Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a frequency band determination method, apparatus, device, and readable storage medium. Background Art

[0002] For a large carrier bandwidth, the bandwidth required by a terminal is often limited. If a terminal (e.g., user equipment (UE)) were required to perform real-time monitoring and maintenance of the full bandwidth, this would pose a significant challenge to terminal energy consumption. Therefore, the concept of bandwidth part (BWP) was proposed to address this issue of varying bandwidth requirements. The BWP concept allocates a portion of bandwidth within a large carrier for UE access and data transmission. The UE only needs to operate within this portion of the bandwidth allocated by the system. For example, when a UE with a bandwidth of 100 Mbps accesses a 200 Mbps cell, the base station will allocate a 100 Mbps BWP from the full 200 Mbps bandwidth for the UE to use.

[0003] Once a New Radio (NR) cell is successfully configured and a UE accesses the network, the number of BWPs, subcarrier spacing, and cyclic prefix are fixed. Of the multiple BWPs determined by the base station, a UE can only activate one at a time. This means the UE can only operate on one BWP at a time, and the bandwidth used by the UE cannot exceed the bandwidth range of this BWP, resulting in low resource utilization.

[0083] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0084] The term "comprise," "comprising," and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements need not be limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims to indicate at least one of the connected items, such as A and / or B, indicates that A alone, B alone, and both A and B are included.

[0085] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0086] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, although these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0087] Current frequency band determination schemes, based on the assumption that channel losses across different frequency bands are essentially the same, can directly use bandwidth as a means of determining the frequency band. However, in actual communications, due to the frequency response characteristics of transceiver components, the response information of some communication systems exhibits a correlation with frequency. Since response information varies across frequencies, if bandwidth is still used to determine the frequency band, two BWPs with the same bandwidth may have different communication capabilities. Existing base stations and terminals fail to account for this fact.

[0088] Furthermore, existing solutions only allow for one modulation and coding scheme (MCS) and one frequency domain resource allocation (FDRA) when mobilizing resources within a specific BWP. When the communication performance of different carriers within the same BWP varies significantly, and the required communication rate is high, prioritizing frequency filtering will result in insufficient carriers for communication. If the required communication rate is prioritized, information transmitted on some carriers will experience high bit errors. Furthermore, only one BWP can be used at a time, making this frequency band determination method incapable of high-capacity communication by UEs, and resulting in low resource utilization within the BWP.

[0089] For example, the received signal-to-noise ratio of an orthogonal frequency division multiplexing (OFDM) wireless optical communication system based on a light emitting diode (LED) varies linearly with the frequency range, such as Figure 1 As shown in the figure, the receiver signal-to-noise ratio (SNR) decreases with increasing subcarrier frequency, and the corresponding relationship is generally linear. Frequency band resources can be determined based on the SNR change, ensuring consistent SNR within the same frequency band. When activating resources, a single MCS is configured, allowing the UE to utilize all resources within the frequency band. This also allows the UE to activate two frequency band resources simultaneously, improving configuration flexibility.

[0090] See also Figure 2, showing a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 21 and a network-side device 22. The terminal 21 can also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 21 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (Vehicle User Equipment, VUE), a pedestrian terminal (Pedestrian User Equipment, PUE) and other terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 21 is not limited in the embodiment of the present application.

[0091] The network side device 22 can be a base station or a core network, where the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a TRP or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0120] Optionally, the first information is directly acquired by the transmitting end, or received by the transmitting end from the receiving end, or acquired by the transmitting end according to characteristics of a calibration module or a transmitting device of the transmitting end.

[0121] In this way, the frequency band is determined based on the correspondence between the threshold of the first information and the frequency band position. The entire frequency band can be scheduled using the same scheduling information, thereby improving resource utilization.

[0132] In this way, the transmitting end can notify the receiving end of the frequency band determination indication information (frequency band number), or the receiving end determines the frequency band to indicate to the receiving end according to the frequency band determination parameter, thereby saving the signaling overhead of the frequency band determination indication information.

[0133] In one embodiment of the present application, the step of indicating the MCS of the frequency band within the range of the MCS table corresponding to each frequency band in the at least one frequency band includes:

[0134] A new MCS table is determined based on the MCS index range of each frequency band determined by the CQI on each frequency band, and the new MCS table is sent to the receiving end; alternatively, the maximum and minimum values in the value range of the MCS index are sent to the receiving end, and the receiving end obtains a new MCS table based on the maximum and minimum values in the value range of the MCS index.

[0147] See also Figure 4 , an embodiment of the present application provides a frequency band determination method, the execution subject of the method can be a receiving end, and the specific steps include: step 401.

[0148] Step 401: Obtain at least one frequency band indicated by a transmitting end and an MCS table corresponding to each frequency band, wherein each frequency band includes at least one sub-band, first information corresponding to the sub-band satisfies a first constraint condition, and each sub-band is configured with an MCS table.

[0153] In one embodiment of the present application, the method further includes:

[0154] Parameters required for frequency band determination are received from the transmitting end, and / or frequency band determination indication information is received from the transmitting end, wherein the parameters are used by the receiving end to implement frequency band determination, and the frequency band determination indication information is used by the receiving end to determine the frequency band to be used.

[0155] In the embodiment of the present application, the frequency band indicated by the transmitting end to the receiving end corresponds to the first information, so that resources within the frequency band can all be called using the same scheduling information, thereby improving resource utilization.

[0156] An implementation of the present application is described below in conjunction with steps 1 to 4.

[0157] Step 1: The transmitting end obtains the frequency band position (or carrier frequency) and its corresponding first information.

[0158] The first information may be directly acquired by the sending end, or may be fed back to the sending end by the receiving end.

[0159] The first information may be fed back by the receiving end to the transmitting end, such as SNR, SINR, channel response, CQI, RSRP, RSRQ, RSSI, etc.;

[0160] Alternatively, the first information may also be obtained by the transmitting end according to characteristics of a transmitting end calibration module or a transmitting device.

[0161] Step 2: The transmitting end determines the frequency band according to the threshold of the first information and the corresponding relationship between the frequency band position and the first information.

[0162] Method 1: The transmitting end directly determines the threshold of the first information based on an algorithm or its own experience; after the threshold of the first information is determined, the frequency band is determined according to the threshold of the first information; the transmitting end specifies the frequency band to be used for the receiving end based on the capability information reported by the receiving end.

[0163] Optionally, a frequency band determination granularity (minimum divisible unit) may be determined, and the frequency band determination granularity and a threshold of the first information are comprehensively determined to ensure that the signaling overhead of the frequency band determination indication information is not excessive;

[0164] Optionally, a maximum frequency band width may be determined to avoid a frequency band interval that is too large when determined solely by using a threshold of the first information, so that the receiving end cannot use the frequency band.

[0165] Method 2: The transmitting end determines the fluctuation range of the first information within a single frequency band based on an algorithm or its own experience; the transmitting end obtains the capability information of the receiving end; and the transmitting end determines the frequency band for the receiving end based on the fluctuation range of the first information and the capability information of the receiving end.

[0166] In this step, the frequency band determination rule may require the continuity of the frequency band, that is, a frequency band can be a continuous set of frequency resources with the first information in the same interval, or a discontinuous set of frequency resources with the first information in the same interval.

[0167] Optionally, the receiving end capability information includes: a maximum receiving bandwidth and / or a first capability of the receiving end. The first capability may be the number of MCSs that can be decoded by the receiving end in one transmission opportunity.

[0168] Step 3: The transmitter allocates frequency bandwidth resources to the receiver.

[0169] Method 1: The transmitting end may notify the receiving end of the determined frequency band determination indication information (such as the number of frequency bands and the frequency band position);

[0170] Mode 2: The transmitting end may send the parameters required for frequency band determination (including the threshold range of the first information, the frequency band determination granularity, the maximum frequency band width, etc.) to the receiving end. The receiving end uses the frequency band determination parameters to perform frequency band determination (see the examples in the embodiment for details). The transmitting end sends frequency band indication information (such as the frequency band number) to the receiving end;

[0171] Mode 3: The transmitting end sends the frequency band determination parameters (including the threshold range of the first information, the frequency band determination granularity, the maximum frequency band width, etc.) to the receiving end. The receiving end uses the frequency band determination parameters to determine the frequency band (see the examples in the embodiment for details). The determined frequency band is unique and does not require a frequency band indication.

[0172] Step 4: The transmitting end or the receiving end confirms the MCS table corresponding to the frequency band used.

[0173] 1) The transmitter sends a CQI measurement command. Upon receiving the measurement command, the receiver performs a CQI measurement and reports the CQI after a certain period of time (e.g., 3ms). Based on the CQI reported by the receiver, the transmitter can determine the value range of the MCS index corresponding to the Reference CQI index from the MCS table (as shown in Table 1. The transmitter can map different MCS index ranges to CQIs based on its own experience). The transmitter can re-form an MCS table based on the value range of the MCS index corresponding to the Reference CQI index and send it to the receiver. Alternatively, the transmitter can send the maximum and minimum MCS index values to the receiver, and the receiver can obtain a new MCS table based on the maximum and minimum MCS index values.

[0174] 2) The transmitting end sends an MCS value range reporting instruction. After receiving the instruction, the receiving end performs CQI measurement and determines the maximum and minimum MCS indexes in the MCS Table based on the measured Reference CQI index. After a certain period of time (such as 3ms) after receiving the instruction, the receiving end reports the maximum and minimum MCS indexes.

[0175] a) The sender directly determines the MCS table range based on the maximum and minimum values of the MCS index reported by the receiver, and indicates the MCS index accordingly.

[0176] b) The sender uses the maximum and minimum values of the MCS index reported by the receiver as a reference to determine the value range of an MCStable, and sends the maximum and minimum values of the MCS Index to the receiver. The receiver obtains a new MCS Table based on the values.

[0179]

[0180] The transmitting end sends frequency band resource indication information, indicating the MCS instruction corresponding to each frequency band;

[0181] When the receiving end receives the frequency band resource indication information, it determines the MCS format indicated by the MCS instruction according to the used frequency band and the MCStable corresponding to the frequency band.

[0182] This application proposes a new frequency band determination method that determines the frequency band based on first information and allows the receiving end to receive multiple frequency bands simultaneously, thereby improving resource utilization. Furthermore, based on the correspondence between the frequency band and the first information, the transmitting and receiving ends can use the same algorithm to determine the frequency band, MCS configuration information, and other information, thereby reducing signaling overhead.

[0183] The BWP determines the frequency band directly based on the bandwidth required by the receiving end. However, for subcarriers with different communication capabilities under the same BWP, the available resource bandwidth is limited under a single configuration, resulting in resource waste. To improve resource utilization and more flexibly configure resources for terminals, this application further proposes a method for determining the frequency band based on the receiving end's capability information, allowing the receiving end to access multiple frequency band resources at the same time.

[0184] In some communication systems, the first information corresponds to the frequency band, which can be used to determine the frequency band. A threshold for the first information is set, and the frequency band resource blocks are determined based on the threshold. For each determined frequency band, the communication capability differences between different subcarriers can be assumed to be negligible (without affecting communication accuracy). Therefore, all resources within the frequency band can be accessed using the same scheduling information.

[0185] The following describes a specific embodiment by taking the signal-to-noise ratio of the receiving end as an example of the first information.

[0186] Example 1: The transmitting end obtains the signal-to-noise ratio (SNR) of each carrier within the bandwidth. The transmitting end directly determines the SNR threshold and determines the frequency band based on the SNR threshold. The receiving end reports the communication capability, and the transmitting end allocates bandwidth based on the information reported by the receiving end.

[0187] Step 1: The transmitter obtains the correspondence between the received signal-to-noise ratio and the frequency band position (or carrier frequency):

[0188] 1) The transmitter sends a reference signal, and the receiver uses channel estimation to obtain the signal-to-noise ratio corresponding to the frequency band position and feeds it back to the transmitter; alternatively, the transmitter directly obtains the correspondence between the signal-to-noise ratio and the frequency band position, and the transmitter can send the correspondence between the signal-to-noise ratio and the frequency band position to the receiver as needed;

[0189] Step 2: The transmitter determines the signal-to-noise ratio threshold and determines the frequency band based on the signal-to-noise ratio threshold:

[0190] 1) The transmitter directly determines the signal-to-noise ratio threshold based on an algorithm or its own experience;

[0191] 2) After the signal-to-noise ratio threshold is determined, the transmitting end determines the frequency band according to the signal-to-noise ratio threshold.

[0192] Optionally, a frequency band determination granularity may be determined, and the frequency band determination granularity and a signal-to-noise ratio threshold are comprehensively determined to ensure that the signaling overhead of the frequency band determination indication information is not excessive;

[0193] Optionally, a maximum frequency band width may be determined to prevent the frequency band interval obtained by simply using the signal-to-noise ratio threshold from being too large, so that the receiving end cannot use this frequency band.

[0194] In this step, the frequency band determination rule may require the continuity of the frequency band. A frequency band may be a continuous set of frequency resources with signal-to-noise ratios within the same range, or a discontinuous set of frequency resources with signal-to-noise ratios within the same range.

[0195] Step 3: The transmitter sends information indicating the frequency band to the receiver:

[0196] 1) The sender obtains the capability information of the receiver;

[0197] 2) The transmitting end specifies the frequency band to be used by the receiving end based on the capability information reported by the receiving end. The transmitting end may notify the receiving end of the determined frequency band determination indication information (such as one or more of the following: frequency band quantity, frequency band location), or,

[0198] The transmitting end sends the parameters required for frequency band determination (such as one or more of the following: signal-to-noise ratio threshold range, frequency band determination granularity, maximum frequency band width, etc.) to the receiving end. The receiving end uses the frequency band determination parameters to determine the frequency band (see the examples in the embodiments below for details), and then the transmitting end sends the determined frequency band determination indication information (such as the frequency band number) to the receiving end, or,

[0199] The transmitting end sends the frequency band determination parameters (such as one or more of the following: signal-to-noise ratio threshold range, frequency band determination granularity, maximum frequency band width, etc.) to the receiving end. The receiving end uses the frequency band determination parameters to perform frequency band determination (see examples in the following embodiments for details).

[0200] Step 4: The receiver and transmitter confirm the MCS Table corresponding to the frequency band used and indicate the MCS index:

[0201] The specific frequency band determination rules are as follows:

[0202] First, the frequency band is determined based on a signal-to-noise ratio threshold agreed upon by both the transmitter and receiver. After obtaining N sub-bands, the bands are numbered, perhaps in ascending order of frequency. When a receiver accesses the transmitter, the bandwidth reported by the receiver is bandwidth A, and the maximum number of simultaneously accessible bandwidths is B. After obtaining bandwidth A and bandwidth number B, the transmitter traverses the frequency bands starting from i = 1.

[0203] For the receiving end, find the frequency band whose sum of the total bandwidth of i (i starts from 1) sub-bands is in the range [xA, A] (where x ranges from 0 to 1 and the specific value is determined by the base station) and is closest to the receiving end bandwidth.

[0204] If at least one frequency band or frequency band combination that meets the conditions is found or i=B:

[0205] If i = 1, a frequency band is selected using a random number;

[0206] Otherwise, select the frequency band combination with the smallest sub-band signal-to-noise ratio range change; if there is still at least one frequency band combination that meets this condition, select a frequency band combination using a random number method;

[0207] Otherwise, when there is no band that meets the conditions after traversal:

[0208] i=i+1; re-traverse until a frequency band combination that meets the conditions is found, or when i=B, the selected frequency band is determined.

[0209] The following example illustrates this. Figure 5 The following is a graph showing the signal-to-noise ratio (SNR) obtained through channel estimation as a function of carrier frequency. The figure shows that the SNR ranges from 20 dB to 5 dB. Given that the SNR is divided into frequency band intervals for every 5 dB change, the bandwidth SNR is divided into three intervals: (5, 10], (10, 15], and (15, 20]). This frequency band requires continuity, and the final frequency band is divided into five sub-bands. Within each bandwidth interval, the same scheduling information can be used to allocate resources across the entire interval.

[0210] When the receiving end A accesses the sending end, the receiving end reports the capability information. The maximum receiving bandwidth of this receiving end is M A (Assuming this bandwidth includes Figure 5 The maximum number of frequency bands that can be received simultaneously is 1. The transmitter indicates a frequency band to the receiver A based on the communication capability report. The transmitter traverses the frequency bands and finds a frequency band with a bandwidth between [0.8M A ,M A ] and the frequency band closest to the receiving end bandwidth. When at least one frequency band that meets the conditions is found, a frequency band is selected by random number and indicated to the receiving end A. At this time, frequency band 2 and frequency band 5 meet the conditions at the same time. The frequency band to be used is calculated by random number. Assuming that the selected frequency band is frequency band 2, frequency band 2 is indicated to the receiving end A for communication.

[0211] The transmitter notifies the receiver by sending a frequency band determination instruction (including the number and location of frequency bands). Alternatively, the transmitter notifies the receiver of the rule that a frequency band is determined for every 5dB change in signal-to-noise ratio, starting from the lowest subcarrier number. The receiver determines the frequency band according to this rule. After determining the frequency band, the transmitter and receiver number the frequency bands in ascending order of frequency. The transmitter notifies the receiver of the allocated bandwidth number. Ultimately, the receiver determines the frequency band to be used as Band 2 according to the rule.

[0212] When the receiving end B accesses the sending end, the receiving end reports its capability information. The maximum receiving bandwidth of this receiving end is MB (assuming that this bandwidth includes 9 subcarriers in the figure), and the maximum number of bands that can be received simultaneously is 2. Based on the capability information, the sending end first searches for a bandwidth between [0.8M B ,M B ] and the frequency band closest to the receiving end bandwidth. After traversing, there is no frequency band that meets the conditions. Then find the frequency band whose sum of the bandwidth of the two frequency bands meets the conditions. The total bandwidth is M B The two frequency band combinations can be any combination of bands 1, 3, and 5 with any combination of bands 2 and 4. In this case, two frequency bands with the same signal-to-noise ratio range, namely bands 2 and 5, are preferably selected. In this way, the two frequency bands can use the same modulation and coding format configuration information, saving signaling overhead.

[0213] Example 2: Obtaining the SNR of Each Carrier within a Bandwidth: The transmitting end determines the SNR fluctuation range within a single frequency band, the receiving end reports the communication capability, and the transmitting end determines the bandwidth based on the communication capability reported by the receiving end and the SNR fluctuation range within the single frequency band.

[0214] Step 1: The transmitter obtains the correspondence between the received signal-to-noise ratio and the frequency band position (or carrier frequency):

[0215] 1) Sending a first reference signal, using channel estimation at the receiving end to obtain the signal-to-noise ratio corresponding to the frequency band position and feeding it back to the transmitting end; alternatively, the transmitting end directly obtains the corresponding relationship of the signal-to-noise ratio and can send this information to the receiving end as needed;

[0216] Step 2: The sender determines the signal-to-noise ratio fluctuation range and the receiver's capability information:

[0217] 1) The transmitter determines the signal-to-noise ratio fluctuation range within a single frequency band based on an algorithm or its own experience;

[0218] 2) The sender obtains the capability information of the receiver.

[0219] Step 3: The transmitter determines and indicates the frequency band based on the signal-to-noise ratio fluctuation range and the receiver's capability information:

[0220] 1) The transmitter determines the frequency band for the receiver based on the noise ratio fluctuation range and the receiver capability information;

[0221] Optionally, a frequency band determination granularity may be determined, and the frequency band may be determined based on the integrated bandwidth granularity to ensure that the signaling overhead of the frequency band determination indication information is not too large.

[0222] 2) The transmitting end may notify the receiving end of the determined frequency band determination indication information (such as one or more of the following: frequency band quantity, frequency band location), or,

[0223] The transmitting end sends the frequency band determination parameters (such as one or more of the following: signal-to-noise ratio threshold range, frequency band determination granularity, maximum frequency band width, etc.) to the receiving end. The receiving end uses the frequency band determination parameters to perform frequency band determination (see examples in the following embodiments for details).

[0224] Step 4: The receiver and transmitter confirm the MCS Table corresponding to the frequency band used and indicate the MCS index:

[0225] The specific frequency band determination rules are as follows: First, the maximum permissible signal-to-noise ratio fluctuation range within the frequency band is known to be Y. When a receiving end accesses the transmitting end, the bandwidth reported by the receiving end is A, and the maximum number of simultaneously accessible bandwidths is B. After the transmitting end obtains A and B, it starts traversing from i = 1.

[0226] For the receiver, find a carrier set with a maximum signal-to-noise ratio difference (the difference between the maximum and minimum values in the set) less than or equal to Y and a bandwidth between [xA, A] (where x ranges from 0 to 1 and the specific value is determined by the base station) that is closest to the receiver's bandwidth as a frequency band.

[0227] After traversal, if at least one frequency band that meets the conditions is found, continuous frequency bands are preferentially selected. If at least one frequency band that meets the conditions is found, random numbers are used for frequency band selection.

[0228] If there is no frequency band that meets the conditions after traversal:

[0229] The set of carriers with the largest bandwidth and the maximum signal-to-noise ratio difference less than or equal to Y is determined as a frequency band and indicated to the receiving end. If there is at least one frequency band that meets the conditions, continuous frequency bands are preferentially selected. If there is still at least one frequency band that meets the conditions, a random number is used for frequency band selection, and the final selected frequency band bandwidth is C.

[0230] If i=B, the frequency band is determined.

[0231] If i < B, then i = i + 1, and based on the above frequency band, find another sub - frequency band with a bandwidth of A = A - C for the receiving end. Repeat the traversal step until a frequency band combination that meets the conditions is found or i = B, at which point the frequency band determination is completed.

[0232] The following is an example. Assume Figure 6 is a graph showing the trend of signal - to - noise ratio varying with carrier frequency obtained through channel estimation. It can be seen from the graph that the variation range of the signal - to - noise ratio is within the range of 20 dB to 5 dB. It is known that the maximum allowable fluctuation range of the signal - to - noise ratio within the frequency band is 5 dB. This frequency band does not require continuity.

[0233] When receiving end A accesses this sending end, the receiving end reports its capability information. The maximum receiving bandwidth M A (assuming this bandwidth includes 6 sub - carriers in the graph), and the maximum number of frequency bands that can be received simultaneously is 1. The sending end determines a frequency band for receiving end A based on the reported communication capabilities and gives an indication. The sending end starts traversing from a frequency with a certain specified number, and looks for a total bandwidth of M A for receiving end with the maximum signal - to - noise ratio difference (the difference between the maximum and minimum values in the set) less than or equal to 5 dB. Assume the sending end starts traversing from the left side of the entire bandwidth, then the frequency band finally allocated to receiving end A is frequency band 1, as Figure 7 shown.

[0234] The sending end notifies the receiving end by sending frequency band determination indication information (such as including one or more of the following: number of frequency bands, frequency band position); or, the sending end sends the information that the maximum allowable fluctuation range of the signal - to - noise ratio within the allowable frequency band is 5 dB to the receiving end. The receiving end selects the accessed frequency band in the same way as the sending end (see the foregoing content).

[0235] When receiving end B accesses this sending end, the receiving end reports its capability information. The maximum receiving bandwidth of this receiving end is M B (assuming this bandwidth includes 10 sub - carriers in the graph), and the maximum number of frequency bands that can be received simultaneously is 2. Based on the capability information, the sending end first looks for a frequency band with a bandwidth between [0.8M B , M B that is closest to the receiving - end bandwidth. After traversing, it is found that there is at least one frequency band that meets the conditions. Priority is given to selecting frequency - band - continuous frequency bands. If there is at least one frequency band that meets the conditions, a random number is used for frequency - band selection. Therefore, the frequency band determined by the sending end for receiving end B is frequency band 2, as Figure 8 shown.

[0236] The transmitting end notifies the receiving end by sending frequency band determination indication information (e.g., including one or more of the following: frequency band number, frequency band location); or, the transmitting end notifies the receiving end that the maximum permissible signal-to-noise ratio fluctuation within the frequency band is 5 dB. The receiving end selects a frequency band to access using the same method as the transmitting end (see above).
