Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for performing IDC auxiliary information configuration and reporting by a user equipment and a corresponding user equipment.
Background
In order to be able to access multiple networks simultaneously, 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 together and interfere with each other when they operate at adjacent or subharmonic frequencies, which is IDC interference (in-device coexistence interference), also known as IDC problem.
In order to solve the IDC problem inside the UE, the UE detects IDC interference, and when it cannot solve IDC interference by itself, the UE reports auxiliary information to the network, and the network adjusts the scheduling of the UE to solve IDC interference between the 3GPP access technology (e.g., LTE, NR, etc.) and the non-3 GPP access technology (e.g., wiFi, bluetooth, etc.).
Work items for In-Device Co-existence (IDC) enhancements for NR and MR-DC In enhancements, version 18, were proposed and approved on the RAN #94 meeting, 12 months 2021 (see non-patent literature: RP-213589New 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-3 GPP access technologies (e.g., wiFi). The scenarios aimed at include NR independent networking, NR-DC and EN-DC.
The basic concept of the FDM method is that after the network receives IDC auxiliary information reported by the UE, the network staggers the 3GPP access technology and the non-3 GPP access technology in the frequency domain by means of inter-frequency switching, deleting/deactivating SCell, adjusting uplink physical resources, and the like, 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-3 GPP access technology are staggered in time domain, i.e. the transmission of one technology and the reception of the other technology are not performed simultaneously, so as to avoid IDC interference. From the UE side, corresponding auxiliary information needs to be provided to the network for the FDM method and the TDM method.
The invention discusses the reporting content and the reporting flow of the IDC auxiliary information reporting in the TDM method.

Hereinafter, a description is given of the related art of the present invention.
Independent networking for NR:
the network configures IDC parameters for the UE through RRC-specific signaling, including NR candidate service frequency list (candidatesendfreqlistnr). The UE detects whether IDC interference problems exist based on these NR candidate frequencies. When the UE detects an IDC interference problem on a frequency point of candidateeservingfreqlistnr configured by the network, the UE carries a carrier frequency point list (affectedcarrier freqlist) affected by the IDC problem in IDC auxiliary information reported to the network. If the upstream CA combinations of frequency points contained in candidateServingFreqListNR are experiencing IDC problems and the UE cannot resolve itself, the auxiliary information reported to the network by the UE carries a list of these carrier frequency point combinations (affectedcarrier freqcomblist) affected by IDC problems. In the enhanced FDM method of release 18, besides reporting the frequency point list, a BWP list and/or a PRB list affected by the IDC problem may be reported, and IDC interference auxiliary information with a finer granularity is provided to the network.
For EN-DC networking:
the gNB sends Candida paraeServer FreqListNR to the eNB via CG-Config message. The eNB configures candidatesendesvingfreqlistnr to the UE through RRC-specific signaling. When the UE detects the IDC problem, the UE carries a carrier frequency point (carrier frequency) list of the E-UTRAN affected by the IDC problem and an NR carrier frequency point list affected by the IDC problem in IDC auxiliary information reported to the network by the UE. After receiving the IDC auxiliary information reported by the UE, the eNB forwards an NR carrier frequency point list affected by the IDC problem to the gNB through CG-ConfigInfo.
In LTE, the TDM method is to report, i.e., report, the expected DRX parameter information and/or the expected HARQ scheduling parameter information by the UE.
Connection state DRX:
in the RRC connected state, the network may configure the connected DRX to enable the UE to periodically enter a sleep state at some time, without monitoring the PDCCH, and wake up from the sleep state when the PDCCH needs to be monitored, so that the UE may achieve the purpose of saving power. The duration of the start of the UE waking up from the sleep state to monitor the PDCCH is controlled by a drx-onduration timer, and the UE may enter the sleep state after the drx-onduration timer times out.
If the network configures the UE to provide the DRX parameter information desired by the UE for power saving purposes, the UE may report the desired DRX parameter information to the network, which is included in a UE assistance information message, and start a inhibit timer T346a after transmitting the UE assistance information message. When the desired DRX parameter information changes and the prohibit timer T346a is not running, the ueassanceinformation message with the desired DRX parameter information may be sent again and T346a may be started.
The present invention discusses how the UE may report the desired DRX parameters and the desired uplink and/or downlink transmission parameters among the IDC auxiliary parameters after the TDM approach is introduced into the NR IDC.
According to the invention, the UE can correctly report the expected DRX parameter for solving the IDC problem, and meanwhile, frequent UE auxiliary information reporting can be avoided, and the power consumption is reduced. Furthermore, the UE can also correctly report the desired uplink and/or downlink transmission parameters for addressing IDC issues.
Several embodiments of the present invention for the above-described problems are described in detail below.
Example 1
If the network configures the UE to provide DRX parameter information that is desired for power saving (power saving), the UE may report the DRX parameter information desired by the UE to the network for power saving purposes. If the network configures the UE to provide the desired IDC parameter information for the solution of the IDC problem, the UE may also report the DRX parameter information desired by the UE to the network for the solution of the IDC problem.
Alternatively, the DRX desired parameters for solving the IDC problem and the DRX desired parameters for power saving are carried in two different cells, respectively, i.e. two sets of parameters are used, some of which may be provided to the network for both IDC and for power saving (which may be referred to as common DRX desired parameters), while others may be used for IDC only or for power saving only.
Alternatively, the DRX expected parameters for IDC reporting and the DRX expected parameters for power saving reporting may be the same set of parameters, i.e. reporting with the same cell (e.g. DRX-reference), including both common DRX expected parameters and DRX expected parameters specific for IDC and/or power saving. To distinguish, the first DRX expected parameter may be present only when it is to solve IDC problem, and the second DRX expected parameter may be present only when it is to save power.
Fig. 1 is a flow chart of a method in a user equipment, UE, according to an embodiment of the invention.
Optionally, in step S101, the UE receives RRC-specific signaling sent by the network, including IDC auxiliary information parameter configuration (IDC-assureconfig).
The UE judges whether to be configured to provide the DRX expected parameter according to the IDC auxiliary information parameter configuration and/or the DRX expected parameter indication. Optionally, after the UE receives the IDC assistance information parameter configuration, if IDC-assureconfiguration (e.g. set to TRUE or setup) and/or if DRX desired parameter indication is configured (e.g. set to TRUE or setup), the UE considers itself to be configured to provide DRX desired parameters (or DRX desired parameters of the cell group, or DRX desired parameters of MCG and/or SCG), otherwise considers itself not to be configured to provide DRX desired parameters (or DRX desired parameters of the cell group, or DRX desired parameters of MCG and/or SCG).
Optionally, after the UE detects the IDC problem (and the UE cannot solve it by itself), the UE sends a UE assurelnfo message to the network, which contains the DRX expected parameters, or the DRX expected parameters of the cell group, or the DRX expected parameters of the MCG and/or SCG in step S102.
Optionally, the first DRX expected parameter may be included in the DRX expected parameter.
Wherein, optionally, the first DRX expected parameter comprises at least one of:
-a desired DRX offset (DRX-offset): from this offset value, it can be determined which subframe (subframe) of which radio frame (SFN) the UE starts listening to the PDCCH. Alternatively, the desired DRX Offset may be reported for the long DRX cycle and the short DRX cycle, respectively, e.g., an Offset DRX-Offset (or DRX-OffsetLongDRX) for the desired long DRX, indicating an Offset DRX-OffsetShortDRX for the desired short DRX.
-a desired DRX slot offset (e.g. DRX-SlotOffset): the delay at the slot level before the start of the drx-onduration timer is identified, from which slot offset it can be determined from which slot (of the subframe determined by drx-offset) the UE starts listening to the PDCCH.
Alternatively, the desired DRX slot offset may be reported for the long DRX cycle and the short DRX cycle, respectively, e.g., the slot offset DRX-SlotOffset (or DRX-SlotOffsetLongDRX) for the desired long DRX, indicating the slot offset DRX-SlotOffsetShortDRX for the desired short DRX.
A desired short DRX cycle (e.g., preferredDRX-ShortCycle).
A desired short DRX cycle timer (e.g. preferredDRX-ShortCycleTime): the long DRX cycle is used after the timer expires.
Alternatively, if a desired long DRX cycle (e.g., preferredDRX-LongCycle) is included in or set in the DRX desired parameter, the UE should set a value of DRX-Offset (or DRX-offsetlongcycle) smaller than the preferredDRX-LongCycle, and the relation of the starting radio frame (SFN) and the radio subframe (subframe) should satisfy: [ (SFN x 10) +subframe number ] module (preferredDRX-LongCycle) =drx-Offset.
Alternatively, if the desired short DRX cycle (e.g., preferredDRX-ShortCycle) is included or set, the relation of the UE-initiated radio frame (SFN) and the radio subframe (subframe) should satisfy: [ (sfn×10) +subframe number ] module (preferredDRX-ShortCycle) = (drx-Offset) module.
Optionally, in step S103, the UE starts a prohibit timer T1, where the prohibit timer T1 may be T346a or may be a new prohibit timer different from T346a, and during the operation of the prohibit timer T1, the UE assistance information message including the DRX desired parameter is prohibited from being sent.
Example 2
Based on the first embodiment, optionally, if the UE is configured to provide desired DRX parameter information for power saving, the UE performs at least one of:
if the desired DRX parameter information for the cell group is different from the desired DRX parameter information indicated in the last ue assurelnformation message for power saving transmitted for the cell group (unless the common desired DRX parameter is the only difference and the value of the common desired DRX parameter in the last ue assurelnformation message transmitted to solve IDC problem is the same), and the prohibit timer T346a is not running, the transmission of the ue assurelnformation message is initiated. The ue assistance information message includes DRX parameter information desired for power saving.
-initiating transmission of a ue assurelnformation message if the desired DRX parameter information for the cell group and the desired DRX parameter information indicated in the ue assurelnformation message for power saving last transmitted for the cell group are different and the common desired DRX parameter value of this time is the same as the value of the common desired DRX parameter in the ue assurelnformation message last transmitted for solving IDC problem and the prohibit timer T346a is not running. The message in ueassistance information contains a second DRX expected parameter (e.g., DRX inactivity timer) that is expected specifically for power saving.
-initiating transmission of a ue assurelnformation message if the desired DRX parameter information for the cell group and the desired DRX parameter information indicated in the ue assurelnformation message for power saving last transmitted for the cell group are different and the value of the common desired DRX parameter in the ue assurelnformation message last transmitted for solving IDC problems is different and the prohibit timer T346a is not running. The DRX expected parameters expected for power saving are included in the ueassistance information message.
Optionally, if the UE is configured to provide IDC assistance information for solving IDC problems, (optionally, if the UE is configured to need to provide desired DRX parameter information for solving IDC problems), the UE performs at least one of:
if the desired DRX parameter information for the cell group is different from the desired DRX parameter information indicated in the ueassuredly information message last transmitted for the cell group to solve IDC problem (unless the common desired DRX parameter is the only difference and the value of the common desired DRX parameter in the ueassuredly information message last transmitted for power saving is the same), the transmission of the ueassuredly information message is initiated, in which the desired DRX parameter information to solve IDC problem is contained.
-initiating transmission of a ue assuredly information message containing a first DRX desired parameter specific for IDC if the desired DRX parameter information for the cell group and the desired DRX parameter information indicated in the ue assuredly information message last transmitted for the cell group for solving IDC problems are different and the common desired DRX parameter value of this time is the same as the value of the common desired DRX parameter in the ue assuredly information message last transmitted for power saving.
-initiating transmission of a ue assayinformation message containing desired DRX parameter information for solving IDC problems if the desired DRX parameter information for the cell group is different from the desired DRX parameter information indicated in the ue assayinformation message last transmitted for the cell group for solving IDC problems and the common desired DRX parameter value in the ue assayinformation message last transmitted for saving power is different.
Optionally, before initiating the transmission of the ue assurelnformation message, it may also be determined whether the prohibit timer T1 is running, and if the prohibit timer T1 is not running, the transmission of the ue assurelnformation message is initiated.
Wherein, optionally, the common desired DRX parameter may be a subset of desired DRX parameters, including but not limited to at least one of: a long DRX cycle, a short DRX cycle, and a short DRX cycle timer.
Example 3
Optionally, in step S101, the UE receives RRC-specific signaling sent by the network, including IDC auxiliary information parameter configuration (IDC-assureconfig).
The UE judges whether the UE is configured to provide the expected uplink and/or downlink transmission parameters according to the IDC auxiliary information parameter configuration and/or the uplink and/or downlink transmission expected parameter indication. Optionally, after receiving the IDC assistance information parameter configuration, the UE considers itself to be configured to provide the desired uplink and/or downlink transmission parameters (or the desired uplink and/or downlink transmission parameters of the cell group, or the desired uplink and/or downlink transmission parameters of the MCG and/or SCG) if IDC-assanceconfig is configured (e.g. set to TRUE or setup), and/or if the uplink and/or downlink transmission desired parameter indication is configured (e.g. set to TRUE or setup), otherwise considers itself not to be configured to provide the desired uplink and/or downlink transmission parameters (or the desired uplink and/or downlink transmission parameters of the cell group, or the desired uplink and/or downlink transmission parameters of the MCG and/or SCG).
Optionally, in step S102, after the UE detects the IDC problem, a UE assistance information (UE assistance information) message is sent to the network, where the UE assistance information includes desired uplink and/or downlink transmission parameters, or desired uplink and/or downlink transmission parameters of the cell group, or desired uplink and/or downlink transmission parameters of the MCG and/or SCG.
Wherein optionally, the desired uplink and/or downlink transmission parameters may comprise desired TDD uplink and/or downlink transmission patterns (patterns).
