Referring to fig. 1a, fig. 1a is a schematic diagram of an embodiment provided in an embodiment of the present application, as shown in fig. 1a, where the embodiment schematically includes a terminal device and a network device, and information interaction between the terminal device and the network device may be shown in fig. 1 b.
As shown in fig. 1b, the network device sends a capability query message to the terminal device; the terminal equipment receives the capability query message sent by the network equipment and sends a capability report message to the network equipment, wherein the frequency band capability reported by the capability report message is only frequency band information, and the frequency band range information is not available, so that the network equipment cannot know the actual supported frequency spectrum condition of the terminal equipment. For example, the frequency band supported by the terminal device is B42, and the frequency spectrum range supporting B42 is 3400-3600MHz, and the frequency band supported by the terminal device is B42 and does not report the frequency spectrum range 3400-3600MHz supported by the terminal device, and it should be noted that the frequency band supported by the terminal device may also include other frequency bands, for example, the frequency band B41.
The network device may learn the frequency band supported by the terminal device from the capability report message of the terminal device, for example, determine the frequency bands B42 and B41 supported by the terminal device from the capability report message; the network device may register a primary cell (PCell) in a 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 RRC to instruct the terminal device to reconfigure the target cell with a 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, configure a secondary cell (SCell) with a frequency point of the frequency band 42.
With the development of communication technology, the spectrum range under 5G is wider, for example, the spectrum range of the golden band n77 of FR1 reaches 900M, while the spectrum range of FR2 reaches 3000MHZ, which is a wide spectrum that is not generally monopolized by an operator, such as soft silver, KDDI, medium mobility, etc., and the spectrum customization is performed on the frequency band range of UE under 4G, so that 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 extend the initial spectrum range 3400-3600MHz of the frequency band B42 to 3200-3600MHz, and the existing terminal device does not support the extended spectrum range 3200-3400 MHz, so that the operator adjusts the spectrum range to cause great impact on the existing terminal device.
For example, when the frequency point of the target cell indicated by the reconfiguration message is in the spectrum range 3200-3400 MHz, in the measurement scenario, the terminal device does not respond to the network device, ignores the frequency point of the target cell indicated by the reconfiguration message, does not reconfigure the cell, and causes the network device to repeatedly configure the measurement; in the non-measurement scenario, the terminal device cannot identify the frequency point of the target cell, so that the network device repeatedly triggers reconfiguration, for example, when the frequency point of the target cell is in the frequency spectrum range 3200-3400 MHz, the terminal device and the network device continuously repeat the cycle shown in fig. 1b, so that the terminal device cannot normally develop the service.
Having described an embodiment of the present application schematically, embodiments of the present application are provided below A method for reconfiguring a target cell is described.
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, 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. The terminal device sends a capability report message to the network device.
The terminal device receives the 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 a frequency band supported by the terminal device, for example, the capability report message indicates that the terminal device supports frequency bands B41 and B42.
203. The PCell is registered.
The network device determines the frequency band supported by the terminal device from the capability report message, and registers the PCell with the frequency band supported by the terminal device. For example, the PCell is registered with the band B41 indicated by the capability report message.
204. The network device sends a first message to the terminal device.
The network device performs radio resource control (radio resource control, RRC) connection between the PCell and the terminal device, and the network device sends a first message to the terminal device through RRC connection, where the first message indicates that the target cell is reconfigured with a first frequency point of the target cell, for example, the first message indicates that the terminal device configures the SCell with the first frequency point, where the first frequency point may be a middle frequency point in a frequency spectrum range 3200-3600 MHz of a frequency band B42.
It should be noted that, in this embodiment, the first message may be a reconfiguration message, or may be a feedback message or other messages sent by the network device to the terminal device, which is not limited herein. This embodiment and the following embodiments only take the first message as an example of the reconfiguration message.
Optionally, in one possible implementation manner, the first message further indicates at least one of a first bandwidth of the target cell and a first subcarrier spacing of the target cell, and this embodiment is described taking the first message further indicates the first bandwidth of the target cell and the first subcarrier spacing of the target cell as an example.
205. The terminal device sends a second message to the network device.
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 that the first frequency point is a frequency point in the frequency band B42 from the first message, then determines whether the first frequency point is in the supported frequency spectrum range 3400-3600MHz, and when the first frequency point is not in the supported frequency spectrum range 3400-3600MHz, for example, when the first frequency point is in the frequency spectrum range 3200-3400MHz, the terminal device sends a second message to the network device 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 be a feedback message or other messages sent by the terminal device to the network device, which is not limited herein.
Optionally, in one possible implementation, 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 within a bandwidth set supported by the terminal device and whether the first subcarrier spacing is within 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 a set of subcarrier spacing supported by the terminal device.
206. The network device sends a third message to the terminal device.
The network equipment receives the 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 at the terminal equipment side.
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 instructs 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 spectrum range 3200-3600MHz of B42, and triggers the terminal device to configure the SCell with the second frequency point through the third message.
It is to be understood that the third message may be a reconfiguration message, or may 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, in this example, the first message and the third message may be the same type of messages, for example, both the first message and the third message may refer to reconfiguration messages, where the first message indicates that the terminal device reconfigures the target cell with the first frequency point of the target cell, and the third message indicates that the terminal device reconfigures the target cell with the second frequency point of the target cell.
Optionally, in one possible implementation, when the network device further determines from the second message that the terminal device does not support the first bandwidth and the terminal device does not support the first subcarrier spacing, the network device further determines a second bandwidth from the bandwidth set of the target cell and determines a second subcarrier spacing from the subcarrier spacing set of the target cell, and indicates, through the third message, the second bandwidth and the second subcarrier spacing of the target cell, where the second bandwidth is different from the first bandwidth and the second subcarrier spacing is different from the first subcarrier spacing.
207. The target cell is reconfigured.
The terminal equipment receives the third message sent by the network equipment, 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 when the second frequency point is in the frequency spectrum range supported by the terminal equipment, the terminal equipment reconfigures the target cell by the second frequency point.
For example, the terminal device determines that the second frequency point is a frequency point in the frequency band B42 from the third message, then determines whether the second frequency point is in the supported frequency spectrum range 3400-3600MHz, and when the second frequency point is in the frequency spectrum range 3400-3600MHz, the terminal device reconfigures the target cell with the second frequency point.
It can be appreciated that when the second frequency point is in the spectrum range 3200-3400, the terminal device determines that the second frequency point is not in the spectrum range supported by the terminal device, and the terminal device may further send a message to instruct the terminal device not to support the second frequency point, thereby triggering the network device to reconfigure the target cell with a frequency point different from the first frequency point and the second frequency point.
Optionally, in one possible implementation manner, when the third indication information further indicates the second bandwidth and the second subcarrier spacing 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 spacing is in a subcarrier spacing 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 spacing is in the subcarrier spacing 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 spacing.
It will be appreciated 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 different bandwidth than the first bandwidth and the second bandwidth and/or 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 a second message to the network device, so that the network device indicates the terminal device to reconfigure the target cell with a 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 does not reconfigure the measurement of the first frequency point or does not repeat to instruct the terminal device to reconfigure the target cell by the first frequency point, but triggers the terminal device to reconfigure the target cell by a second frequency point different from the first frequency point, thereby improving the success rate of reconfiguring the target cell.
The method for reconfiguring the target cell provided in the embodiment of the present application is described above, and another method for reconfiguring the target cell provided in the embodiment of the present application is described below.
In this embodiment, the present embodiment is described taking the first reconfiguration message as the first message, the reconfiguration request message as the second message, and the second reconfiguration message as the third message as an example.
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, 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. The terminal device sends a capability report message to the network device.
303. The PCell is registered.
In this embodiment, steps 301 to 303 are similar to steps 201 to 203 of the embodiment shown in fig. 2, and are not repeated here.
304. The network device sends a first reconfiguration message to the terminal device.
The network device performs RRC connection between the PCell and the terminal device, and sends a first reconfiguration message to the terminal device through the RRC connection, where the first reconfiguration message indicates that the terminal device reconfigures the target cell with a first frequency point of the target cell, for example, the first reconfiguration message indicates that the terminal device configures the SCell with the first frequency point, and the first frequency point may be an intermediate frequency point in a frequency spectrum range 3200-3400 MHz of the frequency band B42.
Optionally, in one possible implementation manner, the first reconfiguration message further indicates at least one of a first bandwidth of the target cell and a first subcarrier spacing of the target cell, and this embodiment is described taking as an example that the first reconfiguration message further indicates the first bandwidth of the target cell and the first subcarrier spacing of the target cell.
305. The terminal device sends a reconfiguration request message to the network device.
The terminal equipment receives a first reconfiguration message sent by the 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 that the first frequency point is a frequency point in the frequency band B42 from the first reconfiguration message, then determines whether the first frequency point is in a frequency spectrum range 3400-3600MHz supported by the first frequency point, and when the first frequency point is not in the frequency spectrum range 3400-3600MHz, for example, the first frequency point is in the frequency spectrum range 3200-3400MHz, the terminal device sends a reconfiguration request message to the network device, where the reconfiguration request message indicates the frequency spectrum range supported by the terminal device, for example, the reconfiguration message indicates the frequency spectrum range 3400-3600MHz of the B42, and of course, the frequency spectrum range of other frequency bands supported by the terminal device, for example, the frequency spectrum range 3300-3500MHz of the frequency band n77 can also be supported.
Specifically, the terminal device carries a signaling element (information element, IE) in the reconfiguration request message, and the IE indicates the spectrum range supported by the terminal device, which needs to be described, where the IE may be a new IE in the reconfiguration request message or may be other IEs in the reconfiguration request message.
The format of the IE carried by the reconfiguration request message will be described below taking the frequency spectrum ranges 3300 to 3500MHz in the frequency band n77 and 3400 to 3680MHz in the frequency band B42 as the frequency spectrum ranges supported by the terminal device as an example.
In this embodiment, the terminal device may include the spectrum range [3300-3500] supported by the terminal device in the IE with the downlink frequency or the downlink frequency number. Specifically, referring to fig. 4, the IE format shown in fig. 4 indicates a spectrum range supported by the terminal device with a downlink frequency, and as shown in fig. 4, the IE may include a frequency band n77 supported by the terminal device and a spectrum range [3300-3500] supported by the terminal device, and the terminal device may indicate the spectrum range supported by the terminal device through the IE shown in fig. 4. Referring to fig. 5, the IE format shown in fig. 5 indicates the spectrum range supported by the terminal device by using the downlink frequency point number, and as shown in fig. 5, the IE may include a frequency band n77 supported by the terminal device and a spectrum range [ 62000-633333 ] supported by the terminal device, and the terminal device may also indicate the spectrum range supported by the terminal device through the IE shown in fig. 5.
It should be noted that, in practical applications, the spectrum range supported by the terminal device may include two or more portions. For example, in the band B42, the spectrum ranges supported by the terminal device include [3400-3480] and (3480-3600), and the format of the IE carried by the reconfiguration request message may be as shown in fig. 6 or fig. 7, where the format of the IE shown in fig. 6 is that the spectrum ranges supported by the terminal device [3400-3480] and (3480-3600) are indicated by the downlink frequency. The IE format shown in fig. 7 indicates the supported spectral ranges of the terminal device [41590-42390] and (42390-43590) in downlink frequency bin numbers.
Optionally, in a possible implementation manner, the IE carried by the reconfiguration request message may further include a set of bandwidths supported by the terminal device and/or a set of subcarrier intervals supported by the terminal device. When the IE carried by the reconfiguration request message may further include a 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 may be understood that, in long term evolution (long term evolution, LTE), for the frequency band n77, the bandwidths supported by the terminal device are 20M and 40M, and 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 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. 10 or fig. 11, it may be understood that, in LTE, the subcarrier spacing supported by the terminal device is 15KHz, and of course, in a 5G or future evolution system, the subcarrier spacing supported by the terminal device may also be other, for example, 30 KHz,45 KHz or 60KHz, 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.
