Abstract
The present disclosure relates generally to systems and methods for a fractional loading scheme for broadcast/multicast traffic. In one example, the method includes determining a fractional loading factor for a portion of a wireless network and selecting wireless network resources from a resource pool allocated to single-cell broadcast traffic based on the fractional loading factor. Single-cell broadcast traffic is then transmitted using the wireless network resources.
Claims24
A method comprising:
- determining, by a base station, a fractional loading factor using a duty cycle of a base station, wherein the fractional loading factor is used for transmitting single-cell broadcast traffic in a wireless network, and wherein the fractional loading factor is based upon a percentage of resources from a resource pool allocated to single-cell broadcast traffic;
- transmitting single-cell broadcast traffic using the fractional loading factor resources, wherein the fractional loading factor enables the base station to identify resources used for the single-cell broadcast based upon a cell-ID of the broadcast traffic, wherein the fractional loading factor uses an average capacity value obtained as a function of a wireless capacity in a time-frequency resource using a number of transmissions among neighboring cells;
- and
- transmitting unicast traffic using non-selected resources from the resource pool, wherein transmitting further comprises transmitting at least a portion of the unicast traffic at a reduced transmit power.

A method comprising:
- determining, by a base station, a fractional loading factor for a portion of a wireless network, wherein the fractional loading factor is based upon a capacity in a time-frequency resource;
- randomly selecting, by the base station, wireless network resources from a resource pool allocated to single-cell broadcast traffic based on the fractional loading factor;
- informing, by the base station, at least one mobile terminal of the wireless network resources selected for use for single-cell broadcast;
- and
- transmitting, by a base station, single-cell broadcast traffic using the wireless network resources;
- and
- transmitting unicast traffic using non-selected resources from the resource pool, wherein transmitting further comprises transmitting at least a portion of the unicast traffic at a reduced transmit power.

A method comprising:
- receiving, by a wireless receiver, information about single-cell broadcast resources used for fractional loading transmissions in a cell of a wireless network by a base station, the single-cell broadcast resources comprising a percentage of resources from a resource pool allocated to single-cell broadcast traffic;
- decoding the received single-cell broadcast resource information;
- receiving, by the wireless receiver, broadcast information transmitted by the base station using the single-cell broadcast resources;
- decoding the received broadcast information, wherein the decoding uses either a sub-frame identification of the broadcast resource or a cell-ID of the base station from the received single-cell broadcast resource information;
- and
- receiving, by the wireless receiver, unicast traffic using non-selected resources from the resource pool, wherein at least a portion of the unicast traffic is received at a reduced transmit power.

A method comprising:
- identifying, by a wireless receiver, information about single-cell broadcast resources used for fractional loading transmissions in a cell of a wireless network based on at least one of a cell identifier and a subframe identifier, the single-cell broadcast resources comprising a percentage of resources from a resource pool allocated to single-cell broadcast traffic;
- receiving, by the wireless receiver, broadcast information transmitted by a base station using the single-cell broadcast resources;
- decoding the received broadcast information, wherein the decoding uses either the sub-frame identifier of the broadcast resource or a cell-ID of the base station;
- and
- receiving, by the wireless receiver, unicast traffic using non-selected resources from the resource pool, wherein at least a portion of the unicast traffic is received at a reduced transmit power.
2 more elements

- transmitting single-cell broadcast traffic using the wireless network resources;
- and
- transmitting unicast traffic using non-selected resources from the resource pool, wherein at least a portion of the unicast traffic is received at a reduced transmit power.
