain resource through the priority indication information, and the virtual priority of the frequency domain resource may be configured through different priority indication information, that is, configured through different signaling. It may also be configured through the same priority indication information, that is, configured through the same signaling.

[0162] When the terminal device determines that at least one second frequency domain resource contains the accompanying information, the terminal device uses the virtual priority of at least one second frequency domain resource to determine the frequency domain resource where the first switching interval is located. In this application, the accompanying can also be understood as: being accompanied by the road. That is, the accompanying can also be understood as: being accompanied by the road. The accompanying information can also be understood as: being accompanied by the road information.

[0163] In one implementation, the virtual priority of at least one second frequency domain resource is the highest priority. Since the virtual priority of at least one second frequency domain resource is the highest priority, when the frequency domain resource where the first switching interval is located is determined based on the priority of at least one first frequency domain resource and the virtual priority of at least one second frequency domain resource, it can be ensured that the switching interval position is not located on at least one second frequency domain resource, but on at least one first frequency domain resource, so that the information transmission on at least one second frequency domain resource will not be postponed, and therefore will not be later than the start time of the information on at least one third frequency domain resource, thereby achieving effective routing.

[0164] In another implementation, the virtual priority of at least one second frequency domain resource may be a priority determined by adding a priority value increment to the priority value of at least one second frequency domain resource. Exemplarily, the priority value increment may be configured by a network device, or the priority value increment may be determined based on the priority of information from at least one third frequency domain resource to at least one second frequency domain resource. As an example, the information from at least one third frequency domain resource to at least one second frequency domain resource may include at least one of the following: Hybrid Automatic Repeat reQuest (HARQ), Scheduling Request (SR), aperiodic channel state information (CSI) or periodic periodic CSI, etc. Among them, the priority of HARQ>the priority of SR>the priority of aperiodic CSI>the priority of periodic CSI.

[0165] Mode 1: Determine the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource and the virtual priority of at least one second frequency domain resource.

[0166] The frequency domain resources where the first switching interval is located are at least one first frequency domain resource or at least one second frequency domain resource, and the frequency domain resources where the first switching interval is located do not include the frequency domain resource with the highest priority among the priority of at least one first frequency domain resource and the virtual priority of at least one second frequency domain resource.

[0167] Continue with Figure 5b As an example, the terminal device switches from frequency domain resource A to frequency domain resource C, and after increasing the priority of frequency domain resource C, obtains the virtual priority of frequency domain resource C, and compares the virtual priority of frequency domain resource C with the priority of frequency domain resource A. If the virtual priority of frequency domain resource C is the highest priority, the switching interval should be placed on frequency domain resource A, such as Figure 5b As shown, it is a schematic diagram of the switching interval position. If the virtual priority of frequency domain resource C is determined by adding the priority value increment to the priority value of frequency domain resource C, the virtual priority of frequency domain resource C may be higher than the priority of frequency domain resource A, or may be lower than the priority of frequency domain resource A. If the virtual priority of frequency domain resource C is lower than the priority of frequency domain resource A, the switching interval is located on frequency domain resource C.

[0168] Method 2: determining the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource.

[0169] Although information on at least one third frequency domain resource is transmitted on at least one second frequency domain resource, when determining the position of the first switching interval, the at least one third frequency domain resource can still be counted in the frequency domain resources in the switching to determine the frequency domain resource where the switching interval is located. The frequency domain resource where the first switching interval is located is at least one first frequency domain resource or at least one second frequency domain resource.

[0170] In one implementation, the terminal device may determine the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource, the priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource. In another implementation, the terminal device may determine the frequency domain resource where the first switching interval is located based on the priority of at least one first frequency domain resource, the virtual priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource.

[0171] Exemplarily, if the frequency domain resource with the highest priority among the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource is a frequency domain resource among at least one first frequency domain resource, then the frequency domain resource where the first switching interval is located is at least one second frequency domain resource.

[0172] Exemplarily, if the frequency domain resource with the highest priority among the priority of at least one first frequency domain resource, the priority or virtual priority of at least one second frequency domain resource, and the priority of at least one third frequency domain resource is a frequency domain resource in at least one second frequency domain resource or a frequency domain resource in at least one third frequency domain resource, the frequency domain resource where the first switching interval is located is at least one first frequency domain resource.

[0173] In some implementations, if at least one third frequency domain resource carries PUCCH, the priority of the at least one third frequency domain resource is generally higher, so the determined first switching interval is usually not located on at least one second frequency domain resource. When the first switching interval is not located on at least one second frequency domain resource, it can be ensured that the start time of the information transmitted on at least one second frequency domain resource will not be later than the start time of the information carried on at least one third frequency domain resource, so as to meet the path-following requirements and realize effective path-following.

[0174] In some implementations, if the priority of at least one third frequency domain resource is not the highest, it is possible that the first switching interval is located on at least one second frequency domain resource. When the first switching interval is located on at least one second frequency domain resource, it may not meet the basic requirements of path following, that is, the start time of the information carried on at least one third frequency domain resource is earlier than the end time of the first switching interval, and effective path following cannot be achieved.

[0175] The above-mentioned method 1 and method 2 describe the method for determining the position of the first switching interval. In some embodiments, the terminal device may determine the switching interval position based on method 1 or method 2 when the start time of the information on at least one third frequency domain resource being routed to at least one second frequency domain resource is before the end time of the second switching interval. Among them, the second switching interval may be a switching interval for switching from at least one first frequency domain resource to at least one second frequency domain resource determined based on the priority of at least one first frequency domain resource and the priority of at least one second frequency domain resource. The frequency domain resource where the second switching interval is located is at least one first frequency domain resource or at least one second frequency domain resource, and the frequency domain resource where the second switching interval is located does not include the frequency domain resource with the highest priority among the priorities of at least one first frequency domain resource and at least one second frequency domain resource. In the present application, time can also be understood as a moment. The time unit may be a time slot, a subframe, a mini time slot, a mini subframe, or an orthogonal frequency division multiplexing (OFDM) symbol, etc.

[0176] In some embodiments, if the start time of the information on at least one third frequency domain resource that is routed to at least one second frequency domain resource is after the end time of the second switching interval, or if the start time of the information on at least one third frequency domain resource that is routed to at least one second frequency domain resource is the same as the end time of the second switching interval (in other words, the start time of the information on at least one third frequency domain resource that is routed to at least one second frequency domain resource is not earlier than the end time of the second switching interval), the frequency domain resource where the second switching interval is located can be determined as the frequency domain resource where the switching interval from at least one first frequency domain resource to at least one second frequency domain resource is located. Figure 5c As shown, the PUCCH carried on the frequency domain resource B can be routed to the frequency domain resource C. The start time of the PUCCH carried on the frequency domain resource B is after the end time of the second switching interval. Therefore, the second switching interval determined according to the priority of the frequency domain resource A and the priority of the frequency domain resource C can be used as the switching interval for switching from the frequency domain resource A to the frequency domain resource C this time. Figure 5cIn the present application, the priority order of each frequency domain resource is not limited. For example, the priority of the PUCCH carried on the frequency domain resource B can be a high priority or a low priority, which is not limited in this application.

[0177] Please refer to Figure 6a , which is a flow chart of a resource determination method provided in an embodiment of the present application. Figure 1 , Figure 2a , Figure 2b A system architecture diagram can be used to identify the method for this resource. Figure 6a As shown, the method may include: 301-302, wherein the execution order of each step is not limited in the embodiment of the present application. Figure 6a As shown, the resource determination method of the embodiment of the present application includes but is not limited to the following steps:

[0178] 301. When switching from at least one first frequency domain resource to at least two second frequency domain resources, and the at least two second frequency domain resources cannot be used for information transmission at the same time, determine a frequency domain resource to be transmitted from the at least two second frequency domain resources.

[0179] When at least two second frequency domain resources to be switched to cannot be used for information transmission at the same time (i.e., there is a transmission conflict), the terminal device can determine the frequency domain resource to be transmitted from at least two second frequency domain resources, and the determination method is not limited. For example, the terminal device can randomly select or arbitrarily select the frequency domain resource to be transmitted. For another example, the terminal device can select a frequency domain resource with a lower frequency point from at least two second frequency domain resources as the frequency domain resource to be transmitted, so that the resources with better coverage can be effectively utilized. For another example, the terminal device can select a frequency domain resource with a higher frequency point from at least two second frequency domain resources as the frequency domain resource to be transmitted. In view of the fact that the higher the frequency point of the frequency domain resource, the larger the bandwidth, this allows the resources with larger bandwidth to be effectively utilized. For another example, the terminal device can select a frequency domain resource with a smaller or larger index (such as bandindex or cell index) from at least two second frequency domain resources as the frequency domain resource to be transmitted. In this application, smaller can also be understood as the smallest; larger can also be understood as the largest; higher can also be understood as the highest; lower can also be understood as the lowest.

[0180] After the terminal device determines the frequency domain resources to be transmitted, it can further determine the frequency domain resources where the switching interval is located according to the priority of at least one first frequency domain resource and the priority of the frequency domain resources to be transmitted. The frequency domain resources where the switching interval is located are at least one first frequency domain resource or a frequency domain resource to be transmitted, and the frequency domain resources where the switching interval is located do not include the frequency domain resource with the highest priority among the at least one first frequency domain resource and the frequency domain resource to be transmitted.

[0181] Different frequency domain resources to be transmitted determined by the terminal device may result in different frequency domain resources in the switching interval. Figure 6b As an example, when the terminal device cannot transmit information on frequency domain resource B and frequency domain resource C at the same time, the terminal device can determine frequency domain resource B as the frequency domain resource to be transmitted, or the terminal device can also determine frequency domain resource C as the frequency domain resource to be transmitted. If the priority of frequency domain resource B>the priority of frequency domain resource A>the priority of frequency domain resource C, if the frequency domain resource to be transmitted determined by the terminal device is frequency domain resource B, then the frequency domain resource where the switching interval is located is frequency domain resource A, that is, Figure 6b The switching interval in is 1. If the frequency domain resource to be transmitted determined by the terminal device is the frequency domain resource C, then the frequency domain resource where the switching interval is located is the frequency domain resource C, that is, Figure 6b The switching interval in 2.

[0182] In an embodiment of the present application, regardless of whether the determined switching interval is on at least one first frequency domain resource or on the frequency domain resource to be switched, the network device needs to ensure that the time interval between the time of the switching interval for switching the terminal device from at least one first frequency domain resource to the frequency domain resource to be transmitted and the time of the previous switching interval satisfies the switching time interval restriction, and / or, it is necessary to ensure that the time interval between the time of the switching interval for switching the terminal device from at least one first frequency domain resource to the frequency domain resource to be transmitted and the time of the next switching interval satisfies the switching time interval restriction. Exemplarily, the switching time interval restriction may include a time interval greater than or equal to a switching time interval threshold. Exemplarily, the switching time interval restriction may be on two consecutive reference time units, if the frequency domain resources involved in the two uplink switches are more than two frequency domain resources, then the two uplink switches need to meet the minimum switching time interval. Among them, the frequency domain resources involved in the two uplink switches may be the sum of the number of frequency domain resources to which the two uplink switches are switched. For example, the first uplink switching is from frequency domain resource A to frequency domain resource B and frequency domain resource C, and the second uplink switching is from frequency domain resource B and frequency domain resource C to frequency domain resource D. The frequency domain resources involved in the two uplink switching are 3, that is, more than two frequency domain resources, and the two uplink switching need to meet the minimum switching time interval. The minimum switching time interval can be a value in the set of {0,500 microseconds}. That is, the minimum switching time interval is 0us or 500us. The above-mentioned reference time unit can be a time domain unit such as a radio frame, a subframe, a slot, a mini-slot, or at least one OFDM symbol.

[0183] In the embodiment of the present application, the frequency domain resources involved in the previous switching interval and the frequency domain resources involved in the next switching interval are not limited.

[0184] 302: Switch from at least one first frequency domain resource to the frequency domain resource to be transmitted.

[0185] The terminal device may perform switching from at least one first frequency domain resource to a frequency domain resource to be transmitted according to the frequency domain resource where the determined switching interval is located.

The transceiver is used to communicate with other devices / devices through a transmission medium.

[0216] Optionally, the communication device 2000 may also include one or more memories 2300 for storing program instructions and / or data. The memory 2300 is coupled to the processor 2200. The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which may be electrical, mechanical or other forms, and is used for information exchange between devices, units or modules. The processor 2200 may operate in conjunction with the memory 2300. The processor 2200 may execute program instructions stored in the memory 2300.

The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 8 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.
