Description

Technical Field

[0001] This application relates to a method, apparatus, system, and computer program. Background Technology

[0002] A communication system can be viewed as a facility that enables a communication session between two or more entities (such as user terminals, base stations, and / or other nodes) by providing carrier waves between various entities involved in the communication path. The communication system can be provided, for example, through a communication network and one or more compatible communication devices. The communication session can include, for example, data communication for carrying communications such as voice, video, email, text messages, multimedia, and / or content data. Non-limiting examples of the services provided include two-way or multiplexed calls, data communication or multimedia services, and access to data network systems such as the Internet.

[0003] In wireless communication systems, at least a portion of a communication session between at least two stations occurs via a wireless link. Examples of wireless systems include Public Land Mobile Networks (PLMNs), satellite-based communication systems, and various wireless local area networks (WLANs). Some wireless systems can be divided into cells and are therefore often referred to as cellular systems.

[0004] Users can access the communication system through appropriate communication equipment or terminals. The user's communication equipment may be referred to as user equipment (UE) or user gear. The communication equipment is provided with appropriate signal receiving and transmitting means to enable communication, such as enabling access to a communication network or direct communication with other users. The communication equipment can access a carrier provided by a station (e.g., a base station in a cell) and transmit and / or receive communication on that carrier.

[0005] Communication systems and associated equipment typically operate according to a given standard or specification that outlines what the various entities associated with the system are allowed to do and how that should be implemented. The communication protocols and / or parameters used for connectivity are also usually defined. One example of a communication system is UTRAN (3G Radio). Other examples include the Long Term Evolution (LTE) of Universal Mobile Telecommunications System (UMTS) radio access technology and so-called 5G or New Radio (NR) networks.

Detailed Implementation

[0061] In the following explanation, certain embodiments are described with reference to mobile communication devices and services capable of communicating via wireless cellular systems.

[0062] Reference sensitivity can be considered as the minimum power (e.g., minimum average power) of one of one or more antenna ports applied to a user equipment (UE), at which the throughput should meet or exceed the requirements for a specified reference measurement channel.

[0063] In some communication systems, reference sensitivity relaxation is permitted as an exception. For example, in some cases, band combinations may lead to reference sensitivity degradation due to radio frequency (RF) impairments such as uplink (UL) harmonics, harmonic mixing, intermodulation (IMD), etc. A band combination can be considered as a set of at least two bands used for carrier aggregation or dual connectivity, where the corresponding frequency ranges can be: continuous; discontinuous. In some communication systems, reference sensitivity relaxation is permitted to address reference sensitivity degradation. This is discussed in 3GPP TS 38.101-1 and 3GPP TS 38.101-3. The permitted amount of relaxation is defined as the maximum sensitivity degradation (MSD).

[0064] In carrier aggregation (CA), two or more component carriers (CCs) are aggregated. A UE can receive or transmit simultaneously on one or more CCs depending on its capabilities. In dual connectivity (DC), a UE with multi-Rx / Tx capabilities can be configured to utilize resources provided by two different nodes via a non-ideal backhaul connection. In CA and / or DC operation, MSD is the amount of relaxation of the reference sensitivity allowed by the UE to address certain radio frequency (RF) impairments (such as uplink (UL) harmonics, harmonic mixing, intermodulation (IMD), etc.). A lower MSD means less relaxation of reference sensitivity is required, and therefore, network operators generally prefer a lower MSD. If a UE can report a lower MSD for its CA / DC band combination, the gNB / network can benefit from optimizing resource scheduling by differentiating the amount of the UE's MSD. MSD affects the UE's ability to receive downlink signals on carriers; if the signal level is lower than the UE's receiver's specified sensitivity level plus the amount of MSD, the UE may not be able to receive the signal correctly. MSD is currently defined in the standard requirements.

[0065] Table 1 shows the 2DL / 2UL interband reference sensitivity quadrature phase shift keying (QPSK) reference sensitivity power level (P) for power level 3 (PC3) CA. REFSENS The uplink / downlink configuration is specified in Table 7.3A.5-1 of 3GPP TS38.101-1.

[0066] Table 1 shows that when inter-band carrier aggregation of CA_n3-n78 is configured, under a certain resource configuration, a 26dB decrease in reference sensitivity is allowed for the 5MHz channel bandwidth of n3 due to IMD2. It should be noted that the reference sensitivity for the 5MHz channel bandwidth (CBW) of n3 is -97dBm for a 15kHz SCS. Therefore, for the corresponding conformance test, the UE can pass the requirement with a desired signal power level of -71dBm (-97dBm + 26dB). As described in R4-2016440, a very large MSD value effectively renders band combination useless for CA or DC feature deployment. Even if the network configures the UE with band combination, the UE may receive the n3 DL signal correctly or incorrectly due to the very large MSD. If the UE does not receive the signal correctly, time and frequency resources are wasted. Note that the 3GPP requirement is a minimum requirement; therefore, there are UEs with an MSD lower than the specified MSD or no MSD. However, even if a UE has a lower MSD value, it can be treated the same as other UEs with higher MSD values, since there is currently no network measure to distinguish between UEs with lower or higher MSD values. Therefore, it might be useful for one or more UEs to signal their MSD values ​​to the network so that the network can distinguish between UEs with lower and higher MSD values. This can be done using capability signaling from the UE to the network.

[0067]

[0068] Table 1: Interband Reference Sensitivity QPSK P for Power Level 3 (PC3) CA 2DL / 2UL REFSENS Uplink / downlink configuration The MSD capability signaling from the UE to the network discussed in the above paragraphs may result in large signaling overhead due to the number of frequency band combinations with (multiple) MSDs and the information associated with the reported MSDs (e.g., PC (power class), MSD type, MSD source order (if any), victim channel bandwidth, MSD value (threshold), etc.).

[0069] Information associated with the MSD in the report can be such as Figure 1 The structure is shown. From Figure 1 As can be seen from the tree structure, as the amount of related information increases, the amount of information required to be reported increases significantly.

[0070] against Figure 1For example, consider the CA_n3-n78 band combination. If each power level 101 reports a lower MSD capability, the signaling volume is approximately doubled because the MSD value 109 may vary depending on the power from each band. Power level 101 can be considered as the maximum output power of any transmission bandwidth within the channel bandwidth including the NR carrier. In some examples, the power level can be considered as the maximum output power achievable per band (non-CA) or per band combination (CA / DC).

[0071] like Figure 1 As shown, the report also indicates an increase in the required signaling volume for each MSD type 103. Table 1 shows the MSDs for CA_n3-n78 due to (multiple) IMDs. However, other MSD types exist, such as UL harmonics, crossband isolation, and harmonic mixing. Some band combinations have MSDs from multiple MSD types. For example, CA_n3-n78 has MSDs not only due to IMDs but also due to UL harmonics and harmonic mixing.

[0072] like Figure 1 As shown, the report also adds the required signaling amount for each MSD type level 105. For each MSD type corresponding to the cause of reference sensitivity degradation (e.g., IMD, UL harmonics, UL harmonic mixing, etc.), there are conditions under which reference sensitivity degradation occurs. In some examples, each different level of the MSD type can have corresponding different conditions and different amounts of reference sensitivity degradation. For example, different levels of IMD can occur under different conditions: IMD2, IMD3, etc. Each of these different levels can be referred to as an MSD type level. Table 1 shows the MSDs caused by (multiple) IMDs for CA_n3-n78, where IMD2, IMD4, and IMD7 are defined, and the MSDs are different for each MSD type level.

[0073] Although the examples in the above paragraphs pertain to (multiple) IMDs, other MSD types, such as harmonic mixers, can also have MSD type orders, such as UL1 / DL2, UL1 / DL3, UL3 / DL2, etc. For integers X and Y in ULX / DLY, this means X*f UL =Y*f DL For example, CA_n12-n77 has UL1 / DL5, where the n12 DL frequency range is 729-746 MHz. 5*(729-746) = 3645-3730 MHz, while the n77 frequency range (TDD) is 3300-4200 MHz. Therefore, there is overlap, where 1*f UL =5*f DL .

[0074] Therefore, the reference sensitivity of DL is degraded due to the harmonic mixing order of UL1 / DL5.

[0075] Depending on the MSD level for the IMD, the measures taken by the network may differ. For example, if the network considers power from two frequency bands, the impact of Tx power in each band is theoretically the same in the case of IMD2, while in the case of IMD4, such as f1+3*f2, the Tx power of the band at frequency f2 has a greater impact on the MSD. Therefore, it is useful for the UE to report the MSD value 109 and the IMD level.

[0076] like Figure 1 As shown, the MSD reported with associated victim band information 107 also increases the required signaling volume. A victim band can be considered to include bands that suffer RF damage, for example, due to CA communication, DC communication, etc. For CA_n3-n78, MSDs caused by (multiple) IMDs always affect n3 DL because this is Frequency Division Duplex (FDD) + Time Division Duplex (TDD), and therefore does not affect n78 DL during simultaneous UL. However, this is not always the case for other CA band combinations. For example, for CA_n25-n66 (FDD+FDD), as shown in Table 2, the same IMD3 can affect either n25 DL or n66 DL, depending on the composition ratio of the n25 and n66 frequencies, for example, as shown in Table 3 |2f 25 + / -f 66 |or|f 25 + / -2f 66 |

[0077]

[0078] Table 2: Information on CA_n25-n66 frequency band combinations

[0079] Table 3: Information on the CA_n25-n66 frequency band combinations Information about the victimized frequency band associated with the MSD value reported from the UE is useful for the MSD value of the network utilization report.

[0080] In some examples, the UE's MSD value can be indicated to the network by the UE reporting its specific MSD value. In other examples, the UE's MSD value can be indicated to the network by the UE reporting the range of MSD values ​​to which its MSD value falls. In some examples, the range of MSD values ​​to which the UE's MSD value falls can be indicated by an "MSD level," where the MSD level is related to a specific range of MSD values.

[0081] Table 4 shows examples of how MSD levels can be defined relative to an MSD range. Each MSD level can be indicated by a specific combination of bits sent from the UE to the network. It should be noted that these values ​​are merely examples.

[0082]

[0083] Table 4: MSD Levels and Related Information The MSD threshold can be a possible value or a range of values ​​to be reported by the UE, such as the MSD value per MSD type level per MSD type per victim channel bandwidth per power class (PC) per frequency band combination.

[0084] To reduce signaling overhead from the UE to the network, MSD reports can be filtered by network queries. For example, by a set of frequency band combinations, victim bands, or MSD types, the UE can be sent a request for the MSD value or MSD level (indicating the range of MSD values) for each victim channel bandwidth for each PC of each MSD type in each frequency band combination, and the UE can signal a lower MSD capability that meets (multiple) specified conditions.

[0085] For example, when a UE reports the MSD value or MSD level for each MSD type level (source) in its UE capability signaling, as shown in Table 1, if the UE can have an MSD value at least lower than the corresponding specified MSD value in the specification, then the UE reports the MSD value or MSD level requested by the network for each band combination (CA_n3-n78 and CA_n25-n66 in Table 1). This excludes band combinations that the network does not support, but it does not prevent the UE from reporting all MSD values ​​or MSD levels for a given band combination requested by the network. The MSD filtering discussed in the above paragraphs can reduce signaling to some extent. However, some reported MSD values ​​or MSD levels may still be inapplicable to the network and useless to the network because different networks will have different allocated spectrum ranges in the band. For example, different operators may be allocated different frequency ranges, so the network corresponding to the operator will only operate within the allocated frequency range. When the network does not operate across the entire spectrum of the frequency band, the UE may report MSD values ​​or MSD levels and associated MSD information to the network for frequency ranges not allocated to the network, which unnecessarily increases signaling overhead. Therefore, some reported MSD values ​​or MSD levels and associated MSD information are useless to the network.

[0086] exist Figure 2 An example of IMD3 considering CA_n25-n66 is shown.

[0087] As shown in Table 2, the frequency range for the DL n25 band is 1930 MHz to 1995 MHz. Figure 2 As shown in 215. The UL frequency range for the n25 band is 1850 MHz to 1915 MHz, as shown in 213, and the UL frequency range for the n66 band is 1710 MHz to 1780 MHz, as shown in 211. One of the formulas for IMD3 for CA_n25-n66 is 2*f 25 -f 66 Therefore, the check is performed due to 2*f 25 -f 66 The condition for whether the resulting IMD3 falls into n25 DL is: 1930≤2*f 25 -f 66 ≤1995, where 1850≤f 25 ≤1915 and 1710≤f 66 ≤1780(1) For the DL n25 band, the frequency range is 2110 MHz to 2200 MHz, such as Figure 2 As shown in 217. Therefore, the check is performed due to 2*f 25 -f 66 The condition for whether an IMD3 falls into n25DL is: 2110≤2*f 25 -f 66 ≤2200, where 1850≤f 25 ≤1915 and 1710≤f 66 ≤1780(2) Based on the above formula, we can obtain its 2*f 25 -f 66 (That is, the frequency range of the effect of the product of CA_n26-n66 IMD3 on n25DL or n66DL, such as...) Figure 3 As shown.

[0088] exist Figure 2 In the examples, the frequencies used by the example network for each frequency band are shown in shaded areas. The frequencies used may differ in other example networks and may be at the bottom, middle, or higher end of each frequency band (in...). Figure 2 In the example, the frequencies used are at the higher end of each frequency band, but it should be understood that this is just an example.

[0089] exist Figure 2In the examples: the frequency range used by network operators for the n66 UL band is 1750 MHz to 1780 MHz; the frequency range used by network operators for the n25 UL band is 1890 MHz to 1915 MHz; the frequency range used by network operators for the n25 DL band is 1970 MHz to 1995 MHz; and the frequency range used by network operators for the n66 DL band is 2150 MHz to 2200 MHz.

[0090] Know Figure 2 The spectrum holdings of the operators in the example can be modified according to formulas (1) and (2) respectively.

[0091] 1970≤2*f 25 -f 66 ≤1995, where 1890≤f 25 ≤1915 and 1750≤f 66 ≤1780(1)' 2150≤2*f 25 - f66 ≤2200, where 1890≤f 25 ≤1915 and 1750≤f 66 ≤1780(2)' Regarding (1), the leftmost expression can be divided into two formulas: f 66 ≤2*f 25 -1970 (1-1)' f 66 ≥2*f 25 -1995 (1-2)' If we take f 25 If the minimum frequency is placed in (1-1)' and (1-2)', then f 66 ≤2*1890-1970=1810, f 66 ≥2*1890-1995=1785. Both are greater than f. 66 UL frequency.

[0092] Regarding (2), the leftmost expression can also be divided into two formulas: f 66 ≤2*f 25 -2150 (2-1)' f 66 ≥2*f 25 -2200(2-2)' If we take f 25 The maximum frequency is placed in (2-1)' and (2-2)', f 66≤2*1915-2150=1680, f 66 ≥2*1915-2200=1630. Both are less than f. 66 UL frequency.

[0093] From the above, we can deduce that there is no frequency range that satisfies (1)' and (2)'. Therefore, we can know that IMD3(2*f 25 -f 66 The product has no IMD3 effect on n25 DL and n66 DL.

[0094] The above can also be determined by representing (1) and (2) in graphical form, as shown below. Figure 4 and 5 As shown. From Figure 4 It can be seen that as long as the n25 UL frequency is higher than 1887.5 MHz, it does not overlap with the area enclosed by the thick line. From Figure 5 It can be seen that as long as the frequency of n66UL is higher than 1720 MHz, it does not overlap with the area enclosed by the thick line.

[0095] In this way, if the UE can obtain the exact available frequency range of the corresponding frequency bands available in the network in advance, the UE can immediately determine which victim frequency bands have MSDs for each MSD type level of each MSD type in each frequency band combination.

[0096] The example provides a method for informing the UE of the exact frequency range available for the corresponding frequency bands under the network before signaling UE capabilities. If the UE can have an MSD value that is at least lower than the corresponding specified MSD value in the specification, the UE determines which victim bands of each MSD type and each MSD type order of each frequency band combination have the network-based MSD and can signal the associated lower MSD capabilities accordingly.

[0097] Figure 6 A method for MSD reporting is illustrated. At 625, network 623 (e.g., base station, gNB, etc.) sends a capability query to UE 621. In some examples, the capability query can be broadcast from network 623. The capability query may include information defining the frequency range(s) operated by network 623. In some examples, this information can be defined for each operating band in network 623. Each operating band can be considered to include the bands involved in CA and / or DC communications.

[0098] In other examples, network 623 may not be able to utilize the reported MSD value or the graded MSD level and associated MSD information, or may not need the report at all; for example, network 623 may confirm that there are no MSD issues under the network. In such an example, the network at 625 may notify UE 621 that it is rejecting the MSD report at 625. In such an example, the UE may not send any MSD information at 627.

[0099] In other examples, network 623 may not be able to perform this capability query, which would otherwise be sent at 625. In such an example, the UE can send all the MSD information it possesses at 627.

[0100] For example, network 623 may define that when a network operator has less than the entire operating frequency band allocated, it uses less than the entire operating frequency band for the UE. In other examples, network 623 may indicate a frequency band to UE 621 without indicating a frequency range less than the entire operating frequency band. In such a case, UE 621 will assume that network 623 can use the entire operating frequency band for which no restrictions are provided.

[0101] In some examples, a capability query sent at 625 may include a list of frequency bands of interest to network 625. Network 625 may list frequency bands with no frequency restrictions whatsoever. Network 625 may list frequency bands, each with its own frequency restrictions. B-3: Network 625 may list frequency bands with only frequency restrictions.

[0102] At 627, UE 621 reports UE capability information to network 623. Capability information may include MSD values ​​or MSD levels (indicating a range of MSD values) for multiple frequency ranges operated by network 623. In some examples, MSD values ​​or MSD levels are typically reported for each of the multiple frequency ranges operated by network 623. In some examples, MSD values ​​or MSD levels may be reported for each of at least one of the following characteristics in the multiple frequency ranges operated by network 623: for each victim band; for each MSD source order; for each MSD type; for each band combination. In some examples, MSD values ​​or MSD levels may be reported based on combinations of two or more different characteristics. In some examples, MSD values ​​or MSD levels may be reported based on combinations of all four characteristics, such that the MSD values ​​or ranges in the multiple frequency ranges operated by network 623 are reported for each victim band for each MSD source order of each MSD type for each band combination.

[0103] As a non-limiting example, MSD values ​​or MSD levels for (multiple) frequency ranges operated by network 623 can be reported in at least one of the following ways: For each affected frequency band; For each MSD type level; For each MSD type; For each affected frequency band, for each MSD type of each MSD type level of each frequency band combination.

[0104] For each power level of each frequency band combination, for each MSD type of each MSD type level, for each victim frequency band.

[0105] Before sending the message at 627, UE 621 determines a set of lower MSD capabilities to be transmitted for (multiple) frequency bands based on information describing the frequency ranges(s) operated by network 623. Assuming network 623 does not use the entire frequency range of each of the (multiple) operating frequency bands(s), the determined set of frequencies is smaller than the set of all (multiple) operating frequency bands(s). This minimizes the overhead signaling required at 627, especially when considering examples of reporting lower MSD capabilities for multiple combinations of characteristics of the frequency ranges used by network 623.

[0106] The message transmitted at 625 may include an information field to indicate to UE 621 the available frequency range for each supported frequency band included in the message. The information field may include a lowerEdgeDL / UL indicating the lower edge of the available frequency range for DL ​​and UL individually, and may also include an upperEdgeDL / UL indicating the upper edge of the available frequency range for DL ​​and UL.

[0107] UE 621 may store information (e.g., a lookup table) defining relationships between MSDs, victim bands, MSD types, etc. UE 621 may use this to determine information associated with MSD values. UE 621 may use information indicated by network 623 to filter (multiple) related MSDs for provision to network 623.

[0108] Figure 7 Examples of frequency bands are shown. FDD UL band 731, FDD DL band 733, and TDD band 735 are shown. The shaded portion of each band indicates the frequency range operated by the network operator. Each shaded portion has a lower edge and an upper edge indicating the lower edge and upper edge of the available frequency range, respectively. These lower EdgeDL / UL and upper EdgeDL / UL values ​​can be provided to the UE to define the frequency range operated by the network operator.

[0109] Figure 8 This illustrates an example of a single frequency band (DL band 837 in this example) having multiple frequency ranges for a given band in the case of non-contiguous spectrum allocation. This could occur when an operator is allocated two portions of the spectrum within an operating band. In such an example, a single frequency band has more than one lower EdgeDL value and more than one upper EdgeDL value.

[0110] The following considers examples of messages that may include Information Elements (IEs) in messages transmitted between network 623 and UE 621. It should be understood that these are merely illustrative examples, and messages with other structures and IEs with other structures may be transmitted at 625 and 627. Based on some examples, in Figure 6 The message sent at point 625 includes a UECapabilityEnquiry message for requesting UE radio access capabilities for NR and other RATs. This message can be sent using signaling radio bearer 1 (SRB1), RLC-SAP: AM; logical channel: DCCH, and in the direction from network 623 to UE 621.

[0111] Based on some examples, the UECapabilityEnquiry message can have the following structure:

[0112] The information element (IE) UE-CapabilityRAT-RequestList is used to request UE capabilities for one or more RATs from the UE. Below is a sample structure for the UE-CapabilityRAT-RequestList IE.

[0113]

[0114] The capabilityRequestFilter contains information that the network uses to request the UE to filter UE capabilities. For rat-Type set to nr or eutra-nr: the encoding of the capabilityRequestFilter is defined in UE-CapabilityRequestFilterNR. For rat-Type set to eutra: the encoding of the capabilityRequestFilter is defined by the UECapabilityEnquiry message as defined in TS36.331, where the RAT-Type in UE-CapabilityRequest only includes 'eutra'. The rat-Type field describes the RAT type by which the network (NW) requests UE capabilities.

[0115] The UE-CapabilityRequestFilterNR IE can be used to request filtered UE capabilities. Based on some examples, the structure of the UE-CapabilityRequestFilterNR IE can be as follows:

[0116] It should be noted that in the example IE above, the underlined field FreqBandInformationNR-v18xy is designed to indicate the available frequency range for each supported frequency band included in the existing fields of FreqBandInformationNR in FreqBandList. In this example, if frequencyBandListFilter-v18xy exists, the size of the entries should be the same as that of frequencyBandListFilter. In other words, each entry in the new filter list (i.e., frequencyBandListFilter-v18xy) indicates the available frequency range corresponding to the frequency band at the same entry in the original filter list (i.e., frequencyBandListFilter). For example, the first entry for an available frequency range in the new filter list corresponds to the first entry for a frequency band in the original list, and so on.

[0117] The FreqBandList IE can be used by the network to request combinations of NR CA, NR non-CA, and / or MR-DC bands for a specific NR and / or E-UTRA band and / or up to a specific number of carriers and / or up to a specific aggregate bandwidth. It can also be used to request feature sets (for NR) and combinations of feature sets (for NR and MR-DC). For NR sidelink communication, this is used by the initiating UE to request sidelink UE radio access capabilities from a peer UE.

[0118] According to some examples, a FreqBandList IE can have the following structure, where the underlined field is used to provide information about the frequency range(s) used by the network operator for the frequency band:

[0119]

[0120] According to some examples, if the UE receives a carrierFrequencyRangeNR-List IE, for each frequency band combination, if the UE supports an MSD that is different from the MSD specified in 3GPP TS 38.101, the UE includes the supported MSD value for the corresponding frequency band in the frequency band combination.

[0121] Based on some examples, the UE can report the necessary MSD capability information to the network, and the network can obtain the MSD capability information only for the frequency range applicable to its network operation.

[0122] Figure 9 An example method flow is shown. This method can be executed, for example, by a UE as described herein.

[0123] In 900, the method includes receiving an indication from a network, the indication including multiple frequency bands of the network and at least one frequency range of at least one of the multiple frequency bands of the network. The indication can be received from a network node (such as a base station, gNB, etc.).

[0124] In 902, the method includes determining MSD information based on the indication. In 904, the method includes sending the MSD information to the network.

[0125] Figure 10 An example method flow is shown. This method can be executed, for example, by a network as described herein. This method can be executed by network nodes, gNBs, etc.

[0126] In 1000, the method includes sending an indication to a user equipment, the indication including a plurality of frequency bands of the network and at least one frequency range of at least one of the plurality of frequency bands of the network.

[0127] In 1002, the method includes receiving MSD information already determined by the user equipment based on an instruction.

The control device may include at least one random access memory (RAM) 1111a, at least one read-only memory (ROM) 1111b, at least one processor 1112, 1113, and an input / output interface 1114.
