Description

Method executed by user equipment and user equipment

Technical field

The present invention relates to the field of wireless communication technology. More specifically, the present invention relates to a method for configuring and reporting IDC auxiliary information by user equipment and the corresponding user equipment.

Background technique

In order to be able 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. When they work at adjacent frequencies or sub-harmonic frequencies, they will interfere with each other. This is IDC interference (in-device coexistence interference), which can also be called the IDC problem.

In order to solve the IDC problem within 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 problem of 3GPP access technologies (such as LTE, NR, etc.) and IDC interference between non-3GPP access technologies (such as WiFi, Bluetooth, etc.).

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

The basic concept of the so-called FDM method is that after receiving the IDC auxiliary information reported by the UE, the network combines 3GPP access technology and non-3GPP access technology through inter-frequency switching, deletion/deactivation of SCell, and adjustment of uplink physical resources. Staggered in the frequency domain to avoid IDC interference. The basic concept of the so-called TDM method is to ensure that 3GPP access technology and non-3GPP access technology are staggered in the time domain, that is, the transmission of one technology and the reception of another technology will not occur at the same time, thereby avoiding Free from IDC interference. From the UE side, corresponding auxiliary information needs to be provided to the network for the FDM method and the TDM method.

This invention discusses the reporting content and reporting process of IDC auxiliary information reporting in the TDM method.

Below, a description will be given of the technology related to the present invention.

For NR independent networking:

The network configures IDC parameters for the UE through RRC proprietary signaling, including the NR candidate serving frequency list (candidateServingFreqListNR). The UE detects whether there is an IDC interference problem based on these NR candidate frequencies. When the UE detects an IDC interference problem at the frequency of candidateServingFreqListNR configured by the network, the UE carries the list of carrier frequencies affected by the IDC problem (affctedCarrierFreqList) in the IDC auxiliary information reported to the network. If the uplink CA combination of frequencies included in candidateServingFreqListNR is experiencing an IDC problem and the UE cannot solve it by itself, the auxiliary information reported by the UE to the network carries a list of these carrier frequency combinations (affectedCarrierFreqCombList) affected by the IDC problem. In the enhanced FDM method in version 18, in addition to reporting the frequency point list, the BWP list and/or PRB list affected by IDC issues can also be reported to provide more fine-grained IDC interference auxiliary information to the network.

For EN-DC networking:

gNB sends candidateServingFreqListNR to eNB through CG-Config message. The eNB configures candidateServingFreqListNR to the UE through RRC proprietary signaling. When the UE detects an IDC problem, the UE carries the E-UTRAN carrier frequency list affected by the IDC problem and the NR carrier frequency list affected by the IDC problem in the IDC auxiliary information reported to the network. After receiving the IDC auxiliary information reported by the UE, the eNB will The list of NR carrier frequencies affected by the IDC problem is forwarded to gNB through CG-ConfigInfo.

In LTE, the TDM method is to report the expected DRX parameter information and/or the expected HARQ scheduling parameter information through the UE.

Connected DRX:

In the RRC connected state, the network can configure connected state DRX so that the UE periodically enters the sleep state at certain times without monitoring the PDCCH. When it needs to monitor the PDCCH, it wakes up from the sleep state, so that the UE can achieve For the purpose of power saving. The initial period of time when the UE wakes up from the sleep state to listen to the PDCCH is controlled by the drx-onDurationTimer timer. The UE may enter the sleep state after the drx-onDurationTimer times out.

If the network configures the UE to provide the DRX parameter information expected by the UE in order to save energy, the UE can report the expected DRX parameter information to the network for the purpose of energy saving. The expected DRX parameter information is included in the UEAssistanceInformation (UE assistance information) message. And after sending the UAssistanceInformation message, a prohibition timer T346a is started. When the expected DRX parameter information changes and the prohibition timer T346a is not running, the UEAssistanceInformation message with the expected DRX parameter information can be sent again and T346a can be started.

This invention discusses how the UE reports the expected DRX parameters and expected uplink and/or downlink transmission parameters in the IDC auxiliary parameters after the TDM method is introduced into the NR IDC.

Through the present invention, the UE can correctly report the expected DRX parameters to solve the IDC problem, and at the same time, it can avoid frequent reporting of UE auxiliary information and reduce power consumption. Furthermore, the UE can also correctly report expected uplink and/or downlink transmission parameters to solve the IDC problem.

Below, several embodiments of the present invention addressing the above problems are described in detail.

Example 1

If the network configures the UE to provide the DRX parameter information expected by the UE for power saving, the UE can report the DRX parameter information expected by the UE to the network for the purpose of power saving. If the network configures the UE to provide the IDC parameter information expected by the UE in order to solve the IDC problem, the UE can also report the DRX parameter information expected by the UE to the network in order to solve the IDC problem.

Optionally, the DRX expected parameters for solving the IDC problem and the DRX expected parameters for energy saving are respectively carried in two different cells, that is, two sets of parameters are used, and some of the two sets of parameters are Parameters may need to be provided to the network for both IDC and energy saving (which may be called public DRX expected parameters), while other parameters may be used only for IDC or only for energy saving.

Or, optionally, the DRX expected parameters reported for IDC and the DRX expected parameters reported for energy saving can be the same set of parameters, that is, reported using the same cell (for example, drx-Preference), which includes both public DRX expected parameters and Contains DRX expected parameters specifically for IDC and/or energy saving. To differentiate, the first DRX desired parameter may be present only for solving the IDC problem, and the second DRX desired parameter may be present only for energy saving.

Optionally, in step S101, the UE receives RRC proprietary signaling sent by the network, which includes IDC assistance information parameter configuration (idc-AssistanceConfig).

The UE determines whether it is configured to provide DRX expected parameters according to the IDC assistance information parameter configuration and/or the DRX expected parameter indication. Optionally, after the UE receives the IDC assistance information parameter configuration, if idc-AssistanceConfig is configured (for example, set to TRUE or setup), and/or if the DRX expected parameter indication is configured (for example, set to TRUE or setup), the UE It considers itself to be configured to provide DRX expected parameters (or the DRX expected parameters of the cell group, or the DRX expected parameters of MCG and/or SCG), otherwise it considers itself not to be configured to provide DRX expected parameters (or the cell DRX expected parameters for the group, or DRX expected parameters for the MCG and/or SCG).

Optionally, the expected DRX offset can be reported separately for the long DRX cycle and the short DRX cycle, for example, the expected long DRX offset drx-Offset (or drx-OffsetLongDRX) indicates the expected short DRX offset drx-OffsetShortDRX .

- Desired DRX slot offset (e.g. drx-SlotOffset): identified in A time slot-level delay before the start of drx-onDurationTimer. This time slot offset can be used to determine which time slot (in the subframe determined by drx-offset) the UE will start monitoring the PDCCH.

Optionally, the expected DRX slot offset can be reported for the long DRX cycle and the short DRX cycle respectively, for example, the expected long DRX slot offset drx-SlotOffset (or drx-SlotOffsetLongDRX) indicates the expected short DRX time slot. Slot offset drx-SlotOffsetShortDRX.

- Desired short DRX cycle (e.g. preferredDRX-ShortCycle).

- Desired short DRX cycle timer (e.g. preferredDRX-ShortCycleTime): switch to long DRX cycle after this timer expires.

Optionally, if the expected long DRX cycle (such as preferredDRX-LongCycle) is included or set in the DRX expectation parameter, the UE sets the drx-Offset (or drx-OffsetLongDRX) value should be less than the preferredDRX-LongCycle, starting radio frame The relationship between (SFN) and wireless subframe (subframe) should satisfy: [(SFN*10)+subframe number]modulo(preferredDRX-LongCycle)=drx-Offset.

Optionally, if the desired short DRX cycle (such as preferredDRX-ShortCycle) is included or set, the relationship between the UE-initiated radio frame (SFN) and the radio subframe (subframe) should satisfy: [(UE×10)+ subframe subframe number modulo(preferredDRX-ShortCycle)=(drx-Offset)modulo(preferredDRX-ShortCycle).

Optionally, in step S103, the UE starts a prohibition timer T1. The prohibition timer T1 can be T346a, or a new prohibition timer different from T346a. During the operation of the prohibition timer T1, the prohibition timer T1 is prohibited. Send a UE assistance information message containing DRX expected parameters.
