  • Cooperative multi-band operation schemes in wireless local area networks
    Patent number: 11134518
    Abstract: A cooperative multi-band wireless station architecture that enables full duplex operations of wireless stations (STAs). Such an STA includes a WIFI transceiver and one or more additional transceivers. The two transceivers (and the associated channels) operate in mutually exclusive WIFI bands or different types of protocols and therefore can transmit and/or receive simultaneously without signal interference to each other. The multiple transceivers can perform independent clear channel assessment (CCA) and then simultaneously perform signal transmission or reception jointly or independently. In a cooperative multi-band operation, one channel may be used as an independent assistant channel and responsible for supplying assistant information relevant to a transmission opportunity (TXOP) for the other channel (primary channel) to take corresponding actions.

  • Transmission diversity for FBE idle period handling
    Patent number: 11115161
    Abstract: Scheduling around frame based equipment (FBE) idle periods reduces the flexibility of scheduling and partitioning. This leads to a latency caused by waiting for the next downlink scheduling opportunity and skipping over unused uplink scheduling slots. According to certain aspects, to reduce overhead caused by idle time and ensure full downlink scheduling, a base station (BS) alternates between idle periods and channel occupancy time every fixed frame period with one or more other synchronized BSs, between components carriers of the BS, or both. Thus, a BS can always schedule downlink on a carrier during an idle period scheduled for a different BS and/or a different carrier.

  • Dual connectivity flow control
    Patent number: 11089512
    Abstract: User equipment (UE) can be connected to both a first base station and a second base station. A flow controller at the first base station can determine packet latency goals associated with packets. The flow controller can also determine connection latencies associated with a first connection from the first base station to the UE and a second connection from the second base station to the UE, where one leg of a split bearer passes from the first base station to the UE over the first connection and another leg of the split bearer passes from the first base station to the second base station and then to the UE over the second connection. The flow controller can route packets with lower packet latency goals via the leg of the lower-latency connection, and route other packets with higher packet latency goals over the leg of the higher-latency connection.
