The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
The following detailed description of embodiments of the present disclosure refers to the accompanying drawings.
Fig. 1 shows a schematic diagram of an exemplary system architecture of a cell power saving method or cell power saving device that may be applied to embodiments of the present disclosure.
As shown in fig. 1, the system architecture may include a base station 101 and a terminal 102.
Base station 101 may be a 5G or later version of a base station (e.g., 5G NR NB, 6G) or a base station in other communication systems (e.g., eNB base station), although the specific type of base station 101 is not limited in the embodiments of the present disclosure.
The terminal 102 may be a variety of electronic devices including, but not limited to, smartphones, tablets, laptop portable computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, and the like.
Alternatively, the clients of the applications installed in different terminals 102 are the same or clients of the same type of application based on different operating systems. The specific form of the application client may also be different based on the different terminal platforms, for example, the application client may be a mobile phone client, a PC client, etc.
The base station 101 and the terminal 102 are connected via a network, which may be a wired network or a wireless network.
Alternatively, the wireless network or wired network described above uses standard communication techniques and/or protocols. The network is typically the Internet, but may be any network including, but not limited to, a local area network (Local Area Network, LAN), metropolitan area network (Metropolitan Area Network, MAN), wide area network (Wide Area Network, WAN), mobile, wired or wireless network, private network, or any combination of virtual private networks. In some embodiments, data exchanged over a network is represented using techniques and/or formats including HyperText Mark-up Language (HTML), extensible markup Language (Extensible MarkupLanguage, XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as secure sockets layer (Secure Socket Layer, SSL), transport layer security (Transport Layer Security, TLS), virtual private network (Virtual Private Network, VPN), internet protocol security (Internet ProtocolSecurity, IPsec), etc. In other embodiments, custom and/or dedicated data communication techniques may also be used in place of or in addition to the data communication techniques described above.

The base station does not need to transmit random access response (Random Access Response, RAR) when receiving the sensing signal sequence, thereby further saving electric energy. In addition, the terminal does not need to enter the RRC connection state, so that the electric energy of the terminal is saved.
In the embodiment of the disclosure, a cell energy saving method is provided, when the utilization rate of physical resource blocks (Physical Resource Block, PRBs) meets a preset sensing signal generation condition, a base station 101 sends configuration parameters of a sensing signal to a terminal 102, the terminal 102 receives the configuration parameters and generates a sensing signal sequence according to the configuration parameters, the terminal 102 sends the sensing signal sequence to the base station 101, and the base station 101 determines an energy saving strategy of a cell according to the received sensing signal sequence.

In addition, the terminal 102 to be served can transmit the sensing signal sequence without entering an RRC (radio resource control) connected state, thereby further saving the electric energy of the base station 101.
In some embodiments, the cell power saving method provided in the embodiments of the present disclosure may be performed in the base station 101 shown in fig. 1.

s403, the terminal sends the sensing signal sequence to the base station;
s404, the base station determines the energy saving strategy of the cell according to the sensing signal sequence.
For example, the base station counts the average utilization rate of PRB resources in a period T of time, and if the average utilization rate is lower than a threshold X of the average utilization rate, determines that a configuration parameter of a sensing signal needs to be issued, for example, takes 1 hour, and the threshold X is set to 30%. It should be noted that if the base station does not issue the parameter configuration of the sensing signal, the terminal does not generate and send the sensing signal; the thresholds X and T may be preset on the base station, and the values of the thresholds X and T may be set as needed.
The configuration parameters of the sensing signal comprise a period parameter t and a sensing configuration parameter N s ；
When the terminal receives the configuration parameters of the sensing signals, whether the screen is in a display state or not needs to be judged, and if the screen is in a screen-off state, the sensing signals are not generated and sent;
if the terminal is in the bright screen state, the terminal will generate a sensing signal sequence, such as N, according to the value (sensing configuration parameter) in the sensing Config of the minimum system information SIB1 s 28;
the generation process of the sensing signal sequence is as follows:
The sensing signal sequence is generated according to the cyclic shift value and the Zaddof-Chu (ZC) sequence, and the sensing signal sequence x u，y (n) is expressed as:
x u，y (n)＝x u (i)((n+C y )modL)
wherein C is y Representing cyclic shift value, x u (i) Represents a zaddif-Chu (ZC) sequence, n=i;
when the value of L is 839, the logical root index is configured to be 20, corresponding to u=2, and the next root index corresponds to u=837;
ZC sequence isWherein L is the length of ZC sequence, uObtained in the rach_root_sequence logical ROOT index table, i=0, 1 …, L-1, j is an imaginary number;
the cyclic shift value is represented by equation C y ＝y×N s Obtained, wherein y=0, 2,4 …, L/N s Taking down even number, L is the length of ZC sequence, L is 839, N s To perceive configuration parameters, N s Has a value of 28.
The ZC sequence of u=2 is as follows:
the cyclic shift values are as follows:
C y =0, 28, 56, … 784, y=0, 2, …, 839/28 rounded to 15 cyclic shifts;
perceptual signal sequence x u，y (n) is as follows:
x 2，0 (n)＝x 2 (n)；
…；
x 2，28 (n) generating 15 ZC sequences with a root sequence of u=2;
x 837，0 (n) with root sequence of u=837, 15 ZC sequences are generated;
… continues with the next root sequence until a total of 64 ZC sequences are generated.
The terminal will also transmit the sensing signal sequence according to the periodic parameter t of the sendperiod configuration parameter, for example, t=60 s;
For the reception of the sensing signal sequence, the base station does not transmit RAR when receiving the sensing signal sequence, thereby saving electric energy.
The number of terminals which do not need to be served is obtained by subtracting the number of terminals (terminals to be served) sending a sensing signal sequence from the number of all terminals in a service cell of a base station; the arrival angle information, the signal strength information, which ssb (broadcast beam) sends information and the like can be obtained by detecting the sensing signal sequence, so that the position information and the quantity information of the terminal to be served, including the terminal in use by the user or the terminal possibly used by the user, can be determined according to the sensing signal sequence, the position information of the terminal which is not needed to be served is obtained, and the base station performs proper energy-saving method selection, such as channel closing, symbol closing, carrier frequency closing, deep dormancy and the like, according to the quantity and the position information of the terminal which are not needed to be served.
