However, the non-cooperative game model is difficult to guarantee a win-win situation. It can only guarantee the income of the primary user, but cannot guarantee the income of the secondary user.
At the same time, the general auction method converges slowly, and it is difficult to guarantee real-time requirements

Embodiment Construction
[0036] refer to figure 2 , the detailed implementation of the method for spectrum leasing to achieve a win-win situation in the layered cellular network of the present invention is as follows, which includes the following steps:
[0037] S1, the primary and secondary service providers perform information initialization and interaction. The primary service provider initializes the transmit power p 0 and spectrum pricing c, and broadcast the initialization message;
[0038] S2 The secondary service provider initializes the transmission power and access factor θ, adjusts the spectrum lease amount in real time according to the information broadcast by the main service provider, and reports the lease information to the main service provider.
[0039] where the initial transmit power of the fth sub-service provider is p f ; Access factor 0≤θ≤1 is used to reflect the access mode of the secondary service provider: if θ=0, the secondary service provider is in closed access mode, th...

The invention provides a spectrum leasing method in a hierarchical cellular network. The method comprises the following steps: (S1) a main service provider initializes transmitting power and spectrum pricing and broadcasts initialization information,(S2)a secondary service provider initializes transmitting power and an access factor, adjusts lease spectrum amount in real time according to the broadcast information of the main service provider and reports the lease spectrum amount and access factor information to the main service provider, (S3) the main service provider adjusts the spectrum pricing and transmitting power in real time according to the report information of the secondary service provider and broadcasting spectrum pricing information, (S4) the secondary service provider adjusts the lease spectrum amount in real time according to the received report information and reports the lease spectrum amount to the main service provider, (S5) the steps of S3 and S4 are repeatedly executed until the main service provider and the secondary service provider reach a consistent spectrum leasing agreement, and (S6) the main service provider carries out power adjustment and carries out interference compensation on the secondary service provider.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a spectrum sharing technology in a layered cellular network, in particular to a spectrum rental method for realizing win-win between layers in a layered cellular network. It can be used in various hierarchical cellular network scenarios. Background technique [0002] In recent years, mobile communication networks have an increasing demand for high-speed data services, and spatially multiplexed hierarchical cellular networks have become a research hotspot. In a hierarchical cellular network, the Secondary Service Provider (SSP) overlaps with the Primary Service Provider (Primary Service Provider), which can provide wireless coverage with lower power, thereby increasing the capacity of the system. At present, the main sub-service providers under study include femtocell, which is used for coverage within the home; picocells (Pico), which are deployed for hotspots; and relays, ...
