Abstract
Cooperative resource allocation method and apparatus for downlink simultaneous wireless information and power transfer are proposed. A cooperative resource allocation method for downlink simultaneous wireless information and power transfer network, which is implemented through a central processor, according to one example of embodiments, may be configured to include allocating subcarrier for wireless information transfer and power transfer; and allocating power for wireless information transfer with the allocated subcarrier and divided transfer power.
Claims16
A cooperative resource allocation method for downlink simultaneous wireless information and power transfer network, which is implemented through a central processor, comprising:
- allocating subcarrier for wireless information transfer and power transfer;
- and
- allocating power for wireless information transfer with the allocated subcarrier and divided transfer power, wherein the allocating subcarrier is configured to set candidates of subcarrier by using weighting factor, and select subcarrier having a minimum channel gain between ID receivers in the HAP among the subcarrier candidates.
A cooperative resource allocation apparatus for downlink simultaneous wireless information and power transfer network, comprising:
- a subcarrier allocating unit for allocating subcarrier for wireless information transfer and power transfer;
- and
- a power allocating unit for allocating power for wireless information transfer with the allocated subcarrier and divided transfer power, wherein the subcarrier allocating unit is configured to set candidates of subcarrier by using weighting factor, and select subcarrier having a minimum channel gain between ID receivers in the HAP among the subcarrier candidates.
