  • Patent number: 11901983
    Abstract: Selectively assigning uplink transmission layers for uplink transmissions from wireless devices to access nodes based on any combination of uplink usage characteristics and signal conditions. Wireless devices configured to transmit uplink data on one or more orthogonal transmission layers from each antenna. Instructing wireless devices to add transmission layers is based on an uplink usage and other characteristics such as type of transmission, time of day, distance from serving access node, etc.

  • Patent number: 9363748
    Abstract: Wireless device information comprising a power level of a successful access probe sent by wireless devices to an access node and a location of each of the wireless devices relative to the access node is acquired. Based on the wireless device information, a first access probe power level is determined. The determined first access probe power level is provided to a new wireless device and an access probe is received from the new wireless device using the first access probe power level.

  • Patent number: 9049582
    Abstract: A method and apparatus to manage a communication device are disclosed. The method includes receiving a first message comprising a first battery charge level of the communication device and a first time associated with the first battery charge level, storing a first database entry comprising information comprised in the first message, in a battery charge database, determining based on data from the battery charge database, or retrieving from a power management database, a power management efficiency factor of the communication device, determining an expected operational time of the communication device based on the first message and the power management efficiency factor, and transmitting an indication that the battery charge level is low when the determined operational time remaining meets an expected operational time criteria, to the communication device.

  • Patent number: 8964614
    Abstract: A method and system to manage idle mode operation of a communication device are disclosed. The method includes receiving from the communication device a request to enter idle mode comprising a request to enable automatic renewal of an internet protocol (IP) address currently assigned to the communication device, transmitting, to an IP address allocation unit which allocated the IP address to the communication device, the idle mode request, receiving, from the IP address allocation unit, an idle mode response comprising an IP lease update acknowledgement associated with the idle mode request, transmitting, to the communication device, the idle mode response, enabling automatic renewal of the IP address, configuring an idle mode timer, and transmitting to the IP address allocation unit, an IP lease update request corresponding to the IP address, when the idle mode timer expires and the communication device is in idle mode.

  • Patent number: 8880007
    Abstract: In systems and methods of reducing latency in a wireless communication system, a first signal of a first radio access technology and a second signal of a second radio access technology are received at a first antenna and a second antenna of a wireless device. From a first circulator the first signal received at the first antenna and the second antenna are received and combined to generate a combined first signal. In addition, from a second circulator the second signal received at the first antenna and the second antenna are received and combined to generate a combined second signal. While receiving the first signal of the first radio access technology, a call request is received over the second signal of the second radio access technology.

  • Patent number: 8660507
    Abstract: A signal is received at a plurality of antennas of a wireless device, and a signal strength indicator is calculated for the signal received at each of the plurality of antennas. From the plurality of antennas, a subset of antennas associated with the highest signal strength indicators are selected, and maximum ratio combining is performed on the signals received by the selected subset of antennas.

  • Patent number: 8588728
    Abstract: A method and apparatus to manage the paging cycle of a communication device are disclosed. The method includes receiving, by an element of a communication system, at least one message comprising an idle mode request, a battery charge level of a battery of the communication device, and a desired paging information from the communication device, from the communication device, determining a paging information for the communication device based on the battery charge level by selecting a first paging cycle when the battery charge level meets a charge level criteria and selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, the second paging cycle being longer than the first paging cycle, and transmitting a response message comprising the determined paging information to the communication device.
