Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a carrier configuration method and related devices. Background Art

[0002] In the Long Term Evolution (LTE) network or the 4th generation (4G) mobile communication network, the Carrier Aggregation (CA) technology is introduced to aggregate multiple continuous or discontinuous spectrums to ensure the large bandwidth demand of mobile communication and improve the communication rate. In the New Radio (NR) network or the 5th generation (5G) mobile communication network, the Supplementary uplink (SUL) technology is proposed to provide a supplementary uplink to ensure the coverage of uplink signals at high frequencies.

[0003] In LTE network or 4G network, CA is a technology that connects and communicates an electronic device (or user equipment (UE)) through multiple cells (Cell) and network equipment. Among them, one cell serves as the primary cell (PCell) of the electronic device, and other cells serve as secondary cells (SCell) of the electronic device. The network device can configure DL (downlink) CA for the electronic device, and the cell based on the DL CA state is the SCell. In NR network or 5G network, in one cell configured by UE, two uplink carriers can be configured for one downlink carrier, of which one uplink carrier serves as a supplementary SUL, and the SUL can be configured for PCell or SCell.

[0004] How to process SUL operation and CA operation on a carrier supporting SUL operation is a technical problem that needs to be solved urgently. Summary of the invention

[0072] In order to facilitate understanding of the embodiments of the present application, the following is a brief introduction to the relevant terms involved in this article.

[0073] 1. Time division duplex (TDD): A duplex communication technology of a communication system that is used to separate the receiving and transmitting channels, i.e., the uplink and downlink. In a communication system using the TDD mode, the uplink and downlink use the same frequency domain resources, and the uplink and downlink are distinguished by different time domain resources. In LTE, TDD has 7 configurations. A frame has 10 subframes. If D represents the downlink subframe and U represents the uplink subframe, the arrangement order of D and U is fixed in each configuration. Within a cell, the TDD configuration can be semi-statically configured or statically configured. In NR, TDD can also be called dynamic TDD. As the smallest schedulable time unit, the ratio of different time slot types in each frame can be changed dynamically for more flexible scheduling, and the number of time slots contained in each frame is different as the subcarrier spacing changes. According to the different time slot types, a time slot can be a pure uplink time slot, a pure downlink time slot, an uplink dominated time slot, or a downlink dominated time slot. Among them, all symbols in pure uplink time slots are used as uplink symbols; all symbols in pure downlink time slots are downlink symbols; the number of uplink symbols in uplink-dominated time slots is greater than the number of downlink symbols; the number of downlink symbols in downlink-dominated time slots is greater than the number of uplink symbols; in addition, a protection band can be set between the uplink and downlink symbols.

[0074] 2. Frequency division duplex (FDD): A duplex communication technology used in communication systems to separate the receiving and transmitting channels, i.e., uplink and downlink. In a communication system using the FDD mode, the uplink and downlink use the same time domain resources, and different frequency domain resources are used to distinguish the uplink and downlink. For example, the uplink frequency range is different from the downlink frequency range.

[0075] 3. Time domain resources: resources in the time domain. Time domain resources can be uplink time domain resources, downlink time domain resources or flexible time domain resources. In NR, time domain resource configuration methods can include at least 3 types, such as cell-level semi-static configuration method, user-level semi-static configuration method and user-level dynamic configuration method.

[0076] 4. Flexible time domain resources: can be understood as time domain resources that are not configured as uplink time domain resources or downlink time domain resources. Flexible time domain resources can be used as a guard period (GP) between uplink time domain resources and downlink time domain resources. Flexible time domain resources can be further configured as uplink time domain resources or downlink time domain resources. In NR, the cell-level semi-static configuration method can configure uplink time domain resources, downlink time domain resources and flexible time domain resources for electronic devices in the cell through cell-level RRC messages; for the flexible time domain resources configured by the cell-level semi-static configuration method, the user-level semi-static method can configure the flexible time domain resources as uplink time domain resources or downlink time domain resources for an electronic device through a user-level RRC message, or not configure the flexible time domain resources (or at this time it can be understood that the user-level semi-static method still configures the flexible time domain resources as flexible time domain resources); for the flexible time domain resources configured by the cell-level semi-static configuration method or the user-level semi-static configuration method, the user-level dynamic configuration method can configure the flexible time domain resources as uplink time domain resources or downlink time domain resources for an electronic device in the form of DCI, or not configure the flexible time domain resources (or at this time it can be understood that the user-level dynamic method still configures the flexible time domain resources as flexible time domain resources). Flexible time domain resources can be called unknown time domain resources.

[0077] 5. Transmission time domain resources: can be understood as time domain resources configured for transmission, where transmission may include uplink transmission and downlink transmission, for example, uplink transmission may include one or more of a channel sounding reference signal (SRS), a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH). When a time domain resource is configured as an uplink time domain resource or a flexible time domain resource, the uplink time domain resource or the flexible time domain resource may be further configured for uplink transmission. For example, an uplink transmission time domain resource may be configured as a PUSCH time domain resource, an SRS time domain resource or a PUCCH time domain resource, and a flexible time domain resource may be configured as an SRS time domain resource, etc.

[0078] 6. Slot: The minimum scheduling unit of time domain resources. In NR, the format of a time slot may include 14 OFDM symbols, and the CP of each OFDM symbol is a normal CP; or, the format of a time slot may include 12 OFDM symbols, and the CP of each OFDM symbol is an extended CP; or, the format of a time slot may include 7 OFDM symbols, and the CP of each OFDM symbol is a normal CP. The OFDM symbols in a time slot can be used entirely for uplink transmission; can be used entirely for downlink transmission; or can be used partially for downlink transmission, partially for uplink transmission, and partially reserved for non-transmission. It should be understood that the above examples are for illustrative purposes only and should not constitute any limitation to this application. For the sake of system forward compatibility, the time slot format is not limited to the above examples. In NR, according to different subcarrier spacings, 1ms can include different numbers of time slots. For example, when the subcarrier spacing is 15kHz, 1ms includes 1 time slot, which occupies 1ms; when the subcarrier spacing is 30kHz, 1ms includes 2 time slots, each of which occupies 0.5ms.

[0079] 7. Symbol: The smallest unit of time domain resources. The embodiments of the present application do not limit the time length of a symbol. The length of a symbol may be different for different subcarrier spacings. Symbols may include uplink symbols and downlink symbols. As an example and not a limitation, an uplink symbol may be called a single carrier frequency division multiple access (SC-FDMA) symbol or an orthogonal frequency division multiple access (OFDM) symbol; a downlink symbol may be called an OFDM symbol.

[0080] In the embodiment of the present application, the network device 100 and the electronic device 200 can communicate via the TDD transmission mode, and the uplink transmission and the downlink transmission use different time domain resources; the network device 100 and the electronic device 200 can also communicate via the FDD transmission mode, and the uplink and downlink transmissions use the same time domain resources, and the uplink and downlink transmissions are distinguished by different frequency domain resources. The embodiments of the present application are described below by taking the network device 100 and the electronic device 200 communicating via the TDD transmission mode as an example.

[0081] Figure 2 The communication system shown supports a supplementary uplink (SUL) scenario. Figure 2 is a schematic diagram of a SUL scenario. Figure 2 As shown, the network device 100 can provide two uplink carriers for the electronic device 200, namely a normal uplink (NUL) carrier and a supplementary uplink SUL carrier. Usually, the frequency band used by SUL is lower than the frequency band used by NUL, and the coverage range of SUL is larger than the coverage range of NUL, or, the frequency band used by SUL is higher than the frequency band used by NUL, and the coverage range of SUL is smaller than the coverage range of NUL.

[0082] In a possible implementation, the electronic device can Figure 3 The random access procedure shown in the figure accesses SUL. The details are as follows:

[0083] S1. An electronic device receives a system message broadcast by a network device.

[0084] Specifically, the electronic device can monitor the system information block (SIB) broadcast by the network device. Optionally, the system information SIB includes the general configuration information of the SUL. The general configuration information of the SUL includes one or more of the frequency information of the SUL, the time alignment timer (TAT), the initial configuration information of the partial bandwidth (BWP), etc. The initial configuration information of the partial bandwidth BWP includes the basic configuration information of the random access channel (RACH), the physical uplink control channel (PUCCH), and the physical uplink shared channel (PUSCH), and if the SUL band supports the TDD transmission mode, the system message SIB should include its corresponding uplink and downlink subframe ratio, if the SUL band supports the FDD transmission mode, the system message should include its corresponding uplink and downlink frequency bandwidth allocation. The root sequence number in the RACH configuration is used to determine the random access preamble, and the physical random access channel (PRACH) time-frequency information is used to indicate the time-frequency resources occupied by the PRACH.

[0085] S2. The electronic device sends Msg1 to the network device.

[0086] Specifically, the electronic device can determine a random access preamble according to the root sequence number, and send Msg1 on the time-frequency resource indicated by the PRACH time-frequency information in the system message to initiate random access. In the embodiment of the present application, the electronic device sends Msg1 to the network device, and it is considered that the electronic device initiates random access on the SUL.

[0087] S3. The network device sends Msg2 to the electronic device.

[0088] Specifically, Msg2 may be a random access response message (RAR), and Msg2 includes an uplink timing advance (TA) calculated by the network device for the electronic device.

[0089] S4. The electronic device sends Msg3 to the network device.

[0090] Specifically, the electronic device may determine the uplink timing according to the TA, and the Msg3 sent to the network device may be the first scheduled UL transmission on UL-SCH, that is, data sent by the electronic device for the first time through the uplink shared channel.

[0091] S5. The network device sends Msg4 to the electronic device.

[0092] Specifically, the network device and the electronic device can finally complete the contention resolution through Msg4. In addition, Msg4 can carry dedicated configuration information of SUL, which can indicate the specific configuration of the physical uplink control channel (PUCCH), (physical uplink shared channel, PUSCH), (sounding reference signal, SRS) of SUL, such as the configuration of different formats of PUCCH, the configuration of scrambling code, pilot, codebook, etc. of PUSCH, and the configuration of SRS.

[0093] The electronic device can also perform uplink transmission through the SUL according to the general configuration information of the SUL and the dedicated configuration information of the SUL, because the general configuration information of the SUL includes the uplink and downlink subframe ratio (if the SUL band supports the TDD transmission mode) or the uplink and downlink band bandwidth allocation (if the SUL band supports the FDD transmission mode), so the spectrum in the frequency band used by the SUL can be used flexibly, so not all time slots of this SUL band are used for uplink transmission, and SUL configuration can be introduced for some symbols / time slots and support SUL operation. Optionally, the general configuration information of the SUL and the dedicated configuration information of the SUL can be two indispensable information for the electronic device to perform uplink transmission in the SUL. Only when the electronic device obtains the general configuration information of the SUL and the dedicated configuration information of the SUL from the network device can it perform uplink transmission through the SUL.

[0094] Msg4 may be an RRC establishment message.

[0095] S6. The electronic device sends Msg5 to the network device.

[0096] Specifically, the electronic device may also establish an RRC connection with the network device and send an RRC establishment completion message to the network device, for example, Msg5 described in an embodiment of the present application.

[0097] In another possible implementation, the electronic device may also access the SUL through a non-contention random access process. For example, in the non-contention random access process, the electronic device sends Msg1 to the network device to initiate the random access process, and the electronic device receives Msg2 from the network device, and it can be considered that the electronic device has completed the random access.

[0098] The above describes the process of random access of an electronic device in an idle state in combination with steps S1-S6. In a possible implementation, an electronic device in a connected state can receive a radio resource control (RRC) message from a network device, and the RRC message can carry conventional configuration information of the SUL. After the electronic device in a connected state receives the RRC message from the network device, it needs to re-initiate random access, and the process of random access can be the same as steps S1-S5 above.

[0099] In the embodiment of the present application, the electronic device can refer to Figure 3 The process shown in the figure performs a random access process of contention, and when Msg4 is received from the network device, it is considered that the electronic device has completed random access on the SUL. Alternatively, when the electronic device completes the sending of Msg5, it is considered that the electronic device has completed random access.

[0100] Figure 2 In the scenario shown, in the prior art, the bandwidth defined as SUL is generally only used for SUL. That is, all time slots of the bandwidth are used for uplink transmission. Figure 3A The second carrier is a carrier supporting SUL, and all its time slots are configured as SUL. Time slots 0, 1, 2, and 3 in the first carrier are used for normal downlink (NDL) transmission, and time slot 4 is used for NUL transmission.

[0101] However, in order to flexibly use SUL, the TDD band can also be configured to support SUL operations. At the same time, the TDD band can also be configured with downlink resources or other resources for normal uplink. For example, refer to Figure 3B , time domain 3 of the time domain resources on the second carrier supporting SUL is used for SUL transmission, resources in time domain 0, time domain 1 and time domain 2 can be used for downlink transmission, and resources in time domain 4 can be used for uplink transmission. It can be seen that the electronic device can flexibly use the time domain resources of the second carrier supporting SUL, that is, within the TDD frequency band, for all or part of the UL symbols / time slots configured for its TDD uplink and downlink, introduce SUL configuration and support SUL operation. In other cases, refer to Figure 5B As shown, carrier 2 may also be configured to perform carrier aggregation with carrier 1. In the embodiment of the present application, a base station may flexibly configure a carrier supporting SUL through a configuration message or other message.

[0102] For ease of understanding, several optional solutions provided in the embodiments of the present application are listed below.

[0103] Solution 1

[0104] Combine the following Figure 4 Introducing plan 1, Figure 4 is a flow chart of a carrier configuration method provided in an embodiment of the present application, such as Figure 4 As shown, the method includes but is not limited to the following steps:

[0105] Step S401: The network device sends a first message to the electronic device.

[0106] Specifically, the cell determined when the electronic device initially accesses is used as the primary cell (PCell), and the electronic device establishes a radio resource control (RRC) connection in the PCell, and performs initial call establishment, RRC reconfiguration, cell switching, etc. on the PCell. The carrier corresponding to the PCell is the first carrier, and the network device and the electronic device communicate through the first carrier. In order to improve the uplink coverage gain, the second carrier is configured for the first carrier through broadcast information, and the configured second carrier is the SUL carrier of the first carrier. In order to increase the data transmission rate, the network device sends a first message including the configuration information of the secondary cell (SCell) to the electronic device. Among them, the SCell includes at least the service cell corresponding to the second carrier.

[0107] The configuration information of SCell includes carrier aggregation downlink configuration signaling and activation signaling.

[0108] Step S402: The electronic device receives a first message.

[0109] Specifically, the electronic device receives a first message sent by the network device, where the first message includes configuration information of the secondary cell.

[0110] Step S403: The electronic device configures a serving cell corresponding to the second carrier according to the configuration information of the secondary cell.

[0111] Specifically, the configuration information of the SCell includes the downlink configuration of the second carrier, and the electronic device configures the downlink of the second carrier to be aggregated with the downlink of the first carrier according to the configuration information of the SCell.

[0112] In some embodiments, before the electronic device receives the first message sent by the network device, the network device may receive the electronic device capability information sent by the electronic device, and the network device may determine whether the electronic device supports uplink carrier aggregation (UL CA) based on the electronic device capability information. If the electronic device supports UL CA, the configuration information of the secondary cell received by the electronic device may include not only the downlink configuration of the second carrier, but also the uplink configuration of the second carrier. If the electronic device does not support UL CA, the configuration information of the secondary cell received by the electronic device only includes the downlink configuration of the second carrier. In the above case, the electronic device configures the uplink of the second carrier to remain as a supplementary uplink of the first carrier according to the configuration information of the secondary cell. That is, the electronic device retains the configuration information and operation about SUL on the second carrier.

[0113] Therefore, regardless of whether the electronic device supports UL CA or not, when the electronic device configures the service cell corresponding to the second carrier according to the configuration information of the secondary cell, the service cell corresponding to the second carrier is specifically configured so that the downlink of the second carrier is transmitted with the first carrier in a carrier aggregation manner, and the uplink of the second carrier is transmitted as a supplementary uplink of the first carrier. Figure 4A As shown, the working status diagram is as follows Figure 4B As shown. Figure 4A It can be seen that the electronic device and the network device perform downlink transmission in a carrier aggregation manner, and perform uplink transmission in a NUL / SUL manner. It should be noted that before the electronic device receives the configuration information including the secondary cell, the time domain resources on the second carrier are used for SUL operation. After the electronic device receives the configuration information of the secondary cell, the resources configured for SUL transmission on the second carrier are used for SUL operation. SUL operation refers to data scheduling transmission on the SUL carrier under the premise that the SUL configuration is stored. SUL configuration refers to the relevant configuration on the SUL, including the PUSCH, PUCCH, PRACH and SRS configurations of the SUL.

[0114] from Figure 4B It can be seen that time domain 0, time domain 1 and time domain 2 on the first carrier and time domain 0, time domain 1 and time domain 2 on the second carrier are used for downlink transmission in a carrier aggregation manner, time domain 3 on the first carrier is used for downlink transmission, and time domain 4 on the first carrier is used for uplink transmission. Time domain 3 on the second carrier is used for SUL transmission, and time domain 4 on the second carrier is a flexible time domain resource.

[0115] For example, the time slot / symbol configuration diagram of the second carrier is as follows: Figure 4C As shown, the SCell configuration of the second carrier may carry the configuration of the DL row time slot / symbol and the SUL time slot / symbol of the second carrier. Figure 4CIt can be seen that SCell has a total of 10 time slots, of which the first 7 time slots, i.e., slot 0, slot 1, slot 2, slot 3, slot 4, slot 5, and slot 6 are all D symbols / time slots; the 8th time slot, i.e., the first 6 symbols / time slots of slot 7 are downlink symbols / time slots, the last 4 symbols / time slots of slot 7 are SUL symbols / time slots, the middle 4 symbols / time slots of slot 7 are flexible symbols / time slots, and the middle 4 symbols / time slots of slot 7 are used for GP; the last two time slots, i.e., slot 8 and slot 9, are all SUL symbols / time slots.

[0116] When the downlink transmission of the second carrier is configured to be transmitted in a carrier aggregation manner with the first carrier, and the resources configured for SUL transmission on the second carrier are reserved, the SUL has a corresponding downlink frequency band, so the electronic device can receive the synchronization signal and data information of the second carrier in the downlink channel of the second carrier, and use it as a downlink timing reference when the SUL on the second carrier sends, and calculate and configure an independent uplink transmission time advance (TA) for the SUL on the second carrier; the electronic device can also calculate the path loss of the uplink SUL of the second carrier according to the downlink reference signal received power RSRP of the second carrier, and calculate and configure independent transmission power control for the SUL on the second carrier; the electronic device can also receive the SSB or CSI-RS RSRP of the downlink beam of the second carrier and sort them, and use beam consistency to adjust the transmission beam of the SUL of the second carrier.

[0117] Step S404: the network device sends a third message to the electronic device.

[0118] Specifically, the third message sent by the network device to the electronic device is used to instruct the release or deactivation of the secondary cell, and the third message includes information on releasing the secondary cell or information on deactivating the secondary cell.

[0119] Step S405: The electronic device receives the third message.

[0120] Specifically, the electronic device receives a third message sent by the network device, where the third message includes information on releasing the secondary cell or deactivating the secondary cell.

[0121] Step S406: the electronic device releases or deactivates the secondary cell according to the third message, and reserves the uplink of the second carrier as a supplementary uplink of the first carrier.

[0122] Specifically, if the electronic device receives a third message sent by the network device including configuration information for releasing the secondary cell, the SCell is released according to the configuration information for releasing the secondary cell. For the relevant description of releasing the SCell, please refer to Section 5.3.10.3a of 3GPP TS36.331 V11.1.0 (2019-09); or, if the electronic device receives a third message sent by the network device including configuration information for deactivating the secondary cell, the SCell is deactivated according to the configuration information for deactivating the secondary cell. Whether deactivating the SCell or releasing the SCell, it indicates that the first carrier and the second carrier of the electronic device are not aggregated. That is, when the electronic device does not perform downlink transmission through the second carrier and the first carrier in a carrier aggregation manner, the electronic device retains the uplink of the second carrier as a supplementary uplink of the first carrier.

[0123] It should be noted that the electronic device retains the uplink of the second carrier as a supplementary uplink of the first carrier, that is, the electronic device retains the configuration information about the SUL on the second carrier. Figure 2 As shown, the working status diagram is as follows Figure 3B It is understood that the communication method between the electronic device and the network device is as follows: Figure 4A Fallback to Figure 2 As shown; correspondingly, the working status between the electronic device and the network device changes from Figure 4B Falling back to Figure 3B shown.

[0124] Solution 2

[0125] Combine the following Figure 5 Introducing Option 2: Figure 5 A carrier configuration method provided in an embodiment of the present application is as follows: Figure 5 As shown, the method includes but is not limited to the following steps:

[0126] Step S501: The network device sends a first message to the electronic device.

[0127] Specifically, please refer to step S401 for detailed description.

[0128] Step S502: The electronic device receives a first message.

[0129] Specifically, please refer to step S402 for detailed description.

[0130] Step S503: The electronic device configures a serving cell corresponding to the second carrier according to the configuration information of the secondary cell.

[0131] Specifically, the configuration information of the SCell includes the downlink configuration of the second carrier, and the electronic device configures the downlink of the second carrier to be aggregated with the downlink of the first carrier according to the configuration information of the secondary cell.

[0132] In some embodiments, before the electronic device receives the first message sent by the network device, the network device may receive electronic device capability information sent by the electronic device, and the network device may determine whether the electronic device supports uplink carrier aggregation (UL CA) according to the electronic device capability information.

[0133] If the electronic device supports UL CA, the configuration information of the secondary cell received by the electronic device includes not only the downlink configuration of the second carrier, but also the uplink configuration of the second carrier. Therefore, the electronic device deactivates the supplementary uplink of the second carrier according to the configuration information of the secondary cell, and configures the uplink of the second carrier to be aggregated with the uplink of the first carrier. That is, the second carrier is converted from being configured as the SUL of the first carrier to being deactivated SUL, and is transmitted in an aggregated manner with the uplink of the first carrier.

[0134] Schematic diagram of communication scenario between electronic devices and network devices Figure 5A As shown, the working status diagram is as follows Figure 5B As shown. Figure 5A It can be seen that the electronic device and the network device perform downlink transmission in an aggregated manner through the first carrier and the second carrier, and perform conventional uplink transmission on the first carrier. The resources configured as SUL deactivation on the second carrier also perform uplink transmission in an aggregated manner with the first carrier. Figure 5B It can be seen that time domain 0, time domain 1 and time domain 2 on the first carrier and time domain 0, time domain 1 and time domain 2 on the second carrier are used for downlink transmission in a carrier aggregation manner, time domain 3 on the first carrier is used for downlink transmission, time domain 4 on the first carrier is used for uplink transmission, time domain 3 on the second carrier is SUL deactivated and is transmitted in an aggregated manner with the uplink of the first carrier, and time domain 4 on the second carrier is a flexible time domain resource.

[0135] If the electronic device does not support UL CA, the configuration information of the secondary cell received by the electronic device only includes the downlink configuration of the second carrier. Therefore, the electronic device deactivates the uplink of the second carrier according to the configuration information of the secondary cell, and the uplink of the second carrier is not transmitted. That is, the second carrier is converted from the SUL as the first carrier to the deactivated SUL, and is not transmitted through the uplink of the second carrier.

[0136] Schematic diagram of communication scenario between electronic devices and network devices Figure 5C As shown, the working status diagram is as follows Figure 5D As shown. Figure 5CIt can be seen that the electronic device and the network device perform downlink transmission in an aggregated manner through the first carrier and the second carrier, and perform conventional uplink transmission on the first carrier, and some time slots of the second carrier are deactivated SUL of the first carrier. Figure 5D It can be seen that time domain 0, time domain 1 and time domain 2 on the first carrier and time domain 0, time domain 1 and time domain 2 on the second carrier are used for downlink transmission in a carrier aggregation manner, time domain 3 on the first carrier is used for downlink transmission, time domain 3 on the second carrier is SUL deactivation, time domain 4 on the first carrier is uplink transmission, and time domain 4 on the second carrier is a flexible time domain resource. When SUL is deactivated, the electronic device does not send PRACH, SRS, PUCCH and PUSCH (UL-SCH) on SUL. When the uplink transmission of the second carrier is configured as SUL deactivation, the random access process being performed on SUL is terminated, but the transmission of NUL is not affected.

[0137] Step S504: the network device sends a third message to the electronic device.

[0138] Specifically, please refer to step S403 for detailed description.

[0139] Step S505: The electronic device receives the third message.

[0140] Specifically, please refer to step S405 for detailed description.

[0141] Step S506: the electronic device releases or deactivates the secondary cell according to the third message, and activates the uplink of the second carrier as a supplementary uplink of the first carrier.

[0142] Specifically, if the electronic device receives a third message sent by the network device including configuration information for releasing the secondary cell, the SCell is released according to the configuration information for releasing the secondary cell. For the relevant description of releasing the SCell, reference may be made to Section 5.3.10.3a of 3GPP TS36.331 V11.1.0 (2019-09); or if the electronic device receives a third message sent by the network device including configuration information for deactivating the secondary cell, the SCell is deactivated according to the configuration information for deactivating the secondary cell. Whether the SCell is deactivated or the SCell is released, it indicates that the first carrier and the second carrier of the electronic device are no longer aggregated. That is, when the electronic device does not perform downlink transmission with the first carrier in a carrier aggregation manner through the second carrier, the electronic device activates the uplink of the second carrier as a supplementary uplink of the first carrier. It should be noted that the electronic device activates the uplink of the second carrier as a supplementary uplink of the first carrier, that is, activates the configuration information about the SUL on the second carrier, and converts the second carrier from the SUL deactivated state to the SUL activated state.

[0143] At this time, the communication scenario diagram between the electronic device and the network device is as follows: Figure 2 As shown, the working status diagram is as follows Figure 3A It can be understood that the communication between the electronic device and the network device is as follows: Figure 5A or Figure 5C The method shown falls back to Figure 2 Correspondingly, the working state between the electronic device and the network device changes from Figure 5B or Figure 5D The status shown returns to Figure 3B Status shown.

[0144] Option 3

[0145] Combine the following Figure 6 Introducing Option 3, Figure 6 is a flow chart of a carrier configuration method provided in an embodiment of the present application, such as Figure 6 As shown, the method includes but is not limited to the following steps:

[0146] Step S601: The network device sends a first message to the electronic device.

[0147] Specifically, please refer to step 401 for detailed description.

[0148] Step S602: The electronic device receives a first message.

[0149] Specifically, please refer to step 402 for detailed description.

[0150] Step S603: The electronic device configures a serving cell corresponding to the second carrier according to the configuration information of the secondary cell.

[0151] Specifically, the configuration information of the SCell includes the downlink configuration of the second carrier, and the electronic device configures the downlink of the second carrier to be aggregated with the downlink of the first carrier according to the configuration information of the SCell.

[0152] In some embodiments, before the electronic device receives the first message sent by the network device, the network device may receive the electronic device capability information sent by the electronic device, and the network device may determine whether the electronic device supports uplink carrier aggregation (UL CA) according to the electronic device capability information. If the electronic device supports UL CA, the configuration information of the secondary cell received by the electronic device includes not only the downlink configuration of the second carrier, but also the uplink configuration of the second carrier. Therefore, the electronic device configures the uplink of the second carrier to aggregate with the uplink of the first carrier according to the configuration information of the secondary cell.

[0153] Schematic diagram of communication scenario between electronic devices and network devices Fig. 6A As shown, the working status diagram is as follows Figure 6B As shown. Fig. 6A It can be seen that the electronic device and the network device perform downlink transmission through the first carrier and the second carrier in an aggregated manner, and also perform uplink transmission through the first carrier and the second carrier in an aggregated manner. Figure 6B It can be seen that time domain 0, time domain 1 and time domain 2 on the first carrier and time domain 0, time domain 1 and time domain 2 on the second carrier are used for downlink transmission in a carrier aggregation manner, time domain 3 on the first carrier and time domain 3 on the second carrier are used for uplink transmission in a carrier aggregation manner, time domain 4 on the first carrier is used for uplink transmission, and time domain 4 on the second carrier is a flexible time domain resource.

[0154] Step S604: the network device sends a third message to the electronic device.

[0155] Specifically, please refer to step S403 for detailed description.

[0156] Step S605: The electronic device receives the third message.

[0157] Specifically, please refer to step 405 for detailed description.

[0158] Step S606: the electronic device releases the secondary cell or deactivates the secondary cell, and reconfigures the uplink of the second carrier to supplement the uplink of the first carrier.

[0159] Specifically, if the electronic device receives a third message sent by the network device including configuration information for releasing the secondary cell, the SCell is released according to the configuration information for releasing the secondary cell. For the relevant description of releasing the SCell, please refer to Section 5.3.10.3a of 3GPP TS36.331 V11.1.0 (2019-09); or if the electronic device receives a third message sent by the network device including configuration information for deactivating the secondary cell, the SCell is deactivated according to the configuration information for deactivating the secondary cell. Whether deactivating the SCell or releasing the SCell, it indicates that the first carrier and the second carrier of the electronic device are no longer aggregated. That is, when the electronic device does not perform downlink transmission with the first carrier through the second carrier in a carrier aggregation manner, the electronic device reconfigures the uplink of the second carrier to be a supplementary uplink of the first carrier.

[0160] It should be noted that the electronic device reconfigures the uplink of the second carrier to be a supplementary uplink of the first carrier, that is, reconfigures the uplink configuration of the carrier aggregation on the second carrier to be a SUL configuration. Figure 2 As shown, the working status diagram is as follows Figure 3B It is understood that the communication method between the electronic device and the network device is as follows: Fig. 6A Fallback to Figure 2Correspondingly, the working state between the electronic device and the network device changes from Figure 6B The status shown returns to Figure 3B Status shown.

[0161] Option 4

[0162] Combine the following Figure 7 Introducing Option 4. Figure 7 is a flow chart of a carrier configuration method provided in an embodiment of the present application, such as Figure 7 As shown, the method includes but is not limited to the following steps:

[0163] Step S701: The network device sends a first message to the electronic device.

[0164] Specifically, please refer to step 401 for detailed description.

[0165] Step S702: The electronic device receives a first message.

[0166] Specifically, please refer to step 402 for detailed description.

[0167] Step S703: The electronic device configures the downlink operation of the serving cell corresponding to the second carrier according to the configuration information of the secondary cell.

[0168] Specifically, the configuration information of the SCell includes a downlink configuration of the second carrier, and the downlink configuration of the second carrier is used to indicate configuration of aggregation of the downlink of the second carrier and the downlink of the first carrier.

[0169] In some embodiments, before the electronic device receives the first message sent by the network device, the network device may receive the electronic device capability information sent by the electronic device, and the network device may determine whether the electronic device supports uplink carrier aggregation (UL CA) based on the electronic device capability information. If the electronic device supports UL CA, the configuration information of the secondary cell received by the electronic device includes not only the downlink configuration of the second carrier, but also the uplink configuration of the second carrier. If the electronic device does not support UL CA, the configuration information of the secondary cell received by the electronic device only includes the downlink configuration of the second carrier. Regardless of whether the configuration information of the secondary cell received by the electronic device includes the downlink configuration of the second carrier, the electronic device configures the downlink operation of the serving cell corresponding to the second carrier as downlink aggregation with the first carrier according to the configuration information of the secondary cell.

[0170] Step S704: The network device sends a second message to the electronic device.

[0171] Specifically, the second message is used to indicate the configuration of the service cell corresponding to the second carrier. The configuration of the service cell corresponding to the second carrier may specifically include: the uplink of the second carrier remains as a supplementary uplink of the first carrier, or the uplink of the second carrier is deactivated, or the uplink of the second carrier is aggregated with the uplink of the first carrier.

[0172] The second message includes the first MAC CE signaling or the first DCI signaling. The first MAC CE signaling and the first DCI signaling both include a 2-bit uplink operation parameter; the specific value of the 2-bit uplink operation parameter is 00 or 01 or 10 or 11.

[0173] Step S705: The electronic device receives the second message.

[0174] Specifically, the electronic device receives a second message sent by the network device, where the second message includes a first MAC CE signaling or a first DCI signaling.

[0175] Step S706: The electronic device configures the uplink operation of the serving cell corresponding to the second carrier according to the second message.

[0176] Specifically, the second message received by the electronic device includes the first MAC CE signaling or the first DCI signaling, and the uplink operation of the serving cell corresponding to the second carrier can be configured according to the specific value of the parameter in the first MAC CE signaling or the first DCI signaling.

[0177] Optionally, the second message received by the electronic device includes a first MAC CE signaling, and the first MAC CE signaling includes a 2-bit uplink transmission media access control element (UL transmission MAC CE, UL i T), i is a positive integer, indicating the number of carriers. i The value of T is used to indicate the uplink operation of the serving cell corresponding to the second carrier. i T can take the value 00, 01, 10, 11.

[0201] Combine the following Figure 8 Introducing Option 5, Figure 8 is a flow chart of a carrier configuration method provided in an embodiment of the present application, such as Figure 8 As shown, the method includes but is not limited to the following steps:

[0202] Step S801: The network device sends a first message to the electronic device.

[0203] Specifically, please refer to step 401 for detailed description.

[0204] Step S802: The electronic device receives a first message.

[0205] Specifically, please refer to step S402 for detailed description.

[0206] Step S803: The electronic device configures the downlink operation of the serving cell corresponding to the second carrier according to the configuration information of the secondary cell.

[0216] Step S808: The electronic device receives the third message.

[0217] Specifically, please refer to step S708 for detailed description.

[0218] Step S809: the electronic device releases the secondary cell or deactivates the secondary cell according to the third message.

[0219] Specifically, if the electronic device receives a third message sent by the network device including configuration information for releasing the secondary cell, the SCell is released according to the configuration information for releasing the secondary cell. For the relevant description of releasing the SCell, please refer to Section 5.3.10.3a of 3GPP TS36.331V11.1.0 (2019-09); or if the electronic device receives a third message sent by the network device including configuration information for deactivating the secondary cell, the SCell is deactivated according to the configuration information for deactivating the secondary cell. Whether deactivating the SCell or releasing the SCell, it indicates that the first carrier and the second carrier of the electronic device are no longer downlink aggregated. That is, the electronic device does not perform downlink transmission through the second carrier and the first carrier in a carrier aggregation manner.

[0220] Step S810: The electronic device receives a fourth message, and configures an uplink of a second carrier according to the fourth message.

[0221] Specifically, the fourth message received by the electronic device includes the second MAC CE signaling or the second DCI signaling, and the uplink operation of the second carrier is configured according to the specific value of the parameter included in the second MAC CE signaling or the second DCI signaling.

[0222] Optionally, the fourth message received by the electronic device includes a second MAC CE signaling, in which a 2-bit UL transmission MAC CE is included, and i is a positive integer, indicating the number of carriers. The value of UL transmission MACCE is used to indicate the uplink operation of the service cell corresponding to the second carrier. Among them, the 2-bit UL transmission MAC CE can take values ​​of 00, 01, 10, and 11. For example, the UL transmission MAC CE value of 00 can be used to indicate that the uplink of the second carrier is configured not to be transmitted; the UL transmission MAC CE value of 01 can be used to indicate that the uplink of the second carrier is retained as a supplementary uplink of the first carrier; the UL transmission MAC CE value of 10 can be used to indicate that the uplink of the second carrier is activated as a supplementary uplink of the first carrier; the UL transmission MAC CE value of 11 can be used to indicate that the uplink of the second carrier is reconfigured as a supplementary uplink of the first carrier. It should be noted that the uplink operation corresponding to the value of UL transmission MAC CE is an example of an embodiment of the present application, and may not be limited to those listed in the embodiments of the present application.

[0223] For example, before the electronic device receives the third message to release or deactivate the secondary cell, if the uplink of the second carrier is a supplementary uplink of the first carrier, the value of the ULtransmission MAC CE in the second MAC CE signaling contained in the fourth message received by the electronic device can be 01, and the electronic device will retain the uplink of the second carrier as a supplementary uplink of the first carrier, that is, retain the configuration information about the SUL on the second carrier. At this time, the communication scenario diagram between the electronic device and the network device is as follows Figure 2 As shown, the working status diagram is as follows Figure 3A It can be understood that the communication between the electronic device and the network device is as follows: Figure 4A The method shown falls back to Figure 2 Correspondingly, the working state between the electronic device and the network device changes from Figure 4B Falling back to Figure 3A shown.

[0224] If the uplink of the second carrier is to deactivate the SUL and aggregate the uplink with the first carrier, the value of the UL transmission MAC CE in the second MAC CE signaling contained in the second message received by the electronic device can be 10, and the electronic device activates the uplink of the second carrier as a supplementary uplink of the first carrier. That is, the configuration information about SUL on the second carrier is activated, and the second carrier is converted from deactivating the SUL and transmitting by aggregating the uplink with the first carrier to the SUL of the first carrier. At this time, the communication scenario diagram between the electronic device and the network device is as follows: Figure 2 As shown, the working status diagram is as follows Figure 3A It can be understood that the communication between the electronic device and the network device is as follows: Figure 5A The method shown falls back to Figure 2 Correspondingly, the working state between the electronic device and the network device changes from Figure 5B Falling back to Figure 3A shown.

[0225] If the uplink of the second carrier is aggregated with the uplink of the first carrier, the value of the UL transmission MAC CE in the second MAC CE signaling included in the second message received by the electronic device can be 11, and the electronic device reconfigures the uplink of the second carrier as a supplementary uplink of the first carrier, that is, reconfigures the uplink configuration of the carrier aggregation on the second carrier to the SUL configuration. At this time, the communication scenario diagram between the electronic device and the network device is as follows Figure 2 As shown, the working status diagram is as follows Figure 3A It can be understood that the communication between the electronic device and the network device is as follows: Fig. 6A The method shown falls back to Figure 2 Correspondingly, the working state between the electronic device and the network device changes from Figure 6B Falling back to Figure 3A shown.

[0226] Optionally, the fourth message received by the electronic device includes a second DCI signaling, and a 2-bit UL transmission indicator is included in DCI format 0_0 and 0_1, and the UL transmission indicator is used to indicate the uplink transmission mode of the service cell corresponding to the second carrier. Among them, the value of the 2-bit UL transmission indicator is 00, 01, 10, 11. For example, the UL transmission indicator value of 00 in DCI format 0_0 and 0_1 can be used to indicate that the uplink of the second carrier is configured not to be transmitted; the UL transmission indicator value of 01 in DCI format 0_0 and 0_1 can be used to indicate that resources for SUL transmission are reserved; the UL transmission indicator value of 10 in DCI format 0_0 and 0_1 can be used to indicate that the uplink of the second carrier is activated as a supplementary uplink of the first carrier; the UL transmission indicator value of 11 in DCI format 0_0 and 0_1 can be used to indicate that the uplink of the second carrier is reconfigured as a supplementary uplink of the first carrier. It should be noted that the uplink operation corresponding to the value of the UL transmission indicator in DCI format 0_0 and 0_1 is an example of the embodiment of the present application and may not be limited to that listed in the embodiment of the present application.

[0227] For example, before the electronic device receives the third message to release or deactivate the secondary cell, if the uplink of the second carrier is a supplementary uplink of the first carrier, the specific description of the second DCI signaling contained in the fourth message received by the electronic device can refer to the specific description of the second MAC CE signaling contained in the fourth message, which will not be repeated here.

[0228] If the uplink behavior of the second carrier is to deactivate SUL and perform uplink aggregation with the first carrier, the specific description of the second DCI signaling contained in the second message received by the electronic device can refer to the specific description of the second MAC CE signaling contained in the fourth message, which will not be repeated here.

[0229] If the uplink of the second carrier is aggregated with the uplink of the first carrier, the specific description of the second DCI signaling included in the second message received by the electronic device can refer to the specific description of the second MAC CE signaling included in the fourth message, which is not repeated here.

[0230] Optionally, the fourth message received by the electronic device includes a second MAC CE signaling, and the second MAC CE signaling includes a 1-bit UL transmission MAC CE (UL i C), i is a positive integer, indicating the number of carriers. The value of UL transmission MAC CE is used to indicate the uplink operation of the serving cell corresponding to the second carrier. The 1-bit UL transmission MAC CE can be 0 or 1.

[0231] The value of the 1-bit UL transmission MAC CE may include the following cases:

[0232] Case 1, UL i The value of C is 0, which can be used to indicate that the uplink of the second carrier is reserved as a supplementary uplink of the first carrier. i The value of C is 1, which can be used to indicate that the uplink of the second carrier is activated as a supplementary uplink of the first carrier;

[0233] Case 2, UL i The value of C is 0, which can be used to indicate that the uplink of the second carrier is reserved as a supplementary uplink of the first carrier. i The value of C is 1, which may be used to indicate that the uplink of the second carrier is reconfigured as a supplementary uplink of the first carrier;

[0234] Case 3, UL i The value of C is 0, which can be used to indicate that the uplink of the second carrier is reconfigured to be a supplementary uplink of the first carrier. i The value of C being 1 may be used to indicate that the uplink of the second carrier is activated as a supplementary uplink of the first carrier.

[0235] It should be noted that UL i The uplink operation corresponding to the value of C is an example of the embodiment of the present application and may not be limited to the examples listed in the embodiment of the present application. i The value of C is 1, which can be used to indicate that the uplink of the second carrier is reserved as a supplementary uplink of the first carrier. i The value of C being 0 may be used to indicate that the uplink of the second carrier is activated as a supplementary uplink of the first carrier.

[0236] For example, before the electronic device receives the second message to release or deactivate the secondary cell, if the uplink of the second carrier is a supplementary uplink of the first carrier, the value of the ULtransmission MAC CE in the second MAC CE signaling included in the fourth message received by the electronic device may be 0 in case 1, or 0 in case 2. The electronic device will retain the uplink of the second carrier as a supplementary uplink of the first carrier, that is, including the configuration information about the SUL on the second carrier.

[0237] If the uplink of the second carrier is to deactivate the SUL and aggregate the uplink with the first carrier, the value of the UL transmission MAC CE in the second MAC CE signaling contained in the fourth message received by the electronic device can be 1 in case one, or 1 in case three. The electronic device activates the uplink of the second carrier as a supplementary uplink of the first carrier. That is, it activates the configuration information about the SUL on the second carrier, and converts the second carrier from deactivating the SUL and transmitting by aggregating the uplink with the first carrier to the SUL of the first carrier. It should be noted that in this case, the UL transmission MAC CE can be called SUL active MAC CE (Sa i ), i represents the number of SUL. Fig. 8A The following is a schematic diagram of SUL active MAC CE. Fig. 8A It can be seen that Sa i Indicates the activation status of SUL, Sa i When the value is 1, SUL is activated. 2 When the value of is 1, it indicates that the configuration information about SUL on the second carrier is activated. Fig. 8A The R in represents a flexible configuration area.

[0238] If the uplink of the second carrier is aggregated with the uplink of the first carrier, the value of the UL transmission MAC CE in the second MAC CE signaling included in the fourth message received by the electronic device may be 1 in case 2, or 0 in case 3. The electronic device reconfigures the uplink of the second carrier as a supplementary uplink of the first carrier, that is, reconfigures the uplink configuration on the second carrier regarding carrier aggregation as a SUL configuration.

[0239] Optionally, the fourth message received by the electronic device includes the second DCI signaling, and DCI formats 0_0 and 0_1 include a 1-bit UL transmission indicator, where the UL transmission indicator is used to indicate the uplink transmission mode of the serving cell corresponding to the second carrier.

[0240] The situations included in the value of 1-bit UL transmission indicator can refer to the situations included in the value of 1-bit UL transmission MAC CE, which will not be repeated here.

[0241] For example, before the electronic device receives the second message to release or deactivate the secondary cell, if the uplink of the second carrier is a supplementary uplink of the first carrier, the specific description of the fourth message received by the electronic device containing the second DCI signaling can refer to the specific description of the fourth message containing the second MAC CE signaling, which will not be repeated here.

[0242] If the uplink of the second carrier is to deactivate the SUL and perform uplink aggregation with the first carrier, the fourth message received by the electronic device includes the second DCI signaling, and the DCI format 0_0 and 0_1 include a 1-bit UL transmission indicator, and the value of the 1-bit UL transmission indicator can be 1 in case one, or 1 in case three. The electronic device will activate the uplink of the second carrier as a supplementary uplink of the first carrier. That is, activate the configuration information about the SUL on the second carrier, and convert the second carrier from deactivating the SUL and transmitting by aggregating with the uplink of the first carrier to the SUL of the first carrier. It should be noted that in this case, the UL transmission indicator can be called the SUL active indicator.

[0243] If the uplink of the second carrier is aggregated with the uplink of the first carrier, the specific description of the fourth message received by the electronic device including the second DCI signaling can refer to the specific description of the fourth message including the second MAC CE signaling, which is not repeated here.
