  • Patent number: 11224013
    Abstract: In multicarrier networks mobile devices can be distributed amongst carriers based on different criteria. However, prioritization may cause certain devices to end up on a carrier that is not optimal for the network. When there is a deployment of different types of cells (e.g., macro cells, small cells, etc.), the cells can use the same frequency. Consequently, a priority value contained within a system information broadcast message can override the mobile default cell transition procedures and thus select a neighboring cell based on additional criteria. Thus, small cells can be deployed to offload traffic from macro cells in spite of the small cells and macro cells operating in the same frequency band.

Thereafter, the wireless communication device can send TDD uplink data to the network via the first TDD communication link, and receive TDD downlink data from the network via the second TDD communication link, such that a portion of the TDD uplink data is sent to the network at the same time a portion of the TDD downlink data is received from the network. In this manner, the transmissions of TDD uplink data and the TDD downlink data can occur simultaneously, via multiple communication links. Further, the TDD downlink data can be received in multiple, coordinated data transmissions using Long Term Evolution (LTE) multiple-input and multiple-output (MIMO) antenna diversity.

  • Patent number: 10873445
    Abstract: Systems, apparatuses, and methods for implementing a deskewing method for a physical layer interface on a multi-chip module are disclosed. A circuit connected to a plurality of communication lanes trains each lane to synchronize a local clock of the lane with a corresponding global clock at a beginning of a timing window. Next, the circuit symbol rotates each lane by a single step responsive to determining that all of the plurality of lanes have an incorrect symbol alignment. Responsive to determining that some but not all of the plurality of lanes have a correct symbol alignment, the circuit symbol rotates lanes which have an incorrect symbol alignment by a single step. When the end of the timing window has been reached, the circuit symbol rotates lanes which have a correct symbol alignment and adjusts a phase of a corresponding global clock to compensate for missed symbol rotations.
