[0036] The following explains the relevant technologies involved in this application.

[0037] I. Radio Frequency Requirements for Band 28

[0038] In mobile communications, in the Frequency Division Duplex (FDD) band, a duplexer is an essential component in the radio frequency link to enable simultaneous transmission and reception by terminals. Due to technological limitations, the achievable bandwidth of a duplexer is generally assumed to be 3% to 4% of the center frequency. The transmission and reception capabilities of LTE and NR terminals are also based on this assumption.

[0039] The transmit / receive capability requirements for terminals in Long Term Evolution (LTE) and New Radio (NR) mid-band 28 (703MHz–748MHz, 758MHz–803MHz) are based on this assumption. Band 28 has 45MHz of available bandwidth. Due to bandwidth limitations in duplexer implementation, the terminal requires two 30MHz duplexers (with a 15MHz overlap in between) to support this 45MHz available bandwidth. When the network schedules this terminal, the default maximum available bandwidth is only 30MHz, and the scheduling frequency is also limited. For uplink, it can only fall within 703-733MHz or 718-748MHz, thus failing to fully utilize the entire bandwidth.

[0040] To protect Channel 52 of Japan's digital television network, the 3rd Generation Partnership Project (3GPP) introduced an additional radiation protection requirement: NS_17. When a terminal receives NS_17 and uses the 718-748MHz band with channel bandwidths of 3MHz, 5MHz, and 10MHz, radiation in the 470-710MHz band should be kept below -26.2dBm (measured bandwidth 6MHz). Since 710MHz is already within the uplink transmission band of band 28, existing two-duplex architectures can meet the NS_17 radiation requirements.

[0041] II. Dual PA Architecture under Carrier Aggregation

[0042] To support carrier aggregation in high-bandwidth frequency bands, 3GPP introduced the dual PA architecture, or dual PA-Architecture. When a terminal reports a dual PA-Architecture, the terminal uses two PAs to transmit simultaneously to support wider bandwidth, that is, one PA supports one subcarrier (Component Carrier, CC).

[0043] III. 5G Terminals in FR1 (410-7125MHz) Channel Bandwidth

[0044] The maximum channel bandwidth supported by 5G terminals in FR1 is 100MHz, while the allocated 5G frequency band bandwidth can support up to 600MHz (such as n79 4400-5000MHz). For support of large bandwidth, terminals need to support intra-band contiguous carrier aggregation (CA).

[0045] The communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0046] Figure 2 A flowchart illustrating the communication method provided in the embodiments of this application is shown below. Figure 2 As shown, the communication method may include the following steps 201 and 202:

[0047] Step 201: The terminal sends or receives signals through M radio frequency links.

[0048] Each RF link includes at least one power amplifier and a duplexer or bandpass filter connected to the at least one power amplifier. Different RF links are used to transmit or receive signals at different frequency ranges within the same frequency band, and M is an integer greater than 1.

[0049] In some embodiments of this application, the terminal may transmit signals simultaneously through M radio frequency links, or transmit signals through M radio frequency links at different times.

[0050] In some embodiments of this application, the terminal may receive signals simultaneously through M radio frequency links, or receive signals through M radio frequency links at different times.

[0051] In some embodiments of this application, each radio frequency link includes a set of power amplifiers, each set of power amplifiers corresponding to a duplexer or a bandpass filter, wherein the set of power amplifiers may include one or more power amplifiers.

[0052] In some embodiments of this application, the aforementioned M radio frequency links may include M transmitting radio frequency links, or M receiving radio frequency links, or N transmitting radio frequency links and MN receiving radio frequency links, where N is a positive integer less than M.

[0053] For example, the above M radio frequency links may include two radio frequency links, four radio frequency links, or six radio frequency links.

[0054] It should be noted that the number of radio frequency links can be determined based on the bandwidth of the frequency band that actually needs to be covered. For example, when it is necessary to cover a frequency band with a larger bandwidth, more radio frequency links can be designed to cover the frequency band with a larger bandwidth. The embodiments of this application do not limit the number of radio frequency links.

[0055] It is understandable that a radio frequency link is a single radio frequency link.

[0056] In some embodiments of this application, the M radio frequency links respectively cover different frequency ranges within the same frequency band. Further, the same frequency band can be a frequency band with bandwidth exceeding a threshold (i.e., a large bandwidth frequency band) or an irregular frequency band.

[0057] It's important to note that high bandwidth typically refers to the network's ability to transmit data at high rates, enabling terminals to quickly upload and download large amounts of data. Irregular bandwidth, on the other hand, generally refers to bandwidth that does not conform to the standard bandwidth defined in a specific technical standard. For example, in the LTE standard, in addition to the six specified standard carrier bandwidths (1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz), other carrier bandwidths are considered irregular or non-standard bandwidths.

[0058] In related technologies, supporting large bandwidth requires high costs and the utilization rate of irregular frequency bands is low, resulting in spectrum waste. The communication method provided in this application covers different frequency ranges within large bandwidth or irregular bandwidth frequency bands through multiple radio frequency links, thereby better supporting both large bandwidth and irregular bandwidth frequency bands, reducing costs, and improving spectrum utilization.

[0059] It should be noted that the term "same frequency band" refers to any frequency band that needs to be used, rather than a specific frequency band. For example, the same frequency band could be band 28 (n28), band 83 (n83), or other frequency bands.

[0060] In some embodiments of this application, in a frequency division duplex (FDD) system, each radio frequency link includes at least one power amplifier and a duplexer, or in a time division duplex (TDD) system, each radio frequency link includes at least one power amplifier and a bandpass filter.

[0061] For example, in an FDD system, the above M RF links may include four RF links, each RF link including a set of power amplifiers and a duplexer, and each RF link covering a different frequency range within the N28 band.

[0062] As another example, in a TDD system, the aforementioned M RF links may include eight RF links, each RF link including a set of power amplifiers and a bandpass filter, and each RF link covering different frequency ranges within a large bandwidth band.

[0063] It should be noted that a duplexer typically consists of a transmit filter and a receive filter, which allow signals within a specific frequency range to pass through while blocking signals at other frequencies. In FDD systems, because the uplink and downlink use different frequency channels, each RF link needs to include at least one power amplifier and one duplexer. The power amplifier amplifies the transmitted signal, and the duplexer separates and combines the uplink and downlink signals on the same antenna.

[0064] Similarly, in TDD systems, because uplink and downlink use different time slots of the same frequency channel, each RF link needs to include at least one power amplifier. However, in TDD systems, since uplink and downlink do not occur simultaneously, there is no need to use a duplexer to separate the signals. Therefore, a bandpass filter can be used to filter out unwanted frequency components to ensure signal quality.

[0065] Step 202: The terminal sends the first signaling to the network-side device.

[0066] The first signaling mentioned above includes information on the frequency range covered by the terminal's radio frequency link and / or the terminal's operating mode information on the radio frequency link.

[0067] In some embodiments of this application, the network-side equipment described above may be a base station or a core network device.

[0068] In some embodiments of this application, the frequency range covered by the radio frequency links of the terminal may include at least one of the following: the frequency range covered by each radio frequency link of the terminal, the total frequency range covered by all radio frequency links of the terminal, the frequency range covered by the radio frequency links of the terminal that simultaneously receive or transmit signals, and the total frequency range covered by the radio frequency links of the terminal that simultaneously receive or transmit signals.

[0069] It should be noted that the terminal reports overlapping frequency ranges to indicate the stronger transmission capability of that part of the frequency range, including but not limited to higher power levels, transmit diversity, or UL MIMO.

[0070] In some embodiments of this application, the above-mentioned operating mode information may include, but is not limited to, at least one of the following: receiving parameters, transmitting power, antenna and beam information, modulation and demodulation parameters, radio frequency link control information, frequency allocation and channel selection information, etc.

[0071] In some embodiments of this application, the first signaling may further include at least one of the total number of radio frequency links of the terminal and the number of radio frequency links used by the terminal when simultaneously receiving or transmitting signals.

[0072] In some embodiments of this application, there is at least partial overlap between the frequency range covered by each radio frequency link and the frequency range covered by other radio frequency links supporting the same frequency band.

[0073] For example, the frequency ranges covered by multiple radio frequency links may partially overlap, or the frequency ranges covered by multiple radio frequency links may completely overlap.

[0074] In some embodiments of this application, when the frequency ranges covered by M radio frequency links completely overlap, it indicates that the M radio frequency links repeatedly cover the entire frequency range of the same frequency band (i.e., the first frequency band).

[0075] In some embodiments of this application, in order to compensate for the process limitations of the filter in achieving the filtering bandwidth edge, there may be additional frequency overlap between the frequency ranges covered by the duplexer (or bandpass filter), and the frequency overlap range may be [0%, 100%].

[0076] In some embodiments of this application, the terminal adds a new radio frequency link to achieve repeated coverage of the remaining frequency band, thereby completing repeated coverage of the entire frequency band to achieve transmit diversity, ULMIMO, receive diversity, power, and power level across the entire bandwidth.

[0077] Furthermore, when multiple RF links together achieve 100% overlapping coverage of large or irregular bandwidths, the superposition of multiple RF links can realize seamless (unprotected band) support for large and irregular bandwidths, while also enabling transmit diversity, UL MIMO, and receive diversity.

[0078] In some embodiments of this application, the M radio frequency links described above are used for transmit diversity, ULMIMO, or receive diversity in a first frequency band.

[0079] For example, for a frequency range in the first frequency band that is overlapped and covered by multiple radio frequency links, the terminal can use transmit diversity, UL MIMO or receive diversity to transmit or receive signals within the overlapped frequency range.

[0080] It should be noted that overlapping coverage can also be called repeated coverage, which means that the same frequency range is covered multiple times.

[0081] It should be noted that transmit diversity improves the reliability of received signals by increasing signal redundancy; uplink MIMO improves data transmission rate and spectral efficiency by utilizing spatial multiplexing and spatial diversity effects; and receive diversity improves the signal-to-noise ratio and reliability of received signals by combining signals from multiple receiving antennas.

[0082] It should be noted that the first frequency band can be the same frequency band mentioned above.

[0083] The communication method provided in this application, for a single frequency band with large or ultra-large bandwidth, or irregular bandwidth, introduces multiple radio frequency (RF) links in the terminal. Each RF link consists of a set of power amplifiers and a duplexer or bandpass filter. Multiple RF links can operate simultaneously. The terminal informs the network via signaling that the multi-power amplifier architecture supports the full ultra-large bandwidth or irregular bandwidth. Through this method, the terminal can send or receive signals through multiple RF links. Since these multiple RF links cover different frequency ranges within the same frequency band, the design of multiple links achieves coverage of a larger bandwidth frequency band. This allows the terminal to send or receive signals on a larger bandwidth frequency band without needing to use a costly full-bandwidth duplexer to support transmission on a large bandwidth frequency band, thereby reducing design costs and improving communication performance.

[0084] In some embodiments of this application, when the terminal supports joint demodulation or transmission of overlapping frequencies, the first signaling further includes at least one of the following:

[0085] Among the M radio frequency links of the terminal, the frequency ranges that overlap between the frequency ranges covered by adjacent radio frequency links;

[0086] The terminal's transmit capability information in overlapping frequency ranges includes at least one of the following: supported power levels, whether transmit diversity is supported, and whether UL MIMO is supported.

[0087] It should be noted that the terminal's support for joint demodulation or transmission of overlapping frequencies means that the terminal supports processing or transmitting multiple overlapping frequency signals at the same time.

[0088] It should be noted that two adjacent radio frequency links refer to two independent radio frequency transmission channels that are close to each other in the spectrum. Adjacent means that these two radio frequency links are close or related in terms of spectrum resources.

[0089] For example, for multiple adjacent radio frequency links, the terminal can report the overlapping frequency ranges between the multiple radio frequency links and the terminal's radio frequency capabilities to the network-side device. For instance, for two radio frequency links whose covered frequency ranges overlap, the terminal can report the overlapping frequency ranges of these two radio frequency links to the network-side device, so that the network-side device can instruct the terminal on the signal transmission and reception method within the overlapping frequency range based on the terminal's radio frequency capabilities.

[0090] In some embodiments of this application, when the terminal does not support joint demodulation or transmission of overlapping frequencies, the first signaling further includes at least one of the following:

[0091] The first frequency information is the frequency information of the frequency separation point or frequency separation area of ​​the frequency range covered by adjacent radio frequency links in the M radio frequency links of the terminal.

[0092] The second frequency information is the frequency range affected by the filter bandwidth edge of the filter, which includes filters in the duplexers of each RF link, or bandpass filters in each RF link.

[0093] It should be noted that the frequency boundary point refers to the dividing point in the spectrum where multiple adjacent (such as two) radio frequency links are divided into their respective frequency ranges, and the frequency separation area refers to the dividing area in the frequency band where multiple adjacent radio frequency links are divided into their respective frequency ranges.

[0094] Furthermore, a frequency dividing point can correspond to a frequency point or a frequency range, and a frequency dividing region can correspond to a frequency point or a frequency range.

[0095] It should be noted that the frequency dividing points mentioned above can also be called frequency boundary points, and similarly, the frequency dividing regions can also be called frequency boundary regions.

[0096] For example, if the terminal does not support joint demodulation or transmission of the baseband for overlapping frequency ranges, the terminal can report at least one of the frequency boundary points of the two duplexer transmit and receive signals and the frequency range affected by the filter bandwidth edge, so that the network-side device can decide the signal transmission and reception mode of the terminal at the frequency boundary point or the frequency range affected by the filter bandwidth edge based on the terminal's capabilities.

[0097] In some embodiments of this application, the M radio frequency links include X first radio frequency links and Y second radio frequency links; the X first radio frequency links cover X frequency ranges in the first frequency band, and the Y second radio frequency links cover Y frequency ranges in the first frequency band, where X and Y are integers greater than 1 and less than M.

[0098] In some embodiments of this application, at least one of the X first radio frequency links and at least one of the Y second radio frequency links cover the entire frequency range of the first frequency band, and the radio frequency links other than at least one of the X first radio frequency links and the radio frequency links other than at least one of the Y second radio frequency links cover the entire frequency range of the first frequency band.

[0099] In some embodiments of this application, the target radio frequency link among the Y second radio frequency links covers a first frequency range between adjacent first radio frequency links. The first frequency range includes the frequencies of the frequency separation points or frequency separation regions of the frequency ranges covered by the adjacent first radio frequency links, or includes the frequency range affected by the filtering bandwidth edge of the filter of the first radio frequency link.

[0100] In some embodiments of this application, by having each of the M radio frequency links cover a frequency range in the first frequency band, continuous and complete 100% repeatable coverage of the first frequency band can be achieved. Furthermore, the M radio frequency links can achieve interleaved support for the first frequency band, that is, the newly added radio frequency links cover the frequency ranges that were not originally covered between multiple (such as two) radio frequency links, thereby improving the utilization rate of the spectrum.

[0101] Figure 3 This is a schematic diagram illustrating the frequency range coverage of the radio frequency link provided in the embodiments of this application, as shown below. Figure 3As shown, the above M radio frequency links include radio frequency links 1 to 8. Among them, radio frequency links 1, 3, 6, and 8 can be existing radio frequency links, and radio frequency links 2, 4, 5, and 7 can be newly added radio frequency links. Radio frequency links 1 to 8 respectively cover the frequency range 1 to the frequency range 8 within the first frequency band. Radio frequency links 1, 3, 6, and 8 and radio frequency links 2, 4, 5, and 7 alternately cover part of the frequency range within the first frequency band. There is a certain frequency overlap range between each pair of alternately covered frequency links, and radio frequency links 1 to 8 together achieve overlapping coverage of the first frequency band.

[0102] It should be noted that one radio frequency link can cover a frequency range. For example, radio frequency link 1 covers frequency range 1, and radio frequency link 2 covers frequency range 2.

[0103] It should be noted that, Figure 3 One type of padding represents a frequency range.

[0104] In this embodiment, the terminal's radio frequency links include X existing radio frequency links and Y newly added radio frequency links. Each radio frequency link is designed to cover a specific frequency range within the first frequency band, and these ranges overlap to a certain extent. Specifically, the four existing radio frequency links and the four newly added radio frequency links cover a portion of the frequency range within the first frequency band in an interleaved manner, ensuring full utilization of frequency resources. Furthermore, there is a specific frequency overlap area between each interleaved radio frequency link, thereby further improving the utilization rate of the spectrum. In addition, through the collaborative work of these multiple radio frequency links, full coverage and overlapping coverage of the first frequency band are achieved, thereby enhancing the performance and capacity of the communication system.

[0105] In some embodiments of this application, the M radio frequency links include a third radio frequency link and a fourth radio frequency link. The third radio frequency link includes a first power amplifier and a first duplexer, and the fourth radio frequency link includes a second power amplifier and a second duplexer. Exemplarily, step 201 may include the following step 201a.

[0106] Step 201a: The terminal transmits or receives signals in the first frequency range through the third radio frequency link, and transmits or receives signals in the second frequency range through the fourth radio frequency link.

[0107] The first frequency range and the second frequency range together constitute the entire frequency range of the target frequency band, and there is at least partial overlap between the first frequency range and the second frequency range.

[0108] For example, the target frequency band mentioned above can be N28. For an explanation of N28, please refer to the description above, which will not be repeated here.

[0109] For example, when the terminal transmits a signal in the first frequency range via the third radio frequency link, i.e. when the first frequency range is used for uplink transmission, the first frequency range can be 703MHz-733MHz within N28; or, when the terminal receives a signal in the first frequency range via the third radio frequency link, i.e. when the first frequency range is used for downlink transmission, the first frequency range can be 758MHz-788MHz within N28.

[0110] For example, when the terminal transmits a signal in a second frequency range via the fourth radio frequency link, the second frequency range may be 718MHz-748MHz within N28; or, when the terminal receives a signal in a second frequency range via the fourth radio frequency link, the first frequency range may be 778MHz-803MHz within N28.

[0111] For example, when the target frequency band is N28, the overlapping frequency range between the first frequency range and the second frequency range can be 718MHz-733MHz, or the overlapping frequency range between the first frequency range and the second frequency range can be 718MHz-733MHz.

[0112] It should be noted that for frequency band 28, the third and fourth radio frequency links can jointly cover the entire uplink frequency range or the entire downlink frequency range of frequency band 28, and there is a certain overlap in frequency range between the third and fourth radio frequency links.

[0113] In this embodiment, for frequency band 28, the terminal adopts a dual power amplifier architecture with two duplexers. A new reporting signaling is added: In the dual power amplifier architecture, one set of power amplifiers corresponds to one duplexer (corresponding to one RF link), and both sets of power amplifiers can operate simultaneously. A single duplexer has a bandwidth of 30MHz, and the superposition of the two duplexers achieves bandwidth support greater than 30MHz while also being compatible with NS_17 radiation protection. Currently, the available bandwidth for frequency band 28 is 45MHz. The two duplexers support 30MHz of transmit and receive, with a 15MHz overlap. The terminal reports the overlapping frequency range to indicate stronger transmit capabilities in that frequency range, including but not limited to higher power levels, transmit diversity, or UL MIMO. Furthermore, if the terminal does not support joint demodulation of the overlapping frequency range by the baseband, the terminal can report the frequency boundary points of the two duplexers' transmit and receive operations, and the frequency range affected by the filter bandwidth edge, so that the network-side equipment can make reasonable decisions based on the information reported by the terminal, thereby improving communication performance.

[0114] In some embodiments of this application, the above-mentioned M radio frequency links further include a fifth radio frequency link and a sixth radio frequency link.

[0115] The third radio frequency link covers the first frequency range in the target frequency band, the fourth radio frequency link covers the second frequency range in the target frequency band, the fifth radio frequency link covers the third frequency range in the target frequency band, and the sixth radio frequency link covers the fourth frequency range in the target frequency band.

[0116] In some embodiments of this application, the first frequency range and the third frequency range together constitute the entire frequency range of the target frequency band, and the second frequency range and the fourth frequency range together constitute the entire frequency range of the target frequency band.

[0117] For example, when the terminal transmits a signal in the third frequency range through the fifth radio frequency link, that is, when the third frequency range is used for uplink transmission, the third frequency range can be 733MHz-748MHz within N28; or, when the terminal receives a signal in the third frequency range through the fifth radio frequency link, that is, when the third frequency range is used for downlink transmission, the third frequency range can be 788MHz-803MHz within N28.

[0118] For example, when the terminal transmits a signal in a fourth frequency range via the sixth radio frequency link, the fourth frequency range may be 703MHz-718MHz within N28; or, when the terminal receives a signal in a fourth frequency range via the sixth radio frequency link, the first frequency range may be 758MHz-773MHz within N28.

[0119] Figure 4 This is a schematic diagram illustrating the frequency range coverage of the radio frequency link provided in the embodiments of this application, as shown below. Figure 4 As shown in (A), the M radio frequency links include radio frequency link 11 and radio frequency link 12. Radio frequency link 11 covers 703MHz-733MHz within N28, and radio frequency link 12 covers 718MHz-748MHz within N28. The two radio frequency links have a 15MHz overlap in coverage area. Figure 4 As shown in (B), the M RF links can also include RF link 13 and RF link 14. RF link 13 covers 733MHz-748MHz within N28, and RF link 14 covers 703MHz-718MHz within N28. Among them, there is a 15MHz overlap frequency range between RF link 11 and RF link 12. The frequency range covered by RF link 11 and the frequency range covered by RF link 13 constitute the complete uplink frequency band of N28, and the frequency range covered by RF link 12 and the frequency range covered by RF link 14 also constitute the complete uplink frequency band of N28. RF links 11, RF link 12, RF link 13 and RF link 14 together achieve overlapping coverage of the uplink frequency band of N28.

[0120] It should be noted that for frequency band 28, the first frequency range and the third frequency range together constitute the complete uplink or downlink frequency band of frequency band N28, and the second frequency range and the fourth frequency range together constitute the complete uplink or downlink frequency band of frequency band N28. The third radio frequency link and the fifth radio frequency link can jointly cover the entire uplink frequency range or the entire downlink frequency range of frequency band 28, and the fourth radio frequency link and the sixth radio frequency link can jointly cover the entire uplink frequency range or the entire downlink frequency range of frequency band 28. Thus, through four radio frequency links, the complete uplink frequency band or the complete downlink frequency band of frequency band 28 is repeatedly covered.

[0121] In some embodiments of this application, the third, fourth, fifth, and sixth radio frequency links described above are used for transmit diversity, UL MIMO, or receive diversity in the target frequency band.

[0122] In this embodiment, the terminal adds a new radio frequency link to cover the remaining frequency bands in the N28 band, thereby completing the repeated coverage of the entire frequency band, so as to realize transmit diversity, ULMIMO, receive diversity, power, and power level across the entire bandwidth, thereby improving the utilization of the spectrum.

[0123] In some embodiments of this application, the communication method provided in this application further includes the following step 203:

[0124] Step 203: The terminal adjusts its capability indicators based on the first information.

[0125] The first piece of information is used to indicate a reduction in performance requirements for the terminal's capability metrics.

[0126] In some embodiments of this application, the aforementioned capability indicators include at least one of the following: receiver sensitivity, maximum sensitivity degradation (MSD), and error vector magnitude (EVM).

[0127] In some embodiments of this application, the first information may be information sent by the network-side device, information predefined by the terminal, or information agreed upon by the protocol.

[0128] It should be noted that in a multi-RF link environment, the terminal may experience interference from different directions and frequency bands.

[0129] In this embodiment, the terminal side introduces relaxed capability indicators for the transmitting end (Tx) and / or the receiving end (Rx). By adjusting capability indicators such as receiver sensitivity, maximum sensitivity degradation (MSD), and error vector magnitude (EVM), the terminal can more flexibly adapt to different network environments and usage scenarios. In this way, by adjusting relevant capability indicators, such as reducing the EVM requirement, signal quality degradation and communication interruption caused by interference are reduced, thereby ensuring the stability and performance of the terminal's communication.

[0130] Figure 5 Another flowchart illustrating the communication method provided in this application embodiment is shown below. Figure 5 As shown, the communication method may include the following steps 301 and 302:

[0131] Step 301: The terminal sends the first signaling to the network-side device.

[0132] Step 302: The network-side device receives the first signaling sent by the terminal.

[0133] The first signaling message contains information about the frequency range covered by the terminal's radio frequency link and / or the terminal's operating mode information on the radio frequency link.

[0134] It should be noted that the explanation of steps 301 and 302 can be found in the description of the above terminal-side method embodiments, and will not be repeated here.

[0135] In some embodiments of this application, when the terminal supports joint demodulation or transmission of overlapping frequencies, the first signaling further includes at least one of the following:

[0136] Information on the overlapping frequency ranges between adjacent radio frequency links in the terminal's M radio frequency links, where M is an integer greater than 1;

[0137] The terminal's transmit capability in the overlapping frequency range, the transmit capability including at least one of power level, transmit diversity, and uplink UL multiple-input multiple-output MIMO.

[0138] In some embodiments of this application, the communication method provided in this application may further include the following step 302:

[0139] Step 302: The network-side device performs at least one of the following actions according to the first signaling:

[0140] Increase the terminal's transmission power within the overlapping frequency range;

[0141] Increase the number of terminal scheduling attempts within overlapping frequency ranges;

[0142] Reduce coding redundancy in terminals within overlapping frequency ranges;

[0143] Increase the modulation order of the terminal within the overlapping frequency range;

[0144] Increase the amount of data transmitted by the terminal in the overlapping frequency range;

[0145] Increase the transmission rate of the terminal in the overlapping frequency range.

[0146] In some embodiments of this application, when the terminal supports joint demodulation or transmission of overlapping frequencies, the network-side device can perform the above-mentioned processing actions according to the first signaling reported by the terminal.

[0147] It should be noted that increasing the transmission power within the overlapping frequency range can improve signal strength, making data transmission more reliable and reducing retransmission requirements due to signal attenuation or interference, thereby improving transmission performance. Increasing the number of times the terminal schedules data within the overlapping frequency range allows for more efficient use of frequency resources, ensuring timely data transmission during critical periods. Reducing coding redundancy within the overlapping frequency range lowers bandwidth requirements without affecting correct data reception, thus improving overall communication quality. Increasing the modulation order within the overlapping frequency range allows the terminal to transmit more data within the same bandwidth, effectively utilizing the spectrum. Finally, increasing the data transmission volume and rate within the overlapping frequency range allows the terminal to make fuller use of this range, further enhancing transmission performance.

[0148] In this embodiment, the network-side device dynamically adjusts the parameters of the terminal within the overlapping frequency range, such as transmission power, scheduling times, coding redundancy, and modulation order, according to the first signaling, thereby improving the utilization efficiency of the overlapping frequency range, which in turn improves the data transmission efficiency and communication quality of the terminal within the overlapping frequency range, and thus improves the communication performance of the terminal.

[0149] In some embodiments of this application, when the terminal does not support joint demodulation or transmission of overlapping frequencies, the first signaling further includes at least one of the following:

[0150] The first frequency information is the frequency information of the frequency separation point or frequency separation area of ​​the frequency range covered by the adjacent radio frequency links in the M radio frequency links of the terminal.

[0151] The second frequency information is the frequency range affected by the filtering bandwidth edge of the filter, where the filter is a filter in a duplexer in each RF link, or a bandpass filter in each RF link.

[0152] In some embodiments of this application, the communication method provided in this application may further include the following step 303:

[0153] Step 303: The network-side device performs at least one of the following actions according to the first signaling:

[0154] Reduce the number of times terminals are scheduled within the frequency range corresponding to the first frequency information;

[0155] Reduce the number of times terminals are scheduled within the frequency range corresponding to the first frequency information;

[0156] Increase the coding redundancy of terminals within the frequency range corresponding to the first frequency information;

[0157] Increase the coding redundancy of the terminal within the frequency range corresponding to the second frequency information;

[0158] Increase the modulation order of the terminal within the frequency range corresponding to the first frequency information;

[0159] Increase the modulation order of the terminal within the frequency range corresponding to the second frequency information;

[0160] Increase the signal demodulation threshold of the terminal within the frequency range corresponding to the first frequency information.

[0161] For example, the above-mentioned signal demodulation threshold may include the demodulated signal-to-noise ratio (SNR) threshold, the demodulated signal-to-interference plus noise ratio (SINR) threshold, the demodulated reference signal received power (RSRP) threshold, etc.

[0162] It should be noted that the signal demodulation threshold can also be other feasible demodulation thresholds, and the embodiments of this application do not limit this.

[0163] In some embodiments of this application, when the terminal does not support joint demodulation or transmission of overlapping frequencies, the network-side device can perform the above-mentioned processing actions based on the first signaling reported by the terminal.

[0164] It should be noted that for overlapping frequency ranges where the terminal does not support joint demodulation or transmission (such as the range corresponding to the first frequency information), congestion in that frequency band can be avoided by reducing the number of terminal scheduling operations; by adding coding redundancy within the frequency range corresponding to the first or second frequency information, the terminal can recover the original information through decoding even if some data is lost or damaged during transmission, thereby reducing the transmission error rate; by increasing the modulation order to match the terminal's demodulation capability, the terminal can stably receive and transmit data; and by increasing the terminal's signal demodulation threshold within the frequency range, the terminal needs a stronger signal to successfully demodulate data, thereby reducing demodulation failures caused by poor signal and improving the reliability of data transmission.

[0165] In this embodiment, the network-side device optimizes the communication performance of the terminal in different frequency ranges by reducing the number of scheduling operations, increasing coding redundancy, adjusting the modulation order, and raising the signal demodulation threshold, so as to ensure communication quality, reliability, and efficiency, even when the terminal does not support joint demodulation or transmission on overlapping frequencies.

[0166] It should be noted that other explanations and descriptions of this embodiment can be found in the relevant descriptions in the above terminal-side method embodiments, and will not be repeated here.

[0180] In some embodiments of this application, the M radio frequency links include X first radio frequency links and Y second radio frequency links;

[0181] X first radio frequency links cover X frequency ranges in the first frequency band, and Y second radio frequency links cover Y frequency ranges in the first frequency band, where X and Y are integers greater than 1 and less than M;

[0183] The target radio frequency link in the Y second radio frequency links covers a first frequency range between adjacent first radio frequency links. The first frequency range includes the frequencies of the frequency separation points or frequency separation regions of the frequency ranges covered by adjacent first radio frequency links, or includes the frequency range affected by the filtering bandwidth edge of the filter of the first radio frequency link.

[0184] In some embodiments of this application, the M radio frequency links include a third radio frequency link and a fourth radio frequency link, the third radio frequency link includes a first power amplifier and a first duplexer, and the fourth radio frequency link includes a second power amplifier and a second duplexer;

[0185] The radio frequency module is specifically used to transmit or receive signals in a first frequency range via a third radio frequency link, and to transmit or receive signals in a second frequency range via a fourth radio frequency link.

[0186] The first frequency range and the second frequency range together constitute the entire frequency range of the target frequency band, and there is at least partial overlap between the first frequency range and the second frequency range.

Different RF links are used to transmit or receive signals at different frequency ranges within the same frequency band, where M is an integer greater than 1. Through this method, the communication device can transmit or receive signals through multiple RF links. Since these multiple RF links cover different frequency ranges within the same frequency band, a wider bandwidth frequency band is covered by designing multiple links. This allows the terminal to transmit or receive signals on a wider bandwidth frequency band without needing to use a costly full-bandwidth duplexer to support transmission on a large bandwidth frequency band, thereby reducing design costs and improving communication performance.
