Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of communications technologies, and in particular, to a method for configuring transmit power, a terminal, a base station, and a baseband chip.
[ background of the invention ]
With the continuous development of wireless communication technology, spectrum resources are increasingly scarce, and the existing spectrum resources are generally allocated in a licensed manner and an unlicensed manner. Among them, since it is difficult to complete the frequency clearing operation in a short time for the allocated spectrum, it is very necessary to develop a spectrum sharing access method for providing more accessible spectrum. Currently, commonly used spectrum sharing access methods include: an LSA (Licensed Shared Access) mode, an SAS (Spectrum Access system) mode, and an sgxgp mode.
In the related art, the SAS system and the LSA system perform coexistence of a plurality of systems through a third-party database, and share a spectrum through predefined cooperation conditions, such as allowing a low-priority system to share access to the spectrum when a high-priority system does not use the spectrum in a specific area or at a specific time.
In the sXGP system, when an sXGP terminal accesses the sXGP base station, the sXGP base station firstly obtains the surrounding interference environment through carrier sensing so as to determine the transmission power of the sXGP base station and the sXGP terminal, and if the sensed interference value is larger, the transmission power of the sXGP base station and the sXGP terminal is correspondingly reduced. Meanwhile, the sggp system also allows a 3GPP (3rd generation partnership Project) terminal to access the sggp base station, and the out-band radiation of the 3GPP terminal is higher than that of the sggp terminal, so that the out-band radiation of the 3GPP standard terminal is higher than that of the sggp terminal under the same transmission power, and further, the out-band system may generate a large interference.
Therefore, how to configure the transmission power of the communication device in the spectrum sharing process and reduce the interference to the out-of-band system becomes a technical problem to be solved urgently at present.

[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the technical solution of the embodiment of the present invention, after the base station zai obtains the interference environment information and the type of the user terminal, it calculates the first transmission power corresponding to the type of the user terminal, and notifies the first transmission power to the specified user terminal in the service area in a specified manner, and after receiving the first transmission power notified by the base station, the user terminal determines the second transmission power according to the first transmission power and the type of the user terminal, thereby completing the configuration of the maximum transmission power. The technical solution of the present invention will be described in detail from the base station side and the terminal side, respectively, by the following examples.
Example one
Fig. 1 shows a flowchart of a configuration method of transmission power according to an embodiment of the present invention.
As shown in fig. 1, a method for configuring transmit power according to an embodiment of the present invention includes:
step S101, obtaining interference environment information and user terminal type.
Under the same transmitting power, the out-of-band radiation of different types of terminals has certain difference, and when the out-of-band radiation is higher, the terminal can generate larger interference to an out-of-band system, so that the transmitting power is configured by taking the interference environment information and the type of the user terminal as parameters.
Step S102, calculating a first transmitting power corresponding to the user terminal type according to the interference environment information and the user terminal type.
In the embodiment, under the condition of considering an interference environment, parameter optimization is simultaneously performed on different terminal types, so that relatively reasonable sending power can be configured on different types, and the interference of different terminal types on an out-of-band system is reduced.
Step S103, notifying the first transmission power to the appointed user terminal in the service area in an appointed mode.
And after the first sending power is calculated, the first sending power is notified to an appointed user terminal in a service area in a mode of broadcast message, multicast message or unicast message, wherein the appointed user terminal is a user terminal connected with the base station in the service range of the base station.
According to the technical scheme of the embodiment, firstly, interference environment information and a user terminal type are obtained, then, first sending power corresponding to the user terminal type is calculated according to the interference environment information and the user terminal type, and finally, the first sending power is notified to a specified user terminal in a service area in a specified mode. Therefore, in the spectrum sharing process, the corresponding maximum transmitting power can be configured to the communication equipment of the corresponding type based on the interference environment and the type of the communication equipment, the interference to an out-of-band system is reduced, and the coexistence among multiple systems is realized.
The description is supplemented and refined by two pairs of embodiments one.
Example two
Fig. 2 shows a flowchart of a method of configuring transmission power according to another embodiment of the present invention.
As shown in fig. 2, a method for configuring transmission power according to another embodiment of the present invention includes:
step S201, obtaining interference environment information and a pre-specified terminal type.
The pre-specified terminal type is a standard terminal type pre-stored in the base station, and the standard terminal type may be a certain type of the user terminal in the service area of the base station, or may be all types of the user terminal in the service area of the base station.
For example, the sggp terminal and the 3GPP terminal may be allowed to access the sgxgp base station in the sgxgp system, and the sgxgp base station may pre-select and store the sgxgp standard terminal type and the 3GPP standard terminal type. Therefore, when calculating the first power, the sXGP base station can acquire the sXGP standard terminal type, or acquire the 3GPP standard terminal type, or acquire the sXGP standard terminal type and the 3GPP standard terminal type at the same time.
Step S202, calculating a first transmitting power corresponding to the terminal type according to the interference environment information and a pre-specified terminal type. Wherein the first transmission power is calculated based on a pre-specified terminal type.
That is to say, when the sggp base station acquires the sgxgp standard terminal type, the corresponding first transmission power is a single power calculated based on the sgxgp standard terminal type and the interference environment information; when the type of the 3GPP standard terminal is acquired by the sXGP base station, the corresponding first sending power is a single power calculated based on the type of the 3GPP standard terminal and the interference environment information; when the sXGP base station acquires the sXGP standard terminal type and the 3GPP standard terminal type, the corresponding first transmitting power is calculated based on the sXGP standard terminal type, the 3GPP standard terminal type and the interference environment information respectively.
Step S203, notifying the first transmission power to the appointed user terminal in the service area in a broadcasting mode. Specifically, the sXGP base station informs the appointed user terminals in the service area of the single or two first transmission powers obtained by calculation in a broadcasting mode.
It should be noted that, if the base station receives the ue type reported by the ue, the ue type needs to be determined according to the reported ue information. The method specifically comprises the following modes:
a) when the user terminal information is International Mobile Subscriber Identity (IMSI) information, if the IMSI information carries the designated information of a first terminal, the user terminal type is the first terminal; and if the IMSI information carries the designated information of the second terminal, the type of the user terminal is the second terminal.
Specifically, the IMSI (International Mobile Subscriber identity Number) information is composed of an MCC (Mobile country Code), an MNC (Mobile Network Code), and an MSIN (Mobile Subscriber identity Number). The sXGP system will apply for a new MCC and MNC for the sXGP terminal, which is different from the existing MCC and MNC combination. When the sXGP base station receives the MCC and MNC in the IMSI information reported by the terminal and exists in the code number range of the traditional operator, the type of the terminal is judged to be a 3GPP terminal; and when the sXGP base station receives the MCC and MNC in the IMSI information reported by the terminal and exists in the code number range of the new system, judging that the terminal type is the sXGP terminal.
b) When the user terminal information is international mobile equipment identity code IMEI information, if the IMEI information carries the specified information of a first terminal, the user terminal type is the first terminal; and if the IMEI information carries the specified information of the second terminal, the user terminal type is the second terminal.
Specifically, the IMEI (International Mobile Equipment Identity) is an "electronic serial number" composed of 15 digits, and is a one-to-one correspondence with each terminal as a unique identifier of the terminal. The sXGP base station can determine whether the terminal type is a 3GPP terminal or an sXGP terminal by judging through the IMEI range reported by the terminal.
c) When the user terminal information is wireless access type RAT information, if the RAT information carries the appointed information of a first terminal, the user terminal type is the first terminal; and if the RAT information carries the designated information of the second terminal, the user terminal is of the second terminal type.
Specifically, the sggp system defines a new RAT (Radio Access Type) based on the sggp terminal, and when the sggp base station receives the RAT of the 3GPP terminal, the terminal Type is the 3GPP terminal; when the sXGP base station receives the newly defined RAT, the terminal type is the sXGP terminal.
d) When the user terminal information is standard version number information, if the standard version number information carries the specified information of the first terminal, the user terminal type is the first terminal; and if the standard version number information carries the specified information of the second terminal, the user terminal is of the second terminal type.
Specifically, the sXGP system defines new standard version number information based on the sXGP terminal, and when the sXGP base station receives the standard version number information of the 3GPP terminal, the terminal type is the 3GPP terminal; and when the sXGP base station receives the newly defined standard version number information, the terminal type is the sXGP terminal.
e) When the user terminal information is radio frequency Parameter RF-Parameter information, if the RF-Parameter information carries the specified information of a first terminal, the user terminal type is the first terminal; and if the RF-Parameter information carries the designated information of the second terminal, the user terminal type is the second terminal.
Specifically, the sggp system defines any new RF-Parameter Information based on the sggp terminal, which may specifically be one or more of Band frequency Band Information, EARFCN frequency point Information, an IE (Information Element) defining a field, and multiple IEs defining a field, and when the sggp base station receives one or more of the Band Information, the EARFCN Information, the IE defining a field, and the multiple IEs defining a field of the 3GPP terminal, the terminal type is the 3GPP terminal; and when the sXGP base station receives one or more of newly defined frequency Band information, frequency point EARFCN information, one IE for defining a field and a plurality of IEs for defining the field, the type of the terminal is the sXGP terminal.
f) When the user terminal information is user capability information, if the user capability information carries the specified information of the first terminal, the user terminal type is the first terminal; and if the user capability information carries the designated information of the second terminal, the user terminal type is the second terminal.
Specifically, the user capability information of different types of terminals in the sggp system is different, and the user capability information is any one or two of function Indicator identifier (FGI) information or terminal capability identifier (UE capability Indicator) information. When the sXGP base station receives one or two of FGI information or terminal capability identification information of the 3GPP terminal, the terminal type is the 3GPP terminal; and when the sXGP base station receives one or two of the FGI information or the terminal capability identification information of the sXGP terminal, the terminal is the type of the sXGP terminal.
It should be noted that, in this embodiment, there is no limitation on whether the base station receives the ue information reported by the ue. That is, even if the ue does not report the ue information, or the bs does not perform subsequent processing after receiving the ue information, the power configuration can still be completed. However, if the ue does not report the ue information all the time, after the power configuration is completed, that is, after the ue determines the final maximum transmit power, it needs to report the maximum transmit power to the base station.
According to the technical scheme of the embodiment, firstly, interference environment information and a user terminal type are obtained, then, first sending power corresponding to the user terminal type is calculated according to the interference environment information and the user terminal type, and finally, the first sending power is notified to a specified user terminal in a service area in a specified mode. Therefore, in the spectrum sharing process, the corresponding maximum transmitting power can be configured to the communication equipment of the corresponding type based on the interference environment and the type of the communication equipment, the interference to an out-of-band system is reduced, and the coexistence among multiple systems is realized.
EXAMPLE III
On the basis of the embodiment shown in fig. 1, there may be another implementation way shown in connection with fig. 3.
As shown in fig. 3, includes:
step S301, receiving the user terminal information reported by the appointed user terminal, and determining the user terminal type according to the user terminal information.
It should be noted that there are various ways for the base station to determine the type of the ue through the reported ue information, and the specific implementation is the same as the implementation described in the second embodiment, and therefore, the details are not repeated here.
Step S302, interference environment information is acquired.
It should be noted that, step 301 and step 302 are not sequentially executed, so the present embodiment is not limited in this embodiment, step 301 may be executed before step 302, or may be executed after step 302, or both may be executed simultaneously, which does not limit the protection scope of the present invention.
Step S303, grouping each of the ues according to the ue type.
Step S304 is to notify the first transmission power corresponding to each ue group to the designated ue in the service area in a multicast or unicast manner.
For example, when the interference value detected by the sggp base station is-82 dBm, it means that the base station is far away from other systems, and therefore the probability of interference to other systems is small, and the maximum transmission power of the 3GPP terminal is set to be 20dBm and the maximum transmission power of the sggp terminal is set to be 23 dBm. If the interference value detected by the base station is-72 dBm, the base station is close to other systems, and the probability of interference to other systems is high, the maximum transmission power of the 3GPP terminal is set to be 10dBm, and the maximum transmission power of the sggp terminal is set to be 13 dBm. The sXGP base station groups each user terminal according to the user terminal type, for example, a plurality of 3GPP terminals are grouped into a group, a plurality of sXGP terminals are grouped into a group, then the maximum transmission power of 10dBm is notified to the 3GPP terminal group in a multicast or unicast mode, and simultaneously the maximum transmission power of 13dBm is notified to the sXGP terminals in the multicast or unicast mode.

Example four
On the basis of the first embodiment, the second embodiment and the third embodiment, the present embodiment provides a method for configuring a transmit power based on a terminal.
As shown in fig. 4, the method for configuring transmit power according to this embodiment includes:
step S401 receives the first transmission power notified by the base station.
In this embodiment, the sggp system includes an sgxgp base station, a 3GPP user terminal, and an sgxgp user terminal, where the 3GPP user terminal receives a first transmission power corresponding to a type based on a preset 3GPP user terminal notified by the base station, or receives a first transmission power corresponding to a type based on a preset sgxgp user terminal, or receives two first transmission powers corresponding to a type based on a preset 3GPP user terminal and a type of a preset sgxgp user terminal; correspondingly, the sggp ue receives the first transmit power corresponding to the type of the preset 3 GPP-based ue notified by the base station, or receives the first transmit power corresponding to the type of the preset sggp ue, or receives two first transmit powers corresponding to the type of the preset 3 GPP-based ue and the type of the preset sggp ue.
Step S402, according to the first sending power and the user terminal type, determining a second sending power.
When determining the second transmission power, the terminal specifically has the following two modes:
a) when the first transmission power is single,
and when the first transmission power is matched with the type of the user terminal, taking the first transmission power as a second transmission power.
When the first transmission power is single,
and when the first sending power is not matched with the type of the user terminal, processing to obtain a second sending power based on a preset processing strategy and the first sending power.
For example, the maximum transmission power calculated by the sggp base station according to the preset 3GPP standard terminal is 10dBm, and the sggp base station notifies the specified user terminal, and the 3GPP user terminal adopts 10dBm as the maximum transmission power, because the out-of-band radiation index of the sggp user terminal is better than that of the 3GPP terminal, the maximum transmission power of the sggp user terminal is adjusted by the preset processing policy, for example, the maximum transmission power of the sggp user terminal is adjusted to 13 dBm.
b) When the first transmission power is multiple, determining a second transmission power according to the first transmission power and the user terminal type, which specifically includes:
and matching corresponding first transmission power from each first transmission power according to the type of the user terminal, and taking the corresponding first transmission power as second transmission power.
For example, the maximum transmission power calculated by the sggp base station according to the preset 3GPP standard terminal and the sggp standard is 10dBm and 13dBm, respectively, and the sggp base station notifies the designated user terminal, and after the 3GPP user terminal receives the maximum transmission power of 10dBm and 13dBm, 10dBm is selected as the maximum transmission power; the sXGP user terminal selects 13dBm as the maximum transmission power after receiving the maximum transmission power of 10dBm and 13 dBm.
It should be noted that the method further includes: and the base station reports the user terminal information.
Specifically, the user terminal information is any one or more of international mobile subscriber identity IMSI information, international mobile equipment identity IMEI information, radio access type RAT information, standard version number information, radio frequency Parameter RF-Parameter information, and user capability information. The RF-Parameter information is any one or more of frequency band information, frequency point information, an information element for defining a field and a plurality of information elements for defining the field; the user capability information is function indication identification (FGI) information or terminal capability identification information.
In addition, if the terminal does not report the ue information in the whole power configuration process, the terminal needs to send the second sending power to the base station.
