Resource allocation method based on one-to-many matching in heterogeneous network
A resource allocation, multi-matching technology, applied in location-based services, machine-to-machine/machine-type communication services, advanced technologies, etc., can solve problems such as less consideration of macro-cell user spectrum resource interference management issues, and achieve improved Spectral efficiency and system throughput, reducing computational complexity, and reducing the effect of same-layer interference

[0065] S411. Judging the current matching status of sub-channel n and multiplexing user k, if sub-channel n and multiplexing user k are currently in an unmatched state, and the first preference list of multiplexing user k in the t-th round of matching If not empty, execute step S421;
[0066] S421. If the multiplexing user k causes interference to the macro cell user on the sub-channel n greater than interference margin Then execute step S431, if Then execute step S441;
[0067] S431. For the multiplexing users whose sub-channel n has been matched at present, find the multiplexing users whose priority is lower than the multiplexing user k in the second preference list from the sub-channel n, and add these multiplexing users to the set sequentially from Delete the multiplexing user with the lowest priority, and update the interference margin of the current subchannel n until Execute step S441; if All reused users of are deleted, and Then subchannel n rejects t...
