As shown in FIG. 2, an embodiment of the present application provides a spectrum allocation method 200, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal, and the method includes the following steps.

S202: The terminal receives configuration information; the terminal is equipped with multiple smart cards, and the configuration information is used to adjust the frequency spectrum positions of the subcarriers used by the multiple smart cards.

The terminal mentioned in the various embodiments of this application may refer to a physical terminal equipped with multiple smart cards.

In addition, the smart card mentioned in the various embodiments of this application may not only be a physical card, but also a virtual card, such as an embedded chip-type subscriber identification card (Embedded-SIM, eSIM). Among the multiple smart cards carried by the terminal, each smart card can independently receive scheduling/configuration/power control commands of the network-side equipment, and transmit information under the control of the network-side equipment.

In this step, the terminal may receive the configuration information through any one or more smart cards among the multiple smart cards on board. The configuration information is used to adjust the frequency spectrum positions of the sub-carriers used by the multiple smart cards, for example, adjusting the sub-carriers used by the multiple smart cards to continuous sub-carriers in the frequency domain, so as to reduce the protection between the multiple sub-carriers interval (guardband) to improve spectrum utilization.

Optionally, in an example, the configuration information is used to instruct the subcarriers used by the plurality of smart cards to transmit information by means of carrier aggregation. In this way, the configuration information can be used to adjust the sub-carriers used by multiple smart cards to the same aggregated channel bandwidth (Aggregated Channel Bandwidth), so that the sub-carriers used by multiple smart cards can transmit information by means of carrier aggregation, which is convenient for improving the frequency spectrum. utilization.

It can be understood that, before S202, the network side device has already obtained the information of the multiple smart cards carried on the terminal.

Optionally, the configuration information is used to adjust the frequency spectrum positions of the subcarriers used by the multiple smart cards when they work simultaneously. When the multiple smart cards do not work at the same time, for example, when a terminal equipped with two smart cards takes out one smart card, the remaining smart card can also perform information (such as data, signaling, etc.) according to the predefined spectrum location in the smart card. )transmission. After S204, when the multiple smart cards transmit information at the same time, the information can be transmitted through the adjusted frequency spectrum position.

Optionally, after S204, the terminal may also send second indication information, where the second indication information is used to instruct the terminal to complete the adjustment of the frequency spectrum positions of the subcarriers used by the multiple smart cards, so that the network-side device and the terminal can adjust the frequency spectrum position. After the spectrum location for information transmission,

As mentioned in the foregoing embodiment, the configuration information received by the terminal is used to instruct the subcarriers used by multiple smart cards to transmit information by means of carrier aggregation, and the carrier aggregation may be in-band continuous carrier aggregation. In this embodiment, through the transmission mode of in-band continuous carrier aggregation, the sub-carrier corresponding to each smart card can be used as a carrier unit of in-band carrier aggregation. At this time, the protection bandwidth between two adjacent carrier units can be reduced. Through this method The spectrum utilization can be improved.

Optionally, there is a one-to-one correspondence between the sub-carriers used when each smart card works independently (eg, the sub-carriers determined according to the built-in information of the smart card) and the sub-carriers used in the mode of carrier aggregation.

Optionally, the configuration information is further used to configure parameters of the carrier aggregation, and the parameters include at least one of the following: the correspondence between the multiple smart cards and the subcarriers used by the multiple smart cards; aggregation The nominal channel spacing between adjacent subcarriers within the carrier bandwidth; the channel grid position of each subcarrier within the aggregated carrier bandwidth; the synchronization grid position within the aggregated carrier bandwidth.

Optionally, after the terminal adjusts the frequency spectrum positions of the subcarriers used by the plurality of smart cards according to the configuration information, the method further includes: the terminal controls the subcarriers used by the plurality of smart cards to pass carrier aggregation. way to transmit information.

Optionally, the public land mobile networks (Public Land Mobile Network, PLMN) to which the multiple smart cards belong are the same, that is, the operators to which the multiple smart cards belong are the same, which is convenient for the subcarriers used by the multiple smart cards to carry out information by means of carrier aggregation. transmission.

The PLMNs to which the multiple smart cards belong are the same, specifically, at least one of the registered PLMNs or the equivalent PLMNs of the multiple smart cards is the same. For example, the registered PLMNs and the equivalent PLMNs of the plurality of smart cards are all the same; or, one of the registered PLMNs or the equivalent PLMNs of the plurality of smart cards is the same.

As mentioned in the foregoing embodiment, the configuration information received by the terminal is used to instruct the subcarriers used by multiple smart cards to transmit information by means of carrier aggregation, and the principle will be described below.

In this embodiment, for a scenario in which the same terminal is equipped with multiple smart cards (the SIM card will be used as an example for the following description) to access the communication system, if the network side device learns that the multiple SIM cards are located in the same terminal, and each SIM card selected The frequency band is suitable for carrier aggregation scenarios (for example, multiple SIM cards belong to the same operator). At this time, the network side device can adjust the sub-carriers used by each SIM card for communication, so that multiple SIM cards work in the mode of in-band carrier aggregation. .

Specifically, in an example, if multiple SIM cards belong to the same operator and the working frequency bands of each SIM card meet the requirements of in-band continuous carrier aggregation, and the multiple SIM cards work in the same terminal, then through system configuration, The working sub-carriers (or working frequency bands) corresponding to the multiple SIM cards are made to work in the mode of in-band carrier aggregation, so as to transmit the data of the multiple SIM cards.

The advantages of the above method are: if each SIM card works independently on its corresponding sub-carrier, both ends of the sub-carrier need to meet the requirements of the guard bandwidth, a large number of guard intervals are reserved, and the spectrum utilization rate is low. In this embodiment, through in-band carrier aggregation, the sub-carrier corresponding to each SIM card can be used as a carrier unit of in-band carrier aggregation. At this time, the protection bandwidth between two adjacent carrier units can be reduced. This method can bring Gain as follows:

1) When the protection bandwidth between adjacent carrier units is reduced, there is room to increase the protection bandwidth on both sides of the entire aggregated carrier bandwidth (Aggregated Channel Bandwidth) to better resist the interference of adjacent frequency bands and reduce the Interference in adjacent frequency bands.

2) When dealing with each SIM card separately, in some cases, the maximum transmission bandwidth configuration cannot be fully utilized. By reducing the protection bandwidth between adjacent carrier units by the above method, it is possible to directly increase the use of SIM cards. bandwidth, improve spectrum utilization, and increase system throughput.

3) The carrier aggregation function can be used for data transmission of multiple SIM cards, and the carrier aggregation related features, such as cross-carrier scheduling, etc., can be used to improve the system throughput.

The network side device provides instructions (such as the configuration information mentioned in the previous embodiment), notifying the terminal that the subcarriers used by each SIM card can work in the mode of in-band continuous carrier aggregation, and at the same time notifying the correspondence between the SIM card and the subcarriers. There is a one-to-one correspondence between the frequency bands (or sub-carriers) used by each SIM card when it works independently and the carrier unit when it works in the carrier aggregation mode.

The network-side device may also send parameters for carrier aggregation spectrum configuration to the terminal in an instruction (such as the configuration information mentioned in the previous embodiment), such as the nominal channel spacing between adjacent carrier units, and each sub-carrier The channel raster position of the carrier, the synchronization raster position, etc.

Subsequently, the terminal adjusts the frequency spectrum position of each subcarrier as required according to the instruction of the network side device.

The terminal reports the adjusted reconfiguration completion message (such as the second indication information in the foregoing) to the network side device.
