Uplink requests for bandwidth and/or other types of communication resources are provided. In some embodiments, a communication device can access a mapping between quality of service (QoS) metrics and communication resources. The communication device can determine a value of the QoS (e.g., a guaranteed rate, a defined traffic priority, an amount of buffered data, etc.) and can determine a communication resource element using at least the mapping and the value of the QoS metric. The communication device also can configure an uplink request for communication resources based at least on the communication resource element. In addition, the communication device can send the uplink request.
