[0029] Figure 1 The present invention is a schematic flow chart illustrating a method for sending configuration information according to an embodiment of the present disclosure. The configuration information sending method illustrated in this embodiment can be executed by a base station, including but not limited to base stations in 4G, 5G, and 6G communication systems, which can communicate with terminals, including but not limited to mobile phones, tablets, wearable devices, sensors, IoT devices, and other communication devices.
[0030] like Figure 1 As shown, the configuration information sending method may include the following steps:
[0031] In step S101, a Radio Resource Control (RRC) release message is sent to a terminal, where the RRC release message carries configuration information applicable to the terminal performing small data transmission (SDT) in an inactive state.
[0032] In one embodiment, when determining that the terminal is about to leave the connected state, the base station may send an RRC release message to the terminal to instruct the terminal to leave the connected state, wherein the RRC release message may instruct the terminal to enter the idle state or the inactive state.
[0033] The RRC release message may carry configuration information applicable to the terminal performing SDT in the inactive state, which can be used by the terminal when performing SDT in the inactive state. In one embodiment, the configuration information includes at least one of the following: logical channel (LC) configuration information; buffer status report (BSR) configuration information; and power margin report (PHR) configuration information.
[0034] Among them, the way in which the terminal performs SDT in inactive can be performed during the random access process, for example, by carrying data through Msg3 to send to the base station in the 4-step random access process, for example, by carrying data through MsgA to send to the base station in the 2-step random access process; or the dedicated PUSCH (Physical Uplink Shared Channel) configured on the network side can be used to send data to the base station in the uplink, and the specific implementation methods include but are not limited to uplink grant exemption (Configure Grant, CG) and pre-allocated uplink resources (Preallocated Uplink Resource, PUR).
[0035] When the terminal is inactive and performing SDT, it not only needs to send data to the base station according to the time and frequency resources configured by the base station, but may also need to send other information, such as buffer status report (BSR), power headroom report (PHR), and needs to be constrained by the logical channel priority (LCP) mapping restrictions.
[0036] Although the terminal also needs to send BSR and PHR to the terminal in the connected state and is subject to the LCP mapping restrictions, the BSR configuration information, PHR configuration information, LCP mapping restrictions, etc. configured by the base station for the terminal for the connected state may not be applicable to the terminal performing SDT in the inactive state.
[0037] According to an embodiment of the present disclosure, the base station can carry configuration information applicable to the terminal performing SDT in the inactive state in the RRC release message, so that when the configuration information configured for the terminal for communication in the connected state is not applicable to the terminal performing SDT in the inactive state, the terminal can smoothly perform SDT in the inactive state according to the configuration information carried in the RRC release message.
[0038] How the terminal determines that the configuration information carried in the RRC release message is applicable to the terminal performing SDT in the inactive state is described below through several embodiments. Of course, the determination method is not limited to the following embodiments and can be specifically set as needed.
[0039] In one embodiment, the configuration information may be set at a predetermined position in the RRC release message. The configuration information at the predetermined position is predetermined to be used when the terminal performs SDT in the inactive state.
[0040] In one embodiment, the SDT configuration information can be carried through the RRC release message, and then the configuration information applicable to the terminal performing SDT in the inactive state is set in the SDT configuration information. Thus, when the terminal obtains the configuration information applicable to the terminal performing SDT in the inactive state in the SDT configuration information, it can be determined that the obtained configuration information is used when performing SDT in the inactive state.
[0041] In one embodiment, indication information may be carried in the RRC release message to indicate the role of the carried configuration information, so that the terminal may determine, based on the indication information, whether the configuration information is used when performing SDT in the inactive state.
[0042] In one embodiment, the LC configuration information includes logical channel priority (LCP) mapping restrictions.
[0043] When the terminal performs SDT in the inactive state, it is still subject to the LCP mapping restrictions. Therefore, the LCP mapping restrictions can be set in the LC configuration information to ensure that when the terminal performs SDT in the inactive state, the uplink resources used on each logical channel can still be reasonably restricted according to the LCP mapping restrictions.
[0044] In one embodiment, the LCP mapping restriction includes at least one of the following: an allowed uplink authorization exemption list allowedCG-List; an allowed uplink authorization exemption list for small data transmission allowedCG-List for SDT.
[0045] Among them, allowedCG-List can set the configuration authorization allowed for transmission; similarly, allowedCG-Listfor SDT can set the configuration authorization allowed for small data transmission.
[0046] Since the terminal can be implemented based on CG when it subsequently enters the inactive state to perform SDT, that is, SDT is performed on the uplink resources corresponding to the CG, at least one of the allowedCG-List and allowedCG-List for SDT is set in the LCP mapping restriction, so that the terminal can determine the resources corresponding to the CG for SDT according to the allowedCG-List and / or allowedCG-List for SDT, ensuring that the terminal can at least perform SDT in the inactive state.
[0047] It should be noted that when the LCP mapping restriction includes allowedCG-List and allowedCG-List forSDT, since allowedCG-List for SDT is specifically set for SDT, it is more adaptable to SDT, and the UE can perform SDT based on the resources corresponding to the CG in allowedCG-List for SDT.
[0048] In one embodiment, the LCP mapping restriction further includes at least one of the following:
[0049] The allowed subcarrier spacing list allowedSCS-List can set the subcarrier spacing allowed for transmission;
[0050] Maximum physical uplink shared channel duration maxPUSCH-Duration, which can set the maximum duration of PUSCH transmission allowed;
[0051] Uplink grant-free type 1 allowed configuredGrantType1Allowed, which can set whether type 1 CG can be used for transmission;
[0052] Allowed serving cells allowedServingCells, which can set the cells allowed for transmission;
[0053] The allowed physical layer priority index allowedPHY-PriorityIndex can be used to set the physical layer priority index of the dynamic grant allowed for transmission.
[0054] In one embodiment, on the basis of the LCP mapping restriction including allowedCG-List and / or allowedCG-List forSDT, other contents may also be included, so that the LCP mapping of the terminal when performing SDT in the inactive state can be appropriately restricted from other aspects, which is conducive to ensuring that the terminal performs SDT smoothly in the inactive state.
[0055] In one embodiment, the LC configuration information multiplexes the logical channel configuration information element LogicalChannelConfig IE or is a newly introduced IE.
[0056] In the RRC release message, a LogicalChannelConfig IE can be set to carry logical channel configuration information, and the LC configuration information in this embodiment can be sent using the LogicalChannelConfig IE. Accordingly, there is no need to introduce a new IE in the RRC release message, avoiding adjustment of the existing RRC release; of course, it is also possible to introduce a new IE in the RRC release message and carry the LC configuration information through the newly introduced IE.
[0057] In addition, the LC configuration information may also be carried in an upper-level IE of the LogicalChannelConfig IE, such as the RLC-BearerConfig IE, or carried in an upper-level IE of the RLC-BearerConfig IE, such as the CellGroupConfig IE.
[0058] In one embodiment, the BSR configuration information includes at least one of the following: a periodic buffer status report timer periodicBSR-Timer; and a retransmission buffer status report timer retxBSR-Timer.
[0059] In one embodiment, when it is determined that the SDT of the terminal supports scheduling request, the BSR configuration information further includes: a logical channel scheduling request delay timer logicalChannelSR-DelayTimer.
[0060] When a terminal performs SDT, the uplink transmission that it can perform is limited compared to that in the connected state. For example, some terminals support sending Scheduling Requests (SRs) during SDT, while some terminals do not. The logicalChannelSR-DelayTimer mainly applies to the process of the terminal sending SRs. If a terminal does not support sending SRs, even if the logicalChannelSR-DelayTimer is configured for the terminal, the terminal will not use the logicalChannelSR-DelayTimer, resulting in a waste of communication resources.
[0061] Therefore, the base station can determine whether the SDT of the terminal supports SR. If it supports SR, the logicalChannelSR-DelayTimer can be further carried in the configuration information. If it does not support SR, it is not necessary to carry the logicalChannelSR-DelayTimer in the configuration information to avoid wasting communication resources.
[0062] In one embodiment, the BSR configuration information reuses the buffer status report configuration information element bsr-ConfigIE or a newly introduced IE.
[0063] In the RRC release message, a bsr-Config IE may be provided to carry cache status configuration information. The BSR configuration information in this embodiment may be sent using the bsr-Config IE. Accordingly, it is not necessary to introduce a new IE in the RRC release message, thereby avoiding adjustment of the existing RRC release. Of course, a new IE may also be introduced in the RRC release message, and the BSR configuration information may be carried through the newly introduced IE.
[0064] In addition, the BSR configuration information may also be carried in an upper-level IE of the bsr-Config IE, such as the mac-CellGroupConfig IE.
[0065] In one embodiment, the PHR configuration information includes at least one of the following: power margin report periodic timer phr-PeriodicTimer; power margin report prohibition timer phr-ProhibitTimer; power margin report transmission power factor change phr-Tx-PowerFactorChange; multiple power margin report multiplePHR; power margin report type 2 other cell phr-Type2OtherCell; power margin report mode other uplink unauthorized phr-ModeOtherCG; FR2 frequency band maximum permissible exposure report mpe (maximum permissible exposure)-Reporting-FR2.
[0066] In one embodiment, the PHR configuration information reuses the buffer status report configuration information element phr-ConfigIE or is a newly introduced IE.
[0067] In the RRC release message, a phr-Config IE may be provided to carry power margin report configuration information, and the PHR configuration information in this embodiment may be sent using the phr-Config IE. Accordingly, it is not necessary to introduce a new IE in the RRC release message, thereby avoiding adjustment of the existing RRC release. Of course, a new IE may also be introduced in the RRC release message, and the PHR configuration information may be carried through the newly introduced IE.
[0068] In addition, the BSR configuration information may also be carried in an upper-level IE of the phr-Config IE, such as the mac-CellGroupConfig IE.
[0069] In one embodiment, when the RRC release message is used to instruct the terminal to enter an inactive state, the RRC release message carries the configuration information.
[0070] RRC release can be used to instruct the terminal to enter the idle state or the inactive state. Since the configuration information carried by the RRC release in the embodiment of the present disclosure is for use when the terminal performs SDT in the inactive state, the base station can first determine whether the RRC release message is used to instruct the terminal to enter the idle state or the inactive state.
[0071] If the RRC release message is used to instruct the terminal to enter the idle state, then the configuration information does not need to be carried in the RRC release message to avoid wasting communication resources; when the RRC release message is used to instruct the terminal to enter the inactive state, the configuration information is carried in the RRC release message for use by the terminal in the SDT process when it subsequently enters the inactive state.
[0072] Figure 2 The present invention is a schematic flow chart illustrating a method for obtaining configuration information according to an embodiment of the present disclosure. The configuration information obtaining method illustrated in this embodiment can be executed by a terminal, which can communicate with a base station as a user equipment (UE). The base station includes, but is not limited to, base stations in 4G, 5G, and 6G communication systems. The terminal includes, but is not limited to, mobile phones, tablet computers, wearable devices, sensors, IoT devices, and other communication devices.
[0073] like Figure 2 As shown, the configuration information acquisition method may include the following steps:
[0074] In step S201, an RRC release message sent by a base station is received;
[0075] In step S202, configuration information for performing small data transmission (SDT) in the inactive state is obtained from the RRC release message.
[0076] In one embodiment, when determining that the terminal is about to leave the connected state, the base station may send an RRC release message to the terminal to instruct the terminal to leave the connected state, wherein the RRC release message may instruct the terminal to enter the idle state or the inactive state.
[0077] The RRC release message may carry configuration information applicable to the terminal performing SDT in the inactive state, which can be used by the terminal when performing SDT in the inactive state. In one embodiment, the configuration information includes at least one of the following: logical channel (LC) configuration information; buffer status report (BSR) configuration information; and power margin report (PHR) configuration information.
[0078] Among them, the way in which the terminal performs SDT when inactive can be performed during the random access process, for example, by carrying data through Msg3 to send to the base station during the 4-step random access process, for example, by carrying data through MsgA to send to the base station during the 2-step random access process; or the dedicated PUSCH uplink configured on the network side can be used to send data to the base station. The specific implementation methods include but are not limited to uplink authorization exemption and pre-allocation of uplink resources.
[0079] When the terminal is inactive and performing SDT, it not only needs to send data to the base station according to the time-frequency resources configured by the base station, but may also need to send other information, such as buffer status report and power margin report, and needs to be constrained by the logical channel priority mapping restrictions.
[0080] Although the terminal also needs to send BSR and PHR to the terminal in the connected state and is subject to the LCP mapping restrictions, the BSR configuration information, PHR configuration information, LCP mapping restrictions, etc. configured by the base station for the terminal for the connected state may not be applicable to the terminal performing SDT in the inactive state.
[0081] According to an embodiment of the present disclosure, the base station may carry configuration information applicable to the terminal performing SDT in the inactive state in the RRC release message. After receiving the RRC release message, the terminal may obtain the configuration information for performing small data transmission SDT in the inactive state from the RRC release message for use when performing SDT in the inactive state. Accordingly, even if the configuration information applicable to communication in the connected state configured for the terminal by the terminal is not applicable to the terminal performing SDT in the inactive state, the terminal can also smoothly perform SDT in the inactive state according to the configuration information carried in the RRC release message.
[0082] How the terminal determines that the configuration information carried in the RRC release message is applicable to the terminal performing SDT in the inactive state is described below through several embodiments. Of course, the determination method is not limited to the following embodiments and can be specifically set as needed.
[0083] In one embodiment, the configuration information may be set at a predetermined position in the RRC release message. The configuration information at the predetermined position is predetermined to be used when the terminal performs SDT in the inactive state.
[0084] In one embodiment, the SDT configuration information can be carried through the RRC release message, and then the configuration information applicable to the terminal performing SDT in the inactive state is set in the SDT configuration information. Thus, when the terminal obtains the configuration information applicable to the terminal performing SDT in the inactive state in the SDT configuration information, it can be determined that the obtained configuration information is used when performing SDT in the inactive state.
[0085] In one embodiment, indication information may be carried in the RRC release message to indicate the role of the carried configuration information, so that the terminal may determine, based on the indication information, whether the configuration information is used when performing SDT in the inactive state.
[0086] In one embodiment, the configuration information includes at least one of the following: logical channel LC configuration information; buffer status report BSR configuration information; power headroom report PHR configuration information.
[0087] In one embodiment, the LC configuration information includes logical channel priority (LCP) mapping restrictions.
[0088] When the terminal performs SDT in the inactive state, it is still subject to the LCP mapping restrictions. Therefore, the LCP mapping restrictions can be set in the LC configuration information to ensure that when the terminal performs SDT in the inactive state, the uplink resources used on each logical channel can still be reasonably restricted according to the LCP mapping restrictions.
[0089] In one embodiment, the LCP mapping restriction includes at least one of the following: an allowed uplink grant exemption list allowedCG-List; an allowed uplink grant exemption list for small data transmission allowedCG-List for SDT.
[0090] Since the terminal can be implemented based on CG when it subsequently enters the inactive state to perform SDT, that is, SDT is performed on the uplink resources corresponding to the CG, at least one of the allowedCG-List and allowedCG-List for SDT is set in the LCP mapping restriction, so that the terminal can determine the resources corresponding to the CG for SDT according to the allowedCG-List and / or allowedCG-List for SDT, ensuring that the terminal can at least perform SDT in the inactive state.
[0091] It should be noted that when the LCP mapping restriction includes allowedCG-List and allowedCG-List forSDT, since allowedCG-List for SDT is specifically set for SDT, it is more adaptable to SDT, and the UE can perform SDT based on the resources corresponding to the CG in allowedCG-List for SDT.
[0092] In one embodiment, the LCP mapping restriction also includes at least one of the following: an allowed subcarrier spacing list allowedSCS-List; a maximum physical uplink shared channel duration maxPUSCH-Duration; uplink grant-free type 1 allowed configuredGrantType1Allowed; allowed serving cells allowedServingCells; and an allowed physical layer priority index allowedPHY-PriorityIndex.
[0093] In one embodiment, on the basis of the LCP mapping restriction including allowedCG-List and / or allowedCG-List forSDT, other contents may also be included, so that the LCP mapping of the terminal when performing SDT in the inactive state can be appropriately restricted from other aspects, which is conducive to ensuring that the terminal performs SDT smoothly in the inactive state.
[0094] In one embodiment, the BSR configuration information includes at least one of the following: a periodic buffer status report timer periodicBSR-Timer; and a retransmission buffer status report timer retxBSR-Timer.
[0095] In one embodiment, when the SDT of the terminal supports scheduling request, the BSR configuration information further includes: a logical channel scheduling request delay timer logicalChannelSR-DelayTimer.
[0096] In one embodiment, the PHR configuration information includes at least one of the following: power margin report periodic timer phr-PeriodicTimer; power margin report prohibition timer phr-ProhibitTimer; power margin report transmission power factor change phr-Tx-PowerFactorChange; multiple power margin report multiplePHR; power margin report type 2 other cell phr-Type2OtherCell; power margin report mode other uplink unauthorized phr-ModeOtherCG; FR2 frequency band maximum permissible radiation exposure report mpe-Reporting-FR2.
[0097] Figure 3 FIG. 1 is a schematic flow chart of another configuration information acquisition method according to an embodiment of the present disclosure. Figure 3 As shown, the method further includes:
[0098] In step S301, when performing SDT in the inactive state, the configuration information is used.
[0099] In one embodiment, since the configuration information carried in the RRC release message is for use when the terminal performs SDT in the inactive state, the terminal may not use the configuration information in other states, such as the idle state and the connected state, and only use the configuration when performing SDT in the inactive state.
[0100] Accordingly, when the base station configures configuration information applicable to other states for the terminal, and the configuration information applicable to other states is different from the configuration information carried in the RRC release message, it can avoid the terminal using the configuration information carried in the RRC release message to communicate in other states and causing communication problems.
[0101] Figure 4 FIG is a schematic flow chart of another configuration information acquisition method according to an embodiment of the present disclosure. Figure 4 As shown, the method further includes:
[0102] In step S401, when entering the connected state or the idle state, the configuration information is released.
[0103] In one embodiment, since the configuration information carried in the RRC release message is for use when the terminal performs SDT in the inactive state, when the terminal enters the connected state or the idle state, the configuration information obtained from the RRC release message can be released, which is beneficial to reducing the occupancy of the terminal storage space.
[0104] In addition, the base station may also configure the terminal with configuration information for use by the terminal in the connected state or the idle state. For example, if the terminal is configured with LC configuration information, BSR configuration information, and PHR configuration information applicable to the connected state, then after entering the connected state, the terminal may use the LC configuration information, BSR configuration information, and PHR configuration information applicable to the connected state for communication; for example, if the terminal is configured with LC configuration information, BSR configuration information, and PHR configuration information applicable to SDT in the idle state, then after entering the air-conditioning state, the terminal may use the LC configuration information, BSR configuration information, and PHR configuration information applicable to SDT in the idle state for communication when performing SDT.
[0105] In one embodiment, the configuration information includes LC configuration information, and the terminal further stores the LC configuration information received in the connected state.
[0106] The LC configuration information received in the connected state may be applicable to the communication of the terminal in the connected state, for example, to reasonably limit the uplink resources used by each logical channel of the terminal during communication in the connected state.
[0107] In this case, the LC configuration information received in the connected state may be applicable to the use of the terminal when performing SDT in the inactive state, or may not be applicable to the use of the terminal when performing SDT in the inactive state. It may be indicated by the base station or determined by the terminal itself. The following uses several embodiments to illustrate the processing method of the LC configuration information received in the connected state.
[0108] Figure 5 FIG is a schematic flow chart of another configuration information acquisition method according to an embodiment of the present disclosure. Figure 5 As shown, the LC configuration information received in the connected state includes LCP mapping restrictions, and the method further includes:
[0109] In step S501, when the configuration information for performing small data transmission (SDT) in the inactive state is not obtained from the RRC release message, the LCP mapping restriction received in the connected state is disabled.
[0110] In one embodiment, when the RRC release message does not carry configuration information for performing SDT in the inactive state, the terminal may disable the LCP mapping restriction received in the connected state.
[0111] Since the LCP mapping restriction received in the connected state is applicable to terminal communication in the connected state, but may not be applicable to the terminal when performing SDT in the inactive state, even if the configuration information for SDT in the inactive state is not obtained in the RRC release message, the LCP mapping restriction received in the connected state can be disabled to avoid unnecessary restrictions on the terminal in the inactive state.
[0112] Figure 6 FIG is a schematic flow chart of another configuration information acquisition method according to an embodiment of the present disclosure. Figure 6 As shown, the LC configuration information received in the connected state includes an LCP mapping restriction, the LCP mapping restriction includes an allowedCG-List, and the method further includes:
[0113] In step S601, when the configuration information for small data transmission SDT in the inactive state is not obtained from the RRC release message, the LCP mapping restrictions other than allowedCG-List and / or allowedCG-List for SDT in the LCP mapping restrictions received in the connected state are disabled.
