    Abstract: Techniques for sharing resources between a radio access technology (RAT) modem (e.g., an LTE modem) and a processor-based radio (e.g., a software-defined radio) are described. In an example, operation of the RAT modem establishes an extended discontinuous reception mode (eDRX) cycle with a cellular system. The RAT modem sends eDRX scheduling information, that is based at least in part on the eDRX cycle, to the processor-based radio. Operation of the processor-based radio identifies paging opportunities (POs) of the eDRX cycle, based at least in part on the eDRX scheduling information. Operation of the processor-based radio manages usage of shared resources (e.g., transmit and receive amplifiers, digital signal processing elements, memory devices, elements of physical layer(s), and/or antenna(s), etc.). The managing may be based at least in part on the identified POs. The managing avoids conflicts between the RAT modem and the processor-based radio over the shared resources.

    Abstract: Disclosed are techniques to minimize the electricity consumption of battery powered devices during network discovery and other phases of network operation. Example techniques include efficiently listening for other mains powered and battery powered devices within communication range of the battery powered device by, for example, shortening its listening window depending on how close the time reference maintained by the battery powered device is estimated to be to the time reference used by the other mains powered and battery powered devices within communication range. Other techniques include slowing the rate of listening by the battery powered device when the battery powered device is unlikely to be able to receive discovery messages or is already connected to the network. Other techniques include using knowledge of the network to listen for discovery messages on a channel or channels on which other devices are likely to be transmitting.

    Abstract: Techniques for allocating event offsets within a period of transmission are described. A mains-powered device (MPD) may act as a “parent” to one or more battery-powered devices (BPDs). The MPD may assign “event offsets” to each BPD. The event offset is a time by which the BPD's timeslot is “offset” from the start of a periodic cycle of transmissions by the MPD. Thus, each event offset indicates a time that the BPD must be “awake,” i.e., operating its radio receiver and/or performing other functionality. A BPD may spend a substantial fraction of its time in a “sleep” mode, wherein less power is used and fewer functions are performed than during a period of that BPD's event offset. Another BPD may have a different event offset. Communications by the MPD with each child BPD may be substantially uniformly distributed over the period. To increase efficiency, groups of BPDs may receive multicasts.

    Abstract: Techniques for acknowledging communications from multiple devices are described herein. For example, a device may broadcast a group acknowledgement message indicating that communications from multiple devices have been received by the device. Each acknowledgement in the group acknowledgement message may include a device identifier for a device that sent a communication (e.g., a Medium Access Control (MAC) address of the device, a hash of the MAC address of the device, etc.) and a communication identifier for the communication (e.g., a sequence number of the communication, a Cyclic Redundancy Check (CRC) code for the communication, etc.).
