摘要： One or more devices determine uplink signal strength for a machine-to-machine (M2M) device using a wireless access network. The one or more devices identify a default uplink transmission mode that requires the M2M device to employ transmission time interval (TTI) bundling, when the uplink signal strength is below a particular threshold, and identify a default uplink transmission mode that requires the M2M device to not employ TTI bundling, when the uplink signal strength is not below the particular threshold. The one or more devices store, in a memory, the default transmission mode for the M2M device. The one or more devices retrieve, from the memory and during a wake-up time window associated with the M2M device, the default transmission mode for the M2M device and construct, for the M2M device, an uplink scheduling grant based on the stored default transmission mode.

摘要： A system may include a plurality of wireless devices, each wireless device including a time source and configured to selectively communicate with at least one other of the plurality of wireless devices by way of a packet-based time precision protocol. The plurality of wireless devices may include a first wireless device and a second wireless device, the first wireless device being configured to determine whether the first wireless device and the second wireless device are in selective communication over a single-hop wireless link; determine a one-way delay over the single-hop wireless link by way of at least one packed-based time precision protocol message; and calculate a distance measurement between the first wireless device and the second wireless device based at least in part on the one-way delay.

摘要： A device receives, from mobile devices, scheduling requests for voice packets, and assigns grants to the scheduling requests. The device further determines whether there is network congestion in a network associated with the device. The device also selects a grant, from the grants, when there is network congestion, and drops a voice packets associated with the selected grant. The device assigns physical resource blocks (PRBs) to one or more of the grants that are associated with one or more of the voice packets that are not dropped.

摘要： A machine-type communications (MTC) device may attempt a network attach operation corresponding to a wireless network, and receive quality of service information, from the wireless network, in response to the network attach operation failing. The MTC device may determine a back-off time based on the quality of service information received from the wireless network. The back-off time may include a duration of time before re-attempting the network attach operation. The MTC device may re-attempt the network attach operation in response to detecting an expiration of the back-off time.

摘要： Systems and methods for scheduling wireless communications of a base station with multiple user mobile stations involve grouping the user mobile stations in clusters based on a predetermined criterion, such as a Quality of Service (QOS) profile of a user mobile station. Each cluster is assigned with a cluster weight factor that defines a priority level of the cluster. For each user mobile station in each cluster, a priority index may be determined based on the cluster weight factor of a respective cluster, and throughput and fairness factors respectively selected to maximize throughput and provide fairness to user mobile stations. The user mobile stations may be served in an order based on their priority indexes.
