  • Publication number: 20240098760
    Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to transmission of a multicast message via a common frequency resource (CFR) in a full duplex slot. The CFR may be positioned within the downlink bandwidth parts (BWP)s configured for a group of user equipments (UE)s such that each UE in the group may monitor for and receive the multicast message. The network may indicate the frequency position of the CFR to the group of UEs. The frequency resources (e.g., the resource blocks) configured for downlink for a UE may be different between half duplex slots and full duplex slots. The network and the UE may determine the active CFR for a full duplex slot based on the resources configured for the full duplex slot. The UE may monitor for and receive a multicast transmission in the active CFR in the full duplex slot.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a group of transmission configuration indicator states including a first subset associated with a first bandwidth part and a second subset associated with a common frequency resource. The UE may determine, based on the group of transmission configuration indicator states, a transmission configuration indicator state list arrangement indicating a first state list associated with the first bandwidth part and a second state list associated with the common frequency resource. The UE may select, based on the transmission configuration indicator state list arrangement, a transmission configuration indicator state sharing scheme or a transmission configuration indicator state separation scheme. The sharing scheme may include at least one transmission configuration indicator state that may be common between a unicast transmission configuration and a multicast transmission configuration.

  • Patent number: 11937236
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an acknowledgment feedback configuration for providing feedback for semi-persistent scheduling (SPS) downlink shared channels (e.g., SPS group-common physical downlink shared channels (PDSCHs), SPS unicast PDSCHs, etc.). For example, the acknowledgment feedback configuration may include separate resources for transmitting acknowledgment feedback for unicast downlink shared channels and for transmitting acknowledgment feedback for group-common downlink shared channels or may include common resources for transmitting acknowledgment feedback for both unicast downlink shared channels and group-common downlink shared channels. In some examples, the UE may multiplex acknowledgment feedback for a set of group-common downlink shared channels with additional acknowledgment feedback for other downlink channels.

  • Patent number: 11935634
    Abstract: A system for predicting and summarizing medical events from electronic health records includes a computer memory storing aggregated electronic health records from a multitude of patients of diverse age, health conditions, and demographics including medications, laboratory values, diagnoses, vital signs, and medical notes. The aggregated electronic health records are converted into a single standardized data structure format and ordered arrangement per patient, e.g., into a chronological order. A computer (or computer system) executes one or more deep learning models trained on the aggregated health records to predict one or more future clinical events and summarize pertinent past medical events related to the predicted events on an input electronic health record of a patient having the standardized data structure format and ordered into a chronological order.

  • Patent number: 11937129
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for establishing rules for scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to avoid confusion at a base station and a user equipment (UE). In one example, when flow control feedback from a UE is disabled for a downlink data transmission, the UE may still operate according to a timing for reporting flow control feedback for the downlink data transmission. In this example, the UE may drop (e.g., refrain from decoding) other downlink data transmissions based on the timing for reporting flow control feedback. In another example, when flow control feedback from a UE is disabled for a downlink data transmission, other downlink data transmissions to the UE may be scheduled according to one or more rules to avoid confusion.

  • Publication number: 20240089997
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

  • Patent number: 11910319
    Abstract: The present disclosure relates to transmitting and receiving a group wake-up signal (WUS) in conjunction with an ungrouped WUS. A base station may group one or more UEs in a UE group, while other UEs may not be assigned to a UE group. The configuration of WUS resources and WUS sequences for grouped UEs and other UEs is a challenge. The base station may transmit, to one or more UEs in the UE group, a resource allocation of a group WUS resource within a set of WUS resources associated with a paging occasion that is assigned to the one or more UEs in the UE group. A UE, after receiving the resource allocation, may determine a location of the group WUS resource within the set of WUS resources. The UE may monitor for a group WUS at the determined location in the resource allocation of the group WUS resource.
