  • Patent number: 11652668
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit to a user equipment (UE) over a control channel (e.g., a downlink control channel) and the UE may monitor for the control channel in a control resource set (CORSET). The control channel and the CORESET may be associated with a set of transmission configuration indicator (TCI) states. The base station and the UE may identify an association between the resources of the CORESET and the set of TCI states based on a frequency division multiplexing (FDM) mapping between the resources of the CORESET and the set of TCI states. In some examples, the association may be a fixed rule at the UE. In other examples, the base station may signal the association to the UE via control signaling. The UE may decode the control channel based on the FDM mapping.

  • Patent number: 11637784
    Abstract: A mechanism is provided to maximize utilization of internal memory for packet queuing in network devices, while providing an effective use of both internal and external memory to achieve high performance, high buffering scalability, and minimizing power utilization. Embodiments initially store packet data received by the network device in queues supported by an internal memory. If internal memory utilization crosses a predetermined threshold, a background task performs memory reclamation by determining those queued packets that should be targeted for transfer to an external memory. Those selected queued packets are transferred to external memory and the internal memory is freed. Once the internal memory consumption drops below a threshold, the reclamation task stops.
