  • Patent number: 10348328
    Abstract: Programming of frozen bits of first stage control channel information block enables scheduling information to be included for the second stage of the control channel information. By including some of the scheduling information for the second stage in the first stage frozen bits, the size of the first stage information blocks can be reduced, reducing the overhead required to transmit control information for the traffic channel. In an embodiment, the frozen bits can convey scheduling information that is lower priority than the scheduling information conveyed in the non-frozen bits of the first stage control channel information block. In another embodiment, the frozen bits can include parity bits, or cyclic redundancy check bits that are masked with the scheduling information.

    Abstract: Antenna selection and reassignment in multiple radio access technology (RAT) communication systems with unlicensed spectrum is disclosed. Aspects include a user equipment (UE) monitoring for a channel reserving signal in each frame from multiple transmission sources. If no channel reserving signal is detected, then the UE reassigns one or more of the antennas previously assigned to the transmission sources with no activity detected. Additional aspects include base stations that determine a clear channel assessment (CCA) status for each of unlicensed carrier designated for transmission to a UE. The base station will transmit a receive antenna usage adjustment signal to the UE based on the determined CCA status.

  • Patent number: 10264550
    Abstract: Systems and methodologies are described that facilitate employing a paging indicator channel in connection with high speed channels in a wireless communications network. A paging indicator transmission can be sent on the paging channel to one or more mobile devices. The paging indicator indicates that additional information such as a full paging messages, other control plane data or other user plane data is expected to be transmitted at a specific time instant (e.g., subframe) on the associated high speed channel. A set of parameters can be transmitted on common channels that specify a set of associated subframes in a high speed channel. Mobile devices can analyze the set of parameters to determine the associated subframes and receive the subframes in accordance with a schedule.

    Abstract: Methods, apparatus, and systems for implementing hierarchical and lossless packet preemption and interleaving to reduce latency jitter in flow-controller packet-based networks. Fabric packets are divided into a plurality of data units, with data units for different fabric packets buffered in separate buffers. Data units are pulled from the buffers and added to a transmit stream in which groups of data units are interleaved. Upon receipt by a receiver, the groups of data units are separated out and buffered in separate buffers under which data units for the same fabric packets are grouped together. In one aspect, each buffer is associated with a respective virtual lane (VL), and the fabric packets are effectively transferred over fabric links using virtual lanes. VLs may have different levels of priority under which data units for fabric packets in higher-priority VLs may preempt fabric packets in lower-priority VLs.
