[0002] This application claims priority to Chinese Patent Application No. 202410803545.X, filed on June 20, 2024, entitled “Frame Parameter Determination and Configuration Method, Storage Medium and Communication Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of wireless communication technology, and in particular to a method for determining and configuring frame parameters, a storage medium, and a communication device. Background Technology

[0004] Frame parameters (Numerology) are defined by subcarrier spacing and cyclic prefix (CP) overhead, and also involve determining a series of related parameters such as sampling rate and Fast Fourier Transform (FFT) size. Compared to Long Term Evolution (LTE), New Radio (NR), in pursuit of higher capacity and data rates, supporting more available spectrum, and larger continuous bandwidth, extends the usable frequency bands to a higher frequency range. This requires defining corresponding subcarrier spacing for the spectral characteristics of different frequency ranges.

[0005] For future communication systems, such as 6G, the target scenarios are more diverse, posing new requirements for frame parameter design. For example, with the evolution of waveform technology, in some waveform designs, adding filters or inserting static sequences can save CP overhead, and even achieve zero CP overhead, i.e., a CP-free design. Furthermore, more resources can be used for data transmission within a data transmission slot. For example, a slot may have 15 symbols. Another potential future network deployment is de-cellularization. In this network, terminals obtain network services from one or more access points in their vicinity, and the access points serving the terminals change accordingly as the terminals move. Compared to traditional cellular networks, the distance between the terminal and the access point is shorter, resulting in less transmission latency spread and thus a lower requirement for CP length. Reducing CP overhead is also a consideration. Finally, future systems may be networks that integrate communication and sensing, where sensing typically requires receiving the echo of a transmitted signal after it encounters a target object to estimate the target's physical motion state. Compared to communication, this involves twice the transmission latency, thus the required CP length differs from that of communication. Therefore, how to design a CP that accommodates both communication and sensing requirements is a problem that needs to be addressed.

[0006] Therefore, a technical solution for flexibly configuring frame parameters is needed in related technologies. Summary of the Invention

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] Both 4G (4th generation) Long Term Evolution (LTE) and 5G (5th generation) Radio Access (NR) systems are based on Orthogonal Frequency Division Multiplexing (OFDM). To overcome the inter-symbol interference (ISI) inherent in OFDM systems, the concept of CP (Carrier Component) overhead is introduced from LTE, with the CP length related to the coverage radius. LTE only supports one carrier spacing, i.e., 15kHz. CP overhead is defined as Normal CP (NCP) and Extended CP (ECP) to meet different coverage requirements. Under normal circumstances, it is set to NCP. When the coverage area is large, it is configured as ECP.

[0041] In NR systems, the time domain length is measured in time domain units T. c =1 / (Δf) max ·N f Let Δf be used to express this, where Δf is the value of Δf. max =480·10 3 Hz, N f =4096. Constant k = T s / T c =64, where T s =1 / (Δf) ref ·N f,ref ), Δf ref =15·103 Hz and N f,rdf =2048. Frame parameters (Numerology) are defined by the subcarrier spacing and cyclic prefix (CP) overhead. Multiple subcarrier spacings are defined, and these spacings are obtained by scaling a reference subcarrier spacing. The reference subcarrier spacing is defined as 15kHz and scaled by 2... m As a scaling factor, higher frequencies and larger bandwidths are supported. As shown in Table 1, other subcarrier spacings (SCS) are derived from the reference SCS, such as 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, and 960kHz. NCP supports all SCS, while ECP is only supported at 60kHz.

[0042] Table 1.

[0043] In an exemplary embodiment, as described by the following formula, the CP length of the first symbol of each 0.5ms in the NCP case is defined as (144k·2 -μ +16k)×T c The CP length of the remaining symbols is defined as (144k·2). -μ )×T c The data portion of each symbol is (2048k·2). -μ )×T c In the case of ECP, the CP length of each symbol is defined as (512k·2). -μ )×T c The data portion of each symbol is (2048k·2). -μ Compared to NCP, a larger CP length can withstand greater multipath delay spread and provide greater coverage.

[0044] In another exemplary embodiment, one subframe is defined as 1 ms. For a 15 kHz subcarrier spacing, one subframe includes 14 NCP symbols or 12 ECP symbols. As shown in Figure 1, under the NCP configuration, there are 14 symbols in the subframe. For each 0.5 ms first symbol, i.e., the first or seventh symbol in the subframe, the CP length is approximately 5.2 μs (i.e., (144 μs·2 μs)). 0 +16κ)×T C =160κ×T C The CP length of each remaining symbol in the subframe is approximately 4.7 μs (i.e., (144κ·2)). 0 )×T C =144κ×T CThe length of the data portion of a symbol in a subframe is 66.7 μs (i.e., (2048κ·2)). 0 )×T C =2048κ×T C For a subframe with ECP symbols, as shown in Figure 2, there are 12 symbols in a subframe. For each symbol in the subframe, the CP length is approximately 16.7 μs (i.e., (512κ·2)). 0 )×T C =512κ×T C The length of the data portion of a symbol in a subframe remains 66.7 μs (i.e., (2048κ·2)). 0 )×T C =2048κ×T C ).

[0045] For future communication systems, such as 6G, the target scenarios are more diverse, posing new requirements for frame parameter design. For example, with the evolution of waveform technology, in some waveform designs, adding filters or inserting static sequences can save CP overhead, and even achieve zero CP overhead, i.e., a CP-free design. Furthermore, more resources can be allocated to data transmission within a data transmission slot. For example, a slot may contain 15 symbols. Another potential network deployment form is decellularization. In this network, terminals obtain network services from one or more access points in their vicinity, and the access points serving them change accordingly as the terminals move. Compared to traditional cellular networks, the distance between the terminal and the access point is shorter, resulting in less transmission latency spread and thus a lower requirement for CP length. Reducing CP overhead is also a consideration. Furthermore, future systems may be networks that integrate communication and sensing. Sensing typically requires receiving the echo of a transmitted signal after it encounters a target object to estimate the target's physical motion state. Compared to communication, this involves twice the transmission latency, resulting in a different CP length requirement. At this point, how to design a CP that accommodates both communication and sensing requirements is also a problem that needs to be solved.

[0046] To address the increasingly diverse needs mentioned above, a problem that needs to be solved is how to define the CP length more flexibly.

[0047] To address the above problems, the embodiments of this application provide the following solutions.

[0048] Figure 3 shows a flowchart of a frame parameter determination method provided by an exemplary embodiment of this application. As shown in Figure 3, the method mainly includes the following steps.

[0049] S310, the terminal receives frame parameter configuration information sent by the network-side device, wherein the first time unit includes a plurality of second time units, and the frame parameter configuration information is used to indicate the frame parameter configuration of each of the second time units in the first time unit, and the frame parameter configurations of the plurality of second time units in the first time unit are not completely the same.

[0050] S312, the terminal determines the frame parameters or frame parameter patterns of each second time unit based on the frame parameter configuration information, wherein the frame parameters include at least one of the following: subcarrier spacing, cyclic prefix type, cyclic prefix length, and cyclic prefix overhead.

[0051] In the technical solution provided by the embodiments of this application, the terminal receives frame parameter configuration information sent by the network-side device. The first time unit includes multiple second time units, and the frame parameter configuration information indicates the frame parameter configuration of each second time unit within the first time unit. The frame parameter configurations of the multiple second time units within the first time unit are not completely identical. The terminal determines the frame parameters of each second time unit based on the frame parameter configuration information. This allows for flexible configuration of different frame parameters for each second time unit within the same first time unit.

[0052] In this embodiment of the application, a first time unit and a second time unit are defined, wherein the first time unit includes a plurality of second time units. As shown in FIG4, schematically, the first time unit includes 5 second time units.

[0053] Optionally, the first time unit or the second time unit can be defined as one of the following: absolute time length (e.g., in milliseconds, the absolute time length may be the same or different under different subcarrier intervals), number of symbols, number of radio frames, number of half frames, number of subframes, number of time slots, number of transmission units, etc.

[0054] Optionally, the second time unit can have multiple types of symbol composition methods. That is, in this embodiment of the application, multiple symbol composition methods can be defined within the second time unit, and the second time unit is composed of one or more symbols. The symbol composition methods of multiple second time units within the first time unit may be the same or different.

[0055] Optionally, the symbols of the i-th second time units in each of the first time units are composed in the same way, where i = 1, 2, ..., N, and N is the number of second time units contained in a first time unit. That is, the first time units composed of different types of second time units appear periodically, meaning that the symbols of the i-th second time units in each of the first time units are composed in the same way.

[0056] In some examples, the frame parameter configuration information includes the frame parameter configurations for each of the second time units of the first time unit.

[0057] Optionally, multiple second time units within the same first time unit may have various frame parameter configurations, and the frame parameter configurations of each symbol within the same second time unit may be the same. For example, the subcarrier spacing of the symbols contained within the second time unit may be the same; the subcarrier spacing of different second time units within the first time unit may be different. Another example is that the CP type / CP overhead of the symbols contained within the second time unit may be the same; the CP type / CP overhead of different second time units within the first time unit may be different. Yet another example is that the number of symbols contained within the second time unit may be the same; the number of symbols contained in different second time units within the first time unit may be different. As shown in Figure 5, the first time unit contains different types of second time units; wherein the first type of second time unit contains 7 15kHz NCP symbols, and the second type of second time unit contains 14 30kHz NCP symbols. As shown in Figure 6, the third type of second time unit contains 7 15kHz NCP symbols, and the second type of second time unit contains 6 15kHz ECP symbols.

[0058] In some implementations, the frame parameters of the i-th second time unit of each first time unit are configured identically, where i = 1, 2, ..., N, and N is the number of second time units contained in a first time unit. In these implementations, the first time units composed of different types of second time units occur periodically, that is, the frame parameters of the i-th second time unit of each first time unit are configured identically.

[0059] In some examples, the frame parameter configuration information may include a frame parameter pattern configured based on the second time unit. That is, the frame parameter configuration information is a frame parameter pattern configured based on the second time unit.

[0060] In some embodiments, the frame parameter configuration information may include frame parameter patterns configured for each of the second time units based on a first time unit. Therefore, one of the following can be configured differently for the symbols contained within a second time unit: subcarrier spacing, CP type, and CP overhead. Consequently, the number of symbols contained within a second time unit can be the same or different. Multiple frame parameter patterns are predefined, and frame parameter patterns are configured for all second time units within the first time unit. In an exemplary embodiment, the frame parameter pattern used is configured separately for each second time unit.

[0061] In some embodiments, a plurality of second time units within a first time unit are divided into a plurality of second time unit groups. The frame parameter configuration information includes frame parameter patterns configured based on each of the second time unit groups within a first time unit, wherein a second time unit group includes at least one second time unit. That is, the second time units within the first time unit are divided into multiple groups, and the frame parameter configuration information configures the frame parameter patterns used for each group of second time units.

[0062] As shown in Figure 7, the first type of frame parameter pattern of the second time unit is defined as containing 6 ECP symbols and 7 NCP symbols, as shown in formula (2); the second type of frame parameter pattern of the second time unit is defined as 14 NCP symbols.

[0063] As shown in Figure 8, another type of frame parameter pattern for the second time unit is defined as a comb-like arrangement of long and short CP lengths within the second time interval. The CP length of even-numbered symbols is greater than the CP length of odd-numbered symbols. In an exemplary embodiment, the CP length of each data symbol is as shown in formula (3).

[0064] The frame structure diagrams and values ​​listed above are merely examples; the method is also applicable to other predefined or configured combinations of frame parameters. That is, it includes all possible combinations of subcarrier spacing and CP length defined for different symbols within the second time unit.

[0065] In some embodiments, the frame parameter patterns of the i-th second time units of each of the first time units are identical, where i = 1, 2, ..., N, and N is the number of second time units contained in a first time unit. In these embodiments, the first time units composed of different types of second time units appear periodically, that is, the frame parameter patterns of the i-th second time units of each of the first time units are configured identically.

[0066] In some implementations, the frame parameter pattern included in the frame parameter configuration information is a reference frame parameter pattern configured based on the reference subcarrier spacing; the terminal determining the frame parameter pattern of each second time unit based on the frame parameter configuration information may include: the terminal scaling the configured reference frame parameter pattern based on the ratio of the subcarrier spacing corresponding to each second time unit to the reference subcarrier spacing to obtain the frame parameter pattern of each second time unit.

[0067] In these implementations, the frame parameter pattern can be configured based on a reference subcarrier spacing, for example, referred to as a reference frame parameter pattern; the frame parameter patterns for other subcarrier spacings can be obtained by scaling the reference frame parameter pattern. As shown in Figure 9, a 15kHz symbol corresponds to two 30kHz symbols under the same CP type / CP overhead.

[0068] In some implementations, the frame parameter configuration information further includes uplink and downlink frame structures configured based on the reference frame parameter pattern; the method may further include: the terminal determining the uplink and downlink frame structures under the frame parameter pattern used by each of the second time units based on the uplink and downlink frame structures of the reference frame parameter pattern.

[0069] In these implementations, the uplink and downlink frame structures can be configured based on a reference frame parameter pattern, and the uplink and downlink frame structures under the actual frame parameter pattern can be derived based on the uplink and downlink frame structures of the reference frame parameter pattern.

[0070] In some embodiments, the uplink and downlink frame structures of the reference frame parameter pattern are configured based on the reference subcarrier spacing and the reference cyclic prefix type. In these embodiments, the uplink and downlink frame structures can be configured based on the reference subcarrier spacing and the reference CP type, and the uplink and downlink frame structures under other subcarrier spacings or CP types can be derived. For example, symbols under the actual used frame parameter pattern that overlap with downlink symbols of the reference frame parameter pattern are also defined as downlink symbols, and symbols under the actual used frame parameter pattern that overlap with uplink symbols of the reference frame parameter pattern are defined as uplink symbols. When a symbol under the actual used frame parameter pattern overlaps with both downlink symbols under the reference frame parameter pattern and flexible symbols under the reference frame structure pattern, the symbol under the actual used frame parameter pattern is defined as a downlink symbol. When a symbol under the actual used frame parameter pattern overlaps with both uplink symbols under the reference frame parameter pattern and flexible symbols under the reference frame structure pattern, the symbol under the actual used frame parameter pattern is defined as an uplink symbol. When a symbol in the actual used frame parameter pattern only overlaps with a flexible symbol in the reference frame parameter pattern, the symbol in the actual used frame parameter pattern is defined as a flexible symbol. The terminal does not expect a symbol in the actual used frame parameter pattern to overlap with both an uplink symbol in the reference frame parameter pattern and a downlink symbol in the reference frame structure pattern.

[0071] As shown in Figure 10, under the reference frame structure pattern, the second time unit contains 14 symbols, and its frame structure is configured as DDDDDDFFFUUUUU; while under the actual frame parameter pattern, the second time unit contains 15 symbols. Symbols 0-6 under the actual frame parameter pattern either overlap only with the downlink symbols under the reference frame parameter pattern, or overlap with both the downlink symbols under the reference frame parameter pattern and the flexible symbols under the reference frame structure pattern; therefore, these symbols are defined as downlink symbols. Symbols 9-14 under the actual frame parameter pattern either overlap only with the uplink symbols under the reference frame parameter pattern, or overlap with both the uplink symbols under the reference frame parameter pattern and the flexible symbols under the reference frame structure pattern; therefore, these symbols are defined as uplink symbols. Symbols 7 and 8 under the actual frame parameter pattern overlap only with the flexible symbols under the reference frame parameter pattern; therefore, they are defined as flexible symbols.

[0072] In some embodiments, the frame parameter configuration information may include uplink and downlink frame structures configured for the second time units other than those of a specific type; or, the frame parameter configuration information may include uplink and downlink frame structures configured for all second time units, and the terminal does not expect to transmit information on the specific type of second time unit; or, the frame parameter configuration information may include uplink and downlink frame structures configured for all second time units, and the terminal does not expect to transmit information on a specific type of symbol within the second time unit. In these embodiments, uplink and downlink frame structures are configured only for the second time units other than those of a specific type. Alternatively, uplink and downlink frame structures are configured for all second time units, and the UE does not expect to receive or transmit information within a specific type of second time unit, thus the UE ignores the uplink and downlink frame structures configured for that specific type of second time unit. Alternatively, uplink and downlink frame structures are configured for all second time units, and the UE does not expect to receive or transmit information on a specific type of symbol within the second time unit, thus the UE ignores the uplink and downlink frame structures configured for that specific type of symbol.

[0073] In the above embodiments, a second time unit of a specific type may include: a second time unit of a specific cyclic prefix type or a second time unit at a specific position. For example, the specific cyclic prefix type includes an extended cyclic prefix; the specific position includes the first or last second time unit within the first time unit; or, several preceding or following second time units. A specific type symbol may be a symbol at a specific position within the second time unit, for example, the first or last symbol of the second time unit, or several preceding or following symbols of the second time unit, or one or more symbols within the second time unit indicated by signaling.

[0074] This application provides a flexible method for configuring frame parameter patterns, which can adapt well to different transmission requirements, thereby improving data transmission efficiency.

[0075] Figure 11 shows a flowchart of a frame parameter configuration method according to an exemplary embodiment of this application. This method can be executed by a network-side device. This method is a technical solution executed by a network-side device corresponding to the frame parameter determination method shown in Figure 3, and has the same or corresponding implementation methods as the above-described frame parameter determination method. The following mainly describes the relevant technical solutions involving the network-side device. For other matters not covered, please refer to the description of the relevant parts in the above-described frame parameter determination method, which will not be repeated here.

[0076] As shown in Figure 11, the frame parameter configuration method mainly includes the following steps.

[0077] S1110, the network-side device sends frame parameter configuration information to the terminal, wherein the first time unit includes multiple second time units, and the frame parameter configuration information is used to indicate the frame parameter configuration of each second time unit in the first time unit, and the frame parameter configurations of the multiple second time units in the first time unit are not completely the same.

[0078] Optionally, the first time unit and the second time unit are defined as one of the following: absolute time length, number of symbols, number of radio frames, number of half frames, number of subframes, number of time slots, and number of transmission units.

[0079] Optionally, the second time unit can have various types of symbol composition methods.

[0080] Optionally, the symbols of the i-th second time unit in each of the first time units are composed in the same way, where i = 1, 2, ..., N, and N is the number of second time units contained in a first time unit.

[0081] In some implementations, the frame parameter configuration information may include the frame parameter configurations for each of the second time units of the first time unit.

[0082] In some embodiments, multiple second time units within the same first time unit may have multiple frame parameter configurations, and the frame parameter configurations of each symbol within the same second time unit may be the same.

[0083] In some implementations, the frame parameter configuration information may include a frame parameter pattern configured based on the second time unit.

[0084] In some embodiments, the frame parameter configuration information includes frame parameter patterns configured based on each of the second time units of a first time unit.

[0085] In other embodiments, the frame parameter configuration information includes frame parameter patterns configured based on various second time unit groups of a first time unit, wherein a plurality of second time units of a first time unit are divided into a plurality of second time unit groups, and a second time unit group includes at least one second time unit of a first time unit.

[0086] Optionally, the frame parameter pattern included in the frame parameter configuration information is a reference frame parameter pattern configured based on the reference subcarrier spacing.

[0087] In some implementations, the frame parameter configuration information may also include uplink and downlink frame structures that can be configured based on the reference frame parameter pattern.

[0088] Optionally, the uplink and downlink frame structures of the reference frame parameter pattern can be configured based on the reference subcarrier spacing and the reference cyclic prefix type.

[0089] In some implementations, the frame parameter configuration information includes uplink and downlink frame structures configured for the second time units other than those of a specific type; or, the frame parameter configuration information includes uplink and downlink frame structures configured for all the second time units.

[0090] This application provides a flexible method for configuring frame parameter patterns, which can adapt well to different transmission requirements, thereby improving data transmission efficiency.

[0091] Figure 12 shows a flowchart of a method for determining time-domain resources provided in an exemplary embodiment of this application. The method can be executed by a terminal. As shown in Figure 12, the method mainly includes the following steps.

[0092] S1210, the terminal receives configuration information sent by the network-side device, wherein the configuration information is used to configure a first time domain resource, wherein the first time domain resource includes one of the following: unavailable time domain resource, sensing time domain resource;

[0093] S1211, the terminal determines the second time domain resource based on the configuration information.

[0094] In this embodiment, the second time-domain resource may be the same as or different from the first time-domain resource. The second time-domain resource may include one of the following: an unavailable time-domain resource or a perceived time-domain resource.

[0095] In this embodiment of the application, after the second time domain resource is determined, during the data transmission process, the terminal does not perform data transmission on the second time domain resource, that is, the terminal performs data transmission on time domain resources other than the second time domain resource.

[0096] In the technical solutions provided in the embodiments of this application, based on the conventional uplink and downlink frame structure configuration of user data communication, some time-domain resources are additionally configured as unavailable time-domain resources or sensing time-domain resources. These unavailable or sensing time-domain resources can then be used for other purposes, but are unavailable for data communication. In an exemplary embodiment, symbols used for data communication often require shorter CP types, while symbols used for sensing often require longer CP types. The above solution allows for flexible configuration of the frame structure based on the frame parameters of data communication (including subcarrier spacing and symbol type). Furthermore, by configuring the positions of unavailable or sensing time-domain resources, the frame structure can be rewritten, thereby enabling the definition of flexible combination patterns of different symbol types for service transmissions requiring a mixture of long and short CP symbols.

[0097] In this embodiment, based on the conventional uplink and downlink frame structure configuration for user data communication, an additional portion of time-domain resources are configured as unavailable time-domain resources or perceived time-domain resources. Optionally, the first and second time-domain resources can be defined by one of the following time-domain units: such as symbols, time slots, subframes, half-frames, radio frames, microseconds, milliseconds, etc. In this embodiment, most subsequent cases are described using symbols as an example, and thus the unavailable time-domain resources or perceived time-domain resources can be unavailable symbols or perceived symbols.

[0098] In this embodiment, optionally, the terminal does not wish to transmit data on the second time-domain resource; and / or, the terminal ignores the uplink / downlink frame structure configuration on the unavailable time-domain resource or the sensing time-domain resource. For example, on the unavailable symbol or sensing symbol, the terminal does not wish to receive or send information. Furthermore, the terminal can ignore the uplink / downlink frame structure configuration on the unavailable symbol or sensing symbol. As shown in FIG13, on a resource of 14 symbols, the uplink / downlink frame structure is configured as DDDDDFFFUUUUU. Symbols 5, 6, and 7 are additionally configured as unavailable symbols or sensing symbols via signaling. These unavailable symbols or sensing symbols can be used for other purposes, such as sensing, and are therefore unavailable symbols or sensing symbols for data communication.

[0099] In some implementations, the configuration information may include:

[0100] 1) Period, used to indicate the period during which the first time-domain resource appears.

[0101] 2) Offset, used to indicate the starting point of the first time-domain resource in each cycle.

[0102] 3) Quantity, used to indicate the quantity of the first time-domain resource in each period.

[0103] In the above implementation, the unusable symbols or sensing symbols are configured using a period, an offset, and a quantity. For example, the period is 14 symbols (or one time slot), meaning the period in which unusable symbols or sensing symbols appear is 14 symbols; the offset is used to determine the starting point of the unusable symbols or sensing symbols in each period, that is, the position of the first unusable symbol or sensing symbol in the period. If the offset is 5, then the 6th symbol (i.e., symbol #5) is the first unusable symbol or sensing symbol; if the quantity of unusable symbols or sensing symbols is 3, then symbols 5, 6, and 7 are unusable symbols or sensing symbols.

[0104] In other embodiments, the configuration information may include:

[0105] 1) Period, used to indicate the period during which the first time-domain resource appears.

[0106] 2) A bitmap, used to indicate whether each time-domain unit within a period is the first time-domain resource, or to indicate whether each time-domain unit within a period contains the first time-domain resource.

[0107] In the above implementation, unusable symbols or perceived symbols are configured using a period and a bitmap. For example, the period is 14 symbols (or one time slot), meaning that the period for unusable symbols or perceived symbols to appear is 14 symbols. The bitmap consists of 14 bits of information, with each bit corresponding to one symbol within the period. The value of the bit indicates whether the corresponding symbol is an unusable symbol or a perceived symbol. Schematic, a bit value of '0' represents that it is not an unusable symbol or a perceived symbol, and '1' represents an unusable symbol or a perceived symbol. Therefore, by setting the bitmap to 00000111000000, symbols 5, 6, and 7 are identified as unusable symbols or perceived symbols.

[0108] In other embodiments, a period and a bitmap are used to configure unusable symbols or sensed symbols. For example, the period is a number of time slots, such as 10 time slots, meaning the period in which unusable symbols or sensed symbols appear is 10 time slots. The bitmap is 10 bits of information, with each bit corresponding to one time slot within the period. The value of the bit indicates the time slot location of the unusable symbol or sensed symbol. Schematic, a bit value of '0' represents that the time slot does not contain an unusable symbol or sensed symbol, and '1' represents that the time slot contains an unusable symbol or sensed symbol. Therefore, by setting the bitmap to 0001110000, it is obtained that the 4th, 5th, and 6th time slots within the period contain unusable symbols or sensed symbols. Furthermore, which symbols within a time slot containing unusable or perceived symbols are unusable or perceived symbols can be predefined, for example, the first N symbols can be predefined as unusable or perceived symbols; alternatively, they can be configured via signaling, for example, using a 14-bit bitmap where each bit corresponds to a symbol within a time slot, and the bit value indicates whether the corresponding symbol is unusable or perceived. Illustratively, a bit value of '0' represents that the symbol is not unusable or perceived, and '1' represents that it is unusable or perceived. Thus, by setting the bitmap to 00000111000000, symbols 5, 6, and 7 are identified as unusable or perceived symbols. Consequently, within the ten-time-slot indication period, symbols 5, 6, and 7 in the 4th, 5th, and 6th time slots are identified as unusable or perceived symbols.

[0109] In some implementations, the configuration information is used to indicate predefined rules for determining the first time-domain resource. In this implementation, for example, the location of unavailable symbols or sensing symbols is determined using predefined rules. The number of unavailable symbols or sensing symbols can be predefined or indicated by signaling. For example, the starting symbol of an unavailable symbol or sensing symbol can be predefined as the first flexible symbol, or the ending symbol can be predefined as the last flexible symbol. If the number of symbols is predefined or configured to be three, then the range of unavailable symbols or sensing symbols is obtained by continuing the predefined or configured number of symbols backward or forward from the starting / ending symbol. Similarly, it can also be defined that the starting point of the starting symbol of an unavailable symbol or sensing symbol is aligned with the start of the time slot, or the ending symbol of an unavailable symbol or sensing symbol is aligned with the end of the time slot.

[0110] In some implementations, the configuration information can directly configure unavailable time-domain resources or sensing resources during data transmission; that is, the second time-domain resource is the same as the first time-domain resource. In other implementations, the configuration information can be configured based on first frame parameters, which are different from second frame parameters, wherein the second frame parameters are frame parameters used for uplink and downlink data communication. Therefore, in these implementations, the terminal can determine the second time-domain resource based on the first time-domain resource when performing uplink and downlink data communication.

[0111] Optionally, in the above embodiments, the terminal determines the target time-domain resource as a second time-domain resource based on the configuration information, including:

[0112] Step 1: The terminal determines the first time domain resource under the first frame parameters based on the location and quantity of the first time domain resource indicated by the configuration information.

[0113] Step 2: Determine the time domain unit that overlaps with the first time domain resource under the second frame parameters as the target time domain resource.

[0114] In the above embodiments, the network-side device can configure the frame parameters (e.g., frame parameter 1) used for unusable symbols or sensed symbols to be different from the frame parameters (e.g., frame parameter 2) used for symbols used for uplink and downlink data communication. That is, the network-side frame parameter 1 configures the position and number of the unusable symbols or sensed symbols, and the terminal further determines which data communication symbols under frame parameter 2 are unusable symbols or sensed symbols based on the configuration. For example, symbols under frame parameter 2 that at least partially overlap with the unusable symbols or sensed symbols under frame parameter 1 are defined as unusable symbols or sensed symbols under frame parameter 2. As shown in Figure 14, under the frame parameters used by the terminal for data communication, a certain transmission time unit (e.g., a time slot) contains 14 symbols (e.g., NCP), while under the frame parameters used for configuring unusable symbols or sensed symbols, the same transmission time unit contains 12 symbols (e.g., ECP), and symbols 5 and 6 are configured as unusable symbols or sensed symbols. For the frame parameters of data communication, symbols 5, 6, 7, and 8 all overlap with the configured unusable symbols or perceived symbols. Therefore, symbols 5, 6, 7, and 8 under the data communication frame parameters are defined as unusable symbols or perceived symbols under data communication.

[0115] In some implementations, the configuration information includes the starting point of the first temporal resource configured based on the second frame parameters and the number of the first temporal resources configured based on the first frame parameters.

[0116] In the above implementation, the network-side device can configure the starting point of unusable or sensed symbols based on frame parameter 1, and configure the number of unusable or sensed symbols based on frame parameter 2. As shown in Figure 15, the starting symbol of the unusable or sensed symbols configured with frame parameter 1 (e.g., the frame parameter used for data communication) is symbol 5, and the number of unusable or sensed symbols configured with frame parameter 2 is 2. Then, symbols 5, 6, and 7 under frame parameter 1 all overlap with the configured unusable or sensed symbols. Therefore, symbols 5, 6, and 7 are defined as unusable or sensed symbols under frame parameter 1.

[0117] Through the embodiments of this application, the introduction of sensing time-domain resources does not affect the normal configuration of frame parameters. Therefore, frame parameter patterns can be flexibly configured to suit different transmission requirements, thereby improving the efficiency of data transmission.

[0118] Figure 16 shows a flowchart of a time-domain resource configuration method according to an exemplary embodiment of this application. This method can be executed by a network-side device. This method is a technical solution executed by a network-side device corresponding to the time-domain resource determination method shown in Figure 12, and has the same or corresponding implementation methods as the above-described time-domain resource determination method. The following mainly describes the relevant technical solutions involving the network-side device. For other matters not covered, please refer to the description of the relevant parts in the above-described time-domain resource determination method, which will not be repeated here.

[0119] As shown in Figure 16, the configuration method of this time-domain resource mainly includes the following steps.

[0120] S1610, the network-side device sends configuration information to the terminal, wherein the configuration information is used to configure a first time domain resource, wherein the first time domain resource includes one of the following: unavailable time domain resource, sensing time domain resource.

[0121] In this embodiment of the application, after sending the configuration information to the terminal, the network-side device can determine the second time-domain resource corresponding to the first time-domain resource during the data transmission process based on the first time-domain resource. The network-side device does not perform data communication with the terminal on the second time-domain resource, that is, the network-side device performs data communication with the terminal on time-domain resources other than the second time-domain resource.

[0122] Optionally, the first time-domain resource includes a predetermined number of time-domain units of one of the following: symbol, time slot, subframe, half-frame, radio frame, microsecond, and millisecond.

[0123] In some implementations, the configuration information may include:

[0124] 1) Period, used to indicate the period during which the first time-domain resource appears.

[0125] 2) Offset, used to indicate the starting point of the first time-domain resource in each cycle.

[0126] 3) Quantity, used to indicate the quantity of the first time-domain resource in each period.

[0127] In other embodiments, the configuration information may include:

[0128] 1) Period, used to indicate the period during which the first time-domain resource appears;

[0129] 2) A bitmap, used to indicate whether each time-domain unit within a period is the first time-domain resource, or to indicate whether each time-domain unit within a period contains the first time-domain resource.

[0130] In some implementations, the configuration information may be used to indicate predefined rules for determining the first time-domain resource.

[0131] In some implementations, the configuration information can directly configure unavailable time-domain resources or sensing resources during data transmission, meaning the second time-domain resource is the same as the first time-domain resource. In other implementations, the configuration information can be configured based on first frame parameters, which are different from the second frame parameters, where the second frame parameters are frame parameters used for uplink and downlink data communication. Therefore, in these implementations, when the terminal and network-side devices perform uplink and downlink data communication, they can determine the second time-domain resource based on the first time-domain resource and the second frame parameters, thereby avoiding data communication on the second time-domain resource.

[0132] In other embodiments, the configuration information may include the starting point of the first time-domain resource configured based on the second frame parameters and the quantity of the first time-domain resource configured based on the first frame parameters. In these embodiments, the network-side device and the terminal may determine the starting point of the first time-domain resource based on the second frame parameters, and determine the quantity of the first time-domain resource based on the first frame parameters.

[0133] The technical solutions provided in the embodiments of this application allow for flexible configuration of frame parameter patterns to adapt to different transmission requirements, thereby improving the efficiency of data transmission.

[0134] This application also provides a method for flexibly configuring cyclic prefixes. In an exemplary embodiment, for short-distance transmission, such as within decellularized cells, a low CP overhead mode is defined, where more resources are used for data transmission to improve spectral efficiency.

[0135] In this embodiment, the time-domain resources saved by CP can be used to form additional OFDM symbols without changing the length of the data portion within a symbol.

[0136] In one example of an embodiment of this application, the first time interval can be defined as 2×2. -μ ms, where μ corresponds to the subcarrier interval as shown in Table 1. The first time interval contains 29 symbols, i.e., symbol #0 to symbol #28. The CP length of the first symbol in the first time interval is different from the CP lengths of all other symbols in the first time interval. In some instances, as shown in formula (4), where L is the symbol index in the first time interval, T... C The basic time-domain unit has a length defined as T. c =1 / (Δf) max ·N f ), where Δf max =480·10 3 Hz, N f =4096, constant k=64. T C The values ​​of and k can also be defined as other values. L = 0, i.e., symbol #0, represents the first symbol within the first time interval, and its CP length is defined as (70κ·2 -μ +18κ)×T C L≠0 represents any other symbol (i.e., any one of symbol#1 to symbol#28) within the first time interval, excluding the first symbol, whose CP length is defined as (70κ·2). -μ )×T C The data portion length of all symbols within the first time interval is (2048k·2). -μ )×T C .

[0137] As shown in Figure 17, taking a 15kHz subcarrier spacing as an example, i.e. μ = 0, the length of the first time interval is 2ms; the CP length of the first symbol in the first time interval is about 2.86us, the CP length of the other symbols in the first time interval is about 2.28us, and the data part length of all symbols in the first time interval is about 66.67us.

[0138] In another example of the embodiments of this application, the first time interval is defined as 3×2. -μms, where μ corresponds to the subcarrier spacing as shown in Table 1. The first time interval contains 44 symbols, i.e., symbol #0 to symbol #43. The CP length of the first symbol in the first time interval is different from the CP lengths of all other symbols in the first time interval. In some instances, as shown in formula (5), where L is the symbol index in the first time interval, T... c The basic time-domain unit has a length defined as T. c =1 / (Δf) max ·N f , where Δf max =480·10 3 Hz, N f =4096, constant k=64. T C The values ​​of and k can also be defined as other values. L = 0, i.e., symbol #0, represents the first symbol within the first time interval, and its CP length is defined as (46κ·2 -μ +24κ)×T C L≠0 represents any other symbol (i.e., any one of symbol#1 to symbol#43) within the first time interval, excluding the first symbol, whose CP length is defined as (46κ·2). -μ )×T C The data portion length of all symbols within the first time interval is (2048k·2). -μ )×T C .

[0139] For example, taking a 15kHz subcarrier spacing, i.e. μ = 0, the length of the first time interval is 3ms; the CP length of the first symbol in the first time interval is about 2.28us, the CP length of the other symbols in the first time interval is about 1.5us, and the data part length of all symbols in the first time interval is about 66.67us.

[0140] In another example of the embodiments of this application, the first time interval is defined as 3×2. -μ ms, where the correspondence between μ and the subcarrier spacing is shown in Table 1. Within the first time interval, there are 44 symbols, i.e., symbol #0 to symbol #43. Within the first time interval, every 1.5 × 2 ms... -μThe CP length of the first symbol in ms (i.e., symbol #0 and symbol #22 within the first time interval) is different from the CP length of other symbols within the first time interval. In some instances, as shown in formula (6), for L = 0 or L = 22, i.e., symbol #0 or symbol #22 within the first time interval, its CP length is defined as (46κ·2 -μ +12κ)×T C For L≠0 and L≠22, its CP length is defined as (46κ·2 -μ )×T C The data portion length of all symbols within the first time interval is (2048k·2). -μ )×T C .

[0141] For example, taking a 15kHz subcarrier spacing, i.e. μ = 0, the length of the first time interval is 3ms; the CP length of the first symbol in the first time interval is about 2.28us, the CP length of the other symbols in the first time interval is about 1.5us, and the data part length of all symbols in the first time interval is about 66.67us.

[0142] In another example of the embodiments of this application, the first time interval is defined as 4×2. -μ ms, where the correspondence between μ and the subcarrier interval is shown in Table 1. In the first time interval, there are 59 symbols, namely symbol#0 to symbol#58. The CP length of the first symbol in the first time interval (i.e., symbol#0 in the first time interval) is different from the CP length of other symbols in the first time interval. In some instances, as shown in formula (7), for L=0, i.e., symbol#0 in the first time interval, its CP length is defined as (34κ·2 -μ +8κ)×T C For L≠0, its CP length is defined as (34κ·2 -μ )×T C The data portion length of all symbols within the first time interval is (2048k·2). -μ )×T C .

[0143] For example, taking a 15kHz subcarrier spacing, i.e. μ = 0, the length of the first time interval is 4ms; the CP length of the first symbol in the first time interval is about 1.37us, the CP length of the other symbols in the first time interval is about 1.11us, and the data part length of all symbols in the first time interval is about 66.67us.

[0144] In some implementations, the various CP configuration methods described above can be combined in any way. For example, more than one CP overhead can be time-division multiplexed to form a comprehensive time-domain pattern. As shown in Figure 18, taking 15kHz as an example, the symbols in the first 2ms are configured as a 29-symbol mode, and the symbols in the last 3ms are configured as a 44-symbol mode. The switching between different CP modes can be based on RRC signaling or MAC layer signaling configuration, or indicated by physical layer signaling, or fixedly defined in the protocol.

[0145] This embodiment provides a flexible way to reduce CP overhead, defining a variety of low CP overhead modes, which helps to improve data transmission efficiency in short-distance transmission.

[0146] This embodiment provides another flexible method for configuring cyclic prefixes. In an exemplary embodiment, for short-distance transmission, such as within decellularized cells, a low CP overhead mode is defined, where more resources are used for data transmission to improve spectral efficiency.

[0147] In some implementations, the CP overhead can be reduced by defining a longer data portion.

[0148] In one example, a time slot contains 16 symbols, and the reference SCS is defined as 16.5 kHz. Therefore, under the reference SCS, the length of each symbol is 1 / 16 = 0.0625 ms = 62.5 μs. The other subcarrier spacing can be obtained by scaling the reference SCS. Thus, the length of the data portion within a symbol is 1 / 16.5 = 0.0606 ms = 60.6 μs. The remaining CP portion has a length of 62.5 - 60.6 = 1.9 μs, and the overall CP overhead is approximately 3.04%.

[0149] In another example, a time slot contains 16 symbols, and the reference SCS is defined as 16.8 kHz. Therefore, under the reference SCS, the length of each symbol is 1 / 16 = 0.0625 ms = 62.5 μs. The other subcarrier spacing can be obtained by scaling the reference SCS. Thus, the length of the data portion within a symbol is 1 / 16.8 = 0.0595 ms = 59.5 μs. The remaining CP portion has a length of 62.5 - 59.5 = 3 μs, and the overall CP overhead is approximately 4.8%.

[0150] In another example, a time slot contains 16 symbols, and the reference SCS is defined as 17 kHz. Therefore, under the reference SCS, the length of each symbol is 1 / 16 = 0.0625 ms = 62.5 μs. The other subcarrier spacing can be obtained by scaling the reference SCS. Thus, the length of the data portion within a symbol is 1 / 17 = 0.0588 ms = 58.8 μs. The remaining CP portion has a length of 62.5 - 58.8 = 3.7 μs, and the overall CP overhead is approximately 5.92%.

[0151] In another example, a time slot contains 14 symbols, and the reference SCS is defined as 14.3 kHz. Other subcarrier spacing can be obtained by scaling the reference SCS. Therefore, under the reference SCS, the length of the first and seventh symbols in a time slot is approximately 71.9 μs, and the length of the other symbols in the slot (excluding the first and seventh symbols) is approximately 71.4 μs; thus, the length of the data portion within a symbol is 1 / 14.3 = 0.0699 ms = 69.9 μs. The remaining CP portion length for the first or seventh symbol is 71.9 - 69.9 = 2 μs, and for other symbols, the CP portion length is 1.5 μs, resulting in an overall CP overhead of approximately 2.25%.

[0152] In another example, a time slot contains 14 symbols, and the reference SCS is defined as 14.5 kHz. Other subcarrier spacing can be obtained by scaling the reference SCS. Therefore, under the reference SCS, the length of the first and seventh symbols in a time slot is approximately 71.9 μs, and the length of the other symbols in the slot (excluding the first and seventh symbols) is approximately 71.4 μs; thus, the length of the data portion within a symbol is 1 / 14.5 = 0.069 ms = 69 μs. The remaining CP portion length for the first or seventh symbol is 71.9 - 69 = 2.9 μs, and for other symbols, the CP portion length is 2.4 μs, resulting in an overall CP overhead of approximately 3.58%.

[0153] In another example, a time slot contains 14 symbols, and the reference SCS is defined as 14.8 kHz. Other subcarrier spacing can be obtained by scaling the reference SCS. Therefore, under the reference SCS, the length of the first and seventh symbols in a time slot is approximately 71.9 μs, and the length of the other symbols in the slot (excluding the first and seventh symbols) is approximately 71.4 μs; thus, the length of the data portion within a symbol is 1 / 14.8 = 0.0676 ms = 67.6 μs. The remaining CP portion length for the first or seventh symbol is 71.9 - 67.6 = 4.3 μs, and for other symbols, the CP portion length is 3.8 μs, resulting in an overall CP overhead of approximately 5.73%.

[0154] In some implementations, the various CP configuration methods described above can be combined in any way. For example, more than one CP overhead can be time-division multiplexed to form a comprehensive time-domain pattern. The switching between different CP modes can be configured based on RRC signaling or MAC layer signaling, indicated by physical layer signaling, or fixedly defined in the protocol.

[0155] This embodiment provides a flexible way to reduce CP overhead. By changing the subcarrier spacing, it defines a variety of low CP overhead modes, which helps to improve the efficiency of data transmission.
