  • Publication number: 20250151055
    Abstract: A scheduled entity receives a communication from a scheduling entity that facilitates a configuration on how to connect with a plurality of candidate cells. The scheduled entity then exchanges information about the plurality of candidate cells with the scheduling entity via Layer 1 (L1)/Layer 2 (L2) signaling, and connects with at least one of the plurality of candidate cells based on the L1/L2 signaling and the configuration. In another example, a scheduling entity transmits a communication to a scheduled entity to pre-configure the scheduled entity on how to connect with a plurality of candidate cells. The scheduling entity then receives information about the plurality of candidate cells from the scheduled entity via L1/L2 signaling, and dynamically selects via the L1/L2 signaling at least one of the plurality of candidate cells to serve the scheduled entity.

  • Publication number: 20250151110
    Abstract: A wireless communication device has a receiver to listen to a sequence of channels. A controller responds to a preamble being detected on a first channel while the receiver is tuned to the first channel by causing the receiver to stay on the first channel and decode packet(s) associated with the preamble. The controller responds to detection of a first symbol of a first transmission protocol and the preamble not being detected to cause the receiver to stay on the first channel for a predetermined time waiting for a retry. The controller responds to detection of a second symbol of a second transmission protocol and the preamble not being detected to cause the receiver to switch to an advertising channel of the second transmission protocol. If no preambles, noise, or symbols are detected, the receiver switches to listening to a next channel in the sequence after a fixed time.

    Abstract: Methods, systems, and devices for wireless communications are described in which full-duplex communications may be configured at a serving network entity. One or more symbols of a set of symbols may be configured for full-duplex communications at the network entity, and at least a first symbol that is configured for full-duplex communications also may be configured for synchronization signal block (SSB) transmissions according to a SSB configuration. A user equipment (UE) that is configured to monitor the first symbol for a SSB may use a priority rule to determine whether to transmit an uplink communication on the first symbol, or to monitor for the SSB on the first symbol. Additionally, or alternatively, a UE may transmit capability information that indicates whether the UE supports the full-duplex operation configured in SSB symbols.
