Description
本发明涉及无线通信技术领域,更具体地,本发明涉及由用户设备执行IDC辅助信息配置和上报的方法以及相应的用户设备。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.
为了能够同时接入多种网络,很多UE中都同时装有不同技术的无线收发机,例如LTE、NR、WiFi、蓝牙等。同一个UE中这些收发机距离很近,当它们工作在相邻频点或者次谐波频点就会互相产生干扰,这就是IDC干扰(设备内共存干扰),也可以称为IDC问题。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.
为了解决UE内部的IDC问题,UE检测IDC干扰,当其无法自己解决IDC干扰时,UE上报辅助信息给网络,由网络通过调整对UE的调度以解决3GPP接入技术(如LTE、NR等)和非3GPP接入技术之间(如WiFi、蓝牙等)的IDC干扰。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.).
2021年12月,RAN#94次全会上,针对版本18的In-Device Co-existence(IDC)enhancements for NR and MR-DC in enhancements的工作项目被提出(参见非专利文献:RP-213589 New WI:In-Device Co-existence(IDC)enhancements for NR and MR-DC),并获批准。该工作项目的目标包括支持增强FDM方法和支持TDM方法用于解决3GPP和非3GPP接入技术(例如WiFi)之间的IDC干扰问题。所针对的场景包括NR独立组网、NR-DC和EN-DC。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.
所谓的FDM方法的基本概念,就是网络在收到UE上报的IDC辅助信息后,通过异频切换、删除/去激活SCell、调整上行物理资源等方式将3GPP接入技术和非3GPP接入技术在频域上错开从而避免IDC干扰。所谓的TDM方法的基本概念,就是保证3GPP接入技术和非3GPP接入技术在时域上错开,即一种技术的发送和另一种技术的接收不会同时进行,从而避
免IDC干扰。从UE侧来看,对于FDM方法和TDM方法需要提供对应的辅助信息给网络。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.
本发明讨论TDM方法中IDC辅助信息上报的上报内容和上报流程。This invention discusses the reporting content and reporting process of IDC auxiliary information reporting in the TDM method.

以下,对本发明的相关技术给出说明。Below, a description will be given of the technology related to the present invention.
对于NR独立组网:For NR independent networking:
网络通过RRC专有信令为UE配置IDC参数,其中包括NR候选服务频率列表(candidateServingFreqListNR)。UE根据这些NR候选频率检测是否存在IDC干扰问题。当UE在网络配置的candidateServingFreqListNR的频点上检测到IDC干扰问题,UE在上报给网络的IDC辅助信息中携带受到IDC问题影响的载波频点列表(affctedCarrierFreqList)。如果包含在candidateServingFreqListNR中的频点的上行CA组合正在经历IDC问题并且UE无法自己解决,则UE上报给网络的辅助信息中携带这些受IDC问题影响的载波频点组合(affectedCarrierFreqCombList)列表。在版本18中的增强FDM方法中,除了上,除了上报频点列表,还可以上报受IDC问题影响的BWP列表和/或PRB列表,提供更细粒度的IDC干扰辅助信息给网络。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.
对于EN-DC组网:For EN-DC networking:
gNB通过CG-Config消息将candidateServingFreqListNR发送给eNB。eNB通过RRC专有信令将candidateServingFreqListNR配置给UE。当UE检测到IDC问题,UE在上报给网络的IDC辅助信息中携带受到IDC问题影响的E-UTRAN的载波频点(carrier frequency)列表和受到IDC问题影响的NR载波频点列表。eNB收到UE上报的IDC辅助信息后将其中的受
到IDC问题影响的NR载波频点列表通过CG-ConfigInfo转发给gNB。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.
在LTE中,TDM方法是通过UE上报即上报期望的DRX参数信息和/或期望的HARQ调度参数信息。In LTE, the TDM method is to report the expected DRX parameter information and/or the expected HARQ scheduling parameter information through the UE.
连接态DRX:Connected DRX:
在RRC连接态,网络可以配置连接态DRX,让UE周期性的在某些时候进入睡眠状态,不去监听PDCCH,而需要监听PDCCH的时候,则从睡眠状态中唤醒,这样就可以使UE达到省电的目的。UE从睡眠状态醒来监听PDCCH的开始的一段时长由drx-onDurationTimer定时器控制,drx-onDurationTimer超时后UE可能会进入睡眠状态。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.
如果网络配置UE提供为了节能UE所期望的DRX参数信息,UE出于节能的目的,可以向网络上报所期望的DRX参数信息,所期望的DRX参数信息包含在UEAssistanceInformation(UE辅助信息)消息中,并在发送UEAssistanceInformation消息后启动一个禁止(prohibit)定时器T346a。当所期望的DRX参数信息发生改变,并且禁止定时器T346a没有在运行,可以再次发送带有期望的DRX参数信息的UEAssistanceInformation消息并启动T346a。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.
本发明讨论在TDM方法引入到NR IDC后,UE如何进行IDC辅助参数中的期望的DRX参数和期望的上行和/或下行传输参数上报。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.
通过本发明,UE能够正确地为解决IDC问题而上报期望的DRX参数,同时能够避免频繁的UE辅助信息上报,减少功耗。进而,UE还能够正确地为解决IDC问题而上报期望的上行和/或下行传输参数。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.
