INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A wireless device is configured to receive scheduling information at a predetermined time interval from a wireless node. The scheduling information includes a plurality of reception definitions. Each reception definition indicates a reception start time, a reception duration, and assigned frequency information. Each reception definition is derived from a wireless device identification associated with the reception definition. The wireless device is configured to receive data associated with at least one of the reception definitions. ## Claims ### Claim 1 A wireless device comprising: a transceiver; and a processor operatively coupled to the transceiver, wherein: the transceiver and the processor are configured to receive scheduling information at predetermined time intervals from a wireless node of a plurality of wireless nodes in a wireless network, the scheduling information including a plurality of reception definitions, wherein the scheduling information is received periodically and the wireless device sleeps between each receipt of the periodically received scheduling information, wherein the plurality of reception definitions have differing numbers of fields including at least one error correction field, wherein each reception definition of the plurality of reception definitions includes an indication of a reception start time, an indication of a reception duration, and an indication of assigned frequencies, and wherein each reception definition is derived from a wireless device identification associated with that reception definition; and the transceiver and the processor are further configured to, in response information in the fields of one of the reception definitions, and in response to using the at least one error correction field, receive and process data at the indicated reception start time for the indicated reception duration and at the assigned frequencies from the wireless node. ### Claim 2 (depends on 1) The wireless device of claim 1, wherein the received and processed data was received using frequency hopping. ### Claim 3 (depends on 1) The wireless device of claim 1, wherein the processor and the transceiver are further configured to receive transmission scheduling information from the wireless node for the wireless device to transmit to another wireless device. ### Claim 4 (depends on 3) The wireless device of claim 3, wherein the processor and the transceiver are further configured to transmit to the another wireless device based on the received transmission scheduling information. ### Claim 5 (depends on 3) The wireless device of claim 3, wherein the transmission to the other wireless device includes sensor data. ### Claim 6 (depends on 1) The wireless device of claim 1, wherein the scheduling information includes transmission scheduling data in addition to the plurality of reception definitions. ### Claim 7 (depends on 1) The wireless device of claim 1, wherein the indication of assigned frequencies includes an indication of a carrier frequency. ### Claim 8 (depends on 1) The wireless device of claim 1, wherein each reception definition includes an error correction field. ### Claim 9 A method comprising: receiving, by a wireless device, scheduling information at predetermined time intervals from a wireless node of a plurality of wireless nodes in a wireless network, the scheduling information including a plurality of reception definitions, wherein the scheduling information is received periodically and the wireless device sleeps between each receipt of the periodically received scheduling information, wherein the plurality of reception definitions have differing numbers of fields including at least one error correction field, wherein each reception definition of the plurality of reception definitions includes an indication of a reception start time, an indication of a reception duration, and an indication of assigned frequencies, and wherein each reception definition is derived from a wireless device identification associated with that reception definition; and in response to information in the fields of one of the reception definitions, and in response to using the at least one error correction field, receiving and processing, by the wireless device, data at the indicated reception start time for the indicated reception duration and at the assigned frequencies from the wireless node. ### Claim 10 (depends on 9) The method of claim 9, wherein the received and processed data was received using frequency hopping. ### Claim 11 (depends on 9) The method of claim 9, further comprising receiving, by the wireless device, transmission scheduling information from the wireless node for the wireless device to transmit to another wireless device. ### Claim 12 (depends on 11) The method of claim 11, further comprising transmitting, by the wireless device, to the another wireless device based on the received transmission scheduling information. ### Claim 13 (depends on 11) The method of claim 11, wherein the transmission to the other wireless device includes sensor data. ### Claim 14 (depends on 9) The method of claim 9, wherein the scheduling information includes transmission scheduling data in addition to the plurality of reception definitions. ### Claim 15 (depends on 9) The method of claim 9, wherein the indication of assigned frequencies includes an indication of a carrier frequency. ### Claim 16 (depends on 9) The method of claim 9, wherein each reception definition includes an error correction field.
