Abstract
Methods and systems for providing data are disclosed. An optimal set of subcarriers can be determined for a data transmission when a plurality of devices have requested the data transmission. The optimal set of subcarriers can be determined based on similarities or differences between parameters assigned to subcarriers in capability profiles. Capacity loss and other information can be determined based on the similarities or the differences among corresponding parameters of the capability profiles. The data transmission can be transmitted to the plurality of devices via the optimal set of subcarriers.
Claims20
A method, comprising:
- accessing, in response to a request for a data transmission, capability information for a plurality of devices that requested the data transmission, wherein the capability information indicates capabilities associated with each of the plurality of devices for a plurality of subcarriers;
- determining, based on the capability information, a maximum capability and a minimum capability for each subcarrier of the plurality of subcarriers;
- determining, based on a difference between the maximum capability and the minimum capability for each subcarrier of the plurality of subcarriers, a plurality of capacity losses for the plurality of subcarriers;
- determining, based on the plurality of capacity losses and the data transmission, an optimal set of subcarriers for the data transmission;
- and
- performing the data transmission to the plurality of devices via the optimal set of subcarriers.
A method, comprising:
- accessing, in response to a request for a data transmission, capability profiles for a plurality of devices that requested the data transmission, wherein the capability profiles associate a plurality of available subcarriers with corresponding parameter values;
- comparing, for one or more subcarriers of the plurality of subcarriers, the corresponding parameter values;
- determining an optimal set of subcarriers for the data transmission based on the comparison of the parameter values;
- and
- performing the data transmission to the plurality of devices via the optimal set of subcarriers.
A method, comprising:
- accessing, in response to a request for a data transmission from a plurality of devices requesting the data transmission, a plurality of capability profiles that associate a plurality of available subcarriers with corresponding parameters values;
- determining at least one group of optimal subcarriers from among the plurality of available subcarriers based on a comparison, for one or more of the available subcarriers, of the parameters values of the plurality of capability profiles;
- determining a first multicast transmission group that comprises the at least one group of optimal subcarriers;
- and
- performing a multicast data transmission via the first multicast transmission group.
