Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for transmitting configuration information. Background Technology

[0002] In Release 18 (R18) of the 3rd Generation Partnership Project (3GPP), cell on-off can be dynamically managed to conserve network equipment power. When a cell has little or no service, it can be shut down to save power, and then reactivated upon receiving a wake-up instruction from a user equipment (UE) or other network node. While the cell is off, it may be in a shallow sleep state, allowing for rapid transitions between sleep and wake-up states.

[0003] Before a community is dynamically shut down for energy conservation, connected user equipment within that community needs to switch to a new community through a handover process. The issue of excessive overhead on user equipment caused by this handover process needs to be addressed. Summary of the Invention

[0004] This disclosure provides a method, apparatus, and readable storage medium for transmitting configuration information.

[0005] In a first aspect, this disclosure provides a method for receiving configuration information, executed by a user equipment, the method comprising:

The configuration information is used to indicate that the first secondary cell among at least one secondary cell is configured as the second primary cell. The serving cell of the user equipment includes the first primary cell and the at least one secondary cell.

[0007] In the method disclosed herein, the user equipment can obtain the first secondary cell configured as the second primary cell in the serving cell based on the configuration information sent by the first network device. Therefore, when the first primary cell is shut down, the first secondary cell that has established a connection with the user equipment can be configured as the new primary cell, reducing unnecessary handover procedures for the user equipment and effectively lowering its overhead.

[0008] In some possible implementations, the method further includes:

[0024] In some possible implementations, the method further includes:

[0036] Thirdly, this disclosure provides a method for sending configuration information, executed by a second network device, the method comprising:

[0037] Send third auxiliary information to the first network device, the third auxiliary information being used to indicate whether the secondary cell corresponding to the second network device meets the set conditions for being the primary cell.

[0038] In the method disclosed herein, the second network device sends third auxiliary information to the first network device to inform whether the corresponding auxiliary cell can be used as the primary cell, thereby enabling the first network device to reasonably determine a more suitable second primary cell, so as to reduce the overhead of the user equipment handover process.

[0039] In some possible implementations, the method further includes:

[0081] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0082] like Figure 1 As shown, the method for transmitting configuration information provided in this embodiment can be applied to a wireless communication system 100, which may include a user equipment 101, a first network device 102, and a second network device 103. The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the first network device 102 or the second network device 103, including a primary carrier unit and one or more secondary carrier units.

[0083] User equipment 101 can be configured with multiple cells as serving cells, including one primary cell (Pcell) and one or more secondary cells (Scell). The first network device 102 corresponds to the primary cell of user equipment 101, and the second network device 103 corresponds to the secondary cell of user equipment 101.

[0084] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0085] The user equipment 101 shown above can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent, or terminal equipment, etc. This user equipment 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems and receive network services provided by the network devices. These network devices include, but are not limited to, the first network device 102 or the second network device 103 shown in the figure.

[0086] Among them, user equipment (UE) 101 can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in future 5G network or terminal device in future evolved PLMN network, etc.

[0087] The first network device 102 or the second network device 103 can be an access network device (or access point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment for controlling the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, future PLMN networks, or NR base stations. Network device 102 can be a wearable device or an in-vehicle device. Network device 102 can also be a communication chip with a communication module.

[0088] For example, the first network device 102 or the second network device 103 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0089] In a scenario where the primary cell (Pcell) corresponding to user equipment 101 dynamically switches between cells to achieve energy conservation, before the primary cell shuts down, user equipment under the primary cell needs to switch to the new cell through a handover procedure. However, the handover procedure incurs significant overhead. For example, in the simplest non-contention-based handover method, user equipment 101 first needs to initiate random access on the allocated Physical Random Access Channel (PRACH) resource, and then detect the random access response (RAR), which contains various information related to accessing the new cell. If a contention-based handover method is used, the handover overhead will be even greater. Therefore, it is necessary to address the problem of excessive network and user equipment overhead caused by the handover procedure in this scenario.

[0090] This disclosure provides a method for transmitting configuration information, referring to... Figure 2 , Figure 2 This is a method for transmitting configuration information according to an exemplary embodiment, such as... Figure 2 As shown, the method includes steps S201 to S202, specifically:

[0091] In step S201, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0092] In step S202, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell.

[0093] In some possible implementations, the present disclosure is applied to a scenario where the first main cell is dynamically turned off due to energy saving. Step S201 is executed before the first main cell is turned off, that is, before the first main cell enters a dormant state.

[0094] In some possible implementations, user equipment 101 may be configured with multiple cells as serving cells, including a primary cell (Pcell) and one or more secondary cells (Scell). User equipment 101 uses the same Cell Radio Network Temporary Identifier (C-RNTI) in the primary cell and the multiple secondary cells.

[0095] Among them, multiple cells serving as service cells have been connected to user equipment 101, and user equipment 101 has obtained uplink and downlink synchronization in each cell serving the service cells.

[0096] In some possible implementations, the first primary cell refers to the original primary cell of user equipment 101, i.e., the dynamically shut-down primary cell; the network device corresponding to the first primary cell is denoted as the first network device 102. The second primary cell refers to the new primary cell configured for user equipment 101 by the first network device 102 corresponding to the original primary cell. The first network device 102 determines a first secondary cell from at least one secondary cell of the serving cell and configures the first secondary cell as the second primary cell. The network device corresponding to each secondary cell is denoted as the second network device 103.

[0097] In some possible implementations, the configuration information may include instructions to configure the first secondary cell as the new primary cell, as well as resource configurations for the first secondary cell, such as broadcast message configuration, PRACH configuration, mobility measurement configuration, etc. This allows the user equipment 101 to perform a new primary cell configuration so that the user equipment can perform service transmissions in the second primary cell when the first primary cell is shut down.

[0098] In one example, the configuration information includes the identifier of the first secondary cell.

[0099] In this embodiment of the present disclosure, the first network device 102 may send configuration information to the user equipment 101 to configure the first secondary cell in the serving cell as the second primary cell. Thus, when the first primary cell is shut down, the first secondary cell that has established a connection with the user equipment 101 can be configured as the new primary cell, reducing unnecessary handover procedures for the user equipment 101 and effectively reducing the overhead of the user equipment 101.

[0100] Furthermore, in this embodiment of the disclosure, when the configuration information includes the resource configuration of the first secondary cell, the user equipment 101 can obtain the resource configuration information of the second primary cell before switching to the second primary cell, reducing the signaling interaction after the switch and further saving the time overhead of the user equipment 101 in obtaining the resource configuration of the second primary cell.

[0101] This disclosure provides a method for transmitting configuration information, referring to... Figure 3 , Figure 3 This is a method for transmitting configuration information according to an exemplary embodiment, such as... Figure 3 As shown, the method includes steps S301 to S304, specifically:

[0102] In step S301, user equipment 101 sends first auxiliary information to first network device 102. The first auxiliary information is used to indicate the characteristic information that user equipment 101 recommends as the primary cell for the secondary cell.

[0103] In step S302, the first network device 102 determines the first secondary cell among at least one secondary cell based on the received first auxiliary information.

[0104] In step S303, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0105] In step S304, user equipment 101 receives configuration information sent by the first network device 102.

[0106] In some possible implementations, user equipment 101 may recommend to the first network device 102 the frequency band or identification information of a secondary cell that can serve as the primary cell.

[0107] In some possible implementations, the first network device 102 may refer to the first auxiliary information reported by the user equipment 101 to determine a more suitable first auxiliary cell as the new primary cell, i.e., the second primary cell.

[0108] In one example, the first auxiliary information reported by user equipment 101 indicates that the operating frequency band of the secondary cell recommended by user equipment 101 as the primary cell is band 1. Based on the first auxiliary information, the first network device 102 determines that the secondary cells in band 1 of the user equipment's serving cell are Scell ​​1 and Scell ​​2.

[0109] In this example, the first network device 102 can determine the first secondary cell based on the load conditions of Scell ​​1 and Scell ​​2. For example, if the load of Scell ​​1 is greater than that of Scell ​​2, Scell ​​1 serves as the secondary cell for user equipment 101 while also serving as the primary cell for other user equipment. The first network device 102 can determine that Scell ​​2, with a smaller load, is the first secondary cell and configure Scell ​​2 as the new primary cell.

[0110] In some possible implementations, the configuration information may include not only instructions to configure the first secondary cell as the new primary cell, but also resource configurations of the first secondary cell, such as broadcast message configuration, PRACH configuration, mobility measurement configuration, etc.

[0111] In one example, the configuration information includes the identifier of the first secondary cell.

[0112] In this embodiment of the disclosure, user equipment 101 recommends characteristic information that can be used as a primary cell to the first network device 102 by reporting first auxiliary information to the first network device 102. Thus, the first network device 102 can refer to the first auxiliary information, which helps to determine a more suitable first auxiliary cell as the new primary cell, i.e., the second primary cell.

[0113] Furthermore, in this embodiment of the disclosure, when the configuration information includes the resource configuration of the first secondary cell, the user equipment 101 can obtain the resource configuration information of the second primary cell before switching to the second primary cell, reducing the signaling interaction after the switch and further saving the time overhead of the user equipment 101 in obtaining the resource configuration of the second primary cell.

[0114] This disclosure provides a method for transmitting configuration information, referring to... Figure 4 , Figure 4 This is a method for transmitting configuration information according to an exemplary embodiment, such as... Figure 4 As shown, the method includes steps S401 to S404, specifically:

[0115] In step S401, user equipment 101 sends second auxiliary information to first network device 102. The second auxiliary information includes channel quality parameters between user equipment 101 and at least one secondary cell.

[0116] In step S402, the first network device 102 determines the first secondary cell among at least one secondary cell based on the received second auxiliary information.

[0117] In step S403, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0118] In step S404, user equipment 101 receives configuration information sent by the first network device 102.

[0119] In some possible implementations, the network device corresponding to each secondary cell is a second network device 102. Therefore, the second auxiliary information can characterize the channel quality parameters between the user equipment 101 and the second network device 102 corresponding to each secondary cell.

[0120] In some possible implementations, channel quality parameters include Reference Signal Receiving Power (RSRP) or Received Signal Strength Indication (RSSI).

[0121] In some possible implementations, the first network device 102 may refer to the second auxiliary information reported by the user equipment 101 to determine the first auxiliary cell with better channel quality among the auxiliary cells, and use it as the new primary cell, i.e., the second primary cell.

[0122] In some possible implementations, the configuration information may include not only instructions to configure the first secondary cell as the new primary cell, but also resource configurations of the first secondary cell, such as broadcast message configuration, PRACH configuration, mobility measurement configuration, etc.

[0123] In one example, the configuration information includes the identifier of the first secondary cell.

[0124] In this embodiment, user equipment 101 reports channel quality parameters between itself and each secondary cell by reporting second auxiliary information to first network device 102. Thus, first network device 102 can refer to the first auxiliary information to determine the first secondary cell with better channel quality as the new primary cell, effectively ensuring the service transmission quality of the first primary cell in its dormant state.

[0125] Furthermore, in this embodiment of the disclosure, when the configuration information includes the resource configuration of the first secondary cell, the user equipment 101 can obtain the resource configuration information of the second primary cell before switching to the second primary cell, reducing the signaling interaction after the switch and further saving the time overhead of the user equipment 101 in obtaining the resource configuration of the second primary cell.

[0126] This disclosure provides a method for transmitting configuration information, the method including steps S401' to S404', specifically:

[0127] In step S401', user equipment 101 sends first auxiliary information and second auxiliary information to first network device 102. The first auxiliary information is used to indicate the characteristic information of the secondary cell recommended by user equipment 101 as the primary cell. The second auxiliary information includes channel quality parameters between user equipment 101 and at least one secondary cell.

[0128] In step S402', the first network device 102 determines the first secondary cell among at least one secondary cell based on the received first auxiliary information and second auxiliary information.

[0129] In step S403', the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0130] In step S404', user equipment 101 receives configuration information sent by the first network device 102.

[0131] In some possible implementations, the order in which user equipment 101 sends the first auxiliary information and the second auxiliary information is not limited. For example, the first auxiliary information may be sent first, the second auxiliary information may be sent first, or the first auxiliary information and the second auxiliary information may be sent simultaneously. As another example, the first auxiliary information and / or the second auxiliary information may be sent according to the request order indicated by the request information of the first network device 102.

[0132] In some possible implementations, the first network device 102 determines n secondary cells recommended by the user equipment 101 as primary cells based on the first auxiliary information; and then determines the secondary cell with the best channel quality parameters among the n secondary cells as the first secondary cell based on the second auxiliary information.

[0133] In some possible implementations, the first network device 102 determines n secondary cells whose channel quality parameters meet the parameter thresholds based on the second auxiliary information; and then determines the secondary cell recommended by the user equipment 101 among the n secondary cells as the first secondary cell based on the first auxiliary information.

[0134] Understandably, when making decisions by referring to the first auxiliary information and / or the second auxiliary information, the first network device 102 may still refer to other information, such as the load of the secondary cell or whether the conditions for being designated as the primary cell are met.

[0135] In this embodiment of the disclosure, the first network device 102 can comprehensively determine the first auxiliary cell by referring to the first auxiliary information and the second auxiliary information, which is beneficial to selecting a suitable first auxiliary cell with good channel quality as the new primary cell.

[0136] This disclosure provides a method for transmitting configuration information, referring to... Figure 5 , Figure 5 This is a method for transmitting configuration information according to an exemplary embodiment, such as... Figure 5 As shown, the method includes steps S501 to S504, specifically:

[0137] In step S501, the first network device 102 receives third auxiliary information sent by the second network device 103 corresponding to at least one secondary cell. The third auxiliary information is used to indicate whether the at least one secondary cell meets the setting conditions for being a primary cell.

[0138] In step S502, the first network device 102 determines the resource configuration corresponding to the first secondary cell in at least one secondary cell based on the received third auxiliary information.

[0139] In step S503, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0140] In step S504, user equipment 101 receives configuration information sent by the first network device 102.

[0141] In some possible implementations, each secondary cell corresponds to a second network device 103. The second network device 103 can inform the first network device 102 whether its corresponding secondary cell can serve as the primary cell, for the first network device 102 to make a decision based on this information.

[0142] In some possible implementations, the conditions for being designated as the primary cell are met, including at least one of the following:

[0143] Supports PRACH configuration;

[0144] It broadcasts a specific type of system message (System Information Block, SIB), such as at least one of SIB1, SIB2, SIB3, SIB4, and SIB5;

[0145] Includes the broadcast of the synchronization signaling block (SSB).

[0146] In one example, SIB1 primarily carries information related to cell access and cell selection. SIB2 primarily carries information related to common radio resource configuration, including PRACH configuration information. SIB3 carries common information related to intra-frequency, inter-frequency, and cross-system cell reselection. SIB4 carries neighbor cell information for intra-frequency cell reselection. SIB5 carries neighbor cell information for inter-frequency cell reselection.

[0147] In some possible implementations, the conditions for being designated as the primary cell are not met, such as any of the following:

[0148] PRACH configuration is not supported;

[0149] There are no broadcast system messages of certain types or all system messages;

[0150] There is no synchronization signaling block (SSB) broadcast.

[0151] In some possible implementations, the first network device 102 also receives first auxiliary information and second auxiliary information sent by the user equipment 101.

[0152] In some possible implementations, the first network device 102 determines the first auxiliary cell based on the third auxiliary information, combined with the first auxiliary information and / or the second auxiliary information.

[0153] In some possible implementations, after determining that the conditions for being a primary cell are met based on the third auxiliary information, the first network device 102 further filters the primary secondary cell by combining the first auxiliary information and / or the second auxiliary information.

[0154] In one example, the first network device 102 determines n secondary cells that can serve as the primary cell based on third auxiliary information. From these n secondary cells, a first secondary cell is determined by combining the first auxiliary information and / or the second auxiliary information. For example, from these n secondary cells, the first network device 102 determines a subset of secondary cells recommended by the user equipment 101 as potential primary cells based on the first auxiliary information, and then determines the secondary cell with the best channel quality among this subset of secondary cells as the first secondary cell based on the second auxiliary information.

[0155] In some possible implementations, the first network device 102 may also combine the first auxiliary information and / or the second auxiliary information to filter out at least one secondary cell, and then combine the third auxiliary information to determine the first secondary cell among the at least one secondary cell.

[0156] In this embodiment, the second network device 103 informs the first network device 102 whether the secondary cell corresponding to the second network device 103 meets the conditions to be the primary cell by reporting third auxiliary information to the first network device 102. Thus, the first network device 102 can refer to the third auxiliary information to determine a suitable secondary cell as the new primary cell.

[0157] This disclosure provides a method for receiving configuration information, executed by user equipment 101. (Refer to...) Figure 6 , Figure 6 This is a method for receiving configuration information according to an exemplary embodiment, such as... Figure 6 As shown, the method includes step S601, specifically:

[0158] In step S601, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0159] In some possible implementations, the present disclosure is applied to a scenario where the first main cell is dynamically turned off due to energy saving. Step S201 is executed before the first main cell is turned off, that is, before the first main cell enters a dormant state.

[0160] In some possible implementations, user equipment 101 may be configured with multiple cells as serving cells, including a primary cell (Pcell) and one or more secondary cells (Scells). User equipment 101 uses the same C-RNTI in the primary cell and the multiple secondary cells.

[0161] Among them, multiple cells serving as service cells have been connected to user equipment 101, and user equipment 101 has obtained uplink and downlink synchronization in each cell serving the service cells.

[0162] In some possible implementations, the first primary cell refers to the original primary cell of user equipment 101, i.e., the primary cell that is dynamically shut down; the second primary cell refers to the new primary cell that the first network device 102 configures for user equipment 101 after the first primary cell is dynamically shut down, and the new primary cell is determined from at least one secondary cell.

[0163] The network device corresponding to the first primary cell is designated as the first network device 102, and the network device corresponding to each secondary cell is designated as the second network device 103.

[0164] In some possible implementations, the configuration information may include instructions to configure the first secondary cell as the new primary cell, as well as the resource configuration of the first secondary cell. This allows the user equipment 101 to perform a new primary cell configuration so that the user equipment can perform service transmissions in the second primary cell when the first primary cell is shut down.

[0165] In this embodiment of the disclosure, user equipment 101 can obtain the first secondary cell configured as the second primary cell in the serving cell based on the configuration information sent by the first network device 102. Therefore, when the first primary cell is shut down, the first secondary cell that has established a connection with user equipment 101 can be configured as the new primary cell, thereby reducing unnecessary handover procedures for user equipment 101 and effectively reducing the overhead of user equipment 101.

[0166] This disclosure provides a method for receiving configuration information, executed by user equipment 101. (Refer to...) Figure 7 , Figure 7 This is a method for receiving configuration information according to an exemplary embodiment, such as... Figure 7 As shown, the method includes steps S701 to S702, specifically:

[0167] In step S701, user equipment 101 sends first auxiliary information to first network device 102. The first auxiliary information is used to indicate the characteristic information that user equipment 101 recommends as the primary cell for the secondary cell.

[0168] In step S702, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0169] In some possible implementations, user equipment 101 may recommend to the first network device 102 the frequency band or identification information of a secondary cell that can serve as the primary cell.

[0170] In some possible implementations, the first network device 102 determines the resource configuration of the first secondary cell based on the first auxiliary information, so as to send configuration information containing the resource configuration of the first secondary cell to the user equipment 101.

[0171] In this embodiment of the disclosure, user equipment 101 recommends characteristic information that can be used as a primary cell to the first network device 102 by reporting first auxiliary information to the first network device 102. Thus, the first network device 102 can refer to the first auxiliary information, which helps to determine a more suitable first secondary cell as the new primary cell.

[0172] This disclosure provides a method for receiving configuration information, executed by a user equipment 101. The method includes steps S701 to S702, wherein the feature information includes at least one of the following:

[0173] Operating frequency band;

[0174] Identification information.

[0175] In some possible implementations, the recommended operating frequency band for user equipment 101 may correspond to the preferred frequency band for service transmission of user equipment 101.

[0176] In some possible implementations, the recommended operating frequency band for user equipment 101 may correspond to one or more secondary cells.

[0177] In one example, user equipment 101 recommends the secondary cell on band 1 as the first secondary cell, and the secondary cell on band 1 is Scell ​​1.

[0178] In one example, user equipment 101 recommends a secondary cell on band 1 as the first secondary cell, and the secondary cells on band 1 include Scell ​​1 and Scell ​​2.

[0179] In some possible implementations, the identification information can be the physical layer identifier of the cell or the cell index identifier. Among them, the cell index identifier occupies fewer bits.

[0180] In one example, user equipment 101 recommends the secondary cell (serving cell 1) with cell index 1 as the first secondary cell.

[0181] In some possible implementations, the first network device 102 selects the first secondary cell with reference to the first auxiliary information.

[0182] In this embodiment of the disclosure, the user equipment 101 reports characteristic information that the first network device 102 can possess as the primary cell, such as frequency band and cell identifier, to provide the first network device 102 with reference first auxiliary information.

[0183] This disclosure provides a method for receiving configuration information, executed by user equipment 101. (Refer to...) Figure 8 , Figure 8 This is a method for receiving configuration information according to an exemplary embodiment, such as... Figure 8 As shown, the method includes steps S801 to S802, specifically:

[0184] In step S801, user equipment 101 sends second auxiliary information to first network device 102. The second auxiliary information includes channel quality parameters between user equipment 101 and at least one secondary cell.

[0185] In step S802, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0186] In some possible implementations, the network device corresponding to each secondary cell is a second network device 102. Therefore, the second auxiliary information can characterize the channel quality parameters between the user equipment 101 and the second network device 102 corresponding to each secondary cell.

[0187] In some possible implementations, channel quality parameters include RSRP or RSSI.

[0188] In some possible implementations, the first network device 102 determines the resource configuration of the first secondary cell based on the second auxiliary information, so as to send configuration information containing the resource configuration of the first secondary cell to the user equipment 101.

[0189] In this embodiment, user equipment 101 reports channel quality parameters between itself and each secondary cell by reporting second auxiliary information to first network device 102. Thus, first network device 102 can refer to the first auxiliary information to determine the first secondary cell with better channel quality as the new primary cell, effectively ensuring the service transmission quality of the first primary cell in its dormant state.

[0190] This disclosure provides a method for receiving configuration information, which is executed by user equipment 101.

[0191] The method includes steps S701' to S702, specifically:

[0192] In step S701', in response to receiving the request information from the first network device 102, the user equipment 101 sends first auxiliary information to the first network device 102. The first auxiliary information is used to indicate the characteristic information that the user equipment 101 recommends as the primary cell for the secondary cell.

[0193] In step S702, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0194] Alternatively, the method includes steps S801' to S802, specifically:

[0195] In step S801', in response to receiving the request information from the first network device 102, the user equipment 101 sends second auxiliary information to the first network device 102. The second auxiliary information includes channel quality parameters between the user equipment 101 and at least one secondary cell.

[0196] In step S802, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0197] Alternatively, in response to receiving a request from the first network device 102, the user equipment 101 sends first auxiliary information and second auxiliary information to the first network device 102.

[0198] In some possible implementations, the first auxiliary information and the second auxiliary information correspond to different request information, or to different fields in the same request information.

[0199] In some possible implementations, after receiving the request information, the user equipment 101 reports the first auxiliary information or the second auxiliary information to the first network device 102; or after receiving the request information, it reports the first auxiliary information and the second auxiliary information.

[0200] In some possible implementations, the first network device 102 determines the first auxiliary cell based on at least one of the first auxiliary information and the second auxiliary information, with reference to a decision.

[0201] In this embodiment of the disclosure, the user equipment 101 reports corresponding auxiliary information to the first network device 102 according to the request information of the first network device 102, so as to provide recommendations or references for the first network device 102 and determine the first auxiliary cell that can be used as the new primary cell more efficiently or reasonably.

[0202] This disclosure provides a method for receiving configuration information, executed by user equipment 101. The method includes steps S601 to S602, specifically:

[0203] In step S601, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0204] In step S602, user equipment 101 sends indication information to first network device 102, the indication information being used to indicate that the first secondary cell has been successfully configured as the second primary cell.

[0205] In some possible implementations, the configuration information may include instructions to configure the first secondary cell as the new primary cell and the resource configuration of the first secondary cell. User equipment 101 configures the new primary cell according to the configuration information, and after successful configuration, reports instruction information to the first network device 102.

[0206] In some possible implementations, after receiving an instruction, the first network device 102 can dynamically shut down and enter a sleep state to save energy. At this time, the first primary cell corresponding to the first network device 102 will also shut down and enter a sleep state.

[0207] In this embodiment of the disclosure, after the user equipment 101 successfully configures a new primary cell, it can promptly report to the first network device 102 so that the first network device 102 can shut down in time to save power.

[0208] This disclosure provides a method for receiving configuration information, executed by user equipment 101. The method includes steps S601 and S603, specifically:

[0209] In step S601, user equipment 101 receives configuration information sent by the first network device 102 corresponding to the first primary cell. The configuration information is used to indicate that the first secondary cell in at least one secondary cell is configured as the second primary cell. The serving cell of user equipment 101 includes the first primary cell and at least one secondary cell.

[0210] In step S603, based on the configuration information, user equipment 101 performs service transmission with the second main cell.

[0211] In some possible implementations, the configuration information may include instructions to configure the first secondary cell as the new primary cell, as well as the resource configuration of the first secondary cell. This allows the user equipment 101 to perform the new primary cell configuration.

[0212] In some possible implementations, after the second primary cell is successfully configured, the second primary cell may send Radio Resource Control (RRC) connection reconfiguration information to the user equipment 101 so that the user equipment 101 can be configured with RRC configuration information that matches the new primary cell.

[0213] In some possible implementations, after the user equipment 101 completes the RRC connection reconfiguration of the new primary cell, it can perform service transmission with the second primary cell, that is, perform service transmission with the second network device 103 corresponding to the second primary cell.

[0214] In this embodiment of the disclosure, when the first primary cell is shut down, the user equipment 101 can omit the handover process and perform service transmission with the new primary cell in the serving cell, thereby reducing the overhead of the user equipment 101.

[0215] This disclosure provides a method for sending configuration information, executed by a first network device 102. (Refer to...) Figure 9 , Figure 9 This is a method for sending configuration information according to an exemplary embodiment, such as... Figure 9 As shown, the method includes step S901, specifically:

[0216] In step S901, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0217] In some possible implementations, the configuration information may include instructions to configure the first secondary cell as the new primary cell and the resource configuration of the first secondary cell.

[0218] In some possible implementations, user equipment 101 may be configured with multiple cells as serving cells, including a primary cell (Pcell) and one or more secondary cells (Scells). User equipment 101 uses the same C-RNTI in the primary cell and the multiple secondary cells.

[0219] Among them, multiple cells serving as service cells have been connected to user equipment 101, and user equipment 101 has obtained uplink and downlink synchronization in each cell serving the service cells.

[0220] In some possible implementations, the first primary cell refers to the original primary cell of user equipment 101, i.e., the primary cell that is dynamically shut down; the second primary cell refers to the new primary cell that the first network device 102 configures for user equipment 101 after the first primary cell is dynamically shut down, and the new primary cell is determined from at least one secondary cell.

[0221] The network device corresponding to the first primary cell is designated as the first network device 102, and the network device corresponding to each secondary cell is designated as the second network device 103.

[0222] In this embodiment of the present disclosure, the first network device 102 may send configuration information to the user equipment 101 to configure the first secondary cell in the serving cell as the second primary cell. Thus, when the first primary cell is shut down, the first secondary cell that has established a connection with the user equipment 101 can be configured as the new primary cell, reducing unnecessary handover procedures for the user equipment 101 and effectively reducing the overhead of the user equipment 101.

[0223] This disclosure provides a method for sending configuration information, executed by a first network device 102. (Refer to...) Figure 10 , Figure 10 This is a method for sending configuration information according to an exemplary embodiment, such as... Figure 10 As shown, the method includes steps S1001 to S1003, specifically:

[0224] In step S1001, the first network device 102 receives first auxiliary information sent by the user equipment 101. The first auxiliary information is used to indicate the characteristic information of the secondary cell recommended by the user equipment 101 as the primary cell.

[0225] In step S1002, the first network device 102 determines the first secondary cell among at least one secondary cell based on the first auxiliary information.

[0226] In step S1003, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0227] In some possible implementations, the feature information includes at least one of the following:

[0228] Operating frequency band;

[0229] Identification information.

[0230] In some possible implementations, the first network device 102 determines the resource configuration of the first secondary cell based on the first auxiliary information, so as to send configuration information containing the resource configuration of the first secondary cell to the user equipment 101.

[0231] In some possible implementations, the first network device 102, based on the first auxiliary information, selects the secondary cell recommended by the user equipment 101 as the first secondary cell, and uses it as the new primary cell.

[0232] In some possible implementations, the first network device 102 selects the cell with the lowest load from at least one secondary cell recommended by the user equipment 101 as the first secondary cell, based on the first auxiliary information, so as to serve as the new primary cell.

[0233] In this embodiment of the disclosure, the first network device 102 learns the characteristic information that the first network device 102 recommends as a primary cell based on the first auxiliary information reported by the user equipment 101. Therefore, the first network device 102 can refer to the first auxiliary information, which is beneficial for determining a more suitable first secondary cell as the new primary cell.

[0234] This disclosure provides a method for sending configuration information, executed by a first network device 102. (Refer to...) Figure 11 , Figure 11 This is a method for sending configuration information according to an exemplary embodiment, such as... Figure 11 As shown, the method includes steps S1101 to S1103, specifically:

[0235] In step S1101, the first network device 102 receives second auxiliary information sent by the user equipment 101. The second auxiliary information includes channel quality parameters between the user equipment 101 and at least one secondary cell.

[0236] In step S1102, the first network device 102 determines the first secondary cell among at least one secondary cell based on the second auxiliary information.

[0237] In step S1103, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0238] Alternatively, the method includes steps S1101' to S1103', specifically:

[0239] In step S1101', the first network device 102 receives first auxiliary information and second auxiliary information sent by the user equipment 101. The first auxiliary information is used to indicate the characteristic information of the secondary cell recommended by the user equipment 101 as the primary cell. The second auxiliary information includes channel quality parameters between the user equipment 101 and at least one secondary cell.

[0240] In step S1102', the first network device 102 determines the first secondary cell among at least one secondary cell based on the first auxiliary information and the second auxiliary information.

[0241] In step S1103', the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0242] In some possible implementations, channel quality parameters include RSRP or RSSI.

[0243] In some possible implementations, the first network device 102 may refer to the second auxiliary information reported by the user equipment 101 to determine the first auxiliary cell with better channel quality among the auxiliary cells, and use it as the new primary cell, i.e., the second primary cell.

[0244] In some possible implementations, the first network device 102 determines n secondary cells recommended by the user equipment 101 as primary cells based on the first auxiliary information; and then determines the secondary cell with the best channel quality parameters among the n secondary cells as the first secondary cell based on the second auxiliary information.

[0245] In some possible implementations, the first network device 102 determines n secondary cells whose channel quality parameters meet the parameter thresholds based on the second auxiliary information; and then determines the secondary cell recommended by the user equipment 101 among the n secondary cells as the first secondary cell based on the first auxiliary information.

[0246] Understandably, when making decisions by referring to the first auxiliary information and / or the second auxiliary information, the first network device 102 may still refer to other information, such as the load of the secondary cell or whether the conditions for being designated as the primary cell are met.

[0247] In this embodiment of the disclosure, the first network device 102 obtains the channel quality parameters between the user equipment 101 and each secondary cell based on the method of the user equipment 101 reporting the second auxiliary information. Therefore, the first network device 102 can refer to the first auxiliary cell with better channel quality to determine it as the new primary cell, effectively ensuring the service transmission quality of the first primary cell in its dormant state.

[0248] This disclosure provides a method for sending configuration information, executed by a first network device 102. The method includes step S1000:

[0249] In step S1000, the first network device 102 sends a request message to the user equipment 101. The request message is used to instruct the user equipment 101 to obtain auxiliary information, which includes first auxiliary information and / or second auxiliary information.

[0250] In this embodiment, steps S1001 to S1003 or steps S1101 to S1103 may also be included, with step S1000 being executed before step S1001 or S1101.

[0251] In some possible implementations, the first auxiliary information is used to instruct the user equipment 101 on the characteristic information that the secondary cell recommended as the primary cell possesses.

[0252] In some possible implementations, the second auxiliary information includes channel quality parameters between user equipment 101 and at least one secondary cell.

[0253] In this embodiment of the disclosure, the first network device 102 requests the user equipment 101 to report auxiliary information for reference by sending a request message, so as to more efficiently or reasonably determine the first auxiliary cell that can be used as the new primary cell.

[0254] This disclosure provides a method for sending configuration information, executed by a first network device 102. The method includes steps S901 to S902, specifically:

[0255] In step S901, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0256] In step S902, the first network device 102 receives an indication message sent by the user equipment 101, the indication message being used to indicate that the first secondary cell has been successfully configured as the second primary cell.

[0257] In some possible implementations, user equipment 101 configures a new primary cell according to configuration information, and after successful configuration, reports instruction information to the first network device 102.

[0258] In some possible implementations, after receiving an instruction, the first network device 102 can dynamically shut down and enter a sleep state to save energy. At this time, the first primary cell corresponding to the first network device 102 will also shut down and enter a sleep state.

[0259] In some possible implementations, after receiving the instruction information or determining the resource configuration of the first secondary cell, the first network device 102 and the second network device 103 corresponding to the first secondary cell can perform data forwarding.

[0260] For example, the first primary cell sends the service data that has not been fully transmitted between it and the user equipment 101 to the second primary cell, and the second primary cell continues the transmission with the user equipment 101.

[0261] In this embodiment of the disclosure, after the first network device 102 learns that the user equipment 101 has successfully configured a new primary cell, it can promptly turn off power saving mode.

[0262] This disclosure provides a method for sending configuration information, executed by a first network device 102. (Refer to...) Figure 12 , Figure 12 This is a method for sending configuration information according to an exemplary embodiment, such as... Figure 12 As shown, the method includes steps S1201 to S1203, specifically:

[0263] In step S1201, the first network device 102 receives third auxiliary information sent by the second network device 103 corresponding to at least one secondary cell. The third auxiliary information is used to indicate whether the at least one secondary cell meets the setting conditions for being a primary cell.

[0264] In step S1202, the first network device 102 determines the resource configuration corresponding to the first secondary cell in at least one secondary cell based on the third auxiliary information.

[0265] In step S1203, the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0266] Alternatively, the method includes steps S1201' to S1204', specifically:

[0267] In step S1201', the first network device 102 receives third auxiliary information sent by the second network device 103 corresponding to at least one secondary cell. The third auxiliary information is used to indicate whether the at least one secondary cell meets the setting conditions for being a primary cell.

[0268] In step S1202', the first network device 102 receives first auxiliary information and second auxiliary information sent by the user equipment 101. The first auxiliary information is used to indicate the characteristic information of the secondary cell recommended by the user equipment 101 as the primary cell. The second auxiliary information includes channel quality parameters between the user equipment 101 and at least one secondary cell.

[0269] In step S1203', the first network device 102 determines the first secondary cell among at least one secondary cell based on the third auxiliary information and at least one of the first auxiliary information and the second auxiliary information.

[0270] In step S1204', the first network device 102 sends configuration information to the user equipment 101. The configuration information is used to instruct the first secondary cell in at least one secondary cell to be configured as the second primary cell. The serving cell of the user equipment 101 includes the first primary cell and at least one secondary cell.

[0271] In some possible implementations, each secondary cell corresponds to a second network device 103. The second network device 103 can inform the first network device 102 whether its corresponding secondary cell can serve as the primary cell, for the first network device 102 to make a decision based on this information.

[0272] In some possible implementations, the conditions for being designated as the primary cell are not met, such as any of the following:

[0273] PRACH configuration is not supported;

[0274] There are no broadcast system messages of certain types or all system messages;

[0275] There is no synchronization signaling block (SSB) broadcast.

[0276] In some possible implementations, the first network device 102 may determine the first auxiliary cell based on at least one of the first auxiliary information, the second auxiliary information, and the third auxiliary information.

[0277] In some possible implementations, after determining that the conditions for being a primary cell are met based on the third auxiliary information, the first network device 102 further filters the primary secondary cell by combining the first auxiliary information and / or the second auxiliary information.

[0278] In one example, the first network device 102 determines n secondary cells that can serve as the primary cell based on third auxiliary information. From these n secondary cells, a first secondary cell is determined by combining the first auxiliary information and / or the second auxiliary information. For example, from these n secondary cells, the first network device 102 determines a subset of secondary cells recommended by the user equipment 101 as potential primary cells based on the first auxiliary information, and then determines the secondary cell with the best channel quality among this subset of secondary cells as the first secondary cell based on the second auxiliary information.

[0279] In this embodiment of the disclosure, the first network device 102 determines whether the secondary cell corresponding to the second network device 103 meets the conditions to be the primary cell based on the third auxiliary information reported by the second network device 103.
