Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method for determining and reporting the bandwidth capability of a terminal frequency band, as well as network equipment and terminals. Background Technology

[0002] 5G NR defines a series of frequency band resources and assigns a frequency band number to each frequency band to identify its range. When a terminal is camped on the network, it reports the frequency band numbers of all frequency bands supported by the terminal to the network via the UE (Terminal or User Equipment) capability report, and also reports the working bandwidth supported by the terminal for each frequency band. In existing technologies, when a terminal reports a frequency band number, the network assumes that the terminal supports the full bandwidth of that frequency band.

[0003] However, for some frequency bands, it is difficult for terminals to support the entire frequency band. For example, for the n28 frequency band (uplink 703-748MHz, downlink 758-803MHz), firstly, if the terminal supports the entire frequency band, there will be self-interference problems, and secondly, the global spectrum allocation is scattered, making it difficult to have a complete frequency band.

[0004] Regarding the first point, the n28 frequency band, as Figure 1 As shown, the uplink and downlink intervals are very short, only 10MHz, making uplink interference prone to cause self-interference. One industry solution addresses this issue by segmenting the entire frequency band. The n28 band is divided into two partially overlapping sub-bands: Sub-band A (uplink 703-733MHz, downlink 758-788MHz) and Sub-band B (uplink 718-748MHz, downlink 773-803MHz), with a 25MHz uplink / downlink interval between each segment to prevent terminal self-interference. The terminal can implement this solution using two independent filters, each corresponding to either sub-band A or sub-band B. The two filters cannot operate simultaneously; only one filter is activated during terminal operation.

[0005] Regarding the second point, the n28 band, due to its lower frequency and better coverage, is considered a golden frequency band for mobile communication and has a wide range of uses, such as broadcasting, emergency response, and cellular mobile communication. This has led to the n28 band being relatively dispersed in global 5G spectrum allocation. For example, in some regions, only sub-band A of the n28 band has been allocated, so some operators in those regions only require terminals to support sub-band A.

[0006] As mentioned above, existing technologies only define the operating bandwidth capability reported by the terminal for each frequency band. By default, the terminal supports the full bandwidth of each frequency band. However, for some frequency bands, supporting the full bandwidth is difficult, leading to various terminal types with differing bandwidth capabilities to meet the needs of different global operators. Existing technologies do not define the terminal's reported bandwidth capability, which the base station cannot know. When a terminal initiates service establishment, if the frequency band resources allocated by the base station do not match the terminal's bandwidth capability, resource allocation will fail, resulting in service establishment failure. Summary of the Invention

[0007] This invention provides a method for determining and reporting the bandwidth capability of a terminal's frequency band, as well as a network device and terminal. This enables the network to accurately allocate resources based on the terminal's frequency band bandwidth capability, avoiding resource allocation failures.

[0081] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0082] like Figure 2 As shown, an embodiment of the present invention provides a method for determining the bandwidth capability of a terminal frequency band, applied to a network device, the method comprising:

[0083] Step 21: Configure the first sub-band resource to the terminal; Optionally, the network device (such as a base station) configures the first segment of the sub-band (i.e., the first sub-band resource) to the terminal through RRC signaling, for example, through RRC reconfiguration signaling.

[0084] Step 22: Receive the terminal's response information regarding its support capability for the first sub-band;

[0085] Step 23: Determine the terminal's support capability for the first sub-band based on the terminal's response information regarding its support capability for the first sub-band.

[0086] The above embodiments of the present invention configure first sub-frequency band resources to the terminal; receive response information from the terminal regarding its support capability for the first sub-frequency band; and determine the terminal's support capability for the first sub-frequency band based on the response information. This enables the network to accurately allocate resources according to the terminal's frequency band bandwidth capability, avoiding resource allocation failures.

[0087] In an optional embodiment of the present invention, step 22 may include:

[0088] Step 221: Receive a first response message from the terminal indicating successful resource configuration. This successful resource configuration response message is sent when the terminal supports the first sub-frequency band; or...

[0089] Step 222: Receive a second response message from the terminal indicating that the resource configuration failed. The response message indicating that the resource configuration failed was sent when the terminal did not support the first sub-frequency band.

[0090] In an optional embodiment of the present invention, when receiving the first response information indicating successful resource configuration sent by the receiving terminal, step 23 may include:

[0091] Based on the first response information indicating successful resource configuration, it is determined that the terminal supports the first sub-frequency band.

[0092] In an optional embodiment of the present invention, when receiving a second response message indicating unsuccessful resource configuration from a terminal, step 23 may include: determining, based on the second response message indicating unsuccessful resource configuration, that the terminal does not support the first sub-frequency band.

[0093] In an optional embodiment of the present invention, the method for determining the terminal frequency band bandwidth capability, when it is determined that the terminal does not support the first sub-frequency band, may further include:

[0094] Step 223: Receive a Radio Resource Control (RRC) Connection Re-establishment Request message sent by the receiving terminal. The RRC Connection Re-establishment Request message carries the reason for the RRC connection reconfiguration failure.

[0095] In the above embodiments of the present invention, specific implementation includes:

[0096] 1) The base station configures the first sub-band resource. The base station configures the first segment of the sub-band to the terminal through RRC signaling, for example, through RRC reconfiguration signaling.

[0097] 2) The terminal responds based on whether it supports the first sub-band:

[0098] A. If the terminal supports the configuration issued by the base station, the response resource configuration is successful.

[0099] The base station detected that the terminal supports the first sub-band resource.

[0100] B. If the terminal does not support the configuration issued by the base station, the resource configuration will fail.

[0101] The base station detected that the terminal does not support the first sub-band resource.

[0102] According to the 3GPP protocol, the terminal will trigger the RRC connection re-establishment process at this time, and report the reason as RRC connection reconfiguration failure in the RRC connection re-establishment request message. Optionally, a new reason can also be reported: sub-band not supported.

[0103] In an optional embodiment of the present invention, the method for determining the terminal frequency band bandwidth capability may further include:

[0104] Step 24: Configure the second sub-band resources to the terminal;

[0105] Step 25: Receive the terminal's response information regarding its support capability for the second sub-band;

[0106] Step 26: Determine the terminal's support capability for the second sub-band based on the terminal's response information regarding its support capability for the second sub-band.

[0107] In an optional embodiment of the present invention, step 25 may include:

[0108] Step 251: Receive a third response message from the terminal indicating successful resource configuration. This successful resource configuration response message is sent when the terminal supports the second sub-frequency band; or...

[0109] Step 252: Receive a fourth response message from the terminal indicating that the resource configuration failed. The response message indicating that the resource configuration failed was sent when the terminal did not support the second sub-band.

[0110] In an optional embodiment of the present invention, when receiving a third response message indicating successful resource configuration from a terminal, step 26 may include:

[0111] Based on the third response information indicating successful resource configuration, it is determined that the terminal supports the second sub-frequency band.

[0112] In an optional embodiment of the present invention, when receiving a fourth response message indicating unsuccessful resource configuration from a terminal, step 26 may include:

[0113] Based on the fourth response information indicating unsuccessful resource configuration, it is determined that the terminal does not support the second sub-band.

[0114] In an optional embodiment of the present invention, the method for determining the terminal frequency band bandwidth capability may further include:

[0115] Step 27: Report the supported capabilities of the terminal's first sub-band and / or second sub-band to the core network for storage.

[0116] In this embodiment, the base station configures a second sub-band resource, and the terminal responds based on whether it supports the second sub-band, in the same manner as the first sub-band. Alternatively, the base station may configure the second sub-band resource only for scenarios where the terminal does not support the first sub-band resource, and the terminal responds based on whether it supports the second sub-band, in the same way. Optionally, the base station may send the detected terminal frequency band bandwidth capability to the core network for storage, and the core network may then send it back to the base station when the terminal re-establishes a connection.

[0117] In an optional embodiment of the present invention, the method for determining the terminal frequency band bandwidth capability may further include:

[0118] Step 28: When the terminal roams, the network equipment in the roaming location receives the frequency band bandwidth capability supported by the home terminal from the roaming core network.

[0119] Step 29: Allocate corresponding resources based on the frequency band bandwidth capabilities supported by the home terminal.

[0120] In its specific implementation, this embodiment includes:

[0121] 1) When operators sign roaming agreements, the home operator informs the roaming operator of the frequency band bandwidth capabilities supported by the home terminal, and incorporates this information into the roaming agreement;

[0122] 2) When a terminal roams, the roaming core network first confirms the home operator based on the terminal's IMSI, and then queries the roaming agreement signed with the home operator to find the frequency band bandwidth capabilities supported by the home terminal.

[0123] 3) The roaming core network will notify the roaming base station of the frequency band bandwidth capabilities supported by the home terminal;

[0124] 4) Roaming base stations allocate corresponding resources based on the terminal's frequency band bandwidth capabilities.

[0125] Specific implementation examples of the above embodiments of the present invention are as follows:

[0126] Example 1: The base station attempts to configure the detection terminal's frequency band bandwidth capability.

[0127] like Figure 3 As shown, 1) For the n28 frequency band, when the terminal initiates service establishment on this frequency band, the base station configures sub-frequency band B in the RRC connection reconfiguration request message (RRC Reconfiguration).

[0128] 2) The terminal responds based on whether it supports the first sub-band:

[0129] a. If the terminal supports sub-band B, it responds with an RRC connection reconfiguration complete message. The base station thus detects that the terminal supports sub-band B.

[0130] like Figure 4 As shown in Figure b, if the terminal does not support sub-band B, the terminal will trigger the RRC connection re-establishment process and report the reason as RRC connection reconfiguration failure in the RRC connection re-establishment request message (RRC Reconfiguration), or use the newly added reporting reason - frequency band not supported. Then the base station detects that the terminal does not support sub-band B; then RRC connection re-establishment is performed.

[0131] like Figure 5As shown, in the case of terminal response resource configuration failure, the base station receives the terminal's RRC connection re-establishment request and configures sub-band A in the RRC connection re-establishment message. If the resource configuration is successful, the terminal responds with an RRC connection re-establishment complete message, and the base station detects that the terminal supports sub-band A. The base station sends the detected terminal bandwidth capability in this band (supporting sub-band A, but not sub-band B) to the core network for storage. This information is then sent back to the base station by the core network when the terminal re-establishes a connection.

[0132] like Figure 6 As shown, embodiments of the present invention also provide a method for reporting terminal frequency band bandwidth capabilities, applied to a terminal, the method comprising:

[0133] Step 61: Report the terminal's support capability for the first sub-band and / or the second sub-band to the network device.

[0134] In this embodiment, the terminal reports the frequency band bandwidth capability in the UE capability reporting signaling or other RRC signaling. The reporting may only support the first segment of the sub-band, or only support the second segment of the sub-band, or support both the first and second segments of the sub-band, or support other segments of the sub-band.

[0135] An optional method for reporting terminal frequency band bandwidth capability according to the present invention may further include:

[0136] Step 62: Receive the resources allocated by the network device based on the terminal's support capabilities for the first and / or second sub-frequency bands. Here, the base station allocates corresponding resources based on the terminal's frequency band bandwidth capabilities. This enables the network to accurately allocate resources according to the terminal's frequency band bandwidth capabilities, avoiding resource allocation failures.

[0137] In one specific implementation embodiment, the terminal reports its frequency band bandwidth capability. For the n28 frequency band, the terminal reports the frequency band bandwidth capability in the UE capability reporting signaling. The terminal reporting may only support sub-band A, only support sub-band B, or support both sub-band A and sub-band B.

[0138] FeatureSetDownlinkPerCC::=SEQUENCE{supportedSubBandwidthENUMERATED{a,b,a&b},…}

[0139] like Figure 7 As shown, in an optional embodiment of the present invention, the method for reporting terminal frequency band bandwidth capability may include:

[0140] Step 71: Receive cell frequency band information broadcast by the cell.

[0141] Step 72: Compare the first sub-frequency band and / or the second sub-frequency band supported by the terminal with the cell frequency band information to determine the frequency band range that overlaps between the frequency band supported by the terminal and the cell frequency band;

[0142] Step 73: Report the overlapping frequency band range to the network device.

[0143] Furthermore, the method for reporting terminal frequency band bandwidth capabilities may also include:

[0144] Step 74: Receive resources scheduled by the network device for the overlapping frequency band range.

[0145] In this embodiment, the terminal receives the cell frequency band information broadcast by the cell, compares it with the frequency band supported by the terminal, and calculates the frequency band range that overlaps with the cell frequency band. The terminal reports the overlapping frequency band bandwidth capability in UE capability reporting signaling or other RRC signaling. The reported bandwidth can be a segment of a supported sub-frequency band, the center frequency point plus bandwidth of the segment, or the frequency start and end points. The base station schedules corresponding resources for the overlapping frequency band range reported by the terminal.

[0146] In this embodiment of the present invention, the specific implementation of the terminal side's ability to report overlapping frequency band bandwidth is as follows:

[0147] Assumption 1: The cell broadcasts cell frequency band information as [X, Y], and the terminal supports frequency bands [M, N], where M... <Y<N;

[0148] The terminal receives the cell frequency band information broadcast by the cell, compares it with the frequency bands supported by the terminal, and calculates the frequency band range [YM, Y] where the terminal's supported frequency bands overlap with the cell frequency bands.

[0149] The terminal reports the overlapping frequency band bandwidth capability [YM, Y] in the UE capability reporting signaling or other RRC signaling;

[0150] The base station schedules resources within the range of overlapping frequency bands reported by the terminal, within the range of [YM, Y].

[0151] Assumption 2: The cell broadcast frequency band information covers sub-bands A and B, and the terminal supports the frequency band of sub-band A;

[0152] The terminal receives the cell frequency band information broadcast by the cell, compares it with the frequency band supported by the terminal, and calculates the frequency band range that overlaps with the cell frequency band, which is sub-frequency band A.

[0153] The base station schedules resources within sub-frequency band A based on the overlapping frequency band range reported by the terminal.

[0154] like Figure 8 As shown, in an optional embodiment of the present invention, the method for reporting terminal frequency band bandwidth capability may include:

[0155] Step 81: Receive cell frequency band information broadcast by the cell.

[0156] Step 82: If there is no frequency in the cell band that the terminal does not support, the terminal selects the cell to camp on.

[0157] Step 83: If there is a frequency in the cell band that the terminal does not support, the terminal leaves the cell and searches for other cells and checks whether there is a frequency in the cell band that the terminal does not support, until a cell is found that does not have a frequency in the cell band that the terminal does not support, then the terminal stays there.

[0158] In this embodiment, the terminal checks whether the cell frequency band matches the terminal's frequency band bandwidth capability. Specifically, upon receiving the cell frequency band information broadcast by the cell, the terminal compares it with the frequency band it supports to see if the cell frequency band contains frequencies supported by the terminal. If there are no frequencies in the cell frequency band that the terminal does not support, i.e., the terminal's supported frequency band is greater than or equal to the cell frequency band, the terminal selects that cell to camp on. If there are frequencies in the cell frequency band that the terminal does not support, the terminal leaves that cell, searches for other cells, and checks whether there are frequencies in the cell frequency band that the terminal does not support, until a cell is found that does not contain frequencies that the terminal does not support, and then camps on that cell.

[0159] In an optional embodiment of the present invention, the terminal reports its frequency band bandwidth support capability in the terminal capability reporting signaling; wherein the terminal reports its support capability in different frequency ranges using different fields.

[0160] Specifically, the terminal can report its frequency band bandwidth capability by adding new terminal capability reporting signaling or by adding new fields to existing terminal capability reporting signaling to indicate the specific implementation method of the terminal on the reported frequency band:

[0161] For the different possible implementation methods of a terminal on a complete frequency band: type0 supports the entire frequency band, type1 supports a portion (or sub-band) of the complete frequency band, type2 supports a portion (or sub-band) of the complete frequency band, and so on. When the terminal reports the frequency band, different fields can be used to represent its different specific implementation methods, for example:

[0162] For the specific implementations of n41 and its possible terminals: n41 (2496-2690MHz), n41' (2515-2675MHz), n41" (2555-2655MHz), ... different newly added IE fields can be used for capability differentiation and reporting.

[0163] When the newly added field IE is 00, it means that the specific implementation method of this terminal is type0: supports the n41 full frequency band 2496-2690MHz;

[0164] When the newly added field IE is 01, it means that the specific implementation method of this terminal is type1: supporting some frequency bands of n41: 2515-2675MHz;

[0165] When the newly added field IE is 10, it means that the specific implementation method of this terminal is type2: supporting some frequency bands of n41: 2555-2655MHz.

[0166] The capability processing scheme for incomplete frequency band capability mismatch described in the above embodiments of the present invention involves the terminal reporting its frequency band bandwidth capability, or the network obtaining the terminal's frequency band bandwidth capability, so that the network can accurately allocate resources according to the terminal's frequency band bandwidth capability, avoid resource allocation failure, and improve user experience.

[0167] Embodiments of the present invention also provide a device for determining the bandwidth capability of a terminal frequency band, applied to a network device, the device comprising:

[0168] The transceiver module is used to configure the first sub-frequency band resources to the terminal and receive the terminal's response information regarding its support capability for the first sub-frequency band.

[0169] The processing module is used to determine the terminal's support capability for the first sub-frequency band based on the response information of the terminal's support capability for the first sub-frequency band.
