  • Patent number: 11968153
    Abstract: To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).

  • Patent number: 11838928
    Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

  • Patent number: 11690087
    Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

  • Patent number: 11671295
    Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).

  • Patent number: 11658843
    Abstract: Full-duplex communications are provided by modifying the Media Access Control sub-layer of communication node protocols. The modification allows communication nodes to communicate with one another in full-duplex, where each node transmits and receives data simultaneously with other nodes in a single frequency. A timing of the simultaneous data transmissions, acknowledgments, and short-interframe-space waiting periods can be determined based on network-allocation-vector data transmitted in association with request-to-send or clear-to-send signals.

  • Patent number: 11503613
    Abstract: Methods and apparatus for interference discovery for full-duplex data transmission are provided. In an embodiment, a station (STA) receives a full-duplex request message from an access point (AP). The STA transmits a first full-duplex response message to the AP. The STA listens for a second full-duplex response message transmitted from a second STA to the AP. The STA determines a received power of the second full-duplex response message from the second STA to the AP. The STA receives a first trigger message from the AP. The first trigger message includes information to perform full-duplex data transmission. The STA transmits data to the AP in response to the first trigger message. The STA transmits interference information to the AP. The interference information is based on the determined received power.
