Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Please refer to fig. 1a and 1b, which are schematic diagrams of an implementation scenario provided in the embodiment of the present application. The network equipment transmits signals, and the terminal scans the signals transmitted by the network equipment and accesses uplink resources corresponding to the signals so as to carry out communication.
As shown in fig. 1a, the network device includes a first base station 200 and a second base station 300, the terminal includes a UE100, and a current location of the UE100 is covered by a plurality of cells, where the cell covered by the first base station 200 is a first cell and the cell covered by the second base station 300 is a second cell. The terminal 100 is located in an intersection of a first cell and a second cell. It can be understood that the signal quality of the cell covered by the first base station 200 scanned by the UE100 is stronger than the signal quality of the cell covered by the second base station 300.
Of course, the second cell may comprise more than one, and the second cell may comprise other cells covered by the first base station 100 (as shown in fig. 1 b), may also comprise other cells covered by the second base station 200, or may comprise cells covered by other second base stations. That is, one base station may cover a plurality of cells. For the case shown in fig. 1b, it can be understood that, among the cells covered by the first base station, the cell with the strongest signal quality is the first cell, and the rest are the second cells. Meanwhile, one cell may cover multiple terminals, such as a first cell covering UE1 and UE2, and a second, smaller covering UE 3.
The cell covered by the current location of the UE may include a cell of a fifth Generation Mobile communication (5th Generation Wireless System new Radio, 5G NR) System, a cell of a Long Term Evolution (LTE) System, a cell of a Universal Mobile Telecommunications System (UMTS) System, a cell of a Global System for Mobile Communications (GSM) System, or a combination thereof. And for the 5G NR system cell, the LTE system cell, the UMTS system cell and the GSM system cell, a plurality of cells are respectively included.
Each cell (the first cell and the second cell) corresponds to a frequency point (or a frequency band). The frequency point is a central frequency point. For example, the central frequency point is 2100MHz, the system bandwidth is 20MHz, and then the frequency band of this cell is 2090-2110 MHz.
The adjacent cell may be concentric with the cell, or may be different. If the frequency point is the concentric frequency point, for LTE, an inter-cell interference coordination technology is used for controlling the inter-cell interference at the edge. If the frequency is different, the difference between the central frequency points is at least 20Mhz, and the frequency does not overlap.
The terminal includes but is not limited to: personal computers, tablet computers, handheld devices, in-vehicle devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and the like. Terminals can be called different names in different networks, for example: user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, terminal, wireless communication device, user agent or user equipment, cellular telephone, cordless telephone, Personal Digital Assistant (PDA), terminal equipment in a 5G NR network or future evolution network, and the like.
The first base station 200 and the second base station 300 correspond to a Public Land Mobile Network (PLMN) or an operator identity (PLMN), respectively. For base stations of different PLMNs, corresponding frequency bands are different for cells of the same system. For example, the frequency range of the LTE cell corresponding to the PLMN for the china mobile includes 1880-1900MHz (20M), 2320-2370MHz (50M), 2575-2635MHz (65M); the frequency range of the LTE cell corresponding to the PLMN for chinese communication includes 2300-; the frequency range of the LTE cell corresponding to the PLMN in China telecom includes 2370-2390MHz (20M), 2635-2655MHz (20M).
It should be noted that, taking the first cell and the second cell as the 5G NR standard cells as an example, the communication process between the network device and the terminal is described.
As shown in fig. 2, the network device forms a plurality of transmission beams or reception beams, such as 0, 1, 2, …, 7, by beamforming techniques, such as digital beamforming or analog beamforming, and periodically (e.g., every 10ms) transmits or receives. The angle covered by each beam may be the same or different, and there may be overlapping portions between beams with different coverage angles, for example, a network device may transmit control information using a beam with a wider coverage angle and transmit data information using a beam with a narrower coverage angle. The terminal may receive information transmitted by the network device within the coverage of one or more beams or sets or groups of beams therein.
The terminal may also form multiple receive beams through beamforming techniques, and determine to use one or more receive beams for reception corresponding to the downlink beams used by the network device. For convenience of description, the beams referred to in the embodiments of the present application may refer to a single or a plurality of beams.
Accordingly, a downlink transmission beam of a network device and a corresponding reception beam of a user device, or an uplink transmission beam of a user device and a corresponding reception beam of a network device, may be referred to as a pair of beam pairs, and a transmission link formed by the beam pair is referred to as a beam pair link. When the beam of the network device or the user equipment conforms to the beam correspondence characteristic, the corresponding reception beam may be determined from the transmission beam or the corresponding transmission beam may be determined from the reception beam.

The power adjustment method provided by the embodiment of the present application will be described in detail below with reference to fig. 3 to 5. The method may be implemented in dependence on a computer program, operable on a von neumann based power regulating device. The computer program may be integrated into the application or may run as a separate tool-like application. The power adjusting apparatus in the embodiment of the present application may be a network device shown in fig. 1a and 1 b.
Please refer to fig. 3, which is a flowchart illustrating a power adjustment method according to an embodiment of the present disclosure. As shown in fig. 3, the method of the embodiment of the present application may include the steps of:
s101, in the current time period, determining the number of first terminals served by uplink resources associated with a target synchronization signal block, wherein the target synchronization signal block is any synchronization signal block in a synchronization signal block set transmitted by the network equipment;
it will be appreciated that a time period is preset by which the network device transmits a set of synchronization signal blocks. The synchronization signal block set includes at least one synchronization signal block, each synchronization signal block corresponds to a different beam direction (i.e., a transmission signal direction or a reception signal direction), and uplink resources associated with each synchronization signal block are different, so that the number of terminals that can be served is also different.
The uplink resource is a Physical Random Access Channel (PRACH) resource. The PRACH is an Access Channel when a terminal UE starts to initiate a call, and after receiving a Fast Physical Access Channel (FPACH) response message, the UE sends an RRC Connection Request message on the PRACH Channel according to information indicated by the Node B to establish an RRC Connection, so as to Access to a network device, and the network device sends a TPC and an SS to adjust a transmission power and a synchronization offset of the UE.
The Synchronization Signal block is a Synchronization Signal and PBCH (Synchronization Signal and PBCH block, SSB) block, and is composed of a PrimARy Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a PBCH.
The SSB occupies 4 OFDM symbols in the time domain, and the frequency domain occupies 240 subcarriers (20 PRBs) with the number of 0 to 239, as shown in fig. 4.
Wherein the PSS is located at the middle 127 subcarriers of symbol 0.
SSS is located in the middle 127 subcarriers of symbol 2; in order to protect PSS and SSS, there are different subcarriers Set 0 at both ends.
PBCH is located in symbols 1, 3 and symbol 2, where symbols 1 and 3 occupy all subcarriers from 0 to 239, and symbol 2 occupies all subcarriers except subcarriers occupied by SSS and subcarriers Set 0 protecting SSS.
The DM-RS is located in the middle of PBCH, 60 on each symbol, spaced by 4 subcarriers, on symbols 1 and 3.
Wherein PSS, SSS, PBCH and DM-RS thereof occupy different symbols.
The terminal scans the synchronous signal block transmitted by the network equipment, selects the uplink PRACH resource carried by the detected strongest signal SSB, and performs random access on the uplink PRACH resource.
It can be understood that each synchronization signal block may cover multiple cells, the frequency band of each cell may be different, and a terminal accesses a cell corresponding to a synchronization signal block in a certain direction, that is, a cell accessing a certain frequency band in the synchronization signal block. For the accessed cell, the terminal can actively request, and the network equipment can also be allocated.
As shown in fig. 2, the SSBs 0 to 7 scanned by the terminal UE1 and the terminal UE2 have different signal strengths, so that the UE1 selects the PRACH resource associated with the SSB with the strongest signal to access the cell of the network device, and the UE selects the PRACH resource associated with the SSB with the strongest signal to access the cell of the network device.
Because the range of the cell covered by each network device is wide, the terminal in the coverage area can scan the SSB set transmitted by the network device and select the PRACH resource associated with different SSBs to access the cell.
It should be noted that, when the terminal accesses a cell covered by the network, a request needs to be sent to the network device, where the request may include information such as time for sending the access request and frequency points for requesting access, and the network device may detect information such as time for sending the request and frequency points for the UE after receiving the request.
The cell of the network device is accessible to all terminals within the coverage area. Therefore, in the current time period, the network device may count the number of terminals accessed on the synchronization signal block in each antenna direction. Taking the target SSB in the target antenna direction as an example, the number of the accessed terminals is the first number of terminals.
S102, acquiring a terminal quantity threshold value served by the uplink resource;
for the network device, each SSB is associated with a limited uplink resource, the number of terminals that can be served is limited, and each synchronization signal block corresponds to a terminal number threshold, so that the terminal number threshold served by the uplink resource associated with the target SSB can be determined by reading the pre-stored terminal number threshold of each synchronization signal block.
The threshold of the number of terminals may be the maximum number of terminals, or the number of terminals corresponding to the signal quality being the quality threshold.
It can be understood that each SSB corresponds to a signal identifier, and the network device stores the correspondence between the signal identifier and the threshold of the number of terminals, as shown in table 1, if the target SSB is SSB1, the corresponding threshold of the number of terminals is X1.
TABLE 1
| Signal identification | Terminal number threshold |
| SSB1 | X1 |
| SSB2 | X2 |
| SSB3 | X3 |
| … | … |
S103, based on the first terminal number and the terminal number threshold, adjusting the transmitting power of the target synchronization signal block.
When the number of terminals accessed to the same SSB is large, the communication quality is affected, and even the access fails, or when the number of terminals accessed to the same SSB is small, the number of terminals accessed to the SSB is small, which results in resource waste.
Therefore, in order to ensure that the number of terminals accessing the target synchronization signal block is proper, so that the communication quality is better and resources are not wasted, if the number of the first terminals is greater than the threshold value of the number of the terminals, which indicates that the number of the terminals accessing the target synchronization signal block is greater, the transmitting power of the target synchronization signal block is reduced; or, if the ratio of the first number of terminals to the threshold of the number of terminals is greater than the first threshold, indicating that the number of terminals accessed is greater, reducing the transmitting power of the target synchronization signal block. If the difference value between the first terminal quantity and the terminal quantity threshold is greater than a fourth threshold, indicating that the number of the accessed terminals is less, increasing the transmitting power of the target synchronization signal block; or if the ratio of the first number of terminals to the threshold of the number of terminals is smaller than a fifth threshold, which indicates that the number of accessed terminals is small, increasing the transmitting power of the target synchronization signal block.
And retransmitting the synchronous signal block set according to the adjusted transmitting power, so that the signal intensity of each synchronous signal block scanned by each terminal is different, and adjusting the counted cells according to the signal intensity in the scanned synchronous signal blocks.
In the embodiment of the application, in a current time period, a network device determines the number of first terminals served by uplink resources associated with a transmitted target synchronization signal block in a certain direction and a threshold of the number of terminals served by the uplink resources, and adjusts the transmission power of the target synchronization signal block based on the number of the first terminals and the threshold of the number of the terminals, so that the signal strength scanned by the terminals scanning the target synchronization signal block is changed, a proper synchronization signal block is selected for access according to the signal strength, load balancing of the uplink resources associated with each synchronization signal block can be realized, and the access success rate is improved.
Please refer to fig. 5, which is a flowchart illustrating a power adjustment method according to an embodiment of the present disclosure. The present embodiment is exemplified by applying the power adjustment method to the base station. The power regulation method may include the steps of:
s201, in the current time period, determining the number of first terminals served by uplink resources associated with a target synchronization signal block, wherein the target synchronization signal block is any synchronization signal block in a synchronization signal block set transmitted by the network equipment;
s202, acquiring a terminal quantity threshold value served by the uplink resource;
S201-S202 can be referred to as S101-S102, and are not described herein.
S203, if the number of the first terminals is larger than the threshold value of the number of the terminals, reducing the transmitting power of the target synchronous signal block; or, if the ratio of the first number of terminals to the threshold of the number of terminals is greater than a first threshold, reducing the transmitting power of the target synchronization signal block.
Assuming that the first number of terminals is X0, the threshold of the number of terminals is X1, and the first threshold is a, when X0> X1, or X0/X1> a, it indicates that the number of terminals accessed on the target SSB is large at this time, and in order to achieve load balancing of uplink PRACH resources associated with each SSB, it is necessary to reduce the transmission power of the SSB, so that the signal strength of the SSB scanned by the terminal becomes weak, and to select another PRACH resource associated with an SSB having a better signal strength for access.
The transmitting power of the target synchronous signal block can be gradually reduced according to a first preset step length; or reducing the transmission power of the target synchronization signal block from the current transmission power to a specified transmission power, wherein the specified transmission power is smaller than a second threshold value.
It should be noted that, gradually reducing the transmission power of the target SSB may be performed after each adjustment, or may be performed after a plurality of adjustments are performed and the specified transmission power is reached.
For the determination of the specified transmission power which is adjusted for multiple times and reaches the required adjustment, a first difference value between the first terminal number and the terminal number threshold is calculated, and based on the corresponding relationship between different difference value ranges and the transmission power, a difference value range to which the first difference value belongs and a first transmission power corresponding to the difference value range are determined.
S204, transmitting the target synchronization signal block by the reduced transmitting power, and acquiring the number of second terminals served by uplink resources associated with the target synchronization signal block in the current time period;
if the transmission power is adjusted in a gradual adjusting mode, the reduced transmission power is the power adjusted according to the preset step length each time or the appointed power adjusted for multiple times according to the preset step length; and if the adjustment is directly carried out, the reduced transmitting power is the appointed transmitting power.
And sending the SSB according to the adjusted transmission power, and counting the number of second terminals of the accessed terminals again in the same time period after the terminals scan and access again.
S205, when the number of the second terminals is smaller than a third threshold value, recovering the transmitting power of the target synchronization signal block.
The third threshold may be understood as a smaller value, and if the number of the second terminals is smaller than or equal to the third threshold, it indicates that the transmission power has been adjusted to a smaller value, so that the number of the terminals accessed is smaller, and therefore, the transmission power of the target SSB may be recovered, thereby facilitating switching of terminals accessed through PRACH resources associated with other SSBs to the SSB, so as to implement load balancing of uplink PRACH resources associated with each SSB.
The transmitting power of the target synchronizing signal block can be gradually increased according to a second preset step length; or, the transmitting power of the target synchronization signal block is increased from the specified transmitting power to the current transmitting power.
For the determination of gradually increasing the transmission power of the target synchronization signal block, a second difference between the number of the second terminals and the third threshold may be calculated, based on the correspondence between different difference ranges and the transmission power, a difference range to which the second difference belongs and a second transmission power corresponding to the difference range are determined, and the transmission power of the target synchronization signal block is gradually increased to the second transmission power according to a second preset step length.
S206, if the difference value between the first terminal quantity and the terminal quantity threshold is larger than a fourth threshold, increasing the transmitting power of the target synchronous signal block; or if the ratio of the first number of terminals to the threshold of the number of terminals is smaller than a fifth threshold, increasing the transmitting power of the target synchronization signal block.
The fourth threshold may be understood as a smaller value, and if the difference between the number of the first terminals and the number of the terminals threshold is greater than the fourth threshold, it indicates that the number of the terminals accessing the cell through the PRACH resource associated with the target SSB is smaller, and in order to achieve load balancing of the uplink PRACH resource associated with each SSB on the network device, the terminals accessing the uplink PRACH resource associated with other SSBs or the terminals not accessing the cell of the network device may access the cell through the PRACH resource associated with the target SSB, the transmission power of the target SSB may be increased. And re-transmits after adjustment for terminal scanning and access.
The manner of adjusting the transmission power up is similar to the manner of adjusting the transmission power down, and is not described herein again.
S207, when the next time period is reached, executing the step of determining the number of the first terminals served by the uplink resource associated with the target synchronization signal block.
When the next time period is reached, the transmit power of each SSB is adjusted in the same manner as the previous period to optimize the communication quality.
In the embodiment of the application, in a current time period, a network device determines a first terminal quantity served by an uplink resource associated with a transmitted target synchronization signal block in a certain direction and a terminal quantity threshold served by the uplink resource, and based on the first terminal quantity and the terminal quantity threshold, when it is determined that there are more terminals accessing the target synchronization signal block, the transmission power of the target synchronization signal block is reduced to reduce the number of terminals accessing the target synchronization signal block; when the number of terminals accessing the target synchronous signal block is determined to be less, the transmitting power of the target synchronous signal block is increased so as to increase the number of terminals accessing the target synchronous signal block; therefore, the load balance of the uplink resources associated with each synchronous signal block can be realized, and the access success rate is improved. Meanwhile, the uplink resource load balance associated with each synchronous signal block can be continuously maintained through periodic detection and adjustment, and the communication quality is effectively improved.
