  • Patent number: 10736106
    Abstract: A node of a wireless network transmits information to a user equipment over an aggregated carrier that includes a primary carrier having a first set of primary carrier time/frequency resources and a secondary carrier having a second set of secondary carrier time/frequency resources. Synchronization signals and/or reference symbols are transmitted to the user equipment on the secondary carrier less often than on the primary carrier. An indication of when and/or how often the synchronization signals and/or reference symbols will be transmitted to the user equipment on the secondary carrier may also be transmitted to the user equipment over the primary carrier. By transmitting synchronization signals and/or reference symbols to the user equipment on the secondary carrier less often than on the primary carrier, resources of the secondary carrier may be conserved, energy efficiency of the secondary carrier may be increased, and/or interference with other cells may be reduced or prevented.

  • Patent number: 10735165
    Abstract: Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-overlapping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particular region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

  • Publication number: 20200233334
    Abstract: Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe. When the user equipment detects that the DCI message indicates that a CSI-RS transmission from the LA SCell is present in the subframe, it processes a CSI-RS measurement. When the user equipment detects that the DCI message does not indicate that a CSI-RS transmission from the LA SCell is present in the subframe, it refrains from processing the CSI-RS measurement.

  • Patent number: 10674531
    Abstract: Systems and methods for collision handling between transmissions using a first Transmission Time Interval (TTI) and transmissions using a second TTI, such as a legacy TTI and a short TTI (sTTI), are provided. In some embodiments, the proposed solution helps the UE handle collisions between transmissions using legacy TTI in UL and overlapping transmissions using short TTI in UL. In some embodiments, this is accomplished by a wireless device adapted for uplink transmissions using a first TTI or a second TTI where the second TTI is shorter than the first TTI. The method includes altering at least one transmission of a first transmission using the first TTI and a second transmission using the second TTI based on a determination that a collision is to occur between the first transmission and the second transmission.
