Abstract
Description
Technical Field
[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for transmitting interference offset information. Background Technology
[0002] In some wireless communication systems, such as 4G or 5G, multi-carrier technology is used to improve transmission rate and system capacity. However, when multi-carrier transmission is implemented by combining certain frequency bands, there may be potential self-interference problems.
[0003] Given a fixed frequency band, the magnitude of self-interference is usually related to the uplink transmit power. The higher the transmit power, the greater the self-interference, and consequently, the greater the downlink sensitivity loss.
[0004] To ensure the performance of carrier aggregation, the sensitivity loss under worst-case conditions is usually specified, such as the maximum sensitivity degradation (MSD). For example, the 3GPP 101 series of standards defines the minimum MSD requirements for different frequency band combinations.
[0005] For some frequency band combinations, the MSD may exceed 30dB. When deploying these frequency band combinations, operators can adopt a method that completely prohibits terminals within the cell from configuring multi-carrier mode. However, this will prevent some terminals that can be configured to use multi-carrier mode from doing so (such as some terminals with good MSD performance or terminals located in the center of the cell, which have lower transmit power and therefore less actual sensitivity loss, thus making it impossible to use multi-carrier technology to improve data rate and system capacity). Alternatively, operators can adopt a method that allows multi-carrier mode configuration. However, when some terminals with greater sensitivity loss operate in multi-carrier mode, it will also cause a loss in system performance.
[0006] How to reduce self-interference in multi-carrier modes is a technical problem that needs to be solved. Summary of the Invention

[0052] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.
[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure.

These terms are only used to distinguish information of the same type from one another.

Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.
[0056] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0057] like Figure 1 As shown, the method for transmitting interference offset information provided in this embodiment can be applied to a wireless communication system 100, which may include, but is not limited to, a network device 101 and a user equipment 102. The user equipment 102 is configured to support carrier aggregation, and the user equipment 102 can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.
[0058] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.
[0059] The user equipment 102 shown above can be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or user equipment, etc. This user equipment 102 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices 101 of one or more communication systems, and to receive network services provided by the network devices 101, including but not limited to the base station shown in the figure.
[0060] User equipment 102 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network or user equipment in a future evolved PLMN network, etc.
[0061] Network device 101 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device may include base station (BS) equipment, or base station equipment and radio resource management equipment used to control the base station equipment. This network device may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network device can be a wearable device or an in-vehicle device. Network device can also be a communication chip with a communication module.
[0062] For example, network equipment 101 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.
[0063] To ensure the performance of carrier aggregation, it is usually stipulated that the minimum sensitivity loss (MSD) under the worst-case scenario cannot exceed a certain value. For example, the 3GPP 101 series of standards defines the minimum MSD requirements for different frequency band combinations. For some frequency band combinations, the MSD may exceed 30dB, which may cause the downlink to be completely interfered with and unable to function. The aforementioned worst-case scenario refers to the situation where the center frequency of the uplink interference signal generated by the configured resource block is exactly aligned with the center frequency of the interfered receiving channel.
[0064] Considering that the above situation is relatively rare in actual networks, since the configured resource blocks are determined based on channel quality, if the center frequency of the uplink interference signal is offset from the center frequency of the affected receiving channel, the actual sensitivity loss will be much smaller than the MSD, thereby greatly mitigating the impact of self-interference. To account for the above offset, this disclosure provides several embodiments, which are described in detail below.
[0065] The multi-carrier transmission in this disclosure can be carrier aggregation transmission or dual-link transmission. For example, dual-link is EN-DC (EUTRA-NR Dual Connection).
[0066] This disclosure provides a method for transmitting interference offset information. Figure 2 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 2 As shown, the method includes steps S201 to S202, specifically:
[0067] Step S201: The user equipment sends minimum offset information to the network device.
[0068] The minimum offset information is used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0069] In some possible implementations, the offset is the minimum offset bandwidth, or the minimum offset is the number of resource blocks corresponding to the minimum offset bandwidth.
[0070] In one example, the offset is 20MHz when the minimum offset bandwidth is used.
[0071] In one example, the minimum offset can vary depending on the multi-carrier configuration. For instance, when Band X and Band Y are combined as a multi-carrier combination, the reported minimum offset is 20MHz; while when Band X and Band Z are combined as a multi-carrier combination, the reported minimum offset is 25MHz.
[0072] In one example, the minimum offset is the number of resource blocks corresponding to the minimum offset bandwidth. For example, the number of resource blocks (RBs) corresponding to a subcarrier with a minimum offset bandwidth of 15 kHz is 100.
[0073] In step S202, the network device sends resource configuration information to the user equipment based on the received minimum offset information.
[0074] Wherein, the offset between the first center frequency point and the second center frequency point corresponding to the uplink configuration resource indicated by the resource configuration information is greater than the minimum offset, the first center frequency point is the center frequency point of the potential uplink interference signal corresponding to the uplink configuration resource, and the second center frequency point is the center frequency point of the downlink interference signal of the potential uplink interference signal.
[0075] In this embodiment of the disclosure, the user equipment sends minimum offset information to the network device to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission. Based on the received minimum offset information, the network device can determine more reasonable resource configuration information and configure uplink configuration resources for the user equipment to prevent self-interference, thereby improving the reduction of self-interference in multi-carrier transmission and improving the performance of multi-carrier transmission.
[0076] In this embodiment of the disclosure, the user equipment can actively report the minimum offset information, such as reporting the minimum offset information periodically or periodically, without the network device sending a reporting notification message.
[0077] This disclosure provides a method for transmitting interference offset information. Figure 3 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 3 As shown, the method includes:
[0078] Step S300: The network device sends a reporting notification message to the user equipment, instructing the user equipment to report the minimum offset information.
[0079] And steps S301 and S302. Steps S301 to S302 are the same as steps S201 to S202.
[0080] In this embodiment, the user equipment (UE) reports the minimum offset information only after receiving a reporting notification message from the network device; the UE does not proactively report it. Of course, the UE can also report the minimum offset information based on other triggering conditions; for example, the UE can report the minimum offset information based on triggering conditions determined by the communication protocol; or, the UE can report the minimum offset information periodically or at regular intervals; or, the UE can report the minimum offset information based on pre-stored configuration information. These triggering conditions can be various, and will not be elaborated upon here.
[0081] This disclosure provides a method for transmitting interference offset information, executed by a user equipment. Figure 4 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 4 As shown, it includes:
[0082] Step S401: Send minimum offset information to the network device. The minimum offset information is used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0083] Figure 5 A schematic diagram of minimum offset information is shown.
[0084] In some possible implementations, the minimum offset is the minimum offset bandwidth, or the minimum offset is the number of resource blocks corresponding to the minimum offset bandwidth.
[0085] In one example, the offset is the minimum offset bandwidth, for example, the minimum offset is 20MHz.
[0086] In one example, the minimum offset can vary depending on the multi-carrier configuration. For instance, when Band X and Band Y are aggregated as multi-carriers, the reported minimum offset is 20MHz; while when Band X and Band Z are aggregated as multi-carriers, the reported minimum offset is 25MHz.
[0087] In one example, the minimum offset is the number of resource blocks corresponding to the minimum offset bandwidth. For example, the number of resource blocks (RBs) corresponding to a subcarrier with a minimum offset bandwidth of 15 kHz is 100.
[0088] In some possible implementations, the minimum offset information includes the minimum offset corresponding to at least one self-interference type.
[0089] In one example, when there are multiple types of potential self-interference in a multi-carrier configuration, the minimum offset information needs to be sent in the form of an index to give the offset of different interference types, as shown in Table 1.

[0092] This disclosure provides a method for transmitting interference offset information, executed by a user equipment. Figure 6 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 6 As shown, it includes:
[0093] Step S601: Send minimum offset information to the network device. The minimum offset information is used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0094] Step S601 is the same as step S401 above.
[0095] In some possible implementations, step S602 is also included, receiving resource configuration information sent by the network device, wherein the offset between the first center frequency point and the second center frequency point corresponding to the uplink configuration resource indicated by the resource configuration information is greater than the minimum offset, the first center frequency point is the center frequency point of the potential uplink interference signal corresponding to the uplink configuration resource, and the second center frequency point is the center frequency point of the downlink interference signal of the potential uplink interference signal.
[0096] In some possible implementations, step S600 is also included, receiving a reporting notification message sent by a network device, the reporting notification message being used to indicate the reporting of the minimum offset information.
[0097] This disclosure provides a method for transmitting interference offset information, executed by a network device. Figure 7 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 7 As shown, it includes:
[0098] Step S701: Receive minimum offset information sent by the user equipment. The minimum offset information is used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0099] Step S701 is the same as step S401 above.
[0100] It also includes step S700, sending a reporting notification message to the user equipment, the reporting notification message being used to instruct the user equipment to report the minimum offset information.
[0101] This disclosure provides a method for transmitting interference offset information, executed by a network device. Figure 8 This is a flowchart illustrating a method for transmitting interference offset information according to an exemplary embodiment, such as... Figure 8 As shown, it includes:
[0102] Step S801: Receive minimum offset information sent by the user equipment. The minimum offset information is used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0103] Step S801 is the same as step S401 above.
[0104] Step S802: Send resource configuration information to the user equipment. The offset between the first center frequency point and the second center frequency point corresponding to the uplink configuration resource indicated by the resource configuration information is greater than the minimum offset. The first center frequency point is the center frequency point of the potential uplink interference signal corresponding to the uplink configuration resource, and the second center frequency point is the center frequency point of the downlink interference signal of the potential uplink interference signal.
[0105] In some possible implementations, step S801-1 further includes determining the existence of potential self-interference, determining the type of self-interference, and determining the uplink configuration resources based on the type of self-interference.
[0106] Among them, network devices determine whether there is potential self-interference in multi-carrier transmission in the following three ways:
[0107] Method 1
[0108] Based on the TR37.863 specification, it is determined whether potential self-interference exists in multi-carrier transmission according to the frequency relationship between member carriers, and when potential self-interference exists, the type of interference of potential self-interference is determined.
[0109] The interference center frequency f is calculated according to formula (1). INT :
[0110] f INT =a×f TX1 +b×f RX1 +c×f TX2 +d×f RX2 (1)
[0111] The coefficients a, b, c, and d can be obtained from the MSD table in sub-specification 7.3B.2.
[0112] The interference impact bandwidth BW is calculated according to formula (2). INT :
[0113] BW INT =a×CBW TX1 +c×CBW TX2 (2)
[0114] Wherein, CBW represents the channel bandwidth.
[0115] When formula (3) is satisfied, it is determined that the uplink interference signal falls into the frequency band of the received signal RX1, thus causing self-interference.
[0116]
[0117] When formula (4) is satisfied, it is determined that the uplink interference signal falls into the frequency band of the received signal RX2, thus causing self-interference.
[0118]
[0119] If self-interference is determined to have occurred according to formula (3) or formula (4), the type of interference can be further determined according to the coefficient in formula (1).
[0120] In one example:
[0121] If only one of a and b has a value of 0, the interference type is harmonic interference, and the order of the harmonics is determined by the coefficient with a non-zero value.
[0122] If both a and b are not 0, then it is intermodulation interference, and the order of intermodulation is the sum of the absolute values of a and b.
[0123] Method 2
[0124] Determine whether there is potential self-interference of harmonic interference type among the component carriers of a multi-carrier transmission according to the table on harmonic interference in Section 7.3A.4 of the TS38.101 standard.
[0125] Determine whether there is potential self-interference of intermodulation interference type among the component carriers of a multi-carrier transmission according to the table on intermodulation interference in Section 7.3A.5 of the TS38.101 standard.
[0126] Determine whether there is potential self-interference of the adjacent channel interference type among the component carriers of a multi-carrier transmission according to the table on adjacent channel interference in Section 7.3A.6 of the TS38.101 standard.
[0127] Method 3
[0128] Based on a custom table, determine whether there is potential self-interference between the component carriers of the multi-carrier transmission, and determine the type of interference of potential self-interference.
[0129] In one example, Table 2 is an exemplary table.
[0130] Table 2
[0131]
[0132] In some possible implementations, the network device determines the uplink configuration resources based on the self-interference type, such that the actual offset of the center frequency of the potential uplink interference signal from the downlink interference signal is greater than the minimum offset received from the user equipment.
[0133] In one example, the network device determines the type of potential self-interference and, based on that interference type, determines the uplink BWP, ensuring that the actual offset of the center frequency of the potential uplink interference signal from the interfered downlink BWP signal is greater than the minimum offset received from the user equipment. For example... Figure 9 The diagram shown is shown in the image.
[0134] Specifically, when determining the uplink configuration resources based on the self-interference type, the uplink configuration resources can be determined according to the calculation formula corresponding to the self-interference type. This calculation formula can be determined according to usage requirements.
[0135] In some possible implementations, the method further includes: step S800, sending a reporting notification message to the user equipment, the reporting notification message being used to instruct the user equipment to report the minimum offset information.
[0136] Based on the same concept as the above method embodiments, this disclosure also provides an electronic device that possesses the functions of the user device 102 in the above method embodiments and is used to execute the steps performed by the user device 102 provided in the above embodiments. This function can be implemented in hardware, or in software, or in hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.
[0137] In one possible implementation, such as Figure 10 The electronic device 1000 shown can serve as the user equipment 102 involved in the above method embodiment and perform the steps executed by the user equipment 102 in the above method embodiment.
[0138] The communication device 1000 includes a transceiver module 1001.
[0139] The transceiver module 1001 is configured to send minimum offset information to the network device, the minimum offset information being used to indicate the minimum offset between the center frequency of the uplink interference signal and the center frequency of the interfered signal in multi-carrier transmission.
[0140] In one possible implementation, the offset is the minimum offset bandwidth, or the minimum offset is the number of resource blocks corresponding to the minimum offset bandwidth.
[0141] In one possible implementation, the transceiver module 1001 is configured to receive a reporting notification message sent by the network device, the reporting notification message being used to indicate the reporting of the minimum offset information.
[0142] In one possible implementation, the transceiver module 1001 is configured to receive resource configuration information sent by the network device, wherein the offset between the first center frequency point and the second center frequency point corresponding to the uplink configuration resource indicated by the resource configuration information is greater than the minimum offset, the first center frequency point is the center frequency point of the potential uplink interference signal corresponding to the uplink configuration resource, and the second center frequency point is the center frequency point of the downlink interference signal of the potential uplink interference signal.
[0143] When the communication device is user equipment 102, its structure can also be as follows: Figure 11 As shown.
