an obtaining module configured to obtain a quality condition of two or more of the multiple paths; and
an adjusting module configured to adjust, using a hardware processor, the transmission of the data frames in the data queue across the multiple paths based on the quality condition obtained for each of the multiple paths, wherein the adjusting module further comprises:
a balancing module configured to, in response to the quality condition of at least one of the multiple paths satisfying a second threshold range, balance the transmission traffic in each of the multiple paths, wherein the second threshold range is a range of values associated with the quality condition, wherein the balancing module further comprises:
a second predicting module configured to predict power consumption for transmitting one data frame in each of the multiple paths; and
a second transmitting module configured to transmit the data frames in a path corresponding to a minimum power consumption.

2. The apparatus according to claim 1 , wherein the apparatus is implemented on a Medium Access Control (MAC) layer.

3. The apparatus according to claim 1 , wherein the adjusting module comprises:
a data transmitting module configured to, in response to the quality condition of each of the multiple paths satisfying a first threshold range, transmit same data frames in the data queue in each of the multiple paths;
wherein the first threshold range is a range of values associated with the quality condition.

4. The apparatus according to claim 1 , wherein the balancing module comprises:
a first predicting module configured to predict a predicted completion time that is spent in transmitting one data frame in each of the multiple paths; and
a first transmitting module configured to transmit the data frames in a path corresponding to a shortest predicted completion time.

5. The apparatus according to claim 1 , wherein the quality condition is any one or combination of: Block Error Rate, Quality of Service Indicator and Channel Quality Indicator.

6. The apparatus according to claim 1 , wherein the first device and the second device are a base station and an access device, respectively.

7. An apparatus for receiving data based on multipath, comprising:
an establishing module configured to establish Worldwide Interoperability for Microwave Access (WiMAX) connection-based multiple paths between a first device and a second device;
a receiving module configured to receive a plurality of data frames from a data queue across two or more of the multiple paths; and
a processing module configured to process, using a hardware processor, the received plurality of data frames based on a quality condition obtained for each of the multiple paths, wherein transmission of the received plurality of data frames in a data queue is adjusted across the multiple paths for receiving balanced transmission traffic based on the quality condition, the transmission traffic being balanced by:
predicting power consumption for transmitting one data frame in each of the multiple paths; and
transmitting the data frame in a path corresponding to a minimum power consumption.
