All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The embodiment of the application provides a power control method and device, which are used for avoiding power waste and improving power occupancy rate.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

The technical scheme provided by the embodiment of the application can be suitable for various systems, in particular to a 5G system. For example, suitable systems may be global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) universal packet Radio service (general packet Radio service, GPRS), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), long term evolution-advanced (long term evolution advanced, LTE-a), universal mobile system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX), 5G New air interface (New Radio, NR), and the like. Terminal devices and network devices are included in these various systems. Core network parts such as evolved packet system (Evloved Packet System, EPS), 5G system (5 GS) etc. may also be included in the system.

The following will be described first:

the repeater is a wireless signal relay product, and is a scheme capable of effectively supplementing coverage capability of network side equipment in network deployment.

The repeater is a wireless signal relay product and can be used as one of the necessary means for achieving the goal of 'small capacity and large coverage'. The advantage of using repeater to perform network deployment is that firstly, network coverage can be ensured without increasing the number of devices at the network side, and secondly, the cost is far lower than that of a micro-cellular system with the same effect. Repeater is a preferred solution to the extended coverage capability of a communication network. Compared with the network side equipment, the device has the advantages of simple structure, less investment, convenient installation and the like, can be widely used for blind areas and weak areas which are difficult to cover, such as various places including markets, hotels, airports, wharfs, stations, gymnasiums, entertainment halls, subways, tunnels, highways, islands and the like, improves the communication quality, and solves the problems of call drop and the like.

The novel repeater NCR is formed by adding a control plane protocol stack on the basis of the original repeater, network side equipment can control functions of the repeater by sending network control information, in a communication system, the characteristics of the network control repeater can be supported, and when the repeater serves a certain network side equipment, the network side equipment is required to be capable of configuring beam information for the repeater. The beam indication information in this patent refers to: and transmitting and receiving beam information between the repeater and the network side equipment.

Compared with the traditional repeater, the repeater is mainly characterized in that network side equipment can perform network control on the repeater serving the repeater.

Fig. 1 is a schematic diagram of a link structure of a repeater provided in the related art, as shown in fig. 1, in which a link relationship among a network side device, a repeater and a terminal is identified, wherein two links exist between the network side device and the repeater, one is a control link (C-link), and the other is a Forwarding Link (FLB). Both the C-link and the FLB have uplink and downlink, and FDM (simultaneously) or TDM modes can be adopted by the C-link and the FLB in the actual resource allocation process.

The C-link and FLB uplinks may be transmitted in a simultaneous simultaneously or TDM fashion. When the TDM mode is adopted, the C-link and the FLB are not transmitted on the same symbol, and when the Simultaneously mode is adopted, the C-link and the FLB can be transmitted on the same symbol, and the C-link and the FLB occupy different frequency domain resource positions.

Fig. 2 is a schematic structural diagram of a repeater provided in the related art, and as shown in fig. 2, the uplink C-link and FLB structures of the repeater may be two ways, one is an independent PA structure, and the other is a unified PA structure.

It should be noted that, the repeater to which the power control method of each embodiment of the present application is applied may include a repeater with the above structure, but is not limited to the repeater with the above structure; any repeater that has two different links with the network side device at the same time is suitable for each embodiment of the present application.

Fig. 3 is a schematic flow chart of a power control method according to an embodiment of the present application, as shown in fig. 3, where the method is applied to a repeater, that is, an execution body of the method may be the repeater, and the method includes the following steps:

step 300, determining a target power adjustment factor;

and step 310, controlling the power transmitted between the repeater and the network side equipment based on the target power adjustment factor.

Optionally, for the link C-link and FLB between the repeater and the network side device, the link C-link and FLB may exist at the same time, and if power control is not performed, power may be sent in an over-power manner; the C-link and FLB may not exist at the same time, and may not be able to transmit full power, resulting in power waste, and thus power control is required.

For example, when a simultaneous transmission mode (simultaneously mode) is adopted, the C-link and the FLB may be transmitted on the same symbol, where the C-link and the FLB occupy different frequency domain resource positions; if the maximum power of a single link is directly set in the related art, and power control is performed according to the simultaneous existence of the C-link and the FLB, power waste may be caused, full power transmission cannot be used, and if power control is performed according to the non-simultaneous existence of the C-link and the FLB, strong interference may be caused to occur beyond the maximum transmission power. Therefore, the target power adjustment factor can be set to indicate the dB value of the offset of the maximum power value relative to the maximum transmission power of the repeater during power adjustment, so that more proper power adjustment is realized, power waste is avoided, and the power occupancy rate is improved.

Optionally, the target power adjustment factor is used to characterize: the maximum power value of the link between the repeater and the network side device is offset dB value from the maximum transmission power of the repeater when power adjustment is performed.

For example, the target power adjustment factor may be used to characterize the dB value of the offset of the C-link maximum power value relative to the repeater maximum transmit power.

For example, the target power adjustment factor may be used to characterize the dB value of the offset of the TDM maximum power value relative to the maximum transmit power of the repeater.

Optionally, after the target power adjustment factor is determined, power control may be performed on transmissions between the repeater and the network-side device based on the target power adjustment factor. For example, for the simultaneity mode, since the C-link and the FLB do not always exist at the same time, power adjustment and control are performed based on the target power adjustment factor on the symbols that are transmitted at the same time and not transmitted at the same time, so that the situation that the C-link and the FLB do not exist at the same time and approach to or use full power transmission as much as possible can be achieved, and the transmission power does not exceed the full power when the C-link and the FLB exist at the same time.

According to the power control method, the target power adjustment factor for power control is determined, and then the power transmitted between the repeater and the network side equipment is controlled based on the target power adjustment factor, so that power waste is avoided, and the power occupancy rate is improved.
