Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0032] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof.

[0036] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0037] Multi-carrier aggregation technology

[0038] Component carrier (CC) technology aims to increase the bandwidth and data transmission rate of a communication system by aggregating multiple carriers. It allows terminal devices to transmit data simultaneously on multiple carriers, thus overcoming the bandwidth limitations of a single carrier. Because multi-carrier aggregation technology supports simultaneous transmission and reception of data across multiple frequency bands, it requires terminal devices to have multiple transceiver systems, resulting in greater complexity and power consumption for the terminal devices.

[0039] In addition, multi-carrier aggregation places high demands on filters, and it is difficult to perform good filtering on adjacent frequency bands. Therefore, carrier aggregation cannot be performed on some frequency band combinations.

[0040] As can be seen from the above introduction, carrier aggregation technology has high requirements for filters and it is difficult to perform good filtering on adjacent frequency bands. Therefore, carrier aggregation cannot be performed on some frequency band combinations. Consequently, terminal devices cannot communicate at high transmission rates on these frequency bands, which limits the utilization of these frequency bands.

[0041] Therefore, to address the aforementioned problems, this application provides a wireless communication method. In this method, a terminal device can switch between multiple frequency domain units based on first information sent by a network device to transmit data. Compared to carrier aggregation technology, the switching scheme of this application allows the terminal device to communicate based on multiple frequency domain units, which helps improve data transmission efficiency. Furthermore, the frequency domain unit switching scheme of this application does not require frequency domain unit aggregation, thus reducing the limitations on selecting frequency domain units and improving the utilization rate of frequency domain units.

[0042] The wireless communication method of this application embodiment is described below with reference to FIG2. The method shown in FIG2 includes step S210. In step S210, the network device sends first information to the terminal device, the first information being used to instruct the terminal device to switch based on multiple frequency domain units.

[0043] In some implementations, the switching of terminal devices based on multiple frequency domain units can be replaced by the switching of terminal devices based on multiple frequency domain units for transmission. That is to say, the terminal device can receive and / or send data by switching between multiple frequency domain units.

[0044] In some implementations, a frequency domain unit can be understood as the basic scheduling unit for network devices in the frequency domain.

[0045] In some implementations, the frequency domain units in a plurality of frequency domain units include one or more of the following: partial frequency domain units within a carrier; one or more carriers; one or more frequency bands; partial or all frequency domain units within a cell.

[0046] In some implementations, the frequency domain elements in a plurality of frequency domain elements include multiple carriers that are not contiguous in the frequency domain, or the frequency domain elements in a plurality of frequency domain elements include multiple carriers that are contiguous in the frequency domain.

[0047] In some implementations, the frequency domain units in a plurality of frequency domain units include multiple frequency bands that are not contiguous in the frequency domain, or the frequency domain units in a plurality of frequency domain units include multiple frequency bands that are contiguous in the frequency domain.

[0048] It should be noted that the frequency domain unit in the above-mentioned multiple frequency domain units can be understood as a specific frequency domain unit among multiple frequency domain units. In other implementations, the frequency domain unit in the multiple frequency domain units can be understood as any one of the multiple frequency domain units. In this case, it can be understood that each frequency domain unit in the multiple frequency domain units conforms to the above definition.

[0049] In some implementations, the signals transmitted in one frequency domain unit among multiple frequency domain units correspond to the same RF. Compared to carrier aggregation schemes, which require the terminal equipment to have multiple transceiver systems, this helps to reduce the cost of the terminal equipment.

[0050] In some implementations, time-frequency synchronization is achieved between signals transmitted in one frequency domain unit among multiple frequency domain units.

[0051] In some implementations, the communication times of terminal devices based on different frequency domain units in multiple frequency domain units do not overlap.

[0052] In some implementations, retransmitted data corresponding to the initial data transmitted in the first frequency domain unit among multiple frequency domain units is transmitted through the first frequency domain unit. That is to say, the initial data and the retransmitted data are transmitted through the same frequency domain unit. In this case, it can be understood that the hybrid automatic repeat request (HARQ) management between different frequency domain units in multiple frequency domain units is independent of each other.

[0053] In other implementations, retransmitted data corresponding to the initial data transmitted in the first frequency domain unit among multiple frequency domain units is transmitted through the first frequency domain unit or the second frequency domain unit among the multiple frequency domain units. That is to say, the initial data and retransmitted data can be transmitted through different or the same frequency domain units. In this case, it can be understood that different frequency domain units among multiple frequency domain units share HARQ management.

[0054] In some implementations, multiple frequency domain units can be active frequency domain units.

[0055] The frequency domain unit of the embodiments of this application has been introduced above. The first information of the embodiments of this application is described below.

[0056] In some implementations, the first information can be carried through higher-layer signaling, for example, in a radio resource control (RRC) message or a media access control element (MAC CE). Of course, in this embodiment, the first information can be carried in terminal device-specific signaling.

[0057] In some implementations, the first information is used to indicate the corresponding transmission direction of the switch. That is, the first information indicates the transmission direction in which the switch is performed, and the transmission direction can include one or more of the following: uplink transmission direction, downlink transmission direction, flexible transmission direction, and sidelink transmission direction. For example, the first information is used to indicate that the switch is performed based on multiple frequency domain units in the uplink transmission direction.

[0058] In this embodiment, the number of transmission directions corresponding to the switch indicated by the first information is not limited. In some implementations, the first information can be used to indicate switching in multiple transmission directions. For example, the first information can be used to indicate switching based on multiple frequency domain units in both the uplink and downlink transmission directions.

[0059] In some implementations, the first information is used to instruct the terminal device to switch based on multiple frequency domain units; therefore, the first information is also called the "switching command".

[0060] In some scenarios, the first information can also be used to determine the relevant timing information for switching based on multiple frequency domain units. In some implementations, the first information is used to determine one or more of the following: the switching period; the k-th time period.

[0061] Taking the use of first information to determine the switching cycle as an example, in some implementations, the first information can indicate the switching cycle by carrying one or more of the following: the duration of the switching cycle; the start time of the switching cycle; and the end time of the switching cycle. For example, the first information carries the duration of the switching cycle and the start time of the switching cycle (also known as the starting point of the switching cycle). Another example is that the first information carries the end time of the switching cycle and the start time of the switching cycle.

[0062] In some implementations, the first information may carry time offset information to determine the start time of the switching cycle, thereby indicating the start time of the switching cycle.

[0063] In some implementations, the aforementioned time offset information can indicate the time offset between the start time of the handover period and the reference system frame number (SFN). For example, the time offset information can indicate the time offset between the start time of the handover period and the start time of the reference SFN. As another example, the time offset information can indicate the time offset between the start time of the handover period and the end time of the reference SFN.

[0064] In some implementations, the aforementioned reference SFN may be indicated by a network device. For example, the network device may indicate the reference SFN through first information. Of course, in the embodiments of this application, the aforementioned reference SFN may be indicated by the network device through other information.

[0065] Furthermore, in this embodiment, the time offset information of the aforementioned start time can be determined through predefinition or preconfiguration. In this case, the first information may not indicate the time offset information (that is, the first information may not indicate the start time of the switching cycle) to reduce the overhead of transmitting the first information. For example, the time offset indicated by the aforementioned time offset information can be predefined as 0 through the protocol.

[0066] In this embodiment, the time-domain unit of the aforementioned time offset is not limited. For example, the time-domain unit corresponding to the time offset may include a symbol and / or a slot. For example, the duration of the time offset may include M1 slots and M2 symbols. Alternatively, the duration of the time offset may include M1 slots. Alternatively, the duration of the time offset may include M2 ​​symbols. Wherein, M1 and M2 are positive integers greater than or equal to 0. For example, candidate values ​​for M1 may be {0,1,2…}. Alternatively, candidate values ​​for M2 may be {0,1,2,…}. Alternatively, candidate values ​​for M2 may be {7*n, n=0,1,2…}. Alternatively, candidate values ​​for M2 may be {0,1,2,3,4,5,6,7,8,9,10,11,12,13}. For example, the preferred candidate values ​​for M1 are {0,1,2,3,4,5,6,7,8,9,10}. Of course, in this embodiment, the time unit of the time offset can also be milliseconds (ms). For example, the duration of the time offset is M3 milliseconds.

[0067] Of course, in the embodiments of this application, the start time of the handover period can be determined by predefinition or preconfiguration. In this case, the first information may not indicate the start time of the handover period to reduce the overhead of transmitting the first information. For example, the predefined information or preconfiguration information may indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0068] In this embodiment of the application, the duration of the switching cycle can be determined by predefinition or preconfiguration. In this case, the first information may not indicate the duration of the switching cycle, so as to reduce the overhead of transmitting the first information.

[0069] Furthermore, in this embodiment, the time-domain unit representing the switching period is not limited. For example, the time-domain unit corresponding to the switching period may include a symbol and / or a slot. For example, the duration of the switching period may include N1 slots and N2 symbols. Alternatively, the duration of the switching period may include N1 slots. Or, the duration of the switching period may include N2 symbols. Here, N1 and N2 are positive integers greater than or equal to 0. Of course, in this embodiment, the time-domain unit of the switching period may also be milliseconds (ms). For example, the duration of the switching period is N milliseconds, where the preferred candidate values ​​for N are {5ms, 10ms, 20ms}.

[0070] In this embodiment, the values ​​of the above parameters are not limited. For example, the candidate values ​​of N1 can be {5, 10, 20}. Another example is that the candidate values ​​of N2 can be {0, 7}. Yet another example is that the candidate values ​​of N2 can be {14*n, n = 5, 10, 20}.

[0071] Taking the first information as an indication of the kth time period as an example, in some implementations, the kth time period is the time period during which the terminal device communicates based on the lth frequency domain unit among multiple frequency domain units. Therefore, the kth time period can be understood as the duration of the lth frequency domain unit, where K≥k≥1, L≥l≥1, L represents the number of multiple frequency domain units, K represents the number of time periods corresponding to multiple frequency domain units, and L and K are positive integers greater than 1.

[0072] In some implementations, the k-th time interval can be used to indicate a period of time that is continuous in the time domain. Alternatively, the k-th time interval can be used to indicate a period of time that is discontinuous in the time domain. In this case, it can be understood that the time domain units corresponding to the frequency domain units of the k-th time interval are discontinuous.

[0073] In some implementations, the numbering of the aforementioned time periods can start from 0, in which case L-1≥l≥0, and L is a positive integer greater than 1. In other implementations, the numbering of the aforementioned frequency domain units can start from 0, in which case K-1≥k≥0, and K is a positive integer greater than 1.

[0074] In some implementations, the first information can indicate the k-th time period by carrying one or more of the following: the duration of the k-th time period; the start time of the k-th time period; and the end time of the k-th time period. For example, the first information carries the duration and start time of the k-th time period. Another example is that the first information carries the end time and start time of the k-th time period.

[0075] In some implementations, the first information may carry time offset information used to determine the start time of the kth time period within the switching cycle.

[0076] In some implementations, the aforementioned time offset information can be used to indicate the time offset between the start time of the k-th time period and the start time of the switching cycle. In other implementations, the aforementioned time offset information can be used to indicate the time offset between the start time of the k-th time period and the start time of the (k-1)-th time period, where the K time periods are arranged in ascending order of their indices, from earliest to latest in the time domain. That is to say, the aforementioned time offset can be the time offset between the start time of the k-th time period and the start time of the previous time period.

[0077] Of course, in this embodiment, the aforementioned time offset information can be used to indicate the time offset between the start time of the k-th time period and the end time of the switching cycle. Alternatively, the aforementioned time offset information can be used to indicate the time offset between the start time of the k-th time period and the end time of the (k-1)-th time period, wherein the K time periods are arranged from early to late in the time domain according to their indexes in ascending order. That is to say, the aforementioned time offset can be the time offset between the start time of the k-th time period and the end time of the previous time period.

[0078] In some implementations, the start time of the first time segment (or the earliest time segment in the time domain) among the K time segments can be the same as the start time of the switching cycle. Alternatively, the start time of the time segment corresponding to the first frequency domain unit (i.e., the time segment corresponding to this frequency domain unit is earlier than the time segments corresponding to other frequency domain units) among the L frequency domain units can be the same as the start time of the switching cycle. In this case, the first information no longer needs to indicate the time offset used to determine the start time of that time segment, thus reducing the overhead of transmitting the first information. In this case, the value range of k can be expressed as k≥2.

[0079] In this embodiment, the time-domain unit of the time offset is not limited. For example, the time-domain unit corresponding to the time offset may include a symbol and / or a slot. For example, the duration of the time offset may include N3 slots and N4 symbols. Alternatively, the duration of the time offset may include N3 slots. Or, the duration of the time offset may include N4 symbols. Here, N3 and N4 are positive integers greater than or equal to 0. Of course, in this embodiment, the time-domain unit of the time offset may also be milliseconds (ms). For example, the duration of the time offset is N5 milliseconds, where N5 is a positive number.

[0080] In some implementations, the first information can indicate the k-th time period by indicating a first pattern. The first pattern is used to indicate the frequency domain units corresponding to the K time periods within the switching cycle, or in other words, the first pattern is used to indicate the time periods corresponding to multiple frequency domain units within the switching cycle. In some scenarios, the first pattern is also called a "frequency domain unit pattern".

[0081] In this application embodiment, the method for determining the effective time of the first drawing is not limited. In some implementations, the effective time of the first drawing can be determined based on the start time of the reference SFN. For example, the effective time of the first drawing can be equal to the start time of the reference SFN.

[0082] In some implementations, the effective time of the first pattern can be determined based on the start time of the switching cycle. For example, the effective time of the first pattern can be equal to the start time of the switching cycle.

[0083] In some implementations, the effective time of the first pattern can be determined based on time offset information. In some implementations, the aforementioned time offset information can indicate the time offset between the effective time and the reference SFN.

[0084] In this embodiment, the time offset information used to determine the effective time can be determined through predefinition or preconfiguration. In this case, the first information may not indicate the time offset information used to determine the effective time, thereby reducing the overhead of transmitting the first information. For example, the time offset indicated by the time offset information can be predefined as 0 through the protocol.

[0085] In this embodiment, the time-domain unit used to determine the effective time is not limited. For example, the time-domain unit corresponding to the time offset may include a symbol and / or a slot. Of course, in this embodiment, the time-domain unit of the time offset may also be milliseconds (ms).

[0086] In this application embodiment, the method for determining the length of the first pattern is not limited. In some implementations, the length of the first pattern can be predefined. For example, predefined information can indicate that the length of the first pattern is 10. In other implementations, the length of the first pattern can be determined based on the length of the switching cycle. For example, the length of the first pattern is the number of time slots within the switching cycle.

[0087] In some implementations, the first information can be indicated by a bitmap. For example, the i-th bit in the bitmap is used to indicate whether the l-th frequency domain unit in the i-th time domain unit is used during the switching cycle, where i ≥ 0. It should be understood that the correspondence between bits in the bitmap and frequency domain units can be determined based on the switching order or configuration order of multiple frequency band units. Of course, in the embodiments of this application, the network device can configure the above correspondence for the terminal device.

[0088] In this embodiment, the granularity of the time-domain unit indicated by the bitmap is not limited. In some implementations, the time-domain unit may include a symbol or a time slot. Taking the granularity as a symbol as an example, the length of the bitmap is S*14. Taking the granularity as a time slot as an example, the length of the bitmap is S, where S is a positive integer.

[0089] For example, suppose multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, the granularity of the bitmap is time slots, the length of the bitmap is 10, and the bitmap is represented as [1010101010]. Based on the bitmap, it can be determined that if the odd-numbered bits in the bitmap are 1, it indicates that communication is based on the first frequency domain unit in the time slot corresponding to the odd-numbered bits. If the even-numbered bits in the bitmap are 0, it indicates that communication is based on the second frequency domain unit in the time slot corresponding to the even-numbered bits.

[0090] In this embodiment of the application, the duration of the kth time period can be determined by predefinition or preconfiguration. In this case, the first information may not indicate the duration of the kth time period in order to reduce the overhead of transmitting the first information.

[0091] Furthermore, in this embodiment, the time-domain unit representing the k-th time period is not limited. For example, the time-domain unit corresponding to the k-th time period may include a symbol and / or a slot. For example, the duration of the k-th time period may include N5 slots and N6 symbols. For another example, the duration of the k-th time period may include N5 slots. For another example, the duration of the k-th time period may include N6 symbols. Where N5 and N6 are positive integers greater than or equal to 0. For example, candidate values ​​for N6 may be {14*n, n=0,1,2,3,4,5,6,7,8,9,10}. For another example, candidate values ​​for N6 may be {0,1,2,3,4,5,6,7,8,9,10,11,12,13}. For another example, candidate values ​​for N5 may be {0,1,2,3,4,5,6,7,8,9,10}. Of course, in this embodiment, the time unit of the kth time period can also be milliseconds (ms). For example, the duration of the kth time period is N milliseconds.

[0092] Additionally, it should be noted that in some implementations, the duration of the k-th time period can be less than the switching period. In this case, the terminal device can communicate based on multiple frequency domain units within the switching period, as described below with reference to Figures 3 to 8. In other implementations, the duration of the k-th time period can be equal to the switching period. In this case, the terminal device can communicate based on one frequency domain unit within the switching period, as described below with reference to Figures 9 and 10.

[0093] The foregoing described the scheme for indicating the switching of relevant time information in the embodiments of this application. The embodiments of this application do not limit the combination of the above information. For ease of understanding, several schemes for indicating the switching of relevant time information are described below with reference to Examples 1 to 5.

[0094] Example 1: The first information is used to indicate the start time of the switching cycle, the duration of the switching cycle, and the time offset between the start time of the time period corresponding to other frequency domain units in the multiple frequency domain units and the start time of the switching cycle. Among them, other frequency domain units can refer to the frequency domain units other than the first frequency domain unit in the time domain (or, the frequency domain unit with the earliest time position in the multiple frequency domain units).

[0095] It should be noted that the start time of the time period corresponding to the first frequency domain unit is the same as the start time of the switching cycle. Therefore, the first information does not need to indicate the start time of the time period corresponding to the first frequency domain unit, so as to reduce the overhead of transmitting the first information.

[0096] For example, referring to Figure 3, multiple frequency domain units include frequency domain unit 1, frequency domain unit 2, and frequency domain unit 3. During the switching period, the time domain resources corresponding to frequency domain unit 1 are earlier than the time domain resources corresponding to frequency domain unit 2 and frequency domain unit 3. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching period. The first information indicates the duration T of the switching period, the time offset 1 between the start time of the switching period and the reference SFN is 0, the time offset 2 between the start time of the time segment corresponding to frequency domain unit 2 and the start time of the switching period, and the time offset 3 between the start time of the time segment corresponding to frequency domain unit 3 and the start time of the switching period.

[0097] In some implementations, it is assumed that multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and that the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching cycle. The first information is used to indicate the start time of the switching cycle, the time offset between the start time of the time period corresponding to the second frequency domain unit and the start time of the switching cycle, and the duration of the switching cycle.

[0098] For example, referring to Figure 4, the first frequency domain unit is frequency domain unit 1, and the second frequency domain unit is frequency domain unit 2. During the switching cycle, the time domain resources corresponding to frequency domain unit 1 are earlier than the time domain resources corresponding to frequency domain unit 2. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching cycle. The first information indicates that the time offset 1 between the start time of the switching cycle and the reference SFN is 0, the time offset 2 between the start time of the time period corresponding to frequency domain unit 2 and the start time of the switching cycle, and the duration T of the switching cycle.

[0099] In some implementations, the first information may no longer indicate the start time of the switching period to reduce the transmission overhead of the first information. For example, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching period. The first information is used to indicate the time offset between the start time of the time period corresponding to the second frequency domain unit and the start time of the switching period, as well as the duration of the switching period.

[0100] For example, the first information is used to indicate the duration of the switching cycle and the time offset between the start time of the time period corresponding to other frequency domain units in the multiple frequency domain units and the start time of the switching cycle. The other frequency domain units can refer to the frequency domain units other than the first frequency domain unit in the time domain (or the frequency domain unit with the earliest time position in the multiple frequency domain units).

[0101] In some implementations, the start time of the handover period can be determined through predefinition or preconfiguration. For example, predefined or preconfigured information can indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0102] It should be noted that the above first piece of information can be applied to scenarios where the time period corresponding to the frequency domain unit within the switching cycle is continuous.

[0103] Example 2: The first information is used to indicate the start time of the switching cycle, the duration of the switching cycle, and the time period corresponding to other frequency domain units in the multiple frequency domain units. Among them, other frequency domain units can refer to the frequency domain units other than the last frequency domain unit in the time domain (or, the frequency domain unit with the latest time position in the multiple frequency domain units).

[0104] It should be noted that the start time of the time period corresponding to the first frequency domain unit (or the frequency domain unit with the earliest time domain position among multiple frequency domain units) is the same as the start time of the switching cycle. Therefore, the first information does not need to indicate the start time of the time period corresponding to the first frequency domain unit, so as to reduce the overhead of transmitting the first information.

[0105] In some implementations, the time periods corresponding to two adjacent frequency domain units within multiple frequency domain units can be continuous in the time domain. In this case, after determining the start time of the time period corresponding to the first frequency domain unit, and combining this with the duration of the time period indicated by the first information, the time period corresponding to the first frequency domain unit can be determined. Then, based on the end time of the time period corresponding to the first frequency domain unit, the start time of the time period of the next frequency domain unit adjacent to the first frequency domain unit (i.e., the second frequency domain unit) can be determined; that is, the end time of the time period corresponding to the first frequency domain unit is the same as the start time of the time period corresponding to the second frequency domain unit. Then, combining this with the duration of the time period corresponding to the second frequency domain unit indicated by the first information, the time period corresponding to the second frequency domain unit can be determined. This process continues until the time period corresponding to each frequency domain unit within the multiple frequency domain units can be determined.

[0106] For example, referring to Figure 5, multiple frequency domain units include frequency domain unit 1, frequency domain unit 2, and frequency domain unit 3. During the switching period, the time domain resources corresponding to frequency domain unit 1 are earlier than those corresponding to frequency domain unit 2 and frequency domain unit 3. The start time of frequency domain unit 1 is the same as the start time of the switching period. The first information indicates the duration T of the switching period, the time offset 1 between the start time of the switching period and the reference SFN is 0, the duration of the time period corresponding to frequency domain unit 1 is T1, and the duration of the time period corresponding to frequency domain unit 2 is T2. Thus, based on the switching period, the duration of the time period corresponding to frequency domain unit 1 (T1), and the duration of the time period corresponding to frequency domain unit 2 (T2), the duration of the time period corresponding to frequency domain unit 3 can be determined as T3. In this case, the first information may not indicate the duration of the time period corresponding to frequency domain unit 3 to reduce the overhead of transmitting the first information.

[0107] In some implementations, it is assumed that multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and that the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching period. The first information is used to indicate the start time of the switching period, the duration of the time period corresponding to the first frequency domain unit, and the duration of the switching period.

[0108] For example, referring to Figure 6, the first frequency domain unit is frequency domain unit 1, and the second frequency domain unit is frequency domain unit 2. During the switching period, the time domain resources corresponding to frequency domain unit 1 are earlier than those corresponding to frequency domain unit 2. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching period. The first information indicates the duration T of the switching period, the time offset 1 between the start time of the switching period and the reference SFN is 0, the duration of the time period corresponding to frequency domain unit 1 is T1, and the duration of the time period corresponding to frequency domain unit 2 is T2. Thus, based on the switching period, the duration of the time period corresponding to frequency domain unit 1 is T1, and the duration of the time period corresponding to frequency domain unit 2 is T2. In this case, the first information may not indicate the duration of the time period corresponding to frequency domain unit 2 to reduce the overhead of transmitting the first information.

[0109] In some implementations, the first information may no longer indicate the start time of the switching period to reduce the transmission overhead of the first information. For example, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching period. The first information is used to indicate the duration of the time period corresponding to the first frequency domain unit and the duration of the switching period.

[0110] For example, the first information is used to indicate the duration of the switching cycle and the time period corresponding to other frequency domain units in the multiple frequency domain units. The other frequency domain units can refer to the frequency domain units other than the last frequency domain unit in the time domain (or the frequency domain unit with the latest time position in the multiple frequency domain units).

[0111] In some implementations, the start time of the handover period can be determined through predefinition or preconfiguration. For example, predefined or preconfigured information can indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0112] It should be noted that the above first piece of information can be applied to scenarios where the time period corresponding to the frequency domain unit within the switching cycle is continuous.

[0113] Example 3: The first information is used to indicate the start time of the switching cycle, the duration of the switching cycle, and the duration of the time period corresponding to each frequency domain unit in the multiple frequency domain units.

[0114] In some implementations, a switch gap can be used to separate the time periods of two adjacent frequency domain units in the time domain. This switch gap is used by the terminal device to perform the handover. For a more detailed explanation of the switch gap, please refer to the following text.

[0115] For example, referring to Figure 7, multiple frequency domain units include frequency domain unit 1, frequency domain unit 2, and frequency domain unit 3. During the switching period, the time domain resources corresponding to frequency domain unit 1 are earlier than those corresponding to frequency domain unit 2 and frequency domain unit 3. The start time of frequency domain unit 1 is the same as the start time of the switching period. The first information indicates the duration T of the switching period. The time offset 1 between the start time of the switching period and the reference SFN is 0. The duration of the time period corresponding to frequency domain unit 1 is T1, the duration of the time period corresponding to frequency domain unit 2 is T2, and the duration of the time period corresponding to frequency domain unit 3 is T3. Furthermore, there is a switching interval between the time periods corresponding to frequency domain unit 1 and frequency domain unit 2, and between the time periods corresponding to frequency domain unit 2 and frequency domain unit 3.

[0116] In some implementations, it is assumed that multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and that the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching cycle. The first information is used to indicate the start time of the switching cycle, the duration of the time period corresponding to the first frequency domain unit, the duration of the time period corresponding to the second frequency domain unit, and the duration of the switching cycle.

[0117] For example, referring to Figure 8, the first frequency domain unit is frequency domain unit 1, and the second frequency domain unit is frequency domain unit 2. During the switching cycle, the time domain resources corresponding to frequency domain unit 1 are earlier than those corresponding to frequency domain unit 2. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching cycle. The first information indicates the duration T of the switching cycle, the time offset 1 between the start time of the switching cycle and the reference SFN is 0, the duration of the time period corresponding to frequency domain unit 1 is T1, and the duration of the time period corresponding to frequency domain unit 2 is T2. Additionally, there is a switching interval between the time periods corresponding to frequency domain unit 1 and frequency domain unit 2.

[0118] In some implementations, the first information may no longer indicate the start time of the switching cycle, thereby reducing the transmission overhead of the first information. For example, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and within the switching cycle, the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit. The first information is used to indicate the duration of the time period corresponding to the first frequency domain unit, the duration of the time period corresponding to the second frequency domain unit, and the duration of the switching cycle.

[0119] For example, the first information is used to indicate the duration of the switching cycle and the duration of the time period corresponding to each frequency domain unit in the multiple frequency domain units.

[0120] In some implementations, the start time of the handover period can be determined through predefinition or preconfiguration. For example, predefined or preconfigured information can indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0121] It should be noted that the above first piece of information can be applied to scenarios where the time period corresponding to the frequency domain unit within the switching cycle is continuous.

[0122] Example 4: The first information is used to indicate the start time of the switching cycle, the duration of the switching cycle, and the first pattern.

[0123] For example, assuming multiple frequency domain units include frequency domain unit 1 and frequency domain unit 2, the first information is used to indicate the start time of the switching cycle, the duration of the switching cycle, and the first pattern. The first information indicates the first pattern by carrying a bitmap, where the granularity of the bitmap is a time slot, the length of the bitmap is 10, and the bitmap is represented as [1010101010]. Based on the bitmap, it can be determined that communication is based on the first frequency domain unit within the time slots corresponding to odd-numbered bits, and communication is based on the second frequency domain unit within the time slots corresponding to even-numbered bits.

[0124] In other implementations, the first information may no longer indicate the start time of the switching cycle, in order to reduce the transmission overhead of the first information. For example, the first information is used to indicate the duration of the switching cycle, the first pattern.

[0125] In some implementations, the start time of the handover period can be determined through predefinition or preconfiguration. For example, predefined or preconfigured information can indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0126] It should be noted that the aforementioned first information can be applied to scenarios where the time periods corresponding to the frequency domain units within the switching cycle are discontinuous. Of course, in the embodiments of this application, the aforementioned first information can also be applied to scenarios where the time periods corresponding to the frequency domain units within the switching cycle are continuous.

[0127] Example 5: The first piece of information indicates the start time and duration of the switching cycle, where the switching cycle is the switching cycle of multiple frequency domain units. That is to say, within each switching cycle, only one frequency domain unit is used among the multiple frequency domain units, and if the switching cycle ends, it switches to other frequency domain units.

[0128] For example, referring to Figure 9, multiple frequency domain units include frequency domain unit 1, frequency domain unit 2, and frequency domain unit 3. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching cycle. The first information indicates the duration T of the switching cycle and the start time of the switching cycle. Thus, communication is performed based on frequency domain unit 1 during switching cycle 1. Communication is performed based on frequency domain unit 2 during switching cycle 2. Communication is performed based on frequency domain unit 3 during switching cycle 3.

[0129] In some implementations, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the switching period is the switching period between the first frequency domain unit and the second frequency domain unit. The first information is used to indicate the start time of the switching period and the duration of the switching period.

[0130] For example, referring to Figure 10, multiple frequency domain units include frequency domain unit 1 and frequency domain unit 2. Furthermore, the start time of frequency domain unit 1 is the same as the start time of the switching cycle. The first information indicates the duration T of the switching cycle and the start time of the switching cycle. Thus, communication is performed based on frequency domain unit 1 during switching cycle 1, and based on frequency domain unit 2 during switching cycle 2.

[0131] In some implementations, the first information may no longer indicate the start time of the switching period, in order to reduce the transmission overhead of the first information. For example, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the switching period is the switching period between the first frequency domain unit and the second frequency domain unit, with the first information used to indicate the duration of the switching period.

[0132] For example, the first information is used to indicate the duration of the switching period, where the switching period is the switching period of multiple frequency domain units.

[0133] In some implementations, the start time of the handover period can be determined through predefinition or preconfiguration. For example, predefined or preconfigured information can indicate that the start time of the handover period is subframe 0 or slot 0 within the radio frame.

[0134] It should be noted that the above first piece of information can be applied to scenarios where the time period corresponding to the frequency domain unit within the switching cycle is continuous.

[0135] The foregoing section described the scheme for indicating the relevant handover time based on the first information in the embodiments of this application. The following section describes the handover interval in the embodiments of this application.

[0136] In some implementations, handover based on multiple frequency domain units is performed within a handover interval. For example, handover based on multiple frequency domain units may be performed at the start time of the handover interval. Alternatively, handover based on multiple frequency domain units may be performed at the end time of the handover interval.

[0137] In some implementations, the start and / or end times of the switching interval can be at the boundary of the time slot, or the start and / or end times of the switching interval can be within the time slot.

[0138] It should be noted that the embodiments of this application do not limit the length of the handover interval. For example, when the time-domain unit of the handover interval is μs, the length G of the handover interval can be 13, 35, or 140. As another example, when the time-domain unit of the handover interval is a symbol, for a 15kHz subcarrier interval, the length G of the handover interval can be 1, 1, or 2; for a 30kHz subcarrier interval, the length G of the handover interval can be 1, 1, or 4; and for a 60kHz subcarrier interval, the length G of the handover interval can be 1, 2, or 8. As yet another example, when the time-domain unit of the handover interval is a time slot, for 15kHz, 30kHz, and 60kHz subcarrier intervals, the length G of the handover interval can be 1.

[0139] In some implementations, the terminal device expects the length of the first time interval to be greater than or equal to the duration of the handover interval; in other words, the terminal device does not expect the length of the first time interval to be less than the duration of the handover interval. Here, the first time interval is the time interval between the end time of the transmission of the first data and the start time of the transmission of the second data, where the first data is the last data transmitted before the handover, and the second data is the first data transmitted after the handover.

[0140] In other words, the terminal device expects not to receive or send data during the first time interval. In this way, the terminal device can switch during the switching interval to avoid the terminal device being unable to receive or send data due to the switching, which would lead to data transmission failure.

[0141] In some implementations, the above method further includes: if the length of the first time interval is less than the duration of the handover interval, the terminal device discards the data received or sent during the handover interval, or in other words, the terminal device stops receiving or sending data during the handover interval, or in other words, the terminal device abandons receiving or sending data during the handover interval.

[0142] In this embodiment, if the length of the first time interval is less than the duration of the switching interval, the switching may conflict with the data reception or transmission process. In this case, the terminal device can use the above-described operation to avoid the conflict.

[0143] In some implementations, the terminal device discards data received or transmitted during the handover interval, including: the terminal device discards data received or transmitted during the handover interval according to the frequency domain resource configuration of the handover interval.

[0144] For example, the terminal device is configured to switch transmissions between a first frequency domain unit and a second frequency domain unit, and the frequency domain resource configuration of the switching interval indicates that the frequency domain resources of the switching interval are located in the first frequency domain unit. When the length of the first time interval is less than the duration of the switching interval, the terminal device may discard data received or transmitted that occupies frequency domain resources on the first frequency domain unit that overlap with the switching interval.

[0145] In some implementations, the handover is performed within a handover interval, and the frequency domain resources of the handover interval are used to determine the time of the handover interval; in other words, the frequency domain resources of the handover interval correspond to the time of the handover interval. The following sections will describe methods 1 and 2 in conjunction with these methods.

[0146] In Method 1, Case 1, if the frequency domain resources of the switching interval partially or completely overlap with the target frequency domain unit of the switching, the time of the switching interval is determined based on the start time of the switching cycle.

[0147] In the embodiments of this application, the method for determining the start time of the switching interval is not limited. In some implementations, the start time of the switching interval may be the same as the start time of the switching cycle. In other implementations, the start time of the switching interval may be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0148] Referring to Figure 11, assuming that the switching order of the frequency domain units is from the source frequency domain unit to the target frequency domain unit, and the frequency domain resources of the switching interval are located in the target frequency domain unit, then the start time of the switching interval is the start time of the switching cycle.

[0149] In Method 1 and Case 2, if the frequency domain resources of the switching interval partially or completely overlap with the source frequency domain units of the switching, the end time of the switching interval is determined based on the start time of the switching cycle.

[0150] In the embodiments of this application, the method for determining the end time of the switching interval is not limited. In some implementations, the end time of the switching interval may be the same as the start time of the switching cycle. In other implementations, the end time of the switching interval may be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0151] Referring to Figure 12, assuming that the switching order of the frequency domain units is from the source frequency domain unit to the target frequency domain unit, and the frequency domain resources of the switching interval are located in the source frequency domain unit, then the end time of the switching interval is the start time of the switching cycle.

[0152] Method 2, Case 1: The frequency domain resources of the switching interval and the switching direction are used to determine the time of the switching interval.

[0153] In some implementations, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the frequency domain resources of the switching interval partially or completely overlap with the first frequency domain unit. If the switching direction is from the first frequency domain unit to the second frequency domain unit, the end time of the switching interval is determined based on the start time of the switching cycle. Conversely, if the switching direction is from the second frequency domain unit to the first frequency domain unit, the start time of the switching interval is determined based on the start time of the switching cycle.

[0154] In the embodiments of this application, the method for determining the end time of the switching interval is not limited. In some implementations, the end time of the switching interval is the same as the start time of the switching cycle. In other implementations, the end time of the switching interval can be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0155] Furthermore, the method for determining the start time of the switching interval is not limited in the embodiments of this application. In some implementations, the start time of the switching interval is the same as the start time of the switching cycle. In other implementations, the start time of the switching interval can be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0156] Referring to Figure 13, assume the switching sequence based on frequency domain units is from frequency domain unit 1 to frequency domain unit 2, and the frequency domain resources of the switching interval belong to frequency domain unit 1. In this case, the end time of the switching interval is the start time of the switching cycle. Alternatively, assume the switching sequence based on frequency domain units is from frequency domain unit 2 to frequency domain unit 1, and the frequency domain resources of the switching interval belong to frequency domain unit 1. In this case, the start time of the switching interval is the start time of the switching cycle.

[0157] In Method 2, Case 2, multiple frequency domain units include a first frequency domain unit and a second frequency domain unit, and the frequency domain resources of the handover interval partially or completely overlap with those of the second frequency domain unit. If the handover direction is from the first frequency domain unit to the second frequency domain unit, the start time of the handover interval is determined based on the start time of the handover period. Conversely, if the handover direction is from the second frequency domain unit to the first frequency domain unit, the end time of the handover interval is determined based on the start time of the handover period.

[0158] In the embodiments of this application, the method for determining the end time of the switching interval is not limited. In some implementations, the end time of the switching interval is the same as the start time of the switching cycle. In other implementations, the end time of the switching interval can be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0159] Furthermore, the method for determining the start time of the switching interval is not limited in the embodiments of this application. In some implementations, the start time of the switching interval is the same as the start time of the switching cycle. In other implementations, the start time of the switching interval can be obtained by taking the start time of the switching cycle as the start time and then adjusting for time offset.

[0160] Referring to Figure 14, assume the switching sequence based on frequency domain units is from frequency domain unit 1 to frequency domain unit 2, and the frequency domain resources of the switching interval belong to frequency domain unit 2. In this case, the start time of the switching cycle is the start time of the switching interval. Alternatively, assume the switching sequence based on frequency domain units is from frequency domain unit 2 to frequency domain unit 1, and the frequency domain resources of the switching interval belong to frequency domain unit 2. In this case, the start time of the switching cycle is the end time of the switching interval.

[0161] In some implementations, the frequency domain resources of the handover interval can be configured by the network device for the terminal device. Of course, in this embodiment, the frequency domain resources of the handover interval can be determined based on predefined rules or preconfiguration rules. For example, predefined rules or preconfiguration rules can be used to indicate that the frequency domain resources of the handover interval are located in the source frequency domain cell. As another example, predefined rules or preconfiguration rules can be used to indicate that the frequency domain resources of the handover interval are located in the target frequency domain cell.

[0162] In this application embodiment, the method for obtaining the switching order of multiple frequency domain units is not limited. In some implementations, the switching order corresponding to multiple frequency domain units is determined based on the configuration order of the multiple frequency domain units. For example, the switching order corresponding to multiple frequency domain units is the same as the configuration order of the multiple frequency domain units. Another example is that the switching order corresponding to multiple frequency domain units is the reverse of the configuration order of the multiple frequency domain units.

[0163] For example, the terminal device can determine the handover order based on the Low Bandwidth Carrier Aggregation Handover (LBCASwitch feature). Assume the LBCASwitch feature indicates multiple carriers as {n5A, n29A}. In this case, if the configuration order corresponds to the handover order, the carrier handover order is from carrier n5A to n29A. It should be understood that the names of the above configurations are not limited in this application embodiment.

[0164] For example, suppose a frequency domain unit is a carrier, and the carrier configuration order is {band A, band B, ..., band N}. If the switching order corresponding to multiple frequency domain units is the same as the configuration order of multiple frequency domain units, then the switching order is represented as {band A, band B, ..., band N}.

[0165] In other implementations, the switching order of multiple frequency domain units can be indicated by the network device. That is, the above method further includes: the network device sending second information to the terminal device, the second information indicating the switching order corresponding to the multiple frequency domain units. In the embodiments of this application, the second information and the first information can be the same or different information.

[0166] For example, a network device can indicate the carriers before and after the switch using bits in the second indication information. For instance, assuming the LBCASwitch feature indicates multiple carriers as {n5A, n29A}, the network device can indicate the carriers before and after the switch using bits in the second indication information; that is, a bit value of 1 indicates the source carrier is n5A, and a bit value of 0 indicates the target carrier is n29A. It should be understood that the embodiments of this application do not limit the names of the above configurations.

[0167] The method embodiments of this application have been described in detail above with reference to Figures 1 to 14. The apparatus embodiments of this application will be described in detail below with reference to Figures 15 to 17. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0168] Figure 15 is a schematic diagram of a terminal device according to an embodiment of this application. The terminal device 1500 shown in Figure 15 includes a receiving unit 1510.

[0169] The receiving unit 1510 is used to receive first information sent by the network device, the first information being used to instruct the terminal device to switch based on multiple frequency domain units.

[0170] In some implementations, the first information is used to determine one or more of the following: a switching cycle; a k-th time period, wherein the k-th time period is the time period during which the terminal device communicates based on the l-th frequency domain unit among the plurality of frequency domain units, where K≥k≥1, L≥l≥1, L represents the number of the plurality of frequency domain units, and K represents the number of time periods corresponding to the plurality of frequency domain units.

[0171] In some implementations, the first information carries one or more of the following: the duration of the switching period; the start time of the switching period; the duration of the kth time period; the start time of the kth time period; the end time of the kth time period; information for determining the time offset of the start time of the kth time period within the switching period, wherein k≥2; and a first pattern, which is used to indicate the frequency domain units corresponding to the K time periods within the switching period.

[0172] In some implementations, the plurality of frequency domain units include a first frequency domain unit and a second frequency domain unit, and the time domain resources corresponding to the first frequency domain unit are earlier than the time domain resources corresponding to the second frequency domain unit during the switching period. The first information is used to indicate the start time of the switching period, the time offset between the start time of the time period corresponding to the second frequency domain unit and the start time of the switching period, and the duration of the switching period.
