[0015] The following describes the embodiments of the present application in conjunction with the accompanying drawings. The following describes the present application in conjunction with the accompanying drawings. The examples are only used to explain the present application and are not used to limit the scope of the present application.

[0016] In the carrier aggregation scenario, there are three system message transmission schemes:

[0017] In Method 1, each downlink carrier in multiple serving cells (carriers) serves as an accessible carrier. Each downlink carrier has a synchronization signal, a physical broadcast channel, and a physical downlink shared channel for transmitting system information (SI). Each downlink carrier corresponds to an uplink carrier and can be considered an independent serving cell. Terminals can access and reside on each uplink and downlink carrier for data transmission. This method has the disadvantage that the terminal needs to obtain the SI of each serving cell separately, which increases terminal power consumption. In addition, the physical broadcast channel and SI transmission need to be sent periodically, which also increases network power consumption. This is especially harmful in scenarios where there is no downlink service, which is not conducive to network energy conservation.

[0018] Method 2: Based on Method 1, the SI of each serving cell can be transmitted across carriers, using other carriers (such as the primary cell (Pcell)). In this way, some downlink carriers can transmit the SI of other carriers, thereby reducing the power consumption of the downlink carrier. In addition, the terminal can also obtain the SI of multiple serving cells through one serving cell, which can also reduce the SI acquisition process after the terminal carrier switches, reduce the switching delay, and achieve terminal energy saving. However, the disadvantage of this method is that the SI transmission overhead may increase, the terminal is limited in obtaining SI, and it needs to obtain it on a specific carrier, which also increases the complexity of terminal SI acquisition.

[0019] In method 3, multiple serving cells share a physical broadcast channel (PBCH) and SI, which are transmitted on a single serving cell (Pcell). The SI includes the access resources and corresponding downlink detection configurations for the multiple serving cells, as well as the paging opportunities and detection configurations for the multiple serving cells. This method reduces signaling overhead and achieves both network and terminal energy savings. However, this method has the drawback of limiting SI acquisition for terminals, requiring them to acquire SI on specific carriers, which increases the complexity of SI acquisition for terminals.

[0020] In scenarios 2 and 3, the UE has three options for using secondary carriers. One is carrier aggregation, which involves activating a secondary carrier and combining the primary and secondary carriers. This allows the UE to continuously receive system messages. However, this approach increases congestion on the primary carrier, requiring the terminal to have multi-carrier capabilities and resulting in higher terminal costs. Another option is for the UE to access the network after receiving system messages on the Pcell (Pcell) and, based on predefined rules, select a carrier from the list of access carriers broadcast in the system message. Once connected, data is transmitted on this carrier or a network-configured carrier. If the UE is resident on a secondary carrier (cell) for data transmission and the system message changes, the UE must switch back to the Pcell to receive the changed system message. Another option is to transmit the changed system message separately on the secondary carrier. This reduces the complexity of SI reception for the terminal, avoiding the need for SI reception on the primary carrier. Efficiently obtaining changed system messages based on system message change indication information is a pressing issue. Furthermore, if the UE is resident on the secondary carrier even in idle state, performing co-frequency and neighboring cell measurements to minimize terminal power consumption is also a pressing issue.

[0021] In one embodiment, FIG1 is a flowchart of a carrier configuration method provided by an embodiment of the present application. This embodiment can be performed by a first communications device. For example, the first communications device can be a terminal, such as a user equipment (UE). As shown in FIG1 , this embodiment includes steps S110 to S120.

[0022] S110: Receive carrier configuration information sent by a second communication device.

[0023] S120: Perform carrier configuration according to the carrier configuration information.

[0024] The first communication device receives the carrier configuration information sent by the second communication device on the secondary carrier currently resident, and issues a switching instruction to the primary carrier, configures the downlink carrier, or measures the secondary carrier according to the carrier configuration information.

[0025] In one embodiment, the carrier configuration information includes one of the following: first main carrier indication information; downlink carrier configuration information; auxiliary carrier measurement information; wherein the first main carrier indication information includes at least one of the following: main carrier switching indication information; main carrier activation indication information; system message change indication information; system message; changed system message; auxiliary carrier scheduling main carrier indication information.

[0026] The secondary carrier measurement information includes at least one of the following: secondary carrier co-frequency measurement threshold; secondary carrier adjacent frequency measurement threshold and neighboring cell list; primary carrier measurement threshold; adjacent frequency measurement interval; primary carrier measurement interval. In one example, the primary carrier switching indication information is used to indicate that the first communication device switches from the secondary carrier to the primary carrier and performs data transmission on the primary carrier, or performs measurement on the primary carrier, or detects scheduling information corresponding to a system message on the primary carrier, or receives a changed system message on the primary carrier, or detects corresponding scheduling information on the primary carrier. In one example, the primary carrier activation indication information is used to indicate that the first communication device activates the primary carrier to implement a mode of multiple carrier reception of the primary carrier and the secondary carrier. In one example, the downlink carrier configuration information is used to configure the uplink carrier corresponding to the first communication device as a downlink carrier for synchronization or scheduling. In one example, the first communication device can perform co-frequency measurement, adjacent frequency measurement, primary carrier measurement, or carrier switching on the serving cell on the secondary carrier based on the secondary carrier measurement information.

[0027] In one embodiment, when the first primary carrier indication information includes primary carrier activation indication information or system message change indication information, performing carrier configuration according to the carrier configuration information includes: activating the primary carrier according to the primary carrier activation indication information or the system message change indication information. When the first communications device detects the primary carrier activation indication information or the system message change indication information on the secondary carrier on which it resides, the first communications device activates the primary carrier.

[0028] In one embodiment, after the primary carrier is activated, the carrier configuration method applied to the first communication device further includes: enabling reception modes of the secondary carrier and the primary carrier; performing data transmission with the second communication device on the primary carrier, or performing measurements on the primary carrier, or detecting scheduling information corresponding to a system message on the primary carrier, or receiving a changed system message on the primary carrier, or detecting corresponding scheduling information on the primary carrier.

When the first communications device detects the primary carrier switching indication information or the system message change indication information on the secondary carrier where it resides, the first communications device switches from the secondary carrier where it resides to the primary carrier.

[0030] In one embodiment, a carrier configuration method applied to a first communication device further includes: sending second primary carrier indication information to a second communication device after receiving a system message about a change on the primary carrier or when a first preset condition is met. In one example, the second primary carrier indication information indicates deactivation of the primary carrier. After the first communication device receives the system message about the change on the primary carrier, it may proactively send the second primary carrier indication information to the second communication device.

[0031] In one embodiment, the carrier configuration method applied to the first communication device further includes: receiving third primary carrier indication information sent by the second communication device; wherein the third primary carrier indication information includes one of the following: deactivation of the primary carrier indication information; secondary carrier switching indication information; deactivating the primary carrier according to the third primary carrier indication information, and switching to the secondary carrier for data transmission, or, when the secondary carrier and primary carrier receiving mode are enabled, deactivating the primary carrier according to the third primary carrier indication information, and residing on the secondary carrier for data transmission. After the second communication device receives the second primary carrier indication information sent by the first communication device, the second communication device sends the third primary carrier indication information to the first communication device, so that the first communication device deactivates the primary carrier and switches to the secondary carrier to continue data transmission; if the first communication device enables the secondary carrier and primary carrier receiving mode, the first communication device deactivates the primary carrier according to the third primary carrier indication information, and residing on the secondary carrier for data transmission.

[0032] In one embodiment, the first preset condition includes one of the following: a reference signal received power (RSRP) value less than an RSRP threshold; a reference signal received quality (RSRQ) value less than an RSRQ threshold; a reference signal signal to noise ratio (SNR) value less than an SNR threshold; an actual channel state information (CSI) measurement value less than a CSI measurement threshold; a radio link failure; beam switching; or a service channel retransmission count reaching a preset retransmission count threshold. The threshold corresponding to the first preset condition may be configured by the second communication device.

[0033] In one embodiment, the carrier configuration method applied to the first communication device further includes: deactivating the primary carrier through implicit signaling. In one example, implicit signaling can be understood as actively deactivating the primary carrier without sending relevant indication information for deactivating the primary carrier.

[0034] In one embodiment, deactivating the primary carrier by implicit signaling includes one of the following: after sending the second primary carrier indication information to the second communication device, the duration of no data transmission of the first communication device on the primary carrier reaches a first preset duration, and the primary carrier is deactivated; after sending the second primary carrier indication information to the second communication device, within the first preset duration, the first communication device does not receive the specific response information sent by the second communication device, and the primary carrier is deactivated; wherein, the specific response information includes one of the following: primary carrier maintenance information, primary carrier RRC configuration information, primary carrier RRC reconfiguration information, auxiliary carrier deactivation information, primary carrier measurement information; the specific response information may also be other information, and its function is to allow the first communication device to station Stay on the main carrier for data transmission; after the main carrier is activated, the duration of no data transmission by the first communication device on the main carrier reaches a second preset duration, and the main carrier is deactivated; after the main carrier is activated, within the second preset duration, the first communication device does not receive specific response information sent by the second communication device, and the main carrier is deactivated; wherein the specific response information includes one of the following: main carrier retention information, main carrier RRC configuration information, main carrier RRC reconfiguration information, auxiliary carrier deactivation information, and main carrier measurement information; the specific response information may also be other information, whose function is to allow the first communication device to reside on the main carrier for data transmission; the residence time on the main carrier reaches a third preset time, and the main carrier is deactivated.

[0035] In one example, after a first communications device sends a primary carrier deactivation request and a system message acquisition completion message to a second communications device, if no downlink data transmission, uplink data scheduling, or confirmation information related to the first communications device is received on the primary carrier, and no data transmission by the first communications device lasts for a first preset duration, the first communications device may proactively deactivate the primary carrier. In another example, after the first communications device activates the primary carrier, if no data transmission by the first communications device lasts for a second preset duration on the carrier, the first communications device may assume that the second communications device has permitted the first communications device to deactivate the primary carrier. In another example, after the first communications device activates and switches to the primary carrier, if the duration of the first communications device's stay on the primary carrier lasts for a third preset duration, the first communications device may proactively deactivate the primary carrier. In another example, after sending second primary carrier indication information to the second communications device, if the first communications device does not receive specific response information from the second communications device within a first preset duration, such as primary carrier RRC reconfiguration information, secondary carrier deactivation information, or primary carrier retention information, the first communications device may proactively deactivate the primary carrier. In one example, after activating the primary carrier, if the first communications device does not receive specific response information sent by the second communications device within a second preset duration, such as primary carrier RRC reconfiguration information, secondary carrier deactivation information, or primary carrier retention information, the first communications device may proactively deactivate the primary carrier. In one example, the first preset duration, the second preset duration, and the third preset duration may be configured by the second communications device, and the first preset duration, the second preset duration, and the third preset duration may be different.

[0042] The DCI is transmitted on the secondary carrier, and the PDSCH scheduled by the DCI is transmitted on the primary carrier.

After the first communication device receives the PDSCH on the primary carrier, it switches back to the secondary carrier to continue data transmission; or, the DCI is transmitted on the secondary carrier, and the PDSCH scheduled by the DCI is transmitted on the primary carrier. Before receiving the PDSCH, the first communication device activates the primary carrier and starts receiving the secondary carrier and the primary carrier at the same time. After the UE receives the PDSCH on the primary carrier, it deactivates the primary carrier and stays on the secondary carrier to continue data transmission; the UE determines whether the PDSCH scheduled by the DCI carries SI based on the specific RNTI (such as SI-RNTI) scrambled by the CRC of the DCI, and the UE Determine whether the PDSCH scheduled by the DCI is on the auxiliary carrier or the main carrier according to the RRC configuration information, or, the UE determines whether the PDSCH scheduled by the DCI is on the auxiliary carrier or the main carrier according to the signaling in the DCI (such as: carrier indication), or, the UE determines whether the PDSCH scheduled by the DCI is on the auxiliary carrier or the main carrier according to the specific RNTI scrambled by the CRC of the DCI, such as: the RNTI corresponding to the auxiliary carrier is S-SI-RNTI, and the RNTI corresponding to the main carrier is P-SI-RNTI.

[0050] In one example, configuring a synchronous downlink carrier corresponding to a downlink carrier for a downlink carrier of a first communication device can be understood as, if there is no SSB or no downlink synchronization signal on the downlink carrier, downlink synchronization can be performed with reference to the SSB or other downlink reference signal of another downlink carrier. In one example, a downlink carrier set can be understood as, multiple downlink carriers can be virtualized into one carrier for data scheduling and transmission, and the second communication device can configure a DCI Format corresponding to a search space to be a DCI format for virtualizing multiple downlink carriers into one virtual carrier, or a DCI format for one downlink carrier.

In one example, a downlink carrier or a subband position on the full-duplex carrier or a subband index on the full-duplex carrier or a subband identifier on the full-duplex carrier for transmitting full-duplex carrier scheduling information is configured for the full-duplex carrier of the first communication device. The uplink scheduling information and / or downlink scheduling information corresponding to the full-duplex carrier can be scheduled by the same downlink carrier, or the downlink carrier corresponding to the uplink scheduling information and the downlink scheduling information of the full-duplex carrier are configured respectively for corresponding scheduling information transmission. If the downlink carrier for transmitting the scheduling information is a full-duplex carrier and the full-duplex carrier has multiple downlink subbands, it is necessary to indicate the corresponding subband position or subband index or subband identifier for transmitting the scheduling information. In one example, if a full-duplex carrier has multiple downlink subbands or multiple uplink subbands, the multiple downlink subbands or multiple uplink subbands can be configured for each subband to transmit the corresponding downlink carrier or subband on the full-duplex carrier whose scheduling information is transmitted, or the multiple downlink subbands or multiple uplink subbands can be configured for the corresponding downlink carrier or subband on the full-duplex carrier to transmit the scheduling information according to the downlink subband or uplink subband as a whole, that is, all uplink subbands of the full-duplex subband correspond to the same downlink carrier or subband on the full-duplex carrier, all downlink subbands of the full-duplex subband correspond to the same downlink carrier or subband on the full-duplex carrier, or all subbands on the full-duplex carrier correspond to the same downlink carrier or subband on the full-duplex carrier.

[0065] It should be noted that for the explanation of parameters such as the carrier configuration information, first main carrier indication information, downlink carrier configuration information, auxiliary carrier measurement information, second main carrier indication information, and third main carrier indication information in the carrier configuration method applied to the second communication device, please refer to the description of the corresponding parameters in the above-mentioned carrier configuration method applied to the first communication device, and will not be repeated here.

[0066] In the following embodiments, the carrier configuration process is described by taking the first communication device as a UE and the second communication device as a network side (eg, a base station) as an example.

[0067] In the first embodiment, the primary carrier configuration process is described by taking the case where the UE activates the primary carrier on the secondary carrier, that is, the UE can receive data on multiple carriers as an example.

[0068] After the UE obtains the system message in the Pcell, it selects a carrier from the access carrier list broadcast in the system message according to predefined rules to access the network. After access, data is transmitted on this carrier or a carrier configured by the network, and the UE resides on the secondary carrier (cell) for data transmission.

[0069] When the network side prepares to change the system message, the network side transmits the system message change indication information on the secondary carrier, or when the network side requires the UE to receive data on the primary carrier, the network side sends the primary carrier switching indication information or the primary carrier activation indication information, and the network side transmits the changed system message and or UE data on the primary carrier.

[0070] After the network side receives the primary carrier deactivation request or system message acquisition completion message sent by the UE, the network side sends primary carrier deactivation indication information to the UE.

[0071] After the UE detects the system message change indication information or the main carrier activation indication information on the secondary carrier (the base station requires the UE to receive data on the primary carrier), the UE activates the primary carrier, turns on the secondary carrier and the main carrier reception mode, receives the changed system message on the primary carrier, and after completing the reception of the changed system message, actively reports the system message acquisition completion message to the network side, or the UE requests the network side to deactivate the primary carrier, and the network side sends the main carrier deactivation indication information to the UE. After obtaining the deactivation indication information, the UE deactivates the primary carrier and continues data transmission or resides on the secondary carrier.

[0072] The system message change indication information may be transmitted via the PDCCH. The system message change indication information is included in a specific DCI Format and indicated via downlink control information.

[0073] The system message change indication information may also be transmitted via MAC CE and identified by a specific MAC header.

[0074] The system message change indication information may also be transmitted via an RRC message.

[0075] The primary carrier deactivation request or system message acquisition completion message sent by the UE may be transmitted through a MAC CE and identified by a specific MAC header; may also be transmitted through an RRC message or through a specific UCI.

[0076] After the UE sends a deactivation primary carrier request or a system message acquisition completion message to the network side, if the duration for which no downlink data transmission or uplink data scheduling or confirmation information is received on the primary carrier reaches a first preset duration, the UE may also actively deactivate the primary carrier; correspondingly, after the network side receives the deactivation primary carrier request or the system message acquisition completion message sent by the UE, if the network side hopes that the UE will deactivate the primary carrier, within the first preset duration, no downlink data transmission or uplink data scheduling is sent on the primary carrier or confirmation information is sent to the UE, the network side assumes that the UE has deactivated the primary carrier; if the network side does not want the UE to deactivate the primary carrier, it sends downlink data or performs uplink data scheduling on the primary carrier or does not send a confirmation message to the UE.

[0077] After the UE activates the primary carrier, if the duration of not receiving downlink data transmission on the primary carrier reaches a second preset duration, the UE may assume that the network has allowed the UE to deactivate the primary carrier. After the network activates the UE's primary carrier, if the network wishes the UE to deactivate the primary carrier, no downlink data transmission or uplink data scheduling will be sent on the primary carrier within the second preset duration. After this time, the network assumes that the UE has deactivated the primary carrier. If the network does not want the UE to deactivate the primary carrier, it will send downlink data or perform uplink data scheduling on the primary carrier. If both the first preset duration and the second preset duration are configured by the network, after the UE activates the primary carrier, if the activation duration / residence duration on the primary carrier reaches a third preset duration configured by the network, the UE may automatically deactivate the primary carrier. After the network activates the UE's primary carrier, after the third preset duration configured by the network expires, the network assumes that the UE has deactivated the primary carrier. If the network does not want the UE to deactivate the primary carrier, it will send explicit signaling on the primary carrier to instruct the UE to maintain the primary carrier.

[0078] Optionally, after activating the primary carrier, the UE performs system message reacquisition and / or primary carrier measurement.

[0079] Optionally, after the UE deactivates the primary carrier, the UE may not perform monitoring or primary carrier measurement on the primary carrier.

[0080] There is a predefined or configured time interval between the UE obtaining the system message change indication information or the primary carrier activation indication and activating the primary carrier.

[0081] In the second embodiment, the primary carrier configuration process is described by taking the example of UE switching from the secondary carrier to the primary carrier, that is, the UE can perform uplink and downlink data transmission on the primary carrier.

[0082] When the UE resides on the secondary carrier (secondary cell) and does not activate the primary carrier (primary cell), that is, cannot receive the secondary carrier (secondary cell) and the primary carrier (primary cell) at the same time, the UE performs uplink and downlink data transmission on the secondary carrier.

[0083] When the network side is preparing to change the system message, the network side transmits the system message change indication information on the secondary carrier, or when the network side requires the UE to receive data on the primary carrier, the network side sends the primary carrier switching indication information, and the network transmits the changed system message on the primary carrier. When the network side receives the carrier switching request or system message acquisition completion message sent by the UE, the network side sends the secondary carrier switching indication information to the UE, and the UE switches to the target carrier.

[0084] The UE detects the system message change indication information (or other preset conditions) on the secondary carrier, or the network side sends the main carrier activation indication information, the UE performs carrier switching, and switches from the secondary carrier to the main carrier, receives the changed system message and or UE data, the UE receives the changed system message on the main carrier, and after completing the reception of the changed system message, actively reports the system message acquisition completion message to the network side, or the UE sends a deactivation main carrier request or a carrier switching request to the network side based on the measurement value (for example, the RSRP value is less than the RSRP threshold, or the CSI measurement value is less than the CSI measurement threshold, etc.) or other preset conditions (such as: radio link failure, beam switching, number of service channel retransmissions, etc.), the network side sends a carrier switching indication information to the UE, and after obtaining the carrier switching indication information, the UE deactivates the main carrier and switches to the target carrier; the system message change indication information or the carrier switching indication information can be transmitted through the PDCCH, and the system message change indication information or the carrier switching indication information is included in a specific DCI Format and indicated by the downlink control information; the system message change indication information or the carrier switching indication information can also be transmitted through the MAC CE transmission is identified by a specific MAC header; system message change indication information or carrier switching indication information can also be transmitted through RRC messages.

[0085] The primary carrier deactivation request or system message acquisition completion message or carrier switching request sent by the UE may be transmitted through a MAC CE and identified by a specific MAC header; may also be transmitted through an RRC message or through a specific UCI.

[0086] In another optional manner, after the UE sends a request to deactivate the primary carrier, a system message acquisition completion message, or a carrier switching request to the network side, if the duration for which no downlink data transmission, uplink data scheduling, or confirmation information is received on the primary carrier reaches a first preset duration, the UE may actively deactivate the primary carrier and switch back to the original secondary carrier; correspondingly, after the network side receives the request to deactivate the primary carrier, the system message acquisition completion message, or the secondary carrier switching information sent by the UE, if the network side wishes the UE to deactivate the primary carrier, within the first preset duration, no downlink data transmission, uplink data scheduling, or confirmation information is sent to the UE on the primary carrier, the network side assumes that the UE has deactivated the primary carrier and switches back to the secondary carrier; if the network side does not want the UE to deactivate the primary carrier, it sends downlink data or performs uplink data scheduling on the primary carrier or does not send a confirmation message to the UE.

[0087] Another way to automatically deactivate the primary carrier is that the network side configures the UE's residence time on the primary carrier. When the residence time reaches a third preset time, the UE autonomously switches to the target secondary carrier. During the period when the UE resides on the primary carrier, if the network side does not want the UE to deactivate the primary carrier, it sends downlink data, performs uplink data scheduling, or displays signaling on the primary carrier to allow the UE to reside on the primary carrier.

[0088] Optionally, after activating the primary carrier, the UE performs system message reacquisition and / or primary carrier measurement.

[0089] Optionally, after the UE deactivates the primary carrier, the UE may not perform monitoring or primary carrier measurement on the primary carrier.

[0090] There is a predefined or configured time interval between the UE obtaining the system message change indication information or the primary carrier activation indication and activating the primary carrier.

[0091] In the third embodiment, the primary carrier configuration process is described by taking the network side's independent transmission or repeated transmission on the secondary carrier as an example.

[0092] When the UE resides on the secondary carrier (secondary cell) and does not activate the primary carrier (primary cell), that is, cannot receive the secondary carrier (secondary cell) and the primary carrier (primary cell) at the same time, the UE performs uplink and downlink data transmission on the secondary carrier.

[0093] When the network side prepares a system message change, it transmits the changed system message on the secondary carrier. The changed system message is carried by the PDSCH scheduled by DCI. The DCI is scrambled by a dedicated RNTI (predefined or network-configured). The changed system message includes: the changed system message carried by one or more dedicated SIBs, or the changed system message carried by the MAC CE. All UEs residing on the secondary carrier can receive the changed system message. To ensure that all UEs on the secondary carrier can receive the changed system message, the network side can repeatedly transmit the changed system message by scheduling multiple transmissions of the first dedicated DCI Format. The advantage of this method is that it prevents UEs from switching to the primary carrier to receive the changed system message. The disadvantage is that the repeated transmission of the changed system message increases network resource overhead.

[0094] Another way is that the network side transmits the changed system information through the UE-specific PDSCH and carries the changed system information through the RRC message. The advantage of this method is that it can be jointly transmitted with the UE data, and the ACK / NACK feedback from the UE can be used to determine whether the UE has received it correctly, which has higher reliability. The disadvantage is that it is sent once for each UE, and the resource overhead is greater.

[0095] In the fourth embodiment, the process of the UE camping on the secondary carrier and performing intra-frequency, adjacent-frequency, and primary carrier measurements and carrier switching is described.

[0096] When the network side configures the secondary carrier list on which the UE resides, the network side configures the corresponding secondary carrier adjacent frequency measurement threshold, and / or, the secondary carrier co-frequency measurement threshold, and / or, the main carrier measurement threshold, and / or, the neighboring area list corresponding to the secondary carrier for one or more secondary carriers in the list; when the UE resides on the secondary carrier (secondary cell) and the main carrier (primary cell) is not activated, that is, it cannot receive the secondary carrier (secondary cell) and the main carrier (primary cell) at the same time, the UE performs uplink and downlink data transmission on the secondary carrier.

[0097] The UE measures the serving cell based on the reference signal of the secondary carrier. When the measurement value meets the co-frequency measurement trigger condition (such as: the measurement value is lower than the secondary carrier co-frequency measurement threshold configured by the network), the UE performs co-frequency measurement on the secondary carrier; when the measurement value meets the adjacent frequency measurement trigger condition (such as: the measurement value is lower than the secondary carrier adjacent frequency measurement threshold configured by the network), in the neighboring area measurement interval, the UE performs adjacent frequency measurement on the secondary carrier according to the neighboring area list corresponding to the secondary carrier configured by the network; when the measurement value meets the carrier switching trigger condition (such as: the measurement value is lower than the main carrier measurement threshold configured by the network), the UE switches from the secondary carrier to the main carrier in the main carrier measurement interval and measures the main carrier.

[0098] In the fifth embodiment, in the 4G and 5G carrier aggregation scenarios, the uplink carrier and the downlink carrier are configured in pairs, for example: uplink carrier 0 is associated with downlink carrier 0, uplink carrier 1 is associated with downlink carrier 1, and uplink carrier 2 is associated with downlink carrier 2. This association indicates that uplink carrier x will refer to downlink carrier x for uplink synchronization, and uplink carrier x and downlink carrier x will be transmitted on the same carrier. In addition, uplink carrier x can also be synchronized with downlink Pcell (primary carrier). For example: in the FDD frequency band, when the continuous spectrum is divided into 4 pairs of uplink and downlink carriers, corresponding to carrier 0, carrier 1, carrier 2, and carrier 3, respectively. 3. When carrier 0 is used as the Pcell, since there is no downlink service transmission on downlink carrier 3, but there is uplink service transmission on uplink carrier 3, in order to save energy, the downlink carrier may not transmit the downlink signal. At this time, according to the relevant technical solution, uplink carrier 3 only refers to the Pcell for association, and cannot refer to the nearest downlink carrier 2 for synchronization. Therefore, this paired carrier association or primary carrier association solution limits the synchronization performance of the uplink carrier; In addition, due to the different uplink and downlink service requirements, this also leads to different transmission requirements for uplink and downlink scheduling information, and different bandwidths corresponding to the uplink and downlink spectrum, which also leads to the corresponding DCI for uplink and downlink. The size of the format is different. If the uplink and downlink are transmitted on the same carrier, in order to reduce the number of blind detections by the terminal, the DCI Format size padding corresponding to the uplink and downlink carriers needs to be the same size, which results in a large amount of bit waste and also wastes the resources for transmitting these reserved bits; therefore, this scheme of transmitting the scheduling information of the uplink and downlink carriers on the same carrier has the problem of resource waste; in order to solve the above problem, the embodiment of the present application proposes to independently configure the downlink carrier for the uplink carrier, including: independently configuring the downlink carrier for synchronization with the uplink carrier, and or independently configuring the downlink carrier for transmitting its corresponding scheduling information.

[0099] For example: adding a reference downlink carrier ID (pathloss reference linking cell ID) to the uplink carrier, where the downlink carrier ID corresponds to 5 bits, 6 bits, 8 bits, or 36 bits to indicate its synchronization carrier; adding a reference downlink carrier ID to the downlink carrier so that when there is no downlink synchronization reference signal on the downlink carrier, selecting a downlink synchronization reference signal of another appropriate downlink carrier for measurement; independently configuring the uplink carrier to be used as a downlink carrier for transmitting its corresponding scheduling information, specifically including: configuring a downlink carrier for transmitting its uplink carrier scheduling information for each uplink DCI format of the uplink carrier, or configuring the uplink carrier to transmit its scheduled downlink carrier, or configuring the full-duplex carrier to transmit its uplink scheduled downlink carrier, or configuring the uplink sub-band of the full-duplex carrier to transmit its scheduled downlink carrier; independently configuring the downlink carrier to be used as a downlink carrier for transmitting its corresponding scheduling information, specifically including: configuring the downlink carrier for each downlink DCI format of the downlink carrier, format configures a downlink carrier for transmitting its scheduling information, or, for a downlink carrier, configures a downlink carrier for transmitting its scheduling, or, for a full-duplex carrier, configures a downlink carrier for transmitting its downlink scheduling, or, for a downlink subband of a full-duplex carrier, configures a downlink carrier for transmitting its scheduling; for a search space, configures a carrier index and or carrier type corresponding to its transmission scheduling information; wherein, the carrier type includes at least one of the following: uplink carrier, downlink carrier, full-duplex carrier, full-duplex subband carrier; if the carrier type corresponding to the scheduling information is a full-duplex carrier or a full-duplex subband carrier, the search space also needs to be configured with subband index information corresponding to its transmission scheduling information; for example: a full-duplex carrier, part or all of its frequency domain positions can be multiplexed for uplink and downlink transmissions, and a subband or part of the bandwidth (Bandwith) is separately defined for the frequency domain position for multiplexing uplink and downlink transmissions. Part, BWP), allocate subband or BWP identifier, define subband or BWP separately for frequency domain position of uplink or downlink transmission only, allocate subband or BWP identifier, configure relevant information for subband or BWP identifier, such as: frequency domain position, frequency domain bandwidth, its corresponding PDSCH or PUSCH configuration or PDCCH configuration, its corresponding reference signal configuration, etc.; a subband full-duplex carrier can be divided into multiple subbands, some subbands are uplink subbands, some subbands are downlink subbands, and relevant information is configured for each subband, such as : Synchronize the reference downlink carrier or the downlink subband on the subband full-duplex carrier, or, for all uplink subbands on the subband full-duplex carrier, jointly configure the downlink carrier or the downlink subband on the subband full-duplex carrier for transmitting its scheduling information, jointly configure the downlink carrier or the downlink subband on the subband full-duplex carrier for transmitting its scheduling information for all downlink subbands on the subband full-duplex carrier, or, configure the downlink carrier or the downlink subband on the subband full-duplex carrier for transmitting its scheduling information for all subbands (including uplink and downlink subbands) on the subband full-duplex carrier.The scheduling information corresponding to a sub-band full-duplex carrier or a full-duplex carrier can be transmitted on the downlink sub-band on its carrier, or on other downlink carriers, or on another sub-band full-duplex carrier or the downlink sub-band of a full-duplex carrier. The specific transmission carrier is configured by the base station, that is, the base station configures a scheduling information transmission carrier corresponding to a sub-band full-duplex carrier or a full-duplex carrier.

[0100] Uplink carriers are independently activated and deactivated; downlink carriers are independently activated and deactivated. When an uplink carrier is not configured with its downlink carrier, the downlink carrier can use the default carrier associated with the PCell, or the default carrier associated with the downlink carrier with the same index, or a downlink subband within a full-duplex carrier, or a specific downlink subband within a full-duplex carrier (such as downlink subband 0). If a downlink carrier with the same index exists, it is associated with the downlink carrier with the same index. If no downlink carrier with the same index exists, it is associated with the PCell.

[0101] For example, the SearchSpace IE includes a transmission carrier indication schedulingCellId, which is used to indicate the downlink carrier position corresponding to the search space.

[0102] The carrier index corresponding to the transmission scheduling information on the search space can be one or more (such as: carrier index set). When it corresponds to multiple, it is equivalent to aggregating multiple carriers together into a virtual carrier for scheduling; in general, there are two configuration methods for virtual carriers. One is to first configure the mapping relationship between carriers to form a new carrier index, and then configure the relevant configuration information for each carrier. For example, one method is to first virtualize multiple carrier indexes into a new carrier index, and schedule and configure the new carrier index. For example, there are separate carrier indexes #0, #1, #2, #3, and #4. Carrier indexes #0, #1, and #2 can be aggregated to form a new carrier index #5, carrier indexes #3 and #4 can be aggregated to form a new carrier index #6, and carrier indexes #0, #1, #2, #3, and #4 can be aggregated to form a new carrier index #7. The base station can configure the scheduling information or the carriers associated with the transmission scheduling information for carrier index #0 to carrier index #7 respectively; a terminal can detect the virtual carrier after multiple carriers are aggregated, or it can detect a single carrier, or it can detect the virtual carrier and the single carrier at the same time. Each carrier (virtual The search space of the virtual carrier (or a single carrier) is separately configured; the virtual carrier can be further divided into an uplink virtual carrier and a downlink virtual carrier, and the uplink virtual carrier and the downlink virtual carrier can be configured separately; for example: separate uplink carrier indexes #0, #1, #2, #3, #4, separate downlink carrier indexes #0, #1, #2, #3, uplink carrier indexes #0, #1, #2 are aggregated to form a new carrier index #5, the base station can configure the relevant carrier configuration information for uplink carriers #0, #1, #2, #3, #4, #5 respectively, specifically including at least one of the following: transmitting its modulation The downlink carrier for transmitting its scheduling information, its reference downlink synchronization carrier, BWP information, its frequency domain position information, and its associated PUSCH transmission configuration information; downlink carrier indexes #1 and #2 are aggregated to form a new carrier index #4. The base station can configure the relevant carrier configuration information for downlink carriers #0, #1, #2, #3, and #4 respectively, specifically including at least one of the following: the downlink carrier for transmitting its scheduling information, its reference downlink synchronization carrier, BWP information, its frequency domain position information, its associated PDSCH transmission configuration information, and its associated PDCCH search space configuration information. Another way is to form a virtual carrier through the carrier index information corresponding to the search space transmission scheduling information, such as: the carrier index corresponding to the transmission scheduling information configured for the search space is a carrier index set, and the index set corresponds to a virtual carrier; the two ways can also be used in combination.

[0103] The virtual carrier corresponds to the aforementioned jointly scheduled carrier, and the single carrier corresponds to the aforementioned independently scheduled carrier.
