Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more specifically, to a method for executing IDC auxiliary information reporting by a user equipment and a corresponding user equipment. Background Art

[0002] In order to access multiple networks at the same time, many UEs are equipped with wireless transceivers of different technologies, such as LTE, NR, WiFi, Bluetooth, etc. These transceivers in the same UE are very close to each other. When they work at adjacent frequencies or subharmonic frequencies, they will interfere with each other. This is IDC (Intra-Device Coexistence Interference) interference, which can also be called the IDC problem.

[0003] In order to solve the IDC problem inside the UE, the UE detects IDC interference. When it cannot solve the IDC interference by itself, the UE reports auxiliary information to the network, and the network adjusts the scheduling of the UE to solve the IDC interference between 3GPP access technologies (such as LTE, NR, etc.) and non-3GPP access technologies (such as WiFi, Bluetooth, etc.).

[0004] In December 2021, at the RAN#94 plenary meeting, a work item for In-Device Co-existence (IDC) enhancements for NR and MR-DC in enhancements for version 18 was proposed and approved (see non-patent literature: RP-213589 New WI: In-Device Co-existence (IDC) enhancements for NR and MR-DC). The goals of this work item include supporting enhanced FDM methods and supporting TDM methods for solving IDC interference problems between 3GPP and non-3GPP access technologies (such as WiFi). The scenarios targeted include NR independent networking, NR-DC and EN-DC.

[0005] The basic concept of the so-called FDM method is that after receiving the IDC auxiliary information reported by the UE, the network staggers the 3GPP access technology and the non-3GPP access technology in the frequency domain by means of frequency switching, deleting / deactivating SCell, adjusting uplink physical resources, etc., so as to avoid IDC interference. The basic concept of the so-called TDM method is to ensure that the 3GPP access technology and the non-3GPP access technology are staggered in the time domain, that is, the sending of one technology and the receiving of another technology will not be carried out at the same time, so as to avoid IDC interference. From the UE side, corresponding IDC auxiliary information needs to be provided to the network for the FDM method and the TDM method. The FDM method is enhanced in version 18, and the UE provides more fine-grained auxiliary information to the network, so that the network can more accurately avoid IDC interference.

[0006] Therefore, it is necessary to discuss the relevant processes of IDC auxiliary information reporting in the FDM method and the TDM method. Summary of the invention

[0081] Hereinafter, a description is given of related art of the present invention.

[0082] IDC FDM auxiliary information reporting

[0083] The network configures IDC FDM auxiliary configuration parameters for the UE through RRC dedicated signaling, which may include the NR candidate serving frequency list (candidateServingFreqListNR). When the UE detects an IDC interference problem on the frequency of the NR candidate serving frequency list configured by the network, the UE reports IDC auxiliary information to the network, which carries a list of carrier frequencies affected by the IDC problem (affectedCarrierFreqList). If the uplink CA combination (the CA combination is composed of the frequencies included in the candidateServingFreqListNR) is experiencing an IDC problem and the UE cannot solve it by itself, the IDC auxiliary information reported by the UE to the network carries a list of carrier frequency combinations affected by the IDC problem (affectedCarrierFreqCombList). If the DC combination (the DC combination is composed of the frequencies included in the candidateServingFreqListNR) is experiencing an IDC problem and the UE cannot solve it by itself, the IDC auxiliary information reported by the UE to the network carries a list of carrier frequency combinations affected by the IDC problem.

[0084] In the enhanced FDM method in Release 18, the network can configure IDC FDM auxiliary configuration parameters for the UE through RRC dedicated signaling, which may include a list of NR candidate serving frequency ranges (candidateServingFreqRangeListNR), each of which may include a center frequency and optionally a bandwidth. When the UE detects an IDC interference problem in the frequency range of the NR candidate serving frequency range list configured by the network, the UE reports IDC FDM auxiliary information to the network, that is, the IDC auxiliary information carries a list of frequency ranges affected by the IDC FDM problem (affectedCarrierFreqRangeList), where each frequency range affected by the IDC problem may include a center frequency and a bandwidth. If an IDC problem is being experienced in the uplink CA combination (the CA combination is composed of frequency ranges included in the NR candidate serving frequency range list) and the UE cannot resolve it by itself, the UE carries a list of frequency range combinations affected by the IDC problem (affectedCarrierFreqRangeCombList) in the IDC FDM auxiliary information reported to the network by the UE. If an IDC problem is being experienced in a DC (or MR-DC) combination (the DC combination consists of frequency ranges included in the NR candidate serving frequency range list) and the UE is unable to resolve it by itself, the IDC FDM assistance information reported by the UE to the network carries a list of frequency range combinations affected by the IDC problem.

[0085] The IDC FDM auxiliary information includes, but is not limited to: a list of carrier frequencies affected by the IDC problem, a list of carrier frequency combinations affected by the IDC problem, a list of frequency ranges affected by the IDC problem, and a list of frequency range combinations affected by the IDC problem.

[0086] IDC TDM auxiliary information reporting

[0087] The network configures IDC TDM auxiliary configuration parameters for the UE through RRC dedicated signaling, which may include an indication of whether the UE is required to report IDC TDM auxiliary information. If the network indicates that the UE needs to report IDC TDM auxiliary information, when the UE detects an IDC problem on one or some carrier frequencies or frequency ranges, the UE can initiate IDC TDM auxiliary information reporting.

[0088] IDC FDM auxiliary information and IDC TDM auxiliary information may be collectively referred to as IDC auxiliary information. IDC FDM auxiliary information may be reported by carrying IDC FDM auxiliary information in the IDC auxiliary information. IDC TDM auxiliary information may be reported by carrying IDC TDM auxiliary information in the IDC auxiliary information.

[0089] If the IDC auxiliary information reported by the UE to the network carries the IDC TDM auxiliary information, it must also carry the IDCFDM auxiliary information so that the network can make effective adjustments to the scheduling resources to avoid the IDC problem.

[0090] According to the prior art, the UE initiates IDC auxiliary information reporting according to the IDC TDM auxiliary configuration. If the IDC auxiliary information cannot carry the IDC FDM auxiliary information, it cannot carry the IDC TDM auxiliary information alone. Whether the IDC auxiliary information can carry the IDC FDM auxiliary information cannot be determined according to the IDC TDM auxiliary configuration parameters, which will result in invalid IDC auxiliary information (containing neither IDC FDM auxiliary information nor IDC TDM auxiliary information) or empty messages being reported to the network, resulting in waste of signaling and power consumption.

[0091] The present invention discusses how UE processes IDC auxiliary configuration to report IDC auxiliary information. Through the present invention, UE can correctly report IDC auxiliary information to the network, and at the same time can avoid invalid IDC auxiliary information reporting, reducing signaling and power consumption.

That is, when initiating IDC TDM auxiliary information reporting, not only the IDC TDM auxiliary configuration needs to be checked, but also the IDC FDM auxiliary configuration or the current IDC FDM auxiliary information needs to be checked.
