Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
In order to meet the development requirement of communication technology, 5G, as an emerging communication technology, can be regarded as a reengineering after LTE, that is, a New technology with innovation introduced at the same time for evolution, such as a New Radio communication (NR) technology of 5G, also referred to as a 5G New air interface technology. Currently, the Third Generation Partnership Project (3 GPP) defines two networking modes for the 5G NR technology, namely non-independent networking and independent networking. The non-independent networking refers to that a control plane (4G carries control signaling) is independently deployed by 4G, a user plane (5G and 4G carry user plane data) is jointly deployed by 5G and 4G, or a user plane (only 5G carries user plane data) is independently deployed by 5G (that is, dual connectivity meeting LTE and NR is needed in an NSA mode to realize communication; independent networking refers to independent networking in which a control plane and a user plane are independently deployed by 5G (5G independently carries control signaling and user plane data), and based on a 5G new air interface technology, at this time, 5G may not depend on 4G to work, but transmission of a dual Transmitter (Transmitter, TX) is required in an SA mode.
Referring to fig. 1, a schematic diagram of a constituent structure of a wireless communication system 10 according to an embodiment of the present application is shown. The wireless communication system 10 is not limited to a wireless communication system supporting an LTE network, and may be a wireless communication system supporting a 4G network, a wireless communication system supporting a 5G network or a 5G NR technology, or the like. As shown in fig. 1, a wireless communication system 10 may include a terminal 101 and a base station 102. In this wireless communication system, a terminal 101 and a base station 102 can communicate through a wireless network; specifically, the terminal 101 may transmit uplink data to the base station 102 through the wireless network, and the base station 102 may also transmit downlink data to the terminal 101 through the wireless network. Here, the wireless network may include an LTE network, a 4G network, a 5G network, and the like.
Generally, the terminals 101 are distributed throughout the wireless communication system and may be stationary or mobile. In the embodiment of the present application, the terminal 101 may be a user equipment supporting a 4G network and/or a 5G network, including but not limited to a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a navigation device, a Portable Media Player (PMP), a wearable device, and the like, or a fixed terminal such as a Digital television, a desktop computer, and the like; in addition, the base station 102 may be a base station in an LTE network or a 4G network, may also be a base station in a 5G network, and may even be an Access Point (AP) or other network entities, and the like, which is not specifically limited in this embodiment of the application.
Aiming at two networking modes, namely non-independent networking and independent networking, the related technical scheme provides two hardware architecture examples of the terminal; one is to separate the 4G and 5G modems (modems) separately, and the other is to combine the 4G and 5G modems (the multimode modems can even combine the 2G/3G/4G/5G). Which will be described separately below.
Referring to fig. 2, a schematic diagram of a structure of a terminal hardware architecture provided in the related art is shown. As shown in fig. 2, the terminal 20 may include an Application Processor (AP) 201, a 4G Modem (4G Modem)202, a 5G Modem (5G Modem)203, a first Primary set receiving (1st Primary Receiver, PRX1) module 204, a first Diversity receiving (1st Diversity Receiver, DRX1) module 205, a first Multiple-Input Multiple-Output (1st Multiple-Input Multiple-Output, MIMO1) module 206, a second Multiple-Input Multiple-Output (2nd Multiple-Input Multiple-Output, MIMO2) module 207, a first antenna 208, a second antenna 209, a third antenna 210, a fourth antenna 211, a second Primary set receiving (2nd Multiple-Input Receiver, MIMO2) module 212, a second Diversity receiving (2nd Multiple-Input Multiple-Output, DRX 593 nd Multiple-Output (DRX) module 214, MIMO4) module 215, fifth antenna 216, sixth antenna 217, seventh antenna 218, eighth antenna 219, and so on.
In fig. 2, the terminals 20 are each separately divided into a 4G Modem 202 and a 5G Modem 203; that is, the 5G Modem 203 is connected to the PRX1 module 204, the DRX1 module 205, the MIMO1 module 206 and the MIMO2 module 207, and then transmits a signal to an external network (e.g., a base station) through a set of antennas (including the first antenna 208, the second antenna 209, the third antenna 210 and the fourth antenna 211); the 4G Modem 202 is connected to the PRX2 module 212, the DRX2 module 213, the MIMO3 module 214, and the MIMO4 module 215, and then transmits signals to an external network (e.g., a base station) through a set of antennas (including the fifth antenna 216, the sixth antenna 217, the seventh antenna 218, and the eighth antenna 219). Thus, the two modems separated from each other will make the 4G and 5G dual modems operate in the NSA state, which results in large power consumption of the terminal.
Referring to fig. 3, a schematic diagram of a structure of another terminal hardware architecture provided in the related art is shown. As shown in fig. 3, the terminal 20 may further include a multimode Modem (multimode Modem)301, a first Power Amplifier (PA 1)302, a second Power Amplifier (2nd Power Amplifier, PA2)303, and a switch 304, in addition to the application processor 201, the first antenna 208, the second antenna 209, the third antenna 210, and the fourth antenna 211.
In FIG. 3, the multi-mode Modem may also be referred to as a 5G Modem, which integrates Modem functions of 2G/3G/4G/5G, etc. The multimode Modem 301 is connected to a PA 1302 and a PA 2303 simultaneously, wherein the PA 1302 is used for amplifying a first transmission signal TX1, and the PA 2303 is used for amplifying a second transmission signal TX 2; the switch 304 is used to switch signals on TX1 or TX2 among different antennas, such as the first antenna 208, the second antenna 209, the third antenna 210, and the fourth antenna 211, so as to transmit signals to an external network (such as a base station). Thus, the integrated multimode Modem can cause the dual TX transmission in the SA state to cause large power consumption of the terminal; in addition, large wideband, high order modulation under the 5G new standard also results in a cumulative increase in power consumption.
For 5G networks, whether independent networking or non-independent networking, the current solutions cause the power consumption of the terminal to be too high, thereby reducing the system performance of the terminal. Based on this, the embodiment of the present application provides a communication control method, by transmitting a sounding reference signal to a base station; receiving a return value fed back by the base station; wherein the feedback value is obtained by the base station according to the received sounding reference signal; controlling the terminal to communicate with the base station according to target transmitting information by analyzing the return value; the target transmission information represents transmission information with optimal power consumption in the communication process of the terminal and the base station; therefore, based on the SRS mechanism, the maximum optimization of power consumption in the process of establishing connection between the terminal and the base station is realized, and the terminal communicates with the base station according to the transmitting information with the optimal power consumption, so that the power consumption of the terminal is effectively reduced, the system performance of the terminal is improved, and the user experience is also improved.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 4, a flowchart of a communication control method provided in an embodiment of the present application is shown. As shown in fig. 4, the method may include:
s401: transmitting a sounding reference signal to a base station;
it should be noted that the method is applied to a terminal, and the terminal can support the communication function of the 5G network, so the terminal can also be referred to as a 5G terminal. In addition, the sounding reference signal is also referred to as SRS, and is an uplink signal transmitted from the terminal to the base station, and the base station may estimate uplink channel quality of different frequency bands by using the SRS, and may also estimate downlink channel quality by using channel symmetry.
For a 5G network, two networking modes are defined, namely independent networking and non-independent networking. Under the non-independent networking, a 4G network and a 5G network are combined to form a network, and the SRS can be sent to the base station only by meeting the dual-connection of LTE and NR; under the independent networking, the 5G network is independently deployed, and the 5G network can send the SRS to the base station without depending on the 4G network. However, it should be noted that under independent networking, dual TX transmission signals are required. The following description will be made in detail by taking independent networking as an example.
For example, refer to fig. 5, which shows a schematic structural diagram of a dual TX transmit signal provided in an embodiment of the present application. As shown in fig. 5, (a) provides a structural example of a TX1 transmit signal, and (b) provides a structural example of a TX2 transmit signal, where TX1 and TX2 constitute a dual TX transmit signal. For the SA state of independent networking, dual-TX SRS transmission is performed based on a Sounding Reference Signal Switching (SRS Switching) mechanism. For the 4 transmission paths formed by the first antenna 208, the second antenna 209, the third antenna 210, the fourth antenna 211, and the like, each TX in the dual TX needs to transmit an SRS signal on the four transmission paths, and the process is performed in the same cycle, that is, in one cycle, there are 4 time periods of dual TX signals, as shown in fig. 6, which is a schematic diagram of dual TX signals coexisting in the same cycle. In fig. 6, a first sounding reference signal (which may be denoted by SRS 1) is transmitted on the transmission path formed by the first antenna 208, a second sounding reference signal (which may be denoted by SRS 2) is transmitted on the transmission path formed by the second antenna 209, a third sounding reference signal (which may be denoted by SRS 3) is transmitted on the transmission path formed by the third antenna 210, and a fourth sounding reference signal (which may be denoted by SRS 4) is transmitted on the transmission path formed by the fourth antenna 211; in addition, T1 is a period of transmission on the transmission path formed by the first antenna 208, T2 is a period of transmission on the transmission path formed by the second antenna 209, T3 is a period of transmission on the transmission path formed by the third antenna 210, T4 is a period of transmission on the transmission path formed by the fourth antenna 211, and T1, T2, T3, and T4 are 4 periods in the same cycle; thus, as can be seen from fig. 6, in the same period, T1 time period, SRS1 will be present in the dual TX (TX1 and TX2) signals; the T2 time period, SRS2 would be present in the dual TX (TX1 and TX2) signals; the T3 time period, SRS3 would be present in the dual TX (TX1 and TX2) signals; the T4 time period, SRS4 would be present in the dual TX (TX1 and TX2) signals; that is, in the SA state for independent networking, SRS transmission from the terminal to the base station is signaled in accordance with dual TX.
Therefore, before sending data to the base station, the terminal sends the SRS to the base station to realize the communication connection between the terminal and the base station according to the SRS, so that the power consumption optimization in the process of establishing the connection between the terminal and the base station can be realized.
S402: receiving a return value fed back by the base station; wherein the feedback value is obtained by the base station according to the received sounding reference signal;
it should be noted that the report value is obtained by the base station according to the received SRS, and may reflect the signal reception strength corresponding to the SRS. Thus, after the base station determines the return value corresponding to the SRS, the base station feeds back the return value to the terminal; based on the response of the terminal to the reported value, the communication connection between the terminal and the base station can be completed.
S403: controlling the terminal to communicate with the base station according to target transmitting information by analyzing the return value; the target transmission information represents transmission information with optimal power consumption in the communication process of the terminal and the base station.
It should be noted that, after the terminal receives the return value, the terminal may analyze the return value to determine the distance between the terminal and the base station, so as to select the transmission information with the optimal power consumption, and according to the transmission information with the optimal power consumption, the communication between the terminal and the base station may be implemented. Therefore, in some embodiments, for S403, the controlling the terminal to communicate with the base station according to the target transmission information by analyzing the report value may include:
s403 a: analyzing the return value to obtain a distance value between the terminal and the base station;
it should be noted that the return value may reflect the signal reception strength corresponding to the SRS, so that the terminal may determine the distance value between the terminal and the base station through analysis of the return value, so as to further determine the target transmission information corresponding to the terminal.
S403 b: obtaining target transmitting information corresponding to the terminal according to the distance value, and controlling the terminal to communicate with the base station according to the target transmitting information;
it should be noted that the terminal may establish a corresponding relationship between the distance value and the transmission information according to a large amount of test data at an earlier stage, and store the corresponding relationship. The corresponding relation can be stored in a memory in the terminal or in a network server, and the terminal accesses the network server to obtain the corresponding relation; the embodiments of the present application are not particularly limited.
Further, in some embodiments, for S403b, before obtaining the target transmission information corresponding to the terminal according to the distance value, the method may further include:
acquiring a corresponding relation between a pre-stored distance value and transmission information;
correspondingly, the obtaining target emission information corresponding to the terminal according to the distance value may include:
and inquiring the transmitting information corresponding to the distance value from the acquired corresponding relation between the distance value and the transmitting information according to the distance value to obtain the target transmitting information.
That is, after the terminal acquires the correspondence between the pre-stored distance value and the transmission information, the transmission information corresponding to the distance value can be selected by querying from the correspondence between the distance value and the transmission information according to the acquired distance value, and the selected transmission information is used as the target transmission information corresponding to the terminal.
Thus, after obtaining the distance value, the terminal may select the transmission information corresponding to the distance value according to the corresponding relationship between the distance value and the transmission information, so as to serve as the target transmission information, and then control the terminal to communicate with the base station according to the target transmission information.
In the embodiment of the application, the target transmitting information is transmitting information with optimal power consumption in the communication process of the terminal and the base station; wherein the transmission information may include at least a transmission signal strength and a transmission signal stream number. Thus, for independent networking, since dual TX transmit signals (such as TX1 and TX2) are required, that is, the number of transmit signal streams in the target transmit information is equal to 2, and the transmit signal strength includes the transmit signal strength of TX1 and the transmit signal strength of TX 2; in addition, the strength of the transmission signal of TX1 may be the same as or different from that of TX2, and in practical application, the strength is set according to practical situations, and the embodiment of the present application is not particularly limited.
Further, in some embodiments, for S403, the controlling the terminal to communicate with the base station according to the target transmission information may include:
performing information configuration on at least one transmitting signal of the terminal according to the target transmitting information;
communicating with the base station based on the at least one transmitted signal.
It should be noted that, for non-independent networking, only one transmission signal may be needed to communicate with the base station; thus, the information configuration is carried out on the transmitting signal according to the target transmitting information, and then the communication is carried out with the base station according to the configured transmitting signal; for independent networking, dual-TX transmission is needed, and at this time, two transmission signals are needed to communicate with a base station; thus, the two transmitting signals are subjected to information configuration according to the target transmitting information, and then the two transmitting signals after configuration are communicated with the base station; because the information configuration is carried out on at least one transmitting signal of the terminal, the terminal can communicate with the base station according to at least one transmitting signal with the optimal power consumption, and the power consumption optimization of the terminal is realized.
Further, in some embodiments, for S402, after receiving the reward value fed back by the base station, the method may further include:
and completing the communication connection with the base station based on the response to the report value.
That is, after the terminal receives the reported back value fed back by the base station, the communication connection between the terminal and the base station is completed according to the response of the terminal to the reported back value.
Compared with the current solution, because in the current solution, the terminal firstly needs to transmit a signal according to the maximum power to search the response of the base station, after the response of the base station, the connection between the terminal and the base station is realized; then, the optimal power consumption selection corresponding to the terminal is realized through closed-loop power control, and finally, communication is carried out with the base station according to the transmitting signal with the optimal power consumption; therefore, the power consumption of the terminal is high, the system performance of the terminal is reduced, and the user experience is poor; in the embodiment of the present application, the terminal first transmits the SRS to the base station, the base station feeds back a report value (which may also be referred to as SRS signal reception strength) corresponding to the SRS, and based on a response of the terminal to the report value, the communication connection between the terminal and the base station can be completed; then the terminal judges the distance value between the terminal and the base station according to the return value fed back by the base station, and can select the TX signal intensity and the TX signal flow number corresponding to the distance value so as to realize power consumption optimization; therefore, based on the SRS mechanism, on one hand, the maximum optimization of power consumption in the process of establishing connection between the terminal and the base station can be effectively improved for the connection between the terminal and the base station; on the other hand, according to the selected TX signal intensity and the selected TX signal flow number, the terminal can communicate with the base station according to the transmitting information with the optimal power consumption, so that the power consumption of the terminal is effectively reduced, and the user experience is improved.
In another embodiment of the present application, two networking modes are defined for the 5G network, which are independent networking and non-independent networking respectively. Therefore, in some embodiments, refer to fig. 7, which shows a flowchart of another communication control method provided in the embodiments of the present application. As shown in fig. 7, before S401, the method may further include:
s701: determining a supported networking mode; the networking mode comprises non-independent networking and independent networking;
s702: when the supported networking mode is independent networking, the step of transmitting the sounding reference signal to the base station is executed based on a 5G network signal;
s703: and when the supported networking mode is non-independent networking, acquiring 5G network coverage through a 4G network, and executing the step of transmitting the sounding reference signal to the base station based on a 5G network signal.
Further, in some embodiments, for S703, when the supported networking manner is non-independent networking, the terminal is registered in the 4G network and is in a coverage area of the 5G network.
It should be noted that, after step S701, after determining the networking mode supported by the current terminal, if the supported networking mode is independent networking, step S702 is executed; if the supported networking mode is dependent networking, step S703 is executed.
It should be noted that, before the terminal transmits the SRS to the base station, it is also necessary to first determine the networking mode supported by the terminal. Here, the determining of the networking mode supported by the terminal may be performed by the terminal itself or by the base station, and this embodiment of the present application is not specifically limited.
Thus, after the networking mode supported by the terminal is determined, if the supported networking mode is independent networking, the terminal is registered in the 5G network, so that the step of S401 can be directly executed based on the 5G network signal; if the supported networking mode is non-independent networking, because the terminal is registered in the 4G network, when the terminal is in the 5G network coverage area, the terminal can acquire the 5G network coverage through the 4G network, so that the step of S401 is executed based on the 5G network signal.
For example, refer to fig. 8, which illustrates a detailed flowchart of a communication control method provided in an embodiment of the present application. As shown in fig. 8, the method is still applied to the terminal, and the method may include:
s801: the terminal is registered in the 4G network;
s802: the terminal enters a 5G network coverage area;
s803: the terminal acquires 5G network coverage through a 4G network;
s804: based on the 5G network signal, the terminal transmits a 5G SRS to the base station;
s805: the terminal receives a return value fed back by the base station; wherein the report value is obtained by the base station according to the received 5G SRS;
s806: analyzing the return value to obtain a distance value between the terminal and the base station;
s807: the control terminal communicates with the base station according to the target transmitting information; and the target transmission information represents transmission information with optimal power consumption in the communication process of the terminal and the base station.
It should be noted that the present embodiment is applied to the NSA state of the non-independent networking; compared with the SA state of independent networking, the method has the main difference that the terminal is registered in the 4G network, and then the 5G network coverage corresponding to the terminal is obtained through the 4G network, so that the communication between the terminal and the base station is realized based on the 4G network and the 5G network. Therefore, based on the SRS mechanism, under the NSA state of the non-independent networking, the maximum optimization of the power consumption in the connection process between the terminal and the base station can be realized, and the terminal can communicate with the base station according to the transmitting information with the optimal power consumption, so that the power consumption of the terminal is effectively reduced, and the user experience is improved.

s901: receiving a sounding reference signal transmitted by a terminal;
it should be noted that the method is applied to a base station. The sounding reference signal is also referred to as SRS, and is an uplink signal transmitted from the terminal to the base station, and after receiving the SRS, the base station may estimate uplink channel quality of different frequency bands using the SRS, and may also estimate downlink channel quality using channel symmetry.
S902: determining a report value corresponding to the sounding reference signal according to the received sounding reference signal;
it should be noted that the report value is obtained by the base station according to the received SRS, and may reflect the signal reception strength corresponding to the SRS. Thus, after receiving the SRS, the base station can determine a report value corresponding to the SRS. For SRS, the terminal transmits SRS to the base station, and the base station evaluates the transmission signal level according to the received SRS, so that the base station can feedback the signal reception strength to the terminal according to the received SRS, for example, the signal reception strength is represented by a report value, which may also be referred to as an acknowledgement value.
S903: sending the report value to a terminal to control the terminal to communicate with the base station according to target transmitting information; the target transmission information represents transmission information with optimal power consumption in the communication process of the terminal and the base station.
It should be noted that, after determining the reported value, the base station may feed back the reported value to the terminal; therefore, after the terminal receives the return value, the terminal can analyze the return value to determine the distance between the terminal and the base station, so that the transmitting information with optimal power consumption can be selected, the terminal can communicate with the base station according to the target transmitting information, and the power consumption of the terminal is optimized.
Further, in some embodiments, for S903, after the sending the report value to the terminal, the method may further include:
and completing the communication connection with the terminal based on the response of the terminal to the return value.

Therefore, based on the SRS mechanism, the terminal transmits the SRS to the base station, and the base station feeds back the report value to the terminal according to the SRS to realize the connection between the terminal and the base station, so that the maximum optimization of the power consumption of the terminal and the base station in the connection establishment process can be effectively improved.
It should be further noted that, as the 5G network defines two networking modes, which are independent networking and non-independent networking respectively. That is, the embodiments of the present application may be applied to independent networking and may also be applied to non-independent networking; for non-independent networking, the terminal needs to acquire corresponding 5G network coverage through the 4G network in a state of being registered in the 4G network, so that communication between the terminal and the base station is realized based on the 4G network and the 5G network together.
