  • Patent number: 11368890
    Abstract: Predicting small cell capacity and coverage to facilitate offloading of macrocell capacity is presented herein. A system selects a group of candidate locations for placement of respective small cells to facilitate offloading, via the respective small cells, of traffic from respective macrocells corresponding to the candidate locations—the respective small cells including first transmission powers that are less than second transmission powers of the respective macrocells. Further, for each candidate location of the group of candidate locations, the system determines an estimated amount of traffic capacity of a small cell of the respective small cells that has been presumed to have been placed at the candidate location, and determines estimated signal strengths of respective signals that have been predicted to have been received from the small cell at respective portions of a grid of a defined signal coverage area corresponding to the candidate location.

  • Patent number: 11350313
    Abstract: A method and system for controlling uplink communication from a user equipment device (UE) that has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes comparing a level of antenna pattern efficiency associated with the first air-interface connection with a level of antenna pattern efficiency associated with the second air-interface connection and, based at least on the comparing, configuring an uplink split ratio defining a distribution of uplink user-plane data flow of the UE between at least the first air-interface connection and the second air-interface connection. In an example implementation, this could involve configuring one of the air-interface connections as a primary uplink path to which the UE restricts its uplink communication unless and until a trigger occurs for transitioning the UE to operate in an split-uplink mode.

  • Patent number: 11343745
    Abstract: User equipment receives first connection priority information. In accordance with the first connection priority information, the mobile communication device establishes a first wireless communication link between the user equipment and a first wireless network to communicate first communications. A controller/management resource provides notification of second connection priority information to be used instead of the first connection priority information. In response to detecting a trigger event in which the user equipment is operated to communicate second communications, the user equipment uses the second connection priority information as a replacement to the first connection priority information to establish a second wireless communication link connecting the user equipment to the second network instead of the first network.

  • Patent number: 11304212
    Abstract: Methods for scheduling data packets based on a target transmission time may include receiving, from an application layer at a first time, a data packet and an associated latency requirement. The first layer may determine based, at least in part, on the associated latency requirement, a target transmission time. The target transmission time may be a sum of a queuing delay, an expected transmit completion time, and the first time. The data packet may be queued (or scheduled for transmission) based, at least in part, on the target transmission time and an access category assigned to the data packet. The data packet may be transmitted (or scheduled for transmission) from the queue according to the target transmission time. The expected transmit completion time may be a sum of an average contention time for the access category assigned to the data packet and estimated airtime.

  • Patent number: 11265256
    Abstract: The described technology is generally directed towards selecting, by user equipment, a selected maximum transmission unit (MTU) packet size for wireless data transfer based on radio signal conditions. In one aspect, reference signal received power (RSRP) and reference signal received quality (RSRQ) are used to select the MTU packet size, e.g., by using RSRP and RSRQ as indices to a lookup table of predetermined MTU packet sizes, such as previously determined by field testing. In general, smaller MTU packet sizes are used with poorer quality radio signal conditions. The selected MTU packet size may be increased or decreased based on actual performance data and/or based on changed radio signal conditions, such as for a subsequent data transfer session. The user equipment may comprise a Cat-M device that transfers data related to Machine-Type Communications (MTC)/Machine to Machine (M2M) communications.
