  • Event trigger for independent links
    Patent number: 11765070
    Abstract: Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

  • ON-DEMAND SCHEDULING REQUEST DESIGN
    Publication number: 20230292309
    Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

  • Cancellation of transmission occasions
    Patent number: 11758551
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may dynamically cancel and reschedule configured transmission occasions for communicating with a user equipment (UE).

  • UE capability for DMRS bundling
    Patent number: 11757592
    Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.

  • SSB structure for NR communications
    Patent number: 11751152
    Abstract: In one aspect, an extended SSB (ESSB) is provided that includes more than four symbols to facilitate UE reception of SSBs. In this aspect, the base station configures an ESSB comprising an SSB including four symbols and an initial symbol preceding the SSB. The base station transmits and the UE receives at least a portion of the ESSB. The UE processes the ESSB. Thus, higher capacity UEs can benefit from additional coding gain in the initial symbol while lower capacity UEs can switch beams to receive back-to-back ESSBs. In another aspect, a UE performs additional behaviors to receive SSBs. In this aspect, the UE receives a first SSB using a reception beam, and the UE determines to maintain the reception beam for a second SSB or to switch the reception beam during a PSS symbol of the second SSB. Thus, lower capacity UEs can also receive back-to-back SSBs.
