Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus and device for reporting terminal capabilities. Background Technology

[0002] Currently, standardization organizations have defined standard frequency band ranges for different frequency bands. However, in order to reduce terminal costs or due to industry implementation capabilities, terminals often only support a portion of the entire frequency band.

[0003] However, for terminals that only support a portion of the entire frequency band, various problems may arise when the frequency range supported by the terminal is a subset of the frequency range supported by its network, or when the frequency range supported by the terminal only partially overlaps with the frequency range supported by its network, affecting normal data transmission. For example, if the Synchronization Signal and PBCH block (SSB) and the initial bandwidth part (BWP) used by the network fall outside the frequency range supported by the terminal, the terminal cannot access the network; when the terminal enters connected state scheduling, it may be scheduled to a frequency range that it cannot support, resulting in packet loss, etc. Summary of the Invention

[0146] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0147] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0148] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0149] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0150] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0151] like Figure 1 As shown, an embodiment of the present invention provides a terminal capability reporting method, comprising:

[0152] Step 101: Send capability information to the network device; wherein the capability information is used to indicate the first frequency band information of the terminal, and the capability information includes at least one of the following:

[0153] Relative position to the second frequency band;

[0154] Bandwidth range;

[0155] The relative difference with the second frequency band;

[0156] The second frequency band is the frequency band supported by the network where the terminal is located.

[0157] Thus, the method of this embodiment of the invention is executed by the terminal, which informs the network device of capability information that indicates the terminal's first frequency band. Since this capability information includes at least one of the following: relative position with the second frequency band; bandwidth range; relative difference with the second frequency band; wherein the second frequency band is a frequency band supported by the network where the terminal is located, the network device can determine the terminal's first frequency band. This first frequency band belongs to the frequency range supported by the terminal, thereby facilitating the priority retrieval of frequency bands that conform to the terminal's frequency range. This not only ensures that terminals that only support a portion of the frequency bands can successfully access networks that support a wider frequency range, but also avoids packet loss during connected-state scheduling due to the network not knowing the frequency range that the terminal can operate in, thus ensuring the effectiveness and stability of data transmission.

[0158] If the second frequency band is considered as the complete frequency range, then the first frequency band can also be referred to as a partial frequency range supported by the terminal.

[0159] Of course, the first frequency band can also be the frequency range supported by the terminal.

[0160] Optionally, the relative position with respect to the second frequency band includes:

[0161] The first position, where the lowest frequency of the first frequency band is equal to the lowest frequency of the second frequency band;

[0162] In the second position, the lowest frequency of the first frequency band in the second position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is less than the center frequency of the second frequency band.

[0163] In the third position, the lowest frequency of the first frequency band in the third position is greater than the center frequency of the second frequency band, and the highest frequency of the first frequency band is less than the highest frequency of the second frequency band.

[0164] The fourth position is where the highest frequency of the first frequency band is equal to the highest frequency of the second frequency band.

[0165] In the fifth position, the lowest frequency of the first frequency band in the fifth position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is greater than the center frequency of the second frequency band but less than the highest frequency of the second frequency band.

[0166] Thus, the relative positions of the first frequency band and the second frequency band can be the first position, the second position, the third position, the fourth position, or the fifth position mentioned above.

[0167] For example, the first frequency band is frequency band M, and the second frequency band is frequency band N. If... Figure 2 As shown, if frequency band M starts at the lowest frequency of frequency band N, then the relative position of frequency band M and frequency band N is the first position. If... Figure 3 As shown, the lowest frequency of frequency band M is higher than the lowest frequency of frequency band N, but the highest frequency of frequency band M is lower than the center frequency of frequency band N. Therefore, the relative position of frequency band M and frequency band N is the second position. If... Figure 4 As shown, the lowest frequency of frequency band M is higher than the center frequency of frequency band N, but the highest frequency of frequency band M is lower than the highest frequency of frequency band N. Therefore, the relative position of frequency band M and frequency band N is the third position. If... Figure 5 As shown, the highest frequency of frequency band M is equal to the highest frequency of frequency band N, therefore the relative position of frequency band M and frequency band N is the fourth position. If... Figure 6 As shown, the lowest frequency of frequency band M is lower than the center frequency of frequency band N, but the highest frequency of frequency band M is higher than the center frequency of frequency band N. Therefore, the relative position of frequency band M and frequency band N is the fifth position.

[0168] Optionally, the bandwidth range of the first frequency band is indicated based on multiple pre-divided ranges. For example, the pre-divided ranges may include: [0, A], (A, B], (B, C], etc. Each range can be uniformly divided or non-uniformly divided, such as the boundary points increasing in the following order: 20MHz, 30MHz, 40MHz, 50MHz, 60MHz, 70MHz, 80MHz, 90MHz, 100MHz, 150MHz, 200MHz, 300MHz, 400MHz, 500MHz, 600MHz, 700MHz, 800MHz, 900MHz…

[0169] In addition, in this embodiment, optionally, the relative difference with the second frequency band is the range of the frequency difference between the first frequency of the first frequency band and the second frequency of the second frequency band.

[0170] Optionally, the first frequency includes at least one of the following in the first frequency band: the lowest frequency; the center frequency; and the highest frequency.

[0171] The second frequency includes at least one of the following: the lowest frequency; the center frequency; and the highest frequency.

[0172] Therefore, the range of frequency difference between the first frequency and the second frequency can include the following types: the range of frequency difference between the lowest frequency of the first frequency band and the lowest frequency of the second frequency band, or the range of frequency difference between the lowest frequency of the first frequency band and the center frequency of the second frequency band, or the range of frequency difference between the lowest frequency of the first frequency band and the highest frequency of the second frequency band, etc., which will not be listed here.

[0173] Of course, the relative difference between the first and second frequency bands transmitted by the terminal is not limited to a single type of frequency difference; it can be a range of multiple types of frequency differences. For example, ... Figure 2 As shown, the relative differences transmitted to the network device include the range of frequency difference Δ1 between the center frequency of band M and the center frequency of band N, and the range of frequency difference Δ2 between the highest frequency of band M and the highest frequency of band N; for example Figure 3 As shown, the relative differences sent to the network device include the range of frequency difference Δ3 between the lowest frequency of band M and the lowest frequency of band N, and the range of frequency difference Δ4 between the highest frequency of band M and the center frequency of band N.

[0174] It should be known that the relative positions between frequency bands are... Figure 2 As shown, if the capability information includes the relative position, then the relative difference included in the capability information can be the range of the difference between the center frequency / highest frequency of the first frequency band and the center frequency / highest frequency of the second frequency band; for the relative position between frequency bands... Figure 5 As shown, if the capability information includes the relative position, then the relative difference included in the capability information can be the range of the difference between the center frequency / lowest frequency of the first frequency band and the center frequency / lowest frequency of the second frequency band.

[0175] In this embodiment, the range of relative differences between frequency bands can also be pre-divided. For example, multiple pre-divided ranges include: [0, A'], (A', B'], (B', C'], etc. Each range can be uniformly divided or non-uniformly divided, such as the boundary points arranged from smallest to largest as 10MHz, 20MHz, 30MHz, 40MHz, 50MHz, 60MHz, 70MHz, 80MHz, 90MHz, 100MHz, 150MHz, 200MHz, 300MHz, 400MHz, 500MHz, 600MHz, 700MHz, 800MHz, 900MHz…

[0176] Alternatively, in this embodiment, the capability information is sent via target signaling; wherein,

[0177] The target signaling is dedicated to the transmission of the capability information; or...

[0178] The target signaling is multiplexed for the transmission of the capability information.

[0179] In this way, the newly added terminal capability reporting signaling can be used as the target signaling dedicated to the transmission of the capability information; or, the existing terminal capability reporting signaling can be used as the target signaling reused for the transmission of the capability information.

[0180] Optionally, the target signaling identifies different capability information by carrying different indication information of a preset bit length.

[0181] Here, for the relative position, bandwidth range, and relative difference with the second frequency band, the corresponding indication information has a corresponding preset bit length. For example, the preset bit length of the indication information indicating the relative position with the second frequency band is a first value, the preset bit length of the indication information indicating the bandwidth range is a second value, and the preset bit length of the indication information indicating the relative difference with the second frequency band is a third value. If the indication information corresponds to two or three of the relative position, bandwidth range, and relative difference with the second frequency band, the preset bit length of the indication channel is the sum of these two or three values. For example, if the indication information corresponds to the relative position and bandwidth range with the second frequency band, then the preset bit length is the first value + the second value. The preset bit lengths of the indication information for the relative position, bandwidth range, and relative difference with the second frequency band can be preset.

[0182] Thus, for at least one of the relative position, bandwidth range, and relative difference with the second frequency band, the target signaling identifies different capability information through different indication information. Of course, for target signaling that multiplexes the transmission of this capability information, a new field is added to the target signaling or an idle field is used to carry the indication information of the capability information. Compared to directly transmitting the relative position, bandwidth range, and relative difference with the second frequency band, transmitting its indication information can effectively save system resources.

[0183] Scenario 1: Assume that the capability information includes the relative position with respect to the second frequency band, and the preset bit length of the indication information (i.e., the first field IE) corresponding to the relative position with respect to the second frequency band is 2.

[0184] Then, when the first field is 00, it means that the first frequency band starts at the lowest frequency end of the second frequency band (complete frequency range), such as: the first frequency band is 2496~2515MHz, located at the lowest frequency end of the second frequency band (2496~2690MHz) corresponding to n41; when the first field is 01, it means that the first frequency band ends at the highest frequency end of the second frequency band, such as: the first frequency band is 2515~2690MHz, located at the highest frequency end of the second frequency band (2496~2690MHz) corresponding to n41; when the first field is 10, the first frequency band neither starts at the lowest frequency end nor ends at the highest frequency end of the second frequency band, but is located in the middle region of the second frequency band, and the center frequency of the first frequency band is lower than the center frequency of the second frequency band, such as: the first The frequency band is 2555~2575MHz, located in the middle region of the second frequency band (2496~2690MHz) corresponding to n41, and the center frequency of the first frequency band 2565MHz is lower than the center frequency of the second frequency band 2593MHz; when the first field is 11, it means that the first frequency band neither starts at the lowest frequency end of the second frequency band nor ends at the highest frequency end of the second frequency band, but is located in the middle region of the second frequency band, and the center frequency of the first frequency band is higher than the center frequency region of the second frequency band. For example, the first frequency band is 2515~2675MHz, located in the middle region of the second frequency band (2496~2690MHz) corresponding to n41, and the center frequency of the first frequency band 2595MHz is higher than the center frequency of the second frequency band 2593MHz.

[0185] Thus, after the network device receives the target signaling, if it learns through the first field = 00 that the terminal's first frequency band is in the lower part of the current frequency band, then during connection-mode scheduling, frequency resources in the lower frequency band should be prioritized; if it learns through the first field = 01 that the terminal's first frequency band is in the higher part of the current frequency band, then during connection-mode scheduling, frequency resources in the higher frequency band should be prioritized; if it learns through the first field = 10 that the terminal's first frequency band is in the lower-mid frequency part of the current frequency band, then during connection-mode scheduling, frequency resources in the lower-mid frequency band should be prioritized; if it learns through the first field = 11 that the terminal's first frequency band is in the higher-mid frequency part of the current frequency band, then during connection-mode scheduling, frequency resources in the higher-mid frequency band should be prioritized.

[0186] Scenario 2: Assume that the capability information includes the bandwidth range, and the preset bit length of the indication information (i.e., the second field IE) corresponding to the bandwidth range is 4.

[0187] When the second field is 0000, it represents the bandwidth range of the terminal's first frequency band as (0, A], where A = 20MHz; when the second field is 0001, it represents the bandwidth range of the terminal's first frequency band as (A, B], where A = 20MHz and B = 30MHz; when the second field is 0010, it represents the bandwidth range of the terminal's first frequency band as (B, C], where B = 30MHz and C = 40MHz; when the second field is 0011, it represents the bandwidth range of the terminal's first frequency band as (C, D], where C = 40MHz and D = 50MHz. MHz; when the second field is 0100, it represents the bandwidth range of the terminal's first frequency band as (D,E], where D = 50MHz and E = 60MHz; when the second field is 0101, it represents the bandwidth range of the terminal's first frequency band as (E,F], where E = 60MHz and F = 70MHz; when the second field is 0110, it represents the bandwidth range of the terminal's first frequency band as (F,G], where F = 70MHz and G = 80MHz; when the second field is 0111, it represents the bandwidth range of the terminal's first frequency band as (G,H], where G... =80MHz, H=90MHz; when the second field is 1000, it represents the bandwidth range of the terminal's first frequency band as (H,I], where H=90MHz, I=100MHz; when the second field is 1001, it represents the bandwidth range of the terminal's first frequency band as (I,J], where I=100MHz, J=110MHz; when the second field is 1010, it represents the bandwidth range of the terminal's first frequency band as (J,K], where J=110MHz, K=120MHz; when the second field is 1011, it represents the bandwidth range of the terminal's first frequency band as (J,K], where J=110MHz, K=120MHz; The bandwidth range of the first frequency band is (K,L], where K = 120MHz and L = 130MHz; when the second field is 1100, it represents the bandwidth range of the first frequency band of the terminal as (L,M], where L = 130MHz and M = 140MHz; when the second field is 1101, it represents the bandwidth range of the first frequency band of the terminal as (M,N], where M = 140MHz and N = 150MHz; when the second field is 1110, it represents the bandwidth range of the first frequency band of the terminal as (N,O], where N = 150MHz and O = 160MHz.

[0188] Thus, if the bandwidth of the terminal's first frequency band is 15MHz or 20MHz, the terminal reports the second field as 0000; if the bandwidth of the terminal's first frequency band is 25MHz or 30MHz, the terminal reports the second field as 0001; if the bandwidth of the terminal's first frequency band is 35MHz or 40MHz, the terminal reports the second field as 0010; if the bandwidth of the terminal's first frequency band is 45MHz or 50MHz, the terminal reports the second field as 0011; if the bandwidth of the terminal's first frequency band is 55MHz or 60MHz, the terminal reports the second field as 0100; if the bandwidth of the terminal's first frequency band is 65MHz or 70MHz, the terminal reports the second field as 0101; if the bandwidth of the terminal's first frequency band is 75MHz or 80MHz, the terminal reports the second field as 0110; if the bandwidth of the terminal's first frequency band is 85MHz or 90MHz, then... The terminal reports the second field as 0111; if the bandwidth of the terminal's first frequency band is 95MHz or 100MHz, the terminal reports the second field as 1000; if the bandwidth of the terminal's first frequency band is 105MHz or 110MHz, the terminal reports the second field as 1001; if the bandwidth of the terminal's first frequency band is 115MHz or 120MHz, the terminal reports the second field as 1010; if the bandwidth of the terminal's first frequency band is 125MHz or 130MHz, the terminal reports the second field as 1011; if the bandwidth of the terminal's first frequency band is 135MHz or 140MHz, the terminal reports the second field as 1100; if the bandwidth of the terminal's first frequency band is 145MHz or 150MHz, the terminal reports the second field as 1101; if the bandwidth of the terminal's first frequency band is 155MHz or 160MHz, the terminal reports the second field as 1110.

[0189] Scenario 3: Assume that the capability information includes the relative difference with the second frequency band, and the preset bit length of the indication information (i.e., the third field IE) corresponding to the relative difference with the second frequency band is 2.

[0190] When the third field is 00, it represents the approximate range of the difference between the center frequency / lowest frequency / highest frequency of the first frequency band and the center frequency / lowest frequency / highest frequency of the second frequency band as [0, A'], where A' = 10MHz; when the third field is 01, it represents the approximate range of the difference between the center frequency / lowest frequency / highest frequency of the first frequency band and the center frequency / lowest frequency / highest frequency of the second frequency band as (A', B'], where A' = 10MHz and B' = 20MHz; when the third field is 10, it represents the approximate range of the difference between the center frequency / lowest frequency / highest frequency of the first frequency band and the center frequency / lowest frequency / highest frequency of the second frequency band as (B', C'], where B' = 20MHz and C' = 30MHz.

[0191] Thus, if the difference between the center frequency / minimum frequency / maximum frequency of the first frequency band and the center frequency / minimum frequency / maximum frequency of the second frequency band is 5MHz or 10MHz, the terminal reports the third field as 00; if the difference between the center frequency / minimum frequency / maximum frequency of the first frequency band and the center frequency / minimum frequency / maximum frequency of the second frequency band is 15MHz or 20MHz, the terminal reports the third field as 01; if the difference between the center frequency / minimum frequency / maximum frequency of the first frequency band and the center frequency / minimum frequency / maximum frequency of the second frequency band is 25MHz or 30MHz, the terminal reports the third field as 10.

[0192] Thus, considering the above scenario, when terminal 1 corresponds to the n28 frequency band, such as Figure 7 and 8 As shown, only the low-frequency band of 30MHz is supported: n28A (703-733MHz, 758~788MHz):

[0193] If so Figure 7 As shown, the first field is 00, indicating that the terminal's first frequency band starts at the lowest frequency end of the complete frequency range; the second field is 0001, indicating that the approximate bandwidth range of the terminal's first frequency band is (20MHz, 30MHz); the third field is 00, indicating that the approximate range of the difference between the center frequency of the terminal's first frequency band and the center frequency of the complete frequency band is [0, 10MHz]. Therefore, network devices such as base stations can calculate that the minimum possible center frequency of the terminal's first frequency band is 715.5MHz, starting from 703MHz, so the actual minimum frequency range of this band should be [703MHz, 728MHz]. Therefore, when the terminal enters the connected state scheduling, the base station should schedule frequency resources close to the lower frequency band within the complete frequency band range, that is, the network should schedule frequency resources within the 25MHz range of [703MHz, 728MHz] to ensure that no packet loss occurs.

[0194] Or, such as Figure 8 As shown, the third field is 01, representing the approximate range of the difference between the highest frequency of the terminal's first frequency band and the highest frequency of the complete frequency band (10MHz, 20MHz). Accordingly, the base station can calculate that the lowest possible highest frequency of the terminal's first frequency band is 728MHz, starting from 703MHz. Therefore, the actual minimum frequency range of this band should be [703MHz, 728MHz]. Thus, when the terminal enters connected state scheduling, the base station should schedule frequency resources within the complete frequency band that are closer to the lower frequency band, i.e., schedule frequency resources within the 25MHz range of [703MHz, 728MHz], to ensure that no packet loss occurs.

[0195] Therefore, this solves the incompatibility issue that may occur when roaming to a network that supports a wider frequency range, since the n28 band only supports (703-733MHz, 758-788MHz) on the terminal.

[0196] Based on the above scenario, when terminal 2 corresponds to the n41 frequency band, such as Figure 9-11 As shown, only a portion of the intermediate frequency band (160MHz): 2515-2675MHz is supported.

[0197] If so Figure 9 As shown, the first field is 11, indicating that the terminal's first frequency band neither starts at the lowest frequency nor ends at the highest frequency, but is located in the middle region of the complete frequency range, and the center frequency of the terminal's first frequency band is higher than the center frequency of the complete frequency range; the second field is 1110, indicating that the approximate bandwidth range of the terminal's first frequency band is (150MHz, 160MHz); the third field is 00, indicating that the approximate range of the difference between the center frequency of the terminal's first frequency band and the center frequency of the complete frequency band is [0, 10MHz]. Therefore, the base station can calculate that the possible region where the center frequency of the terminal's first frequency band may appear is [2593MHz]. [2593MHz]—If the center frequency is 2593MHz, then the minimum possible frequency range Range1 for this band should be [2518MHz, 2668MHz]; if the center frequency is 2603MHz, then the minimum possible frequency range Range2 for this band should be [2528MHz, 2678MHz]. Therefore, when the terminal enters the connected state scheduling, the base station should schedule frequency resources within the overlapping frequency range of Range1 and Range2, that is, schedule frequency resources within the 140MHz frequency band range of [2528MHz, 2668MHz], to ensure that no packet loss occurs.

[0198] Or, such as Figure 10As shown, the third field is 01, representing the approximate range of the difference between the lowest frequency of the terminal's first frequency band and the lowest frequency of the complete frequency band (10MHz, 20MHz). The base station can calculate that the possible range of the lowest frequency of the terminal's first frequency band is [2506MHz, 2516MHz]—if the lowest frequency is 2506MHz, then the possible minimum frequency range Range1 of this band should be [2506MHz, 2656MHz]; if the lowest frequency is 2516MHz, then the possible minimum frequency range Range2 of this band should be [2516MHz, 2666MHz]. Therefore, when the terminal enters the connected state scheduling, the base station should schedule frequency resources within the overlapping frequency range of Range1 and Range2, that is, schedule frequency resources within the 140MHz frequency band range of [2516MHz, 2656MHz], to ensure that no packet loss occurs.

[0199] Or, such as Figure 11 As shown, the third field is 01, representing the approximate range of the difference between the highest frequency of the terminal's first frequency band and the highest frequency of the complete frequency band (10MHz, 20MHz). The base station can calculate that the possible range of the highest frequency of the terminal's first frequency band is [2670MHz, 2680MHz]—if the highest frequency is 2670MHz, then the possible minimum frequency range Range1 should be [2520MHz, 2670MHz]; if the highest frequency is 2680MHz, then the possible minimum frequency range Range2 should be [2530MHz, 2680MHz]. Therefore, when the terminal enters the connected state scheduling, the base station should schedule frequency resources within the overlapping frequency range of Range1 and Range2, that is, schedule frequency resources within the 140MHz frequency band range of [2530MHz, 2670MHz], to ensure that no packet loss occurs.

[0200] Therefore, this solves the incompatibility issue that may occur when roaming to a network that supports a wider frequency range, since the n41 band only supports (2515-2675MHz) on the terminal.

[0201] The estimation of the available frequency range for base station scheduling is based on the "center frequency," "lowest frequency," or "highest frequency." The estimation result is a total available frequency range of 140MHz that guarantees no packet loss—the effective frequency utilization rate is 140MHz / 160MHz = 87.5%. The terminal needs to use a total of 8 bits for reporting the first, second, and third fields. If both the "lowest frequency" and "highest frequency" are used to estimate the available frequency range for network scheduling, and the union of the frequency ranges estimated using the "lowest frequency" and "highest frequency" is taken, the estimation result is a total available frequency range of 154MHz [2516MHz, 2670MHz] that guarantees no packet loss—the effective frequency utilization rate is 154MHz / 160MHz = 96.25%. The terminal needs to use a total of 10 bits for reporting the first, second, and third fields.

[0202] In summary, the method of this embodiment informs the network device of capability information that indicates the first frequency band of the terminal. This capability information includes at least one of the following: relative position to the second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. Therefore, the network device can determine the terminal's first frequency band, which falls within the frequency range supported by the terminal. This allows for priority access to frequency bands that match the terminal's frequency range. This not only ensures that terminals supporting only a portion of the frequency bands can successfully access networks supporting a wider frequency range, but also avoids packet loss during connected-state scheduling due to the network's lack of knowledge about the terminal's operating frequency range, thus guaranteeing the effectiveness and stability of data transmission.

[0203] It should also be noted that in this embodiment, the capability information includes the bandwidth range of the first frequency band. When facing the addition of some frequency bands supported by the terminal in the second frequency band, there is no need to update the reporting fields, which reduces network maintenance overhead, reduces terminal development complexity, reduces the probability of incompatibility issues between old and new versions due to updating the reporting fields, and more broadly adapts to more terminal types with a wider range of frequency ranges.

[0204] like Figure 12 As shown, an embodiment of the present invention provides a terminal capability reporting method, comprising:

[0205] Step 1201: Receive capability information sent by the terminal; wherein the capability information is used to indicate information about the first frequency band of the terminal, and the capability information includes at least one of the following:

[0206] Relative position to the second frequency band;

[0207] Bandwidth range;

[0208] The relative difference with the second frequency band;

[0209] The second frequency band is the frequency band supported by the network where the terminal is located.

[0210] The method of this invention is executed by a network device. It receives capability information from a terminal indicating the terminal's first frequency band. This capability information includes at least one of the following: relative position to a second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. Therefore, the network device can subsequently determine the terminal's first frequency band based on this capability information. Since the first frequency band belongs to the frequency range supported by the terminal, it can preferentially retrieve frequency bands that match the terminal's frequency range. This not only ensures that terminals supporting only a portion of the frequency bands can successfully access networks that support a wider frequency range, but also avoids packet loss during connected-state scheduling due to the network not knowing the frequency range the terminal can operate in, thus ensuring the effectiveness and stability of data transmission.

[0211] Optionally, after the capability information sent by the receiving terminal, the system further includes:

[0212] Based on the capability information, the first frequency band is determined.

[0216] In the third position, the lowest frequency of the first frequency band in the third position is greater than the center frequency of the second frequency band, and the highest frequency of the first frequency band is less than the highest frequency of the second frequency band.

[0217] The fourth position is where the highest frequency of the first frequency band is equal to the highest frequency of the second frequency band.

[0218] In the fifth position, the lowest frequency of the first frequency band in the fifth position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is greater than the center frequency of the second frequency band but less than the highest frequency of the second frequency band.

[0219] Optionally, the relative difference with the second frequency band is the range of frequency difference between the first frequency of the first frequency band and the second frequency of the second frequency band.

[0223] The target signaling is dedicated to the transmission of the capability information; or...

[0224] The target signaling is multiplexed for the transmission of the capability information.

[0225] Optionally, the target signaling identifies different capability information by carrying different indication information of a preset bit length.

[0226] It should be noted that this method is implemented in conjunction with the method executed by the terminal described above. The implementation of the method executed by the terminal described above is applicable to this method and can achieve the same technical effect.

[0227] like Figure 13 As shown, a terminal capability reporting device according to an embodiment of the present invention includes:

[0236] In the third position, the lowest frequency of the first frequency band in the third position is greater than the center frequency of the second frequency band, and the highest frequency of the first frequency band is less than the highest frequency of the second frequency band.

[0237] The fourth position is where the highest frequency of the first frequency band is equal to the highest frequency of the second frequency band.

[0238] In the fifth position, the lowest frequency of the first frequency band in the fifth position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is greater than the center frequency of the second frequency band but less than the highest frequency of the second frequency band.

[0245] Optionally, the target signaling identifies different capability information by carrying different indication information of a preset bit length.

[0246] The device informs the network device of its capability information, which indicates the terminal's first frequency band. This capability information includes at least one of the following: relative position to the second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. The network device can then determine the terminal's first frequency band, which falls within the frequency range supported by the terminal. This allows it to prioritize the selection of frequency bands that match the terminal's frequency range. This not only ensures that terminals that only support a portion of the frequency bands can successfully access networks that support a wider frequency range, but also prevents packet loss during connected-state scheduling due to the network's lack of knowledge about the terminal's operating frequency range, thus guaranteeing the effectiveness and stability of data transmission.

[0247] It should be noted that the device uses the terminal capability reporting method executed by the terminal described above. The implementation of the above method embodiment is applicable to this device and can achieve the same technical effect.

[0269] The device receives capability information from the terminal indicating the terminal's first frequency band. This capability information includes at least one of the following: relative position to the second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. Therefore, the network device can subsequently determine the terminal's first frequency band based on this capability information. Since the first frequency band belongs to the frequency range supported by the terminal, the device can prioritize the selection of frequency bands that match the terminal's frequency range. This not only ensures that terminals that only support a portion of the frequency bands can successfully access networks that support a wider frequency range, but also avoids packet loss during connected-state scheduling due to the network not knowing the frequency range that the terminal can operate in, thus ensuring the effectiveness and stability of data transmission.

[0270] It should be noted that the device uses the terminal capability reporting method executed by the network device described above. The implementation of the above method embodiment is applicable to this device and can achieve the same technical effect.

[0271] like Figure 15 As shown, a terminal 1500 according to an embodiment of the present invention includes a transceiver 1510;

This capability information includes at least one of the following: relative position to the second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. The network device can then determine the terminal's first frequency band, which falls within the frequency range supported by the terminal. This allows the network device to prioritize the selection of frequency bands that match the terminal's frequency range. This not only ensures that terminals that only support a portion of the frequency bands can successfully access networks that support a wider frequency range, but also prevents packet loss during connected-state scheduling due to the network's lack of knowledge about the terminal's operating frequency range, thus ensuring the effectiveness and stability of data transmission.

[0291] It should be noted that the terminal uses the terminal capability reporting method executed by the terminal described above. The implementation of the above method embodiment is applicable to this terminal and can achieve the same technical effect.

[0295] Bandwidth range;

[0296] The relative difference with the second frequency band;

[0297] The second frequency band is the frequency band supported by the network where the terminal is located.

[0298] Optionally, the network device 1600 further includes a processor 1620;

[0299] The processor 1620 is used to determine the first frequency band based on the capability information.

[0300] Optionally, the relative position with respect to the second frequency band includes:

[0302] In the second position, the lowest frequency of the first frequency band in the second position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is less than the center frequency of the second frequency band.

[0303] In the third position, the lowest frequency of the first frequency band in the third position is greater than the center frequency of the second frequency band, and the highest frequency of the first frequency band is less than the highest frequency of the second frequency band.

[0304] The fourth position is where the highest frequency of the first frequency band is equal to the highest frequency of the second frequency band.

[0305] In the fifth position, the lowest frequency of the first frequency band in the fifth position is greater than the lowest frequency of the second frequency band, and the highest frequency of the first frequency band is greater than the center frequency of the second frequency band but less than the highest frequency of the second frequency band.

[0306] Optionally, the relative difference with the second frequency band is the range of frequency difference between the first frequency of the first frequency band and the second frequency of the second frequency band.

[0307] Optionally, the first frequency includes at least one of the following in the first frequency band: the lowest frequency; the center frequency; and the highest frequency.

[0311] The target signaling is multiplexed for the transmission of the capability information.

[0312] Optionally, the target signaling identifies different capability information by carrying different indication information of a preset bit length.

[0313] The network device receives capability information from the terminal indicating the terminal's first frequency band. This capability information includes at least one of the following: relative position to the second frequency band; bandwidth range; and relative difference to the second frequency band. The second frequency band is a frequency band supported by the network where the terminal is located. Therefore, the network device can subsequently determine the terminal's first frequency band based on this capability information. Since the first frequency band belongs to the frequency range supported by the terminal, it can prioritize the selection of frequency bands that match the terminal's frequency range. This not only ensures that terminals supporting only a portion of the frequency bands can successfully access networks that support a wider frequency range, but also avoids packet loss during connected-state scheduling due to the network not knowing the frequency range the terminal can operate in, thus guaranteeing the effectiveness and stability of data transmission.
