  • Patent number: 10645709
    Abstract: A packet data transmission system comprises primary stations (PS) having signal transmitting and receiving means and antennas (PA1 to PA4) for propagating downlink signals and receiving uplink signals and a plurality of secondary stations (SS) able to roam within the coverage areas of the primary stations. Each secondary station (SS1) has signal transmitting and receiving means, a predetermined number of antennas (SA1 to SA4), and means for monitoring its radio environment. Information about the radio environment is relayed as an uplink signal to the respective primary station which modifies its mode of transmission of packet data signals. The secondary station in response to the modified mode of transmission of the downlink signals adapts its receiver resources to process the packet data signals and effect cancellation of any interference.

  • Patent number: 10624080
    Abstract: The set of resource aggregation levels available for forming an enhanced control channel message may vary from one subframe to another, based on the level of puncturing in the transmitted subframes. An example method begins with determining members of a set of aggregation levels usable to aggregate the non-overlapping subsets of resource elements for transmitting downlink control information. This determining is based on a puncturing level to be used for the transmission of the downlink control information. Downlink control information for the given subframe is mapped to one or more non-overlapping subsets of resource elements in the at least one block of time-frequency resources, according to an aggregation level selected from the determined set, and then transmitted, in the one or more non-overlapping subsets. This method may be repeated for each of several subframes, where the puncturing may differ from one subframe to another.

  • Patent number: 10531430
    Abstract: A user equipment (UE) provides service continuity when the UE is about to move out of coverage of a Multimedia Broadcast Multicast Service (MBMS). The UE: receives MBMS data via an MBMS bearer; detects that the UE is suffering from a bad MBMS bearer condition; informs a server of the bad MBMS conditions to initiate switching to unicast; wherein, if there is downlink data to deliver during switching, the UE begins to receive the downlink data via unicast and to continues to receive downlink data via the MBMS bearer until the switching to the unicast bearer is complete. The UE is configured to determine a quality of the MBMS bearer relative to a threshold, which is dependent on service type, for indicating that the MBMS bearer quality is not acceptable. When the threshold is reached, the UE sends a message to the server.

  • Patent number: 10531483
    Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.
