  • Patent number: 11228972
    Abstract: Baseband circuitry receives and processes measurement reports from multiple User Equipment (UEs) at multiple locations and responsively determines radio metric variances at the multiple locations. The baseband circuitry receives attachment signaling from a new UE, determines the location for the new UE, and determines a measurement time period for the new UE based on the radio metric variance at the location of the new UE. The baseband circuitry transfers the measurement time period to the new UE. The baseband circuitry receives and processes a measurement report from the new UE and determines to add a secondary access node based on a radio metric for the secondary access node in the new measurement report. The baseband circuitry transfers network signaling to the secondary access node to serve the new UE and transfers additional user signaling to new UE to attach to the secondary access node.

  • Patent number: 11224036
    Abstract: The method for transmitting control information in a mobile communication system includes: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. A capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.

  • Patent number: 11224010
    Abstract: Methods and apparatuses exemplified in this disclosure provide mechanisms for a wireless communication device to indicate its Radio Access Technology (RAT) preferences to a wireless communication network, and for a wireless communication network to consider the RAT preferences of a given device when deciding which RAT the device will use. As a non-limiting example of the advantages flowing from these mechanisms, devices operating within a network that includes or is associated with multiple RATs can indicate their preferences for which RAT they use, while still allowing the network to retain control of the RAT selection decisions. Such flexibility offers significant advantages in 5G networks that provide tight integration between multiple RATS—e.g., between LTE and NR air interfaces. However, the methods and apparatuses disclosed herein are not limited to 5G networks.

  • Patent number: 11219052
    Abstract: According to the present disclosure, behaviors of User Equipment (UE) and base station (BS) pertinent to Scheduling Request (SR) and/or Buffer Status Report (BSR) as well as resource management in short Transmission Time Interval (sTTI) relevant scenarios are discussed. UE may firstly determine if the SR is triggered by a buffer status change of a delay-critical data which needs a sTTI. If so, UE will send the SR to BS on a first type of uplink control channel designed for sTTI. Otherwise, UE will send the SR to the base station on a second type of uplink control channel designed for legacy TTI.

  • Patent number: 11166243
    Abstract: A method for apportioning uplink transmission power in a mobile communication device is disclosed including determining a maximum power limit for the mobile communication device, identifying a first wireless transmission scheduled to transmit at a first power and a first time according to a first radio access technology (RATI); identifying a second wireless transmission scheduled to transmit at a second power and a second time according to a second radio access technology (RAT2). An aggregate transmission power required for transmission is calculated and transmission is apportioned asymmetrically as to at least one of power and/or time between the first wireless transmission and the second wireless transmission where the required aggregate transmission power exceeds said maximum power limit. Transmitting at least one of said first and/or second wireless transmission according to said asymmetrical apportionment results in transmission within specified power limits.

    Abstract: Systems and methods are described for radio frequency (RF) calibration in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”) exploiting uplink/downlink channel reciprocity. The RF calibration is used to compute open-loop downlink precoder based on uplink channel estimates, thereby avoiding feedback overhead for channel state information as in closed-loop schemes. For example, a MU-MAS of one embodiment comprises a wireless cellular network with one or multiple beacon stations, multiple client devices and multiple distributed antennas operating cooperatively via precoding methods to eliminate inter-client interference and increase network capacity.
