[0019] The technical solutions in the present disclosure will be described clearly and completely below in combination with the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present disclosure.

[0020] It should be noted that in the present disclosure, the words "exemplary" or "for example" are used on the basis and in the sense of patent law to mean that specified circumstances (example embodiments) are exemplary and / or for purposes of illustration. Any embodiment or design scheme described by "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or having greater advantages than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" is intended to present related concepts in a concrete manner.

[0021] Hereinafter, the terms "first", "second", and the like are used only for the purpose of description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined by the terms "first", "second", and the like can be explicitly or implicitly included one or more of the features.

[0022] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this document is only used to describe the association relationship of the associated objects, which means that there can be three relationships. For example, A and / or B can mean: only A, A and B, only B. In addition, "at least one" means one or more, and "multiple" means two or more.

[0023] With the continuous progress of radio technology, a large number of various radio services have emerged. In addition to the cellular services between base stations and terminals, there are various communication services in local or personal range.

[0024] Typical communication systems, such as LTE (long term evolution) systems, NR (new radio) systems, short distance communication systems, WiFi (wireless fidelity) systems, Bluetooth systems, vehicle-to-everything systems, industrial internet systems, Starlink systems, and future communication systems, all need to consider system parameters, frame structures, and resource allocation.

[0025] Most of the above communication systems are based on OFDM (orthogonal frequency division multiplexing) modulation / demodulation. Here, several important parameters are involved, such as SCS (subcarrier spacing) △f, sampling rate or reference frequency f s , sampling interval or basic time unit Fourier transform / inverse Fourier transform point number Number of subcarriers N SCS , bandwidth BW, radio frame length or slot length T f, OFDM symbol number N symb , OFDM symbol duration T symb , cyclic prefix (CP) duration T CP (including normal cyclic prefix, extended cyclic prefix), switching interval duration T GAP (including switching interval under normal cyclic prefix, switching interval under extended cyclic prefix) and the like.

[0026] Exemplarily, the star alliance system is taken as an example for illustration. The system is given a subcarrier spacing △f = 480 kHz, a sampling rate f s = 30.72 MHz, a radio frame duration T f = 640 T s ≈ 20.83 μs, and a bandwidth BW = 20 MHz.

[0027] That is, the communication parameters in the communication system are set when the communication system is deployed, and the communication system works in the communication parameters set at the time of deployment during the subsequent operation of the communication system.

[0028] However, such a single fixed parameter is not conducive to the evolution of the communication system. Therefore, how to realize the flexible adjustment of the communication parameters, solve the problems of scaling system parameters, flexible frame structure, and resource allocation, has become a technical problem to be solved.

[0029] Based on this, in order to solve the above technical problems, the embodiment of the disclosure provides a communication parameter adjustment method. For a single fixed parameter communication system, one end node of a communication link sends information for adjusting the communication parameters to the other end node, the related parameters of the communication link can be modified to realize the dynamic adjustment of different communication parameters. Compared with the fixed communication parameters to realize the communication transmission between the two end nodes of the communication link, the embodiment of the disclosure can flexibly compatible with the evolution of the communication system of different communication parameters or the change of the scene demand, automatically modify the communication parameters to realize the flexible adjustment of the communication parameters, and solve the problems of scaling system parameters, flexible frame structure, and resource allocation.

[0030] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks (for example, 5th generation mobile communication technology Advanced (5G-A), 6th generation mobile communication technology (6G)) in the embodiments of the present disclosure can at least include a first communication node and a second communication node. It should be understood that in the present example, in the downlink, the first communication node can be a terminal side device (for example, including but not limited to a terminal), and the second communication node can be a network side device (for example, including but not limited to a base station). Of course, in the uplink, the first communication node can also be a network side device, and the second communication node can also be a terminal side device. In the communication between the two communication nodes, the first communication node and the second communication node can both be base stations or terminals. The first communication node and the second communication node can be referred to as the first node and the second node respectively.

[0031] Exemplarily, taking the first node as a terminal and the second node as a base station as an example, a communication system according to an embodiment of the present disclosure is shown in FIG. 1. The communication system includes a base station 101 and a terminal 102. The terminal 102 can be one or more, and the number is not limited.

[0032] The base station 101 can send first information for adjusting a parameter value of a communication parameter to the terminal 102. Then, the terminal 102 can adjust a first parameter value corresponding to the communication parameter in the terminal 102 to a second parameter value in response to receiving the first information from the base station 101.

[0033] It should be noted that in the embodiments of the present disclosure, the communication parameter for adjustment can be a frequency domain parameter or a time domain parameter.

The time domain parameter can include at least one of the following: switching interval length, cyclic prefix length, OFDM symbol length, OFDM symbol number, resource attribute of OFDM symbol, wireless frame length.

[0035] It should be noted that the base station (BS) can be a base station or an evolved node B (eNB or eNodeB) in LTE or long term evolution advanced (LTE-A), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RISs), routers, relays, TRPs (transmission and reception points), WIFI devices, and various network side devices.

[0036] The terminal can be a device with wireless transceiving function. The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiving function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal can also be referred to as a user, a user equipment (UE), an access terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE apparatus, etc. The embodiments of the present disclosure do not limit this.

[0037] In some embodiments, the first node can be any of the following: a relay node, an auxiliary node, a terminal node.

The relay node and the auxiliary node can both be integrated access and backhaul (IAB) nodes, repeater nodes with relay functions. The terminal node can be a user equipment, an internet of things (IoT) device.

[0039] It should be noted that in the embodiments of the present disclosure, the first node and the second node can have various combinations. For example, the first node is a relay node, and the second node is a combination of network nodes. For another example, the first node is a terminal node, and the second node is a combination of auxiliary nodes. For another example, the first node is a relay node, and the second node is also a relay node.

[0040] It should be noted that FIG. 1 is only an exemplary framework diagram, the number of devices included in FIG. 1, and the names of various devices are not limited, and in addition to the devices shown in FIG. 1, the communication system can also include other devices, such as core network devices.

[0041] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0042] FIG. 2 shows a flow diagram of a communication parameter adjustment method. As shown in FIG. 2, the communication parameter adjustment method is applied to a first node, and includes S201 and S202.

[0043] In S201, the first node receives first information sent by a second node.

[0044] The first information is used to indicate a parameter value of an adjusted communication parameter.

[0045] It should be noted that in the embodiments of the present disclosure, the communication parameter can be a frequency domain parameter, or the communication parameter can be a time domain parameter.

[0046] In some embodiments, in the case where the communication parameter is a frequency domain parameter, the frequency domain parameter can include at least one of the following: subcarrier spacing, subcarrier number, bandwidth.

[0047] In some embodiments, when the communication parameter is a time domain parameter, the time domain parameter can include at least one of: a switching interval length, a cyclic prefix length, an OFDM symbol length, a number of OFDM symbols, a resource attribute of an OFDM symbol, and a radio frame length.

[0048] It should be noted that the radio frame structure includes a series of subframes, which are arranged for uplink or downlink transmission, or a mixture of both. In a time division duplex (TDD) mode, the radio frame is divided into fixed uplink time slots, downlink time slots, and a guard interval (GAP). The resource attribute of the OFDM symbol is used to represent the identity of the subframe in the radio frame, such as uplink (U) symbols, downlink (D) symbols, and GAP symbols.

[0049] That is, by embodying different types of communication parameters, it is illustrated that the embodiments of the present disclosure can adjust different types of frequency domain parameters and time domain parameters to expand the application scenarios of the embodiments of the present disclosure.

[0050] In S202, the first node adjusts the communication parameter from the first parameter value to the second parameter value.

[0051] The first parameter value is the current parameter value of the first node's own communication parameter when the first node receives the first information.

[0052] As an implementation manner, the first node can store the second parameter value. The first node can adjust the first parameter value to the second parameter value in response to receiving the first information from the second node.

[0053] It should be noted that the embodiments of the present disclosure do not limit the size relationship between the first parameter value and the second parameter value. For example, the second parameter value can be greater than the first parameter value. For another example, the second parameter value can be less than the first parameter value. For another example, the second parameter value can be equal to the first parameter value.

[0054] That is, the first node can update the system parameter of itself based on the stored preset parameter value, and then realize flexible adjustment of the communication parameter. In this way, by illustrating the size relationship between the communication parameter before adjustment and the communication parameter after adjustment, it is illustrated that the embodiments of the present disclosure can realize three adjustment modes of enlargement, reduction, or keeping unchanged, and embody the flexibility of communication parameter adjustment.

[0055] As another implementation manner, the first information can include a parameter value of an adjustment parameter. The first node can determine the second parameter value based on the parameter value of the adjustment parameter and the first parameter value.

[0056] That is, the second parameter value is determined by the first parameter value and the parameter value of the adjustment parameter. In this way, the scaled adjustment of the communication parameter is achieved by multiplying the communication parameter before adjustment by the adjustment parameter used to represent the scaling degree to obtain the communication parameter after adjustment,

[0057] In some embodiments, the first node can obtain the second parameter value by calculating the product between the first parameter value and the parameter value of the adjustment parameter.

[0058] In the embodiments of the present disclosure, the adjustment parameter can include a first adjustment parameter k and a second adjustment parameter b μ , and the values of k and b μ satisfy any of the following conditions:

[0059] (1) k is a rational number greater than or equal to 1, b is an integer greater than 1, and μ is an integer greater than or equal to 0;

[0060] (2) k is a rational number between 0 and 1, b is an integer greater than 1, and μ is an integer less than or equal to 0;

[0061] (3) k is equal to 1, b is equal to 1, and μ is any real number;

[0062] (4) k is equal to 1, μ is equal to 0, and b is a non-zero real number.

[0063] That is, the first node can perform scaling processing on its system parameters based on the value changes of different adjustment parameters in the first information, thereby achieving flexible adjustment of the communication parameter. In this way, by limiting the values of different components of the adjustment parameter used to represent the scaling degree, a plurality of adjustment parameters of different scaling degrees can be determined to ensure flexible scaling of the communication parameter.

[0064] The following takes different communication parameters as examples to introduce the adjustment of the parameter value of the communication parameter.

[0065] Example 1

[0066] If the initial or given or reference subcarrier spacing is denoted as △f ini (that is, the first parameter value of the subcarrier spacing), then:

[0067] The subcarrier spacing is reduced, △f = △f ini · k·b μ , where △f is the second parameter value of the subcarrier spacing, k is a rational number in the interval (0, 1], b is an integer in the interval [1, +∞), and μ is an integer in the interval (-∞, 0];

[0068] The subcarrier spacing is enlarged, △f = △f ini · k·b μwhere k is a rational number in the interval [1, +∞), b is an integer in the interval [1, +∞), and μ is an integer in the interval [0, +∞).

[0069] Without reducing (or not amplifying) the subcarrier spacing (i.e., keeping it unchanged), Δf = Δf ini · k · b μ where k = 1, b = 1, and μ is any real number, or k = 1, μ = 0, and b is a non-zero real number.

[0070] In some embodiments, the following examples are illustrated with b = 2.

[0071] Example 2

[0072] If the initial or given or reference number of subcarriers is denoted by N SCS,ini (i.e., the first parameter value of the number of subcarriers), then:

[0073] Reducing the number of subcarriers, N SCS = N SCS,ini · k · 2 μ where N SCS is the second parameter value of the number of subcarriers, k is a rational number in the interval (0, 1], and μ is an integer in the interval (-∞, 0];

[0074] Amplifying the number of subcarriers, N SCS = N SCS,ini · k · 2 μ where k is a rational number in the interval [1, +∞), and μ is an integer in the interval [0, +∞).

[0075] Without reducing (or not amplifying) the number of subcarriers, N SCS = N SCS,ini · k · 2 μ where k = 1 and μ = 0.

[0076] Example 3

[0077] If the initial or given or reference bandwidth is denoted by BW ini (i.e., the first parameter value of the bandwidth), then:

[0078] Reducing the bandwidth, BW = BW ini · k · 2 μ where BW is the second parameter value of the bandwidth, k is a rational number in the interval (0, 1], and μ is an integer in the interval (-∞, 0];

[0079] Amplifying the bandwidth, BW = BW ini · k · 2 μ where k is a rational number in the interval [1, +∞), and μ is an integer in the interval [0, +∞).

[0080] not reducing (or not amplifying) the bandwidth, BW = BW ini · k · 2 μ where k = 1, μ = 0.

[0081] Example 4

[0082] If an initial or given or reference switching interval duration is denoted by T GAP,ini (i.e. the first parameter value of the switching interval duration), then:

[0083] reducing the switching interval duration, T GAP = T GAP,ini · k · 2 μ where T GAP is the second parameter value of the switching interval duration, k is a rational number in the interval (0, 1], and μ is an integer in the interval (-∞, 0];

[0084] amplifying the switching interval duration, T GAP = T GAP,ini · k · 2 μ where k is a rational number in the interval [1, +∞), and μ is an integer in the interval [0, +∞);

[0085] not reducing (or not amplifying) the switching interval duration, T GAP = T GAP,ini · k · 2 μ where k = 1, μ = 0.

[0086] Example 5

[0087] If an initial or given or reference cyclic prefix duration is denoted by T CP,ini (i.e. the first parameter value of the cyclic prefix duration), then:

[0088] reducing the cyclic prefix duration, T CP = T CP,ini · k · 2 μ where T CP is the second parameter value of the cyclic prefix duration, k is a rational number in the interval (0, 1], and μ is an integer in the interval (-∞, 0];

[0089] amplifying the cyclic prefix duration, T CP = T CP,ini · k · 2 μ where k is a rational number in the interval [1, +∞), and μ is an integer in the interval [0, +∞);

[0090] not reducing (or not amplifying) the cyclic prefix duration, T CP = T CP,ini · k · 2 μ, where k = 1 and μ = 0.

[0091] Example 6

[0092] If the initial, given, or reference OFDM symbol duration is denoted as T symb,ini (i.e., the first parameter value of OFDM symbol duration), then:

[0093] Reduce OFDM symbol duration, T symb =T symb,ini ·k·2 μ , among which, T symb The second parameter value for the OFDM symbol duration is k, which is a rational number in the interval (0,1], and μ, which is an integer in the interval (-∞,0].

[0094] Increase OFDM symbol duration, T symb =T symb,ini ·k·2 μ , where k is a rational number in the interval [1,+∞), and μ is an integer in the interval [0,+∞);

[0095] OFDM symbol duration without reduction (or enlargement), T symb =T symb,ini ·k·2 μ , where k = 1 and μ = 0.

[0096] Example 7

[0097] Let N be the initial, given, or reference number of OFDM symbols. symb,ini (i.e., the first parameter value of the number of OFDM symbols), then:

[0098] Reduce the number of OFDM symbols, N symb =N symb,ini ·k·2 μ , where N symb The second parameter value is the number of OFDM symbols, k is a rational number in the interval (0,1], and μ is an integer in the interval (-∞,0].

[0099] Increase the number of OFDM symbols, N symb =N symb,ini ·k·2 μ , where k is a rational number in the interval [1,+∞), and μ is an integer in the interval [0,+∞);

[0100] The number of OFDM symbols without scaling down (or scaling up), N symb =N symb,ini ·k·2 μ , where k = 1 and μ = 0.

[0101] Example 8

[0102] Let the initial or given or reference wireless frame duration be denoted as T f,ini (i.e., the first parameter value of the wireless frame duration), then:

[0103] The wireless frame duration T f = T f,ini · k · 2 μ , where T f is the second parameter value of the wireless frame duration, k is a rational number in the interval (0, 1], and μ is an integer in the interval (-∞, 0];

[0104] The wireless frame duration T f = T f,ini · k · 2 μ , where k is a rational number in the interval [1, +∞), and μ is an integer in the interval [0, +∞);

[0105] The wireless frame duration T f = T f,ini · k · 2 μ , where k = 1 and μ = 0.

[0106] It should be noted that for the adjustment of the resource attribute of the OFDM symbol, the first node can store a plurality of preset parameter values and a plurality of preset resource attributes corresponding relationship. After adjusting the first parameter value to the second parameter value, the first node can determine the parameter value in the plurality of preset parameter values which is same as the second parameter value, and take the preset resource attribute corresponding to the parameter value in the plurality of preset parameter values which is same as the second parameter value as the target resource attribute, and adjust the OFDM symbol to the target resource attribute.

[0107] Exemplarily, the resource attribute of the OFDM symbol includes U symbol, D symbol and GAP symbol. The parameter value corresponding to the U symbol is an integer in the interval [2, 5], the parameter value corresponding to the D symbol is an integer in the interval [0, 1], and the parameter value corresponding to the GAP symbol is an integer in the interval [6, 7]. If the parameter value corresponding to the resource attribute of the OFDM symbol is adjusted from 3 (the first parameter value) to 6 (the second parameter value), it is equivalent to adjusting the U symbol to the GAP symbol.

[0108] It can be understood that for a communication system with a single fixed parameter, the information of adjusting the communication parameter is sent by one end node of the communication link to the other end node, and the related parameters of the communication link can be modified to realize dynamic adjustment of different communication parameters. Compared with the communication transmission between the two end nodes of the communication link with fixed communication parameters, the embodiments of the present disclosure can flexibly adapt to the evolution of the communication system with different communication parameters or the change of the scene demand, automatically modify the communication parameters to realize flexible adjustment of the communication parameters, and solve the problems of scaling system parameters, flexible frame structure and resource allocation.

[0109] It should be noted that in order to support more flexible coverage, the adjustment of the cyclic prefix length parameter can be adjusted in combination with the actual operation of the communication system in addition to the adjustment based on the scaling or scaling of the adjustment parameter.

[0110] In some embodiments, in the case that the communication parameter indicated in the first information is the cyclic prefix length, the first information can further include any of the following: (1) a second parameter value; (2) a parameter value of a reference parameter used to determine the second parameter value.

[0111] The reference parameter includes: a wireless frame length, a number of OFDM symbols, a number of switching intervals, and a switching interval length.

[0112] As an implementation manner, if the first information includes the second parameter value, the first node can adjust its own communication parameter from the first parameter value to the second parameter value based on the second parameter value in the first information after receiving the first information.

[0113] That is, the second node can directly indicate to adjust the cyclic prefix length to a certain parameter value, and the first node can adjust its own cyclic prefix length to the parameter value indicated by the second node after receiving the first information, which enriches the parameter adjustment strategy of the cyclic prefix length.

[0114] As another implementation manner, if the first information includes the parameter value of the reference parameter, the first node can perform mathematical operation on the wireless frame length, the number of OFDM symbols, the number of switching intervals, and the switching interval length in the first information to determine the second parameter value after receiving the first information, and then adjust its own communication parameter from the first parameter value to the second parameter value.

[0115] In some embodiments, the parameter value of the reference parameter includes: a parameter value T f of the wireless frame length, a parameter value T GAP of the switching interval length, a parameter value N GAP of the number of switching intervals, and a parameter value N symb of the number of OFDM symbols. The second parameter value is determined based on T f , T GAP, N GAP , N symb The relationship between the first parameter value and the second parameter value satisfies any one of the following conditions:

[0116] The second parameter value is equal to the upward rounding of

[0117] The second parameter value is equal to the downward rounding of

[0118] The second parameter value is equal to the rounding of

[0119] The second parameter value is equal to the rounding of

[0120] That is, the second node can inform the first node of the used wireless frame length, the OFDM symbol number, the switching interval number and the switching interval length as the reference parameter for the parameter adjustment of the cyclic prefix length of the first node itself, so that the first node can perform the parameter adjustment of the cyclic prefix length based on the real-time communication environment of the second node, and the parameter adjustment strategy of the cyclic prefix length is enriched.

[0121] Exemplarily, the parameter value of the adjusted cyclic prefix length (i.e., the second parameter value) is determined by T f , T GAP , N GAP , N symb , and includes:

[0122] , or

[0123] , or

[0124] , or

[0125] N GAP represents that N GAP T GAP s are included in a wireless frame, and N GAP ≥ 0; ceil(·) represents upward rounding of the content in the parentheses; floor(·) represents downward rounding of the content in the parentheses; and round(·) represents rounding of the content in the parentheses.

[0126] It should be noted that in the case of a communication system being a Starlink system, in order to support G / T flexible configuration and G / T multiple switching within a wireless frame, the allocation adjustment of the time domain resource (i.e., the adjustment of the resource attribute of the OFDM symbol) can also be realized by other ways.

[0127] ​​​In some embodiments, in the case that the communication parameter indicated in the first information is a resource attribute of an OFDM symbol, the first information can be used to indicate at least one of the following:

[0128] (1) resetting the symbol of each radio frame to at least one of the following: a G symbol, a T symbol, an H symbol, an R symbol, and a GAP;

[0129] (2) configuring the symbol of each radio frame to at least one of the following: a G symbol, a T symbol, an H symbol, an R symbol, and a GAP;

[0130] (3) configuring the symbol of a radio frame in each radio frame set to at least one of the following: a G symbol, a T symbol, an H symbol, an R symbol, and a GAP, configuring a used or available radio frame set, and configuring a radio frame set repetition period;

[0131] (4) configuring the symbol of a radio frame in each superframe to at least one of the following: a G symbol, a T symbol, an H symbol, an R symbol, and a GAP, configuring a used or available superframe, and configuring a superframe repetition period.

[0132] The G symbol represents a symbol for G-link transmission, the T symbol represents a symbol for T-link transmission, the H symbol represents a sub-band full-duplex symbol or a full-duplex symbol for G-link transmission and T-link transmission, the R symbol represents a symbol for flexible reconfiguration or a forward-backward compatible reserved symbol, and the GAP represents a switching interval between G-link transmission and T-link transmission or a switching interval between T-link transmission and G-link transmission. The G-link represents a communication link from a gateway node (G node, i.e., a second node) to a terminal node (T node, i.e., a first node), and the T-link represents a communication link from the T node to the G node. Each radio frame set includes a variable number of radio frames (i.e., the radio frame set is of variable duration), and each superframe includes a fixed number of radio frames (i.e., the superframe is of fixed duration).

[0133] It should be noted that in the embodiments of the present disclosure, the resetting indicated by the first information can be reconfiguration, i.e., the optional range of configuration can be configured by modulation. The configuration indicated by the first information is performed in the case that the optional range is unchanged.

[0134] Exemplarily, the current optional range A of the symbol of a radio frame in the first node includes a symbol A, a symbol B, and a symbol C. If the first information indicates resetting the symbol of the radio frame, the first information can include a new optional range B: the symbol A, the symbol B, the symbol C, and a symbol D, and the first node can adjust the symbol of the radio frame based on the symbols in the optional range B. If the first information indicates configuring the symbol of the radio frame, the first node can adjust the symbol of the radio frame based on the symbols in the original optional range A.

[0135] It can be understood that, in the process of parameter adjustment on the resource attribute of the OFDM symbol, the switching of the resource attribute is performed by using the symbol of a single radio frame, the symbol of a plurality of radio frames of a radio frame set, the use or available attribute, the repetition period, and the symbol of a plurality of radio frames of a superframe, the available or use attribute, and the repetition period, so that parameter adjustment of different granularities is embodied, and the adjustment efficiency of the communication parameter is improved.

[0136] It should be noted that, in order to adapt to flexible bandwidth, the allocation adjustment of the frequency domain resource (such as the number of subcarrier groups, the size of a subcarrier group, a subcarrier index, and the like) can also be implemented in other manners.

[0137] In some embodiments, in the case that the communication parameter indicated in the first information is the bandwidth, the first information can further include at least one of the following:

[0138] (1) the number of subcarrier groups within the bandwidth or the subband, and a first indication of the number of subcarriers in each subcarrier group and the subcarrier index of each subcarrier group based on a predefined rule;

[0139] (2) the number of subcarriers in the subcarrier group within the bandwidth or the subband, and a second indication of the number of subcarrier groups and the subcarrier index of each subcarrier group based on a predefined rule;

[0140] (3) the used or available subband, subcarrier group, and subcarrier.

[0141] That is, in the case that the communication parameter indicated in the first information is the bandwidth, the first node can not only adjust the parameter value of the bandwidth, but also synchronously adjust the number of subcarrier groups within the bandwidth, the size of the subcarrier group (that is, the number of subcarriers in the subcarrier group), and the subcarrier index.

[0142] In the embodiments of the present disclosure, the predefined rule can include at least one of the following:

[0143] (1) the subband, subcarrier group, and subcarrier used for G-link transmission;

[0144] (2) the subband, subcarrier group, and subcarrier used for T-link transmission;

[0145] (3) the subcarrier group in a continuous manner;

[0146] (4) the subcarrier group in a discrete manner;

[0147] (5) whether the subcarrier group has a direct current (DC) subcarrier;

[0148] (6) whether the subcarrier group has a subcarrier used for transmitting non-user data;

[0149] (7) whether a subcarrier group has a subcarrier for transmitting overhead information;

[0150] (8) whether a subcarrier group has a virtual subcarrier;

[0151] (9) whether a subcarrier group has a reserved / protection subcarrier.

[0152] The subcarriers for transmitting non-user data can include reference signal (RS) subcarriers and overhead subcarriers (O-SCs) (such as subcarriers for transmitting overhead information). The virtual subcarriers are subcarriers for balancing the number of subcarriers in each subcarrier group.

[0153] Exemplarily, the plurality of subcarriers are sequentially: subcarrier A, subcarrier B, subcarrier C, subcarrier D, and subcarrier E. The subcarrier B is a direct current subcarrier, and the subcarrier E is an RS subcarrier. If the predefined rule includes: a subcarrier group does not have a direct current subcarrier, and a subcarrier group has an RS subcarrier, the plurality of subcarriers can correspond to two subcarrier groups (subcarrier group A and subcarrier group B). The subcarrier group A includes: the subcarrier A and the subcarrier C, and the subcarrier group B includes: the subcarrier D and the subcarrier E.

[0154] It can be understood that, in the process of adjusting the bandwidth, the number of subcarrier groups, the size of subcarrier groups, the index of subcarriers, and the parameters of the use or availability of subbands, subcarrier groups, and subcarriers are extended to achieve flexible allocation of frequency domain resources under different bandwidths.

[0155] It should be noted that, in the case of adjustment of the subcarrier spacing, the frequency domain / time domain resources corresponding to different subcarriers also need to be aligned.

[0156] In some embodiments, in the case that the communication parameter indicated in the first information is the subcarrier spacing, the first information can further include a third indication of aligning the communication resources based on the ratio of different subcarrier spacings.

[0157] In the embodiments of the present disclosure, the first node can determine the numerator m and the denominator n in the ratio of the first spacing to the second spacing in response to the third indication, and align the communication resources corresponding to the first spacing and the second spacing based on m and n. The first spacing and the second spacing are any spacings in all subcarrier spacings.

[0158] It should be noted that the communication resources can be time domain resources, or the communication resources can be frequency domain resources.

[0159] As an implementation form, if the communication resource is a frequency domain resource, the process of aligning the communication resources corresponding to the first interval and the second interval based on m and n by the first node can include at least one of the following:

[0160] (1) the center of the subcarriers corresponding to the first interval is aligned with the center of the subcarriers corresponding to the second interval in the frequency domain;

[0161] (2) the n subcarriers corresponding to the first interval are aligned with the m subcarriers corresponding to the second interval in the frequency domain;

[0162] (3) the subcarrier group corresponding to the first interval is aligned with the subcarrier group corresponding to the second interval in the frequency domain.

[0163] As another implementation form, if the communication resource is a time domain resource, the process of aligning the communication resources corresponding to the first interval and the second interval based on m and n by the first node can include at least one of the following:

[0164] (1) the m OFDM symbols corresponding to the first interval are aligned with the n OFDM symbols corresponding to the second interval in the time domain;

[0165] (2) the radio frame corresponding to the first interval is aligned with the radio frame corresponding to the second interval in the time domain;

[0166] (3) the superframe corresponding to the first interval is aligned with the superframe corresponding to the second interval in the time domain.

[0167] It should be noted that for the alignment process of the above different communication resources, reference can be made to the alignment of the frequency domain / time domain resources in the design of the communication system in the related art, which will not be described here.

[0168] It can be understood that in the process of adjusting the subcarrier interval, the time domain resource or the frequency domain resource corresponding to different subcarrier intervals is aligned by expanding the ratio based on the adjusted different subcarrier intervals, so as to ensure efficient and orderly use of the entire frequency spectrum, and to realize efficient transmission and reception of signals.

[0169] The embodiment of the disclosure further provides a communication parameter adjustment method applied to a second node. As shown in FIG. 3, the communication parameter adjustment method can include: S301, the second node sends first information to a first node.

[0170] In the embodiment of the disclosure, the second node can generate corresponding first information in response to the change of the parameter value of the communication parameter of the second node, and send the first information to the first node.

[0171] For example, if the parameter value of the subcarrier interval of the second node changes, the second node can indicate to the first node to adjust the parameter value of the subcarrier interval.

[0172] That is, in the case that the parameter value of the communication parameter of one communication node in the communication system is changed, the parameter value of the communication parameter of the opposite communication node also needs to be changed synchronously, so that the parameter values of the communication parameters used by the communication nodes at both ends of the communication link are the same, and the communication link between different communication nodes in the communication system can be ensured to operate normally.

[0173] It should be noted that the present embodiment does not limit the change mode of the parameter value of the communication parameter of the second node itself. For example, the second node can update the parameter value of the communication parameter of itself based on the parameter value input by the user. For another example, the second node can change the parameter value of the communication parameter of itself to a preset value based on a preset period. For another example, the second node can update the parameter value of the communication parameter of itself in response to information sent by other nodes (such as upstream nodes of the second node) for indicating adjustment of the parameter value of the communication parameter.

[0174] In some embodiments, in the case that the communication parameter is a subcarrier spacing, the first information can further include a third indication of communication resource alignment based on a ratio of different subcarrier spacings. The communication resource can be a time domain resource, or the communication resource can be a frequency domain resource.

[0175] As an implementation manner, if the communication resource is a frequency domain resource, the alignment of the frequency domain resource corresponding to the third indication can include at least one of the following:

[0176] (1) the subcarrier centers corresponding to different subcarrier spacings are aligned in the frequency domain;

[0177] (2) a plurality of subcarriers corresponding to different subcarrier spacings are aligned in the frequency domain;

[0178] (3) a subcarrier group corresponding to different subcarrier spacings is aligned in the frequency domain.

[0179] As another implementation manner, if the communication resource is a time domain resource, the alignment of the time domain resource corresponding to the third indication can include at least one of the following:

[0180] (1) a plurality of OFDM symbols corresponding to different subcarrier spacings are aligned in the time domain;

[0181] (2) radio frames corresponding to different subcarrier spacings are aligned in the time domain;

[0182] (3) superframes corresponding to different subcarrier spacings are aligned in the time domain.
