The embodiment of the application provides a method and a device for reconfiguring a target cell, which are used for a terminal device to send indication information to a network device to indicate a frequency point allocated by the network device, which is not supported by the terminal device, so that the network device does not indicate the terminal device to reconfigure the target cell by the frequency point any more, and the success rate of reconfiguring the cell is improved.
The terminal device provided in the embodiments of the present application may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), and the like, which is not limited in this embodiment of the present application.
The network device provided in this embodiment of the present application may be a device for communicating with a terminal device, where the network device may be a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) system or a Code Division Multiple Access (CDMA) system, may also be a base station (nodeB) in a Wideband Code Division Multiple Access (WCDMA) system, may also be an evolved node b (eNB) or eNodeB) in an LTE system, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN, and the like.
The embodiment of the application can be applied to various communication systems, such as: a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a long term evolution (long term evolution, LTE) system, a LTE Frequency Division Duplex (FDD) system, a LTE Time Division Duplex (TDD) system, a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a fifth generation (5G) system, or a new radio network (UMTS) NR, etc.
Referring to fig. 1a, fig. 1a is a schematic view of an embodiment provided in an embodiment of the present application, as shown in fig. 1, the schematic view of the embodiment includes a terminal device and a network device, where information interaction between the terminal device and the network device may be as shown in fig. 1 b.
As shown in fig. 1b, the network device sends a capability query message to the terminal device; the terminal device receives a capability query message sent by the network device and sends a capability report message to the network device, wherein the frequency band capability reported by the capability report message only has frequency band information and does not have frequency band range information, so that the network device cannot know the frequency spectrum condition actually supported by the terminal device. For example, the frequency band supported by the terminal device is B42, the frequency spectrum range supporting B42 is 3400-3600MHz, the frequency band supported by the terminal device is reported by the capability report message as B42, and the frequency spectrum range supported by the terminal device is not reported by the capability report message as 3400-3600MHz, it needs to be pointed out that the capability report message may also report that the frequency bands supported by the terminal device may also include other frequency bands, for example, the frequency band B41.
The network device may obtain the frequency bands supported by the terminal device from the capability reporting message of the terminal device, for example, determine the frequency bands B42 and B41 supported by the terminal device from the capability reporting message; the network device may register a primary cell (PCell) in the frequency band B41, and perform RRC communication with the terminal device through the PCell.
The network device may also send a reconfiguration message to the terminal device through the RRC to instruct the terminal device to reconfigure the target cell at the frequency point of the target cell, where the frequency point of the target cell may be any frequency point in the frequency band 42, for example, a secondary cell (SCell) is configured at the frequency point of the frequency band 42.
As communication technologies develop, the spectrum range under 5G is wider, for example, the spectrum range of the gold band n77 of FR1 reaches 900M, and the spectrum range of FR2 reaches 3000MHZ, such a wide spectrum is generally not exclusive to an operator, such as soft silver, KDDI, medium mobility, etc., the spectrum customization is made to the band range of the UE at 4G, and the possibility of customizing the spectrum range under 5G is very large.
The allocation of the spectrum resources of the operator is not constant, for example, the operator may expand the initial spectrum range 3400-.
For example, when the frequency point of the target cell indicated by the reconfiguration message is within the frequency spectrum range of 3200-; in a non-measurement scenario, since the terminal device cannot identify the frequency point of the target cell, the network device repeatedly triggers reconfiguration, for example, when the frequency point of the target cell is within the frequency spectrum range of 3200-3400MHz, the terminal device and the network device continuously repeat the cycle shown in fig. 1b, so that the terminal device cannot normally perform a service.
One embodiment of the present application is schematically described above, and a method for reconfiguring a target cell provided in the embodiment of the present application is described below.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for reconfiguring a target cell according to an embodiment of the present application, and as shown in fig. 2, the schematic flowchart may include the following steps:
201. the network device sends a capability query message to the terminal device.
202. And the terminal equipment sends a capability reporting message to the network equipment.
The terminal device receives a capability query message sent by the network device, and sends a capability report message to the network device according to the capability query message, where the capability report message includes frequency bands supported by the terminal device, for example, the capability report message indicates that the terminal device supports frequency bands B41 and B42.
203. And registering the PCell.
And the network equipment determines the frequency band supported by the terminal equipment from the capability report message, and registers the PCell in the frequency band supported by the terminal equipment. For example, the PCell is registered in the frequency band B41 indicated by the capability reporting message.
204. The network device sends a first message to the terminal device.
The network device performs Radio Resource Control (RRC) connection with the terminal device at the PCell, and the network device sends a first message to the terminal device through the RRC connection, where the first message indicates that the target cell is reconfigured at a first frequency point of the target cell, for example, the first message indicates that the terminal device configures the SCell at the first frequency point, where the first frequency point may be a frequency spectrum range 3200 and 3600MHz middle frequency point of a frequency band B42.
It should be noted that, in this embodiment, the first message may be a reconfiguration message, or may also be a feedback message or other message sent by the network device to the terminal device, which is not limited herein. In this embodiment and the following embodiments, only the first message may be taken as a reconfiguration message for example.
Optionally, in a possible implementation manner, the first message further indicates at least one of a first bandwidth of the target cell and a first subcarrier interval of the target cell, and this embodiment takes the example that the first message further indicates the first bandwidth of the target cell and the first subcarrier interval of the target cell as an example.
205. And the terminal equipment sends a second message to the network equipment.
The terminal equipment receives a first message sent by the network equipment, determines a first frequency point of a target cell from the first message, judges whether the first frequency point is in a frequency spectrum range supported by the terminal equipment, and sends a second message to the network equipment when the terminal equipment determines that the first frequency point is not in the frequency spectrum range supported by the terminal equipment, wherein the second message indicates that the terminal equipment does not support the first frequency point.
For example, the terminal device determines, from the first message, that the first frequency point is the frequency point in the frequency band B42, and then determines whether the first frequency point is in the spectrum range 3400 plus 3600MHz that the terminal device supports, and when the first frequency point is not in the spectrum range 3400 plus 3600MHz, for example, the first frequency point is in the spectrum range 3200 plus 3400MHz, the terminal device sends the second message to the network device, so as to indicate that the terminal device does not support the first frequency point.
It should be noted that, in this embodiment, the second message may be a reconfiguration request message, or may also be a feedback message or other message sent by the terminal device to the network device, which is not limited herein.
Optionally, in a possible implementation manner, when the first message further indicates the first bandwidth of the target cell and the first subcarrier spacing of the target cell, the terminal device further determines whether the first bandwidth is in a bandwidth set supported by the terminal device and whether the first subcarrier spacing is in a subcarrier spacing set supported by the terminal device. The second message also indicates that the terminal device does not support the first bandwidth when the first bandwidth is not within the set of bandwidths supported by the terminal device. The second message also indicates that the terminal device does not support the first subcarrier spacing when the first subcarrier spacing is not within the set of subcarrier spacings supported by the terminal device.
206. And the network equipment sends a third message to the terminal equipment.
And the network equipment receives a second message sent by the terminal equipment and determines that the terminal equipment does not support the first frequency point from the indication information of the second message, namely determines that the first frequency point is an invalid frequency point on the terminal equipment side.
And the network equipment determines a second frequency point from the frequency band supported by the terminal equipment, wherein the second frequency point is different from the first frequency point, and the network equipment indicates the terminal equipment to reconfigure the target cell with the second frequency point of the target cell by sending a third message to the terminal equipment. For example, the network device determines a second frequency point different from the first point from the frequency spectrum range 3200-3600MHz of B42, and triggers the terminal device to configure the SCell at the second frequency point through a third message.
It is to be understood that the third message may be a reconfiguration message, or may also be a feedback message or other message sent by the network device to the terminal device, which is not limited herein.
It should be noted that the first message and the third message in this example may be the same type of messages, for example, both the first message and the third message may be reconfiguration messages, where the first message instructs the terminal device to reconfigure the target cell at the first frequency point of the target cell, and the third message instructs the terminal device to reconfigure the target cell at the second frequency point of the target cell.
Optionally, in a possible implementation manner, when the network device further determines that the terminal device does not support the first bandwidth and the terminal device does not support the first subcarrier spacing from the second message, the network device further determines a second bandwidth from the bandwidth set of the target cell and a second subcarrier spacing from the subcarrier spacing set of the target cell, and indicates the second bandwidth and the second subcarrier spacing of the target cell through a third message, where the second bandwidth is different from the first bandwidth and the second subcarrier spacing is different from the first subcarrier spacing.
207. And reconfiguring the target cell.
And the terminal equipment receives a third message sent by the network equipment and determines a second frequency point of the target cell from the third message, judges whether the second frequency point is in a frequency spectrum range supported by the terminal equipment, and reconfigures the target cell by the terminal equipment with the second frequency point when the second frequency point is in the frequency spectrum range supported by the terminal equipment.
For example, the terminal device determines, from the third message, that the second frequency point is the frequency point in the frequency band B42, and then determines whether the second frequency point is in the supported spectrum range 3400-3600MHz, and when the second frequency point is in the spectrum range 3400-3600MHz, the terminal device reconfigures the target cell with the second frequency point.
It can be understood that, when the second frequency point is in the frequency spectrum range 3200-.
Optionally, in a possible implementation manner, when the third indication information further indicates a second bandwidth and a second subcarrier interval of the target cell, the terminal device further determines whether the second bandwidth is in a bandwidth set supported by the terminal device, and further determines whether the second subcarrier interval is in a subcarrier interval set supported by the terminal device, and when the second bandwidth is in the bandwidth set supported by the terminal device and the second subcarrier interval is in the subcarrier interval set supported by the terminal device, the terminal device reconfigures the target cell with the second frequency point, the second bandwidth, and the second subcarrier interval.
It can be understood that, if the terminal device determines that the second bandwidth is not in the set of bandwidths supported by the terminal device and/or the second subcarrier spacing is not in the set of subcarrier spacings supported by the terminal device, the terminal device may also send a message to the terminal device indicating that the terminal device does not support the second bandwidth and/or the second subcarrier spacing, thereby triggering the network device to instruct the terminal device to reconfigure the target cell with a bandwidth different from the first bandwidth and the second bandwidth and/or a subcarrier spacing different from the first subcarrier spacing and the second subcarrier spacing.
In this embodiment, the terminal device determines that the first frequency point indicated by the first message is a frequency point that is not supported by the terminal device, and the terminal device indicates that the terminal device does not support the first frequency point by sending the second message to the network device, so that the network device indicates the terminal device to reconfigure the target cell at the second frequency point different from the first frequency point. Therefore, in this example, after the network device determines that the terminal device does not support the first frequency point, the network device may not reconfigure the measurement of the first frequency point or may not repeat the step of instructing the terminal device to reconfigure the target cell with the first frequency point, but trigger the terminal device to reconfigure the target cell with a second frequency point different from the first frequency point, thereby improving the success rate of reconfiguring the target cell.
The above describes a method for reconfiguring a target cell provided in an embodiment of the present application, and the following describes another method for reconfiguring a target cell provided in an embodiment of the present application.
In this embodiment, the first reconfiguration message is taken as a first message, the reconfiguration request message is taken as a second message, and the second reconfiguration message is taken as a third message.
Referring to fig. 3, fig. 3 is a schematic flowchart of another method for reconfiguring a target cell according to an embodiment of the present application, and as shown in fig. 3, the schematic flowchart may include the following steps:
301. the network device sends a capability query message to the terminal device.
302. And the terminal equipment sends a capability reporting message to the network equipment.
303. And registering the PCell.
In this embodiment, steps 301 to 303 are similar to steps 201 to 203 of the embodiment shown in fig. 2, and are not described again here.
304. The network device sends a first reconfiguration message to the terminal device.
The network device performs RRC connection with the terminal device in the PCell, and sends a first reconfiguration message to the terminal device through the RRC connection, where the first reconfiguration message instructs the terminal device to reconfigure the target cell at a first frequency point of the target cell, for example, the first reconfiguration message instructs the terminal device to configure the SCell at a first frequency point, where the first frequency point may be a middle frequency point of 3200 and 3400MHz in a frequency spectrum range of B42.
Optionally, in a possible implementation manner, the first reconfiguration message further indicates at least one of the first bandwidth of the target cell and the first subcarrier interval of the target cell, and this embodiment takes the example that the first reconfiguration message further indicates the first bandwidth of the target cell and the first subcarrier interval of the target cell as an example.
305. The terminal equipment sends a reconfiguration request message to the network equipment.
The method comprises the steps that terminal equipment receives a first reconfiguration message sent by network equipment, determines a first frequency point of a target cell from the first reconfiguration message, judges whether the first frequency point is in a frequency spectrum range supported by the terminal equipment, and sends a reconfiguration request message to the network equipment when the terminal equipment determines that the first frequency point is not in the frequency spectrum range supported by the terminal equipment, wherein the reconfiguration request message indicates the frequency spectrum range supported by the terminal equipment.
For example, the terminal device determines, from the first reconfiguration message, that the first frequency point is the frequency point in the frequency band B42, and then determines whether the first frequency point is in the spectrum range 3400-3600MHz supported by the terminal device, and when the first frequency point is not in the spectrum range 3400-3600MHz, for example, the first frequency point is in the spectrum range 3200-3400MHz, the terminal device sends a reconfiguration request message to the network device, where the reconfiguration request message indicates the spectrum range supported by the terminal device, for example, the reconfiguration message indicates the spectrum range 3400-3600MHz of B42, and of course, the terminal device may also support the spectrum ranges of other frequency bands supported by the terminal device, for example, the spectrum range 3300-3500MHz of the frequency band n 77.
Specifically, the terminal device carries a signaling element (IE) in the reconfiguration request message, and the IE indicates the spectrum range supported by the terminal device, where it needs to be noted that the IE may be an IE newly added to the reconfiguration request message or another IE in the reconfiguration request message.
The following describes the format of the IE carried by the reconfiguration request message by taking the frequency spectrum range supported by the terminal device, which is the frequency spectrum range 3300-3500MHz of the frequency band n77 and the frequency spectrum range 3400-3680MHz of the frequency band B42.
In this embodiment, the terminal device may include the frequency spectrum range [ 3300-. Specifically, referring to fig. 4, the IE format shown in fig. 4 indicates the supported spectrum range of the terminal device in the downlink frequency, the IE shown in fig. 4 may include the frequency band n77 supported by the terminal device and the supported spectrum range [ 3300-. Referring to fig. 5, the IE format shown in fig. 5 indicates the supported spectrum range of the terminal device by using the downlink frequency point number, the IE shown in fig. 5 may include the frequency band n77 supported by the terminal device and the supported spectrum range [ 620000-.
It should be noted that, in practical applications, the frequency spectrum range supported by the terminal device may include two or more portions. For example, in the frequency band B42, the frequency spectrum ranges supported by the terminal device include [ 3400-. The IE format shown in FIG. 7 indicates the supported spectrum ranges [41590-42390] and (42390-43590 ] of the terminal equipment by the downlink frequency point number.
Optionally, in a possible implementation manner, the IE carried in the reconfiguration request message may further include a bandwidth set supported by the terminal device and/or a subcarrier spacing set supported by the terminal device. When the IE carried by the reconfiguration request message may further include the bandwidth set supported by the terminal device, the format of the IE carried by the reconfiguration request message may be as shown in fig. 8 or fig. 9, and it can be understood that, in Long Term Evolution (LTE), for a frequency band n77, the bandwidths supported by the terminal device are 20M and 40M, and then the bandwidth supported by the terminal device indicated by the IE is 288. When the IE carried by the reconfiguration request message may further include a set of subcarrier intervals supported by the terminal device, a format of the IE carried by the reconfiguration request message may be as shown in fig. 10 or fig. 11, it may be understood that in LTE, the subcarrier interval supported by the terminal device is 15KHz, and of course, in a 5G or future evolved system, the subcarrier interval supported by the terminal device may also be other, such as 30KHz, 45KHz, or 60KHz, and the like, which is not limited herein. When the IE carried by the reconfiguration request message may further include a bandwidth set supported by the terminal device and a subcarrier spacing set supported by the terminal device, the format of the IE carried by the reconfiguration request message may be as shown in fig. 12 or fig. 13.
It should be noted that the frequency spectrum range supported by the terminal device may include two or more parts, for example, in the frequency band B42, the frequency spectrum range supported by the terminal device includes [ 3400-. For example, in the fifth Generation mobile communication technology (5th-Generation, 5G), when the spectrum range supported by the terminal device is [ 3400-. Fig. 14 indicates the frequency spectrum range and the bandwidth set supported by the terminal device with downlink frequency, fig. 15 indicates the frequency spectrum range and the bandwidth set supported by the terminal device with downlink frequency point numbers, fig. 16 indicates the frequency spectrum range, the bandwidth set, and the subcarrier interval set supported by the terminal device with downlink frequency, and fig. 17 indicates the frequency spectrum range, the bandwidth set, and the subcarrier interval set supported by the terminal device with downlink frequency point numbers.
